1. What is a single -arm street light

There is only one light pole of the general lighting street light. On the top of the light rod, a branch arm is equipped with a lamp head to provide public lighting. We call this street lamp as a single -arm street lamp, also known as single -arm light.Single -arm Lights are divided into ordinary sodium lamps, single -arm street lights, energy -saving lamp single -arm street lights, pyrine single -arm street lights and LED single -arm street lights.

Single -arm Lights are the most common type in road Lights. There is only one arm. The pole body uses Q235 low -carbon high -quality steel bending welding at one time. The weld is Smooth and Smooth.The appearance is beautiful, simple and Smooth, and is usually installed on both sides of the river, slope, or wider road surface to play a role in lighting road conditions and guiding safe driving.

2. What is the lamp of both arm street lights

Both arm lamps are derivative lamps of single -arm street lights, that is, two branches on the top of the light pole, two lamp heads are installed, and the roads on both sides are illuminated.

The two branches of the arms have a certain symmetry, which is more abundant than the shape of a single -arm light. Generally, it is installed on a multi -away green Belt or a road section with special lighting requirements.energy.

What is the difference between one -arm street lamp and binocular street lights

1. Different shapes

The main difference between single -arm street lights and arms street lights is the shape. Single -arm street lights are one arm, and the top of the light rod of the arms street lights has two branches, and it is symmetrical.The street lights are more beautiful.

2. Different installation environment

Single -arm street lights are suitable for wider roads such as residential areas, rural roads, factories, parks, etc., and both arm street lights are mostly used on the two -way roads on the road and some special lighting road sections that need to take into account both sides of road lighting at the same time.Essence

3. Different costs

Single -arm street lights only need to install one branches and one lamp head. The installation cost is definitely lower than the arms street lights. However, in terms of use, the arms street lights can take into account the roads on both sides with only one light pole.Installed on both sides, generally, the arms are more energy -saving and environmentally friendly.

1. Is there any radiation in the electric stove?

If there is any radiation in the electric baked oven, if there is any radiation, the answer must be radiation.However, the radiation of electric stoves is not enough to affect daily life and health, so there is no need to worry about the radiation problem of electric stoves at all.

In life, we often come into contact with two types of radiationOne is electromagnetic radiation, and the other is heat radiation.What people say can destroy human health and cause endocrine disorders to refer to electromagnetic radiation.Because the electric stove needs to be powered on, there will be certain electromagnetic radiation, but the electromagnetic radiation containing does not reach the amount that can hurt human health.Electromagnetic radiation is more TV, mobile phone and power stations, so don't worry too much about electromagnetic radiation in the electric oven.

Speaking of heat radiation, thermal radiation is generated during the conduction of thermal energy, and it is also the most common radiation in electric stoves, but thermal radiation is basically harmless to the human body.The thermal radiation generated by the electric stove is not different from the heating equipment such as the use of charcoal fire or gas stove and electric oven, so there is no need to worry about the harm of radiation in the electric stove.

2. Is the electric stove the body harmful to the body?

Baked ovenIt is divided into three types: household electric oven and food baked oven and industrial electric stoves.The hazard of food baked stoves is mainly reflected in the cooking of food.Because the use of electric barbecue is easy to grasp the temperature when barbecue, it is easy to bake the food. The burnt foods have carcinogenic substances, so it is very harmful to the body.

When baking food, inferior electric barbecues will release harmful substances, and the harm to the human body is more serious than burnt food.Generally speaking, in order to avoid harm, pay attention to the use of high -quality electric barbecues, and do not eat burnt food.

three,Introduction to electric stove

Electric grill is a cooking Tool heating with electricity. Its working principle is to use electrical energy to concentrate to the thermal regulator, and then gather it to continuously heat the food to the food.Electric grill has the characteristics of mild, fast heating, simple operation, and safer and convenient to use. Generally, there will be an overheating automatic power -off protection device, which can be used with confidence.

Do not touch the grill panel with your hands when using electric stoves to avoid high temperature burns. In addition, you need to clean the electric oven in time after use to avoid the inside of the bakery, which affects the normal use of the electric oven.

Steel Structure Sunshine room construction method

Step 1: Rust removal and rust paint of Steel Structure

Before the Steel Structure of the sun room is welded, all Square tubes should be processed to ensure that the Steel Structure is not easy to rust.

Step 2: Welding main structure

Fang steel with a specification of 80mm*80mm and a wall thickness of 3mm, welded four -corner columns according to the measurement size and design requirements, and four -sided circle beams as the main load structure of the entire sun room.The verticality of the column and the distance between the column and the column should not exceed 5mm in the positive and negative

Step 3: Welding main beam and auxiliary beam

Fang steel steel with a specification of 76mm*44mm and a wall thickness of 2.5mm. According to the design of the top surface, the beams and longitudinal beams are reasonably distributed.Here you can choose Square tubes of different wall thickness and specifications according to actual needs.During welding, the connection of the Steel Structure must be full, no fake welding, not loose, seamless, the best welding method is fish scale welding.After the Steel Structure is welded, the welding place must be polished, so as to maximize the safety of the sun room.Ensure that in future use, it can resist the strong wind attack.

Step 4: beautification of Steel Structure

After the Steel Structure is welded, the 1.2mm thick stainless steel plate can be folded by the size of the steel to wrap all the Square steel.In this way, it can prevent the wind of the Steel Structure from blowing and scraping, but also increase its aesthetics.Some people do not wrap them out of cost considerations. Instead, they do paint on Fang Steel. This is also possible, but it is generally troublesome to maintain the opponent's steel every two years, which is more troublesome.

Step 5: Sunshine house Cover

According to the welded Steel Structure, the top surface materials for the sun room can be made. You can use color steel plates, sunlight plates, single -sided tempered glass or hollow tempered glass.Single-sided tempered glass can be 8mm-12mm thick, or 5mm 9A 5mm hollow tempered glass. color steel plates can use 80mm or 120mm thick, with corrugated color steel plates.

Step 6: Make and install facade doors and windows

The facade doors and windows of the sun room can choose aluminum alloy doors and windows, broken bridge aluminum alloy doors and windows, wooden bag aluminum doors and windows or pure solid wood doors and windows.The way to open the windows and windows is generally recommended to use a flat window to ensure the sealing of the sun room. The waterproof and windproof performance is much better than the sliding window.

Step 7: waterproof of Sunshine room and doors and windows

After the above work is completed, you can seal it.For color steel plates on the top surface, generally use a foaming agent to seal the various connection points, and then use the SBS modified asphalt linker water to prevent waterproof in the binding part of the color steel plate and wall to ensure that it will not leak in the future long -term use.If you use glass as a roof, you must use structural glue, and ordinary sealing can not be used.In addition, be sure to choose the sunny weather. You must not make glue during rainy days, and you must avoid raining as soon as the glue is finished, so as to prevent rainwater from entering the glue, causing the silicone to solidify it.There will still be a honeycomb -like gap in it, causing the leakage of the sun room.

Step 8: Check and end of the sun room

After all the construction of the sun room is completed, check it to find possible hidden dangers, including structure load, layout, door and window opening smoothly, whether the waterproof treatment of top surfaces and doors and windows is omitted.clean the construction site and end.

precautions for the construction of Steel Structure Sunshine room

1. The Steel Structure house is assembled from various components. What problems should be paid attention to when building a Steel Structure house?To ensure the quality and stability of Steel Structure houses.

2. To figure out the arrangement of the original structure, choose a reasonable Steel Structure and the original structure connection position and connection form to avoid the load of Steel Structure load to destroy the original structure.

3. The force of the Steel Structure should be clear, and the transmission route of the force should be clear and concise.Due to the obvious stress vibration of the Steel Structure itself, it is necessary to accurately analyze and calculate, strictly control the structure deformation and vibration frequency of the structure, ensure the visual aesthetics of structure use, eliminate the formation of structure and human activitiesAt the same time, this can ensure the comfort during use.

1. What does it mean to complement the municipal electricity and Solar street lights

As a clean energy source, solar energy has been widely used. Solar street lights are street lights that use solar energy supply. There are many types of Solar street lights on the market.Woolen cloth?

The municipal power complementary Solar street lights, as the name suggests, connect the Solar street lights of the municipal electricity. In terms of installation, it is necessary to laid cables like traditional city circuit Lights.

The reason why the municipal electricity complementary Solar street lights occur are mainly to consider the problems of traditional Solar street lights that are not adapted to high -power light sources and cannot work properly for a long time. In order to make up for the disadvantages of Solar street lights, municipal power complementary Solar street lights appear.

Municipal Electrical Complement Solar street lights make up for the shortcomings of general Solar street lights with their special power supply methods, so that they can be competent on the main roads that have high requirements on brightness and lighting time.If you have high lighting requirements, and you want to save electricity, you might as well try to use municipal electricity -type Solar street lights.

2. There are several types of municipal power complementary Solar street lights

There are two main types of municipal power complementary Solar street lights:

1. Municipal electricity can directly supply power to the light source

This Solar street lamp is usually used to supply power. Once the battery is insufficient due to the weather or other reasons, the controller will switch the power supply line to market power supply.

2. Municipal electricity charges the battery

When this Solar street light is working, the city power does not directly supply the light source, but charges the battery; the controller of this Solar street light is to detect the charging efficiency of Solar photovoltaic boards. For exampleThe controller is rarely controlled or even stopped charging, but the weather is not good, the photovoltaic board charging efficiency is low, and the controller improves the charging power of the city power.This is to ensure that the battery electricity work needs to meet the needs of the light source through this charging method.

The two types of municipal power complementary Solar street lights have their own advantages and disadvantages. The former Solar system and municipal electricity are relatively independent. Even if the Solar system is broken, it can work normally through the municipal power system.The former saves more electricity bills.
