Solar energy lighting is widely used in various road lighting systems due to its advantages such as energy saving, environmental protection, and high return. However, various factors must be considered in the design. Today we will take a look at how to design a solar street lamp wind resistance system, I hope to give you some reference.
The wind resistance system in solar street lamps is mainly divided into two major blocks: one is the wind resistance design of the battery component bracket; the other is the wind resistance design of the lamp post. Details are as follows:
1. Wind resistance design of solar cell module bracket
According to the technical reference materials related to the battery module, it can be calculated that the solar cell module can withstand a strong upwind pressure of about 2700Pa. If the wind resistance system is positioned at 27m / s (equivalent to a ten-level typhoon), according to non-viscous fluid mechanics, the wind pressure that the battery assembly can withstand is only 365Pa, so it seems that the battery assembly itself can withstand 27m / s wind speed without As for damage. Therefore, the key consideration in the design is the connection between the battery assembly bracket and the lamp post.
2. Wind-resistant design of light pole
The first thing to know is some parameters designed in solar street lamps. For example, the inclination of the panel is generally 16 degrees, and the height of the lamp post is generally 5m. The width of the welding seam at the bottom of the lamp post is 4mm and the outer diameter of the bottom of the lamp post is 168mm. . The lamp pole is on the surface of the welding seam, that is, the lamp pole destruction surface. The distance from the calculation point P of the resistance moment W of the destruction surface of the lamp pole to the action line of the panel load F received by the lamp pole is PQ = [5000+ (168 + 6) / tan16o] × Sin16o = 1545mm = 1.545m. Therefore, the moment of wind load on the destruction surface of the lamp pole M = F × 1.545.
In general, if the design is based on the maximum allowable wind speed of 27m / s, the basic load of the 2 × 30W dual-lamp solar street light panel is 730N. Considering the safety factor of 1.3, F = 1.3 × 730 = 949N. The welding seam width selected by the design meets the requirements, as long as the welding quality can be guaranteed, the wind resistance of the lamp post is no problem.
Yangzhou solar street lamp manufacturers mainly produce and sell: solar street lamp series, led street lamp series, high pole lamp series, Chinese lamp series, courtyard lamp series, lawn lamp series, various other special street lamp series, undertake road lighting projects, etc.,
