In the wind system, solar street lamps are mainly divided into two areas: the wind resistant design for a light pole is; Wind resistant design for battery components support is a specific situation is as follows: 1, light pole, wind resistance design of the first to know the solar street lamps in the design of some parameter
solar street light wind system is mainly divided into two parts: one is light pole of wind resistance design. The wind resistant design for battery components is a stent. Details are as follows:
1. Wind resistant design for light pole
in the first place, we need to know some design parameters of the solar street lamps, such as panel Angle is 16 degrees commonly, the height of the light pole is 5 meters, commonly selected in the design of light pole at the bottom of the weld width is 4 mm, light pole at the bottom of the outer diameter is 168 mm, the surface of the light pole is located is the surface of the breakage of the light pole. From light pole failure surface on the calculation of resistance moment W P to the light pole panel action load F the distance for the PQ = [ 5000 + ( 168 + 6) / tan16o] & times; Sin16o = 1545毫米= 1。 545米。 Therefore, the wind loads on the light pole failure moment M = F & time; 1. 545.
in general, if the maximum allowable 27 m/s wind speed is designed, it is 2 times; 30 w double burner plate solar street lamps of basic load of 730 Newton. Considering the safety coefficient is 1. 3,F = 1。 3 times; 730 = 949 cattle. Selection in the design of the weld width of conform to the requirements. As long as the welding quality can be guaranteed, light pole wind resistance, there is no problem.
2。 The wind resistant design for solar energy battery components support
according to the following technical resources related to the battery module, solar module to withstand wind pressure can be calculated approximately 2700 mpa. If the wind system in 27 meters/SEC ( Typhoon is equivalent to 10) , according to the viscous fluid mechanics, the battery pack can withstand wind pressure 365 mpa, so the battery itself seems to be able to withstand 27 m/s wind speed without damage. Therefore, in the design of the key consideration is the connection between the battery module bracket and light.
