【Solar Lamp Factory School】Solar street lamp wind resistance design support

If the solar street light is installed in an area with a large annual wind volume, then the solar street light manufacturer has to pay attention to a very important issue, that is, the wind resistance design of the solar street light. The wind resistance design of solar street lights mainly considers two aspects, one is the light pole and the other is its battery components. The wind resistance design requirements of solar street lights for light poles are: the design of the solar street light with a height of 5 meters chooses the welding seam width at the bottom of the solar light u003d 4 mm. The diameter of the solar street light pole at the bottom is 168 mm. The weld surface is on the damaged surface of the lamp pole. The resistance moment W of the failure surface of the solar street light pole is calculated. The PQ of the polished pole is PQu003dF [5000+load action line distance plate (168+6)/tan16o]×sin16ou003d1545mmu003d1.545m. Therefore, the effect of wind load on the bending moment Mu003dfx1.545 of the solar street light pole. According to the design of 27m/s and the maximum wind speed, the basic load of the 2x30W double-lamp solar panel 730 considers the safety factor of 1.3, Fu003d1.3×730u003d730. So Mu003dF*1.545u003d949×1.545u003d1466N.M. According to mathematical derivation, the resistance moment of the circular damage surface Wu003dπ×(3 delta R2+3 river delta 2+3). In the above formula, R is the diameter of the circle and the width of the delta ring. Failure surface resistance moment Wu003dπ×(3+3 delta 2+3 of river delta R2)u003dπ×(3×842×84×4+3+42,43)u003d88768mmu003d88.768×10-6M3 wind load stress u003du003d1466m/W, the moment of action for damage/(88.768×10-6)u003d16.5×106 Pau003d16.5MPa＜＜215 and 215MPa are the bending strength of Q235 steel. So as long as the welding seam width of the solar street light manufacturer meets the design requirements, as long as the welding quality is guaranteed, there is no problem with the wind resistance of the solar street light pole. There is also the support of the solar street lamp wind resistance design in the solar cell module. The solar cell module can withstand wind pressure of 2700Pa. If the wind resistance coefficient is 27m/s (tenth typhoon etc.), the wind pressure of the battery module is 365Pa, , The component itself can withstand 27 m/s without damage and wind speed. In this group of battery components, the solar street light pole connection design uses the bolt pole fixed connection street lamp system bracket design.
