Solar street lamps to resist the wind solar street light price list

Solar street lamps for buried in different areas, so the first thing to consider is the wind resistance design of solar street lamps, in order to make the solar street light can be widely used in every area, yangzhou yingli solar street light wind street lamp manufacturers in the positive research



the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Because embedded in different areas, so the first thing to consider is the wind resistance design of solar street lamps, in order to make the solar street light can be widely used in every area, yangzhou yingli street lamp manufacturers in the positive research of solar street light wind resistance design. The improvement of the wind resistance design of the solar street lamp bracket of battery components according to the battery components manufacturer skills material parameters, solar energy battery components 【 Solar energy battery components is of high efficiency crystalline silicon solar cell lines of toughened glass, super white cloth, EVA, transparent TPT backboard and the composition of aluminum alloy frame. 】 The wind pressure of about 2700 pa. According to the inviscid epidemic cerebrospinal meningitis mechanics, if the wind resistance coefficient selected for 27 m/s ( Typhoon is equivalent to ten levels) , battery components of wind pressure is 365 pa. So the components can be subjected to 27 m/s wind speed and not be destroyed. In the design of street lamp system battery components support connected to the lamp pole exercise of bolt connection design freeze. The wind resistant design for 2 solar street lamp lighting lamps parameters is as follows: set A = 16 panels Angle o light pole height = 5 m design selection at the bottom of the lamp post weld width delta = = 4 mm at the bottom of the light pole diameter 168 mm weld surface where the surface damaged light pole. Light pole destruction surface surrender the moment W calculation of panels to point P to the light pole action load F the partition for the PQ = [ 5000 + ( 168 + 6) / tan【 Tangent function is the Angle theta in any right triangle, and theta corresponding to the side and the ratio of adjacent side is called the tangent. 】 16 o) ×Sin16o = = 1545毫米。 Wind load' Wind load ( 风荷载) Pressure generated by the air flow of engineering structure. 】 The role of the moment on the surface of the light pole destroy M = F *. According to the design of 27 m/s biggest willing to wind speed, the 2 x 30 w double lamp holder, changsha, photosynthetic solar energy street light panels roots load of 730 n. F = x 730 = 949 n, the safety factor of thinking. So M = F (x = 949 x = 1466 n. m。 Circular destroyed the surrender the moment W = PI * ( 3 r2δ+ 3 rδ2 +δ3) According to the mathematical deduction. The inner diameter, r is a ring type, the delta is ring width. Damaged surface surrender moment W = PI * ( 3 r2δ+ 3 rδ2 +δ3) =π×( 3×842×4+3×84×42+43) =88768mm3　　=×10- 6 m3 wind load on the destruction of torque caused by the stress = = 1466 / (M/W ×10- 6) =×106 pa = Mpa< < 215 mpa and 215 mpa is Q235 steel 【 Q235 steel is a kind of carbon structural steel. 】 The bending strength' Bending strength is refers to the material's ability to fight bend don't break, it is mainly used for examining the strength of the brittle material such as ceramic. 】 。 And our welding quality can guarantee, design selection of the weld width of moderate, light pole there is no question of wind resistance.
