In the solar LED street lamp system, the problem that needs very much attention to the structure is the wind design. The wind is mainly divided into two major blocks, one for the windshield of the battery assembly bracket, and the second is the windshield of the light lever. The following is analyzed in the above two pieces.
(1) Solar LED street light solar battery assembly bracket windshield
According to the technical parameters of the solar LED street lamp manufacturers, the solar cell module can withstand to 2700Pa. If the wind is selected to be 27m / s (equivalent to ten typhoon), depending on the non-stick fluid mechanics, the battery pack is only 365Pa. Therefore, the component itself can completely withstand the wind speed of 27 m / s and not damaged. Therefore, the key to the design is to consider the connection of the battery pack bracket and the solar LED street light pole.
The connection design of the battery component bracket and the solar lamp pole is fixedly connected using a bolt bar.
(2) Solar LED street lamp pole windshield
The parameters of the solar LED street light are as follows: Battery board inclination A = 16o light pole height = 5M design selection Solar LED streetlight lever bottom weld widthδ= 4mm solar LED street light pole bottom outer diameter = 168mm
The weld is on the surface of the lamp to destroy the surface. Solar LED Street Light Bar Destructive Finding Torque W Calculation Point P to the Battery Board Fidel Mount F Wide Board F Wide PQ = [5000 (168 6) / TAN16O]×SIN16O = 1545mm = 1.545m. Therefore, the role of the wind load in the sneakers of the solar LED street light pole M = f×1.545.
The maximum allowable wind speed according to the design of 27M / s, 2×The basic load of the 30W double-lamp head solar LED street lamp is 730N. Consider 1.3 safety factor, f = 1.3×730 = 949n. So M = f×1.545 = 949×1.545 = 1466N.m. Depending on the derivation of mathematics, the resistance of the circular designs surface W =π×(3R2δ 3Rδ2δ3). In the above formula, R is the inner diameter of the ring,δIt is a ring width. Destructive surface resistance W =π×(3R2δ 3Rδ2δ3) =π×(3×842×4 3×84×42 43) = 88768mm3 = 88.768×10-6 m3 The stress caused by the moment of wind load in the destructive surface = m / w = 1466 / (88.768×10-6) = 16.5×106PA = 16.5 MPA
Anti-theft design of solar LED street lamp system
It should also pay attention to anti-theft work, many times, because of the negligence of construction, there is no effective anti-theft, leading to the solar LED street light storage battery, solar LED street light battery board, but not only affects normal lighting, but also caused Unnecessary property losses. At present, it is a potent anti-theft measures in the current engineering case, solar LED stream battery, solar LED street light storage is a effective anti-theft measures. Theft of the battery board is mainly due to the low or climb around the solar LED street light pole, so the height of the solar LED street light pole is preferably 5m or more.
Waterproof design of solar LED street lamp system
The waterproof of the solar LED street light controller, most of the controller is installed in the lampshade, and the solar LED street light storage box is generally not invested. However, in the actual engineering case, some because of improper installation, will follow the controller terminal due to rainwater Wiring flow into the controller causes short circuit. Therefore, it should be noted when the controller terminal internal cable is bent into a U-shaped and solid, exposed to the external cable is also fixed as a U-shaped, so that the rain can not be short-circuited, and can be inside and outside. Waterproof glue is applied at the line interface to waterproof.
