Problems solved by technology

However, faster or larger-diameter hailstones can cause serious consequences such as glass cracks, glass shattering, and battery failure.
In addition, in areas with severe wind and sand, photovoltaic panels need to be cleaned after sandstorms to ensure the amount of light received by photovoltaic panels, making equipment maintenance difficult

Embodiment 1

[0052] Such as Figure 1-6 As shown, the retractable tree-like photovoltaic module in Embodiment 1 includes a pole 1, and a photovoltaic panel unit 2 with the same shape is arranged on both sides of the pole 1. The photovoltaic panel unit 2 includes a photovoltaic panel 21 and a bracket 22 that are fixedly connected. The bracket 22 is rotationally connected with the pole 1;

[0053] An L-shaped cantilever 3 is arranged on the pole 1, and the free end of the cantilever 3 is a rotating shaft, and the free end surface of the rotating shaft is connected to the first flange 4 through a bolt 11, and a shaft sleeve 23 is arranged on the bracket 22, and the rotating shaft and the shaft sleeve 23 are rotatably matched. , the axial direction of the rotating shaft is consistent with the axial direction of the strut 1; the outer periphery of the sleeve 23 is provided with a second flange 5, and several pin holes 6 are equally spaced on the first flange 4 and the second flange 5, locking ...

Embodiment 2

[0060] Such as Figure 7-8 As shown, embodiment 2 is based on embodiment 1, and the difference is that the number of the first hinged seat 91, the second hinged seat 92 and the third hinged seat 93 on the main rod 9 is five, and one of the two sides of the pole 1 The photovoltaic units 2 are arranged symmetrically, and one photovoltaic panel 21 is arranged on one side of the other four poles 1 , and two photovoltaic panels 21 are arranged on the other side.

[0061] In the normal unfolded state of Embodiment 1 and Embodiment 2, the support rod 1 is pinned to the second hinge seat 92 of the main rod 9, the second limit block 8 is on top of the cross-section of one end of the limit protrusion ring 7, and the bolt 11 Pass through the corresponding through holes of the first flange 4 and the second flange 5 and connect with nuts to lock the photovoltaic unit and the pole.

[0062] Before hail or sandstorms, remove the bolts 11 and nuts, and fold the photovoltaic panel units 2 on ...

Abstract

The invention discloses a retractable tree-shaped photovoltaic module. The retractable tree-shaped photovoltaic module comprises supporting rods; photovoltaic panel units are arranged at two sides ofeach supporting rod; each photovoltaic panel unit comprises a photovoltaic panel and a support which are fixedly connected with each other; the supports are rotationally connected with the corresponding supporting rod; locking pieces are arranged between the supports and the supporting rod and are used for locking the light receiving states and folding states of the photovoltaic panels; the photovoltaic panels in the folded states are arranged in a vertical direction and located on the light receiving side of the supporting rod; and the light receiving surfaces of the photovoltaic panels at the two sides of the supporting rod are adjacent or attached to each other. According to the retractable tree-shaped photovoltaic module, the photovoltaic panels in unfolded states receive sufficient light, the two photovoltaic panels in the folded states are arranged in the vertical direction; compared with the probability of the collision of the photovoltaic panels in the unfolded states with hailstones, the probability of the collision of the photovoltaic panels in the folded states with hailstones is reduced. The retractable tree-shaped photovoltaic module is used in a sandstorm environment;the light receiving surfaces of the photovoltaic panels are adjacent or attached to each other, so that sandy soil is hardly attached to the light receiving surfaces of the photovoltaic panels, and therefore, equipment maintenance workload is small. The invention further discloses a use method of the retractable tree-shaped photovoltaic module.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a retractable tree-shaped photovoltaic component and a method for using the same. Background technique [0002] Photovoltaic modules are generally installed in a flat manner, on the ground, roof, etc., but the prerequisite for this is to have an open and large area, which requires high geographical environment. The front protective glass of photovoltaic modules is usually made of low-iron ultra-clear tempered glass, which has a certain ability to resist shocks, that is, it can withstand general hail attacks. [0003] my country's photovoltaic module product specification GB / T9535 and the international standard IEC61215 require the anti-hail ability of photovoltaic modules to be able to resist the impact of hail with a diameter of 25mm at a speed of 23 m / s. But hailstones with faster speeds or larger diameters can cause serious consequences such as glass cracks, g...
