Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic device technology, specifically relating to a centralized solar photovoltaic device with waterproof function. Background Technology

[0002] Centralized photovoltaic (PV) systems are large-scale, centrally constructed PV power generation systems with installed capacities typically exceeding megawatts. They are centrally connected to the grid for power transmission and are often built in open areas such as deserts and water surfaces. They consist of PV panels, support structures, inverters, and substations. The PV panel is composed of a central panel and a rectangular outer frame surrounding it. To ensure a tight connection between the panel and the frame, sealant is usually applied to the joint edges to provide sealing, waterproofing, and dustproofing.

[0003] Existing photovoltaic panels require a certain angle during use. When it rains, rainwater slides down the panels, and since there is inevitably a height difference between the panel and the frame, rainwater accumulates at the bottom edges of the panel and frame. When the sealant at the bottom edges of the panel and frame is soaked in water for a long time and then exposed to the sun, it is prone to aging and cracking, affecting the sealing and waterproofing effect and hindering the normal use of the photovoltaic device. Therefore, a new photovoltaic device needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a centralized solar photovoltaic device with waterproof function, so as to solve the problem mentioned in the background art that the sealant on the bottom of the existing photovoltaic panel and the outer frame is prone to aging and cracking due to long-term immersion in rainwater and exposure to the sun, thus affecting the sealing and waterproof performance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1 to 4 This embodiment provides a technical solution: a centralized solar photovoltaic device with waterproof function, comprising...

[0024] The plate 100 and the outer frame 400 that wraps around the outside of the plate 100, the outer frame 400 can seal and protect the plate 100;

[0025] The panel 100 includes a main board 101, an edge layer 102 wrapped around the outside of the main board 101, and a sealant 103 filled between the outer edge of the edge layer 102 and the inner wall of the outer frame 400. The sealant 103 seals and waterproofs the panel 100 and the outer frame 400 to prevent water from seeping through the gaps to the bottom of the panel 100 and thus damaging the photovoltaic device.

[0026] The protective structure 200 includes a base plate 201 disposed on the outer side of the bottom end of the outer frame 400, a connecting rod 202 fixed to the inner side of the base plate 201 and elastically connected to the outer frame 400, and a protective plate 203 fixed to the top of the base plate 201. The protective plate 203 covers the bottom sealant 103 directly above it, and the protective plate 203 can cover the bottom sealant 103 to prevent rainwater from accumulating at the bottom sealant 103, thereby enhancing the waterproof performance.

[0027] In this embodiment, preferably, the protective plate 203 includes an aluminum alloy part 2031 and a rubber part 2032. The aluminum alloy part 2031 is fixed to the top of the base plate 201, and the rubber part 2032 is fixed to the end of the aluminum alloy part 2031 and contacts the edge layer 102. The design of the rubber part 2032 improves the sealing effect on the one hand, and avoids scratching the edge layer 102 on the other hand.

[0028] In this embodiment, preferably, the protective sheet 203 further includes a sealing insertion groove 2033, which is formed on the surface of the edge layer 102 and is inserted into the rubber part 2032 to further improve the waterproof effect.

[0029] In this embodiment, preferably, the protective structure 200 further includes a connecting groove 204 formed inside the outer frame 400. The connecting rod 202 has a T-shaped structure, and the end of the connecting rod 202 is slidably embedded into the interior of the connecting groove 204 to achieve an adjustable connection between the base plate 201 and the outer frame 400. When disassembling and assembling the plate 100, the base plate 201 can be moved to separate the protective plate 203 from the plate 100, which facilitates disassembly and assembly. After installation, the base plate 201 can be moved again to allow the protective plate 203 to contact the plate 100, thereby playing a waterproof and protective role.

[0030] In this embodiment, preferably, the guard structure 200 further includes a spring 205. The spring 205 is sleeved on the outside of the connecting rod 202, and its two ends abut against the connecting groove 204 and the end of the connecting rod 202, respectively. Through the elastic force of the spring 205, the guard plate 203 can make stable contact with the plate 100.

[0031] In this embodiment, preferably, an adjustment assembly 300 is provided in the middle of the base plate 201. The adjustment assembly 300 includes an adjustment rod 301 rotatably connected inside the base plate 201, a threaded groove 303 fixed to the inner end of the adjustment rod 301, a threaded connector 302 opened inside the outer frame 400 and threadedly connected to the threaded groove 303, and a handle 304 fixed to the outer end of the adjustment rod 301. By rotating the handle 304, the base plate 201 can be moved by the adjustment rod 301, thereby adjusting the position of the base plate 201.

[0032] In this embodiment, preferably, the adjustment assembly 300 further includes a rotation anti-detachment ring 305 and a rotation anti-detachment groove 306. The rotation anti-detachment ring 305 is fixed on the surface of the adjustment rod 301 and is rotatably engaged with the rotation anti-detachment groove 306 opened inside the base plate 201. The design of the rotation anti-detachment ring 305 and the rotation anti-detachment groove 306 does not affect the rotation of the adjustment rod 301 on the one hand, and prevents the adjustment rod 301 from falling off the base plate 201 on the other hand.
