Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic technology, specifically a waterproof photovoltaic bracket. Background Technology
[0002] Photovoltaic support structures are structural systems used to fix and support photovoltaic modules. Their main functions include:
[0003] Supporting photovoltaic panels: ensuring stable installation of the modules and optimizing orientation (angle, orientation) to improve power generation efficiency.
[0004] Environmental adaptability: Resisting natural conditions such as wind load, snow load, and rain erosion, extending the lifespan of photovoltaic systems.
[0005] Flexible installation: Suitable for different scenarios such as rooftops, ground surfaces, and water surfaces, meeting diverse needs.
[0006] To improve their waterproofing capabilities, existing photovoltaic (PV) mounting systems are typically designed as frame structures with a U-shaped cross-section and open ends. While this design effectively prevents rainwater accumulation, the hollow frame structure means that the PV panels are susceptible to erosion from wind and sun during long-term support and installation. This limits the overall stability and strength of the system, especially for larger or heavier PV panels, where the support and installation capacity is significantly restricted.
[0007] To address this, this technical solution designs a waterproof photovoltaic bracket. Utility Model Content
[0008] The purpose of this invention is to provide a waterproof photovoltaic bracket to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A waterproof photovoltaic support bracket includes a connecting bracket and support rods. Multiple sets of support rods are installed at the bottom of the connecting bracket via a frame and mounting bolts, rotating and fixing them at even intervals. The supporting connecting brackets are distributed according to the tilt angle required for photovoltaic panel illumination. The vertical cross-section of the connecting bracket is U-shaped. A filter screen is installed at the top of the connecting bracket to block and filter incoming rainwater to a certain extent, reducing the amount of rainwater entering while preventing the input of rainwater containing a large amount of impurities. A drain outlet is provided at the bottom of the connecting bracket for rainwater to drain under gravity. The design of the filter screen and drain outlet at both ends of the connecting bracket increases the stability of the connecting bracket ends.
[0011] Meanwhile, the connecting bracket is equipped with a drainage channel. The drainage channel, in conjunction with gravity, controls the flow of rainwater toward the drain outlet. Rainwater entering along the long top edge of the connecting bracket is directly transferred to the drainage channel. Since the amount of rainwater entering from the long top edge is limited, it is not filtered. At the same time, multiple sets of right-angle reinforcing mesh plates are installed at equal intervals along the length of the drainage channel. The inclined surface of the right-angle reinforcing mesh plates faces the top of the connecting bracket. The right-angle reinforcing mesh plates increase the connection strength inside the connecting bracket to a certain extent. Then, in conjunction with the filter screens at both ends and the drain outlet, the overall compressive strength of the connecting bracket is guaranteed.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By using filters to block impurities and reduce the amount of rainwater entering, combined with a multi-stage drainage design including drainage channels, outlets, and passages, rainwater is quickly diverted and discharged, effectively preventing water accumulation and erosion.
[0014] By setting a right-angle reinforcing mesh plate inside the connecting bracket and forming a linkage support with the filter and drainage outlet, the overall compressive and deformation resistance of the bracket is significantly enhanced, making it suitable for large-mass photovoltaic panels.
[0015] The drainage mesh area assists in drainage when there is excessive rainwater, avoids clogging at the right-angle reinforced mesh plate, and ensures that drainage efficiency and structural stability are maintained simultaneously.
[0016] The angle can be adjusted by the support rod to match different tilt requirements; the material can be selected from aluminum alloy, steel or composite materials to meet diverse installation scenarios such as roofs and ground. Attached Figure Description

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] Please see Figures 1-4 A waterproof photovoltaic support bracket includes a connecting bracket 10 and support rods 11. Multiple sets of support rods 11 are provided and are evenly and rotatably fixed to the bottom of the connecting bracket 10 via a rod frame 12 and mounting bolts 13. The supporting connecting bracket 10 is distributed according to the tilt angle required for photovoltaic panel illumination. The vertical cross-section of the connecting bracket 10 is U-shaped. A filter screen 15 is installed at the top of the connecting bracket 10. Under the action of the filter screen 15, rainwater entering is blocked and filtered to a certain extent, reducing the amount of rainwater entering while preventing the input of rainwater containing a large amount of impurities. A drain outlet 16 is opened at the bottom of the connecting bracket 10 for rainwater to drain under gravity. The filter screen 15 and drain outlet 16 installed at both ends of the connecting bracket 10 increase the stability of the ends of the connecting bracket 10.
[0027] Meanwhile, a drainage channel 14 is provided inside the connecting bracket 10. The drainage channel 14, in conjunction with gravity, controls the rainwater to be transported towards the drain outlet 16. Rainwater entering along the long top edge of the connecting bracket 10 is directly transferred to the drainage channel 14. Since the amount of rainwater entering from the long top edge is limited, it is not filtered. At the same time, multiple sets of right-angle reinforcing mesh plates 17 are installed at equal intervals along the length of the drainage channel 14. The inclined surface of the right-angle reinforcing mesh plate 17 faces the top of the connecting bracket 10. The right-angle reinforcing mesh plate 17 increases the connection strength inside the connecting bracket 10 to a certain extent. Then, in conjunction with the filter screens 15 at both ends and the drain outlet 16, it ensures the overall compressive strength of the connecting bracket 10.
[0028] Specifically, the right-angle reinforcing mesh plate 17 has a drainage channel 18 parallel to the length of the connecting bracket 10. When rainwater flowing along the drainage groove 14 reaches the right-angle reinforcing mesh plate 17, some of it flows through the drainage channel 18, and some flows directly down the slope of the right-angle reinforcing mesh plate 17. At the same time, to prevent the drainage groove 14 from becoming clogged due to excessive rainwater, a downward-penetrating drainage mesh area 19 is provided on the drainage groove 14 corresponding to the root of the slope of the right-angle reinforcing mesh plate 17. By connecting the drainage mesh area 19 with the outside, the rainwater blockage at the right-angle reinforcing mesh plate 17 is reduced, that is, the rainwater discharge is accelerated, and the overall stability of the connecting bracket 10 is ensured.
[0029] In this embodiment of the invention, the support rod 11 is provided with mounting holes, which, together with anchor bolts and other structures, fix the support rod 11.
[0030] The connecting bracket 10 and the support rod 11 are usually made of aluminum alloy, steel or composite materials, etc.
[0031] Among them, the aluminum alloy bracket is lightweight and corrosion-resistant, making it suitable for rooftops and small to medium-sized projects;
[0032] The high strength of the steel frame makes it suitable for large-scale ground power stations;
[0033] Composite material scaffolds, such as carbon fiber reinforced plastic (CFRP), are used in special environments;
[0034] The selection of the above materials depends on the specific circumstances, and will not be elaborated upon or limited here.
[0035] In one embodiment of the present invention, the right-angle reinforced mesh plate 17 is made of the same material as the connecting bracket 10, ensuring that the strength remains consistent after installation with the connecting bracket 10;
[0036] Meanwhile, the right-angle reinforced mesh plate 17 and filter screen 15 are welded onto the connecting bracket 10 to maintain the integration after connection and installation;
[0037] When mounting bolt 13 is used to rotatably connect support rod 11 and frame 12, it needs to be fixed with the help of nuts and other structures. At the same time, the length of support rod 11 at different positions is designed according to the tilt angle of connecting bracket 10, which will not be described in detail here.
[0038] As a preferred embodiment of the present invention, since the focus of this technical solution is on the waterproofing and strength enhancement design of the inside and both ends of the connecting bracket 10, the connection form and structural relationship between the connecting bracket 10 and the photovoltaic panel can be referred to the existing connection principle between the photovoltaic panel and the bracket, and will not be described in detail here.
[0039] For example: horizontal or vertical guide rails (aluminum alloy / galvanized steel) are pre-installed on the top of the connecting bracket 10. The photovoltaic panel is connected to the guide rail by clamps or pressure blocks. The guide rail spacing is adjusted to match the size of the photovoltaic panel, so that the photovoltaic panel is installed on the connecting bracket 10.
[0040] The connection methods between the connecting bracket 10 and the photovoltaic panel include:
[0041] Fixture fixing: Use aluminum alloy or stainless steel clamps (such as edge clamps and center clamps) to clamp the photovoltaic panel frame, and then fix the clamps to the bracket guide rail with bolts. Suitable for photovoltaic panels with frames.
[0042] Bolt penetration: For frameless double-glass modules, holes need to be pre-drilled at the corresponding positions on the bracket. Waterproof bolts are used to penetrate the pre-reserved mounting holes in the photovoltaic panel, sealed with rubber gaskets, and directly fixed to the bracket.
[0043] Block fixing: The edges of the photovoltaic panel are pressed together by horizontal or vertical blocks, and the bottom of the blocks is fixed to the bracket rail with bolts. This method is commonly used in rooftop distributed projects.
[0044] The working process of this utility model:
[0045] Rainwater treatment: When rainwater enters from the top of the connecting bracket 10, the filter screen 15 filters impurities and reduces the amount of rainwater entering, and some rainwater flows directly into the drainage channel 14 along the long top edge.
[0046] Drainage and diversion: Rainwater in the drainage channel 14 flows to the drainage outlet 16 under the action of gravity. When passing through the right-angle reinforced mesh plate 17, part of it flows through the drainage channel 18 and part flows down the slope to the lower layer; excess rainwater is quickly discharged through the drainage mesh area 19.
[0047] Stable structure: The right-angle reinforced mesh plate 17 is integrated with the connecting bracket 10 by welding, and with the reinforcement design of the filter screens 15 at both ends and the drain outlet 16, it can resist wind load and photovoltaic panel pressure.
[0048] Installation and adjustment: The support rod 11 is rotatably connected to the rod frame 12 by the mounting bolt 13. The length is adjusted to adapt to the tilt angle of the connecting bracket 10, depending on the anchor bolts being fixed to the mounting surface.
[0049] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.
[0050] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
