[0002] Solar photovoltaic systems are a popular product for utilizing solar energy in recent years. They use solar panels to directly convert sunlight into electricity, which is crucial for providing clean and renewable energy and reducing dependence on traditional fossil fuels.

[0003] When existing photovoltaic (PV) systems are applied to buildings, waterproofing and water drainage are required to prevent rainwater from flowing into the bottom of the PV panels and causing damage to the circuitry. Therefore, PV panels in such systems typically need to be overlapped and installed on drainage channels to facilitate drainage between adjacent panels. For example, the solar PV system and its waterproof assembly disclosed in Chinese Patent Publication No. CN 211860017 U features drainage channels on both sides of the longitudinal beam, and a support plate and fixing slot at the top center of the longitudinal beam to support the PV panels on both sides, achieving good drainage. However, this solution has a relatively complex longitudinal beam structure, consumes more materials, and has higher manufacturing costs. Utility Model Content

The pressure blocks are spaced above the support and press against the upper side of the photovoltaic panel; the tail of the bolt passes through the connecting hole of the pressure block and the through hole of the upper support plate and is detachably connected to the locking block, which is confined in the locking groove of the bottom beam.

[0006] Furthermore, two horizontally spaced clamping plates are erected in the middle of the drainage channel. The opposite surfaces of the two clamping plates each have horizontally protruding clamping edges, and a clamping groove is formed between the two clamping edges.

[0007] Furthermore, the two card plates each have a horizontally protruding support edge on their back sides; the two support edges are respectively for the bottom of the two support plates of the support component to abut against.

[0008] Furthermore, the bottom of the supporting lower plate also has reinforcing edges extending in opposite directions.

[0009] Furthermore, the opposite surfaces of the two supporting lower plates are respectively attached to the opposite back surfaces of the two card plates.

[0010] Furthermore, the upper support plate has a raised platform in the middle, with a through hole in the middle of the platform, and overlapping steps on both sides of the platform for the photovoltaic panel edges to overlap; the two lower support plates are respectively located below the two overlapping steps.

[0011] Furthermore, the pressure block includes a middle pressure block; the middle pressure block includes a pressure block body with a concave center and pressure plates respectively disposed on the horizontal sides of the top of the pressure block body. A groove is formed on the top of the pressure block body, and the bottom of the groove is provided with the connecting hole that runs vertically through the groove. The pressure plates on both sides are used to press against the top surface of the photovoltaic panels on both sides.

[0012] Furthermore, a cover plate is installed on the top of the intermediate pressure block. The cover plate includes a top arc-shaped baffle and two snap-fit ​​feet at the bottom of the arc-shaped baffle. The arc-shaped baffle extends longitudinally and is the same length as the bottom beam. The two snap-fit ​​feet extend into the grooves of each pressure block for snap-fit ​​fixation. Positioning grooves are recessed on two opposite sidewalls in the grooves. Positioning protrusions that are movably snapped into the positioning grooves are respectively protruding from the opposite sides of the two snap-fit ​​feet.

[0013] Furthermore, the pressing block includes a side pressing block, which includes a pressing block middle plate, a pressing block side plate, a pressing block support plate, and a side pressing plate; the pressing block middle plate is spaced above the middle of the support member, and the connecting hole is provided on the pressing block middle plate; the pressing block side plate and the pressing block support plate are respectively arranged one above the other on the lateral sides of the pressing block middle plate; the pressing block side plate is used to abut against the side end face of the edge photovoltaic panel; the bottom of the pressing block support plate abuts against the side of the support member support plate away from the photovoltaic panel; and the side pressing plate is arranged on the top of the pressing block side plate near the edge photovoltaic panel, and is used to press against the top surface of the edge photovoltaic panel.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] like Figures 1 to 5 As shown, a photovoltaic waterproof bracket 10 of this embodiment includes at least two bottom beams 1 and several support components 2.

[0020] like Figure 3 and Figure 4 As shown, the bottom beam 1 extends longitudinally and includes a bottom plate 11 and two side plates 12 that are laterally spaced on both sides of the bottom plate 11. A longitudinally extending drainage trough 13 is formed between the two side plates 12 and the bottom plate 11. Two laterally spaced retaining plates 14 are also erected in the middle of the drainage trough 13, and a retaining groove 15 is formed between the retaining plates 14.

[0021] Two bottom beams 1 are arranged laterally at intervals, and the space between the two bottom beams 1 is used to place the photovoltaic panel 20. Each support component 2 is distributed longitudinally at intervals on the bottom beams 1 to support and fix the photovoltaic panel 20.

[0022] The support assembly 2 includes a support member 21, a pressure block 22, a bolt 23, and a locking block 24.

[0023] The support member 21 includes an upper support plate 211 and two lower support plates 212. The upper support plate 211 is horizontally arranged, and the two lower support plates 212 are respectively horizontally spaced on both sides of the bottom of the upper support plate 211. The bottom of the lower support plates 212 abuts against the drainage groove 13 of the bottom beam 1. The top surface height of the upper support plate 211 is not lower than the top surface height of the two side plates 12 of the bottom beam 1, so as to facilitate the use of the upper support plate 211 to support the edge of the photovoltaic panel 20. A through hole 213 is provided in the middle of the upper support plate 211.

[0024] The pressure block 22 can be selected as a common center pressure block 221 or a side pressure block 222, depending on its position. Figure 3 and Figure 4 Taking the middle pressure block 221 as an example, the locking block 24 can also adopt the existing technology. The middle part of the locking block 24 has a threaded hole 241 for the tail of the bolt 23 to pass through and lock.

[0025] The pressure blocks 22 are spaced above the support member 21 and press against the upper side of the photovoltaic panel 20; the tail of the bolt 23 passes through the connecting hole 220 of the pressure block 22 and the through hole 213 of the support plate 211 and is detachably locked and fixed to the locking block 24, which is limited to the slot 15 of the bottom beam 1; thus, by locking the bolt 23 and the locking block 24, the photovoltaic panel 20 can be fixed between the pressure block 22 and the support member 21, while the support member 21 is fixed to the bottom beam 1, which can ensure that the drainage meets the requirements while supporting and fixing the photovoltaic panel 20.

[0026] The tail of the bolt 23 can also be detachably connected to the locking block 24 in other ways, and is not limited to this embodiment.

[0027] A spring washer 26 can be placed between the head of bolt 23 and pressure block 22 to improve connection stability.

[0028] Moreover, when the spaced support members 21 support the photovoltaic panel 20, they can not only facilitate the accumulated water at the edge of the photovoltaic panel 20 to flow into the drainage groove 13 of the bottom beam 1 for drainage, and prevent accumulated water from damaging the photovoltaic panel 20, but also simplify the structure of the bottom beam 1, reduce the material consumption when the bottom beam 1 is produced by extrusion, effectively reduce the production and manufacturing cost, and facilitate the improvement of product competitiveness.

[0029] In this embodiment, the middle of the upper support plate 211 protrudes upward to form a boss 214, the through hole 213 is arranged in the middle of the boss 214, and lapping steps 215 are formed on both sides of the boss 214, and the two lower support plates 212 can be respectively arranged below the two lapping steps 215; the arrangement of the lapping steps 215 can facilitate the lapping placement and positioning when the edge of the photovoltaic panel 20 is installed, and can improve the installation efficiency.

[0030] In this embodiment, the top of the opposite surfaces of the two clamping plates 14 in the middle of the bottom beam 1 are respectively transversely protruded with clamping edges 141, and the clamping groove 15 is formed between the two clamping edges 141 for limiting and fixing the clamping block 24.

[0031] The middle parts of the opposite back surfaces of the two clamping plates 14 are respectively transversely protruded with supporting edges 142, and the outer ends of the supporting edges 142 away from the clamping plates 14 can protrude upward with limiting edges 143; the two supporting edges 142 can respectively allow the bottoms of the two lower support plates 212 of the supporting member 21 to abut and be placed, which can reduce the height of the supporting member 21 and improve the structural stability; and the opposite surfaces of the two lower support plates 212 can respectively abut against the opposite back surfaces of the two clamping plates 14, which can also improve the stability during supporting and improve the supporting and fixing effect. Meanwhile, the bottoms of the lower support plates 212 can respectively extend towards opposite back directions with reinforcing edges 216, so as to improve the structural strength and supporting performance of the lower support plates 212.

[0032] In this embodiment, the longitudinal lengths of the pressing block 22 and the supporting member 21 can be the same.

[0033] As Figure 3 and Figure 4 , the pressing block 22 is a middle pressing block 221, which can be in an inverted "Ji"-shape. The middle pressing block 221 comprises a pressing block main body 223 with a concave middle part and pressing plates 224 respectively arranged on the two transverse sides of the top of the pressing block main body 223. A groove 225 is formed at the top of the pressing block main body 223, the connecting hole 220 penetrating up and down is arranged at the bottom of the groove 225, and a plurality of fixed teeth 2241 can be arranged on the bottom surface of the pressing plates 224 on both sides for pressing against the top surfaces of the photovoltaic panels 20 on both sides.

[0034] A cover plate 25 can also be installed on the top of the intermediate pressure block 221. The cover plate 25 includes a top arc-shaped baffle 251 and two snap-fit ​​feet 252 at the bottom of the arc-shaped baffle 251. The arc-shaped baffle 251 extends longitudinally and can be the same length as the bottom beam 1. The two snap-fit ​​feet 252 can extend into the grooves 225 of each pressure block 22 for snap-fit ​​fixation. Specifically, positioning grooves 2251 can be recessed on two opposite side walls of the grooves 225, and positioning protrusions 2521 protrude from the opposite sides of the two snap-fit ​​feet 252, which can be movably snapped into the positioning grooves 2251. By setting the cover plate 25, it is possible to prevent the accumulation of debris and reduce the amount of rainwater entering the drainage trough 13, thereby reducing the drainage pressure of the drainage trough 13 of the bottom beam 1.

[0035] For example Figure 5 As shown, the pressure block 22 is a side pressure block 222, including a pressure block middle plate 226, a pressure block side plate 227, a pressure block support plate 228, and a side pressure plate 229. The pressure block middle plate 226 is spaced above the middle of the support member 21, and the connection hole 220 is provided on the pressure block middle plate 226. The pressure block side plate 227 and the pressure block support plate 228 are respectively arranged one above the other on the horizontal sides of the pressure block middle plate 226. The pressure block side plate 227 is used to abut against the side end face of the edge photovoltaic panel 20. The bottom of the pressure block support plate 228 can abut against the overlapping step 215 on the side of the support plate of the support member 21 away from the photovoltaic panel 20. The side pressure plate 229 is arranged on the top of the pressure block side plate 227 near the edge photovoltaic panel 20 and is used to press against the top surface of the edge photovoltaic panel 20.

[0036] This embodiment also provides a photovoltaic system 100, which uses the aforementioned photovoltaic waterproof bracket 10 to install and fix the photovoltaic panels 20. The photovoltaic system may include several base beams 1, several support components 2, and several photovoltaic panels 20; each base beam 1 is arranged horizontally at intervals, and several support components 2 are distributed longitudinally on each base beam 1; several photovoltaic panels 20 are overlapped between adjacent base beams 1 at intervals, and the edges of the photovoltaic panels 20 are respectively installed and fixedly connected to the support components 2.

[0037] Therefore, by utilizing the structure of the photovoltaic waterproof bracket 10, the photovoltaic panel 20 can be conveniently and quickly installed and fixed through the cooperation of the pressure block 22 and the support member 21. Moreover, the support member 21 can save the manufacturing cost of the bottom beam 1, effectively reduce production costs, save resources, and is more environmentally friendly in use.
