Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panel installation, and relates to a water guide component on a photovoltaic bracket. Background Art

[0002] As the basic structure supporting photovoltaic panels, photovoltaic brackets are exposed to the outdoor environment for a long time and face the influence of various natural factors such as rain, wind, sand, humidity, etc. Especially in the rainy season or humid areas, the accumulation and flow of rainwater on the photovoltaic panels may cause corrosion and rust to the photovoltaic panels and photovoltaic brackets, and even lead to safety hazards such as electrical short circuits. Therefore, it is necessary to set a water guide component on the photovoltaic bracket to guide the rainwater to the ground. In the existing water pouring components, the main water trough generally adopts a U-shaped or trapezoidal water guide trough for water guidance. However, since the bottom of the water guide trough is flat, mud and sand are easily accumulated in the water guide trough, causing rainwater to be blocked in the water guide trough or even overflow onto the photovoltaic panels, resulting in poor water guidance effect. Utility Model Content

[0003] The purpose of the utility model is to provide a water-conducting component on a photovoltaic support with good water-conducting effect in view of the above-mentioned problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A water guide assembly on a photovoltaic bracket, the photovoltaic bracket is used to install and fix a photovoltaic panel, the photovoltaic bracket includes a crossbeam, the water guide assembly is connected to the crossbeam, and is characterized in that the water guide assembly includes a connecting piece, a main water tank, a secondary water tank and a fixing piece, the main water tank is connected to the crossbeam through a connecting piece, the main water tank is an integrated structure with a roughly "w"-shaped cross-section and an "x"-shaped middle part of the cross-section, and the horizontal height of the middle part of the main water tank is higher than the horizontal heights on both sides of the main water tank, the secondary water tank is a long strip structure with an "L"-shaped cross-section, and the ends of the secondary water tank are mounted on the main water tank, the fixing piece is connected above the middle part of the main water tank, and the fixing piece is used to press down the photovoltaic panel.

[0006] When installing the photovoltaic panels, in order to stand facing the sun, the photovoltaic brackets need to fix the photovoltaic panels at a certain tilt angle, and the tilt angle is also convenient for the water guiding assembly. In this water guiding assembly, the main water trough is arranged below the gap between the two adjacent sides of the two photovoltaic panels, and the auxiliary water trough is arranged below the end of the photovoltaic panel and extends out of the end of the photovoltaic panel. The rainwater flowing down from the photovoltaic panel is guided into the main water trough through the auxiliary water trough, and the rainwater is collected and guided to be discharged from the end of the main water trough through the main water trough. The "W"-shaped structure of the main water trough makes the upper part of the grooves on both sides of the main water trough larger. At the bottom, the upper part of the groove is larger and more convenient for collecting rainwater, and the lower part is smaller, which is convenient for quickly guiding and draining rainwater. The side and lower part of the groove have a smooth transition, which is not easy to accumulate mud and sand, has a better water guiding effect, and smooth drainage. The "x"-shaped structure in the middle of the main water tank ensures the overall supporting strength while forming two upper and lower grooves. The upper groove facilitates the connection between the main water tank and the upper part and the fixing parts, and the lower groove facilitates the connection between the main water tank and the connecting parts. The fixing parts are used to assist in fixing the photovoltaic panels, and the connecting parts are used to be fixed to the crossbeams, thereby ensuring the connection stability of the entire photovoltaic system.

[0007] In the water guide assembly on the above-mentioned photovoltaic bracket, the grooves on both sides of the main water tank are water guide grooves, the bottom of the water guide groove is an arc-shaped structure, the end of the above-mentioned secondary water tank is mounted above the water guide groove, the groove in the middle and upper part of the main water tank is a fixed groove, the above-mentioned fixing part is connected to the fixed groove, and the groove in the middle and lower part of the main water tank is a connecting groove, and the above-mentioned connecting part is connected to the connecting groove.

[0008] The arc-shaped structure at the bottom of the water gutter facilitates the rapid drainage of rainwater, and mud and sand are not easily accumulated in the water gutter. The end of the auxiliary water gutter is erected above the water gutter so that the rainwater flowing through the auxiliary water gutter can be smoothly collected into the water gutter of the main water gutter. The fixing groove is used to connect the fixings, which is convenient for pressing the photovoltaic panel between the fixings and the main water gutter. The connecting groove is used to connect the connecting parts, which is convenient for the stable connection between the main water gutter and the beam.

[0009] In the water-conducting assembly on the above-mentioned photovoltaic bracket, the fixing part includes a pressure block, a bolt 1 and a slider nut. The pressure block is in an inverted "J" shape, and a through hole is provided in the middle lower part of the pressure block. The through hole matches the bolt 1 and the bolt 1 is passed through the through hole. The slider nut is in an inverted trapezoidal shape, and a lower end of the bolt is threadedly connected to the slider nut and the slider nut is slidably connected in the fixing groove.

[0010] When the fixing part is in use, bolt 1 is passed through the through hole of the pressing block and pre-tightened with the slider nut, and then the slider nut is slid from the end of the main water tank into the fixing groove, and then the edge of the photovoltaic panel is placed above the main water tank and under the pressing block, and then bolt 1 is tightened to press the upper sides of the pressing block tightly against the photovoltaic panel, so that the photovoltaic panel and the main water tank can be stably connected.

[0011] In the water-conducting assembly on the above-mentioned photovoltaic support, both sides of the main water tank have side strips protruding in the horizontal direction, and the above-mentioned secondary water tank rests on the side strips.

[0012] The structure of the side strip increases the contact area between the secondary water tank and the main water tank, making the connection between the secondary water tank and the main water tank more stable, ensuring that the water in the secondary water tank can smoothly enter the water guide tank.

[0013] In the water-conducting assembly on the above-mentioned photovoltaic support, both sides of the upper part of the fixing groove have horizontally arranged support edges, the horizontal height of the support edges is higher than the horizontal height of the side strips, and the above-mentioned photovoltaic panel rests on the support edges.

[0014] On the one hand, the structure of the supporting edge increases the contact area between the photovoltaic panel and the main water tank, thereby improving the connection stability between the photovoltaic panel and the main water tank. On the other hand, it limits the slider nut so that the slider nut will not separate from the fixing groove upward, thereby ensuring the connection stability between the fixing and the main water tank.

[0015] In the water-guiding assembly on the above-mentioned photovoltaic bracket, the connecting part includes an angle code, a second bolt and a nut. The head of the second bolt is slidably connected in the fixing groove. The second bolt passes downward through the upper part of the angle code and is threadedly connected to the nut. The angle code is connected to the crossbeam through a fastener.

[0016] The angle code is an existing technology. The main water tank and the crossbeam are stably connected by the angle code, bolt 2 and nut. Bolt 2 can slide from the end of the main water tank into the connecting groove, and the nut is connected to bolt 2 from the bottom of the angle code, which is convenient for tightening and installation.

[0017] In the water guide assembly on the above-mentioned photovoltaic support, both sides of the lower part of the fixing groove have protruding limit edges, and the distance between the two limit edges is smaller than the diameter of the two heads of the bolt.

[0018] The structure of the limiting edge has a limiting effect on the nut, and the second bolt will not fall away from the connecting groove downward, thereby ensuring the stability of the connection between the main water tank and the beam through the connecting piece.

[0019] In the water guide assembly on the above-mentioned photovoltaic bracket, the auxiliary water tank includes a horizontally arranged water guide plate and a vertically arranged baffle. The number of the auxiliary water tanks is four. The main water tank and the four auxiliary water tanks form an "I"-shaped structure. The auxiliary water tanks located on both sides of the main water tank are symmetrically arranged. The two auxiliary water tanks located on the same side of the main water tank are oppositely arranged and the baffles of the two auxiliary water tanks are located on the side away from each other.

[0020] The photovoltaic panel is installed between two auxiliary water tanks on the same side of the main water tank. The structure of the water guide plate and the baffle plate ensures that after the rainwater on the photovoltaic panel flows to the water guide plate, due to the blocking effect of the baffle plate, the rainwater can flow along the length of the water guide plate to the water guide tank that merges into the main water tank. The positional relationship between the main water tank and the four water guide plates ensures that the rainwater on the photovoltaic panel can flow into the auxiliary water tanks from both ends, and the rainwater in the four auxiliary water tanks can all be merged into the corresponding water guide tanks of the main water tank, thereby improving the water guide efficiency and allowing the rainwater to be discharged in a centralized manner.

[0021] In the water-conducting assembly on the above-mentioned photovoltaic support, the number of the fixing parts is several, and the several fixing parts are arranged along the length direction of the main water tank.

[0022] Several fixings work together to press the photovoltaic panel tightly against the main water tank, further increasing the stability of the connection.

[0023] In the water-conducting assembly on the above-mentioned photovoltaic support, the connecting members are arranged on both sides of the photovoltaic support, and the two connecting members are symmetrically connected on both sides of the crossbeam.

[0024] The two connecting pieces are symmetrically arranged on both sides of the crossbeam, and the main water tank is stably connected to the crossbeam through the two connecting pieces. After being tightened, the main water tank is not easy to shake left and right, and has higher stability.

[0025] Compared with the prior art, the water-guiding assembly on the photovoltaic bracket guides rainwater into the corresponding water-guiding trough of the main water trough through the auxiliary water trough, and the collected rainwater is discharged from the end of the main water trough through the arc structure of the water-guiding trough. The mud and sand mixed in the rainwater are not easily accumulated in the water-guiding trough, thereby ensuring that the rainwater can be discharged quickly and smoothly, improving the water-guiding effect and efficiency; the overall supporting strength is enhanced by the "x" structure in the middle of the main water trough, and the formed fixing groove is connected with the fixing piece, and the connecting groove is connected with the connecting piece, which is easy to install, so that the photovoltaic panel, the main water trough and the crossbeam are stably connected in sequence, thereby improving the connection stability.
