[0047] The technical solution provided in this application will be further described below with reference to the embodiments and drawings.

[0048] Please also refer to Figures 1 to 4 The embodiment of the present application discloses a photovoltaic panel waterproof trough 1, comprising:

[0049] The trough body 11 is a through trough that runs through the trough body 11 along its own length direction. The trough body 11 includes a bottom plate 111, side plates 112 extending upward from both side edges in the width direction of the bottom plate 111, a first partition plate 113 extending upward from the bottom plate 111 and arranged oppositely, and a support panel 115 connected to the end of the first partition plate 113 away from the bottom plate 111; wherein the first partition plate 113 is located on the inner side of the side plate 112 to separate the trough body 11 into a first trough body 116 located in the middle and a second trough body 117 located on both sides of the first trough body 116. The first trough body 116 is formed by enclosing the bottom plate 111 and the oppositely arranged first partition plate 113; the support panel 115 is used to support the ends of the adjacent photovoltaic panels 2, the first trough body 116 corresponds to the gap between the adjacent photovoltaic panels 2, and the second trough body 117 is used to discharge the liquid flowing in through the photovoltaic panels;

[0050] The driving assembly 12 is disposed in the first tank 116;

[0051] The cleaning assembly 13 is disposed in the second tank 117 . The cleaning assembly 13 is connected to the driving assembly 12 and cleans the bottom plate 111 and the side plate 112 under the drive of the driving assembly 12 .

[0052] In the embodiment of the present application, the photovoltaic panel waterproof groove 1 is set in the gap between adjacent photovoltaic panels 2, which prevents liquid (usually rainwater) from entering the building through the gap between the photovoltaic panels 2, and has a good waterproof effect. Figure 4 As shown, the length of the trough body 11 is the y-axis, the width of the trough body 11 (also the width of the base plate) is the x-axis, and the height of the trough body is the z-axis. The trough body 11 is a through-trough extending along its length, that is, the interior of the trough body 11 is continuous along the y-axis. The width of the base plate 111 is along the x-axis, that is, the two side edges of the trough body 11 extend upward to form side plates 112. The base plate 111 and the side plates 112 are connected to form the overall outline of the trough body 11.

[0053] Two first partitions 113, extending upward from the bottom plate 111 along the z-axis, are formed opposite each other. These partitions not only support the photovoltaic panels 2 but also effectively divide the space within the trough body 11 to allow for effective drainage. On the one hand, a support panel 115 is provided at one end of the first partition 113, away from the bottom plate 111. One side of the support panel 115 contacts the photovoltaic panels, thereby supporting the panels together with the side panels 112 and bottom plate 111. On the other hand, the first partition 113 separates the trough body 11 into a first trough body 116 located in the middle and second trough bodies 117 located on either side of the first trough body 116. The middle of the trough body 11 corresponds to the gap between adjacent photovoltaic panels 2. The first trough body 116 is located in the middle, meaning that the gap between adjacent photovoltaic panels 2 is located above the first trough body 116. This arrangement allows rainwater flowing through the gap between adjacent photovoltaic panels 2 to be drained through the first trough body 116.

[0054] As for rainwater flowing through the photovoltaic panel 2, since the photovoltaic panel 2 is supported by the support panel 115 and the side panel 112, most of the photovoltaic panel 2 is covered by the second trough 117. This allows rainwater flowing through the photovoltaic panel 2 to flow into the second trough 117 through the gap between the photovoltaic panel 2 and the support panel 115, and then be discharged by the second trough 117.

[0055] However, in addition to rainwater, some dust, fallen leaves, etc. will inevitably enter the second trough 117. These substances will not all be discharged to the external environment with the water flow. As the photovoltaic panel waterproof trough 1 is used, excessive accumulation of dust and the like will affect the drainage effect of the second trough 117. Therefore, the embodiment of the present application uses a driving component 12 and a cleaning component 13 to clean the second trough 117. The cleaning component 13 is placed in the second trough 117, and the driving component 12 drives the cleaning component 13 located in the second trough 117 to move in the second trough 117, thereby cleaning the second trough 117.

[0056] The drive assembly can adopt various structures. In one embodiment, the drive assembly 12 includes compressed air, a cylinder, and a piston rod. When compressed air enters the cylinder, the piston rod is acted upon by the compressed air to move linearly. The direction of the piston rod's movement is the same as the length of the tank body 11. The piston rod is connected to the fixed rod 131. The movement of the piston rod drives the fixed rod 131 to move, thereby achieving cleaning of the second tank body 117.

[0057] In another embodiment, the drive assembly 12 includes: a drive motor 121; a screw rod 122 connected to the drive motor 121 and rotated by the drive motor 121; and a moving block 123 threadedly connected to the screw rod 122 and driven by the screw rod 122 to move along the length of the tank body 11. The moving block 123 is connected to the cleaning assembly 13 via a guide hole 118, driving the cleaning assembly 13 to move. In this application, the guide hole 118 is a strip-shaped hole formed on the first partition 113 along the length of the tank body 11.

[0058] Specifically, see Figure 5 The drive assembly 12 includes a drive motor 121, a screw rod 122, and a moving block 123, wherein the drive motor 121 is fixed to a motor plate 124; the screw rod 122 is arranged on a mounting seat 125, and the mounting seat 125 includes a base fixed above the bottom plate 111 and a first side plate 126 and a second side plate 127 arranged opposite to each other in a direction perpendicular to the base. The motor plate 124 and the mounting seat 125 are fixedly connected, one end of the screw rod 122 abuts against the second side plate 127, and the other end passes through the first side plate 126 and is connected to the drive motor 121, and the drive motor 121 drives the screw rod 122 to rotate. The moving block 123 is threadedly connected to the screw rod 122, and the moving block 123 is slidably connected to the base of the mounting seat 125. As the screw rod 122 rotates, the moving block 123 slides on the base of the mounting seat 125. By adjusting the rotation direction of the screw rod 122 by the drive motor 121, the moving block 123 can slide back and forth on the base of the mounting seat 125. The extending direction of the mounting seat 125 is the same as the length direction of the tank body 11 itself. The moving block 123 is connected to the cleaning component located in the second tank body 117 through the guide hole 118 to clean the second tank body 117.

[0059] Furthermore, the drive motor 121 includes a servo motor, an AC asynchronous motor, a DC motor, a linear motor, etc. Each type of drive motor has different characteristics. For example, the servo motor has a fast response, low energy consumption and stable operation; the AC asynchronous motor has a simple structure and low cost. A suitable drive motor can be selected according to actual conditions.

[0060] Furthermore, the cleaning assembly 13 includes a fixed rod 131 and a cleaning portion 132 that are interconnected. The cleaning portion 132 contacts the side panels 112 and the bottom plate 111 corresponding to the second trough 117. The fixed rod 131 is relatively disposed in the second trough 117. One end of the fixed rod 131 is connected to the movable block 123 through the guide hole 118. As the movable block 123 moves, the fixed rod 131 reciprocates within the first trough 116 along the length of the trough body 11, thereby cleaning the second trough 117, including dust and accumulated water. The cleaning portion 132 includes one or more of a brush, a dust cloth, and a sponge.

[0061] In one embodiment, the cleaning portion 132 is a brush, and the fixed rod 131 and the brush are fixedly connected. The brush contacts the bottom plate 111 and the side plate 112. As the movable block 123 moves, the fixed rod and the brush reciprocate along the length of the tank body 11 within the second tank body 117, thereby cleaning the second tank body 117. In another embodiment, the cleaning portion 132 is a dust removal cloth, and the dust removal portion can effectively clean dust within the second tank body 117 as the fixed rod 131 moves.

[0062] Further, see Figure 1 and Figure 2 As shown, the support panel 115 has an upwardly extending waterproof rib 1151 at one end near the outer edge of the photovoltaic panel. This waterproof rib 1151 allows most of the rainwater flowing through the photovoltaic panel 2 to enter the second trough 117 and be discharged to the outside through the trough. This prevents rainwater from accumulating on the edges and back of the photovoltaic panel 2 and damaging the panel's internal wiring, reduces the impact of liquid on the photovoltaic panel 2, and increases the service life of the photovoltaic panel 2. Furthermore, when the photovoltaic panel waterproof trough is also equipped with a structure such as a pressure block assembly, this waterproof rib 1151 has further functions and effects, as described in detail below.

[0063] Furthermore, in the embodiment of the present application, the photovoltaic panel 2 and the waterproof trough are fixedly connected by a pressing block assembly 14. The pressing block assembly 14 includes a pressing block 141 and a threaded connector 142, wherein the pressing block 141 is used to overlap the gap between adjacent photovoltaic panels, and the pressing block 141 is in contact with the side of the photovoltaic panel 2 away from the support panel 115. The pressing block 141 has an opening 1411; the threaded connector 142 includes a bolt 1421 and a nut 1422 that are threadedly connected. The threaded connector 142 removably connects the photovoltaic panel 2 between the pressing block 141 and the trough body 11 through the opening 1411; the support panel 115 also includes a limit block 119 protruding toward the first trough body 116, the bolt 1421 is used to pass through the opening 1411 and then be threadedly connected to the nut 1422, and the limit block 119 is used to confine the nut 1422 in the first trough body 116. In this embodiment, the photovoltaic panel 2 and the trough body 11 form a detachable fixed connection through the threaded connector 142. When the photovoltaic panel 2 and the trough body 11 need to be separated, the threaded connector 142 can be unscrewed.

[0064] As a preferred embodiment, please refer to Figure 3 、 Figure 6The pressing block 141 includes a bottom 1412 and wings 1413 extending upward and bending outward from both ends of the bottom 1412. The wings 1413 overlap the end surface of the photovoltaic panel 2, and the bottom 1412 overlaps the waterproof rib 1151. The bottom 1412 has an opening 1411. The bottom 1412 of the pressing block 141 overlaps the waterproof rib 1151, and the nut 1422 is constrained in the first trough body 116. The bolt 1421 is threadedly connected to the nut 1422 through the opening 1411 at the bottom of the pressing block 141. This arrangement ensures that while the photovoltaic panel 2 and the photovoltaic panel waterproof trough 1 are fixedly connected, part of the clamping force is borne by the pressing block assembly 14 and the trough body 11, thereby preventing damage to the photovoltaic panel 2 due to excessive clamping force. In some embodiments, the pressing block 141 can be a block with a certain weight, which is located in the gap between adjacent photovoltaic panels and has an opening 1411 in the middle of the block.

[0065] Further, see Figures 1 to 4 The tank body 11 includes a second partition 114 arranged in the first tank body 116 along the transverse direction. The transverse direction is a direction parallel to the width direction of the tank body, that is, Figure 3 The second partition 114 is connected at both ends to the opposing first partition 113, dividing the first trough 116 into a first sub-trough 1161 closer to the base plate 111 and a second sub-trough 1162 further away from the base plate 111. The drive assembly 12 is located in the first sub-trough 1161, and the nut 1422 is located in the second sub-trough 1162. By placing the second partition 114 and the second sub-trough 1162 above the drive assembly 12 in the first sub-trough 1161, rainwater entering the first trough 116 flows out through the second sub-trough 1162, preventing rainwater from entering the first sub-trough 1161 and affecting the drive assembly 12.

[0066] As an optional embodiment, a rainproof plate is connected to the position of the second partition 114 corresponding to the driving motor 121 to further prevent rain from wetting the driving motor 121.

[0067] Furthermore, a U-shaped groove 1163 is provided in the second sub-groove 1162, and both ends of the opening of the U-shaped groove 1163 are respectively connected to the ends of the oppositely arranged support panel 115, and the nut 1422 is provided in the U-shaped groove 1163. Figure 3 It can be seen that the U-shaped groove 1163 provides more support points to support the photovoltaic panel 2, and can more evenly distribute the load from the photovoltaic panel 2 to the photovoltaic panel waterproof groove 1, thereby improving the stability between the photovoltaic panel waterproof groove 1 and the photovoltaic panel 2.

[0068] Preferably, the angle between the side plate 112 and the bottom plate 111 is equal to or greater than 90°. This arrangement can make the load distribution thereon more uniform, reduce the possibility of stress concentration, and increase structural stability.

[0069] Preferably, the trough body 11 is made of aluminum alloy. Aluminum alloy is light and low in cost. Aluminum alloy has good mechanical properties, strong strength and hardness, and good corrosion resistance, and is suitable for wide application.

[0070] Preferably, see Figure 4 The side of the support panel 115 away from the bottom plate 111 is provided with an anti-slip portion 1152, which further improves the connection stability between the photovoltaic panel 2 and the waterproof groove. The anti-slip portion can be an anti-slip pattern, a coating with a certain friction force, etc.

[0071] In the second aspect, an embodiment of the present application provides a photovoltaic power generation system, including: a photovoltaic panel waterproof trough 1 as in the first aspect; a plurality of photovoltaic panels 2, any photovoltaic panel 2 being overlapped on the supporting panel 115 and the side panel 112 of the photovoltaic panel waterproof trough 1, and the gap between adjacent photovoltaic panels 2 corresponds to the position of the first trough body 116.

[0072] Furthermore, when the support panel 115 of the photovoltaic panel waterproof trough 1 further includes an upwardly extending waterproof rib 1151 at one end near the outer edge of the photovoltaic panel 2, the edge of the photovoltaic panel 2 is located inside the waterproof rib 1151. As a result, most of the rainwater passing through the photovoltaic panel 2 flows into the second trough 117 through the gaps between the photovoltaic panel 2 and the waterproof rib 1151, and between the photovoltaic panel 2 and the support panel 115, and is then discharged through the second trough 117.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
