Description

Technical Field

[0001] This application relates to the field of drainage channel technology, and more particularly to a drainage channel and a photovoltaic panel assembly. Background Technology

[0002] Photovoltaic panels, as the core component of solar power generation systems, are widely used in residential rooftops, industrial plants, and large-scale ground-mounted power plants. During the installation of photovoltaic systems, drainage channels are usually installed between photovoltaic panels or between photovoltaic panels and the roof to guide rainwater out and prevent water accumulation from damaging the roof structure and the photovoltaic system.

[0003] Because photovoltaic panels and drainage channels are exposed to the outdoor environment for extended periods, rainwater runoff, wind-borne dust, fallen leaves, and other environmental debris can easily accumulate in the drainage channels. During rainfall, these deposits can block drainage channels, reduce drainage efficiency, and even cause rainwater backflow or leakage, affecting the safe operation and lifespan of the photovoltaic system. Utility Model Content

[0004] In view of this, this application provides a drainage channel and a photovoltaic panel assembly, with the aim of solving one of the technical problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, this application provides a drainage channel, comprising: Fixed groove; The movable groove is at least partially embedded in the fixed groove; An elastic element is held between the movable groove and the fixed groove; A top cover is provided over the opening of the fixed groove. A movable lever has its fulcrum fixed to the fixed groove. One end of the lever is connected to the top cover, and the other end is connected to the movable groove. When the movable groove is empty, it is close to the top cover. When there is rainwater in the movable groove, it gradually moves away from the top cover.

[0006] In an optional embodiment, when the movable tank is vacant, there is a gap between the top cover and the movable tank.

[0007] In an optional embodiment, the movable lever includes a rod body and a fulcrum pivot, a first end pivot, and a second end pivot disposed on the rod body. The fulcrum pivot is located on the side of the fixed groove away from the movable groove. The first end pivot is connected to the top cover. The fixed groove has a through hole, and the second end pivot passes through the through hole and is connected to the movable groove.

[0008] In an optional embodiment, the cross-section of the through hole is arc-shaped.

[0010] In an optional embodiment, the movable tank includes a first bottom plate and a first side plate and a second side plate connected to the first bottom plate. The first bottom plate and the cover plate are arranged at a distance from each other, and the first side plate and the second side plate are arranged at a distance from each other. The end of the first side plate away from the first bottom plate is closer to the cover plate than the end of the second side plate away from the first bottom plate.

[0011] In an optional embodiment, the first side plate is disposed close to the connecting plate, and the end of the first side plate is bent toward the connecting plate.

[0012] In an optional embodiment, the fixing groove includes a second base plate and a third side plate and a fourth side plate connected to the second base plate. The second base plate and the cover plate are arranged at intervals relative to each other, and the third side plate and the fourth side plate are arranged at intervals relative to each other. The end of the third side plate away from the second base plate is further away from the cover plate than the end of the fourth side plate away from the second base plate. The end of the third side plate away from the second base plate is lower than the end of the first side plate, and the end of the fourth side plate away from the second base plate is higher than the end of the second side plate. The elastic element is located between the first base plate and the second base plate.

[0013] In an optional embodiment, the number of the movable groove, the fixed groove, the elastic element, the movable lever, and the elastic element is two. The two fixed grooves are symmetrically spaced apart, the two elastic elements are symmetrically spaced apart, the two movable grooves are symmetrically spaced apart, the connecting plate is disposed between the two movable grooves, and the two movable levers are symmetrically arranged and respectively connected to the top cover.

[0014] Secondly, this application provides a photovoltaic panel module, comprising: The drainage trough described in any of the foregoing embodiments; A photovoltaic panel, wherein the photovoltaic panel is inclined, the fixing groove is connected to the lower edge of the photovoltaic panel, and when the drainage groove is empty, there is a gap between the top cover and the lower edge of the photovoltaic panel.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: This application proposes a drainage channel, including a channel body, a movable channel body, an elastic element, a top cover, and a movable lever.

When the movable channel body is empty, it is close to the top cover. When there is rainwater in the movable channel body, it moves away from the top cover. When the movable channel body is empty (on a sunny day), it is close to the top cover, reducing the gap between the top of the movable channel body and the top cover, reducing the entry of leaves and other debris into the movable channel body and blocking the drainage channel, thus improving drainage efficiency. When there is rainwater in the movable channel body, it gradually moves away from the top cover, increasing the gap between the top cover and the movable channel body, accelerating the entry of rainwater into the movable channel body, and improving drainage efficiency.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of this application provides a drainage trough 100, which includes a fixed trough body 110, a movable trough body 120, an elastic element 130, a top cover 140, and a movable lever 150.

[0025] The fixed trough 110 provides support for the movable trough 120. For example, the movable trough 120 is elongated, and the fixed trough 110 is also elongated. The movable trough 120 and the fixed trough 110 are fitted with a clearance, which allows the movable trough 120 to move relative to the fixed trough 110. This also reduces the amount of leaves and debris entering the gap between the fixed trough 110 and the movable trough 120, thus reducing the impact on the movement of the movable trough 120.

[0026] The movable groove 120 is at least partially embedded in the fixed groove 110. For example, the bottom of the movable groove 120 is nested in the fixed groove 110, and the top of the movable groove 120 is exposed in the fixed groove 110, so that there is a space for movement between the fixed groove 110 and the movable groove 120.

[0027] The elastic element 130 abuts between the movable groove 120 and the fixed groove 110, and the elastic element 130 is used to provide a thrust for the movement of the movable groove 120. In one embodiment, the elastic element 130 is a spring, a rubber block, or the like.

[0028] The top cover 140 is installed over the opening of the fixed trough 110. The top cover 140 is used to reduce the gap between the fixed trough 110 and the movable trough 120, thereby reducing the impact on the movement of the movable trough 120.

[0029] The movable lever 150 is used to adjust the relative position of the movable trough 120 and the top cover 140. Specifically, the fulcrum of the movable lever 150 is fixed to the fixed trough 110, one end of the lever is connected to the top cover 140, and the other end is connected to the movable trough 120. Thus, when the movable trough 120 is empty, it moves closer to the top cover 140, reducing the gap between the top of the movable trough 120 and the top cover 140, decreasing the amount of debris such as leaves entering the movable trough 120 and blocking its drainage channels, thereby improving drainage efficiency. When there is rainwater in the movable trough 120, it gradually moves away from the top cover 140, increasing the gap between the top cover 140 and the movable trough 120, accelerating the entry of rainwater into the movable trough 120, and further improving drainage efficiency.

[0030] In some embodiments, when the movable slot 120 is vacant, there is a gap between the top cover 140 and the movable slot 120.

[0031] Understandable, such as Figure 1As shown, when the drainage trough 100 is set at the lower edge of the photovoltaic panel 200, a small gap is left between the cover plate 141 and the frame of the photovoltaic panel 200, allowing smaller dust and sand to enter the movable trough 120. These fine dust particles will not cause blockage of the movable trough 120, and will also prevent dust from accumulating on the surface of the photovoltaic panel 200, which is beneficial to improving the solar energy absorption efficiency of the photovoltaic panel 200.

[0032] In some embodiments, the movable lever 150 includes a rod 152 and a fulcrum shaft 151, a first end shaft 153 and a second end shaft 154 disposed on the rod 152. The fulcrum shaft 151 is disposed on the side of the fixed groove 110 away from the movable groove 120. The first end shaft 153 is connected to the top cover 140. The fixed groove 110 has a through hole 114. The second end shaft 154 passes through the through hole 114 and is connected to the movable groove 120.

[0033] In one embodiment, such as Figure 2 As shown, the pivot shaft 151 is fixedly connected to the side of the fixed groove 110 away from the movable groove 120, and the middle part of the rod 152 is rotatably connected to the pivot shaft 151, so that the rod 152 can rotate around the pivot shaft 151.

[0034] The first end shaft 153 is rotatably connected to the top cover 140, and the second end shaft 154 is rotatably connected to the movable groove 120. The top cover 140 and the movable groove 120 are connected by the two end shafts respectively to realize the linkage control between the two. The through hole 114 structure is set to facilitate the insertion and fixation of the second end shaft 154, simplifying the assembly process.

[0035] In some embodiments, the cross-section of the through hole 114 is arc-shaped, and by providing the through hole 114, the size of the gap between the movable groove 120 and the top cover 140 is defined. For example... Figure 2 As shown, when the second end shaft 154 moves to its lowest position, the first end shaft 153 moves to its highest position, and the top cover 140 moves closer to the fixed trough 110. At this time, the gap between the top cover 140 and the fixed trough 110 is minimal, preventing debris from entering and accumulating in the movable trough 120, which would affect drainage during rainy weather. When the second end shaft 154 moves to its highest position, the first end shaft 153 moves to its lowest position, and the top cover 140 moves away from the fixed trough 110. At this time, the gap between the top cover 140 and the fixed trough 110 is maximum, allowing rainwater to flow into the movable trough 120 more quickly, thus accelerating drainage.

[0036] It needs to be explained, such as Figure 1 As shown, there are multiple movable levers 150, which are spaced apart along the extension direction of the fixed groove 110. Correspondingly, there are multiple through holes, and each movable lever 150 has a corresponding through hole 114.

[0037] In some embodiments, the top cover 140 includes a cover plate 141 and a connecting plate 142. The cover plate 141 is disposed at the opening of the fixed groove 110, and the connecting plate 142 is disposed on the side of the cover plate 141 facing the fixed groove 110 and located on the side of the fixed groove 110 away from the movable groove 120.

[0038] like Figure 4 As shown, the cover plate 141 is used to prevent debris such as leaves from entering the movable trough 120. The gap between the cover plate 141 and the fixed trough 110 is a channel for dust or rainwater to enter the movable trough 120. The connecting plate 142 is mainly used to connect with the movable lever 150, so that the cover plate 141 and the movable trough 120 are linked together.

[0039] In some embodiments, the movable tank 120 includes a first base plate 121 and a first side plate 122 and a second side plate 123 connected to the first base plate 121.

[0040] like Figure 4 As shown, the first base plate 121 and the cover plate 141 are arranged at intervals relative to each other, and the first side plate 122 and the second side plate 123 are arranged at intervals relative to each other. The end of the first side plate 122 that is away from the first base plate 121 is closer to the cover plate 141 than the end of the second side plate 123 that is away from the first base plate 121.

[0041] One end of the first side plate 122 and the second side plate 123 are connected to the first bottom plate 121, and the other end extends toward the cover plate 141. The end of the first side plate 122 is closer to the cover plate 141, so that at least part of the movable groove 120 is exposed to the fixed groove 110, which makes it convenient to remove the movable groove 120 during maintenance.

[0042] In some embodiments, the first side plate 122 is disposed close to the connecting plate 142, and the end of the first side plate 122 is bent toward the connecting plate 142. In this way, the movable groove 120 is limited, so as to prevent the movable groove 120 from being pressed too deeply into the fixed groove 110 by rainwater when there is too much rainwater in the movable groove 120, thus damaging the elastic element 130.

[0043] In some embodiments, the fixing groove 110 includes a second base plate 111 and a third side plate 112 and a fourth side plate 113 connected to the second base plate 111.

[0044] like Figure 4 As shown, the second base plate 111 and the cover plate 141 are arranged at intervals relative to each other, and the third side plate 112 and the fourth side plate 113 are arranged at intervals relative to each other. The end of the third side plate 112 that is away from the second base plate 111 is further away from the cover plate 141 than the end of the fourth side plate 113 that is away from the second base plate 111. By lowering the height of the end of the third side plate 112, part of the movable trough 120 is exposed, which facilitates maintenance.

[0045] In some embodiments, such as Figure 4 As shown, the end of the third side plate 112 away from the second bottom plate 111 is lower than the end of the first side plate 122. When the movable groove 120 is pressed into the fixed groove 110, the third side plate 112 provides support to the first side plate 122, preventing the movable groove 120 from being completely embedded in the fixed groove 110.

[0046] In some embodiments, such as Figure 4 As shown, the end of the fourth side plate 113 away from the second bottom plate 111 is higher than the end of the second side plate 123. The end of the fourth side plate 113 is bent towards the third side plate 112. By setting the fourth side plate 113, the movable groove 120 is limited, so that the movable groove 120 can move relative to the fixed groove 110 without coming out of the fixed groove 110.

[0047] In some embodiments, the elastic element 130 is located between the first base plate 121 and the second base plate 111.

[0048] In one embodiment, the elastic element 130 includes a plurality of springs spaced apart along the extension direction of the fixed groove 110, providing sufficient support to lift the movable groove 120 and keep the top cover 140 and the fixed groove 110 in a "normally closed state" on sunny days, preventing leaves and other debris from entering and accumulating in the movable groove 120.

[0049] In some embodiments, the number of movable groove 120, fixed groove 110, elastic element 130, movable lever 150 and elastic element 130 is two.

[0050] like Figure 3 and Figure 4 As shown, two fixed grooves 110 are symmetrically spaced apart, two elastic elements 130 are symmetrically spaced apart, two movable grooves 120 are symmetrically spaced apart, a connecting plate 142 is located between the two movable grooves 120, and two movable levers 150 are symmetrically arranged and connected to the top cover 140 respectively.

[0051] like Figure 4 As shown, the longitudinal section of the top cover 140 is T-shaped, which simplifies the structure of the top cover 140.

[0052] This application provides a photovoltaic panel assembly 1000, which includes a drainage channel 100 and a photovoltaic panel 200 as described in any of the foregoing embodiments.

[0053] In some embodiments, such as Figure 3 and Figure 4As shown, the photovoltaic panel 200 is inclined, and the fixed trough 110 is connected to the lower edge of the photovoltaic panel 200. When the drainage trough 100 is empty, there is a gap between the top cover 140 and the lower edge of the photovoltaic panel 200, allowing smaller dust and sand to enter the movable trough 120. These fine dust particles will not cause blockage of the movable trough 120, and will also prevent dust from accumulating on the surface of the photovoltaic panel 200, which is beneficial to improving the solar energy absorption efficiency of the photovoltaic panel 200. Meanwhile, on sunny days, by narrowing the gap between the top cover 140 and the fixed trough 110, debris such as leaves is prevented from entering and accumulating in the movable trough 120. On rainy days, rainwater flows into the movable trough 120 to wash away the dust inside, without reducing drainage efficiency. As the rainfall increases, the amount of rainwater flowing into the movable trough 120 gradually increases, causing the movable trough 120 to be gradually pressed down. Under the action of the movable lever 150, the top cover 140 is gradually lifted. As the rainfall increases, the gap between the top cover 140 and the fixed trough 110 gradually widens, making drainage smoother and improving drainage efficiency.
