Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0034] like Figures 1-4 As shown, this application provides a photovoltaic panel drainage device, comprising:

[0035] The mounting frame 1 is in the shape of a "n" and includes two clamping arms 11 and a connecting beam 12 connecting the two clamping arms 11, the inner side of the clamping arm 11 is provided with a clamping groove 101 matching the thickness of the frame of the photovoltaic panel, the clamping arm 11 is clamped on the frame of the photovoltaic panel, and the inner side of the connecting beam 12 is close to the upper edge of the lower frame of the photovoltaic panel.

[0036] The flow guide groove 2 is fixedly connected to the inner side of the connecting beam 12, the length of the flow guide groove 2 matches the length of the lower frame of the photovoltaic panel, and the side of the flow guide groove 2 away from the connecting beam 12 is a flow guide surface that is inclined downward from the central part to both sides.

[0037] A pair of flow guide pipes 3 are arranged at the connecting position of the clamping arm 11 and the connecting beam 12, the flow guide pipe 3 extends out of the connecting beam 12 and extends obliquely downward, and the water inlet of the flow guide pipe 3 is connected to the flow guide surface of the flow guide groove 2.

[0038] In use, the photovoltaic panel is clamped into the clamping groove 101 of the clamping arm 11, and a limiting block is arranged at the position of the clamping groove 101 close to the connecting beam 12, so that the inner side of the connecting beam 12 is aligned with the upper edge of the lower frame of the photovoltaic panel after the photovoltaic panel is connected to the clamping groove 101, and at this time, the lower surface of the flow guide groove 2 and the flow guide pipe 3 is in close contact with the photovoltaic panel, thereby avoiding the accumulation of water at the lower frame of the photovoltaic panel. When water flows down from the photovoltaic panel, the remaining water is guided by the flow guide groove 2 to flow to both sides and then flows into the flow guide pipe 3.

[0039] The photovoltaic panel drainage device of the present application matches the shape of the photovoltaic panel by arranging the mounting frame 1, and fixes the drainage device to the lower edge of the photovoltaic panel, at the same time, the flow guide groove 2 arranged plays a role of guiding flow, and also avoids the accumulation of water at the lower frame of the photovoltaic panel, and the flow guide pipe 3 connected to the flow guide groove 2 guides the water on the photovoltaic panel to flow to both sides of the photovoltaic panel through the flow guide groove 2 and then flows out, thereby reducing the accumulation of water on the photovoltaic panel. The device of the present application uses the above-mentioned structure to guide and drain the water on the photovoltaic panel, thereby overcoming the drawbacks of the traditional photovoltaic panel, i.e., the accumulated water at the lower frame of the photovoltaic panel invades into the photovoltaic panel and causes adverse effects on the photovoltaic panel.

[0040] As shown in Figure 1 and Figure 3 Optionally, the connecting beam 12 includes a first connecting segment 121 in the upper layer and a second connecting segment 122 in the lower layer, and the distance between the first connecting segment 121 and the second connecting segment 122 matches the thickness of the frame of the photovoltaic panel.

[0041] The inner side of the flow guide groove 2 is fixedly connected to the first connecting segment 121.

[0042] In the present application, the connecting beam 12 is designed as a two-layer structure, which can make the back of the flow guide groove 2 in a ventilated environment, and reduce the accumulation of water vapor while achieving lightweight structure.

[0043] As shown in Figure 5 , optionally, the bottom of the flow guide groove 2 is provided with a water absorption cloth 13 near the first connecting section 121, one side of the water absorption cloth 13 is fixed to the bottom of the flow guide groove 2, and the other end is suspended away from the flow guide groove 2.

[0044] In the present application, in some cases of large water flow (such as heavy rain, or using water power to clean photovoltaic panels), a small amount of water may accumulate on the back of the flow guide groove 4, that is, the upper edge of the lower frame of the photovoltaic panel. The water absorption cloth 13 can absorb these water through capillary action and discharge from the suspended side in time, and avoid the accumulation of water. The water absorption cloth 13 can be woven from chemical fiber materials to improve its service life and shorten the drying time.

[0045] As shown in Figure 6 , optionally, the water absorption cloth 13 includes a fixed section 131 connected with the flow guide groove 2 and a plurality of water guide sections 132;

[0046] The water guide section 132 is an elongated cloth strip or rope, and a plurality of water guide sections 132 are arrayed on the side of the fixed section 131 away from the flow guide groove 2;

[0047] The water guide section 132 is suspended.

[0048] In the present application, when the water flow is too large during use, a small amount of water may accumulate on the back of the flow guide groove 4, that is, the upper edge of the lower frame of the photovoltaic panel. At this time, due to the presence of the water absorption cloth 13, these water will be absorbed (capillary action) and discharged through the water guide section 132, and due to the light and thin material of the water absorption cloth 13, it can be dried quickly to avoid the retention of water.

[0049] As shown in Figure 5 , optionally, the second connecting section 122 is provided with a fixed clamp 123;

[0050] The fixed clamp 123 clamps a plurality of suspended water guide sections 132 and fixes them.

[0051] In the present application, the fixed clamp 123 can fix the water guide section 132 to avoid the water guide section 132 flying in the windy weather and being difficult to guide water.

[0052] As shown in Figure 7 , optionally, the flow guide pipe 3 is further connected with the water storage tank 4 through a pipeline.

[0053] In the present application, the water storage tank 4 can collect and reuse the water discharged from the photovoltaic panel, thereby reducing resource waste.

[0054] As Figure 8 shown, the reservoir 4 is optionally divided into a sedimentation area 42 and a reuse area 43 by a partition 41;

[0055] The sedimentation area 42 and the reuse area 43 are connected by a water pump 44;

[0056] The sedimentation area 42 is connected with the flow guide pipe 3.

[0057] In use, the water flows out through the pipeline into the reservoir 4, is deposited in the sedimentation area 42 of the reservoir 4, and the supernatant after deposition is transferred by the water pump 44 to the reuse area 43 for recycling.

[0058] A photovoltaic panel drainage device, and its working process is as follows:

[0059] In use, the two sides of the photovoltaic panel are clamped into the clamping groove 101 of the clamping arm 11, and a limiting block is arranged at the position close to the connecting beam 12 to ensure that the inner side of the connecting beam 12 is aligned with the upper edge of the lower frame of the photovoltaic panel after the photovoltaic panel is connected with the clamping groove 101, at this time, the lower surface of the flow guide groove 2 and the flow guide pipe 3 will be tightly attached to the photovoltaic panel, avoiding water accumulation at the lower edge of the photovoltaic panel. When water flows down from the photovoltaic panel, the remaining water is guided by the flow guide groove 2 to flow down to both sides and flows into the flow guide pipe 3 to flow out. The water flows out through the pipeline into the reservoir 4, is deposited in the sedimentation area 42 of the reservoir 4, and the supernatant after deposition is transferred by the water pump 44 to the reuse area 43 for recycling.

[0060] In use, when the water flow is too large, a small amount of water may accumulate at the back of the flow guide groove 4, that is, the upper edge of the lower frame of the photovoltaic panel, at this time, due to the presence of the water-absorbing cloth 13, these water will be absorbed (capillary action) and discharged through the water guide section 132, and due to the light and thin material of the water-absorbing cloth 13, it can be quickly dried to avoid water retention.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
