Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic power generation systems, and in particular relates to a photovoltaic component guide device and a photovoltaic system. Background Art

[0002] Photovoltaic modules, as devices that generate electricity through photovoltaics, can provide power for various electrical devices and are widely used in people's lives and various places. Traditional photovoltaic systems consist of photovoltaic modules and photovoltaic brackets that support the bottom of the photovoltaic modules. To better receive sunlight, photovoltaic modules are installed at a certain angle to the ground. Rainwater can effectively wash the surface of the modules. However, after rainfall, some water may remain on the bottom edge of the modules because the frame structure restricts the smooth drainage of water. When left outdoors for a long time, the evaporated water will deposit water stains and dust on the surface of the solar panels, blocking the solar panels and affecting the power generation efficiency of the photovoltaic modules.

[0003] To solve this problem, the prior art disclosed as CN220527993U proposes a photovoltaic diversion device, which includes a diversion device body, which is clamped on the bottom of the component frame, and the photovoltaic panel is fixedly installed inside the component frame. The diversion device body is composed of three parts: a clamping piece, a first diversion component, a second diversion component, and a third diversion component. The clamping seat on the first diversion component is clamped on the component frame, and one end of the clamping seat is fixed to the tip, while the end of the clamping seat away from the tip is fixed to the limit plate. When the photovoltaic diversion device is in operation, the tip can pierce the accumulated water, destroying the surface tension of the accumulated water, allowing the accumulated water to pass through the siphon port, enter the interior of the flow channel, and be discharged through the drop channel, completing the drainage of the accumulated water on the photovoltaic panel.

[0004] However, although the above device can drain water from photovoltaic panels, it simply clips the diversion unit onto the panel frame, resulting in poor fixing. In severe weather, there is a risk that the diversion unit will fall off, and long-term safety cannot be guaranteed. Therefore, it is necessary to propose a photovoltaic panel diversion device and photovoltaic system to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 7 As shown, the utility model provides a photovoltaic module diversion device, comprising a diversion unit and a clamping unit, the clamping unit is used to be clamped and installed on the frame of the photovoltaic module, and the diversion unit is used to guide the accumulated water on the photovoltaic module. Figure 1 As shown, multiple guide devices can be detachably installed on the component frame 1 at the bottom of the photovoltaic component. The number of guide devices installed on a photovoltaic component can be increased or decreased according to actual needs. For example, in this embodiment, the photovoltaic component includes a solar panel 2 and a component frame 1 encapsulated around the solar panel 2. Three guide devices are installed on the component frame 1 located at the bottom of the photovoltaic component, and the three guide devices are arranged at intervals along the length direction of the component frame 1.

[0029] Specifically, the structure of each guide device is as follows: Figure 4 As shown, the flow guide device includes a flow guide seat 3, a flow guide channel 4 and a flow guide cloth 5, wherein one end of the flow guide seat 3 is bent downward to form a clamping portion 19, and the other end of the flow guide seat 3 (the end away from the clamping portion 19) is fixed downward to a fixing plate 7 parallel to the clamping portion 19, and the fixing plate 7 is elastically connected to a clamping block 6 on the side facing the clamping portion 19, and a horizontal clamping space is formed between the clamping block 6 and the clamping portion 19, which is used to clamp and fix the flow guide device on the component frame 1 from the horizontal direction. Ear plates 11 are fixedly connected to both sides of the clamping block 6, and a splint 16 is elastically connected to the side of the ear plate 11 facing away from the flow guide seat 3, and a vertical clamping space is formed between the two splints 16 and the flow guide seat 3, which is used to clamp and fix the flow guide device on the component frame 1 from the vertical direction. The above structure constitutes a clamping unit of the flow guide device.

[0030] The structure of the diversion unit of the diversion device is as follows: the diversion channel 4 is provided inside the diversion seat 3, one end of which opens at the bottom of the clamping part 19, and the other end opens at the bottom of the clamping block 6. The entire diversion channel 4 passes through the clamping part 19, the diversion seat 3 and the clamping block 6, and the shape of the diversion channel 4 is adapted to the diversion cloth 5. One end of the diversion cloth 5 passes through the diversion channel 4 and extends from the bottom outlet of the clamping part 19, contacting the upper surface of the solar panel 2, specifically the position where the solar panel 2 is connected to the bottom component frame 1, and the other end passes through the diversion channel 4 and extends from the bottom outlet of the clamping block 6, naturally drooping downward to the outside of the component frame 1. The diversion cloth 5 uses the siphon principle to absorb the accumulated water to the diversion cloth 5, and then draws the accumulated water out through the diversion cloth 5 and drains it from the other end of the diversion cloth 5.

[0031] In the above embodiment, if Figure 5 As shown, the interior of the clamping block 6 is provided with a through groove 20 which passes through the upper and lower parts thereof. The through groove 20 serves as a section of the guide channel 4 for the guide cloth 5 to pass through. When in use, the side of the clamping block 6 facing the clamping portion 19 is pressed against the bottom surface of the component frame 1, and the side of the clamping block 6 facing away from the clamping portion 19 is fixedly connected to a plurality of first round rods 9. The bottom of the guide seat 3 is fixedly connected to a fixing plate 7 parallel to the clamping block 6, and a plurality of first cylinders 8 are fixedly connected to the side of the fixing plate 7 away from the clamping block 6. The end of the first round rod 9 away from the clamping block 6 passes through the fixing plate 7 and is inserted into the interior of the first cylinder 8. The interior of the first cylinder 8 is fixedly connected to a first spring 10, and the other end of the first spring 10 is fixedly connected to the first round rod 9. Under the action of the first spring 10, the clamping block 6 can move away from and approach the clamping portion 19, thereby forming a horizontal clamping space.

[0032] A further optimized solution is that the two side surfaces of the clamping block 6 are fixedly connected with ear plates 11, and a second cylinder 12 is rotatably mounted on the ear plate 11. The top of the second cylinder 12 is fixedly connected with an end plate 13, and the end plate 13 is in contact with the upper surface of the ear plate 11. The interior of the second cylinder 12 is slidingly connected with a second round rod 15, and the interior of the second cylinder 12 is fixedly connected with a second spring 14, and the other end of the second spring 14 is fixedly connected to the second round rod 15, and the other end of the second round rod 15 is fixedly connected with a clamping plate 16. When in use, the clamping plate 16 is clamped on the bottom of the component frame 1, and the clamping plate 16 moves away from or close to the guide seat 3 under the action of the second spring 14, thereby forming a vertical clamping space.

[0033] To further optimize the solution, the guide cloth 5 is preferably a sponge. By setting a guide channel 4, the guide cloth 5 can be easily installed. After one end of the guide cloth 5 passes through the clamp 6 and the guide channel 4 in sequence, the guide seat 3 is clamped on the component frame 1. At this time, one end of the guide cloth 5 is in contact with the solar panel 2, and the height of the other end is much lower than the solar panel 2, so that under the action of the siphon principle, the accumulated water on the solar panel 2 can be automatically discharged.

[0034] In the above embodiment, when installing the guide seat 3, first pull the clamping block 6 in the direction of the fixing plate 7, then clamp the guide seat 3 on the component frame 1, and then release the clamping block 6. Under the action of the first spring 10, the clamping block 6 can clamp the component frame 1, and then pull the clamping plate 16 downward. When the height of the clamping plate 16 is lower than the component frame 1, rotate the clamping plate 16 to the bottom of the component frame 1, and then release the clamping plate 16. Under the action of the second spring 14, the clamping plate 16 can be clamped on the component frame 1, so that the guide seat 33 can be installed more stably on the component frame 1.

[0035] To further optimize the solution, a mounting strip 18 is installed on the upper surface of the guide seat 3, and a shielding plate 17 for shielding the guide channel 4 is fixedly connected to the bottom surface of the mounting strip 18. By setting the shielding plate 17, not only the guide cloth 5 can be fixed, but also the guide channel 4 can be shielded, thereby preventing rainwater from directly acting on the guide channel 4 and affecting the service life of the guide channel 4.

[0036] like Figure 1 As shown, an embodiment of the present invention further provides a photovoltaic system, including an inclined photovoltaic assembly, the photovoltaic assembly including a solar panel 2 and an assembly frame 1 located around the solar panel, a plurality of diversion devices are detachably snapped onto the assembly frame 1 at the bottom of the photovoltaic assembly, and the diversion device is the photovoltaic assembly diversion device described in any one of the above embodiments.
