Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of photovoltaic flow guides, and in particular relates to a 7mm module drainage mud guide clamp. Background Technology
[0002] When it rains, the water flowing from the photovoltaic panels carries dust downwards. When this flow is blocked by the frame, and due to the surface tension of the water, a 5-6mm deep layer of gray water accumulates at the bottom edge. After the rainwater evaporates, this forms a dusty layer of varying thickness and width. This dusty layer causes severe localized shading of the photovoltaic cells, turning them from power generators into resistive elements, consuming electrical energy, and causing bypass diodes to conduct, thus reducing power generation efficiency.
[0003] Many drainage devices for photovoltaic panels have appeared on the market. Installed at the edge of the photovoltaic panel, they compensate for the height difference between the edge and the panel, thus efficiently draining greywater and preventing rainwater accumulation. With advancements in technology, photovoltaic panels are becoming increasingly thinner, and there is currently a lack of drainage clips specifically designed for thinner panels. Utility Model Content
[0004] The purpose of this invention is to provide a 7mm module drainage mud guide clamp for drainage mud guide of low-thickness photovoltaic panels, in order to meet market demand.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] The 7mm component drainage mud guide clamp includes an integrally formed upper first clamping plate and a lower second clamping plate, with a connecting plate between the first clamping plate and the second clamping plate;
[0007] A clamping groove is formed between the first clamping plate and the second clamping plate for clamping the photovoltaic panel on the side, and the spacing between the clamping grooves is 7mm.
[0008] The first clamping plate is connected to the connecting plate in an arc shape on one side, and is a free side on the other side. It is bent into the clamping groove in an arc shape. The first clamping plate extends longitudinally and is provided with multiple first pressure recesses, which are used to evenly divide the first clamping plate into multiple guide grooves.
[0009] Furthermore, each of the first clamping plates has air holes arranged in a row corresponding to a single flow channel.
[0010] Furthermore, the connecting plate has grooves along its height, and these grooves correspond to the ends of the guide channels. Circular second recesses are provided on both sides of the connecting plate.
[0011] Furthermore, one side of the second clamping plate is integrally connected to the connecting plate, while the other side is a free side and is bent outward to form a bent section.
[0012] This utility model has the following beneficial effects: The mud guide clamp is made of stainless steel and has hydrophilicity, which makes it easy to break the surface tension of the accumulated water. It uses the hydrophilicity of metal to adsorb water molecules, and then the accumulated water flows along the guide groove to achieve the effect of removing the accumulated water. It is suitable for photovoltaic panels with existing thickness, specifically about 5mm thick, and has the advantages of high clamping stability and good flow guiding effect.

[0016] Figure 3 : Schematic diagram of the bottom structure of this utility model.
[0017] The components represented by each number in the attached figure are listed below: First clamping plate 1, Second clamping plate 2, Connecting plate 3, First indentation 11, Guide groove 12, Air hole 13, Groove 31, Second indentation 32, Bending part 21. Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] like Figures 1-3 As shown: The 7mm component drainage mud guide clamp includes an integrally formed upper first clamping plate 1 and a lower second clamping plate 2, with a connecting plate 3 between the first clamping plate 1 and the second clamping plate 2; the overall structure is a stainless steel plate structure with a thickness of about 1mm, formed by two bends, and the side projection is approximately C-shaped.
[0020] A clamping groove is formed between the first clamping plate 1 and the second clamping plate 2 for clamping the photovoltaic panel on the side. The spacing between the clamping grooves is 7mm.
[0021] The first clamping plate 1 is arc-shaped and connected to the connecting plate 3 on one side, while the other side is a free side and bends into the clamping groove in an arc shape. The first clamping plate 1 extends longitudinally and is provided with multiple first pressure recesses 11, which are used to evenly divide the first clamping plate 1 into multiple guide channels 12. Specifically, the first pressure recess is a strip-shaped structure that extends along the width direction of the first clamping plate. One end extends to the free side of the first clamping plate, and the other end terminates at the connecting plate. The width is about 10mm. There are three first pressure recesses, which are evenly arranged to divide the first clamping plate into two closed guide channels in the center and two open guide channels on both sides.
[0022] The first clamping plate on the upper side is installed on the upper side of the photovoltaic panel and has a curved part on the free side to extend to the step height difference between the photovoltaic panel and the frame. The first clamping plate and the second clamping plate have the same length, both 60mm. The first clamping plate is wider, about 23mm, because it needs to extend to the photovoltaic panel. The second clamping plate is used to cooperate with the first clamping plate to form a clamping groove. It does not need to be too wide, about 13mm.
[0023] This mud guide clamp is made of stainless steel and is hydrophilic, which makes it easy to break the surface tension of the water. It uses the hydrophilicity of the metal to adsorb water molecules, and then the water flows along the guide channel to remove the water. It is suitable for photovoltaic panels with a thickness of about 5mm and has the advantages of high clamping stability and good flow guiding effect.
[0024] like Figure 1 As shown: Each of the first clamping plate 1 and each individual guide channel 12 is provided with a row of air holes 13. Three air holes are evenly distributed, each air hole is circular with a diameter of 4mm. The air holes are connected to the guide channels to balance the air pressure within the channels, allowing water to flow smoothly.
[0025] like Figure 2 As shown: The connecting plate 3 has a groove 31 along its height, which corresponds to the end of the guide channel 12. The groove is a through-type channel, corresponding to the guide channel on the inner side of the first clamping plate. The inner side has two closed guide channels, so there are two grooves, which are symmetrically arranged on the left and right sides. The hydrophilicity of the groove side is used to improve the guiding effect. The connecting plate 3 has a circular second pressure recess 32 on both sides. The second pressure recess is pressed into the clamping groove side, which serves as the installation limit for the mud guide clamp, so that after the connecting plate is installed, there is a certain gap between it and the side of the photovoltaic panel, which is equivalent to a drainage channel, so as to facilitate the rapid discharge of mud and water.
[0026] like Figure 3 As shown: The second clamping plate 2 is integrally connected to the connecting plate 3 on one side, and the other side is a free side, which is bent outward to form a bent part 21. This is used to increase the width of the clamping groove opening side of the mud guide clamp, so as to facilitate quick positioning of the clamping groove and completion of installation during installation, and can also prevent the side from scratching the surface of the photovoltaic panel.
[0027] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
