Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module dustproof technology, specifically a photovoltaic module dustproof structure. Background Technology

[0002] Photovoltaic modules, also known as photovoltaic panels, are components that can convert solar energy into electrical energy. When using photovoltaic panels, in order to prevent water and dust from accumulating on the surface of the photovoltaic panels, drainage mud-guiding clips are often installed on the surface of the photovoltaic panels to drain water and dust.

[0003] The drainage and mud-draining clamp utilizes the physical properties and characteristics of polymer materials to disrupt the surface tension of the water accumulation area during rain. This allows water and dust at the bottom edge of the photovoltaic module frame to be guided to flow out as water accumulates. This effectively solves the problem of water and dust accumulation at the bottom edge of the photovoltaic module frame from the source (during the water accumulation stage).

[0004] Existing drainage and mud-removing clips are generally one-piece structures with non-adjustable size, and can only be installed on the frame of photovoltaic panels of one thickness. Different sizes of drainage and mud-removing clips need to be customized for photovoltaic panels of different thicknesses, which has poor versatility. Based on this, a dustproof structure for photovoltaic modules is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof structure for photovoltaic modules in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof structure for a photovoltaic module, including a water guide component, wherein the water guide component is composed of a 7-shaped water guide clamp, a supporting base plate, and a vertical guide groove. The supporting base plate is fixed to the bottom of the vertical part of the 7-shaped water guide clamp, and the vertical guide groove is opened in the vertical part of the 7-shaped water guide clamp and completely penetrates the vertical part of the 7-shaped water guide clamp and the vertical guide groove.

[0007] The 7-shaped water guide clamp is slidably mounted with a clamping assembly via a vertical guide groove. The clamping assembly includes a clamping unit and a self-locking unit.

[0008] The clamping unit is used to clamp the bottom of the photovoltaic panel frame to fix the water guide to the photovoltaic panel frame;

[0009] The self-locking unit is used to achieve one-way self-locking between the clamping unit and the vertical part of the 7-shaped water guide clamp, so as to prevent the clamping unit from moving downward due to vibration, which would cause the water guide to loosen and fall off.

[0010] As a further embodiment of this utility model: the clamping unit includes a side-convex clamping plate, a protective rubber pad, and a W-shaped spring sheet;

[0011] The side-convex clamp is slidably connected to the inner side of the vertical guide groove and extends to the front and rear ends of the vertical part of the 7-shaped water guide clamp. The side-convex clamp is distributed above the vertical guide groove. The W-shaped spring is distributed between the side-convex clamp and the vertical guide groove. The upper and lower ends of the W-shaped spring are glued and fixed to the lower surface of the side-convex clamp and the upper surface of the vertical guide groove, respectively. The W-shaped spring is used to provide an upward pushing force to the side-convex clamp, so that the side-convex clamp fits tightly with the bottom of the photovoltaic panel frame, thereby achieving the clamping and fixing of the water guide component and the photovoltaic panel frame.

[0012] The protective pad is glued to the upper surface of the side-convex clamp located at the rear end of the vertical part of the 7-shaped water guide clamp, which is used to increase the friction between the side-convex clamp and the bottom of the photovoltaic panel frame.

[0013] As a further improvement of this utility model: the self-locking unit includes a through groove, an elastic pressure plate, and a locking rod;

[0014] The through groove is opened on the upper surface of the side-inverted convex clamp located at the front end of the vertical part of the 7-shaped water guide clamp, and completely penetrates to the lower surface of the side-inverted convex clamp. One end of the elastic pressure plate is fixed to the bottom end of the side-inverted convex clamp, and the top end of the elastic pressure plate extends through the through groove to the top of the side-inverted convex clamp.

[0015] The clamping rod is fixed to the top of the elastic pressure plate. The front end face of the vertical part of the 7-shaped water guide clamp is provided with an inclined groove. The clamping rod is engaged in the inclined groove to realize the downward movement limit of the side-convex clamping plate.

[0016] As a further improvement of this utility model: the inclined slots are symmetrically arranged in two sets with the vertical guide slot as the center, and the two sets of inclined slots include multiple inclined slots that are uniformly arranged in the vertical direction.

[0017] As a further improvement of this utility model: the locking rod protrudes from both sides of the elastic pressure plate and engages synchronously with two horizontally aligned inclined locking slots.

[0018] As a further improvement of this utility model, the maximum unfolded height of the W-shaped spring sheet is greater than the height of the vertical part of the 7-shaped water guide clamp.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By setting up an adjustable, tilted convex clamp, the water guide component can be clamped and fixed to the photovoltaic panel frame at different heights, further improving the versatility of the water guide component. In addition, through the cooperation of elastic pressure plate, clamping rod and inclined slot, the downward movement limit of the tilted convex clamp can be realized, thus avoiding the situation where the tilted convex clamp moves downward due to vibration and the water guide component becomes loose, further improving the installation stability of the water guide component.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 In this embodiment of the utility model, a dustproof structure for a photovoltaic module includes a water guide 1. The water guide 1 is composed of a 7-shaped water guide clamp 101, a supporting base plate 102, and a vertical guide groove 103. The supporting base plate 102 is fixed to the bottom of the vertical part of the 7-shaped water guide clamp 101, and the vertical guide groove 103 is opened in the vertical part of the 7-shaped water guide clamp 101 and completely penetrates the vertical part of the 7-shaped water guide clamp 101 and the vertical guide groove 103.

[0027] The 7-shaped water guide clamp 101 is slidably mounted with a clamping component 2 via a vertical guide groove 103. The clamping component 2 includes a clamping unit and a self-locking unit.

[0028] The clamping unit is used to clamp the bottom of the photovoltaic panel frame to fix the water guide 1 to the photovoltaic panel frame;

[0029] The self-locking unit is used to achieve one-way self-locking between the clamping unit and the vertical part of the 7-shaped water guide clamp 101, so as to prevent the clamping unit from moving downward due to vibration, causing the water guide 1 to loosen and fall off.

[0030] The clamping unit includes a side-convex clamping plate 201, a protective rubber pad 205, and a W-shaped spring sheet 206;

[0031] The side-protruding clamp 201 is slidably connected to the inner side of the vertical guide groove 103 and extends to the front and rear ends of the vertical part of the 7-shaped water guide clamp 101. The side-protruding clamp 201 is distributed above the vertical guide groove 103. The W-shaped spring piece 206 is distributed between the side-protruding clamp 201 and the vertical guide groove 103. The upper and lower ends of the W-shaped spring piece 206 are glued and fixed to the lower surface of the side-protruding clamp 201 and the upper surface of the vertical guide groove 103, respectively. The W-shaped spring piece 206 is used to provide an upward pushing force to the side-protruding clamp 201, so that the side-protruding clamp 201 is tightly attached to the bottom of the photovoltaic panel frame, thereby realizing the clamping and fixing of the water guide 1 and the photovoltaic panel frame.

[0032] The protective pad 205 is glued and fixed to the upper surface of the side-convex clamp 201 located at the rear end of the vertical part of the 7-shaped water guide clamp 101, in order to increase the friction between the side-convex clamp 201 and the bottom of the photovoltaic panel frame.

[0033] The self-locking unit includes a through groove 202, an elastic pressure plate 203, and a locking rod 204;

[0034] The through groove 202 is opened on the upper surface of the side-inverted convex clamp 201 at the front end of the vertical part of the 7-shaped water guide clamp 101, and completely penetrates to the lower surface of the side-inverted convex clamp 201. One end of the elastic pressure plate 203 is fixed to the bottom end of the side-inverted convex clamp 201, and the top end of the elastic pressure plate 203 extends through the through groove 202 to the top of the side-inverted convex clamp 201.

[0035] The clamping rod 204 is fixed to the top of the elastic pressure plate 203. The front end face of the vertical part of the 7-shaped water guide clamp 101 is provided with an inclined groove 104. The clamping rod 204 is engaged in the inclined groove 104 to realize the downward movement limit of the side-protruding clamping plate 201.

[0036] Two sets of inclined slots 104 are symmetrically arranged with the vertical guide groove 103 as the center, and the two sets of inclined slots 104 include multiple inclined slots 104 uniformly arranged in the vertical direction.

[0037] The locking rod 204 protrudes from both sides of the elastic pressure plate 203 and engages synchronously with the two horizontally aligned inclined locking slots 104.

[0038] In this embodiment, the operation steps for using and installing this water guide 1 are as follows:

[0039] First, manually pinch the front end of the side-protruding clamp 201 and the elastic pressure plate 203 together, so that the elastic pressure plate 203 deforms and flips at the connection with the side-protruding clamp 201. This causes the locking rod 204 to rotate away from the vertical part of the 7-shaped water guide clamp 101, thus preventing the locking rod 204 from contacting the inclined groove 104. (It should be noted that the side view of the elastic pressure plate 203 is similar to a "2" shaped structure. When the bottom horizontal part of the elastic pressure plate 203 is pressed, its upper arc part drives the locking rod 204 away from the vertical part of the 7-shaped water guide clamp 101.) This releases the downward movement limit of the side-protruding clamp 201.

[0040] Then, a downward pulling force is applied to the side-convex clamp 201, causing the side-convex clamp 201 to compress and shrink the W-shaped spring sheet 206. When the distance between the side-convex clamp 201 and the top horizontal part of the 7-shaped water guide clip 101 is greater than the height of the photovoltaic panel frame, the side-convex clamp 201 and the top horizontal part of the 7-shaped water guide clip 101 can be fitted onto the outside of the photovoltaic panel frame, and the pulling force on the side-convex clamp 201 and the pressing force on the elastic pressure sheet 203 are released.

[0041] At this time, the elastic pressure plate 203 resets under its own elastic force, causing the clamping rod 204 to be inserted into an inclined slot 104, while the side-protruding clamping plate 201 moves upward under the action of the W-shaped spring plate 206, and finally the side-protruding clamping plate 201 fits against the bottom of the photovoltaic panel frame, realizing the clamping and fixing of the water guide 1 and the photovoltaic panel frame.

[0042] During this process, the upward movement of the side-protruding clamp 201 causes the clamping rod 204 to move upward along the inclined inner wall of the inclined groove 104. Its elastic pressure plate 203 deforms under force. When the clamping rod 204 is aligned with the second inclined groove 104, the elastic pressure plate 203 resets, causing the clamping rod 204 to be inserted into the second inclined groove 104. This process is repeated. When the side-protruding clamp 201 is attached to the bottom of the photovoltaic panel frame, the clamping rod 204 is engaged in the inclined groove 104 at the corresponding position. This structure can limit the downward movement of the side-protruding clamp 201. That is, the side-protruding clamp 201 cannot move downward without pressing the elastic pressure plate 203. This can prevent the side-protruding clamp 201 from moving downward due to vibration (e.g., the photovoltaic panel vibrates in strong winds), which would cause the water guide 1 to loosen. This further improves the installation stability of the water guide 1.

[0043] With the cooperation of the above components, the water guide 1 can be clamped and fixed with the photovoltaic panel frame of different heights, which further improves the versatility of the water guide 1. (It should be noted that the water guide 1 is a common photovoltaic module drainage clamp on the market, and its drainage principle is the same. Therefore, the structure of the water guide 1 will not be described in detail here.)

[0044] Please refer to this carefully. Figures 1-3The maximum unfolding height of the W-shaped spring clip 206 is greater than the height of the vertical part of the 7-shaped water guide clip 101.

[0045] In this embodiment: This structure allows the W-shaped spring 206 to always exert an upward thrust on the side-convex clamping plate 201, so that the side-convex clamping plate 201 and the photovoltaic panel frame have sufficient clamping force to ensure the water guide 1 is installed stably.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
