Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, specifically to a photovoltaic module mounting clamp. Background Technology

[0002] Photovoltaic modules are components encapsulated with glass, a backsheet, a frame, and a string of cells to convert sunlight into electrical energy. During use, these modules are secured to mounting brackets using mounting clamps. Furthermore, these clamps are also needed to secure adjacent photovoltaic modules to the mounting brackets. However, existing mounting clamps, when securing adjacent photovoltaic modules, press against the module's frame and may even extend into the area where the cells are located. This not only affects the light-receiving surface area of ​​the cells but also hinders cleaning of the cell area, resulting in significant practical limitations. Summary of the Invention

[0003] This utility model provides a photovoltaic module mounting clamp, which optimizes the structure of existing mounting clamps to solve the problem of insufficient practicality when fixing two photovoltaic modules.

[0004] This utility model provides a photovoltaic module mounting fixture, including a limiting member and a fastener. The limiting member is aligned with the frame of the photovoltaic module, and the fastener is connected to the limiting member. The limiting member has a "π"-shaped structure, including two A-sides, two B-sides, two D-sides, and one C-side. The area between the A-sides and the B-sides is a positioning area, and the fastener passes between the C-sides and the D-sides. The surface area of ​​the A-sides is smaller than that of the B-sides, and the A-sides and the C-sides include a transitional arc surface.

[0005] The mounting clamp provided by this utility model is used to fix two adjacent photovoltaic modules onto a mounting bracket. Compared with the prior art, the mounting clamp provided by this utility model includes an integrated limiting component and a fastener. The limiting component has a symmetrical structure. The frames of the photovoltaic modules to be fixed are respectively positioned in the positioning area between surface A and surface B. The fastener is used to press the gap between surface C and surface D, indirectly pressing the frames of the two photovoltaic modules to be fixed between surface A and surface B. In this utility model, the surface area of ​​surface A is smaller than that of surface B, so that the surface of the photovoltaic cell is not blocked by the mounting clamp, thus ensuring the light-receiving area of ​​the cell. At the same time, it facilitates cleaning personnel to clean the glass surface above the cell, thereby improving the practicality of the photovoltaic module mounting clamp.

[0006] Optionally, surface A includes strip-shaped protrusions.

[0007] In this design, the A-side of the mounting fixture includes strip-shaped protrusions to increase the adhesion of the A-side to the surface of the photovoltaic module frame.

[0008] Optionally, the fastener includes a bolt, a washer, and a fastening nut. The washer is in contact with the D surface, and the bolt passes through the C surface and the washer in sequence before being screwed to the fastening nut, which is partially embedded on the back of the washer.

[0009] In this design, a pad is used to be tightly attached to the D-surface on both sides of the mounting fixture to ensure that the D-surface on both sides is subjected to uniform force.

[0010] Optionally, the fastener may further include a resilient washer that is in contact with the C-surface.

[0011] In this design, an elastic washer is set between the upper end of the fastening bolt and the upper surface (C-surface) of the mounting fixture to provide a preset buffer amount when the mounting fixture is fastening the photovoltaic module, so as to avoid damaging the aluminum frame of the photovoltaic module.

[0012] Optionally, the limiting component is integrally formed.

[0013] In this design, the limiting component is integrally formed, such as by rolling or casting steel plates. Compared with welding individual parts, this integrally formed structure has stronger stability and more balanced stress distribution.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a photovoltaic module mounting clamp, which improves the practicality of mounting clamps for fixing two adjacent photovoltaic modules by optimizing the structure of existing mounting clamps.

[0017] The technical solutions in the embodiments of the application will now be clearly and completely described with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0018] A photovoltaic (PV) module is a component encapsulated with glass, a backsheet, a frame, and a string of cells to convert sunlight into electrical energy. During use, this module is fixed to a mounting bracket using mounting clamps. Furthermore, these clamps also need to secure adjacent PV modules to the mounting bracket. However, existing mounting clamps, when securing adjacent PV modules, press against the module's frame and may even extend over the area where the cells are located. This not only affects the light-receiving surface area of ​​the cells but also hinders cleanliness in the cell area, resulting in significant practical limitations. Therefore, this invention provides a PV module mounting clamp, which will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a photovoltaic module mounting fixture, including a limiting member 1 and a fastener 2. The limiting member 1 is connected to the frame of the photovoltaic module, and the fastener 2 is connected to the limiting member 1. The limiting member 1 has a "π" shaped structure, which includes two A surfaces, two B surfaces, two D surfaces and one C surface. The area between the A surfaces and the B surfaces is the positioning area, and the fastener 2 passes through the area between the C surface and the D surfaces. The surface area of ​​the A surface is smaller than the surface area of ​​the B surface, and the area between the A surface and the C surface includes a transition arc surface.

[0020] It should be noted that the aforementioned limiting component 1 is integrally formed, such as by rolling steel plate or casting. Compared with the method of welding individual parts, this integrally formed structure has stronger stability and more balanced stress distribution.

[0021] Specifically, the mounting clamp provided by this utility model is used to fix two adjacent photovoltaic modules on a mounting bracket. The limiting member 1 has a symmetrical structure. The frames of the photovoltaic modules to be fixed are respectively located in the positioning area between surface A and surface B. Fasteners 2 are used to press the gap between surface C and surface D, indirectly pressing the frames of the two photovoltaic modules to be fixed between surface A and surface B. In this utility model, the surface area of ​​surface A is smaller than that of surface B, so that the surface of the battery inside the frame of the photovoltaic module is not blocked by the mounting clamp, thus ensuring the light-receiving area of ​​the battery cells. At the same time, it is convenient for cleaning personnel to clean the glass plate surface above the battery cells, thereby improving the practicality of the photovoltaic module mounting clamp.

[0022] The aforementioned fastener 2 includes: a bolt 21, a washer 22, and a fastening nut 23. The washer 22 is in contact with surface D, and the bolt 21 passes through surface C and the washer 22 in sequence before being screwed into the fastening nut 23, which is partially embedded on the back of the washer 22. Figure 1As shown, bolt 21 passes through the upper surface (surface C) of the limiting member 1 and extends into the pad 22. The fastening nut 23 on the back of the pad 22 is nested and fixedly connected to the pad 22. By tightening bolt 21, the bolt 21 brings surface C and surface D closer together to a preset parameter, thereby indirectly compressing the gap between surface A and surface B, achieving the purpose of pressing the frame of the photovoltaic module between surface A and surface B. The aforementioned preset parameter is the preset torque. This data needs to be selected adaptively based on the material characteristics of the limiting member and the material properties of the photovoltaic module frame, etc. This embodiment does not impose specific limitations on this.

[0023] It should be noted that in the limiting member 1 of this embodiment, there is an arc-shaped transition surface between surface C and surface A. This transition surface balances the compressive stress on surface C, preventing surface C from bending and deforming due to excessive local compressive stress after the bolt 21 is tightened. In addition, in this embodiment, the pad 22 is in close contact with the D surfaces on both sides of the mounting fixture to ensure that the D surfaces on both sides are subjected to uniform force.

[0024] In some embodiments, the A-side of the aforementioned limiting member 1 includes a strip-shaped protrusion.

[0025] In this embodiment, a strip-shaped protrusion is provided on surface A of the mounting fixture to increase the adhesion of surface A to the frame of the photovoltaic module. Because surface A is in contact with the upper surface of the photovoltaic module frame and its surface area is small, when the strip-shaped protrusion acts on the surface of the photovoltaic module frame, compared with the original surface A contacting the frame of the photovoltaic module, the former can increase the pressure intensity per unit area, thereby helping to improve the surface adhesion.

[0026] In other embodiments, the aforementioned fastener 2 further includes a resilient washer that is in contact with surface C.

[0027] In this embodiment, an elastic washer is provided between the upper end of the fastening bolt 21 and the upper surface (C-surface) of the mounting clamp to provide a preset buffer amount when the mounting clamp is fastening the photovoltaic module, thereby preventing damage to the aluminum frame of the photovoltaic module. The elastic washer has two ports at different heights, i.e., a strip of steel plate is rotated around a preset value axis, and after rotation, the two ports of the steel plate are misaligned and opposite to each other.

[0028] Finally, the photovoltaic module mounting fixture provided by this utility model includes a limiting member 1 and a fastener 2. The limiting member 1 is aligned with the frame of the photovoltaic module, and the fastener 2 is connected to the limiting member 1. The limiting member 1 has a "π"-shaped structure, including two A-sides, two B-sides, two D-sides, and one C-side. The area between A-sides and B-sides is a positioning area, and the fastener 2 passes between C-sides and D-sides. The surface area of ​​A-sides is smaller than that of B-sides, and there is a transitional arc surface between A-sides and C-sides. This utility model improves the practicality of mounting fixtures for fixing two adjacent photovoltaic modules by optimizing the structure of existing mounting fixtures.

[0029] The above embodiments merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
