Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components, and in particular relates to a dust accumulation prevention structure applied to photovoltaic components. Background Art

[0002] Photovoltaic modules are used outdoors year-round, subject to constant exposure to wind and sun. Maintaining proper operation and power generation efficiency in such harsh environments is a particularly pressing technical issue in current PV module reliability research. Dust obstruction is a common problem, unavoidably present on every PV module. Surface dust directly reduces the amount of light reaching the module, thereby impacting power generation and heat dissipation. Furthermore, due to the varying physical and chemical properties of different types of dust, long-term accumulation and subsequent rainwater washout can lead to dust accumulation near one side of the PV module frame. This thick layer of dust obscures the photovoltaic cells in this area, leading to a hot spot effect. Existing methods for combating dust generally rely on regular manual or machine cleaning, but this approach is costly and ineffective in areas prone to frequent sandstorms. Furthermore, cleaning thousands of PV modules in large-scale PV power plants is extremely time-consuming.

[0003] Therefore, a dust accumulation prevention structure for photovoltaic modules is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] 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.

[0026] 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.

[0027] Example 1

[0028] Reference Figure 1-Figure 3 As shown, this embodiment provides a dust accumulation prevention structure applied to a photovoltaic module, comprising:

[0029] The module frame 1 is used to fix and install the photovoltaic laminate 2. The module frame 1 includes a rectangular frame 101, and a mounting platform 102 protrudes from the inner side of the rectangular frame 101. The photovoltaic laminate 2 is fixedly connected to the mounting platform 102, and the top surface of the photovoltaic laminate 2 is flush with the top surface of the rectangular frame 101. The bottom of the rectangular frame 101 extends to form a bottom plate 103.

[0030] The bracket guide rail 3 and the bottom surface of the rectangular frame 101 are in contact with the bracket guide rail 3 , and the bracket guide rail 3 and the component frame 1 are fixedly connected through the installation component.

[0031] By setting up a component frame 1 with a mounting platform 102 on the side, the photovoltaic laminate 2 is installed on the mounting platform 102 so that the top surface of the photovoltaic laminate 2 is flush with the top surface of the rectangular frame 101, that is, the top surface of the component frame 1, and the component frame 1 is not higher than the photovoltaic laminate 2, so that rainwater or dust will not accumulate at the edge of the photovoltaic laminate 2, which can greatly reduce the adverse effects of dust accumulation on the photovoltaic component and improve the reliability and weather resistance of the photovoltaic component operation; and the specific structural design of the rectangular frame 101 top surface platform and the bottom plate 103 of the component frame 1 provides installation space for the component frame 1 to be installed on the bracket guide rail 3, which is beneficial to the installation and fixation of the component frame 1 and the photovoltaic laminate 2, making the installation more stable.

[0032] To further optimize the solution, a support plate 104 extends from the bottom surface of the mounting platform 102 toward the base plate 103 , and the bottom of the support plate 104 is fixedly connected to the base plate 103 . The base plate 103 , the support plate 104 , the mounting platform 102 and the side of the rectangular frame 101 together form a first cavity 105 .

[0033] A support plate 104 is provided below the mounting platform 102 and is fixedly connected to the bottom plate 103 extending from the rectangular frame, so that the support plate 104 can provide support for the mounting platform 102, thereby increasing the strength of the mounting platform 102 and preventing the mounting platform 102 from breaking.

[0034] According to a further optimized solution, a second cavity 106 is defined in the rectangular frame 101 .

[0035] Both the second cavity 106 and the first cavity 105 can reduce the material usage of the component frame 1 while ensuring structural strength.

[0036] In a further optimized solution, the photovoltaic laminate 2 is connected to the mounting platform 102 by gluing.

[0037] The photovoltaic laminate 2 and the mounting platform 102 are preferably bonded by means of silicone.

[0038] To further optimize the solution, the installation assembly includes an edge pressure block 4, which abuts against the top surface of the rectangular frame 101. A first bolt 5 is provided on the side of the edge pressure block 4 away from the rectangular frame 101. The first bolt 5 vertically penetrates the edge pressure block 4 and the bracket guide rail 3 and is fastened by a nut 6.

[0039] The edge pressure block 4 is overlapped on the top surface of the rectangular frame 101, and then the component frame 1 and the bracket guide rail 3 are fixedly connected by tightening the first bolt 5 and the nut 6. However, in the prior art, there is often no space reserved on the outside of the photovoltaic laminate 2, and the component frame 1 and the photovoltaic laminate 2 are fixed to the bracket guide rail 3 by gluing, which is not firm and inconvenient to install. There is also the prior art that presses the edge pressure block 4 directly on the photovoltaic laminate 2 or indirectly presses it on the photovoltaic laminate 2 through a pad for fixing. In this way, the photovoltaic laminate 2 is easily cracked or crushed due to excessive pressure, so it is not firm. Therefore, the installation of this application is more convenient, quicker and more stable.

[0040] To further optimize the solution, the edge pressure block 4 includes a first vertical plate 401, a first platform 402 is vertically fixed to the top of the first vertical plate 401, a second vertical plate 403 is vertically fixed to the end of the first platform 402 away from the first vertical plate 401, and a second platform 404 is fixed to the top of the second vertical plate 403; the bottom surface of the second platform 404 abuts the top surface of the rectangular frame 101, and the bottom surface of the first vertical plate 401 abuts the top surface of the bracket guide rail 3, and the first bolt 5 vertically penetrates the second platform 404 and the bracket guide rail 3 and is fastened by the nut 6.

[0041] The side pressing block 4 is bent to form the second platform 404 , so that the connection position of the first bolt 5 is lower than that of the photovoltaic laminate 2 , thereby preventing the first bolt 5 from being affected by dust or rainwater and sliding off.

[0042] In a further optimized solution, a side of the second platform 404 close to the photovoltaic laminate 2 is provided with a slope.

[0043] The second platform 404 has a slope on the side close to the photovoltaic laminate 2 , which helps dust and rainwater slide down the slope to the outside of the component frame 1 .

[0044] As a further optimization solution, the bottom surface of the first vertical plate 401 is extended to both sides to expand the bottom area.

[0045] After the bottom surface of the first vertical plate 401 extends to both sides to increase the bottom area, the contact area with the bracket guide rail 3 can be increased to disperse the force between the first vertical plate 401 and the bracket guide rail 3 and avoid stress concentration.

[0046] Example 2

[0047] Reference Figure 4 As shown, the anti-dust accumulation structure applied to photovoltaic modules in this embodiment is different from that in embodiment 1 only in that the mounting assembly in this embodiment includes an inner pressure plate 7, one end of the inner pressure plate 7 abuts against the top surface of the base plate 103, and the other end extends inward out of the base plate 103 and protrudes downward to abut against the bracket guide rail 3, and the inner pressure plate and the bracket guide rail 3 are fastened together by a second bolt 8.

[0048] One end of the inner pressure plate 7 abuts against the bottom plate 103 of the component frame 1, pressing the bottom plate 103 onto the bracket guide rail 3, and fastening it with the second bolt 8, thereby fixing the component frame 1 to the bracket guide rail 3, and setting the installation component on the inner side of the component frame 1, which is suitable for situations where the installation space outside the component frame 1 is small, thereby expanding the scope of application.

[0049] As a further optimization solution, anti-slip grooves are provided at the contact position between the inner pressure plate 7 and the bottom plate 103 .

[0050] The anti-slip grooves prevent the bottom plate 103 from slipping.
