Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a pressing block for a photovoltaic component and a photovoltaic component having the pressing block. Background Art

[0002] Photovoltaic modules are electronic devices that use the photovoltaic effect to convert solar energy into electrical energy. They are mainly composed of photovoltaic glass, cells, backplanes, and fixed frames. Photovoltaic modules have many advantages such as energy saving and environmental protection, safety and reliability, renewable and long service life, so they are widely used in grid-connected power generation, traffic lighting, communication base stations and other fields.

[0003] At present, when installing photovoltaic modules, a pressing block is usually used to fix the photovoltaic module to a predetermined installation part (such as a roof, a carport, an outdoor light stand, etc.). Specifically, the pressing block is fixed to the predetermined installation part by screws, and the pressing block presses the photovoltaic module so that the photovoltaic module is confined between the pressing block and the predetermined installation part. However, during actual application, the photovoltaic module will be subjected to loads such as wind and snow, so that the stress on the photovoltaic module is easily concentrated near the pressing block, causing cracks or even bursting of components such as photovoltaic glass, greatly reducing the safety and service life of the photovoltaic module.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0005] In order to solve or improve to a certain extent the technical problem in the prior art that photovoltaic modules are easily damaged due to stress concentration, the utility model provides a pressing block for photovoltaic modules. The pressing block includes: a fixing plate, on which a mounting hole is provided, so that the fixing plate can be fixed on a predetermined mounting member; a connecting plate, the connecting plate having a first end and a second end opposite to each other, the first end being connected to the fixing plate, wherein a stress release hole is provided on the connecting plate; and a pressing plate, the pressing plate being connected to the second end, and the pressing plate being configured to abut against the photovoltaic module when the fixing plate is fixed on the predetermined mounting member, so as to constrain the photovoltaic module between the pressing plate and the predetermined mounting member.

[0006] It can be understood by those skilled in the art that the pressure block of the utility model includes a fixed plate, a connecting plate and a clamping plate. A mounting hole is provided on the fixed plate so that the fixed plate can be fixed on a predetermined mounting part. The connecting plate has a first end and a second end opposite to each other. The first end is connected to the fixed plate, and the second end is connected to the clamping plate so that the fixed plate and the clamping plate are connected. The clamping plate is configured to abut against the photovoltaic module when the fixed plate is fixed on the predetermined mounting part so as to constrain the photovoltaic module to the clamping block and the predetermined mounting part. Among them, a stress release hole is provided on the connecting plate. Therefore, when the photovoltaic module is subjected to a large load, the stress at the connection between the fixed plate and the predetermined mounting part can be transmitted to the connecting plate through the fixed plate, and a part of the stress is released after passing through the stress release hole, thereby correspondingly reducing the force of the clamping plate on the photovoltaic module, preventing the photovoltaic module from being damaged, and thus improving the safety and service life of the photovoltaic module.

[0007] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, the length of the stress release hole along the length direction of the connecting plate is L1, and the length along the width direction of the connecting plate is L2, wherein L1≥L2. Through the above-mentioned setting, the stress release hole can be extended roughly along the length direction of the connecting plate, that is, the stress release hole also extends roughly along the length direction of the pressing plate. In this way, the stress at the connection between the fixed plate and the photovoltaic module can be effectively released when passing through the stress release hole on the connecting plate, ensuring that the stress has sufficient release space and significantly reducing the stress transmitted to the pressing plate.

[0008] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, the diameter of the mounting hole is D, wherein L2≥D. Through the above-mentioned setting, the stress release hole can have a moderate width, so that the stress has enough release space at the stress release hole.

[0009] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, the length of the connecting plate along the length direction is L, wherein 1 / 3L≤L1≤2 / 3L. Through the above-mentioned setting, the stress release hole can have a moderate length, so as to take into account the rigidity and mechanical strength of the connecting plate on the basis of satisfying stress release.

[0010] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, the stress release hole is arranged in the middle of the connecting plate. Through the above-mentioned arrangement, the stress can be more evenly transmitted to the pressing plate through the connecting plate.

[0011] In the above preferred technical solution of the pressing block for photovoltaic modules, the stress release holes are symmetrically arranged along the vertical center line of the connecting plate to further improve the uniformity of stress conduction.

[0012] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, the stress release hole is a waist-shaped hole, a triangular hole, an arc-shaped hole or an elliptical hole to enrich the types of stress release holes.

[0013] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, the fixing plate has a first edge and a second edge opposite to each other, and the connecting plate extends vertically from the first edge and / or the second edge to the pressing plate. Through the above-mentioned arrangement, the pressing block can have a variety of structures to meet the fixing needs of different installation positions of photovoltaic modules.

[0014] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, the pressing block further comprises: a support plate, the support plate vertically extending from the first edge and / or the second edge in a direction away from the connecting plate, and the support plate is suitable for abutting against the predetermined mounting member. The provision of the support plate can further improve the reliability and stability of the pressing block in fixing the photovoltaic module.

[0015] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, the pressing plate is an arc-shaped plate protruding in a direction away from the fixing plate. The setting of the arc-shaped plate can make the pressing plate more firmly press the photovoltaic module and prevent the photovoltaic module from slipping off the pressing block.

[0016] In the preferred technical solution of the above-mentioned pressing block for photovoltaic modules, an anti-skid protrusion is formed on the pressing surface of the pressing plate suitable for abutting against the photovoltaic module. The provision of the anti-skid protrusion can increase the friction coefficient between the pressing plate and the photovoltaic module and improve the reliability of the connection between the two.

[0017] In order to solve or improve to a certain extent the technical problem that photovoltaic modules are easily damaged due to stress concentration in the prior art, the utility model provides a photovoltaic module. The photovoltaic module includes a pressing block for photovoltaic modules according to any one of the above items. By adopting the pressing block described in any one of the above items, the photovoltaic module of the utility model can effectively avoid stress concentration and improve safety and service life.

[0038] Continue to see Figure 3In one or more embodiments, the pressing block 200 includes a fixing plate 210, a connecting plate 220, a pressing plate 230 and a supporting plate 240. The fixing plate 210 has a substantially rectangular shape. Alternatively, the fixing plate 210 may also be configured in other suitable shapes, such as a square. In the assembled state, the fixing plate 210 extends substantially in the horizontal direction. The fixing plate 210 has two opposite edges, namely a first edge 211 and a second edge 212. Based on Figure 3 In the orientation shown, the first edge 211 is the front edge of the fixing plate 210, and the second edge 212 is the rear edge of the fixing plate 210. In one or more embodiments, a mounting hole 213 is provided on the fixing plate 210.

The fastener 300 may be, but is not limited to, a bolt, a nut, a screw, etc. The mounting hole 213 may be a circular hole, a waist-shaped hole, or other suitable shapes. The mounting hole 213 is arranged at the center of the fixing plate 210 to ensure the reliability of the fixation. Alternatively, the mounting hole 213 may also be arranged at other suitable positions. Alternatively, the mounting hole 213 may also be set to 2, 3, or other suitable numbers.

[0039] Continue to see Figure 3 In one or more embodiments, the connecting plate 220 is arranged on one of the two opposite edges of the fixing plate 210. Specifically, the connecting plate 220 is arranged on the second edge 212 of the fixing plate 210. Alternatively, the connecting plate 220 may also be arranged on the first edge 211 of the fixing plate 210. The connecting plate 220 is substantially perpendicular to the second edge 212 of the fixing plate 210 and faces away from the fixing plate 210 (based on Figure 3The connecting plate 220 has a first end 221 and a second end 222 opposite to each other. The first end 221 is the lower end of the connecting plate 220, and the second end 222 is the upper end of the connecting plate 220. The first end 221 of the connecting plate 220 is connected to the fixing plate 210, and the second end 222 is connected to the clamping plate 230. The connecting plate 220 has a substantially rectangular shape. Alternatively, the connecting plate 220 may also be configured to have other suitable shapes, such as a square, etc. A stress relief hole 223 is provided on the connecting plate 220. The stress relief hole 223 may be manufactured using a suitable machining process (such as a stamping process, a drilling process, etc.). In the assembled state, the compression stress generated by the fastener 300 near the mounting hole 213 will be transmitted to the connecting plate 220 through the fixing plate 210, and a part of it will be released through the stress release hole 230 arranged on the connecting plate 220, thereby effectively preventing the stress from being concentrated on the compression plate 230 and damaging the photovoltaic module 100, and ensuring the safety and service life of the photovoltaic module 100. In one or more embodiments, the stress release hole 223 is arranged in the middle of the connecting plate 220, so that the compression stress generated by the fastener 300 near the mounting hole 213 can be more evenly transmitted to the compression plate 230 through the connecting plate 220. Furthermore, the stress release holes 223 are symmetrically arranged along the vertical center line of the connecting plate 220 to better improve the uniformity of stress transmission.

Through the above-mentioned arrangement, the stress release hole 223 can be extended roughly along the longitudinal direction of the connecting plate 220, so that there is enough release space when the stress is transmitted from the fixed plate 210 to the connecting plate 220. In one or more embodiments, the aperture of the mounting hole 213 is D, wherein L2≥D. In this way, the stress release hole 223 can have a moderate width to ensure that the stress has sufficient release space in the stress release hole 223 area, thereby effectively reducing stress concentration. In one or more embodiments, the length of the connecting plate 220 along its longitudinal direction is L, wherein 1 / 3L≤L1≤2 / 3L. In this way, the size of the stress release hole 223 can be further limited so that it has a moderate length, so as to take into account the rigidity and mechanical strength of the connecting plate 220 on the basis of satisfying stress release.

In other words, the clamping plate 230 and the fixing plate 210 extend substantially in opposite directions. In the assembled state, the clamping plate 230 abuts against the photovoltaic component 100 and applies a suitable pressure to the photovoltaic component 100, so that the photovoltaic component 100 is constrained between the clamping plate 230 and the predetermined mounting member 400, thereby quickly and firmly fixing the photovoltaic component 100. In one or more embodiments, the clamping plate 230 is an arc-shaped plate that protrudes in a direction away from the fixing plate 210. Based on Figure 3 In the orientation shown, the arc plate protrudes upward.

In one or more embodiments, an anti-skid protrusion (not shown in the figure) is formed on the pressing surface 231 of the pressing plate 230 (i.e., the surface opposite to the photovoltaic assembly 100) to further increase the friction coefficient between the pressing plate 230 and the photovoltaic assembly 100 and improve the reliability of the connection between the two. It should be pointed out that the specific shape, number and arrangement of the anti-skid protrusions can be adjusted according to actual needs.
