Description

Briquetting for photovoltaic module and photovoltaic module with briquetting

Technical Field

The utility model relates to the technical field of photovoltaics, in particular to a pressing block for a photovoltaic module and the photovoltaic module with the pressing block.

Background

Photovoltaic modules are electronic devices that utilize the photovoltaic effect to convert solar energy into electrical energy. The solar cell mainly comprises photovoltaic glass, a cell, a backboard, a fixed frame and the like. The photovoltaic module has the advantages of energy conservation, environmental protection, safety, reliability, reproducibility, long service life and the like, and is widely applied to the fields of grid-connected power generation, traffic lighting, communication base stations and the like.

Currently, when installing photovoltaic modules, a press block is generally used to fix the photovoltaic modules to a predetermined installation member (e.g., roof, shed, outdoor lamp stand, etc.). Specifically, the press block is fixed on the predetermined mount by a screw, and the press block presses the photovoltaic module such that the photovoltaic module is defined between the press block and the predetermined mount. However, the photovoltaic module can be subjected to the load actions such as wind and snow in the practical application process, so that the stress borne by the photovoltaic module is easily concentrated near the pressing block, and the parts such as photovoltaic glass are cracked or even burst, so that the safety and the service life of the photovoltaic module are greatly reduced.

Accordingly, there is a need in the art for a new solution to the above-mentioned problems.

Disclosure of utility model

In order to solve or improve the technical problem that a photovoltaic module is easy to damage due to stress concentration in the prior art to a certain extent, the utility model provides a pressing block for the photovoltaic module. The press block comprises a fixing plate, a connecting plate, a pressing plate and a pressing plate, wherein a mounting hole is formed in the fixing plate so as to fix the fixing plate on a preset mounting piece, the connecting plate is provided with a first end and a second end which are opposite, the first end is connected with the fixing plate, a stress release hole is formed in the connecting plate, the pressing plate is connected with the second end, and the pressing plate is configured to be abutted against the photovoltaic module when the fixing plate is fixed on the preset mounting piece so as to restrain the photovoltaic module between the pressing plate and the preset mounting piece.

As will be appreciated by those skilled in the art, the inventive press block includes a fixing plate, a connecting plate, and a pressing plate. Mounting holes are formed in the fixing plate to fix the fixing plate to a predetermined mounting member. The connecting plate has opposite first and second ends. The first end is connected to the fixed plate and the second end is connected to the compression plate to connect the fixed plate to the compression plate. The hold down plate is configured to rest against the photovoltaic module when the fixed plate is secured to the predetermined mount to restrain the photovoltaic module to the hold down block and the predetermined mount. Wherein, stress release holes are arranged on the connecting plate. Therefore, when the photovoltaic module is subjected to a large load, the stress at the connection part of the fixing plate and the preset mounting piece can be conducted to the connecting plate through the fixing plate, and a part of the stress is released after the stress is released through the stress release hole, so that the acting force of the pressing plate on the photovoltaic module is correspondingly reduced, the photovoltaic module is prevented from being damaged, and the safety and the service life of the photovoltaic module are improved.

In the preferable technical scheme of the pressing block for the photovoltaic module, 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 is more than or equal to L2. By the above arrangement, the stress relief holes can be made to extend substantially in the longitudinal direction of the connection plate, i.e. the stress relief holes can also be made to extend substantially in the longitudinal direction of the pressure plate. Therefore, the stress at the connection part of the fixing plate and the photovoltaic module can be effectively released when passing through the stress release hole on the connecting plate, so that the stress is ensured to have enough release space, and the stress transmitted to the compression plate is obviously reduced.

By the arrangement, the stress release holes can have moderate length, so that the rigidity and the mechanical strength of the connecting plate are both realized on the basis of meeting the stress release.

In the preferred technical scheme of the pressing block for the photovoltaic module, the stress release hole is arranged in the middle of the connecting plate. By the arrangement, stress can be more uniformly conducted to the compression plate through the connecting plate.

In the above preferred technical solution of the press block for a photovoltaic module, the stress release holes are symmetrically arranged along a vertical center line of the connecting plate, so as to further improve uniformity of stress conduction.

In the above preferred technical solution of the press block for a photovoltaic module, the stress release holes are kidney-shaped holes, triangle holes, arc holes or oval holes, so as to enrich the types of the stress release holes.

In a preferred embodiment of the above-described pressure block for a photovoltaic module, the fixing plate has a first edge and a second edge which are opposite to each other, and the connecting plate extends perpendicularly from the first edge and/or the second edge onto the pressure plate.

In a preferred embodiment of the above press block for a photovoltaic module, the press block further includes a support plate extending perpendicularly from the first edge and/or the second edge in a direction away from the connection plate, and adapted to abut against the predetermined mount. The setting of backup pad can further improve briquetting fixed photovoltaic module's reliability and stability.

In the above preferred technical solution of the press block for a photovoltaic module, the pressing plate is an arc plate protruding toward a direction away from the fixing plate. The setting of arc can make the pressure strip compress tightly photovoltaic module more firmly, prevents that photovoltaic module from slipping from the compact heap.

In the above preferred technical solution of the press block for a photovoltaic module, an anti-slip protrusion is formed on a pressing surface of the pressing plate adapted to abut against the photovoltaic module. The anti-slip convex is arranged, so that the friction coefficient between the pressing plate and the photovoltaic module can be increased, and the connection reliability of the pressing plate and the photovoltaic module is improved.

The utility model provides a photovoltaic module, which aims to solve or improve the technical problem that the photovoltaic module is easy to damage due to stress concentration in the prior art to a certain extent. The photovoltaic module comprises a briquette for a photovoltaic module according to any one of the above. By adopting the pressing block of any one of the above, the photovoltaic module can effectively avoid stress concentration, improve safety and prolong service life.

Briquette 200 may be fabricated from a suitable metal material (e.g., aluminum alloy, etc.) by a machining process (e.g., extrusion process, stamping process, etc.), resulting in good mechanical properties, weatherability, and structural stability.

With continued reference to fig. 3, in one or more embodiments, compact 200 includes a securing plate 210, a connecting plate 220, a compacting plate 230, and a supporting plate 240. The fixing plate 210 has a substantially rectangular shape. Alternatively, the fixing plate 210 may be provided in other suitable shapes, such as square, etc. In the assembled state, the fixing plate 210 extends in a substantially horizontal direction. The fixing plate 210 has two opposite edges, namely a first edge 211 and a second edge 212. Based on the orientation shown in fig. 3, the first edge 211 is the front side edge of the mounting plate 210 and the second edge 212 is the rear side edge of the mounting plate 210. In one or more embodiments, 1 mounting hole 213 is formed in the mounting plate 210. The mounting holes 213 can be mated with suitable fasteners 300 (see fig. 1 and 2) to facilitate and securely fasten the mounting plate 210 to the intended mount 400. The fastener 300 may be, but is not limited to, a bolt, a nut, a screw, etc. The mounting holes 213 may be circular holes, kidney-shaped holes, or other suitable shapes. The mounting hole 213 is disposed at a central position of the fixing plate 210 to ensure reliability of fixing. Alternatively, the mounting holes 213 may be arranged in other suitable locations. Alternatively, the mounting holes 213 may be provided in 2, 3, or other suitable numbers.

With continued reference to fig. 3, in one or more embodiments, the connection plate 220 is disposed on one of two opposing edges of the fixation plate 210. Specifically, the connection plate 220 is disposed on the second edge 212 of the fixing plate 210. Alternatively, the connection plate 220 may also be arranged on the first edge 211 of the fixing plate 210. The connection plate 220 extends generally perpendicularly along the second edge 212 of the fixation plate 210 in a direction away from the fixation plate 210 (i.e., upward based on the orientation shown in fig. 3). The connection plate 220 has opposite first 221 and second 222 ends. Wherein the first end 221 is a lower end of the connection plate 220, and the second end 222 is an upper end of the connection plate 220. The first end 221 of the connection plate 220 is connected to the fixing plate 210, and the second end 222 is connected to the pressing plate 230. The connection plate 220 has a substantially rectangular shape. Alternatively, the connection plate 220 may be provided in other suitable shapes, such as square, etc. The connection plate 220 is provided with 1 stress relief hole 223. The stress relief holes 223 may be manufactured using a suitable machining process (e.g., stamping process, drilling process, etc.). In the assembled state, the compression stress of the fastener 300 generated near the mounting hole 213 is transferred to the connection plate 220 through the fixing plate 210 and a portion is released through the stress release hole 230 disposed on the connection plate 220, thereby effectively preventing the stress from concentrating on the compression plate 230 to damage the photovoltaic module 100, and ensuring the safety and the service life of the photovoltaic module 100. In one or more embodiments, the stress relief holes 223 are disposed in the middle of the connection plate 220, which may allow compressive stress generated by the fastener 300 near the mounting hole 213 to be more uniformly conducted to the compression plate 230 through the connection plate 220. Further, the stress relief holes 223 are symmetrically arranged along the vertical center line of the connection plate 220 to better improve uniformity of stress conduction.

Fig. 4 is a front view of a first embodiment of a press block for a photovoltaic module of the present utility model. In one or more embodiments, as shown in fig. 3 and 4, the stress relief aperture 223 is a kidney-shaped aperture. Referring to fig. 4, the length of the stress relief hole 223 in the length direction of the connection plate 220 (based on the orientation shown in fig. 4, i.e., the left-right direction) is L1, and the length in the width direction of the connection plate 220 (based on the orientation shown in fig. 4, i.e., the up-down direction) is L2, where L1> L2. By the above arrangement, the stress relief holes 223 can be extended substantially along the length direction of the connection plate 220, so that there is sufficient relief space when the stress is conducted from the fixing plate 210 to the connection plate 220. In one or more embodiments, the aperture of mounting hole 213 is D, where L2 is equal to or greater than D. In this way, the stress relief holes 223 may be made to have a moderate width to ensure that the stress has sufficient relief space in the region of the stress relief holes 223, effectively reducing stress concentrations. In one or more embodiments, the length of the web 220 along its length is L, where 1/3 L.ltoreq.L1.ltoreq.2/3L. In this way, the stress relief holes 223 may be further sized to have a moderate length to compromise the rigidity and mechanical strength of the connection plate 220 on the basis of satisfying the stress relief.

With continued reference to fig. 3, in one or more embodiments, the compression plate 230 is disposed on a side of the connection plate 220 that is remote from the fixation plate 210. Specifically, based on the orientation shown in fig. 3, the fixing plate 210 is disposed at the front side of the connection plate 220, and the pressing plate 230 is disposed at the rear side of the connection plate 220. The compacting plate 230 is configured such that the second end 222 of the connecting plate 220 extends away from the fixing plate 210. In other words, the pressing plate 230 and the fixing plate 210 extend substantially in opposite directions. In the assembled state, the compression plate 230 abuts against the photovoltaic module 100 and applies a suitable pressure to the photovoltaic module 100 such that the photovoltaic module 100 is restrained between the compression plate 230 and the predetermined mount 400, thereby rapidly and firmly fixing the photovoltaic module 100. In one or more embodiments, the compression plate 230 is an arcuate plate that protrudes away from the fixed plate 210. Based on the orientation shown in fig. 3, the arcuate plate is upwardly convex. The arrangement of the arc plate can more firmly restrain the photovoltaic module 100 and prevent the photovoltaic module 100 from slipping off the pressing plate 230. In one or more embodiments, a non-slip protrusion (not shown) is formed on the pressing surface 231 of the pressing plate 230 (i.e., the surface opposite to the photovoltaic module 100) to further increase the friction coefficient between the pressing plate 230 and the photovoltaic module 100 and to increase the reliability of the connection therebetween. It should be noted that the specific shape, number and arrangement of the cleats may be adjusted according to actual needs.

With continued reference to fig. 3, in one or more embodiments, the support plate 240 is disposed on one of two opposing edges of the fixation plate 210. Specifically, the support plate 240 is disposed on the first edge 211 of the fixing plate 210. Alternatively, the support plate 240 may also be disposed on the second edge 212 of the fixing plate 210. The support plate 240 is configured to extend from the first edge 211 of the fixing plate 210 substantially perpendicularly toward a direction away from the connection plate 220. Based on the orientation shown in fig. 3, the support plate 240 extends generally vertically downward from the front side edge of the fixed plate 210. In the assembled state, the support plate 240 may abut against the predetermined mount 400 to improve the stability of the connection of the press block 200, the photovoltaic module 100, and the predetermined mount 400. In one or more embodiments, a support seat 241 is provided at the bottom of the support plate 240 to increase the contact area between the support plate 240 and the predetermined mount 400, thereby improving the support effect.
