Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power station supporting technology, and in particular to a grounding pad used between photovoltaic modules and crossbeams. Background Technology

[0002] During the construction of photovoltaic power plants, grounding pads are typically installed between the photovoltaic modules and supporting beams to ensure safe grounding and stable installation of the modules. Currently, most existing photovoltaic module grounding pads include a supporting base plate with positioning holes for positioning the pads with the modules and beams. Some pads have anti-slip rubber blocks at the bottom to improve stability after installation, while the top is equipped with basic buffer components (such as simple rubber blocks) to mitigate the impact of environmental vibrations (such as wind or equipment operation) during photovoltaic module operation. Simultaneously, to meet limiting requirements, some grounding pads are designed with a single limiting area, and most pads are manufactured using conventional molding processes, with components assembled using bolts and other connectors. This allows them to basically achieve grounding conductivity, basic buffering, and anti-slip positioning functions, and they have certain applications in current small and medium-sized photovoltaic power plants and low-load operation scenarios.

[0003] However, existing photovoltaic module grounding pads still have many limitations in practical applications. Regarding buffering performance, existing pads lack a multi-directional pressure decomposition structure and do not have centrally distributed buffer support grooves, failing to effectively decompose vertical pressure into multi-directional components. This results in a short buffering time and susceptibility to cracking and damage due to localized stress concentration. In terms of load-bearing capacity, the design of the stress-bearing area of ​​existing pads is unreasonable, often with only one limiting area, leading to an unbalanced stress structure that cannot meet the load-bearing requirements of large photovoltaic modules during long-term operation. In terms of structure and manufacturing process, existing pads mostly use non-integrated molding processes, and the assembled structure has not undergone mechanical simulation optimization, making it difficult to achieve lightweight design while ensuring structural strength. Regarding maintenance convenience, the connection methods of existing pad components are complex. When components wear out and need replacement, it is often necessary to destroy the entire structure for disassembly, resulting in cumbersome and costly maintenance operations, failing to meet the current needs of efficient operation and maintenance and long-term stable operation of photovoltaic power plants. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a grounding pad for use between photovoltaic modules and crossbeams, which solves the problems of poor buffering, weak load-bearing capacity, non-integration, and high maintenance costs of existing photovoltaic grounding pads.

[0005] This utility model is achieved using the following technical solution: a grounding pad for photovoltaic modules and crossbeams, comprising a bearing base plate, wherein a positioning hole is provided inside the bearing base plate, an anti-slip rubber block one is fixedly connected to the bottom of the bearing base plate, an anti-slip rubber block two is fixedly connected to the bottom of the bearing base plate, a buffer grounding block is fixedly connected to the top of the bearing base plate, a secondary limiting zone is provided inside the buffer grounding block, and a buffer support groove is provided on the surface of the buffer grounding block.

[0006] Through the above technical solution, the anti-slip rubber block one and anti-slip rubber block two, which are synchronously fixed at the bottom of the supporting base plate, form a dual anti-slip system. The two sets of anti-slip rubber blocks act on different contact surfaces, which can not only enhance the initial static friction with the metal surface of the photovoltaic panel, but also compensate for surface wear after long-term use through elastic deformation, and continuously maintain a stable anti-slip effect, effectively suppressing the risk of slippage caused by temperature changes or humid environments.

[0007] As a further improvement to the above solution, the number of positioning holes is set to four, and two holes are grouped together, with the four positioning holes symmetrically distributed around the supporting base plate.

[0008] As a further improvement to the above solution, the number of the positioning holes and anti-slip rubber blocks is set to two, and the two positioning holes and anti-slip rubber blocks are symmetrically distributed with the supporting base plate as the center.

[0009] Through the above technical solution, the four positioning holes arranged symmetrically inside the bearing base plate provide a reliable installation reference for the shock absorber, effectively offsetting the lateral impact force during vehicle operation and preventing the shock absorber from shifting or loosening due to vibration. It is especially suitable for high-frequency vibration scenarios under complex road conditions, ensuring that the photovoltaic system is always in the preset working position.

[0010] As a further improvement to the above scheme, the number of the secondary limiting zones is set to two, and the two secondary limiting zones are symmetrically distributed with the buffer grounding block as the center.

[0011] Through the above technical solution, two centrally symmetrical secondary limiting zones are opened inside the buffer grounding block to construct a stepped buffer structure. When subjected to severe impact, the primary deformation is absorbed by the rubber body to absorb most of the kinetic energy, while the secondary limiting zone acts as a rigid constraint boundary to prevent permanent deformation or failure caused by excessive compression of the rubber, thus balancing comfort and durability.

[0012] As a further improvement to the above scheme, the secondary limiting zone is located at the bottom of the bearing base plate, and the number of buffer support grooves is set to several, with the several buffer support grooves being equidistantly distributed around the buffer grounding block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention decomposes vertical pressure into multi-directional components by setting several buffer support grooves evenly distributed around the center on the surface of the buffer grounding block. This not only expands the effective pressure-bearing area but also extends the buffer time through the deformation hysteresis effect of the groove wall, allowing the impact force to dissipate gradually and significantly reducing the risk of cracking caused by local stress concentration. By setting the overall equipment, the area of ​​the stress-bearing zone is increased, improving the load-bearing capacity of the limiting block. The secondary limiting zone is increased from one to two, improving the stress-bearing structure.

[0015] This utility model adopts an integrated molding process for the bearing base plate, buffer ground block and various functional accessories. The spatial layout of the secondary limit zone and buffer support groove has been optimized through mechanical simulation. It achieves lightweight design while ensuring structural strength. If worn parts need to be replaced, the bearing base plate and rubber block can be quickly separated by simply removing the bolts without damaging the overall structure, thus reducing the later maintenance cost.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Please combine Figures 1-4This embodiment provides a grounding pad for use between a photovoltaic module and a crossbeam, comprising a supporting base plate 1, a positioning hole 2 inside the supporting base plate 1, an anti-slip rubber block 3 fixedly connected to the bottom of the supporting base plate 1, an anti-slip rubber block 4 fixedly connected to the bottom of the supporting base plate 1, a buffer grounding block 5 fixedly connected to the top of the supporting base plate 1, a secondary limiting zone 6 inside the buffer grounding block 5, and a buffer support groove 7 on the surface of the buffer grounding block 5. By setting several buffer support grooves 7 evenly distributed around the center on the surface of the buffer grounding block 5, the vertical pressure is decomposed into multi-directional components, which not only expands the effective bearing area, but also extends the buffer time through the deformation hysteresis effect of the groove wall, allowing the impact force to dissipate gradually, greatly reducing the risk of cracking caused by local stress concentration. By setting the overall equipment, the area of ​​the stress zone is increased, the bearing capacity of the limiting block is improved, and the secondary limiting zone 6 is increased from one to two, improving the stress structure.

[0024] The anti-slip rubber block 3 and anti-slip rubber block 4, which are fixed synchronously at the bottom of the supporting base plate 1, form a dual anti-slip system. The two sets of anti-slip rubber blocks act on different contact surfaces, which can enhance the initial static friction with the metal surface of the photovoltaic panel, and compensate for surface wear after long-term use through elastic deformation, thus maintaining a stable anti-slip effect and effectively suppressing the risk of slippage caused by temperature changes or humid environments.

[0025] The number of positioning holes 2 is set to four, and each pair is a group of two. The four positioning holes 2 are symmetrically distributed with the supporting base plate 1 as the center.

[0026] The number of positioning holes 2 and anti-slip rubber blocks 3 is set to two, and the two positioning holes 2 and anti-slip rubber blocks 3 are symmetrically distributed with the bearing base plate 1 as the center.

[0027] The four centrally symmetrically distributed positioning holes 2 inside the bearing base plate 1 provide a reliable installation reference for the shock absorber, effectively offsetting the lateral impact force during vehicle operation and preventing the shock absorber from shifting or loosening due to vibration. It is especially suitable for high-frequency vibration scenarios with strong winds, ensuring that the photovoltaic system is always in the preset working position.

[0028] The number of secondary limit zones 6 is set to two, and the two secondary limit zones 6 are symmetrically distributed with the buffer grounding block 5 as the center. By setting the bearing base plate 1, the buffer grounding block 5 and all functional accessories to adopt the integrated molding process, the spatial layout of the secondary limit zones 6 and the buffer support groove 7 has been optimized by mechanical simulation. The lightweight design has been achieved while ensuring the structural strength. If it is necessary to replace worn parts, the bearing base plate 1 and the rubber block can be quickly separated by simply removing the bolts without damaging the overall structure, which reduces the later maintenance cost.

[0029] The buffer grounding block 5 has two centrally symmetrical secondary limiting zones 6 inside, which form a stepped buffer structure. When subjected to severe impact, the primary deformation is absorbed by the rubber body, which absorbs most of the kinetic energy. The secondary limiting zone 6 acts as a rigid constraint boundary to prevent permanent deformation or failure caused by excessive compression of the rubber, thus balancing comfort and durability.

[0030] The secondary limiting zone 6 is located at the bottom of the bearing base plate 1, and the number of buffer support grooves 7 is set to several, with the several buffer support grooves 7 being equidistantly distributed around the buffer grounding block 5.

[0031] The implementation principle of a grounding pad for photovoltaic modules and crossbeams in this embodiment is as follows: By setting several buffer support grooves 7 evenly distributed around the center on the surface of the buffer grounding block 5, the vertical pressure is decomposed into multi-directional components. This not only expands the effective bearing area but also extends the buffer time through the deformation hysteresis effect of the groove wall, allowing the impact force to dissipate gradually and significantly reducing the risk of cracking caused by local stress concentration. By setting the overall equipment, the area of ​​the stress zone is increased, improving the bearing capacity of the limiting block. The secondary limiting zone 6 is increased from one to two, improving the stress structure. By setting the bearing base plate 1, buffer grounding block 5, and various functional accessories to adopt an integrated molding process, the spatial layout of the secondary limiting zone 6 and buffer support grooves 7 is optimized through mechanical simulation. Lightweight design is achieved while ensuring structural strength. If worn parts need to be replaced, the bearing base plate 1 and rubber block can be quickly separated by removing the bolts without damaging the overall structure, reducing the later maintenance cost.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
