Description

Technical Field

[0001] This utility model belongs to the field of wire clamp technology, and specifically relates to a photovoltaic wire clamp. Background Technology

[0002] Utility model patent CN222016495U discloses a photovoltaic wire clamp, a photovoltaic wire clamp for frameless photovoltaic modules, comprising two elastic clamping devices, each clamping device being S-shaped and connected together. Each clamping device includes an upper clamping portion that abuts against the upper surface of the frameless photovoltaic module and a lower clamping portion that abuts against the lower surface of the frameless photovoltaic module. The lower clamping portion is connected to at least one first support portion for supporting the wire. Further, a second support portion for supporting the wire is connected between the first support portions of the two clamping devices. This utility model has a reasonable structural design; the two S-shaped clamping devices can clamp onto the frameless photovoltaic module, and the two S-shaped clamping devices have strong clamping force, are stable and reliable, and have good strength. The wire can be supported using either the first or second support portion without abrading the wire.

[0003] However, the aforementioned mechanism has the following problems: Since the photovoltaic clamp is formed by bending a thin wire, the contact area between the upper clamping part that abuts against the upper surface of the frameless photovoltaic module and the lower clamping part that abuts against the lower surface of the frameless photovoltaic module is small. This affects the stability of the photovoltaic clamp on the photovoltaic panel (the small contact area leads to low friction and poor anti-slip performance), and may wear down the surface coating of the photovoltaic panel during installation and use (the small contact area and rigid contact make the surface coating of the photovoltaic panel easily damaged). In addition, since the photovoltaic panel is used outdoors, it will be subjected to slight vibrations from factors such as wind and rain, which will cause repeated friction and sliding between the photovoltaic panel and the photovoltaic clamp, further affecting the stability of the photovoltaic clamp on the photovoltaic panel and the friction wear of the photovoltaic panel surface. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a photovoltaic wire clamp that solves the problems of existing photovoltaic wire clamps being prone to damage to the photovoltaic panel coating due to their small contact area at the clamping end, and having a simple buffer structure that is difficult to resist vibration, leading to detachment and displacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic wire clamp, comprising a wire clamp body and a buffer component. The wire clamp body includes a middle section, both ends of which are bent into wire support sections. One end of the wire support section is bent into a lower connecting section. One end of the lower connecting section is bent into a lower pressing section in a direction parallel to and away from the middle section. One end of the lower pressing section is folded back towards the middle section to form a lower deformable section. One end of the lower deformable section is bent into an upper connecting section in a direction parallel to and away from the lower connecting section. One end of the upper connecting section is folded back to form an upper deformable section. One end of the upper deformable section is inclined towards the lower deformable section, and one end of the upper deformable section is bent into an upper pressing section in a direction parallel to the lower pressing section. The buffer component is fitted onto the outside of the upper and lower pressing sections.

[0006] The beneficial effects of this utility model are as follows: the lateral bending design of the upper and lower pressing sections can effectively increase the contact area between the wire clamp body and the photovoltaic cell, avoid excessive pressure on the local coating of the photovoltaic panel and damage, and the buffer component works with it to further protect the photovoltaic panel. Through its own elastic buffer and surface friction resistance, it can effectively prevent the wire clamp body from falling off the photovoltaic panel when it shakes slightly.

[0007] To ensure the positional stability of the buffer component on the lower pressing section;

[0008] As a further improvement to the above technical solution: the length of the buffer piece fitted on the outer side of the pressing segment is the same as the length of the pressing segment.

[0009] The beneficial effects of this improvement are: the buffer is limited in the axial direction by the lower deformation section and the lower connecting section on both sides of the lower pressing section, thereby preventing it from shaking on the lower pressing section and affecting the stability of the wire clamp body on the photovoltaic panel.

[0010] To ensure the positional stability of the buffer component on the upper pressing section;

[0011] As a further improvement to the above technical solution: one end of the upper pressing section is bent into an anti-detachment section, and the length of the buffer piece fitted on the outer side of the upper pressing section is the same as the length of the upper pressing section.

[0012] The beneficial effects of this improvement are: the buffer is limited in the axial direction by the upper deformation section and the anti-detachment section on both sides of the lower pressing section, thereby preventing it from shaking on the upper pressing section and affecting the stability of the wire clamp body on the photovoltaic panel.

[0013] To facilitate the installation and fixing of the wire clamp body on the photovoltaic panel;

[0014] As a further improvement to the above technical solution: one end of the anti-detachment section is inclined away from the downward pressing section.

[0015] The beneficial effect of this improvement is that the height of the slot formed between the anti-detachment section and the lower pressure section for clamping onto the photovoltaic panel gradually decreases, which facilitates the installation of the wire clamp body on the photovoltaic panel.

[0016] To facilitate the installation and fixation of the buffer component on the wire clamp body;

[0017] As a further improvement to the above technical solution: the buffer component is in the form of a sleeve structure, and the buffer component has a slot that runs through the front and rear ends and the inner and outer sides of the buffer component.

[0018] The beneficial effects of this improvement are: the buffer itself has a good elastic deformation capacity, it can be pried open at the slot and fitted on the outside of the upper and lower pressing sections, and then elastically reset to form a sleeve structure, and the structural stability of the buffer is ensured by applying glue at the slot.

[0019] To prevent the buffer from rolling on the photovoltaic panel;

[0020] As a further improvement to the above technical solution: the buffer component is composed of an integrally formed support layer, a sleeve layer and a buffer layer. The buffer layer connects the outer wall of the sleeve layer and the inner wall of the support layer. The sleeve layer is adapted to be installed on the outside of the upper pressing section and the lower pressing section. The support layer has a regular prism structure.

[0021] The beneficial effects of this improvement are: compared with the circular tube structure, the prism structure of the support layer can effectively prevent itself from rolling on the photovoltaic panel surface, thereby affecting the stability of the wire clamp body on the photovoltaic panel.

[0022] In order to effectively ensure the cushioning and shock absorption performance of the buffer components;

[0023] As a further improvement to the above technical solution: the buffer layer is an arc-shaped plate structure, the number of buffer layers is multiple and they are evenly arranged around the axis of the sleeve layer, the two ends of the buffer layer are connected to the inner wall of the support layer, and the middle of the buffer layer is connected to the sleeve layer.

[0024] The beneficial effects of this improvement are as follows: when the photovoltaic panel experiences minor vibrations due to wind or other reasons, the support layer transfers the vibration potential energy to the buffer layer, causing the buffer layer to undergo elastic deformation, thereby absorbing and buffering the vibration potential energy and preventing the main body of the wire clamp from sliding or even falling off the photovoltaic panel.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0031] Example 1:

[0032] like Figure 1—3 shows: A photovoltaic wire clamp, including a wire clamp body 1 and a buffer 2. The wire clamp body 1 includes a middle section 11. Both ends of the middle section 11 are bent into wire support sections 10. One end of the wire support section 10 is bent into a lower connecting section 9. One end of the lower connecting section 9 is bent into a lower pressing section 8 in a direction parallel to and away from the middle section 11. One end of the lower pressing section 8 is folded back into a lower deformable section 7 in the direction of the middle section 11. One end of the lower deformable section 7 is bent into an upper connecting section 3 in a direction parallel to and away from the lower connecting section 9. One end of the upper connecting section 3 is folded back into an upper deformable section 4. One end of the upper deformable section 4 is inclined towards the lower deformable section 7, and the upper deformable section... One end of segment 4 is bent into an upper pressing segment 5 in a direction parallel to the lower pressing segment 8. The buffer 2 is fitted onto the outside of the upper pressing segment 5 and the lower pressing segment 8. The lateral bending design of the upper pressing segment 5 and the lower pressing segment 8 can effectively increase the contact area between the wire clamp body 1 and the photovoltaic cell, avoiding excessive pressure on the local coating of the photovoltaic panel and damage. The buffer 2 works with it to further protect the photovoltaic panel, and through its own elastic buffer and surface friction resistance, it effectively prevents the wire clamp body 1 from falling off when the photovoltaic panel shakes slightly. The length of the buffer 2 fitted onto the outside of the lower pressing segment 8 is the same as the length of the lower pressing segment 8. The buffer 2 is limited in the axial direction by the lower deformable segment 7 and the lower connecting segment 9 on both sides of the lower pressing segment 8, thereby preventing... To prevent the wire clamp body 1 from wobbling on the lower pressing section 8 and affecting its stability on the photovoltaic panel, one end of the upper pressing section 5 is bent into an anti-detachment section 6. The buffer 2, which is fitted on the outside of the upper pressing section 5, has the same length as the upper pressing section 5. The buffer 2 is limited in the axial direction by the upper deformation section 4 on both sides of the lower pressing section 8 and the anti-detachment section 6, thereby preventing it from wobbling on the upper pressing section 5 and affecting the stability of the wire clamp body 1 on the photovoltaic panel. One end of the anti-detachment section 6 is inclined away from the lower pressing section 8. The height of the slot formed between the anti-detachment section 6 and the lower pressing section 8 for mounting on the photovoltaic panel is gradually tapering, facilitating the installation of the wire clamp body 1 on the photovoltaic panel. The buffer 2 has an overall sleeve structure. The buffer component 2 has slots extending through its front and rear ends and its inner and outer sides. The buffer component 2 itself has good elastic deformation capacity, allowing it to be pried open at the slots and fitted onto the outer sides of the upper pressing section 5 and the lower pressing section 8. It then elastically returns to its original sleeve structure. The structural stability of the buffer component 2 is ensured by applying adhesive to the slots. The buffer component 2 is composed of an integrally formed support layer 21, a sleeve layer 22, and a buffer layer 23. The buffer layer 23 connects the outer wall of the sleeve layer 22 and the inner wall of the support layer 21. The sleeve layer 22 is adapted to fit onto the outer sides of the upper pressing section 5 and the lower pressing section 8. The support layer 21 has a regular prism structure. Compared to a circular tube structure, the regular prism structure of the support layer 21 effectively prevents it from rolling on the photovoltaic panel surface.This affects the stability of the wire clamp body 1 clamping on the photovoltaic panel. The buffer layer 23 has an arc-shaped plate structure. Multiple buffer layers 23 are evenly arranged around the axis of the sleeve layer 22. The two ends of the buffer layer 23 are connected to the inner wall of the support layer 21, and the middle of the buffer layer 23 is connected to the sleeve layer 22. When the photovoltaic panel experiences minor vibrations due to wind or other reasons, the support layer 21 transfers the vibration potential energy to the buffer layer 23, causing the buffer layer 23 to undergo elastic deformation. This absorbs and buffers the vibration potential energy, preventing the wire clamp body 1 from sliding or even falling off the photovoltaic panel.

[0033] The working principle of this technical solution is as follows: The operator aligns the groove between the upper crimping section 5 and the lower crimping section 8 with the installation edge of the photovoltaic panel. Because the anti-detachment section 6 is inclined away from the lower crimping section 8, the groove is in a "gradually narrowing state," which can easily guide the edge of the photovoltaic panel into the groove. The operator slowly presses the upper connecting section 3 towards the photovoltaic panel, and uses the elastic deformation of the upper deformation section 4 and the lower deformation section 7 to gradually clamp the photovoltaic panel between the upper crimping section 5 and the lower crimping section 8. During the pressing process, it is necessary to ensure that the buffer 2 of the upper crimping section 5 and the lower crimping section 8 is completely in contact with the surface of the photovoltaic panel. Because the crimping section is a horizontally bent design, the contact area is large, which reduces the local pressure and effectively protects the coating. At this time, the wire clamp body 1 is kept in a clamped state by the elastic force of the upper and lower deformation sections, and the anti-detachment section 6 is in contact with the edge of the photovoltaic panel to prevent the wire clamp from slipping horizontally. The cable is placed in the area between the two wire support sections 10 and the lower deformation section 7, so that it bears and restricts the position of the cable.

[0034] When the photovoltaic panel experiences minor vibrations due to wind or temperature changes, the arc-shaped buffer layer 23 of the buffer component 2 comes into play. The support layer 21 transmits the vibration potential energy to the multiple arc-shaped buffer layers 23 distributed around it. The buffer layer 23 absorbs the potential energy through its own elastic deformation, achieving vibration attenuation and preventing the vibration from being directly transmitted to the main body of the wire clamp 1, which could cause loosening. At the same time, the support layer 21 adopts a regular prism structure, which significantly increases the frictional resistance with the surface of the photovoltaic panel compared to traditional round tube buffer components, and eliminates the risk of rolling. The elastic deformation of the buffer component itself ensures that the support layer 21 is always in close contact with the surface of the photovoltaic panel. Even if the photovoltaic panel shifts slightly, the frictional force can counteract the sliding tendency and prevent the wire clamp from shifting or falling off.
