Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel cables, and in particular to a photovoltaic panel cable fixing and installation structure. Background Art

[0002] As the global demand for clean energy continues to increase, photovoltaic power generation has developed rapidly as a sustainable way to obtain energy. Photovoltaic panels need to transmit the generated electricity to inverters, distribution boxes and other equipment through cables, which has prompted the advancement of photovoltaic panel cable technology. In large-scale photovoltaic power stations, there may be tens of thousands of photovoltaic panels, and an efficient and safe cable transmission system is essential.

[0003] For the current fixed installation structure, the existing photovoltaic panel cable fixed installation structure disclosed by patent number "CN117937344B" is that during the cable laying process, the guide roller is lifted so that the cable can be placed on the guide roller to reduce the resistance of cable dragging. After the cable is laid, the guide roller is lowered so that the cable falls into the groove of the bracket, and the clamping arms on both sides clamp the cable in the middle. This device fixes the cable through the installation bracket, but the spacing of each installation bracket is fixed. When adjustment is required and the gap between cables cannot be adjusted, a temporary measure of skipping the middle part of the installation bracket is taken. Although the change of the spacing is achieved to a certain extent, the installation bracket that should be reasonably used is left idle, resulting in serious idleness and waste of material resources. Based on this, the present application proposes an invention content, a photovoltaic panel cable fixed installation structure. Summary of the invention

DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1

[0054] Reference Figure 1 , Figure 2 , Figure 3 ,and Figure 5 A photovoltaic panel cable fixing and installation structure includes a base 1, a slide rail 2 is arranged on the base 1, and a plurality of mounting seats 3 are slidably connected to the slide rail 2. The plurality of mounting seats 3 are arranged in a hollow shape, and the inner walls of the plurality of mounting seats 3 are all provided with annular grooves 32. The inner wall of the annular groove 32 is slidably connected with a convex rod 63, and the end of the convex rod 63 away from the annular groove 32 is fixedly connected with a slider 6, so that the slider 6 can stably move up and down under the restriction of the annular groove 32, thereby ensuring the accuracy and reliability of its motion trajectory.

[0055] A connecting block 61 is fixedly connected to the bottom of the slider 6, a cam 62 is rotatably connected to the middle of the connecting block 61, a sliding rod 7 is slidably connected to the side wall of the mounting seat 3, sliding grooves 31 are symmetrically provided on both sides of the mounting seat 3, a cross bar 8 is slidably connected to the inner wall of the sliding groove 31, supporting blocks 11 are fixedly connected to the opposite sides of the mounting seat 3, a supporting rod 12 is rotatably connected to the middle of the supporting block 11, a fixing seat 13 is fixedly connected to the supporting rod 12, and the front and rear ends of the fixing seat 13 are arranged in an arc surface, which can reduce the friction and scratching between the cable and the end of the fixing seat 13, and avoid damage to the cable sheath during operation.

[0056] The fixed seat 13 is fixedly connected with a cross plate 14 on two opposite sides, and also includes a fixing component, a limit component, a driving component, a rotating component and a clamping component. The fixing component is used to fix the mounting seat 3 on the slide rail 2. The fixing component includes an insert rod 4, a screw rod 41 and a nut 42. The insert rod 4 is inserted into the mounting seat 3, the screw rod 41 is fixedly connected to the side end of the insert rod 4, the screw rod 41 is slidably connected to the mounting seat 3, and the nut 42 is threadedly connected to the screw rod 41.

[0057] A sliding plate 5 is slidably sleeved on the insertion rod 4, and a push rod 51 is fixedly connected to the inner side wall of the sliding plate 5. A socket that fits with the push rod 51 is provided on the side wall of the mounting seat 3. A cam groove 52 is provided on the push rod 51, and a cam 62 is slidably connected to the cam groove 52. The front end of the push rod 51 is arranged in an inclined surface, which can make the contact process between the push rod 51 and the cam 62 smoother and more gradual. At the same time, the cam groove 52 is closely matched with the outer contour of the cam 62. When the cam 62 starts to rotate due to the force of the push rod 51, the edge of the cam 62 always keeps in contact with the inner wall of the cam groove 52.

[0058] Through holes are provided on the base 1, the slide rail 2 and the mounting seat 3 for easy insertion of the insertion rod 4. The diameter of the insertion rod 4 matches the diameter of the through hole, ensuring that the insertion rod 4 can fit tightly after being inserted into the through hole. The mounting seat 3 will not shake due to excessive gap, nor will it be difficult to operate due to too tight insertion.

[0059] In this embodiment, when adjusting the position of the mounting seat 3 on the slide rail 2 according to the spacing between the cables, the nut 42 is first unscrewed from the screw 41. At this time, the insertion rod 4 is pulled out from the corresponding through holes on the base 1, the slide rail 2 and the mounting seat 3, and after sliding the mounting seat 3 to a suitable position, the sliding plate 5 is put on the insertion rod 4, and then the insertion rod 4 and the screw 41 are reinserted into the through hole. The sliding plate 5 enters the interior of the mounting seat 3 through the insertion hole driven by the insertion rod 4, and then the nut 42 is screwed into the screw 41, so that the insertion rod 4 limits the mounting seat 3 to prevent the mounting seat 3 from sliding during the installation process, and the cable is fixedly installed through the driving assembly, the rotating assembly and the clamping assembly. Embodiment 2

[0060] Different from the first embodiment, Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 When the locking cam 72 is in the action state, the locking cam 72 is locked and the locking cam 73 is in the action state of locking the locking cam 74. When the locking cam 72 is in the action state, the locking cam 72 is locked and the locking cam 73 is in the action state of locking the locking cam 74.

[0061] The driving assembly is used to drive the cross bar 8 to move up and down. The driving assembly is symmetrically arranged about the axis of the slider 6. The driving assembly includes a rotating shaft 81, a first gear 82, a first rack 83 and a second rack 84. The rotating shaft 81 is rotatably connected to the inner wall of the mounting base 3, the first gear 82 is fixedly connected to the rotating shaft 81, and the first rack 83 is slidably connected to the inner wall of the slide groove 31. The inner wall of the slide groove 31 is provided with a groove with the first rack 83, which can ensure that the first rack 83 moves along a predetermined straight line trajectory.

[0062] The first rack 83 is fixedly connected to the cross bar 8 , the first gear 82 and the first rack 83 are meshed with each other, the second rack 84 is fixedly connected to the side wall of the slider 6 , and the first gear 82 and the second rack 84 are meshed with each other.

[0063] One end of the cross bar 8 away from the slide slot 31 is fixedly connected to a support plate 9, and the top of the support plate 9 is fixedly connected to a wire reel seat 10, which can reduce the dragging resistance of the cable, protect the outer skin of the cable, and extend the service life of the cable.

[0064] In this embodiment, after the position of the mounting seat 3 is determined, the cable is laid immediately, and the cable is placed on the wire reel seat 10 to start the laying operation. During this process, the limit block 72 is tightly stuck in the limit groove 71, thereby limiting the displacement of the slider 6, effectively preventing the wire reel seat 10 from accidentally moving downward due to the cable's own weight or other external factors.

[0065] After the cable laying is completed, the insertion rod 4 and the screw rod 41 are completely inserted into the through holes of the base 1 and the mounting seat 3, and the sliding plate 5 and the push rod 51 are pushed to move smoothly forward. When the push rod 51 contacts the cam 62, the cam 62 is forced to drive the slider 6 to move upward. At this time, the first racks 83 on both sides of the slider 6 are engaged with the first gear 82. As the slider 6 moves upward, the first gear 82 is forced to start rotating. At the same time, the second rack 84 is driven to move downward, and the cross bar 8 closely connected to the side wall of the second rack 84 moves smoothly downward along the slide groove 31, and finally drives the wire wheel seat 10 to move smoothly down to the specified positions on both sides of the mounting seat 3.

[0066] During the upward movement of the slider 6, the limit block 72 will continue to be squeezed backward, thereby driving the slide rod 7 to move backward. When the slider 6 moves to a certain position and the limit block 72 contacts with the limit groove 71 again, under the elastic restoring force of the spring 73, the limit block 72 is reset and firmly inserted into the limit groove 71, thereby effectively preventing the slider 6 from accidentally moving downward due to external accidental factors, thereby ensuring the fixed state after the cable is laid. Embodiment 3

[0067] Reference Figure 2 , Figure 3 , Figure 6 and Figure 8 Compared with the first embodiment and the second embodiment, the rotating assembly in this embodiment is used to adjust the angle of the fixed seat 13. The rotating assembly includes a second gear 1201 and a third rack 1202. The second gear 1201 is fixedly connected to the end of the support rod 12, and the third rack 1202 is fixedly connected to the inner side wall of the wire wheel seat 10. The second gear 1201 and the third rack 1202 are meshed with each other. The second gear 1201 and the third rack 1202 are arranged in the same horizontal plane. When the wire wheel seat 10 is at the side wall position of the mounting seat, the third rack 1202 and the second gear 1201 maintain a secure connection. When the wire wheel seat 10 starts to move downward, the third rack 1202 is driven to gradually approach the second gear 1201 and contact it, so that the second gear 1201 starts to rotate under the action of the third rack 1202 and drives the fixed seat 13 to rotate. When the wire wheel seat 10 is completely moved down to the predetermined position, the top of the third rack 1202 is just in meshing state with the second gear 1201, and the slider 6 and the wire wheel seat 10 are limited by the limiting component to prevent the third rack 1202 from driving the second gear 1201 to rotate again due to unexpected circumstances.

[0068] The clamping assembly is used to clamp the photovoltaic panel cable, and the clamping assembly includes a double-headed screw 1401, a rotating handle 1402, an L-shaped block 1403 and a clamping ring 1404. The double-headed screw 1401 is rotatably connected to the inner wall of the cross plate 14, the rotating handle 1402 is fixedly connected to the top of the double-headed screw 1401, the L-shaped block 1403 is threadedly connected to the threaded section of the double-headed screw 1401, and the clamping ring 1404 is fixedly connected to the side wall of the L-shaped block 1403. The inner wall of the clamping ring 1404 is installed with an anti-slip pad, which can provide sufficient friction to prevent the cable from sliding and avoid scratching or damage to the cable sheath.

[0069] In this embodiment, the double-headed screw 1401 is driven to rotate by rotating the handle 1402, and the L-shaped block 1403 sleeved on the outside thereof drives the clamping ring 1404 to clamp the cable on the fixing seat 13 to prevent loosening or displacement due to external factors. When the wire wheel seat moves downward, the third rack 1202 of the side wall is driven to engage with the second gear 1201, and the second gear 1201 is rotated by force and drives the support rod 12 to rotate, thereby adjusting the angle of the fixing seat 13 to make it inclined, avoiding the problem of possible water accumulation, and effectively preventing the cable skin from being damaged due to water accumulation.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
