Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable laying technology, and in particular to a guiding device for laying photovoltaic cables. Background Technology

[0002] The primary function of photovoltaic cables is to transmit the electrical energy generated by solar panels, ensuring the overall stability and efficiency of the entire solar energy system. Photovoltaic cable laying equipment is a specialized device for laying photovoltaic cables, which can lay the cables at the corresponding locations on the ground.

[0003] In related technologies, photovoltaic cable laying guide devices are key auxiliary equipment in the construction of photovoltaic power plants. They are mainly used to accurately guide the cable's path, reduce friction damage, and improve construction efficiency. The guide device mainly consists of four parts: a guide frame, guide wheels, an adjustment mechanism, and a support base. These components work together to achieve stable cable guidance. Existing photovoltaic cables have a wide diameter range, but most guide devices have fixed wheel spacing or limited adjustment range, making it difficult to adapt to cables of different diameters. For example, small-diameter cables are prone to wobbling and shifting in wide-spacing wheels, while large-diameter cables may be squeezed due to excessively narrow spacing, leading to insulation damage. Furthermore, because the wheel angle is fixed, it cannot adapt to complex laying paths; forcing it through can easily cause excessive cable bending, affecting its service life.

[0022] In one embodiment, such as Figure 1 and Figure 2 As shown, a photovoltaic cable laying guide device 10 includes: a support base 100, a guide frame 200, a horizontal wheel assembly 300, and a vertical wheel assembly 400; the guide frame 200 is fixed to the upper surface of the support base 100, and a first guide rail is provided on each of the two vertical sidewalls of the guide frame 200; a lower fixing plate 220 and an upper fixing plate 210 are respectively provided on the bottom and top surfaces inside the guide frame 200, and a second guide rail is provided on the lower end surface of the upper fixing plate 210 and the upper end surface of the lower fixing plate 220; the horizontal wheel assembly 300 includes an upper guide wheel 320 and a lower guide wheel 310, and the two ends of the upper guide wheel 320 and the lower guide wheel 310 are respectively... The upper guide wheel 320 is slidably connected to the first guide rail, and the upper guide wheel 320 is provided with a spring 330. The upper end of the spring 330 is fixedly connected to the top of the guide frame 200. The vertical wheel assembly 400 includes a left guide wheel 410 and a right guide wheel 420. The upper and lower ends of the left guide wheel 410 and the right guide wheel 420 are respectively slidably connected to the second guide rail. The bottom and top surfaces inside the guide frame 200 are provided with arc grooves 240. The upper end of the upper fixing plate 210 and the bottom of the lower fixing plate 220 are provided with connecting protrusions 230 that match the shape of the arc grooves 240. The connecting protrusions 230 are disposed in the arc grooves 240 and slidably connected to the arc grooves 240.

[0023] In this embodiment, an anti-slip pad is provided at the bottom of the support base 100 and fixed to the ground with expansion bolts to prevent the device from shifting due to the tension of the cable during the laying process; the guide frame 200 is fixed to the upper end of the support base 100, and the horizontal wheel set 300 and the vertical wheel set 400 are arranged inside the guide frame 200; vertical first guide rails are provided on both sides of the front end face of the guide frame 200, and the two ends of the upper and lower guide rails in the horizontal wheel set 300 are slidably connected to the first guide rails on both sides, which can adjust the distance between the upper and lower guide rails to adapt to the size of the cable; and a spring 330 is also provided on the upper guide rail, the spring 330 being a compression spring 330, the lower end of the spring 330 being fixedly connected to the upper guide wheel 320. The upper end of the spring 330 is fixedly connected to the top of the guide frame 200. Through the extension and retraction adjustment of the spring 330, when the cable passes through, the spring 330 automatically retracts according to the diameter to maintain the contact force between the wheel set and the cable and reduce the deviation. The upper fixing plate 210 and the lower fixing plate 220 are fixedly connected to the top and bottom surfaces of the guide frame 200, respectively. The upper fixing plate 210 and the lower fixing plate 220 are provided with a second guide rail on their opposite end faces. The two ends of the left guide wheel 410 and the right guide wheel 420 of the vertical wheel set 400 are slidably connected to the second guide rail, thereby adjusting the distance between the left guide wheel 410 and the right guide wheel 420. When the cable passes through, the spacing can be adjusted according to the thickness of the cable to prevent the cable from deviating too much during the laying process and causing circuit damage.

[0024] Specifically, the first slider 311 in the lower guide wheel 310 is a frame with one open end, and its internal shape corresponds to the shape of the first guide rail. There are two first sliders 311, which are respectively installed on the first guide rails on both sides of the guide frame 200, with the open end facing inward, so that the first slider 311 can slide on the first guide rail. The lower crossbar 312 is set between the two first sliders 311, and the two ends of the lower crossbar 312 are respectively fixedly connected to the first sliders 311. The lower roller 313 is connected to the lower crossbar 312 through a bearing in the middle of the lower crossbar 312, so that the lower roller 313 can rotate flexibly with the lower crossbar 312 as the axis, ensuring a smooth transition of the cable during the laying process, reducing frictional resistance, and reducing wear on the photovoltaic cable.

[0025] To facilitate the fixing of the lower guide wheel 310, multiple equally spaced positioning holes are provided on the first guide rail, with the centers of the multiple positioning holes on the same vertical line and the distance between each pair of positioning holes being 5mm. A limiting through hole of the same size as the positioning hole is provided on the side wall of the first slider 311, and a fixing pin 314 is provided in the limiting through hole. The positioning hole and the limiting through hole are connected by the fixing pin 314. When it is necessary to adjust the height of the first slider 311, simply pull out the fixing pin 314, move the first slider 311 to the appropriate position, and then insert the fixing pin into the positioning hole to ensure that the lower guide wheel 310 is stable and the height is accurate, adapting to different cable requirements.

[0026] Furthermore, the upper guide wheel 320 includes a second slider 321, an upper crossbar 322, and an upper roller 323. The shape and number of the second slider 321 are the same as those of the first slider 311. The second sliders 321 are slidably mounted on the first guide rail with their open ends facing inward to ensure that the upper guide wheel 320 moves synchronously. The two ends of the upper crossbar 322 are fixed to the second sliders 321 on both sides. The upper roller 323 is connected to the upper crossbar 322 through bearings, and the upper roller 323 and the lower roller 313 are in the same vertical plane to ensure that the cable transitions smoothly between the upper and lower guide wheels 310. There are two springs 330. The lower ends of the springs 330 are fixedly connected to the upper ends of the second sliders 321 on both sides, and the upper ends of the springs 330 are fixedly connected to the top of the guide frame 200. The springs 330 apply pressure to the upper guide wheel 320 to keep the roller close to the cable, adapting to the needs of cables of different diameters and reducing damage to the photovoltaic cable.

[0027] The vertical wheel assembly 400 includes a symmetrically arranged left guide wheel 410 and a right guide wheel 420. The left guide wheel 410 includes a third slider 411, a left support rod 412, and a left roller 413. The internal shape of the third slider 411 corresponds to the shape of the second guide rail. There are two third sliders 411, which are slidably connected to the second guide rails of the upper fixed plate 210 and the lower fixed plate 220, respectively. Both ends of the left support rod 412 are fixedly connected to the two third sliders 411. The left roller 413 is mounted in the middle of the left support rod 412 via bearings to ensure the left guide wheel 410 rotates flexibly. To prevent damage when dragging the cable... To prevent lateral displacement, a locking through hole is provided on the side wall of the third slider 411, and a locking bolt is installed in the locking through hole. By tightening the locking bolt, the third slider 411 is firmly locked onto the second guide rail, making the left guide wheel 410 stable and stationary. The structure of the right guide wheel 420 is the same as that of the left guide wheel 410, and the connection method between the right guide wheel 420 and the second guide rail is also the same as the connection method between the left guide wheel 410 and the second guide rail. The third slider 411 of the right guide wheel 420 is also provided with a locking through hole and a locking bolt to ensure the stability of the right guide wheel 420. The left and right guide wheels work together to effectively prevent lateral displacement of the cable and improve overall stability. Furthermore, the surfaces of the upper roller, lower roller, left roller, and right roller are all covered with an elastic rubber layer. This rubber layer has high wear resistance and excellent gripping performance, effectively reducing friction when the cable contacts the roller, extending the service life of the roller, and ensuring that the cable does not slip during operation, further ensuring the stability and safety of cable transmission.

[0028] To adjust the angle of the vertical wheel assembly 400 to adapt to the movement path of the photovoltaic cable, arc grooves 240 are provided on both the bottom and top surfaces inside the guide frame 200. The projections of the two arc grooves 240 in the vertical direction coincide. Connecting protrusions 230 are provided on the upper end surface of the upper fixing plate 210 and the lower end surface of the lower fixing plate 220. The shape of the connecting protrusions 230 matches the shape of the arc grooves 240. The connecting protrusions 230 are set in the arc grooves 240 and can slide along the arc grooves 240, thereby adjusting the angle of the vertical wheel assembly 400. This allows for flexible adaptation to different cable routes and prevents the photovoltaic cable from being damaged due to excessive bending angles. To ensure the vertical guide rail remains fixed after movement, multiple threaded holes 241 are provided at the bottom of the arc groove 240, and two connecting through holes 231 are provided in the connecting protrusion 230, respectively located at both ends of the connecting protrusion 230, with the distance between each pair of threaded holes 241 equal to the distance between the two connecting through holes 231. A connecting bolt is provided in the connecting through hole 231, with the length of the connecting bolt greater than the depth of the connecting through hole 231, so that the connecting bolt passes through the connecting through hole 231 and is tightened with the threaded hole 241, ensuring that the vertical wheel assembly 400 is fixed in the preset position, thereby effectively avoiding cable damage caused by loosening during movement.

[0029] The general workflow of this utility model is as follows: First, adjust the height of the lower guide wheel 310 and the distance between the left guide wheel 410 and the right guide wheel 420 according to the thickness of the photovoltaic cable, so that the space enclosed by the upper guide wheel 320, lower guide wheel 310, left guide wheel 410, and right guide wheel 420 matches the diameter of the photovoltaic cable, so that the photovoltaic cable remains stable during movement and reduces deviation; according to the movement path of the photovoltaic cable, push the connecting protrusion 230 to slide along the arc groove 240, and adjust the angle of the vertical wheel group 400 to adapt to the movement path requirements of the photovoltaic cable, thereby avoiding damage to the photovoltaic cable due to excessive bending angle, so that the laid photovoltaic cable can maintain the best condition and improve its service life.
