Description

Technical Field

[0001] This utility model relates to the field of wire harness storage technology, specifically a photovoltaic panel cable storage device. Background Technology

[0002] With the global energy structure shifting towards clean energy, the photovoltaic industry has achieved leapfrog development, and the application scenarios of photovoltaic panels continue to expand. From large-scale ground-mounted photovoltaic power stations to industrial and commercial building rooftops, and then to residential distributed photovoltaic systems, a large number of cables are needed to achieve electrical connection between photovoltaic panels and equipment such as inverters and combiner boxes.

[0003] The applicant discovered through a search that a Chinese patent, "A Photovoltaic Power Station Cable Storage and Fixing Device," with publication number "CN218145035U," primarily uses a rotating winding roller to wind the cable, thus achieving cable storage. The winding roller can be driven manually or electrically. The configuration of the drive motor, lead screw, and bushing facilitates control of the slider's up-and-down movement or locking, increasing the clamping effect of the pressure plate on the cable during storage or release. However, analysis revealed that this device has poor adaptability, cannot accommodate spools with different inner diameters, and cannot stably fix the spools for cable storage, resulting in poor stability and affecting storage efficiency. Therefore, we propose a photovoltaic panel cable storage device. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic panel cable storage device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic panel cable storage device, comprising a storage device body and a spool located outside the storage device body for winding photovoltaic panel cables. The storage device body includes an L-shaped storage frame, a dynamic fastening assembly, and a movable stretching assembly. Two reinforcing connecting blocks are fixedly connected to the front and rear inner walls of the left side of the L-shaped storage frame. The dynamic fastening assembly includes a fixed plate, a servo motor, a drive disc, and a fixed arm. The front and rear sections of the fixed plate are respectively connected to the two reinforcing connecting blocks. The servo motor is connected to the left side of the fixed plate. The drive shaft on the right side of the servo motor passes through the fixed plate and is connected to the left side of the drive disc. A track groove is formed on the surface of the drive disc, and the track groove is slidably connected to the fixed arm.

[0006] As a further embodiment of this utility model: a fixed slider is fixedly connected to the right side of the fixed plate, and a sliding groove is provided on the surface of the fixed slider. The inner wall of the sliding groove is slidably connected to the outer surface of the left side of the fixed arm.

[0007] As a further embodiment of this utility model: a sliding drive block is connected to the end of the left side of the fixed arm away from the fixed slider, and the surface of the sliding drive block is slidably connected to the inner wall of the track groove.

[0008] As a further embodiment of this utility model: the fixed arm surface is provided with a sliding clamping groove, the movable tensioning assembly includes a sliding reinforcing head, a sliding shaft and a compression spring, the left and right sides of the sliding shaft are connected to the left and right sides of the sliding clamping groove, the surface of the sliding reinforcing head is provided with a sliding circular hole, the sliding reinforcing head is slidably connected to the surface of the sliding shaft based on the sliding circular hole of the sliding shaft, the compression spring is located on the outside, and the two ends of the compression spring are respectively connected to the left side of the sliding clamping groove and the left side of the sliding reinforcing head.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model, through the setting of a dynamic clamping component, can fix spools of photovoltaic panel cables of different specifications. When it is necessary to store photovoltaic panel cables, the spool is first placed on the outside of the fixing arm. At this time, the spool is in an unfixed state. Then, the servo motor is started through the control panel. The servo motor drives the drive disk to rotate. The rotation of the drive disk drives the sliding drive block that is slidably connected to the track slide to slide. Since the sliding drive block is slidably connected to the fixed slider, multiple fixing arms can slide along the fixed slider at the same time and move away from each other until the outer surface of multiple fixing arms abuts against the inner wall of the spool and thus fixes the spool. Through the cooperation of this combination, spools of different inner diameter specifications can be fixed, thereby greatly improving the storage efficiency of photovoltaic cables.

[0014] 2. This utility model features a movable tensioning component. In addition to the different inner diameters of the inner rings, the widths of the spools of different specifications also vary. By incorporating a sliding reinforcing head, the sliding reinforcing head can be controlled to slide along the surface of the sliding shaft, thereby compressing the spring. By controlling the distance between the sliding reinforcing head and the limiting reinforcing head, the model can control the spools of different widths, thereby improving the storage efficiency and compatibility of photovoltaic cable.

[0015] 3. This utility model has rolling grooves on the surfaces of the sliding reinforcement head and the limiting reinforcement head, and rolling balls are set inside the rolling grooves, so that multiple rolling balls can simultaneously abut against the surface of the spool, allowing the spool to be rotated manually or electrically, avoiding the limitation of needing to wrap the cable around the spool surface, and greatly improving the storage efficiency.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0025] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see the appendix Figure 1 - Appendix Figure 6 This utility model discloses a photovoltaic panel cable storage device, including a storage device body 1 and a spool 2 located outside the storage device body 1 for winding photovoltaic panel cables. The storage device body 1 includes an L-shaped storage frame 3, a dynamic fastening assembly 4, and a movable stretching assembly 5. Two reinforcing connecting blocks 31 are fixedly connected to the front and rear inner walls of the left side of the L-shaped storage frame 3. The dynamic fastening assembly 4 includes a fixed plate 41, a servo motor 42, a drive disk 43, and a fixed arm 44. The front and rear ends of the fixed plate 41 are respectively connected to the two reinforcing connecting blocks 31. The servo motor 42 is connected to the left side of the fixed plate 41. The drive shaft on the right side of the servo motor 42 passes through the fixed plate 41 and is connected to the left side of the drive disk 43. A track groove 431 is opened on the surface of the drive disk 43, and the track groove 431 is slidably connected to the fixed arm 44.

[0027] In embodiment 1, a fixed slider 45 is fixedly connected to the right side of the fixed plate 41. A sliding groove is provided on the surface of the fixed slider 45. The inner wall of the sliding groove is slidably connected to the outer left side of the fixed arm 44. A sliding drive block 441 is connected to the end of the left side of the fixed arm 44 away from the fixed slider 45. The surface of the sliding drive block 441 is slidably connected to the inner wall of the track groove 431. A sliding clamping groove 442 is provided on the surface of the fixed arm 44. The movable tensioning assembly 5 includes a sliding reinforcing head 51, a sliding shaft 52, and a compression spring 53. The left and right sides of the sliding shaft 52 are connected to the left and right sides of the sliding clamping groove 442. A sliding round hole is provided on the surface of the sliding reinforcing head 51. The sliding reinforcing head 51 is slidably connected to the surface of the sliding shaft 52 based on the sliding round hole of the sliding shaft 52. The compression spring 53 is located on the outside. The two ends of the compression spring 53 are respectively connected to the left side of the sliding clamping groove 442 and the left side of the sliding reinforcing head 51.

[0028] Specifically, by setting the dynamic clamping component 4, the spools 2 of photovoltaic panel cables of different specifications can be fixed. When it is necessary to store the photovoltaic panel cables, the spool 2 is first placed outside the fixing arm 44. At this time, the spool 2 is in an unfixed state. At this time, the servo motor 42 is started through the control panel 7. The servo motor 42 drives the drive disk 43 to rotate. The rotation of the drive disk 43 drives the sliding drive block 441, which is slidably connected to the track slide 431, to slide. Since the sliding drive block 441 is slidably connected to the fixing slider 45, multiple fixing arms 44 can slide along the fixing slider 45 at the same time and move away from each other until the outer surface of multiple fixing arms 44 abuts against the inner wall of the spool 2 and thus fixes the spool 2. Through the cooperation of this combination, spools 2 of different inner diameter specifications can be fixed, thereby greatly improving the storage efficiency of photovoltaic cables.

[0029] In actual production and use, the spool 2 is first placed on the right side outside the multiple fixed arms 44. Then, the servo motor 42 is started. As the surface of the drive disk 43 rotates, the track groove 431 on the surface of the drive disk 43 is arc-shaped, which allows the multiple sliding drive blocks 441 to move away from the center of gravity of the drive disk 43. The multiple fixed arms 44 that move away from each other expand outward at the same time until they abut against the inner wall of the spool 2 of different specifications. The adaptability is very high. Since different specifications of cables require different specifications of spool 2 in actual use, this device can fix spool 2 with different inner diameters, which is more efficient.

[0030] In embodiment 2, a limiting reinforcement head 443 is provided at the right end of the fixed arm 44. The limiting reinforcement head 443 and the sliding reinforcement head 51 are both provided with rolling grooves on their close sides. The rolling grooves are provided with balls 6. The balls 6 on the left and right sides are in contact with the left and right sides of the spool 2. The surface of the fixed arm 44 is in contact with the inner wall of the inner ring of the spool 2. A control panel 7 is provided on the left side of the L-shaped storage rack 3. The control panel 7 is electrically connected to the servo motor 42.

[0031] Specifically, in actual use, before the servo motor 42 is used to fix the spool 2 vertically, the sliding reinforcement head 51 needs to be pulled along the left sliding shaft 52 to compress the spring until the limiting reinforcement head 443 moves to the left edge of the spool 2. Then, the hand is released. Under the pushing action of the spring, the limiting reinforcement head 443 is pushed to the right, thereby limiting the spool 2 in the horizontal direction. This achieves complete spatial limitation of the spool 2. When it is necessary to store the cable, the spool 2 can be rotated manually or by other electric devices to achieve the effect of quickly storing the cable, greatly improving storage efficiency.

[0032] Working principle:

[0033] First, when it is necessary to store photovoltaic panel cables, the spool 2 is placed outside the fixed arm 44. At this time, the spool 2 is in an unfixed state. Then, the servo motor 42 is started through the control panel 7. The servo motor 42 drives the drive disk 43 to rotate. The rotation of the drive disk 43 drives the sliding drive block 441, which is slidably connected to the track slide 431, to slide. Since the sliding drive block 441 is slidably connected to the fixed slider 45, multiple fixed arms 44 can slide simultaneously along the fixed slider 45 and move away from each other until the outer surface of multiple fixed arms 44 abuts against the inner wall of the spool 2, thereby fixing the spool 2. Through the cooperation of this combination, spools 2 with different inner diameter specifications can be fixed. In addition to the different inner diameters, the widths of spools 2 with different specifications are also different. By setting a sliding reinforcement head 51, the sliding reinforcement can be controlled. The retaining head 51 slides along the surface of the sliding shaft 52, thereby compressing the spring. By controlling the distance between the sliding retaining head 51 and the limiting retaining head 443, the effect of controlling the spools 2 of different widths can be achieved. The surfaces of the sliding retaining head 51 and the limiting retaining head 443 are provided with rolling grooves, and ball bearings 6 are provided inside the rolling grooves, so that multiple ball bearings 6 can simultaneously abut against the surface of the spool 2, allowing the spool 2 to be rotated manually or electrically, avoiding the limitation of needing to wrap the cable around the surface of the spool 2. After storage, the sliding retaining head 51 is pushed to the left, causing the spool 2 to disengage from the limit in the horizontal direction. Then, the servo motor 42 is started to rotate in the opposite direction, causing multiple retaining arms 44 to converge with each other, thereby causing the spool 2 and the stored cable to disengage from the limit and be directly removed. At this point, the entire workflow is completed.
