Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cable technology, and in particular to a photovoltaic cable clip. Background Technology

[0002] With the increasing global demand for clean energy, the photovoltaic industry has ushered in a period of rapid development. The scale of photovoltaic power plant construction is constantly expanding, and its distribution is becoming increasingly widespread, ranging from large-scale ground-mounted centralized photovoltaic power plants to distributed rooftop photovoltaic power plants, with various application scenarios emerging one after another. In photovoltaic systems, photovoltaic cables play a crucial role in transmitting electrical energy, and the stability of their connections directly affects the power generation efficiency and operational safety of the entire system. However, in the early stages of photovoltaic power plant construction and operation, it was found that the methods used to fix photovoltaic cables were relatively simple and crude, resulting in many problems. Initially, the common practice was to use ordinary metal clips or ropes to fix the cables. Metal clips are usually simple in structure, providing clamping force only through simple spring plates or screw tightening. When photovoltaic cables need to be exposed to outdoor environments for a long time (enduring wind, sun, temperature changes, vibration, etc.), these clips have limited clamping force and are easily affected by external factors, gradually loosening, leading to cable displacement, shaking, or even detachment. This seriously affects the stability of power transmission, increases the risk of line faults, and causes great trouble for the operation and maintenance of power plants.

[0003] However, traditional cable clips are often simple in structure and limited in function, mostly using simple clamp-like structures or cable ties for binding and fixing. Clamp-like clips typically provide only limited clamping force, and when faced with the complex outdoor environment of photovoltaic cables, such as long-term exposure to wind, sun, and vibration, they are prone to loosening and falling off, leading to unstable cable connections and affecting the power transmission and normal operation of the photovoltaic system. While cable ties can achieve a certain degree of fixation, they lack adjustability. Once bound, it is difficult to readjust the tightness according to actual needs. Moreover, after prolonged outdoor use, cable ties are prone to aging and brittleness, reducing their fixing effect and even breaking, thus affecting the cable's security. Furthermore, traditional cable fixing methods have poor versatility; it is difficult to securely and appropriately fix photovoltaic cables of different thicknesses and sizes. Often, multiple sizes of clips or cable ties need to be prepared, which not only increases material management costs but also reduces work efficiency during actual installation, causing considerable inconvenience to construction personnel. These methods need to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0005] This utility model adopts the following technical solution: a photovoltaic cable clip, including a base plate, a support column fixedly installed at the top of the base plate, a fixing plate fixedly installed at the top of the support column, a fixing bracket fixedly installed at the top of the base plate and the bottom of the fixing plate, a groove opened inside the fixing bracket, an annular rack sleeved inside the groove, a gear one sleeved inside the groove, a rotating rod one fixedly installed on the surface of the gear one, a gear two fixedly installed at the other end of the rotating rod one, a moving groove opened on the surface of the fixing bracket, a moving column sleeved inside the moving groove, a rack one fixedly installed on the surface of the moving column, an arc-shaped clamping block fixedly installed at one end of the moving column, a moving rod sleeved on the outer surface of the rear end of the moving column, a sleeve groove opened at the bottom end of the moving rod, an insertion groove opened at the top of the fixing plate, threads opened on the outer surfaces of the moving rod and the insertion groove, a rotating block fixedly installed at the top of the moving rod, a rotating rod two sleeved inside the groove, and a gear three fixedly installed at one end of the rotating rod two.

[0006] Preferably, there are two sets of racks 1, symmetrically distributed on the surface of the moving column. The surface of gear 3 meshes with the surface of rack 1, and the surface of gear 2 meshes with the surface of rack 1. Here, the two sets of symmetrically distributed racks 1 make the power transmission more balanced. When gears 2 and 3 rotate and mesh with rack 1, forces can be applied simultaneously from both sides of the moving column, causing the moving column to move smoothly. This allows the arc-shaped clamping blocks to symmetrically approach or move away from the cable from both sides, ensuring a uniform distribution of clamping force on the cable. This avoids cable instability, displacement, or damage due to uneven force on one side, improving the stability and reliability of clamping and ensuring that the photovoltaic cable remains firmly fixed during long-term use.

[0007] Preferably, the surface of the annular rack meshes with the surface of gear one. There are four sets of movable columns and arc-shaped clamping blocks symmetrically distributed inside the fixed bracket. There is one set of movable rods, with one set of movable columns fitted inside the insertion slot. Here, the meshing of the annular rack and gear one allows power to be transmitted circumferentially along the annular rack. By rotating rod one, gear two, and other components, the four sets of symmetrically distributed movable columns and arc-shaped clamping blocks move synchronously, achieving omnidirectional clamping of the cable. Regardless of the cable's angle or position, it can be stably fixed, enhancing the stability of the clip's cable fixation.

[0008] Preferably, the number of fixing brackets is two sets, symmetrically distributed at the top of the base plate and the bottom of the fixing plate, and the number of gear one, gear two, rotating rod one, gear three, and rotating rod two are all four sets, circumferentially distributed inside the groove. Here, the two sets of symmetrically distributed fixing brackets make the entire buckle more balanced and stable in structure, and can evenly bear the tensile and compressive forces from the cable, avoiding structural deformation and damage due to excessive force on one side.

[0009] Preferably, both the surface of the rotating block and the surface of the arc-shaped clamping block are provided with anti-slip textures. These anti-slip textures are in multiple sets and are circumferentially distributed on the surfaces of both blocks. One end of the moving groove is connected to one end of the recessed groove. Here, the anti-slip textures on the surface of the arc-shaped clamping block increase the friction between the clamping block and the cable surface when in contact with the photovoltaic cable, making the cable more securely clamped.

[0010] Preferably, the surface of the base plate has a sliding groove, a limit rod is fixedly installed inside the sliding groove, a movable plate is sleeved on the outer surface of the limit rod, a spring is sleeved on the outer surface of the limit rod, a screw hole is formed on the surface of the movable plate, and a pull block is fixedly installed on the surface of the movable plate. Here, the spring is sleeved on the limit rod, and its two ends are respectively connected and fixed to the inner surface of the sliding groove and the surface of the movable plate. During the movement of the movable plate, the spring will be compressed or stretched accordingly, storing or releasing elastic potential energy.

[0011] Preferably, the pull block is T-shaped, and the number of limiting rods and springs is four sets, with each pair symmetrically distributed inside the base plate. The number of movable plates is two sets, also symmetrically distributed inside the base plate. Here, the four sets of limiting rods and springs symmetrically distributed in pairs inside the base plate, along with the two sets of symmetrically distributed movable plates, together constitute a symmetrical and balanced structural system. During use, whether subjected to external impact or undergoing position adjustment, this symmetrical distribution ensures that each component is evenly stressed, preventing structural deformation and component damage due to uneven stress on one side.

[0012] Preferably, one end of the spring is fixedly connected to the inner surface of the slide groove, and the other end of the spring is fixedly connected to the surface of the moving plate. The number of screw holes is three sets, arranged in an array on the surface of the moving plate. This method of fixing both ends of the spring clarifies the force relationship and position of the spring between the slide groove and the moving plate, ensuring that the spring can accurately store and release elastic potential energy during the movement of the moving plate, stably performing functions such as buffering and resetting. For example, when an external force causes the moving plate to move, the spring can be compressed or stretched according to design requirements, effectively absorbing impact force or assisting the moving plate in resetting, ensuring the normal operation of the entire base plate adjustment structure, maintaining the flexibility of the snap-fit ​​installation position and its stability under external force, and ensuring its reliable use in the photovoltaic system.

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

[0014] 1. In this utility model, by setting up a base plate, support column, fixing plate, fixing bracket, groove, ring rack, gear one, rotating rod one, gear two, moving groove, and moving column structure, when facing the complex outdoor environment where photovoltaic cables are located, the coordinated movement of multiple structures can prevent the cables from becoming loose or falling off, effectively preventing unstable cable connections and avoiding affecting the power transmission of the photovoltaic system and the normal operation of the equipment. In addition, by setting up an arc-shaped clamping block structure, photovoltaic cables of different thicknesses and sizes can be securely and appropriately fixed without the need to prepare various specifications of buckles or cable ties, effectively reducing material management costs and effectively improving the adaptability and versatility of the equipment.

[0015] 2. In this utility model, by setting a sliding groove, a limiting rod, a movable plate, a spring, screw holes, and a pull block structure, the sliding groove, the limiting rod, and the movable plate work together to allow the movable plate to slide linearly along the limiting rod within the sliding groove. This slidable structure allows for flexible adjustment of the movable plate's position according to actual installation requirements. Then, using the screw holes on the movable plate, bolts and other connecting parts are used to fix the buckle to the corresponding installation base, improving the flexibility and adaptability of the buckle installation and facilitating installation and fixing in various photovoltaic scenarios.

[0027] Example 1

[0028] Please see Figures 1-7This utility model provides a technical solution: a photovoltaic cable clip, including a base plate 1, a support column 2 fixedly installed at the top of the base plate 1, a fixing plate 3 fixedly installed at the top of the support column 2, a fixing bracket 4 fixedly installed at the top of the base plate 1 and the bottom of the fixing plate 3, a groove 5 is formed inside the fixing bracket 4, an annular rack 6 is fitted inside the groove 5, a gear 7 is fitted inside the groove 5, a rotating rod 8 is fixedly installed on the surface of the gear 7, a gear 9 is fixedly installed at the other end of the rotating rod 8, a moving groove 10 is formed on the surface of the fixing bracket 4, a moving column 11 is fitted inside the moving groove 10, a rack 12 is fixedly installed on the surface of the moving column 11, an arc-shaped clamping block 13 is fixedly installed at one end of the moving column 11, a moving rod 14 is fitted on the outer surface of the rear end of the moving column 11, a fitting groove 15 is formed at the bottom end of the moving rod 14, an insertion groove 16 is formed at the top of the fixing plate 3, and threads 17 are formed on the outer surfaces of the moving rod 14 and the insertion groove 16. The top end of the moving rod 14 is fixed... A rotating block 18 is installed, and a rotating rod 19 is fitted inside the groove 5. A gear 20 is fixedly installed at one end of the rotating rod 19. The photovoltaic cable is placed in a suitable position in the fixed bracket 4, the rotating block 18 is held and rotated, the rotating block 18 drives the moving rod 14 to rotate. Relying on the engagement of the moving rod 14 with the thread 17 of the insertion groove 16, the moving rod 14 moves in the insertion groove 16. The moving rod 14 drives the fitted moving column 11 to move along the moving groove 10. The rack 12 on the moving column 11 engages with the gear... Gear 29 and gear 320 mesh. Gear 29 is connected to gear 7 via rotating rod 18. Gear 7 meshes with the ring rack. When rotating block 18 rotates, power is transmitted sequentially through the above components, driving four sets of moving columns 11 to move synchronously. The arc-shaped clamping block 13 at one end of the moving column 11 approaches the photovoltaic cable until the arc-shaped clamping block 13 tightly clamps the cable. The self-locking of the thread 17 stabilizes the clamping state, completing the buckling and fixing operation of the photovoltaic cable and enabling it to fix cables of different sizes.

[0029] Please see Figures 1-7There are two sets of racks 12, symmetrically distributed on the surface of the moving column 11. The surface of gear 3 20 meshes with the surface of rack 12, the surface of gear 2 9 meshes with the surface of rack 12, and the surface of ring rack 6 meshes with the surface of gear 1 7.

There are four sets of gears 1 7, 2 9, 1 rotating rod, 3 20, and 2 rotating rod 19, circumferentially distributed inside the groove 5. The surfaces of rotating block 18 and arc-shaped clamping blocks 13 are provided with anti-slip textures 21. There are multiple sets of anti-slip textures 21 on the surfaces of rotating block 18 and arc-shaped clamping blocks 13. The surface of block 13 is circumferentially distributed. One end of the moving groove 10 is connected to one end of the groove 5. The pull block 27 is T-shaped. There are four sets of limiting rods 23 and springs 25, and two sets are symmetrically distributed inside the base plate 1.

One end of the spring 25 is connected and fixed to the inner surface of the slide groove 22, and the other end of the spring 25 is connected and fixed to the surface of the moving plate 24. There are three sets of screw holes 26, which are arrayed on the surface of the moving plate 24. The T-shaped pull block 27 is designed to prevent the pull block 27 from slipping out of the operator's hand when pulling. It provides a more stable operating point, ensuring that the moving plate 24 can be pulled accurately and powerfully, improving the reliability and accuracy of the operation, and avoiding inconvenience or errors caused by the unreasonable shape of the pull block 27.

[0030] Example 2

[0031] Please see Figure 4 The base plate 1 has a groove 22 on its surface. A limit rod 23 is fixedly installed inside the groove 22. A movable plate 24 is sleeved on the outer surface of the limit rod 23. A spring 25 is sleeved on the outer surface of the limit rod 23. A screw hole 26 is opened on the surface of the movable plate 24. A pull block 27 is fixedly installed on the surface of the movable plate 24. When fixing the equipment, hold the pull block 27 and pull it outward. The pull block 27 drives the movable plate 24 to slide along the limit rod 23 in the groove 22. At this time, the spring 25 is stretched and stores elastic potential energy. After the movable plate 24 moves to the appropriate position, it is fixed to the corresponding mounting base through the screw hole 26 on the movable plate 24 using bolts or other connecting parts, thus completing the installation and fixing operation. If the position needs to be adjusted later, loosen the connecting parts. The spring 25 will drive the movable plate 24 to reset by relying on its elastic potential energy. Alternatively, the pull block 27 can be pulled again to move the movable plate 24 to a new appropriate position and then fix it.

[0032] Working principle: When using the equipment, place the photovoltaic cable in a suitable position within the fixed bracket 4. Then, contact the surface of the anti-slip texture 21 with your hand, and rotate the rotating block 18. The rotation of the rotating block 18 drives the moving rod 14 to rotate. Relying on the engagement of the thread 17 of the insertion slot 16, the moving rod 14 moves within the insertion slot 16. The moving rod 14 drives the sleeved moving column 11 to move along the moving slot 10. The rack 12 on the moving column 11 meshes with gear 9 and gear 20. Gear 9 is connected to gear 7 through the rotating rod 8. Gear 7 meshes with the ring rack. When the rotating block 18 rotates, the power is transmitted sequentially through the above components, driving the four sets of moving columns 11 to move synchronously. The arc-shaped clamping block 13 at one end of the moving column 11 moves accordingly. Approaching the photovoltaic cable until the arc-shaped clamping block 13 tightly clamps the cable, the self-locking of the thread 17 ensures a stable clamping state, completing the buckling and fixing operation of the photovoltaic cable and enabling the fixing of cables of different sizes. Hold the pull block 27 and pull it outward. The pull block 27 drives the moving plate 24 to slide along the limit rod 23 in the slide groove 22. At this time, the spring 25 is stretched and stores elastic potential energy. After the moving plate 24 moves to the appropriate position, it is fixed to the corresponding installation base through the screw hole 26 on the moving plate 24 using bolts or other connecting parts, completing the installation and fixing operation. If the position needs to be adjusted later, loosen the connecting parts. The spring 25 uses elastic potential energy to drive the moving plate 24 to reset, or pull the pull block 27 again to move the moving plate 24 to a new appropriate position and then fix it.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
