Description

Technical Field

[0001] This utility model relates to the field of cable wiring technology, and in particular to a cable wiring guide device for photovoltaic power stations. Background Technology

[0002] In the construction and operation and maintenance of photovoltaic power plants, cable laying is a core link to ensure power transmission efficiency and system security. Before laying cables, it is often necessary to guide the cables into protective pipes to avoid cable damage.

[0003] However, there are still significant technical challenges in the current cable installation work for photovoltaic power plants. On the one hand, in the wiring process of large-scale photovoltaic power plants, the length of cables to be laid can reach tens of thousands of meters, and the weight of a single cable is relatively large. In the current operation, the cables are mostly pushed manually into the pipes, which often requires the cooperation of multiple people. Moreover, when facing long protective pipes, the friction between the cable and the pipe wall increases linearly with the length of the cable, the pushing resistance increases sharply, the physical effort required is greater, and the wiring efficiency is low due to the time and effort spent. On the other hand, during the pre-burying or storage of protective pipes, debris such as gravel, sand, and concrete debris can easily remain on the inner wall. Manual installation lacks effective pre-treatment and guiding protection. During the process of guiding the cable into the protective pipe, the outer sheath of the cable rubs directly against the debris inside the pipe, which may cause problems such as scratches and cracks in the insulation layer. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable wiring guide device for photovoltaic power stations, which solves the technical problems of low efficiency in manual wiring and conduit insertion, and the damage and cracking of the insulation layer caused by friction between the cable and debris inside the protective conduit during the pushing process.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a photovoltaic power station cable wiring guide device, including a guide platform and a protective tube placed on one side of the guide platform, a cable passing through the guide platform, and wire guiding mechanisms suitable for cables of different diameters symmetrically arranged on both sides of the guide platform, and a cleaning mechanism for removing debris from the protective tube is provided at one end of the cable.

[0006] The threading guide mechanism includes a transmission box mounted on a guide platform. The transmission box contains a transmission chain with multiple gears meshing on its inner side. A transmission shaft is mounted on each gear and rotatably connected to a rotating hole in the transmission box. A motor that drives one of the transmission shafts is mounted on the transmission box. A traction roller and a limiting disc are sequentially fitted on the outer side of the transmission shaft from bottom to top. A locking nut is threaded onto the transmission shaft. An adjustment assembly that drives the two transmission boxes to move relative to each other is provided inside the guide platform.

[0007] A further improvement is that rubber pads are installed on the outer side of the traction rollers, and the drive shaft is provided with external threads that are compatible with the locking nut.

[0008] A further improvement is that the adjusting component includes a lead screw rotatably connected to the rotating hole of the guide table, a turntable fixed to the front end of the lead screw, threaded sliders symmetrically installed at both ends of the lead screw, and the tops of the two threaded sliders are respectively connected to two transmission boxes. Guide grooves are symmetrically opened on both sides of the guide table, and guide sliders sliding in the guide grooves are installed on both sides of the two transmission boxes.

[0009] A further improvement is that the two ends of the lead screw are respectively provided with positive and negative threads, and the two threaded sliders are respectively threadedly connected to the positive and negative threads.

[0010] A further improvement is that the cleaning mechanism includes a sleeve fitted onto one end of the cable, a debris-removing ring plate adapted to the inner diameter of the protective tube fixedly connected to the sleeve, a rotating cylinder rotatably connected to the sleeve, oblique friction plates installed in a circular array on the outer side of the rotating cylinder, and bristles installed on the sleeve.

[0011] A further improvement is that the inner diameter of the protective tube is 1.5 times the diameter of the cable, the angle between the inclined friction plate and the axis of the rotating drum is 15°-30°, and the outer side of the inclined friction plate is in close contact with the inner wall of the protective tube.

[0012] By employing the above technical solution, this utility model provides a photovoltaic power station cable wiring guide device, which has at least the following beneficial effects:

[0013] 1. This utility model starts two motors synchronously and reverses them relative to each other, which then drives one of the drive shafts to rotate, thereby driving the gears on this drive shaft to rotate, which in turn drives the drive chain to rotate, which in turn drives all the gears to rotate synchronously, thus causing all the drive shafts to rotate, and driving the traction rollers on them to rotate, thereby moving the cable to be threaded into the protective tube. No manual threading is required, which improves threading efficiency and saves manpower.

[0014] 2. This utility model drives the lead screw to rotate by rotating the turntable, which in turn drives the threaded sliders at the front and rear ends of the lead screw to move closer or further apart, thereby causing the guide sliders on both sides of the transmission box to slide in the guide groove, thus adjusting the distance between the two transmission boxes to accommodate cables of different diameters and improving the applicability of the device.

[0015] 3. This utility model involves placing a sleeve on the end of the cable. When the cable pushes the sleeve into the protective tube, the inclined friction plate on the outer rotating cylinder of the sleeve contacts and is pressed against the inner wall of the protective tube. Under the reaction force of the inner wall of the protective tube, the rotating cylinder is driven to rotate. Thus, the brush on the rotating cylinder cleans the impurities on the inner wall of the protective tube, and the debris is scraped off by the debris removal ring plate, avoiding friction between the debris and the cable, which would damage the cable sheath.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Addressing the issues of low efficiency in manual cable routing and conduit insertion, and the resulting scratches and cracks in the insulation layer due to friction between the cable and debris inside the conduit during insertion, this embodiment provides a photovoltaic power station cable routing guide device. This device automatically guides the cable 3 through the protective conduit 2, eliminating the need for manual routing and improving efficiency. Furthermore, it cleans debris from inside the protective conduit 2 during the routing process, preventing damage to the cable 3's sheath. Please refer to... Figures 1-5 The photovoltaic power station cable wiring guide device includes a guide platform 1 and a protective tube 2 placed on one side of the guide platform 1. A cable 3 passes through the guide platform 1. Cable threading guide mechanisms 4 suitable for cables 3 of different diameters are symmetrically arranged on both sides of the guide platform 1. A cleaning mechanism 5 is provided at one end of the cable 3 to remove debris from the protective tube 2. The cable 3 is guided into the interior of the protective tube 2 by the cable threading guide mechanism 4, eliminating the need for manual threading and improving threading efficiency. At the same time as the cable 3 passes through the interior of the protective tube 2, the cleaning mechanism 5 brushes and scrapes away debris from the interior of the protective tube 2, thereby preventing debris from rubbing against the cable 3 sheath and causing damage to the sheath.

[0030] Since existing technologies often involve manual wiring and conduit insertion, which is inefficient, this device is equipped with a wire threading guide mechanism 4. The wire threading guide mechanism 4 includes a transmission box 41 mounted on a guide table 1. A transmission chain 42 is installed inside the transmission box 41. Multiple gears 43 are meshed on the inner side of the transmission chain 42. A transmission shaft 44 is rotatably connected to the gears 43 and is mounted on the gears 43. A motor 45 is installed on the transmission box 41 to drive one of the transmission shafts 44 to rotate. A traction roller 46 and a limiting disc 47 are sequentially fitted on the outer side of the transmission shaft 44 from bottom to top. The transmission shaft 44 is threaded. A locking nut 48 is connected to the guide table 1, which is equipped with an adjusting component 49 that drives two transmission boxes 41 to move relative to each other. The two motors 45 are started synchronously and reversed relative to each other, which then drives one of the transmission shafts 44 to rotate, thereby driving the gear 43 on the transmission shaft 44 to rotate, and driving the transmission chain 42 to rotate, which in turn drives all the gears 43 to rotate synchronously, thereby causing all the transmission shafts 44 to rotate, and driving the traction rollers 46 on them to rotate, thereby driving the cable 3 to move and pass through the protective tube 2. No manual threading is required, which improves the threading efficiency and saves manpower.

[0031] Furthermore, rubber pads are installed on the outer side of the traction rollers 46. The rubber pads better protect the cable 3, preventing damage to the cable sheath during transmission, and increase friction, making the transmission of the cable 3 more stable. The drive shaft 44 is provided with an external thread that matches the locking nut 48. The limiting plate 47 is fixed on the drive shaft 44 by the locking nut 48, thereby limiting the cable 3 and preventing it from falling off the threading guide mechanism 4 during transmission.

[0032] Since different diameter cables 3 are often encountered during the guiding threading process, the device is also equipped with a pitch adjustment component 49. The pitch adjustment component 49 includes a lead screw 491 rotatably connected to the rotating hole of the guide table 1. A turntable 492 is fixed to the front end of the lead screw 491. Threaded sliders 493 are symmetrically installed at both ends of the lead screw 491, and the tops of the two threaded sliders 493 are respectively connected to two transmission boxes 41. Guide grooves 494 are symmetrically opened on both sides of the guide table 1. Guide sliders 495 that slide in the guide grooves 494 are installed on both sides of the two transmission boxes 41.

[0033] The lead screw 491 has positive and negative threads at both ends, and two threaded sliders 493 are threaded onto the positive and negative threads respectively. When facing cables 3 of different diameters, rotating the turntable 492 drives the lead screw 491 to rotate, which in turn drives the threaded sliders 493 at the front and rear ends of the lead screw 491 to move closer or further apart. This causes the guide sliders 495 on both sides of the transmission box 41 to slide in the guide groove 494, thereby adjusting the distance between the two transmission boxes 41 to accommodate cables 3 of different diameters and improving the applicability of the device.

[0034] Example 2

[0035] Since the protective pipe 2 often contains debris such as gravel, in order to prevent the cable 3 from being scratched by debris during passage, based on embodiment one, as follows: Figures 1-5 As shown, the device is also equipped with a cleaning mechanism 5, which includes a sleeve 51 fitted onto one end of the cable 3. A debris removal ring plate 52 adapted to the inner diameter of the protective tube 2 is fixedly connected to the sleeve 51. A rotating cylinder 53 is rotatably connected to the sleeve 51. Inclined friction plates 54 are installed in a ring array on the outer side of the rotating cylinder 53. Brush bristles 55 are installed on the sleeve 51.

[0036] The inner diameter of the protective tube 2 is 1.5 times the diameter of the cable 3. The angle between the inclined friction plate 54 and the axis of the rotating drum 53 is 15°-30°, and the outer side of the inclined friction plate 54 is in close contact with the inner wall of the protective tube 2. The sleeve 51 is fitted onto the end of the cable 3. When the cable 3 pushes the sleeve 51 into the protective tube 2, the inclined friction plate 54 on the rotating drum 53 outside the sleeve 51 contacts the inner wall of the protective tube 2. As the cable 3 moves forward in a straight line in the protective tube 2, the inclined friction plate 54 contacts and is pressed against the inner wall of the protective tube 2. Since the inclined friction plate 54 is inclined on the rotating drum 53, when it is pushed by the reaction force of the inner wall of the protective tube 2, it drives the rotating drum 53 to rotate. Thus, the brush bristles 55 on the rotating drum 53 clean the impurities on the inner wall of the protective tube 2, and the impurity is scraped off by the impurity discharge ring plate 52, so as to avoid the impurities from rubbing against the cable 3 and causing damage to the cable 3 sheath.
