Description

Technical Field

[0001] This invention belongs to the field of cable laying technology, specifically a cable laying device and method for laying photovoltaic DC cables. Background Technology

[0002] Photovoltaic power generation, as a clean and renewable energy source, has been widely used globally. In photovoltaic power generation systems, photovoltaic DC cables serve as a crucial bridge connecting photovoltaic panels to electrical loads. These cables need to efficiently and stably transmit the DC power generated by the photovoltaic panels to ensure the normal operation of the power system. Therefore, the laying of photovoltaic DC cables has become a key step in the construction of photovoltaic power generation systems. Currently, a cable laying frame is typically used when laying photovoltaic DC cables. The rotating rollers on the frame allow workers to quickly lay the cables, thus completing the installation work.

[0003] In existing technologies, photovoltaic DC cables often require conduit installation during the laying process. Laying and installing each cable individually is time-consuming. While laying and installing multiple cables together avoids the time wasted on individual installations, it still requires workers to use clips to secure the cables together during the laying process to prevent them from becoming loose. This significantly increases the complexity of the operation.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-10As shown in the embodiment of the present invention, a wire-laying device for photovoltaic DC cables includes a wire-laying frame 1, a wire-laying roller 42 rotatably connected to the wire-laying frame 1, two support frames 7 arranged on one side of the wire-laying frame 1, and a feeding cylinder 8 fixedly connected to the top of each of the two support frames 7. A feeding auger 10 is rotatably connected to the inner cavity of the feeding cylinder 8. A motor 9 is fixedly installed on the outer wall of the feeding cylinder 8 away from the wire-laying frame 1. The output end of the motor 9 extends into the inner cavity of the feeding cylinder 8 and is fixedly connected to one end of the feeding auger 10. A storage box 14 is provided above the inner cavity of each of the two feeding cylinders 8, and a plurality of materials are evenly placed in each storage box 14. A cable bundle 32 is placed in one storage box 14, and several cable bundles 33 are evenly placed in another storage box 14. An L-shaped guide plate 18 is fixed to the side of the feed cylinder 8 near the wire feeding frame 1. The L-shaped guide plate 18 is equipped with a pushing mechanism. A cable guiding mechanism is provided between the wire feeding frame 1 and the feed cylinder 8. A guide block 21 is provided on the side of the cable guiding mechanism near the feed cylinder 8. The guide block 21 is fixed to both L-shaped guide plates 18. During operation, the wire feeding roller 42 on the wire feeding frame 1 rotates to start feeding the wire. The operator first pulls the ends of multiple cables and passes them through the cable guiding mechanism and the guide block 21 in sequence. Then, the two storage boxes 14 are respectively... After several bundled wire blocks 32 and 33 are placed into the two feeding cylinders 8, the two storage boxes 14 are then pulled out. Motor 9 is then started, driving the feeding auger 10 to rotate. This causes the bundled wire blocks 32 and 33 to be pushed one by one onto the L-shaped guide plate 18 by the feeding auger 10. The pushing mechanism on the two L-shaped guide plates 18 pushes the bundled wire blocks 32 and 33 to guide block 21. After the bundled wire blocks 32 and 33 are locked together, multiple cables can be bundled and secured, solving the problem in existing technologies. During the laying process of photovoltaic DC cables, it is often necessary to run them through conduits. If each cable is laid and run through a conduit individually, it will waste a lot of time. If multiple cables are laid and run through a conduit at the same time, although this method can avoid the time wasted by individual conduit running, in order to prevent multiple cables from becoming loose in the laying path, the workers still need to use clips to fix multiple cables together at the same time, which will greatly increase the cumbersome operation for the workers. Both motor 9 and the pushing mechanism work intermittently, which can achieve the effect of fixing the cables at intervals.

[0023] A baffle 12 is fixed to the side of the feed cylinder 8 away from the wire feeding frame 1. An outlet 11 is provided on the side of the feed cylinder 8 closest to the wire feeding frame 1. The shape of the outlet 11 is compatible with both the first wire bundle block 32 and the second wire bundle block 33. A through groove 13 is provided on the opposite sides of both feed cylinders 8. During operation, the baffle 12 on one side of the feed cylinder 8 allows the operator to place one end of the storage box 14, filled with the first wire bundle block 32 or the second wire bundle block 33, against the baffle 12, thereby positioning the storage box 14 and facilitating its movement. After the storage box 14 is pulled out, several wire bundle blocks 1 32 and wire bundle blocks 2 33 can fall accurately between the blades of the feeding auger 10. When the motor 1 9 starts, the feeding auger 10 will push several wire bundle blocks 1 32 or wire bundle blocks 2 33 out one by one from the side of the discharge port 11 and slide onto the L-shaped guide plate 18. The inner side of the discharge port 11 is chamfered to facilitate the transition of wire bundle blocks 1 32 and wire bundle blocks 2 33 from the feeding auger 10 to the discharge port 11. The inner wall of the feeding cylinder 8 is provided with an arc surface to facilitate the adaptation of wire bundle blocks 1 32 and wire bundle blocks 2 33.

[0024] The storage box 14 is evenly provided with placement slots, which are compatible with both the first wire bundle block 32 and the second wire bundle block 33. The top two sides of the storage box 14 are provided with hanging ears, which are compatible with the top two sides of the feed cylinder 8. One side of the bottom of the storage box 14 has a groove 15, and the other side of the bottom of the storage box 14 has a through groove 16. A base plate 17 is slidably connected to the through groove 16, extending through one side of the through groove 16 into the groove 15. During operation, the operator can first insert the base plate 17 along the through groove 16 into the bottom of the storage box 14 until it fits against the groove 15, and then place several first wire bundle blocks 32 or second wire bundle blocks 33 into the storage box one by one. Place the storage box 14 in the slot, then slide the storage box 14 down from above the feed cylinder 8, while simultaneously making one end of the storage box 14 fit against the inside of the baffle 12 until the hanging ear on the storage box 14 contacts the top of the feed cylinder 8. At this time, the through groove 16 on the storage box 14 corresponds to the through groove 13 on the feed cylinder 8. The operator uses their hand to pull out the bottom plate 17 through the through groove 13, causing several wire bundle blocks 32 or wire bundle blocks 33 in the storage box 14 to fall between the blades of the feed auger 10. After that, the operator pulls the storage box 14 out from the feed cylinder 8 from bottom to top. Repeating this process can achieve the filling of wire bundle blocks 32 and wire bundle blocks 33.

[0025] The feeding mechanism includes a lead screw 23, a second motor 24, a threaded sleeve 25, and a feeding block 26. Each of the two L-shaped guide plates 18 has a bracket 22 below it, which is fixedly connected to the support frame 7. A lead screw 23 is rotatably connected between the two brackets 22. A second motor 24 is fixedly mounted on the outer wall of one of the brackets 22. The output end of the second motor 24 is fixedly connected to one end of the lead screw 23. The lead screw 23 has symmetrical double threads with opposite directions of rotation. A pair of symmetrically distributed threaded sleeves 25 are threaded to the outer side of the lead screw 23. A feeding block 26 is fixedly connected to the top of each threaded sleeve 25. The feeding block 26 is slidably connected to the L-shaped guide plate 18. The bottom of the L-shaped guide plate 18... The part is provided with a guide groove 20, one side of which is open. The threaded sleeve 25 is slidably connected to the guide groove 20. During operation, when the first wire bundle block 32 and the second wire bundle block 33 are pushed from the discharge port 11 onto the L-shaped guide plate 18, they directly fit against the pusher block 26. At this time, the second motor 24 starts and drives the lead screw 23 to rotate forward, causing the two threaded sleeves 25 to slide relative to each other. This causes the two pusher blocks 26 to drive the first wire bundle block 32 and the second wire bundle block 33 to slide relative to each other until they fit and lock. After that, the second motor 24 drives the lead screw 23 to rotate in reverse, causing the two pusher blocks 26 to quickly reset and prepare for the next push.

[0026] Two threaded sleeves 25 are fixedly connected to opposite sides of a fixed sleeve 28. A limiting element 29 is slidably connected within the inner cavity of the fixed sleeve 28. The limiting element 29 consists of a limiting block and two limiting rods. The top of each limiting rod extends above the guide groove 20 and is fixedly connected to a stop block 31. The stop block 31 has a trapezoidal cross-section. Springs 30 are fitted onto the outer sides of both limiting rods and are positioned between the limiting block and the inner cavity of the fixed sleeve 28. During operation, when the two pusher blocks 26 slide relative to each other, the stop block 31 slides against the L-shaped guide plate 18, and the springs 30 are compressed. When the stop block 31 slides to the opening of the guide groove 20, the stop block 31 is compressed by the springs. The spring 30 slides down onto the L-shaped guide plate 18 under the elastic force, causing the inclined surface of the stop block 31 to fit against the L-shaped guide plate 18. At this time, the top of the stop block 31 no longer blocks the first wire harness block 32 or the second wire harness block 33. After that, the first wire harness block 32 and the second wire harness block 33 fit and lock together. When the two push blocks 26 are reset, the inclined surface of the stop block 31 slides upward again under the pressure of the L-shaped guide plate 18 and slides onto the L-shaped guide plate 18. At this time, the first spring 30 is compressed again. By setting the stop block 31, the first wire harness block 32 and the second wire harness block 33 that slide into the push block 26 can be limited, preventing the first wire harness block 32 and the second wire harness block 33 from detaching from the push block 26 during the movement.

[0027] A lock cylinder 34, hook-shaped, is fixedly connected to the side of cable bundle 1 32 close to cable bundle 2 33. Cable bundle 2 33 has a slot 35 on the side close to cable bundle 1 32, and a storage groove 36 at the bottom of the slot 35. A fixing sleeve 2 38 is located inside the storage groove 36. A locking block 40 is slidably connected to the inner cavity of the fixing sleeve 2 38. One end of the locking block 40 extends to the outside of the fixing sleeve 2 38 and is adapted to the lock cylinder 34. A spring 2 39 is fixedly connected between the locking block 40 and the inner cavity of the fixing sleeve 2 38. During operation... When the first wire harness block 32 and the second wire harness block 33 are pushed and fitted together by the pusher block 26, the lock cylinder 34 on the first wire harness block 32 slides into the slot 35 of the second wire harness block 33. During this process, the lock cylinder 34 first contacts and presses the locking block 40, causing the locking block 40 to slide into the second fixed sleeve 38 and compress the second spring 39 until the lock cylinder 34 slides away from the locking block 40. Under the elastic force of the second spring 39, the locking block 40 pops out and locks the lock cylinder 34, thereby locking the first wire harness block 32 and the second wire harness block 33.

[0028] One side of the cable bundle 33 is provided with a screw hole 37, which is connected to the storage groove 36. A bolt 41 is threaded into the screw hole 37, and one end of the bolt 41 extends into the storage groove 36 and is rotatably connected to the outer wall of the fixing sleeve 38. During operation, when the operator needs to disassemble the cable bundle 32 and the cable bundle 33 after the cable is laid out, the fixing sleeve 38 can be slid in the storage groove 36 by rotating the screw outward, so that the locking block 40 slides and disengages from the lock cylinder 34, thereby facilitating the operator to disassemble and separate the cable bundle 32 and the cable bundle 33.

[0029] The cable guiding mechanism includes a mounting frame 2, support rods 3, guide block 1 4, and guide block 2 6. The mounting frame 2 is fixed to the side of the cable feeding frame 1 near the feed cylinder 8. Two support rods 3 are fixed to the mounting frame 2, which are arranged vertically. Several guide blocks 1 4 are slidably connected to the outer side of each of the two support rods 3. A connecting rod 5 is fixed to the middle of each of the two support rods 3. The end of the connecting rod 5 away from the support rod 3 is fixed to the guide block 2 6. During operation, a single cable can be guided first through guide block 1 4, which facilitates the guidance of multiple cables to guide block 2 6. Half of the cables on the cable feeding frame 1 can be guided in a concentrated manner through guide block 2 6, which facilitates their subsequent movement to guide block 3 21.

[0030] A baffle 2 19 is fixedly connected to the side of the feed cylinder 8 near the pusher block 26, and a baffle 3 27 is fixedly connected to the side of the L-shaped guide plate 18 near the feed cylinder 8. During operation, the baffle 2 19 can prevent the pusher block 26 from sliding off one side of the pusher block 26 during the pushing process of the wire harness block 1 32 and the wire harness block 2 33. The baffle 3 27 can block the outlet 11 during the pushing process of the pusher block 26, preventing the wire harness block 1 32 and the wire harness block 2 33 from accidentally sliding out of the outlet 11 during the pushing process, which would make it difficult for the pusher block 26 to reset.

[0031] A method for laying photovoltaic DC cables using a cable laying device, applicable to the aforementioned photovoltaic DC cable laying device, comprising the following steps: S1: The wire feeding roller 42 on the wire feeding frame 1 rotates to start feeding the wire. The staff first pulls the ends of multiple cables and passes them through the cable guiding mechanism and guide block 3 21 in sequence. S2: Place the two storage boxes 14 into the two feed cylinders 8 respectively and pull out the bottom plate 17. After several wire bundles 1 32 and wire bundles 2 33 enter the two feed cylinders 8 respectively, slide the two storage boxes 14 out and start the motor 1 9 so that several wire bundles 1 32 and wire bundles 2 33 are pushed one by one by the feeding auger 10 onto the L-shaped guide plate 18. S3: Start motor 24. Through the cooperation of thread sleeve 25 and threaded rod 23, the two push blocks 26 slide relative to each other, and drive wire harness block 1 32 and wire harness block 2 33 to slide relative to each other until they are locked together, thus completing the locking and fixing of multiple cables. After that, the cables are fixed again at intervals.

[0032] Working principle: The wire feeding roller 42 on the wire feeding frame 1 rotates to start feeding the wire. The operator first pulls the ends of multiple cables and passes them through the cable guiding mechanism and guide block 21 in sequence. Then, the two storage boxes 14 are placed into the two feeding cylinders 8 respectively. After several bundled wire blocks 32 and 33 have entered the two feeding cylinders 8, the two storage boxes 14 are pulled out. The motor 9 is started, which drives the feeding auger 10 to rotate. This causes the bundled wire blocks 32 and 33 to be pushed one by one onto the L-shaped guide plate 18 by the feeding auger 10. The pushing mechanism on the two L-shaped guide plates 18 can push the bundled wire blocks 32 and 33 to the guide block 21. After the bundled wire blocks 32 and 33 are locked together, the wire feeding mechanism can be used to feed the wires. To secure multiple cables, a baffle 12 on one side of the feed cylinder 8 allows workers to place one end of the storage box 14, filled with cable bundles 32 or 33, into the baffle 12 for positioning. This facilitates the accurate placement of the cable bundles 32 and 33 between the blades of the feed auger 10 after the storage box 14 is removed. When the motor 9 starts, the feed auger 10 pushes the cable bundles 32 or 33 out from the discharge port 11 and onto the L-shaped guide plate 18. The inner side of the discharge port 11 has a chamfer to facilitate the transition of the cable bundles 32 and 33 from the feed auger 10 to the discharge port 11. One side of the inner wall of the 8 has an arc surface to facilitate the fitting of wire harness block 1 32 and wire harness block 2 33. The operator can first insert the base plate 17 along the through groove 2 16 into the lower part of the storage box 14 until it fits against the groove 15. Then, several wire harness blocks 1 32 or wire harness blocks 2 33 are placed one by one into the placement groove of the storage box 14. Next, the storage box 14 is slid down from above the feeding cylinder 8, while simultaneously allowing one end of the storage box 14 to fit against the inner side of the baffle 12, until the hanging ear on the storage box 14 contacts the top of the feeding cylinder 8. At this point, the through groove 2 16 on the storage box 14 corresponds to the through groove 13 on the feeding cylinder 8. The operator then uses their hand to pull out the base plate 17 through the through groove 13, causing several wire harness blocks 1 32 or wire harness blocks 2 33 inside the storage box 14 to fall out. The material falls between the blades of the feeding auger 10. Then, the worker pulls the storage box 14 out of the feeding cylinder 8 from bottom to top. This process is repeated to fill the wire bundle block 32 and wire bundle block 33. When wire bundle block 32 and wire bundle block 33 are pushed from the outlet 11 onto the L-shaped guide plate 18, they directly contact the pusher block 26. At this time, motor 24 starts, driving the lead screw 23 to rotate forward, causing the two lead sleeves 25 to slide relative to each other. This, in turn, causes the two pusher blocks 26 to respectively drive wire bundle block 32 and wire bundle block 33 to slide relative to each other until they are in contact and locked. Afterward, motor 24 drives the lead screw 23 to rotate in reverse, causing the two pusher blocks 26 to quickly reset, preparing for the next push. When the two pusher blocks 26 slide relative to each other...The stop block 31 slides against the L-shaped guide plate 18, and the spring 30 is compressed. When the stop block 31 slides to the opening of the guide groove 20, it slides down the L-shaped guide plate 18 under the elastic force of the spring 30, causing the inclined surface of the stop block 31 to fit against the L-shaped guide plate 18. At this time, the top of the stop block 31 no longer obstructs the first wire harness block 32 or the second wire harness block 33. After that, the first wire harness block 32 and the second wire harness block 33 are locked together. When the two pusher blocks 26 are reset, the stop block... The inclined surface of block 31 slides upward again under the pressure of the L-shaped guide plate 18 and slides onto the L-shaped guide plate 18. At this time, spring 30 is compressed again. The stop block 31 can limit the wire harness block 32 and wire harness block 33 that slide into the pusher block 26, preventing them from detaching from the pusher block 26 during movement. After the wire harness block 32 and wire harness block 33 are pushed and pressed together by the pusher block 26, the lock cylinder 34 on the wire harness block 32 slides into the wire harness block 26. In the process of locking the slot 35 of wire block 2 33, the lock cylinder 34 first contacts and presses the locking block 40, causing the locking block 40 to slide into the fixed sleeve 2 38 and compress the spring 2 39 until the lock cylinder 34 slides away from the locking block 40. Under the elastic force of the spring 2 39, the locking block 40 pops out and locks the lock cylinder 34, thereby locking the wire bundle block 1 32 and the wire bundle block 2 33. When the staff finishes laying the wire and needs to disassemble the wire bundle block 1 32 and the wire bundle block 2 33, Rotating the screw outwards causes the fixing sleeve 38 to slide within the receiving slot 36, allowing the locking block 40 to slide and disengage from the lock cylinder 34. This facilitates the disassembly and separation of the cable bundle block 32 and the cable bundle block 33. The guide block 4 guides a single cable, facilitating the movement of multiple cables towards the guide block 6. The guide block 6 then guides half of the cables on the cable tray 1, enabling subsequent movement towards the guide block 21.
