[0001] This utility model belongs to the field of cable winding and laying technology, specifically, it relates to a cable winding and laying device for wind power new energy construction. Background Technology

[0002] Wind power is a renewable energy source that uses wind turbines to convert the kinetic energy of wind into electrical energy. It has advantages such as being pollution-free, low-carbon, and energy-efficient, and is of great significance for reducing fossil fuel consumption, lowering greenhouse gas emissions, and improving the energy structure.

[0003] In wind power construction, cables play a crucial role. They are responsible for transmitting electricity and ensuring that wind energy is effectively transmitted to the power grid after being converted into electrical energy. During the cable laying process, cable winding and unwinding devices are usually used to improve construction efficiency and ensure the safety and reliability of the cables.

[0004] Patent CN220449374U discloses a cable rewinder that requires little effort from the operator, saving time and effort while increasing work efficiency. However, manual disassembly can easily damage the device. Although the device can rewind cables, after the first motor stops running, the rewinding roller rotates because it lacks a fixing mechanism. This rotation causes the cable to fall off the roller, requiring rewinding and reducing work efficiency. Utility Model Content

[0005] To address the technical problem of cables falling off the winding roller and requiring rewinding, which reduces work efficiency, this utility model provides a cable winding and unwinding device for wind power new energy construction.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A cable winding and unwinding device for wind power new energy construction includes a base plate; a winding roller disposed above the base plate; first upright plates connected to the upper surface of the base plate at positions corresponding to both ends of the winding roller, with both ends of the winding roller connected to the first upright plates via bearings; a ratchet is connected to one end of the winding roller, and a pawl is rotatably connected to one of the first upright plates at a position corresponding to the ratchet, with the ratchet and pawl engaging; a fixing plate is connected to one of the first upright plates at a position below the ratchet near the ratchet, with a first spring connecting the fixing plate and the pawl; and a housing is connected to one of the first upright plates at a position corresponding to the pawl, with a first storage groove formed near the pawl on the housing, a first stop slidably connected within the first storage groove, and a second spring connecting the first stop and the housing.

[0008] Preferably, a second storage groove is provided below the end of the first stop block away from the pawl, a second stop block is slidably connected in the second storage groove, and a plurality of third springs are connected between the second stop block and the first stop block.

[0009] Preferably, a limiting groove is provided on the outer shell corresponding to the position of the second stop, and the second stop is slidably connected in the limiting groove.

[0010] Preferably, a first lever is connected above one side of the second stop, and a movable groove is provided on the outer shell and the first stop corresponding to the position of the first lever. The first lever is slidably connected in the movable groove, and a sliding groove is provided on the outer shell corresponding to the position of the first lever. The first lever and the sliding groove are slidably engaged.

[0011] Preferably, a second lever is connected to the end of the ratchet near the pawl and the side away from one of the first uprights.

[0012] Preferably, a first sprocket is connected to the end of the take-up roller away from the ratchet, and a second sprocket is provided at the position of the first sprocket in the middle of the upper part of the base plate. A chain meshes with the outer side of the first sprocket and the second sprocket. A reciprocating screw is connected to the side of the second sprocket near the take-up roller. A second vertical plate is connected to the two ends of the reciprocating screw on the upper surface of the base plate respectively. The reciprocating screw is connected to the second vertical plate through bearings.

[0013] Preferably, a movable rod is threadedly connected to the outer side of the reciprocating screw, and a U-shaped movable frame is connected to the upper end of the movable rod. Symmetrically arranged rotating rods are rotatably connected inside the movable frame.

[0014] Preferably, the lower end of the moving rod is connected to a slider, and symmetrically arranged slide rails are connected between the second upright plates at the positions corresponding to the slider, with the slider slidably connected within the slide rails.

[0015] Preferably, a motor is connected to the side of the first sprocket away from the take-up roller, and an L-shaped mounting base is connected to the other first vertical plate corresponding to the position of the motor, with the motor fixed to the mounting base.

[0016] Preferably, a third vertical plate is symmetrically arranged on the upper surface of the base plate at a position away from the first vertical plate, and a rotating roller and a limiting roller are respectively connected above the third vertical plate.

[0017] The beneficial effects of this utility model are:

[0018] By starting the motor, the take-up roller rotates. With the cooperation of the ratchet and pawl, the take-up roller can only rotate in one direction. This ensures the cable remains flat after winding and when the motor stops, preventing the take-up roller from deflecting and causing the cable to fall off, eliminating the need for rewinding and improving efficiency. To unwind the cable, the second lever is moved downwards, moving the pawl away from the ratchet and positioning it below the first stop. Moving the second lever upwards then moves the first lever, causing it to drive the second stop into the second receiving slot. When the first lever rises to the position corresponding to the slide groove, the second spring's restoring force will drive the first stop. Slide the cable out of the first storage slot and position it above the pawl. Release the second lever, and the pawl will be blocked by the first stop, preventing it from resetting and engaging with the ratchet. At this point, rotate the take-up roller in the opposite direction to unwind the cable. The operation is simple and convenient. When you need to rewind the cable, hold the second lever and pull the first lever to make the first stop enter the first storage slot. When the first lever moves to the position corresponding to the movable slot, the second stop will slide into the slide groove under the action of the third spring's restoring force, and the first lever will slide into the movable slot, fixing the first stop. After the first stop is fixed, slowly release the second lever to make the pawl engage with the ratchet, and the cable can be rewound, thus preventing the take-up roller from deflecting.

[0019] During the rotation of the motor, the first sprocket will rotate, which, with the help of the chain, will drive the second sprocket to rotate. The rotation of the second sprocket will drive the reciprocating screw to rotate. During the rotation of the reciprocating screw, the moving rod and the moving frame will move back and forth on the outside of the reciprocating screw. The cable is located between the two rotating rods. Therefore, during the winding of the cable, the moving rod and the moving frame will drive the cable to move back and forth within the range of the winding roller, so that the cable can be evenly wound on the winding roller, so that the cable can be wound flat.

[0035] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 - Figure 5 As shown, a cable winding and unwinding device for wind power new energy construction includes a base plate 1, and a winding roller 11 is arranged above the base plate 1 for winding the cable.

[0037] The upper surface of the base plate 1 is connected to the first vertical plate 12 at the positions corresponding to the two ends of the take-up roller 11. The two ends of the take-up roller 11 are connected to the first vertical plate 12 through bearings.

[0038] One end of the take-up roller 11 is connected to a ratchet 5, and a first vertical plate 12 is rotatably connected to a pawl 51 corresponding to the position of the ratchet 5. The ratchet 5 and the pawl 51 mesh, and the cooperation between the ratchet 5 and the pawl 51 can prevent the take-up roller 11 from reversing when taking up the cable.

[0039] One of the first upright plates 12 is connected to a fixed plate 53 at the position below the ratchet 5 near the end of the pawl 51. A first spring 52 is connected between the fixed plate 53 and the pawl 51. The first spring 52 is used to reset the pawl 51.

[0040] One of the first upright plates 12 is connected to the outer shell 6 at the position corresponding to the pawl 51. The outer shell 6 has a first storage groove 61 near the pawl 51. A first stop 62 is slidably connected in the first storage groove 61. The first stop 62 is used to block the pawl 51.

[0041] A second spring 63 is connected between the first stop block 62 and the outer casing 6. The second spring 63 is used to reset the first stop block 62.

[0042] A second storage groove 64 is provided below the end of the first stop block 62 away from the pawl 51. A second stop block 65 is slidably connected in the second storage groove 64. The second stop block 65 is used to block the first stop block 62.

[0043] A plurality of third springs 66 are connected between the second stop 65 and the first stop 62. The third springs 66 are used to reset the second stop 65.

[0044] The outer casing 6 has a limiting groove 67 at the position corresponding to the second stop 65. The second stop 65 is slidably connected in the limiting groove 67. The limiting groove 67, in conjunction with the second stop 65, can limit the position of the first stop 62.

[0045] A first lever 7 is connected to the upper side of the second stop 65. The outer shell 6 and the first stop 62 are provided with a movable groove 71 corresponding to the position of the first lever 7. The first lever 7 is slidably connected in the movable groove 71. Through the cooperation of the first lever 7 and the movable groove 71, the second slide can be sent into the second storage groove 64.

[0046] The outer casing 6 has a groove 72 at the position corresponding to the first lever 7. The first lever 7 slides in the groove 72. Through the cooperation between the groove 72 and the first lever 7, the first stop 62 can slide out of the first storage slot 61 or be sent into the first storage slot 61.

[0047] A second lever 73 is connected to one end of the ratchet 5 near the pawl 51 and away from one of the first upright plates 12. The second lever 73 is used to move the pawl 51 to a position away from the ratchet 5.

[0048] In practical use, by starting the motor 23, the motor 23 drives the take-up roller 11 to rotate. With the cooperation of the ratchet 5 and the pawl 51, the take-up roller 11 can only rotate in one direction. Thus, after the cable is wound up and the motor 23 stops running, the cable can be kept flat, and the cable is prevented from deflecting and falling off the take-up roller 11. The cable does not need to be wound up again, which improves efficiency.

[0049] When it is necessary to unload the cable from the take-up roller 11, move the second lever 73 downward to move the pawl 51 away from the ratchet 5 and position the pawl 51 below the first stop block 62. After moving the lever, move the first lever 7 upward to move the first lever 7 to drive the second stop block 65 into the second storage groove 64. When the first lever 7 rises to the position corresponding to the slide groove 72, under the action of the restoring force of the second spring 63, it will drive the first stop block 62 to slide out of the first storage groove 61 and be above the pawl 51. Release the second lever 73, and the pawl 51 will be blocked by the first stop block 62 and will not be able to reset and engage with the ratchet 5. At this time, rotate the take-up roller 11 in the opposite direction to unload the cable. The operation is simple and convenient.

[0050] When the cable needs to be wound up, hold the second lever 73 and pull the first lever 7 so that the first stop 62 enters the first storage groove 61. When the first lever 7 moves to the position corresponding to the movable groove 71, under the action of the restoring force of the third spring 66, the second stop 65 will slide into the slide groove 72, and the first lever 7 will slide into the movable groove 71, so that the first stop 62 is fixed. After the first stop 62 is fixed, slowly release the second lever 73 so that the pawl 51 engages with the ratchet 5, and the cable can be wound up, thereby preventing the winding roller 11 from deflecting.

[0051] The take-up roller 11 is connected to a first sprocket 2 at the end away from the ratchet 5. A second sprocket 21 is set at the middle of the upper part of the base plate 1, corresponding to the position of the first sprocket 2. A chain 22 is engaged on the outer side of the first sprocket 2 and the second sprocket 21. Through the cooperation of the first sprocket 2, the second sprocket 21 and the chain 22, the take-up roller 11 and the reciprocating screw 3 can be driven to rotate synchronously.

[0052] A motor 23 is connected to the side of the first sprocket 2 away from the take-up roller 11. The motor 23 is used to drive the first sprocket 2 to rotate.

[0053] Another first upright plate 12 is connected to an L-shaped mounting base 24 at the position corresponding to the motor 23. The motor 23 is fixed on the mounting base 24, which is used to install and fix the motor 23.

[0054] The second sprocket 21 is connected to a reciprocating screw 3 on the side near the take-up roller 11. The reciprocating screw 3 is used to drive the moving rod 32 to perform reciprocating motion.

[0055] The upper surface of the base plate 1 is connected to the two ends of the reciprocating screw 3 respectively. The reciprocating screw 3 is connected to the second vertical plate 31 through bearings. The second vertical plate 31 is used to support the reciprocating screw 3.

[0056] A movable rod 32 is threadedly connected to the outer side of the reciprocating screw 3. A U-shaped movable frame 33 is connected to the upper end of the movable rod 32. A symmetrically arranged rotating rod 34 is rotatably connected inside the movable frame 33. The position of the cable can be limited by the cooperation between the movable frame 33 and the rotating rod 34. The rotation of the rotating rod 34 can assist the take-up roller 11 in winding or unwinding the cable.

[0057] The lower end of the moving rod 32 is connected to a slider 35. The second vertical plate 31 is connected to the position of the slider 35 by symmetrically arranged slide rails 36. The slider 35 is slidably connected in the slide rail 36. Through the cooperation of the slider 35 and the slide rail 36, the position of the moving rod 32 can be limited to prevent the moving rod 32 from deflecting during the movement.

[0058] In practical use, when the motor 23 rotates, it drives the first sprocket 2 to rotate. With the cooperation of the chain 22, it drives the second sprocket 21 to rotate. The rotation of the second sprocket 21 drives the reciprocating screw 3 to rotate. When the reciprocating screw 3 rotates, it drives the moving rod 32 and the moving frame 33 to move back and forth outside the reciprocating screw 3. The cable is located between the two rotating rods 34. Thus, during the winding of the cable, the moving rod 32 and the moving frame 33 drive the cable to move back and forth within the range of the winding roller 11, so that the cable can be evenly wound on the winding roller 11, and the cable can be wound flat.

[0059] A third vertical plate 4 is symmetrically arranged on the upper surface of the base plate 1 at a position away from the first vertical plate 12. A rotating roller 41 and a limiting roller 42 are respectively connected above the third vertical plate 4. The limiting roller 42 is located above the rotating roller 41. The rotating roller 41 is used to reset the winding roller 11 to wind or unwind the cable. The limiting roller 42 is used to limit the position of the cable so that the cable is always in the position between the rotating roller 41 and the limiting roller 42, preventing the cable from moving randomly.
