Description

Technical Field

[0001] This utility model relates to the technical field of line fault indicators, specifically an indicator for segmented location of line faults in wind farms. Background Technology

[0002] Due to the harsh working environment of wind farms, most of the lines are exposed to the elements for a long time, making them susceptible to natural disasters such as strong winds, rain, and lightning, as well as damage from external forces such as birds, trees, motor vehicles, and theft. This results in a high rate of electrical faults in the lines. In addition, the power grid structure of wind farms is complex and the distribution lines are long. In order to facilitate the quick identification of faulty lines, fault indicators are often installed in sections along the lines to help staff conduct troubleshooting.

[0003] However, existing line fault indicators require workers to tighten multiple bolts individually to secure them to the outside of the cable. This tightening of the bolts until they are close to the cable is necessary for installation and fixation. Furthermore, after installation, the indicators are prone to shaking or even falling off and being damaged due to loose bolts, reducing the practicality of the device. Therefore, this paper proposes an indicator for segmented location of line faults in wind farms to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An indicator for segmented fault location in wind farm lines, as described in this utility model, includes an indicator body. A frame is fixedly connected to the outer side of the indicator body. A clamping plate is slidably connected to the inner side of the frame. A connecting plate is fixedly connected to the outer side of the clamping plate. A threaded screw with both positive and negative threads is threaded to the inner side of one side of the connecting plate. The threaded screw with both positive and negative threads is rotatably connected to the frame. A ratchet is fixedly connected to the outer side of the threaded screw with both positive and negative threads. A pawl is rotatably connected to the outer side of the frame. A torsion spring is fixedly connected to the outer side of the frame. One end of the torsion spring is fixedly connected to the pawl. This step, by setting the clamping plate, threaded screw with both positive and negative threads, ratchet, and pawl, ensures that during device installation... The clamps are placed on the outside of the cable, and then the forward and reverse threaded screws are rotated. The forward and reverse threaded screws cause the clamps to move closer together, thus clamping and fixing the cable. Then, the indicator body is connected to the cable. While the forward and reverse threaded screws are rotating, they also drive the ratchet to rotate in the forward direction, so that the pawl does not restrict the rotation of the ratchet. After fixing, the pawl restricts the ratchet, so that if the device is subjected to vibration and is about to loosen, the pawl limits the ratchet to prevent it from rotating in the reverse direction. This prevents the forward and reverse threaded screws from rotating in the reverse direction, making it difficult for the clamps to move away from each other due to the reverse rotation of the forward and reverse threaded screws, thus improving the stability of the device's clamping and fixing.

[0006] Preferably, a fixing plate is fixedly connected to the outer side of the frame, a magnetic rod is slidably connected to the inner side of the fixing plate, and a connecting block is fixedly connected to the outer side of the pawl. A slot is formed on the surface of the connecting block, and the magnetic rod and the slot are used in conjunction. By setting up the fixing plate, magnetic rod, connecting block, and slot, after the device is installed, the magnetic rod can be pulled to insert into the inner side of the slot. The magnetic rod is attracted to the inner side of the fixing plate and the slot, thereby further restricting the position of the connecting block, making the restriction of the ratchet on the ratchet more stable, making the installation of the device more stable, and improving the stability of the device.

[0007] Preferably, a limiting rod is slidably connected to the inner side of one side of the connecting plate, and the limiting rod is fixedly connected to the frame; this step, by setting the limiting rod, further restricts the movement trajectory of the connecting plate and the clamping plate in conjunction with the positive and negative threaded screws, making the clamping plate less prone to shaking and improving the stability of the device operation.

[0008] Preferably, the clamping plate has multiple rods fixedly connected to its outer side, a round rod slidably connected to the outer side of the multiple rods, a limit frame slidably connected to the outer side of the round rod, the limit frame and the frame being fixedly connected, and a reinforcing plate fixedly connected to the outer side of the round rod, the reinforcing plate and the frame being slidably connected. This step, by setting up multiple rods, a round rod, a limit frame, and a reinforcing plate, ensures that when the clamping plate moves, it drives the multiple rods to move, which in turn drives the round rod and the reinforcing plate to move. The limit frame guides the round rod, causing it to press down on the reinforcing plate, which then adheres tightly to the cable. This, in conjunction with the clamping plate, further clamps and secures the cable, improving the stability of the device installation.

[0009] Preferably, a limiting plate is fixedly connected to the inner side of the frame, and the limiting plate and the reinforcing plate are slidably connected. This step, by setting the limiting plate, allows the plane of the limiting plate to adhere to the inner wall of the reinforcing plate when it moves, thereby further restricting the movement of the reinforcing plate, making it less prone to shaking, and improving the stability of the device operation.

[0010] Preferably, a connecting screw is fixedly connected to the outer side of the magnetic rod, and a retaining plate is threadedly connected to the outer side of the connecting screw. By setting the connecting screw and the retaining plate, after the magnetic rod is inserted into the inner side of the connecting block, the retaining plate can be screwed to the outer side of the connecting screw. Thus, the retaining plate, in conjunction with the protrusion of the magnetic rod itself, further restricts the position of the magnetic rod, making the restriction of the magnetic rod on the connecting block more stable and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up clamping plates, positive and negative threaded screws, ratchet, and pawl, allows the clamping plates to be placed on the outside of the cable during installation. Then, the positive and negative threaded screws are rotated, causing the clamping plates to move closer together, thereby clamping and fixing the cable. The indicator body is then connected to the cable. As the positive and negative threaded screws rotate, they also drive the ratchet to rotate in the forward direction, preventing the pawl from restricting the ratchet's rotation. After fixing, the pawl restricts the ratchet, preventing it from rotating in the reverse direction if the device is about to loosen due to vibration. This, in turn, prevents the positive and negative threaded screws from rotating in the reverse direction, making it difficult for the clamping plates to move away from each other due to the reverse rotation of the positive and negative threaded screws, thus improving the stability of the clamping and fixing of the device.

[0013] 2. By setting up a fixing plate, a magnetic rod, a connecting block, and a slot, this utility model allows the magnetic rod to be pulled into the slot after the device is installed. The magnetic rod is attracted to the fixing plate and the slot, thereby further restricting the position of the connecting block, making the ratchet's restriction on the ratchet more stable, making the installation of the device more stable, and improving the stability of the device.

[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, an indicator for segmented fault location in wind farm lines includes an indicator body 1. A frame 2 is fixedly connected to the outer side of the indicator body 1. A clamping plate 3 is slidably connected to the inner side of the frame 2. A connecting plate 4 is fixedly connected to the outer side of the clamping plate 3. A threaded screw 5 with both positive and negative threads is threaded to the inner side of one side of the connecting plate 4. The threaded screw 5 is rotatably connected to the frame 2. A ratchet 6 is fixedly connected to the outer side of the threaded screw 5. A pawl 7 is rotatably connected to the outer side of the frame 2. A torsion spring 8 is fixedly connected to the outer side of the frame 2. One end of the torsion spring 8 is fixedly connected to the pawl 7. This step, by setting up the clamping plate 3, the threaded screw 5, the ratchet 6, and the pawl 7, ensures that during device installation, the clamping plate 3 is fitted over the outside of the cable. Then, rotate the screw 5 (both positive and negative threads), causing the clamping plates 3 to move closer together, thus clamping and fixing the cable. Then, connect the indicator body 1 to the cable. While the screw 5 is rotating, it also drives the ratchet 6 to rotate in the forward direction, so that the pawl 7 does not restrict the rotation of the ratchet 6. After fixing, the pawl 7 restricts the ratchet 6, so that if the device is about to loosen due to vibration, the pawl 7 limits the ratchet 6, preventing it from rotating in the reverse direction. This prevents the screw 5 from rotating in the reverse direction, making it difficult for the clamping plates 3 to move away from each other due to the reverse rotation of the screw 5, thus improving the stability of the device clamping and fixing.

[0024] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, a fixing plate 9 is fixedly connected to the outer side of the frame 2, and a magnetic rod 10 is slidably connected to the inner side of the fixing plate 9. A connecting block 11 is fixedly connected to the outer side of the pawl 7, and a slot 12 is provided on the surface of the connecting block 11. The magnetic rod 10 and the slot 12 are used in conjunction. By setting up the fixing plate 9, magnetic rod 10, connecting block 11 and slot 12, after the device is installed, the magnetic rod 10 can be pulled to insert into the inner side of the slot 12. The magnetic rod 10 is attracted to the inner side of the fixing plate 9 and the slot 12, thereby further restricting the position of the connecting block 11, making the restriction of the ratchet 7 on the ratchet 6 more stable, making the installation of the device more stable, and improving the stability of the device.

[0025] Furthermore, such as Figure 3 As shown, a limiting rod 13 is slidably connected to the inner side of the connecting plate 4 on one side, and the limiting rod 13 is fixedly connected to the frame 2. This step, by setting the limiting rod 13, further restricts the movement trajectory of the connecting plate 4 and the clamping plate 3 in conjunction with the positive and negative thread screws 5, making the clamping plate 3 less prone to shaking and improving the stability of the device operation.

[0026] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, a multi-section rod 14 is fixedly connected to the outside of the clamping plate 3. A round rod 15 is slidably connected to the outside of the multi-section rod 14. A limit frame 16 is slidably connected to the outside of the round rod 15. The limit frame 16 is fixedly connected to the frame 2. A reinforcing plate 17 is fixedly connected to the outside of the round rod 15. The reinforcing plate 17 is slidably connected to the frame 2. This step, by setting up the multi-section rod 14, round rod 15, limit frame 16, and reinforcing plate 17, will drive the multi-section rod 14 to move when the clamping plate 3 moves. The multi-section rod 14 will drive the round rod 15 and the reinforcing plate 17 to move. The limit frame 16 will guide the round rod 15, causing the round rod 15 to drive the reinforcing plate 17 to press down. The reinforcing plate 17 will then be pressed tightly against the cable, thereby cooperating with the clamping plate 3 to further clamp and fix the cable, improving the stability of the device installation.

[0027] Furthermore, such as Figure 2 As shown, a limiting plate 18 is fixedly connected to the inner side of the frame 2, and the limiting plate 18 and the reinforcing plate 17 are slidably connected. This step, by setting the limiting plate 18, allows the reinforcing plate 17 to move, and the plane of the limiting plate 18 is pressed against the inner wall of the reinforcing plate 17, thereby further restricting the movement of the reinforcing plate 17, making it less prone to shaking, and improving the stability of the device operation.

[0028] Furthermore, such as Figure 4As shown, a connecting screw 19 is fixedly connected to the outer side of the magnetic rod 10, and a retaining plate 20 is threadedly connected to the outer side of the connecting screw 19. By setting the connecting screw 19 and the retaining plate 20, after the magnetic rod 10 is inserted into the inner side of the connecting block 11, the retaining plate 20 can be screwed to the outer side of the connecting screw 19. Thus, the retaining plate 20, in conjunction with the protrusion of the magnetic rod 10 itself, further restricts the position of the magnetic rod 10, making the restriction of the magnetic rod 10 on the connecting block 11 more stable and improving the stability of the device.

[0029] Working principle: During device installation, clamp plate 3 is placed on the outside of the cable. Then, the threaded screw 5 is rotated, causing clamp plates 3 to move closer together. Simultaneously, as clamp plates 3 move, multi-section rod 14 moves, which in turn moves round rod 15 and reinforcing plate 17. The limiting frame 16 guides round rod 15, causing it to press down on reinforcing plate 17, which then presses tightly against the cable. This, in conjunction with clamp plate 3, clamps and secures the cable. Then, the indicator body 1 is connected to the cable. Simultaneously, the rotation of threaded screw 5 drives ratchet 6 to rotate forward, causing… The pawl 7 does not restrict the rotation of the ratchet 6. After fixing, the magnetic rod 10 is pulled and inserted into the inside of the slot 12. The magnetic rod 10 is attracted to the fixing plate 9 and the inside of the slot 12, thereby further restricting the position of the connecting block 11. The connecting block 11 restricts the pawl 7, and then the pawl 7 further restricts the ratchet 6. When the device is vibrating and is about to loosen, the pawl 7 limits the ratchet 6, preventing the ratchet 6 from rotating in the opposite direction. This prevents the screws 5 from rotating in the opposite direction, making it difficult for the clamping plates 3 to move away from each other due to the opposite rotation of the screws 5, thus making the installation of the device more stable.
