Description

Technical Field

[0001] The present invention relates to the technical field of cable installation, and in particular to an installation device for a high-voltage power supply cable. Background Art

[0002] Installation devices for high-voltage power cables are widely used in power systems, such as substations and power plants. They ensure the safe and accurate installation of high-voltage cables, improving the stability and reliability of power systems. These devices also offer advantages such as compact structure, high integration, and portability, making them easy to carry and transport, meeting installation requirements in diverse scenarios.

[0003] Chinese invention patent application number 201410371896.4 proposes a cross-road installation tool and method for high-voltage transmission and distribution cables. The tool includes a wire tensioning device, a pay-off tensioning mechanism, a quick-draw mechanism, a lead wire ray device, a cable traction rope, and at least two cable racks. The lead wire and cable traction rope are connected to the cable via a mouse-shaped connector. The cable racks include a base, a vertical pole, and a crossbar. Using this tool reduces the time required by conventional tools by one-quarter and requires only two operators, compared to at least five. More importantly, the lead wire, traction rope, and cable remain suspended in the air, effectively preventing road transport.

[0004] However, in this technical solution, when the cable is installed and in a suspended state, the position of the cable outlet will keep changing when the cable is unwound, causing the cable to swing, thereby causing the installation mechanism to shake or even fall, resulting in the cable being unstable and falling, affecting the cable installation efficiency; at the same time, the cable is not tightened when it is installed and transported to the top of the tower, and is in a loose state. At this time, if there is wind passing by, the cable will also swing and become unstable; in addition, the cable is generally stored in a coil, and when it is pulled out from the cable reel, the cable will bend due to long-term coiling and storage. The machine can only tension and straighten the cable after it is installed, and it takes a long time to adjust the tension, affecting the installation efficiency.

[0005] Therefore, it is necessary to solve the above problems by using an installation device for high-voltage power supply cables. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] In order to solve the problem that the position of the cable outlet changes constantly when the cable is unwound, causing the cable to swing, thereby causing the cable to be unstable and fall, affecting the installation efficiency of the cable, and the problem that the cable is not tightened when it is installed and transported to the top of the tower, and is in a loose state. At this time, if there is wind passing by, the cable will also swing and become unstable, affecting the installation efficiency, embodiment 1 is proposed. Example

[0028] The present invention provides Figures 1 to 6 The installation device for a high-voltage power supply cable shown in the figure includes a reeling assembly 1, a cable body 2 is wound on the reeling assembly 1, a limiting tube 7 is provided on the reeling assembly 1, a roller 3 is provided on the top of the reeling assembly 1, the limiting tube 7 is obliquely arranged on the cross plate 104, and the end of the limiting tube 7 away from the roller 3 is arranged in a trumpet shape. There are two rollers 3, and they are staggered up and down. The end of the limiting tube 7 close to the roller 3 is arranged between the two rollers 3; a detection assembly 4 is provided on the roller 3, the free end of the cable body 2 passes through the limiting tube 7, and after passing through the detection assembly 4, it is clamped in the clamping assembly 6, and the clamping assembly 6 is arranged on the transport assembly.

[0029] By setting a limiting tube 7, the outgoing direction of the cable body 2 is fixed to prevent the cable body 2 from swinging due to the changing outgoing position when the cable body 2 is pulled out from the roll, thereby causing the cable body 2 to be unstable; by setting a detection component 4, the cable body 2 is clamped and stabilized when it comes out, and by keeping the unwinding speed and the transportation speed synchronized, the cable body 2 is ensured to be in a taut state, and the cable body 2 can be pre-straightened to avoid the cable body 2 being blown by the wind when it is relaxed and causing instability, thereby improving installation efficiency.

[0030] During the process of unwinding the cable body 2, since the cable body 2 is wound on the rotating shaft 102, the position of the cable outlet will keep changing when the cable body 2 is unwound, causing the outlet point of the cable body 2 to move back and forth on the cable reel, further causing the cable body 2 to move back and forth between the rollers 3, causing the detection component 4 to be unable to stably clamp and fix the cable body 2, thereby causing the cable body 2 to be unstable in outlet, affecting the installation efficiency of the cable.

[0031] In order to solve the above technical problems, Figures 1-3 As shown, by setting a limit tube 7 to fix the outlet point of the cable body 2, the auxiliary cable body 2 can stably pass through the detection components 4, ensuring that the detection component 4 is stably clamped and the stability of the cable body 2 outlet. The detection component 4 includes a fixed shaft 401, and the fixed shaft 401 is provided with a plurality of grooves 402 along the circumference. The groove 402 is provided with a detection spring 403, and the end of the detection spring 403 is fixedly provided with a detection plate 404; the detection component 4 is fixedly set in the middle position of the roller 3, and the fixed shaft 401 is fixedly set in the middle of the roller 3. The cable body 2 passes between the detection components 4 on the two rollers 3, and the surface of the cable body 2 contacts the detection plate 404. The distance between the detection components 4 is less than the diameter of the cable body 2, which facilitates the detection plate 404 to clamp the cable body 2.

[0032] During use, the cable body 2 passes through the inside of the limiting tube 7 and then passes between the two detection components 4. The cable body 2 contacts the detection plate 404, causing the detection plate 404 to move toward the groove 402, thereby compressing the detection spring 403. The elastic force of the detection spring 403 pushes the detection plate 404 in the opposite direction to clamp and fix the cable body 2. The detection component 4 cooperates with the limiting tube 7 to fix the cable body 2, prevent the cable body 2 from swinging, and ensure the stability of the cable body 2.

[0033] When the unwinding assembly 1 unwinds the cable body 2 , the cable body 2 passes between the detection plates 404 . The friction between the cable body 2 and the detection plates 404 drives the detection assembly 4 to rotate, thereby driving the roller 3 to rotate.

[0034] When the transport assembly transports the cable body 2 from the ground to the top of the high-voltage line tower, a corresponding clamping mechanism needs to be set up to fix the end of the cable body 2 on the transport assembly to ensure that the cable body 2 can be transported to the top of the high-voltage line tower for installation.

[0035] In order to solve the above technical problems, Figures 4-5As shown, by providing a clamping assembly 6 on the transport assembly, the cable body 2 is fixed to the transport assembly, and the transport assembly then transports the cable body 2 to the top of the high-voltage line tower. The transport assembly includes a drone 501, a support frame 502 is provided parallel to the bottom of the drone 501, and legs 503 are evenly provided on the support frame 502. The clamping assembly 6 is fixedly provided on the legs 503 located in the middle position, and a camera is fixedly provided at the center of the bottom surface of the drone 501. The clamping assembly 6 includes symmetrically arranged fixed blocks 601, and the opposite sides of the fixed blocks 601 are provided as inclined surfaces, so that when the sliders 602 are repelled and moved by the magnetic repulsion force, they will approach each other. When the slider 602 is at the top of the chute 606, the distance between them is the greatest. When the slider 602 is at the bottom of the chute 606, the distance between them is the greatest. A slider 602 is slidably provided on the side opposite the fixed block 601. A chute 606 is provided on the side opposite the fixed block 601. A protrusion is provided on the side of the slider 602 near the fixed block 601, and the protrusion is engaged in the chute 606. A return spring 604 is fixedly provided on the top of the slider 602. An electromagnet 605 is fixedly provided on the end of the return spring 604 away from the slider 602. The slider 602 can be made of a permanent magnet material. When the electromagnet 605 is energized, it can generate magnetic repulsion or magnetic attraction. When the electromagnet 605 is not energized, the slider 602 is at the top of the chute 606, the greatest distance, making it convenient for staff to place the free end of the cable body 2 there. The electromagnet 605 is fixedly provided on the fixed block 601, and a clamping plate 603 is fixedly provided on the side opposite the slider 602.

[0036] During use, the staff on the ground places the end of the cable body 2 between the two clamping plates 603, and then controls the electromagnet 605 to be energized in the forward direction, generating a magnetic repulsive force on the slider 602, so that the slider 602 moves along the slide groove 606 in the direction away from the electromagnet 605 until it moves to the bottom end of the slide groove 606, thereby clamping and fixing the cable body 2.

[0037] Then, the drone 501 is controlled to take off and move toward the top of the high-voltage line tower, thereby driving the free end of the cable body 2 between the clamping plates 603 to move toward the top of the tower. The flight position is monitored by the camera. When it reaches the top of the tower, the drone 501 is controlled to land on the top of the tower.

[0038] At this point, the staff at the top of the tower signal the ground staff to release the clamping assembly 6 from the cable body 2. Specifically, the electromagnet 605 is reversed to generate a magnetic attraction on the slider 602, causing the slider 602 to move along the slide 606 toward the electromagnet 605 until it reaches the top of the slide 606, thereby releasing the clamping of the cable body 2. The staff at the top of the tower then secures the cable body 2 to the installation position at the top of the tower. By setting the clamping assembly 6 to secure the free end of the cable body 2, the auxiliary transport assembly 5 transports the cable body 2 to the top of the high-voltage line tower.

[0039] While the unwinding component 1 is unwinding, the drone 501 is synchronously transported toward the top of the tower. During this process, if the unwinding speed does not match the flight speed of the drone 501, the unwinding speed may be too fast or too slow, resulting in the drone 501 being obstructed in flight or the cable body 2 being loose, thereby affecting the stability of the cable body 2 during transportation.

[0040] In order to solve the above technical problems, Figure 1 and Figure 6 As shown, the unwinding assembly 1 includes parallel vertical plates 101, a rotating shaft 102 is rotatably arranged between the vertical plates 101, one end of the rotating shaft 102 is fixedly connected to the unwinding motor 103, the roller 3 is rotatably arranged on one side of the top of the vertical plate 101, a horizontal plate 104 is fixedly arranged on the side of the vertical plate 101 close to the roller 3, the limiting tube 7 is fixedly arranged at the center position of the horizontal plate 104, and the cable body 2 is wound on the rotating shaft 102.

[0041] Since the height of the high-voltage tower is constant, when transporting the cable body 2, the placement point of the unwinding assembly 1 is selected so that the distance between the unwinding assembly 1 and the bottom of each high-voltage tower where the cable body 2 needs to be transported is basically consistent. Then, through flight transportation tests, it is determined that the unwinding speed is compatible with the flight speed of the drone 501.

[0042] During unwinding, the unwinding motor 103 is controlled to rotate, driving the rotating shaft 102 to rotate, thereby unwinding the cable body 2 wrapped around its outer surface. The cable body 2 passes through the interior of the limiting tube 7 and is discharged. At the same time, the drone 501 drives the cable body 2 through the clamping assembly 6, moving synchronously at a speed compatible with the unwinding speed, and stably transporting the cable body 2 to the top of the tower.

[0043] Since the cable body 2 is coiled and stored, the cable body 2 will be bent after being unwound. When the cable body 2 is in a taut state when unwound, the cable body 2 can also be pre-straightened to reduce the workload of the cable body 2 at the top of the high-voltage line tower.

[0044] By matching the unwinding speed with the flight speed of the drone 501, the cable body 2 is ensured to remain taut during transportation from the ground to the top of the high-voltage line tower, and the cable body 2 can also be pre-straightened; the cable body 2 is prevented from loosening due to unwinding too quickly, causing it to swing in windy weather; the cable body 2 is prevented from being unwound too slowly and becoming too tight, causing the drone 501 to be obstructed in its movement; the workload of the cable body 2 at the top of the tower is reduced, and the installation efficiency of the cable body 2 is ensured.

[0045] The working principle of the present invention is as follows: first, the speed is matched. When transporting the cable body 2, the placement point of the unwinding assembly 1 is selected so that the distance between the unwinding assembly 1 and the bottom of each high-voltage line tower where the cable body 2 needs to be transported is basically consistent. Then, through a flight transportation test, it is determined that the unwinding speed is compatible with the flight speed of the drone 501.

[0046] Secondly, to fix the cable, the staff on the ground places the end of the cable body 2 between the two clamping plates 603, and then controls the electromagnet 605 to be energized in the forward direction to generate a magnetic repulsive force on the slider 602, so that the slider 602 moves along the slide groove 606 in the direction away from the electromagnet 605 until it moves to the bottom end of the slide groove 606, thereby clamping and fixing the cable body 2.

[0047] Then, correct the cable outlet point, and the cable body 2 passes through the inside of the limiting tube 7 and then passes between the two detection components 4. The cable body 2 resists the detection plate 404, causing the detection plate 404 to move toward the groove 402, thereby compressing the detection spring 403. The elastic force of the detection spring 403 pushes the detection plate 404 in the opposite direction to clamp and fix the cable body 2.

[0048] Then, after transporting the cable and fixing the cable body 2, the unwinding motor 103 is controlled to rotate, driving the rotating shaft 102 to rotate, thereby unwinding the cable body 2 wrapped on its outer surface, and the cable body 2 passes through the inside of the limiting tube 7 and is output. At the same time, the drone 501 drives the cable body 2 through the clamping assembly 6, and moves synchronously at a speed that matches the unwinding speed, and stably transports the cable body 2 to the top of the tower. Specifically: the drone 501 is controlled to take off and move toward the position of the top of the high-voltage line tower, thereby driving the free end of the cable body 2 between the clamping plates 603 to move toward the top of the tower, and the flight position is monitored by the camera. When it reaches the top of the tower, the drone 501 is controlled to land on the top of the tower.

[0049] Finally, to install the cable, the staff at the top of the tower signal the ground staff to release the clamping assembly 6 from the cable body 2. Specifically, the electromagnet 605 is controlled to be energized in reverse to generate a magnetic attraction on the slider 602, so that the slider 602 moves along the slide groove 606 toward the direction close to the electromagnet 605 until it moves to the top of the slide groove 606, thereby releasing the clamping of the cable body 2. The staff at the top of the tower fixes the cable body 2 to the installation position at the top of the tower.

[0050] In the above-mentioned embodiment 1, when the drone 501 encounters resistance from the reverse wind while transporting the cable body 2, its flight speed will also slow down. At this time, when the unwinding motor 103 still unwinds at a speed matching the drone 501, the cable body 2 will change from a taut state to a loose state, thereby causing the cable body 2 to be blown by the wind, resulting in unstable phenomena such as swinging.

[0051] When encountering resistance from the forward wind, the flight speed will also increase. At this time, if the unwinding motor 103 still unwinds at a speed that matches the drone 501, the cable body 2 will be over-tightened. Both of the above situations will hinder the normal transportation of the drone 501, thereby affecting the installation efficiency of the cable body 2. In order to solve the above technical problems, the following embodiment 2 is proposed. Example

[0052] When the detection plates 404 clamp the cable body 2, the number of detection plates 404 on the upper and lower detection assemblies 4 that are in contact with the cable body 2 is the same, and the contacted detection plates 404 compress the detection springs 403. By real-time detection of the number of compressed detection springs 403 on the upper and lower detection assemblies 4, the current slack or tension of the cable body 2 is determined, thereby adjusting the unwinding speed of the unwinding assembly 1 or the transport speed of the transport assembly.

[0053] When the drone 501 is transporting the cable body 2 from the ground to the top of the tower, it is flying diagonally upward. When the number of compression detection springs 403 on the upper detection assembly 4 increases, it means that the cable body 2 is overtightened. The drone 501 is flying at a relatively high speed in the tailwind state. While it is accelerating upward, the unwinding assembly 1 does not accelerate accordingly. As a result, the drone 501 drives the free end of the cable body 2 upward, thereby increasing the number of contacts between the cable body 2 and the upper detection plate 404, which in turn increases the number of compression detection springs 403. At this time, the unwinding motor 103 is controlled to rotate faster, driving the rotating shaft 102 to rotate faster, thereby accelerating the unwinding of the cable body 2 wrapped around its outer surface until the number of compression detection springs 403 on the upper and lower detection assemblies 4 is restored to the same level, and the unwinding motor 103 is stopped from accelerating.

[0054] When the number of compression detection springs 403 on the lower detection assembly 4 increases, it indicates that the cable body 2 is slack. Drone 501 is flying slowly against the wind, and its deceleration does not coincide with the deceleration of unwinding assembly 1, causing the cable body 2 to unwind excessively. This causes the cable body 2 to sag downward, pressing against the lower detection plate 404, thereby increasing the number of compression detection springs 403. At this point, drone 501 is controlled to increase its flight speed, driving cable body 2 to accelerate, thereby straightening and tightening the sagging cable body 2 until the number of compression detection springs 403 on the upper and lower detection assemblies 4 is equalized, and drone 501 stops accelerating.

[0055] By setting up a detection component 4, the cable body 2 is clamped and stabilized when it is unwound; at the same time, the tension state of the cable body 2 is identified and judged, and the transportation component is controlled in time to adjust the transportation speed to prevent the line from being unwound relatively quickly, causing the cable body 2 to be too loose and swinging when encountering wind, resulting in unstable transportation, or the unwinding component 1 is controlled to adjust the unwinding speed to prevent the line from being unwound relatively slowly, which hinders the transportation of the transportation component and ensures the installation efficiency of the cable body 2.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
