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 substations, power plants and other places in the power system. They can ensure the safe and accurate installation of high-voltage cables and improve the stability and reliability of the power system. At the same time, these devices also have the advantages of compact structure, high integration and good portability. They are easy to carry and transport and can meet the installation requirements in different scenarios.

[0003] The Chinese invention patent with application number 201410371896.4 proposes a high-voltage transmission and distribution cable cross-road erection machine and a wiring method, including a wire tension device, a wire tension mechanism, a quick wire pulling mechanism, a lead wire ray device, a cable traction rope and at least two wiring brackets. The lead wire and the cable traction rope are connected to the cable through a mouse-shaped connector in turn. The wiring bracket includes a base, a vertical pole and a wiring crossbar. The time required to use this machine is 1 / 4 of the original time, and only 2 operators are required, while the existing machine wiring requires at least 5 people; more importantly, the lead wire, traction rope, and cable are always suspended in the air, which does not affect road transportation at all.

[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 tip over, 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, but is in a loose state. If wind passes by at this time, the cable will also swing and become unstable; in addition, the cable is generally stored in a coil. 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. It takes a long time to adjust the tension, affecting the installation efficiency.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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 keeps changing 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 cable is not tightened when it is installed and transported to the top of the tower, but 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.

[0028] Embodiment 1:

[0029] 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 component 1, a cable body 2 is wound on the reeling component 1, a limiting tube 7 is arranged on the reeling component 1, a roller 3 is arranged on the top of the reeling component 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, and the end of the limiting tube 7 close to the roller 3 is arranged between the two rollers 3; a detection component 4 is arranged on the roller 3, the free end of the cable body 2 passes through the limiting tube 7, and is clamped in the clamping component 6 after passing through the detection component 4, and the clamping component 6 is arranged on the transport component 5.

[0030] The limiting tube 7 is provided to fix the outgoing direction of the cable body 2 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; the detection component 4 is provided to clamp the cable body 2 for stability when it comes out, and the cable body 2 is kept in a taut state by keeping the unwinding speed and the transportation speed synchronized, and the cable body 2 can be pre-straightened to avoid the cable body 2 being blown by the wind when it is relaxed, causing instability, thereby improving the installation efficiency.

[0031] 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, resulting in unstable outlet of the cable body 2, affecting the installation efficiency of the cable.

[0032] In order to solve the above technical problems, Figure 1-Figure 3 As shown, by setting the 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, ensure the stable clamping of the detection component 4, and ensure the stability of the outlet of the cable body 2. The detection component 4 includes a fixed shaft 401, the fixed shaft 401 is provided with a groove 402 along the circumference, a detection spring 403 is provided in the groove 402, and a detection plate 404 is fixedly provided at the end of the detection spring 403; the detection component 4 is fixedly set at the middle position of the roller 3, 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, the surface of the cable body 2 contacts the detection plate 404, and the distance between the detection components 4 is smaller than the diameter of the cable body 2, so that the detection plate 404 can clamp the cable body 2.

[0033] When in use, the cable body 2 passes through the inside of the limit 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 direction of 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 limit tube 7 to fix the cable body 2, prevent the cable body 2 from swinging, and ensure the stability of the cable body 2.

[0034] 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.

[0035] When the transport assembly 5 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 to fix the end of the cable body 2 on the transport assembly 5 to ensure that the cable body 2 can be transported to the top of the high-voltage line tower for installation.

[0036] In order to solve the above technical problems, Figure 4-Figure 5As shown, by setting a clamping assembly 6 on the transport assembly 5, the cable body 2 is fixed on the transport assembly 5, and the transport assembly 5 then transports the cable body 2 to the top of the high-voltage line tower. The transport assembly 5 includes a drone 501, a support frame 502 is arranged parallel to the bottom of the drone 501, and legs 503 are evenly arranged on the support frame 502. The clamping assembly 6 is fixedly arranged on the legs 503 located in the middle position, and a camera 504 is fixedly arranged at the center of the bottom surface of the drone 501. The clamping assembly 6 includes a symmetrically arranged fixed block 601, and the opposite side of the fixed block 601 is arranged as an inclined surface, 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 located at the top of the slide slot 606, the distance between them is the farthest. When the slider 602 is located at the bottom of the slide slot 606, the distance between them is the shortest. The slider 602 is slidably arranged on the opposite side of the fixed block 601. The slide slot 606 is provided on the opposite side of the fixed block 601. The slider 602 is provided with a protrusion on the side close to the fixed block 601, and the protrusion is clamped in the slide slot 606. A return spring 604 is fixedly arranged on the top of the slider 602. An electromagnet 605 is fixedly arranged on the end of the return spring 604 away from the slider 602. The slider 602 can be made of permanent magnet material. The electromagnet 605 can generate magnetic repulsion or magnetic attraction when it is energized. When the electromagnet 605 is not energized, the slider 602 is located at the top of the slide slot 606, the distance is the farthest, and it is convenient for the staff to place the free end of the cable body 2 therein. The electromagnet 605 is fixedly arranged on the fixed block 601, and a clamping plate 603 is fixedly arranged on the opposite side of the slider 602.

[0037] When in 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 to generate a magnetic repulsive force on the slider 602, so that the slider 602 moves along the slide groove 606 away from the electromagnet 605 until it moves to the bottom of the slide groove 606, thereby clamping and fixing the cable body 2.

[0038] 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 504. When reaching the top of the tower, the drone 501 is controlled to land on the top of the tower.

[0039] At this time, the staff at the top of the tower signaled the ground staff to release the clamping assembly 6 from the cable body 2, specifically: control the electromagnet 605 to reverse power, generate magnetic attraction on the slider 602, so that the slider 602 moves along the slide 606 in the direction close to the electromagnet 605, until it moves to the top of the slide 606, and releases the clamping of the cable body 2. The staff at the top of the tower fixes the cable body 2 at the installation position at the top of the tower. The free end of the cable body 2 is fixed by setting the clamping assembly 6, and the auxiliary transportation assembly 5 transports the cable body 2 to the top of the high-voltage line tower.

[0040] 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.

[0041] To solve the above technical problems, Figure 1 and Figure 6 As shown, the unwinding assembly 1 includes vertical plates 101 arranged in parallel, 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.

[0042] 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 a flight transportation test, it is determined that the unwinding speed is compatible with the flight speed of the drone 501.

[0043] During unwinding, the unwinding motor 103 is controlled to rotate, driving the rotating shaft 102 to rotate, thereby unwinding the cable body 2 wound 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.

[0044] 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.

[0045] 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 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 progress; 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.

[0046] 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 tower to which 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.

[0047] 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 of the slide groove 606, thereby clamping and fixing the cable body 2.

[0048] Then, correct the cable exit point, and the cable body 2 passes through the inside of the limit tube 7 and then passes between the two detection components 4. The cable body 2 resists the detection plate 404, so that the detection plate 404 moves toward the direction of 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.

[0049] 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 wound 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, so as to stably transport the cable body 2 to the top of the tower. Specifically: 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, and the flight position is monitored by the camera 504. When reaching the top of the tower, the drone 501 is controlled to land on the top of the tower.

[0050] 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 the reverse direction to generate a magnetic attraction on the slider 602, so that the slider 602 moves along the slide groove 606 in 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.

[0051] In the above-mentioned embodiment 1, when the drone 501 encounters resistance from adverse 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.

[0052] When encountering resistance from the wind, the flight speed will also increase. At this time, when the unwinding motor 103 still unwinds at a speed matching the UAV 501, the cable body 2 will be over-tightened; both of the above situations will hinder the normal transportation of the UAV 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.

[0053] Embodiment 2:

[0054] When the detection plate 404 clamps the cable body 2, the number of detection plates 404 on the upper and lower detection components 4 that are in contact with the cable body 2 is the same, and the detection plates 404 that are in contact compress the detection springs 403. By detecting the number of compressed detection springs 403 on the upper and lower detection components 4 in real time, the current loose or tight state of the cable body 2 is determined, thereby adjusting the unwinding speed of the unwinding component 1 or the transport speed of the transport component 5.

[0055] The drone 501 drives the cable body 2 from the ground to the top of the tower, and flies obliquely upward. When the number of compression detection springs 403 on the upper detection assembly 4 increases, it means that the cable body 2 is over-tightened. The drone 501 flies fast in the downwind state. When it accelerates upward, the unwinding assembly 1 does not speed up, causing the drone 501 to drive the free end of the cable body 2 to move upward, thereby increasing the number of contacts between the cable body 2 and the detection plate 404 located above, thereby increasing the number of compression detection springs 403 located above. At this time, the unwinding motor 103 is controlled to speed up and drive the rotating shaft 102 to accelerate, thereby accelerating the unwinding of the cable body 2 wound on its outer surface, until the number of compression detection springs 403 on the upper and lower detection assemblies 4 is restored to be consistent, and the unwinding motor 103 is stopped from speeding up.

[0056] When the number of compression detection springs 403 on the detection assembly 4 located below increases, it means that the cable body 2 is loose at this time. The drone 501 is flying slowly in the headwind state. When it decelerates, the unwinding assembly 1 does not decelerate accordingly, resulting in more unwinding of the cable body 2, which causes the cable body 2 to sag downward and press on the detection plate 404 located below, thereby increasing the number of compression detection springs 403 located below. At this time, the drone 501 is controlled to speed up, driving the cable body 2 to accelerate, so as to straighten and tighten the sagging cable body 2 until the number of compression detection springs 403 on the upper and lower detection assemblies 4 is restored to the same, and the drone 501 stops speeding up.

[0057] By setting up the 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 5 is controlled in time to adjust the transportation speed to prevent the line from being relatively fast, 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 relatively slow and hindering the transportation of the transportation component 5, thereby ensuring the installation efficiency of the cable body 2.

[0058] 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, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to 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 protection scope of the present invention.
