Description

Technical Field

[0001] The utility model relates to the technical field of cable maintenance, in particular to a device capable of de-icing live lines. Background Technique

[0002] Icing will not only increase the weight of the line, making the line subject to greater tensile force, but may also cause a sharp decline in electrical performance, leading to problems such as overloading of the line, ice flashover, and galloping. Therefore, the de-icing technology of the line has become one of the keys to ensuring the safe and stable operation of the power system.

[0003] In the prior art, the de-icing technology during the power outage operation of the line at the present stage has been developed maturely, and the DC de-icing technology, robot de-icing technology, etc. have relatively mature applications in the power grid; however, the existing mature de-icing means still have defects. But if the line icing can be removed in the early and middle stages when the icing is relatively light, the risk of line breakage and power outage can be greatly reduced. Therefore, if it is possible to de-ice the live line by using equipment during the line operation, the impact caused by icing is difficult to exceed the bearing range of the line. Therefore, we propose a device capable of de-icing live lines to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a device capable of de-icing live lines.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A device capable of de-icing live lines includes a drone body. A mounting component, a de-icing component and a suspension component are arranged at the bottom of the drone body. The mounting component includes a collar. A telescopic rod is fixedly connected to the bottom of the collar. A connecting rod is arranged at the bottom of the telescopic rod. A movable pulley group is arranged at the bottom of the connecting rod. A traction rope is slidably connected to the outer wall of the movable pulley group. A fixed pulley group is slidably connected to the outer wall of the traction rope. A plurality of springs are arranged between the fixed pulley group and the movable pulley group;

[0007] The de-icing component includes an ice-breaking head. A piston cylinder is fixedly connected to the bottom of the ice-breaking head. A power component is fixedly installed at the bottom of the piston cylinder. A signal transmission device is fixedly installed on the outer surface of the power component. A wire slot is arranged at the top of the ice-breaking head. A line is placed between the wire slot and the ice-breaking head.

[0008] Preferably, fitting plates are fixedly sleeved on the top of the piston cylinder and the bottom of the connecting rod respectively. The outer walls of the fixed pulley set and the movable pulley set are fixedly connected to the outer walls of the two fitting plates respectively. A sliding hole is formed in the outer wall of one of the fitting plates, and the inner wall of the sliding hole is slidably connected to the outer wall of the piston cylinder. Two sliding holes are formed in the outer walls of the two fitting plates, and sliding rods are slidably connected to the inner walls of the two sliding holes. The spring is sleeved on the outer wall of the sliding rod. A nut is threadedly sleeved on the outer wall of the top of the sliding rod. The outer wall of the wire clamping groove is fixedly connected to the outer wall of the top of the connecting rod. The bottom of the telescopic rod is fixedly connected to the top of the wire clamping groove. A hook is slidably connected to the outer wall of the collar. When the collar is subjected to a pulling force, the telescopic rod will be stretched under force. At the same time, the telescopic rod pulls the towing rope. The towing rope bypasses the movable pulley set and the fixed pulley set, and can pull the movable pulley set to move up and down relative to the fixed pulley set when subjected to force.

[0009] Preferably, the two ends of the spring are respectively in contact with the outer walls of the two fitting plates. When the movable pulley set moves up and down relative to the fixed pulley set, it will drive the connecting rod to move up and down, so that it disengages from or presses against the ice-breaking head and compresses or stretches the spring.

[0010] Preferably, two guide sleeves are fixedly connected to the bottom of one of the fitting plates, and the inner walls of the two guide sleeves are respectively slidably connected to the outer walls of the two sliding rods. By providing the guide sleeves, the fitting plate at the bottom is assisted to move up and down.

[0011] Preferably, the ice-breaking head is closely connected to the top of the connecting rod in the spring relaxation state.

[0012] Preferably, the suspension assembly includes a motor. A groove and a rectangular delivery slot are formed in the outer wall of the UAV body. The inner wall of the groove is fixedly connected to the outer wall of the motor. One end of the output shaft of the motor is fixedly connected to a conical block. A rectangular block is fixedly connected to the outer wall of the conical block. A suspension ring is sleeved on the outer wall of the conical block. A pulling rope is fixedly connected to the bottom of the suspension ring. The bottom of the pulling rope is fixedly connected to the top of the hook. By providing the conical block and the rectangular block, it is convenient to limit the suspension ring on the UAV body and facilitate subsequent disassembly.

[0013] Preferably, a through hole is formed in the inner wall of the groove, and the inner wall of the through hole is rotatably connected to the outer wall of the output shaft of the motor.

[0014] Preferably, the conical block and the rectangular block are located in the rectangular delivery slot.

[0015] Preferably, two legs are installed at the bottom of the UAV body. By providing the legs, the UAV body is supported.

[0016] Preferably, the suspension ring is located on one side of the rectangular block.

[0017] Compared with the prior art, the advantages of the present utility model are as follows:

[0018] In this solution, by setting up a collar, a telescopic rod, a fixed pulley set, a spring, a towing rope, a movable pulley set, a hook and a connecting rod, the connecting rod and the wire clamping groove are driven to expand and contract by their own weight, facilitating the subsequent insertion of the wire between the wire clamping groove and the ice-breaking head.

[0019] By setting up an ice-breaking head, a piston cylinder, a power component, a signal transmission device, a wire clamping groove, a sliding rod, a guide sleeve and an assembly plate, the piston cylinder transmits vibration to the wire between the ice-breaking head and the connecting rod, causing high-frequency vibration of the wire to remove the ice coating on the wire, realizing remote control for de-icing, with fewer operating personnel required, shorter time spent, good de-icing effect, and no need for power outage operation.

[0020] By setting up a groove, a rectangular dropping groove, a motor, a conical block, a rectangular block, a hanging ring and a pulling rope, it is convenient to hang the mounting component and the ice-breaking component on the unmanned aerial vehicle body, and the device is driven by the unmanned aerial vehicle body to lift into the air, facilitating de-icing of the wire.

[0028] The de-icing component 2 includes an ice-breaking head 21. After the power component 23 is triggered, high-speed gas is generated inside, and the vibration is transmitted to the line 3 between the ice-breaking head 21 and the connecting rod 19 through the piston cylinder 22, causing high-frequency vibration of the line 3 to remove the ice covering the line 3. The bottom of the ice-breaking head 21 is fixedly connected to a piston cylinder 22. A power component 23 is fixedly installed at the bottom of the piston cylinder 22. High-speed gas can be generated inside the power component 23.

A sliding hole is opened on the outer wall of one of the assembly plates 28, and the inner wall of the sliding hole is slidably connected to the outer wall of the piston cylinder 22. The assembly plate 28 connected to the connecting rod 19 slides on the piston cylinder 22 by gravity.

[0030] The top of the piston cylinder 22 penetrates through the bottom of the other assembly plate 28, and the piston cylinder 22 is supported by the ice-breaking head 21.

The conical block 44 causes the rectangular block 45 to rotate, and the limit on the suspension ring 46 can be released. A rectangular block 45 is fixedly connected to the outer wall of the conical block 44. The conical block 44 and the rectangular block 45 are located in the rectangular delivery slot 42.

[0033] When the present utility model is in use, the maximum pressure received by the spring 14 is:

[0034] Among them, P max is the maximum pressure received by the spring 14, n d is the number of movable pulleys in the movable pulley group 16, M1 is the weight of the hanging component 1, M2 is the weight of the de-icing component 2, and g is the acceleration due to gravity.

[0035] Thus, it can be inferred that the maximum distance between the ice-breaking head 21 and the wire card slot 25 is:

[0036]

[0037] Among them, L max is the maximum distance between the ice-breaking head 21 and the wire card slot 25, P max is the maximum pressure received by the spring 14, and k is the elastic coefficient of the spring 14.

[0038] This maximum distance should be greater than the diameter of the de-icing line 3 required, so:

[0039]

[0040] Among them, L max is the maximum distance between the ice-breaking head 21 and the wire card slot 25, nd where \(n\) is the number of movable pulleys in the movable pulley block 16, \(M_1\) is the weight of the mounting component 1, \(M_2\) is the weight of the de-icing component 2, \(g\) is the acceleration due to gravity, \(k\) is the spring constant of the spring 14, and \(L\) D is the diameter of the de-icing line 3 required.

[0041] Meanwhile, to ensure that the pressure is large enough after the mounting component 1 clamps the line 3 (the greater the pressure, the less energy is lost when vibration is transmitted to the line 3), which is at least twice the self-weight of the device. When the device is not subject to external forces:

[0042] \(P\) min \(=k\times L\) min \(>2\times(M_1 + M_2)\times g\)

[0043] where \(P\) min is the static pressure on the spring 14 when the device is not subject to external forces, \(k\) is the spring constant of the spring 14, and \(L\) min is the compression of the spring 14 when the device is not subject to external forces (the length of the device's slide bar 26 remains unchanged, and this value is only related to the length of the spring 14), \(M_1\) is the weight of the mounting component 1, \(M_2\) is the weight of the de-icing component 2, and \(g\) is the acceleration due to gravity.

[0044] In summary, the value range of the spring constant of the spring 14 is:

[0045]

[0046] where \(M_1\) is the weight of the mounting component 1, \(M_2\) is the weight of the de-icing component 2, \(g\) is the acceleration due to gravity, and \(L\) min is the compression of the spring 14 when the device is not subject to external forces (the length of the device's spring rod remains unchanged, and this value is only related to the length of the spring 14), \(n\) d is the number of movable pulleys in the movable pulley block 16, and \(L\) D is the diameter of the de-icing line 3 required.

[0047] Therefore, for lines 3 of different thicknesses, the adaptability of the present invention can be adjusted by changing the spring constant of the spring 14, and it can be applied to power transmission and distribution lines or ground wires.

[0048] Working principle: During use, the motor 43 operates to rotate the conical block 44 and the rectangular block 45, causing the rectangular block 45 to face downwards. The sling 46 is hung on the conical block 44. Then the motor 43 operates to make the conical block 44 and the rectangular block 45 face upwards, limiting the sling 46 on the conical block 44. The hook 18 is hooked onto the suspension assembly 17, and then the mounting assembly 1 and the deicing assembly 2 are erected. After the UAV body 4 takes off, the hook 18 is hooked onto the collar 11. The suspension assembly 17 gradually rises, and the telescopic rod 12 gradually extends. The movable pulley block 16 moves upwards as the telescopic rod 12 extends and compresses the spring 14. When the UAV body 4 leaves the ground, the spring 14 is under the greatest pressure at this time, and the ice-breaking head 21 is separated from the wire slot 25. The device is brought close to the line 3 so that the line 3 is clamped between the ice-breaking head 21 and the wire slot 25. At this time, the suspension assembly 17 gradually descends, and the spring 14 gradually expands and contracts, pushing the movable pulley block 16 downwards to clamp the line 3 tightly between the wire slot 25 and the ice-breaking head 21. Then, through the remote control device or the signal transmitting device installed on the UAV body 4, a start signal is transmitted to the signal transmission device 24, triggering the power assembly 23 to generate high-speed gas inside. The vibration is transmitted to the line 3 between the ice-breaking head 21 and the connecting rod 19 through the piston cylinder 22, causing the line 3 to vibrate at a high frequency to remove the ice covering the line 3.

[0049] As described above, it is only the preferred specific implementation manner of this embodiment, but the protection scope of this embodiment is not limited thereto. Any person skilled in the art within the technical scope disclosed in this embodiment, according to the technical solution of this embodiment and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of this embodiment.
