Description

Technical Field

[0001] The invention relates to the technical field of electric power maintenance, and in particular to an electric power detection device used for high-altitude operations. Background Art

[0002] Transmission lines are the line guarantee of the power supply system. The stable and continuous operation of transmission lines ensures the stability of the power system. To ensure the smooth operation of high-voltage transmission lines, it is necessary to judge and analyze the faults of high-voltage transmission lines throughout the process, which requires fault diagnosis of the operating conditions of transmission lines.

[0003] When inspecting and repairing cables of some existing power transmission lines, a line leakage measuring instrument is used for detection. When in use, a clamp ammeter used as a detection clamp component is connected to the cable line to measure the leakage of the line. However, in the actual use of urban lines, when the insulating rod connecting the instrument is moved, it is often easily blocked by obstacles such as bushes, resulting in the need to interrupt the detection and move it to an unobstructed area for re-detection, which reduces the efficiency of the detection and is inconvenient to use. Summary of the invention

[0004] The purpose of the present invention is to provide an electric power detection device for high-altitude operations.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A power detection device for high-altitude operation, comprising a base mechanism, a detection mechanism fixed on the top of the base mechanism, and a handheld terminal connected to the detection mechanism through a wireless signal, wherein the base mechanism comprises a shell, a through hole is provided in the middle of the shell, and a blower for movement is fixed inside the through hole, a threaded sleeve is fixed at the bottom of the shell, and a pull rod mechanism is screwed to the shell through the threaded sleeve, a second cavity is provided inside the top of the shell, and a landing mechanism for landing is provided inside the second cavity, and a lifting mechanism is provided on the shell;

[0007] The detection mechanism includes two detection chuck assemblies for detecting cables, the two semicircular detection chuck assemblies form a circular structure, a connecting shaft is fixed at the bottom end of the detection chuck assembly, and the end of the connecting shaft is connected to the adjustment unit, and the adjustment unit for driving the two detection chuck assemblies is fixed to the top surface of the shell;

[0008] The pull rod mechanism includes a plurality of insulating rod bodies which are screwed together end to end in sequence, wherein an insulating rod body at the end is screwed together with the threaded sleeve, a strip through hole is provided on the outer wall of an insulating rod body at the end, and a second bobbin is rotatably connected inside, a clockwork spring is fixed between the bottom end of the second bobbin and the inner wall of the insulating rod body, and a tow rope with one end passing through the strip through hole and fixed to the threaded sleeve is wound around the second bobbin. When in use, the whole is placed under the municipal cable line, and then the adjustment unit makes the two detection clamp assemblies open so that the cable line is placed between the two detection clamp assemblies, and then the two detection clamp assemblies are closed. After closing, the plurality of insulating rod bodies are spliced ​​into a long Rod-shaped structure, then pull one end of the tow rope and fix it on the threaded sleeve, and connect and fix the end of the insulating rod body to the threaded sleeve. At this time, the maintenance personnel can pull the insulating rod body to push the detection equipment to move as a whole, and use the blower to blow air, so as to more conveniently push the whole to move on the cable line. When moving, two detection clamp assemblies are used to detect the cable line data and transmit it to the handheld terminal. When encountering obstacles such as bushes, the insulating rod body can be rotated to make the insulating rod body separate from the threaded sleeve. The maintenance personnel throw the insulating rod body over obstacles such as bushes, and then climb over them themselves, and continue to pull the insulating rod body. At this time, the insulating rod body continues to pull the whole body to move through the action of the tow rope, which is convenient to use.

[0009] Furthermore, the adjustment unit includes a mounting frame, and the mounting frame is internally symmetrically connected to two rotating shafts, and gears are sleeved on the two rotating shafts, and the two gears are meshed with each other, wherein an end of one rotating shaft is fixed to a motor shaft of a first motor fixed inside the mounting frame, and the ends of the two connecting shafts pass through the side walls of the mounting frame and are respectively fixed to a corresponding rotating shaft, and by starting the first motor, the gears can be driven to rotate to adjust the opening and closing of the two detection chuck assemblies.

[0010] Furthermore, a first cavity is provided on the top of the shell, and a hollow tube with one end extending into the inside of the first cavity is rotatably connected to the top surface of the shell. A second motor is installed inside the first cavity. Bevel gears are fixed on the bottom end of the inverted J-shaped hollow tube and the motor shaft of the second motor, and the two bevel gears are meshed with each other. During the inspection process of the two inspection chuck assemblies, the hollow tube can be driven to rotate by the second electric drive so that the hollow tube can cross the cable. In this way, when a malfunction occurs and causes the two inspection chuck assemblies to open and separate from the cable, the hollow tube can be connected to the cable to avoid overall falling and damage.

[0011] Furthermore, a third motor is fixed inside the first cavity, and a first spool is fixed on the motor shaft of the third motor, a limiting rope with one end passing through the hollow tube is wound on the first spool, an iron sheet is fixed on the end of the limiting rope, and an electromagnet for adsorbing the iron sheet is embedded and fixed at the corner of the top surface of the shell. When the second motor is started, the hollow tube can be rotated under the action of the bevel gear, so that the other end of the hollow tube crosses the cable line, and then the third motor is started to release the limiting rope. At this time, the iron sheet moves down, and then the electromagnet is used to adsorb the iron sheet for fixing, and then the hollow tube is rotated in the opposite direction to make the limiting rope cross the cable line, and then the two detection chuck assemblies are opened, and the whole falls until the limiting rope contacts the cable line, and then the third motor continues to release the limiting rope, which makes it easy to drop the whole from the cable line, and it is convenient to use.

[0012] Furthermore, the landing mechanism includes an umbrella body, which is arranged on one side of a push plate, and the push plate is connected to the side wall of the second cavity through a compression spring. The compression spring pushes the push plate to move, and the push plate can push the umbrella body out of the second cavity, so that the umbrella body can be opened to achieve a slow descent effect during the falling process.

[0013] Furthermore, an electric door is installed on the shell at a position corresponding to the second cavity, and the electric door can be used to limit the position of the umbrella body, and when the umbrella body falls as a whole, the electric door can be opened to move the umbrella body out.

[0014] Furthermore, the umbrella body is arranged above the blower fan, and the blower fan can be used to open the umbrella body separated from the second cavity, thereby reducing the probability of the entire umbrella body directly falling.

[0015] Furthermore, hooks are fixed on both sides of the threaded sleeve at the bottom of the shell, and the hooks can be connected to the traction rope. In this way, when the whole needs to be installed on the cable line, the traction rope can be pulled by an external lifting device to pull the whole to the cable line position, which is convenient to use.

[0016] Beneficial effects of the present invention:

[0017] 1. By arranging a pull rod mechanism at the bottom of the shell and a blower fan in the middle of the shell, when the whole is moved, multiple insulating rods can be spliced ​​into a long rod structure, and the end of the insulating rod can be connected and fixed with the threaded sleeve, so that the maintenance personnel can push the detection equipment to move as a whole through the insulating rod, and use the blower fan to blow air, so that the whole can be pushed to move on the cable line more conveniently. At the same time, the insulating rod can be rotated to separate the insulating rod from the threaded sleeve. The maintenance personnel throw the insulating rod over obstacles such as bushes, and then climb over them, and continue to pull the insulating rod. At this time, the insulating rod continues to pull the whole to move through the tow rope, which is convenient to use; by arranging an umbrella body inside the shell, the umbrella body is opened, and the blower fan accelerates the opening of the umbrella body, so as to achieve the effect of slow descent and reduce the probability of direct falling and damage of the whole.

[0018] 2. A rotatable hollow tube is arranged on the shell, and the second electric drive is used to rotate the hollow tube to cross the cable line. In this way, when a fault occurs and causes the two detection clamp assemblies to open and separate from the cable line, the hollow tube can be connected to the cable line to prevent the whole from falling and being damaged. At the same time, the second motor is started, and under the action of the bevel gear, the hollow tube can be rotated so that the other end of the hollow tube crosses the cable line. Then the third motor is started to release the limit rope. At this time, the iron sheet moves down, and then the electromagnet is used to adsorb the iron sheet for fixation. Then the hollow tube is rotated in the opposite direction to make the limit rope cross the cable line. Then the two detection clamp assemblies open, and the whole falls until the limit rope contacts the cable line. Then the third motor continues to release the limit rope, which makes it easy to drop the whole from the cable line. It is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

When the first motor 232 is started, the gear 234 can be driven to rotate to adjust the opening and closing of the two detection chuck assemblies 210.

[0032] The pull rod mechanism 600 includes a plurality of insulating rod bodies 610 which are screwed together end to end in sequence, wherein an insulating rod body 610 located at the end is screwed together with a threaded sleeve 130, a strip through hole 620 is provided on the outer wall of an insulating rod body 610 located at the end, and a second bobbin 630 is rotatably connected inside, a clockwork spring 640 is fixed between the bottom end of the second bobbin 630 and the inner wall of the insulating rod body 610, and a tow rope with one end passing through the strip through hole 620 and fixed to the threaded sleeve 130 is wound around the second bobbin 630. When in use, the whole is placed under the municipal cable line, and then the adjustment unit makes the two detection clamp assemblies 210 open, so that the cable line is placed between the two detection clamp assemblies 210, and then the two detection clamp assemblies 210 are closed. After closing, the plurality of insulating rod bodies 610 are assembled. It is connected into a long rod-shaped structure, and then one end of the tow rope is pulled and fixed on the threaded sleeve 130, and the end of the insulating rod body 610 is connected and fixed to the threaded sleeve 130. At this time, the maintenance personnel can pull the insulating rod body 610 to push the detection equipment to move as a whole, and use the blower 500 to blow air, so as to more conveniently push the whole to move on the cable line. When moving, the two detection clamp assemblies 210 are used to detect the cable line data and transmit it to the handheld terminal 700. When encountering obstacles such as bushes, the insulating rod body 610 can be rotated to make the insulating rod body 610 separate from the threaded sleeve 130. The maintenance personnel throws the insulating rod body 610 over obstacles such as bushes, and then after climbing over them, they continue to pull the insulating rod body 610. At this time, the insulating rod body 610 continues to be pulled as a whole by the action of the tow rope, which is convenient to use.

[0033] Specifically, a first cavity 111 is opened on the top of the shell 110, and the top surface of the shell 110 is rotatably connected to a hollow tube 310 with one end extending into the first cavity 111, and a second motor 320 is installed inside the first cavity 111, and a bevel gear 321 is fixed to the bottom end of the inverted J-shaped hollow tube 310 and the motor shaft of the second motor 320, and the two bevel gears 321 are meshed with each other. During the detection process of the two detection chuck assemblies 210, the hollow tube 310 can be driven to rotate by the second electric drive, so that the hollow tube 310 can cross the cable line. In this way, when a malfunction occurs and causes the two detection chuck assemblies 210 to open and separate from the cable line, the hollow tube 310 can be connected to the cable line to avoid overall falling and damage. A third motor 330 is also fixed inside the first cavity 111, and a first spool 331 is fixed to the motor shaft of the third motor 330. The shaft 331 has one end wound around a limiting rope 340 that passes through the hollow tube 310. An iron sheet 140 is fixed to the end of the limiting rope 340. An electromagnet 350 for adsorbing the iron sheet 140 is embedded and fixed at the corner of the top surface of the shell 110. The second motor 320 is started, and under the action of the bevel gear 321, the hollow tube 310 can be rotated so that the other end of the hollow tube 310 crosses the cable. Then the third motor 330 is started to release the limiting rope 340. At this time, the iron sheet 140 moves downward, and then the electromagnet 350 is used to adsorb the iron sheet 140 for fixing it. Then the hollow tube 310 is rotated in the opposite direction so that the limiting rope 340 crosses the cable. Then the two detection clamp assemblies 210 are opened, and the whole falls until the limiting rope 340 contacts the cable. Then the third motor 330 continues to release the limiting rope 340, which makes it easy to drop the whole from the cable, which is convenient to use.

[0034] Specifically, the landing mechanism 400 includes an umbrella body 410, which is arranged on one side of a push plate 420. The push plate 420 is connected to the side wall of the second cavity 112 by a compression spring 430. The compression spring 430 pushes the push plate 420 to move, and the push plate 420 can push the umbrella body 410 out of the second cavity 112. In this way, the umbrella body 410 can be opened to achieve a slow descent during the falling process. An electric door 440 is installed on the shell 110 at a position corresponding to the second cavity 112. The electric door 440 can be used to limit the position of the umbrella body 410, and when the whole falls, the electric door 440 can be opened to move the umbrella body 410 out of the second cavity 112, thereby reducing the probability of the whole falling directly.

[0035] Working principle: When in use, first place the detection device at the detection position, then adjust the unit to open the two detection chuck assemblies 210 so that the cable is placed between the two detection chuck assemblies 210, and then close the two detection chuck assemblies 210. After closing, splice multiple insulating rod bodies 610 into a long rod-shaped structure, then pull one end of the tow rope to fix it on the threaded sleeve 130, and connect and fix the end of the insulating rod body 610 to the threaded sleeve 130. After fixing the tow rope set inside the insulating rod body 610 to the side wall of the threaded sleeve 130, screw the insulating rod body 610 into the threaded sleeve 130 set on the bottom surface of the shell 110, or connect the insulating rod body 610 to the threaded sleeve 130, and then directly lift the shell 110 upward to connect the detection chuck assembly 210 to the cable, so as to fix the entire detection device;

[0036] The hook 120 can also be connected to the lifting structure to be lifted, and then the opening and closing of the detection chuck assembly 210 can be remotely controlled by the handheld terminal 700. The rotating shaft 233 and the gear 234 are rotated by the drive of the first motor 232. At this time, the detection chuck assembly 210 is initially in an open state. After the detection chuck assembly 210 is placed in a suitable position, the detection chuck assembly 210 is remotely controlled to be closed by the handheld terminal 700, so that the detection chuck assembly 210 can just wrap the line to be detected.

[0037] After placement is completed, the detection is started by remote control through the handheld terminal 700. During the detection process, the blower fan 500 arranged on one side of the housing 110 starts to work, and the detection device starts to move in one direction along the line. At the same time, the detection device can also be driven to move by the drag rope between the lower insulating rod body 610 and the threaded sleeve 130 to achieve continuous detection of the line.

[0038] After the detection is completed, the device is recovered. When the detection height is too high, the detection chuck assembly 210 can be controlled to open, so that the detection device can fall freely. At this time, the landing mechanism 400 arranged on the side wall of the shell 110 starts to work. After the parachute 410 pops out, under the action of the continuously working blower 500, the parachute 410 can be quickly opened to achieve a slow drop of the device.

[0039] When the terrain is complex and the height is moderate, the hollow tube 310 is rotated under the drive of the second motor 320 to move the limit rope 340 to the direction of the diagonal line, and then the third motor 330 is started to release the limit rope 340 wrapped around the outside of the first spool 331, and the iron sheet 140 arranged at one end of the limit rope 340 begins to fall under the action of gravity. After falling to a certain position, the iron sheet 140 generates suction to the electromagnet 350, and at this time the limit rope 340 surrounds the outside of the line, and then by opening the detection chuck assembly 210 and driving the third motor 330, the limit rope 340 is slowly released, and the device also slowly descends.
