Description

[0002] Grounding wires are the basic guarantee for ensuring the safety of personnel and maintenance operations. When workers are inspecting high-voltage cables, they usually use drones to install wiring devices on the surface of the cables. Using drones can prevent personnel from directly contacting high-voltage power lines or dangerous environments, reducing the risk of injury to workers. Drones can complete grounding work in a shorter time and can also adapt to complex terrain and environments, such as mountainous areas, forests, swamps and other difficult-to-reach places. They can easily fly over obstacles or cliffs to perform grounding work;

[0003] When the wiring device is automatically removed, it is necessary to use a drone to lift the pull ring of the wiring device upwards to separate the wiring device from the high-voltage cable. Since the existing wiring device is not convenient for detecting the electromagnetic field around the high-voltage cable, the high-voltage cable will cause the intensity of the surrounding electromagnetic field to change when affected by wind direction or air humidity. When the electromagnetic field intensity increases, it may affect the installation and removal of the wiring device by the drone. The electromagnetic field may damage the internal components of the drone. In addition, when the existing wiring device is disassembled, it is not convenient to automatically detach the ground wire. The drone needs to carry the wiring device and the ground wire together and fall. The weight of the ground wire may increase the burden on the drone, thereby increasing the energy consumption of the drone.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 12 The present invention provides a technical solution: an automatic hanging and removing wiring device for a drone with electric field detection capability, comprising a shell 1, a clamping plate 2 is rotatably connected inside the shell 1, an elastic telescopic rod 3 is installed inside the shell 1, an elastic clamping block 4 is installed inside the clamping plate 2, a connecting rod 5 is rotatably connected to the back end of the clamping plate 2, a pull rod 6 is rotatably connected to the end of the connecting rod 5, a pull ring 7 is arranged at the top of the shell 1, an electric field detector 8 is installed on the inner surface of the shell 1, a controller 9, a solar panel 10 and a power storage module 11 are installed on the outer surface of the shell 1, a roller 12 is arranged inside the shell 1, a ground wire 13 is installed at the bottom of the shell 1, and an extension mechanism 14 is arranged at the top of the shell 1 and the upper end surface of the shell 1, and the extension mechanism 14 is used to change the height of the pull ring 7;

[0043] A shedding mechanism 15, which is disposed inside the housing 1 and at the bottom of the housing 1, and is used to automatically shear off the ground wire 13 when the drone pulls the pull ring 7;

[0044] The power assist component 16 is arranged in the middle of the housing 1 and inside the roller 12, and is used to assist the ground wire 13 when it falls off so that it falls off quickly.

[0045] Preferably, the number of the clamping plates 2 is two groups, and they are symmetrically distributed inside the housing 1, and the back ends of the clamping plates 2 are in conflict with the ends of the elastic telescopic rods 3;

[0046] During operation, when the cable is affected by wind direction or air humidity, the intensity of the surrounding electromagnetic field will change. When the electromagnetic field intensity increases, it may affect the installation and removal of the wiring device by the drone, and the electromagnetic field may damage the internal components of the drone. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: first, the pull ring 7 is hooked by the drone, and then the drone is lifted into the air. At this time, the pull ring 7 is affected by gravity and drives the pull rod 6 to slide upward. When sliding, the pull rod 6 will rotate the splint 2 inside the shell 1 through the connecting rod 5 to open its bottom. At this time, the cable is installed inside the splint 2. At this time, the elastic clamp 4 inside the splint 2 will clamp the cable. At this time, the drone is separated from the wiring device, and the pull rod 6 will automatically reset due to the spring force. Then, the pull rope is pulled. At this time, the displacement sensor 161 detects When the pull rope is displaced, the position sensor 164 is in working state. When the pull rope is pulled, the roller 12 will rotate. After the roller 12 rotates two circles clockwise, the sensing block 165 of the inner ring 162 will contact the position sensor 164 twice. At this time, the torsion force of the torsion spring reaches the limit, and then the electric push rod B166 will drive the friction block 167 to move downward, so that the friction block 167 leaves the inner wall of the roller 12. Then, when the friction block 167 moves downward, it will squeeze the insertion rod 168, so that the insertion rod 168 is inserted into the limiting hole on the surface of the turntable 163, thereby locking the inner ring 162. At this time, the roller 12 can rotate on the surface of the inner ring 162. Then, when the ground wire 13 enters the housing 1, the insertion block 153 will lock the ground wire 13. At this time, the ground wire 13 is in a locked state, and the position sensor 164 is in a dormant state through the displacement sensor 161;

[0047] When the cable needs to be disassembled after maintenance, the electromagnetic field around the cable is detected by the electric field detector 8. The controller 9 controls the extension length of the extended end of the electric push rod A145 according to the strength of the magnetic field around the cable. The electric push rod A145 will push the slide bar 144 to slide inside the connecting platform 141, thereby pushing the extension platform to rise. When the extension platform rises, it will pull the support rod 142 to slide inside the slide groove. When the extension platform rises, it will drive the pull ring 7 to rise, thereby expanding the distance between the pull ring 7 and the shell 1. When the UAV pulls the pull ring 7, the pull ring 7 is affected by gravity and causes the pull rod 6 to slide upward, and the pull rod 6 drives the connecting rod 5 to open the bottom of the clamping plate 2, thereby facilitating the cable to fall off. When the pull rod 6 rises, it will pass through the long block to make the piston rod B155 slide upward inside the oil tank B154, so that the oil inside the oil tank A151 is injected into the oil tank B154. At this time, the piston rod B155 contracts toward the inside of the oil tank B154, and the piston rod B155 drives the plug block 1 when it contracts. 53 contracts inwardly, so that the plug 153 loses the limiting effect on the ground wire 13. At this time, the ground wire 13 will fall downward. When the displacement sensor 161 senses the movement of the ground wire 13, it will put the position sensor 164 into working state, and the friction block 167 will move upward through the electric push rod B166 to make it resist the inner wall of the roller 12. At this time, the plug 168 will automatically reset under the influence of the spring. At this time, the torsion spring will drive the inner ring 162 to rotate synchronously with the roller 12, thereby giving a boost to the ground wire 13 to ensure that the ground wire 13 It will not get stuck during operation. When the inner ring 162 rotates two circles clockwise, the sensing block 165 will contact the position sensor 164 twice, and the electric push rod B166 will drive the friction block 167 to move downward, so that the friction block 167 leaves the inner wall of the roller 12. Then, the friction block 167 will squeeze the insertion rod 168 when moving downward, so that the insertion rod 168 is inserted into the limiting hole on the surface of the turntable 163, and the inner ring 162 is locked, so that the roller 12 can rotate on the surface of the inner ring 162, so that the ground wire 13 can fall off quickly.

[0048] As an embodiment of the present invention, there are two groups of splints 2, which are symmetrically distributed inside the shell 1. The back ends of the splints 2 are in contact with the ends of the elastic telescopic rods 3. When working, the arrangement of the two groups of splints 2 can achieve a more stable cable clamping effect. The ends of the elastic telescopic rods 3 are in contact with the back ends of the splints 2, which can automatically reset the splints 2.

[0049] As an embodiment of the present invention, the extension mechanism 14 includes a connecting platform 141 installed at the top of the shell 1, a support rod 142 slides in the upper end slide groove of the connecting platform 141, and a rotating block is rotatably connected to the end of the support rod 142, an extension plate 143 is installed on the top of the rotating block, a pull ring 7 is installed on the top of the extension plate 143, and a sliding rod 144 is installed at the bottom of the extension plate 143. The sliding rod 144 slides within a limited position in the connecting platform 141, and an electric push rod A145 is installed at the bottom of the connecting platform 141. The protruding end of the electric push rod A145 is connected to the bottom of the extension plate 143. When working, the electric field detector 8 can form a safe distance between the pull ring 7 and the shell 1 according to the strength of the electromagnetic field around the cable. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the electric push rod A145 pushes the extension plate 143 to rise, so that the pull rod 6 slides upward to the limit position on the connecting platform 141, and the support rod 142 slides synchronously inside the slide groove of the connecting platform 141.

[0050] As an embodiment of the present invention, there are two groups of support rods 142, which are diagonally distributed inside the connecting platform 141. The establishment of the two groups of support rods 142 can ensure the stability of the extension plate 143 when it is rising.

[0051] As an embodiment of the present invention, the shedding mechanism 15 includes an oil tank A151 installed at the side end of the shell 1, a piston rod A152 is limitedly slid inside the oil tank A151, an insert block 153 is installed at the end of the piston rod A152, an oil tank B154 is installed inside the shell 1, a piston rod B155 is limitedly slid inside the oil tank B154, a long block is connected between the end of the piston rod B155 and the pull rod 6, a hose is connected between the oil tank A151 and the oil tank B154, and when working, when the drone pulls the pull rod 6, it will drive the ground wire 13 not It is convenient to automatically fall off, which will increase the burden on the drone and reduce its work efficiency and energy consumption. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: when the pull rod 6 rises, it will cause the piston rod B155 to slide upward inside the oil tank B154 through the long block, so that the oil inside the oil tank A151 is injected into the oil tank B154. At this time, the piston rod B155 contracts toward the inside of the oil tank B154. When the piston rod B155 contracts, it will drive the plug block 153 to contract inward, so that the plug block 153 loses the limiting effect on the ground wire 13.

[0052] As an embodiment of the present invention, a spring is installed between the back end of the plug block 153 and the end of the piston rod A152. The lower end of the plug block 153 is inclined. The inclined design of the lower end of the plug block 153 forms a wedge structure, which is relatively simple to install. When it falls off, the plug block 153 needs to be moved as a whole.

[0053] As an embodiment of the present invention, the power assist assembly 16 includes a displacement sensor 161 arranged inside the housing 1, an inner ring 162 rotates inside the roller 12, the side end of the inner ring 162 is rotatably connected to the turntable 163, a limited position hole is provided on the surface of the turntable 163, a position sensor 164 is installed on the side of the turntable 163, a sensing block 165 is installed on the side end of the inner ring 162, a groove is provided inside the inner ring 162, an electric push rod B166 is installed inside the groove, and a friction block 1 is installed on the protruding end of the electric push rod B166 67, the inner ring 162 has a sliding limit rod 168 on the side. When working, in order to prevent the ground wire 13 from getting stuck inside the shell 1 during operation, causing the ground wire 13 to be unable to fall off, thereby causing a safety hazard, this embodiment of the present invention can solve the above problem. The specific implementation method is as follows: the electric push rod B166 pushes the friction block 167 to fit the inner wall of the roller 12. At this time, the torsion spring will drive the inner ring 162 and the roller 12 to rotate synchronously, thereby giving the ground wire 13 a boost to ensure that the ground wire 13 will not get stuck during operation.

[0054] As an embodiment of the present invention, the solar panel 10 converts light energy into electrical energy, and then stores the electrical energy through the power storage module 11. The power storage module 11 provides power for the controller 9. The electric field detector 8 forms data information after receiving the electromagnetic field strength. The controller 9 forms first control information after receiving the data information, and then controls the extension mechanism 14 to start through the first control information. The controller 9 starts the electric push rod A145 through the first control information, and the electric push rod A145 controls the distance between the pull ring 7 and the shell 1.

[0055] When the electric field detector 8 sends data information, the controller 9 sends first control information. The first control information causes the electric push rod to extend to different lengths to ensure a safe distance between the pull ring 7 and the housing 1 .

[0056] As an embodiment of the present invention, the displacement sensor 161 generates transmission information when detecting that the ground wire 13 is moving, and the controller 9 generates second control information when receiving the transmission information. The second control information controls the start and sleep of the power assist component 16. The sensing block 165 forms position information when contacting the position sensor 164 twice.

The electric push rod B166 controls the inner ring 162 to lock, so that the roller 12 rotates on the surface of the inner ring 162.

[0057] The displacement sensor 161 generates first transmission information when detecting the movement of the ground wire 13 and generates second transmission information when detecting the stationary ground wire 13. When receiving the first transmission information and the second transmission information, the controller 9 generates second control information for controlling the sleep and start-up of the position sensor 164.

[0058] Working principle: When using the drone with electric field detection capability to automatically hang and remove the wiring device, first hook the pull ring 7 through the drone, and then the drone rises into the air. At this time, the pull ring 7 is affected by gravity and drives the pull rod 6 to slide upward. When sliding, the pull rod 6 will rotate the clamp plate 2 inside the shell 1 through the connecting rod 5 to open its bottom. At this time, the cable is installed inside the clamp plate 2. At this time, the elastic clamp block 4 inside the clamp plate 2 will clamp the cable. At this time, the drone is separated from the wiring device, and the pull rod 6 will automatically reset due to the spring force. Then, by pulling the pull rope, the displacement sensor 161 detects the displacement of the pull rope, so that the position sensor 164 is in working state, and the roller 12 rotates when the pull rope is pulled. After the roller 12 rotates two circles clockwise, the sensing block 165 of the inner ring 162 will contact the position sensor 164 twice. At this time, the torsion force of the torsion spring reaches the limit, and then the electric push rod B166 will drive the friction block 167 to move downward, so that the friction block 167 leaves the inner wall of the roller 12, and then the friction block 167 will squeeze the insertion rod 168 when moving downward, so that the insertion rod 168 is inserted into the limiting hole on the surface of the turntable 163, thereby locking the inner ring 162. At this time, the roller 12 can rotate on the surface of the inner ring 162, and then when the ground wire 13 enters the housing 1, the insertion block 153 will lock the ground wire 13. At this time, the ground wire 13 is in a locked state, and the position sensor 164 is in a dormant state through the displacement sensor 161;

[0059] When the cable needs to be disassembled after maintenance, the electromagnetic field around the cable is detected by the electric field detector 8. The controller 9 controls the extension length of the extended end of the electric push rod A145 according to the strength of the magnetic field around the cable. The electric push rod A145 will push the slide bar 144 to slide inside the connecting platform 141, thereby pushing the extension platform to rise. When the extension platform rises, it will pull the support rod 142 to slide inside the slide groove. When the extension platform rises, it will drive the pull ring 7 to rise, thereby expanding the distance between the pull ring 7 and the shell 1. To prevent the drone from being affected by the electromagnetic field, when the drone pulls the pull ring 7, the pull ring 7 is affected by gravity to make the pull rod 6 slide upward, and the pull rod 6 drives the connecting rod 5 to open the bottom of the splint 2, so as to facilitate the cable to fall off. When the pull rod 6 rises, it will pass through the long block to make the piston rod B155 slide upward inside the oil tank B154, so that the oil inside the oil tank A151 is injected into the oil tank B154. At this time, the piston rod B155 contracts toward the inside of the oil tank B154, and the piston rod B155 will drive the plug block when it contracts. 153 contracts inwards, so that the plug 153 loses the limiting effect on the ground wire 13. At this time, the ground wire 13 will fall downward. When the displacement sensor 161 senses the movement of the ground wire 13, it will put the position sensor 164 into working state, and the friction block 167 is moved upward by the electric push rod B166 to make it resist the inner wall of the roller 12. At this time, the plug 168 will automatically reset under the influence of the spring. At this time, the torsion spring will drive the inner ring 162 to rotate synchronously with the roller 12, thereby giving a boost to the ground wire 13 to ensure that the ground wire 13 It will not get stuck during operation. When the inner ring 162 rotates two circles clockwise, the sensing block 165 will contact the position sensor 164 twice, and the electric push rod B166 will drive the friction block 167 to move downward, so that the friction block 167 leaves the inner wall of the roller 12. Then, the friction block 167 will squeeze the insertion rod 168 when moving downward, so that the insertion rod 168 is inserted into the limiting hole on the surface of the turntable 163, and the inner ring 162 is locked, so that the roller 12 can rotate on the surface of the inner ring 162, so that the ground wire 13 can fall off quickly.
