Description

Technical Field

[0001] The present invention relates to the technical field of grounding wire disassembly and assembly, and in particular to an unmanned aerial vehicle (UAV) hanging and mounted grounding device and a method of using the same. Background Art

[0002] At present, in the power outage construction work of the distribution network, the installation and removal of the grounding wire mainly relies on manual climbing of the pole tower. The whole installation and removal process is time-consuming, labor-intensive, inefficient, and often accompanied by risks such as falling from height and electric shock. There is also a method of installing the grounding wire using an extended operating rod, and the operators can complete the installation and removal of the grounding wire on the ground, but the extended operating rod is too heavy with the grounding wire attached, so that the whole operation requires multiple people to complete. It is laborious and unsafe to lift the grounding wire. At the same time, due to the influence of the terrain, the practical scenarios of installing the grounding wire using the extended operating rod are limited, and it is not applicable in most places.

[0003] These traditional methods are not only inefficient, but also pose safety hazards when operating in complex environments. With the rapid development of drone technology, the research on using drones to hang grounding wires has gradually become an important technical direction. However, under the existing technical background, the demand for hanging grounding wires on drones still faces the following technical problems: 1. There are high requirements for the model and performance of the drone and the technical level of the operator; 2. The connection of the grounding device is unstable, resulting in poor hanging effect, affecting the safety and reliability of the operation; 3. Complex and repetitive operations are required when removing the grounding wire, which increases the complexity and workload of the operation. In order to solve the above technical problems, we proposed a drone-dropped grounding device and its use method. Summary of the invention

[0004] The purpose of the present invention is to provide a UAV hanging type grounding device and a method of using the same, so as to solve the problems of low efficiency, low safety and poor adaptability of the existing traditional hanging grounding wire method.

[0005] In order to solve the above technical problems, the present invention provides a UAV drop-hanging grounding device and a method for using the device, comprising: a housing, the housing comprising a mounting seat and a rod body arranged on one side of the mounting seat; A clamping mechanism, the clamping mechanism is arranged above the mounting seat, and comprises a pair of clamping jaws, a pair of spring sheets arranged between the clamping jaws, an elastic member arranged between the clamping jaws and the spring sheets, and a tensioning member arranged outside the clamping jaws, and the clamping mechanism is used to clamp the cable; A locking mechanism, the locking mechanism comprising a top block, a connecting rod disposed below the top block, a compression spring surrounding the connecting rod, and a locking assembly disposed below the connecting rod, the locking mechanism being used to lock the clamping mechanism; A wire hanging mechanism, the wire hanging mechanism comprising a wire pulling rod disposed on both sides of the mounting seat, and a wire pulling hole opened at one end of the wire pulling rod for connecting a wire pulling device; The locking assembly includes a limiter, a cone ring arranged on one side of the limiter, a tail block arranged on one side of the cone ring, a spring groove opened on the side of the tail block facing the cone ring, and a locking spring arranged between the spring groove and the cone ring.

[0006] Preferably, the rod body includes a plug hole arranged inside the rod body, plug block grooves arranged on both sides of the rod body, and a grounding terminal arranged at the tail of the rod body.

[0007] Preferably, the locking assembly further includes a limiting plug block disposed in the plug block groove, and a plug block spring surrounding the limiting plug block.

[0008] Preferably, the mounting seat is hinged to the clamping claw via a pair of first hinged rods.

[0009] Preferably, the clamp includes an insertion block, a spring window disposed on one side of the insertion block, a second hinge rod disposed below the spring window, a first hinge hole disposed on one side of the second hinge rod, an abutment plate disposed at the bottom of the clamp, and an abutment curved surface disposed above the abutment plate; The abutment plate is pressed against the top block, and the abutment position of the abutment plate is the bottom edge of the arc.

[0010] Preferably, the tensioning member includes a pair of fixing seats arranged on the mounting seat and the clamping jaw, and a tension spring connected between the fixing seats.

[0011] Preferably, the spring sheet material is a conductive metal and is connected to the ground terminal.

[0012] Preferably, the bottom of the tail block is an arc bottom edge.

[0013] Preferably, the limiting plug is in the shape of a right triangle with one end facing the rod body and the right angle side facing downward and the right angle side parallel to the bottom side of the limiting plug, so that the limiting plug can be inserted into the gap between the cone ring and the tail block.

[0014] The present invention also provides a method for using a UAV drop-hanging grounding device, comprising the following steps: Step A: Install the ground wire on the drone; Step A1: The unhooking device is mounted on the drone, and an acoustic and optical tester is also mounted on the bottom of the drone. The test end of the acoustic and optical tester falls naturally, and the unhooking device is connected to one end of the traction rope. The unhooking device is controlled by remote control, and the traction rope is controlled to fall to the other side of the cable by opening and closing the remote control dispenser; Step A2: After loading is completed, the drone is remotely operated to rise to a height higher than the cable to be grounded. After exceeding the height, the drone passes over the cable, and the sound and light tester contacts the cable to test the power. After confirming that the power is off and safe, the remote control unhooking device unhooks and lowers the traction rope; Step A3: After the traction rope falls freely, connect the drone-throwing hanging grounding device. The drone-throwing hanging grounding device is in the open state, that is, the claws are separated, and the traction rope is divided into two strands, which are respectively connected to the rope perforated lock buckles on both sides. At the same time, the grounding end is fixedly connected to the grounding wire by bolts; Step A4: The construction personnel pull the traction rope on the other side of the UAV hanging grounding device, and pull the device onto the cable until the cable contacts the top block. Continue to pull, the cable will squeeze the top block to compress the compression spring, and at the same time, the cone ring and the tail block are pressed down along the rod body until they touch the limit plug. Since the bottom of the tail block is an arc bottom edge, the contact part with the limit plug is a bevel edge, so that the limit plug passes through the tail block, and finally the limit plug is engaged in the gap between the cone ring and the tail block to achieve locking. At this time, the claws at the high position will gradually move closer until the top block moves to between the two abutment plates to close and lock the claws, so that the cable is fixed between the two spring pieces, thereby completing the grounding; Step A5: After the lock is completed, ground the other end of the ground wire; Step B: Construction work; Step B1: Perform electrical construction work such as installation, removal, maintenance or replacement of equipment according to the construction plan; Step C: Remove the ground wire from the drone; Step C1: When removing the ground wire, just continue to pull the traction rope. At this time, the top block continues to press down, and the limit plug continues to fit the cone ring and move to the conical narrow end of the cone ring. After loosening, the top block resets under the elastic force of the compression spring, and the limit plug reversely squeezes the locking spring to make the cone ring close to the tail block. The gap between the cone ring and the tail block disappears, and the limit plugs on both sides directly pass through the tail block and disengage from the locking mechanism. The top block resets, and the claws open under the traction of the tensioning pieces on both sides. The cable is disengaged and clamped, and the disassembly is completed; Step C2: After detachment, recycle the traction rope and the UAV drop-mounted grounding device.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The drone-dropped grounding device and the method for using the device utilize drones to install and remove grounding wires, which significantly reduces the time and labor intensity of traditional human climbing of pole towers, thereby improving the work efficiency. The operators do not need to climb high altitudes, which improves the safety of the work. At the same time, the device can be used in complex terrains and environments, which improves the flexibility and feasibility of the work. 2. The UAV hanging grounding device of the present invention can lock and ground the cable through the design of the clamp and the spring, and use the locking mechanism to control the opening and closing of the clamp. During installation, it is only necessary to pull the traction rope to squeeze the cable and the top block, and insert the limit plug into the gap between the cone ring and the tail block, so as to stably maintain the clamping of the clamp and lock the cable. During disassembly, there is no need for excessive repeated operations. The traction rope is continued to be pulled to move the limit plug to the narrow end of the cone ring. After loosening, the limit plug is reversely squeezed to squeeze the cone ring, and the limit plug will directly pass through the tail block and disengage from the locking mechanism to achieve disassembly. This process is simple to operate, reduces the complexity and workload of the operation, and has low requirements on the technical level of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The rod body 102 includes a socket 102a arranged inside it, a plug-in block groove 102b arranged on both sides of the rod body 102, and a grounding end 102c arranged at the tail of the rod body 102; the mounting seat 101 is hinged to the clamping jaw 201 through a pair of first hinged rods 101a; the clamping jaw 201 includes an insertion block 201a, a spring window 201b arranged on one side of the insertion block 201a, a second hinged rod 201c arranged below the spring window 201b, a first hinge hole 201d arranged on one side of the second hinged rod 201c, a contact plate 201e arranged at the bottom of the clamping jaw 201, and a contact curved surface 201f arranged above the contact plate 201e; the contact plate 201e is abutted against the top block 301, and the contact position of the contact plate 201e is the bottom edge of the arc.

[0023] The tensioning member 204 includes a pair of fixing seats 204a arranged on the mounting seat 101 and the clamping jaw 201, and a tension spring 204b connected between the fixing seats 204a; the material of the spring piece 202 is conductive metal and is conductive with the grounding terminal 102c; the bottom of the tail block 303c is an arc bottom edge; the limiting plug 303f has one end facing the inside of the rod body 102 and is in the shape of a right-angled triangle with the right-angled side facing downward and the right-angled side parallel to the bottom edge of the limiting plug 303f, so that the limiting plug 303f can be inserted into the gap between the cone ring 303b and the tail block 303c.

[0024] It should be noted that the device is made of stainless steel, and the mounting base 101 is fixedly installed above the rod body 102. The mounting base 101 is in the shape of a groove opening upward, and two pairs of hinge holes are opened on the mounting base 101. A pair of first hinge rods 101a are hinged to the hinge holes, and the first hinge rods 101a are also hinged to the first hinge hole 201d on the clamp 201. In this way, the clamp mechanism 2 is installed on the shell 1.

[0025] Preferably, the rod body 102 is a cylindrical rod, which has a socket 102a that is opened from top to bottom but does not penetrate through it. The socket 102a is used to insert the connecting rod 302 and the locking assembly 303 into the rod body 102. Block grooves 102b are fixedly installed on both sides of the rod body 102. Limiting blocks 303f for limiting the locking assembly 303 are installed in the block grooves 102b. The limiting block 303f includes an angled plug. Through the block spring 303g on the other side of the limiting block 303f, the elastic force of the block spring 303g squeezes the limiting block 303f to insert the angled plug into the gap between the cone ring 303b and the tail block 303c to lock the locking assembly 303. The grounding terminal 102c is located at the bottom of the rod body 102, and two bolt holes are provided on its surface for fixed connection with the conductive sheet of the grounding wire by bolts.

[0026] Preferably, the clamping jaws 201 have a pair of two, and the spring sheet 202 is hinged on the second hinge rod 201c. The spring sheet 202 is an arc convex toward the clamped cable, which is used to increase the contact area between the cable and the spring sheet 202. The two ends of the elastic member 203 are respectively fixed on the inner side of the clamping jaw 201 and the outer side of the spring sheet 202. The elastic member 203 squeezes the position of the spring sheet 202 so that the spring sheet 202 can be tightly attached to the clamped cable. The jaws of the two clamping jaws 201 are complementary. When the clamping jaws 201 are closed, they are used to lock the cable in the clamping jaws 201 and fix the position of the cable through the spring sheets 202 on both sides of the cable, so that the spring sheet is close to the cable, thereby improving the clamping effect. The spring sheet 202 is a conductive metal that is conductive to the grounding terminal 102c, and being close to the cable can also improve the conductive grounding effect.

[0027] Preferably, the spring sheet window 201b is used to provide a larger activity space for the spring sheet 202, and the abutment plate 201e is located at the bottom of the clamp 201. The abutment plates 201e of the clamps 201 on both sides are staggered and surround the two sides of the connecting rod 302. In this way, when the clamp 201 is separated, the abutment plates 201e on both sides will not collide with each other, and the abutment plates 201e can abut on both sides of the top block 301 at the same time. When the top block 301 is located between the abutment plates 201e, the clamp mechanism 2 is in a closed and locked state. When the top block 301 is pressed down, it will disengage from the abutment plate 201e, so that the clamp 201 is opened under the tension of the tensioning member 204. The abutment curved surface 201f is a curved surface, which makes the process of the top block 301 disengaging from and inserting into the two abutment plates 201e smoother.

[0028] Preferably, the tensioning member 203 is composed of two spring piles and a slender tensioning spring, and the spring piles are fixedly mounted on the outer wall of the clamp 201 and the outer wall of the mounting seat 101, so that the clamp 201 is in an open state when the device is not working, and at the same time ensures that the clamp 201 will automatically open and directly disengage from the cable after the limit plug 303f is disengaged from the locking assembly 303.

[0029] Preferably, there are two rope-pulling rods 401, which are vertically fixed on both sides of the mounting base 101 in a straight line. Rope-pulling holes 402 are provided at the ends of the rope-pulling rods 401. The traction rope passes through the rope-pulling holes 402 and is fixed to both ends of the device, so as to be used to pull the device from the outside and lift it to the position of the cable to be grounded.

[0030] Preferably, the contact surfaces between the two sides of the top block 301 and the abutment plate 201e are also arc-shaped curves, the connecting rod 302 is fixed to the bottom of the top block 301, one end of the compression spring 303 is fixed to the bottom of the top block 301, and the other end is fixed to the mounting seat 101, surrounding the outer periphery of the connecting rod 302, and the compression spring 303 will squeeze the top block to open the clamping jaw 201 in a normal state, that is, the clamping jaw 201 of this device is open in a normal state, and the other end of the connecting rod 302 is fixed to the limit member 303a, and the limit member 303a is used to limit the position of the locking assembly 303, and there is another section of the connecting rod 302 below the limit member 303a, and the outside of this section of the connecting rod 302 is a cone ring 303b, a locking spring 303 from top to bottom. e, spring groove 303d, tail block 303c, cone ring 303b is an annular structure with a conical cross-section, cone ring 303b is arranged with a small cone mouth at the upper end and a large cone mouth at the lower end, the small cone mouth at the upper end faces the limit member 303a, the lower cone mouth is fixedly connected to the upper end of the lock spring 303e, and the lower end of the lock spring 303e is fixedly installed in the spring groove 303d, the spring groove 303d is a groove opened above the tail block 303c, the spring groove 303d is used to make the lock spring 303e completely compressed into the spring groove 303d when the unlocking device is unlocked, so that the cone ring 303b and the tail block 303c are completely fitted, and the limiting plug 303f can smoothly pass through the tail block to disengage from the lock assembly 303 to achieve unlocking.

[0031] In summary, the UAV hanging type grounding device of the present invention can lock and ground the cable through the design of the clamp and the spring, and use the locking mechanism to control the opening and closing of the clamp. During installation, it is only necessary to pull the traction rope to squeeze the cable and the top block against each other, and insert the limit plug into the gap between the cone ring and the tail block, so as to stably maintain the clamping of the clamp and lock the cable. During disassembly, there is no need for excessive repeated operations. The traction rope is continued to be pulled to move the limit plug to the narrow end of the cone ring. After loosening, the limit plug is reversely squeezed to squeeze the cone ring, and the limit plug will directly pass through the tail block and disengage from the locking mechanism to achieve disassembly. This process does not require complicated operations, reduces the complexity and workload of the operation, and has low requirements on the technical level of the operator.

[0032] Embodiment 2 The present invention provides a method for using a UAV drop-mounted grounding device, please refer to Figures 1 to 5 , including the following steps: Step A: Install the ground wire on the drone; Step A1: The unhooking device is mounted on the drone, and an acoustic and optical tester is also mounted on the bottom of the drone. The test end of the acoustic and optical tester falls naturally, and the unhooking device is connected to one end of the traction rope. The unhooking device is controlled by remote control, and the traction rope is controlled to fall to the other side of the cable by opening and closing the remote control dispenser; Step A2: After loading is completed, the drone is remotely operated to rise to a height higher than the cable to be grounded. After exceeding the height, the drone passes over the cable, and the sound and light tester contacts the cable to test the power. After confirming that the power is off and safe, the remote control unhooking device unhooks and lowers the traction rope; Step A3: After the traction rope falls freely, the drone-throwing grounding device is connected. The drone-throwing grounding device is in an open state, that is, the claws 201 are separated, and the traction rope is divided into two strands, which are respectively connected to the pull rope through holes 402 on both sides by locks, and the grounding end 102c is fixedly connected to the grounding wire by bolts; Step A4: The construction personnel pull the traction rope on the other side of the UAV hanging grounding device, and pull the device onto the cable until the cable contacts the top block 301. Continue to pull, the cable will squeeze the top block 301 to compress the compression spring 303, and at the same time, the cone ring 303b and the tail block 303c are pressed down along the rod body 2 until they touch the limit plug 303f. Since the bottom of the tail block 303c is an arc bottom edge, and the contact part with the limit plug 303f is a bevel edge, the limit plug 303f passes through the tail block 303c, and finally the limit plug 303f is engaged in the gap between the cone ring 303b and the tail block 303c to achieve locking. At this time, the high claw 201 will gradually move closer until the top block 301 moves to between the two abutment plates 201e to close and lock the claw 201, so that the cable is fixed between the two spring pieces 202, thereby completing the grounding; Step A5: After the lock is completed, ground the other end of the ground wire; Step B: Construction work; Step B1: Perform electrical construction work such as installation, removal, maintenance or replacement of equipment according to the construction plan; Step C: Remove the ground wire from the drone; Step C1: When removing the ground wire, just continue to pull the traction rope. At this time, the top block 301 continues to press down, and the limit plug 303f continues to fit the cone ring 303b and moves to the conical narrow end of the cone ring 303b. After loosening, the top block 301 is reset under the elastic force of the compression spring 303, and the limit plug 303f will reversely squeeze the locking spring 303e, so that the cone ring 303b is close to the tail block 303c, and the gap between the cone ring 303b and the tail block 303c disappears. The limit plugs 303f on both sides will directly pass through the tail block 303c and disengage from the locking mechanism 3, the top block 301 is reset, and the claws 201 are opened under the traction of the tensioning members 204 on both sides, and the cable is disengaged and clamped, and the disassembly is completed; Step C2: After detachment, recycle the traction rope and the UAV drop-mounted grounding device.

[0033] In summary, the drone-dropped grounding device and its use method of the present invention utilize drones to install and remove grounding wires, which significantly reduces the time and labor intensity of traditional manual climbing of pole towers, thereby improving work efficiency. Operators do not need to climb high altitudes, which improves the safety of operations. At the same time, the device can be used in complex terrain and environments, improving the flexibility and feasibility of operations.

9. A method for using the UAV drop-hanging grounding device as claimed in claim 8, characterized in that: The end of the limiting plug (303f) facing the inside of the rod body (102) is in the shape of a right-angled triangle with the right-angled side facing downwards and the right-angled side being parallel to the bottom side of the limiting plug (303f), so that the limiting plug (303f) can be inserted into the gap between the cone ring (303b) and the tail block (303c).

10. A method for using the UAV drop-hanging grounding device as claimed in claim 9, characterized in that: The steps include: Step A: Install the ground wire on the drone; Step A1: The unhooking device is mounted on the drone, and an acoustic and optical tester is also mounted on the bottom of the drone. The test end of the acoustic and optical tester falls naturally, and the unhooking device is connected to one end of the traction rope. The unhooking device is controlled by remote control, and the traction rope is controlled to fall to the other side of the cable by opening and closing the remote control dispenser; Step A2: After loading is completed, the drone is remotely operated to rise to a height higher than the cable to be grounded. After exceeding the height, the drone passes over the cable, and the sound and light tester contacts the cable to test the power. After confirming that the power is off and safe, the remote control unhooking device unhooks and lowers the traction rope; Step A3: After the traction rope falls freely, the drone-dispensing grounding device is connected. The drone-dispensing grounding device is in an open state, that is, the claws (201) are separated, and the traction rope is divided into two strands, which are respectively connected to the pull rope through holes (402) on both sides, and the grounding end (102c) is fixedly connected to the grounding wire by bolts; Step A4: The construction personnel pull the traction rope on the other side of the drone drop-hanging grounding device to pull the device onto the cable until the cable contacts the top block (301). The cable continues to push the top block (301) to compress the compression spring (303). At the same time, the cone ring (303b) and the tail block (303c) are pressed down along the rod body (2) until they touch the limit plug (303f). Since the bottom of the tail block (303c) is a circular arc bottom edge , the contact portion with the limit plug (303f) is a beveled edge, so that the limit plug (303f) passes through the tail block (303c), and finally the limit plug (303f) is engaged in the gap between the cone ring (303b) and the tail block (303c) to achieve locking. At this time, the claws (201) at the upper position will gradually move closer until the top block (301) moves to between the two abutment plates (201e) to close and lock the claws (201), and the cable is fixed between the two spring pieces (202), completing the grounding; Step A5: After the lock is completed, ground the other end of the ground wire; Step B: Construction work; Step B1: Perform electrical construction work such as installation, removal, maintenance or replacement of equipment according to the construction plan; Step C: Remove the ground wire from the drone; Step C1: When removing the ground wire, it is only necessary to continue to pull the traction rope. At this time, the top block (301) continues to be pressed downward, and the limit plug (303f) continues to fit the cone ring (303b) and move to the conical narrow end of the cone ring (303b). After loosening, the top block (301) is reset under the elastic force of the compression spring (303), and the limit plug (303f) will reversely squeeze the locking spring (303e) so that the cone ring (303b) is close to the tail block (303c). The gap between the cone ring (303b) and the tail block (303c) disappears, and the limit plugs (303f) on both sides will directly pass through the tail block (303c) and disengage from the locking mechanism (3), the top block (301) is reset, and the claws (201) are opened under the traction of the tensioning members (204) on both sides, and the cable is disengaged from the clamping, and the disassembly is completed; Step C2: After the cable is detached, the traction rope and the drone-thrown grounding device are recovered.
