Description

Technical Field

[0001] The invention belongs to the technical field of electric equipment, and in particular relates to an electric equipment maintenance auxiliary device with a suspension function. Background Art

[0002] Power equipment is an electricity production and consumption system consisting of power generation, transmission, transformation, distribution and consumption. It converts primary energy from nature into electricity through power generation devices, and then supplies electricity to various users through transmission, transformation and distribution.

[0003] When repairing power equipment, it is necessary to ground its cables. This requires an auxiliary device for power equipment maintenance with a hanging function, namely a drone grounding wire device.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] The present invention provides an auxiliary device for repairing electric equipment with a suspension function, such as Figures 1 to 7 As shown, it includes a bracket 1, a hook 2 is provided on the top of the bracket 1, and a clamp 3 is symmetrically provided inside the bracket 1. Among them, the bracket 1 is a UAV grounding wire device in the prior art, and the clamp 3 is a clamp for clamping the cable on the UAV grounding wire device in the prior art.

[0028] Furthermore, the bracket 1 is provided with a component for driving the movement of the splint 3. An arc groove is provided on the inner side of the splint 3, and an arc piece is provided in the arc groove. The arc piece is made of the same material as the splint 3. A notch connected to the arc groove is symmetrically provided on the inner side of the splint 3. A mounting bracket 4 is fixedly installed on the two side edges of the notch on the splint 3. A screw rod 5 is rotatably installed on the two opposite mounting brackets 4 respectively. The thread directions of the screw rods 5 on the left and right sides are set in opposite directions. Slide blocks 6 are symmetrically threaded on the two screw rods 5. An arc plate 7 is provided between the two opposite slide blocks 6. A slide groove is provided on the side of the slider 6 close to the arc plate 7. A connecting block 8 is slidably installed in the slide groove. The connecting block 8 is fixedly connected to the arc plate 7. The side of the connecting block 8 close to the splint 3 is fixedly connected to the inner wall of the slide groove through a first spring 9. A driving component for driving the screw rod 5 to rotate is provided on the outside, and a wiping component for wiping water drops on the surface of the cable is provided on the arc plate 7.

[0029] When in use, the drone cooperates with the hook 2 to move the bracket 1 to the cable, and the drone detaches from the hook 2. At this time, the component on the bracket 1 drives the splint 3 to move close to the cable. As the splint 3 moves, the wiping component collides with the cable, and then the cable fits with the curved plate 7. At this time, the splint 3 cannot continue to move, and the driving component drives the screw rod 5 to rotate and drive a pair of sliders 6 to move away from each other, thereby driving the connecting block 8 and the curved plate 7 to move, so that the wiping component wipes the water droplets on the surface of the cable. When the curved plate 7 detaches from the curved groove, at this time, with the squeezing of the splint 3, the curved plate 7 moves with the connecting block 8 and compresses the first spring 9, and finally the surface of the curved plate 7 is flush with the curved groove. At this time, the cable collides with the curved sheet in the splint 3. Due to the wiping of the water droplets on the surface of the cable, the surface of the cable is dry and clean. Therefore, the friction between the curved sheet and the surface of the cable is large, which makes the splint 3 clamp the cable more stably, so that when working in windy weather, there will be no situation where the bracket 1 is blown by the wind and rotates around the cable due to the small friction between the water droplets between the cable and the splint 3.

[0030] like Figure 2 As shown, the driving assembly includes a first motor 27 fixedly connected to a side mounting frame 4, one end of the output shaft of the first motor 27 is fixedly connected to one end of the screw rod 5, and a remote control assembly for controlling the rotation of the first motor 27 is provided on the bracket 1. The remote control assembly is a remote control assembly in the prior art and can realize a remote control function.

[0031] The output shaft of the first motor 27 is remotely controlled by the remote control component to rotate with the lead screw 5, thereby driving the lead screw 5.

[0032] like Figures 2 to 6 As shown, the wiping assembly includes a cloth strip 10, a cavity is provided inside the arc plate 7, a rectangular rod 11 is symmetrically rotatably installed in the cavity, a winding drum 12 is sleeved on the outside of the rectangular rod 11, and an outlet is symmetrically provided on the side of the arc plate 7 away from the arc groove, both ends of the cloth strip 10 pass through the outlet and are fixedly connected with the corresponding winding drum 12, the cloth strip 10 is wound on the winding drum 12 on one side, and a rotating assembly for driving the rotation of the rectangular rod 11 on one side is provided on the outside, and a cover plate 15 is provided on the opposite side of the two arc plates 7, the cover plate 15 closes the outlet and one side of the cavity, and the cover plate 15 is fixed to the arc plate 7 by screws.

[0033] The screw is turned to separate the cover plate 15 from the curved plate 7, and the reel 12 can be removed from the rectangular rod 11 to replace the cloth strip 10. The cable and the cloth strip 10 are in conflict with each other, so that the cloth strip 10 is pulled, and the cloth strip 10 is released from the reel 12 on one side. Finally, the cloth strip 10 is in conflict with the curved plate 7 and the cable. When the clamping plate 3 leaves the cable, the rotating assembly drives the rectangular rod 11 to rotate, so that the reel 12 rotates, thereby rolling up the damp and contaminated cloth strip 10 after wiping, and releasing the clean and dry cloth strip 10, thereby realizing the switching of the cloth strip 10, so that the clean and dry cloth strip 10 is located at the curved plate 7, ensuring subsequent normal use.

[0034] like Figures 2 to 6 As shown, the rotating assembly includes a second motor 28 fixedly connected to the side of the arc plate 7 away from the cover plate 15, one end of the output shaft of the second motor 28 is fixedly connected to one end of the upper rectangular rod 11, the second motor 28 is a servo motor, and its output shaft can be locked. A push switch 14 is provided on the inner wall of the side of the slide away from the connecting block 8, and a controller is provided in the slide groove for cooperating with the push switch 14 to control the start of the second motor 28, and a pressure rod 13 is fixedly connected to the side of the connecting block 8 close to the push switch 14.

[0035] When the arc plate 7 is separated from the arc groove, it is squeezed, and the arc plate 7 moves with the connecting block 8 and compresses the first spring 9. The connecting block 8 moves with the pressure rod 13 to press the press switch 14. When the clamping plate 3 is separated from the cable, the compressed first spring 9 releases the force to reset the connecting block 8, the pressure rod 13 and the arc plate 7. At this time, the controller controls the output shaft of the second motor 28 to rotate with the rectangular rod 11, thereby driving the rectangular rod 11.

[0036] like Figures 3 to 7 As shown, an arc-shaped opening is opened on the cover plate 15, an arc-shaped strip 16 is arranged in the arc-shaped opening, a cavity is arranged inside the arc-shaped strip 16, a spray hole 18 connected with the cavity is arranged on the side of the arc-shaped strip 16 away from the arc-shaped groove, blocks 17 are fixedly installed at both ends of the arc-shaped strip 16, the blocks 17 are located in the cavity, a second spring 19 is fixedly connected to the side of the arc-shaped strip 16 away from the cover plate 15, and a gas injection component for injecting gas into the arc-shaped strip 16 is arranged on the outside.

[0037] When the two arc plates 7 are separated, the second spring 19 releases its force to move the arc strip 16, so that the spray hole 18 on the arc strip 16 extends to the outside of the arc plate 7. As the arc plate 7 moves, the air injection assembly injects air into the cavity, so that the air is sprayed out through the spray hole 18 to blow on the cable surface, further improving the drying process of the cable surface.

[0038] like Figures 3 to 7As shown, the gas injection assembly includes a cylinder body 20, the top wall of the notch is provided with a groove, the cylinder body 20 is fixed in the groove, the top of the cylinder body 20 is provided with an air intake pipe 21 connected with the interior thereof, the upper outer portion of the cylinder body 20 is provided with an air outlet pipe 22 connected with the interior thereof, the interiors of the air intake pipe 21 and the air outlet pipe 22 are both provided with a one-way valve, the air outlet pipe 22 is connected with the interior of the arc strip 16 through a hose 23 passing through the arc plate 7, and the interior of the cylinder body 20 is provided with an extrusion assembly for squeezing the internal air outward.

[0039] When the two curved plates 7 are separated, the slider 6 cooperates with the extrusion assembly to squeeze the air in the cylinder 20 outward during movement. At this time, the one-way valve located in the intake pipe 21 is closed, and the one-way valve located in the outlet pipe 22 is opened. The air in the cylinder 20 enters the cavity through the outlet pipe 22 and the hose 23 and is then ejected through the spray hole 18. When the curved plate 7 is reset, the slider 6 cooperates with the extrusion assembly working in the reverse direction to inhale air into the cylinder 20. At this time, the one-way valve located in the intake pipe 21 is opened, and the one-way valve located in the outlet pipe 22 is closed, and the outside air enters the cylinder 20 through the intake pipe 21.

[0040] like Figure 7 As shown, the extrusion assembly includes a plug plate 24 arranged in the cylinder body 20, the top of the plug plate 24 is fixed to the inner wall of the cylinder body 20 through a third spring 25, and the bottom of the plug plate 24 is fixedly connected to a push plate 26 through a connecting rod passing through the cylinder body 20, and the push plate 26 is in contact with the slider 6.

[0041] The push plate 26 is specifically configured as a plate-shaped component with an inclined surface at the bottom. The height of the bottom of the push plate 26 close to the slider 6 is higher than the height of the bottom of the push plate 26 away from the slider 6 .

[0042] The two arc plates 7 are separated. At this time, the slider 6 cooperates with the inclined surface to squeeze the push plate 26 to make it rise with the connecting rod and the plug plate 24, compressing the third spring 25 to make it deform and generate a force. At this time, the air in the cylinder body 20 is squeezed outward. When the arc plate 7 is reset, as the slider 6 is reset, the third spring 25 releases the force to reset the plug plate 24, the connecting rod and the push plate 26, and air is sucked into the cylinder body 20.

[0043] Working principle: When in use, the drone cooperates with the hook 2 to move the bracket 1 to the cable, and the drone is detached from the hook 2. At this time, the component on the bracket 1 drives the clamping plate 3 to move close to the cable. With the movement of the clamping plate 3, the cable and the cloth strip 10 are in conflict, so that the cloth strip 10 is pulled, so that the cloth strip 10 is released from the winding drum 12 on one side. Finally, the cloth strip 10 conflicts with the arc plate 7 and the cable. Then the cable and the arc plate 7 are fitted. At this time, the clamping plate 3 cannot continue to move, and the output shaft of the first motor 27 is remotely controlled by the remote control component. The rotation drives the screw rod 5 to rotate, so that the pair of sliders 6 move away from each other, thereby driving the connecting block 8 and the arc plate 7 to move, so that the cloth strip 10 wipes the water drops on the surface of the cable. When the arc plate 7 is separated from the arc groove, the arc plate 7 moves with the connecting block 8 and compresses the first spring 9 as the clamping plate 3 is squeezed, and finally the surface of the arc plate 7 is flush with the arc groove. At this time, the cable is in conflict with the arc sheet in the clamping plate 3. Due to the wiping of the water drops on the surface of the cable, the surface of the cable is dry and clean. Therefore, the friction between the arc sheet and the surface of the cable is large, which makes the clamping plate 3 clamp the cable more stably, so that the bracket 1 is blown around the cable by the wind due to the small friction force caused by the water drops between the cable and the clamping plate 3 during operation in strong winds. When the arc plate 7 is separated from the arc groove, it is squeezed at this time, and the arc plate 7 moves with the connecting block 8 and compresses the first spring 9. The connecting block 8 moves with the pressure rod 13 to press the press switch 14. When the clamping plate 3 is reset and separated from the cable, the compressed first spring 9 is released. The force brings the connection block 8, the pressure rod 13, and the arc plate 7 back to their original positions. At this time, the controller controls the output shaft of the second motor 28 to bring the rectangular rod 11 to rotate, so that the winding drum 12 is rotated, so that the wet and contaminated cloth strips 10 after wiping are rolled up, and the clean and dry cloth strips 10 are released, so as to realize the switching of the cloth strips 10, so that the clean and dry cloth strips 10 are located at the arc plate 7, ensuring the subsequent normal use. Then, the first motor 27 is controlled to bring the screw rod 5 to rotate and reset, so that the driving slider 6 and the arc plate 7 are reset;When the two arc plates 7 are separated, the second spring 19 releases its force to move the arc strip 16, so that the spray hole 18 on the arc strip 16 extends outside the arc plate 7. As the arc plate 7 moves, the slider 6 moves and cooperates with the inclined surface to squeeze the push plate 26 to make it rise with the connecting rod and the plug plate 24, compressing the third spring 25 to deform it and generate a force. At this time, the air in the cylinder 20 is squeezed outward. At this time, the one-way valve in the intake pipe 21 is closed, and the one-way valve in the outlet pipe 22 is opened. The air in the cylinder 20 passes through the outlet pipe 22. The tube 22 and the hose 23 enter the cavity and then spray out through the spray hole 18, so that the air sprays out through the spray hole 18 to blow air on the cable surface, further improving the drying treatment of the cable surface. When the arc plate 7 is reset, along with the reset of the slider 6, the third spring 25 releases the force to reset the plug plate 24, the connecting rod, and the push plate 26, and then air is sucked into the cylinder 20. At this time, the one-way valve in the suction pipe 21 is opened, and the one-way valve in the outlet pipe 22 is closed, and the outside air enters the cylinder 20 through the suction pipe 21. ;

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
