Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction, and in particular to a tube busbar equipotential device based on mechanical arm operation and an application method thereof. Background Art

[0002] The busbar is an important channel for power transmission. Protecting the safety of power production is of great importance. The lines in the substation are exposed outdoors, and the erosion of rain all year round has a certain negative impact on the power supply of the lines. Therefore, the lines need to be inspected and maintained regularly. During the regular inspection and maintenance of the lines, it is often necessary to perform equipotential treatment on the lines to eliminate the risk of electric shock caused by accidental contact between workers and the lines.

[0003] The tube mother support fitting and its equipotential device with patent publication number CN112134039A include: a conductive fixing seat, which is used for conductive fixing on the tube mother support fitting, and the conductive fixing seat has a guide hole; a conductive rod, which is slidably assembled in the guide hole; an elastic member, which is used to apply an elastic force to the conductive rod, and the elastic force is directed toward the tube mother supported by the tube mother support fitting, so that the conductive rod and the tube mother maintain conductive contact; a spring contact finger is provided in the guide hole, so that the conductive rod maintains conductive connection with the conductive fixing seat when sliding in the guide hole; or, it also includes a soft connection, one end of the soft connection is conductively connected to the conductive rod, and the other end of the soft connection is conductively connected to the conductive fixing seat, so that the conductive rod maintains conductive connection with the conductive fixing seat when sliding in the guide hole. The conductive rod overcomes the elastic force of the elastic member and always maintains contact with the tube mother, so as to achieve a reliable electrical connection between the tube mother and the tube mother support fitting.

[0004] The equipotential devices based on the above and similar principles have the disadvantage that it is not convenient to clean the equipotential contact part. When the busbar is exposed to the outside for a long time, there may be dust, rust, oil or other pollutants on the outer wall of the busbar. When the busbar is subjected to equipotential treatment, it is necessary to ensure that the equipotential contact part of the busbar is clean. If the above impurities are present, the quality of electrical contact may be affected, thereby increasing the grounding resistance. The increase in grounding resistance means that there may be a large potential difference in the grounding system. When the equipment fails or leaks electricity, this potential difference may cause the equipment casing to be charged, increasing the risk of electric shock, especially when personnel touch the equipment. Therefore, the present invention is proposed. Summary of the invention

A buffer component for delaying the movement of the limit block is installed between the connecting hose and the arc tube. In the process of limiting the busbar, the main ring is moved down, the busbar contacts the arc block and lifts the arc block. Under the action of the limit spring, the pressure plate compresses the air in the arc tube, and delays the air entering the connecting hose through the buffer component.

After cleaning, the main ring is continued to be moved until the tube busbar is attached to the arc block and the arc block is attached to the main ring. After the attachment is completed, the compressed gas in the airbag is released through the buffer component, and the gas enters the interior of the arc block through the connecting hose to push the first magnetic block and the limit block to move. The limit block is moved to fit the tube busbar to complete the fixed limit of the tube busbar. When the tube busbar is attached to the arc block and the arc block is attached to the main ring, the contact head is attached to the contact point of the tube busbar under the action of the pressure spring to complete the entry into the electric field. The main ring is moved in the opposite direction until the tube busbar is separated from the main ring, and then the electric field can be exited.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

Through the provided adjustment mechanism, the cleaning and contact parts of the tubular busbar by the equipotential mechanism and the cleaning mechanism can be fine-tuned before the cleaning operation, which is conducive to expanding the scope of application.

[0016] At the same time, the position of the busbar can be limited by the setting of the limiting mechanism, so as to avoid the failure of the equipotential treatment due to the shaking of the busbar, which is beneficial to reduce the risk of electric shock. The buffer component set in the limiting mechanism can delay the movement of the limiting block to contact the busbar, which is beneficial to improve the limit, and the limiting block can be a rubber block or an inflatable bag, etc., to increase the applicable shape range of the limit.

Before the equipotential device is put into use, it is necessary to inject an appropriate amount of cleaning agent into the shunt ring 303 in the device, and check the air tightness of the gas circulation in the device to ensure the normal operation of the device.

[0029] like Figure 1-Figure 8As shown, the present invention provides a technical solution: a tubular busbar equipotential device based on a robot arm operation, comprising a main ring 1, the main ring 1 is a semicircular ring with a notch in the middle, the main ring 1 is equipped with a limiting mechanism 2 for fixing and limiting tubular busbars of different shapes and sizes, the main ring 1 is equipped with an equipotential mechanism 4 for performing equipotential treatment on the tubular busbar, the equipotential mechanism 4 is equipped with a cleaning mechanism 3 for cleaning the contact portion between the equipotential mechanism 4 and the tubular busbar, and the main ring 1 is equipped with a contact mechanism for adjusting the contact portion between the equipotential mechanism 4 and the tubular busbar and The cleaning mechanism 3 includes an adjusting mechanism 5 for adjusting the position of the cleaning mechanism 3. The cleaning mechanism 3 includes two ear plates 301. A processing box 304 is installed at the bottom of the ear plate 301. A pumping air pump 302 is installed on the top of the ear plate 301 through a bracket. A vertical pipe connected to the processing box 304 is installed at the output end of the pumping air pump 302. Both ends of the bottom outer wall of the processing box 304 are installed with a nozzle 305 facing the equipotential mechanism 4. A diverter ring 303 for storing cleaning agent is arranged between the two pumping air pumps 302. A material injection pipe is installed on the top of the diverter ring 303. A liquid pipe 306 is installed on the side outer wall, and a liquid spray head 307 facing the bottom center of the main ring 1 is installed at the bottom of the liquid pipe 306. A heating wire 309 is arranged at the bottom of the vertical pipe in the processing box 304. A heat-resistant mounting seat 308 is installed on the outer wall of the heating wire 309. The heating wire 309 is installed in the processing box 304 through the heat-resistant mounting seat 308. When cleaning the pipe busbar, the main ring 1 is moved to the top of the pipe busbar, and the liquid in the diverter ring 303 is sprayed onto the pipe busbar through the liquid spray head 307 and the liquid pipe 306 to complete the cleaning of the outer wall of the pipe busbar. For cleaning of rust or oil stains, the air pump 302 is started to draw gas into the processing box 304, and the gas is blown to the busbar through the nozzle 305 to complete the cleaning of dust attached to the outer wall of the busbar. The gas in the processing box 304 is heated by starting the heating wire 309 in the processing box 304, and the heated gas is blown onto the busbar through the nozzle 305 to complete the drying of the busbar. After cleaning, the busbar is fixed by moving the main ring 1 downward and cooperating with the limiting mechanism 2, and the equipotential treatment of the busbar is completed through the equipotential mechanism 4.

[0030] It should be noted that when the busbar needs to be treated with equal potential, the position of the main ring 1 is adjusted until the busbar is located directly below the main ring 1, and the main ring 1 is moved downward until the busbar is located in the middle of the main ring 1, and the cleaning mechanism 3 is started. The gas is pumped by the air pump 302 to transport the gas to the processing box 304, and the gas can be dried or heated by the electric heating wire 309 provided in the processing box 304, so as to facilitate the subsequent dust removal and drying of the surface of the busbar. The gas in the processing box 304 is sprayed to the surface of the busbar through the spray head 305 to complete the dust removal or drying operation, and the cleaning agent in the diverter ring 303 is sprayed to the surface of the busbar through the liquid spray head 307 and the liquid pipe 306 to clean the surface of the busbar.

After cleaning, continue to move the main ring 1 to the maximum limit, and the position of the pipe busbar can be fixed by the set limiting mechanism 2 to avoid the failure of the equipotential treatment due to the shaking of the pipe busbar, which is beneficial to reduce the risk of electric shock. The set adjustment mechanism 5 can be used to fine-tune the cleaning and contact parts of the pipe busbar by the equipotential mechanism 4 and the cleaning mechanism 3 before the cleaning operation, which is beneficial to expand the scope of application and facilitate use.

[0031] like Figure 1-Figure 4As shown, a square block 6 and a connecting rod 7 are respectively installed at both ends of the bottom outer wall of the main ring 1, and the limiting mechanism 2 includes a rotating seat 201 installed on one side of the inner wall of the square block 6 and the other side of the inner wall of the connecting rod 7. An arc block 202 with a hollow interior is rotatably connected to the rotating seat 201. The two arc blocks 202 are respectively located on both sides of the notch on the main ring 1. An arc rod 207 is installed on the top outer wall of the arc block 202. The arc rod 207 penetrates the outer wall of the main ring 1. The outer wall of the main ring 1 is located at the arc rod 20 A spring receiving tube 209 is installed at 7, and a limit spring 208 surrounding the arc rod 207 is installed between the inner wall of the spring receiving tube 209 and the outer wall of the arc block 202. The arc rod 207 is located at the tube mouth of the spring receiving tube 209 and is fixedly connected to the outer wall with a pressure plate 212. An arc tube 210 is installed on the outer wall of the spring receiving tube 209. The pressure plate 212 fits with the inner wall of the arc tube 210. The outer walls of both sides of the arc block 202 are provided with slide grooves 204, and the slide grooves 204 are slidably inserted. There is a displacement block 215, and a limit block 216 is installed at the bottom of the displacement block 215. A first magnetic block 214 is placed on the inner wall of the arc block 202 at the displacement block 215. The displacement block 215 is embedded with a first magnetic metal block adsorbed by the first magnetic block 214 at one end facing the slide 204. A connecting hose 205 for transmitting gas to move the first magnetic block 214 to drive the limit block 216 to move is installed on the outer wall of the arc block 202. A useful The buffer assembly for delaying the movement of the limit block 216, in the process of limiting the tube busbar, by moving down the main ring 1, the tube busbar contacts the arc block 202 and lifts the arc block 202, under the action of the limit spring 208, the pressure plate 212 compresses the air in the arc tube 210, and delays the air from entering the connecting hose 205 through the buffer assembly, and the air entering the connecting hose 205 pushes the first magnetic block 214 to drive the limit block 216 to move to contact the tube busbar to complete the fixed limiting of the tube busbar.

[0032] It should be noted that when the limiting mechanism 2 is needed, the main ring 1 is moved to make the tube busbar move passively, and the two arc blocks 202 are lifted by the tube busbar. The lifting of the arc blocks 202 squeezes the limiting spring 208. Under the action of the limiting spring 208, when the limiting is cancelled, the two arc blocks 202 are driven to reset. The lifting of the arc blocks 202 moves the arc rod 207. The movement of the arc rod 207 drives the pressure plate 212 to move and compress the air in the arc tube 210, thereby compressing the air. The arc block 202 is retracted into the buffer assembly, and the buffer assembly delays the movement of the limit block 216 to contact the tube busbar. When the arc block 202 is lifted to the maximum limit, the gas is released through the buffer assembly, and the gas enters the interior of the arc block 202 through the connecting hose 205, pushing the first magnetic block 214 to move. Under the action of the magnetic force, the limit block 216 is driven to move to fit the tube busbar to complete the fixed limit of the tube busbar. Otherwise, the fixed limit can be released. The limit block 216 can be a rubber block or an inflatable bag to increase the applicable shape range of the limit.

[0033] like Figure 2 and Figure 4 As shown, the buffer assembly includes an airbag 211 installed on the outer wall of the bottom of the arc tube 210, the arc tube 210 is connected to the airbag 211, the other pipe mouth of the connecting hose 205 is installed on the airbag 211, the connecting hose 205 is installed with a delay air valve 206, and the first magnetic block 214 is installed with a displacement sensor 213.

[0034] It should be noted that when the buffer assembly needs to be used, the compressed gas in the arc tube 210 can be stored through the air bag 211, and the delayed air valve 206 is set to cooperate with the displacement sensor 213. By opening the delayed air valve 206, the gas can be delivered to the connecting hose 205, and by monitoring the displacement of the displacement sensor 213 and closing the delayed air valve 206 according to the displacement, damage to the surface of the busbar due to excessive extrusion force can be avoided. At the same time, the delayed air valve 206 can be replaced by an air pump to achieve the same effect as above, which is determined according to actual usage.

[0035] like Figure 2 , Figure 5 ,and Figure 7As shown, the equipotential mechanism 4 includes a top plate 401 installed between two ear plates 301, the shunt ring 303 is installed on the top plate 401, a vertical groove is opened on the top plate 401, a vertical rod 405 is inserted in the vertical groove, a limiting circular plate is installed on the top outer wall of the vertical rod 405, a detachable contact head 403 is installed on the bottom outer wall of the vertical rod 405, a slide plate is sleeved on the outer wall of the vertical rod 405, a pressure spring 406 surrounding the vertical rod 405 is installed between the top outer wall of the slide plate and the bottom outer wall of the top plate 401, a conductive sheet 404 is inserted between the contact head 403 and the slide plate, a connecting wire 402 is installed on the conductive sheet 404, a fan-shaped groove is opened on the outer wall of the main ring 1, a supporting frame is installed on the outer wall of the main ring 1, and the connecting wire 402 is guided by the fan-shaped groove and placed on the supporting frame.

[0036] It should be noted that when it is necessary to use the equipotential mechanism 4, when the arc block 202 is lifted to fit the inner wall of the main ring 1, under the action of the pressure spring 406, the contact head 403 will be pressed tightly on the busbar, and the contact head 403 cooperates with the conductive sheet 404 and the connecting wire 402 to complete the equipotential treatment of the busbar and complete the entry into the electric field. The fan-shaped groove and the supporting frame are provided to accommodate the connecting wire 402. The conductive sheet 404 is inserted between the provided slide plate, the pressure spring 406 and the contact head 403 and the slide plate, so that the conductive sheet 404 can be easily disassembled. The contact head 403 is inserted on the vertical rod 405 by threaded rotation, and the contact head 403 can also be disassembled, which is convenient for subsequent maintenance personnel to maintain the device.

[0038] It should be noted that when the adjustment mechanism 5 needs to be used, the second magnetic block 507 is driven to move by starting the driving component, and the moving block 502 is driven to move by the effect of magnetic attraction, thereby adjusting the positions of the cleaning mechanism 3 and the equipotential mechanism 4.

[0039] like Figure 5 and Figure 7As shown, the driving assembly includes a connecting pipe 503 installed at the outer wall port of the annular block 501, an adjusting hose 504 connected to the vertical pipe is installed on the connecting pipe 503, a first air valve 505 is installed on the outer wall of the adjusting hose 504, and a second air valve 506 is installed at the bottom of the vertical pipe. The second magnetic block 507 can be driven to move by pumping and inflating the air pump 302 in conjunction with the adjusting hose 504.

[0040] It should be noted that when the driving assembly needs to be used, by closing the second air valve 506 and turning on the pumping air pump 302, the air pressure change of the gas inside the annular block 501 can be controlled by the pumping and inflating of the air pump 302 in coordination with the connecting pipe 503 and the adjusting hose 504, and then the position of the second magnetic block 507 can be adjusted, thereby adjusting the position of the cleaning mechanism 3 and the equipotential mechanism 4, which is beneficial for fine-tuning the contact position between the equipotential mechanism 4 and the pipe busbar according to usage requirements.
