Description

Technical Field

[0001] This invention relates to the field of gas-insulated switchgear technology, and in particular to a 35kV sulfur hexafluoride gas-insulated switchgear with good heat dissipation. Background Technology

[0002] Sulfur hexafluoride is an excellent gas insulator and is widely used for gas insulation in electronic and electrical equipment. Its typical application is as gas insulation in high-voltage switchgear in power transmission and transformation stations and power plants. Gas-filled switchgear is suitable for small secondary substations, switching stations, prefabricated substations, residential areas, industrial and mining enterprises, and large shopping malls in power systems. It is especially suitable for airports, subways, railways and other occasions with high power requirements.

[0003] In the prior art, such as Chinese Patent No. CN113471853A, a combined sulfur hexafluoride gas-filled ring main unit is disclosed, including a base plate and a gas-filled ring main unit body. The gas-filled ring main unit body is located on top of the base plate, and movable components are fixedly connected to all four sides of the bottom of the base plate. The movable components include support blocks located around the bottom of the base plate, and threaded holes are opened around the top of the base plate. Rotating bolts are threaded to the inner surface of the threaded holes. By setting a rotating groove inside the support block, cooperating with the rollers and sliding plates on the connecting rod, and using the through holes and rotating bolts on the mounting block, the mounting block can drive the connecting rod in the sliding plate to move up or down, thereby determining whether the rollers are in contact with the ground. This structure facilitates movement, is simple in structure, and effectively reduces the failure rate.

[0004] While the above-mentioned solution has the advantages mentioned above, it also has disadvantages. Although it can be made easy to move and simple in structure by setting a rotating groove inside the support block, cooperating with the rollers and sliding plate on the connecting rod, and using the through hole and rotating bolt on the mounting block, the mounting block can drive the connecting rod in the sliding plate to move up or down, thus determining whether the rollers are in contact with the ground. This structure can effectively reduce the failure rate. However, during the use of the gas-filled cabinet, the internal electrical components are prone to generating a lot of heat, causing the internal temperature of the gas-filled cabinet to rise. When the sulfur hexafluoride inside the gas-filled cabinet encounters high temperatures, it is easy to produce sulfur dioxide and hydrogen fluoride, which are toxic and can easily cause harm to the human body, posing certain safety hazards. Summary of the Invention

[0005] The purpose of this invention is to address the problem in existing technologies where, although a rotating groove is provided inside the support block, along with rollers and a sliding plate on the connecting rod, and through holes and rotating bolts on the mounting block, the mounting block can move the connecting rod in the sliding plate up or down, thus determining whether the rollers contact the ground. This structure is easy to move, simple, and effectively reduces the failure rate. However, during use, the electrical components inside the gas-filled cabinet easily generate a large amount of heat, causing the internal temperature of the gas-filled cabinet to rise. When the sulfur hexafluoride inside the gas-filled cabinet encounters high temperatures, it easily produces sulfur dioxide and hydrogen fluoride, which are toxic and can easily harm the human body, posing a certain safety hazard.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a 35kV sulfur hexafluoride gas-filled switchgear with good heat dissipation, comprising: a gas-filled switchgear body and a dust removal mechanism. The dust removal mechanism is located below the gas-filled switchgear body. U-shaped tubes are fixedly embedded on opposite sides of the gas-filled switchgear body near the bottom. Connecting pipes are fixedly installed at one end of each of the two U-shaped tubes. Multiple U-shaped tubes are fixedly embedded at equal intervals on the outer surface of the two connecting pipes. A refrigeration device is fixedly installed on the side of the gas-filled switchgear body near the bottom. A pump body is fixedly installed on the side of the gas-filled switchgear body near the bottom, and a connecting pipe is fixedly installed at the pump's pumping end. Second, one end of the connecting pipe is fixedly embedded in one side of the refrigeration equipment, one end of one of the U-shaped pipes is fixedly embedded in the other side of the refrigeration equipment, and one end of the other U-shaped pipe is fixedly installed at the drain end of the pump body. A through hole is opened at the center of the bottom of the gas cabinet body. An air inlet pipe is fixedly embedded in the inner wall of the through hole. A triangular bracket is fixedly installed on the inner wall of the air inlet pipe near the top. A rotating shaft is movably embedded in the center of the triangular bracket. A fan blade is fixedly sleeved on one end of the rotating shaft. A dual-axis motor is fixedly installed at the bottom of the triangular bracket. One output shaft of the dual-axis motor is fixedly installed at one end of the rotating shaft.

[0007] Preferably, a circular dustproof plate is fixedly embedded in the inner wall of the air intake pipe near the bottom, and a rotating shaft is movably embedded in the center of the circular dustproof plate. One end of the rotating shaft is fixedly installed at the other output end of the dual-axis motor. Multiple arc-shaped dustproof plates are fixedly embedded in the outer surface of the air intake pipe near the bottom in a circumferential array. The arrangement of the arc-shaped dustproof plates and the circular dustproof plates plays a certain role in dust prevention.

[0008] Preferably, the dust removal mechanism includes a block, the top of which is fixedly installed at the other end of the rotating shaft. Slots are provided on opposite sides of the block, and inserts are movably embedded in the two slots. Square bars are fixedly installed on opposite sides of the two inserts. The block, inserts, and square bars can be rotated by rotating the rotating shaft.

[0009] Preferably, two movable parts are symmetrically arranged at the bottom of each of the two square bars. The multiple movable parts are divided into two groups. A rubber dust removal plate is fixedly installed at one end of each of the two groups of movable parts. A compression spring is movably sleeved on the outer surface of each of the multiple movable parts. Under the reset force of the compression spring, the rubber dust removal plate can be in close contact with the circular dustproof plate, which facilitates the cleaning of dust on the surface of the circular dustproof plate.

[0010] Preferably, an L-shaped plate is fixedly installed on one side of each of the two square bars, and two movable parts are provided on one side of each of the two L-shaped plates. The movable parts are divided into two groups on average, and a rubber dust removal plate is fixedly installed on one end of each of the two groups of movable parts. A compression spring is movably sleeved on the outer surface of each of the movable parts. Under the restoring force of the compression spring, the rubber dust removal plate can be made to make close contact with the outer surface of the air inlet pipe, thereby facilitating the cleaning of dust on the surface of the arc-shaped dustproof plate.

[0011] Preferably, each of the two insert blocks has a limiting hole on one side. Two pins are symmetrically and movably embedded on one side of the block. One end of each pin is movably embedded inside the two limiting holes. A connecting block is fixedly installed on the other end of each pin. A handle is fixedly installed on one side of the connecting block. Compression springs are movably sleeved on the outer surface of each pin. One end of each compression spring is symmetrically and fixedly installed on one side of the block. The other end of each compression spring is symmetrically and fixedly installed on the other side of the connecting block. By holding the handle and pulling the connecting block and pins to one side, the pins are disengaged from the limiting holes, and the compression springs are stretched simultaneously. At this time, the insert blocks can be removed from the slots, so that the second rubber dust collector plate and the first rubber dust collector plate can be replaced.

[0012] Preferably, a cleaning mechanism is provided below the dust removal mechanism. The cleaning mechanism includes a hollow cylinder, the top of which is fixedly installed at the bottom of the block. A round rod is movably embedded at the bottom of the hollow cylinder. A magnet is fixedly installed at one end of the round rod, and the outer surface of the magnet is movably embedded inside the hollow cylinder. An electromagnet is fixedly installed at the top of the inner wall of the hollow cylinder. A cleaning strip is fixedly installed at the other end of the round rod. The dust removal mechanism drives the cleaning mechanism to rotate, which allows the cleaning strip to clean the garbage under the gas tank body.

[0013] Preferably, a conical column is fixedly sleeved on the outer surface of the round rod near the magnet block. The outer surface of the conical column is movably embedded inside the hollow cylinder. A fixing column is fixedly installed on the inner wall of the hollow cylinder near the center. A conical groove is opened at the top of the fixing column. The outer surface of the round rod is movably sleeved at the center of the fixing column. By driving the conical column to insert into the conical groove of the fixing column through the round rod, friction can be generated between the conical column and the fixing column.

[0014] Preferably, an annular piece one is fixedly sleeved on the outer surface of the round rod near the fixed column. The outer surface of the annular piece one is movably embedded inside the hollow cylinder. An annular piece two is rotatably connected to the inner wall of the hollow cylinder near the bottom. The center of the annular piece two is movably sleeved on the outer surface of the round rod. An elastic element is provided on the outer surface of the round rod. One end of the elastic element is fixedly installed at the bottom of the annular piece one, and the other end of the elastic element is fixedly installed at the top of the annular piece two. Under the restoring force of the elastic element, the annular piece one can be driven to move upward, and the round rod, the conical column, and the magnet block can be driven to move upward simultaneously, so that the conical column disengages from the conical groove of the fixed column. At this time, when the hollow cylinder rotates, the round rod and the cleaning strip cannot rotate with it.

[0015] Preferably, the two U-shaped pipes, the two connecting pipes, and the multiple U-shaped pipes are connected together. One end of one of the U-shaped pipes is connected to the interior of the refrigeration equipment, and one end of the connecting pipe is connected to the interior of the refrigeration equipment. This arrangement facilitates water circulation.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. This invention controls the pump body to start via a controller, drawing water from inside the refrigeration equipment through connecting pipe two. The water then passes sequentially through another U-shaped pipe one, one connecting pipe one, multiple U-shaped pipe two, another connecting pipe one, and one U-shaped pipe one, absorbing and carrying away heat from inside the gas-filled cabinet body. This heat then enters the refrigeration equipment to cool the water. Simultaneously, the controller starts a dual-axis motor, causing one output shaft to drive a rotating shaft one, which in turn drives the fan blades to rotate, blowing gas towards the inside of the gas-filled cabinet body. This allows for rapid delivery of the cold air carried by connecting pipe one to various locations inside the gas-filled cabinet body, achieving a rapid cooling effect. This prevents the temperature inside the gas-filled cabinet body from rising, thus preventing sulfur hexafluoride from reacting with high temperatures to produce toxic gases such as sulfur dioxide and hydrogen fluoride, which could harm the human body, thereby improving the safety of the device.

[0017] 2. In this invention, the second rotating shaft is driven by the other output shaft of the dual-axis motor, which in turn drives the dust removal mechanism to rotate. This allows the second and first rubber dust removal plates to clean the dust and other impurities adhering to the surfaces of the circular and curved dustproof plates, respectively. This prevents dust and other impurities from clogging the holes in the circular and curved dustproof plates, thus affecting the amount of gas entering the air intake pipe and ensuring the heat dissipation effect of the device. Furthermore, through the cooperation of the second movable part and the second compression spring, and the first movable part and the first compression spring, the second rubber dust removal plate is always in close contact with the circular dustproof plate, and the first rubber dust removal plate is in close contact with the curved dustproof plate. This prevents the rubber strips of the first and second rubber dust removal plates from becoming worn and no longer in contact with the curved and circular dustproof plates.

[0018] 3. In this invention, the electromagnet is activated by a controller, giving it the same magnetism as the magnetic block. This allows the electromagnet and magnetic block to repel each other, causing the magnetic block to slide downwards along the round rod. Simultaneously, this causes the conical column and annular plate to move downwards, compressing the elastic element. As the conical column gradually embeds into the conical groove of the fixed column, friction occurs between them. At this point, the round rod and the hollow cylinder remain relatively fixed, and the cleaning strip moves downwards a certain distance. Furthermore, the rotation of the dust removal mechanism drives the cleaning mechanism to rotate, which in turn drives the cleaning strip to rotate, effectively cleaning the debris below the gas chamber. This facilitates cleaning the bottom of the gas chamber for workers, reducing their workload. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, such as Figure 1 - Figure 9As shown, the present invention provides a technical solution: a 35kV sulfur hexafluoride gas-filled switchgear with good heat dissipation, comprising: a gas-filled switchgear body 1 and a dust removal mechanism 3. The dust removal mechanism 3 is located below the gas-filled switchgear body 1. U-shaped tubes 102 are fixedly embedded on opposite sides of the gas-filled switchgear body 1 near the bottom. Connecting pipes 103 are fixedly installed at one end of each U-shaped tube 102. Multiple U-shaped tubes 104 are fixedly embedded at equal intervals on the outer surface of the connecting pipes 103. A refrigeration device 105 is fixedly installed on the side of the gas-filled switchgear body 1 near the bottom. A pump body 107 is fixedly installed on the side of the gas-filled switchgear body 1 near the bottom. Connecting pipes 106 are fixedly installed at the pumping end of the pump body 107. One end of the connecting pipe 106 is fixedly embedded on one side of the refrigeration device 105. One end of one of the U-shaped tubes 102 is fixedly embedded in the side of the refrigeration device 105. On the other side, one end of another U-shaped tube 102 is fixedly installed at the drain end of the pump body 107. A through hole 101 is opened at the center of the bottom of the gas cabinet body 1. An air inlet pipe 2 is fixedly embedded in the inner wall of the through hole 101. A triangular bracket 201 is fixedly installed on the inner wall of the air inlet pipe 2 near the top. A rotating shaft 202 is movably embedded in the center of the triangular bracket 201. A fan blade 203 is fixedly sleeved at one end of the rotating shaft 202. A dual-axis motor 207 is fixedly installed at the bottom of the triangular bracket 201. One of the output shafts of the dual-axis motor 207 is fixedly installed at one end of the rotating shaft 202. The two U-shaped tubes 102, the two connecting pipes 103, and the multiple U-shaped tubes 104 are connected. One end of one U-shaped tube 102 is connected to the inside of the refrigeration equipment 105, and one end of the connecting pipe 106 is connected to the inside of the refrigeration equipment 105.

[0023] In this embodiment, the pump body 107 is started by the controller, which draws the water cooled inside the refrigeration equipment 105 through the connecting pipe 106. The water then passes sequentially through another U-shaped pipe 102, one connecting pipe 103, multiple U-shaped pipes 104, another connecting pipe 103, and another U-shaped pipe 102, absorbing and carrying away the heat from inside the gas-filling cabinet body 1, which then enters the refrigeration equipment 105 to cool the water. This process is repeated. Simultaneously, the dual-axis motor 207 is started by the controller, causing one of its output shafts to drive the rotating shaft 2. The rotation of the 02 fan blades 203 synchronously drives the fan blades 203 to rotate, allowing external gas to enter the air inlet pipe 2 through the arc-shaped dustproof plate 204 and the circular dustproof plate 205. This causes the gas to blow towards the interior of the gas filling cabinet 1, quickly delivering the cold air carried by the connecting pipe 103 to various locations inside the gas filling cabinet 1. This achieves rapid cooling, preventing the temperature inside the gas filling cabinet 1 from rising and preventing sulfur hexafluoride from producing toxic gases such as sulfur dioxide and hydrogen fluoride when exposed to high temperatures, thus improving the safety of the device.

[0024] Example 2, as Figure 1 - Figure 9 As shown, a circular dustproof plate 205 is fixedly embedded in the inner wall of the air intake pipe 2 near the bottom. A rotating shaft 206 is movably embedded in the center of the circular dustproof plate 205. One end of the rotating shaft 206 is fixedly installed at the other output end of the dual-shaft motor 207. Multiple arc-shaped dustproof plates 204 are fixedly embedded in a circumferential array on the outer surface of the air intake pipe 2 near the bottom. The dust removal mechanism 3 includes a block 305. The top of the block 305 is fixedly installed at the other end of the rotating shaft 206. The opposite sides of the block 305... Each side has a slot 312, and each slot 312 has a movable insert block 306. A square strip 307 is fixedly installed on the opposite side of each of the two insert blocks 306. Two movable parts 308 are symmetrically arranged at the bottom of each of the two square strips 307. These movable parts 308 are divided into two groups, and a rubber dust removal plate 309 is fixedly installed at one end of each group of movable parts 308. A compression spring 310 is movably fitted onto the outer surface of each movable part 308. The two square strips... One side of each of the two L-shaped plates 301 is fixedly installed. Each side of the two L-shaped plates 301 is provided with two movable parts 302. The multiple movable parts 302 are divided into two groups. One end of each group of movable parts 302 is fixedly installed with a rubber dust removal plate 303. The outer surface of each of the multiple movable parts 302 is movably fitted with a compression spring 304. One side of each of the two insert blocks 306 is provided with a limiting hole 311. One side of the block 305 is symmetrically fitted with two pins 313. One end of each pin 313 is movably fitted into the two limiting holes 311. The other end of each pin 313 is fixedly installed with a connecting block 314. One side of the connecting block 314 is fixedly installed with a handle 316. The outer surface of each pin 313 is movably fitted with a compression spring 315. One end of each compression spring 315 is symmetrically fixedly installed on one side of the block 305. The other end of each compression spring 315 is symmetrically fixedly installed on the other side of the connecting block 314.

[0025] In one embodiment, movable component 302 is movably embedded in the outer surface of L-shaped plate 301. One end of compression spring 304 is fixedly installed on the outer surface of L-shaped plate 301, and the other end of compression spring 304 is fixedly installed on the other end of movable component 302. Movable component 302 is a round rod. Movable component 308 is movably embedded in the outer surface of square bar 307. One end of compression spring 310 is fixedly installed on the bottom of square bar 307, and the other end of compression spring 310 is fixedly installed on the other end of compression spring 310. Movable component 308 is a round rod. The rotating shaft 206 is driven to rotate by the other output shaft of dual-axis motor 207, which can drive the dust removal mechanism 3 to rotate. This allows rubber dust removal plate 309 and rubber dust removal plate 303 to clean the dust and other impurities adhering to the surfaces of round dustproof plate 205 and arc-shaped dustproof plate 204, respectively, preventing dust and other impurities from blocking the holes of round dustproof plate 205 and arc-shaped dustproof plate 204 and affecting the entry of dust and other impurities. The amount of gas entering the air intake pipe 2 is controlled to ensure the heat dissipation effect of the device. Through the cooperation of movable part 2 308 and compression spring 2 310, and movable part 1 302 and compression spring 1 304, the rubber dust collector plate 2 309 is always in close contact with the circular dustproof plate 205, and the rubber dust collector plate 1 303 is in close contact with the arc-shaped dustproof plate 204. This prevents the rubber strips of the rubber dust collector plate 1 303 and rubber dust collector plate 2 309 from rubbing against the arc-shaped dustproof plate 204 due to wear. When the circular dustproof plate 205 is not in contact with the rubber dustproof plate 209 and the rubber dustproof plate 1 303 need to be replaced, by holding the handle 316 and pulling the connecting block 314 and the pin 313 to one side, the pin 313 is disengaged from the inside of the limiting hole 311, and the compression spring 315 is stretched at the same time. At this time, the insert block 306 can be removed from the inside of the slot 312, so that the rubber dustproof plate 2 309 and the rubber dustproof plate 1 303 can be replaced.

[0026] In another embodiment, movable component 302 is fixedly installed on the outer surface of L-shaped plate 301 near rubber dust removal plate 303. One end of compression spring 304 is fixedly installed on the outer surface of L-shaped plate 301, and the other end of compression spring 304 is fixedly installed on the outer surface of rubber dust removal plate 303. Movable component 302 is a telescopic rod. Movable component 308 is fixedly installed on the top of square bar 307. One end of compression spring 310 is fixedly installed on the top of square bar 307, and the other end of compression spring 310 is fixedly installed on the bottom of rubber dust removal plate 309. Movable component 308 is a telescopic rod. The rotating shaft 206 is driven to rotate by the other output shaft of dual-axis motor 207, which can drive the dust removal mechanism 3 to rotate. This allows rubber dust removal plate 309 and rubber dust removal plate 303 to clean the dust and other impurities adhering to the surfaces of circular dustproof plate 205 and arc-shaped dustproof plate 204, respectively, preventing dust and other impurities from clogging the holes of circular dustproof plate 205 and arc-shaped dustproof plate 204. This design ensures effective heat dissipation by controlling the amount of gas entering the intake pipe 2. Furthermore, the interaction between movable part 308 and compression spring 310, and movable part 302 and compression spring 304, ensures that the rubber dust collector plate 309 remains in close contact with the circular dustproof plate 205, and that the rubber dust collector plate 303 remains in close contact with the arc-shaped dustproof plate 204. This prevents the rubber strips of the rubber dust collector plate 303 and the rubber dust collector plate 309 from wearing out and contacting the arc-shaped dustproof plate. When the rubber dust collector 204 and the circular dustproof plate 205 are not in contact, and it is necessary to replace the second rubber dust collector 309 and the first rubber dust collector 303, by holding the handle 316, the connecting block 314 and the pin 313 are pulled to one side, so that the pin 313 is disengaged from the inside of the limiting hole 311, and the compression spring 315 is stretched at the same time. At this time, the insert 306 can be removed from the inside of the slot 312, so that the second rubber dust collector 309 and the first rubber dust collector 303 can be replaced.

[0027] Example 3, as Figure 1 - Figure 9As shown, a cleaning mechanism 4 is provided below the dust removal mechanism 3. The cleaning mechanism 4 includes a hollow cylinder 403. The top of the hollow cylinder 403 is fixedly installed at the bottom of the block 305. A round rod 402 is movably embedded at the bottom of the hollow cylinder 403. A magnet block 405 is fixedly installed at one end of the round rod 402. The outer surface of the magnet block 405 is movably embedded inside the hollow cylinder 403. An electromagnet 404 is fixedly installed at the top of the inner wall of the hollow cylinder 403. A cleaning strip 401 is fixedly installed at the other end of the round rod 402. A conical column 406 is fixedly sleeved on the round rod 402 near the outer surface of the magnet block 405. The outer surface of the conical column 406 is movably embedded inside the hollow cylinder 403. The hollow cylinder 403 is near the center. A fixing post 407 is fixedly installed on the inner wall of the cavity. A tapered groove is opened on the top of the fixing post 407. The outer surface of the round rod 402 is movably sleeved at the center of the fixing post 407. An annular piece 408 is fixedly sleeved on the round rod 402 near the outer surface of the fixing post 407. The outer surface of the annular piece 408 is movably embedded in the interior of the hollow cylinder 403. An annular piece 410 is rotatably connected to the inner wall of the hollow cylinder 403 near the bottom. The center of the annular piece 410 is movably sleeved on the outer surface of the round rod 402. An elastic element 409 is provided on the outer surface of the round rod 402. One end of the elastic element 409 is fixedly installed at the bottom of the annular piece 408, and the other end of the elastic element 409 is fixedly installed at the top of the annular piece 410.

[0028] In one embodiment, the elastic element 409 is movably sleeved on the outer surface of the round rod 402. The elastic element 409 is a compression spring. The controller controls the electromagnet 404 to start, making it have the same magnetism as the magnet block 405. Thus, under the repulsive action of the like poles of the electromagnet 404 and the magnet block 405, the magnet block 405 drives the round rod 402 to slide downward, simultaneously driving the conical column 406 and the annular plate 408 to move downward, compressing the elastic element 409. When the conical column 406 gradually embeds into the conical groove of the fixed column 407, the conical column 406 will rub against the fixed column 407. At this time, the round rod 402 and the hollow round column 403 remain relatively fixed, and the cleaning strip 401 moves downward a certain distance. Also, because the dust removal mechanism 3 rotates, it can carry... The rotating cleaning mechanism 4 drives the cleaning strip 401 to rotate, cleaning the debris under the gas tank body 1. This makes it easier for staff to clean the debris at the bottom of the gas tank body 1, reducing their workload. When the debris at the bottom of the gas tank body 1 is cleaned, the controller controls the electromagnet 404 to turn off, causing it to lose its magnetism. At this time, the repulsive force of the electromagnet 404 on the magnet block 405 disappears. Under the reset force of the elastic element 409, the annular plate 408 can be moved upward, simultaneously moving the round rod 402, the conical column 406, and the magnet block 405 upward. This causes the conical column 406 to disengage from the conical groove of the fixed column 407. At this time, when the hollow cylinder 403 rotates, the round rod 402 and the cleaning strip 401 cannot rotate with it.

[0029] In another embodiment, the elastic element 409 is movably sleeved on the outer surface of the round rod 402. The elastic element 409 is a spring sheet. The controller controls the electromagnet 404 to start, making it have the same magnetism as the magnet block 405. Thus, under the repulsive action of the like poles of the electromagnet 404 and the magnet block 405, the magnet block 405 drives the round rod 402 to slide downward, simultaneously driving the conical column 406 and the annular plate 408 to move downward, compressing the elastic element 409. When the conical column 406 gradually embeds into the conical groove of the fixed column 407, the conical column 406 will rub against the fixed column 407. At this time, the round rod 402 and the hollow round column 403 remain relatively fixed, and the cleaning strip 401 moves downward a certain distance. Also, because the dust removal mechanism 3 rotates, it can... The cleaning mechanism 4 rotates, which in turn drives the cleaning strip 401 to rotate, cleaning the debris under the gas tank body 1. This makes it easier for staff to clean the debris at the bottom of the gas tank body 1, reducing their workload. When the debris at the bottom of the gas tank body 1 is cleaned, the controller controls the electromagnet 404 to close, causing it to lose its magnetism. At this time, the repulsive force of the electromagnet 404 on the magnet block 405 disappears. Under the reset force of the elastic element 409, the annular plate 408 can be moved upward, simultaneously driving the round rod 402, the conical column 406, and the magnet block 405 to move upward, causing the conical column 406 to disengage from the conical groove of the fixed column 407. At this time, when the hollow cylinder 403 rotates, the round rod 402 and the cleaning strip 401 cannot rotate with it.

[0030] Working principle: During use, when the electrical components inside the gas chamber 1 generate a large amount of heat, the controller starts the pump 107, which draws water from the cooling device 105 through the connecting pipe 106. The water then passes through another U-shaped pipe 102, one connecting pipe 103, multiple U-shaped pipes 104, another connecting pipe 103, and another U-shaped pipe 102, absorbing and carrying away the heat from inside the gas chamber 1. This heat then enters the cooling device 105 to cool the water. This process is repeated. Simultaneously, the controller starts the dual-shaft motor 207, causing one output shaft to drive the rotating shaft 202 to rotate, which in turn drives the fan blades 203, thus allowing external gas to pass through the arc-shaped... At the positions of dustproof plates 204 and circular dustproof plates 205, the air enters the interior of the air inlet pipe 2, causing the gas to blow towards the interior of the gas filling cabinet body 1. This allows for rapid delivery of the cold air carried by the connecting pipe 103 to various locations inside the gas filling cabinet body 1, achieving a rapid cooling effect. This prevents the temperature inside the gas filling cabinet body 1 from rising, thus preventing sulfur hexafluoride from reacting with high temperatures to produce toxic gases such as sulfur dioxide and hydrogen fluoride, which could harm the human body and improve the safety of the device. Simultaneously, the other output shaft of the dual-shaft motor 207 drives the rotating shaft 206 to rotate, which in turn drives the dust removal mechanism 3 to rotate. This allows the rubber dust removal plates 309 and 303 to respectively remove the dust adhering to the surfaces of the circular dustproof plate 205 and the arc-shaped dustproof plate 204. Dust and other impurities are cleaned to prevent them from blocking the holes in the circular dustproof plate 205 and the arc-shaped dustproof plate 204, thus affecting the amount of gas entering the air intake pipe 2 and ensuring the heat dissipation effect of the device. Through the cooperation of the movable part 2 308 and the compression spring 2 310, and the movable part 1 302 and the compression spring 1 304, the rubber dust removal plate 2 309 is kept in close contact with the circular dustproof plate 205, and the rubber dust removal plate 1 303 is kept in close contact with the arc-shaped dustproof plate 204. This prevents the rubber strips of the rubber dust removal plates 1 303 and 2 309 from becoming worn and no longer in contact with the arc-shaped dustproof plate 204 and the circular dustproof plate 205. When it is necessary to clean the rubber dust removal plates 2 309 and 1 303... During replacement, by holding handle 316, pull connecting block 314 and pin 313 to one side, causing pin 313 to disengage from the limiting hole 311. Simultaneously, compression spring 315 is stretched, allowing insert block 306 to be removed from slot 312. This allows replacement of rubber dust collector plate 2 309 and rubber dust collector plate 1 303. When this device is used in one place for an extended period, and there is garbage under the gas chamber body 1, the controller activates electromagnet 404, giving it the same magnetism as magnet block 405. This allows the like poles of electromagnet 404 and magnet block 405 to repel each other. Since the repulsive force between electromagnet 404 and magnet block 405 is greater than the elastic force of elastic element 409,The magnet 405 causes the round rod 402 to slide downwards, simultaneously moving the conical column 406 and the annular plate 408 downwards, compressing the elastic element 409. As the conical column 406 gradually embeds into the conical groove of the fixed column 407, it rubs against the fixed column 407. At this time, the round rod 402 and the hollow column 403 remain relatively fixed, and the cleaning strip 401 moves downwards a certain distance. Since the dust removal mechanism 3 rotates, it can drive the cleaning mechanism 4 to rotate, thereby driving the cleaning strip 401 to rotate, cleaning the debris below the gas chamber body 1. This facilitates the cleaning of debris at the bottom of the gas chamber body 1 by the staff. The cleaning process reduces the workload of staff. When the debris at the bottom of the gas chamber 1 is cleaned, the controller shuts off the electromagnet 404, causing it to lose its magnetism. At this point, the repulsive force of the electromagnet 404 on the magnet 405 disappears, and the electromagnet 404 does not attract the magnet 405 when it is not energized. Under the reset force of the elastic element 409, the annular plate 408 moves upward, simultaneously moving the round rod 402, the conical column 406, and the magnet 405 upward. This causes the conical column 406 to disengage from the conical groove of the fixed column 407. At this time, when the hollow cylinder 403 rotates, the round rod 402 and the cleaning strip 401 cannot rotate with it.
