[0009] According to the above technical solution, the circulation component includes a third baffle ring fixedly installed on the outer wall of the sleeve plate, a second slide rod is fixedly installed on the outer wall of the third baffle ring, a second sealing ring is fixedly installed on the end of the second slide rod away from the third baffle ring, a delivery pipe is slidably arranged on the outer wall of the second sealing ring, a fourth baffle ring is fixedly installed on the inner wall of the delivery pipe, an end of the delivery pipe away from the fourth baffle ring is connected to a blowing plate, a heat dissipation port is opened on the outer wall of the power distribution cabinet, and a dust baffle is fixedly installed on the outer wall of the heat dissipation port.

[0010] According to the above technical solution, the end of the fixed plate away from the power distribution cabinet is arranged at an inclined surface, and the end of the brush plate is arranged at an inclined surface. Under the restriction of the spring, when the brush plate contacts and squeezes the fixed plate, the brush plate can produce a vibration effect, and at the same time, the brush plate can drive the first sliding rod and the first sealing ring to slide into the inside of the slide groove, push the gas inside the slide groove, and spray it out from the blowing frame to blow and clean the dust in the gaps of the electronic components.

[0011] According to the above technical solution, there are two air blowing frames, which are symmetrically distributed about the center line of the sleeve plate. With the cooperation of the two air blowing frames, the dust cleaning effect on electronic components can be improved.

[0012] According to the above technical solution, there are two baffles, which are symmetrically distributed about the center line of the distribution cabinet. The baffles are arranged in an inclined surface, and a dust outlet is provided at the bottom of the distribution cabinet. Under the restriction of the baffles, the rotation of the opening and closing plate can be restricted. At the same time, the baffles arranged in an inclined surface can guide the dust and transport the dust to the top surface of the opening and closing plate. The baffles are fixedly installed to the inner wall of the dust outlet.

[0013] According to the above technical solution, the outer wall of the second sealing ring slides in a sealed manner with the inner wall of the delivery pipe, and the blowing plate is connected to the inside of the distribution cabinet. Under its restriction, when the second sealing ring slides into the delivery pipe, it can push the gas inside the delivery pipe and blow it into the distribution cabinet through the blowing plate, so that the air inside the distribution cabinet can circulate.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The leakage-proof, fire-proof and explosion-proof distribution cabinet of the present invention is composed of a cleaning component as one of its components. When it is necessary to clean the dust inside the distribution cabinet, the motor is started at this time, and the reciprocating screw fixedly installed at its output end begins to rotate. Since the second sliding rod fixedly installed inside the sleeve plate is slidably arranged with the conveying pipe connected to the top surface of the distribution cabinet, under its restriction, the rotating reciprocating screw can drive the sleeve plate to move up and down, and the first sliding rod slidingly arranged inside the sleeve plate drives the brush plate to move accordingly, so that the brush plate cleans the dust attached to the surface of the electronic components inside the distribution cabinet. Since the brush fixedly installed on the outer wall of the brush plate is made of flexible material, it will not damage the electronic components, and the brush fits the surface of the electronic components to clean the dust in the gaps of the electronic components, so that the electronic components can run more smoothly. When the sleeve plate drives the brush plate to move up and down The end of the brush plate contacts and squeezes the outer wall of the fixed plate fixedly installed on the inner wall of the distribution cabinet. Since the end of the brush plate is arranged at an inclined surface and the end of the fixed plate is arranged at an inclined surface, under its restriction, when the brush plate is squeezed by the fixed plate, the brush plate drives the first slide bar and the first sealing ring to slide inside the slide groove, and compresses the spring sleeved on the outer wall of the first slide bar. When the brush plate is no longer squeezed by the fixed plate, under the elastic action of the spring, it pushes the brush plate away from the sleeve plate. Under the restriction of the first retaining ring, the first slide bar is prevented from sliding out of the slide groove, and the reciprocating polarization effect is produced on the brush plate to prevent dust from being stuck inside the brush plate. This structure can clean the dust on the surface of electronic components and make the brush plate vibrate at the same time to prevent dust from adhering to the inside of the brush plate. The motor is a YBX5 series high-efficiency flameproof three-phase asynchronous motor.

[0015] 2. The leakage-proof, fire-proof and explosion-proof distribution cabinet of the present invention is composed of a cleaning component as one of its components. When the brush plate cleans the surface of the electronic component, the brush plate will produce a vibration effect due to the fixed plate, and the brush plate drives the first slide bar and the first sealing ring to slide inside the slide groove. Since the outer wall of the first sealing ring and the slide groove are sealed and slidingly arranged, under its restriction, the first sealing ring sliding into the slide groove compresses the gas inside the slide groove, and the connecting piece connected to the end of the slide groove conveys gas to the inside of the M-shaped tube, and the M-shaped tube conveys gas to the inside of the blowing frame, which is sprayed out by the blowing frame. The blowing frame cooperates with the brush plate to clean the dust attached to the surface of the electronic component, and also cleans the dust in the gaps of the electronic component. Under the support of the L-shaped block, the blowing frame can be stably installed on the outer wall of the sleeve plate.

[0016] 3. The leakage-proof, fire-proof and explosion-proof distribution cabinet of the present invention is composed of a dust removal assembly as one of its components. After the brush plate and the air blowing frame clean the dust inside the distribution cabinet, the dust falls downward under the action of gravity and falls on the top surface of the opening and closing plate. When the reciprocating screw drives the sleeve plate to move downward, the extrusion plate fixedly installed at the bottom of the sleeve plate moves downward accordingly, and the outer wall of the extrusion plate contacts and squeezes the top surface of the opening and closing plate, pushing the opening and closing plate so that the connecting column fixedly installed on the outer wall of the opening and closing plate rotates at the bottom of the distribution cabinet, and the opening and closing plate squeezes the elastic sheet arranged at its bottom. The opening and closing plate deflects with the hinged part with the bottom of the distribution cabinet as the rotation center to clean the dust on the top surface of the opening and closing plate from the inside of the distribution cabinet. When the sleeve plate drives the extrusion plate to move upward, it no longer contacts and squeezes the top surface of the opening and closing plate. Since one end of the elastic sheet is fixed to the bottom of the opening and closing plate, and the other end is fixed to the bottom surface of the distribution cabinet through a fixing block and a screw, under its restriction, the opening and closing plate that is not squeezed makes the elastic sheet also not squeezed. The elastic sheet pushes the opening and closing plate, and under the restriction of the baffle bar, the opening and closing plate and the bottom of the distribution cabinet can be kept level. Since the baffle bar is set on an inclined surface, under its restriction, the dust can be guided and transported to the top surface of the opening and closing plate. This structure can discharge the dust cleaned by the brush plate and the blowing frame from the inside of the distribution cabinet, and there is no need for operators to perform dust cleaning work regularly.

[0017] 4. The leakage-proof, fire-proof and explosion-proof distribution cabinet of the present invention is composed of a circulation component as one of its components. When the distribution cabinet is in use, heat dissipation treatment can be performed by cleaning the electronic components. In order to dissipate the heat of the electronic components and improve their running smoothness, it is necessary to circulate the air inside the distribution cabinet. When the sleeve moves upward, the second sliding rod fixedly installed on the outer wall of the sleeve drives the second sealing ring to slide into the inside of the conveying pipe. Since the outer wall of the second sealing ring and the inner wall of the conveying pipe slide in a sealed manner, under its restriction, the second sealing ring squeezes the gas inside the conveying pipe, and the air is sprayed into the distribution cabinet by the blowing disk connected to the end of the conveying pipe, so as to circulate the air inside the distribution cabinet. The air inside the distribution cabinet is discharged through the heat dissipation port. Under the cover of the dust baffle, dust can be prevented from entering the interior of the distribution cabinet. When the sleeve moves downward, the second sealing ring draws air into the conveying pipe, and can also increase the circulation effect of the air inside the distribution cabinet to dissipate the heat of the electronic components. This structure can make the air circulate inside the distribution cabinet, so as to improve the heat dissipation effect of the electronic components and ensure that the electronic components run smoothly.

[0021] In this embodiment, when it is necessary to clean the dust inside the distribution cabinet 1, the motor 412 is started, and the reciprocating screw 413 fixedly installed at its output end begins to rotate. Since the second sliding rod 442 fixedly installed inside the sleeve plate 414 is slidably arranged with the conveying pipe 444 connected to the top surface of the distribution cabinet 1, under its restriction, the rotating reciprocating screw 413 can drive the sleeve plate 414 to move up and down, and the first sliding rod 418 slidingly arranged inside the sleeve plate 414 drives the brush plate 420 to move accordingly, so that the brush plate 420 cleans the dust attached to the surface of the electronic components 8 inside the distribution cabinet 1. Since the brush fixedly installed on the outer wall of the brush plate 420 is made of flexible material, it will not damage the electronic components 8, and the brush The brush plate 420 fits the surface of the electronic component 8 and cleans the dust in the gap of the electronic component 8, making the electronic component 8 run more smoothly. When the sleeve plate 414 drives the brush plate 420 to move up and down, the end of the brush plate 420 contacts and squeezes the outer wall of the fixed plate 426 fixedly installed on the inner wall of the distribution cabinet 1. Since the end of the brush plate 420 is arranged in an inclined surface, and the end of the fixed plate 426 is arranged in an inclined surface, under their restriction, when the brush plate 420 is squeezed by the fixed plate 426, the brush plate 420 drives the first slide bar 418 and the first sealing ring 417 to slide into the inside of the slide groove 415, and compresses the spring 419 sleeved on the outer wall of the first slide bar 418. When the brush plate 420 is no longer squeezed by the fixed plate 426, Under the elastic action of spring 419, it pushes the brush plate 420 away from the sleeve plate 414. Under the restriction of the first retaining ring 416, the first slide bar 418 is prevented from sliding out of the slide groove 415. The reciprocating motion causes the brush plate 420 to produce a polarization effect to prevent dust from being stuck inside the brush plate 420. This structure can clean the dust on the surface of the electronic component 8 and at the same time make the brush plate 420 vibrate to prevent dust from adhering to the inside of the brush plate 420. The motor 412 is a YBX5 series high-efficiency flameproof three-phase asynchronous motor.

A sealing ring 417 slides inside the slide groove 415. Since the outer wall of the first sealing ring 417 and the slide groove 415 are sealed and slidably arranged, under its restriction, the first sealing ring 417 sliding into the slide groove 415 compresses the gas inside the slide groove 415, and the connecting piece 421 connected to the end of the slide groove 415 transports gas to the inside of the M-shaped tube 422. The M-shaped tube 422 transports gas to the inside of the blowing frame 424, and the gas is sprayed out by the blowing frame 424. The blowing frame 424 cooperates with the brush plate 420 to clean the dust attached to the surface of the electronic component 8, and also cleans the dust in the gap of the electronic component 8. With the support of the L-shaped block 423, the blowing frame 424 can be stably installed on the outer wall of the sleeve plate 414. Example 2

[0022] The preferred embodiment of the leakage-proof, fire-proof and explosion-proof distribution cabinet provided by the present invention is as follows: Figures 1 to 9As shown: the dust removal assembly 43 includes an extrusion plate 431 fixedly installed at the bottom of the sleeve plate 414, an opening and closing plate 432 is hingedly connected to the bottom of the distribution cabinet 1, a connecting column 433 is fixedly installed on the side wall of the opening and closing plate 432, a fixed block 434 is arranged at the bottom of the opening and closing plate 432, an elastic sheet 435 is fixedly installed on the outer wall of the fixed block 434, a screw 436 is sleeved inside the fixed block 434, and a baffle 437 is fixedly installed on the inner side of the bottom of the distribution cabinet 1.

[0023] In this embodiment, after the brush plate 420 and the blowing frame 424 clean the dust inside the distribution cabinet 1, the dust falls downward under the action of gravity and falls on the top surface of the opening and closing plate 432. When the reciprocating screw rod 413 drives the sleeve plate 414 to move downward, the extrusion plate 431 fixedly installed at the bottom of the sleeve plate 414 moves downward accordingly. The outer wall of the extrusion plate 431 contacts and squeezes the top surface of the opening and closing plate 432, pushing the opening and closing plate 432 so that the connecting column 433 fixedly installed on the outer wall of the opening and closing plate 432 rotates at the bottom of the distribution cabinet 1. The opening and closing plate 432 squeezes the elastic sheet 435 provided at its bottom. The opening and closing plate 432 deflects with the hinged part at the bottom of the distribution cabinet 1 as the rotation center to clean the dust on the top surface of the opening and closing plate 432 from the inside of the distribution cabinet 1. When the sleeve plate 414 drives the extrusion plate When the plate 431 moves upward, it no longer contacts and squeezes the top surface of the opening and closing plate 432. Since one end of the elastic sheet 435 is fixed to the bottom of the opening and closing plate 432, and the other end is fixed to the bottom surface of the distribution cabinet 1 through the fixing block 434 and the screw 436, under its restriction, the opening and closing plate 432 that is not squeezed makes the elastic sheet 435 also not squeezed. The elastic sheet 435 pushes the opening and closing plate 432, and under the restriction of the baffle 437, the opening and closing plate 432 can be kept level with the bottom of the distribution cabinet 1. Since the baffle 437 is set on an inclined surface, under its restriction, the dust can be guided and transported to the top surface of the opening and closing plate 432. This structure can discharge the dust cleaned by the brush plate 420 and the blowing frame 424 from the inside of the distribution cabinet 1, and there is no need for the operator to perform regular cleaning work. Example 3

[0024] The preferred embodiment of the leakage-proof, fire-proof and explosion-proof distribution cabinet provided by the present invention is as follows: Figures 1 to 9 As shown: the circulation component 44 includes a third baffle ring 441 fixedly mounted on the outer wall of the sleeve plate 414, a second slide bar 442 is fixedly mounted on the outer wall of the third baffle ring 441, a second sealing ring 443 is fixedly mounted on the end of the second slide bar 442 away from the third baffle ring 441, a delivery pipe 444 is slidably arranged on the outer wall of the second sealing ring 443, a fourth baffle ring 445 is fixedly mounted on the inner wall of the delivery pipe 444, an end of the delivery pipe 444 away from the fourth baffle ring 445 is connected to a blowing plate 446, a heat dissipation port 447 is opened on the outer wall of the distribution cabinet 1, and a dust baffle 448 is fixedly mounted on the outer wall of the heat dissipation port 447.

[0025] In this embodiment, when the power distribution cabinet 1 is used, the electronic components 8 can be cleaned to perform heat dissipation treatment. In order to dissipate the heat of the electronic components 8 and improve the smoothness of its operation, it is necessary to circulate the air inside the power distribution cabinet 1. When the sleeve 414 moves upward, the second slide bar 442 fixedly installed on the outer wall of the sleeve 414 drives the second sealing ring 443 to slide into the inside of the delivery pipe 444. Since the outer wall of the second sealing ring 443 slides with the inner wall of the delivery pipe 444 in a sealed manner, under its restriction, the second sealing ring 443 squeezes the gas inside the delivery pipe 444, and the gas at the end of the delivery pipe 444 is discharged. The air blowing disk 446 connected to the part sprays air into the distribution cabinet 1 to circulate the air inside the distribution cabinet 1. The air inside the distribution cabinet 1 is discharged through the heat dissipation port 447. Under the cover of the dust baffle 448, dust can be prevented from entering the distribution cabinet 1. When the sleeve plate 414 moves downward, the second sealing ring 443 draws air from the inside of the delivery pipe 444, and can also increase the circulation effect of the air inside the distribution cabinet 1 to dissipate heat for the electronic components 8. This structure can allow the air to circulate inside the distribution cabinet 1 to improve the heat dissipation effect of the electronic components 8 and ensure that the electronic components 8 run smoothly.

[0026] Among them, the end of the fixed plate 426 away from the distribution cabinet 1 is set at an inclined surface, and the end of the brush plate 420 is set at an inclined surface. Under the restriction of the spring 419, when the brush plate 420 and the fixed plate 426 are in contact and squeezed, the brush plate 420 can produce a vibration effect, and at the same time, the brush plate 420 can drive the first sliding rod 418 and the first sealing ring 417 to slide into the slide groove 415, pushing the gas inside the slide groove 415, which is sprayed out by the blowing frame 424 to blow and clean the dust in the gaps of the electronic components 8.

[0027] There are two air blowing frames 424 , which are symmetrically distributed about the center line of the sleeve plate 414 . With the cooperation of the two air blowing frames 424 , the dust cleaning effect on the electronic components 8 can be improved.

[0028] Among them, there are two baffles 437, which are symmetrically distributed about the center line of the distribution cabinet 1. The baffles 437 are arranged in an inclined surface, and a dust outlet is provided at the bottom of the distribution cabinet 1. Under the restriction of the baffle 437, the rotation of the opening and closing plate 432 can be restricted. At the same time, the baffle 437 arranged in an inclined surface can guide the dust and transport the dust to the top surface of the opening and closing plate 432. The baffle 437 is fixedly installed to the inner wall of the dust outlet.

[0029] Among them, the outer wall of the second sealing ring 443 slides in a sealed manner with the inner wall of the delivery pipe 444, and the blowing plate 446 is connected to the inside of the distribution cabinet 1. Under its restriction, when the second sealing ring 443 slides into the delivery pipe 444, the gas inside the delivery pipe 444 can be pushed and blown into the inside of the distribution cabinet 1 through the blowing plate 446, so that the air inside the distribution cabinet 1 can circulate.
