[0002] Power electrical cabinets are key equipment in power systems, used to control, monitor, and manage electricity. They are categorized by voltage into high-voltage and low-voltage types, and by function into incoming and outgoing cabinets. Cabinets are often made of steel plates and contain busbars and various electrical components. Circuits are controlled by circuit breakers, safety is ensured by protective devices, and parameters are monitored with the help of measuring instruments. They are widely used in industry, construction, and power systems, and are of great significance to stable power supply and energy distribution. Traditional power electrical cabinets mainly rely on fixed heat dissipation holes for natural heat dissipation. The heat dissipation capacity is fixed and limited, so the heat dissipation efficiency is low. When the temperature inside the electrical cabinet is too high, it cannot be cooled down in time. In addition, the dust screen of traditional electrical cabinets is mostly cleaned manually, otherwise it will be blocked and affect heat dissipation, and manual cleaning is more troublesome. Summary of the Invention

[0006] The present invention is further configured as follows: the heat dissipation assembly includes a connecting frame, two groups of the connecting frames are respectively welded to both sides of the electrical cabinet body, and one group of the connecting frames is internally bolted to a dual-axis motor.

[0007] Using the above technical solution, the dual-axis motor is installed on the surface of the connecting frame, and the model of the dual-axis motor is Huahao IPMOT002, which can use the side to dissipate heat.

[0008] The present invention is further configured as follows: the output end of the dual-axis motor is fixedly connected to a rotating rod through a coupling, and the other end of the rotating rod is rotatably connected to another set of connecting frames, both ends of the rotating rod are welded with reverse spiral fans, one end of the rotating rod is welded with two sets of first rotors, and both ends of the rotating rod are welded with two sets of push rods.

The anti-spiral fan can prevent external dust from entering the interior of the electrical cabinet while discharging the heat inside the electrical cabinet to the outside.

[0010] The present invention is further configured as follows: spiral fans are provided inside the electrical cabinet body and at the top and bottom of the dual-axis motor, a bearing is fixedly sleeved on the surface of the spiral fan, and the bearing is fixedly connected to the electrical cabinet body, and a second rotor is welded on the surface of the spiral fan.

[0011] With the above technical solution, the rotating rod will use the first rotating wheel and the belt to drive the second rotating wheel and the reverse spiral fan to rotate, and the reverse spiral fan will blow out the heat inside the electrical cabinet.

[0012] The present invention is further configured as follows: a belt is commonly connected between the second rotating wheel and the first rotating wheel, connecting plates are symmetrically welded to the inner walls on both sides of the electrical cabinet body, and two sets of dampers are bolted to one side of the connecting plate.

[0013] By adopting the above technical solution, when the damper is compressed, it will drive the mounting plate and the heat sink to recover slowly.

[0017] Using the above technical solution, when the dual-axis motor is running, it will drive the small gear to rotate, thereby driving the large gear to rotate inside the second support plate using the rotating column, and due to the use of the transmission belt, the two sets of third wheels in the middle will drive the third wheels at both ends to rotate, and during the operation of the transmission belt, it will drive the push column to move synchronously. Due to the transmission ratio design of the large gear and the small gear, when the small gear rotates one circle, the large gear will only rotate part of the way.

[0018] The present invention is further configured as follows: connecting shells are welded at both ends of both sides of the electrical cabinet body, a sliding shell is slidably connected to the inside of the connecting shell, two groups of second telescopic springs are connected to one side of the inner wall of the sliding shell through a spring fixing piece, and the other ends of the two groups of second telescopic springs are commonly connected to the second oblique block through a spring fixing piece, a push plate is welded on one side of the sliding shell, and the push plate and the push column are slidably arranged, a second spring push rod is bolted between one side of the inner wall of the upper two groups of the connecting shell and the sliding shell, and a spring pull rod is bolted between one side of the inner wall of the lower two groups of the connecting shell and the sliding shell.

[0019] With the above technical solution, when the push rod rotates, it pushes the two sets of heat sinks to both sides. When it is pushed to the appropriate position, the hanging rod will squeeze the inclined surface of the second oblique block. Since the second oblique block is made of tempered glass and has a relatively smooth surface, the second oblique block will be squeezed into the sliding shell. When the hanging rod passes over the second oblique block, the second telescopic spring will pop out the second oblique block, so that the hanging rod will hang on the surface of the second oblique block, which can prevent the heat sink from resetting. After the electrical cabinet body has been dissipating heat for a period of time, the transmission belt will drive the push column to push the push plate, so that the push plate drives the sliding shell and the second oblique block to slide, so that the second oblique block can be separated from the contact with the hanging rod, so that the damper and the first telescopic spring will drive the heat sink to reset and close.

[0020] The present invention is further configured as follows: the dust-proof and dust-removing assembly includes a first spring push rod, several groups of the first spring push rods are respectively bolted to the two ends of one side of the heat dissipation plate, several groups of the first spring push rod piston ends are commonly bolted to a dust-proof plate, one end of the dust-proof plate is welded with a hanging rod, and the hanging rod is detachably connected to the second oblique block.

[0021] With the above technical solution, the dustproof plate is used to protect the heat sink from dust, thereby preventing dust from entering the interior of the electrical cabinet. The dustproof plate can be moved by the first spring push rod.

[0022] The present invention is further configured as follows: a plurality of first oblique blocks are welded to both ends of one side of the dustproof plate, four groups of baffles are welded to both sides of the electrical cabinet body, and the baffles are detachably connected to the first oblique blocks.

[0023] With the above technical solution, both sides of the first inclined block are inclined, and the surface is relatively smooth due to the tempered glass material, so when the barrier rod squeezes the first inclined block, the first inclined block will move to one side.

[0024] In summary, the present invention has the following beneficial effects: When in use, the heat dissipation component is started, and the heat dissipation component will drive the heat dissipation structures on both sides of the electrical cabinet body to open. Opening both sides will help air circulation, and then the heat dissipation component will drive one of the internal heat dissipation mechanisms to dissipate heat, and at the same time as the heat dissipation component is opened, it will drive the dust removal component to move. Since the dust removal component has been used for a long time, it will affect the heat dissipation effect if it is not cleaned. Therefore, during the opening process, the dust on the surface of the dust proof structure will be automatically cleaned. In order to prevent the dust from entering the interior of the electrical cabinet body during cleaning, the heat dissipation component will drive another set of heat dissipation mechanisms to discharge the heat inside the electrical cabinet body while blowing air to the outside, thereby preventing external dust from entering the interior of the electrical cabinet body, thereby achieving the effect of facilitating heat dissipation and dust removal inside the electrical cabinet body.

A second rotor 506 is welded on the surface of the spiral fan 507; a belt 505 is commonly connected to the second rotor 506 and the first rotor 504. Connecting plates 510 are symmetrically welded to the inner walls of both sides of the electrical cabinet body 1, and two groups of dampers 511 are bolted to one side of the connecting plate 510; a first telescopic spring 512 is sleeved on the surface of the damper 511, and one end of the first telescopic spring 512 and the damper 511 are commonly fixedly connected to a mounting plate 513, and the two ends of the first telescopic spring 512 are respectively connected between the connecting plate 510 and the mounting plate 513 through spring fixing members, and one side of the mounting plate 513 A heat sink 514 is welded thereto; a pinion 517 is fixedly connected to the other output end of the dual-axis motor 501 and one end of the rotating rod 509; a second support plate 522 is welded to the middle of both sides of the electrical cabinet body 1; a first support plate 516 is welded to both ends of both sides of the electrical cabinet body 1; a rotating column 521 is internally connected to one end of the first support plate 516 and the second support plate 522; four groups of third rotating wheels 520 are fixedly connected to the surface of the three groups of rotating columns 521; a large gear 519 is welded to the surface of the middle group of rotating columns 521, and the large gear 519 and the small gear 517 are meshed and connected; the gear ratio of the large gear 519 to the small gear 517 is 5:1; and the surfaces of the corresponding two groups of third rotating wheels 520 are commonly connected with a transmission belt 518 , one side of the two groups of transmission belts 518 are fixedly connected to a push column 523; connecting shells 524 are welded at both ends of both sides of the electrical cabinet body 1, and a sliding shell 526 is slidably connected inside the connecting shell 524. One side of the inner wall of the sliding shell 526 is connected to two groups of second telescopic springs 527 through a spring fixing member, and the other ends of the two groups of second telescopic springs 527 are commonly connected to a second oblique block 528 through a spring fixing member. A push plate 529 is welded on one side of the sliding shell 526, and the push plate 529 and the push column 523 are slidably arranged. A second spring push rod 530 is bolted between one side of the inner wall of the two groups of connecting shells 524 at the upper end and the sliding shell 526, and a spring pull rod 525 is bolted between one side of the inner wall of the two groups of connecting shells 524 at the lower end and the sliding shell 526.

[0031] Brief description of the usage process: When the dual-axis motor 501 is running, it will drive the rotating rod 509 to rotate, and the rotating rod 509 will drive the push rods 515 on both sides to rotate. While the push rods 515 are rotating, they will push the mounting plate 513, so that the upper mounting plate 513 moves upward and the lower mounting plate 513 moves downward, so that the mounting plate 513 drives the heat sink 514 and the damper 511 and the first telescopic spring 512 to move, thereby opening the heat sink 514, and while the rotating rod 509 is rotating, it will drive the first rotating wheel 504 to rotate, and the first rotating wheel 504 will use the belt 505 to drive the spiral fan 507 to rotate inside the electrical cabinet 1, and the limit plate 508 is used to limit the spiral fan 507 , since the heat sinks 514 on both sides of the electrical cabinet body 1 are open, the spiral fan 507 will blow the internal heat out from the position of the other heat sink 514, and the reverse spiral fan 503 will also rotate with the rotation of the rotating rod 509. The reverse spiral fan 503 can exhaust air outward, so it can prevent the dust on the surface of the dust-proof and dust-removing component 4 from entering the interior of the electrical cabinet body 1 when the heat sink 514 is opened. The design of the reverse spiral fan 503 can discharge the heat inside the electrical cabinet body 1 outward, and when the dual-axis motor 501 is running, it will drive the small gear 517 to rotate, thereby driving the large gear 519 to rotate inside the second support plate 522 using the rotating column 521, and due to the use of the transmission belt 518, the middle The two sets of third rotating wheels 520 drive the third rotating wheels 520 at both ends to rotate, and the transmission belt 518 will drive the push column 523 to move synchronously during operation. Due to the transmission ratio design of the large gear 519 and the small gear 517, when the small gear 517 rotates one circle, the large gear 519 will only rotate one-fifth of a circle. Because the push rod 515 pushes the two sets of heat dissipation plates 514 to both sides when rotating, the hanging rod 405 will squeeze the inclined surface of the second inclined block 528. Since the second inclined block 528 is made of tempered glass and has a relatively smooth surface, the second inclined block 528 will be squeezed into the sliding shell 526. When the hanging rod 405 passes over the second inclined block 528, the second telescopic spring 527 will pop out the second inclined block 528, thereby The hanging rod 405 is hung on the surface of the second inclined block 528, which can prevent the heat sink 514 from resetting. Since the rotation of the large gear 519 will drive the third rotating wheel 520 to rotate, the third rotating wheel 520 will drive the transmission belt 518 to rotate. When the transmission belt 518 transmits one circle, the transmission belt 518 will drive the push column 523 to contact the push plate 529, thereby squeezing the push plate 529, so that the push plate 529 drives the sliding shell 526 and the second inclined block 528 to slide, which can make the second inclined block 528 disengage from the contact with the hanging rod 405, so that the damper 511 and the first telescopic spring 512 will drive the heat sink 514 to reset and close, thereby achieving the effect of facilitating heat dissipation inside the electrical cabinet body 1 and preventing external dust from entering the electrical cabinet body 1.

[0032] Example 3: Based on Example 2, Figure 2 、 Figure 5 The dust-proof and dust-removing assembly 4 includes a first spring top rod 402, and several groups of the first spring top rods 402 are respectively bolted to the two ends of one side of the heat dissipation plate 514, and several groups of the first spring top rods 402 piston ends are commonly bolted to the dust-proof plate 401, and a hanging rod 405 is welded to one end of the dust-proof plate 401, and the hanging rod 405 is detachably connected to the second oblique block 528; several groups of first oblique blocks 404 are welded to both ends of one side of the dust-proof plate 401, and four groups of baffle rods 403 are welded to both sides of the electrical cabinet body 1, and the baffle rods 403 are detachably connected to the first oblique block 404.

[0033] Brief description of the usage process: When the heat dissipation plate 514 is opened, it will drive the dustproof plate 401 to move synchronously. When the dustproof plate 401 moves, the first inclined block 404 and the baffle 403 will squeeze each other. Since the first inclined block 404 has inclined surfaces on both sides and is made of tempered glass with a relatively smooth surface, the first inclined block 404 will move and drive the dustproof plate 401 to move using the first spring push rod 402. When the baffle 403 passes over the first inclined block 404, the first spring push rod 402 will suddenly drive the dustproof plate 401 to reset, and the dustproof plate 401 will form a slight knock with the baffle 403, which can make the dust on the surface of the dustproof plate 401 fall off, prevent the dustproof holes from being blocked and affect heat dissipation, thereby achieving the effect of facilitating dust prevention and dust removal of the electrical cabinet body 1.
