Description
Technical Field
[0001] This invention relates to the field of power cabinet technology, specifically to a power cabinet with dustproof function. Background Technology
[0002] A power distribution cabinet is a metal or non-metal enclosure in a power system used for the centralized installation of electrical equipment, distribution of electrical energy, control of circuits, and protection of electrical equipment. It is a core component of power networks in industries, buildings, and infrastructure, ensuring the safe, stable, and efficient transmission and distribution of electrical energy.
[0003] Patent CN111509570B discloses a dustproof power cabinet, including a power cabinet, a power display, a cabinet door, a heat dissipation mechanism, and a handle. Five power displays are respectively embedded and fixedly connected to the power cabinet. The heat dissipation mechanism is fixed at the lower end of the power cabinet. When the power cabinet encounters humid weather outdoors, the moisture-proof pipe on the dustproof device can prevent external moisture from entering the power cabinet through the dustproof device, thus preventing damage to the internal wiring. The moisture-blocking groove on the closed opening plate effectively blocks external moisture. The water-absorbing sheet collects condensed water droplets, and the pressing roller squeezes the water in the water-absorbing sheet into the drainage trough. The drainage plate in the drainage trough then discharges most of the water, preventing condensed water from remaining in the moisture-proof pipe for a long time and entering the power cabinet when the opening plate is reopened.
[0004] However, the aforementioned power cabinets are difficult to clean their own filters thoroughly, and long-term operation will cause dust accumulation, affecting their heat dissipation efficiency. Therefore, a power cabinet with dustproof function is proposed to solve the above-mentioned problems. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a power cabinet with dustproof function in view of the shortcomings of the prior art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a power cabinet with dustproof function, including a cabinet body, a cabinet door hinged to the left side of the cabinet body, a component board fixedly connected inside the cabinet body, an air outlet provided at the front of the cabinet body, a dust removal mechanism provided inside the cabinet body, a fire extinguishing mechanism provided inside the cabinet body, and a water cooling mechanism provided on the right side inside the cabinet body. The dust removal mechanism includes: a duct, fan blades, a bracket, a filter plate, an air inlet grille, and a motor. The duct is fixedly connected to the inner wall of the cabinet body, the bracket is fixedly connected to the inner wall of the duct, the motor is fixedly connected inside the bracket, the filter plate is fixedly connected to the inner wall of the duct, the fan blades are rotatably connected to the front of the bracket, the fan blades are fixedly connected to the output end of the motor, and the air inlet grille is movably connected to the rear of the cabinet body. The dust removal mechanism also includes: a mounting plate, a slider, a reciprocating screw, a friction wheel, and a cylindrical brush. The reciprocating screw is driven to the output end of the motor through a pulley set, and the reciprocating screw is rotatably connected to the left side of the duct. Inside the block, the slider is threadedly connected to the circumferential surface of the reciprocating screw. The mounting plate is fixedly connected to the right side of the slider. The friction wheel is rotatably connected inside the mounting plate and fixedly connected to both ends of the cylindrical brush. The cylindrical brush contacts the filter plate. When the power cabinet is working, the motor drives the fan blades to rotate, drawing in outside air through the air intake grille. The drawn-in air is filtered by the filter plate and enters the housing. At the same time, the motor rotates, driving the reciprocating screw to rotate via a belt. The rotation of the reciprocating screw drives the slider to move back and forth along the direction of the reciprocating screw. The movement of the slider drives the mounting plate to move, and the movement of the mounting plate drives the friction wheel to move on the surface of the filter plate. The friction wheel contacts and rubs against the filter plate, causing the friction wheel to rotate. The rotation of the friction wheel drives the cylindrical brush to rotate, which in turn brushes the filter plate. With the reciprocating movement of the mounting plate, the cylindrical brush can thoroughly brush the dust and lint off the surface of the filter plate and brush it to the bottom of the channel, improving air intake efficiency and preventing internal high temperature from affecting the operation of electrical components. When too much dust accumulates at the bottom of the channel, it can be cleaned by disassembling the air intake grille.
[0007] Preferably, the fire extinguishing mechanism includes: a nozzle, an air hose, a sensing valve, and a gas cylinder. The gas cylinder is fixedly connected to the inner wall of the housing, the sensing valve is fixedly connected to the top of the gas cylinder, and the nozzle is fixedly connected to the outlet of the sensing valve via the air hose. The fire extinguishing mechanism also includes: a partition, an electric slide rail, a push rod, a pawl, and a stop. The partition is slidably connected to the inner wall of the housing, the electric slide rail is fixedly connected to the inner wall of the housing, the push rod is fixedly connected to the bottom of the partition, the pawl is slidably connected to the inner wall of the housing via a spring, the stop is fixedly connected to the inner wall of the housing, the nozzle is slidably connected to the moving end of the electric slide rail, the stop contacts the partition, and the push rod is slidably connected to the moving end of the electric slide rail. When an accident occurs inside the power cabinet and the sensing valve detects high temperature or flame, the extinguishing agent from the sensing valve travels through the gas pipe to the nozzle, spraying out from multiple holes in the nozzle. Simultaneously, the electric slide rail starts, causing the nozzle to reciprocate and quickly fill the entire cabinet with extinguishing agent. As the nozzle reciprocates, it pushes the push rod, which in turn moves the partition upward. At this point, the ratchet on the left side of the partition pushes the pawl to the left via the inclined plane, compressing the spring. When the partition completely seals the air duct passage, the spring resets, pushing the pawl into the ratchet, achieving one-way locking. At this time, the air inlet closes, and the extinguishing agent gradually fills the cabinet, expelling air through the air outlet, isolating oxygen to extinguish the fire, preventing the fire from spreading further, and ensuring the safety of life and property.
[0008] Preferably, the water-cooling mechanism includes: fins, a water outlet pipe, a protective box, and a water tank. The fins are fixedly connected to the inside of the housing, the water outlet pipe is fixedly connected to the top of the inner wall of the housing, the protective box is fixedly connected to the rear of the housing, and the water tank is movably connected to the back of the housing. The system comprises a water-dispensing wheel, a gear, and a U-shaped rack. The gear is rotatably connected inside the cabinet, the water-dispensing wheel is fixedly connected to the right side of the gear, and the U-shaped rack is fixedly connected to the right side of the slider. The gear meshes with the U-shaped rack, and the top of the U-shaped rack contacts the cabinet. When the temperature inside the power cabinet is too high and air circulation is insufficient for effective cooling, cooling water is sprayed out from the outlet pipe. Simultaneously, the movement of the slider causes the U-shaped rack to reciprocate, driving the meshing gear to rotate. The gear's rotation, in turn, rotates the water-dispensing wheel, which splashes the cooling water flowing from the outlet pipe onto the fins inside the cabinet. The fins significantly increase the heat dissipation surface area, enhancing heat transfer efficiency and quickly dissipating heat from inside the cabinet to prevent the electrical components from overheating and degrading, thus avoiding the risk of performance degradation. After emergency cooling, the outflowing coolant is collected in a water tank outside the cabinet for future use.
[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This dustproof power cabinet achieves efficient ventilation and dust removal through the cooperation of the following components: air duct, fan blade, bracket, mounting plate, filter plate, slider, reciprocating screw, friction wheel, cylindrical brush, air intake grille, and motor. It can also perform self-cleaning to prevent filter plate blockage from affecting air intake efficiency.
[0010] 2. This dustproof power cabinet, through the cooperation of partitions, nozzles, air pipes, sensor valves, air cylinders, electric slide rails, push rods, inclined blocks, and stops, can achieve emergency handling in the event of a fire, effectively extinguishing the fire and preventing its spread from affecting life and property safety.
[0011] 3. This dustproof power cabinet, through the cooperation of water-dispensing wheel, gear, U-shaped rack, fins, water outlet pipe, protective box, and water tank, can achieve emergency cooling of the device to prevent accidents, protect electrical components from damage or performance impairment at high temperatures, and collect coolant for future use.

[0014] 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.
[0015] Please see Figures 1-9 One embodiment of the present invention is as follows: a power cabinet with dustproof function includes a cabinet body 1, a cabinet door 2 hinged to the left side of the cabinet body 1, a component board 3 fixedly connected inside the cabinet body 1, an air outlet 4 provided at the front of the cabinet body 1, a dust removal mechanism 5 and a fire extinguishing mechanism 6 provided inside the cabinet body 1, and a water cooling mechanism 7 provided on the right side inside the cabinet body 1. The dust removal mechanism 5 includes: a duct 501, a fan blade 502, a bracket 503, a filter plate 505, an air inlet grille 510, and a motor 511. The duct 501 is fixedly connected to the inner wall of the cabinet body 1, the bracket 503 is fixedly connected to the inner wall of the duct 501, the motor 511 is fixedly connected inside the bracket 503, the filter plate 505 is fixedly connected to the inner wall of the duct 501, and the fan blade 502 is rotatably connected to the front of the bracket 503. Connected to the output end of motor 511, the air intake grille 510 is fixedly connected to the inlet of duct 501. The dust removal mechanism 5 also includes: mounting plate 504, slider 506, reciprocating screw 507, friction wheel 508, and cylindrical brush 509. The reciprocating screw 507 is connected to the output end of motor 511 via belt drive. The reciprocating screw 507 is rotatably connected to the inside of the left connecting block of duct 501. The slider 506 is threadedly connected to the circumferential surface of the reciprocating screw 507. The mounting plate 504 is fixedly connected to the right side of the slider 506. The friction wheel 508 is rotatably connected to the inside of the mounting plate 504. The friction wheel 508 is fixedly connected to both ends of the cylindrical brush 509. The cylindrical brush 509 contacts the filter plate 505, which can achieve efficient ventilation and dust removal effect of the device, and can also perform self-cleaning to prevent the filter plate from being blocked and affecting the air intake efficiency.
[0016] Working principle: When the power cabinet is working, the motor 511 drives the fan blade 502 to rotate, drawing in outside air through the air intake grille 510. The drawn-in air is filtered by the filter plate 505 and then enters the housing 1. At the same time, the motor 511 rotates, driving the reciprocating screw 507 to rotate via a belt. The rotation of the reciprocating screw 507 drives the slider 506 to move back and forth along the direction of the reciprocating screw 507. The movement of the slider 506 drives the mounting plate 504 to move. The movement of the mounting plate 504 drives the friction wheel 508 to move on the surface of the filter plate 505. The friction wheel 508 contacts and rubs against the filter plate 505, causing the friction wheel 508 to rotate. The rotation of the friction wheel 508 drives the cylindrical brush 509 to rotate. The rotation of the cylindrical brush 509 brushes the filter plate 505. With the reciprocating movement of the mounting plate 504, the cylindrical brush 509 can thoroughly brush the dust and lint on the surface of the filter plate 505, brushing it off to the bottom of the channel, improving air intake efficiency and preventing the internal high temperature from affecting the operation of electrical components. When too much dust accumulates at the bottom of the channel, it can be cleaned by disassembling the air intake grille 510.
[0017] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the fire extinguishing mechanism 6 includes: a nozzle 602, an air pipe 603, a sensing valve 604, and a gas cylinder 605. The gas cylinder 605 is fixedly connected to the inner wall of the housing 1, the sensing valve 604 is fixedly connected to the top of the gas cylinder 605, and the nozzle 602 is fixedly connected to the outlet end of the sensing valve 604 through the air pipe 603. The fire extinguishing mechanism 6 also includes: a partition 601, an electric slide rail 606, a push rod 607, a pawl 608, and a stop block 609. The partition 601 is slidably connected to... Inside the housing 1, an electric slide rail 606 is fixedly connected to the inner wall of the housing 1, a push rod 607 is fixedly connected to the bottom of the partition 601, a pawl 608 is slidably connected to the inner wall of the housing 1 via a spring, a stop block 609 is fixedly connected to the inner wall of the housing 1, a nozzle 602 is slidably connected to the moving end of the electric slide rail 606, the stop block 609 contacts the partition 601, and the push rod 607 is slidably connected to the moving end of the electric slide rail 606. This configuration enables emergency response to fires, effectively extinguishing fires and preventing the spread of fires that could affect life and property safety.
[0018] The water cooling mechanism 7 includes: fins 704, water outlet pipe 705, protective box 706, and water tank 707. The fins 704 are fixedly connected to the inside of the housing 1, the water outlet pipe 705 is fixedly connected to the top of the inner wall of the housing 1, the protective box 706 is fixedly connected to the rear of the housing 1, and the water tank 707 is movably connected to the back of the housing 1. It also includes a water-dispensing wheel 701, a gear 702, and a U-shaped rack 703. The gear 702 is rotatably connected to the inside of the housing 1, the water-dispensing wheel 701 is fixedly connected to the right side of the gear 702, and the U-shaped rack 703 is fixedly connected to the right side of the slider 506. The gear 702 meshes with the U-shaped rack 703, and the top of the U-shaped rack 703 contacts the housing 1. This mechanism enables emergency cooling of the device to prevent accidents, protects electrical components from damage or performance degradation at high temperatures, and collects coolant for future use.
[0019] Working principle: When an accident occurs in the power cabinet, the sensing valve 604 senses high temperature or flame. The extinguishing agent in the sensing valve 604 flows through the gas pipe 603 to the nozzle 602 and is sprayed out from multiple holes in the nozzle 602. At the same time, the electric slide rail 606 starts, driving the nozzle 602 to move back and forth quickly to fill the entire box 1 with extinguishing agent. When the nozzle 602 moves back and forth, it pushes the push rod 607 to move. The push rod 607 moves the partition 601 upward. At this time, the ratchet on the left side of the partition 601 will push the pawl 608 to the left through the inclined surface and compress the spring. When the partition 601 completely seals the air duct 501 channel, the spring resets and pushes the pawl 608 to lock between the ratchet teeth, realizing one-way locking. At this time, the air inlet is closed and the extinguishing agent gradually fills the box 1 and exhausts the air through the air outlet 4, isolating oxygen to extinguish the fire and prevent the fire from spreading further, thus ensuring the safety of life and property.
[0020] When the temperature inside the power cabinet becomes too high and air circulation is insufficient for effective cooling, cooling water is sprayed out from the outlet pipe 705. Simultaneously, the movement of the slider 506 drives the U-shaped rack 703 to reciprocate. This reciprocating motion of the U-shaped rack 703 drives the meshing gear 702 to rotate. The rotation of the gear 702 drives the water-dispensing wheel 701 to rotate, which in turn splashes the cooling water flowing from the outlet pipe 705 onto the fins 704 inside the cavity. The fins 704 significantly increase the heat dissipation surface area, enhancing heat transfer efficiency and quickly dissipating heat from inside the cabinet 1, preventing the electrical components from overheating and degrading their performance, thus avoiding the risks associated with these components. After emergency cooling is completed, the coolant flowing out is collected in the water tank 707 outside the cabinet 1 for future use.

There are many methods and approaches to implement this technical solution; the above description is merely a preferred embodiment of the invention.
