Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and particularly to a high and low voltage power distribution cabinet with controllable heat dissipation for outdoor use. Background Art

[0002] A high and low voltage power distribution cabinet is a device used for power distribution, control, protection, and monitoring of electrical equipment in the power system, and it is crucial in the power system. Its design and selection must be customized according to specific power requirements, usage environments, and safety requirements to ensure the efficient and safe distribution and use of electricity. Therefore, for some high and low voltage power distribution cabinets working outdoors, high and low voltage power distribution cabinets that can be used outdoors need to be selected.

[0003] However, there are some problems in the actual working process of existing high and low voltage power distribution cabinets for outdoor use. For example, for a high and low voltage power distribution cabinet with the publication number CN112670872B, during its working process, when an internal electrical component catches fire, although it can use an expansion airbag to quickly expand to contact the air and extinguish the fire by physical means, its fire extinguishing effect is poor. Only using the friction of the expansion airbag cannot effectively extinguish the fire, and it cannot automatically cut off the power supply and isolate the outside air during a fire. Therefore, the outside air will continuously supply oxygen for combustion, and the fire may spread through the circuit, resulting in a larger fire. Moreover, during its actual working process, it cannot adjust the internal heat dissipation performance according to the outdoor temperature, with poor practicability and low safety. Therefore, a high and low voltage power distribution cabinet with controllable heat dissipation for outdoor use needs to be provided to meet the needs of users. Summary of the Invention

[0015] The working principle and beneficial effects of the present invention are as follows: 1. An automatic partition component is provided in the present invention. When a short circuit occurs in the power distribution cabinet during operation and causes a fire, the hydraulic rod can drive the connecting frame to move downward, and can drive the cutting knife and the first baffle to move downward simultaneously through the fixed rod. At this time, under the movement of the cutting knife, the power cord can be automatically cut off, preventing the fire from spreading and causing an explosion of the electrical equipment inside the power distribution cabinet, and at the same time ensuring the safety of subsequent fire extinguishing work. Meanwhile, under the combined action of the connecting frame and the first baffle, the first filter plate at the air inlet and the second filter plate at the air outlet can be automatically closed, preventing oxygen in the external air from continuously being transported into the power distribution cabinet and causing the fire to spread. At this time, the oxygen content in the cabinet continuously decreases, which can hinder the continuous combustion of electrical components and accelerate the subsequent fire extinguishing speed.

[0016] 2. A multi-functional heat dissipation component is provided in the present invention. Under the driving action of the servo motor, through the meshing between the first circular gear, the second circular gear, and the third circular gear, each screw rod and the exhaust fans on both sides can be driven to rotate simultaneously. At this time, each screw rod can push the refrigerated fire-fighting liquid inside the heat insulation box to circulate in the heat conduction pipe. Using the principle of heat exchange, the heat conduction pipe can quickly cool the air at the air inlet. Combined with the exhaust fans, the interior of the power distribution cabinet can be efficiently cooled and dissipated, ensuring the stability and safety of the long-term working state of the power distribution cabinet. When a short circuit occurs in the power distribution cabinet during operation and causes a fire, under the downward movement of the connecting frame, the conveying cylinders can be automatically pushed to move towards the side through the guide wheels on the sliding rod, and then the first through holes on the conveying cylinders can be aligned with the second through holes on the first shunt pipes. At this time, the refrigerated fire-fighting liquid inside the heat insulation box can be automatically sprayed through the nozzles on each second shunt pipe, realizing automatic fire extinguishing treatment, increasing the diversity and safety of the use of high and low voltage power distribution cabinets.

[0017] 3. In the present invention, a turntable and a sponge board are provided. When the outdoor high and low voltage power distribution cabinet works in summer, the solenoid valve on the diversion pipe can be opened. At this time, the water in the water storage tank can be automatically and intermittently conveyed into the sponge board through the third through holes on the turntable. By using the evaporation heat absorption of the water, the air at the air inlet can be further cooled, which can further improve the heat dissipation effect. In spring and autumn, the solenoid valve on the diversion pipe can be closed, and in winter, the refrigerating sheet can also be closed, realizing the convenient regulation of the heat dissipation performance and ensuring the stability and safety of the outdoor high and low voltage power distribution cabinet when it works in summer.

Under the action of the downward movement of the connecting frame 402, the guiding wheels 528 on the sliding rods 527 can push each conveying cylinder 515 to automatically move towards the side, so that the first through holes 518 on the conveying cylinder 515 can be aligned with the second through holes 523 on the first shunt pipe 522. At this time, the fire-fighting liquid cooled inside the heat insulation box 501 can be automatically sprayed through the nozzles 525 on each second shunt pipe 524 to achieve automatic fire extinguishing treatment.

[0031] It should be noted that the present invention is a high and low voltage power distribution cabinet with controllable heat dissipation for outdoor use. First, the staff can pass the power cord 408 through the first sealing ring 407 on the fixed frame 406, and then connect it to the electrical components inside the power distribution cabinet. At this time, the staff can rotate the threaded rod 410 on the fixed frame 406, and the connecting sleeve rod 411 connected by thread can drive the clamping plate 412 to move stably downward inside the fixed frame 406. The rectangular clamping plate 412 is attached to and limited by the inner wall of the fixed frame 406 and can move stably downward. Combined with the support plate 409, the power cord 408 can be stably clamped and fixed, ensuring the stable connection state of the power cord 408 and preventing the power cord 408 from loosening and causing poor contact. And under the clamping action of the power cord 408, it can ensure that the subsequent emergency isolation work can be completed stably.

[0032] During the operation of the high and low voltage power distribution cabinet, driven by the servo motor 503, the first circular gear 504 can be driven to rotate, and then the second circular gears 505 on both sides can be driven to mesh and rotate. The second circular gears 505 on both sides can drive the corresponding third circular gears 506 to rotate stably. Under the rotation of the third circular gear 506, the exhaust fan 530 can be driven to rotate stably through the second rotating shaft 529. At this time, external air enters through the first filter plate 14 and then discharges from the second filter plate 16 to complete air circulation, thereby cooling and dissipating heat inside the power distribution cabinet.

[0033] In the initial state, the first through hole 518 on one side of the conveying cylinder 515 is aligned with the heat conducting pipe 520, while the first through hole 518 on the other side of the conveying cylinder 515 is not aligned with the second through hole 523 on the first shunt pipe 522. And under the fitting action of the rubber plate 517 and the first shunt pipe 522, the first through hole 518 on the other side of the conveying cylinder 515 is in a closed state. At this time, under the rotation of the second circular gear 505, the first bevel gear 508 at the bottom can be driven to rotate through the first rotating shaft 507, and then the sleeve 510 can be driven to rotate stably on the corresponding fixed plate 511 through the second bevel gears 509 meshed on both sides. At this time, the sleeve 510 can drive the screw rod 514 to rotate stably in the conveying cylinder 515 through the limiting rod 513. Under the continuous rotation of the screw rod 514, the fire extinguishing liquid in the heat insulation box 501 can be conveyed into the heat conducting pipe 520 through the first through hole 518 on the conveying cylinder 515, and then the fire extinguishing liquid is conveyed to the heat insulation box 501 through the other end of the heat conducting pipe 520 to complete the circulating flow. During the circulating flow of the fire extinguishing liquid, the heat insulation box 501 can be continuously cooled by the refrigerating sheet 531 on it. During the circulating flow of the refrigerated fire extinguishing liquid, the air entering through the first filter plate 14 can be quickly cooled through the heat conducting pipe 520, thereby effectively improving the cooling and heat dissipation effect inside the power distribution cabinet.

[0034] When the outdoor high and low voltage power distribution cabinet works in summer, the solenoid valve on the diversion pipe 10 can be opened. At this time, the water in the water storage tank 8 can automatically flow to the turntable 11 through the diversion pipe 10. During the rotation of the second rotating shaft 529, not only can the exhaust fan 530 be driven to rotate, but also the turntable 11 can be driven to rotate synchronously. At this time, under the continuous rotation of the turntable 11, the third through holes 12 on both sides can be aligned with the diversion pipe 10 at intervals. At this time, the water in the diversion pipe 10 can be automatically and intermittently conveyed into the sponge plate 13. By using the evaporation heat absorption of the moisture inside the sponge plate 13, the air at the air inlet can be further cooled, thereby further improving the heat dissipation effect. In spring and autumn, the solenoid valve on the diversion pipe 10 can be closed, and the refrigerating sheet 531 can also be closed in winter to realize the convenient regulation of the heat dissipation performance.

[0035] When a short circuit occurs in the circuit during the operation of the power distribution cabinet, causing a fire, the smoke sensor 6 can drive the hydraulic rod 401 through the central control system of the power distribution cabinet. At this time, the hydraulic rod 401 can drive the connecting frame 402 to move downward, and can drive the cutting knife 404 and the first baffle 405 to move downward simultaneously through the fixing rod 403. At this time, under the movement of the cutting knife 404, the power cord 408 can be automatically cut off, avoiding the explosion of electrical equipment inside the power distribution cabinet caused by the expansion of the fire, and ensuring the safety of subsequent fire extinguishing work; at the same time, under the movement of the connecting frame 402, the first filter plate 14 at the air inlet can be automatically closed, and under the movement of the first baffle 405, the second filter plate 16 at the air outlet can be automatically closed, preventing oxygen in the outside air from continuously being transported into the power distribution cabinet and causing the fire to spread. At this time, the oxygen content in the cabinet continues to decrease, which can hinder the continuous combustion of electrical components and accelerate the subsequent fire extinguishing speed.

[0036] Under the downward movement of the connecting frame 402, the sliding rods 527 in each of the second sealing rings 526 can be driven to move downward automatically. Furthermore, the sliding rods 527 can contact the guiding blocks 519 on the corresponding conveying cylinders 515 through the guiding wheels 528. Under the guiding action of the inclined surface at the top of the guiding block 519, the sliding rods 527 can drive each of the conveying cylinders 515 to move automatically to the side through the guiding wheels 528. At this time, the first through hole 518 on one side of the conveying cylinder 515 is misaligned with the heat conducting pipe 520, and under the fitting action of the second baffle 521 and the rubber plate 517, the first through hole 518 on one side of the conveying cylinder 515 can be closed. At this time, the fire extinguishing liquid will not continue to circulate in the heat conducting pipe 520.

[0037] At the same time, under the movement of the conveying cylinder 515, the first through hole 518 on the other side of the conveying cylinder 515 is aligned with the second through hole 523 on the first shunt pipe 522; when the conveying cylinder 515 moves to the side, it can drive the sliding rod 527 to move outside the sleeve 510 by driving the screw rod 514, but it will not break away from the sleeve 510. Therefore, the sleeve 510 can still drive the screw rod 514 to rotate stably through the sliding rod 527. At this time, under the continuous rotation of each screw rod 514, the refrigerated fire extinguishing liquid inside the heat insulation box 501 can be stably transported into the first shunt pipe 522 through the first through hole 518 and the second through hole 523, and then automatically sprayed through the nozzles 525 on each of the second shunt pipes 524 to achieve automatic fire extinguishing treatment.

[0038] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
