Technical Field

[0001] The present invention belongs to the technical field of power equipment, and particularly relates to a protection device for high-voltage distribution equipment. Background Art

[0002] High-voltage distribution equipment is a device used for transmitting and distributing high-voltage electric energy in a power system. It includes various devices such as high-voltage switch cabinets, circuit breakers, and instrument transformers. It can control the on-off of the circuit during normal system operation and cooperate with relay protection to cut off the current during a fault to ensure the safety of the system. Its voltage level is generally between 3.6 kV and 550 kV. The ventilation holes of traditional high-voltage distribution equipment are generally exposed externally. When a large amount of dust accumulates on the surface area of the through holes, it is very easy for the dust to enter the interior of the high-voltage distribution equipment, which affects the internal electrical components. Moreover, the protection of the internal electrical components of the high-voltage distribution equipment only relies on the protection of the outer shell. Such simple protection is very likely to cause damage to the internal electrical components when the high-voltage distribution equipment is impacted. Summary of the Invention

When this situation is not triggered, this strengthening structure is retracted, which facilitates the staff to repair the inside of the high-voltage switchgear body 1, achieving the effect of facilitating dust prevention and protection for the high-voltage switchgear body 1.

[0030] Embodiment 2: Based on Embodiment 1, referring to Figure 3 、 Figure 5 and Figure 6The dustproof component 4 includes a connecting shell 401, and two groups of connecting shells 401 are respectively welded to the surface of the high-voltage distribution cabinet body 1 near the ventilation hole 3. The first dustproof net 402 is detachably connected inside the two groups of connecting shells 401. A bellows 422 is bonded to one side of the two groups of connecting shells 401, and a second dustproof net 410 is bonded to the other side of the bellows 422. Baffles 407 are slidably connected inside the two groups of connecting shells 401; a second inclined block 408 is welded to one side of the two groups of baffles 407, and five groups of vibration plates 406 are bonded to the inside of the two groups of second dustproof nets 410, and a first inclined block 405 is welded to one side of the five groups of vibration plates 406. One end of one side of the five groups of vibration plates 406 is bolted to a first spring top rod 404, and a first connecting plate 403 is fixedly connected between the first spring top rod 404 and the connecting shell 401; limiting plates 411 are welded on both sides of the surface of the high-voltage distribution cabinet body 1, and the two groups The surfaces of the limiting plates 411 are slidably connected with connecting rods 413, one end of the two groups of connecting rods 413 are welded with extrusion shells 414, and one side of the two groups of extrusion shells 414 is welded with extrusion rods 409; one end of the two groups of connecting rods 413 is welded with fixing rods 412, and one side of the fixing rods 412 is provided with a plurality of groups of teeth, the lower surfaces of the two groups of connecting shells 401 are threadedly connected with five groups of exhaust fan housings 415, and the insides of the five groups of exhaust fan housings 415 are rotatably connected with fan blades 419; one end of the five groups of fan blades 419 are welded with first pinion gears 420, one end of one group of the first pinion gears 420 is fixedly connected with the second pinion gear 421, and the five groups of the first pinion gears 420 are commonly connected by a chain 416 for transmission, one side of the lower end of the connecting shell 401 is fixedly connected with a rotating shaft 418, one side of the rotating shaft 418 is fixedly connected with a large gear 417, and the large gear 417 and the second pinion gear 421 are meshingly connected.

[0031] Brief description of the usage process: When the ejector case 506 uses the diagonal rod 505 to push the fixed rod 412, the fixed rod 412 will drive the extrusion case 414 to extrude the first inclined block 405 through the connecting rod 413. Since the two sides of the first inclined block 405 are inclined planes, the first inclined block 405 will drive the vibrating plate 406 to retract using the first spring ejector rod 404. When the extrusion case 414 continues to move, the first spring ejector rod 404 will drive the vibrating plate 406 to reset. And while the vibrating plate 406 vibrates the second dust-proof net 410, the dust on the surface of the second dust-proof net 410 will fall off. And in this process, the extrusion rod 409 will move along with the extrusion case 414, causing the extrusion rod 409 to disengage from the extrusion of the second inclined block 408, so that the baffle 407 falls inside the connecting case 401, preventing dust from passing through the second dust-proof net 410 and entering the ventilation hole 3. The first dust-proof net 402 is provided to prevent the baffle 407 from failing to isolate the dust infiltrating from the second dust-proof net 410. The first dust-proof net 402 can be disassembled for cleaning. And when the fixed rod 412 moves, the teeth on its surface will also drive the large gear 417 to rotate using the rotating shaft 418, and the large gear 417 will drive the second small gear 421 to rotate. Due to the transmission ratio between the large gear 417 and the second small gear 421, when the large gear 417 rotates one circle, it will drive the second small gear 421 to rotate several circles. While the second small gear 421 drives one group of the first small gears 420 and the fan blades 419 to rotate, it will drive the other four groups of the first small gears 420 and the fan blades 419 to rotate using the chain 416. The rotation of the fan blades 419 can discharge the dust floating inside the connecting case 401, achieving the effect of an exhaust fan. In the whole process, these functions are realized synchronously, achieving the effect of facilitating dust prevention for the ventilation hole 3 and dust removal for the dust-proof component 4.

[0032] Embodiment 3: Based on Embodiment 2, referring to Figure 4 and Figure 7, the protection component 5 includes a slide plate 501, a spring pull rod 502 and a second protection plate 504. Two groups of slide plates 501 are respectively welded to both sides of the upper end of the bottom plate 2. A first protection plate 503 is slidably connected between the two groups of slide plates 501. Two groups of spring pull rods 502 are respectively fixedly connected between the two groups of slide plates 501 and the first protection plate 503. Push columns 509 are welded to the upper ends of the other side of the first protection plate 503. Two groups of rotating columns 513 are welded to the upper end of the bottom plate 2 near one side of the high-voltage power distribution cabinet body 1. Two groups of arc-shaped rods 512 are welded to the upper end of the bottom plate 2. The surfaces of the two groups of rotating columns 513 are rotatably connected with third protection plates 517, and the third protection plates 517 are slidably connected with the arc-shaped rods 512. Sliders 515 are slidably connected inside the two groups of third protection plates 517. Rotating rods 514 are rotatably connected inside the two groups of sliders 515. Cross bars 516 are welded to the surfaces of the two groups of rotating rods 514. One ends of the two groups of cross bars 516 are jointly welded with a push shell 506. Oblique rods 505 are welded to one ends of both sides of the push shell 506. The two groups of oblique rods 505 are respectively fixedly connected to one ends of the two groups of fixed rods 412. A positioning shell 507 is welded to the upper end of the bottom plate 2 near one side of the push shell 506. Second spring ejector rods 508 are bolted inside the two groups of third protection plates 517. The piston ends of the two groups of second spring ejector rods 508 are bolted with second protection plates 504, and the second protection plates 504 are slidably connected with the third protection plates 517. Third spring ejector rods 511 are bolted to one ends of one side of the two groups of third protection plates 517. The piston ends of the two groups of third spring ejector rods 511 are bolted with retaining shells 510.

[0033] Brief description of the usage process: The holes on the surface of the positioning shell 507 are used to fix the push shell 506 by passing a lock through it to prevent people from operating it casually. When the push shell 506 is pushed, the push shell 506 will operate by using the oblique rod 505, and will drive the cross bar 516 to push the third protection plate 517, so that the third protection plate 517 will rotate and open by using the rotating column 513, which is convenient for the staff to repair the high-voltage power distribution cabinet body 1. And when the cross bar 516 is being pushed, while the cross bar 516 rotates inside the slider 515 by using the rotating rod 514, the slider 515 will slide inside the third protection plate 517, which can prevent jamming. And when there is an impact object rushing towards the high-voltage power distribution cabinet body 1, the impact object will first touch the first protection plate 503. After the first protection plate 503 is impacted, it will slide on the surface of the slide plate 501, thereby driving the push column 509 to push the retaining shell 510, so that the retaining shell 510 retracts by using the third spring ejector rod 511. At this time, the second spring ejector rod 508 will drive the second protection plate 504 to suddenly pop out to strengthen the protection of the protection component 5. When the second protection plate 504 is not in use, the second protection plate 504 will be pulled out and fixed, so as to leave enough space for the staff to repair the high-voltage power distribution cabinet body 1. The spring pull rod 502 is used to pull the first protection plate 503 back to its original position, achieving the effect of facilitating the protection of the high-voltage power distribution cabinet body 1.
