Description

Technical Field

[0001] The invention relates to the technical field of switch cabinets, and in particular to a switch cabinet with a self-cleaning function. Background Art

[0002] Switchgear is a device used in power systems to control, protect and isolate electrical equipment. It is commonly used in power substations, distribution stations and industrial distribution systems to ensure a stable and safe supply of electricity. Switchgear is an important part of the power system, which can cut off the current when a system fault occurs and protect the equipment from damage.

[0003] Since a large number of circuits and switch controllers are integrated inside the switch cabinet, the circuits and switch controllers will generate a certain amount of heat when powered on. In order to avoid heat accumulation, the heat dissipation component is required to dissipate heat inside the switch cabinet. The heat dissipation component will exchange the air inside and outside the switch cabinet when working. In order to prevent the air from carrying dust into the switch cabinet during the exchange process, a filter is generally installed at the connection between the heat dissipation component and the switch cabinet. The filter will be blocked by dust during long-term use, which requires effective cleaning of the filter, otherwise it will affect the heat dissipation function of the switch cabinet. Therefore, a switch cabinet with a self-cleaning function is proposed. Summary of the invention

[0141] The first drain pipe 25 and the second drain pipe 33 are both made of hoses.

[0142] The first drain pipe 25 and the second drain pipe 33 are prevented from colliding and being damaged.

[0143] The diffusion device includes a second motor 38 and a diffusion fan 39 .

[0144] The axis of the second motor 38 is parallel to the axis of the first rotating shaft 6 , and is arranged inside the switch cabinet body 1 , close to the air inlet cross pipe 3 , and between the two air outlet pipes of the spiral tube 11 . The shell of the second motor 38 is fixedly connected to the inner wall of the switch cabinet body 1 .

The diffusion fan 39 is fixedly connected to the rotating shaft of the second motor 38, and its rotation axis coincides with its own axis.

[0146] When it is necessary to diffuse the air into the switch cabinet body 1, the staff starts the second motor 38 through the controller 40. The shaft of the second motor 38 drives the diffusion fan 39 to rotate. The diffusion fan 39 rotates to diffuse the air into the switch cabinet body 1, thereby expanding the contact area between the air and the inside of the switch cabinet body 1.

[0147] The upper end diameter of the collecting bucket 32 ​​is larger than the lower end diameter.

[0148] This enables the collecting bucket 32 ​​to effectively gather and collect small water droplets.

[0149] Working principle: in the rainy season or humid weather, when it is necessary to dissipate heat inside the switch cabinet body 1, the staff starts the first motor 8 and the thermoelectric cooler 13 through the controller 40, and the first motor 8 works. The rotating shaft of the first motor 8 drives the active bevel gear 9 to rotate, and the active bevel gear 9 drives the driven bevel gear 10 to rotate. The driven bevel gear 10 drives the first rotating shaft 6 to rotate, and the first rotating shaft 6 drives the fan 7 to rotate. The fan 7 drives the outside air to pass through the air intake vertical pipe 4, the air intake horizontal pipe 3, and the spiral tube 11 in sequence into the switch cabinet body 1, thereby dissipating heat inside the switch cabinet body 1, and then the air is discharged from the exhaust duct 5 with heat.

[0150] The thermoelectric cooler 13 works, the cooling end of the thermoelectric cooler 13 cools the first metal sheet 12 , and the first metal sheet 12 cools the spiral tube 11 , so that the temperature of the inner wall of the spiral tube 11 decreases.

[0151] When air passes through the filter 16 , the filter 16 filters dust therein.

[0152] When the air passes through the absorbent cotton 15, the absorbent cotton 15 initially absorbs moisture in the air.

[0153] When the air passes through the spiral tube 11, the air is centrifugally forced to adhere to the inner wall of the spiral tube 11 and gather into small water droplets, thereby further reducing the moisture in the air. The first metal sheet 12 cools the spiral tube 11, and the temperature of the inner wall of the spiral tube 11 is reduced, so that the water vapor in the air can be liquefied into small water droplets, thereby further reducing the water vapor in the air and preventing the air from entering the switch cabinet body 1 and making it humid. The gathered small water droplets enter the first cylinder body 22 through the first collecting pipe 23 and the first one-way valve.

[0154] When the air is discharged from the exhaust passage 5 with the heat inside the switch cabinet body 1, due to the low temperature of the outside, the water vapor in the air passing through the exhaust passage 5 will liquefy into small water droplets, and then the small water droplets will fall into the collecting bucket 32 ​​along the exhaust passage 5, and the water droplets will enter the second cylinder body 30 through the second collecting pipe 31 and the third one-way valve.

[0155] When the filter 16 needs to be cleaned, the staff controls the first electric telescopic rod 19 to extend through the controller 40, and the first electric telescopic rod 19 drives the cleaning plate 20 to move right, and the cleaning plate 20 drives the bristles 21 to move right, and the bristles 21 clean the filter 16. Then the first electric telescopic rod 19 contracts, and the telescopic rod of the first electric telescopic rod 19 drives the cleaning plate 20 to move left, and the cleaning plate 20 drives the bristles 21 to move left, and the bristles 21 clean the filter 16.

[0156] When it is necessary to diffuse the air into the switch cabinet body 1, the staff starts the second motor 38 through the controller 40. The shaft of the second motor 38 drives the diffusion fan 39 to rotate. The diffusion fan 39 rotates to diffuse the air into the switch cabinet body 1, thereby expanding the contact area between the air and the inside of the switch cabinet body 1.

[0157] When the water level in the first cylinder 22 contacts the first liquid level sensor 29, the first liquid level sensor 29 transmits a signal to the controller 40, and the controller 40 controls the second electric telescopic rod 27 to extend. The telescopic rod of the second electric telescopic rod 27 drives the first piston 26 to move upward, and the first piston 26 stretches the first spring 28, driving water to pass through the second one-way valve, the first drain pipe 25, and the water spray pipe 24 in sequence, and then sprayed from the plurality of nozzles at the bottom of the water spray pipe 24 to the filter 16, so as to flush the filter 16, thereby improving the cleaning efficiency of the filter 16 and saving water resources at the same time.

[0158] When the water in the first cylinder 22 is discharged, the first spring 28 contracts, and the first spring 28 drives the first piston 26 to move downward. The first piston 26 drives the air in the spiral tube 11 to enter the first cylinder 22 through the first collecting pipe 23 and the first one-way valve in sequence, so that the air pressure in the first cylinder 22 and the spiral tube 11 remains the same, so that the water droplets in the spiral tube 11 continue to gather in the first cylinder 22.

[0159] When the water level in the second cylinder 30 contacts the second liquid level sensor 37, the second liquid level sensor 37 transmits a signal to the controller 40, and the controller 40 controls the third electric telescopic rod 35 to extend. The telescopic rod of the third electric telescopic rod 35 drives the second piston 34 to move upward, and the second piston 34 stretches the second spring 36, driving water to pass through the fourth one-way valve, the second drain pipe 33, and the water spray pipe 24 in sequence, and then sprays toward the filter 16 from the plurality of nozzles at the bottom of the water spray pipe 24, so as to flush the filter 16, thereby improving the cleaning efficiency of the filter 16 and saving water resources at the same time.

[0160] When the water in the second cylinder 30 is discharged, the second spring 36 contracts, and the second spring 36 drives the second piston 34 to move downward. The second piston 34 drives the external air to enter the second cylinder 30 through the collecting bucket 32, the second collecting pipe 31, and the third one-way valve in sequence, so that the air pressure of the second cylinder 30 and the outside world remains the same, so that the water droplets in the exhaust channel 5 continue to gather in the second cylinder 30.
