As a technical optimization scheme of the invention, the outer wall of the protective cover 4 is connected with a layer of protective air bag 13, and the air inlet end of the protective air bag 13 is connected with the air outlet end of the air pump on the top plate 7. The cabinet body 1 can be with filling gas in the outside protective airbag 13 of protection casing 4 in the transportation, and the outside at the cabinet body 1 of the cover 4 expansion suit, the dual function of protective airbag 13 and protection casing 4 can carry out abundant protection to the cabinet body 1 for the cabinet body 1 obtains good protection in the transportation, is difficult for taking place to damage.
When the invention is used, the cabinet body 1 is moved to a preset position for installation, and the internal instrument is connected with an external circuit, and the electric wires extend outwards from the bottom of the cabinet body 1 after connection. And the door plate 2 is closed, the joint of the door plate 2 and the cabinet body 1 is sealed by adopting the sealing air bag 10, and carbon dioxide is filled in the sealing air bag 10 in advance. Finally, the winding motor 9 is started to run, the second pull rope 25 is continuously extended outwards, the protective cover 4 moves downwards under the action of the gravity of the balancing weight 16, and finally the protective cover 4 is sleeved outside the cabinet body 1.
The protection casing 4 cover can be isolated the cabinet body 1 with external environment in the outside of the cabinet body 1, and then makes the dust impurity in the external environment can not fall on the cabinet body 1, has guaranteed the security of the cabinet body 1 when the dust is great or other adverse circumstances use, and outside dust is difficult for entering into the inside of the cabinet body 1 and causes damage or influence its job stabilization nature to various electrical apparatus original paper.
In use, the cooling liquid in the storage tank 6 enters the cooling pipe 14 under the delivery of the internal water pump, the cooling liquid flows from the cooling pipe 14 above to the cooling pipe 14 below, and in the flowing process, the cooling liquid absorbs the heat emitted outwards in the operation of the cabinet body 1 and finally carries the heat back to the inside of the storage tank 6. The cabinet body 1 is guaranteed to keep a good working state in the dustproof process, and the working stability of internal electrical components cannot be affected by high temperature. The cooling liquid continuously circulates and flows, and a good cooling effect can be maintained.
And fan 8 can forward rotation in the use of protection casing 4, outwards take out the dust or other impurity that get into with the inside gas of protection casing 4 and outside through dust absorption hole 11 for be difficult for remaining dust impurity between protection casing 4 and the cabinet body 1, can further dispel the heat to the cabinet body 1 simultaneously. In addition, in order to better clean dust and impurities outside the cabinet body 1, the protective cover 4 can be driven to be rolled up or unfolded down by utilizing the operation of the rolling motor 9, so that the balancing weight 16 moves up and down, and the cleaning brush 15 on the inner side cleans the outside of the cabinet body 1, so that the outside of the cabinet body 1 can be kept clean. Dust impurities generated by the cleaning enter the bristles of the cleaning brush 15 to be stored. After long-time use, when the brush hair of the cleaning brush 15 needs to be cleaned, the fan 8 reversely rotates, the dust collection hole 11 is used for blowing air between the protective cover 4 and the cabinet body 1, finally the blown air passes through the brush hair of the cleaning brush 15 and is discharged outwards, and when the air passes through the brush hair, the residual dust and impurities in the brush hair can be brought to the outside, so that the cleaning brush 15 is cleaned. And the cleaning brush 15 can play a certain filtering role at the bottom, so that dust and impurities are prevented from entering between the protective cover 4 and the cabinet body 1 from the lower part.
The sealing air bag 10 not only can seal the joint between the door plate 2 and the cabinet body 1, but also can play a role in extinguishing fire after the fire disaster occurs in the cabinet body 1. When the fire condition occurs in the cabinet body 1, after the temperature value detected by the temperature sensor 3 is higher than a preset value, an internal signal is transmitted to a preset control system, and then an alarm signal is sent out from the control system, so that the personnel can rescue timely. When the internal temperature is too high or the fire is large, the sealing air bag 10 is burned, and carbon dioxide gas in the sealing air bag 10 is emitted outwards to play a certain role in fire extinguishment. At the same time, after the sealing air bag 10 is broken, the first pull rope 20 loses pulling force, and the return spring 23 pulls the pressing plate 24 to move in the loading cavity 21 until the pressing plate 24 presses the start-stop switch 22. After the start-stop switch 22 is extruded, the electromagnetic valve 18 and the fire-fighting equipment in the loading box 5 are started to operate, fire-extinguishing materials enter the air pipe 19 from the conveying pipe 17, the fan 8 reversely rotates to blow air to the inside of the protective cover 4, and then the fire-extinguishing materials are blown and distributed between the protective cover 4 and the cabinet body 1, so that the cabinet body 1 can be protected, the fire in the cabinet body 1 is prevented from spreading to the outside, and the safety of the cabinet body 1 in use is ensured. When the fire-fighting equipment works, only on the premise that the temperature detected by the temperature sensor 3 is larger than a preset value and the sealing air bag 10 is broken. So that the fire-fighting equipment does not operate in the case that the sealing bladder 10 is worn and ruptured.
The cabinet body 1 can be with filling gas in the outside protective airbag 13 of protection casing 4 in the transportation, and the outside at the cabinet body 1 of the cover 4 expansion suit, the dual function of protective airbag 13 and protection casing 4 can carry out abundant protection to the cabinet body 1 for the cabinet body 1 obtains good protection in the transportation, is difficult for taking place to damage.
