After preliminary assembly is completed, each air pump 201 is controlled to be opened, the grooves of the air pumps are continuously pumped through the air pipes connected to the first clamping plates 203, the electric telescopic rods connected to the second clamping plates 206 are controlled to drive the electric telescopic rods to move towards the grooves, the second clamping plates 206 are all moved into the grooves of the first clamping plates 203, the electric telescopic rods connected to the sealing elements 204 are controlled to drive the electric telescopic rods to move towards the first clamping plates 203, the corrugated compensators connected between the electric telescopic rods are contracted, at the moment, due to the continuous pumping of the air pumps 201 and the movement of the second clamping plates 206, gas in the grooves of the first clamping plates 203 is extruded and pumped away, and the gas between the sealing elements 204 and the first clamping plates 203 is pumped away, so that the state of no gas in the space is maintained, the subsequent assembly work of the cabinet body 2 is realized, and at the same time, due to the fact that the air is in the state of being evacuated, the clamping of the grooves of the second clamping plates 206 and the first clamping plates 203 can be sealed for the second time, the gaps at the assembly position can be prevented from being permeated, and the moisture problem is avoided, at the moment, and the air can be completely sealed through the corrugated compensators, and the air can be prevented from entering the outside.

Example 2

On the basis of the embodiment 1, as shown in fig. 5-10, the device comprises a deflector 301, a rotating shaft 302 and a motor 303; a second ventilation groove 2005 is formed in the top of each cabinet 2, and each second ventilation groove 2005 is communicated with a corresponding air pump 201 through a communicating pipe 20101; a baffle 301 is disposed in each second ventilation groove 2005, and a ventilation opening 30101 is formed between the baffle 301 and the arc-shaped protrusion 2001, and the ventilation opening 30101 is communicated with the second ventilation grooves 2005; each guide plate 301 is fixedly connected with a rotating shaft 302, and each rotating shaft 302 is rotatably connected with the second ventilation groove 2005; a motor 303 is installed at the top of each cabinet 2, and the output end of each motor 303 is fixedly connected with a rotating shaft 302.

As shown in fig. 10, the deflector 301 is provided with a deflector concave 30102 for guiding the passing air flow to the surface of the arc-shaped protrusion 2001.

Also included is a connecting tube 401; a first ventilation groove 2003 is formed in the bottom of each cabinet body 2; each cabinet 2 is provided with a connecting pipe 401, and the connecting pipe 401 is communicated with a first ventilation groove 2003; an air pipe is provided at the bottom of the air pump 201 to communicate with the hollow 2004 for sucking the air inside the hollow.

Also included is an air tap 402; the bottom of each cabinet body 2 is provided with a plurality of air nozzles 402 which are symmetrically distributed in front-back direction, each air nozzle 402 is communicated with the first ventilation groove 2003, and the output direction of each air nozzle 402 faces the outer side of the cabinet body 2.

The invention works as follows:

When the ambient temperature is high and the air flow in the environment is small, the top surface of the uppermost cabinet 2 is subjected to solar irradiation to cause heat accumulation and difficult to dissipate, the heat in the cabinet 2 is easily increased for a long time to cause equipment damage, so that the motor 303 can be controlled to drive the guide plate 301 and the rotating shaft 302 to rotate to enable the ventilation opening 30101 to be communicated with the outside, as shown in the state of fig. 10, meanwhile, the air pump 201 is controlled to input air into the second ventilation groove 2005 through the communication pipe 20101 and blow the air out of the ventilation opening 30101 to the surface of the arc-shaped bulge 2001 to dissipate heat, and meanwhile, the motor 303 can be controlled to adjust the angles of the guide plate 301 and the rotating shaft 302 to adjust the size of the ventilation opening 30101, so that the size of the passing air is adjusted.

It should be noted that, as shown in fig. 10, the flow guiding concave 30102 is disposed on the flow guiding plate 301, so that a portion of the gas flowing from the second ventilation groove 2005 to the ventilation opening 30101 contacts with the flow guiding concave 30102, and the gas is guided to the surface of the arc-shaped protrusion 2001 after contacting with the flow guiding concave 30102, so that a portion of the gas flows along the surface of the arc-shaped protrusion 2001, thereby increasing the fluidity of the surface of the arc-shaped protrusion 2001 and increasing the efficiency of the gas to take heat away.

Through the arc grooves 2002 at the bottoms of the two bottom cabinet bodies 2 and the gaps of the supporting hollow bottom plate 102, gas enters and is introduced into the empty slots 2004 through the connecting pipes 401, then, the gas is input into the arc grooves 2002 of the upper cabinet body 2 from the vent 30101 of the bottom cabinet body 2 through the air pump 201 of the bottom cabinet body 2, and is further introduced into the empty slots 2004 of the upper cabinet body 2 through the connecting pipes 401, the air circulation can be carried out on the empty slots 2004 of each cabinet body 2 in a mode that the air pump 201 blows the gas from the vent 30101 to the surfaces of the arc protrusions 2001 through the connecting pipes 20101, and the temperature of the empty slots 2004 is reduced, so that the problem that heat between the cabinet bodies is difficult to dissipate due to assembly of each cabinet body 2 is avoided.

It should be noted that, when the ambient temperature around each cabinet 2 is too high, the cooling effect of the circulating air is reduced due to the limited air flow range, at this time, part of the air passing through the empty groove 2004 can be ejected from the air nozzle 402 through the first ventilation groove 2003 and the air nozzle 402, and the air ejected from the air nozzle 402 accelerates the air flow around each cabinet 2, so that the range of the circulating air can be further increased and the efficiency can be increased.

The electric sliding rail 101 is also included; the base 1 is provided with two electric sliding rails 101 which are symmetrically distributed in front-back mode, each electric sliding rail 101 is connected with a sliding block in a sliding mode, and the two sliding blocks are fixedly connected with the front side and the rear side of the supporting hollow bottom plate 102 respectively.

The invention works as follows:

When the ambient temperature around the bottom of the bottom cabinet 2 is too high, the temperature of the air entering the empty groove 2004 will also rise, which results in a decrease in the cooling efficiency between the assembled cabinets 2, at this time, the fan inside the ventilation system 103 can convey part of the cooling air stored inside due to the cool air from the telescopic air pipe 104 to the supporting hollow bottom plate 102, and expand the air bag 10201 and contact with the arc-shaped groove 2002, the cooling air can cool the surface of the air bag 10201, and the air passing through the gap between the air bag 10201 and the arc-shaped groove 2002 will contact the surface of the air bag 10201 to cool the air entering the empty groove 2004, and no moisture will permeate into the ventilation system 103 because of no direct contact with the moist air inside the ventilation system 103. It should be noted that, the base 1 is provided with two electric sliding rails 101 which are symmetrically distributed in front and back, and each electric sliding rail 101 is slidably connected with a sliding block, and the two sliding blocks are fixedly connected with the front side and the rear side of the supporting hollow bottom plate 102 respectively, and can be controlled to move up and down by controlling the sliding blocks on the electric sliding rails 101 and drive the supporting hollow bottom plate 102, the cabinet body 2 and the connected parts to move, so that the bottom cabinet body 2 is lifted, manual carrying is facilitated, and meanwhile, a drain outlet 10301 can be blocked, and dust entering during stop work is avoided.
