In the invention, when the equipment elements in the main cabinet work, a part of the equipment elements can generate more heat, and if the heat dissipation function is not available, the heat can be accumulated in the main cabinet, thereby influencing the service life and the functional stability of the equipment elements. Therefore, when the equipment elements in the main cabinet work, the air inlet fan and the air outlet fan also work, and the external air sequentially passes through the side air inlet cover, the air inlet (air inlet filter screen), the air inlet fan, the interior of the main cabinet, the air outlet fan, the air outlet (air outlet filter screen) and the side outlet cover and is finally discharged, so that the heat in the main cabinet can be continuously taken away, and the heat dissipation airflow is formed to realize heat dissipation.

In the invention, the working state of the reciprocating brush structure can be intelligently and automatically switched, and the specific principle is explained as follows.

When air passes through the air inlet filter screen, a part of dust carried by the air can be attached to the air inlet filter screen, and after a long time, the amount of the dust attached to the air inlet filter screen can become very large (equivalent to that the air inlet aperture becomes very small), so that the heat dissipation effect of heat dissipation airflow can be obviously influenced. When the reciprocating brush structure normally works, gas discharged from the air outlet end of the air inlet fan is enough to blow the air bearing ring plate and enable the air bearing ring plate to be kept at the position where the limiting block contacts the inner limiting ring, at the moment, the driving conductive contact strip contacts the driving outer contact body and is separated from the driving inner contact body, and the reciprocating brush structure does not work. The dust quantity attached to the air inlet filter screen gradually increases, and at the beginning of a certain time, due to the deficiency of the air inlet caliber, the gas discharged from the air outlet end of the air inlet fan can no longer ensure that the air bearing ring plate is in the position of the limit block contacting the inner limit ring (in other words, the air inlet caliber is gradually reduced before the air inlet end is in the state of the limit block contacting the inner limit ring), then the dust quantity attached to the air inlet filter screen continuously increases, the air inlet caliber is continuously reduced, the air bearing ring plate reaches the position of the air bearing ring plate contacting the outer limit ring, at the moment, the driving conductive contact strip contacts the driving outer contact, the driving conductive contact strip contacts the driving inner contact, the driver, the driving outer contact, the driving conductive contact strip and the driving inner contact are sequentially connected in series, the driver works to drive the disc shaft and the disc to rotate, and the disc drives the vertical rod through the reciprocating rod, Reciprocating motion about the brush, along with the upper and lower reciprocating motion of brush, the filter screen that admits air is gone up adnexed dust and is brushed down (the brush moves up and down at every turn, can both brush away some attached to the filter screen that admits air) down again to make "the bore" grow of admitting air, a certain moment, the ring board that holds the wind can reach the position of spacing ring in the stopper contact again, at this moment, the electrically conductive touch strip of drive contact drive external contact body, the electrically conductive touch strip of drive is with the separation of the interior touch body of drive, thereby reciprocal brush structure automatic stop work.

In this scheme, in case the wind-bearing ring board reaches the position of "wind-bearing ring board contacts outer spacing ring", drive circuit switches on, powerful fan (pumping of powerful fan, the gas transmission ability is stronger than the air inlet fan far away and the fan of giving vent to anger) has just been started, at this moment, the air current of the end of giving vent to anger of powerful fan can be blown through two horizontal blowing mouths towards the filter screen that admits air, come the clearance with "powerful air current and attach to the dust on the filter screen that admits air (the air inlet is in between two horizontal blowing mouths, so horizontal blowing mouth is not blowing towards the filter screen that admits air, but the side-blown, such clearance effect is stronger), the action of the reciprocating brush structure of reunion, can obviously promote cleaning efficiency and effect.

In addition, when the powerful fan is started, the blockage of the air inlet filter screen is serious, and the heat dissipation capacity provided by the original heat dissipation structures such as the air inlet fan and the air outlet fan is also obviously reduced, so that the powerful fan also has the effect of supplementing and strengthening the heat dissipation capacity in a short time. The air inlet outer side pipe and the air inlet inner side pipe are obviously arranged for heat dissipation inside the main cabinet, the air inlet auxiliary pipe is used for supplementing the air inlet caliber of the powerful fan, the air transmission capacity of the powerful fan is high, so that a larger air inlet caliber is needed, and the air outlet end of the powerful fan is not arranged in the main cabinet, so that even if some dust is sucked from the air inlet auxiliary pipe, the cleaning of the air inlet filter screen by the powerful fan and the driving of the reciprocating brush structure cannot be influenced.

The foregoing describes how the reciprocating brush structure is activated and automatically deactivated. However, there are still some problems: it is known from the foregoing that, when the intake filter screen is clogged to a certain extent, the air bearing ring plate reaches the position where the air bearing ring plate contacts the outer retainer ring, so that the reciprocating brush structure starts to operate. After the brush moves up and down to brush several air inlet filter screens, although the air inlet filter screens are not completely cleaned, certain blockage cleaning is realized, at the moment, the air bearing ring plate reaches the position of the limit block contacting the inner limit ring again (at the moment, the brush stops working), which causes the condition that the brush (a reciprocating brush structure) stops working after the air inlet filter screens are cleaned by the brush for one or two times, and then, because the air inlet filter screens are cleaned slightly and still attached with a large amount of dust, as the invention continues working for too long, the invention can trigger the reciprocating brush structure to work again, which is equivalent to that the reciprocating brush structure is started frequently and many times, and the air inlet filter screens are in a critical state for a long time (the critical state is that a large amount of dust is attached to the air inlet filter screens, but the air inlet caliber is not too small yet, in this state, the air intake efficiency can be regarded as "qualified", but it is far from reaching "excellent", that is, under the premise that the power of the air intake fan and the air outlet fan is not changed, the ventilation and heat dissipation effects are barely qualified, but not very good).

Therefore, in this embodiment, a more optimized scheme is provided: once the reciprocating brush structure is started, the air inlet filter screen is cleaned as far as possible, and then the reciprocating brush structure stops working and the heat dissipation structure returns to a normal working state.

Specifically, as is known from the foregoing, when the air inlet filter screen is blocked to a certain extent, at a certain moment, the air bearing ring plate reaches the position where the air bearing ring plate contacts the outer limit ring, so that the powerful fan and the reciprocating brush structure start to work, meanwhile, because the first conductive contact strip is separated from the first outer contact body, the first conductive contact strip contacts the first inner contact body, the heat dissipation circuit is broken, the air inlet fan is stopped, the air outlet fan is stopped, and because the oil return electromagnetic valve is powered off and normally open, the oil return electromagnetic valve is opened (at this time, the second conductive contact strip contacts the second upper contact body, the second conductive contact strip is separated from the second lower contact body), a part of hydraulic oil in the upper oil tank continuously flows into the lower oil tank through the oil return lower hole, the oil return pipe and the oil return side hole source, the liquid level in the lower oil tank rises, the floating body, the drainage auxiliary shaft and the lower bevel gear rise together until the lower bevel gear is meshed with the upper bevel gear, go up the liquid level in the oil tank then and continuously reduce (after lower bevel gear and last bevel gear meshing, the hydraulic oil that goes up in the oil tank still can continue to flow to the oil tank down in), the oil tank bottom is gone up to the come-up body contact, and the contact is established ties in proper order under the fan of giving vent to anger, oil return solenoid valve, the air inlet fan, the second, the electrically conductive touch strip of second and the second, and the radiating circuit switches on, and the air inlet fan, the fan of giving vent to anger restart this moment, and the oil return solenoid valve is got the electricity normal close.

Air inlet fan, when the fan of giving vent to anger just started, air inlet fan gives vent to anger near the end the air current still not strong enough, can't let the wind-bearing ring board be in the position of spacing ring in the "stopper contact", so drive circuit still switches on this moment, powerful fan is also working still, after a while, air inlet fan, the fan full power operation of giving vent to anger, the wind-bearing ring board reaches the position of spacing ring in the "stopper contact", this moment "the electrically conductive touch strip of drive contacts the drive external contact body, the electrically conductive touch strip of drive is separated with the interior contact body of drive, drive circuit opens circuit, powerful fan shuts down, reciprocal brush structure also stop work. Above-mentioned in-process, the hydraulic oil of going up in the oil tank is from beginning flowing out, and the process of oil tank bottom is gone up to the floating body contact, needs a period of time, and in this period of time, powerful fan, reciprocal brush structure continue to work to reciprocal brush structure can be with the dust clean up on the air inlet filter screen.

Before the connection, the air inlet fan and the air outlet fan operate in full power, the powerful fan is stopped, after the reciprocating brush structure stops working, because the lower bevel gear is meshed with the upper bevel gear at the moment, the air inlet fan drives the drainage impeller to rotate through the drainage main shaft, the upper bevel gear, the lower bevel gear and the drainage auxiliary shaft, the drainage impeller enables hydraulic oil below the drainage impeller to ascend, the hydraulic oil in the drainage main pipe returns to the upper oil tank through the oil conveying side hole, the oil conveying pipe and the oil conveying upper hole until the liquid level in the lower oil tank descends to the upper bevel gear and is separated from the lower bevel gear, the liquid level of the hydraulic oil in the upper oil tank is higher than the lower end of the floating limiting body at the moment, the upper floating body contacts the floating body limiting body again, the second conductive contact strip contacts the second upper contact body, and the second conductive contact strip is separated from the second lower contact body. The reason why the upper bevel gear is separated from the lower bevel gear is that the lower bevel gear, the drainage auxiliary shaft and the drainage impeller can continue to rotate for a moment due to inertia when the lower bevel gear just leaves the upper bevel gear, and therefore hydraulic oil in a certain amount of the lower oil tank can be sent to the upper oil tank through the oil conveying pipe. The upper bevel gear is "decoupled" from the lower bevel gear only when the lower bevel gear is moved away from the upper bevel gear and reaches a standstill.
