Because the cabinet body 1 is set up in the open air for filter screen or louvre are very easily blockked up by the dust, perhaps dust gets into equipment, cause ageing and the damage of equipment, block up the filter screen, very easily reduce the inside whole radiating efficiency of the cabinet body 1.

The rotation of the second rotating shaft 21 can be driven by different driving sources, optionally a motor, and can be controlled by a program to perform a certain period of rotation within a certain time.

When second pivot 21 rotated, make incomplete gear 23 can rotate in step, because the intermittent type meshing of incomplete gear 23 and two racks, make installation piece 12 can remove about, thereby drive mounting box 11 and brush hair 13 and can remove about, make brush hair 13 can carry out the brush of certain degree to the filter screen then, prevent that the dust from blockking up the filter screen, influence the inside holistic radiating efficiency of the cabinet body 1, carried out the cleanness of certain degree to the filter screen simultaneously.

Further, the top fixedly connected with roller seat 22 of second pivot 21, the outer wall of roller seat 22 is convoluteed and is had two 26 ropes, the one end of two 26 ropes and the outer wall fixed connection of roller seat 22, the other end of two 26 ropes passes the outer wall fixed connection of fixed pulley 25 with backup pad 4, outwards remove when backup pad 4 can draw roller seat 22 through two 26 ropes and unreel, make second pivot 21 rotate, the outer wall fixed connection that second pivot 21 is close to the bottom has coil spring 24, the other end of coil spring 24 and the interior bottom fixed connection of cabinet body 1.

When backup pad 4 is when outwards moving, through rope two 26, the cooperation of fixed pulley 25 and roller seat 22, make roller seat 22 can unreel, thereby make second pivot 21 can rotate, thereby can drive removal about installation piece 12 and mounting box 11 carry out, roller seat 22 when unreeling, can make coil spring 24 can be twisted round, thereby save elastic potential energy, when backup pad 4 relaxs, the elastic potential energy that coil spring 24 was saved can drive second pivot 21 and rotate, thereby can make roller seat 22 roll again and reset, and installation piece 12 and mounting box 11 still can take place left and right sides reciprocating motion, thereby clean the dust to filter screen or louvre once more, and can also assist the reseing of backup pad 4.

Further, the outer wall of the mounting box 11, which is close to the brush bristles 13, is a rectangular array and is penetrated by a plurality of air outlets 20, the mounting box 11 is communicated with the outside through the air outlets 20, the air outlets 20 and the mounting box 11 are alternately distributed, and the air transmission mechanism is provided for providing air flow inside the mounting box 11.

For 11 inside air currents that provide of mounting box through air conveying mechanism, make mounting box 11 when clearing up the dust to filter screen or louvre, can blow off cabinet body 1 with being in not hard up dust, equally, can also clear up the dust between a plurality of brush hairs 13.

Further, the gas transmission mechanism includes piston box 10, piston box 10 fixed mounting is in the interior bottom of the cabinet body 1, the inner wall sliding connection of piston box 10 has piston plate 17, piston box 10 is close to the outer wall of cabinet door 2 and has run through piston rod 16, and piston rod 16 and the sliding connection that runs through, piston rod 16 penetrates the inside tip of piston box 10 and the outer wall fixed connection of piston plate 17, piston rod 16 exposes outside tip and passes through the edge bottom fixed connection of connecting rod and backup pad 4, the outer wall that piston box 10 is close to mounting block 12 runs through and has seted up the through-hole, the inside of through-hole is provided with the inside check valve of one-way inflow piston box 10, the outer wall intercommunication that piston box 10 is close to mounting block 12 has hose 18, the other end of hose 18 and the inside intercommunication of mounting block 11, the inside check valve of one-way inflow mounting block 11 that sets up of hose 18.

Due to the sliding connection of the piston plate 17 inside the piston box 10, the inside of the piston box 10 is divided into two chambers, one of which is close to the mounting block 12, and the chamber close to the mounting block 12 is referred to as a main chamber.

When backup pad 4 is when outwards moving, drive piston rod 16 outwards and remove through the connecting rod, it removes to the direction of cabinet door 2 to drive piston plate 17 in step, thereby make main cavity accessible through-hole breathe in, make the certain volume of main cavity's inside air gathering, on the contrary, when backup pad 4 is close to when reseing to installation piece 12, can drive piston rod 16 and piston plate 17 synchronous motion, make a large amount of air can be through the inside of hose 18 transport to mounting box 11 this moment, then the air is quick flows through 20 pressure releases of venthole, thereby accomplish the processing to the dust.

Further, the outer wall cover of the piston rod 16 inside the piston box 10 is provided with a return spring, and by arranging the return spring, the elastic potential energy accumulated in the front of the return spring can assist in the resetting of the support plate 4 and the piston plate 17, and meanwhile, the movement of the support plate 4 and the piston plate 17 can be accelerated, so that the conveying speed of gas is higher, the pressure inside the mounting box 11 is higher, and the blown wind power is stronger.

Further, backup pad 4 passes through spout slider mechanism sliding connection at the inner wall of the cabinet body 1, and the contact surface of spout slider mechanism is provided with the damping design, and the damping design can be for increasing the coarse degree of spout slider driving surface, through the cooperation of damping design and communication equipment self weight for the outside pull-out speed of backup pad 4 reduces, prevents not using for a long time, leads to suddenly applied external force to probably cause rocking of communication equipment.

Through the cooperation of above-mentioned isotructure, can make communications facilities remove to the outside, make things convenient for the staff debugging, can also make communications facilities can rotate certain angle for communications facilities's side or the back can expose under staff's field of vision, thereby make things convenient for the staff to inspect and maintain it.

The working principle is as follows: when the outdoor communication cabinet convenient to overhaul is used, the supporting plate 4 is pulled to move outwards, and the pulling distance is less than the preset value, so that the communication equipment on the top of the disc 5 can synchronously move outwards, thereby facilitating the operations of debugging and the like on the front of the equipment of a worker, when the side and the back of the communication equipment need to be maintained and disassembled, the supporting plate 4 is continuously pulled to move outwards to the preset value, the gear 9 is meshed with the toothed plate 7, as the support plate 4 continues to move outwards, the gear wheel 9 will rotate, here clockwise, because the gear 9 and the disc 5 are coaxially fixed, the communication equipment on the top of the disc 5 can rotate a certain angle, the side or the back of the communication equipment can be exposed under the visual field of workers, so that the communication equipment is convenient for the workers to check and maintain.

The standard parts used in the present embodiment may be purchased directly from the market, and the non-standard structural components described in the specification and drawings may be obtained by processing without any doubt according to the common general knowledge in the art, and the connection manner of the respective parts is by the conventional means developed in the art, and the machines, parts and equipment are of the conventional type in the art, so that the detailed description thereof is omitted.
