Detailed Description

Referring to fig. 3, 5 and 6, there is shown a schematic diagram of the present invention, in which the fan 11 is driven to rotate to cool the interior of the device, and the filter screen 11 staying in the air inlet hole of the top plate 2 is used to block dust, sand, stone and other substances, so as to prevent the substances from entering the device and interfering the power distribution device in operation, and when the substances on the filter screen 11 are accumulated to a certain extent, the filter screen 11 is automatically replaced for the convenience of the worker, further,

the fan 10 on the top plate 2 is driven by a motor to rotate on the top plate 2, air outside the device is pumped into the device by the rotating fan 10, when the air outside the device flows into the device, substances such as dust, sand and stone are brought in, and the substances fall into the device to affect the heat dissipation effect of the device, the sliding block 4 on the sliding way 3 is moved, the sliding block 4 drives the filter screen 11 to move to the air inlet hole of the top plate 2 to block the dust and the sand carried in the air flowing from the air inlet hole, a tension spring is arranged between the sliding block 4 and the sliding way 3, when the sliding block 4 moves, the tension spring is stretched to generate reverse tension to pull the sliding block 4 to reversely move back to the initial position, in order to fix the sliding block 4, the limiting rod 6 rotating on the fixing plate 5 needs to move, the limiting rod 6 is in contact with the sliding block 4, so as to achieve the purpose of limiting the movement of the sliding block 4 by the limiting rod 6, in order to ensure that the limiting rod 6 can continuously block the sliding block 4, the limiting rod 6 needs to be controlled to keep vertical, the control block 7 which is connected with the limiting rod 6 in a sliding mode needs to be controlled to slide upwards, the control panel 9 limits the connecting rod 8 to move upwards, the position of the control block 7 is fixed, the fixing rod 6 cannot be pushed by the sliding block 4 to rotate, and the limiting rod 6 can be used for fixing the sliding block 4.

After 11 surfaces of filter screen are blocked, promote the gliding of control panel 9, drive connecting rod 8 downstream through control panel 9, make connecting rod 8 drive control block 7 slide on gag lever post 6, thereby it is rotatory to drive gag lever post 6 through control block 7, make gag lever post 6 can't continue to block slider 4, the extension spring of connecting on slider 4 loses the constraint, make the extension spring can drive slider 4 and remove back initial position, drive filter screen 11 and remove, make filter screen 11 no longer block the inlet port on roof 2, the staff of being convenient for changes.

The gag lever post 6 is provided with two, can be better through two gag lever posts 6 block slider 4, make the pulling force that the both ends of slider 4 received offset by two gag lever posts 6 to ensure that slider 4 can not skew because of the uneven emergence of atress, thereby harm slider 4.

The extension spring that sets up between fixed plate 5 and the control panel 9 can prevent that control panel 9 from receiving self gravity to influence the gliding to lead to slider 4 to be changed in advance when filter screen 11 does not reach the assigned state, make filter screen 11 can normally maintain the normal operating of device.

Referring to fig. 1, 2, 5, 6 and 7, it is shown that according to the present invention, the box body 1 and the top plate 2 cooperate to protect the power distribution device, so as to prevent the power distribution device from being damaged by wind, rain and the like, and the fan 10 continues to rotate after the surface of the filter screen 11 is blocked, so that the air pressure in the box body 1 is lower than the air pressure outside the box body 1, thereby driving the control board 9 to slide downwards to drive the slider 4 to move, so that the filter screen 11 cannot block the top plate 2, further,

exhaust ducts are respectively arranged at two ends of the box body 1, air outside the box body 1 is pumped into the box body 1 through the rotation of the fan 10 on the top plate 2, the air flows in the box body 1 after entering the box body 1 and flows out from the exhaust ducts at the two ends of the box body 1, the air flows out from the exhaust ducts and simultaneously conveys heat generated by the operation of the power distribution device, so that the power distribution device in the box body 1 can be kept at a certain temperature, the work efficiency of the power distribution device cannot be influenced due to overhigh temperature, when the fan 10 rotates, substances such as dust and the like are gradually accumulated on the surface of the filter screen 11, the filter screen 11 is gradually blocked to block an air supply hole on the top plate 2, the air outside the box body 1 cannot flow into the box body 1 through the top plate 2, the air inside the box body 1 flows out from exhaust passages at the two ends of the box body 1 through the operation of the fan 10, and the air pressure inside the box body 1 is smaller than the air pressure outside the box body 1, promote control panel 9 downstream through the pressure difference, make the extension of the extension spring on the control panel 9 to make the gag lever post 6 on the 5 both ends of fixed plate remove, lead to two gag lever posts 6 can not restrict slider 4, make slider 4 receive the influence of extension spring and remove, drive filter screen 11 and remove, make filter screen 11 can not be to the blast hole shutoff on roof 2, fan 10 rotation can continue to cool down to the distribution device in the box 1.

Meanwhile, the movable filter screen 11 can be immediately found when a worker detects the movable filter screen, and the movable filter screen 11 is replaced in time, so that the influence on the operation of the power distribution device is reduced.

Door shelves 12 rotate to be connected on box 1, carry out the shutoff through rotating door shelves 12 to box 1 to make distribution device can not receive the harm of dust and grit, the possibility that the reduction winged insect gnaw the distribution device simultaneously by a wide margin.
