[0023] Working principle: when the temperature of the power distribution cabinet is too high, the temperature detector 6 will detect the temperature of the power distribution cabinet, and the electric signal will be transmitted to the alarm lamp 3 to make it alarm, so as to attract the maintenance personnel to detect and prevent the temperature from being too high due to short circuit fire in the power distribution cabinet. When the electric signal is transmitted to the alarm lamp 3, it will be transmitted to the fan assembly 5 and started, so that the hot air in the power distribution cabinet can be blown out, so that the internal temperature of the power distribution cabinet can be automatically cooled down, so as to avoid the continuous rise of the temperature of the power distribution cabinet and cause damage to the internal electronic components. At the same time, when the filter plate 7 in the power distribution cabinet is blocked, the motor 8 starts to drive the threaded rod 9 to rotate. In the process of rotating the threaded rod 9, the screw groove on the surface of the threaded rod 9 will be in contact with the slider inside the brush plate 10, so as to move the brush plate 10 along the rotating direction of the threaded rod 9, so as to hang the dust on the surface of the filter plate 7, so as to improve the ventilation efficiency of the power distribution cabinet. The movement of the brush plate 10 drives the movement of the connecting block 12, the movement of the connecting block 12 drives the movement of the reciprocating screw rod 13, the movement of the reciprocating screw rod 13 drives the movement of the transmission wheel 14. In the process of moving, the transmission wheel 14 will be in contact with the ventilation window 4 and generate friction to make the transmission wheel 14 rotate. The rotation of the transmission wheel 14 drives the reciprocating screw rod 13 to rotate. The rotation of the reciprocating screw rod 13 will make the slider inside the cleaning plate 17 in contact with the screw on the surface of the reciprocating screw rod 13, so that the cleaning plate 17 can move back and forth, so as to further improve the dust cleaning effect of the filter plate 7, so as to quickly reduce the temperature in the power distribution cabinet.

[0024] When the temperature of the power distribution cabinet is too high, the motor 8 will prolong the clockwise rotation time of the threaded rod 9, so that the connecting block 12 can move to a position that cannot be moved when moving downward, at this time the connecting block 12 drives the sliding push plate 154 to continue to move downward, so that the sliding push plate 154 and the stressed plate 152 are in contact with each other, and the stressed plate 152 is pushed to move downward, the stressed plate 152 moves downward to drive the sliding rod one 151 to move downward, the sliding rod one 151 moves downward to drive the inclined plate one 153 to move downward, so that the limit of the cabinet door 2 can be contacted, so that the cabinet door 2 can be easily opened, avoiding the case that when the power distribution cabinet encounters an emergency fire inside, the temperature of the cabinet door 2 is too high to cause the fire extinguishing personnel to have difficulty in opening the cabinet door 2, thereby affecting the fire extinguishing progress of the power distribution cabinet and affecting the rescue of the fire situation. At the same time, the sliding push plate 154 moves downward to contact the baffle 1510 and push the baffle 1510 to move downward, the baffle 1510 moves downward to drive the moving rod 156 to move downward, the moving rod 156 moves downward to make the moving rod 156 leave the inside of the push block 159 and thereby release the limit of the elastic rod 158, so that the elastic rod 158 moves forward by the spring and drives the push block 159 to move, thereby enabling the push block 159 to impact the cabinet door 2 and push the cabinet door 2 away, so as to further help the fire extinguishing personnel to extinguish the fire inside the power distribution cabinet, avoiding the further expansion of the fire. When the cabinet door 2 is normally closed, the cabinet door 2 will generate a pressing force on the inclined plate one 153 to make the sliding rod one 151 move downward, the sliding rod one 151 moves downward to drive the stressed plate 152 to move downward, thereby being able to quickly limit the cabinet door 2, and being able to automatically lock the cabinet door 2, so as to improve the working efficiency of the power distribution cabinet during use.

When the ventilation window 4 is cleaned, the downward movement of the sliding push plate 154 drives the straight plate 162 to move downward, which contacts the movable door 163 and pushes it to flip downward, so that the collecting box 161 can be opened, thereby collecting the scraped dust. After the dust falls into the collecting box 161, the upward movement of the straight plate 162 no longer presses the movable door 163, so that the movable door 163 rotates through the torsion spring, thereby sealing the dust falling into the collecting box 161, avoiding the dust being blown into the electronic components in the power distribution cabinet, thereby easily causing the electronic short circuit in the power distribution cabinet. The front part of the sliding push plate 154 is fixedly connected to a second inclined plate 164, the inner wall of the second inclined plate 164 is slidingly connected to a second sliding rod 165 through a spring, the left side of the second sliding rod 165 is fixedly connected to a knocking block 166, the right side of the filter plate 7 is fixedly connected to a protruding block 167, the right side of the straight plate 162 is in contact with the left side of the movable door 163, and the right side of the filter plate 7 is in contact with the knocking block 166. At the same time, the movement of the sliding push plate 154 drives the movement of the second inclined plate 164, the movement of the second inclined plate 164 drives the movement of the second sliding rod 165, the movement of the second sliding rod 165 drives the movement of the knocking block 166, and the movement of the knocking block 166 contacts the protruding block 167, thereby making the knocking block 166 be pressed by the protruding block 167, so that the knocking block 166 moves to the right and stretches the spring. After the knocking block 166 passes the protruding block 167, it is no longer pressed by the protruding block 167, so that the knocking block 166 is reset through the elastic force of the spring, which can make the knocking block 166 knock the surface of the filter plate 7, thereby making the surface of the filter plate 7 vibrate, thereby vibrating the dust remaining in the holes in the filter plate 7, improving the ventilation effect of the filter plate 7 and the service life of the filter plate 7.

[0026] Working principle: when the ventilation window 4 is cleaned, the sliding push plate 154 moves downward to drive the straight plate 162 to move downward, the straight plate 162 moves downward to contact the movable door 163 and push the movable door 163 to overturn downward, so that the collecting box 161 can be opened, so that the dust scraped off can be collected, and after the dust falls into the inside of the collecting box 161, the straight plate 162 moves upward and no longer extrudes the movable door 163, so that the movable door 163 is rotated by the torsional spring, thereby the dust falling into the inside of the collecting box 161 can be closed, avoiding that the dust is blown to the electronic elements in the power distribution cabinet by the wind, thereby the problem that the electronic short circuit in the power distribution cabinet is easily caused is avoided, meanwhile, the sliding push plate 154 moves to drive the inclined plate two 164 to move, the inclined plate two 164 moves to drive the sliding rod two 165 to move, the sliding rod two 165 moves to drive the knocking block 166 to move, the knocking block 166 moves to contact the protrusion 167, thereby the knocking block 166 is extruded by the protrusion 167, so that the knocking block 166 moves right and stretches the spring, after the knocking block 166 passes the protrusion 167, the knocking block 166 is no longer extruded by the protrusion 167, so that the knocking block 166 is reset by the elastic force of the spring, so that the knocking block 166 knocks the surface of the filter plate 7, thereby the surface of the filter plate 7 is vibrated, thereby the dust remaining in the hole in the filter plate 7 can be vibrated out, the ventilation effect of the filter plate 7 and the service life of the filter plate 7 are improved.
