Working principle:
when a miner needs to carry the power distribution device, firstly, the extension rod 95 is driven by the pull ring 11, the extension rod 95 drives the sliding block 94 to slide in the second groove 92 and starts to extrude the second spring 93, at this time, the arc clamping block 96 at one end of the extension rod 95 is separated from the inner wall of the first clamping groove 97, at this time, the pull rod 4 loses restriction, only one hand is needed to hold the box body 1, the annular handle 12 is held by the other hand to lift upwards, at this time, the extrusion plate 85 at the bottom end of the pull rod 4 slides upwards along the first groove 84, along with the continuous upward movement of the extrusion plate 85, the pressure in the first groove 84 is increased, and the air pressure is conveyed to the inside of the folding air bag 7 through the guide pipe 86, along with the continuous increase of the pressure, the folding air bag 7 continuously expands, so that the two first springs 83 are extruded simultaneously by the sliding plate 82, and when the second clamping groove 98 and the arc clamping block 96 on the pull rod 4 are clamped, the folding air bag 7 expands to maximally to block the ventilation groove 10 in the cavity 3, and the inside of the box body 1 forms a relatively airtight space.
Meanwhile, due to the upward movement of the pull rod 4, the first rack 164 on the pull rod 4 moves together and drives the gear 163 to rotate, the second rack 165 moves downward under the cooperation of the gear 163 and drives the guide rod 166 to move downward, when the second clamping groove 98 on the pull rod 4 is clamped with the arc-shaped clamping block 96, the guide rod 166 drives the bottom plate 167 to extend out of the bracket 14, so that the pulley 168 moves to the lowest end, and at the moment, the whole power distribution device is convenient to move. At this time, the miners can take the box body 1 to take the monkey car to reach the appointed position.
When the power distribution device is required to be used, the pull ring 11 is pulled to enable the arc-shaped clamping blocks 96 not to be clamped with the second clamping grooves 98, the pull rod 4 is pushed reversely to enable the pull rod 4 to drive the extrusion plate 85 to reset, at the moment, the pressure in the first groove 84 is gradually reduced, the pressure in the folding air bag 7 is also continuously reduced, at the moment, the pressure born by the two first springs 83 is reduced, when the pressure is smaller than the elastic force of the two first springs 83, the folding air bag 7 is extruded by the two first springs 83 through the sliding plate 82, the ventilation groove 10 is communicated, and finally the arc-shaped clamping blocks 96 are clamped with the first clamping grooves 97. At the same time, the guide rods 166 drive the base plate 167 back into the rack 14 for placing the electrical distribution device in a fixed position.
