Referring to fig. 6 to 7, two ends of the third rotating rod 503 are limited to slide inside the first rotating rod 501 and the second rotating rod 502, so that the third rotating rod 503 can only slide but cannot rotate along the inside of the first rotating rod 501 and the second rotating rod 502, thereby transmitting the rotating force.
In a preferred embodiment: the third rotating rod 503 can only slide but cannot rotate along the inside of the first rotating rod 501 and the second rotating rod 502, so that when the first rotating rod 501 rotates, the third rotating rod 503 can be driven to rotate, and therefore force is transmitted to the second rotating rod 502, and normal rotation operation of the second rotating rod is ensured.
Working principle: in the rainy day environment, as rainwater continuously falls into the water storage tank 401 positioned at the top of the power distribution cabinet 2, the floating blocks 402 positioned in the water storage tank are influenced by buoyancy of the floating blocks, and synchronously move upwards along with the rising of the liquid level, the floating blocks 402 moving upwards pull the push rod 403, so that the push rod 403 drives the shielding plate 404 to vertically move upwards, the shielding plate 404 completely shields the heat dissipation groove 8 from the inside of the power distribution cabinet 2, and rainwater is prevented from entering the inside of the power distribution cabinet 2 along the heat dissipation groove 8; along with the continuous rising of the liquid level in the water storage tank 401, the curved extrusion block 405 at the bottom of the push rod 403 is driven to continuously move upwards until the curved extrusion block 405 contacts the bottoms of the two curved sleeving blocks 504, and the two curved sleeving blocks 504 are extruded under the pulling of the buoyancy of the floating block 402, so that the sleeving second rotating rod 502 and the third rotating rod 503 synchronously extend outwards, the gear 505 at the outer side of the second rotating rod 502 is meshed with the rack 506, the rack 506 is driven to move upwards through the rotation of the gear 505, the waterproof outer cylinder 6 at the inner side of the base 1 is driven to rise until the waterproof outer cylinder is completely sleeved at the outer side of the bottom of the power distribution cabinet 2 for protection, after rain stop, the liquid level in the water storage tank 401 continuously falls, at the moment, the push rod 403 drives the shielding plate 404 to move downwards synchronously with the curved extrusion block 405, so that the shielded heat dissipation groove 8 is exposed again, and meanwhile the second rotating rod 502 losing extrusion force drives the gear 505 to move in a reset mode, the gear 505 is disengaged from the rack 506, the rack 506 which is not controlled by the rotating force falls, the waterproof outer cylinder 6 positioned at the bottom of the rack falls back to the inside of the base 1 again by virtue of self gravity to be hidden, the power distribution cabinet does not need to carry out lifting treatment on the power distribution cabinet, the waterproof performance is obviously improved, the subsequent maintenance work is not influenced, and the water draining speed of the water storage tank 401 of the power distribution cabinet 2 can be correspondingly regulated according to actual requirements, the regulation mode can be realized by changing the size of a water draining port, so that the water draining port can be ensured to remain for enough time for maintenance by workers after heavy rain, the phenomenon that the accumulated water generated after heavy rain is still positioned at the bottom of the power distribution cabinet 2, but the waterproof outer cylinder 6 falls down and returns to be incapable of playing a protection effect is avoided, and in the maintenance process, if the workers still find that the water level after the heavy rain is higher, can seal the water outlet of the water storage tank 401 and avoid the influence of the descending of the waterproof outer cylinder 6 on the tightness of the bottom of the power distribution cabinet 2.
The foregoing description is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, who is within the scope of the present application, should make equivalent substitutions or modifications according to the technical solution of the present application and the inventive concept thereof, and should be covered by the scope of the present application.
