When rainy weather occurs, rainwater enters the mounting frame 31 from the second air holes 311 on the upper side wall of the mounting frame 31 and enables the water-absorbing expansion material 34 to absorb water and expand rapidly, so that the water-absorbing expansion material 34 can rapidly push the sliding member 32 to slide in the direction close to the second elastic member 33, in the process, the sliding member 32 can drive the first driving arm 35 and the driving rod 351 to synchronously move, and then the driving rod 351 pushes the shielding plate 13 to slide in the direction close to the fourth driving arm 173 through the first groove 1331, so that the first through holes 130 and the first air holes 12 are staggered with each other, the effect of preventing water from entering the inside of the power distribution cabinet body 10 is achieved, meanwhile, one ends, away from the corresponding shaft rods 17, of the third driving arm 172 and the fourth driving arm 173 respectively slide into the corresponding arc-shaped portions 1312, and at the moment, the third driving arm 172 can drive the corresponding shaft rod 17 to rotate and the second driving arm 171 to rotate upwards so that the blocking member 24 blocks the second through holes 151, and the fourth driving arm 173 are similar.
With the progressive increase of the rainwater in the water accumulation tank 14, the floating piece 222 drives the first slide bar 22 and the mounting cylinder 21 to move upwards to a certain height, when the raining is stopped, with the progressive turning of weather, the water in the water accumulation tank 14 is gradually evaporated, in the process, the height of the floating piece 222 in the water accumulation tank 14 is gradually reduced, so that the first slide bar 22 moves downwards, however, under the action of the inclined part 213, the first slide bar 22 presses the sphere 251 on the inclined part 213, so that the first slide bar 22 does not move downwards relative to the mounting cylinder 21, but the mounting cylinder 21 moves downwards along with the first slide bar 22 along the annular cavity of the annular piece 16, at the same time, the blocking piece 24 opens the second through hole 151 downwards, the rainwater in the water accumulation tank 14 flows downwards from the annular cavity of the annular piece 16 through the second through hole 151, the lower end of the supporting piece 211 is in contact with the upper end of the supporting plate 15, with the downward rainwater flowing out, the impeller 23 is driven to rotate by the rainwater, so that the driving member 231 rotates to contact the stopper 27, and the stopper 27 is separated from the abutting contact of the engaging plate 252, then under the action of the pulling force of the first elastic member 26, the engaging plate 252 is pulled up, so that the second slide rod 25 slides up along the length extension direction of the mounting cylinder 21, the ball 251 slides up out of the abutting contact with the first slide rod 22 and the inclined portion 213, so that the first slide rod 22 slides down along the length extension direction of the mounting cylinder 21, in the process, the rainwater is continuously discharged downwards from the second through hole 151, when the first slide rod 22 slides down to the abutting contact with the transition member 253, the first slide rod 22 continuously presses down the transition member 253 under the action of gravity and synchronously moves down the engaging plate 252, so that the first elastic member 26 is stretched, and the stopper 27 abuts against the upper end face of the engaging plate 252 under the action of the torsion spring, at this time, the rainwater in the water storage tank 14 is completely discharged.
In this process, since the blocking piece 24 opens the second through hole 151 downward, the blocking piece 24 drives the second driving arm 171 downward to rotate, so the second driving arm 171 drives the corresponding shaft 17 to rotate and makes the end of the third driving arm 172 away from the shaft 17 rotate upward into the vertical portion 1311, so the third driving arm 172 can slide the shielding plate 13 in the opposite direction to make the first through hole 130 at a position corresponding to the first ventilation hole 12, so as to facilitate heat dissipation inside the power distribution cabinet body 10.
In the process, the end of the third driving arm 172 away from the shaft 17 slides upwards from the arc portion 1312 into the vertical portion 1311, the third driving arm 172 can push the shutter 13 to approach the fourth driving arm 173 for a distance, so that the driving rod 351 can sequentially pass through the transition slope, the second slot portion 1332 and the transition plate 134 and then enter the fourth slot portion 1334 with the aid of the third elastic member 321, and the sliding member 32 does not move in the process; after the water-swelling material 34 naturally dries and recovers the original volume, under the action of the second elastic member 33, the sliding member 32 is pushed by the second elastic member 33 and moves away from the second elastic member 33, in this process, the sliding member 32 drives the driving rod 351 to move, the driving rod 351 enters the first slot 1331 through the third slot 1333, and in this process, the driving rod 351 does not drive the shutter 13 to move.
That is, when the water-absorbing expansion material 34 absorbs water and expands rapidly, the sliding member 32 can be driven to move so as to drive the shielding plate 13 to shield the first air holes 12, and the blocking member 24 can be driven to block the second through holes 151; however, when the weather is changed, the blocking piece 24 opens the second through hole 151 and drives the shielding plate 13 to separate from the shielding of the first air hole 12, however, the blocking piece 24 cannot drive the sliding piece 32 to move, and after the water-swelling material 34 naturally dries and recovers the original volume, the movement of the sliding piece 32 will not affect the shielding plate 13 to separate from the shielding of the first air hole 12.
