Thus, when the turbine 303 rotates, because the weight of the turbine 303 cannot be balanced, the centrifugal force generated when the turbine 303 rotates swings, so as to press the C-shaped frame 2 downward, when the C-shaped frame 2 is pressed downward, the L-shaped hook 601 fixedly connected with the C-shaped frame 2 moves downward along with the C-shaped frame, and at the same time, the sealing plate 403 is absorbed by the negative pressure generated by the turbine 303, so that the connecting plate 603 fixedly connected with the sealing plate 403 is pulled towards the L-shaped hook 601, so that the L-shaped hook 601 hooks the upper surface of the extrusion block 605, when the L-shaped hook 601 moves downward, the extrusion block 605 is pressed downward, at this time, the power storage spring 610 sleeved on the guide rod 604 is compressed, and the connecting rod 609 rotatably connected with the extrusion block rotates towards the direction away from the T-shaped push block 606, so as to push the L-shaped blocking rod 608 away from the T-shaped push block 606, when the L-shaped blocking rod 608 completely separates from the lower surface of the T-shaped push block 606, the T-shaped push block 606 moves downwards under the thrust of the power storage spring 610 and is inserted into the insertion groove 602, and the lower surface of the T-shaped push block 606 is arranged to be an inclined surface, so that after the inclined surface of the T-shaped push block 606 is contacted with the counterweight ball 505, the counterweight ball 505 can be pushed into the counterweight groove 510 formed in the outer surface of the turntable 502, the turntable 502 is balanced, and the turbine 303 is prevented from shaking when rotating; through the power accumulation effect of the power accumulation spring 610, the T-shaped push block 606 can quickly push the counterweight ball 505 into the counterweight groove 510, so that the turntable 502 can be more accurately weighted to reach a balanced state.

Referring to fig. 8, specifically, the lower surface of the machine body 1 close to the C-shaped frame 2 is provided with a supporting mechanism 7, the supporting mechanism 7 includes a moving column 701, a sleeve 702 and a compression spring 703, the lower surface of the C-shaped frame 2 is fixedly connected with a plurality of moving columns 701, the lower surface of the machine body 1 close to the plurality of moving columns 701 is fixedly connected with the sleeve 702, the moving columns 701 are inserted in the sleeve 702 and are arranged in a sliding manner, the outer surface of the sleeve 702 is sleeved with the compression spring 703, two ends of the compression spring 703 respectively abut against the inner surfaces of the lower surface of the C-shaped frame 2 and the machine body 1, and the elastic coefficient of the compression spring 703 can support the mechanism arranged on the C-shaped frame 2.

Thus, when the turbine 303 is not rotated stably, the turbine 303 drives the C-shaped frame 2 to move downward under the action of centrifugal force generated during rotation, so that the moving column 701 fixedly connected to the lower surface of the C-shaped frame 2 moves inward into the sleeve 702, and the compression spring 703 sleeved on the sleeve 702 is compressed accordingly, so that the C-shaped frame 2 can drive the L-shaped hook 601 to move downward, and the counterweight ball 505 is pushed into the counterweight groove 510, so as to keep the turntable 502 balanced.

Referring to fig. 9, specifically, a limiting assembly 8 is disposed at a position, close to the counterweight ball 505, of the fixed block 503, the limiting assembly 8 includes a rectangular opening 801, a circular rod 802, a pressure spring 803 and a retainer ring 804, the rectangular opening 801 is disposed at one end, close to the turntable 502, of the fixed block 503, the circular rod 802 is inserted into the lower surface of the fixed block 503, the retainer ring 804 is integrally formed on the outer surface of the circular rod 802, the pressure spring 803 is sleeved on the circular rod 802, two ends of the pressure spring 803 respectively abut against the lower surface of the retainer ring 804 and the inner wall of the rectangular opening 801, and the exhaust ports 308 are sequentially opened from small to large from the position of the air inlet pipe 305.

Thus, when the push plate 508 pushes the counterweight ball 505 to move closer to the turntable 502, the top end of the round rod 802 blocks the counterweight ball 505, so that the counterweight ball 505 cannot be pushed into the counterweight groove 510, and the turntable 502 is prevented from being configured with a wrong weight, which causes more imbalance of the turntable 502; when the T-shaped pushing block 606 pushes the weight ball 505 to move, the weight ball 505 will press the round bar 802 downwards, so that the weight ball 505 can be pushed into the weight slot 510 beyond the round bar 802, and the rotating disc 502 reaches a balanced state.

Referring to fig. 4 and 10, specifically, a filter screen 9 is fixedly connected to an inner wall of the air inlet pipe 305, and a plurality of exhaust ports 308 are sequentially opened from small to large from the position of the air inlet pipe 305.

Thus, the filter screen 9 is arranged at the inlet of the air inlet pipe 305, so that impurities cannot enter the annular air inlet disc 304, and the air outlet 308 is prevented from being blocked; since the opening size of the exhaust port 308 is sequentially opened from small to large from the position of the air inlet pipe 305, the phenomenon that the air pressure is caused to the transmission shaft 302 due to the fact that the air speed entering the exhaust port 308 close to the air inlet pipe 305 is too high, and the turbine 303 is unstable in rotation is avoided.
