[0021] See Figures 1 to 3 , in a further embodiment, a driving member 71 is provided at the top of the rotating shaft 4. The rotating shaft 4 is connected to the output shaft of the driving member 71. At the same time, the driving member 71 is connected to the floating platform 7. The floating platform 7 can ensure that the driving member 71 does not sink to the bottom of the water, and it is also convenient for the staff to control the rotation of the output shaft of the driving member 71.

[0022] See Figures 1 to 3, in a further embodiment, a first ratchet wheel 81 is provided at one end of the reciprocating rod 8, a first one-way pawl (not shown in the figure) cooperating with the first ratchet wheel 81 is provided on the rotating shaft 4, a second ratchet wheel 51 is provided at one end of the reciprocating lead screw 5, and a second one-way pawl (not shown in the figure) cooperating with the second ratchet wheel 51 is provided on the rotating shaft 4. When the output shaft of the driving member 71 rotates forward, the first ratchet wheel 81 and the first one-way pawl cooperate, that is, the rotating shaft 4 drives the reciprocating rod 8 to rotate, and the second ratchet wheel 51 and the second one-way pawl do not cooperate, that is, the rotating shaft 4 does not drive the reciprocating lead screw 5 to rotate. When the output shaft of the driving member 71 rotates reversely, the second ratchet wheel 51 and the second one-way pawl cooperate, that is, the rotating shaft 4 drives the reciprocating lead screw 5 to rotate, and the first ratchet wheel 81 and the first one-way pawl do not cooperate, that is, the rotation does not drive the reciprocating rod 8 to rotate. The first ratchet wheel 81 and the second ratchet wheel 51 are reverse and both are internal ratchet wheels. The cooperation modes of the first ratchet wheel 81 and the first one-way pawl, and the second ratchet wheel 51 and the second one-way pawl are all prior arts and will not be elaborated in this specification.

The telescopic sleeve 9 can block the air duct 2. That is, when the amount of aeration needs to be reduced, the output shaft of the driving member 71 rotates forward, the rotation drives the reciprocating rod 8 to rotate, the reciprocating rod 8 cooperates with the top of the telescopic sleeve 9 to drive the telescopic sleeve 9 to extend, thereby blocking part of the air duct 2. On the contrary, when the amount of aeration needs to be increased, the reciprocating rod 8 drives the telescopic sleeve 9 to descend, reducing the blockage of the air duct 2. The top of the reciprocating rod 8 is flush with the top of the aeration cylinder 1, that is, the telescopic sleeve 9 can block all the air ducts 2, and at the same time, the bottom of the reciprocating rod 8 is lower than the bottommost air duct 2, that is, the telescopic sleeve 9 can also completely not block the air duct 2.

[0025] See Figures 1 to 3, in a further embodiment, a plurality of connecting rods 61 are provided at the bottom of the reciprocating block 6. One end of the connecting rod 61 is connected to the top of the aeration cylinder 1. When aeration at different depths is required, the output shaft of the driving member 71 rotates in reverse, the rotating shaft 4 drives the reciprocating lead screw 5 to rotate, the reciprocating lead screw 5 drives the reciprocating block 6 to cycle up and down. Further, the reciprocating block 6 drives the aeration cylinder 1 to reciprocate up and down through the connecting rod 61, thereby adjusting the depth of the aeration cylinder 1 in the water at any time, improving the aeration efficiency, and at the same time facilitating the retraction of the aeration cylinder 1 for easy maintenance.

[0026] See Figures 1 to 3 , in a further embodiment, the driving member 71 is a rotary motor.

[0027] During the implementation of the present utility model: when the amount of aeration needs to be adjusted, the output shaft of the driving member 71 rotates forward, the first ratchet 81 and the first one-way ratchet pawl cooperate, that is, the rotating shaft 4 drives the reciprocating rod 8 to rotate, the second ratchet 51 and the second one-way ratchet pawl do not cooperate, that is, the rotating shaft 4 does not drive the reciprocating lead screw 5 to rotate, the reciprocating rod 8 cooperates with the top of the telescopic sleeve 9 to drive the telescopic sleeve 9 to extend, thereby blocking part of the air duct 2. Conversely, when the amount of aeration needs to be increased, the reciprocating rod 8 drives the telescopic sleeve 9 to descend, reducing the blockage of the air duct 2. The top of the reciprocating rod 8 is flush with the top of the aeration cylinder 1, that is, the telescopic sleeve 9 can block all the air ducts 2. At the same time, the bottom of the reciprocating rod 8 is lower than the bottommost air duct 2, that is, the telescopic sleeve 9 can also completely not block the air duct 2. When the aeration height needs to be adjusted, when the output shaft of the driving member 71 rotates in reverse, the second ratchet 51 and the second one-way ratchet pawl cooperate, that is, the rotating shaft 4 drives the reciprocating lead screw 5 to rotate, the first ratchet 81 and the first one-way ratchet pawl do not cooperate, that is, the rotation does not drive the reciprocating rod 8 to rotate. The rotating shaft 4 drives the reciprocating lead screw 5 to rotate, the reciprocating lead screw 5 drives the reciprocating block 6 to cycle up and down. Further, the reciprocating block 6 drives the aeration cylinder 1 to reciprocate up and down through the connecting rod 61, thereby adjusting the depth of the aeration cylinder 1 in the water at any time.
