[0041] Specifically, the output end of oxygenation pump 301 is connected with shunt pipe 302 by connecting pipe, and shunt pipe 302 uniformly distributes oxygen into multiple elastic connecting pipes 303, which are annularly distributed on shunt pipe 302, increasing the flexibility and coverage of oxygen delivery, the other end of elastic connecting pipe 303 is connected with air guide pipe 304, and multiple equidistant distribution, radial arrangement of branch aeration pipe 305 are installed on both sides of each air guide pipe 304, so that oxygen can be uniformly and widely released into water area through branch aeration pipe 305, realizing effective oxygenation.

[0042] Wherein, expansion assembly 4 includes: drive motor 401, drive motor 401 is fixedly installed in the cavity of connecting column 1;Driving screw rod 402, driving screw rod 402 rotates in the cavity of connecting column 1, and one end is fixed with the output end of drive motor 401;Driven threaded block 403, driven threaded block 403 is threadedly connected on driving screw rod 402;Connection strip one 404, one end of connection strip one 404 is hinged with driven threaded block 403, connection strip one 404 is equipped with the same number of air guide pipes 304, and is annularly and uniformly distributed on driven threaded block 403;Connection plate 405, one end of connection plate 405 is hinged with the other end of connection strip one 404;Connection strip two 406, one end of connection strip two 406 is hinged with connecting column 1, and the other end of connection strip two 406 is hinged with the end of connection plate 405 away from connection strip one 404.

[0043] Specifically, when the driving motor 401 starts, the driving threaded rod 402 rotates, and the driven threaded block 403 moves up and down linearly in the cavity of the connecting column 1.
