[0028] In the embodiments, by Figs. 1-3 An automatic fish-driving device for a fish farm's sewage outlet is provided. This utility model includes a sewage discharge frame 1 and a sewage discharge pipe 2 connected thereto. The inner wall of the sewage discharge frame 1 is provided with a rotating head 2 that affects the direction of water flow. The inner wall of the sewage discharge frame 1 is provided with a movable auxiliary sewage discharge component 3 that periodically blocks the sewage discharge pipe 2. The inner wall of the sewage discharge frame 1 is fixedly provided with a driving component 4 that drives the auxiliary sewage discharge component 3 to move. The end of the auxiliary sewage discharge component 3 is connected to an oscillation generator 5 that generates oscillation through conduction.

[0029] The rotary head 3 uses a multi-layer three-way mercury slip ring, and the outer wall of the sewage rack 1 is equipped with a drive motor 31 whose output shaft extends to its inner side and is connected to the rotary head 3.

[0030] The drive motor 21 drives the rotating head 2 to rotate via a waterproof output shaft. The speed of the motor can be controlled by a controller to adapt to the water flow speed requirements under different conditions.

[0032] The auxiliary pollution discharge component 3 is arranged in parallel on both sides of the inner wall of the pollution discharge frame 1, and is in high-precision guiding cooperation with the sliding rod through a linear bearing, so that the auxiliary pollution discharge component 3 can only move along the pollution discharge frame 1.

[0033] The auxiliary pollution discharge component 3 includes a tension spring 31 connected with the pollution discharge frame 1 and a shielding plate 32 connected with the sliding rod, the end of the tension spring 31 is embedded in the end of the pollution discharge frame 1 through a T-shaped connecting piece, the width of the shielding plate 32 is matched with the width of the pollution discharge pipe 2, the shielding plate 32 abuts against the oscillation generating component 5, and the tension spring 31 is kept in a tension state.

[0034] The pre-tightening force of the tension spring 31 makes the shielding plate 32 tightly abut against the oscillation generating component 5 in a normal state, when the driving assembly 4 pulls the shielding plate 32, the spring is energized and releases the elastic force when the shielding plate is reset, so that the oscillation generating component 5 starts to generate oscillation waves.
