The pull ring can facilitate the staff to move the connecting plate 20.

[0025] The utility model is divided into the following steps when in use:

[0026] S1: When the liquid level of the breeding box 1 needs to be controlled, the U-shaped slider 12 with the first liquid level sensor 14 is first moved, and the connecting plate 20 is pulled to drive the slide plate 17 to slide along the sliding mouth 16. At this time, the spring 19 is compressed, and the connecting plate 20 moves and drives the insertion rod 21 to move. When the insertion rod 21 is out of contact with the slot 13, the U-shaped slider 12 can be moved up and down along the square rod 10. When it moves to the required position, the connecting plate 20 is released, and the spring 19 releases the elastic force to push the slide plate 17 to move along the sliding mouth 16, and at the same time drives the connecting plate 20 to move so that the insertion rod 21 is inserted into the slot 13. Similarly, another U-shaped slider 12 with the second liquid level sensor 15 is operated, and the height of this U-shaped slider 12 is slightly lower than the previous U-shaped slider 12, so that there is a height difference;

[0027] S2: If the liquid level in the breeding tank 1 is higher than the first liquid level sensor 14, the first liquid level sensor 14 sends a signal to the controller 8, and the controller 8 opens the second solenoid valve 7 to drain water. If the water level is lower than the first liquid level sensor 14, the second solenoid valve 7 stops running. Similarly, when the liquid level in the breeding tank 1 is lower than the second liquid level sensor 15, the second liquid level sensor 15 sends a signal to the controller 8, and the controller 8 opens the first solenoid valve 6 to supply water. If the water level is higher than the second liquid level sensor 15, the first solenoid valve 6 stops running.
