When the protection mechanism 9 is unfolded, the push rod motor is started to enable the lifting frame of the lifting mechanism 8 to move, the top plate 91 is pushed upwards, when the top plate 91 moves upwards, the lifting frame on the lifting mechanism 9 deflects along the axis of the rotary table 99 at the top position of the lifting frame, at the moment, the lifting frame drives the driving shaft 910 to rotate, then the rotary table 99 rotates, when the rotary table 99 rotates, the driven shaft 98 moves towards the direction of the guide groove two 913 along the first 911 and the transfer groove 912, the driven shaft 98 moves in the direction relatively far away from the axis of the rotary table 99 when the transfer groove 912 is positioned, then the driven shaft 98 drives the driving rod 97 to move, when the driving rod 97 moves, the push rod 96 slides, the racks 915 on the vertical plates 914 at the two ends of the push rod 96 move, at the moment, the racks 915 drive gears on the turnover unit 95 to rotate, so that the sleeve and the telescopic rod deflect, and then the turnover plate 93 turns over and unfolds along the axis of the hinge 94;
When oxygen supply is needed to be carried out at the bottom of the fish nest or the fish nest floats upwards from the sediment in the river, the air pump is started, external air enters the support frame 10 after entering the air supply pipe along the air inlet pipe under the action of the air pump, then the air is sprayed onto the blades 137 from the first spray holes 139 on the baffle plate 138, the extension shaft 136 rotates, then the air enters the rotating pipe 131 along the switching pipe 134, finally the air is sprayed out from the second spray holes 133 on the rotating groove 132, the rotating pipe 131 rotates under the combined action of the spraying air flow and the blades 137 when oxygen supply is carried out, the spraying air flow rotates and is uniformly distributed at the bottom of the fish nest, the oxygen supply is uniform and full, when the rotating pipe 131 is buried by the sediment, the spraying air flow flows along the rotating groove 132, the rotating pipe 131 is separated from the sediment, and the sediment on the rotating pipe 131 is cleaned by utilizing the rotating mode, so that the fish nest is convenient to rise;
When in assembly connection, adjacent fish nest components are fixedly connected through connecting pipes on the butt joint rods 6 on the adjacent fish nest components, and traction limitation is carried out by utilizing the traction mechanism 5;
The fish nest is installed in a combined mode, is firm in structure and strong in wave resistance, can be stored and protected, is stored and sunk into the water surface in the wind wave coming or sinking process, and improves the structural safety of the fish nest; when a storm or drought comes, the position of the fish nest is adjusted to keep the fish nest at a proper depth fixed under the water surface; when the sun is exposed for a long time, when the water temperature of the water level where the fish nest is positioned is too high, the fish nest moves down to a proper water level, so that the damage of the excessive water temperature to the fish eggs is avoided; oxygen supply operation is carried out on the fish nest, dissolved oxygen in a local water area is improved, the survival rate of fish eggs is improved, the fish eggs are conveniently hatched, when the fish nest is sunk at the bottom of a river, the bottom of the fish nest is covered by sediment in the river, the fish nest is separated from the sediment at the bottom of the river by utilizing the rotating action of the rotating air supply mechanism in the air injection process, and the fish nest floats upwards conveniently.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
