[0027] The sh fry input component comprises ash fry injection slideway 8, inwhich sh fry slides from ash fry bearing container to ash fry lifting tank 6. One end ofthe sh fry injection slideway 8 is easily connected with an external sh fry bearing, and the other end ofthe sh fry injection slideway 8 is located above a culturing pond.

[0028] The pond entering component comprises a sh fry lifting tank 6. The sh fry lifting tank 6 is located below the sh fry injection slideway 8. The bottom of the sh fry lifting tank 6 is provided with a release valve 7. The top ofthe sh fry lifting tank 6 is provided with a rst xed pulley 4. One side of the rst xed pulley 4 is provided with a second xed pulley 3. The rst xed pulley 4 is provided with a braking device 5. The rst xed pulley 4 and the second xed pulley 3 are provided with a connecting rope 2. Both ends of the connecting rope 2 are provided with connecting hooks. The connecting hook at one end close to the rst xed pulley 4 is connected with the sh fry lifting tank 6 through a xed rope, and the connecting hook close to the second xed pulley 3 is provided with a balance weight 1. The rst xed pulley 4 and the second xed pulley 3 are used for reversing the pulling force ofthe connecting rope 2 to convert the vertical pulling force ofthe balance weight l into the horizontal pulling force.

[0029] The weight ofthe balance weight 1 is greater than the weight ofsh fry lifting tank 6 when it is emptied, and less than the weight ofsh fry lifting tank 6 when it is full. When the sh fry lifting tank is emptied, the sh fry lifting tank is pulled up to the height near the slideway by its own gravity. When the sh fry lifting tank is close to full load, the descending speed ofthe sh fry lifting tank is slowed down by gravity, so that the height of the sh fry lifting tank can be adjusted, the sh fry can nish being delivered, and the sh fry lifting tank can be reset.

[0030] The sh fry preserving device comprises: a mounting chassis; a damping component, which is provided above the mounting chassis and is congured to prevent sh fry from being injured due to violent vibration; an aeration rod, which is provided above the damping component and is congured to provide oxygen for sh fry, a protective frame, which is provided at the front side of the damping component; a top cover plate, which is provided above the damping component; an electric push rod, which is provided above the top cover plate; a top cover with a rubber ring, wherein the middle part ofthe top cover plate is stuffed with the top cover with the rubber ring; and a delivering component, which is provided above the protective frame and congured to deliver sh fry.

[0031] The balance rope 2 is provided on the rst xed pulley 4 and the second xed pulley 3, and is connected with the balance weight 1 and the sh fry lifting tank 6 through the connecting hooks provided at both ends ofthe balance rope 2, respectively, so as to convert the gravity of the balance weight 1 into a pulling force to control the lifting ofthe sh fry lifting tank 6.

[0032] The braking device 5 is a remotely controllable braking device 5 forbraking and controlling the lifting speed ofthe sh fry lifting tank 6.

[0033] Thesh fry lifting tank 6 ismade oflight materials. The top ofthesh fry lifting tank 6 is provided with an opening, and the bottom ofthe sh fry lifting tank 6 is funnel- shaped. The contracted bottom is connected with the release valve, which is used to load water containing sh fry, so that the sh fry is transferred from the terminal height of the slideway to the height ofthe water surface.

[0034] The release valve 7 is a remotely controlled valve.

[0035] The present disclosure relates to a method forwater containing sh fry entering a pond in a slowly lowering manner, comprising the following steps:

[0036] l) preparation, in which a sh fry lifting tank is emptied, the sh fry injection slideway is turned off, and the sh fry lifting tank is raised to a position slightly lower than the opening of the sh fry injection slideway by using the gravity of the balance weight through the braking device;

[0037] 2) injecting sh fry, inwhich the sh fry injection slideway is turned on, the sh fry and thewaterows into thesh fry lifting tankthrough thesh fry injection slideway, when the sh fry lifting tank is almost full, the sh fry injection stops, and at this time, the overall weight of the sh fry lifting tank and the sh fry is greater than the weight ofthe balance weight;

[0038] 3) controlling the speed, in which the descending speed is controlled by a braking device, and the sh fry lifting tank is lowered to the vicinity ofthe liquid level ofthe culturing pond or the release valve is submerged under the water surface;

[0039] 4) releasing sh fry, in which a release valve at the bottom ofthe sh fry lifting tank is turned on, and the sh fry is released into a culturing pond;

[0040] 5) lifting the tank, inwhich the sh fry lifting tank is raised to a position slightly lower than the opening of the sh fry injection slideway by using the gravity of the balance weight through the braking device, and the release valve is turned off;

[0041] 6) repeating step 2 to step 5 to nish delivering sh fry.

[0042] The device makes sh fry enter a pond in a slowly lowering manner. Fish fry enters a pond in a slowly lowering manner by the balance weight, the connecting rope, the xed pulley, the braking device, the sh fry lifting tank and the like. After the sh fry and water in the sh fry lifting tank are discharged into the pond, the lifting tank for transferring sh fry is restored to its original heightby the balance weight, so as to start the next workow. The device can be used for the sh fry entering the pond in the traditional culturing eld and large-scale mariculture. Compared with the scheme that the traditional crane tuck net is used to hoist the sh fry into the pond, the method of delivering the sh fry according to the present disclosure is higher in efciency, higher in stock rate ofthe sh fry and excellent in applicability. _ 7 _
