[0014] The specific implementation manner of the utility model will be described below with reference to the drawings. Figure 1 As shown in the figure: an oscillating float hydraulic wave energy power generation device, it includes sink 1, the top end surface of the sink 1 is fixedly connected with hydraulic cylinder body 3 through multiple first connecting rods 2 which are uniformly distributed in the circumferential direction, the hydraulic cylinder body 3 movably connects with piston 4, the bottom of the piston 4 is connected with the sink 1 through spring 5, the top end surface of the piston 4 is provided with second connecting rod 6, the second connecting rod 6 is movably connected on the upper plate 7 of the hydraulic cylinder body 3, and the top end of the second connecting rod 6 is connected with the bottom end surface of float 8, the upper plate 7 and the piston 4 are working cavities 9, and a water inlet is also arranged on the upper plate 7, a first one-way valve 10 is arranged at the water inlet,

[0015] A water turbine generator 11 is arranged in the inner cavity of the float 8, an inlet end of the water turbine generator 11 is connected with the operation cavity 9 through a hose 12, and an outlet end of the water turbine generator 11 is connected with a water outlet pipeline 13, a top end of the water outlet pipeline 13 is located on a top end surface of the float 8, and a second one-way valve 14 is arranged at an opening of the top end of the water outlet pipeline 13, the second one-way valve 14 allows seawater to flow out of the water outlet pipeline 13,

[0016] A guide cage 15 is arranged at a top of the hydraulic cylinder body 3, and the float 8 is movably connected in the guide cage 15,

[0017] The water turbine generator 11 is connected with a storage battery on the ship or on the bank through a current regulating circuit.

[0018] The working process of the oscillating float hydraulic wave energy power generation device is as follows: a plurality of the power generation devices are arranged in a designated sea area, the water turbine generator 11 in each power generation device is connected with the storage battery through a line, and the storage battery can be arranged on the bank or on the ship.

[0019] Under the action of the sea waves, the float 8 reciprocally moves up and down relative to the sinker 1 and the hydraulic cylinder body 3 below, when the float 8 moves downward relative to the hydraulic cylinder body 3, under the joint action of the gravity of the float 8 and the pulling force of the spring 5, the second connecting rod 6 pushes the piston 4 downward to drive the piston 4 to move downward, the volume of the operation cavity 9 becomes larger and the pressure becomes smaller, under the action of the pressure difference, the seawater outside enters the operation cavity 9 through the first one-way valve 10, and the process is a water absorption process; in the above process, the second one-way valve 10 is closed, and the operation cavity 9 is isolated from the outside atmosphere, so that the water absorption action can be realized.

[0020] When the float 8 moves upward relative to the hydraulic cylinder body 3, the piston 4 is pulled upward through the second connecting rod 6, the volume of the operation cavity 9 becomes smaller and the pressure becomes larger, and since the first one-way valve 10 does not allow seawater to flow out of the operation cavity 9, the seawater can only enter the water turbine generator 11 through the hose 12 to drive the impeller therein to rotate, the water turbine generator 11 converts the mechanical energy of the impeller rotation into electrical energy, the electrical energy is regulated into stable direct current through the current regulating circuit and then input into the storage battery for storage, and finally the seawater is discharged through the second one-way valve 14 at the tail end of the water outlet pipeline 13.

[0021] In the above process, the float 8 always moves in the range of the guide cage 15, the guide cage 15 can ensure that the movement direction of the float 8 is basically consistent with the axial direction of the hydraulic cylinder body 3, on the one hand, the first connecting rod 2 can be prevented from being deformed or damaged due to stress deflection, and on the other hand, the working efficiency of power generation can be effectively ensured.
