The intermediate storage tank 4 is fixed in the outer shell 1, and the intermediate storage tank 4 is connected to the oil injection member 3. The oil regulator 5 is fixed in the outer shell 1, and the oil regulator 5 is connected to the intermediate storage tank 4. The plurality of hydraulic pistons 6 are fixed in the housing 1, and the plurality of hydraulic pistons 6 are arranged in sequence along the first direction X, and the orthographic projections of the plurality of hydraulic pistons 6 on the plane perpendicular to the first direction X are arranged in a circle, and the plurality of hydraulic pistons 6 are communicated with the oil regulator 5, and the oil regulator 5 injects hydraulic oil into the plurality of hydraulic pistons 6 in sequence. The crankshaft 7 is arranged in the housing 1 along the first direction X, and the plurality of hydraulic pistons 6 are also hinged to the crankshaft 7. The oil storage tank 8 is relatively fixed to the housing 1, and the hydraulic pistons 6 and the oil injection piece 3 are communicated with the oil storage tank 8. The power generation component 9 is fixedly connected to one end of the crankshaft 7, and the crankshaft 7 has a tendency to drive the power generation component 9 to operate and generate electricity.

[0021] The crankshaft 7 includes: a main journal 71, a connecting rod journal 72, a crank arm 73 and an end 74. The plurality of main journals 71 are arranged along the first direction X, and the center lines of the plurality of main journals 71 are collinear. The plurality of connecting rod journals 72 are arranged along the first direction X, and a connecting rod journal 72 is arranged between two adjacent main journals 71, and the orthographic projections of the plurality of connecting rod journals 72 on a plane perpendicular to the first direction X are arranged in a circumferential manner, and the angle between two adjacent orthographic projections of the plurality of connecting rod journals 72 on a plane perpendicular to the first direction X is the same as the angle between two adjacent orthographic projections of the plurality of hydraulic pistons 6 on a plane perpendicular to the first direction X. The main journal 71 is fixedly connected to the connecting journal by a crank arm 73. An end 74 is fixed on each side of the plurality of main journals 71 and the plurality of connecting rod journals 72, and the end 74 is also connected to the bearing of the housing 1.

[0022] The oil regulator 5 includes: an oil regulating pipe 51, a partition plate 52 and an oil regulating shaft 53. The oil regulating pipe 51 is fixedly connected to the housing 1, and a plurality of oil inlets are arranged on the side wall of the oil regulating pipe 51, and a plurality of oil outlets are also arranged on the side wall of the oil regulating pipe 51. A plurality of annular partition plates 52 are fixed in the oil regulating pipe 51 along the center line of the oil regulating pipe 51. The oil regulating shaft 53 is a rod, and the oil regulating shaft 53 is arranged in the oil regulating pipe 51.

[0023] Each oil outlet on the oil regulator 5 is connected to a corresponding hydraulic piston 6 , and the oil regulator 5 is configured to connect multiple hydraulic pistons 6 to the intermediate storage tank 4 in sequence under the drive of the crankshaft 7 .

[0024] In some examples, the number of oil grooves on the oil regulating shaft 53 is consistent with the number of hydraulic pistons 6, and the multiple oil grooves are arranged in sequence, and the offset angle between two adjacent oil grooves is consistent with the angle between two adjacent hydraulic oil plugs. When the oil regulating shaft 53 rotates, the oil grooves rotate accordingly, and within a certain angle range, the oil inlet of the oil regulating pipe 51 is connected to the corresponding oil groove and is connected to the corresponding oil outlet.

[0025] The rotation speed of the oil regulating shaft 53 is the same as that of the crankshaft 7, that is, each hydraulic piston 6 is connected to a specific oil tank, the oil inlet of the oil regulating pipe 51 and the oil outlet of the oil regulating pipe 51. It is only necessary to control the connection sequence between multiple oil tanks and the intermediate storage tank 4 to control the operation of multiple hydraulic pistons 6 in sequence.

[0026] It should be added that a third one-way valve is provided between the hydraulic piston 6 and the oil tank, and a fourth one-way valve is provided between the hydraulic piston 6 and the oil storage tank 8.

[0027] In addition, the arrangement of the oil inlet and the oil outlet on the oil regulating pipe 51 is adapted to the oil tank. Specifically, by notifying the positions of the oil inlet and the oil outlet as well as the lengths of the oil inlet and the oil outlet, it is ensured that two or more adjacent hydraulic pistons 6 can be connected to the intermediate storage tank 4 at the same time, so that multiple adjacent hydraulic pistons 6 can be extended outward at the same time, which is suitable for some examples with a large number of hydraulic pistons 6.

[0028] The present application also provides a misalignment angle between two adjacent connecting rod journals 72, so that when the hydraulic piston 6 extends outward, the angle between the connecting line between the connecting rod journal 72 and the main journal 71 and the center line of the hydraulic piston 6 can be maintained within a larger range, so that the effective work done by the hydraulic piston 6 on the crankshaft 7 is higher.

[0029] The buoyancy member 2 is a plate member, and one end of the buoyancy member 2 is hinged to the outer upper end of the shell 1 .

[0030] The oil injection member 3 includes an oil injection pipe 31 and an oil injection piston 32. The oil injection pipe 31 is a pipe with an opening at the upper end. The lower end of the oil injection pipe 31 is hinged to the lower end of the housing 1.

A first one-way valve is provided between the oil injection inlet and the oil storage tank 8. The oil injection outlet is connected to the intermediate storage tank 4. A second one-way valve is provided between the oil injection outlet and the intermediate storage tank 4. The oil injection piston 32 is provided in the oil injection pipe 31, and the other end of the oil injection piston 32 is hinged to the end of the buoyancy member 2 away from the housing 1.

[0031] The intermediate storage tank 4 is a pressure vessel.

[0032] The star-shaped water floating power generation device further comprises a connecting rod, and each hydraulic piston 6 is hinged to the crankshaft 7 via the connecting rod.

[0033] The power generation component 9 includes a generator, and the crankshaft 7 is also fixedly connected to the input shaft of the generator.

[0034] The specific operation process of this application is as follows: In the present application, the housing 1 is placed in a lake or river with waves, the upper part of the housing 1 is higher than the horizontal level, and the buoyancy member 2 is floated to the water surface by the buoyancy. When there are waves, the buoyancy member 2 swings up and down from the hinge. The operation of the buoyancy member 2 pushes the oil injection piston 32 of the oil injection member 3 to reciprocate, injecting the hydraulic oil into the intermediate storage tank 4, so that the hydraulic oil pressure in the intermediate storage tank 4 is relatively high.

[0035] The hydraulic oil in the intermediate storage tank 4 will enter one or more oil grooves of the oil regulator 5 and enter the corresponding hydraulic piston 6 to drive the crankshaft 7 to rotate, while controlling the operation of the oil regulator 5 to realize the sequential operation of multiple hydraulic pistons 6. The crankshaft 7 also drives the generator to generate electricity.

[0036] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
