A right side cover 39 is fixedly arranged at one end of the machine body 34 close to the wind turbine, and a left side cover 40 is fixedly arranged at the other end of the machine body 34.

The right side cover 39 and the left side cover 40 cooperate to seal a cavity 74 provided in the interior of the body 34 for mounting a power transmission assembly.

An eccentric shaft 45 for transmitting power to the power transmission assembly is arranged in the middle of the right side cover 39, one end of the eccentric shaft 45 penetrates through the right side cover 39 and extends for a certain distance into the cavity 74, and the other end of the eccentric shaft 45 is coaxially and fixedly connected with the wind turbine shaft 12.

And a high-pressure sealing ring 46 for sealing the cavity 74 is arranged at the position of the right side cover 39 corresponding to the eccentric shaft 45, and the high-pressure sealing ring 46 is in rotary connection with the eccentric shaft 45.

The power transmission assembly includes an eccentric shaft bearing 44 fixedly mounted on the eccentric shaft 45 at the location of the cavity 74, the eccentric shaft bearing 44 being eccentrically mounted on the eccentric shaft 45.

A plurality of side bearings 33 for supporting the eccentric shaft bearing 44 to rotate in the cavity 74 are respectively provided between the eccentric shaft bearing 44 and the right and left side covers 39 and 40.

The inner wall of the cavity 74 is annularly provided with a plurality of second cylinder sleeves 42.

The second pistons 35 are respectively installed inside the second cylinder sleeves 42 in a sliding mode, and the shapes of the second pistons 35 are matched with the shapes of the second cylinder sleeves 42.

One end of the second piston 35 is connected to a second connecting rod 38.

The second cylinder cover 36 is detachably mounted at a position of the second cylinder sleeve 42 corresponding to the engine body 34, and the second cylinder cover 36 is used for sealing the second cylinder sleeve 42.

The second cylinder head 36 is opened with a second fluid inlet/outlet 37 for the supercritical fluid 10 to pass through, and the second fluid inlet/outlet 37 is used for controlling the inlet and outlet of the supercritical fluid 10.

A sealing ring 75 for sealing the second cylinder sleeve 42 is fixedly mounted at the joint of the second cylinder cover 36 and the machine body 34.

An oil scraper ring 76 for preventing the supercritical fluid 10 in the second cylinder sleeve 42 from flowing out is annularly sleeved on the second piston 35.

The outer part of the tile end of the second connecting rod 38 is movably sleeved with a snap ring 43, and the snap ring 43 can enable the connecting rod to lean against the outer circle of the eccentric shaft bearing more firmly.

In operation, the wind motor shaft 12 drives the eccentric shaft 45 to rotate, and transmits power to the eccentric shaft bearing 44, the eccentric shaft bearing 44 in turn drives the second connecting rod 38 to operate, and the second connecting rod 38 drives the second piston 35 to reciprocate in the second cylinder sleeve 42 to extrude the supercritical fluid 10, so as to meet the operating requirement.

Example 3: as shown in fig. 7 to 8, this embodiment is an improvement of the supercritical fluid high power wind power generator of embodiment 1, which includes all the technical features of the supercritical fluid high power wind power generator of embodiment 1, and the improvement is in the whole structure of the supercritical fluid motor 6.

The supercritical fluid motor 6 comprises a gear motor shell 65 fixedly installed inside the shell 2, and the gear motor shell 65 is communicated with the fluid tank 8 through the fluid pipeline 3.

The gear motor housing 65 is rotatably provided with a rotating component for driving the supercritical fluid 10 to flow.

A gear motor fluid inlet and outlet 68 for the supercritical fluid 10 to enter and exit is formed in the side wall of the gear motor housing 65, and the gear motor fluid inlet and outlet 68 is communicated with the inner cavity of the gear motor housing 65.

The rotating assembly includes a gear motor power shaft 69 rotatably mounted within the interior cavity of the gear motor housing 65.

A key body 70 is fixedly mounted on the gear motor power shaft 69.

The gear motor power shaft 69 is fixedly sleeved with a helical gear 67.

By adopting the design, the key body 70 is arranged between the bevel gear 67 and the power shaft 69 of the gear motor, so that the bevel gear 67 can be more stable in rotation, and reliable power can be provided for work.

A gear motor driven shaft 66 parallel to the gear motor power shaft 69 is rotatably mounted in the interior cavity of the gear motor housing 65.

The same bevel gear 67 is fixedly sleeved on the gear motor driven shaft 66, and the bevel gear 67 on the gear motor driven shaft 66 is meshed with the bevel gear 67 on the gear motor power shaft 69.

The middle part of the two meshed helical gears 67 is provided with a fluid inlet 71 for the supercritical fluid 10 to pass through.

The teeth grooves 72 are formed between the two mutually engaging helical gears 67.

So designed, the gullets 72 facilitate expansion of the supercritical fluid 10 to improve efficiency.

The gear motor driven shaft 66 is coaxially detachably connected with the power input end of the generator 7.

In operation, the flow of supercritical fluid 10 through tooth spaces 72 drives the rotation of helical gear 67, which in turn drives the rotation of gear motor driven shaft 66, and gear motor driven shaft 66 transmits power to generator 7, and generator 7 performs power generation operation.

In the present invention, the first fluid inlet/outlet 28, the second fluid inlet/outlet 37, the motor fluid inlet/outlet 61, and the gear motor fluid inlet/outlet 68 are all described as one-way channels, and in actual operation, one is necessarily an inlet, and the other is an outlet.

In the invention, the supercritical fluid motor 6 and the generator 7 are both arranged inside the shell 2, and in actual operation, because the supercritical fluid motor 6 is communicated with the fluid tank 8 and the fluid pump 4 through the fluid pipeline 3, the supercritical fluid motor 6 and the generator 7 can also be arranged on the ground or at other positions, and because the properties of the supercritical fluid 10 and the gas are very similar, the situation of insufficient pressure caused by the overlong fluid pipeline 3 does not need to be considered.

It will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in the embodiments described above without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims.
