The working principle of the invention is as follows: initially, the channel on the regulator valve 305 is disposed perpendicular to the first and second chambers, and the first and second chambers are separated by the regulator valve 305; when the regulating valve 305 rotates 90 degrees, the channel groove on the regulating valve 305 is completely communicated with the first chamber and the second chamber; when the regulating valve 305 rotates from 135 degrees to 90 degrees, the angle between the channel groove on the regulating valve 305 and the communication position of the first chamber and the second chamber is gradually increased; as the regulator valve 305 rotates from 135 degrees to 180 degrees, the angle at which the channel slot on the regulator valve 305 communicates with the first and second chambers becomes progressively smaller.
When the power device (including but not limited to wind power, hydraulic power and internal combustion engine) drives the driving shaft 201 to rotate, the driving shaft 201 has a certain rotation speed (for convenience of explanation, the rotation speed of the driving shaft 201 is assumed to be 1500 r/min), the driving shaft 201 drives the turbine blade II 208 to rotate, meanwhile, the driving shaft 201 drives the sun gear 205 to rotate, the sun gear 205 drives the planet carrier 202 and the gear ring 203 to rotate through the planet gear 204, and the planet carrier 202 drives the turbine blade I207 to rotate through the connecting shaft I206; the driving shaft 201 drives the impeller in the centrifugal pump 602 to rotate, under the action of centrifugal force, hydraulic oil in the hydraulic cylinder 601 is extruded to a piston rod on the hydraulic cylinder 302 through the hydraulic pipe 603, the piston rod of the hydraulic cylinder 302 drives the rack 303 to slide on the supporting rod 306, the spring 307 is compressed, the rack 303 drives the regulating valve 305 to rotate 135 degrees through the gear 304, the cavity I is communicated with the cavity II through a channel groove on the regulating valve 305, the turbine blade 208 drives liquid to flow into the cavity I along the cavity II through a channel groove on the regulating valve 305, when the liquid flows into the turbine blade 207 through the cavity I, rotation of the turbine blade 207 is limited, the turbine blade 207 drives the planet carrier 202 through the connecting shaft I206 to reduce speed, the driving shaft 201 drives the sun wheel 205 to rotate, and the speed of the planet carrier 202 is smaller, therefore, the speed of the sun wheel 205 is larger than the speed of the planet carrier 202, the sun wheel 205 drives the gear 203 to rotate through the planet wheel 204, and the input end of the generator 501 is driven by the gearbox 401 to rotate when the gear 203 rotates, so that the generator 501 generates electricity.
When the rotation speed of the power device on the driving shaft 201 becomes high (for convenience of explanation, the rotation speed is assumed to be more than 1500 r/min), the driving shaft 201 drives the rotation speed of the sun gear 205 to become high, the driving shaft 201 drives the rotation speed of the impeller in the centrifugal pump 602 to become high, the centrifugal force becomes high, hydraulic oil in the hydraulic cylinder 601 presses the piston rod on the hydraulic cylinder 302 through the hydraulic pipe 603, the extending length of the piston rod of the hydraulic cylinder 302 becomes long, the moving distance of the rack 303 becomes long, the rack 303 drives the regulating valve 305 to rotate from 135 degrees to 180 degrees through the gear 304, the angle of the communicating part between the channel groove on the regulating valve 305 and the first chamber and the second chamber becomes small, the liquid flowing from the first chamber to the first chamber becomes small, and the retarding force received by the first turbine blade 207 becomes small, so that the rotation speed of the planet carrier 202 becomes large; at this time, the rotational speed of the carrier 202 increases, and the rotational speed of the sun gear 205 also increases, so that the rotational speed of the ring gear 203 is kept constant, and further, the problem of increasing the rotational speed of the input end of the generator 501 due to the increase in the rotational speed of the power plant can be prevented, and the problem of ultimately increasing the output frequency of the generator 501 due to the increase in the rotational speed of the power plant can be prevented.
When the rotation speed of the power device on the driving shaft 201 is reduced (for convenience of explanation, the rotation speed is assumed to be less than 1500 r/min), the rotation speed of the driving shaft 201 driving the sun gear 205 is reduced, the rotation speed of the driving shaft 201 driving the impeller in the centrifugal pump 602 is reduced, the centrifugal force is reduced, hydraulic oil in the hydraulic cylinder 601 presses the piston rod on the hydraulic cylinder 302 through the hydraulic pipe 603, the extending length of the piston rod of the hydraulic cylinder 302 is shortened under the elasticity of the spring 307 and the torsion force of the torsion spring 308, the moving distance of the rack 303 is shortened, the rack 303 drives the regulating valve 305 to rotate from 135 degrees to 90 degrees through the gear 304, the angle between the channel groove on the regulating valve 305 and the communication position between the first chamber and the second chamber is increased, so that liquid flowing from the second chamber to the first chamber is increased, the retarding force applied to the first turbine blade 207 is increased, and the rotation speed of the planet carrier 202 is reduced; at this time, the rotation speed of the sun gear 205 is reduced, the rotation speed of the carrier 202 is also reduced, and the rotation speed of the ring gear 203 is kept unchanged, so that it is possible to prevent the problem that the rotation speed of the input end of the generator 501 is reduced due to the reduction of the rotation speed of the power unit, and it is possible to prevent the problem that the output frequency of the generator 501 is reduced due to the reduction of the rotation speed of the power unit.
