In addition, the scope of the present invention may be further limited by the following specific embodiments, but is not intended to limit the scope of the present invention in any way.

Please continue to refer to the first figure and the second figure. When the hydraulic power generation system of this creation is actually actuated, the power is first supplied to the variable speed motor (11) of the drive assembly (1) to start the shifting motor (11). The motor (11) drives the driving mechanism (12). In this embodiment, the driving mechanism (12) uses a crankshaft. When the shifting motor (11) rotates, the crankshaft used by the driving mechanism (12) also starts to rotate and is driven. The mechanism (12) is further connected to the rocker arm (312) of one of the pistons (311) in the hydraulic cylinder (31) of the hydraulic circuit (3). As the drive mechanism (12) rotates, the rocker arm (312) will The two pistons (311) are driven up and down in the hydraulic cylinder (31), and hydraulic oil is respectively input or outputted on both sides of the hydraulic cylinder (31), wherein the circuit unit of the hydraulic circuit (3) (33) The first circuit (331) and the second circuit (332) are both connected to both sides of the hydraulic cylinder (31), and the first circuit (331) is responsible for inputting hydraulic oil into the hydraulic cylinder (31), and second The circuit (332) is responsible for outputting hydraulic oil to the hydraulic motor (2). Thus, the first circuit (331) is divided into two oil passages connected to the two input ends of the hydraulic cylinder (31), and the second circuit (332) Divided into two oil roads At the two output ends of the hydraulic cylinder (31), a one-way valve (34) is separately disposed in the diverted oil passage, so that the hydraulic oil in the hydraulic cylinder (31) cannot be returned to the first circuit (331). The hydraulic oil in the second circuit (332) cannot be returned to the hydraulic cylinder (31); according to the piston (311) in the hydraulic cylinder (31), the creation can be divided into two kinds of dynamic samples, first The two pistons (311) are located at the bottom point in the hydraulic cylinder (31), and the second is the two pistons (311) located at the apex of the hydraulic cylinder (31).

The first type is a dynamic sample

Referring to the first figure, when the driving mechanism (12) drives the two pistons (311) in the hydraulic cylinder (31) to move to the bottom point, the piston (311) is squeezed to be originally filled in the hydraulic cylinder (31). The hydraulic oil on the bottom side causes the hydraulic oil to be pushed to the second circuit (332) connected to the output end, because the check valve (34) of the first circuit (331) is disposed in a direction that does not allow the hydraulic oil to flow back to the first circuit ( 331), so only the check valve (34) of the second circuit (332) is opened, so that the hydraulic oil is output to the hydraulic motor (2) through the second circuit (332), at which time the hydraulic oil drives the oil pressure The motor (2) starts to operate, thereby driving the output load (4) at the rear end. In this embodiment, the output load (4) is selected as a generator, so that the generator can generate electric power; and the hydraulic cylinder (31) is located at the apex side. In the part, the suction force of the vacuum is generated due to the displacement of the piston (311) to the bottom point, and the hydraulic oil of the oil tank (32) is input to the region on the vertex side in the hydraulic cylinder (31) through the first circuit (331). To fill the space vacated by the movement of the piston (311).

Referring to the second figure, when the driving mechanism (12) drives the two pistons (311) in the hydraulic cylinder (31) to move toward the apex, the piston (311) will be squeezed at the apex that is originally filled in the hydraulic cylinder (31). The hydraulic oil on the side causes the hydraulic oil to be pushed to the second circuit (332) connected to the output end, and the check valve of the first circuit (331) is not allowed to flow back to the first circuit (331). Therefore, only the check valve (34) of the second circuit (332) is opened, so that the hydraulic oil is output to the hydraulic motor (2) through the second circuit (332), at which time the hydraulic oil drives the hydraulic motor ( 2) Start operation, and drive the output load (4) of the rear end by the power of mechanical energy. In this embodiment, the output load (4) selects the generator, so that the generator can generate electric power; and the hydraulic cylinder (31) is located at the bottom. The portion on the side of the point will generate vacuum suction due to displacement of the piston (311) toward the apex, and the hydraulic oil of the oil tank (32) will be input to the bottom side of the hydraulic cylinder (31) through the first circuit (331). The area is filled with space that is freed by the movement of the piston (311).

In the present invention, the driving mechanism (12) and the piston (311) of the hydraulic cylinder (31) continuously repeat the actions of the foregoing two embodiments, which are represented by the driving mechanism (12), by the rotation of the variable speed motor (11). During one working cycle, the hydraulic oil can be output twice to the hydraulic motor (2) by the setting of one hydraulic cylinder (31); and the hydraulic oil flowing to the hydraulic motor (2) will be operated after the operation. The third circuit (333) through the loop unit (33) is returned to the oil tank (32), and when the hydraulic motor (2) is under pressure, the hydraulic pressure can be additionally transmitted through the fourth circuit (334). The oil is drained to the fuel tank (32) to increase its pressure relief rate and avoid damage to the hydraulic motor (2).

In addition, referring to the third figure, the second circuit (332) of the hydraulic circuit (3) is adjacent to the hydraulic motor (2), and is further separated from a fifth circuit (335), in the second circuit (332) or The flow control valve (35) and the discharge valve (36) may be disposed in the fifth circuit (335), and the discharge valve (36) may be disposed in parallel with the fifth circuit (335), and the flow control valve (35) is used to monitor the current Is there too much hydraulic oil in the second circuit (332)? Since the hydraulic motor (2) should set the required speed value when the creation is in use, if the hydraulic oil is too much, the hydraulic motor (2) will be The speed value exceeds the originally set speed value, so the flow control valve (35) can monitor the amount of hydraulic oil in the second circuit (332) according to the speed value set by the hydraulic motor (2), when judging that the amount of hydraulic oil is excessive , the valve is opened, and the excess hydraulic oil is released from the fifth circuit (335) and returned to the oil tank (32) to maintain the rotation speed and voltage of the hydraulic motor (2) and the output load (4) to stabilize the oil pressure.
