[0031] The structural parameter design of the optoelectronic hydraulic mechanical potential energy gain power generation (dynamic) unit is as described below:

[0032] The initial power source is the original power of the unit. We first set the initial power source from solar energy or mains electricity to 30 KW, and then connect a Y200L-4, P_e = 30 KW motor. After power-on, a rotational speed of n_e = 1450 (rpm) is obtained.

[0063] When the set driving power is: P_drive = 25 KW:

[0064] Since Therefore, the output torque

[0065] If the set driving power is: P_drive = 30 KW:

[0066] Since Therefore, the output torque

[0067] In order to obtain the corresponding kinetic energy and increase the input torque of the generator body 200, a hydraulic fixed-displacement motor 130 of model A2F200 is connected to the output end of a hydraulic hand-operated variable pump 120 with a maximum displacement of 250 ml / r (A7V-250) to output torque and speed for the generator body 200.

[0177] This application provides a photoelectric - hydraulic - mechanical potential energy gain generator. The photoelectric system is the initial power source of the unit, and the power source can come from solar power generation or mains electricity; the hydraulic potential energy conversion device consists of motor 110, hydraulic manual variable pump 120 and hydraulic fixed - displacement motor 130. According to the third element of the three elements of force, the effect of the same force is also related to the acting position of the force. In addition, according to the research conclusion of the force ratio relationship in hydraulic and pneumatic transmissions, that is, in hydraulic and pneumatic transmissions, the working pressure depends on the load and has nothing to do with the amount of fluid flowing in. And, the thrust during operation is amplified. The rotational thrust of the plunger of the hydraulic fixed - displacement motor 130 is amplified through the main shaft disc 134 at the input end of the hydraulic fixed - displacement motor 130. Without changing the displacement and rotational speed, by using the large - diameter main shaft disc 130 in this application, as well as the setting where the extended central plunger rod 136 and the plunger rod body 137 have an inclination angle of 21°, changing the geometric dimensions of the heads of the central plunger rod 136 and the plunger rod body 137 and the output point of the slipper, increasing the lever arm of the piston on the main shaft disc 134 at the input shaft end to increase the torque, realizing the potential energy transformation and kinetic energy adjustment of the system, achieving power saving, and supplementing the shortage of power or energy for the working equipment. Under the premise of satisfying the law of conservation of energy, the problem of potential energy conversion gain of hydraulic machinery is solved.
