Problems solved by technology

[0005] The above are just two kinds, in fact there are many similar wave power generation devices that need a return spring, and for the return spring, its work is directly affected by the ever-changing ocean, sometimes the waves are more than ten meters high, and there are also tides that cause the work of the return spring The range changes, so the return spring often works beyond its reasonable range. If the tension is too large, it will cause fatigue or direct damage. If the tension is too small, the system cannot be reset. Therefore, a method is needed to adjust the spring to make it work. within a reasonable range

Embodiment Construction

[0081] Many wave power generation devices require return springs. For example, the wave power harvesting device of the one-way work method only uses the buoyancy of the wave to do work or after the wave lifts the floating body, it only uses its own gravity to do work, while the return stroke requires other forces. To reset, some rely on counterweights, and some use springs to reset. Those that use spring reset, such as the patent application CN101963125A floating body-based rope wheel wave power generation system, and the patent application CN2099205U wave power generation prime mover, both of which use the upward buoyancy and thrust to do work during the rising process of the floating body, and this process is also tightened. In the process of falling, the elastic potential energy of the spring is released to retract the rope. In the patent application 2012103827619 oscillating piston wave power generation system, when the wave height exceeds the stroke of the hydraulic cylin...

Abstract

A return spring adjustment apparatus and method of a wave power system. The apparatus comprises return springs (5, 9), a stepper motor (6), transducers (7, 10, 27, 29), a single chip microcomputer control module (8) and a power source. The two ends of the return springs (5, 9), a chassis (12) of the stepper motor, a rotor (11), the two ends of the transducers (7, 10, 27, 29) can all be randomly arranged in series, and connected with a spindle (4) and a frame (22). When a single chip microcomputer detects that the transducers (7, 10, 27, 29) measure that the pulling force is too large or too small, it sends an instruction to the stepper motor (6) to perform adjustment. After the adjustment is completed, the stepper motor (6) stalls and brakes, so that the return springs (5, 9) can work in within a specified range.

Description

technical field [0001] The invention relates to a return spring adjusting device of a wave power system. Background technique [0002] Ocean wave energy is an endless renewable energy resource. How to use such abundant energy resources to serve human beings is an important topic that the predecessors and modern people have been studying. Using wave energy to generate electricity is one of the major topics. [0003] To utilize wave energy, there must first be a wave energy collection device. For now, the wave energy collection device mainly includes an oscillating water column, a pendulum plate, a rocker, a raft type using two floating body angles, and a vertical floating body using two floating bodies. The relative motion of the oscillating float, etc., belongs to the reciprocating energy that is absorbing and transforming. [0004] However, there is another wave power collection device, which uses a one-way work method, that is, only uses the buoyancy of the wave to do wor...
