Returning spring adjustment device and method for wave power system

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...

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
