Straight line wave power generator based on magnetic gear

Abstract

The invention relates to a straight line wave power generator based on a magnetic gear, solving the defects of large volume, complicated system and low efficiency of a motor used in the wave power generation by compounding a line power generator with the magnetic gear. The invention realizes the integration of the magnetic gear and the line power generator by removing the high-speed side of the traditional magnetic gear. The straight line wave power generator comprises a power generator primary winding and a power generator secondary winding, wherein the power generator primary winding comprises a primary iron core (1), a primary winding (2) and a magnetic adjusting ring (3); the magnetic adjusting ring (3) is distributed between the primary winding (2) and a permanent magnet (4) along the axial direction of a cylinder and fixed on the primary iron core (1), and the primary winding (2) is embedded in a wire slot of the primary iron core (1) which is fixed on the bottom of water; the power generator secondary winding comprises a permanent magnet (4) and a rotor iron core (5); and the low-speed side of the magnetic gear is the permanent magnet (4), and uniformly attached on the surface of the rotor iron core (5) along the axial direction of the cylinder, the rotor iron core (5) is fixed in a floating cylinder (6), and the rotor iron core and the floating cylinder as an integer float on a water level (7).

Description

technical field [0001] The invention relates to a novel linear wave generator based on a magnetic gear, which adopts the magnetic gear to adjust the speed, and belongs to the technical field of wave power generation. Background technique [0002] Water bodies contain huge energy. Today, when the world's energy is increasingly tense, wave power generation has become an important direction for the development of new energy. Traditional wave power generation uses rotating motors, which have low efficiency and poor durability at low speeds, which have become important factors restricting the development of wave power generation. In recent years, Chinese scholars have proposed using linear motors to directly use the up and down vertical displacement of waves as power to drive the secondary linear motion of the motor to generate electric energy, which can improve the efficiency and life of the entire system. However, due to the low speed of the wave movement, the traditional use ...

Problems solved by technology

However, due to the low speed of the wave movement, the traditional use of a gearbox as an intermediate link for speed regulation to increase the secondary speed of the motor, while the gearbox increases the volume and weight of the entire transmission system, and there are also problems such as noise, wear, and long response time.
