Abstract

The invention discloses a modularized sea wave direct drive generator, comprising a floater and a sea wave direct drive generator which are arranged on a bracket from bottom to top, wherein the input driving end of the sea wave direct drive generator is connected with the floater; and the output end of the sea wave direct drive generator is connected with a series-parallel connection module. The sea wave direct drive generator comprises a sleeve, a stator coil, a rotor magnet and a driving rod, wherein the stator coil is arranged in the sleeve; the rotor magnet is arranged at the inner side of the stator coil; one end of the driving rod is inserted in the inner side of the stator coil and is connected with the rotor magnet through a flexible connecting structure, and the other end of the driving rod is arranged at the outer side below the sleeve and is connected with the floater; a sealing cover is arranged at the top end of the sleeve; and a wire outlet is arranged on the sealing cover. The main parts of the modularized sea wave direct drive generator are located above the sea surface and are packaged in the sleeve, and therefore, the damage probability of the main parts is reduced. The modularized sea wave direct drive generator is low in use cost in the life cycle and is suitable for large-scale production and use, and the development and utilization of the sea wave energy are strengthened.

Description

Technical field [0001] The invention relates to a generator. In particular, it relates to a modular ocean wave direct-drive generator that uses ocean wave energy to generate electricity. Background technique [0002] Wave energy has the advantages of being widely distributed, large in total, clean and pollution-free. Wave power is the main way to use wave energy, but there are also three problems that hinder the development and utilization of wave energy: [0003] 1. Wave energy is dominated by wave energy of vertical motion; 2. Wave energy is distributed in a scattered plane; 3. Energy density is very low. [0004] The existence of these three problems makes the development and utilization of wave energy different from general hydropower development. The generators that are now widely used are generally rotating electric machines, which cannot be directly used for wave power generation. The planar distribution of wave energy requires the power generation device to include the fun...
