Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power generating apparatus using wave and wind,

More particularly, the present invention relates to a power generating apparatus using a wave and a wind force capable of generating electricity by operating a generator using wave energy periodically generated in the coast, .

Generally wind power generators are devices that convert the wind energy into electrical energy that we can use. The wind blows the wing of the wind turbine and produces electricity by the turning force of the wing. The larger the wind speed and the larger the wind turbine, the more wind energy can be produced. Therefore, the larger the wind intensity and the larger the size of the wind turbine, the more power it generates.

Currently, fossil fuels such as coal and petroleum are gradually becoming depleted as non-renewable energy sources, and environmental pollution caused by the use of fossil fuels is being questioned. Recently, pollution-free wind power generation is becoming more popular as an alternative energy source for these problems.

Due to the development of onshore wind power generation, the size of the wind turbine has been enlarged. Since wind turbine generators on land are expensive to install, a wide separation distance between the equipments is necessary for effective use of wind power. In Korea, where land purchasing and leasing costs are high, there are many difficulties in securing the required separation distance for land-based wind turbine generators. Also, windy areas are limited and limited. Moreover, because the windy areas in Korea are mainly located at mountainous areas in mountainous regions, it is difficult to carry out foundation work, and it is difficult to transport the necessary tools for installation from the flatlands to the mountainside. The mountainous area is high and the slope is steep, so the installation process is complicated and difficult.

On the other hand, in case of offshore wind turbine, it is possible to construct a large scale wind farm on the sea because there is no limit to securing the site. In addition, there are few changes in wind speed due to wind turbulence, elevation, and direction because there are no obstacles such as high buildings and mountains in the sea. For this reason, it is possible to maintain 1.5 to 2 times higher power generation with relatively low fatigue load compared with similar conditions of onshore wind power generation.

However, many problems arise in constructing wind power generation in a remote sea. In case of strong wind and rough waves due to the weather change, the columnar floating structure with a small buoyancy is seriously shaken and the materials of the wind power generator are damaged. The frame members radially connected to the column of the wind power generator and the floating structure combining the buoyancy member with the frame were installed at the sea to operate the generator. However, the buoyancy part was separated and destroyed by the rough waves and the wind power generator was maintained in the sea There are many problems. The floating structure can not be centered due to the partial deviation of the buoyancy part, or the space in which the manager moves and works is narrow and an accident occurs in the sea.
Thus, the power generation device using the power of the wave of the patent registration No. 10-1416962 (2014.7.2) proposed by the applicant of the present invention advances the ratchet rack through the wire while the buoyant body is pushed to the shore by the wave force The generator is operated by rotating the ratchet wheel so that the ratchet rack is retracted to the original position by the pulling force of the elastic member when the wave power is canceled and the generator is operated by rotating the ratchet wheel by repeating periodic forward and backward operations so that the buoyant body is returned However, such a structure has a problem that the generator is not stably and continuously operated because the rotor inside the generator is rotated only when the ratchet wheel is rotated to produce electric energy.

It is an object of the present invention to solve the problems of the prior art, and it is an object of the present invention to provide a stator and a stator which can rotate stably and continuously, The present invention also provides a power generating device using wave and wind power that can minimize the maintenance and management cost because it is a small scale that can be easily transported and installed to the seabed.

The height of the support plate 20 is automatically adjusted between the lower corner portion and the upper end of the plurality of anchors 10, And a guide pipe 22 for guiding the upper end of the buoyant body 80 to vertically move upward and downward is coupled to a lower side of the plane.

The lower side of the bracket 34 is coupled to the front end of the pedestal 32 by a fastening member 36 composed of a plurality of bolts and nuts and a pair of right and left ratchet racks 60 A pair of left and right guide rollers 38 are rotatably installed to guide the wire 82 connected to the upper surface of the buoyant body 80 by a vertical line .

The first rotary shaft 42 is coupled with a rotor 42a rotatably disposed at the center of the casing 46 of the generator 40 via a bearing 48 and is rotated simultaneously.

3, the buoyancy member 80 is raised by the buoyancy action and the upper side guide bar 80a is guided to the lower guide pipe (not shown) of the support plate 20 22 and at the same time loosens the wire 82 fixed to the upper end of the guide rod 80a.
