Novel concussion float type electric generator using sea wave energy

Technical field

The utility model relates to a kind of novel concussion float type electric generator using sea wave energy, a specifically being fixed on the ocean platform, and the device that utilizes the wave energy phugoid motion to generate electricity belongs to wave energy development technique field.

Background technique

In recent years, be accompanied by the exhausted day by day of earth mineral fuel, the too high negative effect that greenhouse effect and environmental destruction produced that brings of carbon emission amount is day by day serious, and people more and more pay attention to the exploitation of new energy.Earth surface long-pending 71% is the ocean, and the ocean is the huge energy, is mainly tidal energy, wave energy, energy by ocean current, thermal gradient energy of sea water etc.Wave energy is to contain one of the abundantest energy in the marine energy, it is estimated that the theoretical value of whole world wave energy is about 10 ⁹KW is hundreds of times of present world generated energy, and wide commercial promise is arranged, and countries in the world have also dropped into great amount of manpower and financial resources are researched and developed it for many years.

At present, the wave energy principal mode of the exploitation canard of nodding, the concussion water column type, concussion float type and pendulum-type, many countries have also built up some power stations in succession, and the production that drops into generating is used.But these power station great majority all are to maximize, and industrial equipment, its expenditure of construction are quite expensive, build also very big of difficulty, and compact apparatus is then less relatively, has greatly restricted the development need of wave energy.

Therefore, the utility model has been developed a concussion float type electric generator using sea wave energy, and it utilizes heaving of the sea to be used for driving float and moves up and down; And through driving mechanism moving up and down of float is converted into the uninterrupted running of generator; Efficient is high, and it is simple in structure, manufacturing and easy to maintenance; Cost is low, has very important social benefit and economic benefit for the development and use of further promotion wave energy.

The model utility content

Problems such as the utility model provides a kind of novel concussion float type electric generator using sea wave energy, and it is expensive that its main purpose is to solve present wave energy generating set expenditure of construction, and difficulty of construction is big.

For realizing above-mentioned purpose, the technical solution of the utility model is:

The novel concussion float type electric generator using sea wave energy that the utility model provides is a kind of miniaturization, and low power wave energy generating set includes wave energy absorption plant, transmission device, output unit and base; The wave energy absorption plant is made up of float and connecting rod and is fixed on the transmission device by connecting rod, and this device is mainly used in the potential energy that absorbs the wave dipping and heaving; Transmission device comprises the double rack parts, and bidentate wheel component and output shaft are connected with output unit by coupling then, and this device is mainly used in and converts the mechanical energy that continues rotation into absorbing the wave energy that comes; Output unit is made up of generator, speed increaser and coupling, and this device is mainly used in mechanical energy is converted into electric energy; Package unit is fixed as one by base.

Described bidentate wheel component contains a wheel hub and two gear rings; This two gear ring is enclosed within on this wheel hub together; And be equipped with ratchet and pawl arrangement between each gear ring and the wheel hub, therefore, when tooth bar moves up and down; Have only a gear ring to have pair wheel hub effect and drive hub to continue rotation, realize converting wave energy into continue rotation mechanical energy along same direction.

Two tooth bar parallel misalignments on the described double rack parts, and connect as one by a fixed plate, and also be provided with chute at the back of per tooth bar.

After adopting such scheme, the utlity model has following advantage:

(1) transmission device adopts double rack and bidentate wheel mechanism, and in the bidentate wheel component, establishes ratchet and pawl arrangement, and the rippling with wave is converted into lasting rotatablely moving simply;

(2) whole device is except connecting rod and float, and other all is fixed on the base, simple structure, and reliable performance effectively reduces cost of electricity-generating.

In sum, defective such as it is loaded down with trivial details that the utility model has effectively overcome conventional installation, and using scope is little has very important social benefit and economic benefit for the development and use of further promotion wave energy.

Below in conjunction with accompanying drawing and practical implementation, this novel concussion float type electric generator using sea wave energy is further specified.
