Abstract

The utility model relates to a sea wave turbine, comprising two ratchet wheels connected with each other through a chain belt; bearings are mounted inside of the two ratchet wheel; several baffles are fixed on the chain belt; the free rotation directions of the two ratchet wheels are reversed, wherein if the clockwise rotated ratchet wheel rotates anticlockwise, the inside bearing will rotate together, while if the anticlockwise rotated ratchet wheel rotates clockwise, the inside bearing will rotate together; and two bearings mounted inside of the two ratchet wheels separately are connected with the generator through two couplings. For the sea wave turbine of the utility model, because the sea wave can always supply power to the generator whether moving forwards or backwards, the generator can generating electricity continuously with advantages of low cost, high efficiency, broad application and clean energy resources.

Description

A kind of wave water turbine

Technical field

The utility model relates to a kind of wave water turbine.

Background technique

The huge energy is being contained in the sea, many tidal power generating devices are arranged at present, exactly in the bay or there is one of the river mouth building of morning and evening tides to block the water dykes and dams, form reservoir, and placement hydraulic generator unit in the dam or by the dam, the lifting of sea level fluctuations when utilizing tiding promotes the generating of hydraulic generator unit when making seawater pass through water turbine.From the angle of energy, utilize the potential energy and the kinetic energy of seawater exactly, be converted into electric energy by hydraulic turbine generator.

Tidal power generation is a kind of renewable energy sources of cleaning, but exist the dynamo-electric investment of civil engineering big, the cost height, it is difficult to safeguard, tidal range and head often changed in one day, intermittence is arranged, and cooperate relatively poor by the figure of electric load day by day that provides solar day, but can not be used shortcoming such as energy utilization rate is low for wave.

The model utility content

The purpose of this utility model is to provide a kind of wave water turbine, and it is arranged on the longshore water surface, utilizes wave, and promptly the back and forth movement of seawater is a power, continues generating.

For achieving the above object, the utility model provides a kind of wave water turbine, and it comprises two ratchets that connect by chain belt, and described two ratchet inside stud with bearing respectively, are fixed with several baffle plates on the described chain belt;

Described two ratchets to rotate freely direction opposite, promptly one of them ratchet rotates freely along clockwise direction, must rotate with being set in its inner bearing in the counterclockwise direction; Another ratchet rotates freely in the counterclockwise direction, must rotate with being set in its inner bearing along clockwise direction;

Described two bearings that are separately positioned on two ratchet inside connect generator by two shaft joints respectively;

Described bearing is by the gear wheel reversing device, for alternator shaft provides one and the equidirectional moment of another bearing;

Described some baffle plates are vertically fixed on the chain belt.

A kind of wave water turbine that the utility model provides, be arranged on the longshore water surface, half is dipped in the seawater, the bottom that is described baffle plate is immersed in the seawater, utilize the back and forth movement of seawater, make that the bottom of baffle plate is stressed, drive the ratchet rotation by chain belt, one of them ratchet also drives connected bearing rotation simultaneously, provides dynamic power by shaft joint for generator.

A kind of wave water turbine that the utility model provides has solved the seawater back and forth movement, is subjected to the inconsistent problem of force direction, can both provide the power of a direction to generator no matter seawater still moves forward backward, makes generator can continue generating.

Description of drawings

Fig. 1 is the structural representation of a kind of wave water turbine provided by the utility model.

Concrete real-time mode

Followingly a kind of preferred implementation of the present utility model is described according to Fig. 1:

As shown in Figure 1, a kind of wave water turbine provided by the utility model comprises the ratchet 1 and the ratchet 2 that connect by chain belt 3, edge bearing 11 in the ratchet 1, and edge bearing 12 is fixed with several baffle plates 13 in the ratchet 2 on the chain belt 3;

Described ratchet 1 and ratchet 2 to rotate freely direction opposite, promptly ratchet 1 rotates freely along clockwise direction, in the counterclockwise direction must be with being set in its inner bearing 11 rotations; Ratchet 2 rotates freely in the counterclockwise direction, along clockwise direction must be with being set in its inner bearing 12 rotations;

The described bearing 11 that is arranged on ratchet 1 inside connects generator by shaft joint;

The described bearing 12 that is arranged on ratchet 2 inside also connects generator by shaft joint;

Described bearing 1 is by the gear wheel reversing device, for alternator shaft provides one and bearing 2 equidirectional moments;

Described bearing 2 also can be alternator shaft one and bearing 1 equidirectional moment is provided by the gear wheel reversing device;

Described some baffle plates 13 are vertically fixed on the chain belt 3.

In the present embodiment, because ratchet 1 clockwise direction can freely rotate, counter clockwise direction then drives bearing 11 rotations, and 2 on ratchet in contrast.When wave moves right, the bottom baffle plate is subjected to power to the right, chain belt 3 drives ratchet 1 and counterclockwise rotates, simultaneously also drive bearing 11 and rotate together, bearing 11 provides the moment of alternator shaft and bearing 12 same directions by the gear wheel reversing device, drive generator for electricity generation by shaft joint again, at this moment, because of ratchet 2 counterclockwise can freely rotate, then can not drive bearing 12 and rotate.

When wave during to left movement, the bottom baffle plate is subjected to power left, chain belt 3 drives ratchet 2 clockwise directions and rotates, simultaneously also drive bearing 12 and rotate together, bearing 12 provides the moment of alternator shaft and bearing 11 same directions by the gear wheel reversing device, drive generator for electricity generation by shaft joint again, at this moment, because of ratchet 1 clockwise direction can freely rotate, then can not drive bearing 11 and rotate.

A kind of wave water turbine that the utility model provides, solved the seawater back and forth movement, be subjected to the inconsistent problem that can not be used to generate electricity of force direction, can both provide the power of a direction to generator, make generator can continue generating no matter seawater still moves forward backward.

A kind of wave water turbine that the utility model provides, it is low also to have cost, applied range, the utilization ratio height, characteristics such as energy source clean, ocean wave energy goes round and begins again, inexhaustible, can develop into the important supplement energy that coastal area life, production and national defence need fully.
