Description

Wave-type electric generator

Technical field

The utility model relates to a kind of electricity generating device, especially a kind of device that utilizes ocean wave energy to generate electricity.

Background technique

Along with the development and the industrialized progress of society, energy problem has become a much-talked-about topic, and how to find a cleaning, green, total amount to enrich, obtain to be easy to novel energy is the problem that people need to be resolved hurrily always.Nowadays existing a lot of novel energies occur, as solar energy, wind energy, nuclear energy, wave energy etc., wherein wave energy is to be electric energy and a kind of energy of storing with fluctuate the up and down Conversion of energy that produces of seawater, existing wave-type electric generator mainly contains the corrugated and cuts down structures such as raft, float type oscillating water column type, current type, pressure flexible bag type, but the common problems that exist of these devices are wave energies, and to be converted into the medium tache of electric energy more, thereby cause energy transformation ratio low, the wave properties of electric power output is bigger, and this has seriously influenced wave-activated power generation and has developed on a large scale.

Summary of the invention

The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, and the Conversion of energy step is few, and the efficient height is convenient to realize the wave-type electric generator of extensive generating.

Concrete solution of the present utility model is: a kind of wave-type electric generator, comprise float 1, it is characterized in that: vertically offer through hole 2 on the described float 1, be provided with slideway 3 in the through hole 2, the both sides of the moving mass 4 that matches with through hole 2 are provided with the raised line 5 that matches with slideway 3, on moving mass 4, be vertically arranged with tooth bar 6, the gear 7 that is meshed with tooth bar 6 is supported on the float 1, can contact with the piezoelectric crystal group 9 that is arranged on float 1 upper surface with the coaxial cam 8 of gear 7, piezoelectric crystal group 9 is communicated with the storage battery 10 that is arranged on float 1 inside.

Described cam 8 is a plurality of, and is the axisymmetric setting with tooth bar 6.

The utility model is compared with prior art, has following advantage:

This device simple in structure, design ingenious, novel, it is by simple mechanical structure, the unsteady straight line motion up and down that is produced of wave is converted into the rotation of gear, utilize gear to rotate the drive cam then the piezoelectric crystal group is exerted pressure, and piezoelectric crystal is under pressure the back electrical power storage that produces in storage battery; Because the medium tache of this Conversion of energy is less, so its energy transformation ratio is comparatively desirable, is suitable for generating electricity on a large scale.

Description of drawings

Fig. 1 is the utility model embodiment's a structural representation.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of wave-type electric generator, comprise float 1, on float 1, vertically offer through hole 2, in through hole 2, be provided with slideway 3, is furnished with moving mass 4 mutually with through hole 2, also be respectively arranged with the raised line 5 that matches with slideway 3 in the both sides of moving mass 4, under the effect of slideway 3 and raised line 5, moving mass 4 can be made straight line motion longitudinally in through hole 2; On moving mass 4, also be vertically arranged with tooth bar 6, gear 7 rotational support that are meshed with tooth bar 6 are on float 1, the cam 8 coaxial with gear 7 is positioned at piezoelectric crystal group 9 tops that are arranged on float 1 surface, like this when cam 8 rotates, can contact with piezoelectric crystal group 9, and piezoelectric crystal group 9 is communicated with the storage battery 10 that is arranged on float 1 inside.

The working procedure of the utility model embodiment's wave-type electric generator is as follows: float 1 bottom at this device is provided with a connecting rope, the other end of this connecting rope is fixed on seabed (by hanging the mode of weight), when wave moves upward, float can't move upward under the pulling effect of rope, 4 of moving mass move upward under the effect of wave, this hour rack 6 and gear 7 relative movement, gear 7 rotates, and drive cam 8 is done swing, the protuberance branch of cam 8 is pressed on the piezoelectric crystal group 9, and the power delivery that piezoelectric crystal group 9 produces stores in storage battery 10; When wave moved downward, moving mass 4 moved downward with respect to float 1, and above-mentioned action reversed is carried out, and cam 8 disengagings contact with piezoelectric crystal group 9, wait for wave next time; When wave moved upward again, cam 8 contacted with piezoelectric crystal group 9 equally again, produced electric energy.

So repeatedly, realize wave energy is converted into the purpose of electric energy.

For the conversion ratio that makes energy is higher, cam 8 can be provided with a plurality of, and is the axisymmetric setting with tooth bar 6, and in the movement process that so once generates electricity, pressure is born in a plurality of positions of piezoelectric crystal group 9, and the electric energy of conversion is also just more.

Claims
