[technical field]

The utility model relates to the wave-activated power generation unit.

[background technique]

Wave-activated generator is the novel electricity generator that a kind of potential energy that utilizes waves of seawater to rise and fall generates electricity, and is pollution-free in the power generation process because of it need not to consume other energy, can make full use of the natural resources the welcome of the dark many countries and regions of audient.But there is following defective in existing wave-activated generator: 1, can't all convert lumpy potential energy to electric energy, utilization ratio is lower; 2, development investment is big, complex structure and effect is bad, and maintenance cost is also high.

[model utility content]

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of utilization ratio height is provided, and generated energy is big, and cost is low, and it is little to consume energy, but the wave-activated power generation unit that large size is promoted.

The purpose of this utility model is achieved in that

The wave-activated power generation unit is characterized in that it comprises:

One rack shaft, this upper end and the buoyancy aid of a floatability on the water surface are rigidly connected, and can drive its upper and lower moving by buoyancy aid; The outer wall of rack shaft is provided with the tooth bar that is arranged above and below; Rack shaft also is the guide rail of mechanism's activity;

One counter weight device, inertia is big because its quality is big, is not easy to follow floating motion, thereby obtains the potential energy of wave;

One accelerating gear mechanism, it is fixed on the counter weight device, and its input end gear is connected with the tooth bar of rack shaft; Output terminal drives alternator shaft;

One generator, it is fixed in the counter weight device, and its output terminal with the accelerating gear group is connected;

One elastic component, the one end is connected with the upper end of rack shaft, and the other end is connected with counter weight device.

Aforesaid wave-activated power generation unit is characterized in that counter weight device comprises a staving and lid, and generator is fixed in the staving.

Aforesaid wave-activated power generation unit, it is characterized in that accelerating gear mechanism comprises the first accelerating gear group that is connected with the tooth bar of rack shaft, and the second accelerating gear group that is connected with the output terminal of the first accelerating gear group, second output wheel of the second accelerating gear group is connected with generator.

The utility model utilizes lumpy potential energy directly to change the kinetic energy of alternator shaft into, the potential energy of wave is by the variable in distance acquisition between the very big counter weight device of buoyancy aid that rises and falls and mass inertia, it is implicit and discharge that upper end by being connected rack shaft and the elastic component between the counter weight device transfer potential energy the potential energy of spring to, utilize accelerating gear mechanism that potential energy is become the kinetic energy of alternator shaft, thereby generate electricity; Counter weight device of the present utility model, elastic component, accelerating gear mechanism, generator are formed a moving body jointly; The utility model is fit to the wave-type electric generator of any watt level, but the large size popularization, and also the utilization ratio height, generated energy is big, and cost is low, and it is little to consume energy.
