Abstract
The invention discloses a pressure power generation device for a ship body. The device comprises a balance beam mechanism and the pressure power generation device arranged on the ship body, wherein the balance beam mechanism comprises a middle supporting frame and at least a balance rod hinged on the supporting frame in the middle. Heavy hammers are arranged at both ends of the balance rod. The pressure power generation device comprises a piezoelectric material layer, a lead and a storage battery, wherein the piezoelectric material layer is located below the heavy hammers and is sequentially connected with a bridge rectifier, a voltage stabilizer and the storage battery through the lead. The device disclosed by the invention is arranged on the ship body, and the balance rod swings left and right through swing of the ship body in water, so that the heavy hammers move up and down continuously to apply pressure to the piezoelectric material layer so as to generate electric energy. The device disclosed by the invention is simple in structure, and the device for power generation on the ship body is suitable for fishermen living on water for a long time and survivors of marine perils, so that the device is a green and environment-friendly clean energy source.
Description
Technical field
The present invention relates to the pressure electricity-generating field, relate in particular to a kind of pressure generating set for hull.
Background technology
Piezoelectric effect is that piezoelectric is exerted pressure, and its surface produces electric charge, and the quantity of electric charge of generation is directly proportional with pressure, is referred to as direct piezoelectric effect; Otherwise apply voltage, will produce mechanical stress, be referred to as inverse piezoelectric effect.Piezoelectric has very high energy density, and peak value reaches 100～10000Kw/Kg, has applied to many fields by pressure electricity-generating.For example CN101873081B discloses a kind of pressure power-generating system for bus.Piezoelectric under pressure upper and lower surface produces electric charge, and piezoelectric element is equivalent to an electric capacity, can be reduced to a sinusoidal current source, with the electrode capacitance C of inherence
pParallel connection is respectively at electric charge and the voltage of extraneous pressure-acting lower piezoelectric material production:

In the formula: d
33Piezoelectric constant for piezoelectric; F is the stress that acts on piezoelectric material surface; A
FpApply the area in zone for active force; C
pBe the piezoelectric equivalent capacity, by formula as can be known, electric charge and voltage that piezoelectric produces are directly proportional with its suffered pressure and area.
Hull is waterborne owing to being positioned at, can not be steady as on the ground, but rock along with the fluctuation of the water surface.Can but this energy that rocks generation not also be utilized fully, especially meets with the lifeboat of the perils of the sea, utilize the existing energy to generate electricity, and just seems particularly important.
Summary of the invention
The purpose of this invention is to provide a kind of pressure generating set that is used for hull that can generate electricity by pressure.
For addressing the above problem, a kind of pressure generating set for hull of the present invention, comprise the balance beam mechanism and the pressure generating set that are arranged on the hull, this balance beam mechanism comprises that bracing frame in the middle of being positioned at and at least one middle part are hinged on the balancing pole on the bracing frame, and the two ends of described balancing pole are provided with executes weight; Described pressure generating set comprises piezoelectric material layer, wire and storage battery, and described piezoelectric material layer is positioned at executes the weight below, and piezoelectric material layer links to each other with bridge rectifier, pressurizer and storage battery successively by wire.
Described piezoelectric material layer below also is provided with Compress Spring.
A kind of pressure generating set for hull of the present invention is arranged on the hull, utilizes hull rocking on the water, and the balancing pole in the balance beam mechanism is vacillated now to the left, now to the right, and constantly moves up and down thereby execute weight, piezoelectric material layer is exerted pressure, thereby produce electric energy.The present invention is simple in structure, is used for the hull generating, is fit to the fisherman of long-term inhabitation waterborne, the survivor of the generation perils of the sea, is the clean energy resource of environmental protection.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
In order to make those skilled in the art person understand better technical solution of the present invention, the present invention is described in further detail below in conjunction with drawings and embodiments.
As shown in the figure, a kind of pressure generating set for hull of the present invention, comprise the balance beam mechanism and the pressure generating set that are arranged on the hull, this balance beam mechanism comprises that bracing frame 11 in the middle of being positioned at and at least one middle part are hinged on the balancing pole 12 on the bracing frame, and the two ends of described balancing pole 12 are provided with executes weight 13; Described pressure generating set comprises piezoelectric material layer 21, wire and storage battery, and described piezoelectric material layer 21 is positioned at executes weight 13 belows, and piezoelectric material layer 21 links to each other with bridge rectifier, pressurizer and storage battery successively by wire.
Described piezoelectric material layer below 21 also is provided with Compress Spring 22.When pressure disappeared, the power that back-moving spring 22 makes progress for piezoelectric material layer 21 can quickly recover to the front state of pressurized.Back-moving spring 22 also plays the effect of damping.
A kind of pressure generating set for hull of the present invention is arranged on the hull, utilizes hull rocking on the water, and the balancing pole in the balance beam mechanism is vacillated now to the left, now to the right, and constantly moves up and down thereby execute weight, piezoelectric material layer is exerted pressure, thereby produce electric energy.The present invention is simple in structure, is used for the hull generating, is fit to the fisherman of long-term inhabitation waterborne, the survivor of the generation perils of the sea, is the clean energy resource of environmental protection.
