The lifeboat comprises boat bodies, wherein horizontal outward bulge parts and horizontal inward concave parts are uniformly arranged on the peripheries of the boat bodies, and the bulge parts and the concave parts are arranged in corresponding shapes and provided with locking structures, so that a plurality of lifeboats can be spliced with one another conveniently; pressure power generation devices are arranged inside cabins and comprise balance beam mechanisms and pressure power generation device bodies; each balance beam mechanism comprises a supporting frame located in the middle and at least one balance rod, the middle of the at least one balance rod is hinged to each supporting frame, and weighting hammers are arranged at two ends of each balance rod; and each pressure power generation device body comprises a piezoelectric material layer, a lead and a battery, and each piezoelectric material layer is located below each weighting hammer and connected with a bridge rectifier, a voltage stabilizer and each battery through each lead sequentially. The lifeboat is simple in structure, can generate electricity and is applicable to survivors suffering shipwrecks.
Description
Technical field
The utility model relates to the field of salvaging at sea, and relates in particular to a kind of lifeboat.
Background technology
Piezoeffect is that piezoelectric is exerted pressure, and its surface produces electric charge, and the quantity of electric charge of generation is directly proportional to pressure, is referred to as direct piezoelectric effect; Otherwise apply voltage, will produce mechanical strees, be referred to as inverse piezoelectric effect.Piezoelectric has very high energy density, and peak value reaches 100～10000Kw/Kg, by pressure electricity-generating, has applied to many fields.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 inherent electrode capacitance C
pparallel connection, is respectively at electric charge and the voltage of extraneous pressure-acting lower piezoelectric material production:

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.
Utility model content
The purpose of this utility model is to provide between a kind of hull and can mutually splices, and the lifeboat that can generate electricity by pressure.
For addressing the above problem, a kind of lifeboat of the present utility model, comprise hull, in hull, be provided with for manned upper strata cabin and for lower floor's cabin of loading, described hull periphery is evenly provided with lug boss and the inside depressed part of level horizontally outward, described lug boss and the corresponding setting of depressed part shape, and lug boss and depressed part be provided with buckle structure, so that a plurality of lifeboat can splice mutually; In described lower floor cabin, be provided with pressure generating set, this pressure generating set comprises balance beam mechanism and pressure generating set, this balance beam mechanism comprises that bracing frame and at least one middle part in the middle of being positioned at is hinged on the trammel beam on bracing frame, and the two ends of described trammel beam 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 weight below, and piezoelectric material layer is connected with bridge rectifier, voltage stabilizer and storage battery successively by wire.
Described piezoelectric material layer below is also provided with Compress Spring.
A kind of lifeboat of the present utility model, a plurality of hulls can splice mutually becomes a large ship, makes many people together, increase chances of survival; In cabin, be provided with pressure generating set, utilize hull on the water rock the trammel beam wigwag motion in ，Shi balance beam mechanism, thereby execute the continuous up-and-down movement of weight, piezoelectric material layer is exerted pressure, thereby produces electric energy.The utility model is simple in structure, and lifeboat can self generating, and the survivor who is applicable to occurring the perils of the sea uses.

Fig. 1 is the structural representation of a plurality of lifeboat splicing states of the present utility model.
Fig. 2 is the utility model cutaway view.
Fig. 3 is pressure generating set structural representation in the utility model.
The specific embodiment
In order to make those skilled in the art person understand better technical solutions of the utility model, below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in the figure, a kind of lifeboat of the present utility model, comprise hull 1, in hull, be provided with for manned upper strata cabin 2 and for lower floor's cabin 3 of loading, described hull 1 periphery is evenly provided with lug boss 101 and the inside depressed part 102 of level horizontally outward, described lug boss 101 and the corresponding setting of depressed part 102 shape, and lug boss and depressed part be provided with buckle structure, so that a plurality of lifeboat can splice mutually; In described lower floor cabin, be provided with pressure generating set, this pressure generating set comprises balance beam mechanism and pressure generating set, this balance beam mechanism comprises that bracing frame 11 and at least one middle part in the middle of being positioned at is hinged on the trammel beam 12 on bracing frame, and the two ends of described trammel beam 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 is connected with bridge rectifier, voltage stabilizer and storage battery successively by wire.
Described piezoelectric material layer below 21 is also provided with Compress Spring 22.When pressure disappears, the power that retracing spring 22 makes progress to piezoelectric material layer 21, can quickly recover to the state before pressurized.Retracing spring 22 also plays the effect of damping.
