Description
Technical field
The utility model relates to a kind of pushing-type Wave power generation device, belongs to power generating equipment technical field.
Background technique
In today of resource anxiety, the development and utilization of fossil energy brings serious environmental pollution problem, and stock number is declining day by day, and therefore ocean wave and tidal energy are as the reproducible clean energy resource of one, have progressed into the visual field of people.Investigation according to world energy sources ATSC Advanced Television Systems Committee shows, and global available wave energy reaches 2,000,000,000 KW, is equivalent to 2 times of current world generated energy, and the wave energy resource of China Coast is approximately 7,060,000 KW according to statistics, and therefore the exploitation of wave energy has great importance.
The key of wave power utilization is Wave energy converting device and Wave power generation device, current Wave power generation device, subject matter is complex structure, manufacture cost is high, and Wave power generation device exists the problem of inefficiency for the conversion of Wave energy, make Wave power generation device cannot reach the object of business application.
Model utility content
The utility model object is to provide a kind of pushing-type Wave power generation device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pushing-type Wave power generation device, comprises a push rod, screw rod, core bar, bull stick, unilateral bearing and generator; One end of described screw rod is fixed on described push rod, and described core bar is set on described screw rod; The inner ring of described core bar and described unilateral bearing is affixed, and the outer ring of described bull stick and described unilateral bearing is affixed; Rotor and the described bull stick of described generator are in transmission connection.
Preferred technological scheme is: described bull stick is provided with flywheel.
Preferred technological scheme is: the sectional shape of described screw rod is rectangle, offers the spirality through hole that sectional shape is rectangle in described core bar.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
1, structure of the present utility model is only made up of push rod, screw rod, core bar, bull stick, unilateral bearing and generator, therefore has structure simple, the advantage of low cost of manufacture.
2, the utility model is by changing the rotation becoming bull stick by the straight line motion of screw rod, and improve stability, energy conversion rate is high.
Accompanying drawing explanation
Accompanying drawing 1 is Wave power generation device schematic diagram.
In above accompanying drawing, 1, float; 2, push rod; 3, screw rod; 4, core bar; 5, bull stick; 6, unilateral bearing; 7, flywheel.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Notice, structure, ratio, size etc. that this specification institute accompanying drawings illustrates, content all only in order to coordinate specification to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this specification as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
Embodiment: a kind of pushing-type Wave power generation device
Shown in accompanying drawing 1, a kind of pushing-type Wave power generation device, comprises a push rod 2, screw rod 3, core bar 4, bull stick 5, unilateral bearing 6 and generator; One end of described screw rod 3 is fixed on described push rod 2, and described core bar 4 is set on described screw rod 3; Described core bar 4 is affixed with the inner ring of described unilateral bearing 6, and described bull stick 5 is affixed with the outer ring of described unilateral bearing 6; Rotor and the described bull stick 5 of described generator are in transmission connection.Push rod 2 and bull stick 5 are hollow structure, push rod 2 is set on bull stick 5, one end of screw rod 3 is fixed on push rod 2 inside, the metal twisting that screw rod 3 is rectangle by sectional shape forms, in order to the form fit with screw rod 3, offer the spirality through hole that sectional shape is rectangle in described core bar 4, like this core bar 4 is enclosed within screw rod 3.The bull stick 5 of hollow structure is enclosed within core bar 4, and the inner side surface of the hollow structure of bull stick 5 is connected by unilateral bearing 6 with the outer side surface of core bar 4.The effect of unilateral bearing 6 is: when push rod 2 moves to generator direction, locked because of unilateral bearing 6, and make not carry out between core bar 4 and bull stick 5 relatively rotating and driving bull stick 5 to rotate by core bar 4, when push rod 2 deviate from generator move time, then relatively rotate between core bar 4 and bull stick 5, so then allow that screw rod 3 is extracted out from core bar 4.When Wave power generation device runs, because generator position is fixed, float 1 position is not fixed, and therefore push rod 1 and screw rod 3 are subjected to displacement, and bull stick 5 only rotates in original place.
In order to be used for reducing the speed fluctuation in bull stick 5 rotation process, be preferred embodiment: at bull stick 5, flywheel 7 is set.
When installing Wave power generation device, generally will first be fixedly installed by generator, in water, then arrange a float 1, this float 1 is positioned in water in whole or in part.Float 1 and push rod 2 one are fixed, after float 1 receives the thrust of wave, push rod 2 is driven to move together, the screw rod of end winding support on push rod 23 is correspondingly along with there is straight-line displacement in push rod 2, the straight line of push rod 2 is positioned at, and drives the core bar 4 be enclosed within push rod 2 to rotate, the structural feature of the rotation recycling unilateral bearing 6 of core bar 4, drives bull stick 5 to rotate, the rotor turns of bull stick 5 then drive electrical generators.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
