Background technique
With the development of wireless sensor technology and microelectric technique, wireless sensor has obtained great development.It is wireless to pass The powerup issue of sensor limits the development of sensor.Current wireless sensor exists in the way of battery powered to be needed often The problems such as replacement battery, maintenance cost is high, pollutes environment.Wind energy is renewable as one kind and is widely present in clear in nature The clean energy, has broad application prospects.Due to using wind energy piezoelectric type energy collector have structure it is simple, it is small in size, Output energy density is big, be easily integrated and the advantages that without electromagnetic interference, the wind energy collector based on piezoelectricity converts wind energy into electricity Can, for radio sensing network node energy supply relation technological researching more and more attention has been paid to.
According to retrieval, the related technology for carrying out wind collecting based on piezoelectric material existing at present occurs, such as Chinese patent Shen Please " a kind of piezoelectric energy collection method and device using wind energy " disclosed in number 201010516391.X, utilize wind to drive leaf Piece, the permanent magnet generation on blade produce electricl energy the repulsion of the fixed magnet on cantilever beam to make cantilever beam vibration, The device for mechanical structure is more complex, higher cost.For another example " based on flexibility disclosed in Chinese Patent Application No. 201610386604.3 The wind energy collector of polymer piezo material ", blade rotation drive turntable, and it is poly- that turntable rotation can periodically beat flexible piezoelectric Object cantilever beam is closed, piezoelectric membrane produces electricl energy in the vibration beaten and restore deformation, and the flexible piezoelectric material of the device is effective Deformation quantity is smaller, and generating efficiency is lower, and direct mechanism of the piezoelectric material face by turntable, and it is short that there are service lifes Disadvantage.
Therefore, it is necessary to propose that a kind of simple structure, at low cost, long service life and generating efficiency are high, it is suitable for miniature The novel piezoelectric Wind energy collecting device of sensor network nodes energy supply.
Summary of the invention
The object of the present invention is to provide a kind of novel piezoelectric Wind energy collecting device, its, uses simple, at low cost with structure Service life is long and the high advantage of generating efficiency.
The present invention reaches that the purpose is to be achieved through the following technical solutions:A kind of novel piezoelectric Wind energy collecting device, Including blade, shaft, pedestal, turntable, sliding block and flexible piezoelectric material etc..The shaft is fixedly mounted on by bearing and pedestal On, only one rotary freedom, shaft one end connects blade, and the other end connects turntable;Square is connected on the outside of the turntable Shape square bar is equipped with sliding block on square bar, and square bar tail end is fixed with limited block;Flexible piezoelectric material one end is connect with sliding block, One end is connect with turntable.Wind band movable vane piece rotates, and shaft passes motion to turntable, and when turntable rotates, sliding block has with respect to turntable Relative displacement, so that the deformation of flexible piezoelectric material be made to produce electricl energy.
The rod piece quantity of turntable connection can be it is multiple, the cross sectional shape of rod piece be can be rectangle, or triangle Shape, circle etc..The sliding block is rectangular ring body, and sliding block and rectangle stock cooperate.
The flexible piezoelectric material is retractable curved flexible piezoelectric material, and one end is fixedly connected with turntable, one end It is fixedly connected with a slide block.
Compared with prior art, the beneficial effects of the invention are as follows:
It is rotated by wind band movable vane piece, shaft communicates rotational motion to turntable, will using the relative motion of sliding block and turntable Wind energy is converted to potential variation, by changing the distance between two ends of flexible piezoelectric material, makes piezoelectric material that shape occur Become to produce electricl energy.It is compared with existing using flexible piezoelectric material progress wind collecting technology, the present invention only acts on The both ends of flexible piezoelectric material do not apply direct active force to flexible piezoelectric material surface, are conducive to extend making for piezoelectric material Use the service life;By reasonable design rod length, the variation of piezoelectric material both ends relative position is controlled, it is big that piezoelectric material may be implemented Amplitude deformation, generating efficiency are higher.The configuration of the present invention is simple, at low cost, long service life and generating efficiency are high, are suitable for miniature Sensor network nodes energy supply.

Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
A kind of novel piezoelectric Wind energy collecting device, including blade 1, shaft 2, pedestal 3, turntable 4, sliding block 7 and flexible piezoelectric Material 6 etc..The shaft 2 is fixedly mounted on by bearing on pedestal 3, only one rotary freedom, 2 one end of shaft connects Blade 1 is connect, the other end connects turntable 4;It is connected with rectangle square bar 5 on the outside of the turntable 4, sliding block 7, square bar 2 are installed on square bar 5 Tail end is fixed with limited block 8;Described 6 one end of flexible piezoelectric material is connect with sliding block 7, and one end is connect with turntable 4.Wind band movable vane piece 1 rotation, shaft 2 passes motion to turntable 4, and when turntable 4 rotates, sliding block 7 has relative displacement with respect to turntable 4, to make flexibility The deformation of piezoelectric material 6 produces electricl energy.
5 quantity of rod piece that the turntable 4 connects can be it is multiple, the cross sectional shape of rod piece 5 be can be rectangle, or three It is angular, circle etc..
The sliding block 7 is rectangular ring body, and sliding block 7 is coupled with rod piece 5.
The flexible piezoelectric material 6 is retractable curved flexible piezoelectric material, and one end is fixedly connected with turntable 4, one End is fixedly connected with sliding block 7.
The course of work and working principle of the invention:
The present apparatus is placed in the outdoor occasion for having wind, when wind acts on the device, wind band movable vane piece 1 is rotated, with blade 1 Fixed shaft 2 rotates synchronously, and fixed turntable 4 rotates with shaft 2, and when turntable 4 rotates, sliding block 7 is opposite with turntable 4 Position changes, and when sliding block 7 is at rotating distance lower half circumference, sliding block 7 is contacted with limited block 8, and turntable 4 continues to turn Dynamic, when sliding block 7 is at rotating distance upper semicircumference, sliding block 7 overcomes rotatory inertia centripetal force and contact friction force, along rod piece 5 It is snapped down to 4 direction of turntable and is contacted with turntable 4.Turntable 4 continues to rotate, when sliding block 7 is at rotating distance lower half circumference again, Sliding block 7 is snapped down to along rod piece 5 under the action of self gravity is with rotation centripetal force and contacts with limited block 8.In the whole process, sliding Block 7 and turntable 4 have biggish relative position to change, and since 6 one end of flexible piezoelectric material and sliding block 7 are fixed, one end and turntable 4 are solid Fixed, then the two of flexible piezoelectric material 6 end has biggish relative position to change, and deformation occurs for flexible piezoelectric material 6 therewith, leads to The piezoelectric effect for crossing piezoelectric material produces electricl energy.By rationally designing the length of rod piece 5, it can control 6 liang of flexible piezoelectric material The relative position of end changes size, piezoelectric material significantly deformation may be implemented, generating efficiency is higher.To realize to wind energy Highly effective gathering.
