The rotary type hand-operated piezoelectric generating device comprises a shell, a rotating shaft, cantilever beams, piezoelectric ceramic sheets, clamping rings, a handle, a connecting rod, a base and bearings, and two sides of the cantilever beams are both bonded with the piezoelectric ceramic sheets to form piezoelectric cantilever beams. The cantilever beam type piezoelectric generating device drives the rotating shaft to rotate via the rotation of the handle, a plurality of piezoelectric cantilever beams arranged along the radial direction of the rotating shaft are struck by projections of the shell with the driving of the rotating shaft so that the cantilever beams are enabled to vibrate, and the piezoelectric ceramic sheets pasted on the cantilever beams generate electricity due to the generation of piezoelectric effect. According to the rotary type hand-operated piezoelectric generating device, the plurality of cantilever beams are combined so that the mechanical energy generated by the rotation of the rotating shaft can be effectively converted to electric energy. The rotary type hand-operated piezoelectric generating device is advantaged by small size, high efficiency, convenient portability, wide application and the like.
Description
Technical field
The utility model relates to a kind of piezoelectric generating device, especially relates to a kind of rotating type manual piezoelectric generating device.
Background technology
Piezo-electric generating principle is to utilize the direct piezoelectric effect of piezoelectric, and, when piezoelectric is out of shape being subject to External Force Acting in a certain direction, its inner meeting produces polarization phenomena, there will be positive and negative contrary electric charge on its two apparent surfaces simultaneously.Piezoelectric is a kind of energy-conserving and environment-protective shaped material that relies on extraneous vibration that it is deformed and generate electricity, conventional piezoelectric Blast Furnace Top Gas Recovery Turbine Unit (TRT) is to utilize mechanical structure that extraneous vibration is applied to piezoelectric it is deformed and generate electricity, than electromagnetic power generation apparatus, simple in structure, the advantage such as volume is little, cost is low, environmental protection, electromagnetic-radiation-free that piezoelectric generating device has, its application is not subject to the restriction in place, do not need ad hoc place, and can meet the power requirement of low power consuming product and become one of focus of current research yet.But because its energy output is less, all the time, about how improving the generating capacity of piezoelectric generating device, become a key problem.In addition, although common, by magnetic, give birth to electric hand-operated power generator very ripe and be widely used, because of its complex structure, in the rotation process of rotor, its a large amount of mechanical energy that produce could not effectively be converted into electric energy, have caused a large amount of wastes of energy.The present invention has well solved the problems referred to above, Comparatively speaking simple in structure, transformation efficiency is high, and is easy to integrated.
Utility model content
The purpose of this utility model is to provide a kind of rotating type manual piezoelectric generating device, to solve the problems such as existing beam type piezoelectric generating device generating capacity is little, efficiency is low.
The utility model solves the problems of the technologies described above adopted technical scheme:
A kind of rotating type manual piezoelectric generating device of the present utility model, comprise shell, rotating shaft, cantilever beam, piezoelectric ceramic piece, clamp ring, handle, connecting rod, base, bearing, the both sides of described cantilever beam are all pasted described piezoelectric ceramic piece and are formed piezoelectric cantilever, it is characterized in that a plurality of described cantilever beams of radially installing along described rotating shaft are stirred and produce vibration by the projection on described shell under this rotating shaft drives, the described piezoelectric ceramic piece of pasting on this cantilever beam thereby direct piezoelectric effect occurs generate electricity.Described shell is provided with the projection that some equal angles distribute, and be arranged in rotating shaft by described clamp ring, the quantity of described cantilever beam is 1/2nd times of described protruding number, and described clamp ring is provided with several intermediate plates so that by screw cantilever mounted beam, and is connected with described rotating shaft by interference fit.Described a kind of rotating type manual piezoelectric generating device drives rotating shaft to rotate by rotary handle, cantilever beam is stirred and is made its vibration by the projection on shell, and then the generation of the piezoelectric ceramic piece on drive cantilever beam electric energy, the mechanical energy that the structure of a plurality of piezoelectric cantilevers just can be rotated rotating shaft be converted into electric energy efficiently.
The advantage of the utility model structure:
1, the mechanical energy that a plurality of cantilever beam structures can make this device efficiently rotating shaft be rotated is converted into electric energy, has higher generating efficiency.
