Description
Technical field
The invention belongs to new forms of energy and technical field of power generation, be specifically related to the spacing circular piezoelectric oscillator of a kind of manual push type sphere Blast Furnace Top Gas Recovery Turbine Unit (TRT), be used for the power supply of lamp remote-control device or remote control switch.
Background technology
The switch control of lighting is that any family and office space are all indispensable.Traditional fixed lamp switch connects with light fixture by lead, because of need connect up within the walls, so building is difficult to change after determining with decoration cost height and position.In recent years, along with the popularization and application of combination lamp, lamp switch also progressively by wall mounted formula switch in the past to portable or packaged type remote controller transition.Present lamp remote-control device is substantially all battery-powered, can't use when battery power exhausts, and waste battery also can cause serious environmental to pollute and the wasting of resources simultaneously.For this reason, people have successively proposed based on electromagnetic power generation apparatus, as Chinese patent 201020190448.1,200920003419.7 and 01255765.X etc., or the remote switch for lamps of piezoelectric generating device power supply.The energy conversion efficiency of electromagnetic power generation apparatus is higher relatively, but can produce electromagnetic interference in power generation process, and then influences the reliability and the accuracy of remote controller.By comparison, piezoelectric generating device utilizes the flexural deformation of sheet type piezoelectric vibrator to convert mechanical energy to electric energy, have simple in structure, cost is low and power generation process in piezoelectric vibrator do not generate heat, do not produce characteristics such as electromagnetic interference.
Utilizing aspect piezoelectric generating device structure electric non-battery remote controller or the remote control switch, domestic existing more patent application, Chinese patent 200520111441.5 and 00817016.9 has been introduced two kinds of piezoelectric generating devices based on strike/bump mode respectively, and Chinese invention patent 200520008424.9 has been introduced a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) and remote controller thereof that utilizes button for the piezoelectric element application of force.Above-mentioned patent all is to utilize 1 piezoelectric vibrator, its generating operation energy output can't satisfy the power demand of remote controller emission system at all, and can only adopt repeatedly the method for electrification energy storage to power, do not meet the operating habit of remote controller, especially fixed lamp switch.Therefore, the inventor had once proposed the remote controller of two kinds of dial type piezoelectric self-powersupplies: Chinese invention patent 200810051579.9,200810051157.1, but Development Practice subsequently shows, the generating operation scheme of above-mentioned self-powered remote controller is difficult to realize: the button of patent 200810051579.9 can't be stirred piezoelectric vibrator reliably because of the guide and limit that lacks necessity and reset smoothly, and reliability is relatively poor; Patent 200810051157.1 and 200820072434.2 is stirred cantilever beam piezoelectric vibrators by rotating moving tooth, its structure and motion process complexity, and small fretting wear can cause moving tooth to lose efficacy, and manufacturing cost is higher.Deficiency at above-mentioned dial type piezoelectric generating device, the inventor proposes a kind of new dial type Blast Furnace Top Gas Recovery Turbine Unit (TRT) once more: Chinese patent 201010165882.9, practice shows, this structure Blast Furnace Top Gas Recovery Turbine Unit (TRT) is easy to processing and fabricating, also can produces enough electric energy, weak point is the control that is difficult to realize a plurality of light fixtures: can't establish a plurality of buttons, a switch only can be controlled a lamp, and the problem that exists campaign-styled trigger mechanism parts to lose efficacy because of fretting wear equally.In addition, in the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of above-mentioned all cantilever beam piezoelectric vibrators, only produce in the longitudinal direction after the piezoelectric vibrator free end is stressed and do not have distortion on flexural deformation, the Width, stress does not change, therefore the energy output when piezoelectric vibrator area and thickness are identical is far below the energy output of circular piezoelectric oscillator, the circular piezoelectric oscillator radially and tangentially STRESS VARIATION is arranged all, so generating capacity is strong; And the dial type Blast Furnace Top Gas Recovery Turbine Unit (TRT) easily produces fatigue damage when also producing vibrating noise, piezoelectric vibrator dynamic duty in operating process.
Summary of the invention
The invention provides the spacing circular piezoelectric oscillator of a kind of sphere Blast Furnace Top Gas Recovery Turbine Unit (TRT), be used for remote controller power supply, with solve existing remote controller with piezoelectric generating device because of generating capacity a little less than, to operate inconvenience or unreasonable structure etc. former thereby problem such as be difficult to apply.
The technical solution used in the present invention is: the upper shell end is provided with the bearing that connects bearing pin, is used for mounting circuit boards, circuit board by screw to bearing, inside is equipped with the circular piezoelectric oscillator and is used to make it to produce the diastrophic sphere guide vane end stop of going up of iso-curvature, and upper surface is equipped with shift knob; The lower house end is provided with engaging lug, inside is equipped with the circular piezoelectric oscillator and is used to make it to produce the diastrophic lower peripheral surface guide vane end stop of iso-curvature, ball is rotationally connected on the lower peripheral surface guide vane end stop, upper shell is hinged by the hole that is connected on bearing pin and the engaging lug with lower house, last sphere guide vane end stop and ball crimping.
The generating parts are the circular piezoelectric oscillator of two parallel connections, piezoelectric chip on the described piezoelectric vibrator is connected by lead group two respectively with metal substrate, link to each other with power circuit on the printed circuit board (PCB) through lead group one, this power circuit links to each other by the circuit of lead group three with shift knob and remote controller emission system more again.
In the present invention, upper shell, lower house, a pair of circular piezoelectric oscillator, two sphere guide vane end stops, one between last lower peripheral surface guide vane end stop ball and one group of button and the circuit board that is installed on the upper shell constitute Blast Furnace Top Gas Recovery Turbine Unit (TRT) jointly.When pressing described button, upper shell connected and drive by button and inner piezoelectric vibrator and sphere guide vane end stop rotates along the end bearing pin, and the effect of ball is upper shell to be rotated the pressure that is produced pass on the sphere guide vane end stop and piezoelectric vibrator that is arranged in lower house; With the lasting rotation of upper shell, two piezoelectric vibrators occur bending and deformation gradually, and finally are attached to sphere guide vane end stop surface, and this is a power generation process; Discharge button, after external force was removed, button disconnected, and piezoelectric vibrator recovers distortion and drive upper shell to return back to initial position in the effect of himself elastic force.
Characteristics of the present invention and advantage are:
Utilize the spacing flexural deformation that makes the circular piezoelectric oscillator produce the iso-curvature radius of sphere, the electric weight of suffered stress of its surperficial each point and generation is identical.When the suffered maximum stress of piezoelectric vibrator was identical, total energy output can improve more than 8 times, compare with piezoelectric vibrator center local compression, this moment piezoelectric vibrator pressurized place stress/energy output maximum and edge is 0;
The piezoelectric vibrator stress distribution was even when sphere was spacing, can avoid damaging because of local stress is excessive;
