Abstract
Provided is an acoustic vibration generating device. A sound wave transduction board which vibrates with the driving of sound waves is installed in a frame, an output connection piece at the center point of the sound wave transduction board is connected with a connection rod driving assembly composed of a lever and an adjusting spring, and the rear end of the lever is connected to an upper shaft of a magnetic resonance board. The direction of magnetic lines of force passing the magnetic resonance board is changed alternately to enable the magnetic lines to cut a generating coil to produce induction current.
Description
Technical field
The utility model relates to a kind of vibration that utilizes sound wave to produce, promote sound wave transducing plate and produce vibration, and convert the variation of magnetic line of force direction to, thereby make the vibration-magnetic line of force variation-power generation and conversion device of induction coil generating by sound wave transducing plate oscillation amplitude change.
Background technology
At present, known sound shake Blast Furnace Top Gas Recovery Turbine Unit (TRT) a kind of be acoustic energy to be converted to chemical energy store, convert electric energy to by chemical energy again; Another kind is that conduct vibrations is generated electricity to piezo ceramic element; Also having a kind of is to utilize acoustical vibration to drive a coil in Movement in Magnetic Field, produces induced current.First kind is the generating of vibration-chemical conversion in known the above Blast Furnace Top Gas Recovery Turbine Unit (TRT) of shaking; Second kind is that vibration-piezoelectric effect is sent pulse voltage, needs the pulse voltage change-over circuit, and the structure more complicated implements complex structure, is subjected to the restriction of coil weight volume, and it is very high that generating voltage and generation current can not be done, and efficient is lower.
Summary of the invention
In order to overcome the generating device structure complexity of shaking existing, implement relatively difficulty, the unfavorable situation of effect, the utility model provides the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of shaking a kind of, this Blast Furnace Top Gas Recovery Turbine Unit (TRT) of shaking does not need the relative motion of coil and magnet, only need the mechanical oscillation of sound wave transducing plate to be converted to motive force, make magnetic line of force reversal parts that corresponding the variation be taken place, in power coil, induce voltage with the lever drive system.Because coil does not move, so coil can be made bigger shape, conversion output voltage and output current ratio are easier to, and generating voltage is the interchange electrical waveform, conversion easily, transformation and output networking.The shape of sound wave transducing plate can make significantly billboard or screening sound plate edge-on near noise source, both sides such as highway, the noise of the noise of engine in the vehicle traveling process, tire scrape along the ground, the stormy waves of drive etc. are all converted to electric energy, be used for throwing light on or networking output, also shielded the propagation of noise simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is characterized in that: in framework, the sound wave transducing plate that installation is vibrated with the sound wave promotion, the output connector of sound wave transducing plate central point links to each other with the connecting rod transmission component that lever, regulating spring are formed, and the lever end is connected to magnetic vibration plate upper shaft.Jack shaft is equipped with at the middle part of magnetic vibration plate, is installed in the center of power coil.Between the S utmost point of its two ends of magnetic vibration plate and П type magnetic boots and the N vibration gap is arranged, П type magnetic boots are connected with permanent magnet by magnetic conductive board, and power coil is fixed on the П type magnetic boots.The S utmost point of its two ends of magnetic vibration plate and П type magnetic boots and the N utmost point constitute flux path, and П type magnetic boots are connected with permanent magnet by magnetic conductive board, and one is the N utmost point, and another is the S utmost point.When sound wave transducing plate is subjected to the vibration of sound wave, its amplitude changes, and transmission levers drives the magnetic vibration plate and vibrates in two П type magnetic boots gaps, makes the magnetic line of force direction generation alternate by the magnetic vibration plate, and the cutting power coil produces induced current.
The beneficial effects of the utility model are, can change into electric energy to the vibration of sound easily, and the acoustic-electric conversion adopts machine driving to be transformed into the mode that the magnetic line of force changes, and simple in structure, sending electric current is alternating current, can conveniently change and network.Cost is low.For example, when utilizing the noise generating, shielded noise, need not driven by energy just can generate electricity and throw light on, both protected environment, produced new forms of energy again in road both sides placement sound such as highway and the city's inner ring road Blast Furnace Top Gas Recovery Turbine Unit (TRT) of shaking.
