Abstract
The utility model relates to a power generating device for absorbing noise. The power generating device comprises a bottommost rotating disc, a supporting frame, a pivot which can move back and forth on the supporting frame, and a trumpet-shaped noise receiver on the topmost of the supporting frame. A sound-electricity converter is arranged on the right center of the noise receiver. The supporting frame is provided with a power conditioning device. The back of the supporting frame is provided with an electric energy storage device. The sound-electricity converter is arranged in a honeycomb shape and comprises a Helmholtz resonator and PVDF piezoelectric films. The PVDF piezoelectric films are arranged behind the Helmholtz resonator. The Helmholtz resonator and the parallel connected PVDF piezoelectric films are fixed on the noise receiver by a set of PBT polybutylene telephthalate clamping grooves. Signals of the PVDF piezoelectric films are sent to the power conditioning device and processed, and then electric energy is stored in the electric energy storage device. The generated electric energy can be provided for low-power lighting and supplying power for low-power loads after electric energy is rectified, converted and stored so that the power generating device for absorbing noise is suitable for occasions like a KTV, a bar, a highway, an airport, etc. and thus noise is changed into valuables.
Description
Technical field
The utility model relates to a kind of energy source device, particularly a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) that absorbs noise.
Background technology
In our life, sound is arranged, and some noises bring harm to us especially everywhere, such as the roar of millwork; Construction site iron hammer tap-tap, while especially taking off and the noise of highway both sides.People are actively weakening, and have but ignored the existing huge energy of noise itself in the time of shielding noise.How effectively to utilize these noises, they are turned waste into wealth, become the mankind for we are used and be devoted to the new direction of studying.
Summary of the invention
The utility model is for noise, harm to be arranged but be simultaneously also the problem of energy, has proposed a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) that absorbs noise, realizes absorbing the noise generating.
The technical solution of the utility model is: a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) that absorbs noise, the rotating disk that comprises bottommost, support, moving fulcrum before and after on support, the uppermost horn-like noise receiver of support, acoustical-electrical transducer is positioned at the center of noise receiver, the power conditioner is arranged in support, support has electric energy accumulator behind, acoustical-electrical transducer is honeycomb arrangement, comprise Helmholtz resonator, the PVDF piezoelectric membrane, the PVDF piezoelectric membrane is after Helmholtz resonator, Helmholtz resonator and PVDF piezoelectric membrane in parallel are fixed on the noise receiver by a set of PBT polybutylene terephthalate (PBT) draw-in groove, PVDF piezoelectric membrane signal send into the power conditioner and process after by electrical power storage in electric energy accumulator.
Described PVDF piezoelectric membrane is formed in parallel by the PVDF piezoelectric membrane of double-deck 30 μ m.
Described power conditioner comprises
threevoltage doubling rectifing circuit and MAX1672DC-DC conversion chip, PVDF piezoelectric membrane output current process
threeafter voltage doubling rectifing circuit and MAX1672DC-DC conversion chip, by wire by electrical power storage to the lithium battery in electric energy accumulator.
The beneficial effects of the utility model are: the utility model absorbs the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of noise, and the electric energy produced can provide the power supply of small-power illumination and low-power load etc. after transforming and store by rectification.Be applicable to KTV, bar, highway, the places such as airport, turn waste into wealth noise.
The accompanying drawing explanation
Fig. 1 is the generating device structure schematic diagram that the utility model absorbs noise;
Fig. 2 is the Blast Furnace Top Gas Recovery Turbine Unit (TRT) left view that the utility model absorbs noise;
Acoustical-electrical transducer structural representation in the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that Fig. 3 is the utility model absorption noise;
Power conditioner circuit theory diagrams in the Blast Furnace Top Gas Recovery Turbine Unit (TRT) that Fig. 4 is the utility model absorption noise.
Embodiment
Absorb as shown in Figure 1, 2 generating device structure schematic diagram and the left view of noise, whole device is provided with 360 degree rotating disks 2 of a front and back moving fulcrum 4 and bottommost, be convenient to regulate the sound wave received from different directions, uppermost noise receiver 3 is designed to horn-like, and design more is conducive to the collection to sound wave like this.Acoustical-electrical transducer 6 is positioned at the center of noise receiver 3, and power conditioner 1 is arranged in support, and support has electric energy accumulator 5 behind.
Acoustical-electrical transducer structural representation as shown in Figure 3, the shape of acoustical-electrical transducer 6 is designed to honeycomb arrangement, comprises Helmholtz resonator 8, PVDF piezoelectric membrane 9 in parallel, and PVDF piezoelectric membrane 9 in parallel is after Helmholtz resonator 8.Helmholtz resonator 8, PVDF piezoelectric membrane 9 in parallel are to be fixed in the rear portion of noise receiver 3 by a set of PBT polybutylene terephthalate (PBT) draw-in groove 7, the two ends of PVDF piezoelectric membrane 9 are drawn with wire 10, and be connected in parallel with other several pieces PVDF piezoelectric membrane 9 use wires in parallel, finally be connected on power conditioner 1, power conditioner 1 output is connected with electric energy accumulator 5 with wire.
Noise in noise receiver 3 collection environment, noise transfer strengthens noise vibration to Helmholtz resonator 8 by resonance, strengthened noise produces vibration at PVDF piezoelectric membrane 9, PVDF piezoelectric membrane 9 by piezoelectric activity on two surfaces along with the generation of vibration equal and opposite in direction, be delivered to power conditioner 1 by wire after opposite polarity electric charge, power conditioner circuit theory diagrams as shown in Figure 4, the electric current process
threeafter voltage doubling rectifing circuit and MAX1672DC-DC conversion chip, by wire by electrical power storage to the lithium battery in electric energy accumulator 5.
The absorption of noise frequency range is 60Hz850Hz.
The PVDF piezoelectric membrane that the PVDF piezoelectric membrane is double-deck 30 μ m is formed in parallel, long is 270mm, wide is 200mm, the electric energy of PVDF piezoelectric membrane Q output in parallel converts noisy alternating current to direct current after voltage tripler rectifier circuit D, then through MAX1672DC-DC conversion chip M, lithium battery C voltage stabilizing is charged.
