Embodiment
In order to clearer elaboration the purpose of this utility model, technical scheme and advantage, once in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.Should be appreciated that specific embodiment described herein only for explaining the utility model, instead of limit the utility model.
Fig. 1 is overall structure figure of the present utility model, mainly comprises Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20, Power Management Unit 30, key control switch 10, micro control unit 11 and rf transmitter unit 12.After control switch is pressed, after Blast Furnace Top Gas Recovery Turbine Unit (TRT) 20 produces electric energy, process through Power Management Unit 30, for micro control unit 11 and rf transmitter unit 12, launch a wireless control signal.After receiver receives this signal, control the switch of household electrical appliance.
Blast Furnace Top Gas Recovery Turbine Unit (TRT) of the present utility model as shown in Figure 2, comprises permanent magnet 1, soft magnetic material 2-1,2-2, filler 3, coil 4, iron core 5, elastic device 6.Permanent magnet and soft magnetic material connected mode have four kinds, respectively: 1, the end face of permanent magnet is connected with the side of soft magnetic material; 2, the end face of permanent magnet is connected with the end face of soft magnetic material; 3, the side of permanent magnet is connected with the side of soft magnetic material; 4, the side of permanent magnet is connected with the end face of soft magnetic material.Scheme 1 is other scheme comparatively, and comparatively side is strong for the end face magnetic of permanent magnet magnetism, and the side of soft magnetic material is larger compared with the contact-making surface of end face, and thus in scheme 1, soft magnetic material can be magnetized fully, best results.Need filling part filler 3 around the contacting of permanent magnet and soft magnetic material, form a smooth cuboid, permanent magnet can be prevented damaged so on the one hand, also be convenient to sliding up and down of magnet on the other hand.In sliding process, only have soft magnetic material to contact with iron core all the time, can prevent permanent magnet from frequently contacting with iron core and being worn, thus affect the life-span of permanent magnet.When gap is less, magnetic force is enough large and external force reaches requirement, generally can think that magnet only has two kinds with the relative position of iron core: 1, the soft magnetic material of magnet upper end contacts with iron core; 2, the soft magnetic material of magnet lower end contacts with iron core.In the state shown in Fig. 1, coil 4, iron core 5 are relative with elastic device 6 fixing, and under initial condition, the upper end soft magnetic material 2-1 of cuboid-type magnet contacts with iron core, and soft magnetic material 2-2 is unsettled in lower end.Under this state, iron core is by the magnet magnetization near S pole, and the magnetic induction line direction in coil 4 roughly as illustrated by the arrows in fig. 1.
Fig. 3 is under the effect of external force, and cuboid-type magnet moves downward, and the lower end soft magnetic material 2-2 of magnet contacts with iron core, and soft magnetic material 2-1 is unsettled in upper end.Now iron core is by the magnet magnetization near N pole, contrary just in time with Fig. 1 of the line of magnetic induction in coil 4, magnetic flux in such coil 4 there occurs larger change, according to electromagnetic induction principle, when the area of coil 4 is comparatively large, the number of turn is more, can produce a larger electric current, this electric current can be used for Micropower equipment to use after rectifying and voltage-stabilizing.Now, due to the deformation of elastic device 6, also store certain mechanical energy, after external force disappears, elastic device 6 can by cuboid-type magnet bullet to the position described in Fig. 1, and the line of magnetic induction direction in this process coil 4 changes again, the electric current that generation one is larger again.Visible, and do not have compared with elastic device 6, generating efficiency is doubled, but also makes device more send out assorted, in specific implementation process, can adjust according to actual conditions.
What be connected to Blast Furnace Top Gas Recovery Turbine Unit (TRT) rear stage is Power Management Unit, as shown in Figure 4.Power Management Unit gathers on the one hand, store the electric energy of self-generating device; On the other hand to being connected to the micro control unit of rear class, rf transmitter unit powers.Power Management Unit is formed primarily of rectification circuit, accumulator and voltage stabilizing circuit.The induced voltage that induction coil produces is alternating current, through bridge rectifier, accumulator is charged, last voltage stabilizing is necessary, and it can in the process of energy-storage travelling wave tube electric discharge, produces the constant voltage of short time and drives micro-control circuit below and radio frequency transmitter circuitry.Wherein, rectification circuit adopts full-wave rectification bridge.It is second half negative cycle that full-wave rectifying circuit changes all polarity in input waveform by diode, and pulsating nature is the half of half-wave rectifying circuit, and electric current is level and smooth, and rectification efficiency is two times of single phase half wave rectification.Also be worthy of careful study for choosing of rectifier diode, its forward conduction voltage is more low better, can reduce the loss of energy in switching process like this, improves conversion efficiency.Here can select Schottky diode, its forward conduction voltage is 0.3V.Energy-storage travelling wave tube adopts electrochemical capacitor, and it is a kind of energy-storage travelling wave tube of short-term, and the system be applicable to as instantaneous power is larger provides electric energy.Voltage stabilizing circuit, can adopt the ultra low differential pressure linear voltage stabilization chip of TI company, we can select TPS62231 here, and its transformation efficiency is up to 94%, and peripheral original paper is few, and start-up time is shorter, can be used for driving late-class circuit.
The signal controlling of afterbody, radiating circuit as shown in Figure 5, are mainly made up of microcontroller chip STM8L and radio-frequency transmissions chip CC1101.Their operating voltage is lower, and minimum operating voltage is only 1.8V, and both are by SPI communication, open and close that depresses button can be produced or dim signal passes to microcontroller chip, and then is sent out by signal by radio frequency chip and transmitting antenna.Here radio-frequency emission power is set to-10dBM, makes the operating current of chip when emission state reduce to 14mA like this, decrease the consumption of energy, ensure that stable the transmitting of energy at every turn, increase the reliability of self-power wireless reflector.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all make in spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection range of the present utility model.
