Wherein, 2 hydraulic bags 13 have certain toughness and elasticity, lay respectively at forefoot and the rear heel position of sole, inside store liquid, and distortion under applied external force extruding, discharges internal liquid, human foot is trampled the kinetic energy that conversion of motion is liquid.Human foot is trampled motion and is had the characteristic that displacement is little, momentum is large, directly utilize the mechanical energy of this motion to carry out generating difficulty larger, the present invention adopts the form of hydraulic bag, the foot mechanical movement of vertical direction is converted to the kinetic energy being easy to the liquid collected flowed in the duct, transformation efficiency is high, can make full use of the energy that human body tramples generation.Hydraulic bag 13 can select elastomeric material, and it possesses certain elasticity and intensity, and waterproof is cheap, and sole environment can not be subject to irradiation and the corrosiveness of sunlight, less demanding to corrosion resistance.The feature can advanced according to human body, is designed to ellipsoid by hydraulic bag 13, is convenient to liquid flowing under extrusion, improves liquid flow rate, and then improves generating efficiency.
In order to improve the outlet kinetic energy of liquid, by hydraulic bag outlet extending, form the flexible pipe with certain length, the diameter of flexible pipe 12 and motor inlet diameter matches, can water conservancy diversion be played and improve the effect of liquid rate, under identical extruding force effect, the kinetic energy of liquid increases, and then can improve generating efficiency.
In human body traveling process, two hydraulic bags are alternately extruded, and the liquid in hydraulic bag is constantly extruded and flowed back under the driving of external force, and fluid generator usually used is unidirectional, energy utilized for this reciprocating liquid is less, and generating efficiency is also relatively low.So for the less apparatus of the present invention of system scale, select a kind of structure that can utilize the kinetic energy of fluid in the two directions with higher efficiency, improve the flux change rate in the coil groups in magnetic flux in generator coil group and motion process as much as possible, for raising generated output and generating efficiency very important.Again because this small generator is installed in sole, certain pressure can be born in the process of normal work, and its inside is provided with the parts such as impeller, coil, magnet, brush, so need shell mechanism to protect inner part with enough intensity.The impeller of generator needs to be operated in liquid environment, so the generator in Blast Furnace Top Gas Recovery Turbine Unit (TRT) of the present invention is inside and outside double-layer structure.The two ends of shell body 1 are connected with the exit seal of 2 hydraulic bags 13; Inner housing 2 is fixedly mounted on the inside of shell body 1; It is the path of liquid between shell body 1 and inner housing 2; 2 impellers 7 are oppositely arranged on the two ends of inner housing 2, in the fluid path between shell body 1 and inner housing 2, for being the rotation momentum of impeller by liquid kinetic transformation; Magnet group 3 and coil groups 4 are arranged on the inside of inner housing 2, and respectively at the impeller shaft 5 of 2 impellers 7,6 are fixedly connected with, when being subject to the impact from the liquid of any one end, two impellers 7 installed on the contrary can rotate all the time in the opposite direction, thus drive magnet group 3 and coil groups 4 to rotate with contrary direction.Relative to the stator rotor structure of conventional electric generators, dual-rotor structure further can improve the relative motion between magnet group and coil groups, also can utilize better in human body traveling process the alternately extruding of 2 hydraulic bags simultaneously, the feature of liquid bidirectional flowing, thus the flux change rate in raising coil, improve generating efficiency.
Wherein, shell body 1 mainly plays the function of protection inner member and structure; need the larger impact force action that can prevent trampling of intensity on the part of electrification structure inside, again because shell will be arranged in footwear, so the weight of crust of the device overweightly should not affect human motion; and in operational environment, have the existence of water; so material must can not by aqueous corrosion, and shell body 1 can not conduct electricity, therefore; shell body 1 should be made up of high, the lightweight electrically non-conductive material of a kind of intensity, such as rigid plastics.
Shell body also will bear the function connecting to introduce liquid with hydraulic bag 13 simultaneously, the part that shell body 1 rear and front end connects with hydraulic bag 13 is carved with screw thread to seal, and, the end face of shell body 1 rear and front end is provided with water in-out port 19, as shown in Figure 4, water in-out port 19 is symmetrical circular arc, is conducive to by liquid guide flow on the blade of impeller 7, reduces energy loss.
In addition, shell body 1 also will possess the function of the electric energy output produced by generator, if adopt wire to draw from shell, liquid between shell body and inner housing is easy to reveal, so adopt output electrode as the interface outwardly exporting electric energy, the both sides at the middle part of the shell body 1 shared with shell body 1 at inner housing 2 are respectively equipped with output electrode 9, wherein, the good copper sheet of conductibility can be adopted as output electrode.
Inner housing 2 is airtight cavity, is become, be fixedly mounted on the inside of shell body 1, be fixedly mounted on the inside of shell body 1 by two vertical intersecting shape of cylindrical housings, and crossing with the middle part of shell body 1, with the middle part of shell body 1 common enclosure body 1, as shown in Figure 3.The function of inner housing 2 is parts such as coil groups, magnet group of its inside of protection, and the space between inner housing 2 and shell body 1 is the flow passage of liquid.Inner housing 2 inside is installed with bearing, and magnet group 3 and coil groups 4 are fixedly mounted on inner bearing and outer bearing respectively; Inner housing 2 with the intersection of shell body 1 arrange output electrode 9.According to the analysis of shell body 1 material, the material of inner housing 2 can be identical with shell body 1 material.
Impeller 7 is the device of the mechanical energy kinetic energy of liquid being converted to rotation.In order to realize two-way generating, 2 impellers 7 are oppositely arranged on the two ends of generator internal layer shell 2.The axle (impeller shaft 6) of 2 impellers 7 is fixedly connected with coil groups 4 with the magnet group 3 being arranged on inner housing 2 inside respectively.When the liquid entered from any side impacts the impeller at two ends successively, two impellers start to rotate with contrary direction, drive magnet group and coil groups to rotate in the opposite direction respectively, produce electric energy.Impeller adopts rigid plastics namely can complete function preferably by lower cost equally.
The magnet of magnet group 3 is the source producing magnetic flux, and the magnetic force of magnet is stronger, and so the rate of change of magnetic flux is larger; Meanwhile, magnet volume is smaller, could form array like this and put into footwear.Current ferromagnetic material mainly contains ferrite, neodymium iron boron, SmCo and aluminium nickel cobalt.Wherein ferritic performance low and in, price is minimum, and temperature characterisitic is good, corrosion-resistant, and the ratio of performance to price is good; Neodymium iron boron performance is the highest, and in price, intensity is good, non-refractory and corrosion; The performance of SmCo is high, and price is the highest, crisp, and temperature characterisitic is excellent, corrosion-resistant; Aluminium nickel cobalt performance is low, and in price, temperature characterisitic is excellent, and corrosion-resistant, resistance to interference is poor.Consider the application in footwear, very not high requirement to temperature performance and decay resistance, and requires better performances, therefore select the magnet of this material of neodymium iron boron.

Field effect transistor (MOSFET) is voltage driven type switching device, its gate pole as control end input internal resistance is very large, is equivalent to open circuit, can not consumes too many power, therefore in order to improve the efficiency of system, the switching tube adopting MOSFET as controlling circuit of voltage regulation is selected.Voltage stabilizing circuit adopts push-pull type working method, makes two MOSFET alternate conduction, by realizing the output of electric energy to the charging of inductance and the electric discharge of inductance, and regulates according to feedback, ensures the stable of output voltage.
Due to people when walking, the extruding of foot to hydraulic bag is not coherent, and the energy that produces so foot mechanical energy generates electricity is also uneven, and the impact by human motion situation is very large.Therefore must collect the small energy of the pulsation that pin is each time trampled, and need to utilize energy storage device to walk at each the storage that the energy that produces continues to this mechanical energy Blast Furnace Top Gas Recovery Turbine Unit (TRT).Select ultracapacitor as memory module in the present invention.Ultracapacitor applicability is comparatively strong, lower to the requirement of circuit, and does not need to arrange special charging control circuit and charge/discharge control circuit.Due to it, to have charging rate fast, and power density is large, long service life, can not be subject to the feature such as impact of overcharge, overdischarge service time, so select ultracapacitor as energy storage module of the present invention.
