Description

Micro-hydro generator

Technical field

The utility model is about a kind of micro-hydro generator, refers to that especially a kind of principle that utilizes water for producing electric power produces the device of voltage.

Background technique

The purpose of unit feeding water heater voltage of utilizing water for producing electric power is to exempt all maintenance works relevant with the power supply of water heater, if need periodic replacement portion product, just loses the meaning that electricity generating device is set.

TaiWan, China patent M393650 number " micro-hydro generator " of creator's application, utilize the water-driven water turbine of the gas heater water transport pipeline of flowing through just, drive generator by water turbine again and produce Ac, and behind rectifying and voltage-stabilizing, electronic ignition device power supply to water heater, reach and exempt the inconvenience of changing battery, reduce the consumption to natural resources simultaneously, and reduce the injury that environment is caused because use battery.

Produce the desired permanent magnet in magnetic field because the micro-hydro generator that above-mentioned patent discloses includes, and the water of the electricity generating device of flowing through there is the impurity of solid at least.The impurity of solid except entering with the water that flows into, also comprises the corrosion that pipeline itself causes, solid impurities such as these iron rust can be attracted the result who accumulates over a long period if do not remove in advance by magnet, can increase resistance or the pressure loss of pipeline, and system is caused serious harm.

Therefore, above-mentioned patent arranges filter cylindraceous at the inflow segment of pipeline shell, and the water of the inflow entrance of flowing through is filtered.In addition, in the bypass that is formed at inflow segment and flow out between the section pressure release valve is set, can open automatically because of outstanding pressure at pressure release valve, when discharging excess pressure from bypass, discharging is collected at the solid impurities such as iron rust on the filter in the lump, exempts the inconvenience of often cleaning or change filter.

Yet, because the inflow side of this inflow entrance is consistent with the outflow side size, therefore increase resistance or the pressure loss of pipeline easily.

On the other hand, this filter is that plastic cement rounding tubular skeleton and the metal screen by indivedual moulding combines, so manufacture cost is higher relatively; Simultaneously, this cylinder-shaped filter needs equivalent length, and the filtering effect of the expection of could volatilizing is relative, needs longer pipe road housing, causes cost of material and then to increase.

Filtering ring 12 adopts rustless wire netting to strike out ring-type (packing ring), and be shelved on the shelf 45 that extends radially outwardly from the internal groove side wall upper end edge of annular recess 29, and be centered around stripper loop 27 around, and remain between the surface of contact of pipeline shell 21 and dynamo-electric housing 22, the water that flows to annular recess 29 is filtered, with the solid impurities such as iron rust in the filtering water, guarantee that the water of the system that enters cleans, avoid it is worked the mischief.

Water turbine 13 comprises a volute 51, volute 51 is positioned in the below of the first shell chamber 42, a turbine chamber 52 is defined in the inside of this volute 51, and comprise that a pair of water inlet 53, of radially being located at shell wall and linking up turbine chamber 52 links up the axial spilled water hole 54 of turbine chamber 52 and valve chamber 20, reach one in order to define the hollow out support 55 of spilled water hole 54, the center of this support 55 has a post hole 56.In addition, water turbine 13 also comprises an impeller 57 that is arranged on turbine chamber 52, and this impeller 57 rotates around a wheel shaft 58.The two ends of above-mentioned wheel shaft 58 are separately fixed on the support 55 of the radial section of shielding can 41 and volute 51.

Generator 14 comprises a rotor 61 and a stator 62.Rotor 61 is made of some annular permanent 63 that are arranged in, and is positioned in the top of the first shell chamber 42, so as to producing desired magnetic field, and combines with impeller 57 and to rotate around wheel shaft 58.Stator 62 is arranged in the second shell chamber 43, and it has some field windings 64, and facing to rotor 61, the magnetic field that permanent magnet 63 is produced can conduct on the field winding 64 across the axial direction part of shielding can 41.

Electronic circuit 15 electrically connects the output terminal of stators 62, and with stator 62 together be synthesized resin-sealed in the second shell chamber 43, after the in addition rectification of Ac that stator 62 is produced, filtering and voltage stabilizing, by lead 65 outputs of a Belt connector.

Pressure release valve 16 is arranged in the valve chamber 20 of pipeline shell 21, is made up of a pedestal 71, a valve body 72 and a spring 73, and this pedestal 71 has post hole 56 slips that 74 of newels are held in volute 51.Valve body 72 is installed on the pedestal 71.Spring 73 for the pressure spring that compressive force is had an effect be centered around newel 74 around, prop up respectively on the support 55 that is held in volute 51 and the pedestal 71 at its two ends.Under the state of dynamo-electric housing 22 lockings, spring 73 can be compressed in pipeline shell 21, the sealing valve port 30 to borrow its elastic force to make valve body 72 usual adherences in valve seat 31.

Then being applied in gas heater with the disclosed miniature power hydroelectric installation 10 of the utility model is example, and its working principle is described.See also Fig. 3, when the hot water tap is opened, water flows to annular recess 29 from the inflow entrance 24 of pipeline shell 21 via intake tunnel 34, and after filtering, the filtering ring 12 on the annular recess 29 flows into the first shell chamber 42, water inlet 53 from volute 51 flows to promotion impeller 57 in the turbine chamber 52 again, enter outflow opening 25 via spilled water hole 54 and drainage channel 35 then, make impeller 57 can continue to accept the energy of current and rotate, and change together in the magnetic field that drive rotor 61 allows permanent magnet 63 produce, make the field winding 64 of stator 62 cut off the magnetic line of force that moves, thereby at field winding 64 inductions one Ac, and through electronic circuit 15 rectifications, after filtering and the voltage stabilizing, export a steady and enough direct current from lead 65, the electronic ignition device work of supplying with gas heater is required.

As shown in Figure 4, when hydraulic pressure surpasses the pressure that pressure release valve 16 is preset, the pressure that makes valve body 72 belows is during greater than the elastic force of spring 73, and valve body 72 will be opened automatically, discharges excess pressure, make the water of part flow to outflow opening 25 via bypass 26, allow rotor 61 accept stable flow energy and rotate, produce stable voltage, wash out the impurity that is collected on the filtering ring 12 simultaneously automatically, cause that with antifouling filtration is bad, increase resistance or the pressure loss of pipeline.In case when pressure dropped to preset pressure, valve body 72 was closed once again.

Need know that the utility model is not used in the restriction of gas heater, also be fit to other electronic equipment relevant with water power supply that the water heater of lifting is intended to illustration and explanation, and be not intended to limit any specific equipment that is used in.

Certainly, above-described embodiment can not break away under the scope of the present utility model in addition some variations, thus above explanation comprises and accompanying drawing shown in whole items should be considered as exemplary, but not in order to limit claim scope of the present utility model.
