The utility model is characterized in that a step-shaped hole cavity is arranged in the electric generator housing. The electric generator housing is provided with a fluid inlet opening. A fluid outlet is arranged at a corresponding side. The stator part of the electric generator is provided with a rotor shaft of the electric generator. A bearing, an impeller and a magnet ring are arranged on the rotor shaft of the electric generator. The stator part of the electric generator is provided with an end housing of the electric generator. Stator coils are arranged in the end housing of the electric generator.
Description
What the utility model tubular type micrometeor generator related to is a kind of for solving the automatic data logging and the data passes of city dweller sub-district water, gas meter, relevant electronic circuit is provided the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of power supply.
In order to guarantee water-gas-electricity-meters automatic data logging and data passes electronic circuit operate as normal, all adopted the method that battery is installed in the past.The disadvantage of this method is to regularly replace battery.Because water, gas meter (particularly water meter) generally are installed in short, narrow place, environment is relatively moister, not only is affected the useful life of battery, and changes very difficulty.If just increased user's financial burden with long-life, high performance battery, the same problem of changing difficulty that exists.
The purpose of this utility model is to provide power supply to exist weak point that a kind of tubular type micrometeor generator is provided at present water, gas meter automatic data logging and data passes electronic circuit, as long as in Yuan Shui, gas meter pipeline, install nearby, can produce is enough to pass to the automatic data logging of corresponding water, gas meter and the power supply of data passes electronic circuit, and can be for a long time, work reliably.
Tubular type flow generator takes following scheme to realize: tubular type micrometeor electric generator structure partly is made of electric machine casing, generator amature part, generator unit stator.Be provided with the step vestibule in the generator housing, be respectively bearing mounting hole, impeller installation cavity, bearing pedestal installing hole.Generator housing is provided with fluid intake, and corresponding side is provided with the fluid flow export, and the fluid inflow entrance has taper undergauge hole, and the fluid inflow entrance is with the fluid flow export, be connected with the impeller installation cavity.Generator unit stator partly has generator ' s cover, and stator coil is housed in the electric motor end cap.Generator amature partly has generator rotor shaft, bearing, impeller, magnet ring are housed on the generator rotor shaft, the bearing of generator amature part, impeller assembling device are in generator housing step vestibule, device has bearing pedestal in the bearing pedestal installing hole of generator housing, and device has sealing ring between bearing pedestal and the bearing saddle bore.The magnet ring device matches with the generator unit stator coil sections at generator rotor shaft one end.Generator ' s cover is fixed on the generator housing.
Operation principle: tubular type micrometeor generator is installed in former water, the gas meter fluid circuit nearby, fluid flows into through the generator housing fluid intake, through the undergauge hole to improve flow velocity, impeller on the impulsion generator rotor shaft makes the generator amature rotation, drives the magnet ring cutting magnetic line, on stator coil, produce electromotive force, as long as certain flow is arranged, generator just can be worked, and the automatic data logging and the relevant electronic circuit of data passes of feedwater, gas meter provide power supply.Fluid flows out through generator fluid flow export.
Tubular type micrometeor generator designs is reasonable, simple in structure, easy for installation, as long as install nearby in Yuan Shui, air pipe.The external connecting line of this generator has only two, is convenient to isolate, seal.Adopt this generator, exempted the worry work of responsible periodic replacement battery, the once mounting success is used forever.This generator can be used in the pipe-line system of micrometeor (flow is better greatly), produces the power supply be enough to supply with corresponding electronic circuit, and can be long-term, safety, work reliably.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a tubular type micrometeor electric generator structure schematic diagram.
With reference to accompanying drawing, tubular type micrometeor electric generator structure partly is made of generator housing 2, generator amature part, generator unit stator.Be provided with the step vestibule in the generator housing 2, be respectively bearing mounting hole 14, impeller installation cavity 16, bearing pedestal installing hole 17, generator housing 2 is provided with fluid inflow entrance 1, the fluid inflow entrance has taper undergauge hole and has pipeline to connect internal thread, be provided with fluid flow export 12 in generator housing fluid inflow entrance 1 corresponding side, the fluid flow export has pipeline to connect internal thread.The fluid inflow entrance is with the fluid flow export, be connected with impeller installation cavity 15.Motor stator partly has generator ' s cover 5, and stator coil 8 is housed in the generator ' s cover, and stator coil winding is on skeleton 10, and stator coil has power supply output line 9.Generator amature partly has generator rotor shaft 6, device has bearing 13,15, impeller 11, magnet ring 7 on the generator rotor shaft, the bearing of generator amature part, impeller unit are in generator housing step vestibule, its middle (center) bearing 13 is installed in the bearing mounting hole, impeller is installed in the impeller installation cavity, bearing 15 is installed in the bearing pedestal 4, and bearing pedestal 4 devices are in generator housing bearing pedestal installing hole 17, and bearing pedestal 4 has sealing ring 3 with the device of bearing saddle bore 17.Magnet ring 7 devices match with generator unit stator coil sections 8 at generator rotor shaft one end, and generator ' s cover 5 is fixed on the generator housing.
