Description

A kind of invention utilizing tall building sewer to drive electrical power generators

Technical field

This invention is the kinetic energy utilizing tall building sewer, and driving the cutting movement acting in magnetic field of the coil of generator to produce electric energy, is exactly microhydro in fact.

Background technique

Modern society's tall building gets more and more, and utilizes the wheel rotation that tall building sewer drives generator shaft fixing from the kinetic energy impact that high-storey is arranged, staor windingcoil cutting magnetic lineproduce electric energy.It is similar with wind-driven generator principle, wind-power electricity generationprinciple, be utilize wind-force drive air vane rotate, then through booster engine will rotate speed promote, impel generatorgenerating.Wind-power electricity generation requires too high to geographical position and physical environment.What my this invention adopted is that sewer hydroelectric power obtains conveniently.The domestic sewage of current high level is all pour off in vain, and the kinetic transformation sewer is become electric energy by this invention.

Embodiment

Arrange one " cumulative wet pit " at the transfer floor of tall building or annex top, cumulative reservoir capacity is not less than 2 cubic metres can not be greater than the capacity that building structure can carry weight after cumulative wet pit full water, refer to accompanying drawing 3,4, wet pit position is more high better, head is higher, and kinetic energy is larger.The used sewage of unit users each above wet pit is converged to this pond, after tank water is full, buoy floating in pond has been communicated with drain valve and has opened control loop, draining opened by drain valve, because drop, sewage down discharges from " converging cumulative sewage pipe " with pressure fast through filter screen, this water pipe reduces the kinetic energy strengthening water again to last water outlet, aim at generator impeller closely vertical impact, drives impeller quick rotation, and change through generator and change into electric energy.Refer to accompanying drawing 1,2.When cumulative wet pit sewage drains, the buoy in pond sinks to because sewage declines at the bottom of pond and is communicated with valve closing control loop, drain shut valve, waits for second time retaining." cumulative wet pit " is provided with spilling water water outlet, time malfunctioning in order to drain valve, the sewage overflowed is entered " converging cumulative sewage pipe " discharge and generates electricity.If there is sewage to enter wet pit in drainage procedure simultaneously, that cumulative wet pit water discharge time lengthens, and more favourable lasting draining drives generator to rotate generating in rated speed.Rated speed presses formula according to generator magnetic pole logarithm: revolution=50x60/p (magnetic pole logarithm) sets.The building many and lasting for the sewer water yield can adopt " converging cumulative sewage pipe ", and converge to the pipeline reduced a down draining after through filter screen at annex holder-on sewage, point is more high better, and head is higher.Waste pipe diameter is mated with this building water amount of blowdown, can fill water pipe and form larger pressure, and in the end water outlet reduces again, obtains the generating of larger pressure rear driving generator rotation.What, head few in the sewer water yield was low build a building first can drive waterwheel to rotate again with the large gear turn the small gear raising speed drive electrical generators generating with sewage.The selection of generator power size can reference formula: power (KW)=head (H) X flow (cubic meter/S) X unit efficiency X gravity accleration (g).The last water outlet of drain pipe is aimed at generator impeller vertical impact and is driven electrical power generators, and we cover water outlet and impeller and prevent sewage from splashing with " receipts catchment covers ", sewage concentrates outflow to unify blow-off line discharged to municipal administration from " receipts catchment covers " below.The transmission shaft of generator, entering greatly in storehouse, magnetic field with three grades of step types changes, prevents the water breakthrough on impeller from entering.Building sewer does not continue, the water yield is also unstable, therefore its 13 ~ 25V change exported ac, must, again to 12V storage battery charge storage after rectifier, make sewer hydro powered miniature generatorthe electric energy produced becomes chemical energy.Then with there being protective circuit inverter, in storage battery chemical energybe transformed into alternating current 220V civil power, flow to the stable use of all kinds of consumer, refer to the system schematic 5 of accompanying drawing.
