Description

Flowing water power generation device

Technical field: relate to a kind of hydroelectric flowing water power generation device.

Technical background: the patent application of flowing water generating is in recent years a lot, wherein the power generation system of pontoon, water turbine, speed changer, generator composition is in the majority, but has a common shortcoming: current utilization ratio is little.The energy of flowing water itself is just very little, then adds under ship and both sides current lose too much, and the efficiency that water can be converted to electric energy is just lower.If flowing water is blocked to guiding all to be entered water turbine and can improve waterpower utilization rate.

The rotational speed of water turbine of flowing water generating is low, blade area causes greatly the feature that runner volume is large, the big and heavy amount of axle is large, and alloy watt can move bad.Thrust elastic metal plastic bearing has been widely used in large-scale vertical unit, horizontal radial elastic metal plastic bearing is applied to again among the main bearing of large-scale bulb through-flow hydraulic generator unit, has obtained good operational effect (seeing application 201110165843.3).This technology should be included flowing water generating in.

The stable poor torsional deformation of pontoon is inevitable.The bearing of spherical support has the ability of clearing up torsional deformation between axle and basis.This technology is applied to hydroelectric generator group and can obtains good operational effect.

Vertical Francis generator and vertical tubular generator structure inspire to us, and the new architecture that both are combined can be applied in flowing water generating.

According to the imagination of these ideas propositions the present invention above.

Summary of the invention: relate to a kind of hydroelectric flowing water power generation device, be made up of pipelined channel, pontoon, water turbine, speed changer, generator, it is characterized in that pipelined channel leading portion installation folded form manger board, back segment is the up and down space of hydraulic generator pontoon; Folded form manger board two end part have guide wheel to insert guide groove to move up and down, and river bed is close on lower flap portion limit, goes up folded plate margin most and connects hydroturbine water intake chamber mouth, bearing pin link between flap; The rotary wheel of water turbine bearing of hydraulic generator pontoon is elastic metal plastic bearing structure.Hydraulic generator pontoon is gutter channel axle horizontal type gear leaf hydraulic turbine structure, and runner shaft is seated on pontoon by spherical support.Generating pontoon is vertical shaft extension vertical turbine structure, and pontoon leading portion has intake chamber, and vertical circular flowing water well is in succession installed vertical shaft type runner in well, and runner vertical shaft stretches out water guide cone, upper spider, supports link gearbox and generator by thrust-bearing.

Beneficial effect: folded form manger board can open along with the lifting of pontoon gathering, is remaining whole flowing water is all imported to water turbine mouth, enters water turbine and has improved waterpower utilization rate.

Water turbine thrust and radial bearing are the safety and reliabilities that elastic metal plastic bearing structure and horizontal axis spherical support have school and improved unit operation.

Generating pontoon is vertical shaft extension vertical shaft water turbine structure, and a kind of novel hydroelectric generator structure is provided, and runner vertical shaft stretches out water guide cone, upper spider lid, makes thrust-bearing, gearbox and generator all more than the water surface, is convenient to install, maintenance.

Brief description of the drawings: Fig. 1 flowing water power generation device side-looking generalized section

Fig. 2 flowing water power generation device schematic top plan view

Fig. 3 hydraulic generator pontoon is vertical shaft extension vertical shaft water turbine structural drawing

Embodiment: accompanying drawings is as follows.Be horizontal at Fig. 1 and Fig. 2, pipelined channel 19 is steel concrete building structure, and 20 liang of walls of its leading portion are parallel, have guide groove 9, and folded form manger board 6 is installed, and back segment is the up and down space of hydraulic generator pontoon 1.Folded form manger board 6 end guide wheels 8 insert in guide groove 9, and river bed is close on the lower flap portion of manger board 6 limit, and drive unit 4 can make it move up and down, and goes up folded plate margin most and connects water turbine gutter channel 10,13 entrance parts.Bearing pin link between flap, seals with folding between centers water-filled capsule 7 between flap and leading portion 20 walls.Gutter channel 10,13 pontoons 18,11 are an entirety.After pontoon, there is gear wheel 17 to support.The gear blade 12 of gear leaf water wheels 3 is curve shapes.Runner shaft 2 bearings are elastic metal plastic bearing structures, are seated on pontoon 11,18 by spherical support 14.Runner shaft 2 connection speed variator structures 15 and flywheel 21.Generator 16 connects gear 15.The control of inflow has the gate mechanism 5 of gutter channel to carry out.

Fig. 3 is vertical shaft extension vertical turbine pontoon structure, pontoon 21 leading portions have intake chamber 29 water intakes, vertical circular flowing water well 28 in succession, vertical shaft type runner 34 is installed in well, runner vertical shaft 23 stretches out water guide cone 35, upper spider 27, be supported on thrust bearing shoe valve 32 by the runner plate of thrust collar 24, thrust collar 24 also links speed change gearwheel 25, and small gear connects generator 22.The plate 30 that folds is connected under intake chamber 29 water intakes by movable axis 31.Runner lower guide bearing 33 is arranged on the lower end of water guide cone 35, and top guide bearing 26 peace and quiet are in upper spider.Thrust bearing shoe valve 32, top guide bearing watts 26, down guide bearing bush 33 are all elastic metal plastic bearing structures.Supporting wheel 36 is fixed pontoon.

Power station of running water is to be combined by several above-mentioned electricity generating devices.Can be formed by the electricity generating device of same model with seat power station, be convenient to install, overhaul.Also can different model combination.The electricity generating device runner volume of gutter channel axle horizontal type gear leaf hydraulic turbine structure is large, and operation noise is also large.The volume of vertical shaft extension vertical water turbine structure is relatively little, and operation noise is also less.

Single seat power station of running water is there is no actual economic implications, only has with storage station or the networking of battery station and just can give play to economic benefit.Particularly whole river basin is no more than 1 meter according to the height of water and builds up and down a power station of running water, and performance basin constellation effect can demonstrate economic benefits.
