Description

The two floating vessel type engine installations of low head

The utility model relates to a kind of engine installation that utilizes head of water potential energy for power, refers to especially a kind ofly utilize water valve to cause fluctuation in stage in tank and produce power drives the device of the power of generator for electricity generation.

The very abundant general mode of building a dam that in rivers, all adopts of the waterpower resourses of present China, utilize high water level drop potential energy to drive turbo-machine and generator for electricity generation, but in the brook in vast mountain area, build the dam and need bigger fund, and sometimes in the mountain stream streams, the comparison difficulty because geographical relationship is built a dam, and because Various Seasonal, waterpower resourses change greatly, be difficult for making full use of, particularly some low head regions want to utilize waterpower resourses difficulty especially.

The purpose of this utility model is to be that the low head that makes full use of mountain area streamlet or the little water source of mountain stream drives engine generating or required as other operation power as power.

The purpose of this utility model is achieved in that

The two floating vessel type engine installations of a kind of low head comprise that two have intake gate, go out the movable tank and the pontoon that is placed in the tank of water valve and middle water valve, there is trepanning at the pontoon middle part, by this trepanning one ring chain is arranged, two reverse ratchet sleeves are passed through on top sheave in this chain upper end, the chain lower end is enclosed within on the lower sheave, a bit is fixed on the pontoon in the middle of the chain; Described ratchet is fixed on the transmission shaft, and this transmission shaft is connected with electrical generator by free-wheel clutch, flywheel, speed increaser.

The utility model has the advantages that: 1, need not change the expense great amount of investment and build the dam drop of flooding, and can be owing to reservoir occupies a large amount of rural holding.2, itself is simple in structure, is convenient to implement and can make full use of conventional device and other parts.3, decide according to local water resource, changeable, make full use of mountain area or remote rural mountain stream stream, little water source and low head.And can be made into movable tank and small-sized pontoon and after factory carries out serial batch manufacturing, move on to the building site and install.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the two floating vessel type engine installation overall structure scheme drawings of the utility model low head.

Fig. 2 is for two ratchets and lead white silk wheel scheme of installation.

Fig. 3 is for two ratchets and lead experienced wheel work scheme drawing.

Fig. 4 is free-wheel clutch (overriding clutch) constructional drawing.

The utility model is described further below in conjunction with drawings and Examples:

See also Fig. 1, in giving tank A that making sheet is assembled into and tank B, respectively place a pontoon 1a and 1b is equipped with chain cable fairlead 4 and ratchet 2, ratchet 3 on tank A, B top.Please consult Fig. 2 simultaneously, this ratchet 2 and ratchet 3 are fixed on the transmission shaft 5, but the ratchet effect direction (is that one of them just changes on the contrary, another counter-rotating is skidded), on chain cable fairlead 4 and ratchet 2,3, intersect and be with chain 11, these chain 11 upper ends are enclosed within on the pulley 4, and the bottom is enclosed within on the pulley 13, the centre pass pontoon 1a (or 1b) trepanning 21 and the point 12 with hull dead admittedly.Transmission shaft 5 two supports and are connected with flywheel 7 by free-wheel clutch 6 on bearing hole 19, and that stretches out in flywheel 7 rear ends spool passes through speed increaser 8 and be connected with electrical generator 10 through flange 9.4 on pulley slides on the axle 20, and axle 20 is fixed on the side wall of tank A, B.Intake gate 14,16 is housed on tank A and tank B and go out 15,17 and between tank A, B, be equipped with in the middle of water valve 18.

Say working process and principle below again: when the water valve 14 of tank A opens water valve 15 and cuts out, (water valve 16 closes at this moment, 17 open) river fills tank A gradually by water valve 14, this moment, pontoon 1a was subjected to buoyancy F1 rising, because chain 11 is dead admittedly at point 12 and hull, so being driven, the inboard of chain 11 makes progress, by pulley 13, chain 11 outsides become and move down and drive ratchet 2 by clockwise direction rotation, and this moment ratchet 3 (see figure 2) of skidding.Transmission shaft 5 connects by free-wheel clutch 6 and flywheel 7, makes flywheel 7 drive electrical generator 10 generatings with uniform rotation and by speed increaser 8.

The water that closes valve water valve 14 and open among middle water valve 18 (this moment, water valve 17 cut out) the tank A when pontoon 1a arrives extreme higher position (top dead point) flows into tank B, A median water level decline this moment B median water level rising pontoon 1a descends by certain gravity F2 and does work, pontoon 1b rises equal up to two groove water levels by buoyancy, water valve 18 in the middle of closing this moment, open water valve 15 and 16, (water valve 17,14 is in closed condition) pontoon 1a continues to descend, and pontoon 1b continues to rise.

Chain 11 counter motions when pontoon 1a descends, driving ratchet 3 is just changeing, and ratchet 2 idle running this moment.(see figure 3)

Pontoon 1b is identical with pontoon 1a, no longer detailed here in the rotation situation that rises with decline process drive ratchet, and two pontoons all drive ratchet 3,2 and the rotation of transmission shaft 5 clockwise directions at lifting process in a word.

Can sum up above process as follows:

1, water valve 14 leaves, 17 opens, and 15,16,18 close pontoon 1a rises and descend up to bottom dead point up to top dead point 1b.

2, water valve 14 closes, and 17 close, and 18 open the pontoon 1a 1b that begins to descend begins to rise, flat up to two groove water levels.

3, water valve 18 closes, and 17 close, and 14 close, and 16,15 open, and pontoon 1a is lowered to bottom dead point under continuing, and 1b continues to rise up to top dead point.

4, water valve 16 closes, and 15 close, and 18 open pontoon 1b begins to descend, and 1a begins to rise.

So: by 1 → 2 → 3 → 4 → 1 ... circulate.

Electrical generator in the utility model power system is according to actual conditions needs also air compressor, other Work machine such as water pump.

Design according to actual conditions tank and pontoon is changeable.

Reality of the present utility model revolves that to execute example two be that tank is made movably tank, pontoon is made buoyancy tank or floating drum, other device and structure and embodiment one are identical, and just each size is all smaller, and above-mentioned movably tank can be made with the steel plate welding, also can give making sheet with reinforced concrete and make.The low head twin float engine installation of this miniaturization is suitable in factory's producing in serial form and moves to the place with small hydro resource, buying the water phase removable, can be in many water phase how with several.

Free-wheel clutch 6 of the present utility model can adopt a kind of overriding clutch, (see figure 4), its concrete size, standard, structure can be selected for use according to national standard, and speed increaser 8 can adopt speed-changing gear box, manipulation about water valve is by travel switch, relay, and motor and actuating unit carry out, because of all belonging to general prior art, no longer described in detail here.

The utility model can also utilize morning and evening tides, by the sea or the bank on island utilize hulk body and tank that this power system is installed to generate electricity.
