Description

Transmission chain type hydraulic turbine

Technical field

The utility model relates to a kind of water conservancy machinery that utilizes the water energy, specifically a kind of transmission chain type hydraulic turbine.

Background technique

At present in the low water head generating, according to different water levels, flow, flow velocity, modulability is used the property built up current, and the hydraulic head pressure that the property built up current are set up acts on the whole blade in the device cavity volume, obtain more flow energy utilization ratio, also can be used for the high potential energy current and use, but its poor effect so that up till now the river stream of low water head, river, ocean current under the situation of not building the dam, on Waterpower Resources Development, there are not effective measures or water wheels device.Application number is 98101697 Chinese patent application, the technological scheme of a kind of " low head water turbine " is disclosed, it adopts the form in intercepting property use acting cross section, it is equipped with penstock, when current enter water intake to penstock from horizontal plane, form shelves water plate and moved by matter, drive the sprocket wheel running, and drive the acting of rotating shaft rotating generator.The stressed shelves of this scheme water plate is few, poor effect on the current functional utilization.

Summary of the invention

The purpose of this utility model provides and a kind ofly can make full use of flow energy, adjustable transmission chain type hydraulic turbine.

The technical scheme in the invention for solving the technical problem is: it comprises the band plate of connecting on chain wheel set, chain, the chain, it is characterized in that also comprising the baffle plate of U-shaped kerve, both sides, they and band plate decomposition pressure formula cone cavity volume, sprocket shaft is installed on the lifting landing leg, and coaxial package has adjustable flap bucket shape waterpower plate on the band plate.

Have on the arc of the adjustable flap bucket shape waterpower plate both sides hand hay cutter plate to penetrate series connection adjusting axle curve bath, there is positioning hole on the curve bath both sides, and the aperture α angle of adjustable flap bucket shape waterpower plate and chain direction along the line is 0 °≤α＜180 °.

The band plate of connecting on the chain of water turbine, through the lift adjustment of lifting landing leg, the adjusting angle of its water (flow) direction is β, 0 °≤β＜90 °.

The adjusting angle α of water turbine, β angle, fit angle between the two is: α=90 °, β=45 °.

The utility model has following beneficial effect:

Bucket and pressure type cone cavity volume that band plate of the present utility model and waterpower plate form are adjustable, utilize at the current of low water head, according to different water levels, flow, flow velocity, modulability is used the property built up current, so that low water head potential energy is improved, so that the hydraulic head pressure that the property built up current are set up all acts on the whole blade bucket in the cavity volume, make it all to be in meritorious working state, having improved water can utilization ratio.The utility model also can be used for the flowing water environment that the dam is arranged of high head potential energy, and can answer different generate outputs, and different spontaneous current water environments are improved the Technological Economy of flowing water generating.
