Description

A kind of flowing water power generation device

Technical field

The present invention relates to a kind of flowing water power generation device.

Background technique

The existing device that utilizes water for producing electric power build a dam formula and impeller type.

The formula of building a dam to form high drop, is applicable to large-scale power station as the term suggests need build a dam.

The single impeller of impeller type can be by being contained on the buoyancy tank or directly being fixed on the riverbed, and the impeller bottom is under water to be promoted rotation by current, and impeller shaft drives generator for electricity generation.Its deficiency is exactly that impeller has only several blades to soak in water to be promoted by current, especially when the riverbed is more shallow, perhaps have only one or two leaf blade to soak in water, the impulse force that can not make full use of riverbed length direction current generates electricity, and makes that generated output is difficult to improve.

Summary of the invention

Technical problem solved by the invention just provides a kind of simple in structure, flowing water power generation device that can float over the impulse force generating that makes full use of river length direction current on the river water surface.

Realize above-mentioned purpose, the technical solution adopted in the present invention is:

A kind of flowing water power generation device is characterized in that comprising:

One floating platform or four are fixed in the river bed fastening foot, the plane type framework of floating platform for making as member with buoyancy tank can float on the surface, all the time as the mountion plate of other mechanisms, the platform front end is provided with fixedly anchor chain, is used for fixing whole flowing water power generation device and is unlikely to be washed away by current;

Conveyor type is subjected to force mechanisms, comprise: endless belt or chain conveyor before and after being looped around on belt pulley or the sprocket wheel, before and after belt pulley or sprocket shaft two ends respectively by the bearing support adjusting height be supported on four fastening foot or two vertical buoyancy tanks of floating platform on, line belt is provided with a plurality of floating drums;

Generator set directly or by gearbox is connected on front or rear moving belt pulley or the sprocket shaft.

Electricity generating principle: when being put into this device in the river, current with certain flow rate promote floating drum under water, floating drum drives line belt and moves in circles, belt pulley or sprocket wheel rotation before and after line belt drives, and the front or rear moving belt pulley or the sprocket shaft that are connected with generator set drive generator for electricity generation.

On the basis of the above, this device can also be perfect further:

Described floating drum two ends are provided with spindle nose, and the spindle nose end is equipped with roller, are arranged with vertical circulation rolling wheel guide rails on adjusting height ground on four fastening foot or two vertical buoyancy tanks at floating platform, and the circulation rolling wheel guide rails correspondence on both sides the roller at floating drum two ends.Can alleviate floating drum gravity or float buoyancy pressure like this, make line belt remain level line belt.

Have the hole on the described buoyancy tank and be provided with lid, be used for pouring into or discharge water, soak the height of keeping afloat, regulate the floating drum immersion degree of depth under water thus to best stress to regulate floating platform.

The cross section of described guide rail is a rectangle frame, and inboard edge has the breach that cooperates roller shaft, and inside bottom surface is a raceway, and roller puts in the rectangle frame, so can limit simultaneously roller about wander off.

The described guide rail outside by several upright supports on two vertical buoyancy tanks of floating platform.

The means of fixation of described line belt and floating drum is: floating drum interior bottom portion neutral position is fastening by laterally single bolt and line belt, so just makes the line belt that is fixed with floating drum still can be attached to when licking sprocket wheel and is unlikely to take off chain on the sprocket wheel.

Beneficial effect: this device need not to construct dam, not needing water surface drop also can generate electricity, device is put on the water surface with anchor chain is fixing gets final product, can float over the impulse force generating that makes full use of river length direction current on the river water surface, the generated output size is by floating drum size and quantity decision, line belt can be accomplished very long, numerous floating drums is set to improve generated output.
