Description
Technical field
The present invention relates to technical field of hydroelectric generation, especially a kind of river electricity generation system.
Background technique
River refers to the route that river water flows through, hydroelectric generation be located at using river etc. eminence flow to the water of potential energy it is low
Potential energy is converted into the kinetic energy of the hydraulic turbine by place, then borrowing the hydraulic turbine is that motive power pushing generator produces electricl energy.Due to water flow according to
Certain Hydrology Period constantly recycles, and has reproducibility as the energy, hydroelectric generation just with energy entrained by water flow,
It no longer needs to consume other power resources, and the used water flow in upper level power station can still utilize for next stage power station, power generation
Cost is relatively low, can provide the energy of inexpensive clean.But existing river hydroelectric installation needs constructing river dam
Concentrated flow drop, on the one hand invests huge, and the construction period is long, high construction cost, on the other hand when encountering dry season, in river
Water flow can not form the height of water, and when it is idle to often result in dam, or needing to remove dam, dam is often irremovable, makes
At a large amount of wasting of resources, while when encountering the flood season, dam may flood the culture such as good farmland, forest and historic site and set
The problems such as applying, the people caused to move.If can generate electricity using the flow velocity of streamflow, the clean and environmental protection energy can provide.Therefore how
A kind of river hydraulic floating power generator is designed, construction barrage dam is not had to, construction cost is low, conveniently moving, becomes existing
There is a research topic in technical field.
Summary of the invention
The purpose of the present invention is to provide a kind of river electricity generation systems, and especially one kind is with kickboard, permanent magnet direct-drive generator
The river electricity generation system of composition.
To achieve the goals above, this invention takes such technical measures, a kind of river electricity generation systems, including float
Plate, floating ball, guide support, drainage hood, propeller, permanent magnet generator, floating ball are connect by spring with guide support head, water conservancy diversion
Bracket tail portion is fixed with kickboard, is drainage hood below kickboard middle and back, has permanent magnet generator in drainage hood, permanent magnet generator passes through
Bracket is fixed in drainage hood, is had propeller at drainage hood aft exit and is connect with the shaft of permanent magnet generator.Drainage stent
Equipped with water conservancy diversion brush.There is waterproof layer outside magneto.Magneto is connected by water-proof cable with voltage-stablizer on ship or on the bank,
Voltage-stablizer is connected with electrical equipment.
Permanent magnet generator can also be placed in middle position above kickboard, and permanent magnet generator shaft passes through bevel reduction gear set and draws
The propeller connection of stream cover tail portion.There is no motor resistance in drainage hood, water flow is more steady to the impact of propeller, is conducive to mention
High generation efficiency.
The effect of water conservancy diversion brush is to expel river floater, prevents floating on water sundries from flowing into drainage hood, by spiral shell
Paddle winding is revolved, generating efficiency is influenced.
Kickboard, floating ball, guide support, drainage hood use light material, such as timber, plastics.Using hollow inside kickboard
Structure.Permanent magnet generator drives mode using straight, saves speed change gear, simplifies driving structure.Propeller blade is 2-6 piece.
3 kinds of fixed form of the river electricity generation system in river: one is fixed by hawser；Another kind is to pass through anchoring
In river；The third is that fixation hole is opened on guide support, passes through fixation hole with fixed link and is inserted into riverbed.River electricity generation system
Fixed form can be using the combination of one kind or any 2 kinds of modes of 3 kinds of modes or the combination of 3 kinds of modes.Hawser or anchor
Chain is connect with floating ball or kickboard.Floating ball is connect with guide support by spring, and influence of the water flow to floating ball generates it in water
It swings, so that drifting about with water flow and lower smallclothes drift shunting is obstructed by guide support, big part drift is put by floating ball
Opening not can enter drainage hood and can not impact drainage hood, ensure that the water flow into drainage hood does not have sundries.
Drainage hood import is big, exports small.Drainage hood is rectangular or round.Drainage hood import is big, and outlet is small, is conducive to improve
River flow velocity in drainage hood improves river water to the impact force of propeller, to improve generated energy.
River electricity generation system working principle: permanent magnet generator is stablized by floating ball and drainage stent in river by kickboard
Under the traction of anchor or hawser, river water is introduced to the entrance of drainage hood, river water flows into impact drainage hood from drainage hood entrance
The propeller in exit, propeller rotate under the drive of water flow, and then drive rotor of permanent-magnetic power generator rotation, realize power generation.
The present invention take after above-mentioned measure the utility model has the advantages that the configuration of the present invention is simple, is generated electricity using river flow velocity, not by river
Flowing water position influence does not need to build barrage dam, does not influence ecological environment.The present invention can be in upstream or downstream by end to end
Form or form arranged side by side are arranged, and can more improve generating efficiency in this way, make full use of water data.
For the present invention will be described in detail, the present invention is described in further detail below with reference to embodiment.
