Device is connected, and 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 guide support 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 utility model takes after above-mentioned measure the utility model has the advantages that the utility model structure is simple, is sent out using river flow velocity
Electricity is not influenced by river level, is not needed to build barrage dam, is not influenced ecological environment.The utility model can upstream or under
Trip is arranged by end to end form or form arranged side by side, can more be improved generating efficiency in this way, be made full use of water data.
For the utility model is described in detail, the utility model is described in further detail below with reference to embodiment.
