Technical field
The present invention is to be related to hydraulic power generation technology, is to be related to a kind of hydroelectric installation specifically.
Background technique
It is well known that water resource is valuable cleaning renewable resource, it can be used as the long-acting means that the energy restricts that solve.
Current hydroelectric principle is mainly to utilize kinetic energy possessed by the powerful water flow of water-head generation that the hydraulic turbine is pushed to drive hair
Motor group and generate electricity.It is essentially all now that hydroelectric generation is carried out using screw blade formula, such as: diameter being installed in water and is reached in the U.S.
70 meters of propeller power generation, is rotated using water jet propulsion propeller, drives electrical power generators.But the power generation of this propeller rotation
Method has the shortcomings that manufacturing cost is high, and especially the linear velocity at blade edge is high, resistance is big, and there are the low difficulties of water energy conversion ratio
Topic.By taking diameter is 70 meters, revolving speed is the propeller of 10r/m as an example: the edge linear velocity of blade reaches 36.6 meter per seconds, is equivalent to
121 kilometers/hour of water resistance.The presence of this water resistance can greatly consume the kinetic energy of water flow itself, and generated energy is caused to subtract
It is few.Why not generated electricity with impeller because when impeller rotates under waterpower promotion, the top blade of wheel shaft and lower leaflet
Direction of rotation be it is opposite, this phase reverse rotation will repeal by implication motive force, cause energy consumption is high, generating efficiency is low, power generation at
This height, without practical value.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, the object of the present invention is to provide a kind of hydroelectric installation, with it is low at
Sheet, low energy consumption, high efficiency realize hydroelectric generation, to promote the scale application of waterpower resourses.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of hydroelectric installation, including impeller and impeller shaft, the impeller include blade, it is characterised in that: the leaf
The installation of wheel need to make to constitute at the partial blade of impeller in air, and remaining blade is in water flow.
The present invention places the upper blade opposite with water (flow) direction in air, since the specific gravity of air only has the eight of water
1 percent, and air is relatively stationary, in this way, suffered air drag is remote when upper blade is reversely rotated
Generating power by water current efficiency is improved much smaller than resistance caused by water flow so as to which the loss of water energy is greatly lowered.
Preferably, make the blade locating aerial blade Yu being in water flow distribution in a center of symmetry.It is this
It is symmetrical that the blade in water can be made to be immersed in water flow as far as possible, it can be acted on by maximum water energy.
Preferably, the blade is arc shaped blade.When arc shaped blade is opposite with water (flow) direction, can get bigger
Water jet propulsion power.
As further preferred scheme, baffle is equipped at the both ends of arc shaped blade.At the both ends of arc shaped blade, baffle is set,

Preferably, the hydroelectric installation further includes U-shaped beam sink, and impeller is located in the U-shaped beam sink.
It is acted on by the line of beam sink, water flow can be prevented when pushing blade, will not be spread to other directions, so that water flow is dynamic
Power is only limitted to the direction of rotation of impeller, to further increase the utilization efficiency of water energy.
Preferably, the front end of the impeller be equipped with pod, the bore of the pod from large to small, into
It is heavy caliber at the mouth of a river, is small-bore at the front end of impeller.By the guide functions of pod, more water flows are introduced into
In hydroelectric generator, so that the working efficiency of hydroelectric generator can be improved.Such as: the water inlet of impeller is 5 meters × 20 meters, now logical
Cross the effect of pod, the size of the water inlet of pod is 15 meters × 20 meters, width and it is original, but height is original
Three times；The water outlet of pod is still 5 meters × 20 meters, identical as the water inlet of impeller, and is connected therewith.Pass through pod
15 meters × 20 meters of water energy is introduced into 5 meters × 20 meters by guide functions, and inflow increases three times, can to substantially increase
The water energy of power generation.
As further preferred scheme, switching door is equipped on the pod.Work is opened or closed by switching door
With can constantly adjust the size of inflow, flow is made to be in relatively steady state, to guarantee generated electricity quality.
As further preferred scheme, the rear end of the pod and the front end of U-shaped beam sink are connected as one.This company
Connecing can guarantee that the two is combined into one, and can increase the convenience of installation and reduce manufacturing cost.
Preferably, at least one output wheel is installed in the impeller shaft, the output wheel has clutch function
Energy.The size of water flow be it is continually changing, by installing one or more power transmission wheel in impeller shaft, work as water flow
When becoming smaller, partial power transmission wheel separation therein is set to guarantee power generation product to reduce generation load by clutch connection function
Matter；Equally, when water flow becomes larger, power transmission wheel therein is connected, increases generation load, so that water flow be made full use of to send out
Electricity, and guarantee the quality that generates electricity.
Preferably, water (flow) direction adjustment axis, the water (flow) direction tune are vertically equipped at the middle part of the impeller shaft
Nodal axisn can be vertical with water (flow) direction holding according to water (flow) direction variation automatic adjustment impeller shaft, to improve hydroelectric generation efficiency.
Preferably, guiding rudder is equipped on the impeller or in impeller shaft or in water (flow) direction adjustment axis.Once
Water (flow) direction changes, and guiding rudder can be under flow action, and adjusting direction blade is vertical with water (flow) direction holding, to improve waterpower
Generating efficiency.
Compared with prior art, the invention has the following beneficial effects:
By the present invention in that constituting at the partial blade of impeller in air, remaining blade is in water flow, to make to revolve
Turn the direction blade opposite with water (flow) direction be no longer influenced by water flow reversed resistance and only air drag, since air drag is remote
Much smaller than resistance caused by water flow, thus the loss of water energy can be greatly lowered in the present invention, improve generating power by water current efficiency, through counting
It calculates, generating efficiency generates electricity relative to existing propeller, at least can be improved one times or more；Especially, when end setting before the impeller
When pod, waterpower utilization rate can be increased to existing two times or more；Therefore, the present invention can low cost, low energy consumption, high efficiency
The hydroelectric generation for realizing high-quality has important value to the scale application for promoting water flow resource.
