Description
Technical field
The invention belongs to technical field of new energies, more particularly to a kind of self-shield water pumping of the wind-force system with speedup blade
System.
Background technology
New forms of energy show increasingly consequence and effect in the development convexity of current economic society.Wind energy is as one kind
Cleanliness without any pollution and cheap regenerative resource and receive extensive utilization.The mode of Wind Power Utilization at present mainly has two
Kind, a kind of is to convert wind energy into mechanical energy by the device of wind-power electricity generation, then by electromotor, mechanical energy is converted into electric energy
Be connected to the grid and be used, this Wind Power Utilization mode is studied relatively to go deep into, defined maturation wind-powered electricity generation theoretical and
Industry Model, however this wind-power electricity generation need complex control system in addition it is also necessary to electromotor, converter etc. costly
Electrical equipment；Another kind is using machinery, wind energy to be converted into mechanical energy to be directly used, and water pumping of the wind-force fills
Put and belong to this category.Water pumping of the wind-force uniquely relies on natural wind-resources and drives water pump to complete water lift operation, with wind-power electricity generation
Device compares that its frame for movement is simple, with low cost, operation and maintenance convenient, but water pumping of the wind-force also has many and is difficult to solve
Problem, as more in the number of blade, blade wind energy utilization is low, power is less, blower fan is with water pump the problems such as coupling, and these are all
Water pumping of the wind-force is made to await furtheing investigate further.
Chinese patent application 201110316710.1 discloses a kind of " wind water lifting irrigation system ", and it is formed using bent axle
Toggle carrys out the wind water lifting irrigation system of water lift；Disclosed " the water pumping of the wind-force of Chinese patent application 200320104849
Device " is the wind-powered water lift collected folk songs using multiple wind wheel large area, but wind wheel still adopts arc multi-vane chip architecture, and does not have
There is the dead-man's device under strong wind state；Chinese patent application 201310358909.X discloses a kind of wind-driven water pump,
The wind-driven water pump of deep layer water lift and shallow-layer water lift can be carried out, but arc multi-vane chip architecture is not improved；Chinese patent
Application 200810119891.7 discloses a kind of vertical shaft giant energy and energy-collecting wind water lift unit, that is, by multiple vertical shaft giant energy wind energy conversion systems
The vertical-shaft wind water pumping system of the muck in that series connection is formed, but because the power coefficient of vertical-shaft fan is relatively low, moment of torsion
Little and multiple vertical-shaft fan series connection, not only manufacturing cost increase, and also the efficiency of Wind Power Utilization is still not high enough；Chinese patent
Application 201210161249.1 discloses a kind of pneumatic equipment bladess with embedded mozzle although reducing to a certain extent
Noise and tip vortex, but because its gas outlet is opened in leaf top, blade radial can be caused with one when air-flow sprays at a high speed
Very big counteracting force, increased the stress load of wheel hub and pylon, has both had influence on the wind energy utilization of unit, has increased again
Its manufacturing cost.
The wind-powered water lift having formed industrial scale at present is using multiple-blade, the slow-speed of revolution, low wind energy profit mostly
With the system of rate, making rotor solidity larger the number of blade, the air-flow flowing through wind wheel is less, thus have impact on its output more；
Meanwhile, the design of blade adopts traditional plate or arc template mostly, and wind energy utilization efficiency is relatively low, easily causes wind energy resources
Waste.In sum, the efficiency how improving water pumping of the wind-force system is that emphasis urgently to be resolved hurrily in technical field of new energies is difficult
One of topic.
Content of the invention
