Description
Technical field
The present invention relates to green energy resource power generating equipment technical field, particularly a kind of water turbine automatic open-close blade.
Background technique
Under energy consumption continues external environment influence soaring and that traditional energy is increasingly in short supply, seek and develop new energy and become trend of the times.Ocean energy is a kind of renewable energy sources of clean, environmental protection, and China is ocean big country, has the marine site of more than 300 ten thousand square kilometres, 18000 kilometers of shore lines, and marine energy resources enriches, and DEVELOPMENT PROSPECT is considerable.The main form that utilizes of current ocean energy generates electricity exactly.China also has drainage area in more than 1500, the river of 1000 square kilometres simultaneously, and the runoff formed because of river drop can be also inestimable, and be limited by the reason of each side such as technical equipment, the utilization rate of these energy is also very low.
The present inventor in application number be in the Chinese patent of 2014204172214, disclose a kind of multifunctional generating equipment utilizing seawater, river and wind-power electricity generation, can be mechanical energy by the Wind resource change on ocean current energy, tidal energy, runoff energy and the water surface, mechanical energy is converted to electric energy, achieve the three-dimension use of water energy, in suitable marine site, river, can also generate electricity by water turbine under water, above-water wind generator generates electricity, realizing the comprehensive utilization of the energy, is a kind of completely newly with desirable power generating equipment.But because low-speed water turbine leaf fan resistance when rotating against the current is large, waterpower utilization rate is low, have impact on the generating capacity of this equipment.
Summary of the invention
The present invention, in order to make up the defect of prior art, provides a kind of simple and reasonable, significantly reduces the water turbine automatic open-close blade of running resistance against the current.
The present invention is achieved through the following technical solutions:
A kind of water turbine automatic open-close blade, comprise arc-shaped leaf fan and be evenly arranged on the some arc shaped blades on leaf fan by rational deployment, described leaf fan is arranged in water turbine rotating shaft, it is characterized in that: the leaf fan in described two blade neutral positions is fixed with the collar, lifting bar is equipped with in the described collar, the bottom of described lifting bar is provided with pulley, it take rotating shaft as the semicircular track in the center of circle that the side against the current of water turbine lower flume is equipped with some, described track is middle part level, the selenodont that two ends are downward, blade is fixed on leaf fan by hinge.
Described lifting bar is fixed with transverse link along the framework direction of leaf fan, described transverse link is connected with one end of spanner by pull bar, the other end of described spanner is fixedly connected with blade, described pull bar is connected by spindle nose loose joint with transverse link and spanner, lifting bar is by the opening and closing of pull bar and spanner adjusting vane, when be in meet water interval time, under the impulse force of water and the effect of lifting bar pulling force, blade close; When being in interval against the current, under the impulse force of water and the effect of lifting stick force, blade opens.
Described every sheet leaf fan has m layer blade, m root transverse link, and m is more than or equal to the natural number that 1 is less than or equal to 5, and the quantity of described every layer of blade is more than or equal to 2, and horizontal rational deployment is evenly arranged on leaf fan.
For reducing the resistance of water, 70% of the described leaf fan gross area is transmission state, and the area of blade is greater than the area of leaf fan middle part transmission, so that when absorbing water, blade can ride on leaf fan.
The quantity of described each leaf fan lifting bar is identical with the quantity of track, and the corresponding track of each lifting bar, controls vaned folding.
When cyclically-varying is done in inflow direction, as tide, flood tide, at ebb tide, lower flume can be symmetrical set liftable track, i.e. upstream face, the against the current face liftable track of symmetrical laying respectively, when inflow direction changes, the track that original side is risen declines, and opposite side track rises, and the sloped transition interval of two tracks is with can the polylith hydraulic pressure support intelligent track of auto-control.
For alleviating resistance when blade rotates against the current, stop the winding of stumbling that floating debris is fanned leaf simultaneously, in the outside of blade, the edge of upper and lower tank is connected with water knockout drum, described water knockout drum is incomplete scroll casing shape manger board, can move forward and backward, when water turbine normally works under the driving of motor and gear around tank, water knockout drum is parked in inflow direction leaf fan and runs side against the current, for point water and obstruction floating debris; When carrying out flow path direction change, water knockout drum moves to direction, water side leaf fan and rotates side against the current; Before water turbine starts or when water turbine needs maintenance shut-downs, water knockout drum is parked in blade and absorbs water stressed side, and water is stopped shunting, interruption power resources, water turbine stops operating, and can play braking action to water turbine; During water turbine preparatory work, water knockout drum slowly leaves the force area that meets water, and moves to the side that blade is interval against the current, prevents blade, transmission part and generator from starting suddenly the battle array caused and quiver, shield to equipment.
The invention has the beneficial effects as follows:
1. water-control of the present invention, reduces the water turbine resistance of water between rotational area against the current, greatly improves waterpower utilization rate and generating capacity.When blade is opened, leaf is fanned almost in full impregnated dummy status, and water knockout drum stops shunting to water simultaneously, and the drag reduction more than 60% when leaf fan can be made to rotate against the current, generating capacity increases substantially.The dam Power Station Turbine that, rotating speed large relative to pressure is fast, ocean current, trend, runoff velocity are slow, and rotational speed of water turbine is low, for the design and devdlop of expanded letter water turbine automatic open-close blade provides possibility, have started the precedent of low-speed water turbine efficiency utilization water energy.
2. adaptable, generated output is large.The design can make multifunctional generating equipment utilize ocean current energy, tidal energy better, and runoff can generate electricity, and equipment all can efficiently be worked in various waters.Owing to adopting automatic open-close blade, greatly reduce resistance when blade rotates against the current, what water turbine can be made to do is enough wide, enough high, and generating capacity is strong, list portion hydraulic generator generated output can reach about 10000Kw, is obviously better than the existing equipment utilizing free water to generate electricity.
3. the present invention is novel, design is unique, very practical, is not only alleviating in the resistance of water, and in equipment self-protection, be convenient in maintenance, that all designs is thoughtful extremely to the greatest extent, both advanced, practical again.
