Abstract

The invention provides a simple wind driven power generation system which utilizes water as an intermediate carrier of energy and combines a multilayer wind wheel as a wind energy capture unit and a hydroelectric generating set as an electric energy generation unit. Favorable conditions are created for the large scale and the full localization of the wind driven power generation system. Therefore, the wind driven power generation system has wide development prospects.

Description

Water energy-accumulation type wind power generating system

Wind-power electricity generation is to utilize wind energy to produce the green renewable advanced method of electric energy, neither consumes fossil fuel, and is free from environmental pollution again, therefore is subjected to extensive attention.

China's wind resource is very abundant, lifts it and wants the person that the oceanic winds of dry wind, the southeastern coastal areas of the Northwest, the vast southern existing area or the like that water resources has the geographical weather conditions of wind again of enriching are arranged.According to the statistics that China relevant department delivers, China's wind resource be equivalent to the twice of China's waterpower resourses approximately, so wind-power electricity generation has very wide development space.

China recent years had once been launched exploration with considerable scale and trial to the wind-power electricity generation cause, but still was confined to introduce external technology and equipment so far, and cost is very high, and maintenance is very difficult again, can not adapt to the basic demand of China far away.Particularly the capacity of wind power system monoblock is subjected to the limitation of foreign technology, can not realize maximizing.In view of this, 12 planning of China country have just proposed the call of exploitation large-scale wind generating unit specially, to adapt to pressing for of large-scale development wind-powered electricity generation.

The core technology of patent application of the present invention proposes one and has broken away from the miniaturization pattern with propeller cavitation wind wheel drive generator that extensively adopt present home and abroad fully, but adopt independent innovative multiple layer wind wheel is the trap tool of wind energy, with water is the intermediate carrier of the energy, wind energy at first is converted into the potential energy of water, drives the hydraulic generator unit with high potential water then and produce electric energy.In this system, except the multiple layer wind wheel was inventive arrangement, other equipment all were the existing very conventional products of mature experience of China.Therefore, in case the art of this patent successful implementation, this system can realize overall production domesticization.

In the electrical transmission scheme that patent of the present invention proposed, many typhoons turbine generator group can be introduced a shared head-tank with the high pressure water that it produced, the high pressure water of a head-tank drives a hydraulic generator unit, also can drive many hydraulic generator units.Also be not precluded within the large-scale wind power plant, strong in number because of the wind wheel generation unit, can separately high pressure water be injected a plurality of head-tanks, separately generating.Therefore this compound mode is very flexible, very is suitable for the design of various scale wind energy turbine set.

Fig. 1 shows the layout schematic representation of water energy-accumulation type wind power generating device (electrical transmission scheme).Wind wheel among the figure (1) is subjected to the promotion of wind-force head-on and rotates, and drives generator (2) and produces electric energy, is directly used in and drives electronic high-pressure water pump (4).This pump is drawn the low potential energy water in the low pool (5), becomes high pressure water, injects head-tank (7) by water inlet (6).High potential water in the head-tank leads to hydraulic generator unit (10) with sewer, produces electric energy, outwards output.

Fig. 2 shows the structural representation of the multiple layer wind wheel (1) that this patent proposes, and (part 13) is the wind wheel center hub, around it, has laid several concentric wind wheel circles (14).Arrange several fins (20) between two adjacent wind wheel circles.The fin of each circle is similar basically, but the fin number of each circle is then done the variation of proportionality along with the distance of this wind wheel circle distance center hub, fin (20) has an inclination alpha, so head-on wind is when touching fin, a change has taken place in wind direction, thereby has produced one along the tangential component of wind wheel.Here it is makes wind wheel rotate the source of mechanical energy.

The maximization of seeking the wind-power electricity generation unit is that China's Business circle are sought hope for a long time, once repeatedly to global position vacant technical support, but all fails satisfied process.Trace it to its cause, learning that external scientific and technological circle cannot forget for the design of wind wheel drags the beautiful sight in small-sized workshop, mill and so in Europe some country (for example Denmark, Holland) windmill of widely using in Middle Ages, concentrate on the improvement of Design of Propeller simply, think that this is the only magic weapon that utilizes wind energy, thereby also just be difficult to break away from the category of miniaturization.

The multiple layer wind wheel is a brand-new things, the business people that the applicant suggestion intends to implement this new technology, should be with reference to the development Experience of thermoelectricity, water power and nuclear power, at first build a strong scientific research design organization (institute), to the design of maximization wind energy turbine set, the every aspect of particularly above-mentioned multiple layer wind wheel is carried out deep scientific approach.Applicant is thought and is weighed the achieving success of can showing one's talent by the existing science and technology strength of China.

Special suggestion:

Present patent application and the preceding patent application that has proposed 200610067799.1 " water energy-accumulation type wind power generating system and corollary new equipment thereof " are different Qu Tonggong, the former is the mechanical transfer scheme, present patent application then is the electrical transmission scheme, common is two different schemes of design proposition of water energy-accumulation type wind energy turbine set, so can think that two patent of invention are companion volumes, it organically combines the overall plan that has just proposed a complete skill for water energy-accumulation type wind energy turbine set technology.Would like to ask the parties concerned pays close attention.

Claims

1. patent of the present invention (water energy-accumulation type wind power generating system) adopts water to promote hydraulic generator unit generation electric energy as the intermediate carrier of energy, and in the electrical transmission scheme, wind wheel drives generator. directly drive electronic high-pressure water pump to produce high pressure water; After high pressure water injects head-tank, drive the hydraulic generator unit by sewer and produce electric energy, see figure (1), its feature has:

1. adopt multiple layer wind wheel (1), directly drive generator (2);

2. the electric energy that produced of generator (2) is in order to drive electronic high-pressure water pump (3), and water pump is said low pool (4) and drawn low-pressure water, produces high pressure water, injects head-tank (6) by high-pressure water pipe (5);
