Description

Wind generating unit

Technical field

The relevant a kind of wind generating unit of the present invention, You Zhike guarantee the to generate electricity wind generating unit of function performance electricity generate function.

Background technique

The facility of people's life is visitd the application of electric power entirely and is grant; It is whether complete that electric power is united; Whether be progressive leading indicator, so national governments drop into great mental and physical efforts, the vital functions that the abundant supply of expectation power supply comes to have convenience to the people invariably for the exploitation of power supply if evaluating this zone often.

So, as the crowd knew; The generation of power supply mainly contains several generation modes such as thermal power generation, hydroelectric power, wind-power electricity generation and nuclear energy power generation and produces electric power, and wherein thermal power generation is a fuel with natural resources such as coal or rock gas or fuel oils mainly, as the basic material of generating; Yet the pollution of the carbon dioxide of its generation of thermal power generation and ashes etc.; For people's the healthy injury that causes, be problem very serious in the modern public hazards, and this coal or the exhaustion day by day already of natural resources such as rock gas or fuel oil; Therefore cause the cost of thermal power generation also increasingly high, so the thermal power generation mode is gradually in eliminating.

In addition, the nuclear energy power generation mode no doubt can provide at a low price and cleaner power supply; But the nuclear radiation that this nuclear energy power generation produced is polluted; Since present human science and technology can't be effectively with solution completely; Therefore the nuclear energy power generation mode usually causes dispute greatly in the environmental protection, is with the also non-more feasible mode of nuclear energy power generation mode.

Yet, with feature of environmental protection problem, the green doubt that can generation mode more can not produce environmental pollution such as hydroelectric power and wind-power electricity generation adds under the situation that the natural resources of the earth day by day reduce; Therefore, the green ability of this kind and forever the mode of supervention electricity be that present national governments all actively drop into the project researched and developed of participating in; Yet two kinds of generation modes of this hydroelectric power and wind-power electricity generation; Because the water resources of institute's palpus in the hydroelectric power; Be a kind of unsettled energy of source electrode that comes, generate electricity, often cause the holocaust of ground environment as obtaining stable water resources; Can cause CR Critical injury for ball ecological environment, so the hydroelectric power mode also exists very big environmental protection and problem easily inadequately; And wind to be the earth form naturally, and can therefore how to utilize the mobile naturally wind-force of earth surface to generate electricity in the flowing of earth table nature, be the very most important construction problems of present national governments.

Be how a kind of effective wind generating unit is provided, a big problem that has needed to be resolved hurrily for present industrial circle.
