Description
Technical field
The present invention is a kind of, and what drag that wind-force reclaiming type electricity generating device relates on tower is on wind-force, to drag the great core technologies such as tower, the recycling of narrow pipe generating tail wind, the foundation of working medium increment window, pneumatic equipment blades made manufacture, aerodynamic force, electric energy conversion, belongs to a kind of and drags wind-force reclaiming type electricity generating device technical field on tower.
Background technique
Make a general survey of existing domestic and international wind-power electricity generation market, the leading position that horizontal-shaft wind turbine accounts for whole large market has been undisputable fact.Although also have vertical axis windmill to get into market, be only phoenix feathers and unicorn horns, be difficult to vie with each other to see who is the better with horizontal axis one, move towards the status of a sovereign, share all over the world.No matter be that horizontal axis or vertical axis windmill all exist a thorny difficult problem in various degree, hinder horizontal axis, vertical axis windmill to the degree of depth, range development.Horizontal-shaft wind turbine because its center of gravity is high, weight is large, turn to difficulty, in dangerly cannot dodge, investment repayment is low, inefficiency and transportation installation, regular maintenance, safe operation all have unsatisfactory part, and vertical axis windmill has, power is low, resistance is large, efficiency is low, be difficult to concentrate cloth field, Zhi unshared housing or among a small circle in exercise one's ability, can not form the painful topic of large climate.
Investment is large, efficiency is low, poor stability, working life are short, Maintenance Difficulty is its common problem.Various countries expert, scientific research personnel, industry warm-hearted people are all using one's brains, and strive searching out outstanding type safer, efficient, convenient, non-maintaining, long service life.Through retrieval, no matter this type of novel type is paper, or ripe type is all difficult to find, and particularly for the wake flow utilization of narrow pipe wind gathering turbo type generating, generates electricity and has never heard of especially again.
Through further retrieval and market survey, have no expert document and the patent report in full accord or similar to the present invention.
Summary of the invention
The object of the invention is the various wind driven generators learned for domestic and international existing wind-power electricity generation market and expert's document and the patent report of the third wind-power electricity generation of famine, provide a kind of and drag wind-force reclaiming type electricity generating device on tower, for coordinating novel narrow pipe wind gathering turbo type generating, carry out high speed working medium residual current is rationally recycled to generating again for object of the present invention especially.
The present invention is consulting on the basis of a large amount of technical data through this enterprise key technician, again through domestic top full-time wind-power electricity generation expert simulation, adopt the multiple technologies means such as finite element analysis, show that narrow pipe wind gathering turbine type wind power generation surplus availability is in 25% left and right, wind speed is up to more than 20 meter per seconds, therefore the present invention provides a kind of to the whole society and drags wind-force reclaiming type electricity generating device on tower, to fill up domestic and international blank.
One of feature of the present invention is the rotating regular plate technique of the incremental technology coupling wind-force of window formula air draught, according to Bernoulli's law, fireballing fluid pressure is less, near the slow fluid of flow velocity will be sucked into, with this theoretical specially designed hoop window, in the situation that narrow pipe exports 20 meter per second left and right wind speed, wind guiding tube wind energy around sucks from hoop window, thereby has improved original air quantity.According to aeronautical theory design revolve the regular plate of shape, in time sinuous flow, eddy current are divided into helical laminar flow, make wind energy collide regularly blade keypoint part and produce rotating force, drive central shaft rotation.
Two of feature is double stage tandem combination kyphosis covering of the fan blade technologies, by aeronautical theory and the 3rd theory of strength, it is design considerations, in conjunction with aerodynamics, be guidance simultaneously, adopt closed circuit method, with built-in forward and backward each one-level of cylindrical shell, series connection also coaxially arranges novel bow-backed shape covering of the fan blade, on having increased again, drags face when reaching resistance face width.Before and after covering of the fan blade dislocation layout, when air movement, fluency are improved, make again acting ability have further lifting 25%, solved traditional wind energy conversion system and the wind comes from and once cross inefficient problem.
Three of feature is to drag reinforcement technology on straight-tube " chimney ", and the two temperature heating of heat that air produces when high-speed extrusion, friction and wind turbine high speed rotating, make air and ambient windstream produce temperature difference.According to object principle of expanding with heat and contracting with cold, the gas density that temperature is high is little, and the existence of density difference certainly leads to lift upwards, forms on powerful and drags power, thereby reach the object that gentle breeze also can generate electricity with this.Can in industrial and mineral or residential quarter, directly build a station by electricity consumption mouth especially, omit a large amount of power transmission and transforming equipments and expense, ensure again the normal work of rearmounted wind wheel blade simultaneously.
