Description

Rotary wing type windmill and its load

Technical field: the invention belongs to technology field of wind utilization.

Background technique:

Wind energy is a kind of non-pollution of renewable energy of cleaning.Large-scale development and use wind resource is the ideal that people pursue always.

, people not only can not effectively be used to wind energy at present, also are subjected to the injury of disaster caused by a windstorm, sandstorm and dust and sand weather often.

Problem goes out on present oar blade type wind-driven generator.

What it adopted is a kind of high trestle structure.Its head, blade, generator, tail vane all will be installed in the top of high trestle, and this has just formed a kind of lever construction that very easily is blown over by the wind, and its blade also is a kind ofly easily to be scraped disconnected long lever structure by wind.It also adopts the structure of two main shafts.That is: a blade main shaft is responsible for the rotation of head and blade.Another root is the wind direction axle, is responsible for making head to aim at wind direction.This root wind direction axle also will be responsible for supporting the weight of whole head, blade, generator and tail vane.

More than these two kinds of structures make and seem that simple windmill is in fact very complicated.In order to increase its wind resistance power, people have to spend expensive, make it with special material.This just makes the cost of every kilowatt of wind-driven generator more than 1,000 dollars.This input has exceeded more than a times of steam power plant.

Even so also can't sail right before the wind, it also needs special vacant lot and could install.After having installed, its maintenance has become difficulty again.Head, blade, generator are all on the top of high trestle, and the difficulty of maintenance is just well imagined.

The cost of great number, maintenance highly difficult limited applying of oar blade type wind-driven generator greatly.It is exactly clear proof that its track is difficult to find in many windy places.

Summary of the invention: the present invention will solve the problems of the technologies described above exactly.

The technological scheme that adopts is as follows:

We know that capstan winch is that a kind of bearing specially pretended firmly and the structure of good stability.

The fondational structure of rotary wing type windmill is exactly a capstan winch.Substitute the high trestle structure with the capstan winch structure, just make the rotary wing type windmill that good rated wind velocity is not only arranged, can also save the expense of support widely.

The rotor windmill does not adopt expensive blade, but is covered with valve on the surface of rotor.Valve on the rotor is by framework and radial arm bearing.So just make whole rotor that good wind resistance is arranged.

We know the wing of bird when moving upward, and its feather can open automatically, and air will leak from the gap of feather in the past, and air is just very little to the active force of pinion.The wing of bird is when moving downward, and feather will auto-closing, and air will be blocked by feather, and air will produce a masterpiece that makes progress and be used on the pinion, and bird will rise.

As can be seen, the upper and lower surfaces of pinion are antipodal to the effect of air.A face is to leak, and another face is a retaining.This is the ingenious part of pinion just.

Valve on the rotary wing type windmill is as feather, rotor is also just as pinion, and its two faces also have different functions: one of them face wind-engaging masterpiece time spent, valve can all be opened, wind will leak from the gap of valve, and wind is just very little to the active force of this face; When another face wind-engaging masterpiece time spent, valve will be all closed, and wind will be blocked, and wind-force will act on the whole rotor.

This effect of keeping out the wind and the effect of leaking out also produce a benefit simultaneously, and it makes the rotary wing type windmill have the function of automatic identification wind direction.This has just saved wind direction axle and wind direction rudder on the oar blade type windmill again.

The mounting type of rotary wing type windmill is also very flexible, and it not only can be installed in spacious place, and mainly is the side and the top that can be installed in building.

Its load can be installed on the ground, on the surface of building, or even the inside of building.This just makes windmill and load be more convenient for using, keep in repair and maintenance.

The oar blade type windmill can only drive a loaded work piece, also must shutdown protection wind-driven generator when running into high wind.

The rotary wing type windmill can have the mode of several driving loads: wind hour, and it can only drive a less loaded work piece, along with the reinforcement of wind-force, can increase the number of its load gradually; During high wind, it can drive several the bigger loads of power and work simultaneously.Windmill of this usefulness drives the pattern of several loaded work pieces simultaneously, the inevitable cost that reduces Wind Power Utilization widely.

Embodiment:

Contrast accompanying drawing 1 and accompanying drawing 2.The rotary wing type windmill is made up of pedestal (1), main shaft (2), spiral arm (3), framework (4), little axle (5), blade (6), speed change gear (7), load (8).One little and valve of fan leaf composition, every group of spiral arm, framework, valve are formed a fan rotor.

The windmill of these two kinds of structures has a common feature: so long as perpendicular to the wind of main shaft to windmill, windmill just can rotate.Under this prerequisite, these two kinds of windmills can be installed in the side and the top of building.

Contrast accompanying drawing 1, the main shaft of rotary wing type windmill has passed the wall of building, and main shaft drives several loaded work pieces in the inside of building by a cover speed change gear.

Contrast accompanying drawing 2 changes sooner in order to make the rotary wing type windmill, its spiral arm can be done shortly, and main shaft is done longerly.Because main shaft is longer, in order to increase wind resistance power, the two ends of main shaft all have the bearing object supporting respectively.One end of main shaft is through the direction of helical gear speed change gear change main shaft, with the inside of transport of kinetic energy to building.Certainly can also be by other speed change gear with transport of kinetic energy to indoor.As can be with a cover belt pulley or the toothed chain bar carries out transmission.Certainly accompanying drawing 1 can also be connected on the top use of accompanying drawing 2.The windmill of several accompanying drawings 2 also can couple together forms the use of windmill group.

For the working principle of rotary wing type windmill is described better, drawn accompanying drawing 3.With reference to accompanying drawing 1, accompanying drawing 3 has adopted plan view.In order to see clearlyer, accompanying drawing 3 has adopted the sectional view that top is cutd open again.

Arrow among the figure is represented the direction of wind, and the windmill in last figure below is a same windmill.The difference of last figure below has been a change of the wind mainly.

This figure is noted that: the passive with the wind folding of the valve energy on the rotor.The open rotor of valve, wind just leaks in the past, and wind is just little to the active force of rotor.The rotor of valve closure, wind is just blocked by valve, and wind is just big to the active force of rotor.The force action of three rotors is on main shaft, and windmill will turn clockwise.

It can also be seen that from figure when same windmill, the upper right blows in being subjected to last figure wind, windmill turns clockwise.In figure below, change of the wind, when left blew, windmill still turned clockwise.What windmill was described turns to wind-engaging not to the influence that changes.

It can also be seen that from figure: there is the effect of well going for a drive the outer of framework than broad.

Accompanying drawing 4 is stereograms, and what its pedestal adopted is one section sleeve pipe, and casing pipe sleeve is fixed on sleeve pipe on the corner then in the main shaft outside.In order to see to such an extent that know that more main shaft also is not inserted into the end.

Optimal way:

The present invention can have multiple optimum organization, only lifts several examples below and is illustrated:

1, solve the warming problem for school:

The cold day in winter is accompanied by strong wind weather often, and the many places of school's wind are arrived in the stack mounting of this windmill and generator, and windmill just can drive several generator for electricity generation.Because the fed distance of electric energy is short, just do not need high voltage power transmission, can make generator send low-voltage safety in design.Electric energy can be transported in the boiler of school, also can be delivered directly on the electric heating apparatus in classroom, so just can allow students use the heat energy of cheap safety in the winter time.

Same combination also can be installed in the many places of building wind and gather wind energy, for electric water heater, electric heating provide the electric heating energy.Can provide heat energy for family, green house of vegetables, the plant in rural area, also can use for family, hotel, the factory in city.

2, the electric power that sends of wind-driven generator can brine electrolysis, low-cost system oxygen, hydrogen manufacturing.Oxygen can be industrial, medical and civilian.Cheap hydrogen can be accelerated the exploitation and the use of hydrogen powered vehicle, and hydrogen powered vehicle has been popularized, and just can fundamentally eliminate the pollution of atmosphere in city.

3, present sewage disposal device all is to lean on operation power, and its operating cost is very high.What mounted equipment often moved is not very well, is very disadvantageous to environmental protection.

Can manufacture and design the sewage pump that the rotary wing type windmill drives, this equipment manufacturing cost is low, and operating cost is low, and enterprise just is ready to accept, and just is of great benefit to administering to pollute.

4, project of South-to-North water diversion is transported to the middle electric power pumping station that will build tens grades, the north with Yangtze River Water.Each ton water all will pass through such tens times lifting process, and this cost is very high.Can manufacture and design the large scale wind lift pump, replace electric power to pump up water with wind-force.

5, the benefit therefrom obtained of factory is just more, and factory not only can make the wind energy facility of own needs, is production and the service for life of oneself.And the corresponding wind energy equipment of Development and Production offers society energetically.Both can be social progress and contributed, and can be the worker again and create considerable economic.
