Description

Sail type wind-driven power device

The utility model relates to a kind of generation device of renewable energy sources, exactly, relates to a kind of sail type wind power device.

Along with the propelling of development of human society and science and technology, people's living standard also improves constantly with more and more faster speed, and along with human substance life horizontal's raising, the consumption of the energy also increases year by year, and energy resources day is becoming tight.Usually people are accustomed to using with fuel such as coal, oil, rock gases as primary energy; because this fuel of a large amount of uses; when it is for people's work done performance usefulness; also bring a kind of serious natural crisis silently; it is drained a large amount of used heat and toxic and harmful, material in physical environment, one of performance is that the carbon dioxide content that has remained balance in the atmosphere since how many centuries is increasing year by year.This balance is one of requirement of keeping the nature survival and prosperity, if let alone down by present trend development, will produce greenhouse effect in 21st century, and its consequence can seriously jeopardize human normal life.For this reason, the United Nations convenes the countries in the world head to hold " environmental development conference " in June in this year, appeals to improve as early as possible human earth environment of depending on for existence.Moreover above-mentioned mineral fuel resource is also exhausted day by day, forces the new energy of the diligent exploitation of people.Renewable energy sources paid more and more attention and development and use that solar energy, underground heat, waterpower, morning and evening tides, wind-force etc. can obtain from natural phenomenon in earth environment again and again.Wherein wind resource also is a kind of inexhaustible renewable energy sources, and again without any pollution, therefore, industrially developed country extremely pays attention to the exploitation of wind resource in recent years.At present, most wind force devices all use the wind power apparatus of similar propeller, because the grade of wind resource is extremely low, in order to obtain certain power, must do the diameter of paddle very greatly, and wind force device is set up suitable height, like this, certainly will involve great expense, safeguard and use also inconvenience.For example, the tower height that Italy succeeded in developing and soon dropped into " gamma ┈ 60 " huge wind-driven generator of trial run recently is 66 meters, and 60 meters of leaf exhibitions are also longer than the leaf exhibition of large-scale helicopter, and its manufacturing, technology of using, safeguarding all require very high.

The purpose of this utility model provides a kind of sail type wind power device of novel structure.This invention makes the paddle of traditional wind force device into the plane sail, thereby its blowing area is increased greatly, increases Wind Power Utilization efficient, and its manufacturing process is simple, uses, safeguards also very convenient, can make in common middle-size and small-size machine works and produce, for apply provide may and market.

Structural representation of the present utility model as shown in Figure 1, it includes sail 1, vertical shaft 2, coupling 6, support 5 and generator 7.The wind apparatus that is subjected to of the present utility model is radially equally distributed 3～4 wind wheels that vertical sail 1 is formed on vertical shaft 2, sail 1 is fastened on the vertical shaft 2 by the axle sleeve 3 of one side, vertical shaft 2 bottoms are fixed on the Steel Support 5 by radial-thrust bearing 4, lower shaft end at vertical shaft links to each other outputting power by coupling 6 with generator 7 or drive unit.Form in order to it is fastened on by axle sleeve 3 on the vertical shaft 2 and the several rows of louver assembly 10 in the framework by the framework 9 of rectangular shape, framework one side for sail 1, wherein each blade single-piece two ends all have a bearing pin be used for the hinge be contained in the framework 9 so that blade can freely swing with bearing pin.And a side of framework 9 be equipped with one on it with each corresponding adjusting screw rod 11 in blade 10 positions, in order to adjust the sealing angle of each blade.

Sail 2 is to be installed on the vertical shaft 2 also fastening with screw by axle sleeve 3.This sail makes lifting surface area greatly increase than the paddle of propeller formula.On vertical shaft, can radially evenly place 3～4 sails.The valve plate of the several rows of blade 10 similar one-way valves in the rectangular frame 9 of each sail is the same, when wind when the stress surface of sail blows, each blade on this sail is all in the closed position, the sail wind-engaging blows and rotates around vertical shaft.When sail was in against the wind to the position, this moment, blade all was in the enable possition, and the blade of wind from sail penetrates and mistake, sail and do not stress (or stressed very little).Blade 10 on the sail is adjusted the angle of its switching by the adjusting screw rod 11 of one side.Because the sail on the wind wheel is all installed with the same manner, therefore, no matter wind direction is from where, sail all promotes the vertical shaft rotation along same direction, and this kinetic energy reaches generator 7 or drive unit by coupling 6, produces electric energy or outputting power.

Sail in the utility model can adopt another kind of structural type, as shown in Figure 2, be the screen frame that also can form by the steel wire 12 that on rectangular framework 9, intersects in length and breadth of sail 1 and on screen frame the topped tinsel 13 that is the distribution of fish scale shape form (only having drawn part metals sheet 13 among the figure), wherein all there are two small circle rings each both sides, sheet metal 13 top, in order to wearing on the steel wire that hangs over screen frame, and to make sheet metal 13 can be that axle is swung with this steel wire 12.When sail was in the stressed position of contrary wind, air stream was close to the squamous sheet metal on the steel wire screen frame, makes sail be in stress, when sail turned to the contrary wind position, air-flow blew scale open, makes sail be in ventilative state, sail does not stress, and its working principle is identical with aforementioned structure.The sheet metal that the fish scale shape distributes can adopt the aluminum alloy manufacturing, also can make the sail sheet with some nylon cloths or canvas and be fixed on (just fixing in the top) on the screen frame, substitutes the sheet metal that the fish scale shape distributes.

Of the present utility model relatively simple for structure, the calculating of its sail does not resemble the propeller complicated, can select the area of sail according to the wind resource grade of locality, the watt level of institute's driving generator at an easy rate, its manufacturing process is not difficult yet, and cost is cheaper.Because this appliance arrangement is installed in ground, mounting, commissioning and maintenance is all very convenient, do not need special structure stand yet, greatly reduce cost, topmost characteristics then are that blowing area is all bigger than the blade of the wind force device of other any kinds, like this, even also the utility model can be installed, wind resource is fully used in the very weak area of wind resource.It is calculated that 1 kilowatt-hour of wind-power electricity generation of every use just is equivalent to discharge less 1 kilogram of carbon dioxide in atmosphere.Penetration and promotion of the present utility model is a Gospel for improving environment for human survival.

The utility model mainly is applicable to home-use small wind power plant, so sail is unfit to do too greatly.The wind wheel of being made by sail and vertical shaft is the structure of single-ended supporting, if sail makes bigger, the perhaps relatively sufficient area of wind resource, can increase supporting in vertical shaft upper end at wind wheel, just set up the gantry frame type Structural Hardware of a shaped as frame, to strengthen the rigidity and the intensity of sail vertical shaft, the blowing area of sail can be done greatly like this, and the power of its output is also just bigger.
