Description

Be used for wind-force or hydroelectric device

Technical field

The utility model relates to a kind of wind-force or hydroelectric device of can be used in.Belong to renewable energy sources (wind energy, flowing water ability, tidal energy) technical field of power generation.

Background technique

The primary energy that can exhaust in recent years, has presented its problem that is difficult to continue forever one after another.The high enterprise of oil oil price causes the threat of war to appear at one after another in produce oil ground or the petroleum transported way; The difficulty of coal is demonstrated one's courage and power to people with mine disaster, pollution of atmosphere with property one after another.This caused people have to turn one's attention to again cleaning can be lasting the energy---solar energy, tidal energy, place hope on effective transformation of energy device and switching material.

Wind energy, elevated reservoir, lasting flowing water all come from solar energy.Because the nonuniformity of solar energy radiation effects has caused flowing of air promptly to form wind; The solar energy radiation also gets into the high-altitude with the water evaporation in ocean, the earth, lake and the river, arrives the mountain region, plateau to moisture vapor transport through wind then, revert to the highland through rainfall again, forms day and night untiring river then.People build dam (also can form naturally certainly, like high mountain lake, seimic barrier lake) blocking-up river, have formed elevated reservoir.All these have caused empty G&W always directionally to flow in certain moment.

The empty G&W of these directional flow certainly promotes the mechanical orientation motion, also just can easily energy-producing conversion.In the human occasion that can control, electric energy is most popular form of energy.Therefore panoramic wind-force and hydroelectric generator arise at the historic moment.

Comparatively speaking, hydroelectric generator is generally used in the elevated reservoir power generating equipment, and form is more single.Because the control ratio of current is easier to, its difference possibly mainly be size.Yet, for wind-driven generator,, caused blower fan various informative because wind is difficult to control, vary in size.Modal blower fan roughly is divided into two types, i.e. vertical shaft and horizontal axis wind-driven generator.

The wind wheel running shaft of vertical shaft and horizontal axis wind-driven generator is respectively vertical and level.Now, horizontal axis wind-driven generator generally is used for the large-scale wind power field in wilderness, and its installed power is all very big.Its advantage is that energy conversion efficiency is high, and shortcoming has noise bigger, and is unfriendly to birds; Therefore vertical axis aerogenerator is just opposite, is applicable to also can be used for the backvelder away from electrical network in the place that the cities and towns signs of human habitation are intensive, replenishes as of electricity network, helps energy-saving and emission-reduction, benefits the society.

The design of existing multiple vertical axis aerogenerator.They generally are single wind wheels, but the design (like US 6942454, CN 201020196381.2) of a pair of wind wheel is also arranged in the document.With respect to single wind wheel design, two wind wheels rely on anterior air guide sleeve to focus on more wind energy on the wind wheel blade, and rely on it to block effect, reduce the blade resistance when motion against the wind effectively, and therefore two wind wheel designs can increase energy conversion efficiency.

The utility model is a kind of two (many) runners wind-force (waterpower) generator, can be used for the wind-power electricity generation of hinterland, also can be used for the hydroelectric power of beach, river bank.We can say that as long as the place that has fluid to flow, the device that the utility model is announced just can use.

For fluid energy is converged on the outer foil of runner efficiently, cowling is made fairshaped especially.Can partly lose the influence of the turbulent flow of (because transformation of energy) generation afterwards to the runner rotation in order to reduce fluid, the rear portion of runner also will add a fairshaped cover.This cover protects transmission device not receive the erosion of air and current simultaneously.The number of the blade of runner can be like 4 among Fig. 1, also can be the sheet numbers of 3,5 or other number; The shape of blade can be shown in Fig. 5 a and 5b with the coplanar straight plate of rotating shaft, also can be like Fig. 5 c and bottom and the angled straight plate of rotating shaft, also to be a plurality of combined blades that damping is rotated that carry out that have shown in Fig. 5 d; Can also give the blade of the blade shown in Fig. 5 a and the 5b or other shape with Fig. 5 c and 5d characteristics, to obtain the highest energy conversion efficiency.It depends on the application, depends on fluid dynamic requirement, and purpose is to make the device energy conversion efficiency the highest.

2. practical implementation step:

This electricity generating device can be used for having the various occasions of flowing fluid, and its allocation method also depends on the requirement of occasion.In different use occasions, the parts of device can optionally remove or increase, and the position of generator also can place the correct position of device symmetry plane, so that whole device stablized, and can build cheaply.

Below for giving an example by the design preferred version of different use occasion summaries.

Embodiment 1: be used for the hydroelectric generator on the seabeach

When this device is placed in the seabeach because rise, during ebb tide the direction of current be two to, device as shown in Figure 2 is fixed on the pedestal, head surface comes the direction of water to the sea.Like this, when fluid when the head of electricity generating device or afterbody flow, two runners all can drive the generator amature generating to same direction rotation then.

Embodiment 2: the hydroelectric generator that is used for the river

When this device was used to the edge, river, because the direction of current is fixed, device was fixed on the pedestal, and removed the shutter at rear portion.Because one side water velocity near the riverbank maybe be very little; The size of two runners can be different to obtain suitable thrust; Also can remove that runner by the riverbank, in addition remove half the and generator is directly linked with runner by on one side that of riverbank, with the lower cost of acquisition.

When central authorities use in the river; The velocity field of current is evenly distributed; Therefore can remove the front and back shutter among Fig. 2; Only stay the outer cover that plays water conservancy diversion and protective action (for for the purpose of clear, not drawing among the figure) and the afterbody guide plate at cowling, runner rear, make a fish shape device (as shown in Figure 1) that can swim on the water surface.The rope that device will be anchored on the riverbed holds.Can be passed to the river bank user to electric power through the river bed cable, perhaps only give korneforos navigation mark tutorial light power supply.

Embodiment 3: high altitude wind power generator

Wind generating unit as shown in Figure 1 has the aerodynamic profile of the kite of meeting, so that it swims in the high-altitude.The blade of wind wheel can design (as having the shape shown in Fig. 5 c) especially, and makes the inclination angle appropriate change of the horizontal guide plate of empennage, makes device in wind, produce lift automatically, thereby can float on aerial with booting.The electricity that sends can be led ground with (storage) electrical equipment through the traction rope of device.

Embodiment 4: be used for the wind-driven generator near the face of land

The wind that approaches the face of land comes to indefinite, but its moving direction generally is parallel to ground.Therefore, in use, the electricity generating device that is similar to Fig. 1 is placed in its position of centre of gravity, perpendicular in the ground and the rotating shaft that can rotate freely.Like this because the effect of afterbody guide plate, the head of electricity generating device can automatically face all the time wind come to.

Embodiment 5: wind-force (or waterpower) generator with 3 or 4 runners

The electricity generating device of the utility model also can be installed the runner more than 2 on the basis of device shown in Figure 1, be used for the uniform occasion of fluid momentum field pattern and generate electricity.The runner rotating shaft that increases is vertical with aforesaid existing two runner rotating shafts, places the top and/or the appropriate location, bottom of device respectively, and the gear transmission that causes is shown in Fig. 4 b.

Such arrangement has following benefit: if having only 3 runners, then the 3rd runner can be placed in the top or the bottom of device.The 3rd runner places the electricity generating device on top can be used for the high altitude wind generating; Because like this; Electricity generating device not only can utilize the wind energy of electricity generating device top, but also can utilize Magnus effect (Magnus effect) to produce lift, and device is floated aloft more easily; The 3rd runner places the electricity generating device of bottom then can be used for the hydroelectric power of river central authorities, because the top of device possibly not have current to pass through.At this moment, Magnus effect (Magnus effect) can produce a power that lets device sink, but this effect can be offset through the design that changes anterior cowling.

Certainly, also can pacify and ranked fourth runner.See past tense so from the head, the rotating shaft of four runners has just constituted a rectangular, and this helps fluid can comprehensive absorption.Through the suitable design to cowling and empennage guide plate (cover), device can be used for wind-force or submersible type hydroelectric power.
