Abstract
The utility model discloses a streamline body blade hydraulic turbine, which aims at providing a streamline body blade hydraulic turbine which can directly use various natural fluids to generate energy without the need of a potential energy dam and extra device investment, without harm to ecological balance and need to set an inlet and an outlet of the natural fluids. The hydraulic turbine comprises a frame (1), an output shaft (2) and a water wheel (3); the water wheel (3) consists of two shell plates (8) and at least three blades (4); the blades (4) are arranged between the two shell plates (8) through a rotating shaft (5); the blades (4) can rotate around the rotating shaft (5); from the outer edge of the two shell plates (8), an external limit lever (6) and an internal limit lever (7) which are used for limiting the rotating angle of the blades (4) are sequentially and fixedly arranged on the two shell plates (8) which are on the same side with the rotating shaft (5). The hydraulic turbine is suitable for generating electricity by using sea wave, tide, wind power, rivers and natural hydraulic power of mountainous areas, etc.
Description
Technical field
The utility model relates to a kind of water turbine, particularly relates to a kind of streamlined blade water turbine that can work in wind-force and various natural fluid.
Background technique
At present, all at the energy of the sustainable use of seeking green cleaning, replacing influences the firepower of the atmosphere environment energy in the whole world.Utilizing wind-force and hydroelectric power, can reduce the pollution of year to atmosphere, is the direction of various countries' research.Water turbine with hydro powered is an example, and it is mainly constructed and is divided into water bucket type substantially, jet-type and turbo type, and hydroelectric power plant must be built dam and reservoir, utilizes the potential energy of water to promote the generating of water turbine drive generator set then.The water turbine of above-mentioned structure has the following disadvantages: (1) large-scale water wheels unit also needs the potential energy embankment except self and corollary equipment involve great expense, its investment is very huge; (2) barrage is built a dam, and has both destroyed ecotope, has also wasted a large amount of water resources, and the picture Three Gorges, and the location, resource storehouse of Ge Zhou Ba neither at will just can be found; (3) potential energy water gateway is fixed.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, a kind of do not need potential energy dam and extra equipment investment are provided, do not destroy the ecological balance, do not need to set the import and export of natural fluid, just can directly utilize the energy-producing streamlined blade water turbine of various natural fluids.
The purpose of this utility model is achieved by following technical proposals: comprise support, output shaft, water wheels, described water wheels are made up of two coverboards and two blades at least, blade pass is crossed rotating shaft and is installed between two coverboards, and blade can rotate around the axis, with two coverboards of rotating shaft homonymy on, since the outer rim of two coverboards, order is mounted with limit blade the rotate around the axis outer position-limited lever and the interior position-limited lever of angle.
Described blade is a wing shape fairing plank frame.
Described rotating shaft can be fixed between two coverboards, and blade and rotating shaft are hinged; Perhaps blade is fixedlyed connected with rotating shaft, and the rotating shaft two ends are by two coverboard clampings and form hinged.
Compared with prior art, the utlity model has following advantage: simple in structure, without any need for the extras investment, it is random good to install, environmental protection.Be fit to utilize wave, morning and evening tides, wind-force, generating such as the natural waterpower in rivers and mountain area is used.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model water wheels.
Among the figure: 1-support, 2-output shaft, 3-water wheels, 4-blade, 5-rotating shaft, the outer position-limited lever of 6-, position-limited lever in the 7-, 8-coverboard.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
With reference to the accompanying drawings 1 and 2: streamlined blade water turbine is made up of support 1, output shaft 2, water wheels 3.Main points of the present utility model are that water wheels 3 have been done technical improvement, that is: described water wheels 3 are by two coverboards 8 be made up of three blades 4 at least, blade 4 is installed between two coverboards 8 by rotating shaft 5, blade 4 can 5 rotate around the shaft, with two coverboards 8 of rotating shaft 5 homonymies on, since the outer rim of two coverboards 8, order is mounted with the limit blade 4 outer position-limited lever 6 and the interior position-limited lever 7 of 5 rotation angles around the shaft.
Described blade 4 is for being wing shape fairing plank frame.
Described rotating shaft 5 can be to be fixed between two coverboards 8, and blade 4 is hinged with rotating shaft 5; Perhaps blade 4 is fixedlyed connected with rotating shaft 5, and rotating shaft 5 two ends are by two coverboard 8 clampings and form hinged.
No matter fluid to which direction flows, and streamlined blade water turbine is all the time towards a direction rotation, if water wheels are turned over turnback around horizontal axis, streamlined blade water turbine is rotation to another way all the time.
No matter be gas or liquid,, just can promote streamlined blade water turbine and drive the generator set generating, perhaps do other things as long as certain flow is arranged.
Working principle: suppose that at first fluid flows towards a fixing direction.When the front of blade 4 is subjected to the thrust of fluid, blade 4 rotates, and the inside position-limited lever 7 of its afterbody is drawn close and be supported, at this moment, fluid is exerted pressure to blade 4, this pressure promotes water wheels 3 and rotates towards a fixed-direction, and when water wheels 3 continued rotation, the upstream face of blade 4 changed, the back side of blade 4 meets water when water wheels 3 turn to a certain angle, at this moment blade 4 rotates, position-limited lever 7 in its afterbody breaks away from, and head rotates outside position-limited lever 6 and obtains the support of outer position-limited lever 6.Blade 4 does not produce any resistance to water wheels 3 in above-mentioned rotation process.Water wheels 3 continue rotation, because blade 4 is a wing shape fairing plank frame, as the wing of aircraft, produce lift in fluid, so water wheels 3 are not produced any resistance yet.Water wheels 3 continue rotation, take blade 4 to begin to narrate most position again, begin the rotation in next week.
