Abstract
The utility model discloses a jellyfish type water turbine. The jellyfish type water turbine comprises a rotor which is installed to be capable of rotating around an axis; the rotor comprises blades, an inner ring and an outer ring; the blades are arranged between the inner ring and the outer ring so that the rotor can rotate around the axis where the inner ring is located when the blades are located in flowing water; blade fixing shafts are arranged on the blades and arranged between the inner ring and the outer ring; unfixed parts of the blades serve as elastic adjustment areas, wherein the elastic adjustment areas automatically change the angle of the unfixed parts of the blades according to different impacts of water flow on the blades. According to the jellyfish type water turbine, the angle of the lower portions of the blades is changed automatically under the action of elastic force and flexibility so as to compensate for instability caused by changes in the impact force; the stability of the rotating speed of the water turbine is improved, the stability of the voltage and frequency of a hydraulic turbine generator can be ensured, and therefore the hydraulic turbine generator is wider in flow velocity application range and higher in efficiency; blade adjusting shafts are used for adjusting the best angle of the blades, and therefore the angle can be more convenient to select.
Description
Technical field
The utility model relates to a kind of turbine, particularly a kind of for extract the water turbine of natural energy from current.
Background technique
The much equipment that can be used for extracting energy from current is arranged now, usually adopt water turbine, each water turbine has two or more blades, but the angle of blade is normally changeless, when water velocity changes, change angle if need and make water turbine realize the optimum operation effect, the huge assisting agency of more complicated must be set, can realize that blade rotation changes angle and realizes the optimum operation effect.Relatively large hydraulic turbine generator has enough spaces, and the assisting agency that Kaplan changes angle is installed; Other a little bit smaller hydraulic turbine generator, basic just without enough spaces, the assisting agency that Kaplan changes angle is installed.Therefore, the conventional small water turbine is all fixed blades, in the flowing water changed in flow velocity, impact force, is difficult to realize the optimal power generation effect.
Therefore be badly in need of a kind of inexpensive water turbine of turbine efficiency that improves.
The model utility content
In view of this, technical problem to be solved in the utility model is to provide a kind of inexpensive water turbine of turbine efficiency that improves.
The purpose of this utility model is achieved in that
The jellyfish type water turbine that the utility model provides comprises and is mounted to the rotor that can rotate around axis that described rotor comprises blade, inner ring and outer ring; Described blade is arranged between inner ring and outer ring, when blade is arranged in mobile water, makes rotor around the rotation of inner ring place axis, on described blade, is provided with blade fixed axle, and described blade fixed axle is arranged between inner ring and outer ring; Described blade not standing part is the flexible adjustment district, and described flexible adjustment district changes the not angle of standing part of blade according to current automatically to blade impact force difference.
Further, described vane thickness is top axis place therefrom, and upwards lower edge is gradually thin streamline variation.
Further, described blade is ellipticity, and cross section is wing shapes.
Further, also comprise the axle of the blade adjustments for the adjusting vane angle be arranged on outer ring.
The utility model has the advantage of: the utility model adopts the not standing part on the blade be arranged between inner ring and outer ring to set up the flexible adjustment district, makes this flexible adjustment district automatically to change the not angle of standing part of blade to blade impact force difference according to current.Therefore, under the elasticity and pliability effect of blade, automatically change the angle of blade bottom, it is unstable that the variation of compensation impact force causes.Improve the speed stability of water turbine, thereby guaranteed voltage, frequency stable of hydraulic turbine generator; For this reason, the applicable flow rates of hydraulic turbine generator is wider, and efficiency is higher; Carry out the best angle of adjusting vane by the blade adjustments axle, make the selection of angle more convenient.
