The purpose of this utility model is achieved in that
Comprise by upper plate, lower shoe and be connected in the framework that the strut between the upper and lower bottom plate is formed, on, three Positioning Gears are all arranged on the lower shoe, a synchromesh gear and four Tension gear, the locating tooth wheel shaft of Positioning Gear is connected with framework by bearing, band or chain are wrapped in and form rhombus blade orbit on Positioning Gear and the synchromesh gear synchronously, on, synchromesh gear on the lower shoe connects by synchronizing shaft, synchronizing shaft then is connected with framework by pair of bearings, four Tension gear are by axle and bearing and frame fixation, the two ends of sharf are separately fixed at the corresponding position of synchronous band, a plurality of blades are arranged along band is circumferentially even synchronously, synchromesh gear is meshed with overdrive gear, and overdrive gear drives generator.
The utility model can also comprise:
1, sharf inside is provided with position-limit mechanism, and blade can rotate freely in the scope of limited drift angle around sharf.
2, between the axle of Tension gear and the framework spring is set and constitutes the resilient bearing supporting structure.
According to the water turbine sorting technique, the rhombus water turbine also belongs to horizontal shaft water-turbine, also can utilize the hydrodynamic performance of angle of attack variation rule control water turbine, but with the blade movement track for circular traditional horizontal shaft water-turbine different be, its blade movement track was the straightway of parallel and equal in length before and after both can being, both sides are cambered outwards semicircle, also can be rhombus or " ◇ ".Under the current impetus, one group of blade drives rotor rotation along above-mentioned orbiting motion by certain Placement, and then drives generator for electricity generation, and trend or ocean current kinetic energy are converted into electric energy.The blade of rhombus water turbine under the fluid impact effect not only along orbiting motion, blade itself also can rotate the variation that realizes the angle of attack around self rotating shaft according to certain rules, good angle of attack variation rule can make water turbine also have good self-starting performance when hanging down flow velocity, and capacity usage ratio is higher, particularly in low speed than the time efficient not low yet.
The rhombus water turbine is compared with traditional horizontal shaft water-turbine, belongs to an innovation greatly on structural type, and major advantage is as follows:
1. down long-pending at identical fluoran stream surface, the blade track girth of rhombus water turbine is littler than horizontal shaft water-turbine, absorbs same energy rhombus water turbine material requested still less, and cost is lower.
2. according to the hydrodynamic performance result of calculation of horizontal shaft water-turbine, find that the instantaneous power of horizontal shaft water-turbine rotor rotation in one week mainly concentrates on by in the 30 degree angles about the incoming flow line of direction of main shaft, rhombus water turbine blade movement track in this section occupies very big proportion, the instantaneous energy utilization increases, so the capacity usage ratio of rhombus hydroturbine rotor is improved.
3. the track of rhombus water turbine is a straight line, and hydrodynamic characterisitic changes mild, and a plurality of blades can guarantee the smooth running of whole system along the even distribution of track.Improve the anti-fatigue performance of whole device.
4. blade adopts limit-type passive change angle of attack control technique, and the blade control mechanism is simple and reliable, and blade is under hydrodynamic effect, and blade can be adjusted to best hydrodynamic force drift angle automatically, when having improved efficient, has better adapted to the bidirectional characteristic of trend.
The utility model provides a kind of electricity generating device that can more high-effect receipts fluid dynamic energy.The renewable energy sources that provides cleaning for people's production and life.
Main feature of the present utility model is embodied in: the blade movement track is a rhombus; Adopt limit-type passive change angle of attack blade, the blade control mechanism is simple and reliable, the energy utilization efficiency height; Whole device does not have other axle systems and exists except synchronizing shaft in the blade working zone, reduced the dash effect of axle system.
The beneficial effects of the utility model are mainly reflected in: can be electric energy output easily with ocean trend, river (wind-force) kinetic energy effective conversion.Compare the capacity usage ratio height with existing vertical shaft water wheels (wind-force) unit, the fluoran stream surface of impeller can send more high-power when long-pending identical.Suitable especially large scale structure, the i.e. large-scale vertical unit of MW class made.Because the raising of capacity usage ratio has overcome the low shortcoming of structural type capacity usage ratio in the past, will promote the commerce application that trend energy, water (wind) can generate electricity.
