Abstract

The utility model relates to a jet-tube-typed aerogenerator belonging to the wind-energy power generation technical field, which adopts the technical proposal that the jet-tube-typed aerogenerator comprises a jet tube, a generator unit, a wind-direction rudder, a connection element, etc. Using the fluid property that in the normal status the flow-speed and the cross section is inversed with the cross section when the fluid with the same flow rate passes through different cross sections, the jet tube is designed into the horn shape. The jet tube is reduced gradually from the jet-tube port to a throat port; the area of the jet-tube port is larger than the cross section of the throat port; the expansion pipe from the throat port to the tail end of the jet tube can effectively reduce the loss of the air-stream kinetic energy. When the flow-speed of the low-speed wind that flows into the jet-tube port is increased, the generator blade that is arranged at the throat port part rotates rapidly under the driving of the wind force, thereby realizing the electric power generation with the micro wind. The generator not only can use one jet tube to generate the electric power independently, but also can assemble a plurality of the jet tubes of the wind-fore generator to improve the electric power generation capacity. The aerogenerator has the advantages of small volume, light weight, simple structure, low manufacturing cost, good utilization effect, wide application area, etc. and the aerogenerator develops new way for the application of the wind energy in the places with less wind.

Description

The jet tube wind-driven generator

Technical field

The utility model belongs to the wind energy power technology field, is specifically related to a kind of jet tube wind-driven generator.

Background technique

Along with the increase in demand of the highly developed of industry and people's daily life, the international energy problem of shortage is day by day outstanding.With this both economic, the pollution-free and inexhaustible natural resources generating of wind-force, become the approach that each country taps a new source of energy.Present wind-driven generator mostly can only suit to use in the area of wind regime abundance, wind concentration, as be applied in wind-force is little, wind speed is low area just can't normal power generation, bring bigger narrow limitation to making full use of of wind-force natural resources.

Summary of the invention

The purpose of this utility model is to overcome the above-mentioned shortcoming and defect of existing in prior technology, provides a kind of and can improve ambient wind velocity exponentially, and the jet tube wind-driven generator that breezes up makes the wind energy in the most of area of China all can obtain utilizing.

For achieving the above object, the technical solution of the utility model comprises: jet pipe, generator set, wind direction rudder and link etc.The fluid that utilizes same traffic under the normality is during by different cross section, and the fluid properties that flow velocity and sectional area are inversely proportional to is designed to jet pipe horn-like.Dwindle gradually from nozzle hole to aditus laryngis, the nozzle hole area is greater than the aditus laryngis sectional area, and aditus laryngis can effectively reduce the loss of airflow kinetic energy to this section increaser of jet pipe tail.Flow velocity increases when flowing into the low velocity wind process aditus laryngis of nozzle hole, is installed in generator fan blade quick rotation under the driving of this wind-force of aditus laryngis portion, thereby reaches the purpose of utilizing breeze wind.The utility model can generate electricity separately with a jet pipe, also many jet pipes that wind-driven generator is housed can be used in combination, to improve generate output.

The utlity model has that volume is little, in light weight, simple in structure, low cost of manufacture, using effect are good, be suitable for advantages such as the region is wide, use for the wind energy in few wind area and opened up new way.

Embodiment

As Fig. 1, jet pipe is made up of nozzle hole 1, aditus laryngis 2, jet pipe tail 3; Nozzle hole 1 to aditus laryngis dwindles for 2 sections gradually, larynx 2 to jet pipe tail has expansion again for 3 sections slightly, be the sectional area of the sectional area of nozzle hole 1 much larger than aditus laryngis 2, the sectional area of jet pipe tail 3 is a bit larger tham the sectional area of aditus laryngis 2, and the longitudinal section of jet pipe tube wall is circular-arc or the semi-parabolic shape.

Generator set is made up of fan blade 4 and generator 5; Fan blade 4 is installed on the axle of generator 5, and generator 5 is installed in the jet pipe by the supporting element on the fixed tube 7, and the axis of generator 5 overlaps with nozzle axis, and the radial position that makes fan blade 4 is between aditus laryngis 2 and jet pipe tail 3.

The wind direction rudder is made up of rudder stock 8 and rudder tail 9; Rudder tail 9 is connected on the rudder stock 8, and rudder tail surface and rudder stock vertical center line are at grade.

Link is made up of locking hoop 6, fixed tube 7, connecting tube 10, steering bearing 11 and support 12.

As Fig. 2, Fig. 4, with locking hoop 6 jet pipe is fixed on the fixed tube 7, fixed tube 7 is connected with connecting tube 10, is fixed on the support 12 by steering bearing 11 again, and bearing 11 can rotate on horizontal plane by the box haul rudder flexibly.The rudder stock 8 of wind direction rudder is fixed on certain suitable connecting tube 10, and makes the vertical center line of rudder stock 8 parallel with nozzle axis, the plane of rudder tail 9 is perpendicular to the ground.
