Abstract

The utility model relates to a rotating air-flow electric generator used for wind power generation. The generator can be started when wind speed reaches to 0.5-1.5 m / s, and the generator can be used for normal power generation when wind speed reaches to 2-3 m / s. Due to the utilization of air-flow movement in an air duct, wind speed at an air outlet has little variation when the wind speed at an air inlet changes, and thus output power can be controlled. The rotating air-flow electric generator has convenient installation and transportation can be transported entirely and moved again after installation.

Description

Rotating air-flow electric generator

The utility model relates to a kind of wind-driven generator, especially a kind of horizontal air flow electric generator of being convenient to move.

As everyone knows, the electric energy that people are nowadays used comes from waterpower or thermal power generation.Also once the someone invents with wind-force and generates electricity.The windmill type wind-driven generator is exactly a kind of of wind-power electricity generation.The appearance of this generator contributes for the new energy is provided, but its development is restricted.Reason can only be utilized positive wind energy in: windmill type wind-driven generator again; Its starting force needs 3 grades of (3m/s) above wind speed apart from big, and work wind speed needs 4～6 grades of (4m/s) above wind speed; Output power is wayward; Must consider the rated wind velocity problem during installation; In a single day transportation, installation inconvenience particularly install, and then inconvenience is moved once more.

The purpose of this utility model is: make full use of secondary energy--wind-force; for both protecting environment; can obtain electric power again and proposed a kind of starting wind velocity low (0.5～1.5m/s), work wind speed is low by (2～3m/s); do not utilize front wind merely, and the wind-driven generator of the swirling eddy formula that can control of output power.

Swirling eddy formula generator has adopted horizontal type structure, and its formation comprises: dividing plate, rotor, upper and lower covers, generator and speedup box etc., the runner of wind is made up of loam cake (5), lower cover (7), dividing plate (1).Dividing plate is logarithmic spiral shape, and several dividing plates are installed between the upper and lower covers equably.The upper and lower covers ingress is to constitute hyperboloid by hyperbola rotation, and the outlet port is conical surface, and connection is smoothly filtered on the two sides, in the geometrical center of curved surface one major axis (12) is installed, and rotor (2) is equipped with in the major axis upper end, and umbrella gear (9) is equipped with in the lower end.Rotor is leg-of-mutton, and following point is gone up wide, and its blade is logarithmic spiral shape, left-handed installation during installation, and this rotor top is provided with a flat cover (3).

Accompanying drawing 1 is swirling eddy formula generator Structure figure, and 1 is dividing plate among the figure, the 2nd, and rotor, the 3rd, flat cover, the 4th, support, the 5th, loam cake, the 6th, speedup box, the 7th, lower cover, the 8th, storage battery, the 9th, umbrella gear, the 12nd, major axis.

Accompanying drawing 2 is that B-B is to figure.

Accompanying drawing 3 be A-A to figure, 6 is speedup boxes among the figure, the 8th, storage battery, the 10th, generator, the 11st, belt.

The utility model is made the following example: wooden structure, upper and lower covers diameter 500mm, high 250mm, exhaust outlet diameter 110mm, entry port section 120 * 105mm ², the dividing plate in the middle of the upper and lower covers is 12, is cut into iron plate, imbeds between the upper and lower covers, forms the air channel.Flat cover diameter 160mm is connected as a single entity with the cone rotor, forms the low pressure area of an air-flow at the central outlet end of loam cake, but makes all air intakes of four sides.Diameter 120mm at the bottom of the cone, high 80mm embeds 3 rotor blades equably along conical surface logarithmic spiral, and it is wide to be 30mm.

The utility model is achieved in that the air-stream type generator is horizontal, and lower cover is a base.Distinguished and admirable realization is to form runner by loam cake (5), lower cover (7), dividing plate (1), and several dividing plates are logarithmic spiral shape and are installed between the upper and lower covers equably.In the geometrical center of generator, a major axis (12) is installed, there is rotor (2) major axis upper end, and umbrella gear (9) is equipped with in the lower end, joins by speedup box (6) and belt pulley and generator (10).After wind enters runner from direction as shown, because the effect of dextrorotation logarithmic spiral shape dividing plate, make wind that the front enters in outlet end generation right rotation, form the right rotation air-flow thus in the upper and lower covers center portion.The rotation of this strand air-flow is risen and is conical surface ejection by outlet, drives the rotor rotation on the major axis, drive generator (10) generating by umbrella gear (9), speedup box (6), and the electrical power storage that will obtain thus is in storage battery (8).The rotor (2) that is installed on the major axis (12) is leg-of-mutton, and following point is gone up wide, and its blade also is a logarithmic spiral shape, but this blade is left-handed installation.Therefore the air-flow of dextrorotation enters among the left-handed runner of rotor, thereby drives the rotor high-speed rotation.The pressure distribution outside of the dextrorotation air-flow of outlet end is a malleation, and the inboard is a negative pressure.For preventing that top air-flow from entering the rotor adverse current, above rotor, add a flat cover (3).Like this, air-flow can only from bottom to top rotate, rise and promote rotor rotation, because rotor and air-flow all rotate, form the low pressure area of an air-flow at the central outlet end of loam cake, except the wind in front can flow into along row ground, the air of both sides and back thereof went out and can suck thus, form the state that " on four sides " the wind comes from, also formed the bigger swirling eddy of one power simultaneously.

The utility model and existing windmill type generator ratio, advantage is more. Can utilize positive wind energy, can utilize the wind energy of both sides and back again, thereby improve efficient; Can not consider the problem of rated wind velocity; Starting wind velocity is low, and the wind speed of 0.5～1.5m/s can start, and work wind speed is low, during the wind speed of 2～3m/s, but just normal power generation; Because the effect of air motion mechanism in the air channel, so that the air port wind speed is when changing, the wind speed of air outlet changes not quite, and so that power output controlled; Contrast traditional propeller generator, when identical power stage, the Master Cost of this device is wanted much less, has reduced cost, and installation and transportation are convenient, but the complete machine transportation is again mobile also more convenient after the installation.
