Description

Multilayer is wind power generation stepped

Technical field: the utility model belongs to the wind power generation device structure technical field.

Background technique: wind-power electricity generation is a kind of very environmental protection that produces electric power by nature wind-force, also very economical a kind of production of energy mode, and in petroleum resources today of shortage day by day, the effect of wind-power electricity generation seems more and more important.Existing wind generating unit normally adopts the common fan blade band helical of one deck as wind concentrator at top layer, wind-engaging by fan blade rotates and drives transmission shaft and rotate, by gear-box power transmission is generated electricity to machine shaft then, though this blower fan is because the helix structure of fan blade can absorb wind energy, and has only one deck, the wind energy uptake is little, usually the requirement to wind-force is need reach more than 5 grades, just can make the generator proper functioning, and many places and many time, wind-force is difficult to reach progression like this; The motor of this blower fan is arranged on the wind generator tower body, make wind power generation stepped stability of structure is required very high, construction cost costliness, and very difficulty of lifting is set when installing, use the back maintenance also to be not easy, these have all brought bigger difficulty to wind-power electricity generation.

Summary of the invention: the purpose of this utility model provides a kind of wind-force that can fully absorb for the deficiency that overcomes above-mentioned wind generating unit existence just, also can normal power generation under the gentle breeze situation, generating efficiency is high, and generator is positioned at the body of the tower bottom, very be beneficial to the installation and maintenance of equipment, the multilayer that can greatly reduce wind-force tower building cost is wind power generation stepped.

The purpose of this utility model is achieved by the following technical solution.

The utility model is made up of pillar Tata body, wind concentrator, wind gathering blade, main drive shaft and the motor of a hollow, wherein, be provided with 1～6 layer of wind concentrator altogether to the middle part from the body of the tower top, be arranged on the wind concentrator that first layer is positioned at the top and be fixedly connected on the bearing that is provided with on the cat head, bearing drives the main drive shaft that is positioned at the body of the tower center line and rotates; Main drive shaft is extended in the machine room at the bottom of the pillar Tata by the pillar top of tower by coupling, is connected with a drive clutch in the lower end of main rotary shaft, and this drive clutch is connected with a gearbox, and gearbox is connected with a planet gear driver again; The planetary pinion driver is connected with the transmission shaft of motor; The power-assisted wind concentrator that is arranged on top or middle part adopts chain respectively with main drive shaft and power-assisted wind concentrator rotating shaft to connect by the hole of being opened at the pillar Tata on one's body; The wind gathering blade of the utility model wind concentrator is the vertically rectangular plate structure of band bending of a wind bowl structure or; Or a transverse belt bending and an ascending from the inside to surface rectangular plate structure; Each layer power-assisted wind concentrator that is provided with is arranged in a linear, and each layer power-assisted wind concentrator is that overlapping is arranged; The utility model also is respectively arranged with manhole ladder and outer terraced at the inwall of pillar Tata body and outer wall; And braking device and lightning arrester.

Because wind concentrator is positioned at wind-force body of the tower top and to top multilayer is arranged, whole wind-power electricity generation tower height degree is generally about 10～60 meters, the body of the tower average diameter is about 1～5 meter, be to belong to than relatively large wind generating unit, the utility model changes the blade of wind concentrator into oval bowl-shape blade by original propeller blade, or the blade of the rectangular plate of vertical band bending, or transverse belt bending and ascending from the inside to surface rectangular plate blade, increased the ability of wind gathering, several different blades of caliber size by a connecting rod connection, the fan blade group of being made up of several connecting rods can be with comparatively faint wind again, absorb such as the wind of secondary to three grade and to convert electric energy to, the power-converting of whole wind concentrator, dependence is arranged on a large-scale hermetically sealed bearing at wind-force Tata body top, utilize wind concentrator to order about bearing and rotate, bearing takes main drive shaft again to and rotates; Main drive shaft is extended at the bottom of the tower by cat head always, because axle body is oversize, so will adopt several coupling that several identical axles are linked together; The rotational energy of the power-assisted wind concentrator that top layer is following is transferred to driving force on the main rotary shaft by institute's hole-opening on the corresponding body of the tower by drivign belt or drive chain, thereby has increased the rotational energy of main drive shaft greatly; Too high and damage power generating equipment in order to ensure main drive shaft rotating speed when wind-force is excessive; between main drive shaft and power generating equipment, also be provided with drive clutch; when the main drive shaft rotating speed surpassed rated speed, drive clutch made main drive shaft separate with power generating equipment and plays a protective role.What connect on the main drive shaft behind the drive clutch is the rotating speed that gear-box is used to regulate main drive shaft, latter linked at gear-box is the planetary pinion driver, in order that change the transmission outbound course, the latter linked of planet gear driver is generator, drives motor rotary shaft by planetary rotation and rotates and then realize generator for electricity generation.Whole planetary pinion driver, generator all are arranged in the machine room that builds up at the bottom of the wind-force Tata, in maintenance repair and service equipment process, all just can solve at machine room, very convenient, only when running into wind concentrator generation fault, or coupling is need keep in repair the time, the staff can be by being arranged on wind-force Tata body manhole ladder and outer ladder to the top wind concentrator, top power-assisted wind concentrator, coupling in the tower carries out repair and maintenance, convenient for repair and maintenance, also be provided with a braking device and be used to brake wind concentrator.

Further set forth the utility model content below in conjunction with example and accompanying drawing.
