Abstract

Provided is a shutter type vertical axial resistance type wind turbine and a wind collecting device thereof. Four shutter type blades are symmetrically installed on a vertical shaft, and each of the blades is formed by multiple moving plates and fixed plates, which are installed in one vertical line at an interval. When the static wind turbine encounters wind of certain intensity, at least one of the blades is in a windward position, and a top moving plate of the blade is blown to drive a corresponding moving plate to automatically start. During rotation, first moving blades installed on the side faces of the blades poke moving plates via helical gear boxes in proper positions to generate driving torque. When driving torque is not generated, the moving plates drop to positions parallel to corresponding fixed plates to minimize the driving resistance. The driving torque of the wind turbine is in direct proportion to a windward area, and the driving resistance is in direct proportion to the windward area. Via the moving plates, the ratio of the windward area to a wind resisting area can achieve hundreds to one, so efficiency of the wind turbine is greatly improved. Therefore, manufacturing costs of the wind turbine are lower, and by increasing areas, power can be improved, so in future, power is larger and costs are low for wind power generation.

Embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, when static wind energy conversion system runs into the wind of some strength, always there is the position of a flabellum framework 4 in wind-exposuring area maximum, the moving plate 10 of the moving plate 8 in its top and bottom is blown, and the moving plate 8 in top drives moving plate 3 to raise up by self-starting bar 1, moving plate 3 contacts the maximum choke area of formation with determining up and down plate 2, and this flabellum framework 4 receives the thrust of wind, and wind energy conversion system is realized self-starting.

Referring to Fig. 5, Fig. 6, Fig. 7 and Fig. 8, when a certain flabellum framework 4 in rotation process turns to special position, the first moving vane 7 that is arranged on framework outside is first erected by wind, produce larger choke area, thereby turned an angle by being blown, the moment of rotation of its generation becomes vertical surface moment of rotation by helical teeth roller box (6), making first to move pivoted arm 11 upwards rotates and stirs first moving connecting rod 5 and upwards move, and first moving connecting rod 5 drives first moving turning handle 9 to drive moving plate 3 upwards to kick up to receive the thrust of wind, wind energy conversion system is further rotated.This framework is rotated further, and first moving vane 7 first loses the blowing power of wind and gets back to original position.But moving plate 3 still can receive the thrust of wind in several angle, keeps maximum wind-exposuring area.

When this flabellum framework 4 does not also thoroughly produce acting when angle, at the heel framework has forwarded acting angle to, repeats before it action of framework and continues acting wind energy conversion system is rotated continuously.

Described flabellum framework 4 is producing acting when angle, and moving plate 3 drops on Horizontal limiting plate 12 thereby makes choke area minimum at the force action of gravity and wind.

Referring to Fig. 1 and Fig. 4, the rotating shaft of moving plate 3 neither at edge also not at position of center line, make moving plate in the time of horizontal position with below the plate 2 of determining also have larger space and do not have thing dead angle.When framework is at non-acting area rotation during to maximum resistance wind speed, moving plate 3 is " wind speed+rotating speed " with determining plate 2 with the relative velocity of wind, reach maximum value, so at utmost blow clean moving plate (3) He Dingban (2) snow and sand above, reach self cleaning effect.

Referring to Fig. 3, in the time that wind-force is excessive, can controls keep plate amplitude controller 12 and upwards move, the moving plate 8 in top is fallen, and by the self-starting bar control keep plate maximum amplitude of upwards kicking up.Thereby realize power control and shutdown.

Flabellum framework outer side surface is installed with helical teeth roller box, has two helical gears in helical teeth roller box, a gear shaft vertical ground, the parallel ground of gear shaft.On the gear shaft that the end face of helical teeth roller box stretches out, filling blade turning handle and the first moving vane (seeing Fig. 5) that can horizontally rotate.On the gear shaft that helical teeth roller box outer side surface stretches out, filling first moving pivoted arm.In the rotating shaft of stretching out at the moving plate of framework outer side surface, moving plate turning handle is installed, is hinged together and collaborate bar by turning handle between moving plate turning handle, make it synchronous rotation (seeing Fig. 1).Flabellum arrives when special position, and first moving vane is erected the moment of rotation of generation by wind, stirs moving plate kick up and form maximum choke area with determining plate by helical teeth roller box, and flabellum framework receives the thrust of wind and the moment that rotates.When moving plate is in the time can not accepting the thrust position of wind, can fall horizontal position and form maximum ventilation area.Make wind in the time promoting framework rotation, form maximum thrust; And the rotational resistance minimum of the region inner gimbal not doing work at other wind.

As from the foregoing, the utlity model has following feature:

1. adopt moving plate structure, wind-exposuring area and the drag area of the flabellum that makes louvre type vertical shaft resistance type windmill in the time of symmetrical position produces significant change, and its ratio can reach hundreds of than one.Therefore, the moment of rotation of wind energy conversion system and maximum speed are all much higher than typical shaft resistance type windmill.Concrete, in the flabellum framework 4 of four louvre types, all install, become the multiple moving plate 3 of perpendicular row and determine plate 2 by interval to form (seeing Fig. 1).Determine plate plate face parallel to the ground, moving plate has axle can rotate (seeing Fig. 4).First moving vane 7 rotates moment through helical teeth roller box 5, first moving pivoted arm 9 etc. passes to moving plate windward time, kick up windward and determine plate or the upper and lower inner side surface of flabellum framework contacts with upper and lower simultaneously in the moving wide side of plate, form choke by producing the effect of maximum rotation moment; The narrow side of moving plate windward time moving plate fall with moving plate supporting plate 13 and contact, simultaneously parallel with determining plate position, makes air most possibly by flabellum framework and resistance minimum.

2. the structure that adopts first moving vane by helical teeth roller box, moving plate to be controlled has reduced the choke area of control system greatly, compares with " a kind of wind collection device of vertical axis wind power generation ", has significantly reduced the choke area of control system.

Concrete, first moving vane 7 is hinged on blade turning handle 15, and blade turning handle is contained on the gear shaft stretching out at helical teeth roller box 5 tops, and blade has axle on blade turning handle, to rotate.In the time arriving upwind position, originally approach level, tilted-putted first moving vane, moved rotation on blade turning handle by wind and erect, produce large choke area (seeing Fig. 5), blade turning handle is rotated, by helical teeth roller box, first moving pivoted arm, turning handle collaborate plate, moving plate turning handle and make plate kick up (seeing Fig. 1).And forward to wind less than angle time, first moving vane falls, choke area becomes again very little.

3. the rotating shaft position of moving plate has been made change, both compared and increased area in the situation that the moving plate radius of gyration is constant with " a kind of wind collection device of vertical axis wind power generation ", improved efficiency, does not dry dead angle again and has had that wind resistance is avenged and the function of anti-blown sand.

Concrete, the rotating shaft of moving plate is not or not edge (seeing Fig. 4), and the position of slightly partially opening some at center line.This make when moving plate with determine plate when parallel, between the two, there is larger gap, in the time of maximum choke position, wind can follower plate and the gap of determine between plate pass through, avenging, or sand etc. all blows off.In the situation that the wide side radius of gyration of moving plate is constant, slewing area (having increased the area of narrow side) has again a larger increase, thereby has improved efficiency.

4. adopt the moving plate in top by the structure of self-starting bar control keep plate, make wind energy conversion system there is self-starting function.

Concrete, when described wind energy conversion system is in the time that state of rest runs into the wind of some strength, the moving plate (seeing Fig. 1) in top in larger wind-exposuring area is blown up, and is kicked up and realized self-starting by the moving plate of self-starting bar drive.

5. be provided with moving plate controller, can regulate as required the amplitude that raises up of moving plate, to control generated output and shutdown.

Specifically as shown in Figure 3, moving plate amplitude controller is installed under the moving plate in top, moving plate amplitude controller is driven by micromachine, and micromachine can be by computer or its action of external beepbox control, the moving plate in restriction top and the moving plate maximum upper limit of kicking up.When the push rod of moving plate amplitude controller is during in extreme lower position, the movement range maximum of moving plate, and the push rod of moving plate amplitude controller is in the time of extreme higher position; moving plate is limited in horizontal position; wind energy conversion system wind-exposuring area is identical with choke area, and moment of rotation almost disappears, and can easily realize shutdown.When the push rod of moving amplitude controller the highest and minimum between certain position time, the moving plate in moving plate and top is opened corresponding angle, realization reduces the object of rotational velocity.
