Abstract
Louvre type vertical shaft resistance type windmill belongs to wind power generation field.Principle is that symmetry has installed four louvre type flabellums on a vertical shaft.Each flabellum is mounted to the dynamic plate of perpendicular row by multiple interval and determines plate and form.When static wind energy conversion system runs into the wind of some strength, always have a flabellum to be in upwind position, its top is moved plate and is blown, and drives dynamic plate to realize self-starting.In rotation process, the first moving vane that flabellum outer side surface is installed in position stirs dynamic plate by helical teeth roller box, produces moment of rotation.When not producing moment of rotation, dynamic plate drops to and determines plate parallel position, makes rotational resistance minimum.Resistance fan moment of rotation is directly proportional to wind-exposuring area, and rotational resistance is directly proportional to wind resistance area.Dynamic plate structure makes wind-exposuring area and wind resistance area can reach hundreds of than one, which greatly improves the efficiency of shaft resistance type windmill.Its manufacture cost of structures shape is lower, and area increased just can improve power, and this makes wind-power electricity generation enter the high-power low cost epoch.
Description
One technical field
The invention belongs to the vertical-axis resistance wind-driven generator in wind power generation field.
Two background techniquies
1 typical resistance type wind-driven generator
It is that when static, its ratio is about 1/2 because there is different resistance coefficients on its blade two sides that typical case's shaft resistance type windmill produces torque, and its blade is being constant with the area of resistance positions windward.This speed that typical shaft resistance type windmill is produced and moment all very little, efficiency is very low.
The wind collection device (patent No. ZL201220026570.4) of 2 one kinds of vertical axis wind power generations
" a kind of wind collection device of vertical axis wind power generation " has some shortcomings below:

(2) rotating shaft of the moving vane of " a kind of wind collection device of vertical axis wind power generation " is at the edge of blade, its be close to when horizontal position below stator blade, thus in the weather of wind and snow or dust storm, easily between moving vane and stator blade, cause wind energy conversion system cisco unity malfunction stored in snow or sand or accelerate the damage of wind energy conversion system;
(3) " a kind of wind collection device of vertical axis wind power generation " does not have self-starting to arrange;
(4) " a kind of wind collection device of vertical axis wind power generation " does not slow down or shuts down control setting.
Three summary of the invention
1 adopts dynamic plate structure, and make the wind-exposuring area of the flabellum of louvre type vertical shaft resistance type windmill when symmetrical position and drag area produce significant change, its ratio can reach hundreds of than one.Therefore, the moment of rotation of wind energy conversion system and maximum speed all much higher than typical shaft resistance type windmill.Concrete enforcement be four louvre types flabellum framework (4) in have interval to install, become multiple dynamic plate (3) He Dingban (2) composition (see Fig. 1) of perpendicular row.Determine plate plate face parallel to the ground, dynamic plate has axle can rotate (see Fig. 4).First moving vane (7) produces moment of rotation and passes to dynamic plate through helical teeth roller box (5), first dynamic pivoted arm (9) etc. windward time, kick up windward in the wide side of dynamic plate and determine plate with upper and lower or the upper and lower inner side surface of flabellum framework contacts simultaneously, form choke and pass through and produce the effect of maximum rotation moment; Move plate during in the narrow side of dynamic plate windward to fall and contact with dynamic plate supporting plate (13), simultaneously parallel with determining plate position, by flabellum framework, resistance is minimum most possibly to make air.
2 adopt first moving vane by helical teeth roller box, the structure that dynamic plate controls to be substantially reduced to the wind resistance area of control system, compare, significantly reduce the wind resistance area of control system with " a kind of wind collection device of vertical axis wind power generation ".
Specific embodiments is that first moving vane (7) is hinged on blade turning handle (15), and blade turning handle is contained on the gear shaft that stretches out at helical teeth roller box (5) top, and blade has axle can rotate on blade turning handle.When arriving upwind position, originally close to level, tilted-putted first moving vane, moved rotation on blade turning handle by wind and erect, produce large wind resistance area (see Fig. 5), blade turning handle is rotated, and by helical teeth roller box, first dynamic pivoted arm, turning handle collaborates plate, dynamic plate turning handle makes plate kick up (see Fig. 1).And forward to wind less than angle time, first moving vane falls, and wind resistance area becomes again very little.
The rotating shaft positions of 3 dynamic plates have made change, compare and both increase area when the dynamic plate radius of gyration is constant, improve efficiency with " a kind of wind collection device of vertical axis wind power generation ", the dead angle and be provided with the function of wind resistance snow and anti-blown sand of not drying again.
Specific embodiments is that the rotating shaft of plate is not or not most edge (see Fig. 4), and slightly partially opens the position of some at center line.This makes, when dynamic plate is parallel with determining plate, to there is comparatively wide arc gap therebetween, and when maximum choke position, wind can follower plate and the gap of determine between plate pass through, and avenging, or sand etc. all blows off.When the dynamic plate wide side radius of gyration is constant, slewing area (adding the area of narrow side) has a larger increase again, thus improves efficiency.
4 adopt top to move the structure of plate by self-starting bar control keep plate, make wind energy conversion system have self-starting function.
Concrete enforcement is when wind energy conversion system of the present invention runs into the wind of some strength in state of rest, and the top being in larger wind-exposuring area is moved plate (see Fig. 1) and is blown up, and drives dynamic plate to kick up by self-starting bar and realize self-starting.
5 are provided with dynamic plate controller, can regulate the amplitude that raises up of dynamic plate as required, to control generated output and shutdown.
Concrete enforcement (see Fig. 3) is under plate is moved at top, install dynamic plate amplitude controller, dynamic plate amplitude controller is driven by micromachine, and micromachine can control its action by computer or external beepbox, plate and the maximum upper limit of kicking up of dynamic plate are moved in restriction top.When the push rod of dynamic plate amplitude controller is in extreme lower position, the movement range of dynamic plate is maximum, and the push rod of dynamic plate amplitude controller is when extreme higher position; dynamic plate is limited in horizontal position; then wind energy conversion system wind-exposuring area is identical with wind resistance area, and moment of rotation almost disappears, and can easily realize shutting down.When dynamic amplitude controller push rod the highest and minimum between certain position time, dynamic plate and top are moved plate and are then opened corresponding angle, realize the object reducing rotational velocity.

Five embodiments
See Fig. 1, Fig. 2 and Fig. 3, when static wind energy conversion system runs into the wind of some strength, a flabellum framework (4) is always had to be in the maximum position of wind-exposuring area, its top is moved plate (8) and bottom and is moved plate (10) and blown, and top is moved plate (8) by self-starting bar (1) and is driven dynamic plate (3) to raise up, dynamic plate (3) with determine plate (2) up and down and contact and form maximum wind resistance area, this flabellum framework (4) receives the thrust of wind, and wind energy conversion system realizes self-starting.
See 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) be arranged on outside framework is first erected by wind, produce larger wind resistance area, thus blown and turned an angle, its moment of rotation produced becomes vertical surface moment of rotation by helical teeth roller box (6), make first to move pivoted arm (11) upwards to rotate and stir first dynamic connecting rod (5) upwards action, and first dynamic connecting rod (5) drives first dynamic turning handle (9) to drive dynamic plate (3) upwards to kick up to receive the thrust of wind, wind energy conversion system is rotated further.This framework is rotated further, and first moving vane (7) first loses the blowing force of wind and gets back to original position.But dynamic 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 angle, at the heel framework has forwarded acting angle to, and the action repeating framework before it continues acting makes wind energy conversion system rotate continuously.
Framework (4) is when producing acting angle, and dynamic plate (3) drops on Horizontal limiting plate (12) at the force action of gravity and wind and thus makes wind resistance area minimum.
See Fig. 1 and Fig. 4, the rotating shaft of dynamic plate (3) neither at most edge also not at position of center line, make dynamic plate when horizontal position with below plate (2) of determining also have larger space and do not exist and deposit thing dead angle.When framework is when non-acting area rotation is to maximum resistance wind speed, dynamic plate (3) He Dingban (2) is " wind speed+rotating speed " with the relative velocity of wind, reach maximum value, so at utmost the snow moved above plate (3) He Dingban (2) and sand are blown clean, reach self cleaning effect.
See Fig. 3, when wind-force is excessive, keep plate amplitude controller (12) upwards action can be controlled, make top move plate (8), and upwards to be kicked up maximum amplitude by self-starting bar control keep plate.Thus realize power control and shut down.
Six shortcoming of the present invention and advantages
The rotating speed of 1 wind energy conversion system of the present invention can reach the several times of typical shaft resistance type windmill, but also belongs to low speed WECS, and its maximum (top) speed is still lower than wind speed.And working speed is just lower.
But typical shaft resistance type windmill has good self-starting function, has powerful torque when its low speed is described.Shaft resistance type windmill moment of rotation is directly proportional to wind-exposuring area, and rotational resistance is directly proportional to wind resistance area.Dynamic plate structure makes wind-exposuring area and wind resistance area can reach hundreds of than one, and this makes the torque of louvre type vertical shaft resistance type windmill of the present invention more much bigger than typical shaft resistance type windmill again.And the feature of vertical axis windmill of the present invention makes speedup and power generating equipment can be arranged on fixing device, powerful torque can be changed into efficient generating by reliable speedup like this.
By sheet material manufacture, 2 main structures of the present invention determine that manufacture cost of the present invention is lower, area increased just can improve power, and this makes wind-power electricity generation enter the high-power low cost epoch.
3 the present invention have efficient self-starting performance and make it possible to utilize lower wind speed work.
4 the present invention are simple and reliable control system makes resistance type wind-power electricity generation practical safely.
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.The gear shaft that the end face of helical teeth roller box stretches out is filled with the blade turning handle and first moving vane (see Fig. 5) that can horizontally rotate.The gear shaft that helical teeth roller box outer side surface stretches out is filled with first dynamic pivoted arm.Move in rotating shaft that plate stretches out at framework outer side surface and dynamic plate turning handle is installed, and collaborate bar by turning handle between dynamic plate turning handle and be hinged together, make it synchronous axial system (see Fig. 1).When flabellum arrives special position, first moving vane is erected the moment of rotation of generation by wind, and stir dynamic plate by helical teeth roller box and kick up and determine plate and form maximum wind resistance area, flabellum framework receives the thrust of wind and produces moment of rotation.When dynamic plate is in the thrust position that can not accept wind, horizontal position can be fallen and form maximum ventilation area.Making wind when promoting frame member, forming maximum thrust; And it is minimum in the rotational resistance of the region inner gimbal that other wind do not do work.
