Description
Technical field
The present invention relates to wind power utilization device, particularly a kind of blade can receive the tower wind energy engine of folded horizontal axis.
Background technique
The tower blade wind energy engine of horizontal axis traditional is at present by blade, wind tower, and main frame forms, and its structure supports main frame by wind tower, and blade is placed in main frame front.This topology layout designs for the environmental conditions of land, and as met super-strong wind-power, wind energy engine is generally avoid air blast damage equipment to ensure safety with lock shaft halt mode.Also the design had adopts two-part combined blade; as Chinese patent: 201210526207.3 " the two-part oblique fold impeller assemblys for large-scale wind driven generator "; its blade comprises primary blades and folding blade, when running into strong wind and disaster caused by a windstorm, can enter the complete folding position of safety protection.But open because its blade is still in, state windward, even if blade wind-receiving face reduces, but still there is the risk damaged by air blast in equipment.
On the other hand, the tower blade wind energy engine of traditional horizontal axis is unsuitable for installing and aboard ship uses, the particularly boats and ships of medium and small tonnage.Wind energy engine aboard ship uses can be very different from the situation of land; because ship floats in water; hull cannot be fixed; when meeting high wind, as the measure of shutting down with lock shaft, although fan blade is locked; but still be in state stressed windward; can cause the more unstable of hull, although so wind energy on the sea is sufficient, also difficulty is shown in has this type of wind energy engine to equip fishing boat.And traditional sail ship sail capturing wind energy, meet high wind reefing mode and ensure safe.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
The object of the present invention is to provide a kind of blade to receive stacked wind energy engine, to solve in prior art, to evade high wind ability weak, easily damaged by high wind, leaf folding is complicated, trouble, and folding wind sheltering effect is undesirable, the technical problem of environmental suitability difference etc.
The object of the invention is to be achieved through the following technical solutions:
A kind of blade receives stacked wind energy engine, include column, wind energy main frame, at least one pair of blade, horizontal rotating shaft and break, clutch, it is characterized in that: a pair described blade is divided into stator blade and moving vane, stator blade and stator blade seat are connected, stator blade cover for seat is loaded on horizontal rotating shaft, moving vane and moving vane seat are connected, moving vane seat is provided with bayonet socket, and moving vane seat is set on stator blade seat by bayonet socket again, makes moving vane be in same plane with stator blade and relatively to launch with 180 °; The front end of horizontal rotating shaft is provided with screw mandrel, is provided with transmission nut in moving vane seat end-face central hole, and screw mandrel and transmission nut form transmission and coordinate; Moving vane seat front end is also provided with control motor, and on transmission nut, concentric is fixed with gear, and gear engages with the output gear controlling motor, by controlling the clockwise and anticlockwise of motor, moving vane seat can be driven to exit along screw mandrel or overlap and putting into stator blade seat.
Further, obtain secondary for making residue wind energy and utilize, improve wind energy utilization efficiency, described blade is totally two right, and its blade incidence is installed with angle Symmetrical by same direction windward, and is connected in series by coaxial reverse.
For lowering the center of gravity, increase stability, also installation and maintenance are convenient to, described wind energy main frame is loaded on column bottom, vertical pivot is provided with in column, vertical pivot lower end is connected with wind energy main frame power, and vertical pivot upper end is then connected by the splined shaft of bevel gear, umbrella gear and level, clutch, break and horizontal rotating shaft power.
Follow the tracks of wind direction for ease of selecting, described column bottom installs rotating disk, and rotating disk can drive column to do level 360 ° rotation.
Particularly, described column top is fixedly mounted with transverse pipe beam, overall in T shape, divide in Guan Liang and be each side symmetrically installed with a horizontal rotating shaft and a splined shaft, one end of splined shaft is fixedly mounted with umbrella gear, the other end is fitted with key pin clutch, break exterior edge face have key pin hole can with key pin clutch engagement, break is installed in the rear end of horizontal rotating shaft.
Described stator blade and stator blade seat Flange joint, moving vane and moving vane seat are also Flange joint, on moving vane seat, the opposite side of self neck flange corresponding has bayonet socket, this bayonet socket slidably engagement sleeves feed into or exits the neck flange of stator blade seat, and there is stiffening rib at bayonet socket edge; When receiving folded blade, control motor-driven gear, transmission nut, drive moving vane seat to exit stator blade seat along screw mandrel, after the bayonet socket on moving vane seat exits the neck flange of stator blade seat completely, stator blade and moving vane two blades can be received and be stacked as 0 °, the locking of vertical the earth's core.
Described column cross section is the wing body of streamline.
The present invention has the following advantages: 1, have blade and receive folded, folding function, blade is received poststack and can be on same straight line with column, and wind-receiving face greatly reduces.Can high wind be evaded in actual applications, be adapted at vessel, comprise on fishing boat and using, widen wind energy engine application.2, optionally utilize wind energy, can at the sea of many high wind, seashore use.This is embodied in, and under the condition of usual wind-force, two groups, available front and back blade co-operation, but when running into high wind weather, can select to realize working independently with wherein one group of blade, reduce unit load, add applicability.3, blade receives overlapping folding function for ship, and both can evade high wind, Rotary cloumn also can be used as crane and uses, and can keep original mast function on ship.4, wind energy main frame is placed in below column, can lower the center of gravity, improve stability, more makes a lot of installation and maintenance work need not high-lift operation, only carries out under column, very convenient.5, two groups, front and back blade contrarotation, front vane residue wind energy obtains secondary and utilizes, and improves wind energy utilization efficiency.6, streamlined column reduces gas-flow resistance, and little on rear blade impact, column bending strength improves.
