Abstract

The utility model relates to an open and retraction type sail turbine which belongs to a wind power motor with a rotary axis perpendicular to the wind direction. The wind receiving components of the utility model, namely blades, are driven through a pinion gear and a circular arc-shaped chain which are arranged on a rotary component for retraction and open, so that the non-power resistance is overcome, a large wind pressure difference is formed, and a strong motive power is generated.

Description

Open and contraction type sail turbine

The utility model belongs to the wind motor that has with the rectangular spin axis of wind direction, is a kind of receipts formula sail turbine of opening concretely.

Chinese patent 87208825 discloses a kind of " sail-turning type fluid turbine ".It with jibe make can unidirectional folding " door " formula sail, and this " door " formula sail is installed on the sail rotating frame blade that constitutes the fluid turbine, when fluid passed through the sail turbine, a part " door " formula sail was closed on sail rotating frame, and another part " door " formula sail is opened.This turbine mainly produces moment of torsion by the opening and closing of " door " formula sail and makes the turbine rotation in rotating shaft.The design people provides a kind of formula sail turbine that blocks in Chinese patent application 91201972.7, it adopts jibe, and the windbreak that some sail is formed by windscreen blocks to reduce reverse moment of torsion.

The purpose of this utility model provides a kind of sail turbine, and its wind-engaging part is a blade, thereby driving can pack up and open by the small gear of design on rotating member and chain overcomes non-power resistance and cause very big blast official post sail turbine rotation.

The design is characterised in that an end that is installed in the little axle 9 on the bearing 12 that revolves a main shaft 14 is equipped with small gear 6, the other end is equipped with large pulley 7, the gear teeth of small gear 6 be contained in perpendicular to the garden arc-shaped chain on the level board 15 of supporting frame and horizontal positioned 16 engagement, main shaft bearing 12 drives small gear 6 when 16 rotations of garden arc-shaped chain, because the reaction force of interlock drives large pulley 7 and truckle 8, and the canvas 3 on the blade can be opened and pack up.

The accompanying drawing 1 that the utility model provides has illustrated the design's a specific embodiment.

1 is the sail mast in the accompanying drawing 1, the 2nd, and sliding sleeve, the 3rd, canvas, the 4th, horizontal rope, the 5th, perpendicular rope, the 6th, small gear, the 7th, large pulley, the 8th, truckle, the 9th, little axle, the 10th, little axle bearing, the 11st, movable rope, the 12nd, main shaft bearing, the 13rd, supporting frame, the 14th, main shaft, the 15th, level board, the 16th, chain.

Detailed says, the utility model is provided with a cover small gear 6, perpendicular to the vertical plane of forming by supporting frame 13 and main shaft 14 and be placed on supporting frame 13 tops level board 15 is arranged, each fixes the chain 16 of one section garden arc its two ends, the position of chain at small gear along on the garden shape track of main axis rotation, so when main bearing 12 forwards certain position to, small gear 6 just is meshed with chain 16, the Position Design of chain 16 at level board 15 two ends becomes the little tooth engagement in upper end of the chain and the small gear 6 of an end, and the little tooth interlock in the chain of the other end and lower end, when main bearing 12 rotations, small gear can be that axle center forward or

reverse drive pulley

7 and 8 makes canvas open or pack up with little axle 10 just like this.

Garden arc-shaped chain on the level board 15 can be contained in the top of plate, also can be placed on the bottom of plate, and canvas is opened above main shaft 14 in order to the wind with top when being contained in top, and when being contained in the bottom, canvas is opened below main shaft, thereby utilizes the wind of bottom.

When chain 16 is contained in level board 15 tops, thereby the last tooth of the small gear on the rotating blades 6 or lower tooth at first roll small gear with the chain engages of level board front end and open canvas gradually from the bottom up, when small gear rolling on the chain finish after, canvas is also just opened fully, and canvas 3 just can be accepted the wind-force promotion turbine continuation rotation on top like this.When forwarding the other end to, blade accepts wind-force when less or practically negligible, small gear 6 again with the chain engages of level board 15 the other ends, thereby canvas is accepted, when it forwarded the main shaft below to, wind-exposuring area will be quite little like this, and resistance also reduces greatly, when previous blade is about to pack up or harvested canvas, (this can realize by the position of regulating chain), a back blade works on again, repeats the program of front.Because the design has accomplished the blade canvas of turbine main shaft top and has opened, and the canvas of below is packed up, the wind-exposuring area of top blade just substantially exceeds following wind-exposuring area like this, causes a very big leeway, just can make the turbine rotation by this pressure reduction.This is the design's turbine work principle just.

For realize canvas to open and pack up by its blade of design of the present utility model be to constitute like this, one end of canvas 3 is fixed on the horizontal rope 4, the other end is fixed on the sliding sleeve 2, and sliding sleeve is enclosed within on sail mast 1 or the perpendicular rope 5, sliding sleeve 2 is fixed on the movable rope 11, and the movable rope two ends are enclosed within respectively on truckle 8 and the large pulley 7, truckle is fixed on the top of sail mast 1, large pulley 7 and small gear 6 are separately fixed at the top of little axle 9, little bearing 10 is fixed on the main bearing 12, when small gear 6 rotates, will drive large pulley 7 and rotate, large pulley 7 then drives movable rope 11 and moves up and down.Movable rope 11 moves one on the other around pulley, sliding sleeve with on sliding or glide, Gu and canvas can be opened and pack up.

Data show, the wind speed of 300 meters eminences approximately is 2.2 times of ground wind speed apart from ground.Therefore this sail turbine when its blade do huge more the time, should utilize the wind-force above the main shaft more, promptly the top that chain 16 is placed on level board 15 is preferable selection.

The design's sail turbine should use flexible canvas so that open and pack up.For the various devices that utilize wind-force, the bearing capacity of flexible canvas will be considerably beyond other rigid material, this is confirmed on sailing boat, for preventing the excessive strength deficiency of canvas, specially install perpendicular rope additional, strengthening its intensity, the two ends of perpendicular rope all are fixed on up and down on two horizontal ropes, and quantity can arbitrarily increase or reduce.In addition the quantity of the design's blade can be three as shown in Figure 1, also can be four or other number.

The characteristics of the design's sail turbine maximum are as long as the sail mast is taked some strengthening measures, reinforce as the sail mast on each limit being linked to each other in twos with cable wire, blade just can be done quite tall and bigly, promptly this turbine is suitable for maximizing or large, and the upper blade after maximizing just can be utilized than the strong a lot of aerial wind of surface wind, so it can have sizable power, the most general turbo machine of use far away can not be by comparison now.

Variation that can not box haul owing to the leaf position of this machine changes, so its construction position must be selected in the more stable place of wind direction, as seashore or air port, makes it utilize more wind-force as best one can over against wind direction, sends bigger power.
