Embodiment
With embodiment the utility model is described in further detail with reference to the accompanying drawings below:
As shown in Figure 1, present embodiment is a kind of performance of simplifying most of the present utility model, is used for principle of specification.It is by track rope 11, and kite 12 and umbrella 13 are formed.One end of track rope 11 hitches kite 12, and the other end is anchored on the object on ground.Umbrella 13 has many cords 14, and an end of each bar cord ties up to the edge of umbrella, and the other end is fastened on a certain position 15 of track rope 11 together.Umbrella 13 has a center drilling 16.Track rope 11 passes perforate 16, and umbrella 13 just can be fastened on the track rope 11 symmetrically like this.
Will maintain a certain distance between kite 12 and the umbrella 13, purpose is to allow kite lift-off earlier and the influence that is not subjected to umbrella.After the kite lift-off, slowly put the track rope and the most at last umbrella pull on together.Initial umbrella 13 is in free closed state.If wind speed is enough big, umbrella will be opened automatically and be kept stable.If at this moment you can feel strong a lot of pulling force when having only kite with pulling the track rope.
Obviously, the kite 12 of stabilized flight will make track rope 11 and ground that one metastable angle a is arranged.The size of angle is relevant with wind speed, preferably can remain between 15 degree and 80 degree.This angle makes umbrella bear an effective and metastable blast just, thereby keeps stable open mode.
The powerful pulling force that is produced by umbrella is directly proportional with the area of umbrella, and the big more pulling force of area is big more.The maximum feature of this system is to allow a little kite of blowing area drive one than the big several-fold umbrella of its blowing area, thereby produces much bigger system's pulling force.And this umbrella can drive the more large-area umbrella of the next one, produces bigger pulling force.
The shape of umbrella can be various, but preferably circle or polygonal, as Hexagon and Octagon.The cord 14 of umbrella should be no less than three, is polygonal as umbrella, and all should there be a cord each corner so, the cord equal in length on the same umbrella.The material of doing umbrella cover should be pliable and tough and durable, as nylon and acrylic etc.In order to reduce the damage of perforate 16, in the perforate wear-resisting slide block can be installed.
In addition, kite 12 also can be by replacements such as balloon that can be floating aloft or paragliders.Principle is that the rising pulling force of kite or balloon should be greater than the umbrella near kite or balloon, in other words the weight of uppermost umbrella.
System as shown in Figure 2 is by track rope 21, and kite 22 and umbrella 1 and umbrella 2 24 are formed.Umbrella one and umbrella two have been formed a simple umbrella ladder.On the principle, a umbrella ladder can have a lot of umbrellas.
The utility model provides a kind of method and system that effectively utilizes wind energy.This system produces extremely powerful pulling force, can be widely used in generating or promote weight etc.
Shown in Figure 3 is the complete relatively umbrella that can be used to generate electricity a ladder system.It is by guiding kite 32, load umbrella (or claiming balance umbrella) 33, acting umbrella 34, track rope 31 and acting rope 35 compositions.Square frame 36 expression ground force transmission and power generation parts.Ordinary circumstance lower railway rope 31 will be fixed on the object on ground, and acting rope 35 may be in a rotating shaft.Guiding kite 32 also can replace by may float on aerial balloon, and the load umbrella can be more than one.
Fig. 4 is an improved system, and it has acting umbrella 44 and acting umbrella 48 and acting rope 42 and acting rope 43.Two acting umbrella rise and fall times are staggered just can guarantee substantially that system turns round continuously.
As shown in Figure 4, the moving region of acting umbrella 44 is A, and the moving region of acting umbrella 48 is B.Two acting umbrellas slide on same track rope 43, but can not bump together.Because connect the moving region A that the acting rope 43 of acting umbrella 48 needs by acting umbrella 44, on design acting umbrella 44 block 45 and on need consider to allow when short tube 46 and following short tube 47 acting restrict 43 freely to pass through.
As shown in Figure 5, restrict 52 in the rotating shaft 53 of generator 51, drive the working procedure that generator 51 rotates for acting.
As shown in Figure 6, for being the complete umbrella that can be used to generate electricity a ladder system.It is by guiding kite 61, two load umbrellas 62, acting umbrella 63, and track rope 64 and acting rope 65 and generator set 66 are formed.Ordinary circumstance lower railway rope 64 will be fixed on the object on ground, and acting rope 65 may be in a rotating shaft.Guiding kite 61 also can replace by may float on aerial balloon, and acting umbrella 63 can be more than one.
The number of umbrella increases as required.The purpose that increases the quantity of umbrella is in order to increase the overall blowing area of system, thereby produces bigger pulling force.
The quantity of umbrella can reach tens even hundreds of, depends primarily on the length and the intensity of track rope.
The utility model provides a kind of method and system that effectively utilizes wind energy.This system produces extremely powerful pulling force, can be widely used in generating or promote weight etc.
Those skilled in the art do not break away from essence of the present utility model and spirit, can there be the various deformation scheme to realize the utility model, the above only is the preferable feasible embodiment of the utility model, be not so limit to interest field of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all is contained within the interest field of the present utility model.
