Description

Giant safety windmill

The present invention relates to a kind of wind energy conversion system, refer to a kind of giant safety windmill especially.

The energy output that has problems 1. of existing wind energy conversion system is unstable, and particularly the low 2. safety reliability of the utilization ratio of large scale wind power machine does not still have abundant guarantee 3. cost is higher.

As between the U.S. Pat 4245958 disclosed windmill flabellum assembling frame joints cross one another oblique support being arranged, limited the wider space of flabellum, and do not had anti-high wind and anti-accumulated snow facility to two wings, can not guarantee the safety of flabellum.

U.S. Pat 5195871 for another example, and its flabellum is difficult for not having the strong point in the middle of the reasons in structure that two wings extend is, the flabellum bar is fixed on one side of blade, and impact noise is arranged in the running, also is not durable.

The object of the invention is to overcome above-mentioned deficiency, and a kind of huge windmill is provided; Another purpose is to provide the safety control system of a kind of anti-high wind and anti-accumulated snow.

Realize first target, key is to confirm a kind of new theory:

1, flabellum be with long-pending little one-tenth multimode accumulation form the strength of these numerous flabellum generations " concentrating " in same vertical axle center, but the weight of flabellum, rock etc. collapsing force but " on average " be dispersed on the whole framework, the formation collapsing force does not converge.

2, the windmill flabellum is easy to the Xiang Eryi extension by vertical axle center, and axle center one wing leaf is level, the windage minimum; Another wing leaf of axle center is vertically, absorbs wind energy.Vertical flabellum absorbs wind energy and makes the wing tip that impacts flabellum, and this is the best mode that utilizes wind energy.

According to described principle, the present invention includes composite structure that flabellum extends to two wings and to the frame structure of high-altitude superposition.

For realizing second target, the invention provides a kind of safety installations that makes flabellum have anti-high wind and anti-accumulated snow.1. anti-high wind device includes: can counter-rotational reverse motor when installing one is at high wind in every section flabellum vertical central, and set up one and when high wind, make the relay and of reverse motor antiport have the blast switch of wind direction rudder action.2. anti-accumulated snow device includes: little gear motor, clutch, axle and gear.

The invention has the advantages that one, windmill can hugeization, two, anti-high wind and anti-accumulated snow device are arranged, make the flabellum operation more safe and reliable.

Now how further specify the present invention in conjunction with the accompanying drawings and embodiments realizes.

At first, see that Fig. 1,2,3 knows that the present invention can hugeization, flabellum was extended to two wings, can make flabellum again from level to level to the high-altitude superposition.Windmill shown in the figure is to be combined by eight stacking adding, and wherein every layer of framework be all by crossbeam 2 combined crosswise, is connected with column 8 between every layer of crossbeam joint 4, the connection block 6, and with iron 10 Joints, joint is connected with ground with cable wire 12 between the four joint levels.Its plan structure such as radial, advantage are anti-high wind.

Fig. 4 is combined in the make progress situation of superposition of flabellum combination on the flabellum axle center 20 and frame structure thereof.

One rotatable axle center joint 14 is arranged in the middle of every layer of crossbeam 2, and its upper end 16 and lower end 18 have a structure can be connected the fixed fan rachis heart 20, and axle center 20 is rotated in wind.Fan leaf is extended to two wings by flabellum axle center 20, and the intermediate intensity of strut 26 with reinforced blade established in the centre.

Fig. 5, flabellum bar 22 are the centres that are fixed on blade 24, make strut 26 with intensity between among the reinforced blade, and flabellum two ends bending relatively are an angle shape with blade.

Fig. 6, the signal wind direction, vertical vane absorbs wind energy, makes wind impact the flabellum wing tip, is the best mode that utilizes wind energy.

Fig. 7, the flabellum strut, a is situation against the wind, and b is situation with the wind, knows that from figure flabellum is combined in up and down between the level and connecting rod 28, be fixed with galianconism 30, vertical bar 32, be fixed with many adjutages 34 on the vertical bar 32 to support flabellum bar 22, supporting part has one 36, and fan leaf 24 is rotated along axle 36, when contrary wind, be the level of state, with the wind the time in vertical state.

Fig. 8, a kind of design that makes flabellum have anti-high wind, the

motor

38,40 that the running of two control flabellum horizontal vertical is promptly arranged in every section flabellum axle center 20, drive the flabellum of varying number respectively, wherein drive the motor 40 of lesser amt flabellum, when high wind, oppositely operate, to offset the wind energy that motor 38 drives more flabellum.

Realize that the control system of this counteracting running is included in relay 42, the 44 outer newly-increased relays 46 of the original clockwise and anticlockwise of control motor, to connect control forward and backward signal N.When high wind signal (for more than wind speed 20 meter per seconds) is opened relay 46, make former forward and backward motor all make antiport.

Fig. 9 shows the copper slip ring of blast switch structure and linking route and the device of anti-flabellum accumulated snow.

Wherein, the blast switch structure comprises rudderpost 48, bearing 50, wind direction rudder 52, and rudderpost 48 is coaxial with flabellum axle center 20, rotates with the wind, and is connected and fixed with bearing 50; Hang one 54 on the wind direction rudder 52, this lower end hangs the little flabellum 56 that can kick up with the wind, this upper end connects a little covering of the fan 58, little covering of the fan 58 and little flabellum 56 interlocks, when arcuation contact plate 60 touching sensitive switches 62, the circuit that leads to relay 46 is communicated with via the copper slip ring between the insulation disk 75,76 78, but the motor 40 of antiport when high wind is started and reaches anti-high wind control purpose.

In addition, the device of anti-flabellum accumulated snow comprises and is mounted on little gear motor 64, clutch 66, clutch shaft 68 and a gear 70,72 on the axle center 20, wherein 72 is fixed on the wind direction rudderpost 48.At flabellum accumulated snow and under the calm situation, the little flabellum of kicking up with the wind 56 in vertical state, arcuation contact plate 60 touches sensitive switch 74, make little gear motor 64 and clutch 66 start, this moment, gear 72 rotated rudderpost 48, rudderpost drives each section flabellum axle center 20 and rotates, and makes the running of blade vertical-horizontal, and reaches the purpose of anti-accumulated snow.

Wind direction rudder sensitive switch circuit is communicated with the motor control wiring of controlling the flabellum activities via being fixed in axle 48 the discoid insulating material 75 copper slip ring 78 relative with the insulation disk 76 that is fixed in axle center 20.
