Description

WIND-POWER PLANT

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention has to do with wind-power engineering and can be used

in producing and accumulating of heat and electric power of industrial and

consumer purposes, and also for gear of pumping and compressor stations,

circular saws and power-saw benches, mills, oil-mills and other power

establishments.

2. Discussion of the Prior Art

We know wind wheel of sail operation with the vertical shaft that

works in a block with an electrical generator. It has semi-cylindrical

blades connected with the vertical shaft by upper and lower horizontal

traverses. Between these traverses, there are vertical posts

supplied with regulation weight with a pawl and guide lath. More over, the

weight is installed with the capacity of traveling along the lath [1] .

We also know the wind-power plant that is more similar to this one by

purpose and the whole complex of indications. It contains wind wheel

connected with the pump kinematicaly. This pump has suction branch pipe and

pressure one, electrical generator with its hydro-conductor, heat

accumulator, heat exchanger, circular pump and connecting mains [2] . The problem resolved by this invention is the lowering of power force

that counteracts to the rotation of the wind wheel during the blades' motion

towards the contrary wind and increasing the capacity for transformation the

energy of wind wheel with the compact construction of the plant.

This problem is resolved because, in contrast to well-known power-wind

plant that consists of wind wheel connected with the pump kinematicaly, has

suction branch pipe and pressure one, electrical generator with its

hydro-conductor, heat accumulator, heat exchanger, circular pump and

connecting mains, in our plant, the wind wheel has a form of a couple of

blades that form, in a plan, S-formed configuration with the center of

mirror symmetry by rotation axle, where the blades are fixed. On their

convex surface, wind-reducing structure is formed, and, on the remote one,

the heater is done as the heater YUSMAR that is inserted in hydraulical ly

locked circuit of pump, its pressure branch pipe, heat generator,

hydro-conductor of electrical generator, heat accumulator and incoming

branch pipe of the pump. Wind-reducing structure is a cell covering of

elastic material, travelling locally relatively to the blade's surface.

This surface forms binary combination like a combination in a golf

ball. The rotation axle of the wind wheel and inertial weights on the

blades are shielded against the wind blades that counteract the rotation. SUMMARY OF THE INVENTION

The technical result achieved by this invention is to reduce the

influence of the contrary wind that counteracts blades rotation and

increase heat and electric power of the plant as it has compact, hard and

easy construction.

It is secured by convex and concave form of the blade with the wind

reducing structure by convex surface that is like a structure of a golf ball

[3] , shielding inert ial weights and rotation axle of the wind wheel

against the contrary wind, and, also, by installing the heat generator

YUSMAR in the hydraulically locked circuit for transformation the wind wheel

into heat and electrical energy.

Over it, the heat generator YUSMAR means aggregate b^'ised on the

high-speed driving of the liquid in a closed volume and sharp braking of it

in

this volume that, according to the law of thermodynamics, brings the rise in

temperature and liquid pressure. The heat generator YUSMAR, that is one part

of above-mentioned wind-power plant, is known by its high properties of

transformation [4, 5] . The wind-reducing structure means cell covering as

fixed on the convex surface of the blade mechanically so formed by

corrugating or something like this and covering the cells of .he material

with the spring property. - A -

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The wind-power plant is formed by wind wheel 1 that is connected with

it kinematicaly by mechanical gear 2, block of accumulation and energy

transformation 3 and direction block 4.

The wind wheel 1 consists of vertical rotation axle 5 fixed in a

bearing 6 and connected with the gear 2 kinematicaly. On the axle 5, a

couple of blades 7 is fixed. It stretches vertically and forms S-formed

configuration by its section(view in the draft). Over it, the convex surface

of one blade is conjugated with the convex surface of ano.her one by

pre-wings 8 that shield the axle 5 against the wind and other atmospheric

influences. On the tags of the blades 7 (relatively to the axle ) , there

are inert ial weights 9 shielded against the contrary wind by post-wings 10.

Along the whole convex surface of the blades 7, the wind-reducing structure

is formed, for example, like the mechanically fixed covering of polyethylene 1,5-10 mm with the cells 12x12 mm, cell pitch 20-25 mm and

drawing out degree of 4-5. The upper tag of the axle 5 has a bearing of

cruciform carriage 12 with the hipped stops 13 and pegs 14 for tension ropes

15 that have anchors 16 and regulation means 17 for tension ropes 15. So,

the wind wheel 1 keeps by bearing 6 and carriage 12 vertically. The bearing

is fixed on the axle 5 by tension ropes 15.

The mechanical gear with its brake knots of the rotation axle 5 and

regulation of the speed of rotation can be done in several versions. For

example, tooth of friction gear(knot), planetary mechanism, but,

nevertheless, it must satisfy the functional purpose such as transmitting

the energy of the wind wheel 1 to the block 3 of accumulation and

transformation of this energy. This block includes the pump 18 connected

with the gear 2 kinematicaly and incoming branch pipe 19 for suction of the

working liquid from the heat accumulator 20 through the hydro-main 21 of the

closed circuit and pressure branch pipe 22. This feeds the working liquid

under the pressure to the space( incoming) of the heat generator YUSMAR 23

then to the turbineds not shown) of hydro-gear 24 of the electrical

generator 25. The heat accumulator 20, heat generator 23, turbine of

hydro-gear 24 that is, like a pump, a part of the block 3, form hydraulic

circuit along the hydro-main 21 with the pump 18 and its branch pipes 19 and

22. The working liquid circulates by this circuit. For replenishing the working liquid, the tank 26 is connected with the hydromain 21.

Charge device 27, electrical accumulators 28 and current transformer

29 also come into block 3. With the electrical generator they form

consecutive electric circuit with the exit to the consumer of electrical

energy. The heat exchanger 30 is installed in the heat accumulator 20. It

has a form of coil with its main 31 and circular pump 32 for pumping over

the consumer medium( 1 iquid) through the heat exchanger 30 and then to the

consumer .

Regulation block unites the means of manual and programming ac ions

through the executive elements to the mechanical gear 2 and aggregators that

form the block 3. Constructively, the block 4 is a panel with the control

levers and buttons connected with the executive elements(is not shown), and,

for working in automatically conditions, there is mini-IBM or another

aggregate adapted to the concrete executive elements.

This plant is compact but, taking into account the rated power, swing

and vertical length of the blades 7 will be different for different powers.

The mass and occupied space of the bearing 6 and carriage 12 with the

hipped stops 13 will be different, too. y way, the plant is mobile and its

exploitation begins with the installing of the wind wheel 1. The verticality

of axle 5 is achieved by the influence over the regulator 17 of tension

ropes 15, that are hung up on the pegs 14 and fixed in the bottom by the anchors 16. Then, all blocks are installed in a whole energy diagram.

Installed wind-power plant works as the following.

During the interaction of the wind wheel 1 and the wind, with the

con¬

formity to physical law, the pressure of the concave surface of the blades 7

is always more then the pressure of the convex one. That is why even with

the

speed of the wind less than 4,0 m per sec, there always is a rotation

moment

for such blades. It is enough to beginning the work without additional

external starting influence. Reducing the moment that counteracts the

rotation of the wind wheel 1 is not only because of a concave-convex surface

of the blades 6

but also because of pre-wings 8. It helps to transform the contrary

wind into fair one by "streaming down" from the convex surface of one blade

6 to the convex(working) surface of another one 6.

When the speed of the blades is less than the given one, the block 4

of control regulates the short-term work of the wind wheel 1 by its

executive

elements in an idling rate. On coming out in_^ working rate, speed of

rotation swi tches on the mechani cal gear 2 that transfers thi s rotat ion to the pump

18

of the block 3. Here the mechanical energy of the wind wheel 1 transforms

into the rotation of the working liquid by closed circuit formed by the main

21.

Through the pressure branch pipe 22, the working liquid is passed tho

the case of heat generator 23. Here its motion and heating is done as it is

described in information [4, 5] : working liquid comes into injector branch

pipe, then into accelerator of the liquid-cyclone motion where is the

increase of the speed of liquid and its kinetic energy. Then the liquid with

the higher speed is thrown out to the brake element and out hole with a

small diameter in the case of the heat generator. It reduces the speed of

the liquid abruptly and rises the temperature and the pressure also

abruptly. Through the out nozzle of the heat generator this higher energy,

liquid is thrown out to the hydroturbine kinematicaly connected with the

hydro-gear 24 of the electrical generator 25. Its energy comes to the

consumer, coming through the electric circuit before. This circuit is formed

by the charge device 27, electrical accumulators 28 and current transformer

29. Hot working liquid passing the hydro-turbine from the case of heat

generator 23 by the main 21 comes into heat accumulator 20 where heats the

water or another liquid in the heat exchanger 30. Then, the pump 18 sucks is again and through the incoming branch pipe 19 it locks its cycle motion.

Heated in the heat exchanger 30 the liquid is pumped over by the circular

pump 32 to the customer.

Wind-power plant can work with any power-consuming mechanisms

individually and in the aggregate with another power systems, and also for

producing the heat or electrical energy, or as a mechanical branch pipe to

different aggregates: pumps for pumping over the liquid, power-saw benches,

mills. It is autonomous and does not need an external energy grant. It is

mobile, durable and can be used in different climate and atmospheric

conditions: if there is a threat of tornado, the wind wheel 1 can be

dismantled quickly.

While the working in automatic rate, when the speed of wind is higher

than it is given in program, the plant stops in the position of the biggest

streamlining - in a lateral projection of the blades 7 to the wind forming

the cylinder with the low sail operation.

According to this invention an experimental model of the wind-power

plant is created. Its total power is 15kW. The swing of the blades is 2250

their vertical length is 6000 mm. The work of this plant is stable if the

speed of wind is more than 4 m per sec. It occupies a small area is pure and

not exigent in exploitation.
