Wind and hydraulic unit with oscillating vertical blades

FIELD: power industry.

SUBSTANCE: main and auxiliary vertical double blades are arranged on a turning cantilever. The axis of the main blade in a central part is connected to a casing on the cantilever end with a return spring, and its planes are fixed asymmetrically on the axis, i.e. with a larger surface area towards the cantilever attachment centre. The auxiliary blade has symmetrical planes and is kinematically connected to the main one through transmission ratio providing a larger turning angle to it. A multiplier is of combined type, and it has additional inner conversion relative to slow back-and-forth movement of the cantilever axis to increased one-way rotation of a multiple-pole generator. In case of an underwater design, axes of blades and cantilevers are equipped with waterproof sliding bearings excluding the need for additional sealing of inner volumes of the blade part of the cantilever and the load-carrying housing.

EFFECT: invention contributes to creation of surface and above-water, noiseless and safe wind driven units, as well as bottom hydraulic units in river, running and sea streams providing simple and compact designs with possibility of their being lifted to the surface for periodic inspection or repair.

The invention relates to renewable (alternative) energy and can be used to create new types of efficient and inexpensive wind and hydro installations of different capacity, working in free air or water streams.

The known device for PTO in a fluid environment (1), wind and hydro power plants with oscillating wings (2), the device for selection of wave energy (3) is given at the end of the description. However, these designs are less suitable for creating effective wind and hydro installations of different capacity.

An object of the invention is the creation of a quiet, safe, ground and surface wind turbines, and placed in the field of river flow and sea underwater currents hydro installations that do not require in General high-tech industries and relatively high financial costs for their development and production.

This objective is achieved in that the rotary console installed the main and auxiliary vertical blades, ensuring their effective teamwork with simultaneous simultaneous reversal of their planes in the extreme positions on the optimal (but different) angles of attack to the flow, which allows the beginning of their reverse movement almost from the maximum torque. Once edenia bearing overrunning the left and right rotation is not at the entrance of the combined multiplier, and in the interim internal links can significantly reduce their overall dimensions and weight due to the ability of the application to him many times smaller torque effort. The absence in the planes of the blades of complex Aero - and hydrodynamic profiles simplifies their manufacture and, in General, significantly reduces the cost of such installations.

From patent and scientific and technical information the author is not known sources containing information about the same technical solutions that have similar characteristics with the claimed solution.

Figure 5 - positions of the blades in air or water streams.

The system includes a rotary console 1 with EN-hermetic casing 2 a streamlined shape, which is placed on the vertical axis 3 main and auxiliary 4 blades. Console 1 is planted on the vertical axis 5 and additionally Ude is zivaetsja cable 6 with stretch lanyard 7 1.

Bearing housing 8 is placed on the rack 9 with base plate 10 and is held stationary using a cable (or rod) extensions 11 with tensioning turnbuckles 7, and the generator part is located outside of the sealed connector 12 power cord 13. The lower part of the axis 5 is placed at the top of the housing 8 and is connected through external sealed bearing 14 and the bearing roller bearing 15. On the lower end of the axis 5 planted a large cylindrical gear with number of teeth Z1which engages with the side small cylindrical gears Z2and Z12. Gear Z2through two satellite shaft and an overrunning clutch left rotation of 16 kinematically connected with the bottom of a large bevel gear Z3. Accordingly, Z12the medium is identical to the shaft and an overrunning clutch 17 right rotation is associated with a similar gear Z13. Additionally gear Z3and Z13interconnected by means of small bevel gears Z4and Z14and the transverse shaft with a large bevel gear Z5. Gear Z5geared low output bevel gear Z6connected through inertial overrunning clutch 18 with multi-pole generator 19.

In the hermetic casing 2 size of the received return spring 20 and the node kinematicheskoi connection of the blades 3 and 4, having two versions. In the first (figure 3) this communication is done with the help of a large bevel gear Z7intermediate bevel gears Z8and Z9with the shaft 21 and the small bevel gear Z10and the second (figure 4) by means of rocker arms 22 and 23 of different lengths pivotally connected with them rods 24 and 241the same length. In the casing 2 also posted angular lugs 25 and 251limiting the rotation angles α1and α11blade 3 (figure 5).

Hour 9 and the base plate 10 in the wind turbine may be missing when placing it on the mast.

Windproof and water systems is as follows.

The assembled unit is housed on level ground. Bearing housing 8 is fixed in a vertical position using a cable (or rod) of the extensions 11 and finally leveled by means of turnbuckles 7. Similarly exhibited optimum tension on the console 1 cable (or rod) 6 using the lanyard 71. Sealed connector 12 power cord 13 is attached to the bearing housing 8. The axis of the console 1 turns the thread into position. Further circular orientation on the flow (mainly air) within 360° is carried out spontaneously, according to the directional principle.

Further rotatable within an angle αp(5) onsole 1 shows the installation of the operating mode. The plane of the main blade 3 with an offset axis of rotation are substantially larger area side flow, therefore, due to the differential acting on its plane forces FTthey will reverse the flow axis of the console 1 at an angle α1(or α11), limited by the stop 25 or 251. Accordingly, kinematically associated auxiliary blade 4 will be at a greater angle α2(or α21).

The joint operation of the interconnected blades significantly increases the efficiency and capacity of the installation as a whole.

Simultaneous reversal of the blades in the extreme positions A1or a3and the beginning of the movement of the console 1 in the reverse direction is performed as follows.

When approaching, for example, moving the left console 1 to the position α weaker return spring 20 will be compressed and to expand the blade 3 for the initial alignment of its planes and the attachment point of the spring 20 is sealed to the casing 2 with the axis of the console 1. At the same time under an angle α4to thread the blade 4 contributes to the continuation of the movement of the console 1 to the position And3by increasing the angle α3sufficient for further reversal of the flow of the blade 3 in position III1(shown dotted) at full angle α111. Dependent blade takie synchronously expands at a greater angle α 221(shown dotted). Arranged in position III1both blades provide the beginning of the reverse movement of the console 1 with almost maximum effort. The reversal of the blades in the position of A1(right) is similar, and so on

A selection of useful power is combined multiplier (figure 2) as follows.

When moving the console 1 to the left gear Z2rotates clockwise and through mud overrunning clutch 16 and the satellite shaft transmits torque to the gear Z3while the overrunning clutch 17 is open and the gear Z21rotates idle. When moving the console 1 to the right gear Z21rotates counterclockwise and through the closed overrunning clutch 17, and the satellite shaft transmits torque to the gear Z31while the overrunning clutch 16 is switched off and the gear Z2rotates idle. Bevel gear Z4, Z41and Z5together with the transverse shaft do so only one-way rotation. Then through the output bevel gear Z6and inertial overrunning clutch 18, the torque is transmitted to the multi-pole generator 19 with a magnified angular velocity ωrwhich (as viraat the applied power) proportional to wind speed or water flow.
