(57) Abstract:

Use: hydropower and can be used in free-threaded hydropower plants. The inventive free-threaded hydroelectric power plant consists of the power shaft with movable relative to the blade shaft, mechanism for moving the blade with the roller holders. The blade is provided with a covering power shaft, a fixed casing with bridges, the connection of the energy Converter to the power shaft performed by the multiplier, while the blade and one of the bridges provided with teeth, and a mechanism for moving the blades are made in the form of a rigidly fixed on the power shaft of the flywheel with latches and installed above and below the two pairs of gears interconnected rollers, and the roller holders fixed to the flywheel, the tabs are located with the possibility of contact with bridges casing and the upper gear and the lower gear with the teeth of the blade. The blade is made in the form of a fabric membrane stretched over a frame, the upper belt is made with positive buoyancy, and the bottom is negative, while the belts are connected at the ends by uprights stiffness. When ice is ing perform two hole. The blade is immersed in the upper reaches of the hole using a rod and after her promotion under the top hole on the end of the blade is fixed upright support stiffness, and at the bottom of the hole down the power shaft of the power plant, and reducing thrust, roller holders mechanism for moving the blade slid free end of the blade, which then fix the second upright support stiffness. Free-threaded HPP allows to reduce the cost of energy, are environmentally friendly. 2 S. and 1 C.p. f-crystals, 8 ill.

The invention relates to hydropower and can be used in power stations on any river.

Known turbine:

1. Horizontal axis parallel to the flow axis (A. C. 11368477).

2. The horizontal axis perpendicular to the flow axis (A. C. 1661469).

3. Vertical-axis (A. C. N1712649).

4. Parachute (A. C. N1295024).

Device analogs have the following disadvantages:

able to work only at high flow velocity of 2 m/s or more, such rivers are shallow and shape of the turbine is not rational,

environmentally harmful, are the meat grinder for migratory species barrier in their motion,

do not provide for different speeds patlama-axial installation (A. C. N1642053). A distinctive feature of the prototype system are retractable blades. At the exit of the blade in the position associated thread it out of the drum, and after passing through the work area again slid into the drum. Drum up half buried in the tray mounted on the bottom.

The prototype has the following disadvantages:

the departure of the blade is limited by the radius of the drum and Vice versa, which makes the construction complicated;

the tray of the drum is constantly clogged with sediments;

underwater mounting tray and installation of roads;

a complex system of transfer of mechanical energy to the inverter, and if the generator set under water, then the necessary arrangements for sealing;

speed bottom minimum, which increases the inefficiency of the installation.

The technical result of the invention is to reduce the cost of energy, environmental consciousness.

This result is achieved in that the free-threaded hydroelectric power plant provided with a stationary casing with bridges spanning the power shaft, the connection of the energy Converter to the power shaft performed by the multiplier. While the blade and one of mostkovice with latches and installed above and below the two pairs of gears, interconnected rollers, and the roller holders fixed to the flywheel, the tabs are located with the possibility of contact with bridges casing and the upper gear and the lower gear with the teeth of the blade. The blade is made in the form of a fabric membrane stretched over a frame, the upper belt is made with positive buoyancy, and the bottom is negative, while the belts are connected at the ends by uprights rigidity.

The number of installed blades depends on the calculation of the efficiency of the power plant.

The claimed device is shown in Fig. 1, 2, 3, 4, 7, 8, and the way his latest installation in Fig. 5, 6.

In Fig. 1 shows the device power.

In Fig. 2 section a-a of Fig. 1.

In Fig. 4 section b-In Fig. 3.

In Fig. 5 shows the immersion of the twisted pipe blades into the hole.

In Fig. 6 shows the installation of the front stiffening.

In Fig. 7 the scheme of movement of the blade.

In Fig. 8 option of arranging the return mechanism (Fig. 3) when you install two blades.

Hydroelectric has a blade 1 having a rigid frame consisting of an upper belt 2, the bottom 3 is aNISM 7. The return mechanism consists of a flywheel 8, which is fixed to the upper 9 and lower 10 return gear connected to the connecting roller 11. To stop the top of the gear 9 on the flywheel are the tabs 12. Roller holders installed in the cheeks 13, attached to the flywheel 8. The flywheel is rigidly fixed on the power shaft 14, kinematically connected through the multiplier 15 energy Converter 16. The power shaft rotates in a stationary housing 17, is installed on the bridges 18 removing the fixing of the recoil mechanism. On one of the bridges have the teeth of the drive gear 9.

Hydroelectric works in the following way. The flow of water acting on the blade 1, causes the rotation of the shaft 14, which passes efforts on energy Converter 16. After the blade 1 rotates through 180o, wheel clamp 12 moves to the bridge 18, and outputs the latch of the clutch with the gear 9, on the other hand, the gear 9 come into engagement with the teeth of the bridge begins to rotate. The rotation of the gear 9 through the roller 11 is transmitted to the gear 10. In turn, the gear 10 being in engagement with the teeth of the blade moves it in the right direction, which helps the blade is moved progressively from nignog is ravnovesie and a new cycle begins.

In the inventive device can be used instead of the generator test hydrotherms locomotive (pin), then the mechanical energy of rotation is directly converted into thermal energy of the water. Free-threaded hydroelectric power plant adapted to be installed on the following supporting structure.

One of the mounting options free-threaded hydroelectric, when as a reference design uses the ice of the river.

The method for ice installation HPP in the following.

Before immersing the blades in the flow of its pre-rolled into a tube and in the direction of flow at a distance greater than the length of the blade, perform two-hole, the blade is immersed in the upper reaches of the hole using a rod and after her promotion under the top hole on the end of the blade is fixed upright support stiffness, and at the bottom of the hole down the power shaft of the power plant and reducing thrust, roller holders mechanism for moving the blade slid free end of the blade, which then fix the second upright support stiffness.

The method is as follows.

In ice Buryats two hole, and from one another in UAI pipe blade (Fig. 5). Strands 19 of the belts are secured on the ice. The blade down into the water, takes a horizontal position and turned around, send free end to the bottom of the hole. Under the influence of the difference of the floating qualities zones blade spins and takes the desired spatial orientation. Then at the end of the blade below the upper hole set rack stiffness 4 (Fig. 6). The front stiffness equipped with lower latch 20, top 21, studs and nuts 23. Hour is set as follows. The lower fork hour is put in the slot of the upper belt, which is aligned vertically with the guide channel 5 of the tissue membrane. Falling channel, hour goes by with a fork clamps into the holes of the lower belt. Once in the hole, the latch 20 fire and hour fixed on the lower belt. Both the upper latch 21 coming out of the neckline of the top belt, disclosed and rest against the upper belt at the bottom. On pins 22 protruding from the cutout of the upper belt, brings the nuts 23, thus hour is fixed and in the upper zone. After that, downstream of the hole install the power plant. Weakening the fibers and directing the free end of the blade, her head is s return mechanism 7, it set the second rack stiffness 4 in the same order. By combining the appropriate phase of the recoil mechanism with the beginning of the teeth of the blade can be run in hydroelectric power. To do this, remove the tie rod and turn the blade from the top dead center position in the right direction.

The described method of mounting allows the use of power during peak energy consumption, minimizing labor costs for installation, if necessary, diving works and underwater device foundations.
