Description

The proposed technical solution relates to damless power plants and can be used to obtain electrical energy from the flow of a moving medium, formed, for example, from a river, a canal and other bodies of water with a moving current (hereinafter referred to as a river).

At present, the design of used hydroelectric power plants (hereinafter referred to as HPPs) does not undergo significant changes and has reached the peak of its evolutionary development, however, the tasks of increasing the power, efficiency, and efficiency of HPPs are more acute than ever, due to the constant rise in fuel prices and its emerging shortages in many parts of the world.

Dam-type hydroelectric power stations are widely known, built on the basis of solid structures and having modules for converting the energy of water passed through the dam, however, their efficiency and operating efficiency are not high enough, and the design is complex and cumbersome and can not be used everywhere.

As a prototype, patent RU 187302 U1, February 28, 2019, can be adopted, which discloses the design of a floating mini hydroelectric power station containing a platform placed on two catamaran-type floats, a water wheel connected by a multiplier to an electric generator, a power line, stretch marks for attaching the platform to the shore lines, while the platform is U-shaped, on the sidewalls of which streamlined floats are placed on the inside, equipped with transport wheels from below, while in the central part of the platform there is an opening where the impeller with blades on supports is located, and in its front part - a removable handle for moving the mini hydroelectric power station along dirt roads and installing it in hard-to-reach riverbeds.

Its disadvantage is that the device has a fixed impeller, which makes it difficult to move the device to the place of energy generation (low mobility), the impeller cannot be submerged to a depth that excludes the resistance of the water flow against the body of the floating platform, requires a serious current for correct operation, which provides the device with low efficiency at low mobility and bulky design.

The basis of this invention is the task of developing a design of a rotary hydroelectric power station that eliminates these shortcomings of the known device.

The technical result is to increase the efficiency and efficiency of the device with simultaneous compactness and mobility.

This technical result is achieved by the fact that a mobile rotary hydroelectric power station, containing at least two floating boules connected by means of a frame base,

on the frame base, on the corresponding racks, the first and second horizontal rods are fixed with the possibility of rotation in the bushings,

the first horizontal rod includes a holder associated with it, including a rotor, a bevel gear with a rotor working shaft, as well as an output shaft passing through the holder, configured to transmit rotational motion from the rotor to the electric generator, while the holder also includes fasteners for fixing in them fairing around and across the width of said rotor,

the second horizontal rod interacts with the tension mechanism and contains a winding pulley with a cable connected to the rotor to raise and lower it,

the working shaft of the rotor is connected to the water divider, made, basically, in the form of a cone with sides rounded inwards, at least two support rings are placed around the water divider, on which profiled blades are installed, passing water through their surface to create a rotational movement rotor.

The tension mechanism is made in the form of a motor - reducer.

Fasteners are made in the form of eyelets with holes for bolts.

Profile blades are made with the ability to change their angle of inclination.

The mobile rotary hydroelectric power station contains at least two floating boules 1 connected by means of a frame base 2. The number of boules 1 must be at least two (boule on each side). For better buoyancy and stability of the device on the water, the number of boules 1 can be increased, for example, four, six pieces, etc. The material and shape of the boules 1 may be different and not limited to any execution, however, obviously, they must provide sufficient carrying capacity and stability on the water of the entire structure.

The frame base 2 is made in the form of a single frame, preferably rectangular in shape, for example, from a metal profile, to provide a single rigid structure of the device and perform the necessary tying of the device with its nodes and elements.

On the frame base 2, two pairs of racks 3 are made, in which the first 4 and second 5 horizontal rods are fixed with the possibility of rotation in the bushings.

The first 4 horizontal rod includes a holder 6 associated with it. The holder 6 in its design includes a rotor 9, a bevel gear 10 with a working shaft 11 of the rotor 9, and an output shaft 12 passing through the holder 6 to transmit rotational motion through these shafts 11, 12 from the rotor 9 to the electric generator 13. The bevel gear 10 is preferably made in the thickness of the holder 6 to prevent water from entering it and to ensure its easier rotation. The output shaft 12 also preferably extends through the body of the holder 6, for example in a corresponding internal bore thereof. The transmission of rotation from the output shaft 12 to the generator 13 can be carried out according to various schemes, both using additional nodes (gearboxes, shafts, gears), and directly from the output shaft 12 to the generator 13. The generator 13 may contain an alternating current generator and a rectifier unit, to equalize the generated electric current.

The holder 6 also includes fasteners 7 for fixing the fairing 8 in them, placed around and across the width of the rotor 9. The fasteners 7 are made, for example, in the form of lugs with bolt holes, to ensure reliable fixation and quick removal of the fairing 8, if necessary. .

The fairing 8 is made in the form of an outer casing covering the elements of the rotor 9 from the side to exclude the effect of water flow or waves or other external factors on the moving elements of the rotor 9 and impede the rotation of the rotor 9, to increase the efficiency and efficiency of the device. It is preferable to make the fairing 8 in the form of a truncated cone with its expansion along the width of the rotor 9.

The second 5 horizontal rod interacts with the tension mechanism 15. The tension mechanism 15 is preferably made in the form of a geared motor to increase the compactness of the device, reduce weight, and also ensure sufficient traction forces generated by this assembly.

The second 5 horizontal rod contains a winding pulley 14 with a cable 16. The design of the winding pulley 14 may be different, however, it is preferable to make the winding pulley 14 closed and/or with a guide for even winding, to prevent the cable 16 from slipping from it. The cable 16 is connected to the rotor 9 , to carry out its lifting-lowering during the transition of the device from the folded (transported) state to the working one, which increases the mobility and compactness of the device, including during its transportation.

Next, consider in detail the design of the rotor 9 (see Fig. 2). It should be noted that the water divider 17 in FIG. 1 is schematic.

The working shaft 11 of the rotor 9 is connected to the divider 17 of the water. The water divider 17 is made, basically, in the form of a cone with sides rounded inwards, under a certain bending radius. This rounding of the water divider 17 ensures that the water flow is redirected to the edges of the divider 17 on the shaped blades 19 to increase the efficiency and efficiency of the device. Profile blades 19 according to FIG. 1 are also not shown, but in FIG. 2 schematically shows only a part of the profile blades 19, which are distributed around the entire circle along the support rings 18.

Around the divider 17 of the water placed at least two support rings 18 associated with the divider 17 of the water. The number of support rings 18 may be more, for example, three, four, etc., which is primarily due to the width of the rotor 9 structure as a whole, to ensure sufficient rigidity of the installation of profiled blades 19.

Profile blades 19 are installed on the support rings 18, passing water through their surface to create a rotational movement of the rotor 9. The number of profile blades 19, their setting angle, the distance between them are selected based on the conditions of use of the device, the flow rate of the reservoir, the depth of the reservoir and other factors. Preferably, profile blades 19 are made with the ability to change the angle of their inclination in the support rings 18. The mechanism for changing the angle of inclination of the profile blades 19 can be different, for example, through their fasteners, capable of fixing the blades at different angles, or through various slots (slots with different angles of installation) in the support rings 18 or according to another scheme for changing the angle of their inclination. The presence and design of these profiled blades 19 improves the efficiency and efficiency of the device.

The principle of using the proposed invention is as follows.

- mobile rotary hydropower plant is launched into the water and moves to the desired point in the transported state (when the rotor 9 is raised up) or moves on the vehicle in the transported state.

- the mobile rotary hydroelectric power station is turned into the working position, for which the second 5 horizontal rod with the winding pulley 14 is rotated by the tension mechanism 15. The cable 16 is twisted from the winding pulley, which is connected to the rotor 9, and the rotor 9 is lowered into the water perpendicular to the floating boules 1.

- the water flow, entering the rotor 9, enters the water divider 17, through which the water changes its direction and tends to the outer edges of the rotor 9. The water flow at the edge of the rotor 9 passes through the shaped blades 19, passing water through its surface, thereby pushing rotor 9 in one direction to create its rotational movement.

- rotation is transmitted to the electric generator 13 to generate energy, through the working shaft 11, the bevel gear 10, and the output shaft 12.
