Description

The proposed utility model relates to the field of energy, in particular to hydroelectric power plants located in the surface of the rivers.

Known surface hydroelectric power station (patent application No. 20111153596 2006)

The disadvantages of this hydroelectric power station are complex design features, the need to build a channel for supplying and discharging water, an accelerator for the flow of water, and a small width of the blades.

Known channel surface hydroelectric power station (ntpo.com> patents-electricity \ electricity-3 ...), containing the deck in the surface position.

The disadvantages of this hydroelectric power station are the huge diameter of the shaft and a large number of blades, the constructive arrangement of which creates the inefficient operation of the station and the difficulty in maintenance.

The objective of the proposed utility model:

- the possibility of sectional assembly.

The problem is solved in a surface hydroelectric power station consisting of a bed, a shaft, blades, a gearbox and an electric generator, while it consists of a section mounted on the platform and contains 5 rotating shafts located in a horizontal position, with 50 blades fixed on each 6 blades and a length of 10 m, with all the rotating shafts connected to the central shaft using a chain tape. The number of sections can vary from one to ten.

The sections of the surface hydroelectric power station are interconnected. Each section can work independently. The central shaft transfers rotational energy to the gearbox and electric generator.

The utility model is illustrated by drawings, where in FIG. 1 shows one section of a surface hydroelectric power station (top view) and the positions indicated:

1 - platform

2 - bed section

3 - rotating shaft

4 - blade

5 - chain tape

6 - the Central shaft,

7 - gear

8 - electric generator,

9 - manual lifting device for the bed.

In FIG. 2 shows a section of a surface hydroelectric power station - a side view and the positions indicated:

1 - platform

2 - bed section

3 - rotating shaft

4 - blade

5 - chain tape

6 - the Central shaft,

9 - manual lifting device for the bed.

In FIG. 3 shows the installation of a section of a surface hydroelectric power station in a river and the positions indicated:

10 - concrete block,

11 - cable

12 - legs

13 - the gate.

Each section of the surface hydroelectric power station consists of platform 1 of FIG. 1), on which the frame 2 is mounted with the rotating shafts 3 mounted on it and the blades fixed on them 4. The width of each blade is 50 cm, the length is up to 10 m, and the number of rotating shafts is 5 with 6 blades fixed on them. The length of the rotating shaft is from 5 to 10 meters. All rotating shafts 3 are connected by means of chain tapes 5 to a central shaft 6 without blades, to which mechanical energy is supplied from rotating shafts. All connections of rotating shafts using a chain tape are fixed on one side of the frame 2, and on the opposite side, opposite the central shaft 6 gear 7, which, in turn, transmits the mechanical energy of rotation to the electric generator 8. The whole frame 2 sections of the surface hydroelectric power station is installed on the platform 1, which is raised and lowered manually 9 of the lift in the ends 4 of the frame.

Each section of the surface hydroelectric power station operates as follows. A platform 1 with a bed 2 with rotating shafts 3 is immersed in water against the flow of the river at the level of the width of the blades 4 (Fig. 2). Under water pressure, the blades 4 will begin to rotate, together with the shafts 3 and their rotation with the help of a chain tape 5 will be transmitted through a gearbox 7 to an electric generator 8.

Depending on the fast or slow flow of water in the river, the transmission of rotation from the rotating shafts 3 to the central shaft 6 must be controlled using large and small sprockets (not shown in Fig.).

The number of sections of a surface hydroelectric power station can vary from one to ten.

The first section of the surface hydroelectric power station is fixed with the help of an "anchor" - a heavy concrete block 10 (Fig. 3), lowered to the bottom of the river and connected to it using cables 11 or chains. The length of the cables or chains can contribute to raising the section by 2-3 meters or more when the water level in the river rises, for example during flooding or floods. And it is also possible to make legs 12 on the platform 1 for insurance, so as not to land the section aground when the river is shallow, and to protect against ice drift, install guard gates 13 (Fig. 3) installed on the water in front of it at an angle of 45 degrees. The remaining sections are interconnected in different ways, forming a string of sections or a multi-section surface hydroelectric power station.

Small sections for individual users, installed, for example, on the Caucasian mountain rivers, which often after rains repeatedly rise in level, carry driftwood and trees, can be lifted to save from destruction using a manual lifting device 9 (Fig. 2).

The work of the proposed utility model of surface hydroelectric power is environmentally friendly, i.e. does not violate the natural ecology of rivers. It can be used both by individual consumers and on an industrial scale.

In addition, it is repeatedly effective, because uses the force of the water flow, for example, 10 meters long five times, i.e. actually 50 m long, due to the use of five rotating shafts in one section of a surface hydroelectric power station, i.e. the magnitude of the water pressure is determined by 25 square meters. m of water flow.
