Abstract

Use, energy of river and sea currents. The catamaran pontoons have the shape of an isosceles trapezium. The nosal part of the catamaran is designed as a nozzle, the walls of which are mounted at a right angle to each other. The small trapezoid bases are facing the longitudinal axis of the device. The transverse turbines are installed between the pontoons. The bottom is installed between the pontoons and the gearbox to connect the turbine shafts and generators located on the pontoons. The nozzle is made folding Kormova part of the catamaran is equipped with a controlled sash. 2 Il.

Description

The invention relates to hydropower and can be applied when using the energy of river and sea currents.

A floating hydroelectric station containing transverse turbines installed between pontoons and generators is known.

The purpose of the invention is to increase the efficiency of hydroelectric power plants.

The goal is achieved by the fact that the HPP is equipped with a bottom installed between pontoons and gearboxes for connecting turbine shafts and generators, and the stern part of the catamaran is equipped with controllable cross-sections.

Figure 1 shows a floating hydroelectric station, a top view (the turbines are raised), figure 2 is the same, side view, a longitudinal section (the turbines are lowered).

The floating hydroelectric power plant contains a pontoon catamaran, whose decks and bottoms are shaped as isosceles trapezoids, with small bases facing the axis of symmetry of the hydroelectric power station, in strait 1 of which transverse turbines 2 are located, connected through a gearbox to generators 3 installed on the decks of pontoons 4, which are connected between an intermediate bottom 5, with

In this case, the bow of the vessel is equipped with a spreading rectangular nozzle 6, and the feed control valves 7, in addition, the C / 1 vessel contains frames 8 attached to the intermediate bottom, which perform j functions of the flow-guiding blades, and jacks 9 for installation of a waterworks on the bottom of the river in winter. There is also a waterline 10.

The floating hydroelectric station works as follows: N time

When a vessel is installed against the stream, the J jet 6, which forms a more enhanced f flow, which is additionally enhanced by QQ due to the opening of the wings 7 behind the stern, forming suction, which are lowered into this flow, receive more energy than the natural flow. torque transmitted to the generators 3.

The advantages of the proposed device over the known one are in the creation of an additional acceleration of the flow, which leads to the obtaining of a higher efficiency of the hydroelectric complex. In addition, the advantages are that the proposed waterworks can work in the winter when it is installed

at the bottom of the river by temporary flooding. The advantages also include the creation of favorable conditions for the traveling condition.
