The prototype can be patent No. JP 60-45786 A, 03/12/1985, F03B 17/02. The prototype represents an energy system with forced acceleration of the water flow using gases entering the cylinder filled with water as explosion products, and the gases pass through a system of gratings, vertically into the water flow, dragging water upstream, thereby creating a flow in the central neck, on peripheral part of the tank. The turbine is located in the lower part of the neck in a reverse flow stream.

The presented device is characterized in that the power flow creates two horizontal whirlpools separated by a divider, in the edge of which a turbine with a horizontal axis of rotation is installed. The rotation of the turbine is transmitted to a generator located outside the pool casing.

The essence of the proposed device lies in the fact that the cylindrical pool, in which the water flow is forced to force a horizontal plane, contains an acceleration device along the flow axis, on the one hand, and a flow divider, on the other side of which a horizontal rotation turbine axis is fixed, and the gearbox and the generator is taken out of the pool, in addition, oval-shaped abutments are placed on the sides of the stream, their shape contributing to the formation of two whirlpools around the abutments and along the side walls of the pool Directing the flow again under a stream of acceleration devices.

The power unit allows operation of a hydraulic turbine without dams and dams, on an artificially dispersed stream, in a closed cycle of a horizontal stream, in a special form of a cylindrical basin. Acceleration of water, its speed and the method of selecting the kinetic energy of a stream for transmission to a current generator - these are the parameters that determine the power of a hydroelectric power station with a forced flow, for example, from a blast wave.

This application considers a device with a divided, looped-through two streams of artificially dispersed water, then energy is taken and transferred to a current generator.

A device for generating electrical energy in a closed stream of water with forced acceleration is illustrated by drawings, where:

Figure 1 - Model of a horizontal cylindrical block operating on the strength of the kinetic energy of the blast wave, divided into two whirlpools.

Figure 2 - Section along the transverse diameter.

The model of Fig. 1, Fig. 2 (micro hydroelectric power station on a blast wave) of the horizontal type works as follows: on the axis of the accelerated flow in the horizontal pool 1, outside it, an accelerating device 2 with an explosive chamber 3 is installed. Water getting into the end cavity of the device with by the force of, for example, a blast wave, is directed between two lateral oval-shaped abutments 4 onto the blades of the turbine 5, which is mounted on the edge of the divider 6. The divider 6 divides the flow into two arms, directing it to both sides of the pool 1, which then again falls beneath the accelerating stream. It turns out two whirlpools, combining forces and acting on the turbine blades. Gear 7, generator 8 are displayed outside the pool along the flow axis. Acceleration of a liquid to transfer kinetic energy to it can also be carried out using a blast wave, for example, from microprojectiles of explosives produced in chamber 3, gases act on water, but the combustion products do not pass through the water stream, as in the prototype, they go into the atmosphere or cleaning chamber.

Thus, the kinetic energy of the dispersed fluid through the rotating turbine 5 in contact with the fluid flow and through the reduction 7 causes the generator 8 to give current. The only problem is that the energy costs of dispersing the liquid in the pools used are as low as possible, and the energy obtained in this case is greater.

In winter, the pools should be freezing liquid or salt (sea) water.

The technical result obtained from the invention is that the proposed hydroelectric power plant scheme, in particular, as a way to obtain energy from a closed flow with forced acceleration, is a fully autonomous energy complex, does not require dam and derivational pressure and direct proximity to the rivers. The device can easily be energetically connected with other types of alternative energy (wind and solar), creating a combined power system using renewable energy sources.

Hydropower plants with a closed reversible cycle of water movement in a horizontal basin have obvious advantages, since these types of micro- and mini-hydropower plants can be located in close proximity to production facilities and other consumers and are individual renewable energy sources.

The device, its shapes and sizes allow placing hydroelectric power stations both at large enterprises, in workshops, basements, technical floors, and in private houses and summer cottages, naturally corresponding to the size of capacities. The device is rational, economical and may be necessary, created in the factory, the product for sale.

The actual possibility of factory manufacturing of micro-hydroelectric power stations for this method and selling them to the population in assembled form as a consumer goods product.

Experimental experiments and devices have shown that the method of dispersing water and the device has the right not only to exist, but will also give a wide range of applications in everyday life, in any production and economy, in industry and in transport. The simplicity of the device and the model breadth of the types of devices will make it possible to widely use them to obtain electricity in all regions where there are no rivers, seas, fuels, and other expensive types of energy, while micro hydroelectric power stations (up to 300 kW) can be manufactured in assembled plants in a single set , with a pool diameter of up to 30 m. The device allows the use, as an option, of pressure derivations of natural flows with a pressure of at least 3 bar.
