Mini-GES – gidroenergoprom Leneva

Design gidroenergoprom Leneva

Description of the principle of operation mini-hydro

## Mini-GES – gidroenergoprom Leneva:

Mini-GES – gidroenergoprom Leneva N. And. uses original, not previously used in any of the existing structures, the method of obtaining energy from a water flow of any kind (rivers, streams, tides, sea waves, etc.), so the movement of air masses. This uses the natural flow, without a conversion (construction of dams, canals, pressure pipes).

This method of obtaining the power of the water flow is the most favourable from an environmental point of view, since it does not disturb the natural bed of the river, occupying from 1% to 10% of the area, thereby not preventing the free movement of river fauna and flora in contrast to the existing hydroelectric plant.

At a flow velocity of the river is 1 m/s gidroenergoprom Leneva N. And. size 1,5*0,7*0,6 m produces 11 kW.

## The design of Leneva gidroenergoprom:

Mini-GES – gidroenergoprom Leneva is a system (two rows) of blades of rectangular shape (flat plate) whose axes are divided into two (1/2) is not equal parts, most of which always (due to the action of a stream) is located behind the axis further downstream. Thus the minimum rotation around its axis and, hence, the smallest turbulent eddies.

The blade axis, its upper and lower parts, in turn, is fixed to the upper and lower, closed in a ring – chains BPD (or any other flexible element). Chains transmit force through the sprocket (working wheels) two vertical shaft from which mechanical energy of the moving medium (water, air, etc., etc.) via a flexible coupling and intermediate shaft is transmitted to the shafts of generators. Shafts through the bearings (rolling) rigidly secured to the frame gidroenergoprom, having closed on the 2/3 side and remote lower wall that prevents the flow of additional water from the ambient flux through the top and 1/3 of the side walls of gidroenergostroy.

In a single frame efficiently accommodate at least three block the installation of mini-hydro.

The position of the blades relative to the main flow governed by stationary guide rails for the chain and moving to the larger of the sides of the blade and by changing the distance between the movable guide blades and the stationary chain, we set the required angle of rotation between the blade and the direction of the main stream from 00 to 450, thereby achieve the optimal regime of work of gidroenergoprom or stopping it completely. Thus, the flow acts on the blade is actually perpendicular, 900. One of the shafts gidroenergoprom has a tensioning device for regulating the tension of the chains. The blades should have the freedom of rotation on their axes, and the axis as freely rotatable in the fastenings to the chains. Between the blade and the mounting location of the circuit on the axes should be installed the rollers that will roll along the fixed guide, thereby keeping the chain constantly perpendicular to the direction of the main flow.

Block sizes mini-hydro is not limited. Determined required capacity and size of the river. As an example, take: width – 1200 mm, depth – 700 mm, length – 1250 mm, i.e. a volume of 1 m3. It allows you to place it 3 settings with 17 blades, each having in turn: – width – 150 mm depth – 500 mm, i.e. each area of 0.075 m2. As the two blades will always be on the turns, then the total working area a single installation of gidroenergostroy – 1,125 m2, the sum of 3 plants mini-hydro within one frame (1 m3 of flow) will – 3,375 m2!!!

The frequency of rotation of the shafts – a total of 30-60 rpm.

Such construction of gidroenergoprom can make full use of every cubic meter of flow of the moving medium, the generated centrifugal and centripetal acceleration increases as the velocity of flow and the gravity is divided into sections of flow of the moving medium, in our case the river.

The consumption of one kilowatt mini-hydro, depending on the materials used for manufacturing will vary from a few hundred grams (plastic, ultra high molecular weight polyethylene) up to 2-3 kg (steel) per 1 kW of installed capacity.

## Description of the principle of operation mini-hydro:

Gidroenergoprom Leneva N. And. creates front a small backwater of 10 cm at a flow rate of 1 m/sec. and for a vacuum and because the blade is water falling from this backwater, the effect has a different velocity than the surrounding flow. If there are some on and off at the output, mini-hydro flow under the action of centrifugal force and the gravitational constant increases its speed! What is not difficult to see in the photographs overlooking the stream and the breaker, which it creates. Gidroenergoprom works like a pump.

## The advantages of gidroenergoprom Leneva:

– increased the working area of gidroenergostroy. To install mini-hydro there are no blades, which wouldn’t work at any given moment and against the other. The blades are set in two rows, each of which is a work. The double – blades are also working

form creates modularity of gidroenergoprom that allows you to build larger hydropower plant from miniblock for small, medium and large customer

– operating blades of gidroenergoprom located relative to the moving stream at an optimum angle of 45 degrees. Thus, mini-hydro is not only stops the movement of the water, taking from her all power, but also provokes the appearance of additional forces, significantly increases the power of the water flow, and, respectively, and our installation of mini-hydro. So at a rate of flow of the river of 1 m/s the installation of mini-hydro size 1,5*0,7*0,6 m produces 11 kW

– safe for the environment

– uses two shafts with a variety of blades that allows to concentrate the mechanical energy of chain (a cable, a tether, tape, etc.) and removes the need for manufacturing blades, shafts and other elements of special strength and accuracy.
