The invention is intended to convert the energy of the current environment in electrical and relates to hydropower, for example, rivers, tidal and other currents, as well as the energy of moving air masses in electrical or mechanical rotation of different devices.

It is known a device for converting energy of the current environment in the electric, containing a support, on which is mounted a generator on the shaft of which is fixed a pulley with a groove and posted in the last endless rope with a fixed floating elements made in the form of parachutes with elastic domes and slings, with the aim of increasing reliability by eliminating interaction domes with a pulley each chute is provided with a flexible connection between the top of the dome with a rope and pulley is mounted horizontally SU # 1295024, F03B13/12, publ. 1987.03.07).

A disadvantage of the known device is that part of the device is located above the surface of the water, and jump in the water, which reduces the efficiency of the device because of the resistance of the transition from one environment to another.

It is known a device for converting energy of the current environment, immersed in the past along the course of the stream and containing a working body in the form of an endless flexible chain, covering the pulley rigidly associated with the shaft of selection of capacity the spine, and blades, representing parachutes associated with the endless flexible circuit and configured to disclosure under the pressure of the stream environment and folding during the reverse course (US No. 3887817, F03B13/10, publ. 1975-06-03).

It is known a device for converting energy of the current environment, immersed in the past along the course of the stream and containing a working body in the form of an endless flexible chain, covering an exploded side from each other pulleys, one of which is rigidly connected with the shaft of the PTO, as well as parachutes associated with the endless flexible circuit and configured to disclosure under the pressure of the stream environment and folding during the reverse course, with the parachutes are equipped with balls filled with light gas in relation to the environment, to position the parachute up in the position of the stroke of the flexible circuit (US No. 4124182, F03D5/00, F03D9/00, F03D5/00, F03D9/00, B64C31/06, publ. 07.11.1978).

This decision was made as a prototype.

The disadvantage of this device is the imperfection of the design in terms of ensuring the engagement of the chain with the wheel. In the famous decision of the circuit is performed with hooks that should be included in the recesses in the Central part of the wheel. As the device operates in the water, the chain and wheel become slippery and engages the chain wheel is broken, which reduces the efficiency of newsminute.american constant rotation of the wheel and its associated output shaft.

Achievable technical result is to increase operational performance by providing a guaranteed flexible engagement element with pulleys and exceptions braking flexible element and parachutes when passing pulleys or sprockets.

This technical result is achieved in that in the device selection energy of a fluid medium, immersed in the past along the course of the stream and containing a working body in the form of an endless flexible chain, covering spaced at a distance from each other of at least two toothed pulley or sprocket, or belt, covering spaced at a distance from each other of at least two pulleys, with at least one toothed pulley or sprocket endless flexible chain, or the pulley belt is rigidly connected with the shaft of the PTO, as well as parachutes associated with the endless flexible chain or belt and made with the possibility of disclosure under the pressure of the stream environment and folding during the reverse course, according to the invention the toothed pulleys or sprockets endless flexible chain or belt pulleys positioned in the current environment in a horizontal direction from each other with the possibility of rotation around its axis and each of them is made with elements of engagement with the specified chain, or with the specified belt, which is mounted or to which estco attached sleeve, in each of them with the possibility of rotation around a vertically oriented axis installed the truss element is attached to the corresponding chute.

In addition, the parachute can be fitted with each bulb filled with gas lighter environment.

The present invention is illustrated in the schema.

figure 2 shows a General diagram of the device used for the aquatic environment;

figure 3 - example of execution of the node of the reversal of the flexible link;

Fig. 4 is the same as in Fig. 3, the cross section;

Fig. 5 is the same as in Fig. 3, top view.

According to the present invention is considered the unit of energy extraction fluid, immersed in the past along the course of the stream and containing a working body in the form of an endless flexible chain or belt 1, covering at least two spaced apart in a horizontal direction at a distance from each other pulley 2 or stars made with a brook laying the specified chain or belt and gear with him. At least one of the pulleys or sprocket is rigidly connected with the shaft 3 of the PTO. Parachutes 4 are connected with an endless flexible chain or belt and configured to disclosure under the pressure of 5 flow and folding during the reverse course. Parachutes 4 is equipped with every bead/ball 6, Zap linenum gas lighter environment. Pulleys or sprockets positioned in the current environment in a horizontal direction from each other with the possibility of rotation of each of them around its vertical axis, and each of them is made with elements of engagement with multi-grooved belt or chain, which is mounted or to which is rigidly attached to the sleeve 7, in each of which rotatably in the sleeve around a vertically oriented axis is selected rod element 8 type of leash D-shaped, is attached to the respective chute 4.

Positioning belt and pulleys (asterisks) in the horizontal direction leads to the fact that parachutes are height in a flat stream of air or water, which eliminates the negative impact on the operation of the belt due to the difference of flow parameters at different levels. In addition, given the dimensions of the parachutes, eliminates the need to control the position disclosed and folded parachutes at an altitude of installation.

The shaft is connected with the built-in electric or hydromachines.

The unit of energy extraction fluid converts the kinetic energy of a moving stream environment (air mass or water flow) and consists of a flexible body, which can be made in the form of a chain, or reinforced, for example Kevlar Toros, wedge-shaped or toothed REM is I 1, or metal or polymer chain, on which are fixed through rotating in bushings 7 leashes attached parachutes 4, have to ensure that balls up 6 filled with gas lighter environment to maintain the chute in the raised position throughout the trajectory of their movement. Alternatively, the parachutes can be sewn and made hollow and filled with light gas, but it is necessary to consider their dimensions in the folded position. The chain or belt moves in a circle at least two mutually spaced in hand gear or simple pulley 2 or the stars of the transmission elements at the expense disclosed in the flow of water or air parachutes 4. When moving belt or chain drives the pulleys 2 or sprocket and rotate the shaft 3 of the alternator, pneumatic or hydraulic machines, which are enclosed in a sealed casing 9. To prevent the ingress of water into the internal volume of the output shaft of the Cup housing 9 is closed by the bell 10, which rotates with the shaft in the housing to align the internal pressure with the external pressure of the pumped air or gas (helium or hydrogen). Thereby eliminates the need for elements of tightness (cuffs) and in a solid body.

To get into the housing 9 (variant of its placement in the aquatic environment) and maintenance work at the top of the glass under it is locolor 10 may be arranged hatch or door 11, not to dive in scuba gear, and to get from the water surface (ladder options on land). The enclosure can be connected by a pipe (tunnel) with a lock chamber and a pressure chamber for the passage of decompression.

The device operates as follows.

At least two spaced to the sides of the pulley 2 (asterisks) are positioned in a moving stream environment on supports (not shown) or by the lifting force of the wing (not shown) of the balloon 12 (filled with gas lighter environment) on the rope (chain) braces 13, fixed in the ground, or screwed into the anchors 14 or anchors across the stream, and the distance between the pulleys 2 (stars) is determined sufficient to prevent tangling of parachutes opposite branches, and the depth is sufficient to ensure the smooth passage of vessels. The pulleys 2 interconnected or rigid frame 15 (Fig. 3), or cable 16, which is stretched side stretch marks. The pulleys 2 (asterisks) wearing the belt 1 (chain), which parachutes 4 is driven via a l-shaped metal leashes, rotating in the sleeve 7 mounted on a belt or chain and ensuring proper passing over the end surface of the pulley (sprocket) and the top edge of the belt or chain. When the parachute at the end point of the belt 1 moving in the opposite direction, through the leash, crepe is different to the center of the dome of a parachute, changes the direction of movement of the chute that leads to its collapse. This changes the resistance movement of the parachute to a minimum when moving against the current. Upon reaching the parachute pulley or sprocket his leash, freely passing through the end surface of the pulley that goes on the cross-flow section of the chain or belt, pulling the parachute, which stands sideways to the flow, in the same way passes and the second traction leash parachute. When driving in cross section to prevent excessive deflection of the belt might place additional one or more pulleys 17, which can be attached to the cables or the frame between the main pulley. When positioning the pulleys close to the ground surface to prevent contact with him belt or parachutes possible the production of one or more pulleys that will fix the path of movement of the belt. When driving folded parachutes in the opposite direction, so that sagging of the sides are not confused, they can be made according to the type of thread "spandex", due to the rubber thread to be pulled together when the parachute goes. To prevent twisting of parachutes around the belt or chain they must be lighter than air (water), which can be achieved at the expense of the balloon 6, filled with light gas (for the water the air is m), or parachutes custom made hollow and filled with gas or through floats foam, for example. Moreover, by increasing the movement of the belt 1 (doshkilnoi scheme), that is, it is not simply triangular in plan parallel to the flow, and will seek up that can give great traction force. To increase the amount of gas will change the lift force that will affect the trajectory of the contact area of the belt 1 with the drive pulley of the generator, and to correct his slip of the belt can be made multi-bilateral and clamped the second pulley 18 on the shaft set gear coupled to each other. The pulleys and belts may be serrated. As the pulley may have a minimum diameter, the smaller is, the more its speed and when applying the low-speed multi-pole generators eliminates the need for the formulation of the reduction gearing of a multiplier, which significantly increases the efficiency. When using modern parachutes installation can be quite easy and cheap.

Under the action of a stream environment (water, air) elastic parachutes on the working branch endless chains take the form of domes parachute, and on the other branch of the chain is formed, the result is the force driving the chain that spins the wheel and a fixed power is enerator.
