The invention relates to hydropower and is designed to convert the kinetic energy of the flow of river water into electrical energy.

The closest analogue of this invention is the bottom hydroelectric containing flexible shaft with mounted on it a few gidrokoles, one end of which rotates the generator set on the banks of the river, and the other end attached to a bearing mounted on nadonna wire rope and winches with cables (EN 94024157 A1, 20.08.1996).

The disadvantage of this known bottom hydropower is its inefficient and unstable, due to the unstable situation of the flexible shaft with gidrokoles in the stream of moving water.

The present invention is to improve the efficiency and instability bottom of hydroelectric power by stabilizing the position of the flexible shaft with gidrokoles in the stream of moving water.

The solution of the problem of achieving what okresni, one end of which rotates the generator set on the banks of the river, and the other end attached to a bearing mounted on nadonna wire rope and winches with cables, according to the invention provided with two bottom power cables, flexible shaft is perpendicular to the stream, and nadgorny the cable has two anchors: big and small, and the head part nadanova rope attached to the top of the triangular bracket that is welded to a large anchor, and the tail of the rope is attached to a small anchor through the bracket having the form of a bent toe skis, with location nadanova rope from the bottom of the river at a height, greater radius gidrokolesa, with large and small armature mounted for movement with the help of winches each of them corresponding to the bottom power cable for lifting on the shore of the entire system gidrokoles when they repair or during ice flow and return gidrokoles in the river.

While hydroelectric power plant has several flexible shafts and the same number of generators.

Moreover, for any two adjacent flexible shafts gidrokolesa installed with the possibility of the opposite rotation of these shafts.

In addition, GSA with flexible shafts.

The invention is illustrated by drawings, where Fig. 1 shows a bottom hydroelectric plan in the form on the right Bank of the river, in Fig. 2 gidrokolesa, a longitudinal section in a vertical plane, Fig. 3 - the same, front view.

Bottom hydroelectric can have dozens of gidrokoles 1, mounted on one or more flexible shafts 2, rotated about the bottom of the river, and hold for 2 anchors, one large and the other small. Each shaft 2 rotates only one of my low-speed generator 3. All gidrokolesa 1 mounted on a 4 wires forming the flexible shaft 2 which rotates the generator 3, set on the banks of the river. One end of each shaft 2 is fixed to the power shaft in the power house, and the other end mounted in the swivel-bearing 4.

The bearing 4 is fixed by the length of the cable to the bracket 5, is welded to the metal plate 6. This plate 6 is perpendicular to the bracket 5 is welded two brackets 7, which are required for binding of adjacent plates 6 and also the individual segments of the cables 8. All cables 8 are installed in over one line, parallel to the flow of water. This linked between a set of cables 8 forms a generally Nadolny power cable 8, in which onstein 10 in turn is welded perpendicular to the large band 11, and the band 11 is welded lap joint and perpendicular to the middle of the other long thick strip - strip 12. To the bracket 10 and the carrier 12 are welded on the sides of the bracket 10, two thick struts 13. The ends of the skid 12 is slightly curved upward, as ski socks. On the surface of the strip 11 (but not its end) is welded to the power unit 14, which is omitted thick power cable 15. The ends of the rope 15 should be closed up "eight" on setengah at the level of the bottom of the river, and the remaining free ends of the rope 15 must firmly hold to the rope 15 plate clamps 16. Here bitanga is two thick pipes 18, hammered deep into the ground. It is necessary to provide the hole in the pipe 17 for securing the cable 15 through 18 checks. The power unit 14 lap welded metal ingot is a big blank 19, opposite the small disc 20. The disc 19, block 14, a metal strip 11, a triangular bracket 10 and is welded thereto a bracket 9 together form a large anchor, which is necessary to keep near the bottom of the river all rotating gidrokoles 1.

The large anchor can be moved around the cable 15 from the shore into the river and back using two winches 21 and two winch 22. The ends of the cables of the two winches 21 tied to the brackets 23, and the bracket 23 welded to the skid 12, i.e., Azimi 16 are used for all other cables when attaching the ends of the cables to the brackets.

Small anchor is a metal ski 24. The toe of the ski 24 abruptly bent upward. This toe is welded to the bracket 25 to which is attached the tail part nadanova cable 8. On the heel of the ski 24 weld a small disc 20 and two brackets, which are sealed to the ends of the cables from 2 winches 22. The large anchor held the bottom of the power cable 15, serves to hold the whole system gidrokoles 1 near the bottom of the river due to the fact that the head part nadanova cable 8 is fixed on the top of the triangular bracket 10, which is welded to a large anchor. Similarly, the appointment of a small anchor, but the anchor holds the tail part nadanova cable 8 near the bottom of the river. For export gidrokoles 1 in the river it is necessary to enable the control system to position in the water, and if necessary to raise them to the shore, in the position "on the beach", this includes all 4 winches simultaneously: two winches 21, which can move large anchor, and two winches 22 moving a small anchor. On one side of the winch work on the coiling ropes, and the other unwinding. However, when climbing ashore, in addition to the above 4 winches, it is necessary to include more and fifth winch 26, which picks up the slack cables all shafts 2, but prior to its inclusion should conse cables of the winch 21 and 22 were located, as close as possible to the level of the bottom of the river, should provide clamping blocks 29. Each block 29 is welded to the metal plate 30, which is welded to the pipe 31. The pipe 31 is hammered before this deep in the earth.

Each gidrokoleso 1 made of fabric, and has the form 2 buckets such as excavator buckets, molded in one piece. In Fig. 2 shows the flow of water incoming to the left at the top of the window 32 gidrokolesa 1, and the output in the bottom window 33, but to the right, i.e., occurs in the pair of forces, creating in this moment of maximum torque. On lateral sides gidrokolesa 1 has four holes for 4 cables flexible shaft 2. It allows you to mount gidrokolesa 1 on the shaft 2 so that for each pair of adjacent gidrokoles 1 maximum torque will be repeated every 90 degrees rotations of the shaft 2. On the part of the flexible shaft 2, which is located inside gidrokolesa 1, be sure to wear sturdy cord bushing 34 with a smooth external surface. Against axial displacement on the shaft 2 all gidrokolesa 1 are fixed with two clamps 16 about extreme gidrokoles.

Should provide coastal wall-Bons 35, which is necessary for removal from shore floating on water different predm is also boilers 36, you need to preheat the surface of the water in large cold in that place, where the flexible shaft 2 comes into contact with the surface of the water.

If bottom hydroelectric has about ten flexible shaft 2, on the opposite side (in our case on the left) need to install another winch 37, which is slightly to align nadgorny the cable 8, pulling him to shore.

When mounting gidrokoles 1 on the shaft 2, you must provide the following: if on the same shaft 2 gidrokolesa 1 rotates clockwise, the adjacent shaft 2 all gidrokolesa 1 should rotate counterclockwise. Only in this case the whole system gidrokoles 1 will not float on the water surface and will not lie on the bottom of the river.

Bars 19 and 20 to the large and small anchors should pick up in weight so that they do not come off the flow from the bottom of the river.

All four cables coming from gidrokoles 1 to the generator 3, to be wrapped around a thin rubberized cloth or skip these cables hoses to the flexible shaft 2 looked like a single rope, and not four cables, winding themselves algae.

If for construction of bottom hydroelectric shore was steep, it should Scuderia flexible shaft with mounted on it a few gidrokoles, one end of which rotates the generator set on the banks of the river, and the other end attached to a bearing mounted on nadonna wire rope and winches with cables, characterized in that it has two bottom power cables, flexible shaft is perpendicular to the stream, and nadgorny the cable has two anchors - big and small, and the head part nadanova rope attached to the top of the triangular bracket that is welded to a large anchor, and the tail of the rope is attached to a small anchor through the bracket having the form of a bent toe skis, with locations nadanova rope from the bottom of the river at a height greater radius gidrokolesa, with large and small armature mounted for movement with the help of winches each of them corresponding to the bottom power cable for lifting on the shore of the entire system gidrokoles at their repair during the ice flow and return gidrokoles in the river.

2. Hydroelectric power plant under item 1, characterized in that it has multiple flexible shafts and the same number of generators.

3. Hydroelectric power plant under item 2, characterized in that between any two adjacent flexible shafts gidrokolesa installed packages which meet the boilers for heating in the cold part of the surface of the water near the shore, which is in contact with the flexible shaft.
