DESCRIPTION OF THE INVENTION

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

The closest analogue of the present invention is a bottom hydropower plant comprising a flexible shaft with several hydro-wheels mounted on it, one end of which is rotated by an electric generator mounted on the bank of the river, and the other end is attached to a bearing fixed on the overhead cable and winches with cables (RU 94024157 A1, August 20, 1996).

The disadvantage of this known bottom hydroelectric power plant lies in its inefficient and unstable operation, which is caused by the unstable position of the flexible shaft with hydro-wheels in the flow of moving water.

The object of the present invention is to increase the efficiency and instability of the operation of the bottom hydroelectric power station by stabilizing the position of the flexible shaft with hydro-wheels in the flow of moving water.

The solution of the task is achieved by the fact that the bottom hydroelectric power station containing a flexible shaft with several hydro-wheels mounted on it, one end of which is rotated by an electric generator installed on the bank of the river, and the other end is attached to a bearing fixed on the overhead cable and winches with ropes, The invention is equipped with two bottom power cables, the flexible shaft is perpendicular to the river current and the overhead cable has two anchors: large and small, the head part of the overhead cable being attached to the top of the triangular bracket welded to the large anchor and the tail part of this cable attached to the small armature By means of a bracket in the form of a curved ski toe, with the possibility of placing a bottom cable from the bottom of the river at an altitude greater than the radius of the hydrodrive, while the large and small armatures are mounted, with the help of winches, of each of them along a corresponding bottom line for lifting all System of hydro-wheels during their repair or during the ice drift and the return of hydro-wheels to the river.

At the same time the hydroelectric power plant has several flexible shafts and the same number of electric generators.

Moreover, on any two adjacent flexible shafts of the hydrodrive are installed with the possibility of the opposite rotation of these shafts.

In addition, the hydroelectric power plant has boilers for heating in the frost a part of the water surface near the shore, which is in contact with flexible shafts.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 depicts a bottom hydroelectric power plant in plan view from the right bank of the river, in FIG. 2 is a hydrodrive, a longitudinal section in a vertical plane, FIG. 3 - the same, front view.

DONNAYA HYDROELECTRIC POWER STATION

The bottom hydroelectric power station can have dozens of hydro-wheels 1 mounted on one or several flexible shafts 2 rotated near the bottom of the river and is held by 2 anchors, one of which is large and the other small. Each shaft 2 rotates only one of its slow-moving electric generator 3. All hydro-wheels 1 are mounted on 4 cables forming a flexible shaft 2, which rotates an electric generator 3 installed on the river bank. One end of each shaft 2 is fixed to the power bearing in the building of the HPP, and the other end of it is fixed in the swivel bearing 4.

The bearing 4 is fixed by a piece of cable to the bracket 5 welded to the metal plate 6. To this same plate 6 two more brackets 7 are welded perpendicular to the bracket 5, which are needed to fix the adjacent plates 6 and the individual pieces of cables 8. To them, In a line parallel to the flow of water. This interconnected set of cables 8 forms a generally overhead power cable 8 tied to a thick bracket 9 that is welded to the top of a thick metal triangle-bracket 10. The bracket 10 is in turn welded perpendicularly to the thick strip 11 and the strip 11 is overlapped and Perpendicular to the middle of another long thick strip-strip 12. Two thick jibs are welded to the bracket 10 and the slide 12 on the sides of the bracket 10. The ends of the runner 12 are slightly curved upward, like the socks of skis. On the surface of strip 11 (but not at its end), the power block 14 is welded, to which a thick power cable is passed. 15. The ends of the cable 15 must be sealed with a "eight" on the bittens at the river bottom level, and the remaining free ends of the cable 15 must be firmly clamped to the cable 15 with plate clamps 16. Here, bitenteng is two thick pipes 18, driven deep into the ground. It is necessary to provide a hole in the pipes 17 for the cable 15 to be tightened by means of a check 18. A metal ingot is welded to the latch 14, a large billet 19 opposite the small billet 20. The bogie 19, the block 14, the metal strip 11, the triangular bracket 10 and welded to it The bracket 9 together form a large anchor, which is necessary to hold all rotating hydro-wheels near the bottom of the river 1.

A large anchor can be moved along the cable 15 from shore to river and back using two winches 21 and two winches 22. The ends of the cables of the two winches 21 are tied to the brackets 23, and the brackets 23 are welded to the shoe 12, i.e. To a large anchor. To fasten the cables to the clamps, plate clamps 16 are used here. Similar clamps 16 are used for all other cables when fixing the cable ends to the clamps.

A small anchor is a metal ski 24. The sock of the ski 24 is curved upward. To this nose is welded the bracket 25, to which the tail part of the overhead cable 8 is fixed. On the heel of the ski 24, a small blank 20 and two staples are welded, for which the ends of the cables from the two winches are closed. The large anchor held by the bottom power cable 15 serves In order to hold the entire hydro-wheel system 1 near the bottom of the river due to the fact that the head of the overhead cable 8 is fixed to the top of the triangular bracket 10 which is welded to the large anchor. Similarly, the designation of a small anchor, but only this anchor holds the tail of the overhead line 8 near the bottom of the river. For the export of hydro-wheels 1 to the river, it is necessary to turn on the control system in the "into the water" position, and if it is necessary to lift them to the shore, then to the "ashore" position, all four winches simultaneously turn on: two winches 21 that move a large anchor, And two winches 22, moving a small anchor. On one side, the winches work on winding the cables, and on the other - on unwinding. However, when climbing to the shore, in addition to the above-mentioned 4 winches, you must also include the fifth winch 26, which selects the slack of the ropes for all shafts 2, but before it is turned on, the ends of all its cables 27 with hooks 28 should be put on all the flexible shafts 2, When they approach the shore. To ensure that all the cables of the winches 21 and 22 are located as close as possible to the river bed level, the pressure blocks 29 must be provided. Each block 29 is welded to a metal plate 30 that is welded to the pipe 31. The pipe 31 is clogged first deep into the ground .

Each hydro-wheel 1 is made of cord and has the shape of two buckets, similar to buckets of an excavator, cast in one piece. In Fig. 2 shows the flow of water entering from the left into the upper window 32 of the hydro-wheel 1, and the outflow to the lower window 33, but already to the right, i.e. There is a pair of forces, creating at the given moment the maximum torque. On the side faces of the wheel 1 there are four holes for the 4 cables of the flexible shaft 2. This allows the hydro-wheels 1 to be mounted on the shaft 2 so that for each pair of adjacent hydrocols 1 the maximum torque will be repeated every 90 degrees of the shaft 2 turns. Part of the flexible shaft 2, which is located inside the hydrodrive 1, it is necessary to put on a strong cord sleeve 34 with a smooth outer surface. From axial displacement on shaft 2, all hydro-wheels 1 are fixed by two clamps 16 near the extreme hydro-wheels.

It is necessary to provide shore walls-booms 35, which are necessary for diversion from the shore of various objects floating on the water. They can be made from concrete slabs or larch logs.

It is necessary to provide for the boilers 36, which are necessary for heating the water surface in large frosts in the place where the flexible shafts 2 come into contact with the surface of the water.

If the bottom hydroelectric power station has about ten flexible shafts 2, then on the opposite bank (in our case on the left), one more winch 37 must be installed, which will slightly level the overhead cable 8, pulling it to the shore.

When installing hydro wheel 1 on shaft 2, it is necessary to provide the following: if on one shaft 2 hydro-wheels 1 rotate clockwise, then on the adjacent shaft 2 all hydro-wheels 1 should rotate counter-clockwise. Only in this case the entire system of hydro-wheels 1 will not float to the surface of the water and will not lie on the bottom of the river.

Dumplings 19 and 20 should be selected to a large and small anchorage by weight so that they do not come off the current from the bottom of the river.

All four cables coming from the hydro wheel 1 to the power generator 3 should be wrapped in a thin rubberized cloth or let these cables pass through the hoses so that the flexible shaft 2 looks like a single cable, not four ropes wrapping algae around them.

If for the construction of the bottom hydroelectric power station the shore turned out to be steep, then it must be made flat, raking the land not into the water, but from the water, higher to the shore.
