DESCRIPTION OF THE INVENTION

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

The closest analogue of this invention is a hydroelectric plant comprising one or more electric generators, rotating, respectively, one or more flexible shafts at the end of the armature and vane gidrovintami mounted on each flexible shaft (SU 1213237 A, 23.02.1986).

A disadvantage of this known hydroelectric it is inefficient and unstable, due to the unstable situation gidrovintami flexible shafts in a stream of moving water.

The object of the present invention is to increase efficiency and stability by stabilizing the hydroelectric flexible shafts gidrovintami stream of moving water.

This object is achieved by the fact that the hydropower plant, comprising one or several electric generators, rotating, respectively, one or more flexible shafts with an anchor at the end and paddle gidrovintami mounted on each flexible shaft, according to the invention is provided connected to the armature block, a bottom rope, the ends of which are fixed on the shore bitt, and two onshore winches gidrovinty made a twin of four wire ropes, forming a flexible shaft, which is located on the bottom of the river at a distance equal to the length of the blade gidrovinta, each generator is set on the banks of the river, and the end of each flexible shaft attached to the anchor through the triangular bracket welded to the edge, and is attached to the top of the bracket at a height from the bottom of the river, to the length of the blade gidrovinta, bearing, to which is fixed the end of a flexible shaft, the longest cable is passed through the block to move the armature with two onshore winches on bottom rope to the shore and from the shore with ice and the replacement gidrovintov on flexible shafts.

In this plane two two-blade paddles each gidrovinta perpendicular to one another.

And on any two adjacent flexible shafts gidrovinty made with the opposite rotation of the shafts.

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

The bottom of hydroelectric power plants

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows the bottom in terms of hydroelectric power at the sight of the right bank of the river, in FIG. 2 - two-blade gidrovint, side view; FIG. 3 - the same, top view.

The bottom has dozens of hydroelectric gidrovintov 1 mounted on one or more flexible shafts 2. Each flexible shaft 2 rotates only one generator 3. All gidrovinty 1 revolve around the bottom of the river, as it is held at this height from the bottom of the river by two anchors: a large anchor and small anchor. Each flexible shaft 2 consists of four wires, which are strung gidrovinty gidrovintov 1. The entire set 1 on the shaft 2 is fixed clamp plate 4. In FIG. 1 is a bottom hydroelectric two shafts 2, but it may have a greater number of shafts 2, for example 4, 6, 8, and so on. D. The head part of each of the flexible shaft 2 is fixed to the swivel-bearing 5. The bearing 5 are attached to the power brackets 6 and each bracket 6 is welded to the sheet metal to its triangular arm 7. such brackets 7 - two and both brackets 7 are welded obliquely to the long thick strip 8, and the band overlap 8 is welded to the middle of the other bands - the runners 9. The brackets 7 and 9 runner connected by welding two side skid plate 10. The ends of the struts 9, slightly bent upwards and welded thereto brackets 11 which by means of jaws 12 are mounted hoist rope ends 13. to the other long edge strips 8 welded to the power unit 14, in which the power cable 15 is omitted . The ends of the cable 15 are sealed on the shore bitt, which are two metal thick pipe 16, scored deep into the ground close to each other. Cable 15 is imposed on the tube 16, eight, and the remaining free end of the rope 15 is clamped to the front part (at the entrance to bitt) 17. Cable clamp 15 on pipes 16 Contra cotter 18. unit 14 and the band 8 heavy welded blank 19.

Lane 8 and 9 skid welded perpendicularly to each other, two arms 7, 8 are welded to the strip; the power unit 14 and ingot 19 together form a large anchor that keeps near the bottom of the river all gidrovintov system 1, strung on two shafts 2, at a height of one blade length gidrovinta 1. Lesser anchors are spherical heads 20, mounted next to the terminals 4 on flexible shafts fixed by clamps 2 and 4. Nozzles 20 may be heavy or light on the contrary, as the foam, depending on the flow rate. All nozzles 20 should be selected according to their weight, so that the tail portion of the flexible shaft 2 has the same level of the river bottom, which is part of the head and the flexible shaft 2, ie, at the height of the length of one blade gidrovinta 1. To lift the cable 15 is not over, it has to be secured on the bitt as low as possible, bringing it closer to the level of the river bed. And to bring the two rope winches 13 to the level of the bottom of the river, we need the pressure blocks 21 are installed on the banks. For each block 21 deep into the ground hammered metal pipe 21, the upper part of which is close to the level of the river bed. On top of the thick tube 22 welded to plate 23 and has welded to it the top section 21.

Bladed gidrovint 1 need to be made of solid-cast a cord having a wide solid blade 24. The planes of the two blades 24 are perpendicular to each other, ie, form with the shaft axis 25 an angle of 45 o. In the central-axis (cylindrical shape) of the shaft 25 are provided four through-holes in which four cables are passed flexible shaft 2. The four cable mount allow all gidrovinty 1 so that any two adjacent gidrovinta 1 on the shaft 2 have been displaced in the course of rotation about 90 on its axis o, and this means that any two adjacent gidrovinta 1 together form a four-bladed propeller.

When manufacturing gidrovintov 1 should provide for the difference in their structure: one half to all of the spot of bottom gidrovintov 1 hydroelectric rotated in one direction (clockwise), the other half - in the opposite direction (counterclockwise). And then any two adjacent flexible shaft 2 at the bottom of hydroelectric power will rotate in opposite directions, which will increase the efficiency of the use of the kinetic energy of moving water.

FIG. 3 shows the membrane 26 located between the bases of the blades 24 and 25 of the shaft surface gidrovinta 1. These membranes 26 strong, as are the vanes 24. They add strength and rigidity to the blades 24, do not allow them to bend under the pressure of the water flow. The front edge at the blade 24 slightly inclined towards the water course.

Flexible shafts 2 in the areas of small anchors to 3 generators need to wrap the rubber cloth or fabric instead use a hose length equal to these areas, ie, each flexible shaft 2 looked one rope, not scattered four ropes are wound on the algae.

The whole system gidrovintov 1 hydroelectric bottom can be pulled to the shore (in our case, on the left bank of the river) with the same time included two winches 13: one for winding and unwinding on the other. As the gidrovintov 1 to the bank, you have to throw on the 2 ends of the flexible shafts winch cables 27 with hooks at the ends, turn the winch 27, and it will pick up the slack of flexible shafts 2, pulling them ashore. This stretch of the shore gidrovintov 1 is necessary for replacement, but also with the icing.

For removal from the shores of floating on the water objects should be put off wall-booms 28, made of concrete or of larch logs.

In severe frosts it is necessary to heat boilers 29 from the shores of surface water, which is in contact with the flexible shaft 2. This will prevent the freezing of ice on them.

If the bottom construction of hydroelectric river would be cool, it is necessary to make a gentle, shifting the ground not in the river, and on the shore.
