The invention will otnositsa to hydropower, in particular power plants.Known hydropower plants (HPP), warab is war edited mechanics A. Yu , third edition, Moscow, "Soviet encyclopedia", 1989, S. 123).For HPP requires the construction of a dam that breaks the environment, interferes with navigation, and fish spawning.Known power plant that produces electrical energy by using the energy of wind waves in the reservoir (see USSR author's certificate 1373855 A1, IPC F 03 13/12, 15.02.1988).This setting allows you to generate electrical energy without the construction of the dam, i.e., does not violate the environment, but has a complex structure and requires the presence of a reservoir of considerable depth.The objective of the invention is the production of electric energy environmentally friendly way, without a dam and combustible materials, using any renewable energy sources, such as wind, waves, waterfalls, etc., providing periodic operation of pump stations.This technical result is achieved due to the fact that hydroelectric power plant comprises two cylindrical containers and placed them in floats with a specific gravity of 0.5, and each of the floats is associated with chain transmission, passing che is with the installed bearing on the sites main wheel with an offset center of gravity with an asterisk, the tanks are interconnected by a conduit with a valve and a water pump, with the specified chain transmission of one of the floats are connected with the left shaft and the other with the right, these shafts are fastened flanges with intermediate shaft connected two clutches opposite rotation and three toothed gears with the secondary shaft, transmission of one-way rotation by zivotnogo engagement with the main wheel, sprocket which is connected by chain transmission and clutch with flywheel, which in turn chain transmission connected to the electric generator.In Fig. 1 shows the case hydromechanical power, and Fig. 2,3 schematically depicts a power plant at the extreme positions of floats.Hydromechanical power plant contains made of reinforced concrete two cylindrical tank (vertical pipe) left 1 and right 2 sites 3 for mounting bearings. These tanks 1 and 2 are interconnected by a conduit 4 with a valve 5 and a water pump 6. Between the tanks 1 and 2 are made of a square well of 7 sites 8 for nests bearings.For seismic resistance capacity 1 and 2 square well 7 mounted on the base and buried halfway military monolithic reinforced concrete body, in which are mounted the other parts of the plant.On the top platform 3 left and right tanks 1 and 2 on bearings 17 install the left shaft 9 and the right shaft 10 with the sprockets 11 and 12, mounted on the splines. These sprockets 11, 12 worn anchor chain 13, the ends of each anchor chain 13 is strengthened through earrings to round the float 14 having the form of a barrel, in which the welded tube 15 for the free passage of the anchor chain 13, the bottom loop of each chain 13 is attached on the rotary driven pulley 16 attached to the bottom of the tanks 1 and 2.Between the left and right tanks 1 and 2 on bearings 17 mounted intermediate shaft 18, connected with the left and right shafts 9 and 10 of the connecting flanges 19.On this intermediate shaft 18 mounted two overrunning combined clutch 20 and 22.These couplings 20 and 22 rotate in opposite directions. The first clutch 20 is rotated counterclockwise and has a clip with serrated toothing 21. The second clutch 22 is rotated clockwise, the holder of this coupling is the same with toothed gearing 23, which engages with the intermediate gear 24 which engages with another gear 25 fixed on the secondary shaft 26. At the end of the shaft 26 is fixed and the other gear is with zvocnim gearing 29, member in engagement with the main wheel 30 with a displaced center of gravity (load) 31, a main wheel 30 mounted on a shaft 32 on bearings 33 mounted on the platforms 8 well 7.On the main driving wheel 30 with a displaced center of gravity (load) 31 is fixed to the sprocket 34 PTO, which transmits the rotation of the chain driven sprocket 35 mounted on shafts 36, rotating on bearings. At the end of this axis 36 is fixed to the hub 37 of the overrunning clutch. The yoke 38 of this clutch mounted on the other axis 39. On the same axis 39 is fixed to the flywheel 40 with a sprocket wheel 41 PTO, transmitting the rotation of the generator circuit 42, which generates electricity.Work hydromechanical power plant is as follows.The conduit 4 is blocked by the valve 5, the left cylindrical container 1 is filled with water up to the upper point And the float 14 is afloat, too, at the highest point.In the right cylindrical container 2 pour a little water and a float 14 is located at the lowest point B afloat.The wheel 30 with a displaced center of gravity (load) 31 (about 2 tons) is forcibly set to the lowest point In the upper point G is ogenyi all parts hydromechanical power plant is ready to run (Fig. 3).When opening the valve 5 of the conduit 4 water gravity will begin to flow through the conduit 4 from the left of a cylindrical tank 1 in the right capacity 2.Left float 14, having a mass of approximately 1 t, will hang on the chain 13 because under it leaves the water circuit 13 starts to rotate the sprocket 11. Asterisk 11 will rotate the left shaft 9, by transmitting the rotation of the intermediate shaft 18. When filled with water right capacity 2 right float 14 will begin to emerge and will drive circuit 13, which will rotate the sprocket 12. This sprocket 12 will simultaneously rotate right shaft 10 in the same direction as the left shaft 9 (synchronously), for example, the float 14 weighs 1 ton, and the displacement of the float 14 two cubic meters, it is known that one cubic meter of water is approximately 1 t, so the displacement of the float 14 raises his weight 1 tons and a ton of useful thrust (Tara weighs 1 ton, and the displacement of two cubic meters).The left shaft 9 and the right shaft 10 simultaneously rotate counterclockwise intermediate shaft 18. The shaft 18 rotates the hub 20 of the combined clutch, the rollers automatically rolled in cliniview crack and jam the teeth 21, the result is a unified whole. The teeth 21 rotate the gear 27 mounted on the secondary shaft 26.m 29 engages with the main wheel 30, rotating counterclockwise, the load 31 is lifted from the lower point To upper point G, while the output shaft 26 rotates the gear 25 fixed on him. The gear 25 rotates the intermediate gear 24. The intermediate gear 24 rotates the gearing 23, the balls roll out of klinovoi cracks and slippage occurs overrunning clutch 22.The clutch 22 is rotated counterclockwise, the teeth 23 slips and rotates clockwise (automatically rasklinivanie, and hence the slip gear 23).All mechanisms slowly rotate without interruption, cargo 31 of the main wheel 30 passes the dead point G and under the force of the weight of the displaced center of gravity (cargo) 31 of the wheel 30 begins to spin rapidly.The yoke 29 unlinked to the hub 28 and the load 31 is free to fall down (like a Bicycle wheel that begins to roll with slides, pedal and wheel raceplane bike freewheel). The wheel 30 has a diameter of about 8 m, the radius of 4 m, the load about 1.5 tons (approximately 1500 kg) lever 4 m 15004= 6000 kg received on the shaft 32. The sprocket 34 PTO transmits the rotation of the chain driven sprocket 35, rotating stand cliniview crack sticking the clip 38 and rotates on the axis 39 of the flywheel 40.The flywheel 40, receiving approximately 5500 kg pulsed rotation of the main wheel 30 will be on inertia to spin 10 min with a speed of 120 rpm and rotate the sprocket 41 and chain transmission generator 42 about 10 minutes For 10 min, the mechanical system of the hydromechanical power, working in sync with all mechanisms will scroll wheel 30 and the load 31 will move from point b to point D, namely, cargo 31, falling down, gives energy to the flywheel 40 and, after the lower point, a little bit goes up, lose energy and a fraction of a second will freeze, and the flywheel 40, having energy, will continue to spin on the axis 39 on which is mounted the yoke 38. The yoke 38 will succeed and roll the rollers of klinovoi cracks, unhook from the hub 37 and will give the opportunity to rotate freely axis 39 on which is mounted a flywheel 40.The flywheel 40 is also inertia will rotate until you have used up the energy. The load 31 of the wheel 30 will use up energy, a fraction of a second will hang at the top, as the pendulum will begin to fall back (turning zamochnoe toothing 29 of the coupling 28). But as the gears revolve continuously, the hub will Vitit rollers in cliniview gap, the rollers will jam the clutch 28, such a mechanism ka is The above procedure of work of all mechanisms will be repeated endlessly as the water in the tanks is pumped by water pump 6 from the time when the water in the tanks 1 and 2 are equalized. The pump 6 is activated in advance for a few inches before full alignment, in order to maintain synchronous operation.Pump 6 water will be pumped from the left tank 1 right 2 up until the left float 14 will drop to the lowest point, and the right float 14 rises to the topmost point. At the highest point of the pump 6 is switched off and the water by gravity now go freely back, now the water will escape from under the right float 14, he will begin to move downwards, and the left 14 is bottom - up, circuit 13 starts to move in the reverse direction, the sprockets 11 and 12 will also rotate in the opposite direction, i.e. clockwise (Fig. 2). The shaft right 10 and shaft left 9 will rotate clockwise synchronously to rotate the intermediate shaft 18. Now the clutch 22 will jam the rollers in cliniview crack, jam gearing 23 and begin to rotate the intermediate gear 24 in a counterclockwise direction. The intermediate gear 24, which is in mesh with the gear 25 transmits the rotation of which is fixed to the sleeve 28, as already described. The clutch 28 will Vitit rollers in cliniview slit and gets stuck zamochnoe gearing 29. This happens at the moment when the system mechanism shaft 9-10 and shaft 18 will change directions, and the secondary shaft 26 is rotated, it will rotate clockwise, regardless of what the float 14 is down and some up.The output shaft 26 rotates the gear 27 in a clockwise direction. The gear 27 is engaged with the gear 21 engages. The clutch 20 is rolling out videos from klinovoi cracks and rasklinivanie overrunning clutch 20. The overrunning clutch 20 is now in no hurry.Combined clutch 20 and 22 one left rotation, the other right rotation are mounted on a single intermediate shaft 18 to turn in the queue, when the shaft 18 changes the clockwise rotation and Vice versa, in a counterclockwise direction.The sinking of the mechanisms in the moment of change of rotation of the shaft 18 in the opposite direction to the other, and the rotation of the wheel from the bottom up comes at a time when the flywheel 40 received energy from the wheel 30 to partial loss (as long as the flywheel 40 is spinning at full strength). During this time, the mechanisms will automatically prepared and synchronously activated at the right period (cycle).
