(57) Abstract:

Multistage turbine is designed to convert the flow energy of water into electricity or other useful form of mechanical energy. The turbine includes a vertical rotatable column with fixed thereto tiers can be rotated 90oaround their axes blades. The transmitting mechanism includes driving and driven gears, the latter mounted on the shaft of the PTO. The portion of the blades of each row is in a horizontal position, and the other part - in the vertical. Turbine allows the selection of energy with high efficiency, and to provide management during operation and to reduce the dimensions. 1 C.p. f-crystals, 7 Il.

The invention relates to hydropower and can be used to convert the energy of water flow in rivers, waves, and when the tides and low tides in mechanical or electrical energy.

Known horizontal energy water systems, comprising a vertical rotatable column with fixed thereto tiers can be rotated 90oaround their axes blades and the transmitting mechanism comprising two gears, one of cooridnate, in this part of the blades of each row is in a horizontal position /in planes perpendicular to the axis of the vertical shaft/, and the other part - in vertical /in planes parallel to the axis of the vertical shaft/, see, for example, USSR author's certificate N 1677365 A1, IPC 6 F 03 B 3/00, 1991

The objective of the invention is to increase the efficiency and size reduction.

This technical result is achieved due to the fact that turbine is further provided with installed coaxially inside the column stationary axle mounted on it a circular platform, which made the two segmental slots, and the column is equipped with pins with grooves at the ends, and the blade - sleeves to fit over the studs with the possibility of free rotation, on each sleeve, the blades of the first tier fixed gear, the slider /retainer plate/ installed with the possibility of contact with the platform, and the asterisk, and each bushing subsequent tier - two sprockets, one of which is connected by a chain with a star of the first tier, in the upper part of the fixed axle overlap with the indicators of the progress of the blades, the frame with the valves /retainers progress/ and brackets with controls, and with neither the knowledge rods/ end subcatname to interact with the gears of the first tier, traps have levers-hinges /balancers/ with longitudinal slits and axle, and in the lower part of the fixed axle brackets, on which is freely mounted levers trap /P-shaped levers, one end of which is located under the trap and has a cutout for a free connection with its axle, the second is included in box made in the axis and through the valves associated with the control levers, and on the rim pinion has two conical protrusion for interacting with the detectors, with the blades to provide buoyancy is made hollow.

Coastal multistage turbine heel contains 1, 2 spikes, bearing 3, belt 4 to overlap, reinforced tab 5, coastal concrete wall 6, polovinku 7, the overlap of the supports 8, zone 9 for the rotary speaker, cone bearing 10, the rotary column 11, the ball bearing 12, a pin 13 of the first tier, the pin 14 of the second tier, Lipnik roller 23, the sleeve 24 of the second tier, the sprocket 25 of the second tier, the chain Galya 27 pinion gear 28, the driven gear 29, the shaft 30 PTO, cone bearing 31, the ball bearing 32, the Cup 33, the wall 34 of the boiler, a circular platform 35, segmental slots 36 and 37 idle and stroke, respectively, the bearing 38, the frame 39 for valves 40 and 41 idle and working strokes, respectively, the belt brackets 42, the levers 43 and 44 idle and stroke, respectively, the tapered protrusions 45 and 46, the detectors 47 and 48 idle and stroke, respectively, the spring 49 of the detector, the bearing 50, the trap 51 and 52 idle and stroke, respectively, hinges 53 and 54 traps, levers 55 and 56 of the joints, longitudinal section 57, the pins 58 and 59 trap, the belt 60 with brackets, bolt 61, the levers 62 and 63 trap, concave cut-outs 64 and 65, the window 66 in the support 3, rods 67, shut-off reflectors 68 and 69, the hinges 70, the gear 71, the housing 72 of the turbine, the bracket 73, holes 74 in the blades 16.

Multistage turbine operates as follows.

Turbine is installed, for example, on the right Bank of the river between the two concrete ledges 5 with the intention that as much as possible to move away from the shore and install the turbine in steady flow, Osvoboditel the lock valve 41 /clamp stroke/, press down the lever 44 management of the stroke, a second end with a thrust of 67, which is connected with the lever 63 of the trough 52, will go up, while the other end of the lever 63 will fall down, and the concave wall of the recess 65, connected to the pin 59 will open the trap 52 /segmental plate/ segmental slots 37 of the stroke. When you open the trap 52 of the lever 56 with a longitudinal slit 57 will rise up together with the cut-off reflector 69, which at the free end is a gear 71, which rises above the surface of the circular platform 35 and engages with the gear 19 of the runner 20 /lock platinum/.

Similar operations should be conducted from the other side of the turbine, releasing the lock of the gate 40 /clamp stroke/, i.e., push down the lever 43 control of idling, a second end, along with a corresponding thrust 67 connected to the lever 62 of the trough 51, will go up, while the other end of the lever 62 will fall down, and the concave wall of the recess 64, connected to the pin 58 will open the trap 51 /segmental plate/ segmental slots 36 idling. When you open the trap lever 51 55 with a longitudinal slit 57 will rise up together with the cut-off reflector 68, which free conceit in the way of gear runner 20 /see Fig. 1 and 5 position 1/. When the movement of the blades 16 in the free flow of the river runners 20 will ascoltate on the circular platform 35, and the gear 19 encounter the gear 71 and will begin to unfold in the segmental slots 36 and 37, a first period of rotation of the runner 20 together with the blades 16 in the range of 40-60 percent around their axes /Fig.5, item II and III/. Upon further movement of the slider 20 faces the bearing 38 /Fig. 5, item IV/ segmental slots 36 and 37 and the adjacent side lies on a circular platform 35, when this happens the rotation of the blades 16 of the first and second tiers around their axes 90o. Rotary column 11 together with the pinion 28 is rotated around its vertical axis on a support 3. Part of the rotary blades in segmental slots 36 turned and took a horizontal non-operating position, while the remaining blades in the segmental slots 37 is turned in a vertical operating position, taking pressure free flow of the river. The blade 16, coming from the neutral position in segmental slots 37, moves in a vertical operating position /stroke/ and then doing the work, and the blade 16 extending from a neutral way there is a continuous rotation of the column 11 together with the pinion 28, which transmits the rotation through the driven gear 29, shaft 30, from which the rotation can be transmitted to the electric generator or other mechanism.

The detector 48 is used to switch blades 16 of the vertical stroke in the horizontal non-operating position /idle/.

Over the segmental slot 37 detector 48 stroke contact ball bearing 50 with the first tapered protrusion 45 /not shown/, pinion 28 and feeding the signal to the interlock valve 41, a second signal when the detector 48 ball bearing 50 will come on a cone-shaped protrusion 46, it is necessary to raise the lever 44 upward, the other end of which is thrust through 67, which is connected with the lever 63 of the trough 52, falls down when it closes segmental slot 37 of the circular platform 35 trap 52. Some blades 16, having made a half-turn 180o, go into a horizontal position and the other in the upright position, taking pressure free flow of the river and doing useful work. The detector 47 will encounter a bearing 50 on the tapered protrusion 45 and will give a signal to the interlock valve 40, and the second signal when the interaction is seeking down and closes segmental slot 36 of the circular platform 35 trap 51.

Thus segmental slots 36 and 37 of the circular platform 35 are closed traps 51 and 52 and the blades 16 are in a horizontal position, i.e., the turbine is turned off and should the valves 40 and 41 to lock /lock/ traction 67.
