The blades are separated by two axes of unequal length part. Most along the length of the part has less weight. 1 Il. The invention relates to hydropower, in particular to hydraulic turbines installed in the rivers depth up to 1 mClosest to the invention is a hydraulic turbine, containing a rotor with a horizontal shaft, blades located around the shaft and mounted to rotate on axes parallel to the shaft, and stops limiting the angle of rotation of the blades, and each blade is separated by axis into two unequal weight part.Technical results of the invention is more complete use of the energy of the river flow.This is achieved by the fact that the turbine rotor is immersed in the stream to the axis of the shaft and part of the blade with the lower weight has a length greater than the other part of the blade.The drawing shows a hydraulic turbine, a General view.Hydraulic turbine codignotto rotation on axes 3, parallel shaft 2, and the lugs 4 and 5, limiting the angle of rotation of the blades, and each blade is separated by axis into two unequal weight parts 6 and 7, the rotor is immersed in the stream to the axis of the shaft 2 and part 6 of the blade with the lower weight has a length greater than the other part 7 of this blade.Hydraulic turbine operates as follows.Case 1 hydraulic turbine immersed in the stream to the axis of the shaft 2, and the fluid acts on the blades of the turbine rotor, which rotate on axes 3 between the stops 4, performed on the shaft 2, and the lugs 5, arranged in the flow area of the turbine housing 1, completely block the flow. In this part 6 of the blades are guided in lugs 4 of the shaft 2, and at the exit of the flow vane turns on the axis 3, and exits thread part 7 having a smaller length and resistance.The blades are heavier flow part 7 almost vertically, while the blade enters the work to dive into the flow axis 3.Hydraulic turbine can be used to pump water from the river for agricultural purposes and fire fighting as well as for electricity generation. HYDRAULIC TURBINE, saterday rotor with horizontal shaft, lapastora, organizowanie the angle of rotation of the blades, and each blade is separated by axis into two unequal mass parts, characterized in that the rotor is immersed in the stream to the axis of the shaft and part of the blade with the smaller mass is longer than the other part of the blade.

Vertical shaft is arranged in well built near bank and communicating with river by channel made under level of maximum possible thickness of ice cover. Part of horizontal shaft connected with hydraulic turbine is arranged in said channel. Upper end of vertical shaft is connected with generator through ground horizontal shaft and step-up reduction unit. Stream shaper is made in form of flaps installed on shaft for turning to direct water stream of river to its central part between which turnable gate is installed for contacting with one of flaps to direct water stream to right-hand or left-hand side of hydraulic turbine.
EFFECT: provision of reliable operation all year round.

SUBSTANCE: proposed hydraulic turbine generators are designed for creating stationary and portable hydraulic plants of modular type. Generators have rotor with central shaft non-rotating around horizontal axis or vertical axis (as version) on which chain drive gears are rigidly fitted, each being coupled through independent chain drive with planet pinion members arranged radially and uniformly around central shaft. Each member has blade reduction gear consisting of gear of chain drive and of large and small cylindrical gears, the latter being coaxial and rigidly coupled with gear of chain drive of blade reduction gear, and large cylindrical gear is rigidly secured on axle of blade installed horizontally for generator (or vertically, as version). Each blade rests by ends of its axle for rotation on brackets secured on hubs by bases. Hubs are installed on both ends of shaft for rotation and tops of brackets at both ends of central shaft are connected by ring rims being drive wheels connected with energy converters by flexible drive.

Turbine hoist has rocker arm for turbine suspension hinged on one end to catamaran and on other end, to turbine frame that mounts generator-drive bevel gear so that longitudinal axes of hoist rocker-arm hinges and longitudinal axis of bevel-gear driven pinion are disposed on same line. In addition, hydroelectric power plant is equipped with device enabling variation of turbine angle of installation to water flow.

SUBSTANCE: turbine is designed to convert energy of water or air streams inflowing from side. Proposed turbine has shaft hinge-mounted in post around which blades are installed for turning in radial directions between supports rigidly and normally connected to shaft. Turning of blades is limited by stops. Blades are made flat, with rounded off long edges, and are arranged around shaft minimum in two directions with spaces between edges. Turning of blades is limited by two stops, and tire in turbine, thus formed, repeats in length of shaft with uniform angular turn. Supports can be made in form of radial cantilevers with aerodynamic profiling of cross section. Stops are made retractable into support body if pressure force of blade exceeds calibrated force of spring holding the stop in working position.
EFFECT: increased efficiency of using energy of fluid medium flow, simplified design.

SUBSTANCE: invention is designed for creating stationary and transportable modular hydraulic plants and setting up unit hydraulic power stations. Proposed water-wheel generator has body, shaft with central bevel gear, planet pinion members, each containing blade and shaft with bevel gears on ends, one end of shaft being coupled with central gear.

Shaft of each planet pinion member with bevel gears on its ends is made single-section, and bevel gear belonging to said shaft and pointed to side of blade of said planet pinion member engages with bevel secured rigidly and coaxially to smaller spur gear of blade reduction gear. Larger spur gear engages with smaller one, and it is secured on axle of blade installed vertically. Each blade rests by ends of its axle for rotation of brackets mounted by bases on cylindrical housing installed for rotation coaxially relative to central shaft, and tops of brackets at both ends of central shaft are connected by ring rims. Upper rim, being drive wheel, is coupled with energy converters. Central shaft rests by both ends with locking on framework provided with pontoon devices. Invention makes it possible to use river current energy with maximum efficiency at no adverse effect on environment caused by submersion of river flood lands caused by building of dams, energy of ocean currents, energy of tides and ebbs owing to use of blades with two points of support.
