Hydraulic unit

FIELD: engines and pumps.

SUBSTANCE: hydraulic unit contains hydro generator, working blades rotating around a horizontal axis and having a shape formed with one parabola or with a cross of two parabolas, and a shaft running inside a bar to transfer a torque to the generator. The unit is equipped with a hollow drum with supports providing its floatation ability, and with a rotary table whereon the hydro generator is assembled. Also the hydro generator has inertial wheels with massive rims secured to both sides of the drum, and the second bar. The working blades are fastened flexibly with loops to the drum and pressed to the supports by flat springs. The shaft is made flexible and runs through both rods by means of which the axis of the unit is held and directed.

EFFECT: increased efficiency of a hydro unit.

The invention relates to hydropower and for improvement of the hydraulic unit, in particular wave unit (CAA), with the working blade rotating around a horizontal axis, which profile is formed by a single parabola or the intersection of two parabolas.

Known for HAV, containing the engine, equipped with impeller with curved in cross-section blades, driven in rotation by the waves (SU 5233 And 30.04.1928).

The disadvantage of the CAA is great resistance to the blades if there is oncoming traffic on a wave.

Closest to the invention is a hydraulic unit mounted on a platform with pontoons and containing the hydrogenerator, working blades rotating around a horizontal axis, and passing inside the rod shaft for transmission of torque to the hydrogenerator (SU 1118793 And 15.10.1984).

The disadvantages of the CAA are as follows: the CAA does not provide orientation of the floating support, which placed the unit on waves; provide a dynamic change of the distance between the pontoons when changing between wave crests. All this reduces the reliability and efficiency of the unit.

The objective of the invention is to increase the efficiency of the unit by increasing the utilization rate of the waves.

The technical result is achieved by the fact that the unit containing the eat hydrogenerator, the working blade rotating around a horizontal axis, and passing inside the rod shaft for transmission of torque to the hydrogenerator, according to the invention, the blades have a profile formed by a single parabola or the intersection of two parabolas, the unit is equipped with a hollow drum stops providing its buoyancy, rotary table on which you installed the hydrogenerator, inertial wheels, fixed on both sides of the drum and having massive rims, and the second rod, the working blade movably loops attached to the drum and is pressed against the lugs of the flat springs and the shaft is flexible and passes through both the rod through which is directed the axis Assembly.

The drawing shows the CAA with a horizontal axis of rotation.

The CAA with a horizontal axis of rotation contains working blades 1, 1a, 1B, which are movably attached by hinges (not shown) to the hollow drum 5, which provides the buoyancy of the CAA. Working the blade 1 has the spokes 3 and pressed against the stop (not shown) of the flat spring 4, providing the pressing of the blade 1 to the drum 5 in a frontal resistance, which increases the efficiency of the unit. The blades 1 have a profile formed of one or the intersection of two parabolas. On the shaft 7 of the drum 5 from both sides are permanently fixed inertial wheel 6, having massive rims and employees of the La create the inertia of the shaft 8 between the parishes of the wave pulse. On the spokes 3 of the wheels 6 on the inner side of the valves (not shown), presses the flat springs 4, serving to skip the "oblique" waves on the working blade 1. The axis 7 of the drum 5 is held and guided by the rods 9, within which is a shaft 8, the transmitting torque to the hydro generator 10 mounted on the turntable 11 and with lightning receptors 12, through the cable 13 passing the lightning current to the earth, providing lightning protection. The CAA is installed at pier 2 or from a boat. Salesasia can be carried out by lifting the BAR out of the water.

The CAA works as follows.

Sea wave height of more than 0.5 m reaches the blade 1 of the CAA, creates a rotational momentum of the blade 1 along with the drum 5 and the inertial wheel 6 and through the flexible shaft 8 rotates the hydro generator 10. Athinoula wave, dropping down from the pier 2 (ship), continues to rotate the blade 1A. In the absence of backward wave blade 1B, overcoming the drag of the water and bending the flat spring 4, is pressed against the drum 5, thereby reducing drag and increasing efficiency of the unit. "Oblique" wave, reaching the side of the inertial wheel 6, opens inside the valve, pressed flat springs 4, and continues to rotate the shaft 8. The capacity factor of the wave can reach 50%. Comparative tests made on the s models with blades showed the blade 1 having a profile formed of one or the intersection of two parabolas, more than 20% efficient blades with curved in cross section other curved blades.

The unit containing the hydrogenerator, working blades rotating around a horizontal axis and having a profile formed by a single parabola or the intersection of two parabolas, and passing inside the rod shaft for transmission of torque to the hydrogenerator, the unit is equipped with a hollow drum stops providing its buoyancy, rotary table on which you installed the hydrogenerator, inertial wheels, fixed on both sides of the drum and having massive rims, and the second rod, the working blade movably loops attached to the drum and is pressed against the lugs of the flat springs and the shaft is flexible and passes through both the rod through which is directed the axis of the Assembly.
