S., EN, 1300189, MKI4F 03 G 3/00).The disadvantages of the known devices are limited power, low efficiency, due to the complexity and multi-stage mechanism for lifting the working of solids to convert the energy source of the motor, or tidal hydro generator in potential energy of a rigid body, including the gearbox, drum, troubleshoo system.The closest in technical essence to the claimed technical solution is the system for accumulating potential energy of a rigid body, including upper and lower drives working solid with gutters made with tilt in opposite directions, the lifting mechanism of the working of a rigid body consisting of a scissor chain with receivers to host the production of rigid bodies (balls), drive scissor chains, providing its movement and delivery of desktop solids from the bottom of the drive at the top, made in the form of a piston pump, driven by renewable energies, energy tide (see p., US, 4538415, MKI4F 03 G 3/04).The disadvantages of the known devices are of low efficiency, the power limit,s tel to convert the energy tide in potential energy of a rigid body, includes articulated chain with receivers for workers solids, drive scissor circuit in the form of a piston pump unit.The technical result of the claimed technical solution is to increase the efficiency, expanding power range of devices for accumulating potential energy of a rigid body using the energy of the tides of the seas and oceans while simplifying the structure and reducing the cost of energy.The technical result is achieved in that a device for accumulating potential energy of a rigid body, including the lifting mechanism of the working of a rigid body with a source of energy in the form of energy of the tides of the seas and oceans, working a solid body, the upper and lower drives working solid with gutters made with tilt in opposite directions, the lifting mechanism of the working of a solid body made in the form of camera to host the production of a rigid body, freely communicating with the sea or ocean, while working a solid body made with positive buoyancy (<1).Analysis of the claimed device and the prototype allowed us to establish distinctive features of the prototype signs, La, freely communicating with the sea or ocean, while working a solid body made with positive buoyancy (<1), so the claimed technical solution meets the criteria of the invention of "NOVELTY."In the prior art unknown devices that convert the kinetic energy of the tides of the seas and oceans in potential energy of the working of a rigid body with maximum efficiency and availability of large masses of solids, that is, devices with large capacity, with a maximum simplification of the structure, namely the camera, directly soamsawali with the waters of a sea or ocean partially filled by workers solids, in which tidal energy is converted into potential energy of a rigid body without intermediate transformations, i.e. without losses.Therefore, the claimed technical solution meets the criterion of "INVENTIVE step".Performing a simple device structures in the camera view, partially filled with work solid with positive buoyancy allows lossless, that is, with high efficiency, to convert the kinetic energy of the tides in the potential energy of the raised solid.
In addition, the claimed device can be used in areas of existing hydroelectric or pumped storage power plants using water resources for the implementation of the artificial "tides" and "ebb".All of the above proves that the claimed technical solution will be used in industry and therefore meets the criterion of "INDUSTRIAL APPLICABILITY".The device consists of a chamber 1, installed in the waters of the sea or ocean and is provided with holes (not shown) to fill it with water 2 during high tide, the top of the chute 3 and the lower chute 4 drives made with a slope in opposite directions. Camera 1 is partially filled with work solid 5 with positive buoyancy (<1), for example, in the form of balls. The number of workers solids 5, placed in the camera 1 and camera 1 are calculated in a known manner depending on the capacity of the manufactured device and the period of high tide and low tide. Camera 1 is located, for example, (as shown in the drawing) combined with location for geodynamical, for crushing material with the use of energy raised workers solids (not shown).The device operates as follows.At low tide the working of a rigid body 5, for example, balls, committed work, from the bottom of the trench 4 of the hopper into the chamber 1, while the water level is low mark. During high tide the water 2 into the chamber 1, and the working of a rigid body 5, for example, balls with a positive buoyancy with water 2 raised to the higher water level. The upper trough 3 drive at high tide is lowered and the inner wall of the chamber 1. After graduating from high tide, the groove 3 of the drive rises and secured with a slope in it at low tide are working solid 5, which, having performed the work, the down chute 4 drives. The cycle repeats.In the inventive device the energy tide is used for lifting the working of solids 5 to the upper water mark 2, they accumulated potential energy, which is later used to generate electricity or perform other work.

SUBSTANCE: invention relates to small power engineering for transforming the flow of rivers and tides into angular kinetic energy on free-flow link hydroelectric power plants. The hydro-turbine consists of a hollow carrying shaft-cylinder with adjustable ballast, which makes it possible for the hydro-turbine to be fully submerged into water or bring it to the surface. On the shaft-cylinder are placed semi-cylinder arms, to whose ends are attached annular containers with ballast, which ensure neutral buoyancy of the hydro-turbine. On the shaft-cylinder are mounted equally along its length several discs or flat cylinders with grooves on the rims, to which are attached arms. Arms have the shape of the lateral sides of the hollow cylinder, cut-off longitudinally, thus, so that the discs are inscribed on the inner ends of the arms. A central hole is formed between the discs, of the surface carrying shaft-cylinder and the inner ends of the arms, through which communicate all vane spaces. As a result the flow goes through the entire turbine, touching the arms, which are located on the rear from the flow of the turbine end. The outer ends of the arms are tightened by rings-hoops and will form a multibladed cylinder, whose base is fully closed with the containers of ballast, tightly joined with the ends of the arms and hollow carrying shaft-cylinder.

The operating blades are bent relative to each other and provided with hinge in the point of bending. They are installed on the external side of endless band along the whole its length. The stabilisers are installed on drum shafts outside the body boards. The said stabilisers pull down endless band with blades with regard to the body bottom to activate part of the blades in the upper part of endless band during high-tide. Alternatively, the stabilisers lift the endless band to activate part of the blades in the lower part of the endless band during low-tide. There are vertical slots made in the body to adjust height of lifting or pulling down.
