Brake plates 6 are provided with supporting elements 7, for example rollers, which interact with the bottom surface of the raft and are intended to create additional moving support points during turns. Brake shields are placed near the stern of the raft section, taking into account the maximum required angle of rotation in the horizontal plane.

The number, size and layout of the brake shields 6 is appointed taking into account the design of the raft or its section and the nature of the waterway. 15

The hinge mechanism 5, located in the middle parallel to the short edges (along the small axis of symmetry) of the brake shield 6, serves to attach the latter to the bottom surface 20 vertically around the axis 22 and horizontal around the link 21 with the sleeve 25 movably mounted on it 20 14 planes under the action of hydrodynamic pressure of water and generated forces in the central 14 and side 16 tons 25 along

The limiting clutch 15 of the central link 14 serves to provide a predetermined or desired angle of rotation of the brake shields 6, and the throttle sleeves 17 of the side thrust 16 are designed to prevent the part of the brake shields that is rigidly attached to the shield from slipping.

Fixers-limiters 8, placed on the hydrodynamic pressure-receiving water surface of the brake shield 6, are used to create the angle of attack (attack) of it, which provides the possibility of starting to turn and hold them in the transport position.

The locking latch 23 of the link 20 of the hinge mechanism 5 serves to fasten the latter with the carrier beam 9 and can be performed, for example, in the form of a fork, bracket, arc, or combinations thereof.

The transverse carrier beam 9 with cable blocks 10 and 11 at the ends is designed to ensure that the braking force transmitted by the center cable 14 is transmitted, along the longitudinal attachment 2 of the raft and prevent its displacement, as well as creating an additional attachment of the raft.

It can be of any cross-sectional shape and from any material, for example, from wood (bags made of assortments or logs or individual logs - parabers) providing the required compressive strength and buckling.

The lever stops 13 of the carrier beam 9 serve to prevent it from twisting by distributing the load transferred to it from the braking force through the rope blocks 10 and 11 over a large support area. They can be monolithic with a carrier beam or stand-alone products of any cross-sectional shape, arranged perpendicularly or at an angle relative to the carrier beam,

The limiting clutch 15 of the central link 14 serves to provide a predetermined or desired angle of rotation of the brake boards 6, and the securing clutches 17 of the side pull 16 to prevent the part of the braking shield that is rigidly attached to the shield from slipping.

Clamps-limiters 8, placed on the hydrodynamic pressure-sensing water surface of the brake shield 6, serve to create the angle of attack (attack) of it, which makes it possible to start turning and holding them in the transport position.

After that, a tension force is created in the central 14 and lateral 16 t gax and the brake shield 6 is brought to the transport (horizontal) position, pressing them against the bottom surface of the raft sections 1 until the locking mechanism 8 stops.

During braking, the latching stops 8 are turned off, the tension in the tow ropes and the longitudinal attachment 2 of the raft is relieved, and the central 14 and side 16 cable rods are loosened (relieved), freeing the upper edges of the brake shields from bonds, under the influence of hydrodynamic pressure water, its own gravitational forces and equipment and the kinematic energy of the propulsive-I state raft rotate in a vertical plane around the axis 22 of the sharmirnaya mechanism of braking angle of rotation, at the same time perceived emuyu yE | elimivayuschuyus normal (parallel to the direction of motion of the raft) component of the hydrodynamic pressure on the brake shield 6 is yuschuyus braking force, decelerating the raft.

The maximum braking angle of rotation of the brake pads is 90 to the longitudinal axis of the raft, which is fixed by the limiting clutch 15.

Adjusting and increasing the magnitude of the braking force and distributing it along the longitudinal attachment 2 is carried out by equipping several transverse and longitudinal rows of sections 1 of the raft with brake boards 6 and a variation of the dimensions of the latter (width and height).

At the end of braking, tensions are created in the central and lateral cable rods 16, thereby turning the brake shield 6 around the axis 22 of the hinge mechanism 5 towards the bottom surface of the raft until the stop clamps 8 act.
