112 The invention relates to hydraulic structures, in particular to safety devices of lock gates. The purpose of the invention is to increase reliability by reducing the loads from the lateral movement of the vessel to a flexible barrier and brake elements. Figure 1 shows the device plan; figure 2 - camera gateway, cross section; FIG. 3 shows a section of a flexible obstruction with movable elements (rubber balls) on an enlarged scale in the initial position; in Fig. 4, the same is true when loads are applied from the pile of the vessel. The sieve of the sluice gateway contains a flexible barrier 1 rope stretched across the chamber of gateway 2. The ends of the rope 1 are attached to brake elements - hydraulic shock absorbers 3, mounted on carriages 4 moving with a drive (conventionally not shown) in vertical slots 5, made in x 6 lock chamber

2. Movable elements are put on the rope - elastic balls 7, which have a diametrical through hole 8. Inside the hole 8 there is a reinforced sleeve 9, made in the form of a spiral spring. The sleeves of the elastic balls 7 are connected by flexible connections 10 to each other, while the outermost balls 7 are connected by flexible connections 11 to the rods of hydraulic shock absorbers

3. The proposed device operates as follows. The vessel 12 piles on the rope I. At the same time, the vessel 12 has a main movement along the axis of the chamber of the lock 2, which coincides with the direction P - i.e. the force exerted by the ship on the rope in the direction perpendicular to (and the beginning of the moment) the rope. In addition, the vessel 12 always has n movement in the transverse direction relative to the sluice chamber. This movement is caused both by the wind loads, and by the fact that the vessel practically cannot move strictly 5 along its length along the longitudinal axis of the lock chamber, the so-called yaw of the vessel always happens. Thus, the force P takes place - the load acting across the lock chamber, along the longitudinal axis of the rope. However, in the proposed construction, the force P decreases sharply, as the vessel's adhesion to the rope decreases. The vessel 12 is directly in contact with moving elements — rubber balls 7, worn with a gap on the rope 1. The friction of the sleeves 9 on the surface of the rope is many times less. than the force of adhesion of the bow of the vessel 12 directly to the rope 1, the gap between the rope and the elastic ball 7 can be filled with lubricant. During lateral movement of the vessel 12, its nose portion contacts the surface of the elastic balls 7, which first slide along the rope surface, and then, when the gaps between them are completely selected within the flexible connections 10 and J1, the elastic balls 7 and the sleeves 9 are in the form of coil springs sozhmuts. Thus, the load from the horizontal displacement of the vessel is perceived and damped gently without impact. Due to the connection m 10 and P, the elastic balls 7 work both in compression and in tension.
