The present invention relates to the field of water transport and is intended to improve the safety locking of the courts, namely to protect the gate of the gateway from naval vessels.

Known safety devices designed to protect the gate of the shipping gateway from naval vessels, including a flexible barrier element overlying navigable span of the gateway and dampers installed on the chamber walls gateway (A.S. USSR №1079745, IPC E02C 1/10, publ. 1984).

The disadvantage of such devices is the difficulty of maneuvering the barrier element, which when installed in a navigable span special mechanism is lowered into the water below the precipitation vessels or rises gantry lift above the surface dimensions of the vessel. Such mechanisms leads to frequent failures and stop the gateway.

Known safety devices in the form of swivel frames are pivotally mounted on the walls of the gateway. Device block navigable span of the gateway and hold the ship for cheek contours (see Rudolf Kuhn, Binnen-werkehrwasserbau, Berlin. 1984, str). However, such systems are not sufficiently reliable because require maneuvering swivel frames before each entry of the vessel into the chamber, which lengthens the cycle stopabuse and requires adjustment mechanisms of turn.

One of the closest analogues we offer is trojstva to the technical essence and purpose is the safety device of the shipping gateway Pat. RU # 2425922, IPC E02C 1/00 (2006/01), publ. 2011 (ed. Kolosov M.A.) the Device selected for the prototype of the proposed solution includes a flexible covering body in the form of a chain or rope thrown over navigable span of the gateway, and the shock absorbers. System shock absorbers made in the form of rubber blocks placed on the walls of the gateway. The rubber blocks of the shock absorbers are installed in the niches placed on the horizontal areas of the walls of the chamber locks. In these niches installed rotary beams, one end of which is supported by a hinge at the end wall niches. The second end of the beam supported on the rail path through the wheel bearing and is connected to the end of the barrier body. The rubber blocks secured at one end to the vertical wall niches, while others are based in the vertical face of the rotary beams.

The disadvantage of the prototype is the lack of reliability of the device when installing it in a navigable passage in conditions of variable water levels.

The proposed device allows you to get a new one compared to the prototype of the technical result consists in increasing the reliability of the device when installing it in a navigable passage in conditions of variable water levels.

To achieve the technical result is the following set of essential features: the safety device of sudachan the rd gateway (consisting as a prototype of the flexible body, thrown over navigable span camera gateway, shock absorbers installed on the walls of the chamber locks and bars, paired with a flexible body) unlike the prototype, flexible body secured at the ends of the rods pivotally connected with the lifting rods, the latter are installed on trucks equipped with a cable system for raising and lowering the rods, thus lifting the rod in a lowered position of the barrier body to the camera gateway supported on the truck, the ends of which are mounted shock absorbers, and the top tier of these trucks are made stepwise, while the total height of the steps corresponds to the amplitude fluctuations of water levels in the chamber, and the height of each step corresponds to step permutation of the barrier body.

Comparison of the proposed device and the prototype showed that the task - increase the reliability of the device when installing it in a navigable passage in conditions of variable water levels is solved in the new set of features, which proves the conformity of the invention the patentability criteria of "novelty".

In turn, conducted an information search in the field of water transport has not identified a separate distinguishing features of the claimed invention, which allows to make a conclusion about its soo is according to the criterion of "inventive step".

The invention is illustrated by drawings, where

figure 1 is a given device schematic cross section;

figure 2 - picture of the device in longitudinal section along the axis of the gateway;

figure 3 - image of the truck in connection with the shock absorber in the plan.

The safety device consists of shock absorbers 1 and 2 trucks that are installed on rails laid on the chamber walls of the gateway. On the trolley 2 supported rod 3, the hinge associated with the lifting rods 4. Lifting rods 4 and rod 3 is a cable-and-winch system mounted on the carriage 5. Flexible protective body (rope, chain) 6 suspended from the ends of the rods 3 and are omitted from the navigation span of the gateway. Depending on the water level in the chamber flexible body 6 position 7 at high levels or position 9 at low levels, while the rod 4 is installed to the relevant stage of the trolley 2. Accordingly, the levels of the vessel 10 is in contact with the flexible body 6.

The inventive device operates as follows.

When the naval vessel on the flexible body 6 is the transfer of force through the rod 3 on the carriage 2. The damping energy of the bulk occurs in the absorber, the force of which is transmitted to the stop 11. When deformation of the shock absorber moves truck systems 2 and rod 4.

For the passage of vessel 10, after emptying ka is a career, rod 4 is removed from truck stops 2 rod 3 and raise the barrier body 6 up above the surface superstructures of the ship.

The described device developed by specialists of the Department of Hydraulic structures, structures and hydraulics of the Federal STATE budgetary educational institution of higher professional education "State University of sea and river fleet Admiral S.O. Makarov" as part of the research work. Were calculated, which showed the possibility of using the device in the sluice chambers of the canal. Moscow and waterworks of the Volga cascade. In the future it is expected to recommend the device for use on the inland waterways of the Russian Federation, which will greatly improve the safety locking vessels and at the same time to protect the gate gateways from naval vessels.

The above can conclude according to the invention, the criterion of "industrial applicability".

The safety device of the shipping gateway, consisting of a flexible body, thrown over navigable span camera gateway, shock absorbers installed on the walls of the chamber locks and bars, paired with a flexible body, wherein the flexible body is fixed at the ends of the rods pivotally connected with lifting weights while lifting bars installed on trucks equipped with cable lifting system and opus the project rods, in turn, the lifting rod in a lowered position of the barrier body to the camera gateway supported on the truck, the ends of which are mounted shock absorbers, and the top tier of these trucks are made stepwise, while the total height of the steps corresponds to the amplitude fluctuations of water levels in the chamber, and the height of each step corresponds to step permutation of the barrier body.
