The device has a seal for tight connection to the surfaces of the hydraulic structure, as well as a device for water drainage, located directly in the working chamber (see RF patent for invention No. 2098546, IPC (6) ЕВВ 1/00, application filing date 08.11.1995, published 12/10/1997, “Device for repair of underwater parts of a hydraulic structure”).

The disadvantages of the known device is its unsuitability for the repair of surfaces having a broken configuration and protruding parts, as well as for the repair of the end parts of bulls of hydraulic structures.

A device is known for inspecting and repairing underwater parts of a hydraulic structure, in particular, its side surfaces, including a frame with working chambers and a pump unit, each working chamber having a window from the outside with a pneumatic seal around its perimeter. The device has clamps mounted on the side walls and in contact with the surfaces of the underwater parts of the hydraulic structure. The device is equipped with a storage tank, which is attached to the frame below the floor of the working chambers, and a vertical shaft, the lower part of which is connected with the storage tank, and the upper part is connected with the atmosphere, the working chambers being connected by water conduits with the storage tank, and the suction body of the pump unit is led through the shaft to storage capacity (see USSR author's certificate for the invention No. 1613520, IPC (5) Е02В 1/00, filing date 12/26/1988, published 12/15/1990, "Device for inspection and repair of underwater parts of hydraulic armament of ").

The disadvantage of this device is its unsuitability for the repair of surfaces having a broken configuration, and unsuitability for the repair of protruding and end parts of bulls of hydraulic structures.

Closest to the claimed invention is a device for the repair of underwater parts of hydraulic structures, consisting of paired piles, which includes a working chamber in the form of a waterproof prefabricated sectional frame with a supporting working platform and mounting posts to the upper part of the hydraulic structure, a system (device) for draining water from the working chamber and from the buoyancy placed around the entire perimeter of the prefabricated sectional frame made in the form of a pump (ejector).

The prefabricated sectional frame consists of the opening halves made in plan of semicircles equipped with spacers pivotally attached on one side to the semicircles to fill the gap between the piles with complete sealing of the joints between them and the sections of the prefabricated sectional frame. The prefabricated sectional frame is divided into compartments by height, and the working chamber is equipped with a removable sealing collar, repeating the shape of the piles and located below the working platform. The system (device) for draining water from the working chamber and placed around the entire perimeter of the buoyancy frame are installed in the lower compartment, and the supporting working platform is made of perforated steel for draining water into the lower compartment of the working chamber to the pump (ejector) (see RF patent for the invention No. 2079600, IPC (6) Е02В 1/00, application filing date 02.28.1995, published on 05.20.1997 “Device for repair of underwater parts of hydraulic structures”).

A disadvantage of the known device is its limited use, intended only for repairing the end parts of double piles having a rounded surface, and the inability to use it for repairing the side surfaces of hydraulic structures, as well as surfaces of hydraulic structures having a broken configuration and protruding parts.

The technical result of the claimed invention is to enable simultaneous repair of the side and end surfaces of hydraulic structures, including bulls with a broken configuration and protruding parts.

The claimed technical result is achieved by the fact that in the inventive device for the repair of hydraulic structures, including a prefabricated sectional frame with a supporting working platform and a pump, the sections of the prefabricated sectional frame are pivotally interconnected, and the joints between its sections are completely sealed, the prefabricated sectional frame is divided by the supporting working the platform in height to the upper and lower compartments, while in the lower compartment there is a pump that interacts with the water drainage system located in the prefabricated sectional frame, and sealing seals, according to the invention, the device is equipped with a rectangular frame mounted on a hydraulic structure and pivotally connected to the end side of the precast sectional frame, a pneumatic cylinder is installed on the upper compartment of each section of the precast sectional frame, interacting with the adjacent section, and the sealing seals are made pneumatic while the shape of the prefabricated sectional frame from the side facing the repaired surface, repeats the form of hyd technical structure along the line of contact with it.

Moreover, all hinge joints are equipped with stoppers for fixing sections of the precast sectional frame.

A device formed from a prefabricated sectional frame, in which sections of the frame are pivotally connected to each other, and provided with a rectangular frame, which is also pivotally connected to the end side of the prefabricated sectional frame, and a pneumatic cylinder is mounted on the rectangular frame and on the upper compartment of each section of the prefabricated sectional frame interacting with the neighboring section, allows you to deploy the device and provide access to any surfaces in need of repair: to the side and end surfaces of hydraulic of the building, covering it around the perimeter, and to simultaneously repair these surfaces.

The possibility of simultaneous repair of the side and end surfaces of hydraulic structures is achieved due to the fact that after water is pumped out, it does not enter and leak into the upper and lower compartments of the precast sectional frame due to the sealing of joints along the entire height of the sections of the precast sectional frame, and the presence of pneumatic sealing seals installed on the perimeter of the prefabricated sectional frame, and the special shape of the prefabricated sectional frame, repeating the shape of the surface to be repaired eskoy buildings along the line of contact with her.

The presence of a pneumatic cylinder in the upper compartment of each section of the prefabricated sectional frame, which interacts with the neighboring section and is connected to the control station, allows you to adjust the position of the prefabricated sectional frame with respect to the rectangular frame, and the presence of hinges for stoppers for fixing the sections of the prefabricated sectional frame allows you to fix their position relative to the frame and repaired surfaces.

There are two positions of the claimed device:

- the first position is transportation, in which sections of the prefabricated sectional frame are folded inside a rectangular frame;

- the second position is the working one, in which sections of the prefabricated sectional frame are deployed along the side and end surfaces of the bull of the hydraulic structure.

Technical solutions that coincide with the totality of the essential features of the claimed invention have not been identified, which allows us to conclude that such a condition of patentability as “novelty” is met.

The claimed essential features of the invention, predetermining the receipt of the specified technical result, do not explicitly follow from the prior art, which allows us to conclude that they meet such a patentability condition as "inventive step".

The patentability condition “industrial applicability” is confirmed by examples of a specific embodiment of a device for repairing hydraulic structures.

A device for repairing hydraulic structures can be performed in four versions:

- a right-handed device for the repair of hydraulic structures, including single bulls;

- a left-side device for the repair of hydraulic structures, including single bulls;

- a right-handed device for the repair of hydraulic structures, including twin bulls;

- a left-side device for the repair of hydraulic structures, including twin bulls.

Moreover, the device for repairing hydraulic structures, in particular single bulls, differs from the device for repairing hydraulic structures, in particular twin bulls, in that the sectional sectional frame section located on the end surface of the hydraulic structure has a different length.
