Description

The claimed utility model relates to the field of repair and other works on hydraulic structures, such as offshore oil and gas rigs, piers, trestles, walls of the outlet channels, dams, bulls, bridge supports, abutments and other objects with surfaces in contact with water, with the aim of their cleaning, repair and protection against corrosion and fouling.

The prior art there are many devices that are designed to enable repair work of hydraulic structures in the areas of their interaction with water. The main features of such devices are: a housing made in the form of a hollow box with two adjacent open faces, fasteners to a hydraulic structure, means for pumping water out of the housing, means for sealing the contact zone between the device and the hydraulic structure. In the process of repair, the casing is transported by ground means to the repair site, after which it is fixed using fasteners to the hydraulic structure, then water is pumped out of the housing and, if necessary, an additional seal is made of the contact point of the device with the hydraulic structure, after which the necessary repair work in the drained capacity of the device.

The prior art device for repair work on a hydraulic structure, characterized in that on the hydraulic structure using a threaded connection, an U-shaped frame with a sealant is additionally fixed, while the housing is fixed to the frame using a threaded connection [Patent RU No. 22252292, IPC ЕВВ 1/00, priority date 03/31/2003, publication date 09/27/2004].

The prior art device for repair work on a hydraulic structure, characterized in that the hydraulic structure is additionally fixed to the template frame, and the housing is mounted on the frame using movable brackets, the device is also equipped with two ballast compartments [Patent RU No. 2098546, IPC E02B 1/00, priority date 11/08/1995, publication date 10/12/1997].

The closest technical solution is a device for repair work on a hydraulic structure, which contains a housing made in the form of a hollow duct with two adjacent open faces, one of which is equipped with a seal, ballast compartments, water pumping means, inclined articulated to the upper part of the housing rods and fasteners [Patent RU No. 157064, IPC ЕВВ 1/00, priority date 05/20/2015, publication date 11/20/2015].

The disadvantage of the above solutions is that the fastening is done both in the upper part of the case and in the lower side parts, which are located under water, while it is necessary to attract divers to install the fastening elements in the lower side parts, which significantly increases the complexity and duration of the installation process of the device to the hydraulic structure. This also complicates the process of moving the device from one repaired area to another, since for this it is necessary to disconnect the device from the fastening elements both in the upper part and in the lower side parts, and this significantly increases the time spent on repair work and increases them labor input. However, the above solutions do not reveal any means that provide a quick and easy way to move the device from one repaired area to another.

The technical task of the claimed utility model is to simplify the process and reduce the complexity of installation and relocation of the device for repair work on the hydraulic structure from one repaired area to another.

The technical result is the elimination of the need to attract divers to install the device on a hydraulic structure, as well as the elimination of the need to use ground cranes and other overall means to move the device from one repaired area to another.

The technical result is achieved due to the fact that the ballast compartments are made in the form of pontoons and are installed in the upper part of the rear and side external faces of the housing.

The essence of the claimed utility model is as follows.

A device for carrying out repair work on a hydraulic structure comprises a housing made in the form of a hollow duct with two adjacent open faces, one of which is equipped with a seal, ballast compartments, water pumping means, hinge fasteners in the upper part of the housing. Unlike the prototype, the ballast compartments are made in the form of pontoons located in the upper part of the rear and lateral external faces of the body.

The case is a hollow box, two adjacent faces of which are open. Inside the case may contain a ladder. The housing may be made of any known materials having sufficient strength, for example steel or impact resistant polymers.

Pontoons are located on the closed faces of the hull. Their number and size may vary depending on the size of the device itself, with the internal total volume of the pontoons being approximately 30-50% of the internal volume of the hull. The connection of the pontoons with the body can be made both detachable and one-piece. The buoyancy of the device is controlled by filling the pontoons with water or air. As means for supplying water, various valves or gates can be used, and they can be connected to water pumping devices designed to drain the housing. It is also possible to use an air compressor to supply or bleed air. Thus, it is possible to use various means to regulate the buoyancy of the device for repair work on the hydraulic structure.

On pontoons, a technological platform with a guard rail can be additionally located.

The fastening elements can be made in the form of brackets. The brackets can be fixed to the surface of the hydraulic structure being repaired using anchor bolts. The brackets can be attached to the device using a detachable or one-piece connection. The brackets of the repaired hydraulic structure and device are interconnected pivotally.

The sealant is fixed along the contour of the open face of the casing and is designed to prevent water from flowing into the casing capacity during work. The sealant is a sleeve made of a waterproof material with a filler, which can be used as a material with sufficient elasticity, such as cotton wool, polyurethane foam, as well as gas or air held under pressure. The sealant should be pressed as close as possible to the contour of the open face of the body to prevent the material of the sleeve of the seal from being pressed into the body contour. The seal can be fixed by known methods, for example using ropes or clamps, eyelets, eyes.

The water pumping means may be located in the lower part of the housing. It is intended for pumping water from the tank body before starting work. Moreover, this tool can also be connected to the pontoons.

The inventive utility model has new significant distinguishing features, which are that the ballast compartments are made in the form of pontoons located in the upper part of the rear and lateral external faces. During installation, the device for repair work is attached to the hydraulic structure only with the help of hinged fastening elements located in the upper part of the device. Additional pressing of the lower part is provided by pontoons filled with water, which eliminates the need for fastening the device to the hydraulic structure in the lower side parts, thereby eliminating the need to attract divers for mounting the device. Moving the device from one repaired area to another is carried out using a small floating facility. The buoyancy of the device is provided by pontoons filled with air, which eliminates the need for the use of ground cranes and other dimensional means of transportation, which reduces the complexity of moving the device from one repaired area to another. Due to the implementation of the ballast compartments in the form of pontoons located in the upper part of the rear and lateral external faces of the device body for repairing hydraulic structures, a technical result is achieved that eliminates the need to attract divers to mount the device on the hydraulic device, as well as eliminating the need for use ground cranes and other overall means for moving the device from one repaired area to another.
