Description

The utility model relates to the field of underwater technology, in particular, to underwater stations and devices intended for the protection of stationary marine objects.

There is a method of detecting, recognizing and displacing underwater objects from an offshore oil and gas platform according to the RF Patent for invention No. 2434245, G01D 15/04, G01S 13/04, 2011, which consists in placing on the one side the first monitored sonar line of the first sonar device with a block parametric radiation of low-frequency signals, and on the opposite side of the first monitored sonar line of the first sonar with the first unit of parametric reception of low-frequency signals s, in the detection - on exceeding the signal level above the level of interference in the recognition of - comparing the received signal with the reference signal and estimates the coordinates - range and bearing of underwater object, and also the impact on the underwater object by low-frequency signals and displacing it from a given body of water.

The disadvantages of this method include the insufficiently effective effect on a potentially dangerous object of artificial origin, which does not guarantee, for example, the removal of a large underwater vehicle from a protected object.

Numerous devices are also known for converting the kinetic energy of oceanic (including underwater) currents into mechanical rotation energy of turbines or rotors of power plants (see VA Korobkov, Ocean Energy Transformation. - L .: Sudostroenie, 1986. - 280 s).

The main disadvantage of the known solutions that impede their introduction into production is their low efficiency when used in ocean areas with low current speeds (almost all coastal areas except for straits). The location of such installations far from the coast leads to difficulties with the transportation of energy and maintenance of the power plants themselves.

There are a large number of sonar monitoring stations for underwater conditions (see Kozlov S.A., Lvov D.G. Overview of technical means of actively countering intrusions on objects of various categories // Security, reliability, information. - 2009. - No. 3-4. - S.30-35.). As a typical example of such devices, the Tral-M multi-beam sonar station can be used for detecting underwater swimmers moving in water on fins or using underwater vehicles, determining their location in a protected area and issuing alarm notifications to the technical means of security alarm.

“Tral-M” includes: observation post equipment located on the shore at the observation post and consisting of a service device for a sonar device and a display and control computer; the remote part installed in the aquatic environment on the approaches to the guarded objects, consisting of a remote hydroacoustic device including one or several antenna modules and a mounting device, a communication cable, and a cable junction box for switching several antenna modules. In this case, the required configuration of the protection zone of the remote sonar device is formed by a set of antenna modules with a viewing sector in the horizontal plane of one module of 30 degrees. The maximum number of modules is 12 (for the formation of a pie chart 360 degrees.). The GU and the mounting device are installed on the prepared site at the bottom, or with mounting on a pile or other hydraulic structures. The surface hardware can be placed both in the capital structures of security posts, and in mobile containers or van bodies.

A common drawback of these devices is the separation of systems for detecting underwater hazardous objects (sonar stations) and threat response systems (often provided by armed guard units or special forces).

The closest in design to the claimed solution is the complex described in the invention, “Method for installing the complex for underwater technical work at the bottom of the water area and its dismantling and complex for underwater technical work” according to RF Patent No. 2355598, B63B 35/44, 2009 ., containing a predominantly circular cross-section with an increasing area to the base of the body with a skirt located in the upper part of the complex housing an air bell, and the upper section of the complex housing is placed in the air (gas) environment of the bell, at the top ballast tanks (inflatable containers), a pipeline connecting the bell’s internal gas cavity with ballast tanks with a valve for opening and closing it, a drainage pump for the complex’s case, Kingston’s flooding and automated systems — a system for maintaining gas composition and pressure inside the air bell and the complex — are installed to it parts of the bell as well as the air supply system (gas medium) inside the air bell and the complex housing during its drainage, the air bell is equipped with a loading platform with a coaming area and located in the upper part of the complex with a cargo lock chamber, the air bell has a shelter (diving unit) for staff, made in the form of a baro-complex with lock chambers and rescue equipment.

The disadvantages of the known complex include the lack of protective elements that allow, if necessary, to detect a potentially dangerous object, identify it and take measures for its removal.

The inventive utility model solves the problem of increasing the effectiveness of counteraction to potentially dangerous objects, as well as reducing energy costs for this from the protected object.

The technical result is to increase the autonomy of the underwater launch platform, as well as reducing the response time to an underwater threat to the guarded object.

The solution to this problem is achieved by the fact that the design of the device contains a hollow strong body mounted vertically on the ground using a system of braces and anchors with a round skirt, using a hydraulic pump embedded in the bottom, launchers located inside or outside the body, using defense systems to push them uninhabited underwater vehicles, the electricity received from the large-capacity batteries located inside the casing, connected with an electric generator generating electricity roenergiyu installed by rotating the upper part of the turbine rotor or platform interacting with underwater currents, and also disposed within the housing and operational system for tracking an underwater environment, comprising information management apparatus and one or more antennas hydroacoustic transmitters. In this case, the underwater launch platform can be connected to the guarded object or ground control point with cables for transmitting backup electricity, information about the underwater situation and potential targets, as well as remote signals about the launch of defense uninhabited underwater vehicles.

The proposed utility model is illustrated using the drawing, which shows a side view of the complex.

The drawing shows a General view of a utility model in section, on which a strong body 1 of the platform is mounted vertically on the ground and fixed in this position using braces 2 with winches not shown in the drawing attached to the anchors 3.

In the upper part of the housing 1 there is a turbine 4, the shaft of which interacts with the electric generator 5, the energy from which is transmitted through the cable 6 and accumulated in the batteries 7. Inside the housing 1, launchers 8 connected to the batteries 7 are installed, in which defense uninhabited underwater vehicles 9 are located.

The lower part of the housing 1 is made in the form of a round skirt 10, embedded in the bottom rock. On the outer part of the skirt is installed a hydraulic pump 11, connected to the inner space between the skirt 10 and the bottom.

Also inside the housing 1 is information and control equipment 12, processing information from the sonar antenna 13, as well as from a guarded object or ground control point. This information, together with the possible supply of reserve electricity to the platform, is transmitted via cables 14 laid along the bottom of the water area.

Submarine launch platform works as follows.

Before installation on the bottom, the underwater platform is fully prepared for operation for a certain period of time. In this case, the batteries 7 are charged, the installation and operation of the equipment located inside and outside the solid housing 1 are rigidly mounted and checked, as well as loading inside the launchers 8 of the underwater vehicles 9.

After transportation of the platform to the place of its installation on the bottom, divers or underwater vehicles are mounted on the ground with anchors 3. After that, a tank filled with gas, not shown in the drawing, having such a volume that the total buoyancy of the platform is not shown, is attached to the upper part of the body 1 having negative buoyancy connected to it was positive, but close to zero. After that, with the help of a cargo device, the platform is lowered from the supply vessel into the water, and stays afloat close to the surface of the water. Then, using divers, stretch marks 2 are attached to the platform, connected to the anchors 3.

By changing the amount of gas in the tank and working with winches, removing the slack of stretch marks 2, a controlled immersion of the platform, which is in an upright position, to the bottom is carried out.

Upon reaching the bottom, the strong body 1 is oriented using stretch marks 2 in a vertical plane, after which the hydraulic pump 11, which is powered by accumulators 7, is driven, which pumps water out of the cavity created by the internal volume of the skirt 10 and the outer surface of the bottom. At the same time, the hydrostatic pressure acts on the outer surface of the skirt 10, which contributes to its deepening into the ground and the firm installation of the platform. Installation is completed by the final alignment of the housing 1 in a vertical plane due to the tension of the stretch marks 2.

One or several launching platforms installed around the guarded object are connected to it or to the ground control point by cables 14. Upon the signal from the guarded object, the platform installed on the bottom activates the operational monitoring system for the underwater situation and starts transmitting the received information to the guarded object. At the same time, the platform’s power supply system also begins to operate - under the action of underwater currents, a turbine 4 is driven, the rotation of which with the help of an electric generator 5 is converted into electricity. A smaller part of this energy is consumed for the operation of information and control equipment 12 and a hydroacoustic antenna 13, and a large part is used for charging the batteries 7. Moreover, the total continuous charging time of the batteries (up to several months) makes it possible to compensate for the low speed of rotation of the turbine 4 due to the low speed of the underwater currents.

In the event of a threat to the protected object from any underwater objects, the operational tracking system detects them and classifies them. Moreover, the distance determined from the launch platform from the launch platform to the guarded object gives additional time for more accurate determination of the coordinates of the dangerous object and clarification of its trajectory. This, in turn, contributes to a more efficient operation of uninhabited security underwater vehicles 9.

If the object really poses a danger to the protected object, a decision is made to release one or more underwater vehicles 9 for its removal from the target. Moreover, the number of launchers 8 allows you to store on the launch platform uninhabited vehicles 9 of various types of actions - from wave (low-frequency) impact on a biological object to the impact of a shock wave (water hammer) on a technical device.

To create a pulse pushing out the uninhabited apparatus 9, the launcher 8 uses the electric energy of the battery (or several batteries) 7. In this case, the total capacity of the batteries 7 should be sufficient for at least three successive triggering of the launchers 8.

If there are many threats, and there is a need to launch a larger number of underwater vehicles 9, electricity for the operation of launchers 8 can be obtained directly from the guarded object via cable 14.

Thus, the tasks set for the proposed device are realized.
