Description

The invention relates to the field of marine technology and is intended to detect, determine the location and classification of submarines and surface ships, can be thrown into the sea by plane and "overboard" from ships. The sonar detection device assumes the operating position, deploys the transmitter and lowers the sonar module on the cable to a predetermined depth.

In passive mode, hydrophones capture the sound energy generated by ships and submarines and transmit information about the bearing and / or signature of the sound source. There may be directional and / or omnidirectional hydrophones. Omni-directional hydrophones detect and transmit information about a specific frequency band. They cannot determine the bearing of the contact, roughly speaking, they only indicate that they see something. They have a short detection range, so they are mainly used for detecting submarines.

In active mode, the device emits acoustic impulses in the water. By analyzing the reflected pulse, you can set the exact distance to the target.

Various types of such devices are known, for example, an autonomous pop-up buoy SU 637298 from 1977, an autonomous positioning station - RU 2096247 from 1994, and also an autonomous pop-up buoy - RU 2025395 from 06.15.92, which is closest in technical essence to the declared The invention is a sonar buoy for exploring the oceans (RU 2391245 from 2006), comprising a cylindrical body, electronic modules for measuring and recording equipment, a control unit, a drum with a buoyer, a detachable sonar module and a battery Yu, the buoy body is made of two shells inserted concentrically into one another, forming an annular and cylindrical cavity, the cylindrical cavity being connected to the overboard medium by channels, and the battery is assembled from lithium cells, installed in the annular cavity and separated from the outer shell by an air gap.

A common drawback of these devices is that they are used as on-board power sources for batteries with a finite operating time. The specific energy consumption of traditional rechargeable batteries is insufficient and requires the search and application of new energy sources with higher energy characteristics. During long-term operation, a change in the location of the devices occurs, drift by the wind and / or current, which makes ineffective the operation of both each device individually and the constructed hydroacoustic barriers.

The objective of the invention is to provide a device capable of independently replenishing the supply of electricity and maintaining its location regardless of external factors, to adjust the location and exchange information through satellite communication systems and global positioning GPS / GLONASS.

The required technical result is achieved by the fact that a housing is used, having the form of a compressed sphere, in which a water-jet propulsion is located representing a water pump operating under water. At the bottom of the bottom there is a hole through which water enters the watercourse (which is a curved pipe), in which there is a screw, the pump forces the water out through the outlet openings located around the perimeter of the casing and connected by the control unit, tells the device the force that moves it in a given direction. The upper case is covered with a thin film on a fabric basis, which is a silicon solar battery, covered with a protective layer from the effects of sea water and other weather factors, a space communication module has been introduced to transmit information about the detection of surface-underwater objects to the command post and obtain information to adjust its own location regarding the data of the GPS / GLONASS global positioning system and / or changes in the operating mode of the device.

The invention is illustrated in the drawing, which shows a device for sonar detection, including:

1 - antenna of communication and navigation modules

2 - case

3 - outlet

4 - drum

5 - Buyre

6 - detachable sonar module.

The invention works as follows. When staged both from an airplane and from a ship, the device is brought into working condition. If during the installation the device turned upside down and did not assume the initial position for operation, then when lowering the hydroacoustic module executed by the command of the control unit, the center of gravity of the device is significantly shifted down, which will inevitably bring the device to its working position. The lowering depth of the module is selected in accordance with the depth and hydrology in a given section of the sea and can be changed according to the program or at the command of a command post. When exposed to sunlight, the solar battery begins to generate electricity, sending it to consumers or replenishing the battery. The positioning unit will determine the location of the device and, if necessary, will inform the control unit of the discrepancy between the true coordinates and the set. The computing device of the control unit will develop the necessary solutions for changing the position of the device and give out control actions, start the water jet propulsion device and open the corresponding outlet openings for moving the device to a given point, which is especially important when setting up several devices and building sonar barriers.

If an underwater or surface object is detected by the measuring and recording equipment module, the signature and bearing of the sound source are analyzed, according to the results of which the object is classified, and this information is transmitted to the command post through the communication module.

Due to the ability to maneuver, the device can be at a given point for a long time, despite the hydrometeorological effects, or change its location according to a program or command received by means of communication. The operating time of the device is limited by the wear resistance of the modules and devices included in it, the temporary capabilities of the solar battery to generate electricity, which is incomparably longer than existing tools that use non-rechargeable sources of electricity.

If it is impossible to replenish depleted power sources (dark time of day, ice conditions, etc.), the device goes into standby mode. Changing conditions, replenishing power supplies, puts the device in a working position with the fulfillment of its functions in full.

The proposed invention will effectively, over a long period of time, detect, locate, classify, i.e. give target designation for the destruction of enemy submarines and surface ships throughout the entire ocean.
