Description

The invention relates to marine technology, in particular to marine underwater weapons, and is intended for mine weapons of contact trawls towed by mine defense ships.

Known signaling mines mowing contact trawl (see patent for the invention No. 2404085 according to the application No. 2009105295 from 02.16.2009). The signaling device contains an element through which the mine acts on the trawl, made in the form of a spring-loaded lever mounted on the trawling part with the possibility of rotation when pressed with a minreap sliding on the trawling part, a device for transmitting information about mowing, which includes a switch that operates when the lever is rotated , an autonomous power source connected to a contactor, and encoded signal generating apparatus powered from said source and equipped with a hydroacoustic antenna emitting a series of acoustic impulses.

The above-described detector, adopted as a prototype, allows you to obtain information about the fact of mine landings by a contact trawl and indicate the place where this landings took place.

As you know (see AA Kondratovich and GG Piyanzov. Mine action weapons. - M .: Military Publishing House, 1989, p.12, 13), the cutters used in the construction of trawls have different designs. It can be cutters with a deep cut-throat equipped with knives, or cutters made of a set of bushings with specially applied teeth, included in the minesweeper.

In the case of using bushings with teeth or in the absence of any cutting elements on the trawling part, when the minrep is rubbed by sliding along the trawling part, the signaling device selected as a prototype allows to obtain information about mine mowing with high reliability. However, when installing cutters with a deep cut-throat on the minesweeper, it becomes possible for minrepa to fall into the throat of the cutter, and it will not be cut. The reason for this can be various factors, for example, the high strength of the minrepa, damage to the cutter knives, the reduced holding force of the mine anchor, etc. In the case described above, the mine along with the anchor is towed in the trawl behind the minesweeper, which poses a great threat to the personnel and the ship when the trawl is taken aboard at the end of the trawl.

A well-known signaling device, selected as a prototype, when a mine gets stuck in a trawl, it will work according to the algorithm described in the description of the invention according to patent No. 2404085, namely, after the signaling device has passed, the minrep gets into the mouth of the torch. After some time, determined approximately by the formula: t = l / v, where l is the distance to the next torch mounted on the minesweeper, v is the towing speed of the trawl, minrep should meet the following signaling device. If the signal from this second signaling device does not arrive on the towing ship, then this means that the minrep was cut by the first cutter, but could also get stuck in it. The information received will be perceived as confirmation of the fact that the minrep was cut, but in the case of a minrep stuck in the trawl cutter this will not be true.

The lack of information about cutting or getting minrep in the trawl is a disadvantage of the signaling device selected as a prototype.

The aim of the present invention is to increase the reliability of information about the fact of cutting minrep with a contact trawl.

This goal is achieved by the fact that in the known signaling device mines contact trawl containing a spring-loaded lever mounted with the possibility of rotation when pressed by sliding on the trawling part of the minesweeper, a device for transmitting information about mowing, including a switch that operates when the lever is turned, an autonomous source power supply connected to the contactor, and coded signal generating apparatus powered from said power supply and equipped with hydroacoustic antenna emitting series of acoustic pulses, and a spring-loaded lever zatralivanii information transmission device mounted on the cutter housing, wherein the pivot axis of the lever is mounted so as to prevent rotation of the lever in the opposite direction when the minrepa in throat cutter.

With this embodiment, the minesweeper signaling device by the contact trawl provides an increase in the reliability of information about the fact of cutting minrep.

An example of the design of the proposed signaling device is shown in figure 1 is a top view, figure 2 shows a diagram of a device for transmitting information about jamming into the equipment of a towing ship, figure 3 is an exemplary diagram of this equipment and figure 4 shows the position of the signaling device when located Minrepa in the throat of the cutter.

The alarm device contains a spring-loaded lever 1 mounted on the torch body 2 with the possibility of rotation around the axis 3 when pressed with a minreap 5 sliding along the minesweeper 4. The lever 1 is connected to the body 6, inside which there is a device for transmitting information about cutting minrepa or getting stuck in it pharynx cutter into the equipment of the towing vehicle. The specified device contains a contactor 7 (see Fig. 2), an autonomous power supply 8 connected to it (for example, a direct current battery), a timer 9, to which a controller 10 is connected, codes equipment 11, and a power amplifier 12. An antenna is connected to a power amplifier 13.

The equipment of the towing vehicle includes a receiving hydroacoustic antenna 14 connected in series, a signal amplifier 15, an analyzer 16, a code decoder 17, a recording device 18, an alarm device 19, and status indicators 20.

The operation of the proposed detector is as follows. Minrepack 5 of the mines buried comes into contact with the trawling part 4 of the contact trawl and slides along the trawling part, presses the lever 1 and causes it to rotate around axis 3. When the lever 1 is turned, the contactor 7 is activated, the battery 8 is supplied with power through the timer 9 to the signaling device - a controller 10, which generates an encoded signal through the equipment of the sending code 11 and the power amplifier 12 to the emitting acoustic antenna 13. The antenna 13 emits a signal in the form of a series of acoustic pulses in the direction of the towing ship. The signal code contains information about the location of the detector (torch) on the minesweeper, which allows you to determine the location of the mines.

The receiving hydroacoustic antenna 14, towed separately from the trawl by a towing ship on a cable cable at a given recess, receives the emitted signal and transmits it via a cable cable to the ship. In the on-board equipment, the signal passes through the signal amplifier 15, amplifies, analyzes (in the analyzer 16), enters the code decoder 17, and then to the registration device 18. After registration, the signal enters the signaling device 19 and the status indicators 20.

As noted above, the cutters used in the construction of trawls are of various designs. When using a cutter with a pharynx cutout, in the case when the cutter cuts the minrep, the proposed detector operates in the same way as the known detector adopted as a prototype. That is, when the lever 1 is turned, the signal code 1 is formed and emitted - “jamming”. After the lever 1 is returned to its original position, a signal code 2 is formed - “undercut”. In the same case, when the minrep 5 cannot be cut, the lever 1 after rotation does not return to its original position (see figure 4), and after a while, for example 5 s (a predetermined time interval), a signal code 3 ’is generated and emitted it’s dangerous, the mine is in the trawl! ” If in the process of further towing the trawl the cutting of the minrepa occurs, then lever 1 will return to its original position and the signal “undercut” will come from the signaling device.

Thus, the proposed design of the contact trawler alarm device makes it possible to increase the reliability of information about the fact that minrep was cut by the contact trawl, and if a mine gets stuck in the trawl, the place where this jam occurred is indicated.
