Description

The solution relates to underwater technology and can be used in industrial fishing for pulling a line, when laying oil and gas pipes, cables, cables and underwater works for installing various devices under ice.

Known devices for pulling a line under the ice (see RF patent No. 1671218, AOIK 79/00, publ. 08.23.1991 and No. 2153254, AOIK publ. 07.27.2000). However, these devices are intended only for fishing and have a purely mechanical design.

The closest in sum of features to the proposed and selected as a prototype is a device for pulling a line under the ice (ed. Certificate of the USSR No. 578706, B63B 21/56, AOIK 75/00, publ. 07/07/1984). The device contains an underwater shell, in a sealed enclosure of which electric motors of propellers are installed, a control unit (radio unit), homing devices in the form of hydroacoustic transducers (hydrophones) installed in the nose of the projectile and connected to the control unit. The electric motors of the control unit are powered by a floating cable, which is connected to a power source located on the surface.

The disadvantages of the prototype: limited maneuverability and range, disruption of homing in the presence of large hummocks and air bubbles.

These shortcomings are addressed by the proposed solution.

The task is to create a more reliable homing device for moving under the ice in conditions of large hummocks and air bubbles on the lower edge of the ice arising from the work of divers.

EFFECT: increased maneuverability, reliability of homing and increased radius of action.

This technical result is achieved by the fact that in a device for pulling technological devices under ice containing an underwater shell, in a sealed enclosure of which electric motors of propellers are installed, a control unit, homing devices in the form of hydroacoustic transducers installed in the nose of the projectile associated with the control unit, power supply, in the first embodiment, a ballast is installed in the center of gravity of the body, movable in the direction of the bow of the projectile, connected by a cable through a micromotor s level sensor signals within the electronic control unit, whose inputs are connected to outputs of sonar transducers, and the outputs - to the inputs of the electric motors propellers; in the second version, a vertical propulsion unit is installed in the center of gravity of the housing with a drive from a signal level sensor included in the electronic control unit, the inputs of which are connected to the outputs of the hydroacoustic transducers, and the outputs are connected to the inputs of the propeller motors and the vertical propulsion unit.

Using the control unit with a signal level sensor allows you to concentrate the control of the working elements of the device in one node and more reliably manage it without disruption.

The installation of ballast is not difficult, but allows you to solve the problem of maneuverability (tilting the bow of the projectile on command from sonar transducers).

A vertical propulsion system allows the projectile to descend when approaching an obstacle. The radius of action increases due to the mobility of the projectile.

The proposed device is shown in the drawings:

In Fig.1, 2 presents option 1, and Fig.3, 4 - option 2. Fig.1 and 3 presents a side view of the device in the operating position, and Fig.2 and 4 - underwater projectile.

Two versions are proposed. The device contains an underwater projectile 1, in a sealed enclosure installed electric motors 2, 3 propellers 4, 5. In the bow of the projectile 1 mounted homing devices 6, 7 in the form of sonar transducers (hydrophones). They are connected to the electronic control unit 8.

According to option 1, a ballast 9 is installed in the center of gravity of the body in the direction of the bow of the projectile 1. The ballast 9 is connected by a cable 10 through a micromotor 11 to a gearbox with a signal level sensor 12 included in the electronic control unit 8, the inputs of which are connected to the outputs of the hydroacoustic transducers, and outputs - with the inputs of electric motors 2, 3 propellers.

Option 2 differs from option 1 in that instead of ballast, a vertical propeller 13 is installed (Fig. 3) with a drive from a signal level sensor 12, which is included in the electronic control unit, the inputs of which are connected to the outputs of the hydroacoustic transducers, and the outputs with the inputs of electric motors 2, 3 propellers 4, 5.

The proposed device operates as follows.

Before starting work, a sonar transmitter 14 is installed in the output hole 14. A floating cable 15, it is necessary to stretch it under the ice to the output hole from the drum 16 and is connected to the power source 17. If an obstacle occurs, such as a hummock 18, the signal from the hydrophones disappears and the signal level sensor 12 turns on the micromotor 11, which with the help of a cable 10 moves the ballast 9 to the bow of the projectile 1, tilts it down and the projectile goes around an obstacle. When signals from hydrophones appear, the ballast 9 returns to the center of gravity of the projectile. 1, which can carry various technological devices.

In option 2, with the same signal from hydrophones, the signal level sensor 12 turns on the drive of the vertical propulsion unit 13 and the projectile gradually descends, and when the propulsion device is turned off due to positive buoyancy, it rises up without changing its horizontal position. Moreover, compared with option 1, the internal space of the projectile is freed up, which can be used to install various devices.

The device has high performance and is much cheaper than remote-controlled underwater vehicles.
