Description of the operation of the device "installation" for the melting of ice (hummock) and the delivery of explosive (EXPLOSIVES) or gas-air mixture (GVS) and explosives (ice) under ice (hummock) or in the body (thickness) of ice (hummock) using a pyrotechnic composition (PS)

In difficult ice conditions on the northern rivers, aerial ice reconnaissance is carried out for the most difficult congestion-hazardous areas using measuring devices of ice parameters. Having determined the thickness of the ice (congestion), in the threatened areas, detonation brigades with helicopter crews (type MI - 8) are assigned to the areas.

The first embodiment of the installation (figure 1)

In difficult ice conditions and ice jams of up to 0.5 meters, the installation is installed vertically on ice (Fig. 1) using a helicopter.

The vertical position with respect to ice is achieved by four persistent (12) and four auxiliary (14) rods connected to each other by a pivotally movable mount (18), and with the body through the stops.

To bring the installation into working position, the locking elements (10) are removed.

The cargo line coming from the helicopter and the yoke (2) are interconnected via an electric lock (1) which is disconnected after the installation on ice and ignition of the pyrotechnic composition (PS) (13) with an electric igniter (type MB - 2 N) (17).

After the start of heat generation by the pyrotechnic composition (13), a fuse (such as dense foam or a thin sheet of plastic) melts (Q = 1500 C) (15) after 10-15 seconds.

In the next 10-15 minutes, the installation melts ice (congestion) at a speed of 100-120 cm / min, while the shells (11) equipped with explosives (DHW) are connected to each other and to the coil by a control safety cable with an electric line (with fixing the depth from 3 to 15 meters) (6). The function of centering the cable after the exit of the explosive (DHW) from the housing is performed by the guide (7).

The second embodiment of the installation (figure 2)

When ice jams from 0.5 meters, the installation is set for the side yoke on the ice (figure 2) using a helicopter.

The principle of operation of the installation is the same as in the first embodiment, but has a difference in the fastening of four thrust (1) and four auxiliary (2) rods through the stops (3) as shown in Figure 2. The rods in this position are used the same as in the first version.

The principle of operation of the installation (figure 3).

When in the explosive (hot water) position under ice, the initiation of short-duration industrial electric detonators (type EDKZ-25, EDKZ-PM-15) is carried out through the use of an actuator (1) from which the electric line goes to the electric detonators. The signal to the actuator (1) is supplied from the command instrument located on board the helicopter at a distance from the explosion to 3 km.
