Description

The invention relates to the field of shipbuilding and relates to the creation of tools capable of assisting the personnel of an emergency submarine (pl) lying on the ground under ice at various depths.

Famous rescue bell - rescue chamber of Macken [1]. The Macken rescue chamber is a robust cylindrical structure, lowered on a cable from the side of a rescue vessel. Inside the bell is divided by a bulkhead with a hatch into two parts. In the upper part are the operators controlling the bell, as well as the rescued. There is also an access hatch and immersion and ascent mechanisms. A suction chamber is located in the lower part of the bell, and a winch is installed to pull it to the emergency pl, lying on the ground, behind the running cable released from the pl using a buoy view or an emergency buoy or wound up on the pl using divers. The design of the bell provides rescue operations at depths of up to 90 meters. The technology of use involves the exact placement of a rescue vessel over the emergency plaque onto raid equipment, the divers connecting the running cable to the bell winch, pulling the bell to the hull of the plaza.

The disadvantages of this rescue bell are:

- the design of the housing made of steel, limiting the immersion depth of 90 m, which in modern conditions is insufficient;

- the need for accurate placement of the carrier vessel over the plaque onto raid equipment to ensure that the bell is docked with the emergency plaque, which is impossible in ice conditions;

- the need to lower the divers under water to connect the running cable to the bell winch;

- docking the bell with the emergency pl only with a winch and cable, which complicates the design of the bell and the technology of its use, and also increases the likelihood of tangling the cable when winding the winch, which may affect the safety of work.

This rescue bell - the Macken rescue chamber with the indicated drawbacks, does not provide rescue for emergency crews lying on the ground under ice.

Famous rescue bell SK-59 [2]. Case SK-59 steel. SK-59 is a vertical cylinder divided by a horizontal bulkhead into two parts, ensuring the salvage of the emergency crew from a depth of 250 m. The mechanisms and two operators are located in the upper part of the hull, and the pre-chamber and replacement tank are in the lower part. In the antechamber, a winch is placed for pulling to the emergency pl, lying on the ground. The rescue bell SK-59 is equipped with compressed air, electricity and telephone communications systems. However, the presence of a winch designed to ensure docking with the emergency squad, and the need to place the carrier vessel above the emergency squad on raid equipment does not allow the use of this bell when rescuing the crew of the emergency squad from under ice.

Known rescue bell SK-64 (prototype of the invention) [3], capable of operating at a depth of up to 500 m, having a compartment for accommodating rescuers and operators, a suction chamber with a docking flange for suctioning, a replacement tank to replace the weight of the rescued, a buoyancy tank, a winch with a cable for docking with the emergency pl, a battery providing two flights to the maximum depth, a periscope for monitoring the docking of the bell with the emergency pl, compressed air cylinders, soundproofing station , Water and air system. However, the drawbacks of this SC, namely: the limited supply of electricity in the battery and the field of view in the periscope, as well as the need to use an inhabited or uninhabited working device to secure the cable to the emergency pl, which also requires accurate installation of the carrier vessel over the pl, do not allow use the bell when rescuing submariners from an emergency pl under ice.

The objective of the invention is to enable the rescue bell to perform actions to rescue personnel of the emergency pl, lying on the ground under ice, and to increase their safety.

The solution to the problem is provided by the fact that in the well-known rescue bell, which has a rescue compartment for accommodating two operators and the rescued, a suction chamber with a docking flange for suctioning, a replacement tank to replace the weight of the rescued, a buoyancy tank, soundproofing station, the body is made of titanium alloy in the shape of the ball in which the direction indicator, television equipment, the sonar are all-round, and the thrusters are installed outside in the form of submersible rotary ele motors, a load-bearing electric cable, underwater lights and a manipulative pull-up device for pulling to the emergency pl and securing it to the coaming site.

New distinctive features of the proposed self-propelled telecontrolled rescue bell are:

- a body made in the shape of a ball;

- case material - titanium alloy;

- the presence of the heading indicator, television equipment, sonar circular visibility, placed in the housing;

- the availability of thrusters in the form of submersible rotary electric motors, a load-carrying electric cable for underwater lights and a manipulative lifting device located outside the housing.

These distinctive features ensure the effectiveness of the rescue operations of the self-propelled tele-controlled rescue bell to assist emergency personnel lying on the ground under the ice, and increase their safety.

In FIG. 1 is a longitudinal sectional view of a self-propelled telecontrolled rescue bell.

In FIG. Figure 2 shows a model for using a self-propelled, telecontrolled rescue bell.

Self-propelled remote-controlled rescue bell 1 has a body in the shape of a ball made of titanium alloy, a rescue compartment for accommodating two operators and rescuers, a suction chamber with a docking flange 5 for suctioning, ballast tanks to replace the weight of the rescued, a soundwater communication station, direction indicator, television equipment, sonar all-round visor, thrusters in the form of submersible rotary electric motors 2, a load-bearing electric cable 3, through which a self-propelled remote-controlled rescue olokol receives electrical power and control signals from the surface unit 10 placed on the carrier vessel, underwater lamps 4 and firming the handling device 6 for fastening at the coaming-site and to pull the emergency submarine 8.

Works self-propelled remote-controlled rescue bell as follows.

The carrier ship of the self-propelled telecontrolled rescue bell 7 moves along the ice field 9 to the scene of accident 8, lying on the ground under the ice, alone or accompanied by an icebreaker. Approaching the required distance, it becomes a course against the drift of ice. Self-propelled remote-controlled rescue bell 1 with operators inside the rescue compartment is immersed in water, the immersion and movement of the bell are controlled from the surface module 10 located on the carrier vessel. A self-propelled, remote-controlled rescue bell approaches with the help of thrusters 2 to emergency pl 8, lying on the ground, and lands on the coaming area of pl. The direction of movement is determined by the direction indicator, the radar station of the all-round visibility and television equipment mounted on a self-propelled telecontrol rescue bell. Communication with the carrier vessel is supported by communication devices built into the television equipment, which is installed outside and inside the bell to transmit video information to the carrier vessel. Fastening on the coaming site of the emergency pl is carried out using the manipulative lifting device 6, after which there is a suction.

Operators open the access hatch, help rescued submariners settle in the rescue compartment of the bell. Water from the ballast tanks of the bell is gravity drained into the hold of the ship in an amount equal to the weight of the rescued submariners, after which the operators close the access hatch, the bell is undocked from the ship and lifted onto the carrier ship.

The operation to rescue the personnel of the emergency pl can be carried out practically without interruptions, since electricity is supplied to the self-propelled telecontrol rescue bell continuously via a load-bearing electric cable.

The advantage of the proposed self-propelled telecontrolled rescue bell compared to the prototype [3], is to provide the ability to perform rescue operations to assist the emergency squad personnel lying on the ground under the ice and increase their safety.

The proposed self-propelled telecontrolled rescue bell is at the development stage of a technical proposal.
