Description

The invention relates to the field of shipbuilding, in particular to the construction and operation of ice navigation vessels.

Known devices for maintaining navigable routes in the ice-free state, made in the form of flow formers supplying water from depth to surface (see L.V. Ivanov "Winter Operation of Water Transport Facilities", Moscow: Transport, 1978, p. 104, fig. 48). However, such devices have a limited coverage area and are used only near individual structures (moorings, locks, curls).

Known mobile flow generators mounted on the walls of the docks (Autost. St. USSR 385816, Cl. 63 s, 1/02. Priority 12/22/1971, Published in BI No. 26, 1973). However, the flow generators are also “attached” to the structure, namely to the sides of the dock, i.e. have a limited scope.

There are also known installations for lifting warm water to the surface by towed vessels, which ensure the creation of an ice-free shipping lane. However, such installations are difficult to operate, insufficiently efficient and maneuverable in floating ice.

The last invention is taken by us as a prototype.

The purpose of the invention is to increase the efficiency and maneuverability of the vessel to maintain navigable routes in the ice-free state.

This goal is achieved in that the installation is made in the form of a water-lifting pipeline and is mounted outside the vessel’s hull at an angle to the surface of the water, with the lower part of the water-lifting pipeline located in the bow of the vessel and the upper in the area of its stern.

The water-lifting pipeline is equipped with a rod (cable) suspension fixed on the underwater part of the vessel below the level of the ice cover of the reservoir.

Hinges are installed between the rods, the lifting pipe and the hull.

The lower part of the water-lifting pipeline is made in the form of a bell.

Each water-lifting pipeline can be equipped with an additional rod installed parallel to the water-lifting pipeline and forming a parallelogram with it.

The upper part of the water-lifting pipeline can be located inside the hull of the vessel and ends with a hole in the side in the stern of the vessel. In this case, the upper and lower parts of the water-lifting pipeline are interconnected by flanges, the upper of which is installed on the bottom of the vessel.

The power plant of the vessel is equipped with an additional water heat exchanger - engine exhaust gases and a pipeline for supplying heated water in the heat exchanger to the water-lifting pipeline.

The essence of the invention, where figure 1 shows a vessel with a lifting system in General; figure 2 is the same in plan; Fig. 3 is a suspension diagram of a water-lifting system on a ship; figure 4 - catamaran vessel in plan (option II); 5 is the same in cross section.

The vessel for maintaining navigable routes in the ice-free state consists of hull 1, where engines and a heat exchanger are installed (not shown in the drawings).

Pipes 2 are installed along the sides of the vessel. The lower end of the pipeline 2 is provided with a bell 3. The water-lifting pipeline 2 is suspended on the hull 1 using rods (ropes) 4 and hinges 5 mounted on the hull 1 below the surface of the water (ice). Between two water-lifting pipelines located on opposite sides of the vessel, a traverse 6 was laid.

The water intake 3 can be connected by cables 4, one of which is thrown over the pulley 7 and is stocked up for the drum of the winch 8 installed on the deck of the vessel 1.

Each lifting pipe 2 can be equipped with additional rods 9 and 10, and the rod 9 is installed parallel to the lifting pipe 2 and forms a parallelogram with it.

The upper part 11 of the lifting pipe 2 may be located inside the hull 1 of the vessel and ends with a hole 12 in the side in the stern of the vessel. In this case, the upper and lower parts of the water-lifting pipeline are interconnected by flanges 13, the upper of which is installed on the bottom of the vessel.

The ship’s power plant is equipped with an additional water-engine exhaust gas heat exchanger (not shown) and a pipe 14 for supplying heated water in the heat exchanger to the water-lifting pipe 2.

Device operation

To maintain the navigable route in the ice-free state, the vessel 1, moving along the water surface, lowers the water-lifting pipelines 2 with sockets 3 into the lower layers of the water, where the temperature is maintained at +2 ... + 4 ° С. When the vessel moves under pressure, water from the lower layers rises to the surface, leaving the surface in the stern area.

The rods 4 and hinges 5 provide fastening of the lifting pipe 2 on the hull 1 of the vessel (Fig.1 and 2).

Depending on the depth of the reservoir, the immersion depth of the water-lifting pipe 2 can be adjusted using ropes 4, one of which is thrown over the pulley 7 and is stocked for the drum of the winch 8 installed on the deck of the vessel 1 (Fig. 3).

To give rigidity to the design of the lifting device, it can be equipped with 4 rods 9 and 10 instead of a cable, forming a parallelogram with the lifting pipe 2 (Fig. 4).

When moving on an open water surface, the pipelines 2 rise to the hull of the vessel 1, and the movement of the latter occurs in normal mode.

To give rigidity to the design of the lifting device in ice navigation, the upper part 11 of the lifting pipe 2 can be located inside the hull 1 of the vessel and ends with a hole 12 in the side in the stern of the vessel. In this case, the upper and lower parts of the water-lifting pipeline are interconnected by flanges 13, the upper of which is installed on the bottom of the vessel.

Even in conditions of negative ambient air temperatures, only part of the heat of the exhaust gases can be utilized for the crew needs. Therefore, the ship’s power plant can be equipped with an additional water-engine exhaust gas heat exchanger (not shown), which allows for a ship with an engine power of 3500 kW to additionally increase the heat of water raised from the depth of the reservoir by 10-20%.

The discharge of water heated in the heat exchanger into the water-lifting pipeline is carried out using the pipeline 14 (figure 5).

The proposed technical solutions ensure the achievement of the goal of the invention is to increase the efficiency and maneuverability of the vessel to maintain navigable routes in the ice-free state.
