Description of the invention

The subject of the invention is a manned floating object for underwater works, intended for all repair, rescue, exploration and other works at shallow depths.

There is a known solution, known as a bathyscaphe, in the form of a manned underwater floating object. It is a very complex self-propelled device designed to reach very great depths, mainly for research purposes. The bathyscaphe can move horizontally underwater and is not intended to be floated on the surface of the water. Very high design and technological requirements make its construction and operation very expensive. Its use for underwater works at shallow depths is economically unjustified.

It is also known as a bathisphere, a sealed spherical cabin lowered from a ship onto a rope for exploring the depths of the sea. Also in this case, the design and technological requirements are very high, so construction and operation are very expensive. Therefore, the use of the bathisphere for works at shallow depths is unprofitable.

The object of the invention is to overcome the disadvantages presented, which is achieved by the following solution. A manned watercraft for underwater work, equipped with means for displacement in the aquatic environment, has an oblong hull with an upper crew compartment and a lower, sealed, longitudinal working chamber. The working chamber has a drive unit inside for driving a rigidly mounted longitudinal lead screw inside the working chamber, which is able to move the ballast connected with it, embedded in the guides of the working chamber. At rest, the ballast with the drive unit is located in the central part of the working chamber.

The fuselage has a separating plate inside between the working compartment and the crew compartment. The working chamber is set in the hull in the shape of a tube. The lead screw is placed in the longitudinal axis of the working chamber. The ballast has a cylindrical shape, the side surface of which is mounted in guides protruding from the inner side surface of the working chamber. The control part of the power unit is located in the crew compartment area.

The solution according to the invention allows you to submerge a part of the object in a specific place and at a certain depth and to perform underwater works at shallow depths. The object in the submerged position is very stable, which makes it easier for the crew to do their work. Thanks to the use of, for example, manipulators, it is possible to perform the necessary work from the submerged part of the facility without the need for divers, whose work requires the use of time-consuming and costly decompression methods.

The solution according to the invention is shown in the embodiment in the drawings, in which fig. 1 shows a manned underwater work vessel in side view, fig. 2 - hull, in the cutout B shown in fig. 1, fig. 3 - interior of the hull, fig. a section along the line AA shown in Fig. 1.

A manned submersible object has a sealed hull 1 with a cylindrical side surface. The upper part of the fuselage 1 constitutes the manning compartment 7. The lower part of the fuselage 1, separated by a separating plate 8 from the upper part of the fuselage I, comprises a working chamber 2, also in the shape of a cylinder. The working chamber 2 has a centrally located drive unit 3 for driving the lead screw 5, mounted longitudinally in the working chamber 2 on both sides of the drive unit 3. On the drive screw 5 on both sides of the drive unit there are cylindrical ballasts 4. Depending on the needs, the ballast is moved in the rear or in the front part of the working chamber 2. The ballast 4 has two longitudinal slots on the outer cylindrical surface, embedded in the longitudinal guides 6 of the inner side wall of the working chamber 2.

The operation of the device according to the invention consists in shifting the ballast 4 by means of the lead screw 5. As a result of the movement of the ballast 4 on the lead screw 5, to the right or left from the drive unit 3, along the axis of the working chamber 2, the position of the center changes the gravity of the entire object. At the same time, a torque is generated, due to the force of gravity, which causes the fuselage 1 to rotate around the horizontal axis, thereby submerging the part of the fuselage 1 in which the ballast shifting occurs 4. In the crew compartment 7 there is a cabin with a crew, which car is only during the dive. is suspended gyroscopic. The immersion depth of the object hull depends on the amount of ballast shift 4. The maximum immersion depth is approximately half the length of the object hull.
