Description

Known vessels are made up of units located one after the other, articulated between them pivotally in the median plane.

In the proposed vessel of this kind for transportation of bulk materials, in order to ensure the possibility of automatic unloading of the vessel into the water by gravity of the cargo itself, the links at one end are open, with the open ends of two adjacent links facing one another and equipped with ballast tanks. The hinges connecting the individual links are located on the lower edges of the open ends and on the upper edges of the closed ends, and the bottoms of the links and their closed ends are provided with air chambers.

In the schematic drawing of FIG. 1 shows a side view of the vessel in the position of bulk materials; FIG. 2 is a view of the vessel from above; FIG. 3- view of the intermediate link from the end; FIG. 4 is a side view of the vessel in the unloading position; FIG. 5 is a side view of the onboard spring-loaded stopper; FIG. b-cut polyname AB in FIG. five; FIG. 7 is a side view of the latch between the links of the vessel (section along the line C D in Fig. 3).

In shape of its hull, the vessel is a flat-bottomed river barge with a spoon-shaped bow and ski-like stern. It consists of two deaf / 2-feed and 2-feed links, and several, in this particular case, eight intermediate links 3 (Fig. 1, 4). Each of these latter is a rectangular open box with a double bottom 4, double sides 5 (Fig. 3) and a double impermeable bulkhead b at one of the ends. The link is pivotally interconnected so that the open end of one link comes against the open end of a neighboring link. The hinges are located on the lower edges 7 (Fig. 4) of the closed ends of the links and on the upper edges 8 of their open ends. The double bottom space 9 (Fig. 3, 4) near the open end of each link is separated at a distance of 1 m by an impermeable bulkhead to form a water ballast tank, and the remaining parts of the bottoms and closed ends form air chambers. In order to provide the possibility of forced blocking of links, JO chains (Figs. 1, 2, 4), which are pulled by winches, and latches 12 (Fig. 7) are applied.

To protect the links from jerks and excessive opening during material unloading, side-mounted stoppers 73 (Fig. 4, 5, b) were used in the form of spring-loaded arc joints located between the side walls 74 and 15.

The ship is loaded with coal at rigidly interconnected links in bulk before they are loaded onto the load waterline; to unload the coal into the pool, automatic couplings open from the deck, while loosening the tension of the upper chain. Under the pressure of the weight of the coal on the ends that do not have transverse bulkheads, the links tilt in the longitudinal direction (Fig. 4), and the coal rolls down from the bottom of the link into the water.

To increase the angle of inclination and protect the link from prematurely (before the end of the coal eruption), straighten it to an even keel into the ballast tank located near the open end of the link, before starting unloading through the side clinkers let in water.

After the coal is unloaded, water from the tanks is removed through bottom valves by blowing the tanks with compressed air using compressors located on each link.

The vessel is equipped with two diesel ship power stations and two electric winches operating at its current: (the base and for the tension of the on-board brake circuits) and the unit for charging with a compressor.

The described vessel is intended to automatically unload coal into special pools for storage under water in order to avoid weathering.

The subject matter of the invention.
