(57) Abstract:Use: for lifting sunken vessels, pilotage with a large draught of the shallow lake forwater, as well as constituent elements of pontoon bridges, wharves, ferries, etc. Entity: pontoon comprises a sealed enclosure has a cylindrical shape with two end bottoms made with three concentric shells, the average of which is in a sealed cavity between the inner and outer shells with the possibility of extension, a source of compressed gas connected to the said cavity, and air valves. The body is equipped with sealing jumper installed in the cavity between the inner and outer shells and separating the said cavity into two symmetrical parts, the average shell is made of two parts, each of which is placed in the appropriate part of this cavity, and the walls of each stage, except the last, are hollow, and each subsequent stage is placed in the cavity of the previous stage with the possibility of longitudinal movement, equipped with a sealing gasket and a channel for supplying compressed gas into the cavity subsequent stage, and air valves installed. Can be used for raising sunken vessels, pilotage with great draft for shallow water, as well as constituent elements of pontoon bridges, floating supports floating bridges, wharves, ferries, etc.The famous floating pontoon structures containing hard waterproof case with hollows, which are placed in the containers associated with the body made of elastic, which increases the volume of the hull of the pontoon when filling them with compressed gas and limited along the hull of the pontoon clean in its cut-off position housings, each of which contains hard leaves pivotally connected together and enclosure pontoon (ed.St. USSR N 262639, 1969).The disadvantage of this technical solution are significant dimensions of the pontoon, the need to have large reserves of compressed gas for filling flexible containers, which leads to increased time to bring the pontoon in its working position, providing maximum displacement.Also known pontoon (prototype) , containing a sealed enclosure has a cylindrical shape with two end bottoms made with three concentric shells, the average of which reatogo gas, communicated with said cavity, and air valves.If necessary, increase the volume of the body of the pontoon compressed gas is fed into a sealed cavity. Upon receipt of gas for the nomination shell of the movable section.The maximum volume of the hull of the pontoon is limited, because the presence of one stage does not allow to increase the volume of the hull of the pontoon relative to the original more than 2 times. This reduces the performance of the pontoon.The aim of the invention is to eliminate this drawback.This is achieved by the fact that in the known technical solution, the body is equipped with sealing jumper installed in the cavity between the inner and outer shells and separating the said cavity into two symmetrical parts, the average shell is made of two parts, each of which is placed in the appropriate part of this cavity, and the walls of each stage, except the last, are hollow, and each subsequent stage is placed in the cavity of the previous stage, with the possibility of longitudinal movement, equipped with a sealing gasket and a channel for supplying a compressed gas into the cavity subsequent stage, and the air is; in Fig. 2 is a longitudinal section; Fig. 3 - pontoon in position when one of the parts of the body (left) is fully extended, and the moving speed of the other parts are in the assembled state.The hull of the pontoon by means of a sealing jumper 1 is divided into two symmetrical compartment 2. The compartments contain movable stage 3, the walls of which, except the last, are hollow. The movable stage from the free end facing the working cavity compartments with seals 4 and sealed by means of adapter ring 5 forms. Each subsequent stage is placed in the working cavity of the previous one. In the case of adapters each rolling step is performed at least one channel 6 gas supply in podporchennuyu cavity to the next level, and at the inlet of the channel is on the air valve 7 in a normally closed position. On the body of the piston sealing device of the movable stage is mounted insert 8 plug connector with the opportunity to interact with the block 9 when the extension of the movable stage to its full length. The air valve 7 is fixed by means of the brackets 10.Working cavities of the compartments through the three-position valves connect Vigny steps installed fittings 14 nadporshnevaya cavities and the tabs 15 podporchenyj steps in the open position. In the initial position, the sheath movable stages interact with the stops 16, made in the working cavity of the guide steps.If necessary, increase the volume of the body of the pontoon (see Fig.3) the valve 13 newportnews cavity is transferred to the position of the Drain and the gate 12 is in position "gas Supply". Upon receipt of the compressed gas in the working volume of the compartment for the nomination of the first stage. When the nomination to the full length of interaction of the contact insert 8 plug / socket connector with terminal block 9 is formed in the supply circuit of the air valve 7. After mounting the movable stage in the guide shells clamps 15 open the air valve 7. Compressed gas begins to flow into podporchennuyu cavity of the first movable stage, providing the nomination from her second stage. The nomination subsequent stage is similar.Bringing pontoon to its original position by successive return moving speed in its initial position, since the latter when open the valve 7. What valve 12 podpornoy cavity is transferred to the position of the Drain and the gate 13 is in the position of "gas" (previously through the pipeline with the for the third stage is retracted into the guide sheath of the second stage. Drainage podpornoy cavity passes through the open valves 7 intermediate stages and the valve 12. Return to the initial position of the second stage perform similarly when previously closed valve 7.Folding the moving speed of the pontoon prevent the tabs 15, which may be performed, for example, in the form of a spring-loaded latch, interacting with the body of the piston sealing device. Additional bracing may be provided by sealing the internal cavity of the pontoon by closing the vent valve, and the sealing of the working cavities compartments and moving speed. As a source of compressed gas can be used nassivera or compressor station. PONTOON containing a sealed enclosure has a cylindrical shape with two end bottoms made with three concentric shells, the average of which is in a sealed cavity between the inner and outer shells with the possibility of extension, a source of compressed gas in communication with the said cavity, and air valves, characterized in that the housing is provided with a sealing jumper installed in the cavity between its inner Polana of two parts, each of which is placed in the appropriate part of this cavity, and each part of the middle shell is made of multi-stage, and the walls of each stage, except the last, are hollow, and each subsequent stage is placed in the cavity of the previous stage, with the possibility of longitudinal movement, equipped with a sealing gasket and a channel for supplying a compressed gas into the cavity subsequent stage, and air valves are installed in the ducts for the air supply.
