Description

The invention relates to the field of transport engineering, in particular to floating equipment, and can be used for pumping out sea water entering the vehicle body when it is damaged.

The invention is known: “A device for pumping water out of ships, etc. floating bodies during their course" (USSR author's certificate No. 18621 A1 IPC B63B 13/00, B63B 19/26 dated November 30, 1930), which consists in the fact that for pumping water out of ships, etc. floating bodies during their movement, characterized by the use of a V-shaped tube, pre-filled with water, installed in various places of the vessel, equipped at the end lowered to the bottom of the vessel with a check valve and at the other end, brought overboard below the water level, with a cone-shaped nozzle with a funnel , facing the direction opposite to the movement of the vessel, which device aims to pump water out of the vessel by using a vacuum at the funnel.

The disadvantage of this invention is that this device is not capable of pumping out water during reverse motion, free descent along the river, as well as when the vessel stops, etc. floating bodies, due to the inability of the vacuum in the wide nozzle to cause an imbalance of the liquid in the siphon by sucking in the liquid due to the lack of air rarefaction created due to the vacuum when the vessel moves, etc. floating bodies In this case, the reserve of buoyancy is not preserved.

The closest to the proposed invention is the invention: “Drainage complex of a floating vehicle” (RF patent for invention No. 2246043 IPC F04D 13/02, F04D 9/04, B63B 13/00 dated 02/10/2005, Bulletin No. 4), containing pumping units with a drive for removing water from sections of the vehicle body, a system of pipelines, water intake and valve devices, and each pumping unit is made with a high-capacity centrifugal pump used to remove water from sections of the vehicle body in an emergency, and a low-capacity sump pump, used to fill the centrifugal pump when it is turned on and to remove water from sections of the vehicle body in a normal situation, while a water intake with a normally closed high-capacity device is installed between the pump and the pump, and the centrifugal pump and the pump are connected through a pipeline and a water intake to form together with a suction pipe of a centrifugal pump and drainage pipelines located behind the pump, a single drainage line, and the working cavities of the centrifugal pump are used as a sequential element of such a pipeline for a drainage pump when removing water from sections of the vehicle body in a normal situation, while acting as a drainage drive The pump uses an electric motor, and a hydraulic motor equipped with a device for axial unloading of the drive shaft is used as a drive for the centrifugal pump. In this case, the device for axial unloading of the drive shaft of the hydraulic motor is made in the form of a hollow, sealed intermediate support mounted on the housing of the centrifugal pump, inside of which an intermediate shaft is installed on bearings that limit the axial displacement, connected to the impeller shaft of the centrifugal pump, and the drainage complex is made with two pumping units. installations located in sections isolated from each other on opposite sides, and the water intakes of the pumping installations are interconnected by a water conduit with a built-in controlled valve device located in turn in the sectional partition of the vehicle body. Moreover, the drainage complex is made with pumping units, the number of which corresponds to the number of sections of the floating vehicle; a centrifugal pump with a capacity of 1600 l/min is used as a high-performance pump, and a pump with a capacity of 100 l/min is used as a drainage pump.

The disadvantage of this invention is that this drainage complex of a floating vehicle is not capable of pumping water when the electrical power supply is not working, as a result of which it is not possible to turn on the electric motor of the drainage pump, as well as start the centrifugal pump. In this case, the reserve of buoyancy is not preserved.

The purpose of the invention is to preserve the buoyancy reserve of a floating machine when overcoming a water obstacle without the use of electrical energy sources, after damage to the hull and the entry of sea water into the machine.

The technical result is aimed at maintaining the buoyancy reserve of a floating vehicle when overcoming a water obstacle without the use of electrical energy sources, after damage to the hull and the entry of sea water into the vehicle.

The technical result is achieved by the fact that in a device for pumping water from the body of a floating machine, containing a valve device, an intake pipe, according to the invention, a flask is additionally installed, mounted on the bottom of the body of a floating machine with the help of supports and placed on top of the intake pipe with a bypass valve, a drain pipe, an air chamber with a valve device and an air tube removed from an air cylinder with a tap filled with compressed air, which is located near the driver (driver).

The invention will make it possible to maintain the buoyancy reserve of a floating machine when overcoming a water obstacle without the use of electrical energy sources, after damage to the hull and the entry of sea water into the machine.

The device is illustrated by drawings:

In fig. 1 shows a side view of a device for pumping water from the body of a floating machine in its initial position, FIG. Figure 2 shows a side view of a device for pumping water from the hull of a floating machine in working condition when overcoming a water barrier after damage to the hull and the flow of sea water into the machine, where 1 is a valve device; 2 - intake pipe; 3 - flask; 4 - support; 5 - bypass valve; 6 - drain pipe; 7 - air chamber; 8 - air tube; 9 - air cylinder; 10 - tap; 11 - body of a floating machine.

The device is attached to the lower base, inside the body of the floating machine and contains a valve device 1, an intake pipe 2, a flask 3 installed on the bottom of the body of the floating machine 11 using supports 4 and placed on top of the intake pipe 2 with a bypass valve 5, a drain pipe 6, an air a chamber 7 with a valve device 1 and an air tube 8, removed from an air cylinder 9 with a valve 10 filled with compressed air, which is located near the driver (driver).

The operation of the device for pumping water from the body of a floating machine is as follows:

In the initial state, when overcoming a water barrier, the air tank 9 is closed, the valve device 1 is closed and does not allow sea water to enter the machine through the drain pipe 6, the air chamber 7 and the intake pipe 2. The bypass valve 5 is closed and prevents the air chamber 7 from communicating with the cavity " c » inside the flask 3.

When the hull is broken in the area of the waterline or below while the floating machine is overcoming a water obstacle, water begins to flow through the hole into the hull of the floating machine 11, which leads to an increase in its mass, a deeper subsidence and a decrease in buoyancy reserve. Water enters through the lower part of the flask 3 to the upper cut of the intake pipe 2, and the air in the flask 3 is displaced inside the intake pipe 2. After the intake pipe 2 is completely flooded, the driver opens valve 10 on the air cylinder 9 of the device, as a result which causes air to flow through the air tube 8 into the cavity “ a ” of the air chamber 7. In the cavity “ a ” the pressure increases, as a result of which the valve device 1 opens, and the air exits through the drain pipe outside the body of the floating machine 11. This leads to creating a vacuum in cavity “ b ”, as a result of which the bypass valve 5 opens. In cavity “ a ” a decrease in pressure occurs, and in cavity “ c ” an area of reduced pressure is created inside the flask 3. Due to the difference in pressure inside and outside the flask, water from the machine body is sucked into the intake pipe 2, enters through the bypass valve 5, the air chamber 7, the valve device 1 and the drain pipe 6 into the aquatic environment outside the body of the floating machine 11, which allows you to save the reserve buoyancy of a floating machine.

Thus, when using a device for pumping water from the hull of a floating machine, the buoyancy reserve of the floating machine is preserved when overcoming a water barrier without the use of electrical energy sources, after damage to the hull and the entry of sea water into the machine.
