Description

The invention relates to the field of underwater shipbuilding, and more particularly to control systems for immersion depth.

A well-known depth stabilizer with equalization tanks located in a sturdy housing (A.B.Shirokorad. Soviet post-war submarines. M., 1997, p. 163, 199).

The disadvantage of the analogue is the need for periodic use of pumps to remove water from the surge tank, which is unacceptable in the mode of increased stealth of the submarine without running.

Known stabilizer depth of immersion of a submarine without stroke according to the patent of the Russian Federation No. 2154592, B63G 8/22, containing a surge tank with a device for removing and receiving water and characterized in that the surge tank is made in two sections, placed outside of the solid hull in the tanks of the main ballast and is equipped with receiving and casting kingstones, air-steam and safety valves, air and test taps, while in the lower part of each section heating elements are installed in the form of wire electrodes, located horizontally, and adjacent grids have different polarity.

If the submarine is “heavy” and sinks, then the signal from the depth sensor, converted to voltage with a plus sign, goes to the actuators for supplying power to the electrode grids, to the actuators of the steam-air valve to close it and the receiving-cast kingston to open it after receiving a signal from differential pressure sensors about the excess pressure in the equalization tank over the pressure in the tank of the main ballast by a predetermined value. The vaporization rate in the equalization tank is regulated by the immersion speed sensor by changing the electrical load.

If the submarine is "light" and pops up, the sensors give a signal with a minus sign, which arrives at the actuators and causes the steam-air valve, receiving-casting kingston to open, water intake into the equalization tank until the submarine's ascent stops. After a series of oscillations, regulated by the feedback value of the automatic system, the position of the submarine is stabilized.

The use of a non-pump stabilizer of the submersion depth of the submarine without a stroke improves the vibro-acoustic characteristics in the mode of increased stealth.

The specified technical solution according to the patent of the Russian Federation No. 2154592 is taken as a prototype.

A disadvantage of the known technical solution according to the patent of the Russian Federation No. 2154592, adopted as a prototype, is the need to place a special equalization tank in the tank of the main ballast equipped with appropriate fittings with actuators, which requires significant dimensions of the device. In addition, the placement of such a device in submarines with single-hull architecture is difficult.

The aim of the invention is to remedy these disadvantages, namely, reducing the size of the stabilizer depth of immersion of the submarine without running.

This goal is achieved in that, in contrast to the prototype, the signals of the depth sensors carry out the ejection of water from the circulation path in the vertical direction by opening and closing the kingstones. At the same time, upper and lower kingstones with drives are installed on the circulation path, connected to depth sensors through which water is ejected from the circulation path in the vertical direction.

The proposed method and device for its implementation are illustrated by the drawings shown in FIG. 12.

When implementing this method, the circulation path of the submarine is used, which pumps overboard water, the outboard water is released, as a rule, through wing-shaped adjustments 1 located on the outer hull of the submarine. It contains the upper and lower kingstones 2, 3 with opening drives 4, 5.

If it is necessary to stabilize the submarine without moving, the device operates as follows. When positive buoyancy occurs, open up Kingston 2, the water pumped through the circulation path exits in the vertical direction and compensates for the positive buoyancy. When negative buoyancy occurs, lower Kingston 3 is opened and negative buoyancy is compensated. The discovery of kingstones by the signals of depth sensors allows you to keep the submarine at a given depth without a move.

Thus, the presented description and drawings allow us to conclude that the claimed method and device for its implementation are new, differing from the prototype by such significant features as the implementation of the signals of the depth sensors of the ejection of water from the circulation path in the vertical direction by opening-closing kingstones installed on the circulation path, with the upper and lower kingstones with drives placed so that they emit water in the vertical direction, which allows so to complete the task, namely, to reduce the size of the stabilizer immersion depth of the submarine without a stroke, and infer the presence of inventive step and industrial applicability.
