    (AOR DEVICE FOR AUTOMATIC REGULATION OF DEPTH OF TOWED TOWNS IN WATER DRAWING It is known a device for regulating the depth of the seismic cable, containing an undeformable wing, made with the possibility of rotation around an axis rigidly fastened with the object being towed, and means for changing the angle of inclination of the wing depending on the depth of the towed cable 1. The closest to the proposed technical essence and the achieved result is the device for automatic adjustment of the depth of the towed in water object, containing a non-deformable OBJECT. wing enclosed between the side walls and formed by the upper and lower surfaces, made with the possibility of movement around the axis of rotation, gesture associated with the object, and an automatic mechanism for adjusting the depth of immersion, made in the form of a pressure-sensitive element associated with the mechanism for converting the deformation movements of the element into rotational movement of the wing 2. The disadvantage of these devices is their low sensitivity, which is associated with small relative to the size of the wing dimensions of the sensitive element. The aim of the invention is to increase the sensitivity of the device. The goal is achieved in that a device for automatically controlling the depth of an object towed in water, comprising a wing formed by the lower and upper surfaces, enclosed between two side walls and adapted to move around an axis of rotation rigidly connected to the object, and automatically the mechanism for adjusting the depth of immersion, an additional pivot axis and a deformable element are introduced, with the lower and upper surfaces of the wing being pivotally fixed at one end to the other about an axis and connected at the other ends by a deformable element, and the automatic adjustment mechanism contains means for creating a shear force between the lower and upper surfaces equal to the force generated by the hydrostatic pressure at a given depth, and a transformation system and; m shear force to rotate the wing around the axis of rotation, with the means for forming shear forces between the lower and upper surfaces are made either in the form of a manometric box located inside the core either the ends of which are fixed on said surfaces, or contain an inflatable edge, also located inside the wing, and springs fixed on said surfaces, the transformation system contains a rod rigidly connected to the wing, and its ends are placed in elongated holes shapes made in the side walls and having an extension direction different from the direction connecting the axis of rotation and said rod. FIG. 1 shows the first embodiment of the wing, a general view; in fig. 2 is a deforming plate connecting the two surfaces of the wing; in fig. 3 - lateral joint between two side walls of the wing, partial section; in fig. - wing in the dive position, cut; in fig. 5 wing in the middle position, cut; in fig. 6 - wing in the ascend position, incision; in fig. 7 - the second version of the wing design, a general view. In the first embodiment (Figs. 1-6), the device includes a wing 1, having a first profiled surface or upper surface 2 and a second profiled surface OR a lower surface 3, the rear edges of which (flow edge) are connected using a hinge f, and the front edges They are joined by means of a bent 938 plate 5 made of a deformable material by the method of formation (Fig. 2) and forming the leading edge (edge of attack) of the wing. Both wing plates have side walls 6 and (Fig. C). The upper plate of the wing 7 is adapted to slide into the lower plate. The internal volume of the wing is not hermetically sealed external environment. When the device is in the submerged state, the internal volume of the wing is filled with water. In the transverse direction, the wing necresists the rod 8, which represents the axis of rotation, fixed in bearings 9, which are fixed, for example, on the inner surface of the upper wing plate. The two side plates or walls 10 and 11 are located on both sides of the wing, parallel to the side walls of both plates, and rigidly fastened to each other with a rod and two spacers 12, and 13. The plates have holes 1 that allow the device to be fixed on the submerged element which needs to be stabilized at a constant depth. Inside the wing there are one or several manometric boxes 15 having a cylindrical shape and deforming only along the axis of rotation. The end surfaces of the boxes are bolted 16 to the lower and upper plates. Gauge boxes can be made, for example, of rubber, reinforced with metal rings. Valves 17 are brought to the outer surface of the upper plate, allowing the pressure gage boxes to be inflated to a certain pressure. A rod 18 is also located inside the wing. It penetrates the side walls of the bottom plate of the wing, and its ends are located in two slots x 19 of elongated shape, made in side walls parallel to the walls of the wing. The rods located inside the wing, which are fastened to the upper and lower plates, are located on both sides of the place where the pressure boxes rest against both roof plates; , and, moreover, the rod 8 is located to the wing attack edge, the elongated slits are made with a certain inclination relative to the segment of length D (Fig.) connecting the two rods, but, for example, strictly parallel to the transverse axis of the wing, i.e. in the case when the wing is in the middle position, providing movement at a constant immersion depth (Fig. 5, the distance D between the rods is selected depending on the height of the metric boxes, so that the wing took a middle position at the moment when the gas pressure inside the boxes balanced the external hydrostatic pressure corresponding to the specified depth. The distances R and between the hinge and the said rods should be constant. If the entire complex towed in the submerged state drops below the level at which the wing is in the middle state, the hydrostatic pressure begins to exceed the gas pressure in the gauge boxes, resulting in the boxes being compressed along their axes. Lower and upper wing plates the distance 18 decreases between the rods I. The rod 18 moves in slot 19 in the direction of the wing of attack. However, since the distances are R and RX. constant, such a displacement becomes possible only as a result of turning the hinge downwards (Fig. 6). The edge of attack of the wing moves upwards, as a result of which, under the action of hydrodynamic traction, the wing, together with the entire towed element, rises and reaches a predetermined depth. As soon as the pressure is achieved, the wing will return to the middle position again. If the entire complex towed in the submerged state rises above a predetermined depth (the wing in the middle position hydrostatic pressure becomes lower than the pressure of gas in the manometric boxes. The boxes expand along the rotational axis and tend to increase the distance between the wing plates (Fig.)). The distance increases, and the rod 18 moves away from the rod 8, moving into the slot 19. However, such movement becomes possible only by turning the hinge upwards. The wing edge of the wing deflects downwards and the hydrostatic pressure generates a force that tends to return the wing to a given level. In the second embodiment (Fig. 7}, the wing is hinged on the support 21, which has the shape of a bent pipe) using a rod and parts 20. corresponding to the desired immersion depth. As in the first embodiment, the bag may communicate through the valve 23 with a reservoir with a capacity exceeding the volume of the bag and containing pressurized fluid. The springs 2A are fixed one with the end to the upper wing plate and the other end to the axis 18 rigidly connected to the lower wing plate. The section of the third section 21 and the parts 20 can be replaced by plates 10 and 11 (Fig. 1 or any other appropriate fastening system. Principle This device is identical to the principle of operation of the device according to the first embodiment.However, when the bag is compressed by the hydrostatic pressure exerted by the water contained in the wing, it cannot bring together the two wing plates if it is not attached to the wing. The role of the springs 2k is that they bring the wing plates together, thus giving the attack edge a possibility to deflect upwards. In both designs, before immersing the device in the manometric boxes 15 or in the bag, air is pumped at a pressure equal to the hydrostatic pressure at a predetermined depth, which inevitably exceeds atmospheric pressure. As a result of this, the wing occupies the position shown in FIG. k. When the device is immersed in water, the immersion speed (rather high at first gradually decreases as the wing moves to its middle position. The immersion stops as soon as the pressure is equal. The design of the proposed device also implies the replacement of pressure gauge or elastic bag
    which may be altered by pressure.
