    (54) I WILL MAKE TO RADIATE ACOUSTIC WAVES IN LIQUID THROUGH IMPULSE
    one
    The invention relates to devices for emitting acoustic waves in a liquid through implosion with a sudden change in the volume of a submerged sealed chamber, in particular, used in the field of marine seismic surveys.
    A device is known for emitting acoustic waves in a liquid by means of an implosion, which contains two elements that are movable with respect to each other and are connected along the periphery by at least one flexible membrane, which forms a variable volume sealed chamber with the moving elements, means for diluting the movable elements and J5 fixing them in the divorced position, made in the form of a first cylinder connected to one of the moving elements with a piston, the ipock of which is installed with the ability to interact with another mobile electric element the volume, the distribution system of hydraulic fluid to create intermittent pressure on the piston, made in the form of a second cylinder, fixedly mounted relative to the first cylinder, the source P1D1)
    fluid and hydraulic fluid distribution circuit 1.
    A disadvantage of the known device is the complexity of the design of the distribution system of hydraulic fluid and the means of breeding the movable elements.
    The purpose of the invention is to simplify the construction of the means of dilution and fixation, as well as reducing the length of the distribution circuit of hydraulic fluid. .
    This goal is achieved by the fact that in a device for emitting acoustic waves in a liquid by means of an implosion, the distribution system is equipped with a valve with a stem, the cross section of which is smaller than the cross section of the valve head, and the second cylinder has two compartments communicated periodically by means of the first hole hydraulic fluid and the environment through a two-way valve, and the other compartment through the second hole periodically with the first cylinder and at least through the third bore hole It is constant with the environment, the valve is installed in the second cylinder with the possibility of simultaneous overlapping of the first and second holes and has a through channel formed parallel to the longitudinal axis of the valve, in which a spring-loaded, stop valve is additionally installed, the spring of which is connected on one side with a shut-off valve, and on the other - with the opposite wall of the second cylinder. In addition, a protrusion is formed on the side surface of the second cylinder, having a seat for the valve head and defining a first port. A layer of damping material is placed between the two movable elements to soften the impact that occurs. the moment of their contact. FIG. 1 shows schematically a device with a partial section; in fig. 2 the location of the distribution system in the proximity of the moving elements; in fig. 3 - the same, with the divorced position of moving elements; in fig. 4 is the same, with the intermediate position of the moving elements between the diluted and contiguous positions. The device contains movable elements 1 and 2, made in the form of round plates on the periphery connected by flexible membranes 3, fixed by a flange 4, forming a sealed chamber 5 of variable volume, means for diluting the movable elements, made in the form of the first cylinder 6 with 7 a brush 8 in which a cavity 9 is formed, a system 10 for distributing hydraulic fluid to create intermittent pressure, made in the form of a cylinder I, with compartments 12 and 13 interconnected by an opening 14, a compartment 12 by an opening 15 in the wall 16 En with the source 17 of hydraulic fluid and the environment through a two-position valve 18, the compartment 13 with the hole 19 communicates with the first cylinder 6 and the hole 20 with the external environment, the valve 21 with the head 22 and the stem 23 and the through channel 24 in which the stop valve 25 is installed With the seat 26 and the spring 27, the protrusions 28 have a seat 29 of the valve 21 and the seals 30, tightness is ensured by the seals 31 and 32. The device operates as follows. When the movable elements 1 and 2 are in a contiguous position (Fig. 2), the distributor 18 directs the fluid under pressure through the opening 15 into the compartment 12 of the ciliidry 11 and through the channel 24 to the cylinder 6). The fluid pressure acts on the head 22 of the valve 21 and on the end of the rod 23, causing opposing forces; since the surface of the head 22 of the valve 21 is greater than the surface of the end of the rod 23, the force acting on the head 22 is greater than the force acting on the end of the rod 23, which causes the head 22 of the valve 21 of its seat 29 to cover, holding the rod 23 that has entered the hole 19, and hermetically closing it by means of a seal 31. The fluid entering the cylinder 6 under pressure through the channel 24 acts on the piston 7, causes the dilution of the moving elements 1 and 2 and holds them in the diluted position (Fig. 3). When the device is started up, the distributor 18 rotates to communicate the compartment 12 with the external low-pressure environment, which, due to the presence of the valve 25, causes a sharp drop in pressure and therefore reduces the force acting on the head 22 of the valve 21, and this force becomes less than the force applied to the end of the rod 23. The valve 21 opens, the compartment 12 is connected through the opening 14 to the compartment 13 and to the surrounding front through the opening 20. The pressure in the cylinder 11 drops, which accelerates the movement of the valve 21 and opens the opening 19. The pressure in the cylinder 11 becomes equal to the ambient pressure and the force with which the hydrostatic pressure acts on the movable elements 1 and 2, no longer counterbalanced action. the piston 7. Then the moving elements 1 and 2 abruptly approach each other, push the piston 7, which pushes the liquid out of the shield 6 into the external environment through the opening 20. At the moment of collision of both moving elements, a strong sound wave arises. The use of a distribution system that is open to the environment, which plays the role of a low-pressure fluid, makes it possible to avoid a branch pipe when the source of hydraulic fluid under pressure is installed and towing the vessel. An installation with a feed system and a source of hydraulic fluid under pressure on a floating platform or towed floating float is facilitated by the fact that the injection fluid is taken directly from the external environment. In the case of a seismic source operating in water, an important advantage of the invention is the use of this water as a hydraulic working fluid, however air can equally be used. Moreover, no intermediate mechanical part is required to move the piston to the dilution position of the moving parts.
