Abstract

FIELD: sonobuoys for studies of world ocean.

SUBSTANCE: proposed sonobuoy has hermetic body, electronic modules of measuring and control devices, detection devices, separable ballast weight and hydrostatic disconnectors mounted on separable ballast weight. In the aft section of buoy there are two coaxial blind holes on opposite sides where ends of rods of hydrostatic disconnector pistons are mounted; they include hydraulic cylinders with rods-pistons, compression springs and adjusting screws. Hydraulic cylinders have through holes for admitting sea water to before-piston cavity. Such construction of buoy makes it possible to submerge it to assigned depth and to surface due to natural gravitational forces and hydrostatic pressure of water with no consumption of onboard power.

EFFECT: enhanced efficiency; reduced power requirements.

Description

The invention relates to marine engineering and is intended to study the acoustic properties of the aquatic environment of the oceans at various depths.

Autonomous stations for studying the aquatic environment in depth are known. For example, a buoy station on A.S. USSR No. 1062111, class ВВВ 22/06, 1983, as well as patent for 1996. Each such station contains a container with a set of measuring modules, a system of transceiver information and an onboard control system.

A common drawback of these stations is the need for the use of anchors and buoys for them, complicating the overall design of the station and making it difficult to set and lift them. In addition, the operation of onboard immersion systems requires significant energy consumption of onboard power supplies.

Known autonomous oceanographic probe by AS USSR No. 1286461, class B63B 22/00, 1987, comprising a container with measuring equipment and a ballast weight connected to the container through a hydrostatic disconnector. This probe is accepted by the authors as a prototype of the invention.

The main disadvantage of the prototype is the presence of a very complex electrical mechanism included in its structure, which ensures the operation of a hydrostatic disconnector and requires additional consumption of on-board power.

The aim of the present invention is to provide a sonar buoy for exploring the oceans, free from mechanical connections with support ships and anchor systems, capable of sinking to any designated depth and floating to the surface without the use of additional energy.

This goal is achieved in that a sonar buoy for exploring the world’s oceans, containing a sealed cylindrical body, electronic modules with measuring and recording equipment, detection devices, detachable ballast cargo and hydrostatic disconnectors installed on a detachable ballast cargo. In the aft part of the hull on opposite sides two coaxial blind holes are made, which include the ends of the piston rods of the hydrostatic disconnectors, consisting of hydraulic cylinders containing piston rods, compression springs and adjusting screws. The hydraulic cylinders are equipped with through holes for the entry of sea water into the pre-piston cavities.

The introduction of hydrostatic disconnectors allows you to use the natural strength of the hydrostatic pressure of the seawater, which increases in proportion to the depth of immersion of the buoy, and automatically separate the ballast cargo at the designated depth.

The device of the proposed buoy shown in Fig.1.

Figure 2 shows a section of a hydrostatic disconnector.

The buoy (see Fig. 1) consists of a sealed housing 1, in which electronic modules of measuring 2 and recording equipment 3 and detection devices 4 are placed. 4. In the aft part, the buoy body has blind holes 5 on the opposite sides, into which the ends of the piston rods are hydrostatic disconnectors 6 mounted on detachable ballast cargo 7.

Each disconnector (see figure 2) contains a hydraulic cylinder 8, in the cavity of which a piston rod 9, a compression spring 10 and an adjusting screw-piston 11 are installed. The pistons are sealed in the hydraulic cylinder by rubber rings 12. The end face of the hydraulic cylinder from the piston rod side has through holes 13 for entry of sea water into the pre-piston cavity 14.

With this design of the disconnectors, you can create a buoy immersion depth by selecting the stiffness of the compression spring 10 and smoothly adjusting it with screw 11. And the buoy's immersion (ascent) speed can be set by selecting its negative (positive) buoyancy.

The buoy operates as follows.

After descent from the surface ship to the water, the buoy begins to dive under the influence of negative buoyancy created by the detachable ballast weight 7. At the same time, the on-board electronic equipment complex automatically turns on. A study of the oceans is carried out according to a given program and registration of the information collected.

Detectors periodically send acoustic signals to the environment, by which a surface ship determines the bearing on a working buoy. Increasing with depth, the hydrostatic pressure in the pre-piston cavity 14 biases the piston rod 9, compressing the spring 10. Upon reaching the prescribed depth, the hydrostatic pressure moves the piston rod by the amount of piston rod entering the blind hole 5 of the buoy body. Ballast cargo 7 with disconnectors fixed to them is separated from the buoy.

After separation of the ballast, the buoy acquires positive buoyancy, under the influence of which it floats up, continuing research and marking its place with periodic acoustic messages.

A buoy which has surfaced to the surface is detected by a supporting surface ship, is caught and boarded, after which the registered information is processed.

According to the invention, a mock-up of a buoy was developed and manufactured, which successfully passed the tests.
