Description

The present invention relates to marine engineering and can be used to raise deep water to the surface in order to comprehensively study their physical and chemical properties.

A well-known ocean pump that uses the energy of surface sea waves to lift deep sea water [1]. The device consists of a cylinder with a piston rigidly connected by means of a rod with a float element, and a pipe attached to the lower fitting, the lower end of which falls to a predetermined depth. The pump is attached to a floating platform or anchored. On the piston and in the pipe, bypass valves are located in depth, consisting of an elastic membrane that overlaps the bypass holes in the piston or on the disk of the bypass valve. The design is complemented by stroke and piston stroke limiters.

The known device allows you to raise deep water to the surface from the studied object for the analysis of radioactivity and other purposes. The disadvantage of the Ukrainian patent is its constant presence on the surface and, therefore, the possibility of its destruction in stormy weather.

A device for stationary selection of water in the bottom layer, consisting of a reinforced hose, the upper end of which is fixed for buoyancy, and the lower end - on the intake chamber and using a ballast weight is installed at the studied depth, while the reinforced hose is connected to a flexible hose at the location of the buoyancy [2].

This device also has disadvantages, which are the difficulty of installing a water intake chamber at the study site, the low reliability of its operation and the inability to draw water at any depth.

The purpose of this proposal is to increase the reliability of the device and expand its technical capabilities.

This goal is achieved by the fact that in the known device, consisting of a reinforced hose, the upper end of which is fixed to buoyancy and connected to a flexible hose, and the lower end is mounted on the water intake chamber and using ballast weight, a tubular swivel is installed at the top of the buoyancy, which connected to a flexible hose, the end of which is mounted on a winch mounted at the bottom of the float, and connected to an axial coupling of rotation, passing into the support pipe, led up to the float. In addition, the winch drive has a controlled latch and is electrically connected to the sonar command unit, while the command unit and the winch drive have different power sources.

These differences are related to the goal as follows: The connection of the reinforced hose to buoyancy through a swivel with a flexible hose wound on a winch mounted on a float and controlled by a hydroacoustic signal allows you to get rid of the presence of surface water intake elements and thereby get rid of the destructive effect of storm waves on device performance. Various power sources for the winch drive and the command block with a latch allow after a long time the device is at the point of water intake to reliably separate the float from buoyancy, with the aim of access to the deep water intake pipe of the control vessel. The energy for the control operation is provided only by the actuation of the winch latch. The intake pipe is delivered to the surface by the work of the float.

The possibility of practical implementation.

Figure 1 shows a device for regular water withdrawal from controlled depths of the ocean. It contains a water intake chamber 1, a reinforced hose 2, a union nut 3, fastening the reinforced hose to the buoys 4, a tubular swivel 5, which allows the flexible hose 6 not wound on a winch 7, mounted on the float 8 to rotate the latter. The winch is rotated by a drive 9, electrically connected to a hydroacoustic command unit 10. The drive has a controlled latch (not shown in the drawing), which allows the winch to rotate only towards the winding of the flexible hose 6. The opposite side of the winch 7 is connected via a rotation sleeve 11 to the support pipe 12, hinged up to the top of the float 8 and mechanically closed (to prevent clogging) 13. At the top of the float, to raise it aboard the vessel, loop 14 is fastened. In addition to the above-mentioned structural elements in the drawing, an object under study 15, located on the bottom 16.

Figure 2, illustrating the use of the device in the ocean, additionally shows: a working vessel 17, located on the sea surface 18, with a pilot port 19, through which the already mentioned float 8 on a flexible hose 6 is brought on board the vessel.

The use of the device in the ocean is as follows. At the intended control point (depth is known), the ballast weight is lowered on the cable (not shown in the drawings). At the required depth (from where water will be drawn), the intake chamber is attached to the cable and then the ballast and chamber 1 are synchronously lowered on the reinforced hose 2. Without reaching the bottom, 20-30 m before it, the cable is fixed on the reinforced hose and formed on board the vessel a union nut 3, which is screwed to buoyancy 4. The buoyancy is already connected (via the swivel 5) with a flexible hose 6 wound on the winch 7, the length of which exceeds the remaining meters to the bottom by 2-3 times. This length should be sufficient in the future to raise the float 8 on board and lower it below the waterline inside the vessel. The buoyancy 4 is carried overboard together with the float 8, the cable with a reinforced hose is pushed overboard until the ballast reaches the bottom. Additionally, 40-50 m of the cable is etched and a signal buoy is attached to it. Water withdrawal point formed.

To check the operation of the device, a hydroacoustic signal is generated, which causes the latch to be released on the winch drive 7. The float 8 in the place with the winch floats up, hooks it to the loop 14 with a hook, makes it through the port 19 into the vessel 17 and lower it below the water line 18. Connect to the pipe 12 a small vacuum compressor, and water, breaking several tens of meters of flexible hose 5, enters the ship. The compressor can be disconnected since gravity water will flow on board the vessel. At a real jet velocity of 1-2 m / s, water from a depth of 5 km will arrive in half an hour.

After taking the water, the float 8 is carried overboard, a command is given to turn on the winch and it descends to buoyancy 4. The device is ready for the next selection.

The hydroacoustic command unit must have a transponder, which, when requested from the vessel, will clearly fix the location of the float 8 and avoid tangling the signal buoy cable and flexible hose 6 when the float emerges. To do this, when approaching the vessel to the sampling point, it is enough to take a signal buoy on board, the opposite of finding buoyancy with a float.

Modern power sources allow the sonar channel to keep workable for 1-2 years. During this time, the control vessel will definitely visit the sampling point and when the float emerges, the batteries will be replaced. Stormy weather at the installation point of the device will not damage it. A small signal buoy will not cause a buildup of submerged buoyancy 4, because it must maintain the verticality of the reinforced hose. Even with its separation, the device will remain operational and modern navigation aids will allow it to operate for any length of time.
