With the deep development of the field of marine environment monitoring, more and more marine environment monitoring instruments are put in the sea bottom or the whole marine profile by scientific researchers, such as profile observation buoys, submerged buoys, seabed bases and the like, and the type and the manufacturing cost of the sensor are higher for meeting the requirements of various marine observation parameters. The sensors need to be recycled after a period of operation to play back the data observed during the bit. Therefore, the acoustic releaser is used as a relatively stable underwater equipment auxiliary recovery tool on the present world, and a simple implementation mode and stable working performance of the acoustic releaser are necessary equipment for scientific researchers to recover equipment in the field of marine environmental monitoring.

The working principle of the acoustic releaser is that a release unit of the releaser is connected with the bottom of an anchor system (generally a gravity anchor or a gravity base), after an acoustic signal is sent to a submarine unit through a deck unit, the submarine unit is opened and then drops off from the bottom of the anchor system, and then the remaining sensors float out of the water through a floating ball in the anchor system, so that the recovery of underwater equipment is completed.

The existing releaser has unsatisfactory effect in deep water (generally, when the water depth is more than 3000 meters), once a single acoustic releaser fails in work, a release unit cannot be successfully separated from the bottom of an anchor system, and underwater equipment cannot be recovered.

In addition, the strength and the life of the connecting portion of the acoustic releaser are low due to the material and the weight, and if the releaser with high breaking force, high strength and long life is used, the cost is increased, so that the key technology for increasing the service life of the releaser is to further strengthen the releasing unit of the releaser and simultaneously reduce the load of the releasing unit.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The utility model provides a parallel seabed acoustics release mechanism, as shown in figure 1, including two releaser bases 1 fixed side by side, through 3 connecting steel sheet 3 and bolted connection between two releaser bases 1, set up sacrificial anode zinc plate 4 on the connecting steel sheet 3, can play the electrochemical corrosion effect that prevents the sea water.

As shown in FIG. 2, the base 1 of the releaser is formed by fixing two L-shaped steel plates 5 through a plurality of bolts, and a gap capable of accommodating the release hook 2 with the thickness of 350mm is reserved between the L-shaped steel plates 5. The acoustic releaser 6 is fixed between the two pieces of L-shaped steel plates 5 of the releaser base 1 by fixing clips 7.

One end of each releaser base 1 is provided with a release hook 2, as shown in fig. 3, the release hook 2 is provided with a bolt hole 21, a bolt for fixing the releaser base 1 is taken as a rotating shaft 8 to freely rotate, and a bolt for fixing the releaser base 1 is taken as a limiting bolt 9 to limit the rotating angle of the release hook 2. When the release hook 2 is in a loose state, as shown in fig. 5, the upper edge 10 of the barb of the release hook 2 is attached to the limit bolt 9, at this time, the first bow shackle 11 is connected with the release hook 2, after connection, the release hook 2 is rotated counterclockwise until the lower edge 12 of the barb is attached to the limit bolt 9, as shown in fig. 4, at this time, the connecting hole 13 on the release hook 2 is connected with the release unit of the acoustic releaser 6 through the connecting buckle 14 and the connecting shaft 15 and the release hook 2 is locked, and the first bow shackle 11 in the hook is fixed. The bow shackles 11 held by the release hooks 2 in the two release bases 1 are connected by an anchor chain 16 and pass through a connecting ring 17, which connecting ring 17 can be connected to the lower anchorage in any way.

The other end of each releaser base 1 is sleeved in a chain ring fixing bolt 22 of the fixed releaser base 1 by a chain ring 18, the chain rings 18 of the two releaser bases 1 are respectively connected with two holes of a three-hole plate 20 by two bow shackles 19, and the other hole of the three-hole plate 20 can be connected with an upper anchoring system by any mode.

The torque ratio of the distance between the rotating shaft 8 of the release hook 2 and the bow shackle 11 to the release unit of the acoustic releaser 6 is 1:3, which is 3 times higher than the maximum tensile load when the release unit of the acoustic releaser 6 is directly connected, so that the problem of low strength of the release part of the traditional acoustic releaser can be solved, and the cost of the acoustic releaser is greatly reduced.

Because the tapping can punch wantonly to two L shaped steel boards of releaser base 1, consequently can install the acoustics releaser 6 of arbitrary model additional on each releaser base 1, be connected to release hook 2 with the release unit of acoustics releaser 6 after the installation is accomplished and will release hook 2 and rotate to the barb down along 12 paste tight stop bolt 9, form and use the lever of 2 axis of rotation of release hook as the fulcrum, will release hook 2 and firmly pin and do not take place the unhook.

When the deck unit sends a release signal to any one of the acoustic releasers 6, the motor can loosen the connecting shaft 15 and separate the connecting buckle 14, so that the release unit of the releaser 6 is separated from the release hook 2, the release hook 2 rotates clockwise under the action of gravity, the bow shackle I11 in the barb slides out, the anchor chain 16 passes through the connecting ring 17, the lower anchor system is completely separated from the whole anchor system structure, and the release process is completed.
