Abstract
The utility model relates to submarine navigation technical field, is specifically related to a kind of device for laying towed body.Underwater towed-body distributor, it connects towed body, and provides positive buoyancy for described towed body, its technical scheme is, before towed body enters water, is connected to unhook snap ring place by the trailing cable of towed body, after entering water, towed body is suspended in immediately below towed body distributor, tensioned, and bearing pin is subject to coupling mechanism force; When lash ship speedup traction, towed body is at lift effect float downward, and the intermolecular forces at trailing cable and unhook snap ring place reduces, the coupling mechanism force that bearing pin is subject to disappears, and operating personal pulls unhook hawser, pull-out bearing pin, under the elastic force effect of spring, unhook snap ring is separated, release towed body.The utility model effectively reduce towed body risk of collision and the possibility at the end, protect the cable sector of winch, achieve towed body safe, reliably lay.
Description
Technical field
The utility model relates to submarine navigation technical field, is specifically related to a kind of device for laying towed body.
Background technology
Towed body belongs to the one in underwater unmanned vehicle, and himself is drive not, needs rely on lash ship traction and utilize self gravitation to sink; When traction lash ship is static or lowsteaming time, the towed body of negative lift state is in the characteristic of water due to deadweight, and there is the tendency at the lower calm end, when therefore towed body lays, lash ship must move ahead with the higher speed of a ship or plane; And the risk that lash ship high speed operation state lays towed body is larger, and successfully possibility is little: a, hanging towed body under sail, to enter water abnormally dangerous; B, towed body have just entered instant water and have sunk fast, have the risk of collision lash ship; When c, the higher speed of a ship or plane lay towed body, cause trailing cable tension force to increase severely instantaneously incessantly, reduce sharply, reduce the trailing cable life-span, the impact load simultaneously suffered by winch will destroy cable sector.
Utility model content
The purpose of this utility model is: for making reliable and secure the laying of negative lift towed body, provide a kind of underwater towed-body distributor.
The technical solution of the utility model is: underwater towed-body distributor, and it connects towed body, and provides positive buoyancy for towed body, and it comprises: buoyancy tube, unhook hawser and unhook snap ring;
Buoyancy tube is open column shape structure, and adopts glass-reinforced plastic material; Two symmetrical metal installation rings are provided with at the outer wall of buoyancy tube;
Unhook snap ring is two sectional type structure, and one end of every section of unhook snap ring becomes an arcuate structure by pinned connection, and the other end is arranged on a metal installation ring place; One section of unhook snap ring place is provided with spring wherein, and spring connects the metal installation ring at this section of unhook snap ring and this place;
Unhook hawser sticks on the trailing cable of towed body, and one end connects bearing pin, and the other end is that free end is held by operating personal;
Before towed body enters water, be connected to unhook snap ring place by the trailing cable of towed body; When lash ship speedup traction, operating personal pulls unhook hawser, pull-out bearing pin, and under the elastic force effect of spring, unhook snap ring is separated, release towed body.
Beneficial effect: (1) utilizes the utility model to provide positive buoyancy for towed body, makes towed body keep positive buoyancy state at the water surface, can realize lash ship quiescence and hang towed body and enter water, avoids towed body simultaneously and to sink the risk at collision lash ship and the lower calm end.
(2) the utility model effectively reduce towed body risk of collision and the possibility at the end, protect the cable sector of winch, achieve towed body safe, reliably lay.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
See accompanying drawing 1, underwater towed-body distributor, it connects towed body, and provides positive buoyancy for towed body, and it comprises: buoyancy tube 1, unhook hawser 2 and unhook snap ring 3;
Buoyancy tube 1 is open column shape structure, and adopts glass-reinforced plastic material, and wall thickness is 4-5mm, withstand voltage 0.2MPa, length-diameter ratio >=11; Be provided with two symmetrical metal installation rings 5 at the outer wall of buoyancy tube 1, metal installation ring 5 is symmetrically distributed in vertical axis both sides, buoyancy tube 1 centre of buoyancy;
Unhook snap ring is two sectional type structure, and adopts stainless steel, and one end of every section of unhook snap ring 3 connects into an arcuate structure by bearing pin 4, and the other end is arranged on metal installation ring 5 place; One section of unhook snap ring 3 place is provided with spring 6 wherein, and spring 6 connects the metal installation ring 5 at this section of unhook snap ring 3 and this place;
Unhook hawser 2 is the bifilar elasticity hawser of Fiber Materials of diameter 4mm, sticks on the trailing cable of towed body, and one end connects bearing pin 4, and the other end is that free end is held by operating personal, is relaxed state time initial;
See accompanying drawing 2, before towed body enters water, unhook snap ring 3 place is connected to by the trailing cable of towed body, utilize towed body distributor to provide positive buoyancy for towed body, make towed body keep positive buoyancy state at the water surface, lash ship quiescence can be realized and hang towed body and enter water, avoid the risk that towed body sinks to colliding lash ship and the lower calm end simultaneously, after entering water, towed body is suspended in immediately below towed body distributor, spring 6 tensioning, and bearing pin 4 is subject to coupling mechanism force; When lash ship speedup traction, towed body is suspended in water in lift effect float downward stable state, the intermolecular forces at trailing cable and unhook snap ring 3 place reduces, the coupling mechanism force that bearing pin 4 is subject to disappears, operating personal pulls unhook hawser 2, and pull-out bearing pin 4, under the elastic force effect of spring 6, unhook snap ring 3 is separated, and release towed body also manually reclaims towed body distributor.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
