Underwater cutting releasing mechanism
Technical field
The present invention relates to a kind of relieving mechanism under water, particularly relate to underwater cutting releasing mechanism.
Background technology
By the buoy on the underwater cutting releasing mechanism release deep water platform, be a kind of method that depth float discharges.Generally speaking, underwater cutting releasing mechanism in a single day action can be realized two functions, the one, be used for discharging the underwater communication buoy, and the 2nd, cut off communication cable simultaneously, the buoy that is loaded with a large amount of marine environment data is emerged freely, finish the transmission of underwater information to the external world.The present invention develops on the basis of original underwater cutting releasing mechanism, structurally with action mechanism aspect brand-new improvement has been arranged.
Former underwater cutting releasing mechanism (national defence patent " auto-feeding device of water surface communication buoy ", the patent No.: 200410029326.3) structural representation is seen Fig. 5, it sees Fig. 6 to the restriction relation schematic diagram of buoy.Find this cutting relieving mechanism in actual the use, for itself, the cutting function aspect is very strong, and reliable in action is also very high.But there is certain hidden danger in the profile configuration aspects, as, this underwater cutting releasing mechanism is got angry and is moved, the cutter fast moving, though the cutter action is very normal, communication cable is cut off smoothly, also long-armed depression bar rotational restraint is removed simultaneously, it is freely rotated around self rotating shaft.Also this long-armed depression bar might twine with buoy bottom communication cable in the process of buoy come-up just.If this situation takes place, can make the communication buoy be difficult to emerge, so the communication buoy with underwater environment information and related data, just can not normally pass to the external world, this is fatal to product.Analyze reason, the reason that long-armed depression bar may take place to twine with the communication cable of communication buoy bottom is that long-armed depression bar produces vibration in the process that discharges suddenly, can impinge upon on the mounting platform, and bounce-back is returned fast.Because the initial ascent rate of communication buoy is smaller, the communication cable of communication buoy afterbody just might be wrapped on the long-armed depression bar, makes the communication buoy normally not emerge.Moreover, under the jolting of wave, there is this hidden danger too.
