Releasable sit bottom device for underwater profiler

Abstract

The invention discloses a releasable sit bottom device for an underwater profiler. The releasable sit bottom device comprises an end cover and a diversion cover, an altimeter is fixed on the outer side of the end cover, two axial through holes are formed in the end cover and are closely matched with shells of two electromagnets to achieve radial sealing, limiting stands are arranged at the two ends of each armature of the corresponding electromagnet, a spring is arranged between the limiting stand on one side and the shell of the corresponding electromagnet, two radial through holes are formed in the diversion cover, the spring end of each armature of the corresponding electromagnet corresponds to one radial through hole, the telescopic state of the armatures is controlled by controlling switching-on and switching-off of the electromagnets, and therefore control over a locked state of the end cover and the diversion cover is achieved; an empennage and a support frame are installed on the outer side of the diversion cover, and the support frame is fixed to a base support. According to the releasable sit bottom device for the underwater profiler, the sit bottom function of the profiler is achieved through the empennage, the support frame and the base support, and releasing of the sit bottom device of the profiler is conducted by controlling switching-on and switching-off of the electromagnets; the releasable sit bottom device for the underwater profiler is simple in structure, convenient to control and reliable in operation.

Description

Technical field [0001] The invention relates to a bottom sitting device for an underwater profiler, in particular to a releasable bottom sitting device for an underwater profiler. Background technique [0002] The bottom sitting function of the existing underwater profiler often uses negative buoyancy, simply placing the profiler on the seabed. However, the problem with this method is that the contact area between the profiler and the seabed is small, which is prone to dumping. On the other hand, the existing underwater profiler usually does not have a dumping device, and if the profiler is dangerous underwater, it will not be able to float. The few profilers with a throwing device are mostly throwing weights. The problem with this method is that if the bottom seat device is entangled by underwater objects, the profiler will not float. Moreover, the structure of the corresponding dumping device is relatively complicated. Summary of the invention [0003] The purpose of the pres...

However, the problem with this method is that the contact area between the profiler and the seabed is small, and it is prone to dumping

On the other hand, the existing underwater profiler usually does not have a dumping device, and if the profiler is dangerous underwater, it will not be able to float

For a few profilers with load-throwing devices, most of the corresponding load-throwing is weight-throwing. The problem with this method is: if the bottom-sitting device is entangled by underwater objects, the profiler will not be able to float

Moreover, the structure of the corresponding load throwing device is relatively complicated.
