Description
Technical field
The utility model relates to a kind of saturation diving moon pool of wave absorption type, belongs to the diving moon pool technical field of boats and ships.
Background technology
Saturation diving is a kind of being applicable under large depth conditions, and diver is directly exposed to the diving mode of carrying out long-time under-water operation under water.In accordance with international practices, when the work drowned degree of depth surpasses 120 meters, the time surpasses 1 hour, is all generally to adopt saturation diving.
Diving bell is a kind of diver's dive means of delivery.Diving bell is delivered to respective depth under water the diver in high pressure saturation conditions, and diver's deliver from vault is directly exposed to touring diving under water and carries out operation, during rest, by diving bell, diver is sent back in the high pressure habitation module on surface ship.
The diving bell of saturation diving implement system is by draw off gear, to hang diving bell to pass through up and down special use " diving moon pool " dive and recovery, ripples slamming and vertical suction vent plug in diving moon pool can be to producing great shock wave in the diving bell under hyperbaric environment, the safety of diver in diving bell body and psychology are caused to direct impact, also can cause damage to diving bell equipment and annex.Eliminate the interior ripples of diving moon pool most important to guaranteeing safe dive and the water outlet of diving bell for this reason.
Summary of the invention
The purpose of this utility model is reduce and eliminate ripples in diving moon pool, thereby improves the safety of diving bell dive and water outlet.
The utility model relates to the diving bell Special diving moon pool wave absorption technology of saturation diving operation, and the utility model is specifically taked following technical scheme:
A saturation diving moon pool for wave absorption type, described saturation diving moon pool surrounding sidewall is provided with the interlayer of hollow outward, and interlayer comprises horizontal baffle, vertical clapboard; Described horizontal baffle and vertical clapboard are divided into a plurality of spaces by described interlayer; The perforate respectively of described horizontal baffle and vertical clapboard.
Due at sea, the water surface of saturation diving moon pool has ripples, (the rolling of swaying along with boats and ships, ancestor shakes, heave), particularly at sea under severe sea conditions, swaying more sharply of boats and ships, the water surface that makes to dive under water in moon pool is more not steady, the ripples wave height of the water surface can be larger, if do not take technical measures, is greater than sometimes marine wave height, to pass through up and down diving moon pool at diving bell, cause more rugged environment condition, the slamming phenomenon that in diving moon pool, the ripples of motion produce diving bell will be more seriously.During saturation diving operation, diver in diving bell is under the desired hyperbaric environment of diving depth, ripples slamming and vertical suction vent plug in diving moon pool can be to producing great shock wave in the diving bell under hyperbaric environment, the safety of diver in diving bell body and psychology are caused to direct impact, diving bell equipment and annex are caused to damage, therefore eliminate the interior ripples of diving moon pool most important to guaranteeing safe dive and the water outlet of diving bell.
The technical program, by hollow sandwich being set at diving moon pool surrounding sidewall outward, in horizontal baffle and the vertical clapboard perforate respectively of interlayer, has formed buffering to ripples simultaneously, has reduced the fluctuating range of ripples; The effect of perforate is also: form between the additional circulation passage and current buffer zone of current and air, eliminate the vertical suction vent plug phenomenon producing when diving bell passes through diving moon pool up and down, eliminate the slamming of vertical suction vent plug to diving bell in diving moon pool.
Further, described saturation diving moon pool is provided with scavenger system, and the main tracheae 2 of described scavenger system is positioned at diving moon pool under water in a certain plane, on main tracheae 2, is evenly arranged air blowing short tube 1, and air blowing short tube 1 is vertical with main tracheae 2, and blowing direction is inside; Air blowing short tube 1 mouth of pipe is positioned at described interlayer.Air blowing short tube sprays into pressurized air by the aperture opened on diving moon pool leg in moon pool inner water, to form bubble damping layer, air blowing short tube takes to weld the close property of cushion block be threaded to keep the to dive under water water tightness of moon pool leg, level is installed air blowing short tube, and short tube does not stretch in diving moon pool in order to avoid damaged in collision and safety when affecting diving bell and passing through up and down diving moon pool.
Further, described saturation diving moon pool is rectangular, and described horizontal baffle, vertical clapboard are all rectangular.Simple in structure, be convenient to arrange and install.
Further, on described horizontal baffle, offer circular hole, the height of described vertical clapboard is greater than width, offers vertical elliptical aperture on vertical clapboard.Simple in structure, and through overtesting, reduce ripples and eliminate the works very well that diving bell passes through the vertical suction vent plug phenomenon producing while diving under water moon pool up and down.
Further, the position on every layer of deck of the corresponding hull of saturation diving moon pool is equipped with deck dividing plate, and described deck dividing plate has diving bell whereabouts centre hole, described diving bell whereabouts centre hole and the profiling of diving bell external diameter, and its aperture is slightly larger than the external diameter of diving bell; Except the dividing plate of first floor deck, on all the other deck dividing plates, evenly offer circular hole.Strengthen reducing the effect of ripples, and be convenient to the lower water of diving bell.
The beneficial effects of the utility model are:
1) eliminate or reduced ripples in diving moon pool, thus the safety of raising diving bell dive and water outlet.
2) overcome the vertical suction vent plug phenomenon producing when diving bell passes through diving moon pool up and down, eliminated the technical difficulty of vertical suction vent plug to diving bell slamming in diving moon pool.
3) adopt scavenger system to form the technological means such as bubble damping layer simultaneously, reached good safe effect.
