Description
Technical field
The present invention relates to underwater units, particularly relate to a kind of device realizing underwater structure and be separated.
Background technology
Along with the mankind's deepening continuously to deep-sea exploration, ocean environment observation subsurface buoy lay the degree of depth also in continuous increase.Deep-sea subsurface buoy carries the underwater buoy of multiple observation instrument, is arranged in the water of deep-sea, throws in and anchored in seabed by anchor system device from the water surface.Multiple Marine Environmental Elements measured by the observation instrument that deep-sea subsurface buoy is carried.
Deep-sea subsurface buoy own wt may reach more than 1 ton, and directly throw in from the water surface if equipment does not add protection, in water in decline process, its falling speed will constantly increase.In this case, the impulsive force that formed after directly touching seabed of subsurface buoy is by likely on subsurface buoy and the impact of damaging property of observation instrument of carrying.
When laying for avoiding subsurface buoy, in water, descending speed is too fast, normally in subsurface buoy, increases ball float, promotes overall buoyancy.But this brings again other problem, after ball float sinks to seabed with subsurface buoy, its buoyancy effect attitude stability of subsurface buoy, after running into side direction ocean current, easily drift is from original position, and the corresponding relation in take off data and geographic position caused confusion.For this reason, between ball float and subsurface buoy, increase kickoff mechanism, can ensure that subsurface buoy falling speed is unlikely to excessive on the one hand, be separated with ball float after subsurface buoy also can be made on the other hand to arrive seabed, do not affect subsurface buoy mode of operation.At present, conventional kickoff mechanism has two kinds: one is acoustic control device, sends specific audible signal control setup action realize freeing by water surface ship; Another kind is the kickoff mechanism of band pressure sensor, frees voluntarily after reaching certain depth.
But above two kinds of kickoff mechanisms all need built-in circuit, battery and sensor, and cost is higher, at sea during operation once lose, lose larger.And the accidental error of circuit and sensor connection signal all can be laid and brings larger infringement to freeing operation and deep sea diving target.
Summary of the invention
For deep-sea subsurface buoy and the problem that lays between ball float existing for kickoff mechanism of prior art, the present invention is proposed a kind of new mechanical type underwater fixed depth kickoff mechanism, to the outer sleeve of groove and circular hole and inner sleeve be set respectively and groove is set and sealing slide block with water depth pressure movement is combined by ball, the connection of the subsurface buoy realizing connecting outer sleeve and the ball float connecting inner sleeve be separated, ball float can be realized be separated with freeing within the scope of subsurface buoy under water certain depth without the need to relying on sensor and circuit.
The mechanical type underwater fixed depth kickoff mechanism main body that the present invention relates to is cylindrical structural, comprise outer sleeve, inner sleeve, sealing slide block and spring, inner sleeve bottom is inserted in outer sleeve top, the internal diameter of outer sleeve and the external diameter of inner sleeve form free-running fit, sealing slide block and spring are placed in inner sleeve, sealing slide block is cylinder, and spring is positioned at sealing slide block top.Inner sleeve upper end connects the ball float peg hanging ball float, and the lower end of outer sleeve connects suspension deep sea diving target instrument peg.
Inner sleeve top is provided with tapped bore, and the screw thread of tapped bore is corresponding with the screw thread on the screw rod of ball float peg bottom, makes ball float peg screw in inner sleeve, infusion epoxy resin in the tapped bore of inner sleeve top.
Bottom inner sleeve, permeable hole is set, with seawater conducting, makes the sealing slide block induction ambient pressure being positioned at inner sleeve.Sealing slide block top arranges O type circle.
Inner sleeve arranges circular hole, the equal altitudes arrangement at equal intervals of multiple circular hole.Put into ball in circular hole, the diameter of circular hole is slightly larger than ball diameter, and the radius of ball is equal with inner sleeve wall thickness.
Outer sleeve inwall and sealing slide block lower outside arrange groove respectively, and number of recesses is equal with the circular hole quantity that inner sleeve is arranged respectively, and multiple groove is sleeve lining and the equal altitudes arrangement at equal intervals of sealing slide block lower outside outside respectively.Recess width is more bigger than ball diameter, and depth of groove is consistent with ball bearing radius.
The lower end of outer sleeve is fixed together by binding bolt with suspension deep sea diving target instrument peg.
This device in use, first rotate ball float peg, withstand the spring in inner sleeve, make spring form certain elastic force and sealing slide block is headed into the bottom of inner sleeve, infusion epoxy resin between the top of inner sleeve and ball float peg again, rotate when preventing ball float peg from using and change elastic force, also play the effect of sealing simultaneously.Then use hawser to be connected ball float and subsurface buoy respectively on ball float peg with instrument peg, ball is in the circular hole of inner sleeve and the groove of outer sleeve, and ball float and subsurface buoy are connected by the locking of inner sleeve and outer sleeve.Then, subsurface buoy input is carried out in selected marine site, after equipment throws in water, along with instrument declines, the sea pressure that sealing slider bottom is subject to increases gradually, after pressure exceedes spring force, move on sealing slide block starts, when the groove of sealing slide block moves to ball position, ball is subject to upwards downward with the outer sleeve shearing force of inner sleeve, due to the profile that ball is spherical, ball starts to move in the groove of sealing slide block, when being squeezed into completely in the groove sealing slide block, no longer lock between inner sleeve with outer sleeve and be separated, subsurface buoy continues to decline, ball float starts to rise, free operation to complete.
When the degree of depth is freed in needs adjustment, only need to rotate ball float peg, spring force is changed, the ambient pressure needed for corresponding sealing slide block slides will change, and can realize in the degree of depth that different pressures is corresponding freeing.
The mechanical type underwater fixed depth kickoff mechanism that the present invention relates to utilizes the combination of mechanical part, the connection realizing subsurface buoy and ball float be separated, structure is simple, cheap, and stable performance is easy to use.
