Description
Technical field
The utility model relates to a kind of underwater ejection device, relates in particular to the electrochemical corrosion formula jettison system that a kind of oceanographic instrumentation is used.
Background technology
Along with the development of China's marine survey technology, especially the application of deep-sea instrument in the scientific research investigation work is more and more extensive for the hydrospace detection instrument.When the hydrospace detection instrument is worked under water, because operating environment is complicated, if when running into the emergency situation such as fault, power failure, can safe retrieving in order to ensure instrument, jettison system need to be set, and the weight that instrument is carried is thrown and is carried, and makes instrument utilize self buoyancy to rise to the sea.And also can by the throwing of pouring weight being carried promote the speed that oceanographic instrumentation sinks and floating is moved, save the time of under-water operation.
Throw at present that loading system comprises mainly that electrochemical corrosion, electromagnetic induction, hydraulic pressure are broken and explosive bolt this is several.
Electrochemical corrosion utilizes seawater itself as electrolyte solution, and molten fracture of wire material contacts with electrolyte solution, by the corrosion of electrode reaction generation.The electrochemical corrosion reaction is a kind of redox reaction.In reaction, metal loses electronics and oxidized, and its course of reaction is called the anode reaction process, and resultant of reaction is to enter the metallic ion in the medium or cover metallic oxide (or metal difficulty soluble salt) on the metal surface; Material in the medium is reduced from the metal surface electron gain, and its course of reaction is called the cathode reaction process.In the cathode reaction process, electron gain and the material that is reduced is called depolarizer traditionally.When even corrosion, the probability that carries out anode reaction and cathode reaction on the metal surface does not everywhere have marked difference, carries out the constantly random fluctuation of surface location of two kinds of reactions.If the metal surface has some zone mainly to carry out anode reaction, cathode reaction is mainly carried out in the remaining surface zone, claims that then the former is the positive column, and the latter is cathode region, and positive column and cathode region have formed corrosion cell.What cause directly that metallic material destroys is anode reaction, therefore often adopt external source or connect with the wire Metal Phase that protected metal and another cube electrode current potential is lower, occurs on the lower metal of current potential so that corrode.
It is to insert iron core in the middle of the o that the electromagnetic induction throwing is carried, because galvanomagnetic effect acquisition unshakable in one's determination magnetic force can hold the load-carrying piece, in case the magnetic force that cuts off the power supply will disappear, carries thereby realize throwing after switching on.
Hydraulic pressure is broken jettison system in normal operation, and the hydraulic oil in the hydraulic actuating cylinder does not have pressure, and it is an integral body that tie bolt conciliates with body that lift-off is connected.Carry in the situation that needs are thrown, in hydraulic actuating cylinder, inject high pressure oil by hydraulic gear, piston is moved to left, thereby break the predetermined cross-sectional in the tie bolt, so that separate lift-off and body disengaging.Tie bolt is the vital part of this kind throwing loading system, and can the long-pending design of the predetermined rupture cross section of tie bolt be to throw to carry the precondition that realize smoothly.
Explosive bolt likeness in form plain bolt, explosive and firing unit are equipped with in inside.During separation, explosive is detonated, and shearing lock is cut off or weakened groove along bolt to disconnect, and realizes two chorista releases.Explosive bolt is wide in variety, mainly contains open flume type, shear pin formula, steel-ball type explosive bolt and pollution-free explosive bolt etc., mainly is applicable to space industry.The advantage of this device is that load-carrying capacity is large, simple in structure, reliable operation, easy to use.Weak point is often to need a plurality of bolts, guarantees that whole bolts disconnect difficulty simultaneously larger.Also to guarantee in addition structure and equipment around remains did not injure when bolt disconnected, in case of necessity the protection structure should be set correspondingly, increase cost.

The utility model adopts electrochemical corrosion as the principle of work of jettison system, because seawater is the natural very strong electrolyte solution of electric conductivity, and electrochemical corrosion throws and carry simple for structurely, easily realizes, can reliable operation under complicated sea situation.Jettison system is in case of emergency expeditious measures normally, this just require to throw loading system can make the observation instrument body and throw realize between the loads fast, failure-free separates.Jettison system should be tried one's best simple compact, easy for installation and be easy to and be safeguarded.
Throwing is carried a motor unit and is comprised set casing, throws the load-carrying piece, and cathode wire is captiveed joint with set casing by the cathode lock jack panel, and positive wire is captiveed joint with set casing by the Anode lock jack panel, and positive wire is connected with throwing load-carrying piece by metal filament.
Be provided with the corrosion storehouse in the set casing, the lower ending opening in corrosion storehouse is thrown the load-carrying piece and is arranged in the corrosion storehouse.
Be provided with spring between set casing and the throwing load-carrying piece.
Described cathode wire links to each other with power supply with described positive wire, can conducting liquid in the described corrosion cabin, so seawater serves as electrolyte solution when power supply is switched on, described metal filament contacts with electrolyte solution, described metal filament is with the anode reaction in the electrochemical corrosion reaction, cause molten disconnectedly with oxidized, the throwing of finishing described throwing load-carrying piece is carried.
Employing the utility model has the advantages that:
The utility model device is easy, and easily operation is carried additionally upthrow load-carrying piece before only needing to use at every turn and got final product;
Throwing load-carrying piece quality can independently select, and can select quality at the throwing load-carrying piece of 0-10 kilogram according to particular cases such as different subsea equipments;
Adopt the electrochemical corrosion principle to throw and carry, throw the process of carrying rapid, the spring of assembling guarantee to throw carry after the release of pouring weight, guarantee to throw carry reliable rapidly;
The predeterminable program of jettison system when the subsea equipment degree of depth during greater than a certain depth value, is thrown and is carried a control unit and automatically release order and throw the load-carrying piece, realizes the safe retrieving of subsea equipment.
