A kind of submarine mechanical separation device
Technical field
The utility model relates to a kind of apparatus under water, specifically the underwater separator tool.
Background technology
Ocean be richly stored with living resources and mineral resources, and the mankind be unable to do without subsea equipment to the development and utilization of ocean.Due to the under-water operation circumstance complication, subsea equipment often faces various danger, think that it is very necessary that subsea equipment is equipped with safe-guard system.At present, the normal security strategy that adopts is, when equipment is caused danger under water, abandons the less important part of equipment, and makes pith rely on himself positive buoyancy to emerge.Usually, the connection between the subsea equipment each several part not only comprises mechanical connection, also comprises the connection of the electric parts such as feed cable, signal cable, as is equipped with the under-water operation equipment of underwater electric manipulator.Therefore, dynamo-electric kickoff mechanism has important using value in the safe-guard system of equipment under water under water.
Ocean engineering, that designs in the article of calendar year 2001 the 19th volume the 2nd periodical " " pathfinder " number Autonomous Underwater Vehicle is thrown the development of loading system " of stepping on abandons the ballast accumulator plant, and this device is only applicable to the heavier under-water operation equipment of load.
In addition, relating to the jettison system that the submarine mechanical body separates, is ZL200520097153.9 as the patent No., and name is called the patent document of " self-saving underwater operational releaser ", adopts motor and the double insurance of squib, realize reliably discharging, but volume is larger.Relating to the device that underwater cable separates, is ZL200720153627.6 as the patent No., and name is called the patent document of " underwater isolating electric coupler ", is the introduction of electric coupler itself, does not relate to pulling mechanism.
Summary of the invention
The purpose of this utility model is to provide a kind of submarine mechanical separation device of the mechanics reliable separation that realizes between minor equipment and visual plant.
The purpose of this utility model is achieved in that
A kind of submarine mechanical separation device of the utility model, it is characterized in that: comprise dynamical axis, cam, roller, mandrel, retracing spring, supporting plate, steel ball, hook, cam contacts with roller, roller is connected with mandrel by bearing pin, retracing spring one end is arranged on mandrel, the other end is pressed on supporting plate, the inboard of steel ball is pressed on mandrel, hook is blocked in the outer, and dynamical axis is connected with cam.
The utility model can also comprise:
1, described cam, roller, mandrel, retracing spring, supporting plate, steel ball, hook groups composition are from the unit, and described separative element has two at least, and the separative element all cam by separately connects dynamical axis.
Advantage of the present utility model is: mandrel can reset under the promotion of spring, and the socket sleeve that cable pulls mechanism can reset under the crank connecting link effect, can be repeatedly used.Increase a few cover mechanical separation mechanisms, adjust cam setting angle and camb contour, can realize the release successively of a plurality of loads, therefore, the utility model is various informative, is widely used.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the B-B cutaway view of Fig. 1
Fig. 3 is mechanical separating action schematic diagram;
Fig. 4 is mechanical separating resulting schematic diagram.
The specific embodiment
For example the utility model is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1~4, dynamical axis 2 is connected with cam 5 by key 4, and cam 5 contacts with roller 28, and roller 28 is connected with mandrel 25 by bearing pin 29, and mandrel 25 right-hand members are equipped with retracing spring 23, and spring 23 left ends are pressed on mandrel 25, and right-hand member is pressed on supporting plate 24.As shown in Figure 2, steel ball 31 inboards in sleeve 3 are pressed on mandrel 25, and hook 26 is blocked in the outer, and hook 26 tangles weight 27.Holding screw 30 is used for preventing the steel ball accidental.
Principle of work of the present utility model is:
As shown in Figure 3, cam 5 promotes mandrel 25 and moves to the right side end position, the motion to the inside under the pressure-acting of gravity and hook 26 of steel ball 31 this moment, when steel ball 31 is pressed on mandrel 25 again, lost application force to linking up with 26, weight 27 leaves equipment under the Action of Gravity Field of himself, separating resulting as shown in Figure 4.
The utility model can increase a few cover mechanical separation mechanisms again, adjust cam setting angle and camb contour, make subsea equipment discharge successively distinct device according to need of work, when arriving the appointment depth of invertigation as under-water operation equipment, abandon the download pouring weight, make implement stop dive, discharge localizer beacon when finding the detection of a target, being beneficial to lash ship positions target, when operation equipment sinks into danger, abandon pouring weight and make implement floating, when operation equipment emerges and when being not easy to reclaim, the floating of dishing out buoy is beneficial to reclaim.
The utility model also can have a plurality of mechanical separation mechanisms.
