Seal casinghousing 4 has the cylindrical shape with boss, and center has through hole.The upper and lower side of boss of seal casinghousing 4 arranges external screw thread, connects the lower end of pilot sleeve 2 by boss upside external screw thread, by the downside external screw thread of boss, seal casinghousing 4 is installed on measuring instrument shell 5.On the boss lower surface of seal casinghousing 4, be furnished with seal groove, end-face seal ring 12 is set in seal groove, end-face seal ring 12 is realized the watertight in seal casinghousing outside.Seal casinghousing 4 central through holes are divided into two sections, and epimere internal diameter is greater than hypomere internal diameter, and seal casinghousing 4 epimere through-hole walls arrange semi-circular recesses.
Stop collar 3 is cylinder-like structure, is arranged in seal casinghousing 4 epimere through holes.On the barrel at stop collar 3 middle parts, horizontal direction evenly arranges 2～3 perforates that steel ball 11 is installed, and the position of perforate is corresponding with the semi-circular recesses of seal casinghousing 4, and steel ball 11 is positioned at the perforate of seal casinghousing 4 semi-circular recesses and stop collar 3.Between the epimere through hole internal diameter of the external diameter of stop collar 3 and seal casinghousing 4, adopt matched in clearance, keep having between the lower surface of stop collar 3 and the lower surface of seal casinghousing 4 epimere through holes the gap of 0.3～0.5mm.
The interior installation release shaft 9 of stop collar 3, stop collar 3 arranges sliding axle 6 below, and sliding axle 6 is arranged in seal casinghousing 4 hypomere through holes.Between sliding axle 6 and seal casinghousing 4, cylinder sealing ring 13 is set, realizes the watertight of seal casinghousing 4 central through holes, guarantee sliding axle 6 sealing effectiveness in whole sliding strokes in seal casinghousing 4.
Release shaft 9 is the cylinder with boss, and spring 10 is installed on boss top, and release shaft 9 is pressed on upper spring 10 in stop collar 3.The semi-circular recesses of seal casinghousing 4 matches with the boss of release shaft 9, by steel ball 11, completes the axial location in seal casinghousing 4 to stop collar 3.The boss lower diameter of release shaft 9 diminishes, and after moving upward, provides the space that holds steel ball 11 for release shaft 9, and steel ball 11 can be pushed into stop collar 3 inside under external force, thereby can realize the release of stop collar 3 axial location.
Release shaft 9 tops pass stop collar 3, and its top is connected with and drives stay cord 1, and the driving stay cord 1 of Connection Release axle 9 passes pilot sleeve 2.When throwing in measuring instrument, drive stay cord 1 to connect parachute.
Pilot sleeve 2 is cylindric, be arranged on the top of seal casinghousing 4, pilot sleeve 2 endoporus are up-small and down-big bellmouth, and lower end is provided with internal thread, upper end outer rim is rounding, can make to act on from different directions the pulling force driving on stay cord 1 and effectively pass to release shaft 9.Pilot sleeve 2 is threaded and is fixed on seal casinghousing 4 tops by lower end, after driving stay cord 1 is fixed by the aperture of release shaft 9 upper ends, passes pilot sleeve 2.
Sliding axle 6, for the middle cylinder that has boss, is placed in locking sleeve 7, and sliding axle 6 boss upside shaft parts are arranged in seal casinghousing 4 hypomere through holes.On boss upside shaft part, be processed with the groove for axial seal, axial sealing ring 13 is installed in groove.
Sliding axle 6 is upwards pressed on stop collar 3 lower surfaces under lower spring 8 effects.Because stop collar 3 has completed axial location in seal casinghousing 4, sliding axle 6 completes axial location and fixes under the acting in conjunction of stop collar 3, lower spring 8 and locking sleeve 7.Meanwhile, release shaft 9 is pressed on the upper surface of sliding axle 6 under the effect of upper spring 10, and the axial location that completes release shaft 9 under the acting in conjunction of stop collar 3, upper spring 10 and sliding axle 6 is fixed.Sliding axle 6 lower ends pass the through hole at locking sleeve 7 bottom face centers, and the reed of self-lock switch 15 is compressed.
Self-lock switch 15 is a kind of by the switch of reed control, is fixedly installed to the flange outer sides end face of locking sleeve 7 by screw 14, and two contacts of self-lock switch 15 are wired to respectively in the power supply circuits of measuring instrument.Sliding axle 6 bottom shaft parts stretch out and compress reed from locking sleeve 7, keep self-lock switch 15 in off-state.By compress and decontrol reed disconnect with closure state between change, realize the disconnection of circuit and the control of connection.
This device cooperatively interacts by the groove on the boss on release shaft 9, seal casinghousing 4 and steel ball 11 on the whole, realizes the axial restraint of stop collar 3.Then using stop collar 3 as supporting, utilize the pretension thrust of lower spring 8, complete the axial restraint of sliding axle 6; Using sliding axle 6 as supporting, utilize the pretension thrust of upper spring 10, complete the axial restraint of release shaft 9.Final sliding axle 6 is pressed abd fixed on normally open position by the reed of self-lock switch 15.
Once driving stay cord 1 to be subject to certain external force pulls, release shaft 9 moves upward, boss leaves locked position of coupler, effect downslide moving axis 6 at lower spring 8 upwards promotes stop collar 3, steel ball 11 is pushed out the groove on seal casinghousing 4 after having lost release shaft 9 spacing, thereby stop collar 3 has lost axial fixing, driven stay cord 1 to drive and departed from seal casinghousing 4.Sliding axle 6 continues to move upward and is finally pressed on the lower surface of seal casinghousing 4 simultaneously, in the complete retraction locking sleeve 7 in bottom of sliding axle 6, the reed of self-lock switch 15 is upspring losing after spacing, switch closure, connect power supply circuits, thereby realized upper Electricity Functional.And sliding axle 6 will continue to be pressed on seal casinghousing 4 under lower spring 8 effects, self-lock switch 15 continues to keep normally off, guarantees the lasting connection of power supply circuits.
Before and after electrifying device action, end-face seal ring 12, cylinder sealing ring 13 can both continue to keep sealing function, the measuring instrument that guarantees to use this device lasting sealing in water.
