Initially, the stopper 31 is inserted into the lock plate 2 to restrict the lock plate 2 on the lock body 1. Figures 1 to 17 ; The handle mechanism 4 is used for manually operating the disengagement of the lock plate 2. When the handle mechanism 4 is operated according to the unlocking action, it can drive the manual transmission assembly to drive the block 31 to withdraw from the lock plate 2 to achieve disengagement. Figures 1 to 8 ; The electronic mechanism 5 is used to automatically disengage the locking plate 2 when entering water. After detecting the entry into water, it triggers the automatic transmission component to drive the block 31 to withdraw from the locking plate 2 to achieve disengagement. Figures 9 to 17 .

[0033] The device integrates manual disengagement and automatic disengagement. When the pilot is unable to manually operate the handle mechanism 4 to disengage due to negligence after entering the water, the electronic mechanism 5 can also automatically disengage. When the electronic mechanism 5 fails and cannot automatically disengage after entering the water, the pilot can also manually operate the handle mechanism 4 to disengage, thereby improving safety redundancy. The key is that the handle mechanism 4 and the electronic mechanism 5 of the present application share a lock body 1 and a lock plate 2, and the manual transmission assembly and the automatic transmission assembly in the disengagement machine are not only coaxially installed, but also share a stopper 31 at the transmission end, and the transmission processes do not interfere with each other.

A flange 361 is provided on the upper end of the connector 36 and a protrusion 362 is provided on the outer side of the middle part. The flange 361 of the connector 36 is seated on the manual top ring 34, the protrusion 362 is matched on the cam of the automatic cam 35, and the lower end extends into the automatic cam 35. The upper end of the connecting shaft 37 can be axially slidably inserted into the handle mechanism 4, the middle part is provided with a shaft shoulder, and the lower end passes through the connector 36 and is connected to the block 31. The reset spring 38 is sleeved on the upper part of the connecting shaft 37 and presses the shaft shoulder on the connector 36. The handle mechanism 4 and the manual cam 32 are rotatably mounted on the lock body 1. The transmission scheme of the present application does not change the operating habits of pilots, is easily accepted by pilots, is convenient for replacing the current equipment, and has a good application prospect.

[0035] like Figures 5 to 8 As shown, when the handle mechanism 4 drives the manual cam 32 to rotate, the manual cam 32 drives the manual top ring 34 to push up through its own cam, the manual top ring 34 drives the connecting head 36 to push up through the flange 361, the connecting head 36 drives the connecting shaft 37 to push up through the shaft shoulder, the connecting shaft 37 compresses the reset spring 38 and drives the stopper 31 to move up and exit the locking plate 2; Figures 9 to 17 As shown, after the electronic mechanism 5 detects the entry into water, it triggers the driving push rod 332, the push rod 332 drives the push ring 33 to rotate, the push ring 33 drives the automatic cam 35 to rotate through the protrusion 331, the automatic cam 35 drives the connecting head 36 to push up through its own cam and protrusion 362, the connecting head 36 drives the connecting shaft 37 to push up through the shaft shoulder, the connecting shaft 37 compresses the reset spring 38 and drives the stopper 31 to move up and exit the locking plate 2.

[0036] In order to increase safety, in this embodiment, a safety component is added to the handle mechanism 4 to prevent misoperation and accidental separation of the lock piece 2: Figure 4As shown, the safety assembly includes a pair of buttons 41 located outside the handle mechanism 4 and a pair of safety pins 42 located inside the handle mechanism 4, the pair of safety pins 42 are located between the pair of buttons 41, one end of the safety pin 42 is fixed to the button 41 on one side, and the other end is connected to the button 41 on the other side through a spring 43, and the buttons 41 on both sides can be pressed simultaneously with one hand; when the buttons 41 on both sides are not pressed, the safety pin 42 hinders the axial movement of the manual top ring 34 and does not hinder the axial movement of the connector 36; when the buttons 41 on both sides are pressed at the same time, the safety pin 42 shifts and releases the axial obstruction to the manual top ring 34, when the buttons 41 on both sides are not pressed at the same time, manual release cannot be achieved even if the handle mechanism 4 is rotated, and manual release can only be achieved when the buttons 41 on both sides are pressed at the same time and the handle mechanism 4 is rotated, thereby avoiding misoperation and accidental disengagement of the lock plate 2, and whether the buttons 41 on both sides are pressed at the same time will not affect the realization of automatic release; as shown in FIG. Figure 4 As shown, the safety pin 42 has a variable cross-section along its own axial direction, and the two safety pins 42 are symmetrically arranged about the axis. When the buttons 41 on both sides are not pressed, the enlarged section near one end of the safety pin 42 hinders the axial movement of the manual top ring 34. When the buttons 41 on both sides are pressed at the same time, the narrowed section in the middle of the safety pin 42 avoids the manual top ring 34. In this way, the safety pins 42 on both sides are evenly stressed and the effect is better.

The electronic detection component includes a circuit board and electrodes. After the circuit board senses the conductivity of water through the electrodes, it determines that the object has entered water and excites the electric detonator. The electronic mechanism 5 is a relatively common mechanism currently available and is not the focus of this application.

[0039] In this embodiment, if Figures 1 to 3 As shown, the disengagement mechanism 3 and the handle mechanism 4 are installed on the upper middle side of the lock body 1, the handle mechanism 4 is located on the upper side of the disengagement mechanism 3 and outside the lock body 1, the lock plate 2 is fitted on one side of the lock body 1, and the electronic mechanism 5 is installed inside the other side of the lock body 1.
