When the underwater separation device is thrown into water for operation, water flow enters the cavity through the first communication part 240, and further water flow pressure is applied to the insertion part 422 on the sliding part 420, because the sliding part 420 is simultaneously acted by the elastic force of the second elastic part 500, when the water pressure generated by the water flow is small, the water pressure is smaller than the sum of the pressure of the sealing cavity 430, the elastic force of the second elastic part 500, the friction force between the annular sealing ring and the locking shell 410 and the friction forces between the insertion part 422 and the first separation body 100 and the second separation body 200, the sliding part 420 does not act, and when the water pressure generated by the water flow is larger than the sum of the pressure of the sealing cavity 430, the acting force of the second elastic part 500 on the sliding part 420, the friction force between the annular sealing ring and the locking shell 410 and the friction forces between the insertion part 422 and the first separation body 100 and the second separation body 200, the sliding part 420 is pushed to move towards the sealing cavity 430, at this time, the insertion portion 422 also moves toward the sealed cavity 430 along with the slider 420, and the insertion portion 422 is separated from the first locking portion 110 and the second locking portion 210, thereby unlocking the first separation body 100 and the second separation body 200.
Since the first elastic member 300 is disposed between the first separation body 100 and the second separation body 200, when the insertion portion 422 locks the first separation body 100 and the second separation body 200, the first elastic member 300 between the first separation body 100 and the second separation body 200 is in a compressed state, and when the first separation body 100 and the second separation body 200 are unlocked, the first elastic member 300 ejects the first separation body 100 and the second separation body 200 to both sides by an elastic force, so as to separate the first separation body 100 and the second separation body 200.
Because the assembly direction of the third separating body 920 and the fourth separating body 930 is the same as the separation direction of the first separating body 100 and the second separating body 200, when the first separating body 100 and the second separating body 200 are separated, the first clamping protrusion 140 and the second clamping protrusion 250 above the first separating body are correspondingly separated from the first annular clamping groove 922 and the second annular clamping groove 932, so that the third separating body 920 and the fourth separating body 930 are synchronously separated.
The underwater separation device in the embodiment can realize automatic separation through the pressure action of water flow after sinking to a certain depth during separation, can realize automatic separation of the device without the assistance of other energy sources, and reduces the consumption of energy sources;
when the underwater separation device in the embodiment is used for separation, the first separation body 100, the second separation body 200, the third separation body 920 and the fourth separation body 930 can be separated simultaneously, and the separation effect is good.

Specifically, in the underwater separation device in this embodiment, when the underwater separation device is in a non-operating state, the locking device 400 ejects the insertion portion 422 of the sliding member 420 under the action of the second elastic member 500, the insertion portion 422 is inserted into the first locking portion 110 and the second locking portion 210 to achieve locking and fixing of the first separation body 100 and the second separation body 200, at this time, the first separation body 100 and the second separation body 200 cannot move and rotate relatively, and the third separation body 920 and the fourth separation body 930 are clamped on the first separation body 100 and the second separation body 200.
When the underwater separation device is thrown into water for operation, water flow enters the cavity through the first communicating part 240, and further applies water flow pressure to the inserting part 422 on the sliding part 420, when the water pressure generated by the water flow is smaller than the sum of the pressure of the sealing cavity 430, the elastic force of the second elastic component 500, the friction force between the annular sealing ring and the locking shell 410 and the friction forces between the inserting part 422 and the first and second separation bodies 100 and 200, the sliding part 420 does not act, when the water pressure generated by the water flow is larger than the sum of the pressure of the sealing cavity 430, the acting force of the second elastic component 500, the friction force between the annular sealing ring and the locking shell 410 and the friction forces between the inserting part 422 and the first and second separation bodies 100 and 200, the sliding part 420 is pushed to move towards the sealing cavity 430, and at the moment, the inserting part 422 moves towards the sealing cavity 430 side along with the sliding part 420, the inserting portion 422 is separated from the first locking portion 110 and the second locking portion 210, so that the first separation body 100 and the second separation body 200 are separated in a first direction, and the third separation body 920 is separated from the first separation body 100 and the second separation body 200 in a clamping assembling direction, and the fourth separation body 930 is separated from the first separation body 100 and the second separation body 200 in a clamping assembling direction, which are the same as the first direction. When the first separation body 100 and the second separation body 200 are separated, the third separation body 920 and the fourth separation body 930 are also separated correspondingly, and the specific separation method is the same as that in the first embodiment, which is not described herein again.
The first direction in this embodiment may be a left-right direction, and the corresponding third separation body 920 is assembled with the first separation body 100 and the second separation body 200 in a left-right direction, so as to ensure that the first separation body 100 and the second separation body 200 can be separated from the third separation body 920 at the same time when separated, thereby achieving the effect of simultaneously separating a plurality of separation bodies. Meanwhile, the fourth separation body 930 is also separated from the first separation body 100 and the second separation body 200, so that the four components are separated at the same time, and the separation efficiency is higher.
