The submersible locking mechanism suitable for the base station type operating system mainly solves the problems of locking and unlocking of the submersible in the base station, so that the use requirements of reliable locking and frequent access of the submersible in the base station are met. Referring now to fig. 1-7, the structure and method of operation of a submersible locking mechanism 100 according to a preferred embodiment of the present invention is specifically illustrated.
Specifically, as shown in fig. 1 and 2, the submersible locking mechanism 100 includes:
the submersible vehicle comprises a base 10, wherein two clamping rings 101 with through grooves 102 are formed in the base 10 in an extending mode, and an inserting groove 103 is formed between the two clamping rings 101 and used for inserting a locking ring 201 of a submersible vehicle 200;
the locking tongue 20 is fixed on the clamping ring 101 and can move up and down in the direction perpendicular to the locking ring 201 of the submersible vehicle 200 in the through grooves 102 of the two clamping rings 101, so that the locking ring 201 of the submersible vehicle 200 can be unlocked and locked;
a bolt driving lever 30, wherein the bolt driving lever 30 is connected to the bolt 20 and is used for linking the bolt 20 to move up and down; and
and the driving mechanism 40, wherein the driving mechanism 40 includes a driving motor 41 and a cam 42 linked with the driving motor 41, and the cam 42 is disposed below the bolt driving lever 30 and is used for driving the bolt driving lever 30 to move up and down.

That is, when the cam 42 rotates such that the second end 422 is gradually spaced away from the bolt driving lever 30, the cam 42 no longer provides a supporting force to the bolt driving lever 30, so that the bolt driving lever 30 and the bolt 20 can move downward by its own weight, thereby achieving locking of the locking bolt 20 to the locking ring 201 of the submersible vehicle 200 inserted into the insertion slot 103; when the cam 42 rotates to gradually jack up the second end 422 against the bolt actuating lever 30, the bolt actuating lever 30 can be jacked up by the second end 422 to move upward, so that the bolt 20 is interlocked to move upward, thereby unlocking the locking ring 201 of the submersible vehicle 200 inserted into the slot 103 by the bolt 20.
It can be understood that the submersible locking mechanism 100 of the present invention is particularly suitable for a base station type operation system, belongs to an underwater locking mechanism, and can avoid the situation that the submersible falls off accidentally in the process of deployment and recovery, and the submersible locking mechanism 100 is fixed in the base station through the base 10, so that reliable unlocking and locking actions of the unmanned submersible can be realized.

In particular, in this preferred embodiment of the present invention, the submersible vehicle locking mechanism 100 includes two of the guide rails 60, two of the guide rails 60 are vertically disposed on the sliding bearing 70, that is, two of the guide rails 60 are parallel to the latch tongue 20, it is understood that the up-and-down movement of the latch tongue 20 is supported by two of the vertical guide rails 60, the movement resistance is reduced by the sliding bearing 70, the locking and unlocking of the submersible vehicle 200 by the latch tongue 20 can be facilitated, and the locking force direction of the submersible vehicle locking mechanism 100 is vertically distributed with respect to the movement direction of the latch tongue 20, the locking capability of the submersible vehicle locking mechanism 100 is ensured by the strength of the guide rails 60 and the latch tongue 20, regardless of the driving motor 41 at the driving end, thereby ensuring the magnitude of the locking force and reducing the requirement for the driving force, the weight and size of the submersible locking mechanism 100 itself can be advantageously reduced so that the submersible locking mechanism 100 can meet the requirements of a base station type operation system.
Furthermore, the locking mechanism 100 further includes an elastic member 80, wherein the elastic member 80 is sleeved on the guide rail 60 and two ends of the elastic member 80 respectively support against the sliding bearing 70 and the guide rail supporting seat 50, so as to increase the restoring force for the locking bolt 20.
It should be noted that the locking mechanism 100 of the submersible vehicle comprises two elastic members 80, the elastic members 80 are sleeved on the corresponding guide rails 60, one end of the latch bolt driving lever 30 is supported on the cam 42, and the other end of the latch bolt driving lever passes through the two guide rails 60 and is vertically connected to the latch bolt 20.
It will be appreciated that in order to further enhance the flexibility and reliability of locking and unlocking the submersible vehicle locking mechanism 100, the present invention adds the elastic member 80 in such a manner that the elastic member 80 can be compressed to store potential energy when the latch bolt 20 moves the sliding bearing 70 upward, and when the cam 42 no longer provides a supporting force for the latch bolt driving lever 30, the elastic member 80 releases the potential energy to allow the latch bolt 20 to rapidly fall down to lock the locking ring 201 of the submersible vehicle 200 inserted into the insertion groove 103. That is, the elastic member 80 functions to increase the force for returning the locking bolt 20, so that the locking bolt 20 can perform a locking operation reliably.
It should be noted that the elastic member 80 may be a spring or a leaf spring.
Further, it is worth mentioning that the base 10 comprises a first support plate 11, a second support plate 12 disposed above the first support plate 11 at an interval, and a plurality of supports 13 for supporting and connecting the first support plate 11 and the second support plate 12, wherein two of the clasps 101 extend from the first support plate 11 and the second support plate 12, respectively.

It is worth mentioning that the drive mechanism 40 is provided with the sealing ring 45 for waterproofing, since the submersible locking mechanism 100 is operated under water, which is a problem in securing waterproofing.
Specifically, when the drive motor 41 is rotated to rotate the cam 42 in conjunction therewith, the angle sensor 43 is used to detect the angle of rotation of the cam 42, thereby determining whether the position of rotation of the cam 42 causes the latch bolt driving lever 30 to move up to the uppermost position or down to the lowermost position, thereby determining the corresponding position of the latch bolt 20, thereby completing the determination of the locked state and unlocked state between the vehicle locking mechanism 100 and the vehicle 200.
It will be appreciated that the actuation of the cam 42 of the drive mechanism 40 is effected by a single drive motor 41, with feedback control being effected by the angle sensor 43 integrated within the drive motor 41, facilitating accurate locking and unlocking operation of the submersible locking mechanism 100.
It should be noted that the driving motor 41 may be any one of a dc motor, an ac motor, a servo motor, and a stepping motor, but the present invention is not limited thereto, and preferably, the driving motor 41 is a dc motor.
Further, the driving mechanism 40 further includes a housing 46, the housing 46 has a first housing 461 and a second housing 462 connected to the first housing 461, a diameter of the second housing 462 is larger than a diameter of the first housing 461, the driving motor 41 is disposed in the first housing 461, and the angle sensor 43, the driving mechanism bearing 44 and the sealing ring 45 are disposed in the second housing 462.

As shown in fig. 6 and 7, the locked state and the unlocked state (or state to be locked) between the submersible locking mechanism 100 and the submersible 200 are illustrated.
Specifically, the locking operation process of the submersible locking mechanism 100 is as follows: before the locking operation of the submersible vehicle locking mechanism 100, the driving motor 41 of the driving mechanism 40 is started to rotate, and the latch bolt 20 is lowered to the lowest position. When the submersible vehicle 200 enters the base station, the locking ring 201 of the submersible vehicle 200 is inserted into the slot 103 in a manner of contacting the position of the circular arc inclined surface 21 at the bottom of the locking tongue 20, the locking tongue 20 is pushed by the locking ring 201 to move upwards during the insertion of the locking ring 201 of the submersible vehicle 200, and after the locking ring 201 is completely inserted into the slot 103, the locking tongue 20 falls down and resets under the action of the self-gravity of the locking tongue 20 and the potential energy released by the elastic member 80, and the submersible vehicle 200 is locked, as shown in fig. 6.
The unlocking operation process of the submersible locking mechanism 100 comprises the following steps: when the submersible vehicle 200 is going to leave the base station, the cam 42 is driven to rotate by means of the driving motor 41 of the driving mechanism 40, and the bolt driving rod 30 is jacked up, so that the bolt 20 moves upwards, in the process, the driving mechanism 40 detects the rotating angle of the cam 42 through the angle sensor 43, so that the position of the bolt 20 moving upwards is determined, and the submersible vehicle 200 is unlocked when the bolt 20 moves upwards to the highest position, and the submersible vehicle 200 can be pulled out from the slot 103, as shown in fig. 7.
That is, the present invention also provides in another aspect a method of operating a submersible locking mechanism 100, comprising the locking operation:

The direction of the locking force of the submersible locking mechanism 100 to the submersible 200 is vertically distributed with the moving direction of the bolt 20, the locking capacity of the submersible locking mechanism 100 is ensured by the sliding bearing 70 and the bolt 20, and is independent of the driving motor 41 at the driving end, so that the locking force can be ensured, the requirement on the driving force is reduced, the weight and the size of the mechanism are reduced, and the angle sensor 43 is integrated in the driving motor 41, so that the submersible locking mechanism 100 is compact in integral structure, small in size and light in weight, and more scientific instruments can be carried by a base station type operating system.
