Due to the positive buoyancy of the vehicle, three technicians are required to assist in pressing and straightening the vehicle at the head, tail and middle of the vehicle, so that the vehicle does not touch the water tank and is completely immersed in water. The three technicians need to maintain the downward pressure and straightening posture within 15 minutes to ensure that the vehicle does not swing or float to the surface before the air tightness test can be completed. This process is time-consuming and laborious, and the technicians need to switch hands back and forth to press down the vehicle and coordinate with each other, which is extremely inconvenient.

[0150] In summary, a more specific implementation method of the present invention is:

[0151] Before using the underwater vehicle airtightness inspection auxiliary device of the above-mentioned design structure, the various components need to be assembled and installed as spare parts.

[0152] The specific installation steps are:

[0153] Assembly of the locking mechanism 5: The locking handle 54 passes through the locking nut 53, and the position of the locking handle 54 is appropriately adjusted to prevent it from falling off when other components are installed; before welding the base component 1, the operator first assembles the locking mechanism 5 to the connecting rod 112 outside the support frame 11, and then the operator can assemble the base component 1;

[0154] Assembling the adjustment component 2: align the square through hole in the middle of the disc handle 22 with the square step above the handwheel screw 21, and fix them with flat washers and screws;

[0155] Assembly of the track wheel assembly 3: install the bearing 37 in the hollow circular groove at one end of the track wheel 31, and install the retaining ring 36 in the circular groove on one side of the bearing 37; install the bearing 37 and the retaining ring 36 on the other section of the track wheel 31 in the same way. When installing the retaining ring 37, ensure that the retaining ring 37 is completely embedded in the corresponding circular groove. Then, pass the cylindrical section of the track wheel shaft 32 through the two assembled sets of bearings 37, install the washer 35 and the locking piece 34 at the threaded hole position of the track wheel shaft 32 to ensure that the track wheel 31 is not stuck when turned by hand; finally, install a locking nut 33 on the full-thread screw 2324 of the track wheel shaft 32; place the base assembly 1 with locking mechanisms 5 on both sides on the operating platform, and then install the assembled track wheel assembly 3 on the track wheel connecting nut 13 of the base assembly 1 respectively, and adjust the position of the track wheel assembly 3 appropriately to prevent it from falling off;

[0156] Assembly of the claw 4: rotate the handwheel screw 21 of the adjustment component 2 clockwise through the fixing nut 14 of the base component 1, and properly adjust the length of the rotating screw to facilitate the installation of the claw 4; install the circular hole of the fixing block 44 of the claw 4 into the circular step of the handwheel screw 21, and then connect the circular end faces of the lower part of the handwheel screw 21 together through flat washers and screws to prevent the claw 4 from falling off. After the installation is completed, it can be used.

[0157] The specific steps are:

[0158] Before use, the operator rotates the adjustment component 2 so that the claw 4 is placed on the bottom plane of the adjustment component 2; rotates the locking handle 54 so that the distance between the rounded end faces of the two locking handles 54 is greater than the width of the water tank 6. Then, the operator places the utility model on one side of the upper plane of the water tank 6, and adjusts the track wheel assembly 3 so that the track wheel groove of the track wheel 31 is stuck above the corresponding side plate in the length direction of the water tank 6.

[0159] When in use, the operator first hangs the navigation body 7 in the water tank 6 filled with water, and the operator straightens the navigation body 7 to ensure that the axis of the navigation body 7 is parallel to the length direction of the water tank 6 and does not touch the water tank wall;

[0160] Then, the operator pushes the airtightness inspection auxiliary device of the navigation body to the middle position of the water tank 6, so that the claw 4 is placed at the center of gravity of the navigation body 7, and rotates the two locking handles 54 at the same time, so that the rounded end faces of the locking handles 54 are in contact with the outer wall of the water tank 6 and locked; then, the operator rotates the disc handle 22 clockwise, and then the disc handle 22 drives the handwheel screw 21 to move downward, so that the handwheel screw 21 drives the claw 4 connected thereto to gradually immerse the navigation body 7 as a whole under water; then, the navigation body 7 is kept in the water for 15 minutes, and the airtightness of the navigation body 7 can be inspected;

[0161] Finally, as time goes by, when the airtightness inspection is completed, the operator rotates the adjusting component 2 counterclockwise to make the navigation body 7 float to the surface with the claws 4, and then the operator continues to rotate the adjusting component 2 to make the claws 4 separate from the navigation body 7, and rotates the two locking handles 54 at the same time to release the lock; finally, the operator pushes the navigation body airtightness inspection auxiliary device to the side of the water tank 6, places the navigation body airtightness inspection auxiliary device on the side of the water tank 6, and moves the navigation body 7 away through the lifting equipment, and then the airtightness inspection of the next navigation body 7 can be carried out.
