[0002] In the field of modern marine engineering, ship technology and underwater detection, sonar systems play a crucial role. Sonar equipment is widely used in various underwater vehicles or marine facilities such as ships, submarines and underwater operation platforms. However, sonar devices are often used in complex and harsh underwater environments for a long time. In order to ensure the normal operation of sonar equipment, sonar equipment needs to be regularly inspected and repaired or replaced.

9. The method of using the integrated device for sonar repair and replacement from inside the ship's cabin as described in claim 3, characterized in that, This includes the disassembly and installation of the sonar (9); the disassembly steps of the sonar (9) are as follows: First, remove the sealing cover (10); Second, start the lifting cylinder (3), which drives the support sleeve (2) to move upward, sonar (9) passes through the first isolation block (604) and enters the inner side of the first isolation block (604); until the support sleeve (2) presses the contact sensor (5), the support sleeve (2) stops moving, and at the same time the drive cylinder (605) starts, and the first isolation block (604) closes; Third, make the sonar (9) move upward inside the support sleeve (2), when the sonar (9) moves up to the stop bar ( After being blocked (802), the sonar (9) passes through the second isolation block (702) and enters the inner side of the second isolation block (702); in the fourth step, pull the adjusting rod (8) outward so that the locking block (801) enters the limiting slot (201); move the adjusting rod (8) to drive the support sleeve (2) to rotate, and the adjusting rod (8) moves to the location of the closed slot (101). The second isolation block (702) closes. Then press the adjusting rod (8), and after the locking block (801) enters the closed slot (101), rotate the adjusting rod (8) so that the stop bar (802) no longer blocks the movement of the sonar (9). Remove the sonar (9). The installation steps of the sonar (9) are as follows: First, initially install the sonar (9) on the support sleeve (2), and then pull the adjusting rod (8) located in the closed slot (101) outward to make the locking block (801) enter the limiting slot (201); Second, move the adjusting rod (8) to drive the support sleeve (2) to rotate, and the adjusting rod (8) moves to the location of the opening slot (102), the second isolation block (702) opens, and then press the adjusting rod (8) to enter the opening slot (102), and rotate the adjusting rod (8) to make the stop bar (802) move to the location of the sonar (9). The third step is to install the sonar (9) to the bottom. At this time, the sonar (9) will pass through the second isolation block (702) and approach the first isolation block (604) which is kept closed. Start the lifting cylinder (3), the support sleeve (2) descends and disengages from the contact sensor (5), the drive cylinder (605) starts and drives the rotating disk (602) to rotate, the first isolation block (604) opens, and at the same time the support sleeve (2) moves downward, so that the sonar (9) moves downward and enters the water through the first isolation block (604). The fourth step is to fix the sealing cover (10) on the opening of the installation cylinder (1).
