[0002] In the fields of modern marine engineering, ship technology and underwater detection, sonar systems play an extremely critical role. Sonar equipment is widely used in various underwater vehicles or marine facilities such as ships, submarines, and underwater working platforms. However, since sonar devices work 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, repaired and replaced.

[0003] Traditional sonar maintenance and replacement methods have many inconveniences and limitations. When a sonar needs to be repaired or replaced, it is often necessary to dock the underwater vehicle or marine facility at a special maintenance dock or shipyard, and send professional divers with tools to operate in the water, or dock the hull at a designated location, and then the operator drives the boat to replace it from the outside of the bottom of the ship. This method not only consumes a lot of time and manpower and material resources, but is also severely restricted by marine environmental conditions (such as wind and waves, water temperature, underwater visibility, etc.), resulting in low efficiency of maintenance and replacement work.

[0004] Therefore, there is an urgent need for an integrated device that can perform sonar maintenance and replacement in the cabin to overcome the shortcomings of the existing technology, improve the efficiency of sonar maintenance and replacement, and reduce maintenance costs and dependence on marine environmental conditions.

Conversely, the adjusting rod 8 is pulled upward, the block 801 moves with the adjusting rod 8 and enters the limiting slot 201, and the compression spring rebounds and drives the block 801 to move outward into the corresponding placement slot. At this time, the adjusting rod 8 can only slide up and down and cannot rotate around its own axis, and turning the adjusting rod 8 can drive the supporting sleeve 2 to rotate.

[0032] like Figure 12-13As shown, the second isolation assembly 7 includes a connecting slide frame 701, a second isolation block 702, a sealing sleeve 703 and a conical ring 704; there are four second isolation blocks 702, and each second isolation block 702 is covered with a sealing sleeve 703; each second isolation block 702 corresponds to a connecting slide frame 701, the connecting slide frame 701 is fixedly installed in the installation cylinder 1, and a linear slide is provided on the connecting slide frame 701, and the second isolation block 702 is slidably installed on the corresponding connecting slide frame 701 The conical ring 704 is wide at the top and narrow at the bottom, and the top surface is rotatably mounted on the mounting cylinder 1. Four curved limit slide grooves 7041 extending from the outside to the inside are provided on the inclined surface corresponding to the four second isolation blocks 702; a pin is fixedly installed on each second isolation block 702, and the pin is slidably installed in the corresponding limit slide groove 7041; a sliding rod is fixedly installed on the top of the conical ring 704, and a mounting hole is provided on the support sleeve 2 corresponding to the sliding rod, and the sliding rod is slidably installed in the corresponding mounting hole; Specifically, after each connecting slide frame 701 moves to the bottom end of the corresponding linear slide, the four second isolation blocks 702 can be assembled into a complete downward-protruding pyramidal isolation plate; due to the sliding connection between the support sleeve 2 and the conical ring 704, the conical ring 704 can rotate with the support sleeve 2, and the support sleeve 2 can move up and down relative to the conical ring 704; the support sleeve 2 can drive the conical ring 704 to rotate, and the rotation of the conical ring 704 will drive the second isolation block 702 to move. When the limit slot 201 is connected to the closing slot 101, the four second isolation blocks 702 are closed, and when the limit slot 201 is connected to the opening slot 102, the four second isolation blocks 702 are opened.

[0033] like Figure 9-11As shown, the first isolation component 6 includes a support frame 601, a rotating disk 602, a fixed disk 603, a first isolation block 604 and a drive cylinder 605; the support frame 601 is fixedly installed in the installation tube 1, the rotating disk 602 is rotatably installed in the support frame 601, and the fixed disk 603 is fixedly installed at the bottom of the support frame 601; the drive cylinder 605 adopts a servo electric cylinder, and is provided with two, which are centrally symmetrically arranged on both sides of the rotating disk 602; each drive cylinder 605 is rotatably installed on the support frame 601, and the telescopic end is rotatably connected to the edge of the rotating disk 602; the drive cylinder 605 is electrically connected to the contact sensor 5; a regular hexagonal limiting slide groove 6021 is provided on the bottom surface of the rotating disk 602, and a pair of Six limiting slide grooves 6031 are provided on the six sides of the limiting slide groove 1 6021; six first isolation blocks 604 are provided between the rotating disk 602 and the fixed disk 603; each first isolation block 604 is fixedly installed with a pin shaft, and the upper and lower ends of the pin shaft are respectively slidably installed in the limiting slide groove 1 6021 and the corresponding limiting slide groove 2 6031; each first isolation block 604 is triangular, one side of which is fixedly provided with a cutting knife 6041, and the other side is provided with a cutting knife groove 6042 corresponding to the cutting knife 6041; adjacent first isolation blocks 604 can slide relative to each other, and the cutting knife 6041 of one first isolation block 604 will be inserted into the cutting knife groove 6042 of another adjacent first isolation block 604; Specifically, the telescopic end of the drive cylinder 605 is telescopic to drive the rotating disk 602 to rotate, and drive the first isolation block 604 to move; when the first isolation blocks 604 all move outward, a gradually expanding opening will be formed in the middle position of the six first isolation blocks 604, conversely, when the first isolation blocks 604 all move inward, the opening will gradually shrink until it disappears; in the process of the first isolation block 604 moving, the cutting knife 6041 on the first isolation block 604 can cut the water plants and other debris wrapped around the first isolation block 604, thereby effectively cleaning the first isolation block 604; when the contact sensor 5 contacts the contact ring 202, the contact sensor 5 sends an electrical signal to the drive cylinder 605, and the drive cylinder 605 starts, causing the first isolation block 604 to gradually close, conversely, when the contact ring 202 is separated from the contact sensor 5, the drive cylinder 605 will start again, causing the first isolation block 604 to gradually open.

[0034] like Figure 3 As shown, corresponding marks are provided on the installation tube 1 at locations corresponding to the closed slot 101 and the open slot 102 .

[0035] A transparent plate is provided on the top surface of the closing cover 10 to facilitate observation of the specific conditions of each component in the installation tube 1.

[0036] The method of using this embodiment is as follows: 1. Disassembly of Sonar 9 The first step is to remove the closing cover 10; The second step is to start the lifting cylinder 3 to drive the support sleeve 2 to move upward, and the sonar 9 passes through the first isolation block 604 and enters the inner side of the first isolation block 604 until the contact ring 202 presses the contact sensor 5 driven by the lifting cylinder 3, and the support sleeve 2 stops moving. At the same time, the driving cylinder 605 is started, and the first isolation block 604 is closed; The third step is to rotate the sonar 9 to move upward in the support sleeve 2. When the sonar 9 moves upward to be blocked by the blocking rod 802 (but still maintains a distance at one end), the sonar 9 passes through the second isolation block 702 and enters the inner side of the second isolation block 702. The fourth step is to pull the adjusting rod 8 outwards to make the block 801 enter the limit slot 201; toggle the adjusting rod 8 to drive the supporting sleeve 2 to rotate, and the adjusting rod 8 moves to the location of the closed slot 101, and the second isolation block 702 is closed. Then, the adjusting rod 8 is pressed, and after the block 801 enters the closed slot 101, the adjusting rod 8 is rotated so that the blocking rod 802 no longer blocks the movement of the sonar 9, and finally the adjusting rod 8 is pressed to the bottom end of the closed slot 101; Step 5. Continue to rotate sonar 9, remove sonar 9, and then install new sonar 9.

[0037] 2. Install Sonar 9 The first step is to partially thread the sonar 9 onto the support sleeve 2 (the sonar 9 is not rotated to the bottom at this time), and then pull outward the adjustment rod 8 initially located in the closed slot 101, so that the block 801 enters the limit slot 201; The second step is to turn the adjusting rod 8 to drive the supporting sleeve 2 to rotate, and the adjusting rod 8 moves to the location of the open slot 102, and the second isolation block 702 opens. Then, the adjusting rod 8 is pressed, and the adjusting rod 8 enters the open slot 102, and the adjusting rod 8 is rotated to move one of the blocking rods 802 at the top of the adjusting rod 8 to the top of the sonar 9. The third step is to continue rotating the sonar 9 until it is rotated 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 remains closed. The lifting cylinder 3 is started to drive the contact ring 202 to descend, and the contact ring 202 is separated from the contact sensor 5. The driving cylinder 605 is started and drives the rotating disk 602 to rotate, and the first isolation block 604 is opened. At the same time, the supporting sleeve 2 moves downward under the drive of the lifting cylinder 3, so that the sonar 9 moves downward and enters the water through the first isolation block 604. The fourth step is to fix the closing cover 10 on the barrel opening of the mounting barrel 1.

[0038] 3. Sonar 9 Emergency Obstacle Avoidance When the sonar 9 detects an obstacle on the forward route or the hull needs to break ice to advance, the sonar 9 needs to be retracted into the hull. At this time, the lifting cylinder 3 is started to drive the support sleeve 2 to move upward, and the sonar 9 passes through the first isolation block 604 and enters the inner side of the first isolation block 604 until the contact ring 202 presses the contact sensor 5 driven by the lifting cylinder 3, the support sleeve 2 stops moving, and the drive cylinder 605 is started at the same time, and the first isolation block 604 is closed, thereby achieving emergency obstacle avoidance.

Then, the adjusting rod (8) is pressed, and after the block (801) enters the closed slot (101), the adjusting rod (8) is rotated so that the blocking rod (802) no longer blocks the movement of the sonar (9), and the sonar (9) is removed; The installation steps of Sonar (9) are as follows: The first step is to preliminarily install the sonar (9) on the supporting sleeve (2), and then pull the adjustment rod (8) located in the closed slot (101) outward to make the block (801) enter the limit slot (201); The second step is to turn the adjusting rod (8) to drive the supporting sleeve (2) to rotate, so that the adjusting rod (8) moves to the location of the opening slot (102), and the second isolation block (702) opens. Then, the adjusting rod (8) is pressed, so that the adjusting rod (8) enters the opening slot (102), and the adjusting rod (8) is rotated to move the blocking rod (802) to the position directly above 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) that remains 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 the support sleeve (2) moves downward, so that the sonar (9) moves downward and passes through the first isolation block (604) into the water; The fourth step is to fix the closing cover (10) on the tube mouth of the installation tube (1).
