However, when the ship is on trial voyage, the installed depth sounder sometimes breaks down and cannot be used, and the depth sounder needs to be overhauled or replaced. At this time, the ship has been launched, and if it is docked for replacement, it will take a lot of time and cost. Moreover, due to the tense docking period, it will also affect the construction process of the ships under construction in the dock.

Embodiment Construction
[0021] combine figure 1 , the method for underwater depth sounder replacement provided in this embodiment, combined with figure 1 Described as follows:
[0022] 1) The diver dives into the installation place of the underwater depth sounder, and installs a waterproof cover 11 on the bottom of the depth sounder installation box 3, and connects and fixes it with the waterproof cover connecting bolt 12;
[0023] 2) After the staff in the sounding cabin remove the connecting flange 4 of the waterproof cable 7 of the sounder, remove the old sealing device of the waterproof cable 7, that is, remove the original sealing tube 8, gasket 9 and rubber sleeve 10, such as figure 2 shown;
[0024] 3) The staff in the sounding cabin install a cylindrical sealing cylinder (13) at the end of the waterproof cable 7, such as image 3 shown;
[0025] 4), the diver removes the waterproof cover 11, replaces the depth sounder 6, and then reinstalls the waterproof cover 11, such as Figure 5 sh...

The invention provides a method for changing a depth finder under water. The method comprises the following steps that: 1) a diver dives to an underwater depth finder installing part, and installs a waterproof cover at the bottom of a depth finder installing box; 2) working personnel inside a depth finding cabin dismantle a connecting flange of a waterproof cable of the depth finder, and subsequently dismantle an old sealing device of the waterproof cable; 3) the working personnel inside the depth finding cabin install a cylindrical sealing barrel at the end part of the waterproof cable; 4) the diver dismantles the waterproof cover, changes the depth finder and subsequently reinstalls the waterproof cover; 5) the diver dismantles the cylindrical sealing barrel, and installs a new sealing device of the waterproof cable; and 6) after the working personnel inside the depth finding cabin install the connecting flange of the waterproof cable, the diver dismantles the waterproof cover and installs a fixing base plate at the bottom of the depth finder installing box, and thereby the whole change process is accomplished. In the dismantling process, ships do not need to enter the dock to be repaired, so that the time and cost are saved with simpleness and efficiency.
Description
technical field [0001] The invention belongs to the field of shipbuilding, and in particular relates to a method for replacing a depth sounder underwater. Background technique [0002] Modern ships are equipped with depth sounders, which can measure the depth of water at any time during the ship's navigation. This unit is mounted on the bottom shell and is installed at the dock stage. However, when the ship is on trial voyage, the installed depth sounder sometimes breaks down and cannot be used, and the depth sounder needs to be overhauled or replaced. At this time, the ship has been launched, and if it is docked for replacement, it will take a lot of time and cost. Moreover, due to the tense docking period, it will also affect the construction process of ships under construction in the dock. Contents of the invention [0003] The purpose of the present invention is to provide a method for overhauling or replacing the depth sounder during the sea trial of a ship, so as t...
