Abstract
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
The invention belongs to the shipbuilding field, be specifically related to a kind of method of changing echosounder under water.
Background technology
Modern ships all is equipped with echosounder, can record at any time the waters degree of depth in the ship's navigation process.This device is installed on the bottom plank, installs in the dock stage.But when boats and ships shake down, the already installed echosounder fault that happens occasionally can not be used, need to or change the echosounder maintenance, this moment, boats and ships descended water, change if lie up, time and the cost of cost are huge, and because of depressed place phase anxiety, also can have influence on the construction process of the inherent boatbuilding oceangoing ship in depressed place.
Summary of the invention
The method that the purpose of this invention is to provide the maintenance of echosounder in a kind of ship trial process or change avoiding the maintenance that lies up, thereby saves time and reduces cost.
For this reason, the method for changing echosounder under water provided by the invention comprises the steps:
1), the diver echosounder installation place of diving beneath the water, and in the bottom that echosounder is installed casing watertight cover is installed;
2), after the staff in the depth measurement cabin removes the butt flange of water-proof cable of echosounder, the old sealing arrangement of the water-proof cable of dismantling;
3), the staff in the depth measurement cabin installs the cylindrical seal cylinder in the water-proof cable end;
4), the diver removes watertight cover, changes echosounder, reinstalls afterwards watertight cover;
5), the diver pulls down the cylindrical seal cylinder, the novel sealing device of installation water-proof cable;
6), after the staff in the depth measurement cabin installs the butt flange of water-proof cable, the diver pulls down watertight cover, and after installing and fixing seat board in the bottom that echosounder is installed casing, whole Renewal process is finished.
The invention has the beneficial effects as follows: the process that originally changes cooperates underwater diver to finish by staff in the depth measurement cabin, and boats and ships do not need the maintenance that lies up, and have saved greatly spending, nor can affect the depressed place phase of other boats and ships.This method is feasible through putting into practice, and simple efficient.
Below in conjunction with the drawings and the specific embodiments the present invention is described in further detail.

Among the figure: 1-bottom plank; 2-seat board; 3-echosounder is installed casing; 4-butt flange; 5-bolt with flange; 6-echosounder; 7-water-proof cable; 8-sealed tube; 9-packing ring; 10-rubber coating; 11-watertight cover; 12-watertight cover tie bolt; 13-column type sealed chamber; 14-echosounder fixed base plate; 15-fixed base plate tie bolt.
The specific embodiment
In conjunction with Fig. 1, the method for changing echosounder under water that present embodiment provides is described below in conjunction with Fig. 1:
1), the diver echosounder installation place of diving beneath the water, and in the bottom that echosounder is installed casing 3 watertight cover 11 is installed, and is connected and fixed with watertight cover tie bolt 12;
2), after the staff in the depth measurement cabin removes the butt flange 4 of water-proof cable 7 of echosounder, the old sealing arrangement of the water-proof cable 7 of dismantling namely removes original sealed tube 8, packing ring 9 and rubber coating 10, as shown in Figure 2;
3), the staff in the depth measurement cabin is at water-proof cable 7 ends installation cylindrical seal cylinder (13), as shown in Figure 3;
4), the diver removes watertight cover 11, changes echosounder 6, reinstalls afterwards watertight cover 11, as shown in Figure 5;
5), the diver pulls down cylindrical seal cylinder 13, the novel sealing device of water-proof cable 7 is installed, as shown in Figure 6;
6), after the staff in the depth measurement cabin installs the butt flange 4 of water-proof cable 7, the diver pulls down watertight cover 11, and after installing and fixing seat board 14 in the bottom that echosounder is installed casing 3, whole Renewal process is finished.
As seen from Figure 1, echosounder is installed casing 3 and is installed on the bottom plank 1, and is fixed with seat board 2 between the two.
Above content is the further description of the present invention being done in conjunction with concrete preferred implementation, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
