In particular, the overall length of the strut post 21 is set to match the depth into which the underwater acoustic detection module 10 is immersed, and does not form any hollows other than the cable conduit 25 for rigidity. The fixing bolt 29 is screwed to the module connector 11 so that the underwater acoustic detection module 10 and the strut unit 29 are screwed together with the module connector 11, (20) are integrated with each other. The first positioner 27-1 of the first, second and third positioners 27-1, 27-2 and 27-3 is configured such that the underwater acoustic detection module 10 is completely removed from the water table 100, And the second positioner 27-2 is an indicator for locating the underwater acoustic detection module 10 in the inside of the water table 100 The third positioner 27-3 is a display that allows the strut column 21 to ascertain the moving position of the strut column 21 so that there is no resistance by the underwater acoustic detection module 10 when the waterproof vessel 100 is moved. Is an indication that the maintenance position where the strut post (21) rises as high as possible so that the underwater acoustic detection module (10) can be positioned and maintained on the deck of the strut pillar (100).

3 shows the detailed structure of the strut drive unit 30 provided by using the linear skin film frame 110. As shown in Fig.

Specifically, the strut drive unit 30 includes a connection bracket 31 fixed to the linear screen frame 110, a pulley 33 coupled to the connection bracket 31 and positioned above the linear screen frame 110, Is wound around the electric winch 35 by using an electric winch 35 and a pulley 33 which are coupled to the connection bracket 31 at a position adjacent to the pulley 33 and located at the upper portion of the linear skin frame 110, And a hook wire 37.

Particularly, the pulley 33, the electric winch 35 and the hook wire 37 are formed of two pairs. For example, the pulley 33 includes left and right pulleys 33 And the electric winch 35 is constituted by left and right electric winches 35-1 and 35-2 located outside the left and right pulleys 33-1 and 33-2, And the hook wire 37 is wound around each of the left and right electric winches 35-1 and 35-2 by using each of the left and right pulleys 33-1 and 33-2, , And right hook wires 37-1 and 37-2.

In this embodiment, the electric winch 35 and the left and right electric winches 35-1, 35-2 act in the same way as a general electric winch.

4 shows the detailed structure of the strut reinforcing unit 40 installed using the water-based fixture 100. As shown in Fig.

Specifically, the strut reinforcing unit 40 includes an opening hole 41 and an opening hole 41, which are laterally opened in the keel plate 121 woven with the hull reinforcement plate 123 at the bottom of the cabin of the water column 100, A plurality of reinforcing plates 43-1, 43-2 and 45 padded around the opening 121 and a strut box 47 located in the keel 121 to cover the opening hole 41. [

In particular, the opening hole 41 is formed in a rectangular shape in which the full length of the underwater acoustic detection module 10 can be extended. The reinforcing plates 43-1, 43-2 and 45 are attached to the left and right sides of the keel 121 in which the opening hole 41 is drilled, The left and right rear reinforcing plates 43-1 and 43-2 and the keel 121 are padded from the left and right sides of the keel 121 to the bottom of the cabin, And a front reinforcing plate 45 which is made of a resin. Therefore, the left and right rear reinforcing plates 43-1 and 43-2 and the front reinforcing plate 45 have the same function as the ship reinforcing plate 123. [ The strut box 47 is attached to the keel 121 so as to cover the opening hole 41 and forms a slit 47-1 through which the strut column 21 of the strut unit 20 penetrates. The slits 47-1 are formed in a streamlined shape like the strut pillars 21.

5 to 7 illustrate an example in which the underwater acoustic wave detection module system 1 is installed and operated in the canopy 100. The left and right pulleys 33-1 and 33-2 are connected to the pulley 33 and the left and right electric winch 35-1 and 35-2 are connected to the electric winch 35 and the left and right hook wires 37- 1 and 37-2 are described as hook wires 37. [ Particularly, when the underwater acoustic detection module 10 is lowered from the water level 100 or raised to the water level 100, the left and right electric winches 35-1 and 35-2 are rotated in opposite directions to each other. However, The underwater acoustic detection module 10 descends and the reverse rotation of the electric winch 35 is described as the ascending and descending of the underwater acoustic detection module 10 in the forward rotation of the electric winch 35. [ The hook wire 37 may be connected using the arbitrary structure of the strut pillar 21 but is connected to the strut pillar 21 via the first positioner 27-1.

5 is an operating state of the underwater acoustic detection module system 1 in which case the underwater acoustic detection module 10 of the underwater acoustic detection module system 1 is located underwater as much as possible in the anvil 100. To this end, the strut drive unit 30 operates to lower the strut unit 20, and the underwater acoustic detection module 10 descends into the strut unit 20 and descends into the water.

When the electric winch 35 is operated in a state in which the hook wire 37 of the electric winch 35 and the first lifting boss 27-1 of the strut pillar 21 are engaged with each other, The strut pillar 21 descends downward through the slit 47-1 of the strut box 47 and the opening hole 41 of the keel 121 by the forward rotation of the hook wire 37, The underwater acoustic detection module 10 provided in the indoor unit 21 exits the waterproof casing 100 and descends to the water. When the electric winch 35 is stopped after confirming that the first positioner 27-1 has entered the opening hole 41 of the strut box 47, the underwater acoustic detection module 10 is moved Thereby becoming an operating state for detecting and detecting underwater sound.

In this case, the strut post 21 remains connected to the hook wire 37 via the first positioner 27-1.

Figure 6 is a moving state of the underwater acoustic detection module system 1 in which case the underwater acoustic detection module 10 of the underwater acoustic detection module system 1 is lifted up out of the water and placed in the interior of the canal 100 . To this end, the strut drive unit 30 operates to raise and lower the strut unit 20, and the underwater acoustic detection module 10 ascends and descends to the strut unit 20 and ascends out of the water and out of the water.

For example, when the electric winch 35 is reversely rotated to wind the hook wire 37, the winding of the hook wire 37 is performed by pulling up the strut pillar 21, thereby pulling the second positioner 27- 2 are lifted up through the opening hole 41 of the keel 121 and the slit 47-1 of the strut box 47 and the underwater acoustic detection module 10 provided on the strut pillar 21 I come up to the inside of the cabin of I (100). When the underwater acoustic detection module 10 is moved to the horizontal position 100 when the electric winch 35 is stopped after confirming that the second positioner 27-2 has come out of the opening hole 41 of the strut box 47, The underwater acoustic detection module 10 is taken out of the water and the assumed state 100 is moved.

In this case, the strut post 21 remains connected to the hook wire 37 via the first positioner 27-1.

FIG. 7 is a maintenance state of the underwater acoustic detection module system 1, in which case the underwater acoustic detection module 10 of the underwater acoustic detection module system 1 is located on the deck of the anvil 100. To this end, the strut drive unit 30 operates to move the strut unit 20 up and down. The underwater acoustic detection module 10 ascends and descends to the strut unit 20 and ascends to the deck from the living room 100.

For example, when the electric winch 35 continues to be reversely rotated to continue the winding of the hook wire 37, the continuous winding of the hook wire 37 pulls the strut pillar 21 further upward, The positioner 27-3 moves up past the opening hole 41 of the keel 121 and the slit 47-1 of the strut box 47. [ Subsequently, the underwater acoustic detection module 10 installed along with the strut pillar 21 enters the inside of the strut box 47 and raises the strut box 47 so that the strut box 47 is supported on the deck of the waterproof box 100 And the electric winch 35 is stopped after confirming the underwater acoustic detection module 10 in a state where the strut box 47 is mounted on the deck of the oncoming vessel 100.

Then, after the strut box 47 is lifted or lifted, maintenance and inspection of the underwater acoustic detection module 10 is performed on the deck.

As described above, the underwater acoustic detection module system according to the present embodiment is a system in which the underwater acoustic detection module 10 is handed down using the keel 120 of the canopy 100 as a lifting / lowering passage, An electric winch 35 which is coupled to the line shielding frame 110 erected on the deck of the water column 100 to raise and lower the strut column 21 and an underwater acoustic detection module 10 So that the underwater acoustic detection module 10 can be easily maintained and operated on a small ship.
