[0034] The embodiments of the present invention provide an acoustic cofferdam device and an ice area ship. By inventing the structure of the cofferdam that meets the diversified acoustic detection requirements for ice area navigation, the technical problem of the structure of the acoustic cofferdam for visual underwater detection of ice area ships is solved.

[0035] The embodiments of the present invention provide an acoustic cofferdam device, as Figures 1 to 3 shown. The acoustic cofferdam device includes:

[0036] The cofferdam 10 is watertightly connected to the hull bottom plate 30 corresponding to the center line (CL, Central Line) of the hull.

[0037] One or more sea connection openings 11 are provided in the hull bottom plate 30 at the bottom of the cofferdam 10, and a sea connection short pipe 12 and a support structure 13 are correspondingly provided for each sea connection opening 11.

[0038] A sea connection valve 14 is provided at the top of the sea connection short pipe 12, a maintenance box 15 is provided at the top of the sea connection valve 14, a lifting mechanism 16 is provided at the top of the maintenance box 15, and the lifting mechanism 16 is fixed to the wall plate of the cofferdam 10 through a support structure 17. Here, the lifting mechanism 16 can be welded to the wall plate structure of the cofferdam 10 through the support structure 17. The bottom end of the lifting mechanism 16 can be connected to the maintenance box 15 by a flange.

[0039] The lifting mechanism 16 includes a lifting rod 18. The end of the lifting rod 18 can carry an acoustic device to extend out of the hull bottom plate 30 into the seawater for acoustic detection after passing through the maintenance box 15, the sea connection valve 14, and the sea connection short pipe 12. Here, the structure of the sea connection valve 14 is a middle hole for the acoustic device to extend into the seawater through the hollow position. The acoustic device can transmit signals through the lifting mechanism 16. Here, the signal transmission method can be, for example, wired transmission or wireless transmission. The transmission cable for wired transmission can be laid through the lifting rod 18 of the lifting mechanism 16, for example.

[0040] In some embodiments, the aperture diameter of one or more sea connection openings 11 is DN250 - DN1000. Here, the number of sea connection openings 11 is not specifically limited. For example, Figures 1 to 3 in the design scheme of a scientific research ship for a certain base in an embodiment, 5 sea connection openings 11 are provided. Providing multiple sea connection openings 11 facilitates the use of multiple acoustic devices. For sea connection openings 11 with different aperture diameters, Figures 4 to 7 examples of sea connection short pipes 12 and support structures 13 with different calibers are respectively given for reference. It can be understood that the "short" of the sea connection short pipe 12 is relative to the lifting mechanism 16. A relatively shorter pipe diameter can provide relatively better stability. In actual application, the dimensions of the sea connection short pipe 12 are matched with the corresponding lifting mechanism 16 and the sea connection valve 14. The support mechanism 13 can be, for example, gussets arranged around the outer wall of the sea connection short pipe 12. Exemplarily, four gussets can be arranged in an average surrounding manner. In actual application, the specific strength, thickness, and the number of gussets of the support structure 13 can be adjusted according to actual needs.

[0041] In some embodiments, the number of lifting mechanisms 16 is the same as the number of sea connection openings 11.

[0042] In some embodiments, a strengthening structure 19 is provided on the wall plate of the cofferdam 10 to ensure the strength of the entire cofferdam 10.

[0043] In some embodiments, a heater 20 is provided in the cofferdam 10. The heater 20 can perform heating so that the entire structure of the cofferdam 10 can maintain a positive temperature during navigation in ice areas.

[0044] In some embodiments, the sea connection valve 14 and the sea connection short pipe 12 are watertightly connected by a flange 21, and the sea connection valve 14 and the maintenance box 15 are watertightly connected by a flange 21.

[0045] In some embodiments, the sea connection valve 14 and the sea connection short pipe 12 are watertightly connected by a flange, and the sea connection valve 14 and the maintenance box 15 are watertightly connected by a flange 21, including:

[0046] The flange 21 provided at the bottom end of the sea connection valve 14 is connected to the flange 21 provided at the top end of the sea connection short pipe 12.

[0047] The flange 21 provided at the top end of the sea connection valve 14 is connected to the flange 21 provided at the bottom end of the maintenance box 15.

[0048] A sealing gasket is provided between the butted flanges 21.

[0049] In some embodiments, the acoustic equipment includes at least one of the following: sonar equipment, underwater acoustic positioning equipment, and underwater acoustic communication equipment.

[0050] In some embodiments, the maintenance box 15 is provided with a glass observation hole 22, which can be used to observe the internal state of the sea connection valve 14. Here, the glass observation hole 22 is obtained by inlaying the glass for the observation hole opened on the side of the maintenance box 15. Through the glass observation hole 22, the state in the valve clearance passage during ice area navigation can be observed at any time.

[0051] In some embodiments, the maintenance box 15 is provided with a watertight and openable maintenance door 23, which can be used to take, place, and maintain the acoustic equipment through the maintenance door 23.

[0052] In some embodiments, the connection between each component of the acoustic cofferdam device of the present application is carried out by using a sealing gasket and a flange. The entire acoustic cofferdam device forms a watertight structure.

[0053] In some embodiments, in order to facilitate access to the cofferdam 10, a watertight door 24 is opened on the structure of the cofferdam 10, and it can be directly entered from a nearby room of the ship.

[0054] In some embodiments, a maintenance structure platform is built in the cofferdam 10 for maintaining the operation of the lifting rod 18. As Figure 2 shown, the maintenance structure platform includes a maintenance platform structure 25 provided corresponding to the top of the lifting mechanism 16 and a maintenance platform structure ladder 26 provided on the wall plate of the cofferdam 10, so that maintenance personnel can go up and down the maintenance platform structure 25 through the maintenance platform structure ladder 26 to maintain the operation of the lifting mechanism 16.
