Description

Technical Field

[0001] The invention relates to the technical field of ship mechanical engineering, and in particular to a multi-beam transducer installation and maintenance system. Background Art

[0002] As an advanced underwater topography measurement device, the multi-beam measurement system has been widely used in large-area, high-precision and near-real-time underwater scanning, with full coverage and high-efficiency measurement capabilities.

[0003] The current installation methods of multi-beam transducers mainly include fixed, side-mounted and gondola-mounted. Although the installation method directly fixed on the bottom of the ship is convenient, it requires the ship to be docked or put on the raft for maintenance, which not only takes a long time but also incurs huge costs. The side-mounted installation method often uses a temporary mechanism to lower the measuring equipment on the side of the ship. Since the multi-beam transducer is not rigidly fixed, it affects the measurement accuracy. The gondola installation method on the bottom of the ship arranges a small platform or fairing on the bottom of the ship. Although it can better meet the measurement accuracy requirements, it requires divers to perform maintenance and replace the transducer underwater in the later stage.

[0004] Therefore, the above technology has the problem that the multi-beam transducer is not installed firmly and accurately enough and is difficult to maintain. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the existing multi-beam transducer is not installed firmly and accurately enough.

[0029] The following is combined with Figure 1-5 The present invention is described in further detail.

[0030] The present invention discloses a multi-beam transducer installation and maintenance system, referring to Figure 1 and Figure 2 , including a hull 8, a reserved slot 1 in the hull, a rotatable cylinder 3, a driving assembly and a transducer 7. The reserved slot 1 in the hull is arranged on the hull 8 and the opening is located at the bottom of the hull 8. The rotatable cylinder 3 is arranged in the reserved slot 1 in the hull. The driving assembly includes a driving shaft 5 and a rotating mechanism 6. The driving shaft 5 is fixed at the central axis of the rotatable cylinder 3. The rotating mechanism 6 is connected to the driving shaft 5 and fixed on the hull 8. The rotating mechanism 6 can drive the driving shaft 5 to rotate. The transducer 7 is arranged on the rotatable cylinder 3. The driving assembly can drive the rotatable cylinder 3 to rotate and make the transducer 7 extend out of the reserved slot 1 in the hull. A cable is connected to the transducer 7. The cable passes through the driving shaft 5 and the rotatable cylinder 3 and is connected to a power source.

[0031] In a further embodiment, the upper portion of the reserved slot 1 for the hull is rectangular, the lower portion is arc-shaped, and the top of the reserved slot 1 for the hull is higher than the waterline 10 of the hull, the rotatable cylinder 3 is coaxial with the arc of the lower portion of the reserved slot 1 for the hull and has the same radius, the two bottom surfaces of the rotatable cylinder 3 are opposite to the side surfaces of the reserved slot 1 for the hull, a cutting plane 9 is provided on the cylindrical surface of the rotatable cylinder 3, the cutting plane 9 is flush with the bottom of the hull 8, and a sealing device is provided on the side of the cutting plane 9 for sealing the reserved slot 1 for the hull during navigation, which can reduce navigation resistance, and the rotatable cylinder 3 is provided with a concave storage space 4, three concave storage spaces 4 are provided and are all arranged on the cylindrical surface of the rotatable cylinder 3, the concave storage space 4 and the cutting plane 9 are distributed at 90°, the transducer 7 is fixed in the concave storage space 4, wherein the length and width of the concave storage space 4 are not greater than the length and width of the cutting plane 9, and the depth is not less than the height of the transducer 7, the size of the concave storage space 4 can be adjusted according to actual use, the sizes of the three concave storage spaces 4 can be different, and other measuring equipment can be installed in the concave storage space 4.

[0032] In a further embodiment, a hatch cover 2 is provided on the top of the reserved slot 1 of the hull, and the hatch cover 2 corresponds to the transducer 7 located on the top of the rotatable cylinder 3, and both the hatch cover 2 and the reserved slot 1 of the hull are sealed and waterproof structures.

[0033] The working principle of the present invention is as follows: the driving shaft 5 can be driven to rotate by the rotating mechanism 6, and the rotatable cylinder 3 can be rotated at the same time, so that the transducer 7 extends out of the hull 8 to work. When the transducer 7 fails, the rotatable cylinder 3 is driven to rotate by the rotating mechanism 6, so that the faulty transducer 7 is rotated to above the waterline 10 of the hull, and the hatch cover 2 is opened to replace the damaged transducer 7;

[0034] Reference Figure 1 When sailing, the cutting plane 9 is flush with the bottom surface of the hull 8 and the reserved groove 1 of the hull is sealed. At this time, there is no other moon pool or protrusion at the bottom of the hull 8, which can reduce the sailing resistance;

[0035] When performing measurement operations, refer to Figure 3 and Figure 4 The rotatable cylinder 3 can be rotated 180 degrees to make the transducer 7 at the top extend out of the reserved slot 1 of the hull, and then the rotating mechanism 6 is fixed to perform the measurement operation. During the operation, the angle of the transducer 7 can be adjusted according to the measurement needs to make it tilted. Figure 5 The rotatable cylinder 3 can also be rotated 90 degrees so that the transducer 7 on the side extends out of the reserved slot 1 of the hull for measurement. When the rotatable cylinder 3 is rotated 90 degrees, if the operating transducer 7 is damaged, the rotatable cylinder 3 can be rotated half a circle to make the transducer 7 on the other side of the rotatable cylinder 3 operate so that the damaged transducer 7 is located above the waterline 10 of the hull. The damaged parts can be taken out after opening the hatch cover 2, which saves time and facilitates maintenance.

[0036] The present invention installs multiple groups of multi-beam transducers in the concave storage space of a rotatable cylinder. The rotatable cylinder is connected to a rotating mechanism and then to the main hull, and its rotation is controlled by a high-precision drive shaft. The overall structure is relatively simple and reliable, which can ensure that the multi-beam transducer is installed in an accurate posture state. When the system is in a measuring operation state, the multi-beam transducer is positioned protruding from the bottom of the ship, which can avoid the adverse effects of bubbles on the bottom of the ship when the ship is sailing, thereby ensuring accurate measurement. During non-measuring operations, the tangent plane of the rotatable cylinder is flush with the bottom of the ship, and the reserved groove of the hull is sealed. At this time, there is no moon pool or protrusion on the bottom of the ship to affect the sailing resistance.
