[0002] The combinable acoustic probe support pipe is a special pipe structure used to support and fix the acoustic probe so that measurements can be made in areas where sound monitoring or acoustic research is required. It consists of multiple combinable components and the length of the pipe can be flexibly adjusted according to actual needs. This structure is widely used in the fields of acoustic monitoring, acoustic imaging, and acoustic experiments.

[0003] A Chinese patent with publication number CN115849218A discloses a sonar lifting device, including a support platform and a lifting mechanism fixedly arranged on the support platform. The support platform is used to fix the lifting mechanism on the hull. The lifting mechanism is used to lift the sonar and drive the sonar to move horizontally to complete the sonar recovery or delivery. The overall structure of the device is simple and efficient, which can well avoid the sonar from being bumped during recovery, reduce the risk of sonar damage, and improve work efficiency.

[0004] When the sonar hoisting device of the above patent is used to set up the acoustic probe, the acoustic probe cannot be stably fixed by the connection of the cable. The position of the acoustic probe itself depends entirely on its own weight to offset the push of the water flow, and it is difficult to be stably located at the desired position.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that the sonar hoisting device in the prior art cannot stably fix the acoustic probe by relying on the connection of the cable when setting up the acoustic probe, and the position of the acoustic probe depends entirely on its own weight to offset the push of the water flow, and it is difficult to stably locate at the required position, this embodiment provides the following technical solutions:

[0022] A detachable moon pool for sensors used in offshore operations in glacial areas, comprising a bracket 1, such as Figure 1 and 5 As shown, when the acoustic probe is set up on the edge of the hull, the bracket 1 is placed on the hull in advance for convenience, a fixing frame 3 is provided on one side of the upper end of the bracket 1, and the fixing frame 3 is welded and fixed to the bracket 1, and the subsequent connection pipe 2 can be penetrated and connected through the protruding and welded fixing frame 3;

[0023] In this embodiment, the interior of the fixing frame 3 is provided with connecting pipes 2, and the number of connecting pipes 2 corresponds to the diving depth of the acoustic probe. Figure 2 , Figure 3 and Figure 4 As shown, a first installation cavity 12 is provided at the upper end of the connecting tube 2, and a second installation cavity 13 is provided at the lower end of the connecting tube 2. The second installation cavity 13 and the first installation cavity 12 are both provided with threaded walls that are threadedly matched with each other. Between two adjacent connecting tubes 2, the second installation cavity 13 is rotated and embedded in the first installation cavity 12 to complete the connection;

[0024] In this embodiment, if Figure 2 and Figure 5As shown, four pairs of support plates 8 are evenly distributed in an annular shape on the outside of the connecting tube 2, and a limiting plate 7 is arranged on one side of the outside of the four pairs of support plates 8, and the limiting plate 7 and the support plate 8 rotate with the transmission shaft 9 as the center of the circle, and a tray 5 is arranged on the upper end of the limiting plate 7, and the tray 5 is located around the first installation cavity 12, and the tray 5 and the connecting tube 2 are an integral structure, and the uppermost connecting tube 2 limits the limiting plate 7 through the tray 5, and the limiting plate 7 is attached to the upper end of the fixing frame 3 to complete the installation of multiple connecting tubes 2 of the entire connection, so that the connecting tube 2 and the acoustic probe at the lower end are fixed to the upper end of the bracket 1;

[0025] In this embodiment, the transmission shaft 9 is welded and fixed to the limiting plate 7, and a sodium storage cavity 10 is provided on both sides of the middle of a pair of support plates 8. Figure 2 and Figure 5 As shown, the transmission shaft 9 passes through and extends to the two ends of the sodium storage chamber 10. The interior of the sodium storage chamber 10 is surrounded by a spiral ring 11, and the two ends of the spiral ring 11 are respectively welded and fixed to the transmission shaft 9 and the connecting pipe 2. The limiting piece 7 can be actively rotated and turned toward the tray 5 through the resilience of the sodium storage chamber 10. After another connecting pipe 2 is rotated and installed at the top end of the structure connected by multiple connecting pipes 2, the limiting piece 7 that is now in contact with the fixed frame 3 is manually rotated and stored, so that the connecting pipe 2 corresponding to the limiting piece 7 can pass through the through hole inside the fixed frame 3, and the limiting piece 7 corresponding to the connecting pipe 2 that has just been installed and fixed can contact the fixed frame 3 and complete the suspension;

[0026] In this embodiment, a lower protective ring 4 is disposed outside the second installation cavity 13 of the lowermost connecting pipe 2. Figure 4 As shown, the inner wall of the lower protective ring 4 is threadedly matched with the second installation cavity 13 of the bracket 1. The lower protective ring 4 can be wrapped around the second installation cavity 13 by rotation, so as to prevent the second installation cavity 13 from diving with the acoustic probe and contacting the liquid for a long time, thereby improving the service life of the connecting pipe 2;

[0027] In this embodiment, a rubber pad 6 for buffering is provided between the tray 5 and the limiting sheet 7, and the rubber pad 6 is fixed to the tray 5 by bolts. Figure 2 As shown, the limiting sheet 7 is prevented from directly colliding with the tray 5 after being turned over, thereby avoiding damage caused by the collision and generating loud noise.

[0028] Working principle: when using the device and setting up the acoustic head, the bracket 1 drives the fixed frame 3 to be hung on the edge of the hull. After setting up and fixing the fixed frame 3, the acoustic probe is fixed to the lower end of the connecting pipe 2 in advance, and the connecting pipe 2 corresponding to the acoustic probe is passed through the fixed frame 3. The limiting plate 7 is supported by the tray 5 and fits the upper end of the fixed frame 3. According to the diving requirements of the acoustic probe, another connecting pipe 2 is rotatably installed on the upper end of the fixed frame 3. The connected connecting pipe 2 is rotatably installed to the first installation cavity 12 position of the connecting pipe 2 inside the fixed frame 3 through the second installation cavity 13. After one end is pulled upward longitudinally, the limiting plate 7 can be rotated, and the limiting plate 7 fitted with the fixed frame 3 can be rotated to extend into the fixed frame 3, and the limiting plate 7 corresponding to the connecting pipe 2 just installed The plate 7 fits the fixed frame 3, thereby completing the diving of the acoustic probe. When adjusting the acoustic probe longitudinally upward, the connecting tube 2 is stretched and moved upward with the help of the hydraulic device, and the limiting plate 7 corresponding to the uppermost connecting tube 2 moves away from the fixed frame 3. The limiting plate 7 of another connecting tube 2 at the lower end of the uppermost connecting tube 2 contacts the lower end of the fixed frame 3. As the hydraulic device continues to pull, it rotates toward the center position of the fixed frame 3. Continuous longitudinal upward pulling can make the rotating limiting plate 7 move to the upper end of the fixed frame 3, lose the restriction of the fixed frame 3, and thus make the limiting plate 7 reset and parallel to the upper end of the fixed frame 3. The pulled limiting plate 7 replaces the previous limiting plate 7 to contact the fixed frame 3 to complete the installation of the overall connecting tube 2, and then the connecting tube 2 exposed at the upper end of the fixed frame 3 can be rotated to disassemble.
