Description

Technical Field

[0001] The utility model relates to the technical field of submarine line pipe road measurement, in particular to a submarine line pipe road measurement sonar. Background Art

[0002] Submarine pipelines are an important part of marine engineering transportation and storage. Their safe and stable operation is directly related to the development efficiency of marine resources and environmental protection. However, submarine pipelines are affected by natural factors such as seawater scouring and seabed erosion all year round. Pipelines may be exposed and suspended, which not only increases the difficulty of pipeline maintenance, but also may cause serious production safety accidents. Therefore, it is particularly important to accurately measure and monitor submarine pipelines. Sonar technology, as an electronic device that uses the propagation characteristics of sound waves in water for underwater detection and positioning, has been widely used in submarine pipeline measurement due to its high precision, high resolution and real-time imaging. Sonar technology transmits sound waves and receives their reflected echoes, calculates the position and distance of underwater objects according to the propagation time and speed of the sound waves, and then realizes accurate measurement of the seabed topography, landforms and pipeline status. The existing submarine pipeline road measurement sonar can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] The existing sonar tail fins are usually tightly fixed to the sonar shell by parts such as bolts or clips. Therefore, during the disassembly process, these connections need to be carefully untied one by one, so it is inconvenient to disassemble the tail fins. However, the sonar shell needs regular maintenance and servicing to ensure its long-term stable operation. Due to the inconvenience in disassembling the tail fins and the sonar shell, maintenance personnel often need to spend more time and energy to complete the disassembly and installation work when performing maintenance operations, which not only increases the maintenance cost, but may also affect the normal use of the sonar shell. For this reason, we propose a submarine line pipe road measurement sonar to solve the above problems. Utility Model Content

[0023] In other embodiments, the limiting component 3 includes a connecting seat 31 arranged on the left end surface of the sonar housing 1. A connecting block 32 slides in the connecting seat 31. A tail fin 2 is provided at the left end of the connecting block 32. Spring grooves 33 are symmetrically formed on the upper and lower end surfaces of the connecting block 32. Springs 34 are provided on the inner walls of the spring grooves 33. The other ends of the springs 34 are fixedly connected with positioning rods 35. Positioning grooves 36 are formed on the inner walls of the connecting seat 31 corresponding to the outer end surfaces of the positioning rods 35. Two groups of sliding grooves 37 are symmetrically formed on the inner walls of the spring grooves 33 and the positioning grooves 36. Sliders 38 slide in the sliding grooves 37. The sliders 38 are fixed on the outer walls of the positioning rods 35;

[0024] By inserting the connecting block 32 in the limiting component 3 into the connecting seat 31, and then pushing the positioning rod 35 to slide in the spring groove 33 through the restoring force of the spring 34 and penetrate the positioning groove 36, the tail fin 2 is installed on the sonar housing 1. Then, by sliding the positioning rod 35 from the positioning groove 36 into the spring groove 33 and sliding the connecting block 32 out of the connecting seat 31 through the tail fin 2, the purpose of quick disassembly and quick installation of the tail fin 2 can be achieved, which is convenient for the staff to perform daily maintenance on the sonar housing 1 and the tail fin 2, and reduces the disassembly and assembly difficulty of the tail fin 2, thus improving the work efficiency of the staff.

[0025] In other embodiments, the protection component 4 includes a first protective cover 41 closely arranged on the outer wall of the sonar housing 1. A second protective cover 42 is closely arranged on the other end surface of the sonar housing 1.

Furthermore, the service life of the sonar housing 1 is effectively improved and the use cost of the sonar housing 1 is reduced.

[0027] In other embodiments, anti-slip patterns are provided on the outer end surfaces of the positioning rods 35. The spring grooves 33 and the positioning grooves 36 are formed as through holes adapted to the shape of the positioning rods 35;

[0028] With this design, the frictional force between the outer wall of the positioning rod 35 and the hand of the staff can be increased, so that when the staff pushes the positioning rod 35 into the spring groove 33, it is not easy to slip, preventing the restoring force of the spring 34 from pushing the positioning rod 35 back to its original position, and at this time, the situation where the staff needs to repeatedly operate the positioning rod 35 is avoided.

[0033] In other embodiments, rubber pads are provided on the inner and outer walls of the first protective cover 41 and the second protective cover 42, and the inner walls of the first protective cover 41 and the second protective cover 42 are tightly attached to the outer wall of the sonar housing 1;

[0034] With this design, the hard contact between the first protective cover 41, the second protective cover 42 and the sonar housing 1 can be reduced, preventing the situation that when the first protective cover 41 and the second protective cover 42 are installed on the outer wall of the sonar housing 1, they will cause frictional damage to the outer wall of the sonar housing 1. At the same time, when the first protective cover 41 and the second protective cover 42 are impacted by hard objects, the rubber pads can buffer the impact of the hard objects, making it not easy for the first protective cover 41 and the second protective cover 42 to be damaged.

[0035] The present utility model provides an underwater pipeline measurement sonar, and the specific working principle is as follows:

[0036] In use, first press the positioning rod 35 into the spring groove 33, so that the positioning rod 35 synchronously drives the slider 38 to slide in the sliding groove 37, and the positioning rod 35 slides into the spring groove 33 through the positioning groove 36. At the same time, the positioning rod 35 continuously presses against the inner wall of the spring groove 33 to compress the spring 34, causing the spring 34 to deform. Then, pull the connecting block 32 out of the connecting seat 31 through the tail fin 2, and the purpose of disassembling the tail fin 2 can be achieved. When the maintenance of the sonar housing 1 is completed, similarly, slide the connecting block 32 into the connecting seat 31, align the positioning rod 35 with the positioning groove 36, and then use the restoring force of the spring 34 to push the positioning rod 35 to reset and slide in the spring groove 33, and make the positioning rod 35 penetrate through the positioning groove 36. Then, put the sonar housing 1 into the seabed for use, and make the sonar housing 1 measure the pipeline path.
