Description
Technical Field
[0001] This utility model relates to the field of seabed exploration technology, and in particular to an AUV shallow-sea sonar imaging profiler. Background Technology
[0002] AUV (Aquamarine Underwater Vehicle) shallow-sea sonar imaging profilers are autonomous underwater vehicles used for acoustic imaging and analysis in shallow waters. Combining an AUV platform, sonar technology, and imaging algorithms, they generate high-resolution topographic images and perform in-depth analysis of the acquired data. These instruments are widely used in marine monitoring, resource exploration, and other fields, particularly in providing detailed topographic information in shallow water environments, thus improving the efficiency and accuracy of marine missions. AUV shallow-sea sonar imaging equipment may face various challenges in the underwater environment, such as obstacles like seaweed and gravel, but may also be subject to impacts or collisions with hard objects. Utility Model Content
[0003] To address the aforementioned problems, this invention proposes an AUV shallow subsurface sonar imaging profiler to more accurately resolve the problems described above.
[0004] This utility model is achieved through the following technical solution:
[0005] This invention proposes an AUV shallow-layer sonar imaging profiler, comprising a protective head body. One end of the protective head body is provided with an adapter seat, and an air-blowing core is rotatably connected inside the adapter seat. An exhaust port is provided on the outer wall of the protective head body, and a biomimetic fish gill grille is provided at the opening of the exhaust port. The outer wall of the rotating part of the air-blowing core is provided with a front fan blade, and the inlet of the air-blowing core is provided with a side fan blade. The adapter seat and the air-blowing core form an annular air guide channel, which corresponds to the position of the front fan blade. An annular air pipe is provided outside the adapter seat, and the annular air pipe is connected to the annular air guide channel inside the adapter seat through an air guide branch pipe. An air inlet is connected to the top of the annular air pipe.
[0006] Furthermore, the biomimetic gill grid is composed of several air guide plates arranged at equal intervals, with the air guide plates positioned obliquely to the rear side.
[0007] Furthermore, the guide vanes of the front fan blades are arranged at an angle, and the side fan blades are turbofan blades.
[0008] Furthermore, the annular trachea is connected to several air guide branches, and these several air guide branches are arranged in a ring array and connected to the annular air guide channel inside the adapter.
[0009] Furthermore, the end of the protective head body away from the adapter is integrally formed with an air barrier, which is a conical guide plate body recessed into the interior of the protective head body.
[0010] Furthermore, the outer port of the adapter is connected to a protective mesh cover, which is a rigid mesh cover with a conical cross-section.
[0011] The beneficial effects of this utility model are:
[0012] 1. In this utility model, the air inlet is connected to the air supply equipment on the hull through an air pipe, allowing gas to enter the interior of the protective head body and the gas to be discharged along the exhaust port. The biomimetic gill grid set at the exhaust port opening guides the gas to the rear side, and the ejected gas can quickly create a buffer space, effectively preventing the body from hitting hard objects during rapid movement.
[0013] 2. In the process of the equipment moving, when the water enters the protective head body, it acts on the side fan blades, thereby driving the air blower core to rotate. When the air blower core rotates, the gas introduced by the air guide pipe is stirred by the front fan blades to form bubbles, and the bubbles are evenly introduced into the protective head body, which plays the role of blowing air and uniform gas.

A ring-shaped air guide channel is formed at the junction of 01 and the air-blowing core 2. The ring-shaped air guide channel corresponds to the position of the front fan blade 201. A ring-shaped air pipe 102 is provided on the outside of the adapter 101. The ring-shaped air pipe 102 is connected to the ring-shaped air guide channel inside the adapter 101 through the air guide branch pipe 1021. An air inlet 1022 is connected to the top of the ring-shaped air pipe 102. There are several air guide branch pipes 1021 connected to the ring-shaped air pipe 102, and the several air guide branch pipes 1021 are arranged in a ring array and connected to the ring-shaped air guide channel inside the adapter 101. The air inlet 1022 is connected to the air supply equipment on the hull through the air pipe, so that the gas enters the interior of the protective head body 1, and the gas is discharged along the exhaust port 103. The biomimetic gill grid 1031 provided at the opening of the exhaust port 103 guides the gas to the rear, so that a layer of gas film is formed on the exterior of the AUV shallow-sea sonar imaging profiler.
[0022] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: In this utility model, the air inlet 1022 is connected to the air supply equipment on the hull through an air pipe, so that the gas enters the interior of the protective head body 1, and the gas is discharged along the exhaust port 103.

The guide plate of the front fan blade 201 is set at an angle, and the side fan blade 202 is a turbo fan blade.
