[0002] Synthetic aperture sonar is a new type of two-dimensional imaging sonar. Its working principle is similar to that of synthetic aperture radar. It uses a sound array with uniform linear motion to form a large virtual (synthetic) aperture to improve the lateral resolution of the sonar.

[0003] Synthetic aperture sonar is widely used in civil fields such as seabed mapping, seabed geological survey, seabed engineering construction, detection of seabed obstacles and seabed sediments, and seabed mineral exploration. In the existing technology, when most synthetic aperture sonar devices are driven by underwater robots, due to the lack of protective measures, water plants and other debris will hang on the outer wall of the synthetic aperture sonar device, thereby affecting its detection effect, resulting in insufficient practicality of the synthetic aperture sonar device. Therefore, it is necessary to redesign a synthetic aperture sonar detection device for underwater burial exploration to address the above problems. Utility Model Content

The limiting plate 11 can limit the connecting frame 12. When the connecting frame 12 is connected to the fixed frame 2, the fixing pin 13 can be accurately inserted into the socket. The outer walls on both sides of the connecting frame 12 are slidably penetrated and installed with fixing pins 13. The outer walls on both sides of the fixed frame 2 are provided with sockets cooperating with the fixing pins 13. The ends of the two fixing pins 13 are fixedly installed with shifting blocks 14. The inner walls of the two shifting blocks 14 are connected to the outer wall of the connecting frame 12 through a fixing mechanism.

When it is hit, the protective frame 19 can transfer the force to the second support plate 18. The second support plate 18 is forced to squeeze the spring telescopic rod 17. The elasticity of the spring telescopic rod 17 can absorb and buffer the force, thereby preventing the sonar device 1 from being affected by the force during detection.

When there are too many debris adhering to the outer wall of the filter plate 20, the second motor 23 drives the reciprocating screw 22 to rotate, and the reciprocating screw 22 drives the screw sleeve 25 to move by cooperating with the stabilizing rod 24.
