Description

Technical Field

[0001] The invention belongs to the field of marine engineering, and in particular relates to a universal platform for underwater detection acoustic array testing. Background Art

[0002] Underwater acoustic target detection technology is the core technology in marine application fields such as environmental perception, ocean monitoring, resource exploration, and intelligence collection. As an important application carrier of this technology, the research and development, debugging, and testing of underwater detection acoustic arrays are of great significance.

[0003] The pool test and debugging of underwater detection acoustic arrays are generally carried out by manually pulling a single transducer into the water or using a simple frame to carry several transducers into the water, but this method is not suitable for lake and sea tests.

[0004] Since the test conditions of the existing testing methods for underwater detection acoustic arrays are significantly different from the actual working conditions, on the one hand, the simple framework is not suitable for field test environments, and on the other hand, the test results cannot well reflect the performance of the detection acoustic array under actual working conditions. Summary of the invention

[0005] The present invention proposes a universal platform for underwater detection acoustic array testing, which can carry a transmitting transducer and a receiving transducer at the same time and adapt to different receiving transducer array arrangements.

[0006] The present invention is achieved through the following technical solutions.

[0007] A universal platform for underwater detection acoustic array testing, comprising: a transverse rotating shaft interface (1), a transmitting transducer (2), a receiving transducer array (3), a longitudinal rotating shaft interface (4), and a platform shell (5); wherein the transverse rotating shaft interface is fixed to a front end cover by screw connection, and the front end cover and the platform shell are fixed by screw connection; the transmitting transducer is fixed to a transmitting transducer hole seat of the platform shell by screws; the receiving transducer array is mounted on a receiving transducer mounting seat of the platform shell and is fixed by screw ring compression; and the longitudinal rotating shaft interface is welded and mounted in the radial direction of the platform shell.

[0008] The platform shell (5) is composed of a top ring (13), a cylindrical shell (14), a transmitting transducer hole seat (15), a water hole (16), a counterweight mounting frame II (17), a receiving transducer mounting seat (18), a counterweight mounting frame I (19), and a receiver mounting frame (20). The cylindrical shell (14) is formed by roll welding, and a top ring (13) is welded at each end. A water hole (16) is welded vertically in the middle of the shell, and a counterweight mounting frame II (17) is welded on the inner wall of the water hole (16). The receiving transducer mounting seats (18) are welded on both sides of the shell, and the counterweight mounting frame I (19) and the receiver mounting frame (20) are welded inside the shell.

[0009] Beneficial effects of the present invention:

[0010] 1. The transverse rotating shaft interface and the longitudinal rotating shaft interface of the present invention can be connected to an external rotating shaft to adjust the platform posture in real time underwater. The transverse rotating shaft interface can be disassembled when not in use;

[0011] 2. The platform shell of the present invention has four vertical water holes, which effectively reduces the excess positive buoyancy brought by the cylindrical shell and reduces the overall weight of the platform;

[0012] 3. A counterweight mounting frame is welded in the water hole of the present invention, and multiple counterweights II and III can be installed as needed. The counterweight can be conveniently adjusted while ensuring the air tightness of the platform, thereby achieving the purpose of adjusting the underwater buoyancy of the platform;

[0013] 4. The present invention has a simple structure and a reliable system, and can effectively simulate the application scenarios of underwater detection arrays, making the test operation easier and the test data more accurate. BRIEF DESCRIPTION OF THE DRAWINGS
