Description

Technical Field

[0001] The utility model relates to the technical field of sonar detection equipment, in particular to a shallow layer profiler detection equipment based on synthetic aperture sonar technology. Background Art

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

[0003] Because it has the advantage that the lateral resolution is independent of the operating frequency and distance, it is often used in conjunction with a shallow layer profiler. In the prior art, since the transducer of the shallow layer profiler needs to emit and receive sound waves in the water, it is mostly dropped into the water by a wire rope when in use, and dragged back with the wire rope when recovered. When the wire rope is recovered, since there is no component to intervene in it, the wire rope is prone to entanglement and knotting when winding, and in severe cases, the wire rope may break, causing the detection equipment to be unable to be recovered normally. Therefore, it is necessary to design a shallow layer profiler detection equipment based on synthetic aperture sonar technology to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a shallow layer profiler detection device based on synthetic aperture sonar technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the transmission mechanism comprises a pulley fixedly mounted on the rotating shaft of the winding roller and the outer wall of the reciprocating screw, and the two pulleys are connected for transmission via a belt.

[0012] Beneficial effects of the utility model:

[0013] 1.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A shallow layer profiler detection equipment based on synthetic aperture sonar technology includes a detection equipment body 1 and a fixed plate 2. A vibration damping pad 3 is fixedly installed on the bottom wall of the fixed plate 2. The vibration damping pad 3 is made of rubber. The rubber vibration damping pad 3 has the characteristics of high elasticity and high viscosity, which can effectively buffer the force generated by vibration. A plurality of fixing holes are opened on the bottom walls of the fixed plate 2 and the vibration damping pad 3. Two support plates 4 are fixedly installed on the upper end surface of the fixed plate 2. A winding roller 5 and a reciprocating screw 6 are rotatably installed between the two support plates 4. The winding roller 5 and the outer wall of the reciprocating screw 6 are connected by a transmission mechanism. The transmission mechanism includes a pulley 7 fixedly installed on the rotating shaft of the winding roller 5 and the outer wall of the reciprocating screw 6. The two pulleys 7 are connected and driven by belts.

[0022] A motor 8 connected to a winding roller 5 is fixedly mounted on the outer wall of one of the support plates 4, a steel wire rope 9 is wound around the outer wall of the winding roller 5, the end of the steel wire rope 9 is fixedly connected to the upper end face of the detection device body 1, a screw sleeve 11 is threadedly mounted on the outer wall of the reciprocating screw 6, a limit rod 10 is fixedly mounted between the two support plates 4, the limit rod 10 slides through the screw sleeve 11, the limit rod 10 can limit the screw sleeve 11, so that the screw sleeve 11 can only move axially along the outer wall of the reciprocating screw 6, the outer wall of the screw sleeve 11 is connected to a connecting block 13 through a telescopic mechanism, the telescopic mechanism includes an electric push rod 12 fixedly mounted on the outer wall of the screw sleeve 11, the telescopic end of the electric push rod 12 is connected to the connecting block 1 The outer wall of the connecting block 13 is fixedly connected, and a guide wheel 15 is rotatably installed on the outer wall of the connecting block 13 through a connecting mechanism. The connecting mechanism includes a connecting frame 14 fixedly installed on the outer wall of the connecting block 13, and the guide wheel 15 is rotatably installed inside the connecting frame 14. The wire rope 9 can drive the guide wheel 15 to rotate inside the connecting frame 14 while winding, thereby reducing the wear of the wire rope 9 and the outer wall of the guide wheel 15. A cleaning sleeve 17 is fixedly installed on the upper end surface of the connecting block 13 through a connecting mechanism. The connecting mechanism includes a connecting rod 16 fixedly installed on the upper end surface of the connecting block 13, and the end of the connecting rod 16 is fixedly connected to the outer wall of the cleaning sleeve 17.

[0023] When the utility model is used, the fixing plate 2 can be fixedly installed on the deck through the cooperation of the multiple fixing holes and the fixing bolts. When tightening the fixing bolts, the vibration-damping pad 3 can be squeezed. The cooperation of the vibration-damping pad 3 can prevent the fixing bolts from loosening, thereby ensuring the firmness of the installation of the fixing plate 2. When the detection device body 1 is lifted out of the water, the motor 8 drives the winding roller 5 to rotate. The steel wire rope 9 can be wound around its outer wall through the rotation of the winding roller 5, thereby the detection device body 1 can be slowly lifted out of the water. While the detection device body 1 is being recovered, the electric push rod 12 can drive the connecting block 13 to extend outward, thereby the detection device body 1 can be pulled by the steel wire rope 9 to keep a certain safe distance from the hull, thereby preventing the detection device body 1 from colliding with the hull and being damaged.

[0024] At the same time, the winding roller 5 can drive the reciprocating screw 6 to rotate through two pulleys 7 connected by belts. The reciprocating screw 6 can drive the screw sleeve 11 to move back and forth on its outer wall by cooperating with the limit rod 10, so that the screw sleeve 11 can drive the guide wheel 15 to move back and forth between the two support plates 4. Driven by the reciprocating guide wheel 15, the wire rope 9 can be evenly wound on the outer wall of the winding roller 5, thereby avoiding the wire rope 9 from being entangled and knotted during the winding process, thereby avoiding the wire rope 9 from breaking and causing the detection equipment body 1 to be unable to be recovered normally. While the wire rope 9 is being wound, the cleaning brush 18 inside the cleaning sleeve 17 can clean the debris adhered to the outer wall of the wire rope 9, thereby avoiding the debris from damaging the wire rope 9, thereby increasing the service life of the wire rope 9.
