Description

Technical Field

[0001] This utility model belongs to the field of multi-beam transducer technology, and in particular relates to a small multi-beam transducer structure. Background Technology

[0002] When testing multibeam transducers underwater, they are installed on the side of a ship or in the middle of an unmanned surface vessel. The traditional installation method is flange-mounted suspension, with multibeam transducers perpendicular to the flange for data acquisition. However, the data acquisition angle range of multibeam transducers is only 130°-140°. When encountering steep walls or shallow waters, the acquisition angle is blocked, making it impossible to collect accurate data and thus failing to display the complete steep wall terrain.

[0003] CN222047319U discloses a multi-beam transducer mounting bracket, comprising: a base; a rotating shaft rotatably mounted on the base; a rotating bracket mounted on the rotating shaft, used for mounting the multi-beam transducer, the rotating bracket rotating around the rotating shaft to allow the multi-beam transducer to rotate relative to the base; and a locking member penetrating the base and connecting to the rotating bracket, locking the relative position of the rotating bracket and the base when the rotating bracket stops rotating relative to the base. By mounting the multi-beam transducer on the rotating bracket, and rotating the bracket around the rotating shaft, the angle between the multi-beam transducer and the base can be adjusted, allowing the multi-beam transducer to collect complete underwater and steep-wall terrain information without blind spots. The locking member locks the adjusted rotating bracket, ensuring the stability of the multi-beam transducer's adjustment angle.

[0004] During use, it was found that the multi-beam transducer had to be removed from the water and manually adjusted each time the acquisition angle needed to be adjusted, before being placed back into the water and fixed in place. This was quite cumbersome. Therefore, a small multi-beam transducer structure needs to be designed to solve the above problems. Utility Model Content

Detailed Implementation

[0022] In the following description, embodiments of the miniature multi-beam transducer structure of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-2 This invention illustrates a compact multi-beam transducer structure according to an embodiment of the present invention, comprising:

[0024] Mounting cylinder 1 and rotating cylinder 2 are connected. Rotating cylinder 2 is rotatably connected to the bottom of mounting cylinder 1. Specifically, an external gear ring 12 is fixedly mounted on the surface of rotating cylinder 2, and a rotating rod 13 is rotatably connected to the surface of mounting cylinder 1. A gear 14 is fixedly mounted on the bottom of rotating rod 13, and gear 14 meshes with the external gear ring 12. Through the cooperation of external gear ring 12, rotating rod 13, and gear 14, the user can rotate the top of rotating rod 13 to drive the multi-beam transducer probe 7 to rotate in the horizontal direction, adjusting the horizontal acquisition angle of the multi-beam transducer probe 7. Specifically, a rotating ring 16 is welded to the bottom of mounting cylinder 1. The rotating ring 16 rotates in the inner cavity of rotating cylinder 2. Multiple balls 17 extending to the outer surface are installed in the inner cavity of rotating ring 16. The balls 17 are arranged in a ring on the surface of rotating ring 16. The inner cavity of rotating cylinder 2 is provided with anti-detachment grooves 18 that cooperate with the balls 17.

[0025] The system also includes a U-shaped mounting bracket 3 and a multi-beam transducer probe 7. A fixing cylinder 4 is welded to the top of the U-shaped mounting bracket 3, and the fixing cylinder 4 is fixedly installed at the bottom of the rotating cylinder rod 2. The multi-beam transducer probe 7 is rotatably connected to the bottom of the U-shaped mounting bracket 3 via a rotating shaft 5. Specifically, a bevel gear 9 is fixedly installed on the surface of the rotating shaft 5, and a rotating rod 10 is rotatably connected to the inner cavity of the fixing cylinder 4. The bottom of the rotating rod 10 extends into the inner cavity of the U-shaped mounting bracket 3 and is fixedly installed with a bevel gear 11. The bevel gear 11 meshes with the rotating rod 10, and the top of the rotating rod 10 passes through the inner cavities of the rotating cylinder rod 2 and the mounting cylinder rod 1 in sequence and extends to the outer side of the inner cavity of the mounting cylinder rod 1. Through the coordinated use of rotating rod 10, bevel gear 11 and bevel gear 9, the user can rotate the top of rotating rod 10 to drive the multibeam transducer probe 7 to rotate along the rotating shaft 5, adjusting the vertical acquisition angle of the multibeam transducer probe 7 without disassembling the mounting cylinder 1, which is convenient for the user to adjust the angle. Specifically, the fixed cylinder 4 and the rotating cylinder 2 are fixedly installed by a flange, the rotating shaft 5 is rotatably connected to the inner cavity of the U-shaped mounting bracket 3, two fixing plates 8 are welded to the surface of the rotating shaft 5, and mounting plates 6 are welded to the bottom of the two fixing plates 8. The mounting plates 6 and the multibeam transducer probe 7 are also fixedly installed by a flange.

[0026] Specifically, the inner cavity of the fixed cylinder 4 is fixedly installed with a conduit 15 for use with the multibeam transducer probe 7. The top of the conduit 15 passes through the inner cavities of the rotating cylinder 2 and the mounting cylinder 1 in sequence and extends to the outside of the inner cavity of the mounting cylinder 1. Through the setting of the conduit 15, the connecting wire of the multibeam transducer probe 7 can be passed through the inner cavity of the conduit 15 and connected to the receiving display on the ship. The connecting wire is guided, limited and protected to prevent the connecting wire from getting tangled.

[0027] Working Principle: In use, the user secures the multi-beam transducer probe 7 to the bottom of the mounting plate 6 using bolts. Then, the multi-beam transducer probe 7 is submerged in water, and the mounting rod 1 is fixed to the outside of the hull, thus installing the multi-beam transducer probe 7. When adjusting the vertical acquisition angle of the multi-beam transducer probe 7, rotating the rotating rod 10 drives the bevel gear 11 to rotate within the U-shaped mounting bracket 3, thereby rotating the bevel gear 9 and the rotating shaft 5. This, in turn, causes the multi-beam transducer probe 7 to rotate along the rotating shaft 5, adjusting the vertical acquisition angle of the multi-beam transducer probe 7. Similarly, when adjusting the horizontal acquisition angle of the multi-beam transducer probe 7... When collecting angle, rotating the rotating rod 13 drives the gear 14 to rotate, thereby causing the external gear ring 12 and the rotating cylinder rod 2 to rotate at the bottom of the mounting cylinder rod 1. At this time, the ball 17 will roll in the inner cavity of the anti-detachment groove 18, which in turn drives the multi-beam transducer probe 7 to rotate, adjusting the horizontal collection angle of the multi-beam transducer probe 7. It should be noted that, in order to prevent the angle of the multi-beam transducer probe 7 from changing during use, a rotation locking device can be set on the surface of the mounting cylinder rod 1 to limit and lock the rotation of the rotating rod 10 and the rotating rod 13. The rotation locking device can be, but is not limited to, a pin, a two-way ratchet, or other structure that can limit and lock its rotation.

[0028] In summary, this small multi-beam transducer structure allows for adjustment of the horizontal acquisition angle of the multi-beam transducer probe 7 by rotating the cylinder 2 and the mounting cylinder 1, and by adjusting the vertical acquisition angle of the multi-beam transducer probe 7 through the rotating shaft 5, thus achieving the purpose of multi-angle acquisition by the multi-beam transducer probe 7.
