[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figures 1-9 As shown, this embodiment provides an adjustable underwater acoustic testing deployment device, including:

[0037] The support mechanism includes a base 1, which has a retractable movable component inside for easy fixing and moving; the support component is rotatably connected to the base 1.

[0038] The testing mechanism, which is used to complete underwater acoustic testing, includes a sealing cylinder 17 suspended on one side of the support assembly, and a transmitting transducer 19 is raised and lowered at the bottom of the sealing cylinder 17.

[0039] A positioning mechanism is provided at the top of the transmitting transducer 19, and determines the initial position of the transmitting transducer 19 by contacting the bottom end of the sealing cylinder 17.

[0040] The measuring mechanism includes guide wheels 20 symmetrically arranged at the bottom of the sealed cylinder 17, a first conductive rope 18 for suspending the transmitting transducer 19 is movably arranged between the two guide wheels 20, and a measuring component for measuring the moving distance of the first conductive rope 18 is arranged inside the guide wheels 20.

[0041] This invention discloses an adjustable underwater acoustic testing deployment device. A retractable movable component is housed within the base 1 of the support mechanism, allowing for easy movement and fixation on a boat or shore, facilitating position adjustment. The support component, mounted on the base 1, supports the testing mechanism and facilitates control of its underwater movement. A watertight sealing cylinder 17 houses various electrical components. A transmitting transducer 19 is suspended from the bottom of the sealing cylinder 17 by a conductive first conductive rope 18, used to transmit and receive sound waves at different water depths to complete the underwater acoustic test. A positioning mechanism is located at the top of the transmitting transducer 19, used to position the transducer 19 relative to the sealing cylinder 17, facilitating accurate positioning of the transducer 19 at different water depths. This initial positioning also indicates the initial location of the transducer 19, facilitating subsequent determination of its immersion depth and improving the efficiency of the underwater acoustic test. This invention has a simple structure and flexible operation, enabling rapid and accurate positioning of the water depth of the transmitting transducer 19. Positioning is simpler and more convenient, suitable for different testing needs, improving the efficiency and accuracy of underwater detection, and enhancing the accuracy of measurement data.

[0042] In a further optimized design, a guide bracket 21 is provided at the bottom of the sealing cylinder 17, and a guide shaft 22 is provided on the guide bracket 21. A guide wheel 20 is rotatably connected to the guide shaft 22, and a measuring component is provided between the guide shaft 22 and the guide wheel 20. The measuring component includes a measuring groove 23 formed on the side wall of the guide shaft 22, a movable head 24 slidably connected in the measuring groove 23, a return spring 25 provided between the movable head 24 and the measuring groove 23, and an electrical connection between the movable head 24 and the control module in the sealing cylinder 17. A fixed head 26 is provided on the inner wall of the guide wheel 20, corresponding to the movable head 24. The movable head 24 and the fixed head 26 are in intermittent contact, and the movement distance of the first conductive rope 18 is measured by contact counting. The first conductive rope 18 is clamped between two guide wheels 20 for stabilizing and positioning the first conductive rope 18. At the same time, when the first conductive rope 18 moves, the guide wheels 20 rotate due to friction. The reset spring 25 in the measuring groove 23 pushes the movable head 24 out of the measuring groove 23. When the movable head 24 corresponds to and contacts the fixed head 26, the circuit connector on the movable head 24 completes a count in the control module. Then, the moving distance of the first conductive rope 18 is calculated by the number of counts, and the water entry moving distance of the transmitting transducer 19 is accurately calculated.

[0043] The design is further optimized. The positioning mechanism includes a fixed cylinder 27 fixed to the top of the transmitting transducer 19. A movable rod 28 is telescopically installed inside the fixed cylinder 27. The top of the movable rod 28 extends out of the fixed cylinder 27 and makes positioning contact with the bottom of the sealing cylinder 17. A positioning switch 29, electrically connected to the transmitting transducer 19, is installed between the bottom of the inner cavity of the fixed cylinder 27 and the bottom of the movable rod 28. When the transmitting transducer 19 rises to the top, the contact pad 45 at the top of the movable rod 28 contacts and is subjected to force at the bottom of the sealing cylinder 17, controlling the on / off state of the positioning switch 29. When the positioning switch 29 is on, the control module determines that the transmitting transducer 19 has risen to the correct position, stops rising, and simultaneously controls the counting of the measuring components to return to zero, facilitating subsequent measurements.

[0044] Furthermore, the positioning switch 29 in this embodiment includes a movable block 31 fixed to the bottom end of the movable rod 28, a fixed block 30 is provided in the inner cavity of the fixed cylinder 27, a movable conductive head 33 is provided in the bottom end of the movable block 31, and a fixed conductive head 32 is provided in the top end of the fixed block 30. When the movable rod 28 is squeezed, the movable block 31 drives the movable conductive head 33 to press down, thereby connecting the circuit of the fixed conductive head 32 and outputting an electrical signal.

[0045] Furthermore, in this embodiment, a positioning spring is provided between the fixed block 30 and the movable block 31. When the movable rod 28 loses its force, the positioning spring drives the movable rod 28 to reset.

[0046] In a further optimized design, a fixed bracket 34 is installed inside the sealed cylinder 17, and a winch 35 is mounted on the fixed bracket 34. A first conductive rope 18 extends into the sealed cylinder 17 and is wound around the winch 35. The winch 35 is electrically connected to the control module inside the sealed cylinder 17. The top end of the first conductive rope 18 extends into the sealed cylinder 17 and is wound around the winch 35. When the winch 35 is activated, the first conductive rope 18 is wound up and down on the winch 35, thereby controlling the raising and lowering of the transmitting transducer 19.

[0047] Further optimizing the design, the winch 35 includes a winch roller 36, with support shafts 37 fixed to both ends of the winch roller 36. Curved guide grooves 38 are provided on the support shafts 37, and these guide grooves 38 slide against guide blocks 39 mounted on a fixed bracket 34, causing the winch roller 36 to move horizontally during rotation. Several curved guide grooves 38 are provided on the support shafts 37 on both sides of the winch roller 36. The guide blocks 39 on the fixed bracket 34 extend into the guide grooves 38. When the winch roller 36 rotates, the curved guide grooves 38 allow the winch roller 36 to move horizontally on the fixed bracket 34, thereby ensuring that the first conductive rope 18 is evenly wound around the winch roller 36, improving the stability of the sealing cylinder 17.

[0048] Furthermore, in this embodiment, the support shaft 37 is connected to the driver, which is a motor or other device that can output power, and the device is controlled by the control module.

[0049] In a further optimized design, the support assembly includes a support rod 2 rotatably connected to the base 1. A support frame 3 is fixedly connected to the top of the support rod 2. The support frame 3 is eccentrically positioned, with its two ends located on either side of the support rod 2. Sealing cylinders 17 are movably suspended on one side of the support frame 3. In this embodiment, the support assembly includes a support rod 2 rotatably connected to the base 1, with a support frame 3 mounted on the support rod 2. The support frame 3 is eccentrically positioned, and the top of the support rod 2 is fixed to both ends of the support frame 3 by a pull rope 42, thereby improving strength.

[0050] Furthermore, a locking disc 43 is provided at the bottom of the support rod 2, and a locking bolt 44 is provided on the locking disc 43 to lock the support rod 2 and the base 1 to prevent them from rotating.

[0051] To further optimize the design, a counterweight assembly is movably suspended on the support frame 3. The weight of the counterweight assembly is adjustable to balance the torque of the support frame 3. The counterweight assembly includes an adjustable counterweight block 4, which is pulled onto the support frame 3 by a counterweight rope 5. Its suspension position on the support frame 3 is also adjustable, thereby adjusting its torque to balance the support frame 3 at different positions of the testing mechanism.

[0052] Further optimizing the design, the moving component includes several telescopic blocks 7 telescopically mounted at the bottom of the base 1, with movable wheels 8 at the bottom of each telescopic block 7. Adjusting rods 9 are connected to the top of each telescopic block 7 via a transmission mechanism, and the adjusting rods 9 are synchronously driven. Several telescopic grooves 6 are formed at the bottom of the base 1, within which the telescopic blocks 7 slide. The depth of the telescopic grooves 6 allows adjustment of the movable wheels 8 at the bottom of the telescopic blocks 7. When not in use, the movable wheels 8 retract into the telescopic grooves 6, and the bottom of the base 1 contacts the ground for easy fixation. When movement is required, the adjusting rods 9 rotate, changing their depth within the base 1 and extending the movable wheels 8 from the bottom of the telescopic blocks 7 out of the telescopic grooves 6 for easy movement. The synchronous transmission of the adjusting rods 9 allows rotation of any one adjusting rod 9 to drive the rotation of other transmission rods, thereby achieving stable lifting and lowering of the base 1.

[0053] Furthermore, in this embodiment, an adjusting sleeve 11 is slidably sleeved on the adjusting rod 9, and a transmission wheel 10 is fixedly connected to the outside of the adjusting sleeve 11. The transmission wheel 10 rotates synchronously with the adjusting rod 9, and the transmission wheels 10 are transmitted to each other through a transmission belt 15, which can drive all the adjusting rods 9.

[0054] Furthermore, a pressure wheel 41 is provided inside the base 1, and a transmission belt 15 is disposed between the pressure wheel 41 and the transmission wheel 10 to ensure stable transmission.

[0055] Furthermore, in this embodiment, a portion of the outer part of the adjusting rod 9 is prismatic, and the adjusting sleeve 11 is fitted onto the prismatic section of the adjusting rod 9, so that the adjusting rod 9 can slide longitudinally when it can drive the adjusting sleeve 11 to rotate.

[0056] Furthermore, the adjusting rod 9 is fitted with a fixing ring 12, which is separate from the adjusting rod 9 and does not contact it. The top of the fixing ring 12 is supported by several lifting springs 14, and a lifting ring 13 is provided. The top of the lifting ring 13 is in contact with the bottom of the adjusting sleeve 11 through several sliding wheels 40. When the adjusting rod 9 rotates, the adjusting sleeve 11 will descend accordingly. Subsequently, the compressed lifting springs 14 drive the adjusting sleeve 11 to reset through the lifting ring 13, so that the transmission is stable when controlling the lifting block to rise and fall in the lifting groove.

[0057] Furthermore, in order to prevent the telescopic block 7 from rotating with the adjusting rod 9, the telescopic block 7 in this embodiment is configured as a prism shape.
