Description

Technical Field

[0001] This utility model relates to the field of transducer technology, and in particular to a corrosion-resistant deep-sea transducer. Background Technology

[0002] Corrosion-resistant deep-sea transducers are core equipment in marine exploration, underwater communication, and deep-sea resource exploration. They must withstand extreme environments such as high pressure, high salinity, and biofouling for extended periods. Their corrosion resistance directly determines the reliability and service life of the equipment in the kilometer-deep sea. Current technologies typically use titanium alloy shells for sealing, epoxy resin potting, or anti-corrosion coatings to isolate deep-sea transducers from seawater erosion. However, under dynamic pressure changes and long-term operating conditions, the protective structure is prone to leakage due to material fatigue or seal failure.

[0003] Existing deep-sea transducer protection designs still have significant shortcomings. The installation of multi-layered protective components relies on welding or integral molding processes, leading to difficulties in later maintenance or component replacement. Repairs easily damage the original sealing structure. The connection between the protective sleeve and the main body of the equipment is primarily secured with a single flange or clamp, which, under the impact of high-velocity seawater, is prone to thread loosening or sealing strip displacement due to pressure fluctuations, subsequently allowing corrosive media to penetrate. The corrosion protection design of critical interfaces (such as signal transmission terminals and power connections) lacks modular, layered protection, and the contact interfaces between different metals may form electrochemical corrosion loops, accelerating the oxidation failure of the protective tube and the connecting clips. Therefore, we provide a corrosion-resistant deep-sea transducer. Utility Model Content

[0027] like Figure 1-3 As shown, this utility model provides a technical solution: a corrosion-resistant deep-sea transducer, including: an inner sleeve mechanism 1, the inner sleeve mechanism 1 including a transducer 11, a protective cover 12 provided on the outer surface of the transducer 11, a screw cap 13 provided at one end of the protective cover 12, a protective tube 14 provided on one side of the screw cap 13, a mating buckle cap 15 provided on the outer surface of the protective tube 14, and an outer protective mechanism 2 provided on the outer surface of the protective cover 12;

[0028] The outer protective mechanism 2 includes a bottom cover plate 21, an installation tube 22 is provided on the bottom cover plate 21, a connecting sleeve 23 is provided on the outer surface of the installation tube 22, an outer sleeve 24 is provided on one side of the bottom cover plate 21, and a snap-fit ​​block 25 is provided on the outer surface of the outer sleeve 24.

[0029] The inner surface of the protective cover 12 is nested on the outer surface of the transducer 11. One side of the screw cap 13 is fixed to the protective cover 12 by screw rotation. One end of the protective tube 14 is cast onto the screw cap 13. The outer surface of the mating buckle cover 15 is snapped onto the protective tube 14. The bottom cover plate 21 is mated onto the end of the transducer 11 away from the screw cap 13. One end of the mounting tube 22 is cast onto the bottom cover plate 21. The inner surface of the mating sleeve 23 is nested on the outer surface of the mounting tube 22. The outer surface of the outer sleeve 24 covers the outer surface of the protective cover 12. One side of the snap block 25 is cast onto the outer surface of the protective cover 12.

[0030] In this embodiment, when the operator installs and uses the transducer, they can nest the inner surface of the protective cover 12 onto the outer surface of the transducer 11, then fix the screw cap 13 to one end of the protective cover 12 by screw rotation, and one end of the protective tube 14 is cast onto the screw cap 13, while the inner surface of the protective tube 14 is mated to the ground connection pipe of the transducer 11. Finally, the docking buckle 15 is fastened to the protective tube 14 for protection. After installation, the operator can mat the bottom cover plate 21 with the outer sleeve 24 to the end of the transducer 11 away from the screw cap 13, and the mounting tube 22 on the bottom cover plate 21 is cast onto the end of the transducer 11 away from the screw cap 13 and mated with the docking sleeve 23. This isolates the transducer from water during actual use, preventing corrosion and improving its practicality. Example

[0031] like Figure 1-4 As shown, both sides of the bottom cover plate 21 are provided with a snap-fit ​​mechanism 3. The snap-fit ​​mechanism 3 includes a fixing block 31. An inner control plate 32 is provided on one side of the fixing block 31. A spring piece 33 is provided in the inner control plate 32. A snap fastener 34 is provided at one end of the spring piece 33. One end of the fixing block 31 is cast onto the outer surface of the bottom cover plate 21. One end of the inner control plate 32 is cast onto the fixing block 31. One end of the spring piece 33 is welded into the inner control plate 32. The other end of the spring piece 33 is connected to the snap fastener 34. The inner surface of the snap fastener 34 is nested on the outer surface of the snap-fit ​​block 25.

[0032] In this embodiment, to further improve its practicality in actual use, a corresponding fixing block 31 is provided on the outer surface of the bottom cover plate 21, one end of the inner control plate 32 is cast onto the fixing block 31, one end of the spring piece 33 is fixedly connected to the inner control plate 32, and the end of the spring piece 33 away from the inner control plate 32 is cast onto the buckle 34, so that it can be buckled and nested on the buckle block 25, thus further improving its practicality in actual use.

[0033] Working principle:

[0034] like Figure 1-4 As shown, when installing and using this transducer, the inner surface of the protective cover 12 is first nested onto the outer surface of the transducer 11 to ensure a tight fit. Next, the operator secures the screw cap 13 to one end of the protective cover 12 by rotating the screw thread, ensuring the stability of the protective cover 12. One end of the protective tube 14 is then firmly fixed to the screw cap 13 using a casting process, ensuring a secure and reliable connection. The inner surface of the protective tube 14 mates with the connecting pipe of the transducer 11, thereby establishing the connection of the fluid channel.

[0035] Based on this, the workers installed the docking cover 15 onto the protective tube 14 using a snap-fit ​​connection method, further strengthening the protection of the equipment. In this way, the basic installation of the entire transducer is completed, effectively protecting the equipment from the influence of the external environment.

[0036] To enhance the transducer's protection and stability during actual use, the operator then connects the bottom cover plate 21 (with the outer sleeve 24) to the end of the transducer 11 furthest from the screw cap 13. The mounting tube 22 on the bottom cover plate 21 is fixed to the end of the transducer 11 furthest from the screw cap 13 by casting and is connected to the transducer 11 via the mating sleeve 23. This design effectively prevents moisture or other liquids from entering the transducer 11, thus preventing damage due to contact with water or corrosive substances during use, further improving the equipment's service life and reliability.

[0037] Furthermore, to further improve the practicality and stability of the transducer, corresponding fixing blocks 31 are provided on the outer surface of the bottom cover plate 21. During installation, one end of the inner control plate 32 is fixed to the fixing block 31 by casting, while one end of the spring piece 33 is firmly connected to the inner control plate 32. The distal end of the spring piece 33 is connected to the latching device 34 by casting, ensuring that the latching device 34 can smoothly mate with the latching block 25. With this structure, operators can operate more conveniently during installation, and the stability and protection of the device are further enhanced.
