[0002] Ocean velocimeters are precision instruments used to measure the speed of sound in seawater. They are typically installed on ships, providing accurate data support for ship navigation and seafloor topography mapping, such as depth correction for single-beam echosounders and beam angle correction for multi-beam echosounders. They are widely used in marine scientific research, marine engineering, military reconnaissance, and marine resource exploration. Furthermore, they can be integrated into autonomous navigation platforms such as submarines, AUVs, and ROVs to meet the needs of specialized missions such as deep-sea exploration and resource exploration.

[0003] When the ocean sonic velocity meter is used in seawater, it is susceptible to lateral collisions by marine organisms or debris, which may cause damage to the ocean sonic velocity meter.

[0019] An embodiment of the present application provides an underwater connection protection device for a surface velocity meter. Its main technical solution is to effectively improve the safety and stability of the velocity meter during use by providing an installation shaft 1 and a fixed pipe seat 2, thereby improving the efficiency and accuracy of the velocity meter measurement; and, by providing a traction component, it is convenient for staff to quickly lift the velocity meter from the sea water for maintenance.

[0020] Example: Refer to Figure 1- Figure 3 As shown, an underwater connection protection device for a surface sound velocity meter of this embodiment includes an installation shaft 1 and a fixed pipe seat 2. The installation shaft 1 is fixedly installed on the outer plate 3 of the ship's fairing, and the fixed pipe seat 2 is slidably installed in the middle of the inner side of the installation shaft 1. A nut 5 is provided in the middle of the top of the installation shaft 1; a traction assembly is provided between the nut 5 and the fixed pipe seat 2, including two groups of steel wire ropes 6, the tops of the two groups of steel wire ropes 6 are respectively connected to upper connecting rings 52, and the two groups of upper connecting rings 52 are respectively fixedly installed at the two ends of the inner side of the nut 5, and the middle of the bottom ends of the two groups of steel wire ropes 6 are respectively connected to lower connecting rings 22, and the two groups of lower connecting rings 22 are respectively fixedly installed on both sides of the top of the fixed pipe seat 2.

[0021] During use, the sound velocity meter is first installed into the fixed pipe seat 2, and then the fixed pipe seat 2 is installed to the inner bottom of the installation shaft 1 for use. The installation shaft 1 can limit the fixed pipe seat 2, thereby improving the stability of the sound velocity meter installed inside the fixed pipe seat 2. In addition, by pulling the two sets of steel wire ropes 6, the fixed pipe seat 2 can be pulled upward from the inner bottom of the installation shaft 1 until the fixed pipe seat 2 is taken out from the top of the installation shaft 1, thereby providing convenience for the staff to maintain the sound velocity meter.

[0022] A limiting ring 11 is provided at the inner bottom of the installation shaft 1. When the fixed pipe seat 2 is installed on the inner side of the installation shaft 1, the limiting ring 11 limits and blocks the bottom end of the fixed pipe seat 2. The limiting ring 11 plays a limiting role to prevent the fixed pipe seat 2 from sliding from the bottom of the installation shaft 1. In addition, the setting of the limiting ring 11 and the installation shaft 1 strengthens the stability of the installation of the fixed pipe seat 2.

[0023] The outer wall of the fixed tube base 2 is provided with a plurality of mounting holes 21 , which facilitate fixing the sonic velocity meter installed inside the fixed tube base 2 by fixing screws.

[0024] A short pipe 4 is provided in the middle of the top of the installation shaft 1. The upper end of the short pipe 4 is set as an external thread structure, and the inner wall of the nut 5 is set as an internal thread structure. The nut 5 is threadedly connected to the short pipe 4. The threaded connection structure makes it convenient for the staff to quickly disassemble or install the nut 5.

[0025] In some examples, a through hole 51 is provided in the middle portion of the inner side of the nut 5 . The provision of the through hole 51 facilitates the routing of the circuit of the sonic velocity meter.

[0026] In some examples, the outer surface and inner hole of the fixed tube base 2 are both coated with a second coat of anti-rust paint to enhance the anti-rust performance of the fixed tube base 2 .

[0027] The working principle of this utility model is:

[0028] When using the sound velocity meter, first install the sound velocity meter into the fixed tube seat 2. The fixed tube seat 2 can protect the sound velocity meter and prevent the sound velocity meter from being damaged by lateral collisions of marine organisms or debris when used in seawater. In addition, by installing the fixed tube seat 2 to the inner bottom of the installation shaft 1, the installation shaft 1 can limit the fixed tube seat 2 and prevent the fixed tube seat 2 from shaking in the seawater, thereby effectively improving the stability of the sound velocity meter when in use, and then enhancing the accuracy of the sound velocity meter measurement.

[0029] In addition, a nut 5 is provided at the top of the installation shaft 1, and the nut 5 is connected to the fixed pipe seat 2 by two sets of steel wire ropes 6. By pulling the steel wire ropes 6 upward, the fixed pipe seat 2 can be pulled upward from the inner bottom of the installation shaft 1, so that the sound velocity meter can be quickly lifted and then disassembled, making it convenient for staff to clean plankton or debris adsorbed on the outer surface of the sound velocity meter, thereby improving the convenience of maintaining the sound velocity meter.

[0030] The utility model effectively improves the safety and stability of the sonic velocity meter during use by providing a fixed pipe seat 2 and an installation shaft 1; at the same time, the provision of a traction component makes it convenient for workers to lift and disassemble the sonic velocity meter from seawater, thereby providing convenience for workers to maintain the sonic velocity meter.
