Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 The present invention provides a technical solution: a comprehensive test rotating device for an underwater optical fiber slip ring 5, comprising a rotating shaft 10, a driving motor being connected to the lower end of the rotating shaft 10, a slip ring fixing tool 4 being detachably mounted on the upper end of the rotating shaft 10, an optical fiber slip ring 5 being fixedly mounted on the slip ring fixing tool 4, a rotor portion on the optical fiber slip ring 5 being detachably connected to the slip ring fixing tool 4, a lower plate 2 being fixedly connected to the lower portion of the rotating shaft 10, an outer shell 7 being fixedly connected to the lower plate 2, an upper plate 6 being fixedly connected to the upper end of the outer shell 7, a pressure port 8 being provided on the upper plate 6 and communicating with an inner cavity of the outer shell 7, an inner cavity of the slip ring fixing tool 4 being communicated with an inner cavity of the outer shell 7, during testing, the inner cavity of the outer shell 7 is filled with liquid, and internal pressurization can be performed through the pressure port 8.

[0025] The present invention, through the provision of the slip ring fixing fixture 4, can be conveniently and quickly fixedly installed with the rotor part of the optical fiber slip ring 5 to be tested, so that the driving motor drives the slip ring fixing fixture 4 and the optical fiber slip ring 5 to be tested to rotate synchronously through the rotating shaft 10; through the provision of the outer shell 7 and the pressure port 8, the liquid used for testing can be introduced into the inner cavity of the outer shell 7 to simulate the underwater application scenario of the optical fiber slip ring 5 to be tested; at the same time, the pressure inside the outer shell 7 and the slip ring fixing fixture 4 can be increased through the pressure port 8, so as to test the comprehensive performance of the optical fiber slip ring 5 to be tested under the high water pressure environment.

[0026] Reference Figure 2 As shown, in this embodiment, the slip ring fixing tool 4 includes a sleeve 41 and a cap-shaped member 42 fixedly connected to the sleeve 41. The sleeve 41 is connected to the outer shell 7 through a connecting hole 9. The upper end of the sleeve 41 is fixedly connected to the rotor part of the optical fiber slip ring 5. The cap-shaped member 42 is fixedly arranged at the lower end of the sleeve 41. A connecting sleeve 43 is fixed on the cap-shaped member 42. The outside of the connecting sleeve 43 is detachably connected with a clamping joint 3, and the clamping joint 3 is fixedly connected to the rotating shaft 10. Through the connecting sleeve 43 and the clamping joint 3, after being fixedly connected to the rotor part of the optical fiber slip ring 5 to be tested through the sleeve 41, the connecting sleeve 43 is fixedly connected to the clamping joint 3, and then the clamping joint 3 and the optical fiber slip ring 5 to be tested are driven by the driving motor to rotate synchronously, so as to subsequently change the rotation speed of the optical fiber slip ring 5 to be tested and test the application performance of the optical fiber slip ring 5.

[0027] In this embodiment, a connecting flange 1 is fixedly provided at the lower end of the rotating shaft 10 , and is fixedly connected to the output shaft of the driving motor via the connecting flange 1 .

The sealing groove 12 and the sealing ring can effectively ensure the sealing of the inner cavity of the outer shell 7, and further ensure that when the outer shell 7 is internally pressurized through the pressure port 8, the pressure is prevented from leaking out, which causes a large error in the test data.

The setting of the limiting post 11 can effectively limit the rotation of the stator part of the entire optical fiber slip ring 5 to be tested, and at the same time facilitate the subsequent rapid disassembly or installation of the entire optical fiber slip ring 5, thereby improving the test efficiency.

[0030] Reference Figure 5 As shown, in this embodiment, during the test, the upper end of the optical fiber slip ring 5 is connected to the circulator for transmission, and the lower end of the slip ring is connected to the reflector for transmission. In the actual test, the entire rotating device drives the optical fiber slip ring 5 in the inner cavity of the outer shell 7 to rotate through the motor, and the pressure in the inner cavity of the outer shell 7 is adjusted by cooperating with the pressure-pressing port 8 in the pressure adjustment assembly; at the same time, the temperature of the inner cavity of the box is adjusted through the high and low temperature test box. Finally, the test data is obtained through the optical power meter to test the comprehensive application performance of the optical fiber slip ring 5 to be tested in underwater environments with different temperatures, rotation speeds and pressures.
