They mainly refer to intelligent systems that replace divers or manned small submarines to perform high-risk underwater operations such as deep-sea exploration, rescue, and mine removal. Therefore, unmanned submersibles are also called "diving robots" or "underwater robots."

[0003] In contrast, the Chinese patent with announcement number CN115042939A discloses a submersible using a winch towline, including a mounting assembly, a bracket assembly, a cable tensioning mechanism, a hoisting mechanism and a towline. A hoisting mechanism is arranged on the deck of a mother ship, a guide wheel is arranged on one side of the mounting assembly, the bracket assembly is rotatably arranged on the mounting assembly, the cable tensioning mechanism is arranged on the bracket assembly, the bracket assembly can rotate and make the cable tensioning mechanism located below the water surface; when the submersible is operating underwater, a towline is connected, the towline passes through the cable tensioning mechanism and the guide wheel on the mounting assembly in sequence and is wound on the hoisting mechanism, and the mother ship provides energy and communication for the submersible operating underwater through the towline; the hoisting mechanism has a braking mechanism, when the submersible leaves the mother ship, the hoisting mechanism synchronously releases the towline, when the submersible approaches the mother ship, the hoisting mechanism synchronously winds and stores the towline, and the cable tensioning mechanism tensions and buffers the towline between the submersible and the mother ship.

[0004] However, the above-mentioned patented optical fiber is designed to be fixed from the outside, which can easily cause the optical fiber to hit obstacles or get entangled in some aquatic plants in the water, affecting the water resistance and movement posture, greatly reducing the safety and accuracy of movement. Therefore, a new device needs to be designed. Summary of the invention

[0005] The purpose of the present invention is to provide a submersible intermediate optical fiber output mechanism in order to solve the above-mentioned problem.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0009] Preferably, the fixed bearing adopts a deep groove ball bearing to ensure smooth rotation.

[0010] Preferably, the transmission shaft is connected to the power motor housing and the submersible body bearing respectively, thereby ensuring flexible rotation of the transmission shaft.

[0011] Compared with the prior art, the beneficial effects are as follows:

[0012] 1. The setting of penetrating through the center of the tail end greatly reduces the possibility of being entangled by water plants and improves the safety of the submersible;

[0013] 2. Through the design of the axis within the axis and the use of internal invisible installation, the appearance is kept neat, the streamlined shape of the submersible is ensured, and the accuracy of movement is improved. BRIEF DESCRIPTION OF THE DRAWINGS
