[0026] The two adjacent zero buoyancy sealed photoelectric composite cables 1 are connected through the explosion-proof photoelectric composite slip ring 6 or through the plug-in assembly. The zero buoyancy sealed photoelectric composite cable 1 at one end is connected to the robot through the plug-in assembly, and the zero buoyancy sealed photoelectric composite cable 1 at the other end is connected to the photoelectric remote control cabinet 11 through the plug-in assembly.

[0027] The explosion-proof junction box 7 is arranged outside the connection between the zero buoyancy sealed photoelectric composite cable 1 and the explosion-proof photoelectric composite slip ring 6. The plug-in assembly comprises an explosion-proof photoelectric sealed connector plug and an explosion-proof photoelectric sealed connector socket.

At the connection position between the explosion-proof photoelectric sealing connector plug and the zero-float sealing photoelectric composite cable 1, the explosion-proof photoelectric sealing connector plug adopts a sealing filler type cable entry device to realize the explosion-proof effect.

[0033] As a possible example, in the embodiment, the plug-in assembly is threadedly connected with the robot, and the connection position is sealed by a sealing ring to improve the sealing property of the connection position.

[0034] As a possible example, in the embodiment, inside the explosion-proof junction box 7, the optical fiber connection position between the zero-float sealing photoelectric composite cable 1 and the explosion-proof photoelectric composite slip ring 6 adopts an optical fiber adapter 8 for connection, and the wire connection position between the zero-float sealing photoelectric composite cable 1 and the explosion-proof photoelectric composite slip ring 6 adopts an electrical terminal for connection.
