Nitrogenized junction box

Abstract

The invention relates to underwater robot operation device, in particular to a nitrogenized junction box which switches a high-voltage electric signal, a low-voltage electric signal at the cable end and an optical fiber signal to a tail wire end of a slip ring to realize the switch of the electric signal. The nitrogenized junction box comprises a box body, a high-voltage terminal, a low-voltage terminal, an optical fiber adaptor and a cover plate; the cover plate is sealed on the box body; one end of the box body is provided with a cable connector for a cable to run through; the other end of the box body is provided with a flange connector for a tail wire of the slip ring to run through; one side of the box body is provided with a charging connector, a pressure limiting valve and a vent plug respectively; the high-voltage terminal and the low-voltage terminal are arranged in the box body in an insulating way respectively; the optical fiber adaptor is arranged in the box body; and a corresponding signals on the cable running through the inside of the junction box are switched to the tail wire of the slip ring through the high-voltage electric signal, the low-voltage electric signal and the optical fiber adaptor. The nitrogenized junction box has the advantages of anti-oxidation, good corrosion resistance, fixed and reliable cable, good sealing effect, good sealing performance, high insulating performance and the like.

Description

technical field [0001] The invention relates to an underwater robot operation device, in particular to a nitrogen-filled junction box that transfers high and low voltage electrical signals and optical fiber signals at the cable end to the tail end of a slip ring to realize the electrical signal transfer. Background technique [0002] An underwater robot is a robot that works in an underwater environment. When an underwater robot performs underwater operations, it must have a power signal and a control signal, so that the robot carrier can complete relevant movements and actions underwater according to instructions. Among them, the transmission and conversion of electrical signals are through high-voltage control cabinets, low-voltage control cabinets, junction boxes, etc., and the power signals and control signals are transmitted to the underwater robot carrier through armored cables, so that the underwater robot carrier can complete the underwater operation. homework tasks....

AI Technical Summary

Problems solved by technology

For the method of transferring between the cable and the slip ring through the cable joint, the cable joint has a low service life, is prone to failure, has poor reliability, and cannot transmit optical fiber signals, and the transmission length is limited. It is only suitable for small and medium-sized underwater robots. Operation; for the way of switching through the junction box, the sealing performance of the existing junction box is poor, especially for the equipment used on board for a long time, the outside humid air is easy to enter the interior of the junction box, resulting in a decrease in the insulation inside the junction box , the system is unstable, and the terminals and joints are easy to oxidize and corrode, which reduces the service life of the terminals and joints, and is prone to electrical failures, reducing the reliability of the system
