Abstract

The invention belongs to the field of underwater robots, and particularly relates to an emergency load rejection device for an underwater robot. The torque is transmitted to a load rejection horizontal shaft after a direct current motor is decelerated by a planetary gear reducer, the load rejection horizontal shaft transmits rotary motion to a load rejection vertical shaft through gear transmission, the load rejection vertical shaft transmits rotation to a lead block supporting piece through a rectangular notch, and a rectangular sliding groove is formed between the lead block supporting pieceand a load rejection tray. When the lead block supporting piece rotates to be parallel to the sliding groove of the load rejection tray, a load rejection lead block acts on the lead block supportingpiece through gravity and falls off from the sliding groove, so that the load rejection lead block is separated from a carrier. After the underwater robot discards a part of mass in emergency, the gravity of the underwater robot is smaller than the buoyancy, and therefore the underwater robot can safely float out of the water surface. The device has the advantages of being simple and compact in structure, high in efficiency, easy to control, low in cost, good in underwater sealing performance, capable of being repeatedly used, easy to install and the like.

Description

technical field [0001] The invention belongs to the field of underwater robots, in particular to an emergency dumping device for underwater robots. Background technique [0002] my country is rich in marine resources, and the construction of a marine power is the theme and long-term plan of my country's development. Underwater robot is an automatic control device that can replace people to do certain operations in the ocean environment, and plays an important role in ocean information observation and the development and utilization of ocean resources. The dumping technology is an important part of the underwater robot research, and it is the last safety barrier to prevent the ultra-deep damage or loss of the underwater robot, and plays an important role in the safety performance of the underwater robot. In order to ensure the safety of the underwater robot, when the underwater robot system breaks down, part of the structure is damaged and cannot work normally, the control s...
