Abstract

The invention belongs to the technical field of submarine observation monitoring, and relates to a release device for submarine environment observation monitoring and a submarine environment observation monitoring system. The discarded counterweight is distributed on the periphery of the submarine detection equipment, and counterweight pull ropes are distributed on the periphery of the submarine detection equipment, so that the purpose of arranging the submarine detection equipment in the central area of the bottom of the device is achieved, the deep-sea distribution recycling requirement of the device can be guaranteed, the sitting-bottom observation of the submarine detection equipment can be realized, and the key effect is achieved for meeting the observation and monitoring requirement of the sea water and submarine interface. Each counterweight pull rope is penetrated in the rope guide tube at the corresponding position, so that the counterweight pull ropes are not mutually interfered in the releasing process and are not pulled by other parts. The main body frame and the columnar mounting frame are integrally hollow frames, the middle part and the bottom of the middle part of the frame are completely vacant due to the inclined pull avoidance of the counterweight stay rope, and the functions of cabin bodies, sensors, other measuring devices and the like can be arranged, so that the observation and monitoring functions of a submarine interface can be expanded.
