Problems solved by technology
However, this kind of equipment itself does not have a power system, and it needs to be operated by rigid connection of the ship-borne cables. The movement of the grab must be realized by adjusting the position of the ship, which cannot meet the requirements for precise positioning of the underwater track; Avoid ground collision with the towing body, which is easy to cause damage to the grab itself; in addition, due to the long distance of information transmission, the commonly used coaxial cable as the transmission medium is easy to attenuate during the transmission process, which is not suitable for video signals and control signals of deep-sea grabs transmission; therefore, the existing TV grabs are generally effective in deep sea operations

The invention relates to a deep sea two-way propulsion hydraulic grab monitoring system. The system comprises a water control device arranged in an operation room of a grab tugboat and used for monitoring a hydraulic grab; an underwater driving box respectively provided with two-way propellers at two ends, communicated with the water control device through an optical fiber, connected with the grab tugboat through a drag cable and used for precisely positioning the hydraulic grab and processing and transmitting monitoring information; the hydraulic grab connected with the underwater driving box and hydraulically driven through the underwater driving box; and a grab sensing device communicated with the underwater driving box through an optical fiber, connected with the underwater driving box through a drag cable and used for monitoring the hydraulic grab, acquiring the monitoring information and transferring the monitoring information to the underwater driving box. Compared with the prior art, the deep sea two-way propulsion hydraulic grab monitoring system has such advantages as comprehensive monitoring information, precise positioning and high communication quality.
Description
technical field [0001] The invention relates to the field of deep sea exploration, in particular to a deep sea two-way propulsion hydraulic grab monitoring system. Background technique [0002] The grab is an important pick-up tool for grabbing goods. It is widely used in port loading and unloading operations, especially in the field of grabbing bulk cargo, such as coal loading and unloading, ore loading and unloading. At the same time, the grab is also an underwater An essential tool for operations such as resource sampling and channel dredging. [0003] According to research, there are abundant natural resources in the deep sea, and most of them are in a primitive and undeveloped state. How to exploit these precious resources is a subject of competing research by various countries. In the context of the country's vigorous development of marine engineering, the research on the deep-sea sampling grab system has important strategic significance. At present, deep-sea hydraul...
