Description

technical field [0001] The invention relates to a high-pressure water jet device, in particular to a high-pressure water jet device for breaking deep-sea cobalt crusts. Background technique [0002] With the depletion of land resources, the development of deep sea resources has become an international trend. Deep-sea cobalt crust is a polymetallic mineral rich in metallic cobalt. In view of the economic value and strategic significance of cobalt crusts, the development of deep-sea cobalt crust resources has become the consensus of many developed countries. Due to the uneven thickness of the deep-sea cobalt crust, it is necessary to detect the thickness of the cobalt crust in real time in order to determine the cutting depth of the tool in actual mining. The existing mining technology has problems such as low cutting efficiency, high impact load, difficulty in real-time control of the cutting depth of cobalt crust, and unstable output pressure of the power output device. ...
