Opposite-flushing module, opposite-flushing type high-pressure water jet trencher and operation method of opposite-flushing type high-pressure water jet trencher

Abstract

The invention discloses an opposite-flushing module, an opposite-flushing type high-pressure water jet trencher and an operation method of the opposite-flushing type high-pressure water jet trencher. Under the control of an underwater cable robot, the opposite-flushing type high-pressure water jet trencher moves vertically and horizontally by means of a vertical propeller and a horizontal propeller of the cable robot, the movement is flexible, and the trencher can conveniently and quickly reach an operation site; a high-pressure jet flow mechanism operates, trenching operation is conducted after the diameter, the distance and the water jet flow direction of small nozzles are adjusted, meanwhile, an opposite-flushing mechanism operates synchronously, the spraying direction of large-flow nozzles is adjusted through a direction adjusting rudder plate so as to balance the counter-acting force brought by the high-pressure jet flow mechanism; and finally, continuous trenching operation is achieved in cooperation with crawler wheels. By additionally arranging the adjustable opposite-flushing mechanism, reacting force generated by water jet is counteracted, and the problem that the reacting force generated by high-pressure water jet during trenching seriously affects the trenching operation efficiency and the operation stability is solved.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a hedging module, a hedging high-pressure water jet trenching machine and an operation method. Background technique [0002] With the development of society and economy, the value of the ocean has been paid more and more attention by human beings. Especially in today's increasingly scarce resources, the significance of ocean development and utilization is more prominent. There are various resources such as manganese, coal and oil in the ocean. At the same time, the marine ranch has become more and more prosperous in recent years, and the trenching technology, which is an important part of the ocean engineering technology field, has become increasingly mature. [0003] Among them, the design of the trenching machine directly affects the quality of trenching. Most trenchers today are relatively heavy and not very maneuverable in the water. The applicant foun...
