The working process of the utility model embodiment is as follows:

From the mother ship on the water surface, the jet pumping and dredging integrated ditching equipment is lowered into the water through the spreader; the direction and position of the ditching equipment will deviate to a certain extent in the water due to the influence of waves and currents during the lowering process; at this time, the position of the ditching equipment is repositioned through the driving action of the two propellers on the ditching equipment, and the ditching equipment is accurately placed on the predetermined position on the seabed.

The ditching equipment reaches the bottom of the sea, and after the sliding shoes on both sides contact the seabed soil, the jet pump is started, and the high-pressure jet nozzle starts to spray large flow and high-speed water flow; at the same time, the underwater hydraulic pump fixed on the main frame starts to work, and the second hydraulic push rod pushes the plow body to rotate around the first rotation axis and the second rotation axis, changing the excavation depth of the plow body, realizing the adjustment of the seabed ditching depth, so as to reach the predetermined ditching depth.

During the operation of the ditching equipment, when a relatively hard soil layer is encountered, the high-pressure nozzle on the first spray arm is activated to cut the hard soil with a super-powerful jet of water, so that the plow body of the ditching equipment can quickly ditch and lay cables, and play the role of breaking the soil and ditching in advance.

During the operation of the ditching equipment, when encountering a low-strength soil layer, the high-pressure nozzle on the first spray arm on the plow body will automatically adjust the jet flow velocity and jet direction, thereby effectively reducing the energy consumption during the operation of the ditching equipment.

The left and right sides of the ditching equipment are respectively equipped with two stabilizing down-pressing components. The underwater hydraulic pump generates high-pressure hydraulic oil. The hydraulic oil flows through the hydraulic pipe and flows into the first hydraulic push rod, which drives the down-pressing hook to engage or break away from the soil. When entering the soil, a strong downward pressure load is generated on the sliding shoe, so as to ensure that the trenching equipment is firmly attached to the mud surface of the seabed, produces smooth horizontal sliding, and performs efficient trenching and embedding operations; the meshing ability of the stabilized pressure component to the seabed soil depends on the depth of the stabilized pressure component’s engagement into the soil, and the adjustment of the engagement depth is realized by the extension and shortening of the first hydraulic push rod behind the stabilized pressure component.

During the operation of the ditching equipment, the high-pressure jet nozzle in front of the plow body jet-breaks the soil, and the broken soil and the surrounding seawater form high-density mud; the first suction pipe and the second suction pipe on the top of the plow body can effectively suck the mud formed during the ditching process, and the suction comes from the Venturi tube on the upper part of the plow body. The working principle is as follows: the jet pump 140 of the ditching equipment injects high-speed water flow into the jet inlet of the Venturi tube. The high-speed water flow generates strong suction, and finally sucks out the mud at the bottom of the plow body and discharges it from the mud discharge pipe.

The excavation depth of this trenching equipment is adjustable, which can realize ultra-deep excavation;

The rear part of the ditching equipment is equipped with a stabilizing and pressing component, which can realize the steering function under the premise of ensuring the stability of the equipment;

The front part of the ditching equipment has multiple high-pressure jet nozzles, which can pre-ditch and break the surface of hard soil;

The above descriptions are only illustrative specific implementations of the present utility model, and are not intended to limit the scope of the present utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the protection scope of the present invention.
