Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the present invention will be further described
[0019] As shown in the figure, a trench opener for laying submarine pipelines in the present invention is mainly composed of a drill bit 1, a knife tooth 2, a rotating shaft 3, a mechanical seal 4, a nozzle 5, an outer casing 6, an inner rod 7 of a push-pull rod, and an outer rod of a push-pull rod. Rod 8, fixed rod 9, filter screen 10, water inlet pipe 11, fixing clip 12, hose 13, inner cylinder 14, inner pump 15, inner pump fixing seat 16, inner cylinder partition 17, waterproof motor 18, connecting member 19. The reducer 20 and the water outlet pipe 21 are composed. The inner cylinder 14 is divided into two independent sealed chambers front and rear by the inner cylinder partition 17. The inner pump 15 is welded to the rear chamber of the inner cylinder through the inner pump fixing seat 16. The inner pump The water inlet pipe 11 protrudes from the rear side of the fixed...

Abstract
The invention discloses a submarine pipeline laying furrow opener, which is suitable for furrowing operation of a hard soil sand seabed with the water depth of 500 meters. The device comprises a drillbit, cutter teeth, a rotating shaft, a mechanical sealing piece, a nozzle, an outer shell, a push-pull rod inner rod, a push-pull rod outer rod, a fixing rod, a fixing clamping piece, a filter screen, a hose, an inner cylinder, an inner pump, an inner pump fixing base, a water inlet pipe, a water outlet pipe, a waterproof motor, a speed reducer and other components; the waterproof motor drives the speed reducer, so that the speed reducer drives the rotating shaft, the cutter teeth and the drill bit to rotate; the special top bifurcated drill bit is adopted, the soil breaking capacity is higher, a push-pull rod controls the operation angle and depth of the furrow opener, seawater pumped by the inner pump is pressurized by the nozzle, high-pressure water can crush hard soil and sand blocksand reduce the furrowing resistance, and the seabed is furrowed in a mechanical and hydraulic jetting composite mode. The submarine pipeline laying furrow opener provided by the invention has the advantages of being good in furrowing effect, high in working efficiency, stable in working state, economical, safe and the like.
Description
technical field [0001] The invention relates to a ditch opener for laying submarine pipelines, which is suitable for ditching operations on hard soil and sand seabeds with a water depth of 500 meters, and belongs to the technical field of marine engineering equipment. Background technique [0002] In the 21st century, human beings have entered a new stage in the development of marine resources, and the scale of offshore oil development and construction has become increasingly large, resulting in the laying of more and more submarine pipelines. Since 1985, CNOOC has built 47 oil and gas fields in different domestic sea areas, and the total amount of submarine pipelines laid is about 3200km. With the continuous development of new oil fields, the total amount of CNOOC's subsea pipelines will also increase significantly. Submarine pipelines are oil and gas transportation tools that connect oil wells and platforms, as well as platforms and onshore storage and transportation faci...
