Embodiment Construction

[0034] The specific embodiment of the present invention is shown in the accompanying drawings. The underwater oil pumping device includes: oil suction pipe 1, outer cylinder end cover 2, hydraulic cylinder end face fixing flange 3, hydraulic cylinder 4, outer cylinder 5, oil suction pipe locking Block 6, slewing support fixed flange 7, inner toothed turntable bearing outer ring 8, inner toothed turntable bearing inner ring 9, connecting screw 10, flange 11, oil seal 12, water jet nozzle and holder 13, lip The sealing ring 14, the rotating block 15, the motor fixing seat 16, the fixing screw 17, and the motor 18 are characterized in that: the flange 11 connects the whole set of devices with the ship wall to be drilled. After the meshing of the inner ring 9 of the turntable bearing decelerates, the rotating block 15 is driven to rotate. The water jet nozzle and the holder 13 fixed on the rotating plate also complete the rotating hole opening movement. After the hole opening is co...

Abstract

The invention relates to a water-jet-based underwater tapping and pumping unit and relates to the field of recycling of oil spill from shipwrecks, in particular to a tapping and pumping unit for underwater residual oil chambers of shipwrecks. The water-jet-based underwater tapping and pumping unit comprises a connecting supporting mechanism, a tapping mechanism, a pumping mechanism, seals and a motor; the tapping mechanism and the pumping mechanism are mounted on the connecting supporting mechanism; the motor is mounted on the connecting supporting mechanism and is connected with the tapping mechanism so as to drive the same to rotate to carry out tapping; the tapping mechanism and the connecting supporting mechanism are sealed via the seal; the pumping mechanism and the connecting supporting mechanism are sealed via the seal; the connecting supporting mechanism is connected with a shipwreck to be pumped. The water-jet-based underwater tapping and pumping unit has the advantages of novel structure, good processing simplicity, excellent cutting quality, good applicability, wide cutting range, good cleanliness and environmental friendliness and the like; therefore, the water-jet-based underwater tapping and pumping unit is a novel water-jet-based underwater tapping and pumping unit having both good economy and practicality.

Description

technical field [0001] The underwater perforated oil pumping device based on water jets of the present invention relates to the field of recovery of oil spilled from sunken ships, and in particular is a perforated oil pumping device for underwater residual oil tanks of sunken ships. Background technique [0002] With the rapid development of the shipping industry in recent years, the number of ships has increased significantly, and the risk of ship sinking has also increased. Timely pumping the residual oil in the sunken ship to a safe ship can effectively prevent oil spill pollution and reduce damage. [0003] At present, traditional mechanical drilling machines are mostly used in our country to recover the residual oil in the residual oil tank of sunken ships. The transmission mechanism is complex, the monitoring and control are inconvenient, and it mainly relies on divers for underwater operation, which is relatively low in safety. [0004] Water jet cutting technology, c...
