Hydraulic chain saw of deep sea manned submersible vehicle

Abstract

The invention discloses a hydraulic chain saw of a deep sea manned submersible vehicle. The hydraulic chain saw mainly comprises a sealing shell, a hydraulic motor, an upper baffle, a lower baffle, connecting keys, a saw plate, a cutting chain and an impingement plate. The hydraulic motor is fixed in the sealing shell through a flange, and after being clamped, the upper baffle and the lower baffle are fixed to the front end of the sealing shell. Sliding grooves are formed in the corresponding positions of the upper baffle and the saw plate. The clamping keys are provided with transverse keys and springs. The connecting keys penetrate the sliding grooves of the upper baffle and the saw plate to fix the saw plate to the position between the upper baffle and the lower baffle, and clearance fit connection is achieved. An output shaft of the hydraulic motor is connected with a spline shaft through a coupler, and the spline shaft penetrates a front end cover of the sealing shell and the lower baffle. A chain wheel is fixed to the front end of the spline shaft, and the cutting chain is wound on the chain wheel and the saw plate. The impingement plate is arc and is hinged to the side face of the lower baffle through a connecting rod. The hydraulic chain saw is loaded in a submersible vehicle sampling basket. The hydraulic chain saw is easy to operate, convenient to maintain, safe and reliable.

Description

technical field [0001] The invention relates to a deep-sea rock sampling device, in particular to a hydraulic chain saw for a deep-sea manned submersible. Background technique [0002] The total area of ​​the world's oceans is about 361 million square kilometers, and there are extremely rich mineral resources in the seabed crust, such as polymetallic nodules, cobalt-rich crusts, polymetallic sulfides and other ore resources. At this stage, land resources are increasingly depleted, and humans are increasingly Emphasis is placed on the development and utilization of deep-sea mineral resources. From June 15 to 20, 2012, the "Jiaolong" manned submersible completed a 7,000-meter-level sea trial. The maximum diving depth is 7062 meters. The success of the 7,000-meter sea trial marks China's ability to carry out scientific research and resource exploration in 99.8% of the world's ocean depths. For the sampling of the seabed, most of the seabed core sampling machines are used for ...

AI Technical Summary

Problems solved by technology

Looking at the research status at home and abroad, the coring tools developed abroad that can be used for loading are all special tools, which do not match the interface of the Jiaolong manned submersible in my country; the 7000m cobalt crust drilling rig developed in China has not been realized due to various reasons. The matching operation of the Jiaolong submersible is not only heavy, but due to the limitation of the structure and working method of the core sampler, the phenomenon that the drill bit is stuck in the ore is prone to occur, which is prone to danger; and because the drill bit has a tubular structure, the ore sample taken out The shape and size cannot be adjusted independently, and further upgrading and optimization are needed, and there are no relevant reports in practical applications

[0003] In summary, the existing ore sampling equipment in the deep sea environment has problems such as difficult sampling, complex structure, low cutting depth, and complicated operation.
