Problems solved by technology

[0002] For sampling shallow seabed sediments within 10 meters, if a single drill pipe is used to drill, the pipe is too long to be unfavorable for launching and hoisting by the exploration ship; The sample quality deteriorates. If a hose auger is used for sampling, it can facilitate the sampling of shallow seabed sediments, but how to drive the hose forward and backward more effectively requires a new technology to achieve

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] The structural reference of the seabed sediment serpentine drilling equipment applying the seabed sediment serpentine drilling drive device 3 of the present invention figure 1 As shown in -4, a hose 4 is spirally wound in the spiral channel between the inner and outer walls of the drum 2, and the hose 4 is driven by the seabed sediment serpentine drilling power device 3 to drill and sample at one time.

[0019] Wherein, the drum 2 is installed on the frame 1, the drum has a double-layer structure, and a helical channel 21 with a helical groove is formed on the inner wall, and the hose used for sampling is helical and placed in the helical groove , and is restricted on the outside by the outer wall to prevent escape from the helical groove;

[0020] The afterbody of described flexible pipe 4 connects the sampling device 5 that uniform el...

Abstract

The invention provides a seabed sediment snake-like drilling driving device, which comprises a driving pipe sleeve (35) used for pushing a hose (4) to move forwards in a spiral channel in a spiral mode and pulling the hose (4) to move back in the spiral channel in a spiral mode, and the driving pipe sleeve (35) is installed below a rotary driving ring (34) fixed to a gear ring (34). The driving ring (34) is suspended below a supporting plate (32) which can be driven to horizontally ascend and descend along a vertically-arranged guide rod (7), the inner side of the gear ring (34) is meshed witha pair of driving gears to form a gear pair, the driving ring (34) is driven to rotate through transmission of the driving gears, and therefore the hose (4) is driven to rotationally move forwards orretract in the spiral channel. The device is simple in structure and reliable in work.

Description

technical field [0001] The invention relates to the technical field of seabed shallow sediment sampling, in particular to a seabed sediment serpentine drilling drive device. Background technique [0002] For sampling shallow seabed sediments within 10 meters, if a single drill pipe is used for drilling, the pipe is too long to be hoisted by the exploration ship; if the drill pipe is drilled in sections, the sediment sample will be faulted and cause The quality of the sample deteriorates. If a hose auger is used for sampling, it can facilitate the sampling of shallow seabed sediments. However, how to drive the hose forward and backward more effectively requires a new technology to achieve it. Contents of the invention [0003] The object of the present invention is to provide a driving device for serpentine drilling of seabed sediments in order to overcome the above-mentioned defects of drill pipe sampling. [0004] For realizing the purpose of the present invention, the t...
