Detailed Description
Example 1
As shown in fig. 1 and 2, one embodiment of the novel columnar mud sampler of the present invention provides a novel columnar mud sampler, which comprises a rod part 1, a non-return device 2 and a sampling pipe 3 from top to bottom; the non-return device 2 is upward in the positive direction, and the lower part of the non-return device is communicated with the sampling pipe 3; the sampling tube 3 is a transparent tubular structure, can be made of organic glass or transparent plastic, and has an opening at the lower part; the rod part is provided with an upper limit structure 4 and a lower limit structure 5, and a collision block 6 is sleeved between the upper limit structure and the lower limit structure. The upper limit structure 4 and the lower limit structure 5 are of a stop block-shaped structure fixedly arranged in the middle section of the rod part 1, and a spring can be adopted to replace the stop block to limit the position of the impact block, which can move up and down. The check device 2 is a single-pass ball check valve, one or a plurality of through holes are formed in the cavity wall of one side, away from the sealing ring, of the ball containing cavity, one or a plurality of axial through holes 21 are formed in the upper portion of the ball containing cavity, the through holes 21 are used for exhausting and draining water when the sampling pipe is inserted into water and moves downwards, after the sampling pipe 3 is exposed out of the water, air can enter the check device 2, and soil in the sampling pipe 3 can be taken out in a labor-saving mode. The upper end and the lower end of the impact block 6 are respectively provided with a groove 7, and the contour lines of the grooves 7 are respectively consistent with the contour lines of the bottom surface of the upper limit structure 4 and the top surface of the lower limit structure 5. When the mud sampler is used, an operator on a ship holds the rod by one hand, and holds the impact block by the other hand to impact the lower limit structure so as to insert the rod into soil. When the sampling tube needs to be taken out, the upper end of the rod part is held by one hand, the impact block is held by the other hand to reciprocate up and down, the impact block continuously impacts the upper limiting structure to enable the mud sampler to obtain the vertically upward force of the rod extending rod, the mud sampler can be taken out smoothly, and when the sampling tube is lifted up, the spherical check valve is enabled to mould negative pressure in the sampling tube to enable sediments in the mud sampler not to fall off due to excessive disturbance. When an operator holds the collision block by hand and lifts up and down in a reciprocating manner, the upper and lower ends of the collision block 6 can respectively wrap the upper limiting structure 4 and the lower limiting structure 5, so that the operator is not easy to clamp hands by the upper and lower limiting structures.
