Detailed implementation manners

[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the attached drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by showing examples of the present invention.

[0021] As Figure 1 , Figure 2 , Figure 3 shown, the present invention provides a technical solution for a new type of piston-type columnar sediment sampler: including a housing 1, a piston sediment sampling assembly is arranged inside the housing 1, the piston sediment sampling assembly includes a motor 2 installed on the outer wall of the housing 1, the output end of the motor 2 is connected with a turntable 21, the turntable 21 is located inside the housing 1, and a crankshaft 22 is connected to the turntable 21. A linkage column 23 is arranged between the crankshafts 22, a linkage arm 24 is arranged on the linkage column 23, the end of the linkage arm 24 is connected with a piston 27 through a pin shaft, a piston cylinder 29 is arranged outside the piston 27, the piston cylinder 29 is connected with the housing 1, and a sludge suction pipe 30 and a sludge discharge pipe 31 are respectively arranged at the tail end of the piston cylinder 29.

[0022] By driving the turntable 21 to rotate through the motor 2, driving the crankshaft 22 and the linkage column 23 to rotate, enabling the linkage arm 24 to reciprocate, and further driving the piston 27 to reciprocate in the piston cylinder 29. When the piston 27 moves, the sediment is sucked into the piston cylinder 29 through the sludge suction pipe 30, and then the sediment is discharged through the sludge discharge pipe 31, realizing the collection of the sediment.

[0023] One-way valves are arranged inside the nozzles of the sludge suction pipe 30 and the sludge discharge pipe 31, which can prevent the sediment from flowing backward during the collection process, ensuring the integrity and accuracy of the collected samples.

[0024] Multiple groups of linkage arms 24 are arranged on the crankshaft 22, a piston cylinder 29 is arranged outside each group of linkage arms 24, and a sludge suction pipe 30 and a sludge discharge pipe 31 are installed on the piston cylinder 29, which can realize the simultaneous collection of sediments at multiple different depths, improving the representativeness of the collection.

[0025] A clamp 25 is provided on the back of the linkage arm 24. The clamp 25 is connected to the linkage arm 24 by bolts 26 and clamps the linkage column 23 to fix the linkage arm 24 and facilitate the replacement and maintenance of the linkage arm 24.

[0026] A connection seat 11 is provided at the bottom of the housing 1 to facilitate connection to an external device and achieve the fixation and positioning of the overall device.

During the reciprocating motion of the piston 27, sediments are sucked into the piston cylinder 29 through the mud suction pipe 30, and after a period of collection, the sediments are discharged through the mud discharge pipe 31 to achieve the collection of sediments.

[0029] Since multiple groups of linkage arms 24 are provided on the crankshaft 22, and a piston cylinder 29 is provided outside each group of linkage arms 24, sediments at different depths can be collected simultaneously, improving the representativeness and accuracy of the collection. At the same time, the setting of the one-way valve can prevent the backflow of sediments during the collection process, ensuring the integrity and accuracy of the collected samples.

[0030] After the collection is completed, turn off the motor 2, connect the mud discharge pipe 31 to the sample collection device, and discharge and collect the sediments in the piston cylinder 29 through the mud discharge pipe 31.
