[0037] Please refer to Figure 1 and Figure 2 , an oil sample sampling device for a large-diameter shield machine in a preferred embodiment provided by the present invention includes a housing 100, a sampling pump 200, a transition hose 300, and a retaining member 400.

[0038] Two protruding holes 110 are provided on the front side of the housing 100; the sampling pump 200 is installed in the housing 100. The sampling pump 200 has a liquid inlet pipe 210 and a liquid outlet pipe 220, and the liquid inlet pipe 210 and the liquid outlet pipe 220 respectively pass through the two protruding holes 110. One end of the transition hose 300 is connected to the liquid inlet pipe 210. The transition hose 300 can be inserted into the liquid inlet pipe 210 by interference fit or sleeved on the liquid inlet pipe 210. Of course, it can also be connected to the liquid inlet pipe 210 by threading. The transition hose 300 can be made of plastic material and has a certain elastic deformation ability, such as polyethylene, polypropylene, and polyvinyl chloride. For the convenience of sampling, a sampling hose 221 can be connected to the liquid outlet pipe 220. During use, the outer end of the sampling hose 221 extends into the sampling container to collect the oil sample.

[0039] Refer to Figure 4 and Figure 5, the baffle member 400 is connected to one end of the transition hose 300 away from the liquid inlet pipe 210. The contour of the baffle member 400 is larger than the oil extraction port 101, and the baffle member 400 cannot pass through the oil extraction port 101, so it will be blocked outside the oil container 102 and abuts against the outer wall of the oil container 102 corresponding to the oil extraction port 101.

[0040] The oil extraction straight pipe 500 is a straight pipe, and the oil extraction straight pipe 500 is communicated with the transition hose 300 and is used to extend into the oil liquid space. The oil extraction straight pipe 500 can be made of metal or plastic materials.

[0041] A large-diameter shield machine oil liquid sampling device provided by the present utility model utilizes the oil extraction straight pipe 500 to avoid the instability of the sampling height caused by the bending of the pipe body; uses the sampling pump 200 to achieve automatic sampling without manual operation; the transition hose 300 can facilitate the adjustment of the position of the oil extraction straight pipe 500 to insert into the oil extraction port 101, and the contour of the baffle member 400 is larger than the oil extraction port 101, so that the baffle member 400 abuts against the corresponding outer wall of the oil extraction port 101, thereby limiting the insertion depth of the oil extraction straight pipe 500 into the oil extraction port 101, making its position stable, thereby determining the height of the sampling position and realizing fixed-distance sampling.

[0042] In some embodiments of the present utility model, a magnetic attraction member 410 is installed on the baffle member 400, and the magnetic attraction member 410 is used to magnetically attract to the corresponding outer wall of the oil extraction port 101, so that the position of the baffle member 400 is fixed and will not shake easily, making the position more stable during oil extraction.

[0043] Refer to Figure 3 and Figure 5 , in a further embodiment of the present utility model, a plurality of first threaded holes 420 are arranged in a circular array on the baffle member 400, and an adjusting screw 430 is threadedly connected to the first threaded holes 420. The adjusting screw 430 is used to contact the corresponding outer wall of the oil extraction port 101, so as to adjust the height of each adjusting screw 430 to realize the angle adjustment of the baffle member 400, so that when the corresponding outer wall of the oil extraction port 101 is uneven, it can adapt to the uneven contour of the outer wall of the oil extraction port 101. Specifically, a plurality of first threaded holes 420 and adjusting screws 430 are arranged in a circular array.

[0044] Refer to Figure 3 and Figure 5 , in a further embodiment of the present utility model, a central embedding groove 431 is provided in the adjusting screw 430, and the magnetic attraction member 410 is embedded in the central embedding groove 431 to adjust the position along with the adjusting screw 430, so that the magnetic attraction member 410 can adjust the position along with the adjusting screw 430, always approaching the outer wall of the oil container 102 to realize magnetic attraction and ensure the magnetic attraction fixing effect of the baffle member 400. Specifically, the upper end of the central embedding groove 431 is open and the lower end is closed, so as to prevent the magnetic attraction member 410 from falling due to attraction to the outer wall of the oil container 102.

[0045] Referring to Figure 5 , in a further embodiment of the present utility model, a second threaded hole 440 is provided at the center of the retaining member 400. A clamping ring 441 extending radially inward is provided at the upper end of the second threaded hole 440. The end of the transition hose 300 extends into the second threaded hole 440 and is provided with a radially outwardly protruding convex ring 310. During installation, the convex ring 310 can be deformed and contracted to pass through the clamping ring 441 and then return to its original shape after entering the second threaded hole 440. The upper end of the oil extraction straight pipe 500 is provided with an external thread portion 510. The external thread portion 510 is threadedly connected to the second threaded hole 440 and cooperates with the clamping ring 441 to clamp the convex ring 310, thereby realizing the connection and fixation of the oil extraction straight pipe 500, the retaining member 400, and the transition hose 300, simplifying the connection, reducing the use of fasteners, and having a good sealing effect by screwing with the thread.

[0046] Referring to Figure 5 , in a further embodiment of the present utility model, the upper end of the oil extraction straight pipe 500 is provided with a third threaded hole 520 adapted to the external thread portion 510, so that two oil extraction straight pipes 500 can be detachably connected end to end, and thus the connection quantity of the oil extraction straight pipes 500 can be selected according to the oil extraction height.

[0047] Referring to Figure 5 , in a further embodiment of the present utility model, the housing 100 is provided with a temporary storage structure 140 for the oil extraction straight pipe 500 to be clamped and placed. The temporary storage structure 140 is provided with a card slot 141 into which the oil extraction straight pipe 500 can be inserted. One side of the card slot 141 is open for the oil extraction straight pipe 500 to be inserted, and the opening is flared outward, so as to facilitate the insertion of the oil extraction straight pipe 500. The two sides of the card slot 141 are formed by two elastically movable elastic clips 142. When the oil extraction straight pipe 500 is inserted into the card slot 141, the elastic clips 142 can be elastically deformed to allow the oil extraction straight pipe 500 to be inserted into the card slot 141, and the elastic clips 142 can clamp the oil extraction straight pipe 500 inserted into the card slot 141, making the placement of the oil extraction straight pipe 500 stable. Multiple temporary storage structures 140 can be provided to place multiple oil extraction straight pipes 500, and the use quantity of the oil extraction straight pipes 500 can be selected according to needs, which is convenient to use.
