[0031] The specific settings and functions of the observation device 4 and the stabilization device 5 are described in detail below.
[0032] like Figure 2 and Figure 3 As shown, the observation device 4 includes a connecting plate 41, the connecting plate 41 is fixedly connected to the shell 1, the surface of the connecting plate 41 is fixedly connected to two slide bars 42, the two slide bars 42 are fixedly connected to the shell 1, the surface of the slide bar 42 is slidably connected to a baffle 43, the surface of the baffle 43 is rotatably connected to a screw 44, the screw 44 is threadedly connected to the connecting plate 41, the surface of the screw 44 is fixedly connected to a handle 45, the surface of the shell 1 is fixedly connected to a glass plate 46, the size of the glass plate 46 is adapted to the size of the baffle 43, the arc surface of the screw 44 is sleeved with a telescopic cover 47, the telescopic cover 47 is rotatably connected to the screw 44, the telescopic cover 47 is rotatably connected to the baffle 43, the baffle 43 will drive the telescopic cover 47 to extend and retract. At this time, the telescopic cover 47 on the screw 44 can protect the screw 44. The surface of the baffle 43 is fixedly connected with a sealing gasket 48, and the sealing gasket 48 is a rubber gasket. The connecting plate 41 will drive the sealing gasket 48 to move towards the direction close to the glass plate 46. At this time, the sealing gasket 48 made of rubber material can increase the sealing between the baffle 43 and the glass plate 46. The surface of the glass plate 46 is fixedly connected with a scale plate 49, and the surface of the scale plate 49 is provided with a scale bar. The amount of sampling can be determined by observing the scale plate 49 on the glass plate 46. At this time, the scale plate 49 can facilitate the staff to observe the amount of sampling.
[0033] like Figure 2 and Figure 4 as well as Figure 5As shown, the stabilizing device 5 includes a fixing frame 501, the fixing frame 501 is fixedly connected to the outlet pipe 2, the surface of the fixing frame 501 is rotatably connected to a bidirectional screw rod 502, the arc surface of the bidirectional screw rod 502 is threadedly connected to two push plates 503, the surfaces of the two push plates 503 are fixedly connected to push rods 504, the surfaces of the push rods 504 are fixedly connected to arc plates 505, the surfaces of the push plates 503 are fixedly connected to support rods 506, the surfaces of the support rods 506 are fixedly connected to sliders 507, the surfaces of the sliders 507 are slidably connected to slide rails 508, the slide rails 508 are fixedly connected to the outlet pipe 2, and the surfaces of the sliders 507 are fixedly connected to the outlet pipe 2.

[0034] Working principle: After geological sampling of the oil well, when it is necessary to observe the sampling volume in the sampler, it is necessary to first turn the handle 45. At this time, the handle 45 will drive the screw 44 to rotate along the surface of the baffle 43. At the same time, the screw 44 will rotate along the surface of the connecting plate 41 with the help of its own thread. At this time, the screw 44 will drive the baffle 43 to move in the direction close to the connecting plate 41, and then the baffle 43 will drive the telescopic cover 47 to retract. At this time, the telescopic cover 47 on the screw 44 can protect the screw 44. Then the baffle 43 slides along the surface of the slide rod 42. At the same time, when the baffle 43 is close to the connecting plate 41, the glass plate 46 fixed on the shell 1 will be displayed. Then, by observing the scale plate 49 on the glass plate 46, the amount of sampling can be determined. At this time, the scale plate 49 can facilitate the staff to observe the amount of sampling. When the observation is finished, the handle 45 can be rotated in the reverse direction. At this time, the handle 45 will drive the screw 44 to rotate. At the same time, the screw 44 drives the baffle 43 to move away from the connecting plate 41 by its own thread, and then the connecting plate 41 will drive the sealing gasket 48 to move towards the glass plate 46. At this time, the sealing gasket 48 made of rubber can increase the sealing between the baffle 43 and the glass plate 46. By setting up the observation device 4 and utilizing the mutual cooperation between the connecting plate 41, the sliding rod 42, the baffle 43, the screw 44, the handle 45 and the glass plate 46, it is not necessary to pour the sample in the sampler into the container to observe the sampling amount, thereby avoiding the situation that the sample in the sampler is contaminated and oxidized when being poured out for observation, resulting in errors in the sample detection data, thereby improving the protection of the sample and further improving the accuracy of the sample detection.
[0035] When the hook is hung into the pull ring 3 and the sample is lowered, the bidirectional screw rod 502 is first rotated, and then the bidirectional screw rod 502 will rotate along the surface of the fixed frame 501, and then the bidirectional screw rod 502 will use its own thread to drive the two push plates 503 to move in the direction of approaching each other, at this time, the push plate 503 will drive the push rod 504 to move, and then the push rod 504 will drive the arc plate 505 to move, and at the same time, the push plate 503 will drive the anti-skid protrusion 510 to move. At this time, when the anti-skid protrusion 510 is in close contact with the hook, the anti-skid protrusion 510 can increase the friction between the arc plate 505 and the hook, and then the push plate 503 will drive the support rod 506 to move, and at this time, the support rod 506 will drive the slider 507 The slider 507 slides along the surface of the slide rail 508, and at the same time, the slider 507 drives the ball 509 to move along the surface of the slide rail 508. At this time, the ball 509 can reduce the friction between the slider 507 and the slide rail 508. By setting the stabilizing device 5, using the mutual cooperation among the fixed frame 501, the two-way screw rod 502, the push plate 503, the push rod 504, the arc plate 505, the support rod 506, the slider 507 and the slide rail 508, it can be achieved that when the hook is hung into the pull ring 3, the hook is firmly stabilized in the pull ring 3, avoiding the situation that the hook shakes and falls off after being hung in the pull ring 3, which causes the sampler to fall off, thereby improving the stability between the hook and the pull ring 3, and further stabilizing the sampler.
