[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a convenient oil pipeline connection mechanism for sampling in oil extraction, comprising an oil pipeline 1 and a sampling tube 2. The sampling tube 2 is located below the oil pipeline 1 and communicates with the interior of the oil pipeline 1. The outer surface of the sampling tube 2 is threaded with a thread 3. A control disc 4 is threadedly connected to the outer surface of the sampling tube 2 via the thread 3. A displacement disc 5 is rotatably connected to the lower surface of the control disc 4. A vertical rod 6 is fixedly connected to the lower surface of the displacement disc 5. A bearing disc 7 is fixedly connected to the lower end of the vertical rod 6. A sampling cylinder 8 is provided on the upper surface of the bearing disc 7. An extension extending from the lower surface of the bearing disc 7 is provided on the upper surface of the bearing disc 7. The first sliding groove 9 on the side surface and the upper side surface of the bearing plate 7 have two second sliding grooves 10 extending to their lower side surfaces. The sliding block 11 is slidably connected inside the first sliding groove 9. The upper side surface of the sliding block 11 is fixedly connected to an L-shaped fixing plate 12. The side surface of the L-shaped fixing plate 12 near the axis of the bearing plate 7 is fixedly connected to an arc-shaped clamping plate 13. The first sliding groove 9 is provided with a fixing component. When sampling with the sampling tube 8, the arc-shaped clamping plate 13 can easily complete the clamping, fixing and positioning operations, which greatly reduces the difficulty of placing and installing the sampling tube 8 and improves the speed of its placement.
[0024] Furthermore, the fixing assembly includes a limiting rod 14, which is fixedly connected to the inner wall of the first sliding groove 9. A sliding block 11 is slidably sleeved on the outer surface of the limiting rod 14. A rubber pad 15 is adhered to the side of the arc-shaped clamping plate 13 near the axis of the bearing disk 7. A spring 16 is fixedly connected to the side of the sliding block 11 near the axis of the bearing disk 7. The end of the spring 16 is fixedly connected to the inner wall of the first sliding groove 9. The first sliding groove 9 communicates with the interior of the second sliding groove 10. A driving block 17 is slidably connected inside the second sliding groove 10, and the driving block 17 is fixedly connected to the sliding block 11. Two rollers 18 are provided on the side surface of block 17 away from the axis of the bearing disk 7. A limiting sleeve 19 is fixedly connected to the outer surface of the sampling tube 2. The vertical rod 6 is slidably sleeved inside the limiting sleeve 19. A drive plate 20 is fixedly connected to the surface of the limiting sleeve 19. The side surface of the drive plate 20 near the axis of the bearing disk 7 is inclined. The drive plate 20 extends into the interior of the second sliding groove 10. The rising of the bearing disk 7 can be used to cooperate with the fixedly installed drive plate 20, so that the rising docking of the sampling tube 8 and the clamping and positioning of the sampling tube 8 can be completed with only one operation, which greatly simplifies the operation steps.
[0025] The drive plate 20 mentioned in the text does not contact the second sliding groove 10.
[0026] Working principle: When sampling oil inside the oil pipeline 1, the sampling cylinder 8 is first placed on the upper surface of the support plate 7. Then, by rotating the control plate 4, which is threaded to the outer surface of the sampling tube 2, the control plate 4 will move vertically. This movement of the control plate 4 drives the displacement plate 5. Since the vertical rod 6 on the displacement plate 5 is restricted in its movement trajectory by the limiting sleeve 19, and the displacement plate 5 is rotatably connected to the control plate 4, the movement of the control plate 4 will drive the displacement plate 5 to move vertically. The movement of the displacement plate 5, in turn, uses the vertical rod 6 to synchronously drive the support plate 7 and the sampling cylinder 8. Simultaneously, due to the limiting sleeve 19... The drive plate 20 connected to 9 cannot move, so the drive plate 20 and the bearing plate 7 form a movement difference, causing the inclined surface of the drive plate 20 to contact the roller 18 on the drive block 17, thereby squeezing the drive block 17 to move towards the axis of the bearing plate 7. When the drive block 17 moves, it will drive the sliding block 11 to move synchronously. When the sliding block 11 moves, its movement trajectory is restricted by the limit rod 14. When the sliding block 11 moves, it will also compress the spring 16 and drive the L-shaped fixing plate 12 to move. When the L-shaped fixing plate 12 moves, it will drive the arc-shaped clamping plate 13 to move synchronously. After the arc-shaped clamping plate 13 moves, it will position and calibrate the sampling tube 8. At this time, sampling can be completed by opening the valve on the sampling tube 2.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
