[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 、 Figure 3 and Figure 4, An embodiment provided by the present utility model: A sampling device for detecting oilfield groundwater conditions, including a sampling bin 2. The sampling bin 2 is used for sampling groundwater. The sampling bin 2 can be quickly disassembled and can also temporarily store the sampled groundwater. A guide rod 10 is fixedly connected to the inner wall of the bottom end of the sampling bin 2. The guide rod 10 provides guidance for the movement of the baffle 11. The inner wall of the bottom end of the sampling bin 2 is elastically connected to a baffle 11 through a first spring 9. The baffle 11 seals the bottom inlet of the sampling bin 2 under the elastic force of the first spring 9. When the fixed block on the inner wall of the outer shell 1 prevents the baffle 11 from moving with the sampling bin 2, the baffle 11 compresses the first spring 9. A pressing block 12 is slidably connected to the left inner wall of the sampling bin 2. The pressing block 12 slides on the left inner wall of the sampling bin 2. The movement of the pressing block 12 can drive the movement of the clamping block 13. The left inner wall of the sampling bin 2 is elastically connected to a limiting component through a fifth spring 16.

[0033] Further, a clamping block 13 is elastically connected to the upper inner wall of the sampling bin 2 through a second spring 14. The lower left outer wall of the clamping block 13 is inclined. The clamping block 13 moves upward under the extrusion of the pressing block 12, so that the upper outer wall of the clamping block 13 is clamped on the inner wall of the outer shell 1, fixing the sampling bin 2 in the outer shell 1. One end of the second spring 14 is fixedly connected to the upper inner wall of the sampling bin 2, and the other end of the second spring 14 is fixedly connected to the upper outer wall of the clamping block 13. The outer shell 1 is slidably connected to the upper outer wall of the sampling bin 2. The outer shell 1 is used to drive the movement of the sampling bin 2 and plays a protective role for the sampling bin 2. A semi-circular counterweight block is provided at the bottom end of the outer shell 1. A through bin 7 is fixedly connected to the inner wall of the outer shell 1. When the top ball 8 leaves the bottom opening of the through bin 7, groundwater can enter the sampling bin 2 through the through bin 7. A top ball 8 is elastically connected to the upper inner wall of the through bin 7 through a third spring 6. In the static state, the elastic force of the third spring 6 makes the bottom outer wall of the top ball 8 seal the bottom opening of the through bin 7. When the water pressure is greater than the elastic force of the third spring 6, the top ball 8 leaves the bottom opening of the through bin 7, and groundwater can enter the through bin 7. One end of the third spring 6 is fixedly connected to the upper inner wall of the through bin 7, and the other end of the third spring 6 is fixedly connected to the upper outer wall of the top ball 8. An adjusting component is rotatably connected to the lower inner wall of the outer shell 1.

[0034] Refer to Figure 1 , Figure 2 and Figure 5 , The adjusting component includes a rotating block 3. A through hole and a filter plate are provided on the inner wall of the rotating block 3. The rotating block 3 can be rotated according to the sampling needs. The outer wall of the rotating block 3 is rotatably connected to the lower inner wall of the outer shell 1. A second embedding block 4 is elastically connected to the left outer wall of the outer shell 1 through a fourth spring 5. The setting of the second embedding block 4 can limit the rotating block 3 and fix the position of the rotating block 3 through the second embedding block 4. One end of the fourth spring 5 is fixedly connected to the left outer wall of the sampling bin 2, and the other end of the fourth spring 5 is fixedly connected to the right outer wall of the second embedding block 4.

[0035] Reference Figure 6 Figure 6 , the limiting component includes the first embedding block 15 which is used to fix the position of the pressing block 12. When the pressing block 12 moves to the right, the clamping block 13 moves to the outside of the sampling bin 2 and is clamped on the inner wall of the outer shell 1. The first embedding block 15 is used to fix the position of the pressing block 12. The outer wall of the front end of the first embedding block 15 is elastically connected to the inner wall of the left end of the sampling bin 2 through the fifth spring 16. One end of the fifth spring 16 is fixedly connected to the inner wall of the left end of the sampling bin 2, and the other end of the fifth spring 16 is fixedly connected to the outer wall of the front end of the first embedding block 15.

[0036] Working principle: By pushing the sampling bin 2 into the outer shell 1 from left to right, the fixed block in the sampling bin 2 prevents the baffle 11 from moving, so that the bottom inlet is opened when the sampling bin 2 enters the outer shell 1. At the same time, press the pressing block 12 to the right. Through the extrusion of the pressing block 12, the clamping block 13 moves away from the center and is clamped on the inner wall of the outer shell 1 to fix the sampling bin 2. The first embedding block 15 is clamped on the inner wall of the front end of the pressing block 12 to fix the position of the pressing block 12. According to the needs of sampling, move the second embedding block 4 to release the limit on the rotating block 3 and adjust the position of the rotating block 3. Then, put the sampling device into the groundwater through the connecting rope. When the water pressure is greater than the elastic force of the third spring 6, the top ball 8 leaves through the bottom opening of the through bin 7, and the groundwater can enter the through bin 7. The groundwater enters the sampling bin 2 through the through bin 7 to complete the collection of groundwater.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
