Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a sampling device for environmental protection testing.

[0025] This utility model provides, for example Figure 1-4 An environmental testing sampling device is shown, including a top frame 1, a movable frame 2 that slides through the top frame 1, two symmetrically arranged sleeves 3 that are fixedly inserted through the left side of the movable frame 2, a first sampling tube 4 that is fixedly inserted through the lower end of the sleeves 3, a piston 5 that slides through the first sampling tube 4, a pull rod 6 that is fixedly inserted through the top of the piston 5, a limiting cylinder 7 that is fixedly inserted through the right side of the movable frame 2, a movable tube 8 that slides through the limiting cylinder 7, a second sampling tube 9 that is threaded through the lower end of the movable tube 8, the movable tube 8 being an internally threaded tube, and a connecting thread on the upper end of the second sampling tube 9. The bottom inlets of the first sampling tube 4 and the second sampling tube 9 are both tapered.

[0026] Both the top of the pull rod 6 and the moving tube 8 are fixedly provided with I-shaped blocks 10. The upper part of the top frame 1 is slidably provided with a push rod 11. The bottom of the push rod 11 is fixedly provided with a card plate 12 that is slidably fitted with the I-shaped block 10. The top of the push rod 11 is fixedly provided with a pull ring 13.

[0027] When performing liquid sampling, the moving frame 2 is moved laterally, so that the two first sampling tubes 4 on the left side move to the lower end of the push rod 11. During the movement of the moving frame 2, the I-shaped block 10 slides stably into the clamping plate 12. At this time, under the connection of the push rod 11 and the pull ring 13, the piston 5 can move in the first sampling tube 4. Under the action of air pressure, the external gas or liquid sample can quickly enter the first sampling tube 4 to complete the sampling.

[0028] When soil sampling is performed, the moving frame 2 is moved in the opposite direction so that the second sampling tube 9 is located below the push rod 11. At this time, the push rod 11 is pushed down, causing the second sampling tube 4 to move down and insert into the ground. Under the compression of the conical area inside the second sampling tube 4, the soil sample enters the second sampling tube 9.

[0029] In order to enable the movable frame 2 to slide stably inside the top frame 1, such as Figure 1-2 As shown, slide rail plates 14 are fixedly provided on both sides of the inner wall of the top frame 1, and slide grooves 15 are provided on both sides of the outer wall of the movable frame 2. The slide rail plates 14 are slidably disposed in the slide grooves 15. Two symmetrically arranged limiting rods 16 are fixedly provided on the side of the limiting cylinder 7. Two symmetrically arranged limiting grooves 17 are provided on the outer wall of the movable tube 8. The limiting rods 16 are slidably disposed in the limiting grooves 17.

[0030] With the sliding cooperation of the slide rail plate 14 and the slide groove 15, the moving frame 2 can slide stably in the top frame 1, while the cooperation of the limiting groove 17 and the limiting rod 16 enables the second sampling tube 9 to move down stably and sample the soil.

[0031] In order to determine the position of multiple sampling tubes after they have been moved, such as Figure 1 and Figure 3 As shown, the top of the movable frame 2 has a groove, and the inside of the groove is a pressure plate 18. The top of the pressure plate 18 is fixedly provided with a plurality of spaced insertion rods 19. The bottom of the inner wall of the groove is fixedly provided with a support rod 20. The support rod 20 slides through the inside of the pressure plate 18. The rod wall of the support rod 20 is fitted with a spring 21. The two ends of the spring 21 are fixedly connected to the support rod 20 and the pressure plate 18 respectively. The top of the top frame 1 has a plurality of insertion holes 22 for inserting the insertion rods 19.

[0032] Before sampling, the pressure plate 18 is pressed down, causing it to move along the support rod 20 and stretch the spring 21. At this time, the insertion rod 19 is pulled out from the insertion hole 22. Then the moving frame 2 starts to move. After the moving frame 2 drives the first sampling tube 4 or the second sampling tube 9 to be fixed in position, the pressure plate 18 is released. Under the elastic force of the spring 21, the insertion rod 19 rebounds and continues to be inserted into the insertion hole 22, thus completing the fixation of the position of the moving frame 2 and the sampling tube, ensuring that the sampling work is carried out stably.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
