[0027] Please refer to Figures 1-4

[0028] Example 1: A sampling device for soil petroleum hydrocarbon pollution, including a support bottom plate 1. Movable wheels 2 are rotatably installed around the bottom of the support bottom plate 1. A side opening 3 is provided in the middle of the front end of the support bottom plate 1. A counterweight 4 is arranged on the side of the top of the support bottom plate 1. A push handle 5 is arranged on the side of the support bottom plate 1. A sampling lifting assembly 6 for sampling drive is arranged on the support bottom plate 1, and a quick sampling assembly 7 for sampling is arranged at the bottom of the sampling lifting assembly 6.

[0029] The sampling lifting assembly 6 includes a lifting connection bin 601 arranged at the top of the support bottom plate 1. A sampling drive motor 602 is arranged in the lifting connection bin 601. Two side wall limit plates 603 are symmetrically arranged on both sides of the sampling drive motor 602. Two limit sliding grooves 604 are symmetrically opened on both sides of the inner wall of the lifting connection bin 601. The side wall limit plates 603 are slidably inserted into the limit sliding grooves 604. A lifting connection block 605 is arranged at the rear side of the sampling drive motor 602. A lifting screw rod 606 is vertically arranged in the lifting connection bin 601. The top end of the lifting screw rod 606 rotatably penetrates the top of the lifting connection bin 601, and the bottom end of the lifting screw rod 606 threadedly penetrates the lifting connection block 605. A lifting motor 607 is arranged at the top of the lifting connection bin 601, and the drive shaft of the lifting motor 607 is fixedly connected to the top end of the lifting screw rod 606.

[0030] The quick sampling assembly 7 includes a sampling connection cylinder 701 arranged at the bottom of the sampling drive motor 602. The top end of the sampling connection cylinder 701 is open and the inner wall is provided with connecting internal threads. A connecting external thread is arranged on the drive shaft at the bottom of the sampling drive motor 602. The sampling connection cylinder 701 is connected to the drive shaft of the sampling drive motor 602 by threads. A bottom connecting screw rod 702 is arranged at the bottom of the sampling connection cylinder 701. A hollow sampling cylinder 703 is arranged below the sampling connection cylinder 701, and the bottom of the hollow sampling cylinder 703 is open.

[0031] A top connecting screw ring 704 is arranged at the top end of the hollow sampling cylinder 703. The bottom connecting screw rod 702 is threadedly inserted into the top connecting screw ring 704. A sampling inlet 705 is opened on the side wall of the hollow sampling cylinder 703. A sampling drill bit 706 is arranged at the bottom of the hollow sampling cylinder 703. A fastening thread 707 is arranged on the outer side of the top end of the sampling drill bit 706. The bottom end of the sampling inlet 705 is open, and the inner wall of the bottom end of the sampling inlet 705 is provided with fixed internal threads.

[0032] Example 2: The difference between this example and Example 1 is that, among them, the side and bottom of the lifting connection bin 601 are both open.

[0033] It makes it clearer for users to observe the up and down movement of the sampling drive motor 602 in the lifting connection bin 601.

[0034] Embodiment 3: The difference between this embodiment and Embodiment 1 is that a blocking plate for anti - detachment is provided at the bottom end of the lifting screw rod 606.

[0035] When the lifting screw rod 606 drives the lifting connection block 605, it can prevent the lifting connection block 605 from detaching from the lifting screw rod 606.

[0036] Embodiment 4: The difference between this embodiment and Embodiment 1 is that between the sampling drill bit 706 and the hollow sampling cylinder 703, a fastening thread 707 is provided and thread - inserted at the bottom of the hollow sampling cylinder 703.

[0037] The connection between the sampling drill bit 706 and the hollow sampling cylinder 703 becomes more convenient, and it is convenient to open the bottom of the sample inlet 705.

[0038] In this embodiment, before the existing soil contaminated with petroleum hydrocarbons is repaired, a sampling device needs to be used for positioning and soil sampling. However, common soil sampling devices are large in volume and not easy to move. At the same time, it is difficult to completely remove the soil in the soil sampling bin, which will cause some contaminated soil to remain in the soil sampling bin, thus affecting the next sampling research and inspection and being inconvenient for users.

[0039] In summary, during specific implementation, when a user needs to sample the soil in a petroleum - hydrocarbon - contaminated area, since the overall volume of this device is small, it is more convenient for the user to push and transfer the device. Moreover, the device is also provided with a GIS sensor for accurately positioning the layout point before sampling by the user, making the sampling position more accurate.

[0040] After accurate positioning, the sampling lifting assembly 6 on the upper part of the support base plate 1 is pushed to the designated sampling point. The user starts the lifting motor 607, and the lifting motor 607 drives the lifting screw rod 606 to rotate. The lifting screw rod 606 thread - penetrates the lifting connection block 605, and then can drive the sampling drive motor 602 connected to its side to move up and down through the lifting connection block 605. Instead of in the traditional sampling process, where effective sampling of contaminated soil can only be achieved by manual pressing or large - scale excavation, under the drive of the sampling drive motor 602, the sampling of contaminated soil can be more accurate, avoiding secondary damage and pollution to the existing area caused by large - scale excavation.

[0041] The bottom side of the output shaft of the sampling drive motor 602 is connected to the sampling connection cylinder 701 through threads. When the user needs to sample contaminated soil at different contamination depths, the user can connect multiple sampling connection cylinders 701, thereby increasing the overall sampling depth, so as to facilitate the user to quickly sample the contaminated soil at any depth layer. The top end of the sampling connection cylinder 701 is inserted into the top connection screw ring 704 through the bottom connection screw 702 provided and is threadedly connected. The sampling drill bit 706 is threadedly inserted into the bottom of the sample inlet 705 through the fastening thread 707 provided on the outside and is threadedly connected thereto. At the same time, it can block and close the bottom of the sample inlet 705. Then, by starting the sampling drive motor 602, the sampling drill bit 706 can be driven to drill and sample the soil.

[0042] Thus, the soil to be sampled during the drilling process can enter the sample inlet 705 for storage. After pulling the quick sampling assembly 7 out of the ground, the user rotates the sampling drill bit 706, so that the sampling drill bit 706 is removed from the bottom of the sample inlet 705, and the bottom of the sample inlet 705 is in an open state. By knocking on the sample inlet 705, the user can quickly and conveniently clear the sampled soil in the sample inlet 705 completely, thus avoiding the sampled soil remaining in the sample inlet 705 and affecting subsequent continuous sampling use, and facilitating the user's next research and inspection sampling.
