[0002] Soil pollution remediation technology refers to the use of chemical, physical and biological technologies and methods to reduce the concentration of pollutants in the soil, fix soil pollutants, convert soil pollutants into low-toxic or non-toxic substances, and block the transfer pathways of soil pollutants in the ecosystem. Some remediation technologies, such as the remediation of degradable organic pollutants and heavy metal-contaminated soil, have entered the field application stage and achieved good results. It is of great significance to implement remediation of contaminated soil to block pollutants from entering the food chain, prevent harm to human health, and promote land resource protection and sustainable development.

[0003] In the prior art, when testing contaminated soil after restoration, sampling is usually performed in the soil according to a time period before testing. Although this testing method has high accuracy in testing the long-term effectiveness of the restoration agent, its time span is relatively long. Testing the soil restoration agent through a simulated environment can perform long-term simulated testing in a short period of time. The existing simulation testing device directly tests by simulating acid rain after the soil is loaded. It is also necessary to use a separate sampler to repeatedly sample the soil before testing. The steps are cumbersome. Although the span of the detection time is shortened, the detection operation is not convenient enough, which affects the efficiency of soil testing.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Embodiment 1:

[0032] See also Figure 1-6 The present invention provides a long-term detection device for heavy metal contaminated soil remediation agents, comprising:

[0033] Device box 1 and detection platform 21;

[0034] The lifting bracket 10 is arranged in the device box 1. The upper surface of the lifting bracket 10 is provided with a plurality of card slots 16. A card head 15 with a hollow interior is slidably connected in the plurality of card slots 16. The bottom end of the card head 15 is connected to a rotatable sampling tube head 11 through a bearing. A piston push block 13 is slidably connected in the card head 15. The top end of the piston push block 13 is fixedly connected to a push rod 12.

[0036] The limiting top plate 4 is fixedly connected to the outer wall of the device box 1, and the limiting top plate 4 is located directly above the lifting bracket 10. A material receiving trough box 18 for receiving materials is slidably engaged in the detection platform 21;

[0037] The guide screw 7 is arranged in the device box 1. A threaded block 17 is fixedly connected to one side of the lifting bracket 10, and the threaded block 17 and the guide screw 7 are threadedly connected. The guide screw 7 is connected to the device box 1 through a driving mechanism.

[0038] Specifically, Figure 3 and Figure 4 As shown, the outer wall of the clamping head 15 has convex blocks on both sides, and the limit block 14 is designed as an "L"-shaped structure. The two limit blocks 14 in a group are symmetrically distributed along the central axis of the clamping head 15, and the ends of the two limit blocks 14 in a group are opposite to each other. When the clamping head 15 is rotated 90 degrees, the convex blocks at both ends are respectively connected to the two limit blocks 14 in a group. The shape structure of the clamping head 15 is consistent with the shape structure of the card slot 16. Through its design, when the lifting bracket 10 rises, when the clamping head 15 is rotated until its two ends are connected to the corresponding limit blocks 14, the clamping head 15 can maintain contact with the lifting bracket 10. The lifting bracket 10 is connected so that the lifting bracket 10 can drive the corresponding sampling tube head 11 to rise, and the non-rotating clamping head 15 corresponds to the clamping slot 16, so that when the lifting bracket 10 rises, the clamping head 15 that is not connected to the limit block 14 directly passes through the clamping slot 16, so that the lifting bracket 10 can drive a single sampling tube head 11 for sampling in turn, and at the same time it is convenient to drive each sampling tube head 11 to rise together, so that after the long-term detection of soil remediation is completed, the sampling tube head 11 can be directly lifted up together for cleaning, and it is easy to use.

The caliber of the sampling tube head 11 is equal to the caliber of the clamp 15. Through its design, when the push rod 12 rises with the clamp 15, its top end abuts against the limit top plate 4, which can increase the contact surface between them, making it easier for the push rod 12 to stably bear the force and squeeze out the soil in the sampling tube head 11 through the piston push block 13, which provides convenience for rapid soil sampling.

When it is necessary to drive the lifting bracket 10 to lift, the servo motor 9 drives the main gear 6 to rotate, so that the main gear 6 meshes with the transmission slave gear 8 to rotate, so that the slave gear 8 drives the guide screw 7 to rotate, and the lifting bracket 10 is threadedly connected to the guide screw 7 and is forced to rise. The lifting bracket 10 can be driven to descend by rotating the guide screw 7 in the direction of operation.

[0042] Specifically, Figure 1 As shown, two guide grooves 24 are provided on one side of the inner wall of the device box 1, and sliders 23 are fixedly connected to both sides of one side of the lifting bracket 10, and one end of the slider 23 is slidably engaged in the guide groove 24 at the corresponding position. By arranging the slider 23 on one side of the lifting bracket 10, it can be slidably connected and cooperated with the guide groove 24, so that the lifting bracket 10 can be limited to ensure that the lifting bracket 10 is not offset when the guide screw 7 rotates, which provides a good guarantee for the normal lifting of the lifting bracket 10.

[0043] Specifically, Figure 2 As shown, a limiting pull plate 19 is fixedly connected to the bottom of one end of the material receiving trough box 18, a guide groove 20 is provided at the bottom of the detection platform 21, and the limiting pull plate 19 is slidably engaged with the guide groove 20.
