Soil pollution not only affects the growth and quality of crops, but can also be transmitted to humans through the food chain, posing a potential threat to human health. Therefore, it is particularly important to control and monitor soil pollution. Currently, there are many types of environmental monitoring devices used for soil pollution control, but some problems still exist in practical applications. Traditional monitoring devices are often only able to adapt to specific terrain and soil conditions and have poor adaptability to complex terrain. For example, in areas with complex terrain such as mountainous areas and wetlands, it is difficult for traditional monitoring devices to find a stable landing point and installation location, resulting in inaccurate monitoring data or the inability to conduct monitoring.

[0041] The horizontal extension mechanism 3 includes a first rectangular sleeve 301, which is slidably connected to the triangular support plate 1. The inner wall of the first rectangular sleeve 301 is fixedly connected to a first spring 302, the right end of the first spring 302 is fixedly connected to a second rectangular sleeve 303, the inner wall of the second rectangular sleeve 303 is fixedly connected to a second spring 304, the right end of the second spring 304 is fixedly connected to a first rectangular column 305, and the right end of the first rectangular column 305 is provided with a first slot 306.

[0042] The horizontal extension mechanism 3 also includes a first threaded pin 308. The triangular support plate 1, the first rectangular sleeve 301, the second rectangular sleeve 303 and the first rectangular column 305 are all provided with a first threaded through hole 307. The triangular support plate 1, the first rectangular sleeve 301 and the second rectangular sleeve 303 are threadedly connected through the first threaded pin 308. The second rectangular sleeve 303 and the first rectangular column 305 are threadedly connected through the first threaded through hole 307 with a second threaded pin 309.

[0043] The horizontal extension mechanism 3 is symmetrically arranged with three groups on the outer surface of the screw 7. The first rectangular column 305 is clamped with the second rectangular sleeve 303, and the second rectangular sleeve 303 is clamped with the first rectangular sleeve 301. By setting the horizontal extension mechanism 3, the first rectangular sleeve 301, the first spring 302, the second rectangular sleeve 303, the second spring 304, the first threaded nail 308 and the second threaded nail 309 can be used to improve the device for different terrain and soil conditions, adjust the extension length and direction of the rod, better adapt to different soil and terrain conditions, improve the accuracy and reliability of data collection, and provide more powerful support for soil pollution control.

[0044] The vertical extension mechanism 6 includes an annular column 601, which is clamped with the first slot 306. The inner surface of the annular column 601 is fixedly connected to the first circular sleeve 602, and the interior of the first circular sleeve 602 is rotatably connected to the first turntable 603. The top of the first circular sleeve 602 is provided with a rectangular slot 604, and the interior of the rectangular slot 604 is clamped with a rotating rod handle 605.

The top of the triangular column 607 is fixedly connected to a threaded drill bit 608. The interior of the first circular sleeve 602 and the triangular column 607 are both provided with a second threaded through hole 609, and the interior of the second threaded through hole 609 is threadedly connected to a third threaded nail 610.

[0045] The lower surface of the rotating rod handle 605 contacts the upper surface of the first rotating disk 603, the triangular column 607 is clamped with the first circular sleeve 602, and the first circular sleeve 602 and the triangular column 607 are threadedly connected by the third threaded nail 610. By setting the vertical extension mechanism 6, not only can the adaptability of the environmental monitoring device to different terrains be further enhanced through the triangular column 607 and the first circular sleeve 602, but the horizontal state of the monitoring device can also be achieved through independent control through the symmetrically arranged vertical extension mechanism 6, providing more accurate and reliable data support for soil pollution control.

[0046] The working principle of this embodiment is as follows: when the environmental monitoring device for soil pollution control is used and the device needs to be adjusted, the first threaded pin 308 and the second threaded pin 309 are moved out by threaded rotation, and the first spring 302 pushes the second rectangular sleeve 303 to move outward along the inner surface of the first rectangular sleeve 301, and the second spring 304 pushes the first rectangular column 305 to move outward on the inner surface of the second rectangular sleeve 303. When the threaded drill bit 608 is moved outward to a certain position, the first threaded pin 308 is threaded in to fix the triangular support plate 1, the first rectangular sleeve 301 and the second rectangular sleeve 303, and the second threaded pin 309 is threaded in to fix the second rectangular sleeve 303 and the first rectangular column 305. If the moving distance is insufficient, the first rectangular sleeve 301 is pulled to move in the slot of the triangular support plate 1 and fixed by the first threaded pin 308 to increase the distance, and the horizontal distance is increased and fixed with the symmetrically arranged horizontal extension mechanism 3. , by rotating the rotating rod handle 605, the first circular sleeve 602 is driven to rotate, and the annular column 601 is driven to rotate inside the first slot 306. At this time, the first circular sleeve 602 drives the triangular column 607 to rotate, and drives the threaded drill bit 608 to rotate and enter the soil for vertical fixation. At this time, by lifting the entire device upward, the first circular sleeve 602 and the triangular column 607 are screwed and fixed from the second threaded through hole 609 to achieve height fixation, and the first rotating disk 603 ensures that the third spring 606 does not bear the rotation of the first circular sleeve 602 when rotating, and the third spring 606 and the first rotating disk 603 achieve the fixation of the triangular column 607 and the first circular sleeve 602. Then, the device is leveled through the symmetrically arranged vertical extension mechanism 6. At this time, the sliding support rod 2 slides inside the through hole of the triangular support plate 1, so that the collecting device 8 contacts the ground. The motor 5 starts to rotate, driving the screw 7 to rotate, and the screw 7 drives the collecting device 8 to rotate into the soil for monitoring.

[0047] Example 2: Please refer to Figure 7-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary support mechanism 9 includes an auxiliary component 9001, the auxiliary component 9001 includes a threaded sleeve 901 threadedly connected to the first threaded nail 308, the interior of the threaded sleeve 901 is rotatably connected to the second turntable 902, the bottom of the second turntable 902 is fixedly connected to the shaft connecting block 903, the outer surface of the shaft of the shaft connecting block 903 is rotatably connected to the first connecting rod 904, the bottom of the first connecting rod 904 is fixedly connected to a T-shaped column 905, the interior of the T-shaped column 905 is fixedly connected to an electromagnet 906, the interior of the T-shaped column 905 is slidably connected to a friction chuck 907 and a second connecting rod 908, and the outer surface of the T-shaped column 905 is fixedly connected to a fourth spring 909.

[0048] Two groups of auxiliary components 9001 are symmetrically arranged on the outer surface of the T-shaped column 905, and are threadedly connected to the first threaded nail 308 and the second threaded nail 309. The right end of the second connecting rod 908 is fixedly connected to the auxiliary component 9001 and is threadedly connected to the third threaded nail 610. The outer surface of the friction chuck 907 is in contact with the outer surface of the second connecting rod 908. By setting up an auxiliary support mechanism 9, the first connecting rod 904 and the second connecting rod 908 can provide effective auxiliary support for the horizontal extension mechanism 3 and the vertical extension mechanism 6, thereby enhancing the stability and adaptability of the environmental monitoring device for soil pollution control under different terrain conditions; through the fourth spring 909, the friction chuck 907 and the electromagnet 906, it can be adjusted according to different terrains and needs, ensuring that the monitoring device can accurately measure soil parameters and provide reliable data support for soil pollution control.

[0049] Through the coordinated action of the horizontal extension mechanism 3, the vertical extension mechanism 6 and the auxiliary support mechanism 9, the environmental monitoring device for soil pollution control achieves important functions such as adapting to various terrains, ensuring monitoring accuracy, improving device stability and enhancing operability, providing strong technical support for soil pollution control, and achieving energy conservation by setting up fewer power components.

[0050] The working principle of this embodiment is as follows: when using this environmental monitoring device for soil pollution control, during monitoring, the threaded sleeve 901 is threadedly connected and fixed to the outer surface of the first threaded nail 308, and the symmetrically arranged threaded sleeve 901 realizes the threaded connection and fixation of the second threaded nail 309 and the third threaded nail 610. When the first threaded nail 308 and the second threaded nail 309 are fixed, the first connecting rod 904 rotates around the outer surface of the rotating shaft of the rotating shaft connecting block 903, and cooperates with the symmetrically arranged first connecting rod 904 to support and fix it, while the third threaded nail 308 and the second threaded nail 309 are fixed. When the pattern pin 610 is fixed, it rotates around the set rotating shaft connecting block 903, and at this time drives the second connecting rod 908 to slide inside the T-shaped column 905, and the fourth spring 909 pushes the T-shaped column 905 to move, so that its position is stable. At this time, the electromagnet 906 starts to push the friction chuck 907 to make close contact with the outer surface of the second connecting rod 908, and the second turntable 902 is rotated by the threaded sleeve 901 without affecting the rotating shaft connecting block 903, and the position is fixed, thereby realizing auxiliary support for the horizontal extension mechanism 3 and the vertical extension mechanism 6.
