Description

Technical Field

[0001] This utility model belongs to the field of soil testing equipment, and in particular relates to a soil moisture testing device for ecological restoration. Background Technology

[0002] Mine ecological restoration refers to the comprehensive management of areas ecologically damaged by mining activities to restore their ecological functions, improve environmental quality, and achieve sustainable utilization. Mining activities often lead to a series of ecological problems such as soil erosion, vegetation destruction, water pollution, and biodiversity loss. To achieve vegetation restoration, native plant species suitable for mining areas are selected for planting and restoration to increase vegetation cover. Vegetation restoration not only conserves water and soil and purifies the air, but also provides habitats for animals and promotes biodiversity recovery. The core of soil moisture monitoring is obtaining key parameters of soil moisture, which can serve as a reference for vegetation restoration.

[0003] Existing patent CN202220682527.7 discloses a wireless soil moisture meter for monitoring soil moisture. It uses a threaded connection between a screw and a connecting block. Rotating a rotating ring drives the screw to rotate, causing the connecting block to move along the screw thread. This allows the connecting block to move the connecting sleeve and the soil moisture meter vertically, adjusting the depth of the probe insertion into the soil for convenient monitoring at different depths. However, mining areas differ from other monitoring environments. Many mines have surfaces covered with a layer of ore and sand, affecting the installation and data collection of the soil moisture meter. Furthermore, outdoor soil moisture meters often require a fixed installation period to obtain sufficient and reliable data, during which a power supply must be guaranteed; otherwise, the collected data cannot be wirelessly transmitted to the receiving end.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Examples, such as Figures 1-3As shown, the soil moisture monitoring device for ecological restoration provided by this utility model includes a mounting frame 1. The mounting frame 1 includes a base plate 11 and a mounting cylinder 12 mounted on the base plate 11. A ground bolt 13 is provided on the base plate 11. A soil moisture meter 2 is provided on the mounting cylinder 12. At least one probe assembly 3 connected to the soil moisture meter 2 is provided inside the mounting cylinder 12. A photovoltaic support rod 4 is provided on the mounting frame 1. A photovoltaic module 5 is provided on the photovoltaic support rod 4. The photovoltaic module 5 includes a photovoltaic panel, an inverter, and a battery. The inverter is located at the bottom of the photovoltaic panel. The battery is located inside the mounting cylinder 12 and connected to the inverter via wires; the battery is connected to the soil moisture meter 2. The side of the mounting cylinder 12 is provided with multiple strip holes 14. The side of the probe assembly 3 is provided with a slider 31 that mates with the strip holes 14. An adjusting cylinder 6 is provided on the outside of the mounting cylinder 12. Multiple connecting screws 61 connecting the adjusting cylinder 6 and the slider are provided on the adjusting cylinder 6. Three evenly distributed connecting rings 7 are provided near the top of the mounting cylinder 12. Connecting ropes 8 are provided on the connecting rings 7. A ground gripping part 9 is provided at the end of the connecting ropes 8.

[0020] Specifically, the photovoltaic panel frame of the photovoltaic module 5 can be connected to the photovoltaic support rod 4 by screws or by welding. The photovoltaic module 5 converts solar energy into electrical energy through the photovoltaic panel. The electrical energy is stored in the battery through an inverter, and the battery provides power to the soil moisture meter 2, ensuring that the soil moisture meter 2 can effectively transmit detection data during long-term outdoor operation. Regarding the probe assembly 3, the probe assembly 3 includes a probe body and a connecting cable. The connecting cable is plugged into the soil moisture meter 2, and the actual detection depth of the probe body can be adjusted by changing the vertical position of the adjusting cylinder 6 on the mounting cylinder 12 to meet the needs of on-site soil moisture detection.

[0021] To improve the reliability of this device's installation outdoors, especially on mine surfaces, this invention, in addition to providing a ground anchor 13 to secure the base plate 11 to the detection point, also includes a ground gripping component 9. The ground gripping component 9 extends a connecting rope 8 from the connecting ring 7, acting as a lever arm, while the gripping component 9 is directly buried under the mine's sand and gravel. This provides multiple supporting lever arms for the mounting frame 1, effectively providing a highly stable support system and ensuring the installation stability of the device, thus facilitating the acquisition of effective detection data. Therefore, this device offers stable installation conditions on mine surfaces, possesses photovoltaic power generation capabilities, and facilitates data transmission, meeting the requirements for on-site soil moisture detection.

[0022] To improve the gripping performance of the gripping component 9 on the mine surface, the gripping component 9 provided by this utility model includes a U-shaped frame 91, which is buried under the sand and gravel on the mine surface. An elastic plate 92, with a different side from the U-shaped frame 91, is provided on the inner side of the U-shaped frame 91. In this way, the sand and gravel on the mine surface act as a pressure device on the U-shaped frame 91, providing contact lines with the sand and gravel. The specific length and width dimensions of the U-shaped frame 91 can be designed to be slightly larger, especially to accommodate different types of sand and gravel present on site. Combined with the downward gripping force of the elastic plate 92, the connecting rope 8 has corresponding anti-derailment performance under wind force, which helps improve the overall stability of the device in the outdoor environment of the mine.

[0023] Furthermore, the cross-section of the elastic plate 92 provided by this utility model is M-shaped, and the end of the M-shape is a sharp blade, which allows the end of the elastic plate 92 to have a certain holding force with the ground in its opposite action range; the elastic plate 92 has a certain elasticity, which allows the elastic plate 92 to deform accordingly under the action of external force, and at the same time obtain the tendency to recover the deformation, so that the flexible lever arm formed by multiple connecting ropes 8 and gripping parts 9 can maintain dynamic balance within a certain range, which is beneficial to improving the stability of this device after installation and positioning.

[0024] To ensure that the adjusting cylinder 6 has a certain vertical adjustment range, this utility model provides a strip hole 14. The upper and lower ends of the strip hole 14 are used as the upper and lower stops of the slider 31. When the adjusting cylinder 6 is at the upper stop, multiple insertion ports 62 corresponding to the connecting ring 7 are provided near the top of the adjusting cylinder 6. The top of the insertion port 62 passes through the top of the adjusting cylinder 6, which can provide a reasonable upward path for the adjusting cylinder 6 and improve the actual combination performance of the adjusting cylinder 6 and the mounting cylinder 12.

[0025] To improve the stability of the probe assembly 3 at the detection site, this invention utilizes an adjusting cylinder 6 as the vertical adjustment structure for the probe assembly 3. The adjusting cylinder 6 has multiple positioning screws 63 spaced apart from the insertion port 62 near its top. The mounting cylinder 12 has a slotted groove 15 that mates with the positioning screws 63. By tightening the positioning screws 63, the ends of the screws 63 abut against the slotted groove 15, clamping the mounting cylinder 12 and preventing free sliding between the adjusting cylinder 6 and the mounting cylinder 12, thus ensuring the working performance of the probe assembly 3.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
