How to effectively carry out soil and water loss soil erosion monitoring and restoration has become a focus of widespread concern at home and abroad. In the 18th century, European soil scientists established runoff observation plots, pioneering the history of quantitative monitoring of soil erosion. Conventional soil erosion monitoring methods mainly include survey method, runoff plot method, erosion probe (needle) method, hydrological method and remote sensing interpretation method. Runoff plot observation and erosion probe (needle) method are commonly used methods in ground observation methods for soil and water conservation monitoring. In this method, soil erosion is measured by laying soil measuring rods. It has been widely used in soil and water conservation monitoring. The erosion probe method is suitable for field observation, easy to operate and low cost. It is one of the soil erosion measurement methods in the standards promulgated by my country's soil and water conservation.

[0003] However, the disadvantages of traditional erosion drills are that the solid steel drill is too heavy and not easy to carry, and its verticality cannot be guaranteed during manual installation. Secondly, the drill measurement usually uses traditional measuring tools, and the drill cannot directly read the depth of soil burial, which is easy to cause human interference to the drill. In addition, the drill is easily affected by climatic conditions such as rainfall, surface runoff, wind, and human interference during long-term observation and use in the field, causing the drill to tilt or fall. Therefore, the traditional drill has defects such as insufficient measurement accuracy, uncontrollable verticality, and easy tilt or fall during use, making it difficult to achieve efficient and high-precision collection of soil erosion data.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Reference Figure 1-5The embodiment provides a soil erosion measuring device for preventing tilting. The device can check the horizontal state of the entire device by folding the leveling handle 4 to prevent the device from tilting. The measuring device can be fixed by the anti-tilting check assembly 6, thereby avoiding the problem of the measuring device tipping over due to rainfall, surface runoff, wind and human influence after the measuring device is placed, thereby extending the service life of the device. The soil erosion measuring device for preventing tilting comprises a drill head 1, a drill rod 2, a fixing rod 3 and a folding leveling handle 4. The fixing rod 3 is fixedly sleeved with the drill rod 2. The top surfaces of the drill rod 2 and the fixing rod 3 are provided with a drill cap 5. The bottom surface is fixedly connected to the drill head 1. The drill head 1 It is set as a cone, and an anti-tilt check component 6 is movably sleeved on the lower part of the fixed rod 3. An anti-tilt check groove 7 for the anti-tilt check component 6 to be retracted is provided at the lower part of the drill rod 2. An adjustable and fixed ruler component 8 is provided on the outer part of the drill rod 2. The ruler component 8 can be flexibly adjusted according to the on-site conditions. An L-shaped slot 30 for connecting the folding leveling handle 4 is provided on the upper part of the drill rod 2. The folding leveling handle 4 can be pressed down in the longitudinal slot of the L-shaped slot 30 to open the anti-tilt check component 6, so that the device is not easy to tip over. The position of the anti-tilt check component 6 can be locked by rotating it in the transverse slot, so that the anti-tilt check component 6 always remains in a stretched state.

[0026] Furthermore, a support rod 9 is movably arranged between the fixed rod 3 and the drill rod 2. The length of the support rod 9 is shorter than that of the fixed rod 3, which makes it more convenient to slide on the fixed rod 3. The lower end of the support rod 9 is connected to the anti-tilt check component 6. The support rod 9 slides toward the bottom to open the anti-tilt check component 6 so that it extends out of the drill rod 2 and inserts into the soil, so that the device will not tip over.

[0027] Specifically, the anti-tilt check component 6 includes an upper connection nest 10, a lower connection nest 11 and an anti-tilt check wing 12. A circle of limiting grooves 13 are provided at the lower end of the support rod 9. The upper connection nest 10 is movably sleeved on the limiting groove 13. The lower connection nest 11 is fixedly sleeved on the lower end of the fixed rod 3. The upper connection nest 10 and the anti-tilt check wing 12 are movably connected through a connecting rod 14. The root of the anti-tilt check wing 12 is movably connected to the lower connection nest 11. A handle connection port 15 for connecting a folding leveling handle 4 is provided on the upper part of the support rod 9. The folding leveling handle 4 passes through the L-shaped slot 30 to connect to the handle connection port 15. After the device reaches the predetermined depth, the folding leveling handle 4 is pressed down in the longitudinal groove of the L-shaped slot 30 to make the support rod 9 slide downward, driving the upper connecting nest 10 to move downward, unfolding the anti-tilt check wing 12 from the anti-tilt check groove 7 and inserting it into the soil. When the folding leveling handle 4 is pressed down to the transverse groove of the L-shaped slot 30, it is rotated to fix the support rod 9. The upper connecting nest 10 is not easily lifted, and the anti-tilt check wing 12 is better fixed in the soil. Because the upper connecting nest 10 is movably mounted on the limit groove 13, the upper connecting nest 10 will not rotate with the support rod 9.

[0028] The number of the anti-tilt and non-return wings 12 matches the number of the anti-tilt and non-return grooves 7 .

[0029] Furthermore, a spring 16 is provided between the lower connection nest 11 and the support rod 9. The spring 16 is sleeved on the fixing rod 3. The spring 16 can ensure that the anti-tilt check wing 12 is in a retracted state when the support rod 9 is not in a downwardly pressed state.

[0030] Specifically, the folding level handle 4 includes a shell 17, a level bubble 18 and a folding screw 19. The level bubble 18 is horizontally embedded in the top surface of the shell 17. One end of the folding screw 19 is rotatably connected to the inner wall of the shell 17, and the other end extends out of the shell 17 to pass through the L-shaped slot 30 and spirally connect to the handle connecting port 15.

[0031] Furthermore, the folding leveling handle 4 also includes a locking bolt 20 and a spring sheet 21. The middle part of the locking bolt 20 is rotatably connected to the inner wall of the shell 17, one end of the spring sheet 21 is fixedly connected to the inner wall of the shell 17 away from the folding screw 19, and the other end of the spring sheet 21 resists and fixes the locking bolt 20. A notch 22 is provided at one end of the folding screw 19 to clamp one end of the locking bolt 20. The end of the locking bolt 20 away from the notch 22 extends out of the shell 17 for easy pressing down to unlock. By pressing one end of the locking bolt 20 to lift the other end of the locking bolt 20 stuck in the notch 22, the folding leveling handle 4 can be rotated around the folding screw 19 for folding and storage. Stop pressing the locking bolt 20, and the locking bolt 20 is clamped into the notch 22 under the pressure of the spring sheet 21.

[0032] Specifically, the scale assembly 8 includes a marking line clamp 23, an upper arc scale 24, a lower arc scale 25 and a positioning screw 26. The marking line clamp 23 is sleeved on the outer wall of the drill rod 2, the lower end of the lower arc scale 25 is set to a triangle, directly contacting the soil surface, the upper end of the lower arc scale 25 is fixedly connected to the upper arc scale 24, the lower end of the upper arc scale 24 is provided with a 0 scale line, and the lower end of the lower arc scale 25 is provided with a 0 scale line. One side of the marking line clamp 23 is provided with an arc groove 27 for the upper arc scale 24 to slide and the size of the upper arc scale 24 matches. One end of the positioning screw 26 passes through the marking line clamp 23 and presses against the drill rod 2 to fix the marking line clamp 23, so that the lower end of the lower arc scale 25 contacts the soil, and then the marking line clamp is adjusted to the 0 scale line position of the upper arc scale 24 by the positioning screw 26.

[0033] Among them, the size of the lower arc scale 25 is larger than the upper arc scale 24. The upper arc scale 24 records the amount of soil erosion, and the lower arc scale 25 records the amount of soil deposition. When soil loss or other erosion conditions occur, the lower arc scale 25 will drive the upper arc scale 24 to fall. At this time, the soil erosion amount is recorded by directly reading the reading of the upper arc scale 24 corresponding to the horizontal standard line clamp 23. When soil deposition occurs during the monitoring process, the soil deposition amount is recorded by reading the reading of the lower arc scale 25, which improves the practicability of the device under different soil thicknesses and complex terrain conditions.

[0034] Preferably, the upper end of the upper arc-shaped scale 24 is fixedly connected to a movable slip ring 28 , which is slidably sleeved on the outer wall of the drill rod 2 , and a sliding ball 29 is arranged on the inner wall of the movable slip ring 28 , which can slide up and down on the drill rod 2 .

[0035] The method of using the anti-tilt soil erosion measuring device is as follows:

[0036] Step 1: According to the thickness of the soil layer at the monitoring point, adjust the positioning screw 26 of the marking line clamp 23, fix the adjustable scale assembly 8 to the upper part of the drill rod 2, and reserve the buried length at the lower part of the drill rod 2;

[0037] Step 2: Open the foldable level handle 4, adjust the level bubble 18 to the center, and press or knock the drill cap 5 so that the drill rod 2 moves downward under the pressure, so that the drill rod 2 vertically enters the soil layer;

[0038] Step 3: After the device reaches the predetermined depth, press the folding level handle 4 downward, so that the support rod 9 drives the upper connecting nest 10 and the connecting rod 14 to open the anti-tilt check wing 12, and rotate the folding level handle 4 to the L-shaped slot to fix the support rod 9. During the downward pressing process, the device is continuously adjusted by observing the level bubble 18 so that the level bubble 18 always remains in a horizontal state. After the support rod 9 is fixed, the device can always remain vertical and reach a relatively stable state.

[0039] Step 4: Open the positioning screw 26 and move the slip ring 28 to drive the upper arc scale 24 and the lower arc scale 25 to descend until the lower end of the lower arc scale 25 contacts the soil.

[0040] Step 5: Adjust the marking line clamp 23 to the 0 scale line of the upper arc scale 24, tighten the positioning screw 26, and fix it to the drill rod 2;

[0041] Step 6: Press the lock bolt 20 on the foldable leveling handle 4, rotate and retract the foldable leveling handle 4, and complete the setting;

[0042] Step 7: When soil erosion occurs during the monitoring process, the lower end of the lower arc scale 25 contacts the ground, and as the soil is lost, the lower arc scale 25 drops, and the soil erosion amount is recorded by directly reading the reading of the upper arc scale 24 corresponding to the horizontal standard line clamp 23; when soil deposition occurs during the monitoring process, the soil deposition amount is recorded by reading the reading of the lower arc scale 25;

[0043] Step 8: When the observation is finished, open the foldable leveling handle 4, pull it upward after rotating the L-shaped slot 30, retract the anti-tilt and non-return wings 12, and lift the device out of the ground, and the use is finished.

[0044] The parts not specifically described in the above description are all prior art, or can be implemented by prior art. Moreover, the specific implementation cases described in this utility model are only preferred implementation cases of this utility model, and are not used to limit the implementation scope of this utility model.
