Description

Technical Field

[0001] The present invention relates to the technical field of soil monitoring, and in particular to a soil loss monitoring device and a soil loss monitoring method. Background Art

[0002] Soil resources are natural resources that humans rely on for survival. However, the problem of soil loss is becoming increasingly serious due to natural and human factors. On the one hand, under extreme weather events such as rainstorms and floods, water cannot be absorbed locally and will flow down along the terrain, eroding the soil, causing serious soil loss. In addition, the complex terrain, large slopes, and fast water flow in mountainous areas are also prone to soil erosion. In plain areas, the erosion and sedimentation of rivers will also have a certain impact on the soil. On the other hand, with the acceleration of urbanization and the continuous advancement of infrastructure construction, a large amount of land has been developed and disturbed. During the construction process, activities such as excavation and filling will destroy the original structure and stability of the soil and increase the risk of soil loss. At the same time, unreasonable land development and utilization, such as excessive reclamation and overgrazing, will also lead to the destruction of vegetation on the surface of the soil, making the soil unprotected and susceptible to erosion by water and wind, ultimately leading to soil loss.

[0003] In order to fully understand the status of soil loss and formulate effective control measures, people need to monitor the height of soil loss. Existing soil loss monitoring devices generally monitor the value of soil settlement by inserting a rod into the ground, leaving it for a period of time, and then manually reading the changes in the scale value on the rod. This type of soil loss monitoring device has large reading errors, low measurement accuracy, and poor reliability. Summary of the invention

[0018] In an optional embodiment, a level bubble meter is provided on the mounting base.

[0019] Beneficial Effects

[0020] By setting the level bubble meter, it can be determined whether the rod is inserted vertically, so as to ensure that the distance measuring device is lowered in the vertical direction, and to ensure that the measured height position data is more accurate.

At the same time, the scale marked on the plug rod also makes it easier for the staff to roughly judge the soil settlement condition at that location.

[0026] In a second aspect, the present invention further provides a soil loss monitoring method, which is applied to the soil loss monitoring device, comprising:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] Combine the following Figure 1 , Figure 2 Embodiments of the present invention are described.

[0056] According to an embodiment of the present invention, on the one hand, a soil loss monitoring device is provided. The soil loss monitoring device includes: an insertion rod 1, a mounting seat 2 and a monitoring component. The mounting seat 2 is arranged at one end of the insertion rod 1. The monitoring component includes: a distance measuring device 31, a lowering device 32 and a data reading device 33, the lowering device 32 is arranged on the mounting seat 2, and its driving end is connected to the distance measuring device 31, the lowering device 32 is used to retract and release the distance measuring device 31 in the vertical direction, the data reading device 33 is arranged on the mounting seat 2, and is communicatively connected with the lowering device 32, and the data reading device 33 is used to read the height position of the distance measuring device 31.

[0057] The main part of the insertion rod 1 is a round rod, one end of which is a pointed tip for easy insertion into the soil, and the other end is provided with a mounting seat 2. The mounting seat 2 is disc-shaped, and the connection between the mounting seat 2 and the insertion rod 1 is located at the center of the mounting seat 2. The lowering device 32 and the data reading device 33 are both arranged on the mounting seat 2. When the monitoring device is not in use, the lowering device 32 retracts the distance measuring device 31, and when the monitoring device is in use, the lowering device 32 lowers the distance measuring device 31 to the ground. The lowering device 32 can be provided with one, or multiple devices can be provided along the circumference of the mounting seat 2. The number of distance measuring devices 31 is equal to the lowering device 32, that is, each lowering device 32 is connected to a distance measuring device 31. The distance measuring device 31 is provided with a height measuring module, which can measure the height change of the distance measuring device 31, such as the initial height of the distance measuring device 31, the lowering height, and the height after soil settlement. When the distance measuring device 31 is lowered, the data reading device 33 can read the height position change of the distance measuring device 31 in real time. The height position of the distance measuring device 31 obtained by the data reading device 33 is more accurate and has a smaller error than that of manual readings. The measurement accuracy and reliability of the monitoring device are also higher.

[0058] In one embodiment, the two distance measuring devices 31 and the two lowering devices 32 are symmetrically arranged on both sides of the insertion rod 1 .

[0059] That is, two lowering devices 32 are arranged on the mounting seat 2, each lowering device 32 is connected to a distance measuring device 31, and the two lowering devices 32 and the two distance measuring devices 31 are symmetrically arranged on both sides of the insertion rod 1. In this way, the monitoring device can obtain two sets of height position change values ​​of the two distance measuring devices 31 each time it measures, and by taking the average value, it can obtain more accurate measurement results and reduce measurement errors. Moreover, when this soil loss monitoring device is used on a slope with a slope, the two distance measuring devices 31 can be placed one above and one below on the slope, so that the monitoring device can still maintain a high measurement accuracy.

[0060] In other embodiments, only one distance measuring device 31 and one lowering device 32 may be provided, or three distance measuring devices 31 and three lowering devices 32, four distance measuring devices 31 and four lowering devices 32, or a greater number of distance measuring devices 31 and lowering devices 32 may be provided.

[0061] In one embodiment, the lowering device 32 includes: a driving member 321 and a connecting rope 322 . The driving member 321 is disposed on the mounting seat 2 . One end of the connecting rope 322 is connected to the driving member 321 , and the other end is connected to the distance measuring device 31 .

[0062] Specifically, the driving member 321 is preferably a motor, and the motor output shaft rotates to retract and release the connecting rope 322, thereby retracting and releasing the distance measuring device 31. The data reading device 33 obtains the lowering height of the distance measuring device 31 by the number of rotations of the motor output shaft. The connecting rope 322 is a reelable flexible rope.

[0063] In other embodiments, the driving member 321 may be other types of rotary driving mechanisms, or may be a linear driving mechanism such as a cylinder.

[0064] In one embodiment, a display screen 4 is further provided on the mounting base 2 . The display screen 4 is communicatively connected with the data reading device 33 . The display screen 4 is used to display the height position of the distance measuring device 31 .

[0065] The display screen 4 is arranged on the top surface of the mounting base 2, so that the staff can read the information conveniently. The display screen 4 has a switch button to start or shut down the monitoring device. The display screen 4 also displays the height position of the distance measuring device 31 and the difference of the height position at different times in real time, which is the soil settlement value at the monitoring device at the current time and the initial time.

[0066] In one embodiment, a level bubble gauge 5 is provided on the mounting base 2 .

[0067] The bubble level meter 5 can determine whether the mounting base 2 is horizontal based on the principle that bubbles always tend to remain at the highest position in the liquid. When the mounting base 2 is tilted, the bubbles in the bubble level meter 5 will move accordingly. By observing the change in the position of the bubbles, the tilt direction and angle of the mounting base 2 can be determined. Correspondingly, it can also be determined whether the insertion rod 1 is vertically inserted into the ground and whether it is kept in a vertical state during use. Because when the insertion rod 1 and the mounting base 2 are tilted, the error of the measurement data will increase and the measurement accuracy will be reduced.

[0068] In one embodiment, the mounting seat 2 is rotatably disposed at one end of the insertion rod 1, that is, the mounting seat 2 can be rotated around its axis to any angle.

[0069] In one embodiment, the insertion rod 1 is marked with 6 scale lines.

[0070] In one embodiment, a laser 7 is disposed on the mounting base 2 .

[0071] When there are multiple soil loss monitoring devices, the positions of the multiple soil loss monitoring devices are calibrated one by one through the bubble level meter 5. Then the mounting base 2 of the soil loss monitoring device is rotated so that the light emitted by the laser 7 on the mounting base 2 is irradiated on the scale 6 of the insertion rod 1 in other soil loss monitoring devices. By observing the change of the scale 6, the settlement change of the soil can be preliminarily determined.

[0072] According to an embodiment of the present invention, on the other hand, a soil loss monitoring method is provided, which is applied to a soil loss monitoring device. The structure of the soil loss monitoring device is the same as that of the soil loss monitoring device in the above embodiment, and will not be repeated herein.

[0073] The soil loss monitoring method includes the following steps:

[0074] Step 1: Select multiple measuring points in the detection area and set up a soil loss monitoring device at each measuring point;

[0075] According to the size of the detection area, the location and number of the measuring points are reasonably determined. Then, a soil loss monitoring device is set at each measuring point. The installation method of the soil loss monitoring device is to insert the rod 1 vertically into the ground. The length of the inserted part is about one third of the length of the rod body.

[0076] After the soil loss monitoring device is inserted into the ground, the level bubble meter 5 on the mounting base 2 can be used to calibrate whether the mounting base 2 and the insertion rod 1 are tilted, and adjustments can be made in time.

[0077] In addition, the light emitted by the laser 7 on the mounting base 2 of the soil loss monitoring device can be irradiated on the scale line 6 of the other soil loss monitoring device insertion rod 1. When the detection area is a plane, the insertion depth of the insertion rod 1 can be changed to ensure that the light emitted by the laser 7 can be irradiated on the scale line 6 of the other soil loss monitoring device insertion rod 1.

[0078] Step 2: Each soil loss monitoring device lowers the distance measuring device 31 to the ground through its lowering device 32, and then records the initial height position of the distance measuring device 31;

[0079] The driving member 321 (motor) is started, and the driving member 321 rotates to lower the connecting rope 322, thereby lowering the distance measuring device 31. When the distance measuring device 31 reaches the ground, the tension of the connecting rope 322 decreases, and the driving member 321 senses the decrease in the tension of the connecting rope 322 and stops working.

[0080] At this time, the data reading device 33 reads the height position of the distance measuring device 31 and displays it on the display screen 4 . The staff can record the data and record the height position at this time as the initial height position of the distance measuring device 31 .

[0081] Step 3, reading the current height position of the distance measuring device 31 in each soil loss monitoring device at a certain time interval;

[0082] The soil loss monitoring device is placed still, and the height position of each distance measuring device 31 in each soil loss monitoring device can be recorded at regular intervals.

[0083] By comparing the current height position of the distance measuring device 31 at the current moment with the initial height position, the soil settlement value at the location during this period of time can be obtained.

[0084] Step 4: Calculate the soil settlement value at the corresponding measuring point according to the height position data of the distance measuring device 31 measured by the soil loss monitoring device;

[0085] At the end of monitoring, the current height position of each distance measuring device 31 in each soil loss monitoring device is read and recorded, and recorded as the final height position. The settlement value of each distance measuring device 31 during the entire monitoring period can be calculated by using the two data of the final height position and the initial height position, and then the soil settlement value at the corresponding measuring point of each soil loss monitoring device can be calculated. Combined with the soil settlement values ​​at each time recorded in step three, information such as the soil settlement rate at the measuring point during the entire monitoring period can be obtained.

[0086] Specifically, the soil settlement value at the measuring point is equal to the average value of the sum of the difference between the current height position and the initial height position of each distance measuring device 31 in the soil loss monitoring device. In this embodiment, each soil loss monitoring device is provided with two distance measuring devices 31, and the soil settlement value at a certain measuring point is calculated as follows: the initial height position of one distance measuring device 31 is recorded as H 1-1 , the final height position is recorded as H 1-2 , the initial height position of the other distance measuring device 31 is recorded as h 1-1 , the final height position is recorded as h 1-2 , through the formula The soil settlement value at the corresponding measuring point of the soil loss monitoring device during the monitoring period can be calculated. Similarly, the soil settlement value at other measuring points can be calculated according to this formula.

[0087] Step 5: Determine the consistency of soil loss in the test area based on the soil settlement value at each measuring point.

[0088] like Figure 3 As shown, taking two adjacent soil loss monitoring devices as an example, the initial height position of a distance measuring device 31 in the first soil loss monitoring device 8 is recorded as H 1-1 , the final height position is recorded as H 1-2 , the initial height position of the other distance measuring device 31 is recorded as h 1-1 , the final height position is recorded as h 1-2 , then the soil settlement value at the first measuring point corresponding to the first soil loss monitoring device 8 is Similarly, the initial height position of a distance measuring device 31 in the second soil loss monitoring device 9 is recorded as H 2-1 , the final height position is recorded as H 2-2, the initial height position of the other distance measuring device 31 is recorded as h 2-1 , the final height position is recorded as h 2-2 , then the soil settlement value at the second measuring point corresponding to the second soil loss monitoring device 9 is Then the starting height difference between the first measuring point and the second measuring point is Then the final height difference between the first measuring point and the second measuring point is The height difference of soil loss between the first measuring point and the second measuring point is H 5 =H 4 -H 3 By H 5 The difference in soil loss at the two measuring points can be determined, and the soil settlement values ​​of all measuring points can be calculated and analyzed based on this, so as to determine whether the degree and rate of soil loss in the entire detection area are stable and consistent.
