Description

Technical Field

[0001] This utility model relates to the field of monitoring instrument technology, specifically a portable corner structure laser soil erosion monitoring instrument. Background Technology

[0002] Soil and water loss monitoring is a core foundation for ecological environment governance and soil and water conservation planning. Especially in areas without fixed observation stations, portable monitoring equipment is essential for the rapid collection of key data such as slope erosion depth and cross-sectional morphology, providing accurate data for soil loss calculation. With the application of laser ranging technology in this field, portable laser soil and water loss monitoring instruments are gradually replacing traditional manual measurements (such as measuring ropes and levels), significantly improving monitoring efficiency and accuracy.

[0003] Existing portable laser soil erosion monitoring instruments mostly use exposed or simply protected laser rangefinder lenses. If not cleaned during use, dust and debris easily adhere to the lens surface, causing attenuation of laser emission and reception signals, resulting in ranging deviations. This directly affects the accuracy of soil erosion data (such as erosion depth and slope area). Furthermore, laser rangefinders are typically used for several hours at a time, and if the dust and debris on their surface are not cleaned, it will affect the next use. Therefore, we propose a portable corner-structured laser soil erosion monitoring instrument. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model moves the laser rangefinder inside the mounting housing downward by activating the electric push rod, so that the laser rangefinder moves to the outside of the protective housing, is removed from the protection, and can be used normally. During this process, the rack on the mounting housing drives gear A to rotate, so that the cleaning cloth on the rotating rod rotates synchronously. As the mounting housing descends, the surface lens of the laser rangefinder is cleaned. The same principle applies when storing it, which can avoid the process of inaccurate measurement or manual cleaning in subsequent use.

[0014] 2. This utility model allows you to press two positioning rods to move them towards the inner column and disengage them from the positioning holes. At this time, rotate the inner column 90° so that the positioning rods pass through the horizontal groove at that position and enter the vertical groove. Then, move the inner column to adjust the appropriate height. After reaching the appropriate height, rotate the inner column 90° so that the positioning rods enter the corresponding positioning holes through the spring force, completing the quick adjustment and making it convenient to use.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0021] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see the appendix Figure 1 - Appendix Figure 4 This utility model discloses a portable corner structure laser soil erosion monitoring instrument, comprising a protective shell 1, a box body 2 connected to one side of the inner side of the protective shell 1, an electric push rod 3 connected to the inside of the box body 2, a mounting shell 4 connected to the drive end of the electric push rod 3, a laser rangefinder 5 installed on the bottom side of the inner side of the mounting shell 4, two racks 6 connected to the outer side of the mounting shell 4, gears A7 meshing with the racks 6 away from the mounting shell 4, rotating rods 8 passing through the center of the inner side of each gear A7, both ends of the rotating rods 8 being rotatably connected to the inside of the protective shell 1, a cleaning cloth 9 connected to the center of the outer side of the rotating rods 8, a connecting rod 10 connected to the top side of the inner side of the mounting shell 4, a gear B11 connected to the outer side of one end of the connecting rod 10, a gear C13 installed below the gear B11, a stepper motor 12 connected to the drive end of the gear C13 at the center, the side of the stepper motor 12 away from the gear C13 being connected to the inner wall of the protective shell 1, and sliders 14 connected to the middle of the left and right sides of the box body 2.

[0023] In Embodiment 1, one end of an inner column 15 is rotatably connected to the bottom center of the protective shell 1. An outer column 21 is sleeved on the bottom side of the inner column 15. A screw 22 is connected to the bottom end of the outer column 21. A central disk 17 is connected to the inner center of the inner column 15. One end of a guide rod 18 is connected to the left and right sides of the central disk 17. The other end of the guide rod 18 is connected to a positioning rod 19. A spring 20 is sleeved on the outer side of both guide rods 18. One end of the spring 20 is connected to the outer wall of the central disk 17, and the other end of the spring 20 is connected to the outer wall of the positioning rod 19. Multiple positioning holes 23 are opened on the left and right sides of the outer column 21. The positioning holes 23 and the positioning rod 19 are correspondingly arranged. Multiple transverse grooves 24 that are adapted to the positioning holes 23 are opened inside the outer column 21. Vertical grooves 25 are provided on the front and rear sides of the outer column 21. The bottom ends of the two vertical grooves 25 penetrate the middle side of the multiple transverse grooves 24.

[0024] Specifically, by pressing the two positioning rods 19, they move towards the inner column 15 and disengage from the positioning hole 23. At this time, rotate the inner column 15 ninety degrees so that the positioning rods 19 pass through the horizontal groove 24 at this position and enter the vertical groove 25. Then, move the inner column 15 to adjust the appropriate height. After reaching the appropriate height, rotate the inner column 15 ninety degrees so that the positioning rods 19 enter the corresponding positioning hole 23 through the elastic force of the spring 20, thus completing the quick adjustment.

[0025] In embodiment 2, a rotary motor 16 is connected inside the top of the inner column 15, and the drive end of the rotary motor 16 is connected to the center of the bottom side of the protective shell 1.

[0026] Specifically, the protective shell 1 is rotated as a whole by the rotary motor 16, so that the laser rangefinder 5 on the protective shell 1 rotates synchronously to achieve horizontal rotation.

[0027] Working principle:

[0028] The device is threaded onto the fixed pile via the threaded connection between the screw 22 and the top of the fixed pile. In use, the electric push rod 3 moves the laser rangefinder 5 inside the mounting housing 4 downwards, allowing it to move outside the protective housing 1 and be removed from protection for normal use. During this process, the rack 6 on the mounting housing 4 drives the gear A7 to rotate, causing the cleaning cloth 9 on the rotating rod 8 to rotate synchronously. As the mounting housing 4 descends, it cleans the surface lens of the laser rangefinder 5. When the connecting rod 10 on the mounting housing 4 descends to the appropriate height, i.e., when the gear B11 on the connecting rod 10 engages with the gear C13 inside the protective housing 1, the laser rangefinder 5 moves entirely outside the protective housing 1 and stops moving, allowing normal use of the laser rangefinder 5. When an angle rotation is required, the stepper motor 12 drives the gear C13 to rotate. Since gear C13 is connected to gear B11, the cloth on gear B11 rotates, causing the mounting housing 4 to rotate. When the angle of the laser rangefinder 5 inside changes, because the electric push rod 3 is connected to the mounting shell 4, the electric push rod 3 moves synchronously within the protective shell 1 via the slider 14 on the box 2, completing the angle adjustment of the laser rangefinder 5. It also works with the rotary motor 16 to rotate horizontally. The laser rangefinder 5 is used to measure the cross-section of the area, and the water and soil loss data is calculated after the measurement. Both the rotary motor 16 and the stepper motor 12 are equipped with locking devices. When the height needs to be changed, the two positioning rods 19 are pressed to move them toward the inner column 15 and disengage them from the positioning hole 23. At this time, the inner column 15 is rotated 90 degrees, so that the positioning rods 19 pass through the horizontal groove 24 at this position and enter the vertical groove 25. Moving the inner column 15 can adjust the appropriate height. After reaching the appropriate height, the inner column 15 is rotated 90 degrees, so that the positioning rods 19 enter the corresponding positioning hole 23 through the elastic force of the spring 20, completing the quick adjustment and convenient use. The entire process is now complete.
