Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically a soil hydraulic erosion detection device. Background Technology

[0002] Water erosion is the entire process by which soil, soil body or other ground components are destroyed, eroded, transported and deposited under the action of precipitation, surface runoff and ground runoff. It is an important type of soil erosion. The water erosion or water erosion commonly referred to is different from soil erosion, which includes the loss of water and soil erosion.

[0003] Sloping farmland is affected by long-term cultivation erosion, and the soil shifts along the cultivation direction, resulting in changes in the topography of sloping farmland. Current technology mainly detects and monitors soil erosion by inserting sensors into the soil.

[0004] However, after the probe drives the sensor deep into the soil for detection, a large amount of soil will adhere to the surface of the probe and the sensor, requiring manual cleaning and maintenance. Manual cleaning is not only inefficient but also prone to leaving residues, causing the sensor to be covered by soil and affecting the detection quality. Secondly, traditional water erosion detection devices are not easy to protect the probe and sensor, making them very easy to be damaged by external impacts during transport. Utility Model Content

At the same time, the movement of the positioning shell can facilitate the cleaning and maintenance of the insertion rod and sensor by the adjusting component, thereby improving the accuracy of hydraulic erosion detection and solving the problem of traditional hydraulic erosion detection devices being difficult to clean and protect, as mentioned in the background art.

[0006] This utility model provides the following technical solution:

[0017] Compared with the prior art, the present invention provides a soil hydraulic erosion detection device, which has the following beneficial effects:

[0018] 1. In this soil hydraulic erosion detection device, the positioning component allows for the fixing of the positioning shell by rotating the knob to make it abut against the fixed shell.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Reference Figures 1-7 A soil hydraulic erosion detection device includes a detector 1, and further includes: two rods 2 fixedly connected to the detector 1; a soil compaction sensor 3 and a soil temperature and humidity sensor 4 electrically connected to the detector 1 at the ends of the rods 2 away from the detector 1; the soil temperature and humidity sensor 4 is a DP-R100W soil temperature and humidity sensor 4, with its probe fixedly connected to the rods 2 and its wire passing through the rods 2 and electrically connected to the detector 1; the soil compaction sensor 3 is an HD-3 (GPS + depth measurement) soil compaction meter, with its probe fixedly connected to the rods 2 and its wire passing through the rods 2 and electrically connected to the detector 1; and a fixing shell 5 fixedly connected to the detector 1, the fixing shell 5 being sleeved outside the rods 2. A positioning shell 7 is slidably connected to the fixed shell 5 via a positioning component. The positioning shell 7 is located inside the fixed shell 5. The positioning component is used to control the positioning shell 7 to move closer to or further away from the fixed shell 5. When in use, the positioning shell 7 is retracted into the fixed shell 5. After use, the positioning shell 7 is stretched out to protect the insertion rod 2, the soil compaction sensor 3, and the soil temperature and humidity sensor 4. A scraper 8 is installed inside the positioning shell 7 via an adjusting component. One side of the scraper 8 abuts against the surface of the soil compaction sensor 3 and the soil temperature and humidity sensor 4. The scraper 8 is made of rubber or silicone material, preferably rubber, to avoid damage to the sensors. When the adjusting component is working, the scraper 8 tends to rotate along the axis of the soil compaction sensor 3 and the soil temperature and humidity sensor 4.

[0033] Specifically, by using the soil compaction sensor 3 and the soil temperature and humidity sensor 4 together, the hydraulic erosion of the soil can be detected. After the detection is completed, the positioning shell 7 is adjusted by the positioning component to protect the insertion rod 2, the soil compaction sensor 3 and the soil temperature and humidity sensor 4. At the same time, the movement of the positioning shell 7 causes the adjusting component to drive the scraper 8 to move, thereby cleaning the insertion rod 2 and the sensor, thus laying a solid foundation for the accuracy and reliability of subsequent detection work.

[0034] The positioning component includes a pin 6 inserted into the positioning housing 7. The pin 6 has a threaded groove, and a knob 61 that abuts against the fixed housing 5 is threaded onto the threaded groove. The fixed housing 5 has a limit groove, and the pin 6 is slidably connected in the limit groove to limit the vertical movement of the pin 6.

[0035] Specifically, by setting the positioning component, rotating the knob 61 to make it abut against the fixed shell 5 can fix the positioning shell 7. At the same time, rotating the knob 61 to make it disengage from the fixed shell 5 can adjust the positioning shell 7, thereby facilitating the protection of the insertion rod 2 and the sensor by the staff and improving the convenience and practicality of the overall operation.

[0036] The adjusting components include: a positioning plate 9, fixedly connected inside the positioning shell 7 and sleeved outside the insertion rod 2; a sleeve 91 rotatably mounted on the positioning plate 9 and sleeved to the insertion rod 2; a first gear 92 fixedly sleeved on the sleeve 91; a tapered bevel at the end of the sleeve 91 away from the first gear 92, and the tapered bevel is annular for cleaning soil from the surface of the insertion rod 2; and a second gear 93 rotatably connected to the positioning plate 9; a limit rod fixedly connected to the bottom of the second gear 93; and a bearing fixedly connected to the end of the limit rod away from the second gear 93, which passes through the positioning plate 9. The outer ring of the bearing is fixedly connected to the positioning plate 9 to limit the second gear 93. The positioning plate 9 has an annular groove, and a limiting ring fixedly connected to the sleeve 91 is slidably connected in the annular groove to limit the rotation of the sleeve 91. The second gear 93 meshes with the first gear 92. A rotating disk 94 is fixedly connected to the second gear 93. The rotating disk 94 is located between the two insert rods 2. The rotating disk 94 has anti-slip grooves, and the anti-slip grooves are arranged in a ring around the axis of the rotating disk 94 to facilitate manual adjustment of the rotating disk 94 by the operator.

[0037] It also includes a positioning rod 95 rotatably connected to the sleeve 91. The end of the positioning rod 95 away from the sleeve 91 is fixedly connected to the scraper 8. The sleeve 91 is provided with a torsion spring 96. The two ends of the torsion spring 96 are fixedly connected to the positioning rod 95 and the sleeve 91 respectively. Since the two sensors and the insertion rod 2 have different diameters, when the positioning plate 9 drives the scraper 8 to move upward, it is affected by the squeezing of the insertion rod 2. The scraper 8 drives the positioning rod 95 to squeeze the torsion spring 96, so that it can move flexibly on the surface of the insertion rod 2. At the same time, when the positioning plate 9 drives the scraper 8 to move downward and contact the sensor, it is affected by the reaction force of the torsion spring 96, which can make the scraper 8 press against the sensor surface, thereby improving the cleaning quality of the sensor surface.

[0038] Specifically, by adjusting the positioning shell 7, when the positioning plate 9 moves, the tapered oblique opening on the surface of the sleeve 91 can efficiently clean the soil on the surface of the insertion rod 2. At the same time, after the positioning shell 7 is adjusted to the designated position, it pushes the rotating disk 94 to make the second gear 93 drive the two first gears 92 to rotate, which can adjust the angle of the scraper 8, thereby cleaning the sensor and avoiding soil residue from affecting the subsequent detection quality.

[0039] A protective cover is inserted into the end of the positioning shell 7 away from the fixing shell 5. The protective cover can be a plastic plug or a magnetic plug. Here, a magnetic plug is preferred because it has high stability and fast disassembly and assembly efficiency.

[0040] Specifically, the protective cover protects the sensor from external dust and moisture, thus extending its service life.

[0041] In this utility model, when the hydraulic erosion detection device is unfolded and used, the knob 61 on the pin 6 is rotated. After the knob 61 disengages from the fixed shell 5, the position of the positioning shell 7 is moved vertically so that it retracts into the fixed shell 5. Then the knob 61 is rotated again so that it is pressed against the fixed shell 5, thus fixing the positioning shell 7.

[0042] As the positioning shell 7 retracts, the insertion rod 2, soil compaction sensor 3, and soil temperature and humidity sensor 4 are exposed. At this time, the staff inserts the soil compaction sensor 3 and soil temperature and humidity sensor 4 into the soil to detect the soil temperature, humidity, and compaction.

[0043] After the inspection task is completed, the staff turns the knob 61 again to pull and adjust the positioning shell 7. During this process, the movement of the positioning shell 7 drives the positioning plate 9 inside to move, and the movement of the positioning plate 9 causes the sleeve 91 to slide on the surface of the insertion rod 2. The conical bevel on the sleeve 91 can effectively clean the soil adhering to the surface of the insertion rod 2. When the positioning shell 7 is adjusted to the designated position, the knob 61 is tightened again to fix the current state of the positioning shell 7.

[0044] After the fixing work is completed, the staff pushes the rotating disk 94 with their fingers. When the rotating disk 94 rotates, it drives the second gear 93 to rotate. When the second gear 93 rotates, it drives the two first gears 92 to rotate. When the two first gears 92 rotate, they drive the two sleeves 91 to rotate. When the sleeves 91 rotate, they drive the positioning rod 95 to rotate, causing the scraper 8 to clean the soil on the surface of the soil compaction sensor 3 and the soil temperature and humidity sensor 4. This effectively prevents the solidification phenomenon caused by soil residue, thereby ensuring the accuracy and reliability of subsequent detection work and providing a solid guarantee for the continuous monitoring of soil hydraulic erosion.
