[0002] Soil and water conservation is defined as the preventive and control measures taken against soil and water loss caused by human activities and natural factors. Soil and water conservation includes water conservation and soil conservation. The specific evaluation is the degree of water and soil conservation or loss in a selected area and within a specified time. Severe soil and water loss will lead to a reduction in cultivated land area, a decrease in soil fertility, a decrease in crop yields, and an increase in floods and waterlogging, which will increase the contradiction between man and land. Therefore, it is necessary to monitor soil and water conservation to provide scientific data reference and advance preventive measures for soil and water loss control, thereby ensuring the normal operation of industrial and agricultural work.

[0003] In the prior art, drones are used to take aerial photos of landforms, and the degree of soil loss can be analyzed by analyzing the photos of the landforms taken. The currently used drones include a drone body and a camera, and the camera is arranged on the drone body. However, since the landforms are only photographed by the camera, the photos taken by the camera cannot accurately analyze the water retention situation under the ground. Utility Model Content

A plurality of tripods 1 are fixedly arranged at the bottom of the drone body 7. A first sliding shell 10 is slidably sleeved on the tripod 1. A first electric push rod 11 is connected between the top of the first sliding shell 10 and the tripod 1. Specifically, the first electric push rod 11 is arranged on the upper side of the tripod 1. The telescopic end of the first electric push rod 11 is connected to the top of the first sliding shell 10. A first motor 20 is fixedly arranged in the first sliding shell 10. The output shaft of the first motor 20 is connected to a first drill rod 9. The upper end of the first drill rod 9 is rotatably arranged on the bottom of the first sliding shell 10. The first motor 20 can drive the first drill rod 9 to rotate on the bottom of the first sliding shell 10. Since the first sliding shell 10 can only slide on the tripod 1, the top of the first sliding shell 10 is connected to the first electric push rod 11, so that when the first drill rod 9 rotates, the telescopic end of the first electric push rod 11 is prevented from being subjected to a large torsional force, which causes the first drill rod 9 and the first electric push rod 11 to generate a large shake, so that the structure is subjected to reasonable force.

[0023] The passive bevel gear 4 is rotatably arranged on the bottom of the drone body 7. A driving assembly is connected between the passive bevel gear 4 and the drone body 7. The driving assembly can drive the passive bevel gear 4 to rotate at the bottom of the drone body 7. A second electric push rod 3, a guide rod 16 and a third electric push rod 15 are fixedly arranged on the bottom of the passive bevel gear 4. A soil moisture sensor 2 is fixedly arranged on the telescopic end of the second electric push rod 3. The soil moisture sensor 2 has a detection probe and faces downward. A second sliding shell 17 is slidingly sleeved on the guide rod 16. The top of the second sliding shell 17 is connected to the telescopic end of the third electric push rod 15. A second motor 18 is fixedly arranged in the second sliding shell 17. The output shaft of the second motor 18 is fixedly arranged A second drill rod 19 is fixedly connected, and the upper end of the second drill rod 19 is rotatably arranged on the bottom of the second sliding shell 17. Since the second sliding shell 17 can only slide on the guide rod 16, the top of the second sliding shell 17 is connected to the third electric push rod 15, so that when the second drill rod 19 rotates, the telescopic end of the third electric push rod 15 is prevented from being subjected to a large torsional force, which causes the second drill rod 19 and the third electric push rod 15 to produce a large shake, so that the force of the structure is reasonable; the second drill rod 19 and the second electric push rod 3 are symmetrical with respect to the central axis of the passive bevel gear 4, so that after the detection hole is drilled, the passive bevel gear 4 rotates 180° to drive the soil moisture sensor 2 to align directly above the detection hole;

During the rotation of the first drill rod 9, the first electric push rod 11 is used to drive the first sliding shell 10 to slide downward on the tripod 1, and the first sliding shell 10 drives the first motor 20 and the first drill rod 9 to move downward, so that the first drill rod 9 is inserted into the ground, and multiple first drill rods 9 rotate synchronously and move downward synchronously. The drone body 7 can be fixed on the ground before the drilling inspection to avoid the drone shaking, shifting or tipping during the subsequent drilling inspection, thereby ensuring the accuracy of the drilling inspection hole position; after the drone body 7 is fixed on the ground, the second drill rod 19 is driven to rotate by the second motor 18.

After the drilling is completed, the second drill rod 19 is driven to rise and exit above the ground by the third electric push rod 15, and the driving component drives the passive bevel gear 4 to rotate 180°, and the passive bevel gear 4 drives the second electric push rod 3 and the third electric push rod 15 to rotate 180°, so that the second electric push rod 3 drives the soil moisture sensor 2 to rotate to align above the dug detection hole, and the second electric push rod 3 drives the probe of the soil moisture sensor 2 to extend into the hole and insert it into the soil at the bottom of the hole. The soil moisture sensor 2 can be used to detect the moisture of the soil deep underground, and then the underground moisture retention can be obtained. Moreover, because the soil moisture in the deep hole is detected by drilling a hole first and then detecting the soil moisture in the deep hole, the moisture in the soil deeper underground can be detected, and it is also avoided that the soil moisture sensor 2 is directly inserted into the deep underground to cause damage to it.
