[0016] 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.
[0017] Please see Figure 1-3This utility model provides a technical solution: an embedded installation assembly for a farmland soil moisture sensor, comprising an embedded installation assembly body 1 and a farmland soil moisture sensor 5. The farmland soil moisture sensor 5 is installed inside the embedded installation assembly body 1, and a sensor probe 501 and a cable 502 are installed on the farmland soil moisture sensor 5. An embedded positioning cylinder 3 is provided on the embedded installation assembly body 1 and is buried underground. The bottom of the embedded positioning cylinder 3 is connected to the sensor probe 501 through a through hole. A sealing installation cover 2 is provided at the upper end of the embedded installation assembly body 1 and is threadedly fastened to the embedded positioning cylinder 3. A limit rod 4 passes through the sealing installation cover 2, and a first sealing element 202 is interference-fitted into the through hole at the bottom of the sealing installation cover 2 and the limit rod 4. Furthermore, the first sealing element 202 is securely inserted into the limiting rod 4. A positioning plate 201 is welded to the upper end of the sealing mounting cover 2, and a bolt facing the limiting rod 4 passes through and is securely fastened to the positioning plate 201. This structure, through the secure connection between the sealing mounting cover 2 and the embedded positioning cylinder 3, allows the embedded mounting component body 1 to provide installation protection for the farmland soil moisture sensor 5. Simultaneously, the positioning plate 201 can cooperate with the limiting rod 4 via bolts to achieve positioning of the limiting rod 4, ensuring control of the insertion depth of the sensor probe 501. The cable 502 is inserted into the limiting rod 4. The bottom of the limiting rod 4 is also provided with a limiting plate 401 that movably engages with the sealing mounting cover 2. Evenly spaced fastening positioning grooves 405 are provided on the side of the limiting rod 4. Corresponding to the bolt positions on the positioning plate 201, this structure allows the positioning plate 201 to fasten the limiting rod 4 to the limiting rod 4 by bolts when the limiting rod 4 is adjusted to the appropriate position. The upper end of the limiting rod 4 is fastened to the fastening sleeve 403 by a threaded structure, and the fifth sealing element 404 is engaged inside the fastening sleeve 403. The fifth sealing element 404 and the cable 502 are sealed and penetrated. This structure, by fastening the cable 502 through the fastening sleeve 403, can reduce the entry of external moisture into the sealing mounting cover 2. At the same time, the rigid structure of the limiting rod 4 can protect the connection between the cable 502 and the farmland soil moisture sensor 5. The farmland soil moisture sensor 5 is fixed to the bottom of the limiting plate 401, allowing the farmland soil moisture sensor 5 to be installed. Inside the sealed mounting cover 2 and the embedded positioning cylinder 3, the limiting plate 401 and the limiting rod 4 are integrally formed. The outer ring of the limiting plate 401 is engaged with a fourth sealing element 402 that seals against the inner wall of the sealed mounting cover 2. This structure allows the limiting rod 4 to be adjusted according to the required measurement depth of the sensor probe 501, ensuring that the insertion depth of the sensor probe 501 can be flexibly adjusted based on the specific crop root distribution. The embedded positioning cylinder 3 has a T-shaped design, and positioning rods 301 are evenly welded and fixed to its side. Furthermore, the connection points between the embedded positioning cylinder 3 and the sealed mounting cover 2, as well as the sensor probe 501, are respectively secured with a second sealing element 302 and a third sealing element 303. This structure achieves this by burying the embedded positioning cylinder 3 underground.The foundation positioning of the main body 1 of the embedded installation component can be performed to ensure that the farmland soil moisture sensor 5 has a reliable positioning structure. The second sealing element 302 and the third sealing element 303 can respectively play a sealing role, reducing the entry of moisture into the main body 1 of the embedded installation component and ensuring the protection of the farmland soil moisture sensor 5. The sensor probe 501 penetrates through the bottom of the embedded positioning cylinder 3 and can reach the soil to realize the monitoring and processing of farmland soil moisture. The positioning rod 301 ensures the reliable embedding depth of the embedded positioning cylinder 3, guarantees the stability of the embedded positioning cylinder 3, and at the same time, the positioning rod 301 protects the sensor probe 501.
[0018] Working principle: When using the embedded installation assembly of this farmland soil moisture sensor, firstly, the cable 502 is threaded into the limiting rod 4, then the farmland soil moisture sensor 5 is fixed to the bottom of the limiting plate 401 with bolts. Next, the fastening sleeve 403 is tightened onto the limiting rod 4, so that the fastening sleeve 403 secures the cable 502 through the fifth sealing element 404. Then, the limiting rod 4 is inserted into the sealing mounting cover 2, and the limiting plate 401 is clamped inside the sealing mounting cover 2. The first sealing element 202 and the fourth sealing element 402 are used for sealing and positioning the limiting rod 4 and the limiting plate 401, respectively. Then, the sealing mounting cover 2 is tightened and fixed onto the embedded positioning cylinder 3. At this time, the sensor probe 501 penetrates the bottom of the sealing mounting cover 2, and the second sealing element... The sealing element 302 and the third sealing element 303 are used to seal and position the mounting cover 2 and the sensor probe 501, respectively. Then, the embedded positioning cylinder 3 is buried underground. The positioning rod 301 is used to ensure the burial depth and the stability of the embedded positioning cylinder 3. Then, the burial depth of the sensor probe 501 is further adjusted as needed. The limiting rod 4 is moved down under the positioning of the sealing mounting cover 2, so that the depth of the sensor probe 501 can be adjusted. Then, bolts are passed through the positioning plate 201. The limiting rod 4 is stabilized relative to the sealing mounting cover 2 through the cooperation of the bolts and the fastening positioning groove 405. The adjustable burial positioning of the embedded mounting component body 1 to the farmland soil moisture sensor 5 is realized, thus completing a series of tasks.
