However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0023] Reference Figure 1-4 A variable-depth contact-type material level monitoring sensor includes a mounting base 1, a control box 2 on the surface of the mounting base 1, and a monitoring probe 5 on the bottom surface of a moving rod 4. The mounting base 1 serves as a connection platform between the device and the container, and is fixed to the top of the container with bolts. The control box 2 has an embedded microprocessor and a wireless communication module, which receives signals from the monitoring probe 5, calculates the material level height, and outputs real-time data to the control center, supporting remote monitoring. The monitoring probe 5 is also installed via a guide rod 8 mounting structure for easy subsequent removal. The monitoring probe 5 has an embedded pressure sensor that detects changes in material pressure. The material level height is adaptable to powder, granular, or liquid materials. The probe material is corrosion-resistant and high-temperature resistant, ensuring reliability in harsh environments. The bottom surface of the mounting base 1 is equipped with a connecting rod 3, and the bottom end of the connecting rod 3 is equipped with a moving rod 4. The bottom surface of the connecting rod 3 and the top surface of the moving rod 4 are equipped with sealing rings 7. The bottom end structure of the moving rod 4 is the same as that of the connecting rod 3. The connecting rod 3 serves as the main support structure of the device, connecting the mounting base 1 and the moving rod 4. As a mounting structure that increases the depth, the moving rod 4 carries the monitoring probe 5, and by installing multiple moving rods 4, the depth of material level monitoring can be adjusted to adapt to different container depths. The sealing ring 7 is made of silicone to prevent dust, liquid, or corrosive materials from seeping into the connection interface, protecting the internal structure from contamination or damage, and improving the durability of the device in high dust or humid environments.

[0024] A guide groove 11 is provided on the bottom surface of the connecting rod 3, and a positioning rod 10 is provided inside the guide groove 11. A positioning groove 9 is provided on the surface of the guide rod 8. The guide rod 8 serves as the installation connection structure between the moving rod 4 and the connecting rod 3. It is inserted into the guide groove 11 of the connecting rod 3 and cooperates with the positioning rod 10 through the positioning groove 9 on its surface to ensure accurate alignment during connection and prevent rotation or displacement. A telescopic assembly 12 is provided inside the guide groove 11. The telescopic assembly 12 includes a first damping rod 1201, a first compression spring 1202, and a moving plate 1203. The surface of the first damping rod 1201 is provided with the first compression spring 1202. The ends of the damping rod 1201 and the first compression spring 1202 are provided with movable plates 1203. When the guide rod 8 is not inserted, the movable plate 1203 blocks the fixing assembly 14. When the guide rod 8 is inserted, the movable plate 1203 is compressed. Since the side of the fixing block 1404 is inclined, the fixing block 1404 is compressed and moves into the movable groove 13. At this time, the first damping rod 1201 and the first compression spring 1202 are also compressed, which facilitates the subsequent connection between the fixing block 1404 and the fixing groove 15 on the guide rod 8. The connecting rod 3 has a movable groove 13 inside, which accommodates the fixing assembly 14 and lifts... Provided with a movable space, the interior of the movable slot 13 is equipped with a fixing assembly 14. The fixing assembly 14 includes a second damping rod 1401, a second compression spring 1402, a connecting plate 1403, and a fixing block 1404. The surface of the second damping rod 1401 is provided with the second compression spring 1402, and the ends of the second damping rod 1401 and the second compression spring 1402 are provided with the connecting plate 1403. The surface of the connecting plate 1403 is provided with the fixing block 1404. The fixing assembly 14 is arranged in a circumferential array of four groups. The second damping rod 1401 and the second compression spring 1402 drive the connecting plate 1403, pushing the fixing block 1404 to embed. The guide rod 8 has a fixed groove 15, which forms a firm lock. The inclined surface of the fixed block 1404 is designed to match the fixed groove 15, and under a certain external force, the fixed block 1404 can be squeezed into the movable groove 13, which facilitates subsequent disassembly and assembly. The fixed groove 15 and the fixed block 1404 cooperate to form a locking structure. The end of the moving rod 4 is provided with a guide rod 8, and the surface of the guide rod 8 is provided with a fixed groove 15. The surface of the connecting rod 3 is provided with a pin 6. The pin 6 is installed on the surface of the connecting rod 3 and inserted into the preset hole of the moving rod 4 as an auxiliary locking device to prevent the connection from loosening under extreme vibration or impact. Specific Implementation Example 2:

[0026] A variable-depth contact level monitoring sensor device, based on the basic structure in Specific Embodiment 1, further discloses the following: The operation of this variable-depth contact level monitoring sensor device is as follows: The operator selects an appropriate number of moving rods 4 according to the required container depth, and inserts them into the guide groove 11 of the connecting rod 3 via the guide rod 8. The positioning rod 10 cooperates with the positioning groove 9 to ensure precise alignment. Simultaneously, the first damping rod 1201 and the first compression spring 1202 of the telescopic component 12 drive the moving plate 1203 to compress, making way for the fixed component 14. The second damping rod 1401 and the second compression spring 1402 of the fixed component 14 push the fixed block 140. 4. The guide rod 8 is embedded in the fixing groove 15 to form a firm lock. The pin 6 is inserted into the preset hole of the connecting rod 3 and the moving rod 4 to further strengthen the connection. The sealing ring 7 ensures that the connection is dustproof and waterproof. After installation, the monitoring probe 5 is inserted into the container to contact the material. The pressure sensor senses the change in material pressure and transmits the signal to the control box 2. The microprocessor calculates the material level height and sends it to the control center in real time through the wireless communication module, supporting remote monitoring. If the depth needs to be adjusted or maintenance is required, the pin 6 can be pulled out and the fixing block 1404 can be squeezed by external force to make it return to the movable groove 13. The moving rod 4 can be quickly disassembled. The operation is simple and can be completed in a few minutes. The whole process is convenient and efficient and adaptable to various container depths and working conditions.

[0027] In summary:

[0028] The device employs a guide rod 8, a telescopic assembly 12, a fixing assembly 14, a fixing groove 15, and a pin 6. The guide rod 8 is inserted into the guide groove 11 on the bottom surface of the connecting rod 3. Through the cooperation of the positioning rod 10 and the positioning groove 9, the precise alignment of the moving rod 4 and the connecting rod 3 is ensured. At this time, the telescopic assembly 12 is compressed by the guide rod 8, and the fixing block 1404 is continuously squeezed. Due to the inclined surface design of the fixing groove 15 and the fixing block 1404, the second compression spring 1402 pushes the fixing block 1404 into the fixing groove 15, forming a solid locking structure. Combined with the pin 6, the connection is further reinforced, ensuring the stability of the moving rod 4 and the monitoring probe 5 in high vibration or impact environments. It enables quick assembly and disassembly and depth adjustment, making it not only easy to operate but also effectively adaptable to various containers and working conditions, greatly improving the practicality and reliability of the device.
