Description

Technical Field

[0001] This utility model relates to the field of nitrogen content monitoring technology, specifically to a real-time soil nitrogen content monitoring device based on the Internet of Things. Background Technology

[0002] Soil nitrogen content is a key indicator in agricultural production, ecological environment monitoring, and soil fertility assessment, directly affecting crop growth and development, yield and quality, and ecosystem balance. Traditional methods for monitoring soil nitrogen content rely heavily on manual sampling and laboratory chemical analysis, which are cumbersome, time-consuming, and costly. Furthermore, they cannot achieve real-time dynamic monitoring of soil nitrogen content, making it difficult to meet the needs of precision agriculture for rapid feedback and timely regulation of soil nutrients.

[0003] With the widespread application of IoT technology in environmental monitoring, various real-time monitoring devices have emerged. However, existing soil nitrogen content monitoring devices still have shortcomings in their structural design: the connection between the monitoring probe and the main body of the device mostly adopts traditional methods such as threaded fixing and bolt locking. Installation and disassembly require tools, making operation inconvenient. Furthermore, under conditions such as long-term soil burial and environmental vibration, problems such as loosening and jamming can easily occur, affecting monitoring stability. At the same time, some devices lack buffer protection design in their connection structure, making the monitoring probe susceptible to damage from squeezing and collisions during installation or transportation, reducing the device's lifespan. In addition, the connection structure of existing devices has poor versatility, making it difficult to adapt to monitoring probes of different specifications, thus limiting the applicability of the devices. Therefore, there is an urgent need for a real-time soil nitrogen content monitoring device with a simple structure, convenient installation and disassembly, stable connection, and protective functions to overcome the shortcomings of existing technologies. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a real-time soil nitrogen content monitoring device based on the Internet of Things.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A real-time soil nitrogen content monitoring device based on the Internet of Things, comprising:

[0007] A carrier box is used to hold electronic components;

[0008] The mounting frame is fixed to the surface of the carrier box;

[0009] The spring is mounted on the carrier box along the height direction of the mounting frame.

[0010] A pair of hook-shaped plates, each penetrating one opposite side of the mounting frame, comprising:

[0011] The guide section slopes downwards from the outside of the mounting frame toward the inside of the mounting frame and penetrates the mounting frame.

[0012] The limiting section is fixed to one end of the guide section located inside the mounting frame, and the combined shape of the limiting section and the guide section is "hook" shaped;

[0013] The anti-detachment section is fixed to one end of the guide section located outside the mounting frame;

[0014] The plug-in block is inserted into the mounting frame along the center line in the height direction of the mounting frame. The distance between the far ends of the two limiting segments is greater than the length of the plug-in block, and the distance between the near ends of the two limiting segments is less than the length of the plug-in block.

[0015] Preferably, the angle between the guide section and the limiting section of the "hook"-shaped plate is 120-150°, and the outer surface of the guide section is provided with a guide slope with an inclination angle of 30-45° for the extrusion installation of the plug-in block.

[0016] Preferably, the inner side of the limiting section of each of the two "hook" shaped plates is provided with an elastic rubber pad, the thickness of which is 1-2mm, to buffer the squeezing force during the installation of the plug block.

[0017] Preferably, a monitoring probe is fixedly installed at the bottom end of the plug-in block, and the monitoring probe is plugged into the soil.

[0018] Preferably, a monitoring probe is fixedly installed at the bottom end of the plug-in block, and the monitoring probe is plugged into the soil.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] Installation and disassembly are highly efficient and convenient: Through the cooperative design of the "hook"-shaped plate and the plug-in block, and by utilizing the inclined structure of the guide section and the spacing characteristics of the limiting section, the plug-in block can be directly squeezed and installed without the need for additional tools, saving time and effort in the installation process; during disassembly, it is only necessary to rotate the device and squeeze the plug-in block, and the limiting section will automatically separate by means of spring contraction and the gravity of the "hook"-shaped plate itself, completing the quick disassembly of the plug-in block, which greatly improves the efficiency of device maintenance and probe replacement.

[0021] Stable and reliable connection: The distance between the near ends of the limiting sections of the two "hook"-shaped plates is less than the length of the plug-in block, while the distance between the far ends is greater than the length of the plug-in block. This ensures that the plug-in block can be stably clamped by the limiting sections after installation, effectively preventing loosening of the connection under conditions such as soil vibration and buried collision. This ensures the installation stability of the monitoring probe and the accuracy of the monitoring data. At the same time, the anti-detachment section adopts a circular baffle structure with a diameter larger than the cross-sectional diameter of the guide section, which can prevent the "hook"-shaped plates from falling off the mounting frame, further improving the structural reliability.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figure 1-4 As shown, a real-time soil nitrogen content monitoring device based on the Internet of Things includes:

[0031] Carrier box 1 is used to carry electronic components;

[0032] Mounting frame 11 is fixed to the surface of carrier box 1;

[0033] Spring 12 is mounted on carrier box 1 along the height direction of mounting frame 11;

[0034] A pair of hook-shaped plates 2, each penetrating one opposite side of the mounting frame 11, comprising:

[0035] The guide section 21 extends downward from the outside of the mounting frame 11 toward the inside of the mounting frame 11 and passes through the mounting frame 11.

[0036] The limiting segment 22 is fixed to one end of the guide segment 21 located inside the mounting frame 11, and the combined shape of the limiting segment 22 and the guide segment 21 is a "hook" shape.

[0037] The anti-detachment section 23 is fixed to one end of the guide section 21 located outside the mounting frame 11. The anti-detachment section 23 is a circular baffle structure with a diameter larger than the cross-sectional diameter of the guide section 21.

[0038] The plug block 3 is inserted into the mounting frame 11 along the center line in the height direction of the mounting frame 11. The distance between the far ends of the two limiting segments 22 is greater than the length of the plug block 3, and the distance between the near ends of the two limiting segments 22 is less than the length of the plug block 3. A monitoring probe 31 is fixedly installed at the bottom end of the plug block 3, and the monitoring probe 31 is inserted into the soil.

[0039] Specifically: When installing the plug-in block 3, the upper surface of the plug-in block 3 presses against the outer slopes of the two limiting sections 22 on both sides until the top of the limiting section 22 abuts against the lower surface of the plug-in block 3; when disassembling the plug-in block 3, the entire monitoring device is rotated while the plug-in block 3 is pressed, causing the spring 12 to contract and shorten until the plug-in block 3 separates from the end of the limiting section 22 away from the guide section 21. Due to the gravity of the hook-shaped plate 2 itself, the guide section 21 will slide outward along the mounting frame 11 until the distance between the near ends of the two limiting sections 22 is greater than the length of the plug-in block 3, thus completing the automatic disassembly of the plug-in block 3.

[0040] Furthermore, the angle between the guide section 21 and the limiting section 22 of the hook-shaped plate 2 is 120-150°, and the outer surface of the guide section 21 is provided with a guide slope with an inclination angle of 30-45° for the extrusion installation of the plug-in block 3.

[0041] Specifically, the guide section 21 and the limiting section 22 form an angle of 120-150°. This angle range has been optimized to provide sufficient guiding space for the insertion of the plug-in block 3, ensuring that the plug-in block 3 is subjected to uniform force and moves smoothly during the extrusion process. It also allows the limiting section 22 to form a stable clamping angle after the plug-in block 3 is installed in place, avoiding insufficient clamping force and loose connection due to an excessively large angle, or difficulty in inserting the plug-in block 3 and concentration of extrusion stress due to an excessively small angle. Meanwhile, the 30-45° guide slope on the outer surface of the guide section 21 can convert the axial pressure when the plug block 3 is inserted into the lateral component force that drives the "hook" shaped plate 2 to slide outward. Without the need to apply additional lateral force, the "hook" shaped plate 2 can automatically avoid the insertion, allowing the plug block 3 to be quickly and accurately embedded in the installation position. The inclined guide slope can also reduce the frictional resistance between the plug block 3 and the guide section 21, reduce wear during installation, and prevent the plug block 3 from skewing or getting stuck due to uneven force, further improving the convenience and stability of the installation operation.

[0042] Furthermore, the inner side of the limiting section 22 of the two hook-shaped plates 2 is provided with an elastic rubber pad, the thickness of which is 1-2mm, to buffer the squeezing force when the plug-in block 3 is installed.

[0043] Specifically, the elastic rubber pad inside the limiting section 22 is made of highly elastic and wear-resistant rubber. Its 1-2mm thickness is precisely calculated to ensure sufficient deformation capacity without excessive thickness that would reduce the clamping force of the limiting section 22 on the insertion block 3. During the extrusion installation of the insertion block 3, the elastic rubber pad undergoes elastic deformation with the extrusion force, transforming rigid extrusion into flexible contact. This effectively absorbs the impact force generated during installation, preventing scratches, deformation, and other damage to the surface of the insertion block 3 due to hard contact. Simultaneously, it buffers the reaction force on the limiting section 22, reducing fatigue wear on the "hook"-shaped plate 2 and extending the structural service life. In addition, the presence of the elastic rubber pad can increase the friction between the limiting section 22 and the plug block 3, further improving the stability of the connection between the two and preventing the plug block 3 from loosening and shifting when the device is subjected to vibration and shaking in the soil. At the same time, the flexibility of the rubber pad can also adapt to the slight dimensional deviations on the surface of the plug block 3, improve the adaptability of the connection structure, and ensure that plug blocks 3 of different specifications can maintain a stable clamping state after installation.

[0044] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
