[0002] Grain storage is a crucial link in ensuring national food security. During grain storage, temperature changes within the grain pile are a key factor affecting grain quality and safety. Excessively high temperatures or the formation of localized hotspots within the grain pile can lead to mold and spoilage. Therefore, real-time and accurate monitoring of grain pile temperature is essential.

[0003] Currently, temperature measurement of grain piles is typically performed using temperature measuring rods. However, traditional grain pile temperature measuring rods have some technical drawbacks in practical applications. For example, some rods have complex structures, making installation and disassembly inconvenient and affecting measurement efficiency. Furthermore, the temperature probes are in direct contact with the internal environment of the grain pile, making them prone to damage and resulting in a short service life. Utility Model Content

Detailed Implementation

[0023] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0024] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0025] like Figures 1-6 The illustrated grain pile temperature measuring rod structure includes several tubes 1, with adjacent tubes 1 coaxially and detachably connected. The lower end of the lowest tube 1 has a tapered member 2. The lower end of the tube 1 extends to form a threaded connector 11, and the upper end of the tube 1 extends to form a threaded sleeve 12. Adjacent tubes 1 are coaxially threadedly connected to each other via the threaded connector 11 and the threaded sleeve 12. The upper end of the tapered member 2 extends to form a threaded sleeve, and the tubes 1 and the tapered member 2 are coaxially threadedly connected to each other via the threaded connector and the threaded sleeve. This connection method makes the assembly and disassembly of the temperature measuring rod very convenient, meeting the needs of grain pile temperature measurement at different depths. Furthermore, it can be installed and removed one by one, and the tapered member reduces the resistance when inserted into the grain pile, making it very convenient to use. In some embodiments, the tubes are made of stainless steel.

[0026] Each tube 1 is equipped with a temperature measuring component 3, which includes a connector 31, a junction box 32, and several temperature probes 33. The junction box 32 contains a circuit board 321, which integrates a battery 322 and a wireless communication module 323. The battery 322 provides power to the entire temperature measuring component 3. The wireless communication module 323 uses LoRa or NB-IoT wireless communication and transmits the temperature data collected by the temperature probes 33 wirelessly, for example, to a remote monitoring center or handheld device, thereby achieving real-time monitoring and remote management of the grain pile temperature. This integrated design reduces external wiring and improves the system's reliability and convenience. In a preferred embodiment, the junction box 32 has a cylindrical structure, with its outer wall fitting tightly against the inner wall of the tube 1. A sealing ring 5 is provided between the outer wall of the junction box 32 and the inner wall of the tube 1. The sealing ring 5 effectively prevents external moisture and dust from entering the junction box 32, protecting the internal electronic components and improving the durability and stability of the temperature measuring component 3.

[0027] Each temperature probe 33 is fitted with a heat-conducting pipe 34 on its outer side. The lower end of the heat-conducting pipe 34 is connected to a positioning seat 35, which is connected to a connecting seat 31. The upper end of the heat-conducting pipe passes through the bottom of the junction box 32 and is connected to the junction box 32. The temperature probe 33 extends into the heat-conducting pipe 34 from its upper end, and the upper end of the temperature probe 33 is connected to a circuit board 321. In some embodiments, the heat-conducting pipe 34 is configured as a ceramic tube, and the upper end of the temperature probe 33 is sealed to the upper end of the heat-conducting pipe 34. The heat-conducting pipe 34 is filled with thermally conductive grease. The heat pipe 34 protects the temperature probe from damage caused by the environment in the grain pile and also prevents dust from covering the probe surface. The heat pipe and heat-conducting grease can quickly transfer heat from the grain pile to the temperature probe, improving the detection accuracy of the temperature probe. After being removed from the grain pile, the heat pipe can be rinsed with water without affecting the temperature probe. The heat pipe is made of ceramic tube, which has better corrosion resistance.

[0028] In some embodiments, two or more temperature probes are used. In this embodiment, four temperature probes are used. The average value of the four temperature probes can be taken as the temperature value to improve the detection accuracy. At the same time, when the temperature measuring rod is buried in the grain pile for a long time, if one of the temperature probes is damaged (the difference between the detector value of the damaged probe and the detection value of the other temperature probes exceeds the preset range), the average value of the other three normal temperature probes can be taken as the temperature value, thereby improving the overall service life of the temperature measuring rod.

[0029] The temperature measuring component 3 is located at the lower end of the tube body 1. The connecting seat 31 is detachably connected to the tube body 1. The outer wall of the tube body 1 has several circumferentially distributed guide grooves 13 in the area corresponding to the temperature probe 33. The side of the connecting seat 31 has several connecting holes 312. The tube body 1 has slots 16 corresponding to the connecting holes 312. The slots 16 and the connecting holes 312 are fastened together by bolts 4.

[0030] The connecting seat 31 has a threaded hole 311 at its center. The bottom center of the positioning seat 35 has a stud 351 that connects to the threaded hole 311. The top center of the positioning seat 35 has a connecting rod 352. The upper end of the connecting rod 352 passes through the bottom surface of the junction box 32 and is fastened by a nut 354. The lower end of the heat-conducting pipe 34 has a positioning post 341. The positioning seat 35 has a lower positioning hole 353 that engages with the positioning post 341. The upper end of the heat-conducting pipe 34 extends to form a positioning sleeve 342. The bottom surface of the junction box 32 has an upper positioning hole 324 that engages with the positioning sleeve 342. The junction box and the positioning seat are tightened together by the connecting rod 352 and the nut 354. The junction box and the positioning seat are supported by the heat-conducting pipe, thereby connecting the temperature measuring components into a whole. This makes the installation and disassembly of the connecting components and the pipe body more convenient.

[0031] In some embodiments, a protective sleeve 14 is provided on the inner wall of the pipe body 1 at a location corresponding to the guide channel 13, and the protective sleeve 14 is provided with a plurality of guide microholes 15. The protective sleeve 14 can prevent particulate matter in the grain pile from entering the pipe body through the guide channel 13, thereby keeping the guide channel 13 unobstructed.

[0032] Referring to the accompanying drawings, the method of using this utility model is as follows: First, thread a tube body together with a conical piece. Insert the conical piece and the tube body into a predetermined position in the grain pile. Then, connect a second tube body to the upper end of the tube body and insert the second tube body into the grain pile. Connect a third tube body to the upper end of the second tube body until the insertion depth meets the requirements. Then, repeat the above actions at other positions in the grain pile to insert the temperature measuring rod into different positions in the grain pile. The state of the temperature measuring rod after insertion into the grain pile is as follows. Figure 7 As shown in the figure, the dotted line indicates the depth of the temperature measuring component. The temperature measuring component transmits the detected values ​​to the remote monitoring center via a wireless communication module, thereby enabling accurate remote monitoring of the temperature at different locations and depths inside the grain pile.
