Description

Technical Field

[0001] This utility model relates to the field of grain depot management technology, and in particular to a non-contact grain pile temperature measurement system for monitoring grain pile temperature. Background Technology

[0002] Grain storage is a crucial link in ensuring national food security. In grain depots, the temperature of the grain pile is one of the key indicators for assessing the condition of stored grain. Excessively high internal temperatures in the grain pile can lead to problems such as grain overheating, mold growth, and pest infestation, seriously affecting grain quality and storage safety. Therefore, real-time and accurate monitoring of grain pile temperature is of paramount importance.

[0003] Traditional methods for measuring grain pile temperature mainly include manual rod insertion and wired cable temperature measurement. Manual rod insertion requires personnel to enter the grain depot, which is cumbersome, inefficient, and poses safety hazards, especially in large grain depots with numerous measurement points, making it time-consuming and labor-intensive. Furthermore, the fixed rods cannot measure the temperature of the grain pile from all angles. Therefore, there is an urgent need for an automated, full-range temperature measurement system to overcome the shortcomings of existing technologies. Utility Model Content

[0004] In order to solve the above-mentioned problems in the prior art, this utility model provides an automated, wide-range, and flexible non-contact grain pile temperature measurement system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A non-contact grain pile temperature measurement system includes a track connected to the top of the grain depot, a walking mechanism that can actively move along the track, a lifting support on the lower side of the walking mechanism, a lifting mechanism on the walking mechanism that drives the lifting support to rise and fall, and a temperature measuring component on the lifting support, the temperature measuring component including a radar microwave thermometer and a wireless communication module; the walking mechanism moves intermittently along the track, and when the walking mechanism stops moving, the radar microwave thermometer measures the temperature of the grain pile in the lower area.

[0007] By adopting the above technical solution: a track is laid on the top of the grain depot, and a traveling mechanism drives the radar microwave thermometer to move inside the grain depot. After moving to each end position, the traveling mechanism stops, and the radar microwave thermometer emits microwaves into the grain pile. The microwaves penetrate the grain pile to measure the temperature. Then, the traveling mechanism continues to move along the track to the next position to measure the temperature. Finally, the temperature of all areas of the grain pile in the entire grain depot is automatically measured. The measured data is transmitted to the control center through a wireless communication module. Using a radar microwave thermometer for non-contact automatic temperature measurement of the grain pile avoids the need for manual entry into the grain depot to insert a rod for temperature measurement, and can accurately measure the temperature of various areas in the grain depot. The temperature measurement position is more mobile and flexible. A lifting mechanism is used to lower the radar microwave thermometer to a position close to the grain pile, thereby improving the detection accuracy (reducing the propagation path of microwaves in the air).

[0008] Preferably, the tracks are S-shaped and are formed by connecting several track bodies at their ends. Each track body is provided with several connecting rods, the upper end of which is connected to the top of the grain depot, and the lower end of which is connected to the track body.

[0009] Preferably, the upper end of the connecting rod is provided with a connecting seat, and the upper end of the connecting rod is threadedly connected to the connecting seat. The connecting seat is provided with several connecting holes. The lower end of the connecting rod passes through the center of the track body and a nut is provided at both the upper and lower ends of the track body.

[0010] Preferably, the lower ends of the track extend outwards to form support rails. The traveling mechanism includes a frame and guide wheels at both ends of the top surface of the frame. The guide wheels are located on the top surface of the support rails. The top surface of the frame is provided with a drive wheel and a traveling motor that drives the drive wheel to rotate. The drive wheel abuts against the bottom surface of the support rails.

[0011] Preferably, the inner end of the support rail is provided with a limiting inclined surface between it and the track, and the guide wheel is configured as a conical wheel, with the conical surface of the guide wheel abutting against the limiting inclined surface.

[0012] Preferably, the lifting mechanism includes a lifting motor and a winding wheel connected to the lifting motor. The winding wheel is provided with a cable, the lower end of which is connected to the lifting bracket. The side of the frame is provided with several sliding seats, and a vertical sliding rod is provided inside each sliding seat. The lower end of the sliding rod is connected to the lifting bracket, and a limiting block is provided at the upper end of the sliding rod.

[0013] Preferably, both ends of the track are provided with limiting blocks, and the end faces of the limiting blocks are provided with buffer blocks.

[0014] Preferably, a guide rod is fixed to the lower end of one of the limiting blocks, a slider is provided on the guide rod, a fastening bolt is provided between the slider and the guide rod, a wireless charger is provided on the slider, a battery that can be charged by the wireless charger is provided on the top surface of the radar microwave thermometer, and a proximity switch is provided on the lifting bracket; when the walking mechanism moves along the track to the position of the wireless charger, the lifting mechanism drives the lifting bracket to rise until the battery is close to the wireless charger, the proximity switch detects the signal and causes the lifting mechanism to stop moving, at which time the wireless charger charges the battery.

[0015] Therefore, this utility model has the advantages of being flexible in use, automatically measuring temperature, and having a wide temperature measurement range. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] 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.

[0026] A brief introduction to the principle of radar microwave temperature measurement: The dielectric constant of a water-containing medium (such as grains, soil, etc.) is related to temperature. Temperature changes affect the polarity of water molecules, leading to a change in the dielectric constant of the medium. The propagation speed of microwaves in a medium is related to the dielectric constant of the medium. Therefore, by observing the difference in microwave propagation speed in a medium, the temperature of the medium can be derived using a formula. Radar microwave temperature measuring devices are existing technology and are commonly used for temperature measurement of water-containing media.

[0027] like Figures 1-7 A non-contact grain pile temperature measurement system is shown, comprising a track 1 connected to the top of the grain depot, a walking mechanism 2 that can actively move along the track 1, a lifting support 3 located on the lower side of the walking mechanism 2, and a lifting mechanism 4 on the walking mechanism 2 that drives the lifting support 3 to rise and fall. A temperature measuring component 5 is mounted on the lifting support 3, the temperature measuring component 5 including a radar microwave thermometer 51 and a wireless communication module. The walking mechanism 2 moves intermittently along the track 1. When the walking mechanism 2 stops moving, the radar microwave thermometer 51 measures the temperature of the grain pile in the lower area. Through the movement, stopping, and temperature measurement mode, this system can stop at any position on the track to measure the temperature of the grain pile. Since the grain surface height varies in different grain piles, the lifting mechanism lowers the radar microwave thermometer 51 to a position close to the grain surface, allowing microwaves to directly penetrate the grain pile, reducing microwave propagation in space, and thus improving temperature measurement accuracy (temperature is related to the propagation speed of microwaves in a medium). In some embodiments, the wireless communication module adopts a LoRa or NB-IoT wireless communication module.

[0028] In some embodiments, the track 1 is S-shaped and is formed by connecting several track bodies 11. Each track body 11 is provided with several connecting rods 12. The upper end of the connecting rod 12 is connected to the top of the grain depot, and the lower end of the connecting rod 12 is connected to the track body 11. The upper end of the connecting rod 12 is provided with a connecting seat 13, and the upper end of the connecting rod 12 is threadedly connected to the connecting seat. The connecting seat 13 is provided with several connecting holes 130. The lower end of the connecting rod 12 passes through the center of the track body 11. Nuts 14 are provided at both the upper and lower ends of the connecting rod 12. Each section of the track body is connected to the top of the grain depot through an independent connecting rod and connecting seat. The lower end of the connecting rod is connected to the track body through two nuts, which allows for convenient adjustment of the height of each track body, enabling precise docking between adjacent track bodies.

[0029] The lower ends of the track 1 extend outwards to form support rails 15. The traveling mechanism 2 includes a frame 21 and guide wheels 22 located at both ends of the top surface of the frame 21. The guide wheels 22 are located on the top surface of the support rails 15. The top surface of the frame 21 is provided with a drive wheel 23 and a traveling motor 24 that drives the drive wheel 23 to rotate. The drive wheel 23 abuts against the bottom surface of the support rail 15. A limiting inclined surface 150 is provided between the inner end of the support rail 15 and the track 1. The guide wheel 22 is configured as a conical wheel, and the conical surface of the guide wheel 22 abuts against the limiting inclined surface 150. The guide wheels travel along the top surface of the support rail, and the drive wheels travel along the bottom surface of the support rail.

[0030] like Figure 4 As shown, the lifting mechanism 4 includes a lifting motor 41 and a winding wheel 42 connected to the lifting motor 41. The winding wheel 42 is provided with a cable 43, and the lower end of the cable 43 is connected to the lifting bracket 3. The side of the frame 21 is provided with several sliding seats 44. The sliding seats 44 are provided with vertical sliding rods 45. The lower end of the sliding rods 45 is connected to the lifting bracket 3, and the upper end of the sliding rods 45 is provided with a limiting block 46.

[0031] like Figure 6As shown, both ends of the track 1 are equipped with limit blocks 6, and the end faces of the limit blocks 6 are equipped with buffer blocks 61. A guide rod 62 is fixed to the lower end of one of the limit blocks 6, and a slider 63 is mounted on the guide rod 62. A fastening bolt is provided between the slider 63 and the guide rod 62. A wireless charger 64 is mounted on the slider 63. A battery 52 that can be charged by the wireless charger 64 is mounted on the top surface of the radar microwave thermometer 51. A proximity switch 31 is mounted on the lifting bracket 3. When the walking mechanism 2 moves along the track 1 to the position of the wireless charger 64, the lifting mechanism 4 drives the lifting bracket 3 to rise until the battery 52 is close to the wireless charger 64. The proximity switch 31 detects the signal and causes the lifting mechanism 4 to stop moving. At this time, the wireless charger 64 charges the battery 52. ​​When the radar microwave thermometer's power is insufficient, it can be moved to the wireless charger at one end of the track for wireless charging.

[0032] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 7 As shown, track 1 is laid on the top of the grain depot. When not in use, the traveling mechanism 2 moves the radar microwave temperature sensor 51 to... Figure 6 The charging position is shown. In use, the lifting mechanism 4 lowers the radar microwave thermometer to near the grain surface. Then, the traveling mechanism 2 moves the radar microwave thermometer along the track. After moving to each position, the traveling mechanism stops, and the radar microwave thermometer emits microwaves to measure the temperature of the grain pile below that position. The detected signal is transmitted to the control center via a wireless communication module. The traveling mechanism 2 then continues to move along the track to the next position for temperature measurement. This temperature measurement system can automatically and flexibly move to measure the temperature of different positions on the grain pile, making it very convenient to use.
