Description

Technical Field

[0001] This utility model relates to the field of grain warehouse temperature and humidity monitoring technology, and in particular to a grain warehouse temperature and humidity monitoring device. Background Technology

[0002] Grain warehouse temperature and humidity monitoring is an important facility to ensure the safety of stored grain. It uses high-precision sensors to monitor the temperature and humidity changes inside the grain pile and the environment in real time. It usually has functions such as remote monitoring, data storage and analysis, which can effectively prevent problems such as mold and condensation, and significantly reduce grain storage losses. It is a core component of modern grain warehouse management.

[0003] A search revealed a grain warehouse temperature and humidity monitoring sensor disclosed in announcement number CN221593921U, which includes a grain warehouse body. Although the device can detect temperature and humidity at different points on the same plane, it requires friction with the grain when the sensor moves, increasing the difficulty of movement and making it prone to wear. Therefore, a grain warehouse temperature and humidity monitoring device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the sensor needs to rub against the grain when it moves, increasing the difficulty of movement and making it prone to wear. Therefore, this invention proposes a grain warehouse temperature and humidity monitoring device.

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

[0006] A grain storage temperature and humidity monitoring device includes multiple identical monitoring mechanisms installed in the grain storage. Each monitoring mechanism includes an installation pipe that is fixedly inserted through the top of the grain storage and fixed to the bottom of the grain storage. Two drive wheels arranged vertically are rotatably connected inside the installation pipe. A drive rope is connected between the two drive wheels. An installation plate is fixedly connected to one side of the drive rope. A temperature and humidity sensor is fixedly installed on one side of the installation plate. The rotation of the drive rope causes the temperature and humidity sensor to move up and down to measure the temperature and humidity at different heights of the grain storage. Multiple sets of air holes are opened on the circumference of the installation pipe, and the air holes are equidistantly distributed vertically.

[0007] A drive assembly is disposed on one side of the mounting tube for driving the drive wheel to rotate.

[0008] As a further embodiment of this utility model, a first sliding plate and a second sliding plate are slidably connected inside the mounting tube. Both the first and second sliding plates are fixed to one side of the drive rope. The surfaces of the first and second sliding plates are provided with through-holes. The other side of the drive rope passes through the through-holes. A connecting rod is fixedly connected between the second sliding plate and the first sliding plate.

[0009] As a further embodiment of this invention, at least one set of the air holes is located between the first and second sliding plates.

[0010] As a further embodiment of this utility model, a base plate is fixedly connected to the inner wall of the mounting tube, and a vertically arranged infrared ranging sensor and two horizontally arranged infrared ranging sensors are fixedly connected to the surface of the first sliding plate. The horizontally arranged infrared ranging sensors point to the air holes on the two vertical surfaces respectively.

[0011] As a further embodiment of this invention, two guide wheels are rotatably connected inside the mounting tube, and the drive rope passes around the guide wheels.

[0012] As a further embodiment of this utility model, the drive assembly includes a motor, which is fixed to one side of the top of the mounting tube, and one end of the motor output shaft passes through the mounting tube and is fixed to the drive wheel above it.

[0013] As a further embodiment of this utility model, a fan is provided on one side of the grain silo, and a connecting pipe is fixedly connected between the bottoms of the plurality of installation pipes, with the exhaust end of the fan fixed to one of the connecting pipes.

[0014] As a further embodiment of this utility model, a control box is fixedly connected to the top of the grain silo, and the control box is equipped with a data processing module and a wireless transmission module.

[0015] In this application, when measuring the temperature and humidity at different heights in the grain silo, the motor is started, which drives the drive wheel to rotate, thereby moving the drive rope. The drive rope moves the first sliding plate, the second sliding plate, and the mounting plate. The mounting plate moves the temperature and humidity sensor, thus facilitating the monitoring of temperature and humidity at different heights in the grain silo. At the same time, the setting of the first and second sliding plates can block the monitoring position, reducing measurement errors. The vertically set infrared distance sensor can monitor the height of the temperature and humidity sensor, making it easy to know the position of the temperature and humidity sensor. Meanwhile, the two horizontally set infrared distance sensors can sense distance changes through the air vents, thus making it easy to know the storage height of the grain in the grain silo, increasing the functionality of the equipment. Starting the fan can suck out small debris or grain that falls from the mounting pipe, preventing accumulation.

[0016] Beneficial effects: In this utility model, the grain warehouse temperature and humidity monitoring device can be set to move up and down through the temperature and humidity sensor, which can facilitate the monitoring of temperature and humidity at different heights of the grain warehouse. At the same time, the first and second sliding plates can block the monitoring position and reduce measurement errors.

[0017] In this utility model, the grain warehouse temperature and humidity monitoring device, through the setting of infrared ranging sensors, enables the monitoring of the height of the temperature and humidity sensors, making it convenient for people to know the location of the temperature and humidity sensors. At the same time, two horizontally set infrared ranging sensors can sense distance changes through air vents, thereby making it convenient for people to understand the storage height of grain in the grain warehouse and increasing the functionality of the equipment.

[0018] This invention enables the monitoring of temperature and humidity at different heights in a grain silo. The first and second sliding plates can also shield the monitoring location, reducing measurement errors. Furthermore, the infrared ranging sensor monitors the height of the temperature and humidity sensors, allowing users to easily understand the storage height of grain within the silo and enhancing the functionality of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, referring to Figures 1-3A temperature and humidity monitoring device includes: multiple identical monitoring mechanisms 3 installed in a grain silo 1, with one monitoring mechanism 3 positioned at the center of the grain silo 1 and the other monitoring mechanisms 3 evenly distributed around the center. Each monitoring mechanism 3 includes a mounting pipe 5, which is fixedly inserted through the top of the grain silo 1 and its bottom is fixed to the bottom of the grain silo 1. Two vertically arranged drive wheels 7 are rotatably connected inside the mounting pipe 5, and a drive rope 9 is drivingly connected between the two drive wheels 7. The drive wheels 7 and the drive rope 9 can also be replaced with synchronous pulleys and synchronous belts. One side of the drive rope 9 is fixedly connected to... Mounting plate 14, on one side of which a temperature and humidity sensor 15 is fixedly mounted. The temperature and humidity sensor 15 contains humidity-sensitive and temperature-sensitive elements and is a sensor device for measuring temperature and humidity. This is existing technology. The drive rope 9 rotates to move the temperature and humidity sensor 15 up and down to measure the temperature and humidity at different heights of the grain silo 1. Multiple sets of air holes 10 are opened around the circumference of the mounting tube 5. The air holes 10 are equidistantly distributed up and down. When the mounting plate 14 moves, it can move the temperature and humidity sensor 15, thereby facilitating the monitoring of temperature and humidity at different heights of the grain silo 1 and improving the flexibility of use.

[0025] A drive assembly is located on one side of the mounting tube 5 to drive the drive wheel 7 to rotate.

[0026] In this invention, a first sliding plate 11 and a second sliding plate 12 are slidably connected inside the mounting tube 5. Both the first sliding plate 11 and the second sliding plate 12 are fixed to one side of the drive rope 9. The surfaces of the first sliding plate 11 and the second sliding plate 12 are provided with through-holes, and the other side of the drive rope 9 passes through the through-holes. A connecting rod 13 is fixedly connected between the second sliding plate 12 and the first sliding plate 11. At least one set of air holes 10 is located between the first sliding plate 11 and the second sliding plate 12. The arrangement of the first sliding plate 11 and the second sliding plate 12 can block the monitoring position, reduce the flow of air between the upper and lower parts, and reduce measurement errors.

[0027] In particular, a base plate 16 is fixedly connected to the inner wall of the mounting tube 5, and a vertically arranged infrared ranging sensor 17 and two horizontally arranged infrared ranging sensors 17 are fixedly connected to the surface of the first sliding plate 11. The vertically arranged infrared ranging sensor 17 can monitor the height of the temperature and humidity sensor 15, making it easy for people to know the position of the temperature and humidity sensor 15. The horizontally arranged infrared ranging sensors 17 are respectively pointed to the two vertical air holes 10. The two horizontally arranged infrared ranging sensors 17 can sense the distance change through the air holes 10, thereby making it easy for people to know the storage height of grain in the grain warehouse 1 and increasing the functionality of the equipment.

[0028] This application can be used in the field of grain warehouse temperature and humidity monitoring, or in other fields applicable to this application.

[0029] Example 2, Reference Figures 1-3Based on Example 1, an improved grain warehouse temperature and humidity monitoring device is applied to the field of grain warehouse temperature and humidity monitoring.

[0030] In this invention, two guide wheels 8 are rotatably connected inside the mounting tube 5. The drive rope 9 passes around the guide wheels 8. The guide wheels 8 serve to tension the drive rope 9 and keep the two sides of the drive rope 9 close together, increasing the installation space for the components.

[0031] In particular, the drive assembly includes a motor 19, which is fixed to one side of the top of the mounting tube 5. One end of the output shaft of the motor 19 passes through the mounting tube 5 and is fixed to the drive wheel 7 above it. When the motor 19 is started, the motor 19 drives the drive wheel 7 to rotate, thereby causing the drive rope 9 to move.

[0032] It should be noted that a protective shell 18 is fixedly connected to one side of the mounting tube 5, and the motor 19 is located inside the protective shell 18.

[0033] In this utility model, a fan 2 is provided on one side of the grain silo 1, and a connecting pipe 6 is fixedly connected between the bottoms of multiple mounting pipes 5. The air extraction end of the fan 2 is fixed to one of the connecting pipes 6. When the fan 2 is started, it can suck out the small debris or grain that falls into the mounting pipe 5 to prevent accumulation.

[0034] In particular, a control box 4 is fixedly connected to the top of the grain silo 1. The control box 4 is equipped with a data processing module and a wireless transmission module. The monitored data is transmitted to the data processing module for processing. Then, the data processing module sends the processed data to the PC terminal through the wireless transmission module.

[0035] However, as is well known to those skilled in the art, the working principles and wiring methods of the temperature and humidity sensor 15, the infrared ranging sensor 17, the motor 19 and the control box 4 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
