Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring equipment, and in particular to an environmental monitoring device for cold chain warehousing. Background Art

[0002] With the rapid development of industries like fresh food and pharmaceuticals, cold chain warehousing, as a core link in ensuring the quality of perishable goods, has become increasingly important. During cold chain storage, environmental parameters such as temperature, humidity, and gas composition (especially ammonia and carbon dioxide concentrations) have a decisive impact on the storage quality of goods. Even slight fluctuations in these parameters can accelerate the deterioration of goods, shorten their shelf life, or even cause them to be scrapped, resulting in significant economic losses. Therefore, real-time and accurate monitoring of the cold chain storage environment has become a critical issue that the industry urgently needs to address.

[0003] Currently, most existing cold chain warehouse environmental monitoring devices on the market have numerous shortcomings. In terms of monitoring scope, most devices employ fixed-point monitoring, measuring only environmental parameters at specific locations. This fails to fully cover the entire storage space and fails to reflect the true state of the entire storage environment. Due to the large size of cold chain warehouses, significant temperature gradients and humidity differences can exist between different areas. This single-point monitoring approach can easily lead to distorted data and cannot provide a reliable basis for warehouse management.

[0004] In terms of monitoring accuracy, traditional monitoring devices are limited by sensor performance and installation methods, and are easily interfered with by factors such as moisture, dust, and condensation, resulting in increased sensor measurement errors. For example, when the humidity in a cold chain warehouse is high, moisture easily condenses on the surface of the temperature and humidity sensor, affecting the normal operation of the sensor and causing deviations in the measurement data. At the same time, some devices lack effective sensor self-cleaning functions. As the use time increases, dust and other pollutants accumulate on the sensor surface, further reducing monitoring accuracy, making it unable to meet the cold chain warehouse's demand for high-precision environmental monitoring. Therefore, we have proposed an environmental monitoring device for cold chain warehouses to address the above problems. Summary of the Invention

[0034] In this embodiment, the driving mechanism includes a moving hole 102, a moving seat 103, a screw rod 202 and a driving motor 201. The moving hole 102 is opened on the bottom inner wall of the shell 101, and the moving seat 103 is slidably installed on the top inner wall of the shell 101.

[0035] In this embodiment, two connecting seats 203 are fixedly installed at the bottom of the shell 101, and a same horizontal plate 204 is fixedly installed between the two connecting seats 203. A rectangular hole 206 is opened on one side of the driving seat 104, and the horizontal plate 204 passes through the rectangular hole 206.

The top of the rotating shaft 208 extends into the rectangular hole 206 and is fixedly installed with a rotating gear 209. The front side of the horizontal plate 204 is fixedly installed with a rotating gear 209. The moving gear 209 is meshed with the straight rack 205, and the bottom end of the rotating shaft 208 is fixedly connected to the threaded rod 2011. When the driving seat 104 moves, the rotating gear 209 rolls on the straight rack 205, thereby driving the rotating shaft 208 and the threaded rod 2011 to rotate, realizing the vertical movement of the connecting rod 105 and the temperature and humidity sensor 106, so that the monitoring device can collect environmental parameters at different heights in the cold chain warehouse, greatly expanding the monitoring range and improving the comprehensiveness and accuracy of the monitoring data.

[0036] In this embodiment, the guide mechanism includes a rotating rod 302, a sliding groove 303, and a sliding rod 304. The rotating rod 302 is rotatably mounted on the top of the support plate 301. The top of the rotating rod 302 is provided with a sliding groove 303. The sliding rod 304 is slidably mounted in the sliding groove 303. The top of the sliding rod 304 is rotatably mounted on the bottom of the fixed plate 307. The inner walls of the sliding groove 303 are provided with limit grooves 305. Limit seats 306 are fixedly mounted on both sides of the sliding rod 304, and the limit seats 306 are slidably connected to the corresponding limit grooves 305. The guide mechanism can effectively guide the connecting rod 105 as it moves up and down, ensuring stable vertical movement of the connecting rod 105 and preventing shaking or deviation of the connecting rod 105 during movement. At the same time, the cooperation between the limit grooves 305 and the limit seat 306 ensures the stable sliding of the sliding rod 304 in the sliding groove 303, further improving the stability and reliability of the device operation.

[0037] In this embodiment, pulleys 401 are installed on the sliding rod 304 and the connecting rod 105, and the transmission sleeves on the two pulleys 401 are provided with the same belt 402. The transmission structure of the pulleys 401 and the belt 402 enables the rotation of the threaded rod 2011 to be smoothly transmitted to the sliding rod 304, realizing the linkage between the various components of the device, providing a power transmission basis for the subsequent reciprocating movement of the push plate 603 and the realization of functions such as gas extraction and sensor cleaning, thereby ensuring the coordinated work of the entire monitoring device.

[0038] In this embodiment, a cleaning plate 604 is fixedly installed at the bottom of the pushing plate 603, and a cleaning sponge block 605 for cleaning the temperature and humidity sensor 106 is installed on the top of the cleaning plate 604. During the reciprocating movement of the pushing plate 603, the cleaning sponge block 605 can regularly clean the temperature and humidity sensor 106, effectively removing impurities such as water vapor and dust attached to the surface of the sensor, avoiding these impurities from affecting the monitoring accuracy of the sensor, thereby ensuring that the temperature and humidity sensor 106 works stably and accurately for a long time.

[0039] In this embodiment, a reciprocating screw 703 is rotatably installed on the other side of the gas monitoring tube 501, and the push plate 603 is threadedly mounted on the reciprocating screw 703. A driven bevel gear 704 is fixedly installed on one end of the reciprocating screw 703, and a driving bevel gear 705 is fixedly installed on the rotating rod 302, and the driving bevel gear 705 is meshed with the driven bevel gear 704. The rotation of the rotating rod 302 is transmitted to the reciprocating screw 703 through the meshing of the driving bevel gear 705 and the driven bevel gear 704, so that the reciprocating screw 703 drives the push plate 603 to move back and forth, thereby realizing the reciprocating motion of the piston 702 in the gas monitoring tube 501, completing the extraction and discharge of gas, ensuring the continuous gas monitoring, and improving the efficiency and accuracy of gas monitoring.

[0040] In this embodiment, a rotation groove is provided on the side where the support plate 301 and the fixed plate 307 are close to each other, and an annular groove is provided on the inner wall of the rotation groove. An annular seat is fixedly installed on the rotating rod 302 and the sliding rod 304, and the annular seat is rotatably connected to the annular groove. The rotation connection structure between the annular seat and the annular groove provides stable support and guidance for the rotation of the rotating rod 302 and the sliding rod 304, so that the rotating rod 302 and the sliding rod 304 can rotate flexibly during the operation of the device, while ensuring stability during the rotation process, reducing wear between components, and extending the service life of the device.

[0041] The working principle of the present invention is as follows: the temperature and humidity in the cold chain warehouse can be monitored by the temperature and humidity sensor 106. By starting the drive motor 201, the drive motor 201 can drive the screw rod 202 to rotate, and the screw rod 202 can drive the movable seat 103 and the drive seat 104 to move. The drive seat 104 can drive the temperature and humidity sensor 106 to move in the horizontal direction through the connecting rod 105. The movement of the drive seat 104 can drive the rotating shaft and the rotating gear 209 to move. Under the action of the spur rack 205, the rotating gear 209 can rotate while moving. The rotating gear 209 can drive the threaded rod 2011 to rotate through the rotating shaft. The threaded rod 2011 can drive the connecting rod 105 and the temperature sensor to move downward through the threaded groove 2010. The connecting rod 105 can be moved vertically by the rotating rod 302 and the sliding rod 304. The upper guide prevents the connecting rod 105 from rotating with the threaded rod 2011. The temperature and humidity at different positions can be collected by the vertical and horizontal movement of the temperature and humidity sensor 106, thereby improving the accuracy of data collection. With the cooperation of the pulley 401 and the belt 402, the rotation of the threaded rod 2011 can drive the sliding rod 304 to rotate, and the sliding rod 304 can drive the rotating rod 302 to rotate through the limit seat 306. With the cooperation of the driving bevel gear 705 and the driven bevel gear 704, the rotating rod 302 can drive the reciprocating screw rod 703 to rotate, and the reciprocating screw rod 703 can drive the pushing plate 603 to move back and forth. The pushing plate 603 is driven by the cleaning plate 604 to the cleaning sponge block 605 for reciprocating movement. The movement of the cleaning sponge block 605 can realize the cleaning of the temperature and humidity sensor 106, effectively preventing the interference of water vapor, dust, etc. on the sensor.

[0042] When the push plate 603 moves back and forth, the push plate 603 can be driven to move back and forth by the cross bar 701. When the piston 702 moves to the left, the exhaust pipe 502 opens to exhaust the gas in the cold chain warehouse. The extracted gas is monitored by the ammonia sensor 504 and the carbon dioxide concentration sensor 505. When the piston 702 moves to the right, the exhaust pipe 503 opens to discharge the gas. The horizontal and vertical movement of the support plate 301 can realize the extraction of gas from different positions of the cold chain warehouse for monitoring. When the values ​​collected by the temperature and humidity sensor 106, the carbon dioxide sensor and the ammonia sensor 504 are abnormal, the alarm 108 can be activated by the controller 107 to sound an alarm. At the same time, the controller 107 sends an alarm message to the staff through the wireless sending module.

Specific embodiments are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea.
