Description

Technical Field

[0001] This invention relates to the field of temperature measurement equipment technology, and in particular to a temperature monitoring device for medical cold chain storage. Background Technology

[0002] Medical cold chain warehousing is a key link in ensuring the quality and safety of temperature-sensitive materials such as medicines, vaccines, and biological products. Its core lies in achieving full-process temperature control through a strict temperature control system, standardized facilities, and intelligent management. Among them, temperature monitoring devices are the core equipment for ensuring the quality and safety of temperature-sensitive materials (such as vaccines and biological products), and they must meet the requirements of high precision, real-time performance, and compliance.

[0003] For example, Chinese patent CN223064709U discloses a temperature monitoring device for medical cold chain storage. This device ensures that medical drugs are always in a low-temperature environment to ensure the storage effect of medical supplies and accurately detect the ambient temperature of medical supplies by vertically setting up a mounting frame on the mounting platform and placing the mounting frame on the side of the shelf for loading. While existing temperature monitoring devices for medical cold chain storage can be adjusted to monitor the temperature of the environment in real time, in practice, the presence of goods in some stacked areas can obstruct normal airflow, causing the temperature in those areas to be higher than in other areas. Furthermore, the limited air circulation during monitoring, coupled with the fact that the temperature monitoring device is moved while measuring, introduces certain detection errors, making it impossible to accurately measure the temperature in areas with many containers.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This solution uses a buffer component. Under the friction of the expansion sleeve, the guide seat slides along the surface of the spiral sleeve. During the movement, the guide seat needs to overcome the elasticity of the traction belt. Under the action of friction, the guide seat can reduce the movement speed to a certain extent, thereby extending the dwell time of the second monitor at the tray to a certain extent, and thus further reducing the monitoring error. 2. This solution, by setting up a compensation component, allows the gas inside the friction sleeve to enter the expansion sleeve through a pressure valve. At this time, the volume of the expansion sleeve will gradually increase, thereby further increasing the friction between the expansion sleeve and the guide seat, and thus further improving the control accuracy of the dwell time of the second monitor. The expansion sleeve is made of wear-resistant elastic material, which not only generates volume expansion, but also extends the service life of the expansion sleeve to a certain extent. 3. This solution uses a switching component to adjust the first monitor to the outside of the traction groove. When the buffer rod slides inside the buffer groove, it pulls the buffer belt, which applies a certain elastic force to the buffer rod, helping to keep the position of the first monitor stable. By extending the first monitor to the outside of the traction groove, normal airflow around the first monitor can be ensured, thereby effectively reducing the interference of external factors on the detection effect and helping to ensure the monitoring accuracy of the first monitor.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 10 The present invention provides a technical solution: A temperature monitoring device for medical cold chain storage includes a first monitor 28, a second monitor 37, and several sets of parallel columns 11. A support plate 12 is fixedly connected to the outer surface of each column 11, and a connecting frame 14 is fixedly connected to the upper outer surface of each column 11. A circulation component is provided inside each column 11. The circulation component includes a traction groove 24 embedded in the outer surface of the column 11. A guide seat 47 is slidably connected to the inner side of the traction groove 24. The outer surface of the guide seat 47 is fixedly connected to the second monitor 37. A driving part is provided inside the guide seat 47, which is used to drive the second monitor 37 to slide linearly inside the traction groove 24.

[0021] The drive unit includes a motor 15 fixedly connected to the upper outer surface of the connecting frame 14. A reciprocating lead screw 33 is fixedly connected to the lower end of the output shaft of the motor 15. The lower end of the reciprocating lead screw 33 extends into the traction groove 24. A spiral sleeve 36 is helically connected to the outer surface of the reciprocating lead screw 33. The guide seat 47 is located outside the spiral sleeve 36 and is slidably connected to the spiral sleeve 36. A top plate 32 is fixedly connected to the inner surface of the traction groove 24. The upper outer surface of the top plate 32 is rotatably connected to the reciprocating lead screw 33.

[0022] By adopting the above technical solution, the uprights 11 and pallets 12 form the main structure of the cold chain rack. The uprights 11 support the pallets 12, and the rack composed of the uprights 11 and pallets 12 is then fixed inside the medical cold chain warehouse. Medicines and medical devices are then stored on the surfaces of the pallets 12 at different heights. During the storage of medicines and medical devices, because the density of hot air is less than that of cold air, the temperature at the ceiling inside the warehouse will be higher than the temperature at the ground. To measure the temperature at different locations, a circulation component is installed. During operation, a timer controls the motor 15 to run electrically once at regular intervals. During the operation of the motor 15, its output shaft drives the reciprocating screw 3. 3 rotates, and the spiral sleeve 36 is connected to the reciprocating screw 33 by a spiral drive. As the reciprocating screw 33 rotates, it drives the spiral sleeve 36 to move along the axis of the reciprocating screw 33. The column 11 slides to support the guide seat 47 through the traction groove 24. The spiral sleeve 36 can drive the guide seat 47 to slide along the inside of the traction groove 24. The guide seat 47 drives the second monitoring instrument 37 to slide linearly in the vertical direction, thereby enabling the monitoring of the temperature at different positions. This helps to reduce monitoring errors and improve the accuracy of temperature monitoring. By comparing the temperature differences at different positions, it helps to classify and store medicines with different storage temperatures, thereby further improving the storage and refrigeration effect of medicines.

[0023] Specifically, such as Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, a buffer assembly is provided on the inner side of the tray 12. The buffer assembly includes an embedded air duct 42. A spring 40 is fixedly connected to the inner surface of the air duct 42. A top sleeve 39 is fixedly connected to the upper end of the spring 40. The lower end of the top sleeve 39 is open and communicates with the inside of the air duct 42. A limiting plate 41 is fixedly connected to the lower side of the outer surface of the top sleeve 39. The upper outer surface of the limiting plate 41 is fixedly connected to the inner surface of the top sleeve 39. The top sleeve 39 is made of elastic material.

[0024] The number of top sleeves 39 is several groups and they are arranged in a parallel array. A friction groove 38 is embedded in the outer surface of the front end of the support plate 12. A friction sleeve 43 is slidably connected to the inner side of the friction groove 38. One end of the friction sleeve 43 extends through to the outside of the friction groove 38 and the other end is open. The friction groove 38 is connected to the inside of the air guide pipe 42.

[0025] A retaining ring 34 is fixedly connected to the outer surface of the spiral sleeve 36. There are two sets of retaining rings 34, which are arranged in parallel vertically. A traction belt 35 is fixedly connected to the upper and lower ends of the outer surface of the guide seat 47. The end of the traction belt 35 away from the guide seat 47 is fixedly connected to the outer surface of the retaining ring 34. The traction belt 35 is made of elastic material and is symmetrically distributed on the front and rear sides of the guide seat 47. A compensation component is provided on the front side of the friction sleeve 43. The compensation component includes an expansion sleeve 45 fixedly connected to the outer surface of the front end of the friction sleeve 43.

[0026] By adopting the above technical solution, during the actual stacking of medicines, the medicine packaging boxes on the surface of the pallet 12 will, to a certain extent, obstruct air circulation, which will adversely affect the accuracy of temperature monitoring. Therefore, a buffer assembly is installed. The spiral sleeve 36 is fixedly supported by the retaining ring 34 and the traction belt 35 is slidably supported by the traction belt 35. In the initial state, the guide seat 47 is located near the upper retaining ring 34. When the storage box containing the medicine is placed on the upper side of the pallet 12, the lower end of the box will contact the upper surface of the top sleeve 39. At this time, the top sleeve 39 slides inside the air guide tube 42 under the weight of the box. 42 supports the top sleeve 39 via the limiting plate 41. Under external force, the top sleeve 39 undergoes elastic deformation. During its movement, the top sleeve 39 compresses the second spring 40. As the volume of the top sleeve 39 gradually decreases, the gas inside the top sleeve 39 enters the air guide pipe 42 and collects in the friction groove 38. As the amount of gas in the friction groove 38 gradually increases, the friction sleeve 43 slides along the inside of the friction groove 38 under the action of gas pressure. When the spiral sleeve 36 drives the guide seat 47 to move along the outer surface of the reciprocating screw 33 to the friction sleeve 43, the friction sleeve 43 will drive the expansion sleeve 45 and the guide... When the guide seat 47 contacts the outer surface of the expansion sleeve 45, it slides along the surface of the spiral sleeve 36 under the friction of the expansion sleeve 45. During the movement, the guide seat 47 needs to overcome the elasticity of the traction belt 35. Under the action of friction, the guide seat 47 can reduce the movement speed to a certain extent, thereby prolonging the dwell time of the second monitor 37 at the pallet 12. This allows the second monitor 37 sufficient time to monitor the temperature, further reducing monitoring errors. The more goods stored on the surface of the pallet 12, the more top sleeves 39 are pressed down, resulting in more air. Entering the friction groove 38 allows the friction sleeve 43 to extend outward a longer distance, thereby effectively increasing the friction between the expansion sleeve 45 and the guide seat 47. This further extends the dwell and monitoring time of the second monitor 37, helping to fully monitor the temperature around the cargo box. When the guide seat 47 contacts the outer surface of the retaining ring 34, the spiral sleeve 36 will drive the guide seat 47 to overcome resistance and move downward synchronously through the retaining ring 34. When the cargo is taken out from the upper side of the pallet 12, the top sleeve 39 moves in the opposite direction and resets under the elastic force of the second spring 40, thereby allowing the top sleeve 39 to protrude from the upper side of the pallet 12.

[0027] Specifically, such as Figure 3 and Figure 7 As shown, the outer surface of the expansion sleeve 45 is arc-shaped, and a pressure valve 44 is fixedly connected to the outer surface of the front end of the friction sleeve 43. The interior of the friction sleeve 43 is connected to the interior of the expansion sleeve 45 through the pressure valve 44. The expansion sleeve 45 is made of wear-resistant elastic material.

[0028] By adopting the above technical solution, when the gas pressure inside the friction sleeve 43 reaches the threshold of the pressure valve 44, the gas inside the friction sleeve 43 will enter the expansion sleeve 45 through the pressure valve 44. At this time, the expansion sleeve 45 will expand outward under the action of gas pressure, and the volume of the expansion sleeve 45 will gradually increase, thereby further increasing the friction between the expansion sleeve 45 and the guide seat 47, and further improving the control accuracy of the dwell time of the second monitoring instrument 37. The expansion sleeve 45 is made of wear-resistant elastic material, which can not only generate volume expansion, but also extend the service life of the expansion sleeve 45 to a certain extent.

[0029] Specifically, such as Figure 5 and Figure 8 As shown, a storage assembly is provided on the lower side of the traction groove 24. The storage assembly includes a first movable rod 25 fixedly connected to the inner surface of the traction groove 24. A swing rod 26 is rotatably connected to the outer surface of the first movable rod 25. A second movable rod 27 is fixedly and rotatably connected to the outer surface of the swing rod 26 away from the first movable rod 25. The second movable rod 27 is rotatably connected to the first monitoring instrument 28.

[0030] A support rod 16 is fixedly connected between two adjacent sets of columns 11. The upper outer surface of the support rod 16 is fixedly connected to the support plate 12. There are several sets of support plates 12 arranged in a parallel array. A diagonal brace 13 is fixedly connected between the support rod 16 and the support plate 12.

[0031] By adopting the above technical solution, the support rods 16 between the columns 11 can support the pallet 12, thereby improving the load-bearing capacity of the pallet 12. The diagonal bracing rods 13 can further improve the structural strength and connection stability of the storage device. The traction grooves 24 on the surface of the columns 11 are used to fix and support the first movable rod 25. The swing rod 26 can rotate around the first movable rod 25 as a fulcrum. The swing rod 26 supports the rotation of the first monitor 28 through the second movable rod 27. By storing the first monitor 28 inside the traction groove 24 of the storage slot 20, the first monitor 28 can be protected by the traction groove 24 when it is not working. This can effectively reduce the probability of accidental bumps to the first monitor 28 during the handling of goods, thereby effectively improving the safety and reliability of the first monitor 28 during use. By setting different types of monitoring equipment in different locations, different monitoring results can be compared and analyzed, which helps to further reduce monitoring errors.

[0032] Specifically, such as Figure 8 and Figure 10As shown, a switching component is provided on the outside of the first monitor 28. The switching component includes an active groove 29 embedded in the inner side of the first monitor 28. A storage groove 20 is embedded on the upper outer surface of the tray 12. A pressing seat 17 is slidably connected to the inner side of the storage groove 20. A limiting hole 18 is embedded on the lower outer surface of the pressing seat 17. A spring 19 is fixedly connected to the inner surface of the storage groove 20. The upper end of the spring 19 is located inside the limiting hole 18 and is fixedly connected to the pressing seat 17.

[0033] A movable block 30 is slidably connected to the inner side of the movable groove 29. A buffer rod 46 is fixedly connected to the outer surface of the movable block 30. The buffer rod 46 extends to the outside of the first monitor 28. A sliding groove 31 is embedded in the inner side of the support plate 12. An extrusion plate 21 is fixedly connected to the inner surface of the sliding groove 31. The side of the extrusion plate 21 away from the sliding groove 31 is slidably connected to the outer surface of the first monitor 28. The outer surface of the extrusion plate 21 is arc-shaped and made of elastic material. The upper outer surface of the extrusion plate 21 is in contact with the extrusion seat 17. A buffer groove 22 is embedded in the inner side of the support rod 16. A buffer strip 23 is fixedly connected to the inner surface of the buffer groove 22. The side of the buffer rod 46 away from the movable block 30 is fixedly connected to the buffer strip 23. The buffer rod 46 is located inside the buffer groove 22 and slides in contact with the buffer groove 22.

[0034] By adopting the above technical solution, in order to reduce the impact of the traction groove 24 on the air circulation effect, the first monitoring instrument 28 is equipped with a switching component when it is working. When the goods are placed on the surface of the bottommost pallet 12, the goods will press down on the compression seat 17. When the compression seat 17 slides down inside the storage groove 20, it will compress the spring 19. The compression seat 17 can limit the spring 19 through the limiting hole 18. During the downward movement of the compression seat 17, it will compress the compression plate 21. At this time, the bending arc of the compression plate 21 gradually decreases under the action of external force. The deformation of the compression plate 21 can push the first monitoring instrument 28. At this time, the swing rod 26 will push the first monitoring instrument 28 outward from the traction groove 24 during rotation. This allows the first monitor 28 to be adjusted to the outside of the traction groove 24. During its movement, the first monitor 28 pulls the buffer rod 46 through the movable groove 29 and the movable block 30. The movable block 30 can slide inside the movable groove 29, thus ensuring that the first monitor 28 remains vertical. When the buffer rod 46 slides inside the buffer groove 22, it pulls the buffer belt 23, which applies a certain elastic force to the buffer rod 46, helping to stabilize the position of the first monitor 28. By extending the first monitor 28 outside the traction groove 24, normal airflow around the first monitor 28 can be ensured, thereby effectively reducing the interference of external factors on the detection effect and helping to ensure the monitoring accuracy of the first monitor 28.

[0035] Working Principle: When the temperature monitoring device for medical cold chain storage is working, the rotation of the reciprocating screw 33 drives the spiral sleeve 36 to move along the axis of the reciprocating screw 33. The spiral sleeve 36 drives the guide seat 47 to slide along the inside of the traction groove 24. The guide seat 47 drives the second monitor 37 to slide linearly in the vertical direction, thereby monitoring the temperature at different locations. Under the gravity of the cargo box, the top sleeve 39 slides inside the air guide tube 42. Under the action of external force, the top sleeve 39 will undergo elastic deformation, and the gas inside the top sleeve 39 will enter the air guide tube 42 and collect in the friction groove 38. When the spiral sleeve 36 drives the guide seat 47 to move along the outer surface of the reciprocating screw 33 to the friction sleeve 43, the friction sleeve 43 will drive the expansion sleeve 45 to contact the outer surface of the guide seat 47. Under the action of friction, the guide seat 47 can reduce the movement speed to a certain extent, thereby enabling the temperature monitoring to be monitored. To a certain extent, the dwell time of the second monitor 37 at the support plate 12 is extended, thereby further reducing the monitoring error. The volume of the expansion sleeve 45 will gradually increase, thereby further increasing the friction between the expansion sleeve 45 and the guide seat 47, and thus further improving the control accuracy of the dwell time of the second monitor 37. By storing the first monitor 28 inside the storage slot 20 and the traction slot 24, the first monitor 28 can be protected by the traction slot 24 when it is not working. During the downward movement of the squeezing seat 17, the squeezing plate 21 will be squeezed. At this time, the bending arc of the squeezing plate 21 gradually decreases under the action of external force. The deformation of the squeezing plate 21 can push the first monitor 28, thereby adjusting the first monitor 28 to the outside of the traction slot 24, ensuring the normal flow of air around the first monitor 28, and thus effectively reducing the interference of external factors on the detection effect.
