Description

Technical Field

[0001] The present invention relates to a food cold chain transportation device, in particular to a food cold chain transportation device with a temperature monitoring and early warning function applied to the field of transportation and storage containers. Background Art

[0002] Cold chain transportation means that during the entire transportation process, no matter it is loading and unloading, changing the mode of transportation, replacing packaging equipment, etc., the transported goods are always kept at a certain temperature. Cold chain transportation of fruits generally chooses refrigerated transportation, and its temperature will be controlled at 0-7℃, which can effectively inhibit the respiration of fruits and the activity of surface microorganisms.

[0003] The specification of invention patent CN202110194356.3 discloses a cold chain logistics and transportation commodity quality monitoring and management system based on big data and image analysis technology. The application includes image acquisition module, image preprocessing module, temperature detection module, humidity detection module, ethylene concentration detection module, fruit hardness detection module, fruit quality detection module, data preprocessing module, modeling analysis server, database and display terminal. By detecting multiple parameters of fresh fruits to analyze the fruit deterioration assessment coefficient, the efficiency and accuracy of fresh fruit quality detection are improved, thereby reducing the rate of fresh fruit deterioration and labor costs, providing strong technical support for fresh fruit cold chain logistics transportation monitoring.

[0004] In the prior art, fruits that are worthy of high-cost cold chain transportation are themselves high-value fruits, such as mangoes, kiwis and cherries. These fruits are difficult to preserve for a long time at room temperature, so they need cold chain transportation to preserve them. In the above-mentioned invention patent, multiple detection data are used to conduct comprehensive detection of fruits, which improves the efficiency and accuracy of fresh fruit quality detection. However, some fruits that are at risk of spoilage cannot be identified from the appearance and are easily passed off as good ones by criminals, which may cause financial losses at the least and induce food safety accidents at the worst. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that some fruits with a risk of spoilage cannot be identified from the appearance and are easily passed off as good ones by lawless elements, which may cause financial losses at the least and induce food safety accidents at the worst.

[0006] In order to solve the above problems, the present invention provides a food cold chain transportation device with temperature monitoring and early warning functions, comprising a matching containing box and a cover plate, the cover plate being installed at the opening of the containing box, the containing box comprising a box body, a control terminal and a refrigeration structure being carried in the containing box, a mounting platform 1 being drilled at the opening of the box body, the cover plate being placed on the mounting platform 1, a sealing strip being connected between the containing box and the cover plate, the sealing strip being fixedly connected to the mounting platform 1, the cover plate comprising a cover body, a mounting platform 2 being drilled on the cover body, and the mounting platform 2 penetrating the cover body, a temperature early warning structure and a fixing plate being sequentially installed on the mounting platform 2 from bottom to top, a handle groove being drilled on the upper wall of the cover body, a pair of temperature sensors being fixedly connected to the lower wall of the cover body, the temperature early warning structure comprising a hard shell, a low-temperature hot melt adhesive being filled in the hard shell, and a plurality of through holes being drilled at the lower end of the hard shell, the lower end of the low-temperature hot melt adhesive extending to the outside through the through holes, and an electric heating network being buried in the fixing plate; The working method includes: the temperature sensor monitors the temperature in the containing box in real time, when the temperature is higher than the preset temperature, the refrigeration power of the containing box is increased, and when the temperature is lower than the preset temperature, the refrigeration power of the containing box is reduced, so as to realize real-time control of the temperature in the containing box. At the same time, the temperature sensor uploads the detected real-time data to the control terminal carried by the containing box, and the control terminal processes the real-time data, establishes a rectangular coordinate system with time (t) as the horizontal coordinate and temperature (T) as the vertical coordinate, makes a standard line with the preset maximum temperature on the rectangular coordinate system, and enters the real-time data into the rectangular coordinate system to form a continuous and smooth curve. In the process of temperature monitoring, the smooth curve located on the upper side of the standard line will form a shadow part with the standard line, and at the same time, the processing terminal calculates the shadow area, and judges the temperature control status in the containing box by the shadow area. When the shadow area exceeds the preset value, the control terminal sends out an early warning message, and starts the electric heating network set in the fixed plate to heat the low-temperature hot melt adhesive until the low-temperature hot melt adhesive melts and falls off from the hard shell and drips on the fruit in the containing box.

[0007] In the above-mentioned food cold chain transportation device with temperature monitoring and early warning function, fruits with too high storage temperature are marked to prevent them from being sold as good ones by criminals, causing financial losses, and triggering food safety accidents.

[0008] As a further improvement of the present application, when the processing terminal calculates the shadow area, when the smooth curve is located below the standard line for 30 consecutive minutes, the shadow area is reset to zero. When the temperature in the storage box is too high for a short time, shadow accumulation can be eliminated to increase the accuracy of detection.

[0009] As a further improvement of the present application, the sealing strip includes an elastic shell, which is filled with a semipermeable membrane matching the elastic shell, and the semipermeable membrane is filled with an air-hardening gel material. A through crack is drilled on the elastic shell, and the elastic shell is tightly attached to the through crack. After the storage box and the cover are installed, the elastic net will be squeezed out of the elastic shell along the through crack under the action of the weight of the cover, and attached to the junction of the storage box and the cover, and quickly solidified under the infiltration of air to form a sealing layer, completing the sealing of the connection between the storage box and the cover. On the one hand, the sealing of the storage box and the cover can be achieved, and on the other hand, the solidified air-hardening gel material will also fix the storage box and the cover. When the cover is reopened, the solidified air-hardening gel material needs to be destroyed first, which can prevent the transportation personnel from opening the cover during transportation, and it is not easy to switch the goods. At the same time, it is also convenient for the traceability of the transported fruits.

[0010] As a further improvement of the present application, the outer side of the semipermeable membrane is covered with an elastic net, which is woven from a plurality of elastic fibers. The elastic net can be restrained and protected to avoid excessive local deformation of the elastic net, which is not likely to cause damage and failure of the elastic net.

[0011] As another improvement of the present application, a plurality of marking structures are filled in the low-temperature hot melt adhesive, and the plurality of marking structures are suspended in the low-temperature hot melt adhesive. In the process of marking with the low-temperature hot melt adhesive, the falling marking structures will damage the surface of the fruit for marking, so that the marks formed on the surface of the fruit by the low-temperature hot melt adhesive used for marking are not easy to be removed, and are not easy to be replaced by inferior products.

[0012] As another improved supplement of the present application, multiple marking structures all include a pair of counterweight balls, and a connecting rope is fixedly connected between the two counterweight balls. The marking structure is designed as a chain structure, so that the marking structure is not easily embedded directly on the surface of the fruit under the impact of falling, thereby increasing the marking effect.

[0013] As another improvement supplement of the present application, the outer surfaces of the multiple weighted balls are coated with a homopolar coating, so that the multiple groups of marking structures can move away from each other after the low-temperature hot melt adhesive melts, thereby increasing the effective range of the marking.

[0014] As another improvement supplement of the present application, a plurality of grooves are chiseled on the surface of the counterweight ball, and the surface of the counterweight ball coated with the same polarity coating also appears uneven, thereby increasing the surface destructive capacity of the counterweight ball and enhancing the marking effect.

[0015] In summary, in the present application, a temperature sensor is used to monitor the temperature in the storage box in real time. The temperature sensor uploads the detected real-time data to the control terminal carried by the storage box. The control terminal processes the real-time data, establishes a rectangular coordinate system with time (t) as the horizontal coordinate and temperature (T) as the vertical coordinate, draws a standard line with a preset maximum temperature on the left side of the right angle, and enters the real-time data into the rectangular coordinate system to form a continuous and smooth curve. During the temperature monitoring process, the smooth curve located on the upper side of the standard line will form a shadow part with the standard line. At the same time, the processing terminal calculates the shadow area, and the shadow area is used to judge the temperature control status in the storage box. When the shadow area exceeds the preset value, the control terminal issues a warning message and starts the electric heating network set in the fixed plate to heat the low-temperature hot melt adhesive until the low-temperature hot melt adhesive melts and falls off the hard shell and drips on the fruits in the storage box. The fruits with too high storage temperature are marked to avoid being easily replaced by criminals, causing financial losses, and inducing food safety accidents.

[0016] At the same time, the marking structure is wrapped in low-temperature hot melt adhesive to achieve the use of falling marking structure to damage the surface of the fruit for marking, so that the traces left on the surface of the fruit by the low-temperature hot melt adhesive used for marking are difficult to remove and difficult to be replaced by inferior products. The marking structure is designed as a chain structure, so that the marking structure is not easily embedded in the surface of the fruit under the impact of falling, thereby increasing the marking effect.
