Description

[Technical field]

[0001] The present invention relates to the technical field of cold chain transportation equipment, and in particular to cold chain logistics transportation equipment and a monitoring system thereof. [Background technology]

[0002] Cold chain logistics and transportation equipment mainly refers to the production, storage, transportation and sales of refrigerated food. It is a systematic project to reduce food damage by keeping each link in a specified low temperature environment before consumption, which can ensure the quality of food. The existing cold chain transportation equipment is mainly composed of a large storage box and a cooling mechanism. By placing the items in the chamber of the storage box, the cooling mechanism transmits airflow into the chamber to achieve refrigeration of the items.

[0003] Although the above solution can store the product, there are still the following problems:

[0004] 1. First of all, due to the different categories of products, there are some differences in the temperature range suitable for refrigeration. If different categories of products are directly placed in one storage box, it is impossible to ensure that each product is in the corresponding cold storage environment during storage and transportation, which will affect the refrigeration of some products and reduce the refrigeration effect of the products;

[0005] 2. If different types of products are directly placed in one storage box, the subsequent personnel will need to open the storage box when taking one of the products. At this time, the cold air in the storage box will come into contact with the outside air, thus affecting the normal refrigeration of other products;

[0006] 3. Since the storage box is in a sealed state when cooling items, personnel cannot directly observe the internal temperature conditions, which will cause the temperature inside the storage box to be unable to be effectively controlled. [Summary of the invention]

[0040] like Figures 1 to 4 A cold chain logistics transportation equipment and a monitoring system thereof in the present invention include a conveying box 1 and a cooling mechanism 2 fixedly connected to the conveying box 1, wherein the cooling mechanism 2 is mainly composed of an air cooler, and the air cooler is mainly used to cool the airflow;

[0041] The cold chain transport equipment and monitoring system thereof in the present invention further include: a plurality of cooling boxes 3 with end covers 4, a main conveying pipe 5, a plurality of secondary conveying pipes 6 corresponding to the number of cooling boxes 3, a control element 9, a plurality of temperature sensors 10 corresponding to the number of cooling boxes 3, and a plurality of sensing elements 11 corresponding to the number of cooling boxes 3;

[0042] A plurality of cooling boxes 3 are fixedly connected to the conveying box 1 so that personnel can store items, and the end cover 4 is detachably connected to the cooling box 3, and the end cover 4 is mainly used to seal the cooling box 3;

[0043] The main delivery pipe 5 is fixedly connected to the delivery box 1, and one end of the main delivery pipe 5 is connected to the air cooler, which is mainly used for transmission cooling. The secondary delivery pipe 6 is connected to the main delivery pipe 5, and is connected to the cooling box 3 through the secondary delivery pipe 6. It is mainly used to transmit the airflow in the main delivery pipe 5 into the secondary delivery pipe 6, so as to cool the cooling box 3.

[0044] When the personnel disassemble the end cover 4 and the box body, the induction member 11 arranged on the box body senses that the end cover 4 is away, and transmits a signal to the control member 9 which is electrically connected to it and fixedly connected to the conveying box body 1. The control member 9 controls the electromagnetic valve 28 which is electrically connected to it and fixedly connected to the secondary conveying pipe 6. The electromagnetic valve 28 is closed, so that the cold air does not enter the cooling box 3. The secondary conveying pipe 6 on the cooling box 3 is in a sealed state due to the influence of the electromagnetic valve 28. Then the cooling will enter other chambers, which can greatly avoid the waste of cold air.

[0045] If the temperature in the cooling box 3 needs to be controlled, the temperature sensor 10 fixedly connected in the cooling box 3 senses the temperature rise or fall, and transmits a signal to the control component 9 electrically connected thereto. The control component 9 controls the solenoid valve 7 electrically connected thereto and fixedly connected to the secondary delivery pipe 6 to close or open. When the temperature in the cooling box 3 is too high, the solenoid valve 7 is in an open state, and when the temperature in the cooling box 3 is low, the solenoid valve 7 is in a closed state. It is worth mentioning that the control component 9 is a control panel. The personnel set the temperature sensed by the temperature sensor 10 on the control panel so that the temperature sensor 10 can sense the temperature and feed it back to the control panel, and the control panel controls the solenoid valve 7 to open or close.

[0046] Specifically, since the sensing element 11 includes a sensing block 12 fixedly connected to the bottom surface of the end cover 4, a sensing slot 13 for the sensing block 12 to enter is opened on the box body, and a distance sensor 14 is fixedly connected in the sensing slot 13. The distance sensor 14 and the sensing slot 13 are arranged opposite to each other, and the distance sensor 14 is electrically connected to the control element 9, when the sensing block 12 enters the sensing slot 13, the distance sensor 14 will sense the sensing block 12 and transmit a signal to the control panel, and the control panel controls the temperature sensor 10 and the solenoid valve 1 7 to start and the solenoid valve 2 8 to open, thereby indirectly reducing the waste of cold air.

[0047] Specifically, a fixing block 15 is fixedly connected to the end cover 4, and the fixing block 15 is affixed to a fixing block 2 16 fixedly connected to the cooling box 3, and a bolt 17 connected to the fixing block 15 is rotatably connected to the fixing block 2 16 through a thread, thereby increasing the fixing effect of the end cover 4.

[0048] Specifically, an air dehumidifier 18 electrically connected to the control panel is fixedly connected to the main conveying pipe 5. The air dehumidifier 18 is controlled by the control panel to dehumidify the conveyed airflow, thereby reducing the humidity in the air.

[0049] Specifically, since a spray head 19 is fixedly connected inside the main delivery pipe 5, a water pipe 20 is connected to the spray head 19, one end of the water pipe 20 extends to the outside of the main delivery pipe 5, a solenoid valve three 21 is fixedly connected to the water pipe 20, and the control component 9 is electrically connected to the solenoid valve three 21. The water pipe 20 is mainly used to transport water into the spray head 19, and the water transported through the spray head 19 contacts the airflow, thereby humidifying the airflow. The airflow can be humidified and dehumidified, thereby maintaining the humidity in the cooling box 3 at an appropriate humidity. During the dehumidification process, the control panel controls the solenoid valve three 21 to be in a closed state.

[0050] Specifically, by fixing and connecting the fan three 22 at one end of the main conveying pipe 5 away from the air dehumidifier 18, a filter frame 23 is provided on the fan three 22, the airflow is filtered by the filter frame 23, and then the airflow is transmitted by the fan three 22 to enter the main conveying pipe 5, thereby increasing the transmission effect of the airflow.

[0051] Specifically, a humidity sensor 24 is fixedly connected to the cooling box 3, and the humidity in the cooling box 3 is sensed by the humidity sensor 24, and a signal is transmitted to a control panel electrically connected thereto, and the control panel controls the opening and closing of the solenoid valve 3 21 or the opening and closing of the dehumidifier, thereby controlling the humidity in the cooling box 3 to maintain a suitable humidity.

[0052] Specifically, an exhaust pipe 25 is fixedly connected to the cooling box 3, and a fan 27 is connected to the exhaust pipe 25. A solenoid valve 26 is fixedly connected to the exhaust pipe 25. When the fan 27 is started, the airflow in the cooling box 3 is discharged to the outside, thereby realizing rapid replacement of the airflow in the cooling box 3.

[0053] Specifically, since the cooling box 3 is connected with an air intake pipe 28, the air intake pipe 28 is fixedly connected with a second fan 29, and the air intake pipe 28 is fixedly connected with a fifth solenoid valve 30, when the fifth solenoid valve 30 is opened, the second fan 29 transmits airflow through the air intake pipe 28 into the cooling box 3, thereby increasing the rapid replacement of the airflow in the cooling box 3;

[0054] Specifically, since the cooling box 3 is provided with insulation cotton 31, the insulation cotton 31 is rotatably connected to a bolt 2 32 whose end is threadedly connected to the cooling box 3. By removing the bolt 2 32, the insulation cotton 31 can be replaced, and the insulation cotton 31 can insulate the cooling box 3.

[0055] Principle of the invention:

[0056] The present invention transmits airflow through the main conveying pipe 5 and transmits it to the cooling box 3 through the secondary conveying pipe 6. During the transmission process of the airflow, the cooling mechanism 2 cools the airflow, thereby realizing refrigeration in the cooling box 3, thereby realizing refrigeration of the items in the cooling box 3. When the refrigeration temperature in the cooling box 3 needs to be controlled, the personnel operates the control component 9 and sets the temperature sensed by the temperature sensor 10 on the control component 9. After the temperature setting of the control component 9 is completed, if the cold air in the cooling box 3 is too low or too high, a signal will be transmitted to the control component 9, and the control component 9 controls the solenoid valve 7 to be closed or opened. When the solenoid valve 7 is closed, it mainly prevents the cold air from entering the corresponding cooling box 3, thereby causing the temperature in the cooling box 3 to decrease. When the solenoid valve 7 is opened, it is mainly used to transmit the cold air into the cooling box 3, thereby realizing the temperature reduction in the cooling box 3. When the personnel opens the end cover 4, the sensor 11 senses that the end cover 4 is opened, and transmits a signal to the control component 9 and the control panel. The control panel controls the solenoid valve 28 to be closed to reduce the loss of cooling.

[0057] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
