Description

Technical Field

[0001] The present invention belongs to the technical field of cold chain logistics, and in particular relates to a three-dimensional storage device for cold chain logistics and a storage method thereof. Background Art

[0002] With the rapid development of the cold chain logistics industry, the requirements for storage equipment are getting higher and higher. Traditional cold chain logistics storage devices have many problems, which limit their application in modern cold chain logistics.

[0003] However, the existing cold chain logistics three-dimensional storage devices have the following disadvantages in actual use: 1. In the existing cold chain logistics storage devices, the layout of the cold air pipes is usually fixed, resulting in uneven distribution of cold air in the cooling room. This uneven cold air distribution will affect the refrigeration effect of the goods, especially for some perishable goods with strict temperature requirements, which may cause partial deterioration or damage of the goods;

[0004] 2. In cold chain logistics warehousing, the monitoring of temperature, humidity and gas composition is crucial. However, traditional warehousing devices often lack real-time monitoring and alarm functions for these environmental parameters. Once the environmental conditions exceed the set range, the goods may be irreversibly damaged, and the staff may not be able to discover and take measures in time;

[0005] 3. The existing storage shelves have a fixed height and cannot be flexibly adjusted according to the height of the goods. This not only leads to low shelf space utilization, but also increases the difficulty of storing and retrieving goods. In addition, traditional shelves cannot adapt to goods of different heights and require frequent adjustment or replacement of shelves, which increases storage costs.

[0006] Therefore, it is urgent to design a cold chain logistics three-dimensional storage device to solve the above problems. Summary of the invention

[0017] Furthermore, the shelf lifting mechanism also includes a slider and a slide groove. The slider is arranged at the lower end of the side of the lifting column, and the inner wall of the column is provided with a slide groove corresponding to the slider.

[0018] Furthermore, a storage method of a cold chain logistics three-dimensional storage device comprises the following steps:

[0019] S1: Turn on the air conditioner, which outputs cold air through the air conditioner pipe body and controls the output of cold air through the solenoid valve, so that the cold air is finally ejected through the cold air nozzle. Then turn on motor 1, which drives reciprocating screw 1 to rotate through the output end. When reciprocating screw 1 rotates, it drives gear 1 inside the installation box to rotate. The rotation of gear 1 drives the synchronous belt to rotate. The rotation of the synchronous belt drives gear 2 to rotate. The rotation of gear 2 drives reciprocating screw 2 to rotate synchronously with reciprocating screw 1. The rotation of reciprocating screw 1 and reciprocating screw 2 drives the slide to slide. The sliding of the slide can drive the cold air nozzle to move left and right. Turn on motor 2, which drives the rotating shaft to rotate through the output end. The rotation of the rotating shaft can drive the cold air nozzle to adjust the angle;

[0020] S2: Monitor the temperature in the cold air room through the temperature sensor, and set the temperature threshold in the cold air room through the controller. When the temperature sensor detects that the temperature in the cold air room exceeds the temperature threshold set by the controller, the controller receives the signal from the temperature sensor and controls the temperature alarm light to flash through the relay to alarm. Monitor the humidity in the cold air room through the humidity sensor, and set the humidity threshold in the cold air room through the controller. When the humidity sensor detects that the humidity in the cold air room exceeds the humidity threshold set by the controller, the controller receives the signal from the humidity sensor and controls the humidity alarm light to flash through the relay to alarm. Monitor the cold air room through the smoke sensor, and when the line in the cold air room fails and produces smoke, the controller receives the signal from the smoke sensor and controls the smoke alarm light to flash through the relay to alarm;

[0021] S3: Turn on the motor 3 on the upper end of the L-shaped fixed plate. The motor 3 drives the rotating rod to rotate through the output end. The rotating rod drives the bevel gear 1 to rotate. The bevel gear 1 drives the bevel gear 2 to rotate. The bevel gear 2 drives the screw to rotate. The screw drives the lifting column to move up and down, thereby achieving the height adjustment of the shelf. When the lifting column moves up and down, it will drive the slider to slide inside the slide slot, thereby improving the stability of the lifting column during the lifting process. When the support frame 2 moves up and down, it will drive the inner rod to slide inside the outer rod, thereby improving the stability of the lifting frame 2 during the lifting process.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention is provided with a mechanism for moving the cold air pipe left and right. The cold air nozzle can move left and right along the reciprocating screw rod 1 and the reciprocating screw rod 2 under the drive of the motor 1. At the same time, with the angle adjustment structure, the spray angle of the cold air nozzle can be flexibly adjusted. This allows the cold air to be evenly distributed throughout the cooling room, effectively solving the problem of uneven cold air distribution caused by the traditional fixed cold air pipe layout. For some perishable goods with strict temperature requirements, it can ensure that they are cooled evenly during the refrigeration process to avoid local deterioration or damage, thereby significantly improving the refrigeration effect and preservation quality of the goods, extending the storage period of the goods, reducing the loss in the cold chain logistics process, and bringing significant economic benefits to cold chain logistics companies.

[0024] 2. The present invention is provided with a monitoring and alarm mechanism, which integrates a variety of monitoring equipment such as temperature sensors, humidity sensors and smoke sensors, and realizes real-time monitoring and alarm functions of environmental parameters in the cooling room through controllers and relays. When the temperature, humidity or smoke concentration exceeds the set threshold, the corresponding alarm light will flash and alarm, and promptly remind the staff to take measures. This not only effectively avoids the risk of damage to goods due to abnormal environmental conditions and ensures the storage safety of goods, but also improves the level of intelligent warehouse management and reduces the workload and cost of manual inspections. At the same time, through real-time monitoring and early warning, potential safety hazards, such as line failures, can be quickly discovered, which helps to eliminate faults in a timely manner, ensure the stable operation of cold chain logistics warehousing equipment, and enhance the reliability and safety of the entire warehousing system.

[0025] 3. The present invention is provided with a shelf lifting mechanism, and the design of the shelf lifting mechanism allows the height of the shelf to be flexibly adjusted according to the height of the goods. Motor 3 drives the screw to rotate, driving the lifting column to move up and down, thereby realizing the height adjustment of the support frame 2. At the same time, the sliding of the slider in the slide groove and the sliding of the inner rod in the outer rod further improve the stability of the lifting process. This design overcomes the limitations of traditional fixed-height shelves, and can reasonably utilize storage space according to the size and storage requirements of different goods, improve space utilization, and reduce storage costs. In addition, the flexible shelf height adjustment function also facilitates the storage and retrieval of goods, improves the efficiency of warehousing operations, reduces the manpower and time costs in the process of loading and unloading goods, and provides strong support for the efficient operation of cold chain logistics warehousing.
