[0002] For a container freezer, in an in-built container freezer, the freezer can be started at will during transportation to keep the container at a specified temperature; while for an external one, it must rely on the freezers equipped on special container trucks, ships and special yard stations to refrigerate. During the use of the container freezer, a ventilation equipment is needed for ventilation. The ventilator is designed and developed based on the principle that when air is supplied on one side and drawn on the other side in a sealed room, a "fresh air flow field" will be formed in the room. It relies on mechanical air supply and air drawing to force a fresh air flow field to be formed in the system, and it is an electrical appliance that always keeps the air in the enclosed space clean and fresh.

[0003] For the existing ventilation equipment for a container freezer, the sealing measure is to fasten the air duct opening with a simple sealing cover. When ventilating the inside of the container during use, the sealing cover installed on the outside needs to be manually opened, and then the fan can be turned on for ventilation, so the practicability is not good. Therefore, a ventilation equipment for a container freezer needs to be proposed. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-7 , the present invention provides a technical solution: a ventilation device for a container freezer, including an installation frame 1 and an air duct 5. Fixed pieces 2 are fixed on both sides of the installation frame 1, and installation screws 3 penetrate through the front of the fixed pieces 2. An air duct 5 is fixed behind the installation frame 1, and a guardrail 4 is fixed in the front of the inner side of the air duct 5. The guardrail 4 is distributed in a circular pattern in the front of the inner side of the air duct 5. During the use of the device, by setting the guardrail 4, sundries are prevented from being sucked into the air duct 5. A fan 6 is installed inside the air duct 5, and a driving motor 7 is installed below the inner side of the installation frame 1. A linking block 8 is installed at the output end on one side of the driving motor 7, and a transmission chain 9 is sleeved outside the linking block 8. A transmission rod 10 penetrates through the inside of the installation frame 1, and a sealing plate 11 is fixed on the outside of the transmission rod 10. The sealing plate 11 forms a rotating structure with the installation frame 1 through the transmission rod 10, and the sealing plates 11 are distributed in parallel on the inner side of the installation frame 1. During the use of the device, by turning on the switch of the driving motor 7, the linking block 8 and the transmission chain 9 are driven to rotate. The inner side of the transmission chain 9 and the outside of one end of the transmission rod 10 are both serrated, and the transmission rod 10 is meshed with the transmission chain 9. Meshing transmission has the characteristics of a large adaptation range, high transmission efficiency, long working life, smooth transmission, high reliability, ensuring a constant instantaneous transmission ratio, and being able to achieve two-axis transmission with various position requirements. The transmission rod 10 and the moving chain 9 are meshed and also driven to rotate. At this time, the sealing plate 11 starts to rotate, and the switch of the driving motor 7 is turned off until the sealing plate 11 rotates horizontally and is parallel to the ground. This method can replace the design of the sealing cover of the traditional ventilation pipeline. When ventilating, there is no need for staff to manually remove the sealing cover, the operation is simple and convenient, saving the physical strength of the staff and enhancing the practicability of the device;

[0024] Please refer to Figure 1-7, sealing gaskets 12 are attached to both end surfaces of the sealing plate 11. The sealing gaskets 12 are adhesively connected to the sealing plate 11. By providing the sealing gaskets 12, the sealing performance when the sealing plates 11 are buckled with each other is enhanced. A clamping groove 13 is provided on the inner wall of the mounting frame 1, and a limiting frame 14 is mounted on the inner wall of the mounting frame 1. The limiting frame 14 is snap-fitted to the mounting frame 1 through the limiting frame 14. The limiting frame 14 is arranged in a "U" shape. During the use of the device, the limiting frame 14 can be inserted into the inner side of the mounting frame 1 by aligning and inserting the buckle 15 at one end of the limiting frame 14 into the clamping groove 13, so as to limit the transmission chain 9 and prevent the transmission chain 9 from falling off due to long-term operation and vibration during the transportation of the container freezer, effectively reducing the failure rate of the device. A buckle 15 is fixed to one end of the limiting frame 14.

[0025] Working principle: When using the ventilation device for the container freezer, first install the device at the designated position, connect the external power supply, and then during the use of the device, by turning on the switch of the driving motor 7, drive the linkage block 8 and the transmission chain 9 to rotate. The transmission rod 10 meshes with the moving chain 9 and is also driven to rotate. At this time, the sealing plate 11 starts to rotate until the sealing plate 11 rotates horizontally and is parallel to the ground, then turn off the switch of the driving motor 7. This method can replace the design of the sealing cover of the traditional ventilation pipe. During ventilation, there is no need for the staff to manually remove the sealing cover, which is simple and convenient to operate, saves the physical strength of the staff, and enhances the practicability of the device. Through the settings of the clamping groove 13, the limiting frame 14, and the buckle 15, during the use of the device, the limiting frame 14 can be inserted into the inner side of the mounting frame 1 by aligning and inserting the buckle 15 at one end of the limiting frame 14 into the clamping groove 13, so as to limit the transmission chain 9 and prevent the transmission chain 9 from falling off due to long-term operation and vibration during the transportation of the container freezer, effectively reducing the failure rate of the device. When the cold chain is transported to the designated position and it is necessary to ventilate to remove odors and dry the cargo box and the interior before changing the goods, turn on the switch of the fan 6 for ventilation. When the device is not in use, cut off the external power supply of the device. In this way, the use process of the ventilation device for the container freezer is completed.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
