This utility model discloses a cold storage facility for fresh food preservation, relating to the field of cold storage technology. The cold storage facility includes a refrigerated storage room, with a door rotatably connected to the side of the refrigerated storage room via a pin. An entrance / exit corresponding to the door is located at the end of the refrigerated storage room, and a folding ramp is inclinedly provided at the bottom of the entrance / exit. The folding ramp includes an inclined main plate, and a folding connector is inclinedly provided at the corner of the inclined main plate near the door. A dovetail-shaped groove is provided at the bottom of the door, and an adjustable slider that slidably engages with the folding connector is also provided in the dovetail-shaped groove. This utility model provides a folding ramp and a folding connector that can fold together between the refrigerated storage room and the door. When the door is opened, the folding ramp and folding connector can be tilted at the exit position, facilitating the entry and exit of transport vehicles and preventing the door from automatically closing during cargo handling.

This invention discloses an immersive marine biodiversity experience device in the field of experience equipment technology, comprising: a frame, a seat mounted on the frame, a detector mounted on the seat, a retraction assembly at the top of the frame, a first flexible connector mounted on the retraction assembly, and an experience component at the end of the first flexible connector. The experience component includes VR glasses, audio equipment, and a recognition device. This application achieves automated retraction and deployment of the experience component by setting a human presence detector on the experience device to monitor in real time whether the seat is in use. When a person is detected on the seat, the retraction assembly is controlled to release the first flexible connector, causing the experience component to descend. When the detector detects no one on the seat, the retraction assembly is controlled to retract the first flexible connector, causing the experience component to rise. This significantly reduces the risk of physical damage to the device due to improper human operation and extends its service life.
