Description

Background Technology

[0002] When dangerous goods are stored in containers or other similar enclosed spaces, they cannot be opened automatically in case of dangerous situations such as excessively high concentrations of flammable gases, abnormal temperature and humidity, or fire. Manually opening the doors poses a high risk of injury. When the doors are open, toxic and harmful gases are released violently, and there is a large amount of smoke and fire. To prevent the spread to surrounding people and buildings, the doors need to be closed. Manually closing the doors can easily lead to poisoning and burns. Summary of the Invention

Therefore, this application embodiment provides an automatic door opening and locking device to improve the safety of enclosed spaces such as shipping containers. The following detailed description, in conjunction with specific accompanying drawings, illustrates the device.

[0061] Specifically, refer to Figure 1 and Figure 2 The second spur gear at the door hinge is integrated with the door as a whole. When the door rotates, the second spur gear rotates together with the door, and the rotation center of the door coincides with the rotation center of the gear teeth. When the motor is powered on, the first spur gear meshes and drives the door to open or close.

[0062] The first spur gear, meshing with the second spur gear, is driven by a motor to rotate the door. The sensing mechanism includes a combustible gas sensor and a temperature sensor, and its operation is as follows:

[0063] When the door is locked, the sensor detects the accumulation of combustible gas inside the cabinet. First, the electromagnetic lock is de-energized, and then the motor is energized to open the door, thereby releasing the combustible gas and reducing its concentration. This is confirmed by temperature detection to ensure safety.

[0064] When the door is open, the sensor detects the release of toxic and harmful gases. First, the motor is powered on, driving the door to close completely. At this time, the electromagnetic lock is powered on to lock the door, thereby preventing the rapid spread of toxic and harmful gases.
