Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature circulating fans, in particular to an emergency protection mechanism for high-temperature circulating fans. Background Art

[0002] A high-temperature circulating fan emergency protection mechanism is a protective device installed in a high-temperature circulating fan system. It is designed to automatically stop operation in the event of a fan failure or abnormality, preventing damage to the entire system or potential safety hazards. This mechanism typically includes functions such as overload protection, overheating protection, and short-circuit protection. By monitoring the fan's operating status and environmental parameters, it can promptly identify problems and implement appropriate protective measures to ensure the safe and stable operation of the high-temperature circulating fan system.

[0003] Some existing emergency protection mechanisms for high-temperature circulating fans usually cut off the power supply to the device when in use. Therefore, when an open fire occurs in the device, the device needs the help of workers to handle it. Because workers need to go through multiple steps in the process of fire extinguishing, it takes a lot of time and causes the best time to extinguish the fire to be missed. Therefore, this problem needs to be solved. Utility Model Content

The first motor can be protected by the setting of the carbon dioxide bin.

[0007] As a further solution of the present invention, the starting mechanism includes two sealing cylinders, both of which are rotatably connected to one side of the carbon dioxide warehouse, and both of the sealing cylinders are rotatably connected to the first synchronous wheel on the surface away from the carbon dioxide warehouse. Both of the first synchronous wheels are sleeved with a screw rod on one side, and both of the screw rods are fixedly connected to the same push plate on the surface close to the carbon dioxide warehouse. The push plate is slidably connected to the inside of the carbon dioxide warehouse, and both of the first synchronous wheels are provided with an adjustment mechanism for adjusting the screw rod on the surface.
