[0002] At present, the fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. When the fan is installed on the equipment after leaving the factory, if it fails to meet the actual process standards during operation, it will easily affect the production of subsequent equipment;

[0003] Prior art, such as the patent application with application number "CN202111289567.1" and name "A method for safety detection and inspection of a ventilator system", includes installing photoelectric sensors, installing wind speed sensors, installing vibration sensors and detecting the operating performance of the ventilator body. When the ventilator is inspected by a vibration sensor, the vibration sensor needs to be fixed on the ventilator. After inspecting one ventilator, the vibration sensor needs to be installed on another ventilator. For this purpose, staff need to frequently disassemble and assemble the vibration sensor. However, the existing vibration sensor installation and removal are relatively troublesome, and require manual tightening and loosening of a large number of screws and bolts, so the efficiency is low, affecting the safety detection efficiency of the ventilator.

[0004] Therefore, we designed a ventilator safety detection device. Utility Model Content

[0019] The beneficial effects of the utility model are:

[0020] 1. The utility model fixes the vibration sensor on a fixing frame, and the fixing frame is installed on the ventilator body through a first connecting component and a second connecting component. The ventilator body transmits vibration to the vibration sensor through the fixing frame, thereby realizing detection of the ventilator body by the vibration sensor.
