Description

Technical Field

[0001] The utility model belongs to the technical field of ventilators, and particularly relates to a non-stop observation window for a ventilator. Background Technique

[0002] Ventilators are widely used for ventilation, dust removal and cooling in factories, mines, tunnels and buildings, ventilation and induced draft of boilers and industrial furnaces, etc. Ventilators mainly drive the operation through impellers. When there is abnormal noise or some small problems and it is necessary to observe the internal situation, previously a hole door was opened on the fan. This hole door can be used for observation or people can get into the fan for maintenance, but it requires the machine to be shut down. The running equipment does not have the condition of shutting down for inspection. However, to ensure the safe operation of the entire equipment, maintenance needs to be carried out after shutting down. When maintaining, the cover plate installed on the casing needs to be removed as a whole to observe the internal situation, and the cover plate is relatively heavy. After removal, hoisting equipment is required for cooperation, which will increase unnecessary maintenance work and is time-consuming and laborious. Therefore, there is an urgent need for a non-stop observation window for a ventilator that can be observed without shutting down the machine. Content of the Utility Model

[0005] The square tube part and the flange connecting part are fixedly connected. One end of the flange connecting part away from the square tube part is attached to the transparent observation plate.
