[0002] The transfer station is a transshipment point for transporting coal. There is a lot of dust on site and personnel need to clean it regularly. Since the safety exit indicator light is installed 30 cm from the ground, it will be accidentally flushed during the ground flushing process, causing the safety exit indicator light to be frequently damaged, posing a safety hazard, and a protective cover is required to protect the safety exit indicator light.

[0003] In the existing technology, the protective cover for the emergency exit sign is usually covered on the outside of the emergency exit sign by a transparent acrylic plate and then fixed by bolts. In actual use, the device is covered on the outside of the emergency exit sign by a transparent acrylic plate and then fixed by bolts, which increases the tediousness of the staff's work during the later replacement process, resulting in the transparent acrylic plate cannot be replaced quickly, and the overall sealing of the device is poor. During the subsequent cleaning process, dust is easy to enter the interior of the device and cause damage to the device. In the process of long-term use, the outside of the protective cover is easily covered with dust, which easily causes the emergency exit sign to be unclear, thereby causing the loss of the function of the emergency exit sign. Therefore, there is a need to improve a protective cover for emergency exit signs. Utility Model Content
