[0002] There is a large amount of dust in the atmosphere of the port area. The engine room of a tugboat that conducts long-term towing work in the port area must be ventilated to cool the engine room equipment and maintain the equipment's gas supply. However, during this process, a large amount of dust containing ore sand, coal powder, etc. will enter the engine room. On the surface of the engine room equipment, it is extremely easy to cause a reduction in insulation strength, reduce the heat dissipation performance of the equipment, damage the circuit board, cause control system failures or malfunctions, cause electrical equipment to refuse to operate or malfunction, and the long-term accumulation of dust increases the difficulty of cleaning and maintaining the engine room hygiene. Many equipment needs to disassemble the internal devices for dust removal, which has a large workload, low efficiency, affects production and equipment safety, and increases the failure rate.

[0003] In the existing engine room, manual cleaning of the tugboat for each shift and maintenance of the equipment are usually carried out to improve the service life of the equipment and maintain a clean and tidy equipment site. However, after the fan is turned on during tugboat operation, the dust in the air is directly blown into the engine room, and the dust will accumulate again in the engine room, which cannot be avoided at the source. Content of the Utility Model

[0004] The purpose of the utility model is to provide a detachable dust prevention device for a screen window door, which solves the problem that in the background technique, in the existing engine room, manual cleaning of the tugboat for each shift and maintenance of the equipment are usually carried out to improve the service life of the equipment and maintain a clean and tidy equipment site. However, after the fan is turned on during tugboat operation, the dust in the air is directly blown into the engine room, and the dust will accumulate again in the engine room, which cannot be avoided at the source.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A detachable dust prevention device for a screen window door, including a square door and a protection window assembled on one side thereof.
