Abstract

The invention discloses an air duct protection device convenient to disassemble and assemble and used for coal mine gas ventilation, and relates to the technical field of air duct protection. According to the technical scheme, the protective device comprises a protective cylinder, the protective cylinder comprises a plurality of first protective plates and a plurality of second protective plates, the first protective plates and the second protective plates are alternately matched to form the protective cylinder, the two sides of the first protective plates in the length direction are fixedly connected with first butt joint plates, and the sides, away from each other, of the two first butt joint plates are fixedly connected with a plurality of pins; second butt joint plates are fixedly connected to the two sides of the second protection plate in the length direction, a pin connecting window is formed in one side of each second butt joint plate and comprises an inserting end and a locking end, an inserting opening is formed in the position, above the inserting end, of the first protection plate, and the connecting position of the first protection plate and the second protection plate is fixed through a limiting assembly. The inner side of the first protection plate is connected with a fixing mechanism. The device has the advantages of being low in maintenance cost, convenient to disassemble and assemble, convenient to repair and maintain, small in occupied space and convenient to store.

Description

technical field [0001] The invention relates to the technical field of blower protection, in particular to a blower protection device for coal mine gas ventilation which is easy to assemble and disassemble. Background technique [0002] As a common air guide device, the air duct can guide the air flow along the pipeline. During coal mining, the air duct is used to ventilate the mine with a local fan to ensure a safe working environment underground. Due to the twists and turns of the roadway in the coal mine Therefore, the air ducts in coal mines mostly adopt flexible structures to meet the needs of roadways. In the process of coal mine excavation, it is often accompanied by falling rocks and flying stones. There is a risk of hitting the air duct, which will easily cause the air duct to break and reduce the ventilation effect in the mine. [0003] For example, the Chinese patent with the existing publication number CN213420297U discloses a blower protection device for coal m...
