Description

Mining shutter of airing exhaust convenient to installation is dismantled Technical Field The utility model relates to the technical field of blinds, in particular to a mining exhaust blind window convenient to mount and dismount. Background In the mining process, the ventilation system is one of core facilities for guaranteeing the safety of underground operation, and has the functions of providing a safe working environment for miners by continuously exhausting harmful gas and dust and adjusting temperature and humidity, and the ventilation shutter is taken as an important component of the ventilation system, is usually arranged on a tunnel wall or a ventilation opening, and is used for controlling the direction of air flow and preventing foreign matters from entering an air duct. The existing louver for mine ventilation needs to manually rotate an adjusting knob to adjust when the ventilation quantity is adjusted, is laborious, does not have a further fixing function after blade angle adjustment, and can be unstable after blade adjustment after long-term rotation adjustment. Chinese patent discloses a shutter for mine ventilation (grant bulletin number CN 217872879U) with adjusting function, which patent technology: Through set up the motor in the window frame, when the ventilation volume of regulation shutter is required, namely the inclination of blade, through motor drive lead screw rotation, make movable rod vertical movement, and then can drive the gear rotation with it meshing, thereby drive epaxial blade change angle, and before the adjustment, the pulling handle forward, make the dead lever shift out compression spring from the fixed orifices of slider, when the adjustment, the slider is vertical to slide in the spout, after the adjustment, loosen the handle, the spring drives the dead lever on the handle and inserts in the fixed orifices and fix the slider, thereby can fix the movable rod, make the blade that adjusts be further fixed, avoid long-term rotation regulation, the unsteady phenomenon of blade regulation postregulation can appear. However, the shutter has certain defects that the shutter is the same as a traditional shutter, an operator is required to screw or loosen a large number of fixing bolts one by using tools (such as a spanner) no matter the shutter is first installed or later maintained or detached, the process is tedious, time-consuming and labor-consuming, and the problem of inconvenient installation and detachment is particularly remarkable under the complex, narrow or high-altitude working environment of a mine, so that the labor intensity and the working time of workers are greatly increased, and the maintenance efficiency of a ventilation system is reduced.
