Problems solved by technology
[0004] However, in the process of realizing manual pressure relief, the operator needs to open the pressure relief window outward on the air inlet side of the air door wall, and when the operator is on the air return side of the air door wall, it is difficult to open the air discharge window on the air inlet side. Press the window, so that the purpose of manual pressure relief cannot be achieved

The invention discloses an opening system for pressure relief windows. The opening system for pressure relief windows comprises a pressure relief window (1) arranged at the air inlet side of an air door wall (7), a pipeline (5) extending from the air return side to the air inlet side of the air door wall (7) is arranged above the air door wall (7), one end (close to the air inlet side) of the pipeline (5) is provided with a first fixed pulley (4), the two ends of a rope (3) respectively extend to the air inlet side and air return side of the air door wall (7) through the first fixed pulley (4) and the pipeline (5), and one end of the rope (3) at the air inlet side of the air door wall (7) is connected with a free end below the pressure relief window (1). According to the scheme provided by the invention, when an operator passes through an air door from the air inlet side of the air door wall, after an operation of pressure relief is implemented by opening the pressure relief window at the air inlet side of the air door wall by a handle at the air return side of the air door wall, the operator can open the air door and then passes the air door.
Description
technical field [0001] The invention relates to the technical field of mine ventilation equipment, in particular to a pressure relief window opening system. Background technique [0002] In the prior art, the ventilation of the mine is realized by the air inlet / return tunnel. Usually, there are multiple air doors between the air inlet / return roadways to realize the different air demand of the roadways between different air doors. Because there is a pressure difference on both sides of the damper, if the damper is opened, the air will flow from the side with higher pressure to the side with lower pressure, so the side with higher pressure on the damper is called the air inlet side, and the side with higher pressure The smaller side is called the return air side. It is also because of the pressure difference on both sides of the damper that when the operator opens the damper, he needs to apply a large enough push / pull force to the damper to resist the pressure of the atmosph...
