Embodiment
[0032] refer to Figure 1 to Figure 7 , the present embodiment provides a damper control system for a mine, comprising a damper 1, one side of the damper 1 is hinged on the damper frame, the damper 1 is provided with a ventilation hole 2, and the damper 1 is vertically slid to be provided with a valve capable of closing and opening ventilation. The door and window 3 of the hole 2, the windward side of the damper 1 is hung with the door opening counterweight 5 through the sling 4, the gravity of the door opening counterweight 5 is less than the thrust of the wind on the damper 1 when the ventilation hole 2 is closed, and greater than the ventilation hole 2 When the damper 1 is thrust by the wind when it is opened, the other end of the suspension rope 4 goes around the first pulley 6 and is fixed on the damper 1, and the other end of the suspension rope 4 is fixed on the damper on the other side opposite to the hinged side of the damper 1. 1, the windward side of the air door 1 ...

The invention provides an air door control system used for a mine and an application method thereof. The system comprises an air door, one side of the air door is hinged to an air door frame, a vent hole is formed in the air door, a door-window through which the vent hole can be closed and opened is slidably arranged on the air door in the vertical direction, a door-opening balancing weight is suspended at the upwind side of the air door through a lifting rope, the pressure to which the door-opening balancing weight is subjected is smaller than wind push force to which the air door is subjected when the vent hole is closed and larger than wind push force to which the air door is subjected when the vent hole is open, the other end of the lifting rope bypasses a fist pulley and is fixed to the air door, and a door-window driving mechanism is further arranged at the upwind side of the air door. The air door control system aims to solve the problems that it is greatly difficult to open existing air doors in case air cylinders or power pipelines of the air doors have problems, disastrous consequences may be caused if a mine accident occurs or quick evacuation is required, and heavy potential safety hazards exist. The invention belongs to the technical field of mine ventilation.
Description
technical field [0001] The invention relates to a mine damper control system and a control method, belonging to the field of damper design. Background technique [0002] The main function of the damper in the coal mine underground roadway is to block the wind flow and ensure the normal operation of the ventilation system. This causes a large wind pressure difference on both sides of the damper, making it difficult to open the damper; when a person passes through the damper, a force of more than 90Kg is required to open the damper, which is extremely inconvenient to operate. This also brings hidden dangers to safety, not only from the impact force of more than 90Kg when the damper is closed, but also whether the personnel can quickly and safely evacuate when a disaster occurs underground, all require a reasonable redesign of the damper. [0003] At present, some technicians have realized the easy and convenient opening of the damper by using a cylinder and a connecting rod m...
