Problems solved by technology
[0002] At present, although the underground damper of coal mines has realized automatic opening and closing, it cannot accurately identify underground workers or mine vehicles. When gravel falls or illegal objects approach in the roadway, the damper will automatically open, making the underground air flow chaotically, forming a wind current A short circuit will affect the normal work of the mine and may cause gas accumulation, which poses a great safety hazard

An underground roadway intelligent air door comprises a front vehicle recognition system, a rear vehicle recognition system, a left door body, a right door body, a front door control system, a rear door control system, a left door opening and closing transmission system, a right door opening and closing transmission system and a master controller. A double-leaf staggering type air door opening andclosing structure, an intelligent recognition technology, an emergency device and the like are adopted in the underground roadway intelligent air door to prevent potential safety hazards caused whenan underground air door is automatically opened due to disturbance. The underground roadway intelligent air door is scientific in principle, compact in structure, high in intelligent degree and capable of achieving that the air door is opened and closed according to the regulation for underground workers or mine cars, accordingly, the ventilation accident is reduced, and the mine safety level is improved.
Description
technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to an intelligent damper for an underground roadway. Background technique [0002] At present, although the underground damper of coal mines has realized automatic opening and closing, it cannot accurately identify underground workers or mine vehicles. When gravel falls or illegal objects approach in the roadway, the damper will automatically open, making the underground air flow chaotically, forming a wind current A short circuit will affect the normal work of the underground, and may cause gas accumulation, which poses a great safety hazard. In addition, a reasonable air door structure can prevent air leakage, ensure sufficient ventilation on the working face, and improve the underground safety level. Therefore, the downhole damper should realize automatic and intelligent opening and closing. Contents of the invention [0003] In order to solve the deficie...
