The invention relates to the technical field of self-rescue in coal mine wells, and discloses a self-rescue device for drowning prevention in coal mine wells, which comprises a self-rescuer shell, a shoulder strap and a waist strap are respectively arranged on the self-rescuer shell, a life buoy is arranged on the outer surface of the self-rescuer shell, and an oxygen bottle group is detachably mounted in the self-rescuer shell. A cleaning tank is fixedly installed in the self-rescuer shell, a first one-way valve is arranged at the top of the cleaning tank, a valve hole is formed in the first one-way valve, and the top of the first one-way valve fixedly communicates with a breathing air bag. According to the self-rescue device for drowning prevention of the coal mine well, comprehensive optimization of the carbon dioxide absorption process is achieved through the dustproof assembly, the material turning and shifting net push-pull mechanism and the guide limiting mechanism; the absorption efficiency of the carbon dioxide is remarkably improved by increasing the contact area of the carbon dioxide and the carbon dioxide absorbent, reducing the obstruction of a precipitation layer, optimizing the flowing of airflow, reducing the raising of dust and the blockage of meshes and the like.
本发明涉及煤矿井自救技术领域,公开了一种用于煤矿井防溺水的自救装置,包括自救器外壳,所述自救器外壳上分别设置有肩带与腰带,所述自救器外壳的外表面设置有救生圈,所述自救器外壳的内部可拆卸安装有氧气瓶组,所述自救器外壳的内部固定安装有清净罐,所述清净罐的顶部设置有第一单向阀,所述第一单向阀上开设有阀孔,所述第一单向阀的顶部固定连通有呼吸气囊。此用于煤矿井防溺水的自救装置通过防尘组件、翻料拨网推拉机构以及导向限位机构实现了对二氧化碳吸收过程的全面优化,通过增加二氧化碳与二氧化碳吸收剂的接触面积、降低沉淀层阻碍、优化气流流动、减少粉尘上扬与网孔堵塞等措施,显著提高了二氧化碳的吸收效率。
