Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coal mine drainage, especially a self-walking anti-explosion hydraulic drainage device. BACKGROUND

[0002] In the process of coal mining, water inrush is one of the factors that seriously threaten the safety of mines. When water inrush occurs, not only is it necessary to quickly drain water to restore the production environment, but also it is necessary to monitor the concentration of toxic and harmful gases in the underground air at all times to protect the life safety of operating personnel. Once water inrush occurs in a coal mine, the consequences are often very serious. Water inrush can lead to deterioration of the working environment inside the mine, a decrease in oxygen content, and an increase in the concentration of toxic gases, which poses a serious threat to the life safety of miners. At the same time, water inrush can also damage the support structure of the mine, leading to mine collapse and further exacerbating the harm of the accident. Therefore, great importance must be attached to the prevention and response to coal mine water inrush accidents to ensure the safety and stability of coal mine production. Once a water inrush accident occurs, emergency drainage disposal is needed to transfer the accumulated water to a safe area such as an inland river. The drainage devices currently used mostly use electric pumps. The cables connected to the electric pumps can have a risk of electric shock due to wear and tear or aging, posing a threat to the life safety of drainage rescue personnel. Using a hydraulic drainage pump to drain water avoids the risk of electric shock, but many hydraulic drainage pumps do not have an anti-explosion design and can cause explosions when used in mines, causing danger, and the drainage pump is relatively large in size and is not convenient to carry to the mine for use.
