Unmanned inspection system for gas extraction drilling

Abstract

The utility model discloses an unmanned inspection system for gas extraction drilling. The unmanned inspection system comprises a gas chamber unit, a rotary communication unit, a driving unit, a monitoring analysis unit and a negative-pressure automatic slag and water discharging device, the gas chamber unit forms a gas collection cavity through combination of a drilling cavity and a confluence cavity, a flowing channel for mixed extracted gas after drilling communication is formed, and the rotary communication unit is rotationally arranged on the gas chamber unit and used for isolating the single drilling cavity from the confluence cavity and communicating with the monitoring analysis unit. The arrangement mode that the rotary communication unit is matched with the driving unit is utilized, through simultaneous routing inspection of drill hole groups, the process is simple, the workload is reduced, synchronous operation of automatic routing inspection of single-hole extraction data is facilitated, the operation state of drill hole extraction can be automatically judged through real-time online monitoring of single-hole gas extraction data, and the working efficiency is improved. Once drilling extraction failure is found, a manager is reminded of rescue and maintenance through an early warning signal, extraction negative pressure loss is avoided, and extraction efficiency is improved.
