Abstract

The invention discloses a multifunctional cooling sampling pipe which comprises a drill rod connector, a double-lead cooling sampling pipe integrally inserted with the drill rod connector, and a drill bit fixed at the other end of the double-lead cooling sampling pipe, wherein a connector is arranged at the front end of the drill rod connector; a hollow air guide cooling sampling sleeve pipe extends outwards from the rear end of the connector; a groove concentric with the connector is formed in the front end of the connector; a cooling air channel communicated with the groove is formed in the air guide cooling sampling sleeve pipe; a cooling air outlet communicated with the interior of the air guide cooling sampling sleeve pipe is formed in the outer wall of the air guide cooling sampling sleeve pipe; a cooling air inlet is formed near the outer side of the cooling air outlet; one end of the cooling air inlet is communicated with the side wall of the cooling air channel 2 while the other end of the cooling air inlet is communicated with an air inlet groove of a spiral cooling groove. The multifunctional cooling sampling pipe is simple in structure and easy and convenient to operate, and has the beneficial effects of cooling a spiral pipe wall, preventing sliding and locking, quickly cutting backwards, spirally discharging powder, cleaning the pipe in a hole, automatically switching between drilling and sampling, and avoiding coal sample coking, losing, sample mixing, pipe clamping and the like.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of coal sampling equipment, in particular to a multifunctional cooling sampling pipe. Background technique [0002] Gas accidents are one of the major disasters and safety hazards in coal mines. The occurrence of coal mine gas determines the severity of coal mine gas accidents, and it is one of the basic parameters for gas control work such as coal and gas outburst risk prediction, coal seam gas reserve calculation, and coal seam gas extractability evaluation. The measurement of coal seam gas parameters is the basic way to grasp the coal seam gas situation. Through the measurement of gas parameters, the gas pressure, gas content, related physical properties of coal and some characteristics of coal adsorbed gas can be determined, which is of great significance for formulating prevention and control measures, gas drainage and comprehensive gas management. At present, sampling technology...
