Abstract

The invention discloses a spiral pusher, an energy enhancing rod pushing device and a shock wave generating device. The spiral pusher comprises a movable sleeve and spiral pushing pieces evenly wound on the outer wall of the movable sleeve, and the spiral pushing pieces are perpendicular to the outer wall of the movable sleeve; the spiral pushing piece forms an energy enhancing rod conveying space on the outer wall of the movable sleeve; a push rod through hole for a push rod to pass through is formed in the center of the movable sleeve, an energy converter connecting end is connected with the front end of the movable sleeve, and a reversing mechanism connecting end is connected with the rear end of the movable sleeve; and an energy enhancing rod transfer part is arranged at the front end of the movable sleeve and comprises an energy enhancing rod transfer window formed in the movable sleeve, and the energy enhancing rod transfer window enables the exterior of the movable sleeve to communicate with the push rod through hole. The problems that in the prior art, the reliability of an energy enhancing rod pushing assembly is poor, and the fault rate is high due to the fact that the energy enhancing rod pushing assembly is complex in structure are solved.

Description

technical field [0001] The application belongs to the technical field of shock waves, and in particular relates to a screw propeller, an energy-enhancing rod propulsion device and a shock wave generating device. Background technique [0002] Coal is the conventional energy with the largest reserves and the widest distribution in the world. Coalbed methane is a high-heat, clean and convenient new energy source, which has many advantages such as no pollution and no oil pollution that other energy sources cannot match. Coal bed methane exists in the coal seam in an adsorbed state. In order to realize the industrial exploitation of coal bed methane and speed up the pumping speed of coal bed methane in mines, shock wave generators are often used to transform the coal seam. [0003] The patent "Energy Enhanced Rod Pushing Assembly, Energy Enhanced Rod Pushing Device, and Controllable Shock Wave Generating Device" publication number "CN111379547A" involves an energy enhancing rod ...
