Patent ID: 10400567

Abstract:
The invention discloses a pipeline descaling and rock stratum fracturing device based on electro-hydraulic pulse shock waves, comprising a ground low-voltage control device, a transmission cable and an electro-hydraulic pulse shock wave transmitter. The invention generates available high-strength shock waves with repetition frequency to bombard a specific position of the pipeline or rock stratum so as to achieve the effect of pipeline descaling and rock stratum fracturing; the breakdown field strength of the liquid gap can be effectively reduced to improve the conversion efficiency of the electrical energy to the mechanical energy of the electro-hydraulic pulse shock wave so as to obtain a high-strength electro-hydraulic pulse shock wave; the transmitting cavity adopts a parabolic focusing cavity, and through refraction and reflection of the rotating parabolic cavity, the shock wave is focused in a preset direction and radiates outwards to act on the pipeline dirt or rock stratum while ensuring that the shock wave has no longitudinal component and does not will not damage the liquid within the pipeline and the pipeline sheath, so that the effect of pipeline descaling or rock stratum fracturing is improved after focusing. The invention has the advantages of effectively removing the pipeline dirt, fracturing the rock stratum and improving the permeability as well as high reliability, environmental friendliness and low cost.
