The invention discloses a device and a method for monitoring high-voltage electric pulse energy and direction with a controllable electrode angle, and belongs to the field of high-voltage electric pulse rock breaking and fracturing. The device comprises a high-voltage power supply, a transmission cable, a capacitor, an output cabinet, a spark gap switch, a computer, a blasting vibration meter, a sealed cavity and a high-voltage electric pulse electrode angle controllable device; the high-voltage electric pulse electrode angle controllable device comprises an electrode head, a rubber base plate, a high-voltage electrode, a grounding electrode, a fixed frame, a rotatable frame and a scale disc; and the high-voltage electric pulse electrode angle controllable device is located in the sealed cavity, and the center of the rotatable frame is located in the center of the sealed cavity. According to the monitoring device, the angle between the electrode and the vertical direction can be changed, and therefore the pulse propagation direction and energy changes at different angles can be obtained, monitoring at any angle of 360 degrees can be achieved through one electrode, and therefore the changes of the angle and pulses are analyzed.

Description

technical field [0001] The invention relates to a device and method for monitoring the energy and direction of high-voltage electric pulses with controllable electrode angles, belonging to the field of high-voltage electric pulse rock breaking and fracturing. Background technique [0002] The breaking of rocks is an inseparable activity in human life. In coal mining, coal bed methane extraction, oil mining and other projects, the crushing of the completed rock mass is conducive to the safe and efficient mining of resources. In today's engineering construction, the amount of rock crushing is increasing, and the crushing efficiency is also required to be continuously improved. More efficient, environmentally friendly, energy-saving and safe methods are constantly pursued in engineering. [0003] In recent years, a number of emerging rock-breaking technologies have emerged: one is mechanical energy crushing of rocks, including ultrasonic waves, high-pressure water jet crushing...
