Abstract
A high-power microwave borehole fracturing device for an engineering rock mass includes a high-power microwave generator, a high-power microwave coaxial heater, a high-power low-loss microwave coaxial transmission line, and a microwave power adaptive regulation and control system. The high-power microwave generator includes a continuous wave magnetron, a permanent magnet, a waveguide excitation chamber, a coaxial circulator, a coaxial matching load, a coaxial coupling converter, a waveguide coaxial converter, and an output waveguide. The high-power microwave coaxial heater includes a microwave transmission inner conductor, a microwave transmission outer conductor, a microwave input connector, a microwave short circuit cap, and a conductor supporting cylinder. The high-power low-loss microwave coaxial transmission line includes an input end coaxial line, middle section coaxial lines, and an output end coaxial line. The microwave power adaptive regulation and control system includes an impedance matching regulator, a microwave power controller, and a temperature sensor.
