Title:
ENGINEERING ROCK MASS HIGH-POWER MICROWAVE IN-HOLE CRACKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/213989
Kind Code:
A1
Abstract:
An engineering rock mass high-power microwave in-hole cracking device, comprising a high-power microwave generator, a high-power microwave coaxial heater, high-power low-loss microwave coaxial transmission lines, and a microwave power adaptive control system. The high-power microwave generator comprises a continuous wave magnetron, a permanent magnet, a waveguide excitation cavity, 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 comprises a transmission line inner conductor, a transmission line outer conductor, a microwave input connector, a microwave short-circuit cover, and a conductor support tube; the high-power low-loss microwave coaxial transmission lines comprise input end coaxial lines, middle-section coaxial lines, and output end coaxial lines, and the input end coaxial lines are connected to the output end coaxial lines by means of several series-connected middle-section coaxial lines; the microwave power adaptive control system comprises an impedance matching regulator, a microwave power controller, and a temperature sensor, and impedance real-time matching is performed on microwave power by means of the impedance matching regulator.
