Abstract: Disclosed are a telescopic pulse ash blower capable of blowing ash at multiple angles and an ash blowing method. The telescopic pulse ash blower includes a fixed inner core tube, a traveling device, a multipoint rotating mechanism, an outer nozzle tube, a combined propelling device, a base, and a nozzle. The combined propelling device is mounted at one end of the base. The fixed inner core tube is arranged above the combined propelling device. The outer nozzle tube is sleeved on an outer side of the fixed inner core tube. The outer nozzle tube is connected to the traveling device. The traveling device is connected to the combined propelling device. The multipoint rotating mechanism is arranged on an outer side of the outer nozzle tube, the nozzle is connected to the outer nozzle tube. A gas mixer inlet is formed at a top of the fixed inner core tube.

Abstract: A device and a method for laser-inducing cavitation strengthening with multi-system automatic coordination work. The device comprises a plurality of systems, including a clamping system, a lifting system, an imaging system, a computer control system, a laser system and an energy density amplifying system, etc. The device for laser-inducing cavitation strengthening comprises a laser cavitation device and a fixing platform. A water channel is formed in the fixing platform. A cushion block is equipped in the water channel. The wall of the water channel is provided with a temperature sensor. The temperature sensor is connected with a computer. The fixed platform is arranged on a lifting device. The lifting device is located on a two-axis coupling platform. The laser emitted by the laser cavitation device passes through the sidewall of the water channel to be focused in the water channel. The laser cavitation device is connected with the computer.
