Abstract: A robot for pond desilting is provided, which includes a frame, a lead screw sliding table, and a suction pipe. An end of the frame is provided with a pressure-resistant cabin. A lead screw base is disposed on the lead screw sliding table. A rotary lead screw is disposed on the lead screw sliding table. The lead screw base is disposed on the rotary lead screw. Waterproof motors are disposed above the lead screw base, a pump body is disposed in the frame, and the suction pipe is disposed at an end of the pump body. When the robot is placed at the bottom of the pond, the motor inside the pressure-resistant cabin drives the power wheels to rotate, the power wheels drive the tracks to rotate around the power wheels, bearing wheels, and tension wheels, thereby driving the frame to move.

Abstract: A coal-fired power generation system and a supercritical CO2 cycle system thereof are provided. The supercritical CO2 cycle system includes a compressor unit and a turbine unit. The turbine unit includes a preceding stage heater, a preceding stage turbine, a last stage heater and a last stage turbine successively connected in series. An exhaust port of at least one of compressors in the compressor unit is in communication with the turbine unit through a split flow pipe, and a communication position between the split flow pipe and the turbine unit is located downstream of a suction port of the preceding stage turbine. An auxiliary regenerator and an auxiliary heater are provided at the split flow pipe, and the auxiliary regenerator is located upstream of the auxiliary heater.

Abstract: The invention provides a method and system for upgrading Normal Disk Controller to RAID (Redundant Array of Independent Disks) Controller. Unlike Normal Disk Controller that reports the exact physical disks to Host Computer System, the RAID Controller only reports the configured RAID Logical Units. According to different RAID configurations, the RAID Controller might increase data availability and storage capacity, improve system performance and flexibility, and realize data protection and recovery. The disclosed method and system for upgrading includes three parts: RAID BIOS (Basic Input/Output System) Initialization and Configuration, OS (Operate System) Driver, and Application Program, and the Controller after upgrading will behave exactly like a RAID Controller, at BIOS level, OS level, and Application level.
