The invention discloses a multi-mode composite motion robot for cleaning cakes in an ash discharging pipeline of an ash silo, which comprises a head screw mechanism, a middle wriggling mechanism, a tail screw mechanism and a cleaning mechanism, each of the head screw mechanism and the tail screw mechanism comprises a shell, a large bevel gear, a small bevel gear, a reducing motor, a supporting wheel trapezoidal lead screw, a driving wheel trapezoidal lead screw, a bracket, a belt, a polished rod, a supporting wheel, a driving wheel, a supporting wheel connecting piece and a driving wheel connecting piece; the middle creeping mechanism comprises a middle shell, a gear motor, a gear, an upper rack, a lower rack and a guide rail mechanism; the cleaning mechanism is arranged at the front end of the head screw mechanism and comprises a sensor module used for recognizing caking in the ash discharging pipeline and a cleaning device with air injection and rotary cleaning functions. The pipeline cleaning device can be suitable for cleaning pipelines made of various materials, a supporting wheel supporting and driving wheel supporting mode and a spiral advancing, wriggling and spiral wriggling advancing mode can be achieved, and the cleaning efficiency and quality can be effectively improved.

The present invention discloses a marine engineering sliding traction extension device and method, comprising a wire rope extension component and a tool rope extension component connected thereto; one end of the wire rope extension component is connected to the main lug plate on the cargo at the backyard of the dock, and the other end is connected to one end of the tool rope extension component; the other end of the tool rope extension component is connected to the main lug plate on the transport ship; the wire rope extension component comprises a first pulley group, a second pulley group and a traction wire rope which are sequentially connected to the main lug plate on the cargo through a wire rope; the tool rope extension component comprises a plurality of tool ropes sequentially connected to the second pulley group, and the tool rope at the end is connected to a cylinder tensioning device, and the cylinder tensioning device is connected to the main lug plate on the transport ship. The present invention solves the problem of long-distance traction and transportation of large marine engineering products from the backyard of the dock when the large marine engineering products are launched by sliding.

This utility model relates to a brushless motor, and more particularly to a brushless motor that does not require a Hall sensor. It includes a rotor and a stator. The rotor includes a permanent magnet, and the stator includes an electromagnetic assembly. The electromagnetic assembly cooperates with the permanent magnet. The permanent magnet is arranged circumferentially along the rotor's rotation center line, and the electromagnetic assembly is arranged radially along the rotor's rotation center line. The electromagnetic assembly includes electromagnet A and electromagnet B, with at least two of each. Electromagnets A and B are staggered circumferentially along the rotor's rotation center line. Electromagnets A and B have the same magnetic pole facing the rotor. Electromagnets A and B are alternately energized, forming a traction segment between them. As long as the permanent magnet is between the start and end points of the traction segment, it will experience a traction force. When the permanent magnet is at the start or end point of the traction segment, it will remain stationary and will not reverse.
