Abstract: A robot for straightening double thin-wall section pipe with undesirably shaped cavities, includes two racks, a positioning component, a shaping component and a driving component. In operation, the double thin-wall section pipe is put in the positioning component, and the shaping component is used for shaping the pipe by the driving of the driving component. The robot improves the working efficiency, and is not only compact in structure design, stable in movement, precise in positioning and reliable in locking, but also convenient for disassembly and maintenance.

Abstract: A connector includes a male connector, a female connector and a rotating clamping structure. The male connector includes a first housing with multiple channels, the female connector includes a second housing with at least one positioning slot. The rotating clamping structure includes a third housing, multiple first positioning pins, multiple stoppers and multiple second positioning pins. The rotating clamping structure can realize the locking or separation of the male connector and the female connector.

Abstract: A nanofriction power generation device with spiral vibrating balls and a buoy body thereof-includes an inner spiral barrel, an outer spiral barrel sleeved outside the inner spiral barrel, hollow balls between the two spiral barrels, an electric energy storage device contained in the inner spiral barrel, and a buoy barrel for containing the outer spiral barrel. The outer wall of the inner spiral barrel and the inner wall of the outer spiral barrel are respectively provided with first spiral tracks and second spiral tracks extending from one end to the opposite other end. The inner spiral barrel is in the outer spiral barrel, and the first spiral tracks and the second spiral tracks have a one-to-one correspondence and form spiral channels. Nanofriction electric generator films are attached to an outer surface of each hollow ball and an inner wall of each spiral channel.
