The application discloses a wide working field linear-rotary multi-port generator based on sea conditions and belongs to the technical field of magnetic gears and generators. The application is composed of a field modulation magnetic screw rod and a controllable multi-port generator. The field modulation magnetic screw rod converts low-speed linear motion of waves into high-speed rotary motion, thereby improving the power density of the direct-drive wave generator. By arranging a power winding and a control winding, the axial flux generator and the magnetic gear magnetic circuit are coupled, the air gap magnetic density is improved, the power density of the generator and the instantaneous power transmission capacity of the magnetic gear are increased, and the maximum power transmission capacity of the axial flux generator is improved through electric excitation, so that the wave range that can be captured in the working area of the device is effectively widened.

The utility model provides a kind of pole piece structure, roll core pole group and cylindrical battery, including pole piece body, pole piece body has coating area, several pole lug areas are arranged at interval along the length direction of pole piece body, at least one pole lug area is equipped with at least 2 pole lug arranged at interval between pole lug area, and pole lug is connected to the long side of pole piece body;Pole piece structure is after participating in winding and forms roll core pole group, and the pole lug area on pole piece structure is arranged at radial in the center hole of roll core pole group towards one end surface of roll core pole group. It improves the space utilization of battery shell, improves the infiltration problem of electrolyte, improves internal resistance and heat dissipation, and improves electrochemical performance.

The application discloses a high-efficiency grinding turntable, relates to the technical field of grinding, and comprises a turntable body, a plurality of placement areas are arranged in the turntable body and are spaced apart along the circumference of the turntable body, a plurality of workpieces are placed side by side in the placement areas of the turntable body, and a pressing assembly is arranged at the end of each placement area of the turntable body, and the pressing assembly presses the plurality of workpieces in the placement areas. The application places the plurality of workpieces side by side in the placement areas, and the pressing assembly presses the plurality of workpieces in the placement areas, so that the adjacent workpieces abut against each other and no gap exists between the adjacent workpieces, the effective working area of the turntable body is increased, the number of workpieces that can be processed in a single grinding cycle is increased, and the grinding processing efficiency of the workpieces is improved.
