Scanning is a basic way of capturing information by utilizing various wave detection, and has extremely wide application in the technical fields of medical equipment, radar detectors, laser scanners and the like. Existing scanning devices are mainly divided into two main scanning modes, namely mechanical scanning and electric scanning. The mechanical scanning is realized by means of mechanical transmission and rotation of a scanning head, and is mainly applied to a multi-face rotating mirror scanner, a galvanometer scanner (galvanometer type), a micro-motor system (MEMS) and a crank rocker mechanism; the electric scanning is a mode of realizing ray deflection through electromagnetic effect, and is mainly based on a voice coil motor, piezoelectric ceramics, electromagnetic deflection and the like. Among the two scanning devices, the former has a smaller achievable scanning range and is not suitable for realizing high-speed uniform scanning; the motor is always in a forward and reverse transfer alternate working state during scanning, and the defects of high failure rate and lower service life exist.

The first gear 1, the third gear 3, the fifth gear 5 and the sixth gear 6 are all incomplete gears, and the first gear 1 and the third gear 3 and the fifth gear 5 and the sixth gear 6 are not meshed at the same time; if the control motor 12 drives the first gear 1 to rotate clockwise: when the first gear 1 is meshed with the third gear 3, the sixth gear 6 and the third gear 3 synchronously rotate anticlockwise; when the fifth gear 5 is meshed with the sixth gear 6, the sixth gear 6 rotates clockwise; when the two states are separated, the three-six duplex gear shaft 8 can rotate back and forth within a certain angle, so that sector scanning of the scanner 10 is realized.
The energy accumulator 9 is a double-torque cylindrical spring, two ends of the energy accumulator are respectively fixed on the third gear 3 and the sixth gear 6, and the other end of the energy accumulator is fixedly arranged on the shell 11. The energy accumulator 9 can absorb or release kinetic energy when the sixth gear 6 rotates clockwise and anticlockwise, so that impact of the gear during steering is effectively reduced, and the service life of the device is prolonged.

A scanning method of a uniform-speed sector scanning device comprises the following specific processes:
the working power supply is turned on, the motor 12 is controlled to start, and the first gear 1 and the second gear 2 are driven to rotate clockwise; at this time, the first gear 1 is meshed with the third gear 3, and the fifth gear 5 and the sixth gear 6 are not meshed;
