Underwater laser ranging device and underwater work apparatus

Abstract

The application discloses an underwater laser ranging device and underwater operation equipment, and relates to the technical field of laser radar. The underwater laser ranging device comprises a waterproof cover, a laser transceiver assembly and a driving assembly. The waterproof cover is used for forming a sealed cavity. The laser transceiver assembly is arranged in the waterproof cover. The driving assembly is used for driving the laser transceiver assembly to rotate. The receiver and the transmitter of the laser transceiver assembly are arranged in the extension direction of the rotation axis of the laser transceiver assembly. Since the receiver and the transmitter are arranged in the extension direction of the rotation axis of the laser transceiver assembly, the two optical axes originally parallel in the waterproof cover can still be kept parallel after entering the water, that is, the optical axis of the receiver and the optical axis of the transmitter are matched. Therefore, the underwater laser ranging device provided by the application can alleviate the problem that the optical axis of the receiver and the optical axis of the transmitter are not matched due to refraction, and ensure high detection accuracy.
