The invention belongs to the technical field of ocean electromechanical equipment, and discloses a differential coupling type wind and wave complementary power generation system and method and a complementary power generation device. The hydraulic system is used for adjusting and transmitting offshore wind energy and wave energy; a differential planetary gear mechanism is adopted to couple and superpose the output power of the wind energy capturing subsystem and the output power of the wave energy capturing subsystem, and the negative coupling effect in the energy coupling process of the wind energy capturing subsystem and the wave energy capturing subsystem is effectively reduced. Energy is transmitted and adjusted through the hydraulic system, the complexity of the system structure is greatly reduced, and the problem that in most of previous schemes, energy loss is large in the energy transmission and adjustment process is solved. According to the invention, a set of differential planetary ...

TRACK FLAW DETECTION VEHICLE AND PROBE LAYOUT SYSTEM THEREOF

A probe layout system of a track flaw detection vehicle, comprising several single-crystal ultrasonic probes (2), several dual-crystal ultrasonic probes (3), and several phased array ultrasonic probes (4) that have adjustable ultrasonic incident angle functions, all of which are provided on a vehicle body (1) and are used for performing flaw detection on ultrasonic waves emitted from a track surface. Also, each of the single-crystal ultrasonic probes (2), dual-crystal ultrasonic probes (3) and phased array ultrasonic probes (4) may be horizontally rotatably distributed on the vehicle body so as to accommodate different types of tracks. Each probe (2, 3, 4) may adjust in real time the deflection angle thereof according to parameters of a current detection track, which greatly improves the overall ultrasonic coverage area and thereby improves the defect detection rate. At the same time, the phased array ultrasonic probes (4) may directly change ultrasonic incident angles by means of parameter ...
