The invention discloses a magnetic wheel type wall climbing robot with curved face self-adaptation adsorption. The magnetic wheel type wall climbing robot with the curved face self-adaptation adsorption comprises a mobile platform with the curved face self-adaptation adsorption, an acceleration sensor, a wireless communication module, a camera and an upper computer, wherein the mobile platform with the curved face self-adaptation adsorption consists of magnetic driving wheel units and curved face self-adaptation frames; and through the common deformation of an elastic permanent magnetic adsorption layer in each magnetic driving wheel and a loose-leaf hinge in each frame, the curved face self-adaptation adsorption is realized. The magnetic wheel type wall climbing robot with the curved face self-adaptation adsorption provided by the invention has a good curved face self-adaptation ability and a good obstacle climbing ability and can stably walk on a curved face with smaller curvature radius, thereby availably meeting the demands of engineering applications such as wireless health detection of a large-span space grid structure and the like.

The invention provides a multi-stage capillary pump, which comprises a first-stage porous structure taken as a condenser, a second-stage porous structure taken as a capillary channel and a third-stage porous structure taken as an evaporator, wherein the three stages of porous structures are connected into a whole; capillary apertures of the porous capillary structures are different from each other, the first-stage porous structure has the largest capillary aperture, the second-stage porous structure has the capillary aperture smaller than that of the first-stage porous structure, and the third-stage porous structure has the smallest capillary aperture; and an outlet end of the third-stage porous structure of the evaporator is provided with an concave outlet. The multi-stage capillary pumpcan ensure the full circulation of an alkaline metal working fluid in an alkaline metal thermoelectric direct converter, avoid the flow breaking of the alkaline metal working fluid formed by the alkaline metal thermoelectric direct converter during high load, and avoid the dry burning produced in the capillary pump.

The invention relates to a motion adsorption unit of a wall-climbing robot; two groups of motion absorption mechanisms are symmetrically arranged on a frame, so that the two driving wheels (1) of each group of motion absorption mechanism are respectively arranged on the outer side of a shaft support (46) on one side of the frame; a moving cam (4) which is formed by the fitting of matched surfaces(36) is arranged on a moving cam support (47) on one side of the frame, so that the active wheel of the driving wheel (1) is on one end of the moving cam which is close to a stop section (38), and the circular arc of the stop section (38) and the active wheel are concentric; and the circular arcs on both ends of the outline of a cam piece and the active wheel and the passive wheel of the driving wheel (1) are concentric respectively. The motion adsorption unit of the wall-climbing robot uses the motion track of the moving cam (4) so that a vacuum sucker is easy and feasible in absorbing and leaving the wall surface, thereby not only realizing the flexible movement of the robot but also ensuring that all sucker components in the movement process can keep enough adsorbability, and is characterized by simple structure, convenient operation, easy control and high reliability.

The invention discloses an airplane steering surface deflection angle measurement device comprising first and second connecting rods, and first, second and third angle measurement devices. The first ends of the first and second connecting rods are detachably and pivotally connected with an airplane rotating wing surface fixed side and an airplane steering surface respectively in use. The second ends of the first and second connecting rods are pivotally connected with each other and are away from the airplane rotating wing surface in use. The first, second and third angle measurement devices are respectively arranged at the first end of the first connecting rod, the first end of the second connecting rod and the second end of the first connecting rod so as to respectively detect the angles of a first inclined angle formed by the first connecting rod and the airplane rotating wing surface fixed side, a second inclined angle formed by the second connecting rod and the airplane steering surface and the first inclined angle formed by the first connecting rod and the second connecting rod. The invention also discloses an airplane steering surface deflection angle measurement method. The steering surface rotating angles of all angle wing potions within range from a horizontal steering surface to a vertical steering surface can be measured.
