Aircraft service pit latch

A buried subsurface pit for use beneath a surface across which aircraft travel for servicing aircraft is provided with a pit latching mechanism for holding and releasing a pit lid mounted atop the buried pit. A shallow latch operating lever storage recess is defined in the upper surface of the pit lid. An actuator rod passageway is formed in the pit lid and extends between the latch operating lever storage recess and the undersurface of the pit lid. A catch is located in alignment with the actuator rod passageway at the undersurface of the pit lid. The catch is mounted for rotation about a horizontal axis of catch rotation. An actuator rod is disposed for longitudinal, reciprocal movement in the actuator rod passageway. A latch operating lever has opposing latch handle and actuator rod engaging ends. The latch operating lever is mounted between its opposing ends to the pit lid proximate the upper surface of the pit lid for rotation on a fulcrum about a horizontal latch operating lever axis of rotation which is located just below the upper surface of the pit lid. The latch operating lever is movable between a stored position in the latch operating lever storage recess and an actuator rod engaging position in which the latch handle end of the latch operating lever is raised out of the latch operating lever storage recess so that the actuator rod operating end of the lever depresses the actuator rod to disengage the catch.

Unmanned aerial vehicle routing inspection base station

The invention discloses an unmanned aerial vehicle routing inspection base station. The base station comprises a supporting frame, a charging base, a solar cell panel, a protective apparatus and an ultrasonic distance-measuring module. The charging base serves as a unmanned aerial vehicle landing platform and is provided with two stages of charging electrodes that are in contact with two charging interfaces designed in an unmanned aerial vehicle in a matched way to charge the unmanned aerial vehicle; the protective apparatus is mounted on the charging base; the interior of the protective apparatus serves as a parking space for the unmanned aerial vehicle; the two stages of charging electrodes are positioned in the protective apparatus; the top surface of the protective apparatus adopts an openable structure; the solar cell panel is used for supplying power to the unmanned aerial vehicle and the protective apparatus; and the ultrasonic distance-measuring module is mounted in the internal wall surface of the protective apparatus and used for measuring the distance between the unmanned aerial vehicle and the charging base. The unmanned aerial vehicle routing inspection base station has the advantages that the unmanned aerial vehicle can be automatically charged, so that long-distance routing inspection of the unmanned aerial vehicle is realized; and in addition, the protective apparatus is designed, so that the charging base can be protected, and the influence of weather on the unmanned aerial vehicle routing inspection base station can be greatly reduced.
