Abstract
The present invention discloses a damage detection apparatus for a lock gate sill, including a support, a water storage tank, a water inlet barrel, a filter device, a water pump, and a control device, wherein a barrier is vertically disposed at the bottom of the water storage tank, multiple water discharge pipes are vertically disposed in the barrier, upper ends of the water discharge pipes are communicated with the water storage tank, the water discharge pipes have different heights, lower ports of the water discharge pipes together compose a truncated conical cavity, a camera is disposed at the bottom of the water storage tank in a sealed manner, and a lens of the camera is located in an upper part of the truncated conical cavity. When it is desired to perform damage detection for the lock gate sill, muddy water is filtered by the filter device into clear water, and the clear water is pressurized by the water pump and then discharged from the water discharge pipes, such that the muddy water in the barrier is continuously diluted by clear water, the camera is in a shooting environment of clear water, and the lock gate sill is shot for detection at this time, whereby it is ensured …
