Further, in this embodiment, the depth recognition device 100 for unmanned aerial vehicle further includes a cover plate 61 and an elastic reset member 62, wherein the mounting end of the cover plate 61 is rotatably mounted on the upper end of the seat body 1 to have a closed state covering the mounting hole 12 and an open state opening the mounting hole 12; the elastic reset piece 62 is disposed at the mounting end of the cover plate 61, and is used for resetting the cover plate 61 from the open state to the closed state. The cover plate 61 is preferably made of a light material, and the cover plate 61 has a large size without being excessively large so as to just cover the position of the mounting hole 12. In practical application, when the lifting plate 2 does not extend out of the mounting hole 12, under the action of the elastic resetting piece 62, the cover plate 61 is covered at the mounting hole 12, which is helpful for preventing water accumulation or ash floating impurities from entering the accommodating cavity 11; when the lifting plate 2 is lifted to the mounting hole 12, the lifting plate 2 has an upward pushing force on the cover plate 61, so that the cover plate 61 is forced to be turned from the closed state to the open state, and the lifting plate 2 is extended out of the mounting hole 12 and exposed. Further, a containing groove may be concavely disposed at a position corresponding to the cover plate 61 on the top of the seat body 1, and the containing groove is adapted to the cover plate 61 and is used for containing the cover plate 61, so that when the cover plate 61 is in the closed state, the upper end surface of the cover plate 61 is flush with the upper end surface of the seat body 1.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
