The invention relates to a
water sample collecting device for
environmental design of an ancient village. The
water sample collecting device comprises a gasbag type floating object connected to a sampling
assembly through an adjusting mechanism, an outer shell for carrying the adjusting mechanism and the sampling
assembly and in a sealed state and the adjusting mechanism. The adjusting mechanism includes a second motor, a second threaded sleeve and a second
threaded rod, one end of the second threaded sleeve is fixedly connected to an output shaft of the second motor through a
coupling, and the other end of the second
threaded rod extends into a lifting cavity formed in the outer shell and is connected with the second
threaded rod in a threaded mode. The upper end of the second threaded rod penetrates through the upper wall of the lifting cavity which is slidably connected with the upper end of the second threaded rod and is fixed to the gasbag type floating object. The
water sample collecting device is novel in design,
underwater positioning of the sampling
assembly is performed by the gasbag type floating object, and the arranged adjusting mechanism can adjust the
underwater penetration of the sampling assembly, so that
water collection required at different depths is realized, the use is convenient, no excessive mechanical bracket supporting is required, and the structure issimple.
