The invention relates to the technical field of water quality detection sampling devices, and particularly discloses a water sample collection device for sewage detection. A reel is rotatably mounted at one end of the top surface of a floating body, the bottom end of a pipe frame is fixedly connected to the middle of the top surface of the floating body, a rotary valve plate rotatably sleeves the top end of the pipe frame, and a water outlet cylinder rotatably sleeves the top of the rotary valve plate; a paddle driving mechanism is arranged at the bottom of the floating body, the bottom end of a sampling pipe wound on the reel is connected with a heavy hammer type suction port, an input pipe and an output pipe which are connected with a liquid pump are respectively connected with a water inlet cylinder and a water outlet cylinder, and an inner cavity of the water inlet cylinder is communicated with the sampling pipe; an emptying cylinder and a plurality of sample cylinders are sleeved in insertion holes uniformly formed in the top surface of the pipe frame in the circumferential direction, an inner cavity of a water outlet cylinder is communicated with an inner cavity of a rotary valve plate, and the rotary valve plate rotates under the driving action of power, so that water passing holes in the bottom surface of the rotary valve plate are sequentially opposite to the top ends of the emptying cylinder and the sample cylinders; the problem that a water sample collecting device is difficult to efficiently and continuously collect water samples at multiple depths in a water area is solved.
本发明涉及水质检测采样装置技术领域,具体公开了一种污水检测用水样采集装置,卷盘转动安装于浮体顶面一端,管架底端固定连接于浮体顶面中部,旋转配流盘转动套接于管架顶端,出水筒体转动套接于旋转配流盘顶部,浮体底部设有桨叶驱动机构,卷盘上卷绕的采样管的底端连接有重锤式吸口,液体泵连接的输入管和输出管分别与进水筒体出水筒体连接,进水筒体内腔与采样管连通,管架顶面沿周向均匀开设的插孔内套装有一个排空筒体和多个样品筒体,出水筒体内腔与旋转配流盘内腔连通,旋转配流盘在动力驱动作用下转动使得其底面的过水孔依次与排空筒体和样品筒体顶端正对;解决了水样采集装置难以高效、连续地采集水域中多个深度水样的问题。
