The invention discloses a sampling device for water quality detection and a method thereof, and relates to the technical field of sampling, the sampling device comprises a floating block, the bottom of the floating block is provided with a rectangular guide rod, one side of an L-shaped mounting frame is provided with an intermittent extraction piece, and one side, far away from a first positioning ring, of the L-shaped mounting frame is provided with a fixed-distance blocking piece connected with the floating block. According to the water solution sampling device, an intermittent extraction piece and a fixed-distance blocking piece are arranged, a second telescopic air cylinder is started through a controller, when the second telescopic air cylinder stretches, a worm drives a worm gear to rotate by 120 degrees, and in the process, a cam extrudes an extrusion connecting pin through a protrusion, so that a water solution enters a sampling barrel; when the second telescopic air cylinder shrinks, the straight tooth ring rotates relative to the ratchet wheel, so that the cam rotates clockwise by 120 degrees when the second telescopic air cylinder stretches once, and water solutions with different depths can be extracted by matching with the fixed-distance blocking piece, so that the sampling range of equipment is expanded, and the sampling efficiency is improved.
本发明公开了一种用于水质检测的取样装置及其方法,涉及取样技术领域,包括浮块,浮块的底部安装有矩形导杆,L型安装架的一侧设置有间歇抽取件,所述L型安装架远离第一定位环的一侧设置有与浮块相连的定距阻隔件。本发明通过设置间歇抽取件、定距阻隔件,通过控制器启动第二伸缩气缸,当第二伸缩气缸进行伸展时蜗杆带动蜗轮转动一百二十度,在此过程中凸轮通过凸起处对挤压连销进行挤压,以此来使水溶液进入取样筒内,当第二伸缩气缸进行收缩时直齿环便会相对棘轮进行转动,使得第二伸缩气缸进行一次伸缩时凸轮顺时针转动一百二十度,配合着定距阻隔件便可对不同深度的水溶液进行抽取,以此来扩大设备的取样范围,提高了取样效率。
