The invention discloses a fixed-point observation device for water quality in an estuary area. The device comprises a floating body, a water taking tank arranged on the floating body and a water collecting tank arranged on the water taking tank, the water taking tank is limited by a hollow cylinder of which one end is open; a shaft sleeve capable of rotating is arranged at the open end part of thewater taking tank; a plurality of first blades are arranged on the inner wall of the shaft sleeve, a plurality of second blades are arranged on the outer wall of the shaft sleeve, under the conditionthat the first blades are impacted by flowing river water to drive the shaft sleeve to rotate, the second blades can synchronously rotate to generate adsorption force for sucking the river water intothe water taking tank, and the extending direction of the adsorption force is opposite to the gravity direction. After river water mixed with silt enters the water taking tank, the silt can abut against and make contact with the inner wall of the water taking tank based on centrifugal force generated by self-rotation of the water taking tank, and therefore the amount of the silt entering the water collecting tank can be reduced, and finally the purpose of improving the detection accuracy is achieved.

    本发明公开了一种河口区水质定点观测装置,包括:漂浮本体、设置于所述漂浮本体上的取水箱以及设置于所述取水箱上的集水箱,所述取水箱由一端呈开放状的中空圆柱体限定,其中,取水箱的呈开放状的端部上设置有能够自转的轴套,轴套的内壁上设置有若干个第一叶片,轴套的外壁上设置有若干个第二叶片,在第一叶片受流动的河水冲击而带动轴套自转的情况下,第二叶片能够同步转动以产生将河水吸入所述取水箱中的吸附力,吸附力的延伸方向与重力方向相反。当混合有泥沙的河水进入取水箱后,泥沙能够基于取水箱的自转而产生的离心力,进而使得泥沙与取水箱的内壁抵靠接触,从而能够减少进入集水箱中的泥沙的量,最终达到提高检测准确度的目的。
