The invention provides a water body sampling device. The water body sampling device comprises a reel, a throwing line, a counterweight, a water pumping device, a floating body and a water taking device, one end of the throwing line is wound on the reel, and the other end of the throwing line is fixed on the floating body; the bottom end of the floating body is connected with the counterweight through a connecting rope; the water taking device comprises a water taking pipe and a floating frame arranged on the throwing line in a penetrating mode. A battery, a driving motor and a clamping transmission assembly are arranged in the floating frame. The clamping transmission assembly comprises two pressing wheels which are clamped on the throwing line in a matched mode. The driving motor is used for driving the two pressing wheels to rotate at the same time, and the rotation directions of the two pressing wheels are opposite; the first end of the water taking pipe is fixed to the floating frame and connected with the water pumping device through a water pumping pipe. A heavy head is arranged at the second end of the water taking pipe, and a clamping assembly capable of clamping or releasing the second end of the water taking pipe is arranged outside the side wall of the floating frame. The water taking device moves to a target position along a throwing line through autorotation of the two pressing wheels, the second end of the water taking pipe is released, water pumping sampling is carried out, and it is ensured that collected water samples are all water bodies with the fixed depth within the designated range.

    本发明提供一种水体采样装置,包括绕线轮、抛线、配重、抽水装置、浮体和取水装置;抛线的一端缠绕在绕线轮上,另一端固定在浮体上;浮体的底端通过连接绳与配重连接;取水装置包括取水管和穿设于抛线上的浮框,浮框内设有电池、驱动电机和夹紧传动组件;夹紧传动组件包括两个配合夹紧于抛线上的压紧轮;驱动电机用于驱动两压紧轮同时自转,且两压紧轮的自转方向相反;取水管的第一端固定在浮框上,并通过抽水管与抽水装置连接;取水管的第二端设有沉重头,且浮框的侧壁外部设有可夹持或释放取水管第二端的夹持组件;本发明通过两压紧轮自转使取水装置沿着抛线移动至目标位置,释放取水管的第二端,进行抽水采样,确保采集的水样均为指定范围内、固定深度的水体。
