The invention discloses a water conservancy project water quality detection sampling method and device, and relates to the technical field of water conservancy project water quality detection.The water conservancy project water quality detection sampling device comprises a ship body and a mounting table, a sampling depth adjusting mechanism is fixedly arranged on the top end face of the mounting table, and a sampling mechanism is arranged on the bottom end face of the sampling depth adjusting mechanism; when the sampling mechanism descends to the sampling depth and needs sampling, the servo motor rotates to drive the cam to adjust the angle, at the moment, the protruding position of the cam makes contact with the end face of the sliding rod, the sliding rod drives the connecting block and the sliding block to move, and when the sliding block moves to expose the upper water inlet to the outside, the water level sensing mechanism senses the water level. When the lower water inlet is formed in the sampling box, sampling operation can be started, the sampling accuracy is improved, the automation degree during sampling is improved, the problem of sampling difficulty can be solved, the sampling number is two, and the contingency of samples can be effectively prevented.

    本发明公开了一种水利工程水质检测取样方法及取样装置,涉及水利工程水质检测技术领域,包括船体和安装台,安装台顶端面固定设置有取样深度调节机构,取样深度调节机构底端面设置有取样机构,取样机构内壁固定设置有水位感应机构,本发明实用性强,当取样机构下降到取样深度需要取样时,伺服电机转动带动凸轮进行角度调节,此时,凸轮外突处与滑杆端面接触,滑杆带动连接块和滑块移动,当滑块移动至将上进水口暴露在外部,且下进水口在取样箱内部时,即可开始取样作业,提升取样的精准度,提升取样时的自动化程度,能够解决取样困难的问题,取样数量为双份,能够有效防止样品的偶然性的特点。
