海水养殖尾水移动式监测装置

本发明属于水质监测技术领域，具体公开了一种海水养殖尾水移动式监测装置，包括取水部、存水部和升降装置，取水部包括直管和取水芯，取水芯的外侧壁与直管的内侧壁密封滑动接触，且取水芯无法相对直管旋转。取水芯的侧面开设有多个取水空间，直管的侧壁在不同高度处开设有多个进水口，各个进水口在直管的轴线方向上不重叠，每个进水口在直管的轴线方向上仅与一个取水空间的开口重叠。升降装置控制取水芯沿直管内侧壁上下滑动。本发明能够避免使用水泵，直管内的存水在下次取样时可直接排出，或者在当次取样后在重力作用下直接排走，能够使用一根直管一次性提取不同深度的尾水样品，减少设备投入；每次提取样品体积恒定，无需特别控制。 The invention belongs to the technical field of water quality monitoring, and particularly discloses a mariculture tail water movable monitoring device which comprises a water taking part, a water storage part and a lifting device, the water taking part comprises a straight pipe and a water taking core, the outer side wall of the water taking core is in sealed sliding contact with the inner side wall of the straight pipe, and the water taking core cannot rotate relative to the straight pipe. A plurality of water taking spaces are formed in the side face of the water taking core, a plurality of water inlets are formed in the positions, at different heights, of the side wall of the straight pipe, the water inlets are not
