Technical Problem

[0002]盐碱地是盐土和碱土以及其他不同程度盐化和碱化土壤的总称，其含盐量或碱化度较高，土壤结构不良、易板结，有机质含量低、养分贫瘠，保肥能力弱，影响作物生长，是一种性状较差、肥力较低的退化土壤，为了全面了解土壤盐碱化的成因、程度及动态变化工作人员需要对盐碱地地表水以及地下水进行检测，但是对水质进行检测时一般需要预先对水质进行采样，因此需要使用到采样装置，对地表水采样时工作人员直接采用相应的容器在其内部装取一定量的水，对地下水采样时工作人员预先打孔，随后再采用容器将孔内的水源装取一定的量后再进行检测，但是此方式仅仅是对同一水域的一个水层进行采样，需要对其它深度的水源进行采样时，工作人员需要二次采样，增加工序，延长水质采样工作的时间，从而耽误水质监测工作的进度，在使用时具有一定的局限性

Benefits of technology

[0013](1)第一采样腔与第二采样腔螺纹连接后实现单次操作同时采集地表水及地下水两个深度的水样，推拉杆联动控制第一阻挡环与第二阻挡环的启闭，避免二次打孔或重复操作，一定程度缩短了水质采样工作的时间，采用固定点位不同深度采样，消除位置误差，提升后续水质监检测结果的可靠性，第一采样腔和第二采样腔连接方式简单，便于工作人员操作，提高工作人员的使用体验。
