Description

一种针对排水管网水质采样的装置及方法 技术领域
本发明涉及管网水质检测领域，尤其涉及一种针对排水管网水质采样的装置及方法。
背景技术
定期检测排水管网检查井内的水质，是诊断排水管网是否有地下水渗入的重要手段，为形成较好的对照结果，要求每次能采集到同一位置要求的水样。但随着管网的运行，检查井内部会逐渐的堆积形成沉积物，且检查井内沉积物的深度分布不同，这样在后续对同一位置进行水质采样时，常规市售水质采样器主要采用绳索水质采样器，其工作深度不易控制，无法很好的保证每次所采集到的水样为同一取样深度的水样，进而影响后续检测的结果，导致检测结果出现偏差；具体参见图1，为检查井没有沉积物时的水位高度，此时采用绳索水质采样器所采集的是水位高度为H的水样；具体参见图2，当检查井内有沉积物时，检查井内的水位会增加，此时采用绳索水质采样器所采集的是水位高度为H1的水样，而采用的要求实质上需要采集原有的水位为H的水样，这样就导致了两次采集到的水位并非同一高度水位。此外，在采用过程中常常因搅动沉积物，而使得每次采样都会因不同含量的沉积物而影响到水质数据质量。
例如现有的，CN210322446U，一种排水管网用采样装置，其通过在伸缩杆的末端设置吊桶来进行排水管网的采样，在采样过程中，无法精确控制每次取样的深度。
虽然在CN209356242U，一种污废水水质采样装置，其通过在斜杆段的末端设置采样容器，进而达到采用的效果，但是在采样过程中，同样无法精确控制每次取样的深度。
发明内容
针对上述问题，本发明的目的在于提出一种针对排水管网水质采样的装置及方法，此装置能够很好的适用于管网有不同厚度沉积物的水质采样，保证了在采样过程中，每次都能够采集到设定好的同一深度位置的水样，保证了采样精度，进而保证了后续计算精度和结果。

步骤七，水质采样：
带采样装置安装完成之后，手握提升机构将采样装置插入检查井内，并使得圆柱杆插入到检查井的底端，然后采集固定深度A位置的水样；
步骤八，水样取出：
采样后，将整个采样装置提出检查井，先将采样桶底部的沉淀体底部的干扰性沉积物排出，再将水样注入储存瓶送实验室检验；
步骤九，采样装置的回收：
完成采样后，将采样装置组件逐个拆解，安放于组件箱内，便于下次使用。
当A-C＜h时，换用另一型号的采样桶，选取采样桶的高度为C1，并保证A-C1≥h。
本发明有如下有益效果：
1、本发明装置能够很好的适用于管网有不同厚度沉积物的水质采样，保证了在采样过程中，每次都能够采集到设定好的同一深度位置的水样，保证了采样精度，进而保证了后续计算精度和结果。本发明克服了常规绳索水质采样器的缺点，构建一种型的适用于排水管网水质采样的设备组件，具有高度产业利用价值。

实施例2：
采用一种针对排水管网水质采样的装置进行水质采样的方法，包括以下步骤：
步骤一，沉积物6的深度检测：
采用市售的沉积物柱状采样器4测定检查井5内沉积物6的深度，将沉积物6的厚度计为h；同时测定检查井5内部水位高度为B；
步骤二，设定采样高度：
预先根据采样要求，设定需要的采样深度A，采样深度A是从检查井5的底部到采样点的高度值；
步骤三，采样桶1安装高度的标定：
取出支撑器2，根据所测定沉积物6的厚度h，在支撑器2的刻度线202上作出标识位置，此标识位置要保证安装采样桶1后，锥形桶体109底端距离圆柱杆201底端的距离D要大于沉积物6的厚度h，进而避免锥形桶体109的底端碰触沉积物6，即D≥h；
步骤四，采样桶1的安装高度确定：
根据步骤二中所设定的采样深度A，此采样深度A以采样桶1的第一进水口101和第二进水口105的顶端作为标记线，将采样桶1在支撑器2上安装高度定为A，并保证A-C≥h，C为采样桶1的高度；
步骤五，采样桶1的安装固定：
根据步骤四中所确定的安装高度，将采样桶1安装在支撑器2的圆柱杆201上，再通过螺母103将采样桶1锁定在支撑器2上；
步骤六，提升机构3的组装：
根据检查井5的深度，组装提升机构3，将多根竖杆301通过螺纹柱303和第二螺母套306之间的螺纹配合，逐节安装至工作高度，再将提升机构3与支撑器2相组装，再安装横杆304，形成提升机构；
步骤七，水质采样：
带采样装置安装完成之后，手握提升机构将采样装置插入检查井内，并使得圆柱杆201插入到检查井5的底端，然后采集固定深度A位置的水样；
步骤八，水样取出：
采样后，将整个采样装置提出检查井，先将采样桶1底部的沉淀体底部的干扰性沉积物排出，再将水样注入储存瓶送实验室检验；
步骤九，采样装置的回收：
完成采样后，将采样装置组件逐个拆解，安放于组件箱内，便于下次使用。
进一步的，当A-C＜h时，换用另一型号的采样桶1，选取采样桶1的高度为C1，并保证A-C1≥h。通过上述的布置，以防止采样桶1底端对沉积物产生扰动。
