After controlling the exogenous pollution of the river channel through various prevention and control measures, the sediment has become the internal source of the river channel pollution. Therefore, the research on the river channel sediment has gradually deepened. At the same time, in some laboratories or research institutes, it is often necessary to collect sediment samples for experimental analysis, and river sediment sampling is very difficult. For current laboratories and research institutes, the current sampling method uses trough-type digging tools. For deep water bodies, it often needs to be connected with a long handle, which is inconvenient to operate and cannot control the depth of mud extraction; Mud extractors and gravity mud extractors are often bulky, heavy, and labor-intensive, and the efficiency of mud extraction is not high. Applicable water depth is very limited by the device itself, and the depth of mud extraction cannot be controlled.

本发明使用时的步骤如下：The steps when the present invention is used are as follows:
(1)将活动支架打开，垂直于固定支座，根据水深情况，外接合适数量的外接套管，外接副管以及外接取泥管。组装完成后，将取样组合套管垂直扎入水中，待其稳定后，将旋转把手套于外接副管，并选定基准面后，记下外接套管外表面初始刻度线数值；(1) Open the movable support, perpendicular to the fixed support, and connect an appropriate number of external casings, external auxiliary pipes and external mud pipes according to the water depth. After the assembly is completed, plunge the sampling combination sleeve vertically into the water. After it is stable, put the rotating handle on the external auxiliary pipe, and after selecting the reference plane, write down the initial scale line value on the outer surface of the external sleeve;
(2)借助外力固定外接套管，用力旋动旋转把手，使副管逐渐螺旋状扎入底泥中，根据实验确定的取泥深度，待刻度线到达取泥深度后停止旋转旋转把手，此时，由于硬质弹簧的作用，使得取泥圆台侧面的内部紧紧压实底泥表面，与副管的内部组成相对密闭空间，如附图2所示；(2) Fix the external casing with the help of external force, and turn the rotary handle hard to make the auxiliary pipe gradually plunge into the bottom mud in a spiral shape. According to the mud extraction depth determined by the experiment, stop rotating the rotary handle after the scale line reaches the mud extraction depth. At the same time, due to the effect of the hard spring, the inside of the side of the mud extraction round table is tightly compacted on the bottom mud surface, forming a relatively closed space with the inside of the auxiliary pipe, as shown in Figure 2;
(3)通过手柄将底泥抽提装置的柱塞压至最下端，安装好第二外接取泥管，并将第二外接取泥管另一端与第一外接取泥管上的第二外接取泥管接头相连，整个装置组合完毕；(3) Press the plunger of the bottom mud extraction device to the lowest end through the handle, install the second external mud extraction pipe, and connect the other end of the second external mud extraction pipe to the second external mud extraction pipe on the first external mud extraction pipe. Take the mud pipe joint to connect, and the whole device is assembled;
(4)通过下压手柄，提升柱塞，此时单向水阀关闭，取泥管与抽提装置之间形成压力差；取样初期，残留于取泥管中的空气以及河水被吸入抽提装置；上抬手柄，下压柱塞，此时单向水阀打开，空气以及河水被排出；(4) By pressing down on the handle, the plunger is lifted. At this time, the one-way water valve is closed, and a pressure difference is formed between the mud pipe and the extraction device; at the initial stage of sampling, the air and river water remaining in the mud pipe are sucked into the pipe for extraction. Device; lift the handle up, press down the plunger, at this time the one-way water valve opens, and the air and river water are discharged;
(5)重复(4)数次之后，套在副管内的河道底泥将逐渐被吸入取泥管、外接取泥管直至抽提装置中；(5) After repeating (4) several times, the river bottom mud set in the auxiliary pipe will be gradually sucked into the mud pipe, the external mud pipe until the extraction device;
(6)在取样末期，由于底泥的损失，位于副管内底泥高度降低，使得取泥圆台在硬质弹簧的作用下逐渐靠齐副管下表面，硬质弹簧逐渐趋于自然状态，表观现象表现为抽提行为变得较为轻松，抽上物质几乎全部为河水，此时，取泥过程结束；(6) At the end of the sampling period, due to the loss of sediment, the height of the sediment in the auxiliary pipe decreased, so that the mud-taking round platform gradually moved closer to the lower surface of the auxiliary pipe under the action of the hard spring, and the hard spring gradually tended to the natural state. The visual phenomenon is that the extraction behavior becomes easier, and almost all the pumped substances are river water. At this time, the mud extraction process is over;
(7)取泥结束后，依次拆下外接取泥管，继而从底泥中提出取样组合套管，进行拆卸；对拆下的外接取泥管，依次连接抽提装置，关闭单向水阀，压出外接取泥管中的泥样进入取样瓶中，至此，取泥过程全部结束。(7) After the mud extraction is completed, remove the external mud extraction pipe in sequence, and then remove the sampling combination casing from the bottom mud for disassembly; connect the removed external mud extraction pipe to the extraction device in sequence, and close the one-way water valve , press out the mud sample in the external mud collection pipe and enter it into the sampling bottle, so far, the mud collection process is all over.
