下面结合附图对本具体实施方式中技术方案部分的使用方法及其原理作进一步的阐述：Below in conjunction with the accompanying drawings, the use method and principle of the technical solution part in this specific embodiment will be further elaborated:

首先启动驱动电机23利用第四驱动连杆27和第三驱动连杆24驱动驱动杆3始终沿着导向滑槽28的长度方向来回往复移动，驱动杆3在来回往复移动的过程中分别通过第一驱动连杆5交替驱动驱动柱7沿着定位滑套8的轴向方向移动，驱动柱7在移动的过程中通过第二驱动连杆10带动活塞头12在套管13内来回往复移动，活塞头12在抽出的过程中第一单向阀21关闭，第二单向阀22打开，即可实现进水的目的，活塞头12在推出的过程中第一单向阀21打开，第二单向阀22关闭，即可实现排水的目的；First start the drive motor 23 and use the fourth drive link 27 and the third drive link 24 to drive the drive rod 3 to move back and forth along the length of the guide chute 28 all the time. A driving connecting rod 5 alternately drives the driving column 7 to move along the axial direction of the positioning sleeve 8. During the movement, the driving column 7 drives the piston head 12 to move back and forth in the sleeve 13 through the second driving connecting rod 10. During the process of pulling out the piston head 12, the first one-way valve 21 is closed, and the second one-way valve 22 is opened, so as to achieve the purpose of water inflow. The one-way valve 22 is closed to achieve the purpose of drainage;

从套管13内排出的水首先进入到沉降箱17，此时抽水过程中第一单向阀21是关闭状态的，因此沉降箱17内的水是完全静止的状态，水体内含混的泥沙在自然沉降的过程中透过篦子板27落入到收集罐18，也就是说本实施方式中的排水装置的排水管20出水是不间断的，沉降泥沙则是交替进行的；The water discharged from the casing 13 first enters the settling tank 17. At this time, the first one-way valve 21 is closed during the pumping process, so the water in the settling tank 17 is completely still, and the sediment mixed in the water In the process of natural settlement, it falls into the collection tank 18 through the grate plate 27, that is to say, the water discharge from the drain pipe 20 of the drainage device in this embodiment is uninterrupted, and the sedimentation is carried out alternately;

本具体实施方式中的篦子板27为多孔板状结构，其主要是为了起到扰流的作用，防止进入到沉降箱17内的水流扰动沉降在收集罐18内的泥沙。The grate plate 27 in this specific embodiment is a porous plate-like structure, which is mainly for the purpose of disturbing the flow, preventing the water flow entering the settling tank 17 from disturbing the sediment settled in the collecting tank 18 .

最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that it can still be The technical solutions described in the foregoing embodiments are modified, or some technical features thereof are equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
