Rapid and safe plugging device for flood dam burst
The invention discloses a rapid and safe plugging device for flood dam burst and relates to the field of flood disaster rescue. The device is composed of a floating body, a fixing piece and a sinking part. The floating body comprises a hollow shell which is elliptical or rectangular in overlook and has a major arc, rectangular or trapezoidal cross section, a reinforcing beam, a fixing frame, a bottom door and a hydraulic transmission device are arranged at the front section in the floating body, and the bottom door is opened along with the hydraulic transmission device and sinks into a flat-bottom ship or a box body or a cover body in water. When a dam is destroyed by flood, the floating body is pushed into water, the anchor is thrown down, the floating body rushes into the breach along with water flow to block the flood and sandy soil, at the moment, the empty ball drives the hydraulic transmission device to push the bottom door open, the flood and the sandy soil enter the floating body and sink under the action of the gravity of the floating body and the gravity of the sandy soil, and meanwhile, the floating body sinks under the action of the anchor, the mooring rope and the sand baffle. And the flood in the sandy soil is filtered out by the flood control net on the rear wall. Therefore, the breach is quickly and safely blocked to keep the dam. And compared with the background technology, the method is simpler, more practical and more superior.
一种洪水溃堤快速安全堵口装置涉及洪灾的抢险领域。它是由漂浮体、固定件、下沉部件组成。漂浮体包括俯视为椭圆、长方形，截面为优弧、矩形、梯形的空壳体，漂浮体体内前段设有加固梁、固定架，并且设有底门和液压传动装置，底门随液压传动装置打开并沉入水中的平底船或箱体或罩体。当洪水冲毁堤坝时，将漂浮体推入水中，将锚投下，漂浮体随水流冲入溃口中，阻挡洪水和沙土，此时空球策动液压传动装置将底门推开，洪水、沙土进入漂浮体，受漂浮体自重和沙土重力作用下沉，同时在锚和缆绳以及挡沙板的作用下，固定住溃堤，并由后壁的防洪网将沙土中的洪水滤出。从而快速安全地堵塞决口保住堤坝。比背景技术更简单、更实用，更优越。
