The invention provides an unpowered sand suction device and method. The unpowered sand suction method is characterized in that a water storage tank is filled with water, all valves are closed, a vertical gravity suction head is underwater, a water adding valve and an air outlet valve are opened, water is injected into a siphon, and after water enters a siphon starting valve and the water level ofthe outlet end of a power generation pipe reaches a certain height, water at the inlet end of the vertical gravity suction head starts to flow to the outlet end of the power generation pipe; and the siphon starting valve gradually rises from the bottom of the original power generation pipe to one side to be fully opened along with the increase of the flow of a valve port of the siphon starting valve, and a siphon pipeline is formally started. According to the method, silt in a reservoir is discharged out of the reservoir in time through the sand suction pipe, the length of the power generationpipe can be manually set according to the actual situation on site and needs, the whole sand suction process is free of power consumption and valve resistance, impurities smaller than the pipe diameter can pass through the sand suction pipe, the sand suction efficiency is high, labor and time are saved, operation is convenient, and safety, environment friendliness and energy saving are achieved.The unpowered sand suction device and the unpowered sand suction method are suitable for use.
本发明提出了一种无动力吸沙装置及方法。向储水罐注满水，所有阀门都关闭且垂直重力吸头在水下，打开加水阀和出气阀，往虹吸管内注水，当虹吸启动阀进水后，动力发生管出口端水位达到一定高度时，垂直重力吸头入口端的水就会开始往动力发生管出口端流水，虹吸启动阀由原来的动力发生管底部随着虹吸启动阀阀口流量的加大逐渐升到一侧全开，虹吸管路正式启动。本发明通过吸沙管将水库中的泥沙及时的排出水库，可根据现场实际情况和需要人为设定动力发生管的长度，整个吸沙过程无动力消耗、无阀门阻力，只要小于管径的杂物都可以通过，吸沙效率高省工省力，操作方便、安全、环保、节能。适宜作为一种无动力吸沙装置及方法使用。
