A non-powered dam

摘要

Instead, the dam is opened and closed automatically by flowing water.;The existing reservoirs are all started and closed manually. The dam in this study is about the automatic opening and closing of the dam.;The reference drawing has a similar foundation to the first one, after forming the cylinder chamber "10", insert the cylinder box "12" in the cylinder chamber "10".Then, after the combination of "two" and "eight", add "seven" to "eight" at the bottom of the piston, and "Nine" for most pistons.Next, put the spray "1" of proper size in proper arrangement before and after the cylinder chamber "10", insert the sound dike into the cylinder sleeve "12" with both the water pressure plate "2" and the leather stone "8", and then fix "7" between the cylinder chamber "10" and the leather stone "8" to make it index.Then paste the flow axis "4" on the front and back of the water pressure plate "2" for dike, and paste the front and back inclined pipes "3" on the flow axis "4".Then, the lower end of the front and rear inclined plates "3" is pasted with the flow drum "6" at the same time, so that it is more convenient to move forward and backward when the dike is pressed with the water pressure plate "2", and then the "5" between the water pressure plate "2" and the inclined plate "3" is added, and then it is fixed on both sides.Then an index plate "5" is added to the lower end of the inclined tube "3", and a non dynamic automatic reservoir of the index tube "5" is fixed at the inclined plate "3".The effect is as follows:;If the rain causes more water to flow, the dam will be opened automatically according to the weight of water. If the flow of water becomes less, the dam will be closed automatically due to the restoring force of spring.
