Energy-free automatic drainage machine and drainage device thereof

Abstract

The invention discloses an energy-free automatic drainage machine and a drainage device thereof. The energy-free automatic drainage machine comprises a water holding device, a water valve, a three-way connector, a drainage connecting pipe and a water sucking connecting pipe. According to the invention, the energy-free automatic drainage machine has the advantages of very ingenious and simple design, environmental protection, convenience and better in applicability, has no need for adopting a drainage pump to pump water, can be ceaselessly used for a long time and can be used for long-distance drainage to ensure that environments of a steeper slope and a gentler slope are satisfied, a siphon channel can be rapidly formed and the distance control of siphon operation can be realized; the energy-free automatic drainage machine is suitable for small-scale water drainage and diversion, large pipelines can be adopted on the drainage connecting pipe, the water sucking connecting pipe and the three-way connector to ensure that large-scale water drainage and diversion such as flood discharge, water diversion of reservoirs and rivers and the like can be carried out by utilizing a same principle; and therefore, the energy is greatly saved, the efficiency is greatly increased and the social benefit is greatly improved.

Description

technical field [0001] The invention relates to a non-energy automatic drainage machine and its drainage device, in particular to a non-energy automatic drainage machine and its drainage device for draining water from a higher place to a lower place. Background technique [0002] At present, in many cases, places with higher terrain need to drain water to places with lower terrain, such as flooding, external drainage of reservoirs, pumping of ponds or fish ponds, water resource scheduling, etc., when pumping is required in the above situations , usually use a water pump or lay pipelines. When the amount of water to be pumped is large, the water pump needs to work for a long time, which not only consumes energy, but also requires a long time for equipment maintenance and laying. The equipment is not only expensive but also unstable. In the field In places where there is usually no electricity supply, only gasoline or diesel, which is expensive and pollutes the environment, ca...

Under this structure, the pressure difference of the liquid at both ends of the pipe can push the liquid over the highest point and discharge to the other end. It is mainly due to the gravitational force that makes the siphon work, and uses the principle of siphon to connect the high water surface and the low water surface through the pipe. The pressure difference of the liquid at both ends of the pipe leads the water from the high ground to the low ground. Not only does it not require energy, but it can easily overcome obstacles and can be used for a long time; but the key to this method is to form an underpressure in the connecting pipe. The simplest method is to pour liquid into the pipe. At present, most of the pipes are connected to the tap water outlet, filled with tap water, and then closed at both ends of the pipe. Place it on a higher ground and open both ends, but the weight
