Embodiment

According to embodiment the present invention is described in further detail below.

In water-filled closing pipe line, as long as drop is arranged, no matter the pipeline pilot process, water is to flow from high to lower, that is to say, in the middle of pipeline, water is to rise to higher position.Here it is siphon principle.And in fact, in the pipeline of sealing, be to allow certain air to exist, as long as volume of air is less than the volume of drop section pipeline water, siphonage still can be kept the continuous-flow of water, utilize to allow this characteristic of air in certain amount in the siphonic process and be used, periodically take out a certain amount of water, can realize not having the external force water lift.Water is to have contained huge energy in flowing, if can use, is a huge green energy resource.

As shown in Figure 1, suppose that the height of water is H, the pipeline highest point is h apart from the high water level place, and water is in flow process, and the h point has been arrived in the promotion of water.In the pipeline of sealing, allow to exist certain air, as the shared pipeline length of air is L, so as long as H＞L, what water still can continue flows, and this just means, after we take out the water of L section at highest point, can continue to keep flowing of water, just the water of water pipe L section delivered to the place of h height.

The process of fetching water as shown in Figure 1 is as follows: throttle down 4,4 ', 5,6, by valve 3,3 ' water filling in pipe, fill with back throttle down 3,3 ', and

open valve

5,6, siphonage can make current direction the 3rd pond 9 in first pond 7; Throttle down 1,2 is opened

valve

3,4, emits the water of L section, and throttle down 3,4 again, opens valve 1,2, finishes the process of once fetching water; Throttle down 1 ', 2 ', treat that the pipeline air is discharged after, open valve 3 ', 4 ', emit the water of L section, finish another water intaking process; Gas carries out repetitive operation after discharging again in waiting to manage, and realizes that need not external force delivers to second pond 8 with the water in first pond 7.

From energy point of view, this process is actually in the transformation of energy of having carried out water.Water is top-down to flow, and potential energy converting and energy has become kinetic energy, and siphon water lift process is to reduce flow velocity, has reduced the kinetic energy of water, make it change into the more potential energy of high water level.

Suppose H=10 rice, h=100 rice, L=＜10 meter, each water lift process need water usage V1=(h+H) * Φ=110 * Φ

Water lift amount V2=L * Φ=10 * Φ

Water consumption consumes potential energy P1=mgH=10 * V1 * g=1100 Φ g

Water lift produces potential energy P2=mg (h+H)=110 * V2 * g=110 * 10 Φ * g=1100 Φ g

Siphonic process has also produced equivalent potential energy when consuming potential energy.Certainly, consider the pipe friction loss and keep certain flow velocity that energy can not be changed fully, even but utilization ratio has only 50%, and also be very considerable energy, if be used, be very considerable clean energy resource.

The application of siphon water lift:

1, can be used for pumped storage, set up the water lift power station, finish generating or peaking generation.Water is being contained huge energy in flowing naturally, the regional energy bigger at mountain area nature drop is just bigger, all is to build reservoir to utilize the water energy in the past, but the reservoir dam construction project is great, submerge loss is very big, and water lift can reduce water consumption by the potential energy that improves water, and reservoir capacity is reduced significantly, thereby reduce the engineering difficulty, reducing engineering cost, if can make full use of, will be the huge energy, the variation of environment simultaneously and require lessly not have to influence to ecology substantially.All be better than wind resource with regard to natural resources source, river quantity, distribution and development cost, have the prospect of extensively utilizing.

2, utilize the natural drop in brook, river, water is carried to eminence, can be used for the particularly urbanite water consumption in mountain area of eminence, unnecessary water can be used for generating simultaneously, as long as certain water yield is arranged, finish water lift and generating requirement simultaneously, satisfy household electricity and the water needs of resident on the mountain.

3, can be used for forest extinguishing at some reservoirs of forest eminence reasonable Arrangement.

Obviously, the above embodiment of the present invention only is for example of the present invention clearly is described, and is not to be qualification to embodiments of the present invention.For those of ordinary skill in the field, can also make other multi-form variation and changes on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that technological scheme of the present invention amplifies out or change still are in protection scope of the present invention.
