Do not go out the float parts among Fig. 5.Fig. 6 is the cross-sectional view of the duct member 10 of another embodiment of the present invention, and this duct member 10 has float parts 17.These parts 17 are made of two flexible pipes 17, and this flexible pipe extends to the other end from flush pipe 7 one ends.The supply and the tapping equipment of sky G﹠W are not shown among the figure, but it can adopt device shown in Figure 2.

To the present invention be described by description below to principle of the present invention and characteristics.Can in the basin of storehouse, move by flush pipe 7 suction districts, thereby the shot-like particle of precipitation just can be sucked in the flush pipe by the opening of minimum.Can adopt buoyancy to change the position of suction district.Present device is not fixed, and it need not large-scale building operations in reservoir.Concerning the reservoir of having built up in advance, These characteristics is suitable for too.

Sedimentary washing away is to carry out under the situation of not discharging the water in the reservoir, thereby do not have water and product losses.The process of washing away can not carried out the season of lack of water, so that the loss amount minimum of water, and discharge is when (arid) and pondage reach maximum value when being little value, and pondage remains unchanged.In flush water, can obtain high contents of precipitate.Present device only relies on gravity to keep on the go, in order to realize washing away a spot of energy of process need.Present device is operated, control is easy, and the process of washing away can be reversed, and can whenever repeating again in the process of washing away.

Above-mentioned principle has provided a kind of removal and has been built in the sedimentary mode that has in the reservoir of a large amount of sedimentary korneforos.The scope that sediment flows, there is not the regulatory region of nature in explanation already, as the lake in the water channel.Because artificial reservior finally also can be for sediment fills up, so its application life is very short.For this reason, people generally do not pay the utmost attention to the employing large reservoir, though large reservoir does not resemble small-sized being filled very soon with big slightly reservoir.Adopt the present invention, in small-sized and medium-sized reservoir, can keep regulated quantity, and can to avoid reservoir be that sediment fills up.The power station, river is not built in any reservoir that has a large amount of sedimentary korneforos of building in routinely, because reservoir can not be kept the regulated quantity of water behind certain hour.Water is supplied with in the net sediment, and to carry total amount big more, and the reservoir scale of day regulating pondage is big more, because it can not retaining.So people are just in any domination that is subjected to current in specific.Consequently the power station is determined size by minimum discharge and is matched with other energy.The result has only utilized the part of river energy potentiality, if people want to keep bigger regulated quantity aspect energy supply simultaneously, just must invest in additional energy supply system.The alternative measure of such scheme is to adopt super-huge reservoir, and this reservoir can be for sediment fill up in the investment life span of engineering, but its can bring problem and increase expenditure local population and environment.

Have a large amount of existing power stations and irrigating facility reservoir to need to repair at present, but just known to the people, above-mentioned reinstatement works is not also carried out on a large scale, and does not have good solution.Many so-called step power stations (becoming the power station, multistage river of series along a river) have been built up today.At present through people's effort, the best approach that is adopted is by making every grade of reservoir discharge water come reservoir is washed away, but consequently people's silt particle of managing to wash away but is deposited in the storehouse basin of next stage.By means of the present invention, people can handle the reservoir sediment that is positioned at higher step, simultaneously it are used as resource.The step reservoir that is positioned at the downstream is in addition also protected.

The present invention also can be used in engineering irrigation and the water facilities.About having the more rudimentary river condition in a large amount of sedimentary rivers, be used to help stable river bed, reduce the danger of supplying water, protect old farmland.Utilize the present invention also can realize the repeated use of irrigating facility, wherein irrigation water is through enough purifications, and the sediment that is washed away can be used to relative phreatic surface and raises the river and fully raise downstream area, so that can cultivate.
