Description
Technical field
The utility model relates to a kind of pipe outlet energy dissipator, particularly about a kind of pipe outlet current that can reduce to soil washing, reduce the pipe outlet energy dissipator of farmland soil erosion, belong to agricultural irrigation technology.
Background technique
The agricultural water of China accounts for about 70% of total water amount, and irrigation efficiency is low, and the water waste phenomenon is quite serious.Facts have proved that in a large number the loss of closely native canal water delivery is 10%-40%, and the loss of remote native canal water delivery even up to more than 50%; And piping transportation water irrigation can be accomplished zero evaporation and filter loss substantially, and has long service life, maintenance cost is low and is convenient to advantage such as management, so low-pressure pipe irrigation technology is universal in northern China well-irrigated area.
At present, prevent that in the outlet of piping transportation water irrigation especially movable tube high-velocity flow from mainly containing the technological scheme of soil washing: (1) with buffered water stream energies such as straw mattresses, the method life-span is short, poor effect between current and soil; (2) increase the device that blocks water such as net formula at the outflow tube mouth, increase local energy loss, reach and reduce flow rate of water flow, this mode can effectively reduce pipeline and go out flow velocity, but also limited the flow of pipe outlet simultaneously, can not under big flow, work, limited the application of this mode.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of pipe outlet current that can reduce to soil washing, reduces the pipe outlet energy dissipator of farmland soil erosion.
For achieving the above object, the utility model is taked following technological scheme: a kind of pipe outlet energy dissipator is characterized in that: it comprises the inner cylinder and a taper reflection part of a reflection afflux cover, a hollow; One end of described reflection afflux cover is outlet, and the other end is taper; Described inner cylinder runs through on the conoid end that is arranged on described reflection afflux cover, and is positioned at the outer described inner cylinder one end formation import of described reflection afflux cover; One end of described taper reflection part is fixedlyed connected with described inner cylinder, and the other end is provided with the reflection circular cone of a sealing, offers several simultaneously on described taper reflection part outer wall and goes out head piece; Form a reflection manifold between described reflection afflux cover, taper reflection part and the inner cylinder.
Described inner cylinder is provided with a support.
Be arranged at intervals with the adjusting groove that is used for regulating described reflection manifold volume size more than two circles on the outer wall of described inner cylinder.
The utility model is owing to take above technological scheme, and it has the following advantages: 1, the utility model adopts reflective current energy dissipating principle, and current are during by the taper reflection part, flow section increases suddenly, water (flow) direction changes simultaneously, eliminates the part flow energy, reduces flow rate of water flow; Secondly, current are collision mutually in the reflection manifold, thereby produces the flow energy loss, further reduces flow rate of water flow, eliminates the erosion of current to agricultural land soil.Simultaneously, because flow section amplifies gradually on the flow channels of the present utility model, so its flow to pipe outlet does not have influence substantially.2, the utility model is arranged at intervals with some circles and regulates groove on the outer wall of inner cylinder, by regulating sliding reflection afflux cover between the groove, size that can accommodation reflex manifold volume, thus the time of collision of current in the reflection manifold regulated easily, regulate the flow velocity in outlet port.The utlity model has simple in structurely, cheap, the characteristics of convenient and practical and reliable operation are suitable for large-area applications in pipe type water conveyance irrigation system.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model comprises the inner cylinder 2 and a taper reflection part 3 of a reflection afflux cover 1, a hollow.One end of reflection afflux cover 1 is outlet 4, and the other end is taper.Inner cylinder 2 runs through on the conoid end that is arranged on reflection afflux cover 1, and inner cylinder 2 one ends that are positioned at outside the reflection afflux cover 1 form import 5.One end of taper reflection part 3 is fixedlyed connected with inner cylinder 2, and the other end is provided with the reflection circular cone 6 of a sealing, offers several simultaneously on taper reflection part 3 outer walls and goes out head piece 7.Form a reflection manifold 8 like this between reflection afflux cover 1, taper reflection part 3 and the inner cylinder 2.
Working principle of the present utility model is that current change the flow direction through taper reflection part 3 and enter in the reflection manifold 8 in import 5 enters inner cylinder 2, are flowed out by outlet 4 at last.It mainly reduces flow rate of water flow by following two places: at first, current are during by taper reflection part 3, and flow section increases suddenly, and water (flow) direction changes simultaneously, eliminate the part flow energy, reduce flow rate of water flow; Secondly, current are collision mutually in reflection manifold 8, thereby produces the flow energy loss, further reduces flow rate of water flow.Simultaneously, because flow section amplifies gradually on the flow channels of the present utility model, so its flow to pipe outlet does not have influence substantially.
In the foregoing description, inner cylinder 2 is provided with a support 9, and 9 pairs of reflections of support afflux cover 1 plays a supportive role.
In the foregoing description, can on the outer wall of inner cylinder 2, be arranged at intervals with two circles and regulate grooves 10,10 ' (only as example, be not limited to this), by regulate groove 10 and adjusting groove 10 ' between sliding reflection afflux cover 1, size that can accommodation reflex manifold 8 volumes, thereby regulate the time of collision of current in reflection manifold 8 easily, regulate the flow rate of water flow at outlet 4 places.
The utility model only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
