The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention are within the scope of the present invention; wherein the "and/or" keywords referred to in this embodiment denote and/or both cases, in other words, a and/or B mentioned in the embodiments of the present invention denote both cases a and B, A or B, and three states in which a and B exist are described, such as a and/or B, and denote: only A and not B; only B and not A; includes A and B.
Also, in embodiments of the present invention, when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" or "in communication with" another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right" and the like are used in the embodiments of the present invention for illustrative purposes only and are not intended to limit the present invention.
It should be noted that, in order to describe the present invention in more detail, so that those skilled in the art can understand the present invention more clearly and clearly, and further support the technical problems to be solved by the present invention and the corresponding technical effects to be achieved, before describing the present invention, the following explanation is made with respect to the term nouns involved in the present invention:
a rainwater branch pipe which is a pipe for transporting rainwater in the unit area pipe; a sewage branch pipe, which is a pipe for transporting sewage in the unit area pipe; the municipal rainwater pipe is a pipeline for conveying rainwater in municipal pipelines; municipal sewage pipes are pipes used for transporting sewage in municipal pipelines.
It will be appreciated by those skilled in the art that the above-described "stormwater", "sewage" are not limiting of the "manifold" function, nor are the "municipal stormwater", "municipal sewage" are limiting of the "manifold" function, but merely serve as a distinction. In other words, the rainwater branch pipe, the sewage branch pipe, the municipal rainwater pipe and the municipal sewage pipe can all use the same pipeline, or different pipelines, or pipelines with the same part and different parts, so the invention is not limited, and the pipelines which can realize liquid conveying are suitable for the invention and are also within the protection scope of the invention.
According to whether or not the rainfall behavior occurs, the periods involved in the present invention can be divided into a rainfall period and a non-rainfall period, wherein the rainfall period refers to the period in which the rainfall behavior occurs and can be understood as a rainy day; the non-rainfall period is a period opposite to the rainfall period, and refers to a period in which no rainfall behavior occurs, and can be understood as a sunny day. Or according to the rainfall, the period related to the invention can be divided into a rainfall period and a non-rainfall period, wherein the rainfall period refers to a period when the rainfall reaches a certain rainfall threshold value, and can be understood as a period when the rainfall is slightly larger; the non-rainfall period is a period of time opposite to the rainfall period, and is a period of time when the rainfall is less than the rainfall threshold, and is understood to be a period of time when there is no rainfall or when the rainfall is small.
In the invention, the specific mode of determining the rainfall period and the non-rainfall period is not limited, and the method can be selected and determined according to actual operation requirements; in other words, any of the above-described ways of determining the rainfall period and the non-rainfall period is applicable to the present invention. And how to judge whether rainfall occurs or not and how to judge whether rainfall reaches a certain rainfall threshold value or not, the judgment mode of the prior art is adopted, the invention does not aim at the judgment mode of whether rainfall occurs or not, and a determination mode for determining whether the rainfall reaches a certain rainfall threshold is limited, so long as the determination mode for obtaining whether rainfall occurs or whether the rainfall reaches a certain rainfall threshold can be realized, the method is suitable for the invention.
Furthermore, for the rainfall period, the rainwater can be divided into primary rainwater and middle and late stage rainwater, and the dividing mode can adopt a time-length method, a water quality method or a liquid level method in the prior art, for example, when the time-length method is adopted, the corresponding rainwater in the rainfall period is primary rainwater, and the corresponding rainwater in the middle and late stage rainfall is middle and late stage rainwater; if the water quality method is adopted, the rainwater is first rain when the concentration of the rainwater is higher than a certain concentration threshold value, and is middle-stage and later-stage rain when the concentration of the rainwater is lower than a certain concentration threshold value; if the liquid level method is adopted, the rainwater is first rain when the liquid level of the rainwater is lower than a certain liquid level threshold value, and is middle-late stage rain when the liquid level of the rainwater is higher than a certain liquid level threshold value.
Similarly, the mode of determining the first rain or the middle and later rain is not limited, and the mode can be selected and determined according to actual operation requirements; in other words, any of the above-described ways of determining the initial rain or the middle-late rain is applicable to the present invention.
Of course, it should be understood by those skilled in the art that, since certain errors are allowed in the actual process of draining rainwater and/or sewage, certain errors may exist in the specific division of each period, such as that the division nodes are not strict in the middle of the initial rain and the middle and late rain, so that the initial rain is mixed with the middle and late rain, or the initial rain/middle and late rain is mixed with a small amount of sewage, etc.; the operation effect caused by the error is negligible because the implementation effect of the whole technical scheme of the invention is not influenced, and the operation effect is not considered to be within the protection scope of the invention.
