Also, in embodiments of the invention, when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When one component is said to be "in communication with" another component, it can be directly connected to the other component or intervening components may be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions used in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the present invention.

It should be noted that, in order to explain the present invention in more detail, so as to enable those skilled in the art to understand the present invention more clearly and clearly, and to support the technical problem to be solved and the technical effect that can be achieved by the corresponding of the present invention, before introducing the present invention, the following explanation is made for the term noun to which it relates:

a confluence branch pipe which is a pipe for transporting rainwater, sewage, or mixed water of rainwater and sewage 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 used for conveying rainwater in a municipal pipeline; municipal sewage pipes are pipes used for conveying sewage in municipal pipelines.

It will be understood by those skilled in the art that the terms "storm water", "sewage", and "mixed water" are not intended to limit the "branch pipe" function, nor are the terms "municipal storm water", "municipal sewage", and "pipe" function, but are merely used for distinguishing purposes. In other words, confluence branch pipe, sewage branch pipe, municipal administration downspout, municipal administration sewage pipe all can use same kind of pipeline, perhaps different kind of pipeline, perhaps the same, the partly different pipeline of part, this the utility model discloses do not do the injeciton, as long as can realize the pipeline of liquid transportation, all be applicable to the utility model discloses, also all be within the protection scope.

The period related in the utility model can be divided into a rainfall period and a non-rainfall period according to whether the rainfall behavior occurs, wherein the rainfall period refers to the period of the rainfall behavior and can be understood as a rainy day; the non-rainfall period is a period opposite to the rainfall period, and is a period in which no rainfall action occurs, and may be understood as a sunny day. Or according to the rainfall, the period related in the utility model can be divided into a rainfall period and a non-rainfall period, wherein the rainfall period refers to the period when the rainfall reaches a certain rainfall threshold value and can be understood as the period when the rainfall is slightly larger; the non-rainfall period is a period opposite to the rainfall period, and refers to a period when the rainfall is less than the rainfall threshold, and may be understood as a period when there is no rainfall or when the rainfall is small.

The utility model discloses, it is not limited to what kind of mode it belongs to rainfall period and non-rainfall period specifically, can select to confirm according to actual operation demand; in other words, any of the above-described manners of determining the rainfall period and the non-rainfall period is applicable to the present invention. And how to judge to whether rainfall takes place to and how to reach a rainfall threshold value to the rainfall and judge, adopt prior art's judgement mode can, the utility model discloses no longer to the judgement mode whether rainfall takes place to and whether reach the judgement mode of a rainfall threshold value to the rainfall and prescribe a limit to, as long as can realize whether the rainfall takes place, or whether the rainfall reaches the judgement mode of the judgement result of a rainfall threshold value, all is applicable to the utility model discloses the rainfall is taken place to the acquisition, and the rainfall is judged to the judgement mode of the judgement result of a rainfall threshold value is not reached.

Furthermore, for the rainfall period, the rainwater can be divided into the first rain and the middle and later rain, and the division manner can adopt a time-lapse method, a water quality method or a liquid level method in the prior art, for example, when the time-lapse method is adopted, the corresponding rainwater is the first rain in the rainfall period, and the corresponding rainwater is the middle and later rain in the middle and later periods of the rainfall; if a water quality method is adopted, when the concentration of the rainwater is higher than a certain concentration threshold value, the rainwater is the initial rainwater, and when the concentration of the rainwater is lower than a certain concentration threshold value, the rainwater is the middle and later stage rainwater; if the liquid level method is adopted, the rainwater is the initial rainwater when the liquid level of the rainwater is lower than a certain liquid level threshold, and the rainwater is the middle and later stage rainwater when the liquid level of the rainwater is higher than a certain liquid level threshold.

Similarly, the determination of which mode the initial rain or the middle and later rain belongs to is not limited, and the determination can be selected according to the actual operation requirement; in other words, any of the above-mentioned manners of determining the initial rain or the middle and later 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 drainage process of rainwater and/or sewage in the actual operation process, certain errors may exist in the specific division of each period, for example, there is an imprecise division node between the initial rain and the middle and late rain, which results in the early rain mixed with the middle and late rain, or the initial rain/middle and late rain mixed with a small amount of sewage; and because the operation that this error leads to influences owing to do not influence the utility model discloses whole technical scheme's implementation effect can be neglected, should not regard as with this not in the utility model protection scope in.

Example one

Please specifically refer to fig. 1, which is a schematic diagram of an overall structure of a storage and regulation device for a drainage system according to an embodiment of the present invention, the storage and regulation device for a drainage system specifically includes: the system comprises a confluence branch pipe 1, a sewage branch pipe 2, a rainwater port 3, a sewage interception pipe 6, a first diversion facility 4, an initial rain storage facility 5 and a second diversion facility 7.
