The utility model discloses in, be equipped with observation well and level sensor on the total drainage pipe, level sensor is connected with the online automatic monitoring appearance of quality of water.

The utility model discloses in, be equipped with the dam in the total drainage pipe, the rainwater is always arranged mouthful automatic valve and is set up in the bottom of dam, and the overflow space that overflows for the rainwater is left on the upper portion of dam.

The utility model discloses beneficial effect: the utility model discloses utilize the valve in automatic control valve control main drainage pipe and the initial stage rainwater pipeline, realized the initial stage of rainwater and collected to guarantee that not up to standard quality of water can not directly discharge municipal rainwater pipeline in, have characteristics such as rational in infrastructure, simple to operate, be fit for extensive use, leave the overflow space that spills over for the rainwater on the upper portion of dam moreover, with the smooth discharge of assurance rainwater.

Drawings

The invention will be further explained with reference to the drawings and the embodiments below:

FIG. 1 is a schematic structural diagram of the present embodiment;

FIG. 2 is a cross-sectional view of the main drain line;

fig. 3 is a cross-sectional view of an initial rainwater pipe.

Detailed Description

Referring to fig. 1 to 3, the drainage control system for ensuring standard drainage of a main drainage outlet according to the present embodiment includes a rainwater collection pipeline 1, an initial rainwater pipeline 2 connected to the rainwater collection pipeline 1, and a main drainage pipeline 3 connected to the rainwater collection pipeline 1, wherein a drainage end of the initial rainwater pipeline 2 is communicated with an initial rainwater collection pool 11, and a drainage end of the main drainage pipeline 3 is communicated with a municipal pipeline 10. The automatic rainwater collecting valve 4 is connected to the initial rainwater pipeline 2, the automatic rainwater collecting valve 4 is connected with the online automatic water quality monitor 5, the automatic rainwater main drainage valve 6 is connected to the main drainage pipeline 3, and the automatic rainwater main drainage valve 6 is connected with the online automatic water quality monitor 5. The automatic rainwater collecting valve 4 and the automatic rainwater main drainage outlet valve 6 both comprise drainage valves and controllers for controlling the drainage valves, and the controllers are electrically connected with a central processing unit of the online automatic water quality monitor 5; the online automatic water quality monitor 5 comprises a central processor, a water level sensor, a water quality detector and the like, wherein the water level sensor is arranged in the pipeline, and the central processor and the water quality detector are arranged outside the pipeline.

As the preferred embodiment, be equipped with observation well 7 on the total drainage pipe 3, be connected with water level sensor and water sample extraction pipe etc. of quality of water on-line automatic monitoring appearance 5 in the observation well 7, in the in-service use in-process, the quality of water detector install outside observation well 7 can, be convenient for install and maintain.

Further, a dam 8 is arranged in the main drainage pipeline 3, the automatic rainwater main drainage valve 6 is arranged at the bottom of the dam 8, and an overflow space 9 for rainwater to overflow is reserved at the upper part of the dam 8. The initial rainwater pipeline 2 is only provided with the rainwater collection automatic valve 4 and does not reserve an overflow space, so that rainwater is prevented from being poured into the initial rainwater collection pool 11.

The utility model discloses a work flow and principle as follows: the utility model discloses utilize the valve in automatic control valve control main drainage pipe 3 and initial stage rainwater pipeline 2, under usual state, two valves all are in normally closed state, when raining or have water to discharge, the water level risees, 5 perceptions of the online automatic monitoring appearance of quality of water 5 back this moment, signals are collected automatic valve 4 and are made its valve open for the rainwater, the rainwater passes through initial stage rainwater pipeline 2 and discharges to initial stage rainwater collecting pit 11, discharge behind the certain time, this time can be set for 15 minutes or more of a specified duration, automatic valve 4 self-closing is collected to the rainwater, the initial stage of accomplishing the rainwater is collected.
