Embodiment 1

[0105] Such as figure 1 and figure 2 As shown, a drainage system with a hydraulic check weir gate and a pump row, the drainage system includes:

[0106] The diverter well is arranged at the water inlet and the water outlet of the diverter well body;

[0107] The diversion well includes: a hydraulic check weir gate, the hydraulic check weir gate is arranged near the water outlet, and is used to control the amount of water passing through the water outlet;

[0108] Sunny day submersible sewage pump and rainy day submersible sewage pump, the drainage pipe of the sunny day submersible sewage pump and the rainy day submersible sewage pump extend to the outside of the shunt well body and are connected with the sewage riser.

[0109] According to the present invention, the drainage system further includes a control system, the control system includes a monitoring device and a control unit; the monitoring device is connected to the control unit in signal, and the control unit is co...

Embodiment 2

[0122] This embodiment provides a drainage system, the drainage system includes the drainage system described in Embodiment 1, and the drainage system also includes adjustment and storage facilities; On the branch branch of the pipeline.

[0123] When the regulation and storage facility is arranged on the branch road of the water outlet pipe, a sixth water conservancy switch is set on the outlet pipe at the downstream end of the branching position of the water outlet pipe. The sixth water conservancy switch is connected to the control unit with signals, and the control unit controls the opening degree of the sixth water conservancy switch according to the received signal.

[0124] When the regulation and storage facility is set on the outlet pipe, the water flows into the regulation and storage facility from the inlet end of the regulation and storage facility through the outlet pipe for storage. When the capacity of the regulation and storage facility reaches the upper limit,...

Embodiment 3

[0127] This embodiment provides a drainage system, the drainage system includes the drainage system described in Embodiment 1, and the drainage system also includes online processing facilities; It is branched from the branch road and the terminal is merged into the outlet pipe; or it is set on the branch branched from the outlet pipe and the terminal is connected to the natural water body.

[0128] When the online treatment facility is set on a branch where the outlet pipe is branched and the terminal is merged into the outlet pipe, a seventh water conservancy switch is set on the outlet pipe between the branch branch and the merged position; or , when the online treatment facility is set on the branch road where the water outlet pipe is branched and the terminal is connected to a natural water body, a seventh water conservancy switch is set on the water outlet pipe at the downstream end of the branch branch branch position. The seventh water conservancy switch is connected t...

Abstract

The invention discloses a drainage system with a hydraulic power non-return check gate and pump discharge and a drainage control method. A rainy day submersible sewage pump, a sunny day submersible sewage pump and the hydraulic power non-return check gate are arranged in the drainage system, according to the liquid level height or the water quality of the water body in a well body of a flow distribution well, whether or not the submersible sewage pumps work can be judged, and then reasonable distribution of the water body is achieved. In addition, reasonable drainage can be further conducted aiming at the water bodies at different water levels or of different water qualities, and accordingly the maximized treatment effect is achieved. The drainage system is particularly suitable for the situation that a pipe which is connected with a sewage treatment plant is located at high terrain so that gravitational discharge cannot be achieved, through the submersible sewage pump in the drainagesystem, the water body with low water quality in the well body of the flow distribution well is drained to the sewage treatment plant in a pump discharge mode, and when emergency flood discharge is conducted, the water body with low water quality can also be drained into the natural water body through water outlets.

Description

technical field [0001] The invention belongs to the technical field of drainage, and in particular relates to a drainage system with a hydraulic check weir gate and pump drainage and a drainage control method. Background technique [0002] At present, the drainage system of cities and buildings mainly includes diversion system, confluence system and mixed flow system, the main purpose of which is to realize the collection, transportation and treatment of water bodies. For example, a system that treats all wastewater in one way is called combined. It has only one drainage system, called the confluence system, and its drainage pipe is called the confluence pipe. The system that treats different types of wastewater in different ways is called the diversion system, which generally has two drainage systems. One can be called a rainwater system, which is used to collect rainwater and industrial wastewater with a very low pollution level that is directly discharged into the water...
