Problems solved by technology

Existing equipment for regulation and storage only simply intercepts or regulates and stores water bodies. When intercepting, there may be too much water upstream of the intercepting device, causing floods in the upstream. When regulating and storing, it is necessary to set up a regulation and storage pool on the pipeline. On the one hand, the regulation and storage capacity of the storage tank is relatively limited. Secondly, this method needs to have enough space to build the storage tank, which is difficult to realize.

Embodiment 1

[0028] The structure of a pipeline regulation and storage system in this embodiment is as follows: figure 1 As shown, the system includes a 1000-meter-long rainwater pipeline 1 laid under the ground R, and the rainwater pipeline 1 is provided with down-opening weir gates 1A, 2A and 3A in sequence against the direction of water flow. The liquid level sensor can detect the liquid level before and after the weir gate.

[0029] Further, the distance between the bottom opening weir gates 1A, 2A and 3A is 50-300 meters.

[0030] Further, the system further includes a controller, which is respectively connected to the liquid level sensor and the bottom opening weir gates 1A, 2A and 3A for receiving the liquid level detected by the liquid level sensor. Height signal, and according to the liquid level height signal, control the action of the lower opening weir gate upstream or downstream of the water storage area where the liquid level sensor is located.

Embodiment 2

[0032] The method for regulating and storing the pipeline regulation and storage system in embodiment 1 is:

[0033] First, set the closing height value of each bottom weir gate according to the flow rate of the pipeline to ensure that each bottom weir gate has a certain overflow height. The overflow height gradually increases; and the warning water level of each down-opening weir gate is set according to the excess flow of the pipeline and the water level detected by the downstream liquid level sensor of the most downstream down-opening weir gate;

[0034] Secondly, when the liquid level sensor detects that the water level in the downstream area of ​​the down-opening weir gate 1A exceeds a certain degree of fullness or rainfall, the controller controls each down-opening weir gate to close to the set height value according to the received signal ;The water body overflows from the top of the bottom opening weir gate to its downstream pipeline;

[0035] When the liquid level se...

Abstract

The invention relates to a pipeline regulation and storage system. The system comprises a pipeline, intercepting devices and liquid level sensors, wherein the pipeline is arranged obliquely, and the horizontal height of the upstream is larger than that of the downstream; the intercepting devices are arranged in the pipeline and intercept the pipeline into multiple water storage regions; each waterstorage region is provided with one liquid level sensor, and the liquid level sensors are used for detecting the liquid levels of the corresponding water storage regions. The intercepting device at each place can be controlled to be closed to the set height value, and then flow of the pipeline overflows from the tops of all the intercepting devices to the downstream of the pipeline. In this way,regulation and storage are realized with own space of the pipeline, peak staggering of downstream drainage can be realized, and city waterlogging is avoided.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a pipeline regulation and storage system and a control method thereof. Background technique [0002] In my country's urban drainage projects, regulating and storing facilities are widely used devices in the field of water treatment. Its main purpose is to regulate and store sewage and initial rainwater, so as to avoid urban floods caused by heavy rainfall or pipeline blockage somewhere. disaster. Existing equipment for regulation and storage only simply intercepts or regulates and stores water bodies. When intercepting, there may be too much water upstream of the intercepting device, causing floods in the upstream. When regulating and storing, it is necessary to set up a regulation and storage pool on the pipeline. On the one hand, the adjustment and storage capacity of the storage tanks is relatively limited. Secondly, this method needs to have enough sites t...
