Embodiment 1

[0044] When there are reservoirs upstream of the river, such as figure 1 For setting, the reservoir outlet is placed at the lowest ecological water level Hmin of the reservoir, and the reservoir outlet is used as a river replenishment point, and an electric regulating valve 4 is installed at the reservoir outlet to adjust the amount of replenishment water released from the reservoir into the river. The water supply source supplies water to the reservoir through the water supply pipeline 8, and the output end of the water supply pipeline 8 to the reservoir is the reservoir water supply point, and the water supply pipeline 8 is provided with a water supply pump 7 as a water delivery power device, and a water pump control cabinet 6 is provided to control the water supply pump 7 running. Set flow meter 5 in the river downstream relative to the water supply input point to measure the river flow Q, set liquid level switch 3 for the reservoir to detect the water level H of the reserv...

Embodiment 2

[0051] When there is no reservoir in the upstream of the river, its setting is relatively simple, such as Figure 4 As shown, the water replenishment input point is set at the upstream of the river, and the output end of the water replenishment pipeline 8 to the river is the water replenishment input point. Same as the first embodiment, a water replenishment pump 7 is installed on the water replenishment pipeline 8 as a water delivery power device, and a water pump control cabinet 6 is provided to control the operation of the water replenishment pump 7 . The difference is that a controller 2 is set as an information transfer station, the pump control cabinet 6 is connected to the controller 2 through a control cable, and the flow meter 5 is connected to a remote I / O module 9 through a signal cable to transmit the flow information to the controller 2 first , between the central control machine 1 and the controller 2, and between the controller 2 and the remote I / O module 9 can ...

Abstract

The invention relates to a method and system for urban small river ecological water compensation scheduling. The system comprises a water compensation source, a water compensation pipe connected with a river and the water compensation source, a water compensation pump on the water compensation pipe and a water pump control cabinet corresponding to the water compensation pump. A flow meter is arranged in the river in the downstream direction opposite to an output port of the water compensation pipe, the flow meter and the water pump control cabinet are in communication connection with a central controlling machine, and the central controlling machine regulates the conveying capacity of the water compensation pump through the water pump control cabinet so as to regulate water compensation flow of a water compensation input point to the river. According to the method, the system is utilized to schedule river flow Q to enable the river flow Q to be within an interval [0.8m, Qm], and the river is always under the ecological conditions. According to the system and the method, the problems that due to the fact that the water compensation quantity is randomly determined in the prior art, great water resource and energy waste is caused, the running cost is too high, and implementation cannot be performed are solved; and the problem that some scheduling methods are complex and high in technical difficulty and not suitable for urban small rivers is solved.

Description

technical field [0001] The invention relates to the technical field of environmental protection and resource comprehensive utilization, in particular to an ecological water replenishment scheduling method and system for small urban rivers. Background technique [0002] While my country's economy is growing rapidly and urbanization has made remarkable achievements, due to people's excessive development and utilization of environmental resources, the ecological and environmental problems of urban rivers have become more and more prominent. serious. Especially for many seasonal rivers, the dry season has become the norm. Ecological replenishment of rivers is considered to be a practical and effective technical measure to solve the water environment problems of small urban rivers. However, in the existing ecological water replenishment system for small urban rivers, the determination of water replenishment amount and the operation of the water replenishment dispatching system a...
