Embodiment 1

[0030] as attached Figure 1-Figure 4As shown, a safe operation dispatching system for a water transfer project in a hilly area includes a diversion pool 1 arranged in the water transfer system, a pumping station forebay 4, a pumping station 5 composed of several fixed-speed water pumps and speed-regulating water pumps, and a water delivery system. Water pipeline 6, pressurized tunnel 9, non-pressurized tunnel 15 with inlet shaft 14 and outlet shaft 16, high ground pool 7, water diversion port 12 with water diversion valve, characterized in that: in the front pool 4 of the pumping station A water diversion gate 2 and a control gate 3 are provided upstream of the pressure tunnel 9, a flow regulating valve A8 is provided at the entrance of the pressurized tunnel 9, a regulating pool 10 is provided at the outlet of the pressurized tunnel 9, and an upstream of the water diversion port 12 is provided. There is a flow-regulating and pressure-regulating valve D11, a flow-regulating a...

Embodiment 2

[0047] as attached Figure 5-Figure 7 As shown, this embodiment is basically the same as Embodiment 1, the difference is that in this embodiment, a two-stage closed hydraulic control butterfly valve 30 is arranged upstream of the flow regulating and pressure regulating valve A8 at the entrance of the pressurized tunnel 9. A vacuum breaking valve 28 is arranged on the pipeline at the downstream high point of the flow regulating and pressure regulating valve A8 at the entrance of the pressurized tunnel 9 . And do not establish regulating pool at the outlet of pressurized tunnel 9.

[0048] The purpose of setting the hydraulic control butterfly valve 30 and the vacuum breaker valve 28 in this embodiment is to close the hydraulic control butterfly valve in two stages when the flow regulating and pressure regulating valve at the entrance of the pressurized tunnel cannot be closed normally, so as to prevent the downstream pipeline from being subjected to large pressure. When the h...

Abstract

The invention discloses a safe operation scheduling system for a water conveyance project in a hilly region. The system comprises a flow division pond, a pump station front pond, a pump station, a water conveyance pipeline, a pressure tunnel, a free-flow tunnel, a high pool and a division, wherein a diversion sluice and a regulating sluice are arranged in a water conveyance system on the upstream of the pump station front pond; a flow and pressure regulation valve is arranged at an inlet of the pressure tunnel; flow and pressure regulation valves are arranged on the upstreams of the diversion and the free-flow tunnel; a flow and pressure regulation valve is further arranged at the tail end of the water conveyance system; pressure meters, flow meters, water level gauges and timers are arranged at the pump station front pond, the water inlet and outlet ends of each water pump of the pump station, the diversion and temporary regulation points along a water conveyance line. The system further comprises a control unit, wherein the data acquisition end of the control unit is connected with the pressure meters, the flow meters, the water level gauges and the timers; the control end of the control unit is connected with a water pump control cabinet for controlling the water pumps, a flow and pressure regulation valve control cabinet for controlling the flow and pressure regulation valves and a control cabinet for controlling the regulating sluice, the diversion sluice and a diversion valve.

Description

technical field [0001] The present invention relates to a safe operation scheduling system of a water delivery project, in particular to the safe operation scheduling of a complex water delivery system with multiple ups and downs, long distances and high lifts in hilly areas with pressurized water delivery and pressurized gravity flow water delivery methods system. The invention also relates to a dispatching operation method using the safe operation dispatching system of the water delivery project. Background technique [0002] In long-distance high-lift pipeline water transmission projects in hilly areas, various types of water hammer accidents are relatively common, especially in projects with large fluctuations in pipeline elevation and complex terrain. There are also various examples of accidents. In the water delivery system, due to reasons such as turning on the water pump or other improper scheduling and operation methods, the pressure in the water delivery pipe will...
