Problems solved by technology

The water system in the southern part of my country is developed, and there are many lakes and rivers converging and flowing. The river channel relocation is mostly used for small river tributaries. During the relocation process, if the open channel water diversion method is used, although a better water diversion effect can be achieved, the relocation process is labor-intensive and time-consuming. , the cost is high, and the relocation of the river is mostly a temporary project, and the construction site is limited, so it is not easy to implement; while the method of water diversion using ordinary pumping pipelines has low construction costs and a small site occupancy rate, but it measures the water source in the river After the flow rate, the state of the water pump is controlled and a series of operations to adjust the diversion flow are done manually, which cannot achieve the effect of punctuality, and there are large errors in the measurement and calculation of man-made during the measurement process, which cannot meet the stability of the water area.

Abstract

The invention relates to a system for automatically controlling temporary water diversion. The system comprises a water diversion device, a central control processor and a water source flow velocity monitoring device arranged in a water source; the water diversion device comprises a water diversion pipeline and at least two water pumps connected with a water inlet of the water diversion pipeline; the water pumps are connected in parallel; the water source flow velocity monitoring device and the water pumps are electrically connected with the central control processor respectively; and the central control processor controls start and stop states of each water pump according to information transmitted by the water source flow velocity monitoring device. The system for automatically controlling temporary water diversion, provided by the invention, can be applied to river channel dredging engineering and can automatically control and regulate the water division flow according to the flow velocity of the water source in a river channel to achieve the technical effect of stabilizing water diversion.

Description

technical field [0001] The invention relates to the field of river dredging engineering in municipal engineering, in particular to an automatic control system for temporary water diversion. Background technique [0002] Municipal engineering involves the construction of various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation and lighting, and is an essential material basis for urban survival and development. [0003] Among them, because the river not only undertakes the task of discharging floods in the flood season and regional water production, but also undertakes the task of diverting and exchanging regional water. If the river channel is blocked and cannot communicate, it will affect a large area around it, and the rainfall and water produced in this area will not be drained naturally. Therefore, it is necessary to divert and relocate the river channel through the river channel reconstruction project in the mun...
