Description

TECHNICAL FIELD

[0001] The application is a pressure partition simulation device based on dynamic working conditions of pipe network, belonging to the technical field of pipe network. BACKGROUND

[0002] As the "vascular system" of urban water supply, pipe network undertakes the important mission of delivering energy such as tap water to various users. In order to ensure the stable delivery and efficient use of tap water in the pipe network, various control valves need to be installed at key nodes of the pipe network. At present, the traditional design process usually builds a static planar simulation pipe network model before the implementation of the pipe network project, collects data of each support point under typical working conditions, divides the pressure partition according to the data, and determines the installation position and specification of the valve body. However, the actual pipe network operating environment is much more complex than the simulation working conditions. The tap water in some local areas of the pipe network is always in a dynamic flow state, and the water pressure is significantly affected by factors such as peak and valley of water consumption, seasonal climate change, etc. The traditional static simulation method cannot capture these dynamic changes, resulting in deviations between the pressure partition obtained by analysis and the actual situation, and further affecting the operation effect of the pipe network and the quality of water supply. In addition, due to the various topological structures of the pipe network in different use scenarios, such as series or parallel connection, the traditional design needs to disassemble and rebuild the pipe network when the working conditions are converted. This not only greatly increases the project cycle, but also may cause the wear of pipe network sealing elements and the loosening of connection parts due to frequent disassembly and assembly, significantly increasing the risk of pipe network leakage, and ultimately causing the distortion of subsequent detection data, which seriously affects the accuracy and reliability of pressure partition optimization.

[0021] If the experimental study is carried out under the dynamic working condition of the pipe network in series, an appropriate amount of water is added to the water storage space below the partition plate 5 in the box 1 through the water adding pipe 12, and then the first three-way valve 31 and the plurality of second three-way valves 91 are started, so that the vertical pipe 93 and the water conveying pipe 3 are in a closed state, the connecting pipe 92 and the single pipe 82 are in a closed state, and the auxiliary pipe 83 and the single pipe 82 are in a flow-through state, so that the spiral pipe 8 is in a full communication state, thereby simulating the pipe network in series, and then the water pump 4 is started to pump the water in the water storage space to the tank 2.

When the water in the tank 2 reaches the appropriate amount, the water in the tank 2 is transported to the water delivery pipe 3, and then the water is transported to the vertical pipe 93 through the water delivery pipe 3, and then the water is transported to the multiple single pipes 82 through the multiple connecting pipes 92, respectively.

At this time, the pressure data of the pipe network under different water peak and valley and seasonal changes is collected by the sensor, and then the pressure data is analyzed and calculated, and a pressure space-time distribution model is established. On the basis of the model, an intelligent optimization algorithm such as genetic algorithm or ant colony algorithm is used to automatically find the optimal pressure partition boundary (i.e. the installation position and setting of the pressure reducing valve) and the arrangement scheme of the communication valve.

[0027] The mechanical change of the simulated series or parallel pipe network and the pipe network under dynamic working conditions is realized, the working efficiency is improved, the simulated pipe network is in a three-dimensional state, the occupied space is effectively reduced, the probability of leakage of the simulated pipe network due to disassembly and other factors is effectively reduced, the probability of errors in the subsequent detection data is effectively reduced, the subsequent pressure partition optimization effect and quality are high in accuracy, the branch pipe 81 is protected by the conical cylinder 71, and the branch pipe 81 is always in the simulation environment, thereby effectively reducing the probability of errors in the data collected by the sensor due to the blocking of the outer cylinder 7, effectively ensuring the subsequent pressure optimization effect and quality, and high in accuracy.

Since the conical rubber cover 62 itself has elasticity, when the sprayed water collides with the conical rubber cover 62, on the one hand, the sprayed water is slowed down, and on the other hand, the conical rubber cover 62 is deformed, thereby agitating the water recovered in the conical rubber cover 62, so that the water recovered in the conical rubber cover 62 can effectively enter the inner cylinder 6 through the second hole 64. Then the slowed down water enters the conical rubber cover 62 located on the lower side of the corresponding first hole 63, and then the water recovered in the conical rubber cover 62 enters the inner cylinder 6 through the second hole 64. Then the water in the inner cylinder 6 reenters the water storage space in the box body 1 through the mounting hole, thereby ensuring the recycling of water. The water sprayed from the plurality of branch pipes 81 is separated, which effectively reduces the probability of mutual interference between the upper and lower branch pipes 81 due to the spiral structure of the plurality of branch pipes 81, effectively reduces the probability of errors in detection data in the branch pipes 81, effectively ensures the subsequent pressure optimization effect and quality, and has high accuracy.

The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
