For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

The terms "first", "second", etc. are only for the convenience of describing the present technical solution, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0029] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0030] Figure 1 The fluid pipe network system in one embodiment of the utility model is shown, which includes a pipe network and a monitoring system. Fluid (gas or liquid) flows in the pipe network, which is used to transport the fluid to multiple different users. The monitoring system is used to monitor the flow rate of the fluid in the pipe network at all times, and then determine whether there is a leak in the pipe network and the location of the leak point based on the monitoring results.

[0031] Specifically, the pipeline network includes a fluid supply pipeline 1, a delivery network, and a plurality of branch pipelines. Among them, there is at least one fluid supply pipeline 1, which is connected to the fluid source and is used to deliver fluid to the plurality of branch pipelines through the delivery network. The delivery network is connected to the fluid supply pipeline 1 and is used to transmit the fluid input from the fluid supply pipeline 1. Each branch pipeline is respectively connected to the delivery network, and each branch pipeline is connected to a user. Multiple branch pipelines are connected to different users and are used to deliver fluid to different users respectively.

[0032] Specifically, the transport network includes at least one transport pipeline. One end of the fluid supply pipeline 1 is connected to the first end of the transport pipeline. The first end of each branch pipeline is connected to a user, and the second end is connected to at least one transport pipeline. The fluid supply pipeline 1 transports the fluid to different users through different transport pipelines and branch pipelines.

[0033] The monitoring system includes a control module and a plurality of flow monitoring components. The control module is electrically connected to the plurality of flow monitoring components, and is used to receive the flow signals monitored by the flow monitoring components, and display the flow data. The flow range value can also be set. When the monitored flow data exceeds the range value, an alarm is issued to prompt the occurrence of pipeline leakage and the like. The flow monitoring component is set on the pipeline network, and is used to monitor the flow at the set position at all times, and transmit the flow data to the control module.

[0034] Wherein, each branch pipeline is provided with at least one flow monitoring component, and at least two flow monitoring components are provided at intervals on the delivery pipeline.

[0035] When it is put into operation, each flow monitoring component monitors the pipeline flow at its location in real time and transmits the flow data to the control module. When a leak occurs somewhere in the pipeline network, the flow monitoring component at the corresponding upstream / downstream location will change in value. Then, the location of the leak can be determined by the change in the value of the flow monitoring component (increase or decrease or become zero) and the change in the difference in flow values ​​between two adjacent flow monitoring components, thus realizing the function of locating the leak.

[0036] This application sets up a monitoring system so that when a leak occurs in the pipe network, the leak point can be located on a specific pipe section according to the data of the flow monitoring device, without spending a lot of manpower and material resources and a long time to check each pipeline one by one. It is highly versatile and can be applied to all kinds of pipe networks.

[0037] It should be understood that the control module can use existing technology to achieve the above effect. The flow monitoring component can also use existing technology to achieve the above effect.

[0038] It should be understood that the "fluid" can be a gas such as natural gas, or a liquid such as oil or water. No specific limitation is given here. The "user" can refer to various fluid-consuming plants in industrial plants, or natural gas products and water products in various residential buildings in residential areas.

[0039] In some embodiments, the flow monitoring component may be a flow meter or a flow switch, which may be made of existing technology.

[0040] Specifically, when a flow meter is used, an existing ultrasonic flow meter can be used. The ultrasonic flow meter can be arranged outside the pipe and detect the flow rate by ultrasonic waves. This is convenient for maintenance and installation on the existing pipe network. It should be understood that other types of flow meters may also be applicable.

[0041] It should be understood that when only one flow monitoring device is provided on the branch pipeline, it can be provided as far downstream as possible to avoid leakage at the downstream position of the flow monitoring device. If the flow monitoring device on the branch pipeline is provided at a relatively upstream position, its data will always be displayed as normal, which will result in the inability to accurately locate the leakage point according to the data changes of the flow monitoring device.

[0042] In some embodiments, at least two flow monitoring components may be provided on each branch pipe. When there are two flow monitoring components, one of the two is provided at the upstream end of the branch pipe as much as possible, and the other is provided at the downstream end of the branch pipe as much as possible.

[0043] When there is a difference between the flow monitoring value of the downstream end and the flow monitoring value of the upstream end, it can be determined that there is a leak between the two flow monitoring components of the branch pipeline, thereby reducing the need to determine other pipelines located upstream.

[0044] Specifically, at least three, four, etc., multiple flow monitoring components may be arranged at intervals on at least some of the branch pipelines. The number of flow monitoring components on each branch pipeline may be partially the same, all the same, or all different.

[0045] It should be understood that the number of flow monitoring components on each branch pipe is set according to the specific conditions such as the length of the branch pipe. When the branch pipe is long, multiple flow monitoring components can be set on it. When the pipe is short, only one flow monitoring component can be set. The number of flow monitoring components is set based on the ability to more accurately locate the leakage point, so as to avoid the distance between two adjacent flow monitoring components being too far, making it difficult to accurately locate the leakage point in the pipe section between them.

[0046] In some embodiments, if the number of flow monitoring components on the branch pipeline is at least three, the multiple flow monitoring components may be evenly spaced on the branch pipeline, or may be evenly spaced on at least a portion of the branch pipeline.

[0047] Specifically, the spacing distance may be less than or equal to 50 meters to ensure the accuracy of leakage point detection.

[0048] In some other optional embodiments, the interval distance may also be greater than 50 meters. For example, for some long-distance natural gas pipelines, a flow monitoring component may be set every several hundred meters or one kilometer.

[0049] In some embodiments, the number of the delivery pipelines can be set to at least three. At least two of the delivery pipelines are connected end to end to form a loop, and the two ends of the remaining delivery pipelines are respectively connected to the loop formed by the end to end connection. In this way, when one of the delivery pipelines in the loop leaks and needs to be blocked, the fluid can be transported to other branch pipelines through the delivery pipelines whose two ends are respectively connected to the loop, thereby ensuring the continuity of fluid delivery.

[0050] In this embodiment, the number of the delivery pipelines is three, which are now defined as a first delivery pipeline 2, a second delivery pipeline 3, and a third delivery pipeline 4 respectively.

[0051] The first end of the first delivery pipeline 2, the first end of the second delivery pipeline 3, and the first end of the third delivery pipeline 4 are respectively connected to the fluid supply pipeline 1. The second end of the first delivery pipeline 2, the second end of the second delivery pipeline 3, and the second end of the third delivery pipeline 4 are interconnected. Each branch pipeline is respectively connected to the first delivery pipeline 2 or the second delivery pipeline 3.

[0052] In some other optional embodiments, the number of the delivery pipelines can also be four, five or other majority. In addition to the first delivery pipeline 2 and the second delivery pipeline 3 connecting the branch pipelines, multiple pipelines parallel to the third delivery pipeline 4 can also be set to avoid fluid delivery through the parallel pipelines when other pipelines leak and need to be isolated and blocked.

[0053] It should be understood that the form of the conveying network shown in this embodiment is only one example. In some other optional embodiments, the number of the conveying pipeline can be one, that is, a longitudinal pipeline, and all branch pipelines are respectively connected to the conveying pipeline. When the number of the conveying pipeline is multiple, it can be arranged in any shape such as field shape, mouth shape, four-child shape, irregular shape, etc. The setting of its shape and number can be flexibly selected to adapt to the specific situation of the pipe network application.

[0054] Furthermore, a plurality of flow monitoring components are disposed at intervals on the first delivery pipeline 2 and the second delivery pipeline 3 , and at least two flow monitoring components are disposed on the third delivery pipeline 4 .

[0055] In this embodiment, the number of flow monitoring components on the third delivery pipeline 4 is two, which are respectively arranged at the upstream end and the downstream end of the third delivery pipeline 4 .

[0056] In some other optional embodiments, the third delivery pipeline 4 may be provided with three, four or other plurality of flow meters, the number of which needs to be flexibly set according to specific conditions such as the length of the pipeline itself.

[0057] Specifically, in this embodiment, the distance between two adjacent flow monitoring components on the conveying network may also be less than or equal to 50 meters.

[0058] It should be understood that, for a unified pipeline, the more flow monitoring components are arranged and the shorter the distance between two adjacent flow monitoring components is, the higher the accuracy of the monitoring system in monitoring and locating leaks will be.

[0059] Considering the layout cost, a flow monitoring device can be installed every 50 meters or so for visible pipe sections in the open air and underground corridors of the pipe network. For pipelines buried underground in the pipe network (underground pipelines), a flow monitoring device can be installed at intervals of about 10 to 20 meters. This ensures the accuracy of leak point detection and positioning while reducing the layout cost. This type of layout can be applied to branch pipelines or transmission pipelines. In some other optional embodiments, for pipe networks laid out over long distances, the spacing distance can be adjusted and expanded accordingly.

[0060] In some embodiments, the multiple flow monitoring components spaced apart on the conveying network can be spaced apart evenly. They can also be arranged in a targeted and non-uniform manner according to the layout of the conveying network or the connection between the conveying network and each branch pipeline. They can also be spaced apart evenly in some parts and spaced apart in a targeted and non-uniform manner according to specific circumstances.

[0061] For example, to further improve the accuracy of leak point determination, at least one flow monitoring device may be provided between two adjacent connection points of the delivery pipeline and the branch pipeline, so as to further improve the accuracy of leak point determination and the accuracy of leak point location on the pipeline network.

[0062] In some embodiments, at least one flow monitoring component may also be provided on the fluid supply pipeline 1 .

[0063] Taking the fire protection pipe network of an industrial plant as an example, the application is further explained:

[0064] like Figure 1As shown, in this embodiment, the pipeline network includes a fluid supply pipeline 1, a transmission network and a plurality of branch pipelines.

[0065] The transport network includes a first transport pipeline 2 , a second transport pipeline 3 , and a third transport pipeline 4 .

[0066] The first end of the first delivery pipeline 2, the first end of the second delivery pipeline 3, and the first end of the third delivery pipeline 4 are respectively connected to the fluid supply pipeline 1. The second end of the first delivery pipeline 2, the second end of the second delivery pipeline 3, and the second end of the third delivery pipeline 4 are interconnected. Each branch pipeline is respectively connected to the first delivery pipeline 2 or the second delivery pipeline 3.

[0067] There are ten branch pipelines, corresponding to the users of ten factory buildings. They are first defined as the first branch pipeline 5, the second branch pipeline 6, the third branch pipeline 7, the fourth branch pipeline 8, the fifth branch pipeline 9, the sixth branch pipeline 10, the seventh branch pipeline 11, the eighth branch pipeline 12, the ninth branch pipeline 13, and the tenth branch pipeline 14.

[0068] Among them, the first branch pipeline 5, the second branch pipeline 6, the third branch pipeline 7, the fourth branch pipeline 8, and the fifth branch pipeline 9 are sequentially connected to the first delivery pipeline 2 from the upstream to the downstream thereof. The sixth branch pipeline 10, the seventh branch pipeline 11, the eighth branch pipeline 12, the ninth branch pipeline 13, and the tenth branch pipeline 14 are sequentially connected to the second delivery pipeline 3 from the upstream to the downstream thereof.

[0069] The number of flow monitoring components is 42, wherein one flow monitoring component is provided on the fluid supply pipeline 1, which is now defined as a flow monitoring component 56.

[0070] Eight flow monitoring components are arranged on the first conveying pipeline 2, which are flow monitoring component 15, flow monitoring component 16, flow monitoring component 17, flow monitoring component 18, flow monitoring component 19, flow monitoring component 20, flow monitoring component 21 and flow monitoring component 22 from upstream to downstream.

[0071] Eight flow monitoring components are arranged on the second conveying pipeline 3, which are flow monitoring component 23, flow monitoring component 24, flow monitoring component 25, flow monitoring component 26, flow monitoring component 27, flow monitoring component 28, flow monitoring component 29 and flow monitoring component 30 from upstream to downstream.

[0072] Two flow monitoring components are arranged on the third delivery pipeline 4, which are respectively a flow monitoring component 31 and a flow monitoring component 32 from upstream to downstream.

[0073] The first pipeline 5 is provided with two flow monitoring components, which are flow monitoring component 33 and flow monitoring component 34 from upstream to downstream.

[0074] The second branch pipeline 6 is provided with two flow monitoring components, which are flow monitoring component 35 and flow monitoring component 36 from upstream to downstream.

[0075] The third branch pipeline 7 is provided with three flow monitoring components, which are flow monitoring component 37, flow monitoring component 38 and flow monitoring component 39 from upstream to downstream.

[0076] The fourth pipeline 8 is provided with two flow monitoring components, which are flow monitoring component 40 and flow monitoring component 41 from upstream to downstream.

[0077] The fifth branch pipeline 9 is provided with two flow monitoring components, which are flow monitoring component 42 and flow monitoring component 43 from upstream to downstream.

[0078] The sixth pipeline 10 is provided with two flow monitoring components, which are flow monitoring component 44 and flow monitoring component 45 from upstream to downstream.

[0079] The seventh pipeline 11 is provided with two flow monitoring components, which are flow monitoring component 46 and flow monitoring component 47 from upstream to downstream.

[0080] The eighth branch pipeline 12 is provided with three flow monitoring components, which are flow monitoring component 48, flow monitoring component 49, and flow monitoring component 50 from upstream to downstream.

[0081] The ninth pipeline 13 is provided with three flow monitoring components, which are flow monitoring component 51 , flow monitoring component 52 , and flow monitoring component 53 from upstream to downstream.

[0082] The tenth pipeline 14 is provided with two flow monitoring components, which are flow monitoring component 54 and flow monitoring component 55 from upstream to downstream.

[0083] At this time, the monitoring system is distributed throughout the pipe network. If there is a leak in the pipe network, the monitoring system can accurately determine the location of the leak based on the value changes of each flow meter.

[0084] It should be understood that in the process of making judgments, there are subtle differences in the way of judging whether a pipeline is leaking, depending on the number and position of the flow monitoring components on the pipeline. In general, if the value of the upstream flow monitoring component at a certain point (if there are multiple upstream flow monitoring components, it is the sum of the displayed values ​​of multiple upstream flow monitoring components) is equal to the value of the downstream flow monitoring component at the point (if there are multiple downstream flow monitoring components, it is the sum of the displayed values ​​of multiple downstream flow monitoring components), it means that there is no leakage at the point; if they are not equal, it means that there is a leakage at the point.

[0085] like Figure 1The four leak points shown are as an example:

[0086] If leakage occurs at the leakage point A, the value displayed by the flow monitoring component 55 is smaller than the value displayed by the flow monitoring component 54 .

[0087] If leakage occurs at the leakage point B, the value displayed by the flow monitoring component 32 is smaller than the value displayed by the flow monitoring component 31 .

[0088] If leakage occurs at the leakage point C, the sum of the displayed values ​​of the flow monitoring component 15 , the flow monitoring component 23 and the flow monitoring component 31 is smaller than the value displayed by the flow monitoring component 56 .

[0089] If leakage occurs at the leak point D, the sum of the displayed values ​​of the flow monitoring component 19 and the flow monitoring component 35 is smaller than the value displayed by the flow monitoring component 18 .

[0090] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
