Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipeline safety detection, and more specifically relates to a pipeline initial leakage collection and alarm device. Background Art
[0002] In environments like chemical plants, the media within pipelines can be corrosive. Failure to promptly address a leak can seriously threaten worker safety and potentially cause production line downtime. Leaks often occur at pipeline joints, often caused by improper joint handling. Furthermore, joints are stress concentration points, prone to loosening or even rupture due to uneven settlement or expansion. Therefore, early warning of leaks at pipe joints is crucial for leak prevention throughout the entire pipeline system.
[0003] In current pipeline system leakage prevention work, a receiving pan is usually set under the pipeline to receive the leaked liquid, and then the leaked liquid is detected by a sensor set in the receiving pan.
[0004] However, there is a certain height difference between the receiving pan and the pipeline. When the liquid falls from the pipeline into the receiving pan, a certain degree of splashing will occur, which will cause some of the liquid to splash outside the receiving pan, thereby causing environmental pollution. Utility Model Content
[0005] The utility model aims to provide a device for collecting and alarming initial leakage in a pipeline, so as to prevent leakage from dripping and splashing.
[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a pipeline initial leakage collection and alarm device, which is used to be arranged on a pipeline support, and the pipeline is mounted on the pipeline support, including:
[0007] A suspension bracket is provided on the pipe bracket;
[0008] a tray, arranged on the suspension bracket and located below the pipeline to collect liquid leaking from the pipeline;
[0009] an anti-splash wire mesh layer, laid on the tray and covering the collection surface of the tray; and
[0010] The detection alarm component is arranged on the tray and is used for detecting liquid leakage on the collection surface of the tray and generating an alarm signal.
[0011] In a possible implementation, the collecting surface of the tray adopts a recessed structure, and the recessed structure is used to collect the leaked liquid on the tray.
[0012] In a possible implementation, the detection alarm component includes:
[0013] a liquid leakage detection belt, fixedly disposed on the tray and arranged around the lowest point of the sunken structure;
[0014] A controller electrically connected to the liquid leakage detection device;
[0015] a signal transceiver, electrically connected to the controller and configured to send an alarm signal to the server host;
[0016] When the controller receives the liquid leakage signal from the liquid leakage detection belt, the controller sends a control signal to the signal transceiver, so that the signal transceiver sends an alarm signal to the server host.
[0017] In a possible implementation, a deflector cover is fixedly provided on the tray, and the deflector cover is located below the splash-proof wire mesh layer. The projection of the deflector cover on the tray covers the liquid leakage detection belt.
[0018] In a possible implementation, the lowest point of the recessed structure on the tray is connected to a leakage collection container.
[0019] In a possible implementation, the tray and the leakage collection container are connected via a drainage pipe.
[0020] In a possible implementation, a valve is fixedly provided on the liquid discharge pipe.
[0021] In a possible implementation, the drain pipe is threadedly connected to the leakage collection container.
[0022] In a possible implementation, the drain pipe extends to the interior of the leakage collection container.
[0023] In a possible implementation, the suspension bracket includes:
[0024] a first connecting member, hingedly arranged on the pipe support;
[0025] a second connecting member hingedly disposed on the tray;
[0026] The third connecting member has one end connected to the first connecting member by bolts, and the other end connected to the second connecting member by bolts, and the third connecting member is provided with a plurality of connecting holes for bolt connection along the height direction.
[0027] Compared to existing technologies, the present invention provides a device for collecting and alarming initial pipeline leakage. When a pipeline leak occurs, the leaked liquid first drips onto the anti-splash screen layer. This effectively mitigates the potential energy of the leaked liquid, preventing it from splashing and concentrating it within the tray. This not only improves the efficiency of leaked liquid collection but also prevents it from splashing into the surrounding environment, potentially contaminating and damaging other equipment or areas. Furthermore, the anti-splash screen layer also provides a filtering effect, intercepting some impurities. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0034] See Figure 1To facilitate understanding, the following describes the operating environment of the pipeline initial leakage collection and alarm device. A pipeline support 11 is fixedly installed on a building, and a pipeline 12 is mounted on the support 11. The pipeline initial leakage collection and alarm device is spaced apart along the length of the pipeline 12 and connected to the support 11. Leakage often occurs at the joints of the pipeline 12, so the pipeline initial leakage collection and alarm device is installed below the joints of the pipeline 12.
[0035] See Figure 1 and Figure 2 , the initial pipeline leakage collection and alarm device provided by the present invention is now described. The initial pipeline leakage collection and alarm device includes a suspension bracket 2, a tray 3, a splash-proof screen layer 4 and a detection alarm component. Among them, the suspension bracket 2 is fixedly set on the pipeline bracket 11. The tray 3 is fixedly set on the suspension bracket 2 and is located below the pipeline 12, and is used to collect the leakage falling from the pipeline 12. The splash-proof screen layer 4 is laid on the tray 3 and covers the collection surface of the tray 3. The detection alarm component is set on the tray 3, and is used to detect the leakage on the collection surface of the tray 3 and generate an alarm signal.
[0036] The suspension bracket 2 provides a stable support structure for the tray 3, ensuring that the tray 3 is accurately positioned below the interface of the pipe 12. This allows the tray 3 to be ready to collect any leaks without affecting the normal operation of the pipe 12. Because the tray 3 is fixed and its relative position to the pipe 12 is stable, any leak in the pipe 12 will drip directly onto the tray 3, greatly improving the efficiency of the leak collection.
[0037] Specifically, the splash-proof mesh layer 4 is a densely interwoven wire layer of elastic stainless steel wires, which has the characteristics of dense pores and high porosity, can effectively slow down the potential energy of dripping leaked liquid, prevent the leaked liquid from splashing, and quickly penetrate the leaked liquid into the tray 3.
[0038] As an alternative embodiment, the splash-proof mesh layer 4 can also be a sponge layer or a plastic honeycomb layer, so that when the leaked liquid falls, it can block the impact force of the leaked liquid, disperse the leaked liquid in the mesh, reduce the flow rate of the leaked liquid, and reduce the possibility of splashing.
[0039] When a leak occurs in pipe 12, the liquid first drips onto the anti-splash screen layer 4. The anti-splash screen layer 4 effectively prevents the leaked liquid from splashing, concentrating it within the area of the tray 3. This not only helps improve the efficiency of leaked liquid collection, but also prevents the leaked liquid from splashing into the surrounding environment and causing contamination and damage to other equipment or areas. At the same time, the anti-splash screen layer 4 also has a certain filtering effect, intercepting some impurities and preventing them from clogging and affecting the treatment of the leaked liquid.
[0040] The detection alarm component can quickly and accurately detect liquid leakage on the tray 3, and quickly generate and transmit an alarm signal, so that relevant personnel can be informed of the leakage at the first time and take emergency measures to deal with it, thereby minimizing the losses caused by the leakage.
[0041] In some embodiments, see Figure 1 The tray 3 has a recessed structure 31 that collects leaked liquid from the tray 3. The recessed structure 31 converges toward the center of the tray 3 and gradually slopes downward, with the center of the tray 3 being the lowest point of the recessed structure 31. This allows the leaked liquid to naturally flow toward the center of the tray 3, concentrating it in the central area of the tray 3.
[0042] In some embodiments, see Figure 1 and Figure 2 The detection alarm component includes a liquid leakage detection belt 51, a controller 52 and a signal transceiver 53. The liquid leakage detection belt 51 is fixedly set on the tray 3 and is set around the lowest point of the sunken structure 31. The controller 52 is fixedly set on the suspension bracket 2 and is electrically connected to the liquid leakage detection belt 51. The signal transceiver 53 is fixedly set on the controller 52 and is electrically connected to the controller 52 and is used to send an alarm signal to the server host. When the controller 52 receives the leakage signal from the liquid leakage detection belt 51, the controller 52 sends a control signal to the signal transceiver 53, so that the signal transceiver 53 sends an alarm signal to the server host.
[0043] The leakage detection belt 51 is set around the lowest point of the sunken structure 31 and can detect leakage flowing into the tray 3 from any direction in all directions to ensure that no leakage occurs. Once a leakage is detected, the leakage detection belt 51 immediately transmits the leakage signal to the controller 52, with a fast response speed. After receiving the leakage signal, the controller 52 responds quickly and sends a control signal to the signal transceiver 53, which reflects the automation and intelligence of the system and reduces the time and cost of manual intervention. The signal transceiver 53 sends the alarm signal to the server host, allowing relevant personnel to remotely monitor the pipeline leakage in real time and take timely countermeasures, thereby improving the efficiency and safety of management.
[0044] In some embodiments, see Figure 1 A deflector cover 6 is fixedly provided on the tray 3. The deflector cover 6 is located below the splash-proof screen layer 4. The projection of the deflector cover 6 on the tray 3 covers the leakage detection belt 51. Specifically, the deflector cover 6 is an upwardly raised arc-shaped plate, and the deflector cover 6 is fixedly connected to the tray 3 by a short column.
[0045] The deflector 6, located below the splash screen layer 4 and raised upward, guides leaked liquid from the deflector 6 toward the leak detection zone 51, ensuring timely detection of leaks. The deflector 6 covers the area of the tray 3 enclosed by the leak detection zone 51, preventing leaks from directly landing on the tray 3 within the leak detection zone 51 and potentially causing missed detection.
[0046] In some embodiments, see Figure 1 A leaked liquid collection container 7 is connected to the lowest point of the recessed structure 31 on the tray 3. Located at the center of the tray 3, the leaked liquid collection container 7 fully utilizes the recessed structure 31 of the tray 3, allowing the leaked liquid to flow naturally into the leaked liquid collection container 7 for collection. The leaked liquid collection container 7 provides a centralized storage space for leaked liquid, facilitating centralized processing and analysis. It can also store a larger amount of leaked liquid, allowing ample time for repairs to the pipeline 12.
[0047] In some embodiments, see Figure 1 and Figure 3 The tray 3 and the liquid leakage collection container 7 are connected by a drainage pipe 8, which is fixed to the tray 3. The drainage pipe 8 connects the tray 3 and the liquid leakage collection container 7, ensuring that the leaked liquid can flow smoothly from the tray 3 into the liquid leakage collection container 7. It provides a dedicated channel for the flow of the leaked liquid, preventing it from leaking into the surrounding environment during the flow process.
[0048] In some embodiments, see Figure 3 , a valve 81 is fixedly provided on the drain pipe 8. The valve 81 can control the discharge of the leaked liquid. When the leaked liquid in the leaked liquid collection container 7 needs to be processed, the valve 81 is closed to prevent the leaked liquid from flowing out of the tray 3, and the operation is convenient and quick.
[0049] In some embodiments, see Figure 3 The drain pipe 8 is threadedly connected to the leakage collection container 7. Specifically, a threaded connector 82 is fixedly provided on the drain pipe 8, and an external thread is provided on the leakage collection container 7, enabling a threaded connection between the threaded connector 82 and the leakage collection container 7. The threaded connection ensures a secure and reliable connection between the drain pipe 8 and the leakage collection container 7, making it less likely to loosen or fall off, and ensuring a tight seal at the connection. Furthermore, when leaked liquid in the leakage collection container 7 needs to be handled, quick disassembly and assembly are possible, making operation more convenient.
[0050] In some embodiments, see Figure 3The drain pipe 8 extends from top to bottom into the interior of the leakage collection container 7. Extending the drain pipe 8 into the leakage collection container 7 further enhances the sealing performance and prevents leakage at the interface. It also facilitates the smooth flow of leaked liquid into the leakage collection container 7, reducing the possibility of residual leaked liquid.
[0051] Based on the above embodiments, further, the effective volume of the leakage collection container 7 can be adjusted according to the length of the drain pipe 8 extending into the interior of the leakage collection container 7. Specifically, the drain pipe 8 is threadedly and tightly connected to the leakage collection container 7. In the early stage of leakage, the liquid flows along the wall of the drain pipe 8 or flows as a water film, and the gas in the leakage collection container 7 can be discharged through the drain pipe 8. When the liquid level in the leakage collection container 7 rises and is immersed to the lower end of the drain pipe 8, a water seal is formed. At this time, the air inside the leakage collection container 7 can no longer be discharged through the drain pipe 8, and the leaked liquid can no longer enter the leakage collection container 7. At this time, the liquid inside the leakage collection container 7 reaches the corresponding design volume, and the leakage collection container 7 no longer receives the leaked liquid.
[0052] It should be understood that the effective volume of the leakage collection container 7 may be determined by the maintenance response time of the staff after the alarm.
[0053] In some embodiments, see Figure 1 The suspension bracket 2 includes a first connecting member 21, a second connecting member 22, and a third connecting member 23. The first connecting member 21 is hingedly mounted on the pipe support 11. The second connecting member 22 is hingedly mounted on the tray 3. One end of the third connecting member 23 is bolted to the first connecting member 21, and the other end is bolted to the second connecting member 22. The third connecting member 23 has multiple connecting holes along the height direction for bolt connection.
[0054] Specifically, the tray 3 is a rectangular tray, and the number of the first connecting members 21 , the second connecting members 22 and the third connecting members 23 are four, and are respectively distributed at the four corners of the tray 3 .
[0055] The hinged design of the first and second connectors 21, 22 allows workers to adjust the height of the tray 3 by first disassembling the second and third connectors 22, 23 on one side of the tray 3, then selecting the appropriate connection holes and reconnecting the second and third connectors 22, 23. At this point, the tray 3 is tilted as a whole. The second and third connectors 22, 23 on the unadjusted side of the tray 3 can then be disassembled, the tray 3 adjusted to a horizontal position, and then the second and third connectors 22, 23 can be reconnected by selecting the appropriate connection holes. Since one side can be loosened first when adjusting the height, a certain degree of freedom is allowed for raising and lowering the tray, making the operation more convenient. Two people are no longer needed to simultaneously loosen the bolts on both sides, reducing manpower requirements and operational difficulty.
[0056] The multiple connection holes on the third connecting member 23 provide different height options. By selecting different connection holes for bolt connection, the height of the tray 3 can be adjusted to adapt to pipes 12 of different heights, providing sufficient operating space for staff and improving work efficiency.
[0057] In summary, the pipeline initial leakage collection and alarm device provided by the utility model provides a stable support for the tray 3 through the suspension bracket 2, compared with the prior art, ensuring that the tray 3 can be accurately located in the appropriate position below the pipeline 12. Once a leak occurs in the pipeline 12, the leak can directly drip onto the tray 3, greatly improving the efficiency of leakage collection. When a leak occurs in the pipeline 12, the leak first drips onto the splash-proof mesh layer 4. The splash-proof mesh layer 4 can effectively slow down the potential energy of the leaked liquid, prevent the leaked liquid from splashing, and concentrate the leaked liquid within the range of the tray 3. This not only helps to improve the efficiency of leakage collection, but also prevents the leaked liquid from splashing into the surrounding environment, causing pollution and damage to other equipment or areas. At the same time, the splash-proof mesh layer 4 can also play a certain filtering role, intercepting some impurities. The detection alarm component can sense the presence of leakage and quickly generate and transmit an alarm signal so that emergency measures can be taken to deal with it, thereby minimizing the losses caused by the leakage.
[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
