Description

Technical Field

[0001] This utility model relates to the field of pipeline leakage diagnosis technology, specifically a leakage diagnosis device for large-diameter water transmission pipelines. Background Technology

[0002] A waterway is a general term for pipes and channels that transport water from a long-distance water source to a point of use. In a broad sense, it refers to the entire long-distance water transport system, including pipes, open channels, culverts, and tunnels. In a narrow sense, it refers only to water transport structures that cross valleys, river valleys, or low-lying areas.

[0003] Chinese Patent Publication No. CN202020303723.X discloses a leak-proof PVC drain pipe, relating to the field of PVC technology. The pipe includes a movably connected connector on its outer side. The connector has grooves embedded at both ends and a water collection trough embedded on its inner side. A connecting ring is installed at one end of each pipe, and a snap-fit ​​ring is installed at the lower end of each connecting ring. Through-holes are located on both sides of the upper end of the pipe, with baffles installed inside each through-hole. Snap-fit ​​rings are provided to facilitate easy docking between connecting rings and further docking between pipes, improving the stability of existing pipes. The snap-fit ​​rings also prevent water leakage through gaps between pipes, thus preventing leaks. The baffles ensure that when a leak occurs inside the connecting pipe, water flows into the water collection trough and then into the through-holes.

[0004] The water pipeline described in the aforementioned patent, along with similar devices commonly found on the market, suffers from the common problem of not being able to accurately diagnose leaks during use. This results in workers being unable to locate and repair leaks in a timely manner, wasting a significant amount of water resources. Furthermore, the device cannot control leaked water during use, which can easily cause damage to the equipment. Utility Model Content

[0005] To address the aforementioned issues, a leak diagnosis device for large-diameter water pipelines is provided. A leak box is installed below the connection between the first and second drain pipes, and a water collection tray is installed inside the leak box. When a leak occurs at the pipe connection, liquid water enters the leak box and the water collection tray. The liquid water increases the weight of the water collection tray. When the leaked water inside the tray reaches a certain weight, the operating panel will rotate the diagnostic plate. When the diagnostic plate contacts the contact point, an alarm will be triggered to alert personnel that a pipeline leak has occurred, preventing delays in diagnosis and repair when a leak occurs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large-diameter water pipeline leakage diagnosis device, comprising a first drain pipe, a second drain pipe, a leak box, a water receiving tray, a movable plate, an operating plate, a diagnostic plate, contacts, and a drain pipe.

The leak box is disposed below the first drain pipe, the water receiving tray is disposed inside the leak box, the movable plate is disposed at both ends of the water receiving tray, the operating plate is rotatably mounted below the movable plate, the diagnostic plate is disposed on the side of the operating plate, the contacts are disposed at one end of the diagnostic plate, and the drain pipe is disposed inside the leak box and below the water receiving tray.

[0007] Furthermore, the lower positioning ring is disposed on the lower surface of the first drain pipe, and the lower positioning ring is connected to the leakage box through a support plate.

[0008] Furthermore, an upper positioning ring is rotatably mounted on one end of the lower positioning ring, and a locking screw that contacts the first drain pipe is threaded through the top of the upper positioning ring. A rubber pad is provided at the end of the locking screw that is close to the first drain pipe.

[0009] Furthermore, an annular groove is provided inside the lower positioning ring, and a rubber ring that contacts the first drain pipe and the second drain pipe is provided inside the annular groove.

[0010] Furthermore, the outer wall of the water receiving tray is symmetrically provided with rectangular holes that are adapted to the movable plate, a vertical rod is provided through the interior of the movable plate, a load-bearing plate connected to the leakage box is provided at the bottom of the vertical rod, and a reset spring for resetting is provided on the outer side of the vertical rod.

[0011] Furthermore, an extension rod is provided on the side of the operation panel, and the extension rod is rotatably mounted to the diagnostic panel via a working bearing. An alarm is electrically connected to the output end of the contact.

[0012] Furthermore, the side of the leakage box is symmetrically provided with positioning plates, and the side of the positioning plates is provided with matching protective covers.

[0013] Furthermore, an inclined tube is rotatably installed at the center of the water receiving tray, and a sealing plate is rotatably installed at the top of the inclined tube via a hinge. The diameter of the inclined tube is larger than the diameter of the drain pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this large-diameter water pipeline leakage diagnosis device is reasonable and has the following advantages:

[0015] (1) Install the leak box below the connection between the first drain pipe and the second drain pipe, and install the water receiving tray inside the leak box. When a leak occurs at the connection between the first drain pipe and the second drain pipe, liquid water enters the leak box and the water receiving tray. The liquid water will weigh down the water receiving tray and drive the movable plate to move during the pressing process. When the leaked water inside the water receiving tray reaches a certain weight, the operating plate will rotate. During the rotation of the operating plate, the diagnostic plate will rotate. When the diagnostic plate contacts the contact point, an alarm will be triggered to remind the staff that the pipeline is leaking, so as to avoid the inability to diagnose and repair the pipeline in time when a leak occurs.

[0016] (2) When the water receiving tray moves under the influence of liquid water, when the water receiving tray moves to the designated position, the drain pipe will be inserted into the inside of the inclined tube. At this time, the sealing plate will be flipped under the action of the hinge, so that the water inlet of the inclined tube will be opened. At this time, the liquid water inside the water receiving tray will be discharged under the action of the drain pipe, which can prevent the excessive liquid water inside the water receiving tray from damaging the device and improve the service life of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please refer to the following: Figures 1 to 5 A large-diameter water pipeline leak diagnosis device includes a first drain pipe 1, a second drain pipe 2, a leak box 3, a water receiving tray 4, a movable plate 5, an operating plate 6, a diagnostic plate 7, a contact 8, and a drain pipe 9. The second drain pipe 2 is located at one end of the first drain pipe 1, and the first drain pipe 1 and the second drain pipe 2 are connected by a working bolt. The leak box 3 is located below the first drain pipe 1, the water receiving tray 4 is located inside the leak box 3, the movable plate 5 is located at both ends of the water receiving tray 4, the operating plate 6 is rotatably mounted below the movable plate 5, the diagnostic plate 7 is located on the side of the operating plate 6, the contact 8 is located at one end of the diagnostic plate 7, and the drain pipe 9 is located inside the leak box 3 and below the water receiving tray 4.

[0025] Install the first drain pipe 1 and the second drain pipe 2 together. Then, install the leak box 3 below the connection between the first drain pipe 1 and the second drain pipe 2, and install the water collection tray 4 inside the leak box 3. When a leak occurs at the connection between the first drain pipe 1 and the second drain pipe 2, liquid water enters the leak box 3 and the water collection tray 4. The liquid water will weigh down the water collection tray 4, causing it to press down and drive the movable plate 5 to move during the pressing process. When the leaked water inside the water collection tray 4 reaches a certain weight, the operating plate 6 will rotate. During the rotation of the operating plate 6, the diagnostic plate 7 will rotate. When the diagnostic plate 7 contacts the contact point 8, an alarm will be triggered to alert the staff that a pipe leak has occurred. As the water inside the water collection tray 4 increases, the drain pipe 9 will be inserted into the water collection tray 4. At this time, the water inside the water collection tray 4 will be discharged under the action of the drain pipe 9, reducing the pressure on the water collection tray 4 and facilitating its recycling.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, the lower positioning ring 10 is disposed on the lower surface of the first drain pipe 1. The lower positioning ring 10 is connected to the leakage box 3 through a support plate. An upper positioning ring 11 is rotatably mounted on one upper end of the lower positioning ring 10. A locking screw 12 that contacts the first drain pipe 1 is threaded through the top of the upper positioning ring 11. A rubber pad is provided at the end of the locking screw 12 that is close to the first drain pipe 1. An annular groove is provided inside the lower positioning ring 10. A rubber ring 13 that contacts the first drain pipe 1 and the second drain pipe 2 is provided inside the annular groove.

[0027] When the device needs to be installed, the lower positioning ring 10 is installed below the first drain pipe 1 and the second drain pipe 2. At this time, the rubber ring 13 inside the first drain pipe 1 contacts the lower surface of the first drain pipe 1, which can effectively protect the outer surface of the first drain pipe 1. Then, under the action of the lower positioning ring 10, the upper positioning ring 11 is rotated and fixed. Then, the locking screw 12 on the top of the upper positioning ring 11 is rotated, which can make the installation of the upper positioning ring 11 and the lower positioning ring 10 more stable and improve the compatibility of the device.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, the outer wall of the water receiving tray 4 is symmetrically provided with rectangular holes that are adapted to the movable plate 5. A vertical rod 14 is provided through the interior of the movable plate 5. A load-bearing plate connected to the leakage box 3 is provided at the bottom of the vertical rod 14. A reset spring 15 for resetting is provided on the outer side of the vertical rod 14.

[0029] When liquid water leaks into the water receiving tray 4, the water receiving tray 4 drives the movable plate 5 to move inside the rectangular hole. When the movable plate 5 moves, it is adapted to the upright rod 14. The return spring 15 on the outside of the upright rod 14 can make the leakage box 3 have a certain reciprocating property. The elasticity of the return spring 15 is only enough to bounce up the water receiving tray 4 without water, which improves the practicality of the device.

[0030] like Figure 3 and Figure 5 As shown, an extension rod is provided on the side of the operation panel 6. The extension rod is rotatably mounted to the diagnostic panel 7 via a working bearing. An alarm is electrically connected to the output end of the contact 8.

[0031] When the movable plate 5 descends, it will rotate the operating plate 6. When the operating plate 6 rotates, it will drive the extension rod at the other end and the diagnostic plate 7 to rotate. When the diagnostic plate 7 contacts the contact point 8, the alarm can remind the staff to avoid the pipeline leak from being unable to be diagnosed and repaired in time.

[0032] like Figure 2 and Figure 3As shown, the side of the leakage box 3 is symmetrically provided with positioning plates 16, and the side of the positioning plates 16 is provided with a matching protective cover 17.

[0033] The protective cover 17 is installed under the action of the positioning plate 16. The protective cover 17 can protect the structure on both sides of the leakage box 3 and avoid errors caused by external objects.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, an inclined tube 18 is rotatably installed at the center of the water receiving tray 4, and a sealing plate 19 is rotatably installed on the top of the inclined tube 18 via a hinge. The diameter of the inclined tube 18 is larger than the diameter of the drain pipe 9.

[0035] When the water receiving tray 4 is pressed down to the designated position by the liquid water, the drain pipe 9 will be inserted into the inclined pipe 18. At this time, the sealing plate 19 will flip over, and the liquid water inside the water receiving tray 4 will be discharged under the action of the inclined pipe 18 and the drain pipe 9, so as to avoid excessive liquid water inside the water receiving tray 4 from damaging the device.

[0036] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
