Description

Technical Field

[0001] The utility model relates to the field of pipeline leakage detection, in particular to a device for quickly locating leakage points of water supply and drainage pipelines in subway tunnels. Background Art

[0002] Drainage pipes within subway tunnels are typically laid along the sides or bottom of the tunnel. When located along the sides, they are typically laid along the tunnel walls to collect water seepage from the side walls and any water that may have flowed into the tunnel from other locations. This water is then directed to designated drainage pumping stations or collection wells. When located at the tunnel bottom, drainage pipes primarily collect accumulated water to prevent it from impacting train safety. Bottom drainage pipes are typically integrated with the trackbed structure, with a specific slope designed to ensure smooth flow of water into the pumping station or collection well.

[0003] The process of locating leakage points in the drainage pipes on both sides of the tunnel is primarily accomplished through the use of auxiliary tools such as leak detectors and infrared thermal imagers. However, these tools require operators to climb high and use probes to inspect each line one by one, which is a very labor-intensive task.

[0004] In view of this, how to quickly locate leakage points in water supply and drainage pipes in subway tunnels has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0041] Reference Figure 1The utility model provides a device for quickly locating leakage points in water supply and drainage pipes in subway tunnels, comprising a movable body 1, a detector body 2, a connecting rod, a running wheel 3, a power telescopic part 4 and a probe 5. The movable body 1 can be slidably connected to the two rails of the subway, and the detector body 2 and the probe 5 adopt an electronic leak detector structure, and the specific model is preferably Hikvision Micro-Image A5. The machine trains an intelligent leak detection model through a learning algorithm, effectively removes pipeline noise and environmental interference noise, accurately identifies the sound of water leakage and air leakage, and automatically assists in judging the leakage point. One end of the connecting rod is hinged to the movable body 1, and the other end of the connecting rod is equipped with a running wheel 3 and a power telescopic part 4. The running wheel 3 is used to frictionally connect with the side wall of the tunnel, thereby supporting the other end of the connecting rod. The fixed end of the power telescopic part 4 is connected to the other end of the connecting rod, and the movable end of the power telescopic part 4 is equipped with a probe 5. The probe 5 is electrically connected to the detector body 2, and the power telescopic part 4 is extended and retracted to enable the probe 5 to approach and move away from the side wall of the tunnel.

[0042] During use, the position and height of the drainage pipes in the subway tunnel are determined based on the construction drawings of the tunnel's water supply and drainage pipes. The movable body 1 is then placed on the two rails of the subway, and the running wheel 3 on the other end of the connecting rod is pressed against the inner wall of the tunnel. The power telescopic member 4 is controlled to extend so that the probe 5 is pressed against the inner wall of the tunnel, thereby determining whether there is a leak. After the test is completed, the power telescopic member 4 is retracted so that the probe 5 is away from the inner wall of the tunnel. At this time, the movable body 1 can be controlled to drive the probe 5 to change the test position and reach the next test location. The power telescopic member 4 is extended again so that the probe 5 is pressed against the inner wall of the tunnel for leak detection. The above steps are repeated to achieve a multi-point detection process.

[0043] Through the above method, operators do not need to climb high for inspection, but only need to push the walking vehicle to complete the long-distance multi-point inspection process, thereby reducing workload, improving inspection efficiency, and achieving rapid positioning effects.

[0044] During use of the present invention, the connecting rod is usually in an inclined state. In order to ensure that the running wheel 3 is in contact with the inner wall of the tunnel and that the power telescopic member 4 is extended so that the probe 5 can be pressed against the inner wall of the tunnel, the other end of the connecting rod of the present invention is connected to one end of an angle adjustment assembly, and the other end of the angle adjustment assembly is equipped with the running wheel 3 and the power telescopic member 4. The angle between the running wheel 3 and the connecting rod, and between the power telescopic member 4 and the connecting rod can be adjusted by the angle adjustment assembly, thereby ensuring that the running wheel 3 is in contact with the inner wall of the tunnel and that the power telescopic member 4 is extended so that the probe 5 can be pressed against the inner wall of the tunnel.

[0045] Reference Figure 3The other end of the angle adjustment assembly is fixedly connected to a connecting block 6. The end face of the connecting block 6, facing away from the angle adjustment assembly, is mounted with a travel wheel 3 and a power expansion member 4. The movable end of the power expansion member 4 is mounted with a connecting base 7. The connecting base 7 and the probe 5 are detachably connected. The connecting base 7 is provided with a mounting cavity, and a mounting block is provided at the rear end of the probe 5. The mounting block is detachably mounted within the mounting cavity. The probe 5 is connected to the detector body 2 via a wire. This detachable connection facilitates removal of the probe 5 from the connecting base 7 and storage with the detector body 2.

[0046] Reference Figure 2 The angle adjustment assembly includes a first connecting plate 8, a first connecting ear 9, a first adjustment rod 11, a second adjustment rod 10, a second connecting plate 12, a third adjustment rod 14 and a screw 15. Among them, the first connecting plate 8 is fixedly connected to the other end of the connecting rod, and two first connecting ears 9 are fixedly connected to the end surface of the first connecting plate 8 away from the connecting rod, and the first adjustment rod 11 and the second adjustment rod 10 are rotatably connected to the two first connecting ears 9. The second connecting plate 12 is fixedly connected to the connecting block 6, and the end surface of the second connecting plate 12 away from the connecting block 6 is fixedly connected to the second connecting ear 13. The second connecting ear 13 is hinged to the first connecting ear 9 through the second adjustment rod 10, and the third adjustment rod 14 is rotatably connected to the second connecting ear 13. The first adjustment rod 11, the second adjustment rod 10 and the third adjustment rod 14 are arranged in parallel. The middle part of the screw 15 is vertically rotatably connected to the first adjustment rod 11, one end is threadedly connected to the third adjustment rod 14, and the other end is installed with a screw rod 16. Rotating the screw rod 16 can drive the first adjusting rod 11 and the third adjusting rod 14 to move closer to or away from each other, thereby adjusting the angle between the first connecting plate 8 and the second connecting plate 12, changing the angle between the connecting rod and the connecting block 6, and further adjusting the inclination angle of the walking wheel 3 and the power telescopic part 4.

[0047] Refer again Figure 1 The present invention features a diagonal brace, one end of which is hinged to the movable body 1 and the other end to the middle of the connecting rod.

[0048] Preferably, the connecting rod includes a first connecting rod 17, a second connecting rod 19 and a first fastener 21. Among them, one end of the first connecting rod 17 is hinged on the movable body 1, and the first connecting rod 17 is provided with a plurality of first connecting holes 18 along its length; one end of the second connecting rod 19 is slidably plugged with the other end of the first connecting rod 17, and the other end of the second connecting rod 19 is installed with a walking wheel 3 and a power telescopic member 4, and the second connecting rod 19 is provided with a plurality of second connecting holes 20 along its length; the first fastener 21 is used to fasten at least one connecting hole and at least one second connecting hole 20. The first fastener 21 is preferably a bolt and nut structure, which is connected to the first connecting hole 18 and the second connecting hole 20 at different positions, so that the total length of the first connecting rod 17 and the second connecting rod 19 can be adjusted to be suitable for leakage detection of water supply and drainage pipes at different heights.

[0049] Preferably, the diagonal brace includes a first diagonal brace 22, a second diagonal brace 24, and a second fastener 23. One end of the first diagonal brace 22 is hinged to the movable body 1, and the second fastener 23 is installed at the other end of the first diagonal brace 22; one end of the second diagonal brace 24 is slidably plugged into the other end of the first diagonal brace 22, and the other end of the second diagonal brace 24 is hinged to the middle portion of the first connecting rod 17. The second diagonal brace 24 is provided with a strip hole 25, and the second fastener 23 passes through the strip hole 25 and is releasably locked to the second diagonal brace 24.

[0050] In one embodiment of the present invention, the second fastener 23 is a fastening bolt that extends through the strip-shaped hole 25 and is threadedly connected to the other end of the first diagonal brace 22. Tightening the fastening bolt locks the first diagonal brace 22 and the second diagonal brace 24 together, locking their overall length. Conversely, tightening the fastening bolt in the opposite direction allows the first diagonal brace 22 and the second diagonal brace 24 to slide relative to each other, allowing their overall length to be adjusted.

[0051] In the present invention, an earphone bracket 26 is fixedly mounted on the movable vehicle body 1 , an earphone 27 is detachably connected to the earphone bracket 26 , and the earphone 27 is detachably connected to the detector body 2 .

[0053] In addition, the present invention includes a battery 30 mounted on the movable body 1. The power actuator is an electric push rod. The push rod and the battery 30 are each electrically connected to a programmable logic controller (PLC) device (not shown). The battery 30 provides power for the push rod's extension and retraction, while the PLC device controls the push rod's extension and retraction process.
