Description

Technical Field

[0001] This application relates to the field of detection devices, and in particular to a pipe gallery leakage detection device. Background Technology

[0002] Wastewater treatment pipe corridors are typically composed of a large number of densely arranged pipes. Because the pipes operate in a humid and corrosive environment for a long time, the joints between adjacent pipes are prone to damage, causing leakage of the wastewater transported inside the pipes. Therefore, in daily operation, it is usually necessary to conduct regular inspections of the pipes inside the corridor in order to detect and deal with the leaks in a timely manner.

[0003] Currently, there are two common methods for inspecting utility tunnels: manual inspection and robotic inspection. Manual inspection is inconvenient and inefficient, and also poses certain safety hazards. While robotic inspection can effectively improve efficiency compared to manual inspection, some utility tunnels have complex layouts and insufficient lighting, making it difficult for robots to accurately locate leaks. Therefore, there is room for improvement. Utility Model Content

[0004] To facilitate the detection and location of leaks at pipe connections, this application provides a pipe gallery leak detection device.

[0005] This application provides a pipe gallery leakage detection device, which adopts the following technical solution:

[0006] A pipe gallery leakage detection device includes a detection ring, which is used to be fitted around the outer periphery of the pipe connection; the detection ring is composed of two symmetrically arranged semicircular rings spliced ​​together, and the two semicircular rings are connected by a connecting component; a plurality of humidity sensors are evenly distributed on the concave side of the semicircular ring.

[0007] By adopting the above technical solution, two semi-circular rings are spliced ​​together to form a detection ring, which is then fitted onto the outer circumference of the connection between adjacent pipes. When a leak occurs at the pipe connection, the humidity sensor can detect it in a timely manner and quickly provide a feedback signal, thereby facilitating maintenance personnel to quickly locate the pipe leak point. Compared with traditional pipe inspection methods, this effectively reduces the difficulty of detecting and locating pipe leak points.

[0008] Preferably, each of the concave sides of the semicircular ring is provided with an arc-shaped mounting groove, and the humidity sensor is located in the arc-shaped mounting groove.

[0009] By adopting the above technical solution and installing the humidity sensor in the arc-shaped mounting groove, it is beneficial to reduce the interference of changes in external environmental humidity on the humidity sensor, thereby ensuring that the humidity sensor can more accurately monitor and detect the connection between adjacent pipes.

[0010] Preferably, a wireless transmission module is installed on the outer side of the semicircular ring, and the humidity sensor on the concave side of the semicircular ring is wired to the wireless transmission module.

[0011] By adopting the above technical solution, and by connecting the humidity sensor to the wireless transmission module located outside the semi-circular ring, it is beneficial to ensure that the feedback signal of the humidity sensor can be stably transmitted to the wireless transmission module located outside the arc-shaped mounting groove, and then transmitted to the external device through the wireless transmission module, so that the external device can better obtain the feedback information of the humidity sensor.

[0012] Preferably, the arc-shaped mounting groove is open at both ends, and the arc-shaped mounting grooves of the two semicircular rings are spliced ​​together to form an annular groove.

[0013] By adopting the above technical solution, when a leak occurs at any location in the pipeline, the humidity sensors in the two semi-circular arc-shaped mounting grooves can better sense humidity changes, thereby improving the accuracy and sensitivity of the detection.

[0014] Preferably, the connecting assembly includes a connecting block and a bolt and nut; both ends of the semicircular ring are provided with ear plates; the two ends of the semicircular ring are respectively a hinged end and a movable end; the ear plates at the two hinged ends of the semicircular ring are hinged to each other through the connecting block, and the ear plates at the two movable ends of the semicircular ring are connected to each other through the bolt and nut.

[0015] By adopting the above technical solution, when installing the detection ring, the two semicircular rings are swung so that they fit around the outer circumference of the adjacent pipe connection. Then, the lugs at the movable ends of the two semicircular rings are connected by bolts and nuts, which can restrict the swinging of the two semicircular rings and ensure that the detection ring can be stably installed on the outer circumference of the pipe connection.

[0016] Preferably, the connecting assembly includes a connecting block and a connecting sleeve; both ends of the semicircular ring are provided with ear plates; the two ends of the semicircular ring are respectively a hinged end and a movable end, the ear plates at the two hinged ends of the semicircular ring are hinged to each other through the connecting block, and the connecting sleeve is sleeved on the ear plates at the two movable ends of the semicircular ring.

[0017] By adopting the above technical solution, when installing the detection ring, the two semicircular rings are swung so that they fit around the outer periphery of the adjacent pipe connection. Then, the connecting sleeve is put into the ear plate at the movable end of the two semicircular rings, which can restrict the swing of the two semicircular rings and make the detection ring securely installed on the outer periphery of the pipe connection.

[0018] Preferably, the connecting assembly includes a bolt and a nut; both ends of the semicircular ring are provided with lugs; the lugs at the adjacent ends of the two semicircular rings are connected by the bolt and nut.

[0019] By adopting the above technical solution, when installing the detection ring, after fitting two semicircular rings onto the outer circumference of the adjacent pipe connection to form a detection ring, the ear plates at the near ends of the two semicircular rings are connected by bolts and nuts, so that the detection ring can be securely fitted onto the outer circumference of the pipe connection.

[0020] Preferably, the concave sides of the semicircular ring are covered with flexible pads.

[0021] By adopting the above technical solution, the flexible pad can, on the one hand, limit the rigid contact between the detection ring and the pipeline, reducing stress concentration during the installation of the detection ring and preventing damage to the pipeline. Simultaneously, the flexible pad can also improve the sealing between the detection ring and the pipeline, preventing external impurities and moisture from entering the gap between the detection ring and the pipeline and interfering with the normal detection of the humidity sensor inside the semi-circular ring.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When a leak occurs at a pipe connection, the humidity sensor on the concave side of the semi-circular ring can promptly send a signal back to external equipment, allowing maintenance personnel to quickly determine the location of the leak and making leak detection and location at pipe connections simpler and more convenient.

[0024] 2. The opening of the arc-shaped mounting groove on the concave side of the semi-circular ring allows the humidity sensor to be accommodated and installed inside the arc-shaped mounting groove, effectively avoiding interference from the external environment for normal detection of the humidity sensor.

[0025] 3. Using connecting components to connect and fix the two semicircular rings helps to make the detection ring formed by splicing the two semicircular rings more securely fitted on the outer circumference of the pipe. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a pipeline leakage detection device.

[0036] Example 1

[0037] A pipe leakage detection device, referring to Figure 1 and Figure 2 The system includes a detection ring 1, which is fitted around the outer periphery of the connection between adjacent pipes. The detection ring 1 is composed of two semicircular rings 11 joined together. Several humidity sensors 2 are installed on the concave side of each semicircular ring 11, and these sensors are evenly distributed along the concave side. The humidity sensors 2 are used to monitor the connection between adjacent pipes in real time. When a leak occurs at the corresponding pipe connection, the humidity sensors 2 can promptly send a signal to external equipment, facilitating rapid location of the leak.

[0038] Reference Figure 1 and Figure 2 Each semicircular ring 11 has an arc-shaped mounting groove 10 on its concave side, with open ends. The arc-shaped mounting grooves 10 of the two semicircular rings 11 are joined together to form an annular groove. The humidity sensors 2 corresponding to the semicircular rings 11 are installed in the arc-shaped mounting grooves 10. After the two semicircular rings 11 are joined together to form a detection ring 1 that is fitted around the outer circumference of the pipe, the humidity sensors 2 are placed in a relatively enclosed space. This helps to limit the interference caused by changes in external humidity to the humidity sensors 2, and allows the humidity sensors 2 in the two semicircular rings 11 to more accurately monitor and detect the pipe connection.

[0039] By setting the arc-shaped mounting groove 10 open at both ends, the two semi-circular rings 11 can be spliced ​​together to form the detection ring 1. The arc-shaped mounting grooves 10 inside the two semi-circular rings 11 can form an annular groove, which is beneficial for the humidity sensor 2 inside the two semi-circular rings 11 to more comprehensively detect and monitor the leakage points at the pipe connection.

[0040] Wireless transmission modules (not shown in the figure) are installed on the convex sides of the semicircular ring 11. In actual use, the wireless transmission modules are wirelessly connected to external devices. Humidity sensors 2 within the arc-shaped mounting groove 10 are all connected to transmission wires. The semicircular ring 11 has corresponding connection holes for the transmission wires. The transmission wires pass through these holes and connect to the wireless transmission modules, thus establishing a wired connection between the humidity sensors 2 and the wireless transmission modules. The transmission wires ensure that the feedback signals from the humidity sensors 2 located within the arc-shaped mounting groove 10 of the semicircular ring 11 can be stably transmitted to the wireless transmission modules, which then relay the signals to the external devices.

[0041] Reference Figure 1 and Figure 2 Flexible pads 12 are glued to the concave sides of the semicircular ring 11. In this embodiment, the flexible pads 12 are rubber pads. The flexible pads 12 help limit the rigid contact between the semicircular ring 11 and the outer wall of the pipe when two semicircular rings 11 are subsequently spliced ​​and installed on the pipe, reducing the possibility of damage to the outer wall of the pipe during installation. They also improve the sealing between the concave side of the semicircular ring 11 and the outer wall of the pipe, preventing external moisture from entering the arc-shaped mounting groove 10 of the semicircular ring 11 and interfering with the normal detection of the humidity sensor 2.

[0042] Both ends of the semicircular ring 11 are provided with ear plates 3, which are integrally formed with the semicircular ring 11. The two semicircular rings 11 are connected and fixed by a connecting assembly, specifically, the connecting assembly includes a connecting block 4 and a bolt and nut. In this embodiment, one end of the semicircular ring 11 is a hinged end and the other end is a movable end. The two ends of the connecting block 4 are respectively hinged to the ear plates 3 at the hinged ends of the two semicircular rings 11, and the axis of the hinge shaft at both ends of the connecting block 4 is parallel to the axis of the semicircular ring 11. The ear plates 3 at the movable ends of the semicircular ring 11 are provided with through holes for bolts to pass through. The bolts pass through the through holes in the ear plates 3 at the movable ends of the two semicircular rings 11, and the nuts are threaded onto the tail end of the bolts and abut against the ear plates 3. This allows the ear plates 3 at the movable ends of the two semicircular rings 11 to be connected and fixed by bolts and nuts. The bolts and nuts restrict the swing of the movable ends of the two semicircular rings 11, which helps to make the detection ring 1 formed by splicing the two semicircular rings 11 more securely installed on the outer periphery of the pipe connection.

[0043] When installing the detection ring 1, swing the two semicircular rings 11 to fit them onto the outer circumference of the adjacent pipe connection to form the detection ring 1. Then, connect and fix the movable end lugs 3 of the two semicircular rings 11 with bolts and nuts to complete the installation of the detection ring 1.

[0044] The implementation principle of Example 1 is as follows: two semicircular rings 11 are spliced ​​together on the outer periphery of the pipe connection to form a detection ring 1, and the two semicircular rings 11 are connected and fixed by a connecting component; when a leak occurs at the pipe connection, the humidity sensor 2 in the arc-shaped mounting groove 10 of the two semicircular rings 11 can promptly feed back a signal to the external equipment, so that maintenance personnel can quickly locate the pipe leak point, making the detection and location of the pipe leak point simpler and more convenient.

[0045] Example 2

[0046] The difference between Example 2 and Example 1 is that:

[0047] Reference Figure 3 and Figure 4 The connecting assembly includes a connecting block 4 and a connecting sleeve 5. In this embodiment, one end of the semicircular ring 11 is a hinged end, and the other end is a movable end. The two ends of the connecting block 4 are respectively hinged to the ear plates 3 at the hinged ends of the two semicircular rings 11, and the axis of the hinge shaft at both ends of the connecting block 4 is parallel to the axis of the semicircular ring 11. The connecting sleeve 5 is fitted onto the ear plates 3 at the movable ends of the two semicircular rings 11 to restrict the separation of the ear plates 3 at the movable ends of the two semicircular rings 11, so as to ensure that the detection ring 1 formed by splicing the two semicircular rings 11 is stably fitted on the outer periphery of the pipe connection.

[0048] When installing the detection ring 1, swing the two semicircular rings 11 to fit them around the outer circumference of the adjacent pipe connection and form the detection ring 1. Then, fit the connecting sleeve 5 into the ear plate 3 at the movable end of the two semicircular rings 11 to complete the installation of the detection ring 1.

[0049] The implementation principle of Example 2 is similar to that of Example 1, so it will not be described again.

[0050] Example 3

[0051] The difference between Example 3 and Example 1 is that:

[0052] Reference Figure 4 and Figure 5 The connecting assembly includes bolts and nuts. The lugs 3 at both ends of the semicircular ring 11 are provided with through holes for bolts to pass through. The bolts pass through the through holes of the lugs 3 at the two ends of the semicircular ring 11 that are close to each other. The nuts are threaded to the tail end of the bolts and abut against the lugs 3. This enables the detection ring 1 formed by the two semicircular rings 11 to be securely fitted on the outer circumference of the pipe connection.

[0053] When installing the detection ring 1, move the two semicircular rings 11 to the outer periphery of the adjacent pipe connection and splice them together to form the detection ring 1. Then, connect and fix the ear plates 3 at the near ends of the two semicircular rings 11 with bolts and nuts to achieve the installation of the detection ring 1.

[0054] In practical use, the assembly of the detection ring 1 can be done manually or in conjunction with a suitable pipeline robot. Specifically, the two semicircular rings 11 of the detection ring 1 can be installed at the end of the pipeline robot's drive mechanism. The pipeline robot then carries the two semicircular rings 11 to the outer perimeter of the designated pipeline connection point and assembles them onto the outer perimeter of the pipeline to form the detection ring 1. After the inspection is completed, the two semicircular rings 11 can be separated by the pipeline robot and moved to the next inspection area.

[0055] The implementation principle of Example 3 is similar to that of Example 1, so it will not be described again.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
