This requires workers to use specialized tools to clean the silt from the pipeline surface beforehand, which not only increases the workload of the workers but also affects the efficiency of pipeline inspection.

[0004] Therefore, a rapid leak location device for pipelines is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, when using a locator to detect leaks in pipelines, the pipelines are located underground and their surfaces are often covered with silt. This requires workers to use specialized tools to clean the silt from the pipeline surface beforehand, which not only increases the workload of the workers but also affects the efficiency of pipeline inspection. This invention proposes a rapid pipeline leak location device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The pipeline leak point quick locator of this utility model includes a mounting frame, a pair of mounting rings are detachably connected to the bottom of the mounting frame, and sliding plates are slidably connected to both outer sides of the mounting frame. A detector and a cleaning plate are respectively fixedly connected to the bottom of the two sliding plates. A positioning component is provided inside the mounting frame, and a transmission component is provided inside the mounting frame. The positioning component includes a mounting plate. Mounting plates are symmetrically slidably connected to both inner sides of the mounting frame. Rollers are equidistantly provided on both inner sides of the mounting frame, and rollers are provided on the inner sides of both sets of mounting plates.

[0007] Preferably, the transmission assembly includes a first gear and a transmission unit.

The outer sides of the mounting frame are each fixedly connected to a first motor via a fixing block. The output ends of the two first motors are respectively fixedly connected to the corresponding rotating shafts. The outer sides of the two mounting plates are provided with teeth. The two sets of first gears extend into the interior of the mounting frame and are respectively fixedly connected to the corresponding mounting plates via teeth. The two slide plates can be rotated via the transmission unit.

[0008] Preferably, the transmission unit includes a gear ring, which is fixedly connected to the bottom two sides of the mounting frame and the top outer side of the two mounting rings respectively. The bottom side of each of the two slide plates is rotatably connected to a second gear through a limiting plate. The second gear meshes with the corresponding gear ring.

This allows the cleaning plate to first clean the sludge on the outer wall of the pipeline, and then the detector to spiral forward and detect the pipeline through the air inlet. This avoids the problem that a lot of sludge on the outer wall of the pipeline can affect the movement of the device and the detection accuracy of the detector. It also avoids the trouble of manually cleaning the sludge on the outer wall of the pipeline with external tools before pipeline detection. This effectively improves the accuracy and efficiency of pipeline detection and greatly reduces the workload of the staff. Furthermore, this device can first be positioned on the outside of the pipeline with the mounting frame and mounting plate, and then the mounting ring can be stably installed.

[0024] 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.

[0025] Example 1

[0026] Please see Figure 1-5As shown, the pipeline leak locator includes a mounting frame 1. A pair of mounting rings 4 are detachably connected to the bottom of the mounting frame 1. Slide plates 5 are slidably connected to both outer sides of the mounting frame 1. A detector 6 and a cleaning plate 7 are respectively fixedly connected to the bottom of the two slide plates 5. A positioning component and a transmission component are installed inside the mounting frame 1. The positioning component includes mounting plates 2. Mounting plates 2 are symmetrically slidably connected to both inner sides of the mounting frame 1. Rollers 3 are equidistantly arranged on both inner sides of the mounting frame 1. Rollers 3 are also provided on the inner sides of both sets of mounting plates 2. The transmission component includes a first gear 8 and a transmission unit. The first gear 8 is symmetrically rotatably connected to both outer sides of the mounting frame 1 via rotating shafts. A first motor is fixedly connected to both outer sides of the mounting frame 1 via fixing blocks. 9. The output ends of the two first motors 9 are fixedly connected to the corresponding rotating shafts. The exterior of the two mounting plates 2 are provided with teeth 18. The two sets of first gears 8 extend into the interior of the mounting frame 1 and are fixedly connected to the corresponding mounting plates 2 through the teeth 18. The two slide plates 5 can be rotated through the transmission unit. The transmission unit includes a gear ring 10. The gear ring 10 is fixedly connected to the bottom sides of the mounting frame 1 and the top outer side of the two mounting rings 4. The bottom side of the two slide plates 5 is rotatably connected to the second gear 11 through the limiting plate. The second gear 11 meshes with the corresponding gear ring 10. The bottom of the two slide plates 5 is fixedly connected to the second motor 12 through the fixing block. The output ends of the two second motors 12 are fixedly connected to the corresponding second gear 11.

[0027] During operation, the mounting bracket 1 is first placed on top of the pipe and supported by rollers 3, so that the air inlet 17 at the bottom of the detector 6 is close to the pipe and the scraper 19 and bristles 20 at the bottom of the cleaning plate 7 are in contact with the outer wall of the pipe. Then, the two first motors 9 are started, and the two sets of first gears 8 are driven to rotate synchronously through the two rotating shafts. The multiple first gears 8 drive the two sets of mounting plates 2 to slide outward from the mounting bracket 1 through the meshing relationship. The two sets of mounting plates 2 drive the inner rollers 3 to move towards the bottom of the pipe, and the rollers 3 on the inner side of the mounting bracket 1 are used to position and clamp the pipe. Then, the two mounting rings 4 are installed on the mounting bracket 1 through the two sets of mounting blocks 15 and bolts 16, and the two sets of gear rings 10 are spliced. After installation, the mounting bracket 1 is pushed towards the cleaning plate 7 from the outside of the pipe through the multiple rollers 3, and the two second motors 12 and the detector 6 are started at the same time. The two second motors 12 drive the corresponding second gears 11 to rotate, so that the second gears 11 drive the corresponding sliding plates through the meshing relationship. 5. The device rotates around the center of the pipe, causing the detector 6 and the cleaning plate 7 to rotate around the pipe. This allows the cleaning plate 7 to first clean the sludge on the outer wall of the pipe, and then the detector 6 to spiral forward and inspect the pipe through the air inlet 17. This effectively avoids the problem that a lot of sludge on the outer wall of the pipe can affect the movement of the device and the detection accuracy of the detector 6. It also avoids the trouble of manually cleaning the sludge on the outer wall of the pipe with external tools before inspection. This effectively improves the accuracy and efficiency of the device in inspecting pipes and greatly reduces the workload of the staff. Furthermore, the device can be positioned outside the pipe first with the mounting bracket 1 and the mounting plate 2, and then the mounting ring 4 can be installed stably. This avoids the problem that it is difficult to accurately align the mounting ring 4 with the mounting bracket 1 when directly installing, which makes it difficult to achieve rapid installation. This further improves the installation efficiency of the device and thus improves the efficiency of leak detection in pipes.

[0028] Among them, the inner sides of the mounting frame 1 are fixedly connected with limit sleeves 13 at equal intervals, the inner sides of the two sets of mounting plates 2 are fixedly connected with limit sleeves 13, multiple rollers 3 are slidably connected to the inner side of the corresponding limit sleeves 13, and springs 14 are provided inside the multiple limit sleeves 13 and on one side of the rollers 3. Mounting blocks 15 are symmetrically fixedly connected to the bottom sides of the mounting frame 1 and the top of the two mounting rings 4. Bolts 16 are symmetrically threaded inside the two sets of mounting blocks 15. An air inlet 17 is installed at the bottom of the detector 6. The outer sides of the slide plate 5 and the cleaning plate 7 are arc-shaped structures.

[0029] Through the above technical solution, the adaptive elastic force of the spring 14 inside the limiting sleeve 13 can push the roller 3 to always fit against the outer wall of the pipe, thereby enabling better positioning of the mounting bracket 1 and making it easier to push the mounting bracket 1.

[0030] Example 2

[0031] Please see Figure 6 As shown in the first embodiment, as another implementation of the present invention, a scraper 19 is provided on one side of the bottom of the cleaning plate 7, and bristles 20 are provided on the side of the bottom of the cleaning plate 7 near the scraper 19.

[0032] During operation, the scraper 19 can first scrape the sludge on the outer wall of the pipe, and then the brush 20 can brush away the remaining sludge, which can quickly complete the cleaning work and improve the cleaning and inspection efficiency of the pipe.

[0033] Working principle: First, the mounting bracket 1 is placed on top of the pipe and supported by rollers 3, so that the air inlet 17 at the bottom of the detector 6 is close to the pipe and the scraper 19 and bristles 20 at the bottom of the cleaning plate 7 are in contact with the outer wall of the pipe. Then, the two first motors 9 are started, and the two shafts drive the two sets of first gears 8 to rotate synchronously. The multiple first gears 8 drive the two sets of mounting plates 2 to slide outward from the mounting bracket 1 through the meshing relationship. Then, the two sets of mounting plates 2 drive the inner rollers 3 to move towards the bottom of the pipe. With the help of the inner rollers 3 of the mounting bracket 1, the pipe is positioned and clamped. Then, the two mounting rings... 4. The mounting bracket 1 is installed with two sets of mounting blocks 15 and bolts 16, and the two sets of gear rings 10 are spliced ​​together. After installation, the mounting bracket 1 is pushed towards the cleaning plate 7 from the outside of the pipe by multiple rollers 3. At the same time, the two second motors 12 and the detector 6 are started. The two second motors 12 drive the corresponding second gears 11 to rotate, so that the second gears 11 drive the corresponding slide plate 5 to rotate around the center of the pipe through the meshing relationship. This causes the detector 6 and the cleaning plate 7 to rotate around the pipe. Thus, the cleaning plate 7 first cleans the sludge on the outer wall of the pipe, and the detector 6 then cleans the sludge on the outer wall of the pipe through the air inlet 17. The purpose of spiraling the pipeline during inspection is to effectively avoid the problem of excessive sludge adhering to the outer wall of the pipeline affecting the advancement of the device and the detection accuracy of the detector 6. It also avoids the hassle of manually cleaning the sludge from the outer wall of the pipeline with external tools before inspection, effectively improving the accuracy and efficiency of the device's pipeline inspection and significantly reducing the workload of personnel. Furthermore, the device can be first positioned on the outside of the pipeline using the mounting bracket 1 and mounting plate 2, and then the mounting ring 4 can be stably installed, avoiding the difficulties caused by direct installation due to positioning challenges. To address the issue of difficulty in quickly aligning the mounting ring 4 with the mounting bracket 1, this device further improves installation efficiency, thereby enhancing leak detection efficiency in pipelines. The adaptive elasticity of the spring 14 within the limiting sleeve 13 ensures the roller 3 remains in contact with the outer wall of the pipeline, allowing for better positioning of the mounting bracket 1 and easier, effortless pushing. The scraper 19 first removes sludge from the outer wall of the pipeline, followed by brushing with bristles 20 to remove residual sludge, quickly completing the cleaning process and improving both pipeline cleaning and detection efficiency.
