Description

Technical Field

[0001] This utility model relates to the field of gas pipeline monitoring technology, specifically a remote safety inspection system for gas pipelines in commercial complexes. Background Technology

[0002] Commercial complexes, as building complexes integrating shopping, dining, entertainment and other functions, have complex and widely distributed gas pipeline systems with high usage frequency, resulting in significant safety hazards. Once a gas leak occurs, it will not only waste resources but may also cause serious accidents such as fires and explosions, threatening the lives and property of people. Therefore, it is crucial to conduct regular and efficient safety inspections of gas pipelines.

[0003] Chinese patent discloses a gas leak detection device (authorization announcement number CN218494722U). When using it, depending on the height of the gas pipeline being detected, a telescopic rod can be used. For detecting gas pipelines at lower elevations, the gas leak detector body is held and its probe is positioned at the detection point. For detecting gas pipelines at higher elevations, the telescopic rod is held to raise the gas leak detector body, and its probe is positioned at the detection point. However, the above detection methods largely rely on manual inspection, requiring safety inspectors to manually check each section with the gas leak detector. This is not only inefficient and labor-intensive, but also prone to missed detections and misjudgments due to limitations in personnel experience and the working environment. Especially in commercial complexes, where pipeline layouts are complex, spaces are limited, and there are numerous detection points, traditional methods struggle to achieve comprehensive, real-time, and continuous monitoring. Utility Model Content

[0004] The purpose of this invention is to provide a remote safety inspection system for gas pipelines in commercial complexes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a remote safety inspection system for gas pipelines in commercial complexes, comprising a pipeline, a flow sensor installed on the pipeline, and a bracket fixedly connected to the pipeline. A controller and a wireless transmission module are fixedly connected to the front surface of the bracket, and a data collector is installed on the bracket. The data collector includes a first support plate, a second support plate, and a third support plate. The first support plate, the second support plate, the third support plate, and the fourth support plate are fixedly connected to the bracket. A servo motor is fixedly connected to the first support plate, and a worm gear is fixedly connected to the drive end of the servo motor through the first support plate. A worm wheel meshes with the worm gear, and an adjusting rod is fixedly connected through the inside of the worm wheel. A camera is fixedly connected to the top of the adjusting rod.

[0006] In a preferred embodiment of this invention, one end of the worm gear is rotatably connected to the second support plate via a bearing, and the worm gear and the adjusting rod are perpendicular to each other.

[0007] In a preferred embodiment of this invention, the adjusting rod passes through the third and fourth support plates, and the adjusting rod and the third and fourth support plates are rotatably connected by bearings.

[0008] In a preferred embodiment of this utility model, the first and second support plates are parallel to each other, the third and fourth support plates are parallel to each other, and the third and fourth support plates are of equal size.

[0009] In a preferred embodiment of this invention, the worm gear is located between the third and fourth support plates, and the worm is located between the first and second support plates.

[0010] In a preferred embodiment of this invention, the worm and the adjusting rod are of equal length, and both the worm and the worm wheel are made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Installing flow sensors at pipeline nodes allows for monitoring of gas flow. If the flow rate remains non-zero outside of business hours or after all businesses have closed, it may indicate abnormal gas usage or a leak. In this case, the flow sensor transmits the monitored information to the controller, which then transmits the signal wirelessly to the terminal device, indicating a potential leak risk. The terminal device then uses the wireless transmission module to send control commands to the controller, controlling the servo motor to rotate the worm gear and worm wheel. This, in turn, adjusts the camera's video capture angle and retrieves footage from nearby cameras. When white vapor is observed on the pipeline, a real leak can be remotely confirmed. This system enables remote, real-time, and automated monitoring of gas pipelines in commercial complexes, effectively solving the problems of low efficiency, high labor intensity, and susceptibility to missed detections and misjudgments associated with traditional manual inspection methods. It is particularly suitable for commercial environments with complex pipeline layouts and numerous inspection points, significantly improving the comprehensiveness, accuracy, and response speed of safety inspections.

[0014] 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.

[0015] Please see Figures 1 to 3 This utility model provides a remote safety inspection system for gas pipelines in commercial complexes, including a pipeline 1, a flow sensor 2 installed on the pipeline 1, and a bracket 3 fixedly connected to the pipeline 1. A controller 4 and a wireless transmission module 5 are fixedly connected to the front surface of the bracket 3, and a data collector 6 is installed on the bracket 3. The data collector 6 includes a first support plate 61, a second support plate 62, and a third support plate 63. The first support plate 61, the second support plate 62, the third support plate 63, and the fourth support plate 64 are fixedly connected to the bracket 3. A servo motor 65 is fixedly connected to the first support plate 61. The drive end of the servo motor 65 passes through the first support plate 61 and is fixedly connected to a worm gear 66. A worm wheel 67 meshes with the worm gear 66. An adjusting rod 68 is fixedly connected through the inside of the worm wheel 67. A camera 69 is fixedly connected to the top of the adjusting rod 68.

[0016] Furthermore, one end of the worm gear 66 is rotatably connected to the second support plate 62 via a bearing, which ensures that the worm gear 66 rotates more smoothly and reliably, reducing vibration and offset. The worm gear 66 and the adjusting rod 68 are perpendicular to each other. This arrangement can accurately convert the rotational motion of the worm gear 66 into the pitch rotation of the adjusting rod 68, thereby providing a precise transmission basis for the angle adjustment of the camera 69.

[0017] Furthermore, the adjusting rod 68 passes through the third support plate 63 and the fourth support plate 64. The adjusting rod 68 and the third support plate 63 are rotatably connected by bearings, and the adjusting rod 68 and the fourth support plate 64 are rotatably connected by bearings. The rotatable connection between the adjusting rod 68 and the third support plate 63 and the fourth support plate 64 by bearings provides stable support at both ends, greatly enhancing its stability during rotation and effectively preventing the camera 69 from shaking due to excessive cantilever length, thus ensuring the clarity of image acquisition.

[0018] Furthermore, the first support plate 61 and the second support plate 62 are parallel to each other, and the third support plate 63 and the fourth support plate 64 are parallel to each other. The third support plate 63 and the fourth support plate 64 are of equal size. This symmetrical and parallel layout ensures the accuracy of the relative position between the worm 66 and the adjusting rod 68, so that the transmission between the worm wheel 67 and the worm 66 can always be kept in the best meshing state, ensuring smooth power transmission and precise angle control.

[0019] Furthermore, the worm gear 67 is located between the third support plate 63 and the fourth support plate 64, and the worm 66 is located between the first support plate 61 and the second support plate 62. This spatial layout makes the entire transmission structure very compact, making full use of the installation space inside the first support plate 61, the second support plate 62, the third support plate 63 and the fourth support plate 64, while ensuring that the moving parts do not interfere with each other during operation, making the operation more reliable.

[0020] Furthermore, the worm 66 and the adjusting rod 68 are of equal length. This design makes the overall structure of the collector 6 appear more regular and harmonious. Both the worm 66 and the worm wheel 67 are made of stainless steel, which gives them excellent rust and corrosion resistance, enabling them to adapt to humid environments such as kitchens in commercial complexes. This significantly extends the service life of the equipment and ensures long-term operational reliability.

[0021] Working principle: A flow sensor 2 is installed at a node of pipeline 1 to monitor the gas flow at that node in real time. If the flow sensor 2 detects a non-zero flow value during non-business hours or after all businesses have closed, it indicates a potential abnormal gas usage or leak risk. In this case, the flow sensor 2 transmits the detected abnormal signal to the controller 4. The controller 4 then remotely transmits this signal to an external terminal device via a wireless transmission module 5, allowing staff to promptly detect potential leaks in pipeline 1. Subsequently, the terminal device sends a control command to the controller 4 via the wireless transmission module 5, activating the servo motor 65. The servo motor 65 drives the worm gear 66 to rotate, which in turn drives the meshing worm wheel 67 to rotate. This, in turn, causes the adjusting rod 68, which is fixed inside the worm wheel 67, to rotate. Through this transmission process, the video acquisition angle of the camera 69 fixed to the top of the adjusting rod 68 is precisely adjusted. By retrieving the real-time image from the camera 69 near this node, staff can remotely observe whether there are leakage characteristics such as white mist on the surface of the pipeline 1, thereby visually confirming the alarm information of the flow sensor 2 and determining whether it is a real leak. Through the collaborative work of the flow sensor 2 and the camera 69, the system realizes automated and remote monitoring of whether the gas pipeline 1 is leaking. Compared with the traditional method of safety inspectors using handheld leak detectors to conduct section-by-section visits and inspections, this system significantly improves detection efficiency, reduces labor intensity, and avoids missed detections and misjudgments caused by insufficient human experience or complex environments. It is particularly suitable for commercial complex environments with complex pipeline layouts and numerous inspection points.
