Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection device technology, and in particular to a pipeline inspection device. Background Technology
[0002] In the production of chemical products such as nylon, complex pipeline systems need to be constructed. In the traditional production process, pipeline inspection often relies on manual handheld detectors to detect toxic gases. However, manual inspection is physically demanding and inefficient. In the event of an accidental leak in the pipeline, it can also pose a certain threat to the inspection personnel. In response, this application proposes a pipeline inspection device for detecting leaks of toxic gases in the pipeline, ensuring both the efficiency and safety of the inspection. Utility Model Content
[0003] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a pipeline inspection device. The technical solution includes a track fixedly installed on the workshop ceiling and a host computer located in the factory monitoring room. The track is fitted with a trolley body controlled by the host computer. The trolley body has a mounting plate fixedly connected to its lower end, a lifting device installed in the center of the mounting plate, a lifting rod driven by the lifting device, a connecting rod fixedly connected to the lifting rod, a mounting plate fixedly connected to the connecting rod, and a device controlled by the host computer fixedly connected to the mounting plate. The electric telescopic pole has two guide sleeves symmetrically arranged about its axis, fixedly connected to the mounting plate. Each guide sleeve is slidably connected to a crossbar. The right ends of the two crossbars are fixedly connected to a mounting base. The telescopic end of the electric telescopic pole is fixedly connected to the mounting base. A toxic gas detector is fixedly connected to the mounting base. A detection probe is fixedly installed on the toxic gas detector. A wireless data transmission connected to a host computer is fixedly connected to the upper end of the toxic gas detector. 360-degree cameras electrically connected to the host computer are fixedly connected to the left and right ends of the mounting plate, respectively.
[0004] Preferably, the lifting device includes two vertical rods arranged in a front-to-back correspondence and fixedly connected to the mounting plate. The lower ends of the two vertical rods are fixedly connected to a support plate. A lead screw is arranged between the two vertical rods. The upper and lower ends of the lead screw are fixedly connected to the mounting plate and the support plate, respectively. A motor for driving the lead screw is fixedly connected to the support plate. The motor is controlled by a host computer. The front and rear ends of the lifting rod are slidably connected to the two vertical rods, respectively. The middle part of the lifting rod is threadedly connected to the lead screw.
[0005] Preferably, the front and rear ends of the lifting rod are respectively fixedly connected to sliding sleeves that slide in cooperation with the vertical rods on their corresponding sides, and the middle part of the lifting rod is fixedly connected to a driven screw sleeve that is threadedly connected to the lead screw.
[0006] The beneficial effects of this utility model are: In use, the track is laid on the ceiling of the workshop in the inspection area. The trolley body is controlled by a host computer to move along the track, thus enabling inspection operations and ensuring efficiency and safety. During the movement of the trolley body along the track, the pipeline network condition can be monitored by a 360-degree camera. During the inspection, the lifting device, in conjunction with the electric telescopic rod, can locate the toxic gas detector, allowing the detection probe to be positioned at key locations such as valves or flange connections, and to detect the toxic gas content at these locations. The toxic gas detector transmits the measured data to the host computer wirelessly, and the host computer determines whether a leak has occurred. Simultaneously, during the movement of the trolley body, the detection probe can also detect the toxic gas content along the path, thus detecting any toxic gas leaks. This application has a simple structure, is easy to use, and is highly practical. Attached Figure Description

[0011] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of this utility model will be described in further detail.
[0012] In the first embodiment, the technical solution is as follows: When in use, track 1 is laid on the top of the workshop in the inspection area. The trolley body 2 is controlled by the host computer to move along track 1 (the specific control logic can adopt existing technology, which will not be described in detail here). This allows for inspection operations, ensuring the efficiency and safety of the inspection. During the movement of the trolley body 2 along track 1, the 360-degree camera 15 can monitor the pipeline network. During the inspection, the lifting device 4, in conjunction with the electric telescopic rod 8, can locate the toxic gas detector 12, thereby placing the detection probe 13 at key locations such as valves or flange connections, and detecting the toxic gas content at these locations. The toxic gas detector transmits the measured data to the host computer via wireless data transmission 14, and the host computer determines whether a leak has occurred. At the same time, during the movement of the trolley body 2, the detection probe 13 can also detect the toxic gas content along the path, thereby detecting whether there is a toxic gas leak. This application has a simple structure, is easy to use, and is highly practical.
[0013] In Example 2, based on Example 1, specifically, during use, when it is necessary to inspect pipe valves or other parts at different heights, the toxic gas detector 12 is first positioned at a certain height using the lifting device 4. The motor 19 is then started clockwise by the host computer. The motor 19 is controlled by the host computer, and the specific control method can use existing technology, which will not be described in detail here. The clockwise rotation of the motor 19 drives the lead screw 18, which is rotatably connected between the support plate 17 and the mounting plate 3, to rotate clockwise. The clockwise rotation of the lead screw 18 drives the lifting rod 5 through the driven screw sleeve 21. The front and rear ends of the lifting rod 5 are slidably connected to the vertical rod 16 through the guide sleeve 9. Therefore, the clockwise rotation of the screw will drive the lifting rod 5 to move downward along the vertical rod 16. When the lifting rod 5 moves downward, the connecting rod 6, the mounting plate 7, and the mounting base 11 and other related components will also move downward. Consequently, the toxic gas detector 12 on the mounting base 11 will also move downward. The lifting device 4 adjusts the height of the toxic gas detector 12 through the screw, which facilitates the control of adjustment accuracy. Correspondingly, the reverse rotation of the motor 19 controlled by the host computer can drive the screw 18 to reverse, thereby driving the lifting rod 5 and related components to move upward.
[0014] After the toxic gas detector 12 is moved to an appropriate height, if the detection probe 13 is far from the valve or other part to be detected, the electric telescopic rod 8 is extended by controlling the host computer. The extension of the electric telescopic rod 8 will drive the mounting base 11 to move closer to the part to be detected, thereby improving the accuracy of the detection results. Furthermore, in order to ensure the stability of the electric telescopic rod 8 and the mounting base 11 during long-term use, a crossbar 10 is provided on the mounting base 11 and slidably connected to the guide sleeve 9 to provide support for the mounting base 11 and prevent the weight of one end of the mounting base 11 from affecting the stability of the electric telescopic rod 8. Correspondingly, controlling the retraction of the electric telescopic rod 8 will drive the mounting base 11 to move in the opposite direction and reset. During the process of controlling the extension and retraction of the electric telescopic rod 8 to drive the mounting base 11 to move, the crossbar 10 will also slide synchronously along the guide sleeve 9.
