Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically to a device for inspecting the appearance integrity of a furnace bottom gas pipeline. Background Technology

[0002] Gas pipelines are a crucial infrastructure for modern urban energy supply, primarily used to transport combustible gases such as natural gas and coal gas. The gas pipeline at the furnace bottom is essentially a "gas delivery branch pipe," connecting at one end to the main gas network within the building (or the interface after a household gas cylinder / gas meter), and at the other end directly to the "gas inlet valve" of the gas furnace. Ultimately, it delivers the gas to the combustion chamber inside the furnace, where it mixes with air and is ignited by an igniter, providing the energy required for heating (for heating, hot water, or industrial heating). Regular maintenance of gas pipelines is essential for safe gas use. One aspect of this maintenance is inspecting the external integrity of the gas pipeline at the furnace bottom, checking for corrosion, rust, scratches, deformation, and cracks (especially at joints and bends). Metal pipelines should be checked for oxidation of the outer wall due to moisture or chemical substances. However, the current furnace bottom gas pipeline is located close to the ground at the bottom of the furnace, which limits the observation and maintenance angle and makes visual inspection inconvenient. Therefore, this utility model provides a furnace bottom gas pipeline visual integrity inspection device to meet people's needs. Utility Model Content

Equipped with an electric telescopic rod, a rotating rod, friction pads, an inspection housing, a supplementary light, a diffuser, marking cotton blocks, and a camera. The electric telescopic rod and inspection housing work together to allow the camera to easily penetrate the interior of the buried gas pipeline, providing a clearer view of the pipeline's exterior. The supplementary light provides sufficient brightness during shooting, while the diffuser reduces glare, resulting in clearer observation. The marking cotton blocks mark problematic areas for later comparison and to prevent omissions during maintenance. The rotating rod adjusts the angle of the inspection housing, making it easier to adjust the shooting position and angle. The friction pads increase the friction between the rotating rod and the connecting block, providing resistance to the rotation of the rod and ensuring stable rotation, preventing the inspection housing and deflection block from automatically tilting or wobbling.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figure 1-4 As shown, this utility model provides a technical solution: a furnace bottom gas pipeline appearance integrity inspection device, including a fixed base 1, an operating handle 2 installed at one end of the fixed base 1, an electric telescopic rod 3 installed at the bottom of the fixed base 1; a connecting block 4 is connected to the bottom end of the electric telescopic rod 3, a rotating rod 5 is rotatably installed in the middle of the connecting block 4, friction pads 6 are symmetrically installed on the surface of the rotating rod 5 at both sides of the connecting block 4, and a deflection block 7 is fixedly connected to one end of the rotating rod 5; One end of the deflection block 7 is connected to the inspection housing 8. The top two ends of the inspection housing 8 are symmetrically and obliquely installed with supplementary lights 9. The surface of the supplementary lights 9 is covered with a diffuser 10. The top center of the inspection housing 8 is equipped with a marking paint cotton block 11. The top of the inspection housing 8 is symmetrically installed with cameras 12 on both sides of the marking paint cotton block 11. Two friction pads 6 are tightly attached to the two ends of the connecting block 4. The two supplementary lights 9 are obliquely directed towards the top of the two cameras 12. By using the electric telescopic rod 3 and the inspection housing 8 in cooperation, it is easy to insert the camera 12 into the building structure of the buried gas pipeline, so that the appearance of the pipeline can be observed more clearly.

[0017] Furthermore, the supplementary light 9 provides a certain level of brightness during shooting, and the diffuser 10 can reduce glare, making observation clearer. At the same time, the marking cotton block 11 can mark the problematic areas for later comparison and inspection, preventing omissions during subsequent maintenance. The rotating rod 5 can adjust the angle of the inspection housing 8, making it easier to adjust the shooting position and angle. The friction pad 6 increases the friction between the rotating rod 5 and the connecting block 4, providing a certain resistance to the rotation of the rotating rod 5, making the rotation of the rotating rod 5 more stable and preventing the inspection housing 8 and the deflection block 7 from automatically deflecting and shaking.

[0018] A rotating rod 13 is installed at the middle of one end of the fixed base 1. A display 14 is connected to the middle of the rotating rod 13. A fixing block 15 is installed at the middle of one end of the display 14. A locking screw 16 is installed at the middle of the fixing block 15. A positioning screw hole 17 is opened at the top of the operating handle 2. The locking screw 16 and the positioning screw hole 17 are located on the same vertical plane. The signal input terminal of the display 14 is connected to the signal output terminal of the camera 12. The display 14 can be used to directly observe and compare the data captured and inspected on site. The rotating rod 13 provides a certain rotation and folding ability for the display 14, which is convenient for subsequent folding and storage of the display 14. It plays a hidden protection role for its screen, preventing the display 14 from being damaged by impacts from foreign objects due to long-term exposure. The locking screw 16 and the positioning screw hole 17 cooperate with each other to lock and fix the folded display 14, preventing the display 14 from shaking when folded and stored.

[0019] A protective cover 18 is installed on the top of the inspection housing 8. Elastic straps 19 are symmetrically installed on the bottom of the protective cover 18. A positioning cylinder 20 is connected to the bottom of the middle of the protective cover 18. A positioning block 21 is connected to the middle of the two sides of the inspection housing 8. The two sides of the bottom of the protective cover 18 are respectively close to the two sides of the top of the inspection housing 8. The elastic straps 19 are close to the bottom of the inspection housing 8. A positioning through hole is opened in the middle of the positioning block 21. The positioning cylinder 20 is movably inserted into the positioning through hole. The protective cover 18 covers the top of the inspection housing 8, which plays a role in storing and protecting the camera 12 and the supplementary light 9, reducing the probability of damage to the camera 12 by foreign objects during storage. The positioning cylinder 20 and the positioning block 21 work together to position the protective cover 18, so that it will not move left or right. The elastic straps 19 bind and fix the protective cover 18, which improves the installation stability of the protective cover 18.

[0020] The working principle and usage process of this utility model are as follows: First, the staff adjusts the angle of the inspection housing 8 according to the position of the gas pipe at the bottom of the furnace and the angle to be photographed. The rotation of the rotating rod 5 and the connecting block 4 causes the orientation of the inspection housing 8 and the position of the electric telescopic rod 3 to change. The friction pad 6 rubs against the connecting block 4, which improves the stability of the rotating rod 5 and prevents it from easily shaking or deflecting after adjustment. Then, the staff extends the electric telescopic rod 3, inserts the inspection housing 8 into the bottom or back of the gas pipe at the bottom of the furnace, points the camera 12 at the surface of the gas pipe, takes a picture of the gas pipe, and transmits the video information to the monitor 14. The staff can observe the integrity of the pipe's appearance based on the video on the monitor 14, and use the supplementary light 9 to provide brightness to the shooting position, and the soft light cover 10 to reduce the generation of glare, making the shooting clearer. When a suspected damaged or corroded position is observed on the surface of the pipe, the suspected position is marked with a paint-soaked cotton block 11, which will be used for comparison with the image in the next inspection. After the inspection is completed, the electric telescopic rod 3 retracts, and the staff takes the protective cover 18 and stretches the elastic strap 19 so that the protective cover 18 can gradually cover the top of the inspection housing 8 from one side. The elastic strap 19 is located at the bottom of the inspection housing 8. The positioning cylinder 20 is inserted into the positioning block 21 to position the protective cover 18. Then the elastic strap 19 is loosened so that it is tightly attached to the bottom of the inspection housing 8 and the protective cover 18 is tied tightly. The protective cover 18 covers and protects the camera 12, the supplementary light 9 and the marking cotton block 11 to prevent damage during carrying and storage. Next, the monitor 14 is folded so that it rotates around the rotating rod 13 and is placed on the surface of the mounting base 1 with the screen facing down to prevent the monitor 14 from being damaged during carrying or storage. The locking screw 16 is inserted into the positioning screw hole 17 and tightened to fix the monitor 14 and make its folded storage more stable.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
