Description

Technical Field

[0001] This utility model relates to the field of natural gas transmission pipeline technology, specifically a detection device for civil natural gas transmission pipelines. Background Technology

[0002] Natural gas, as a low-pollution fossil fuel, is widely used in people's lives and production under current ecological and environmental requirements. Natural gas is mainly transported via pipelines, and leaks can occur at the connections between pipelines during transportation. Therefore, in actual production, it is necessary to conduct leak tests on the connecting pipelines.

[0003] For example, a natural gas pipeline leakage detection device with announcement number CN210532089U includes a gas collecting assembly installed at the connection of two adjacent pipelines. The gas collecting assembly is sealed to the pipeline. A detection alarm is provided on one side of the gas collecting assembly. The gas collecting assembly is connected to an outlet pipe with the outlet facing the detection alarm. This device solves the problem that existing leakage detection devices are usually installed on one side of the pipeline. Natural gas is lighter than air and easily disperses after leakage. Under the influence of external wind direction and other factors, it is easy to cause inaccurate detection.

[0004] Most of the aforementioned existing technologies improve the overall structure. While existing civilian natural gas pipeline testing devices have solved the problem of inaccurate testing during operation, the test samples obtained after production vary due to the different pipe diameters used in different locations. Moreover, most existing testing devices cannot be adjusted according to the pipe diameter and length. Therefore, in actual testing, unstable pipe installation can easily lead to errors in the test data. Utility Model Content

[0005] The purpose of this invention is to provide a detection device for civil natural gas transmission pipelines, in order to solve the problem mentioned in the background art that most existing natural gas transmission pipeline detection devices cannot be adjusted in actual use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detection device for a civil natural gas transmission pipeline, comprising an adjustable limiting component, a sliding blocking component disposed above the adjustable limiting component, and telescopic testing components slidably mounted on both the left and right sides of the adjustable limiting component; the telescopic testing component includes a bracket, and is adjusted by the internal structure of the adjustable limiting component in conjunction with the internal structure of the telescopic testing component, thereby facilitating quick installation and limiting of pipelines of different lengths and diameters; the adjustable limiting component includes a fixed frame, a threaded rotating rod rotatably mounted inside the fixed frame, a rotating handle fixedly mounted above the threaded rotating rod, and a rotating handle fixedly mounted on both the left and right sides of the fixed frame. The device is equipped with a first connecting plate, inside which rotating blocks are rotatably installed. Each rotating block has a bracket fixedly installed on its side end, and each bracket has an extension plate slidably installed inside. Each extension plate has a second connecting plate fixedly installed on its side end, and inside which connecting rods are rotatably installed. One of the connecting rods has a pressure detector fixedly installed on its side end, and the other connecting rod has a one-way valve fixedly installed on its side end. A valve is rotatably installed above the one-way valve, and the valve is connected to an internal baffle of the one-way valve. By rotating through the internal structure of the adjustable limiting assembly, the device volume is reduced, thereby facilitating adjustment according to the length and diameter of the pipeline and improving the stability of the pipeline during detection.

[0007] Furthermore, a fixed base is fixedly installed on the front side of the fixed frame, and two buffer pads are fixedly installed on the top of the fixed base.

[0008] Furthermore, a collar is fitted on the outer surface of the threaded rod, a clamping frame is fixedly installed on the side end of the collar, and two buffer pads are fixedly installed below the clamping frame.

[0009] Furthermore, the sliding blocking assembly includes a sliding plate, which is slidably mounted on the top of the fixed frame. A straight rack is fixedly mounted on the side end of the sliding plate, and a first spring is provided above the straight rack. One side of the first spring is connected to the straight rack, and the other side is connected to the inner wall of the fixed frame.

[0010] Furthermore, a gear is fixedly installed on the lower outer surface of the rotating armrest, and the gear meshes with a spur rack.

[0011] Furthermore, a rotating block is rotatably mounted inside each of the first connecting plates, a bracket is fixedly mounted on the side end of each rotating block, and an extension plate is slidably mounted inside each bracket.

[0012] Furthermore, a second connecting plate is fixedly installed on the side end of each of the extension plates, and a second spring is provided on the upper and lower sides of each of the extension plates. One side of each second spring is connected to the extension plate, and the other side is connected to the inner wall of the bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This civilian natural gas pipeline inspection device uses a rotating handle to rotate a threaded rod, thereby adjusting the height of the clamping frame to facilitate clamping of pipelines of different diameters. Then, an extension plate is pulled out from the bracket and, together with a second connecting plate and connecting rod, a gas pressure detector and a one-way valve are installed on both sides of the pipeline. This allows the device to be easily adjusted according to the length and diameter of the pipeline during use, thereby improving the stability of the pipeline during inspection and ensuring the accuracy of the inspection data.

[0015] Furthermore, by retracting the extension plate into the bracket and then rotating the bracket along the first connecting plate, the air pressure detector and the one-way valve are rotated to the top of the fixed base. Subsequently, the rotating handle is rotated to push the clamping frame down, and the buffer pad limits the one-way valve and the air pressure detector, so that the device can be easily folded and stored when in use, thus making it convenient to carry.

[0023] 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.

[0024] Example 1: Please refer to Figures 1-6A civilian natural gas pipeline inspection device is disclosed to address the problem that existing pipeline inspection devices are inconvenient to adjust according to the length and diameter of the pipeline during use. The device includes an adjustable limiting component 1, a sliding blocking component 2 above the adjustable limiting component 1, and telescopic testing components 3 slidably mounted on both sides of the adjustable limiting component 1. The telescopic testing components 3 include a bracket 31, and are adjusted by coordinating the internal structure of the adjustable limiting component 1 with the internal structure of the telescopic testing components 3, thus facilitating quick installation and limiting of pipelines of different lengths and diameters. The adjustable limiting component 1 includes a fixed frame 11, which, by rotating its internal structure, reduces the device's volume for easy carrying. A threaded rotating rod 12 is rotatably mounted inside the fixed frame 11, and a rotating handle 13 is fixedly mounted above the threaded rotating rod 12. First connecting plates 14 are fixedly mounted on both sides of the fixed frame 11, and a fixed base 1 is fixedly mounted on the front side of the fixed frame 11. 5. Two buffer pads 16 are fixedly installed above the fixed base 15. A collar 18 is fitted on the outer surface of the threaded rotating rod 12. A clamping frame 17 is fixedly installed on the side end of the collar 18. Two buffer pads 16 are fixedly installed below the clamping frame 17. A rotating block 32 is rotatably installed inside each first connecting plate 14. A bracket 31 is fixedly installed on the side end of each rotating block 32. An extension plate 33 is slidably installed inside each bracket 31. A second connecting plate 33 is fixedly installed on the side end of each extension plate 33. Each extension plate 33 has a second spring 34 on both its upper and lower sides. One side of each second spring 34 is connected to the extension plate 33, and the other side is connected to the inner wall of the bracket 31. Each second connecting plate 35 has a connecting rod 37 rotatably installed inside. One of the connecting rods 37 has a pressure detector 36 fixedly installed on its side end, and another connecting rod 37 has a one-way valve 38 fixedly installed on its side end. A valve 39 is rotatably installed above the one-way valve 38, and the valve 39 is connected to the baffle inside the one-way valve 38.

[0025] like Figures 1-6As shown, the user places the pipe to be tested on the two buffer pads 16 on the fixed base 15, and then pulls the sliding plate 21. At this time, the sliding plate 21 will cause the rack 22 to separate from the gear 24, and at the same time squeeze the first spring 23. Then the user rotates the rotating handle 13, which drives the threaded rod 12 to rotate and cooperate with the limiting position of the fixed frame 11, thereby pushing the collar 18 and the clamping frame 17 to move up and down. With the help of the buffer pads 16 at the bottom of the clamping frame 17, it is convenient to quickly clamp and limit pipes of different diameters. After the limiting is completed, the sliding plate 21 is released. The sliding plate 21 and the rack 22 are reset by the rebound of the first spring 23, so that the rack 22 re-engages with the gear 24. Then the user moves along the... The first connecting plate 14 rotates the bracket 31, and then pulls the extension plate 33 outward to install the air pressure detectors 36 and one-way valves 38 on both sides of the pipeline, thereby facilitating the installation and limiting of pipelines of different lengths. Then, the air supply pipe is connected to the other side of the one-way valve 38, and air is introduced into the pipeline through the air supply pipe in conjunction with the one-way valve 38. As the gas in the pipeline increases, the air pressure displayed on the dial of the air pressure detector 36 gradually increases. After reaching the specified value, the user rotates the valve 39 to seal the inside of the one-way valve 38. Then, the device is left to stand for a period of time, and the value on the dial is observed to detect whether there are any leaks in the pipeline. This allows the device to quickly limit the pipeline of different lengths and diameters during use, thereby improving the stability of the device during use.

[0026] Example 2: Figures 1-3 The technical solution shown, based on Embodiment 1, further discloses the following to address the problem that existing pipeline inspection devices occupy a large area and are inconvenient to carry when not in use: the sliding blocking assembly 2 includes a sliding plate 21, the sliding plate 21 is slidably installed on the top of the fixed frame 11, a rack 22 is fixedly installed on the side end of the sliding plate 21, a first spring 23 is provided above the rack 22, one side of the first spring 23 is connected to the rack 22, and the other side is connected to the inner wall of the fixed frame 11, and a gear 24 is fixedly installed on the lower outer surface of the rotating handle 13, the gear 24 meshing with the rack 22.

[0027] like Figures 1-3As shown, when the user needs to carry the device, the user pushes the extension plate 33 into the bracket 31, then pulls the sliding plate 21 to rotate the rotating handle 13, thereby adjusting the clamping frame 17 and the collar 18 to the highest position. Then, the bracket 31 and other parts are rotated along the first connecting plate 14, so that the one-way valve 38 and the air pressure detector 36 are close to each other and located above the fixed base 15. Then, the rotating handle 13 is rotated again to push the clamping frame 17 down, thereby cooperating with the upper and lower installed buffer pads 16 to buffer, thereby limiting the air pressure detector 36 and the one-way valve 38. Then, the sliding plate 21 is released to limit the rotating handle 13. Finally, the device is lifted along the handle at the back of the fixed frame 11, so that the device can be easily folded and stored when in use, thus making it convenient to carry and use.
