Description

Technical Field

[0001] This utility model relates to the field of pipeline observation, and in particular to an auxiliary device for pipeline observation. Background Technology

[0002] A pipeline is a device consisting of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, and then flow from high-pressure areas to low-pressure areas in pipelines. Alternatively, the fluid's own pressure or gravity can be used for transport.

[0003] Patent CN213452301U discloses a pipeline observation auxiliary device, comprising: a protective sleeve plate, which can be installed on the outer wall of a pipeline, the protective sleeve plate having a through hole communicating with the pipeline; a sleeve, which is connected to the protective sleeve plate and coaxially arranged with the through hole of the protective sleeve plate, the sleeve being used for inserting a measuring tape into the pipeline; and a water stop valve, which is disposed in the sleeve for opening or closing the sleeve. The pipeline observation auxiliary device provided in this application prevents excessive water pressure inside the pipeline from causing insufficient pressure or overflow through the water stop valve. When observation is required, the water stop valve can be opened, and a measuring tape can be inserted into the pipeline to measure and estimate water level, flow rate, etc. The through hole can also be used to observe the inside of the pipeline and query the range of pipeline faults.

[0004] However, when the measuring tape is inserted into the pipe for measurement, there is a gap between the measuring tape and the sleeve. If the pressure inside the pipe is high, water in the pipe can easily leak out through the sleeve, making it difficult to observe the pipe and reducing the efficiency of pipe observation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pipeline observation auxiliary device.

[0006] The pipeline observation auxiliary device provided by this utility model includes:

[0007] pipeline;

[0008] The casing plate is fixed to the top of the pipe;

[0009] The sleeve is fixed to the top of the casing plate and extends into the pipe;

[0010] The top cover is threaded onto the top of the sleeve;

[0011] A transparent tube, threaded to the top of the cap and extending into the pipe;

[0012] A measuring tape is inserted and connected to a transparent tube;

[0013] A sealing assembly, disposed between the sleeve and the top cover, is used to seal them;

[0014] Multiple limiting components are all located inside the transparent tube to limit the movement of the measuring ruler.

[0015] Preferably, the sealing assembly includes an annular groove formed at the top of the sleeve, an annular plate adapted to the annular groove is fixed at the bottom of the top cover, and an annular rubber pad that abuts against the annular groove is fixed at the bottom of the annular plate.

[0016] Preferably, the limiting component includes a limiting ring fixedly disposed inside the transparent tube, and multiple limiting wheels are rotatably connected to the inner wall of the limiting ring.

[0017] Preferably, a base plate is rotatably connected to the bottom end of the transparent tube, and two connecting rods are hinged to the bottom end of the base plate. The bottom end of each connecting rod is fixed with a scraper that abuts against the bottom end of the inner wall of the tube. Both connecting rods are connected to the base plate through an elastic component.

[0018] Preferably, the elastic component includes a push rod hinged to one side of the connecting rod, a slider hinged to the top of the push rod, and a groove for the slider to slide at the bottom of the base plate, the groove being elastically connected to the slider by a spring.

[0019] Preferably, each of the two connecting rods has a mating positioning block fixed on its opposite side.

[0020] Compared with related technologies, the pipeline observation auxiliary device provided by this utility model has the following beneficial effects:

[0021] 1. The pipeline observation auxiliary device based on the embodiments of this application, when observing the pipeline, firstly, the top cover is screwed onto the sleeve, and the connection between the top cover and the sleeve is sealed by the sealing component. Then, the water stop valve on the sleeve is opened, and then the transparent tube is manually rotated so that the transparent tube extends into the bottom of the inner wall of the pipeline. Then, the measuring tape is inserted into the transparent tube. In this way, with the cooperation of the top cover and the transparent tube, the water in the pipeline can be isolated, preventing the water in the pipeline from leaking due to excessive water pressure, thereby facilitating the observation of the pipeline and improving the observation efficiency of the pipeline.

[0022] 2. Based on the pipeline observation auxiliary device of this application embodiment, when the transparent tube moves downward, it drives the base plate to move downward. When the base plate moves downward, under the resistance and interference at the bottom of the inner wall of the pipeline, it can drive the two connecting rods to open, thereby driving the two scrapers to move to both sides. In this way, under the pushing and scraping of the scrapers, the dirt remaining at the bottom of the inner wall of the pipeline can be scraped and cleaned away, so that the transparent tube can fully contact the bottom of the inner wall of the pipeline, avoiding the gap between the transparent tube and the inner wall of the pipeline due to the residue of dirt. This makes it convenient for the measuring gauge to fully extend into the bottom of the inner wall of the pipeline, thereby facilitating accurate pipeline measurement and improving the accuracy of pipeline measurement.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Please refer to the following: Figures 1 to 5 The pipeline observation auxiliary device includes: a pipeline 1, a protective sleeve 2 fixed at the top of the pipeline 1, a sleeve 3 that penetrates into the pipeline 1 fixed at the top of the protective sleeve 2, a top cover 4 threadedly connected to the top of the sleeve 3, a transparent tube 5 that penetrates into the pipeline 1 threadedly connected to the top of the top cover 4, and a measuring ruler 6 inserted through the transparent tube 5.

[0031] A sealing assembly 7 is disposed between the sleeve 3 and the top cover 4 for sealing them;

[0032] Multiple limiting components 8 are all located inside the transparent tube 5 and are used to limit the measuring scale 6.

[0033] In this embodiment, when observing the pipe 1, the top cover 4 is first screwed onto the sleeve 3, and the connection between the top cover 4 and the sleeve 3 is sealed by the sealing component 7. Then, the water stop valve on the sleeve 3 is opened, and then the transparent tube 5 is manually rotated so that the transparent tube 5 extends into the bottom of the inner wall of the pipe 1. Then, the measuring ruler 6 is inserted into the transparent tube 5. In this way, with the cooperation of the top cover 4 and the transparent tube 5, the water in the pipe 1 can be isolated, preventing the water in the pipe 1 from leaking due to excessive water pressure, thereby facilitating the observation of the pipe 1 and improving the observation efficiency of the pipe 1.

[0034] It should be noted that this application is an improvement on the basis of patent number CN213452301U. The connection structures of the protective sleeve plate 2, sleeve 3, measuring ruler 6, water stop valve and other components in this application have been disclosed in the above-mentioned patent, so this application will not describe them in detail.

[0035] In a further embodiment, such as Figure 3 As shown, the sealing assembly 7 includes an annular groove 71 formed at the top of the sleeve 3, an annular plate 72 adapted to the annular groove 71 is fixed at the bottom of the top cover 4, and an annular rubber pad 73 that abuts against the annular groove 71 is fixed at the bottom of the annular plate 72.

[0036] In this embodiment, when the top cover 4 is screwed onto the sleeve 3, the annular plate 72 rotates and moves downward within the annular groove 71. As the annular plate 72 moves, it drives the movement of the annular rubber pad 73. When the annular rubber pad 73 comes into contact with the inner wall of the annular groove 71, the connection between the top cover 4 and the sleeve 3 can be sealed with the cooperation of the annular rubber pad 73.

[0037] In a further embodiment, such as Figure 4 As shown, the limiting component 8 includes a limiting ring 81 fixedly disposed inside the transparent tube 5, and multiple limiting wheels 82 are rotatably connected to the inner wall of the limiting ring 81.

[0038] In this embodiment, when the measuring scale 6 is inserted into the transparent tube 5, the measuring scale 6 is conveniently limited by the cooperation of the limiting ring 81 and the limiting wheel 82, so as to avoid the measuring scale 6 tilting and affecting the measurement, thus improving the accuracy of the measurement.

[0039] In a further embodiment, such as Figure 5 As shown, a base plate 9 is rotatably connected to the bottom end of the transparent tube 5. Two connecting rods 10 are hinged to the bottom end of the base plate 9. The bottom ends of the two connecting rods 10 are fixed with scrapers 11 that abut against the bottom end of the inner wall of the pipe 1. The two connecting rods 10 are connected to the base plate 9 through elastic components 12.

[0040] In this embodiment, when the transparent tube 5 moves downward, it drives the base plate 9 to move downward. When the base plate 9 moves downward, under the resistance and interference of the bottom end of the inner wall of the pipe 1, it can drive the two connecting rods 10 to open, thereby driving the two scrapers 11 to move to both sides. In this way, under the pushing and scraping of the scrapers 11, the dirt remaining at the bottom end of the inner wall of the pipe 1 can be scraped and cleaned, so that the transparent tube 5 can fully contact the bottom end of the inner wall of the pipe 1, avoiding the gap between the transparent tube 5 and the inner wall of the pipe 1 due to the residue of dirt. This makes it convenient for the measuring gauge 6 to fully extend into the bottom of the inner wall of the pipe 1, thereby facilitating the accurate measurement of the pipe 1 and improving the accuracy of the pipe 1 measurement.

[0041] In a further embodiment, such as Figure 5 As shown, the elastic component 12 includes a push rod 121 hinged to one side of the connecting rod 10, a slider 122 hinged to the top of the push rod 121, and a groove 123 for sliding the slider 122 is provided at the bottom of the base plate 9. The groove 123 is elastically connected to the slider 122 by a spring 124.

[0042] In this embodiment, when the transparent tube 5 moves downward, it drives the base plate 9 to move downward. The base plate 9 drives the connecting rod 10 and the scraper 11 to move downward. When the scraper 11 touches the bottom of the inner wall of the pipe 1, the continued downward movement of the transparent tube 5 drives the two scrapers 11 to move to both sides, thereby causing the two connecting rods 10 to open to both sides. During the opening process of the connecting rods 10, the push rod 121 moves. The push rod 121 drives the slider 122 to compress the spring 124. In this way, with the elastic cooperation of the spring 124, the scraper 11 is always in contact with the bottom of the inner wall of the pipe 1, thus facilitating the cleaning of the bottom of the inner wall of the pipe 1 by the scraper 11. When the transparent tube 5 moves upward, the connecting rod 10 and the scraper 11 can be reset under the elastic action of the spring 124.

[0043] In a further embodiment, such as Figure 5 As shown, each of the two connecting rods 10 has a mating positioning block 13 fixed on its opposite side.

[0044] In this embodiment, before the transparent tube 5 extends into the bottom of the inner wall of the pipe 1, the initial state of the connecting rod 10 is relatively vertical, and the two positioning blocks 13 are in contact with each other. In this way, with the interference of the positioning blocks 13, the connecting rod 10 can open outward and avoid the connecting rod 10 moving inward.

[0045] The working principle of the pipeline observation auxiliary device provided by this utility model is as follows: When observing pipeline 1, first screw the top cover 4 onto the sleeve 3. At this time, the annular plate 72 rotates downward in the annular groove 71. During the movement of the annular plate 72, the annular rubber pad 73 moves. When the annular rubber pad 73 contacts the inner wall of the annular groove 71, the connection between the top cover 4 and the sleeve 3 can be sealed with the cooperation of the annular rubber pad 73. Then, open the water stop valve on the sleeve 3, and then manually rotate the transparent tube 5 so that the transparent tube 5 extends into the bottom of the inner wall of pipeline 1. Then, insert the measuring tape 6 into the transparent tube 5. In this way, with the cooperation of the top cover 4 and the transparent tube 5, the water in pipeline 1 can be isolated, preventing water from entering pipeline 1. Water leakage occurs due to excessive water pressure, facilitating the observation of pipe 1 and improving its observation efficiency. When the transparent tube 5 moves downwards, it causes the base plate 9 to move downwards as well. The downward movement of the base plate 9, due to the resistance and interference at the bottom of the inner wall of pipe 1, causes the two connecting rods 10 to open, thereby moving the two scrapers 11 to both sides. Under the pushing and scraping action of the scrapers 11, the residual dirt at the bottom of the inner wall of pipe 1 can be scraped away, allowing the transparent tube 5 to fully contact the bottom of the inner wall of pipe 1. This prevents the presence of dirt residue and gaps between the transparent tube 5 and the inner wall of pipe 1, facilitating the full insertion of the measuring gauge 6 into the bottom of the inner wall of pipe 1, thus improving the accuracy of pipe 1 measurements.

[0046] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
