Technical Field

[0001] This utility model relates to the field of marine pipeline auxiliary equipment technology, and in particular to a marine pipeline observation sight with lighting function. Background Technology

[0002] During long-term voyages, the flow status of liquids in pipelines (such as flow velocity, flow stability, presence of air bubbles, and changes in turbidity) is an important indicator of the health of the pipeline system. It is necessary to monitor it in real time and accurately through a sight glass so that staff can detect abnormalities such as pipeline blockage, leakage, media contamination, or equipment failure as soon as possible.

[0003] When using the above technology, the following technical problems were found in the existing technology: First, the sealing performance of the connection between the pipeline and the observation sight is poor, and liquid leakage is prone to occur in the environment of ship turbulence, affecting the safety of ship operation; Second, when observing the liquid in the pipeline, foreign particles in the liquid are easily adsorbed on the inner surface of the observation sight, which is difficult to clean, resulting in a blurred mirror and reducing the observation effect of the staff; Third, some pipelines on the ship are installed in areas with low light, and the existing observation sight lacks effective lighting function, which further affects the accuracy of observation. Therefore, we designed a marine pipeline observation sight with lighting function to provide another technical solution to the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a marine pipeline observation sight with illumination function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A marine pipeline observation sight with illumination function includes an upper pipe and a lower pipe. A sight tube is slidably connected between the upper pipe and the lower pipe. The sight tube has U-shaped sealing grooves at both the top and bottom. The inner sides of the two U-shaped sealing grooves at the top are slidably connected to the upper pipe and the lower pipe, respectively. A sleeve is fitted on the outer side of the sight tube. A sighting port is opened on the outer side of the sleeve. The sighting port is used to observe the liquid flowing in the upper pipe, the lower pipe and the sight tube. A sighting lens is fitted on the inner side of the sighting port.

[0006] The upper connecting flange is mounted on the bottom of the outer side of the upper connecting pipe, and the lower connecting flange is mounted on the top of the outer side of the lower connecting pipe. A connecting mechanism for assembling the flow tube is provided between the upper connecting flange and the lower connecting flange. The connecting mechanism includes a traction rod, a threaded cap, and a sealing assembly. A groove is opened on the outer side of the inner side of the upper connecting flange. The traction rod is rotatably connected to the outer side of the lower connecting flange. The top of the outer side of the traction rod is slidably connected to the groove. A threaded cap is threadedly connected to the top of the outer side of the traction rod. The bottom of the threaded cap resists the upper connecting flange.

[0007] The traction rod, threaded cap, and slot are all in three parts.

[0008] The sealing assembly includes a groove, a connecting threaded sleeve, and a sealing ring. The upper and lower through pipes are rotatably connected to each other at their close ends, and the two connecting threaded sleeves are threadedly connected to the flow tube at their close ends.

[0009] The outer side of the connecting screw sleeve is provided with a driving hole.

[0010] The U-shaped sealing groove is fitted with a sealing ring on its inner side. The upper pipe and the flow tube are sealed together by the sealing ring, and the lower pipe and the flow tube are sealed together by the sealing ring. There are two sealing rings.

[0011] The inner side of the flow tube is provided with a flywheel mechanism for cleaning the flow mirror. The flywheel mechanism includes an impeller, a transmission rod, and a cleaning blade. The transmission rod is rotatably connected to the inner side of the flow tube. The impeller is fixed to the outer side of the transmission rod. A cleaning blade is fixed to one end of the transmission rod. One end of the cleaning blade is slidably connected to the flow mirror.

[0012] The sampling tube is fixed to the outside of the flow tube, and a sealing cap is threaded to the top of the sampling tube.

[0013] The inner side of the viewing port is equipped with a lighting lamp.

[0014] The top of the outer side of the sleeve is fixed with an L-shaped seat, and a recording instrument is assembled at the bottom of the inner side of the L-shaped seat. It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by combining the sight glass and the flow observation port, the staff can observe the liquid status in the pipeline in real time. Combined with the auxiliary lighting effect of the lighting lamp in the dark environment, it is possible to accurately determine whether there are abnormalities such as blockage, leakage, and media contamination in the liquid, so as to take the first-time treatment measures and reduce the risk of equipment failure. The device employs a dual-sealing structure. On the one hand, it achieves initial sealing through the clamping force of the traction rod and the threaded cap. On the other hand, it significantly enhances the sealing performance between the upper pipe, the lower pipe, and the flow pipe by utilizing the meshing action of the sealing ring in the U-shaped sealing groove and the connecting threaded sleeve, effectively preventing liquid leakage and ensuring the safe operation of the pipeline. The flywheel mechanism (including impeller, drive rod, and cleaning blade) can automatically clean foreign particles adsorbed on the inner surface of the observation lens by utilizing the power of liquid flow, eliminating the need for frequent manual disassembly and cleaning, reducing labor costs, and avoiding the problems of decreased observation efficiency and misjudgment caused by contamination of the observation lens. The design of the sampling tube and sealing cap allows staff to safely and conveniently extract liquid samples for testing without affecting the normal flow of the pipeline. Compared with traditional sampling methods, the operation is simpler and can effectively avoid liquid waste or contamination during the sampling process, thus improving the accuracy of the test results. The recording instrument can continuously record the liquid status 24 hours a day, providing comprehensive data support for staff to analyze the liquid health status, troubleshoot potential equipment failures, and formulate maintenance plans, which helps to improve the operation and maintenance management level of pipeline systems.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] As the technical background shows: First, the sealing performance of the connection between the pipeline and the observation sight is poor, which can easily lead to liquid leakage in the turbulent environment of the ship, affecting the safety of ship operation; Second, when observing the liquid in the pipeline, foreign particles in the liquid are easily adsorbed on the inner surface of the observation sight, which is difficult to clean, resulting in a blurred mirror and reducing the observation effect of the staff; Third, some pipelines on the ship are installed in dark areas, and the existing observation sight lacks effective lighting function, which further affects the accuracy of observation.

[0021] Example 1 Please see Figure 1-5 This utility model provides a technical solution: a marine pipeline observation sight with illumination function, including an upper pipe 1 and a lower pipe 2, a sight tube 5 is slidably connected between the upper pipe 1 and the lower pipe 2, and a U-shaped sealing groove 11 is opened at the top and bottom of the sight tube 5. The inner sides of the top and the two U-shaped sealing grooves 11 at the top are slidably connected to the upper pipe 1 and the lower pipe 2 respectively. A sleeve 6 is installed on the outside of the sight tube 5, and a sighting port 7 is opened on the outside of the sleeve 6. An illumination lamp 15 is installed on the inside of the sighting port 7. The sighting port 7 is used to observe the liquid flowing in the upper pipe 1, the lower pipe 2 and the sight tube 5. A sighting lens 8 is installed on the inside of the sighting port 7. When it is necessary to facilitate the observation of liquids in ship pipelines, it is necessary to regularly provide feedback on the health status of the liquids in the pipelines. Therefore, this device needs to monitor the liquids in the pipelines in real time and accurately so that staff can detect abnormalities such as pipeline blockage, leakage, media contamination or equipment failure as soon as possible. Then, the flow tube 5 is installed between the upper pipe 1 and the lower pipe 2, and the liquid in the upper pipe 1, the upper connecting flange 3 and the flow tube 5 are observed in real time through the flow port 7 on the outside of the sleeve 6, so as to improve the recording and feedback of the liquid. Then, the inside of the flow port 7 is illuminated by the light 15, which facilitates the observation of the liquid in the dark environment and prevents the occurrence of judgment errors. An upper connecting flange 3 is fitted at the bottom of the outer side of the upper pipe 1, and a lower connecting flange 4 is fitted at the top of the outer side of the lower pipe 2. A connecting mechanism for assembling the flow tube 5 is provided between the upper connecting flange 3 and the lower connecting flange 4. The connecting mechanism includes a traction rod 21, a threaded cap 22 and a sealing assembly. A slot 12 is opened on the outer side of the inner side of the upper connecting flange 3. The traction rod 21 is rotatably connected to the outer side of the lower connecting flange 4. The top of the outer side of the traction rod 21 is slidably connected to the slot 12. A threaded cap 22 is threadedly connected to the top of the outer side of the traction rod 21. The bottom of the threaded cap 22 resists the upper connecting flange 3. There are three traction rods 21, three threaded caps 22 and three slots 12. Specifically, when the flow tube 5 needs to be assembled, when the flow tube 5 is placed between the upper pipe 1 and the lower pipe 2, the lower pipe 2 is squeezed by rotating the traction rod 21, while the traction rod 21 makes sliding contact with the upper connecting flange 3. At this time, the threaded cap 22 is rotated to pull the traction rod 21 and the lower pipe 2, so that the traction rod 21 and the threaded cap 22 are threadedly engaged, so that the upper pipe 1 and the lower pipe 2 squeeze the flow tube 5. Therefore, the flow tube 5 is sealed and assembled by clamping force, thereby effectively assembling the flow tube 5 between the upper pipe 1 and the lower pipe 2. The sealing assembly includes a slot 12, a connecting screw sleeve 19 and a sealing ring 20. The upper tube 1 and the lower tube 2 are rotatably connected to the ends of the tubes that are close to each other. The ends of the two connecting screw sleeves 19 that are close to each other are threadedly connected to the flow tube 5. A drive hole 23 is provided on the outer side of the connecting screw sleeve 19. A sealing ring 20 is fitted inside the U-shaped sealing groove 11. The upper through pipe 1 and the flow tube 5 are sealed together by the sealing ring 20, and the lower through pipe 2 and the flow tube 5 are also sealed together by the sealing ring 20. There are two sealing rings 20. The connecting sleeve 19 in the sealing assembly is threadedly connected to the flow tube 5. A tool is inserted into the drive hole 23, and then the connecting sleeve 19 is rotated to thread it to the outside of the flow tube 5. The connecting sleeve 19 then drives the upper pipe 1 and the lower pipe 2 to further engage with the flow tube 5. The sealing ring 20 effectively increases the sealing effect between the flow tube 5 and the upper pipe 1 and the lower pipe 2, preventing liquid leakage and ensuring the sealing effect between the upper pipe 1 and the lower pipe 2 and the flow tube 5.

[0022] Example 2 Reference Figures 6-10A marine pipeline observation sight with illumination function, including The inner side of the flow tube 5 is provided with a flywheel mechanism for cleaning the flow mirror 8. The flywheel mechanism includes an impeller 13, a transmission rod 14 and a cleaning blade 18. The transmission rod 14 is rotatably connected to the inner side of the flow tube 5. The impeller 13 is fixed to the outer side of the transmission rod 14. The cleaning blade 18 is fixed to one end of the transmission rod 14. One end of the cleaning blade 18 is slidably connected to the flow mirror 8. Specifically, when the liquid flows through the upper pipe 1, lower pipe 2 and the flow tube 5, and the liquid is observed through the flow mirror 8 in the flow port 7, the liquid flows inside the flow tube 5 for a long time, which will cause foreign particles in the liquid to be adsorbed on the inner surface of the flow mirror 8. Therefore, it greatly affects the efficiency of the staff in observing and detecting the liquid and increases the staff's error judgment. Therefore, the liquid flows between the upper pipe 1, the viewing pipe 5 and the lower pipe 2. At this time, the flowing liquid drives the impeller 13 to rotate, and the impeller 13 drives the transmission rod 14 and the cleaning blade 18 to clean the particles adsorbed on the inner surface of the viewing mirror 8, thereby effectively ensuring the quality and efficiency of the staff's observation and detection of the liquid. A sampling tube 9 is fixed to the outside of the flow tube 5. A sealing cap 10 is threaded to the top of the sampling tube 9. When it is necessary to sample the liquid in the upper pipe 1, the flow tube 5 and the lower pipe 2, the flow mirror 8 is rotated to detach from the sampling tube 9. The liquid in the upper pipe 1, the flow tube 5 and the lower pipe 2 flows from top to bottom. Due to the influence of gravity, the liquid will not spray out from the sampling tube 9. Therefore, the liquid in the sampling tube 9 is extracted by the sampling tool, thereby effectively sampling and testing the liquid in the pipeline, so as to improve the efficiency and accuracy of the operator's testing, and promote the practicality and convenience of the device. An L-shaped seat 17 is fixed to the top of the outer side of the sleeve 6, and a recording instrument 16 is installed at the bottom of the inner side of the L-shaped seat 17. The recording instrument 16 can effectively observe and record the liquid in the pipeline for 24 hours.

[0023] The usage process of the marine pipeline observation sight with illumination function provided by this utility model is as follows: When it is necessary to assemble the flow tube 5, first place the flow tube 5 between the upper pipe 1 and the lower pipe 2, so that the top and bottom U-shaped sealing grooves 11 inside the flow tube 5 are initially connected with the upper pipe 1 and the lower pipe 2 respectively. Then rotate the three traction rods 21 on the outside of the lower connecting flange 4, so that the top of the traction rod 21 slides into the slot 12 on the outside of the upper connecting flange 3. Then rotate the threaded cap 22 on the outside of the traction rod 21, and use the threaded engagement to make the bottom of the threaded cap 22 abut against the upper connecting flange 3, pulling the lower pipe 2 upward, so that the upper pipe 1 and the lower pipe 2 squeeze the flow pipe 5, and achieve initial sealing and clamping. Then, by inserting a tool into the drive hole 23 on the outside of the connecting sleeve 19 at the end of the upper tube 1 and the lower tube 2, the connecting sleeve 19 is rotated to make it threadedly connected to the outside of the viewing tube 5, thereby driving the upper tube 1 and the lower tube 2 to move closer to the viewing tube 5 and engage. At the same time, the two sealing rings 20 inside the U-shaped sealing groove 11 are fully squeezed, which enhances the sealing between the upper pipe 1 and the flow tube 5, and the lower pipe 2 and the flow tube 5 respectively, preventing liquid leakage and completing the complete assembly of the flow tube 5. After the device is assembled, the liquid in the pipeline flows from the upper pipe 1 into the sight pipe 5, and then into the lower pipe 2. The staff can observe the flow status of the liquid in the upper pipe 1, the sight pipe 5 and the lower pipe 2 in real time through the sighting window 8 in the sighting port 7 on the outside of the sleeve 6, and judge whether there is any blockage, leakage or other abnormality. When in a dark environment, turn on the light 15 inside the sight glass 7 to illuminate the area inside the sight glass 7, improve the clarity of liquid observation, and avoid misjudgment due to insufficient light. A recording instrument 16 is installed on the bottom inner side of the L-shaped seat 17 at the top outer side of the sleeve 6. The recording instrument 16 can continuously observe and record the state of the liquid in the pipeline for 24 hours, providing data support for staff to analyze the health status of the liquid and trace abnormalities. When sampling and testing of the liquid inside the pipeline is required, rotate the sealing cap 10 at the top of the sampling tube 9 to detach it from the sampling tube 9. Since the liquid in the upper pipe 1, the viewing pipe 5, and the lower pipe 2 flows from top to bottom, the liquid will not spray out of the sampling tube 9 due to gravity. Workers can then use sampling tools to extract liquid from the sampling tube 9 for further testing and analysis, ensuring the accuracy of liquid detection and observation.
