Technical Field

[0001] This utility model relates to the field of online monitoring device technology, specifically to an online monitoring device for marine LNG consumption. Background Technology

[0002] Online monitoring devices refer to measurement systems and related technologies that are directly installed on the equipment itself and can record and characterize the equipment's operating status in real time. Their general workflow is as follows: First, sensors detect characteristic quantities reflecting the equipment's operating status. Then, the collected information is transmitted to a data processing unit via signal cables or optical fibers. The data processing unit preprocesses and comprehensively analyzes the data, extracting characteristic quantities that accurately reflect equipment faults. Subsequently, this effective data is analyzed and compared with procedures, historical data, etc., to achieve functions such as equipment fault classification and fault location. Finally, alarms are triggered based on preset thresholds, or the development trend of faults and the remaining lifespan of the equipment are assessed and predicted.

[0003] In the monitoring of marine LNG usage, an online monitoring device is also required, specifically an Olympus mass flow meter. This online monitoring device needs to be directly installed on the equipment itself; however, installation presents challenges: it requires manual handling, and both ends of the device must be aligned. Manual handling makes it difficult to precisely control the device's position, further complicating the installation process. Utility Model Content

[0004] The purpose of this invention is to provide an online monitoring device for marine LNG consumption, aiming to solve the problem of existing technologies that also require the use of online monitoring devices, specifically Olympus mass flow meters, in the process of monitoring marine LNG consumption. This online monitoring device needs to be directly installed on the equipment body; however, this online monitoring device presents installation difficulties: it requires manual handling during installation, and both ends of the device must be aligned. During manual handling, it is difficult to accurately control the position of the online monitoring device, thus leading to installation difficulties.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online monitoring device for marine LNG consumption, comprising a measuring tube, with flanges connected to both ends of the measuring tube, a sensor mounted on the surface of the measuring tube, a groove formed on the surface of the measuring tube, a guide rod installed inside the groove, a spring sleeved on the surface of the guide rod, a slider sleeved on the surface of the guide rod, an annular block sleeved on the surface of the measuring tube, and a threaded extrusion bolt threaded through the surface of the annular block.

[0006] In a preferred embodiment of the online monitoring device for marine LNG consumption according to this utility model, the inner ring size of the annular block is the same as the outer ring size of the measuring tube.

[0007] In a preferred embodiment of the online monitoring device for marine LNG consumption according to this utility model, the inner wall of the annular block is connected to the top of the slider, and the annular block can be slidably connected to the measuring tube through the slider.

[0008] In a preferred embodiment of the online monitoring device for marine LNG consumption according to this utility model, the slider can be elastically and telescopically connected to the measuring tube via a spring.

[0009] In a preferred embodiment of the online monitoring device for marine LNG usage according to this utility model, the annular block can be detachably and fixedly connected to the measuring tube by means of extrusion bolts.

[0010] As a preferred embodiment of the online monitoring device for marine LNG consumption according to this utility model, the outer shell surface of the sensor is connected to two symmetrical rectangular blocks, and a mounting column is rotatably connected between the two rectangular blocks. A circular protective plate is fixedly connected to the surface of the mounting column, and a first magnetic block is installed on the inner side wall of the circular protective plate. A fixing block is connected to the outer shell surface of the sensor away from the rectangular blocks, and a second magnetic block is connected to the front end surface of the fixing block.

[0011] In a preferred embodiment of the online monitoring device for marine LNG usage according to this utility model, the circular protective plate can be magnetically connected to the sensor housing via a first magnetic block and a second magnetic block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This marine LNG consumption online monitoring device achieves convenient and efficient installation through the coordinated operation of a chute, guide rod, spring, slider, annular block, and clamping bolt. The operator first rotates the clamping bolt to release the annular block from its fixed position, then pulls the annular block. The annular block moves the slider along the chute. During this movement, the slider compresses the spring and slides along the surface of the guide rod, allowing the annular block to extend beyond the end of the measuring tube. The clamping bolt is then retightened to fix the annular block in its current position. At this point, the annular block can be moved to the connecting pipe of the marine LNG equipment, forming a single-sided auxiliary support. Subsequently, the operator connects the flange at the other end of the measuring tube to the connecting pipe of the marine LNG equipment. This allows the operator to easily control the position of the online monitoring device, effectively avoiding installation difficulties caused by poor positioning, greatly improving installation efficiency, and providing a strong guarantee for the rapid and accurate installation of the marine LNG consumption online monitoring device.

[0014] 2. This marine LNG consumption online monitoring device effectively protects the sensor display screen through the cooperation of rectangular blocks, a circular protective plate, a first magnetic block, a fixed block, a second magnetic block, and a mounting column. The operator flips the circular protective plate, causing the mounting column to rotate between the two rectangular blocks. As the circular protective plate rotates, the first magnetic block gradually approaches the second magnetic block fixed to the fixed block. When the first and second magnetic blocks reach a certain distance, they attract each other, firmly fixing the circular protective plate. At this point, the circular protective plate covers the sensor display screen, providing reliable protection and achieving a good protective effect. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-5The present invention provides the following technical solution: an online monitoring device for marine LNG consumption, comprising a measuring tube 1, with connecting flanges 2 at both ends of the measuring tube 1, a sensor 3 mounted on the surface of the measuring tube 1, a groove 4 opened on the surface of the measuring tube 1, a guide rod 5 installed inside the groove 4, a spring 6 sleeved on the surface of the guide rod 5, a slider 7 sleeved on the surface of the guide rod 5, an annular block 8 sleeved on the surface of the measuring tube 1, and a pressing bolt 9 threaded through the surface of the annular block 8.

[0023] In practical use, the marine LNG consumption online monitoring device consists of a measuring tube 1, a connecting flange 2, and a sensor 3. The sensor is a Proline Promass F 300 Olympus mass flow meter. This Olympus mass flow meter, by directly measuring mass flow rate, perfectly adapts to the physical properties of marine LNG, which are greatly affected by temperature and pressure. Its vibration resistance, low-temperature resistance, and high precision also meet the metering requirements of the complex marine environment. In marine LNG consumption monitoring, it is not only a "metering tool" but also a core node connecting fuel consumption, equipment status, and cost management, providing data support for the efficient and safe operation of the ship.

[0024] It is worth noting that since the marine LNG consumption online monitoring device is connected to the connecting pipeline through the docking flange 2, the device can monitor the marine LNG consumption in real time using the sensor 3 as the marine LNG fuel flows through the connecting pipeline. This captures the key physical parameters of the marine LNG fuel during the transportation process, providing raw data for consumption calculation. This enables continuous, real-time, and dynamic monitoring of the marine LNG fuel consumption throughout the entire process "from storage to consumption." By eliminating data lag through real-time online monitoring, it provides data support for ship fuel management and safety control, making it a key technological equipment for modern green ship operation.

[0025] Preferably, the inner ring size of the annular block 8 is the same as the outer ring size of the measuring tube 1. The inner wall of the annular block 8 is connected to the top of the slider 7, and the annular block 8 can be slidably connected to the measuring tube 1 through the slider 7. The slider 7 can be elastically telescopically connected to the measuring tube 1 through the spring 6. The annular block 8 can be detachably and fixedly connected to the measuring tube 1 through the compression bolt 9.

[0026] In practical use, during the installation of the online monitoring device, the operator first rotates the clamping bolt 9 to release its fixation on the annular block 8. Then, the annular block 8 is pulled, causing the slider 7 to move along the slide groove 4. During the movement, the slider 7 compresses the spring 6 and slides along the surface of the guide rod 5, causing the annular block 8 to extend beyond the end range of the measuring tube 1. Afterward, the clamping bolt 9 is tightened again to fix the annular block 8 in its current position. At this time, the annular block 8 can be moved to the connecting pipe of the marine LNG equipment to form a single-sided auxiliary support. Subsequently, the operator connects the connecting flange 2 at the other end of the measuring tube 1 to the connecting pipe of the marine LNG equipment. This operation method facilitates the operator's control of the position of the online monitoring device, effectively avoiding installation difficulties caused by the inability to control the position, greatly improving installation efficiency, and providing a strong guarantee for the rapid and accurate installation of the marine LNG consumption online monitoring device.

[0027] After completing the connection of one side of the online monitoring device to the marine LNG equipment pipeline, the operator rotates the squeeze bolt 9 to loosen the fixation on the annular block 8. At this time, the spring 6 resets and pushes the slider 7 to move. The slider 7 drives the annular block 8 to reset, thereby exposing the docking flange 2 on the other side of the online monitoring device. Then, the operator reconnects the docking flange 2 to the marine LNG equipment pipeline.

[0028] Preferably, the outer shell of the sensor 3 has two symmetrical rectangular blocks 10 connected to its surface. A mounting post 15 is rotatably connected between the two rectangular blocks 10. A circular protective plate 11 is fixedly connected to the surface of the mounting post 15. A first magnetic block 12 is installed on the inner sidewall of the circular protective plate 11. A fixing block 13 is connected to the outer shell surface of the sensor 3 away from the rectangular blocks 10. A second magnetic block 14 is connected to the front end surface of the fixing block 13. The circular protective plate 11 can be magnetically connected to the outer shell of the sensor 3 through the first magnetic block 12 and the second magnetic block 14.

[0029] In practical use, the operator flips the circular protective plate 11. During the flipping process, the circular protective plate 11 drives the mounting column 15 to rotate within the space defined by the two rectangular blocks 10. As the circular protective plate 11 continues to rotate, the first magnetic block 12 mounted on the circular protective plate 11 gradually moves closer to the second magnetic block 14 fixed on the fixing block 13. When the distance between the first magnetic block 12 and the second magnetic block 14 is shortened to a certain extent, the two attract each other with magnetic force, thereby firmly fixing the circular protective plate 11 in the corresponding position. At this time, the circular protective plate 11 precisely covers the display screen of the sensor 3, building a reliable protective barrier for the display screen and effectively playing a protective role.

[0030] Working principle: When installing the online monitoring device, the operator first rotates the clamping bolt 9 to release its fixation on the annular block 8. Then, the operator pulls the annular block 8, which drives the slider 7 to move along the slide groove 4. During the movement, the slider 7 compresses the spring 6 on one hand and slides along the surface of the guide rod 5 on the other, allowing the annular block 8 to extend beyond the end range of the measuring tube 1. After completing the above operations, the clamping bolt 9 is tightened again to fix the annular block 8 in the current position. At this time, the annular block 8 can be moved to the connecting pipe of the marine LNG equipment to form a single-sided auxiliary support. Then, the operator connects the connecting flange 2 at the other end of the measuring tube 1 to the connecting pipe of the marine LNG equipment. This operation method makes it easy for the operator to control the position of the online monitoring device, effectively avoiding installation difficulties caused by the inability to control the position, greatly improving the installation efficiency, and providing a solid guarantee for the rapid and accurate installation of the marine LNG consumption online monitoring device.

[0031] After one side of the online monitoring device is connected to the connecting pipe of the marine LNG equipment, the operator rotates the squeeze bolt 9 again to loosen the fixation on the annular block 8. At this time, the spring 6 returns to its original position and pushes the slider 7 to move. The slider 7 drives the annular block 8 to return to its original position, thereby exposing the docking flange 2 on the other side of the online monitoring device. Subsequently, the operator reconnects the docking flange 2 to the connecting pipe of the marine LNG equipment.

[0032] Meanwhile, the operator flips the circular protective plate 11. During the flipping process, the circular protective plate 11 drives the mounting column 15 to rotate within the space defined by the two rectangular blocks 10. As the circular protective plate 11 continues to rotate, the first magnetic block 12 mounted on the circular protective plate 11 gradually moves closer to the second magnetic block 14 fixed on the fixing block 13. When the distance between the first magnetic block 12 and the second magnetic block 14 is shortened to a certain extent, the two attract each other with magnetic force, thereby firmly fixing the circular protective plate 11 in the corresponding position. At this time, the circular protective plate 11 just covers the display screen of the sensor 3, building a reliable protective barrier for the display screen and effectively playing a protective role.
