Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, and in particular to a monitoring device for leaks in phosphogypsum slurry pipelines. Background Technology

[0002] Phosphogypsum is usually grayish-black or grayish-white. Only a few factories with strict production conditions produce phosphogypsum with fewer impurities and a lighter color, sometimes even white. The main phase of phosphogypsum is calcium sulfate dihydrate. The crystal forms include four types: needle-like, monodisperse plate-like, polycrystalline, and dense. When transporting phosphogypsum slurry, pumps and slurry pipelines are commonly used. Chinese utility model patent, authorized announcement number "CN217843524U", discloses a slurry pipeline leakage detection device, which includes a protective sleeve set outside the slurry pipeline, including an upper protective layer, a lower protective layer, and a partition. The partition divides the upper and lower protective layers into multiple detection spaces. The lower protective layer is formed by a semi-annular shell and two semi-circular side plates connected together.

[0003] The above-mentioned technical solution is simple in structure and easy to use. By timely locating the leakage point of the pipeline, it can effectively curb the further expansion of the leakage accident. However, the above-mentioned technical solution still has certain defects. In actual use, the two protective sleeves are connected by a card block and a card slot. After long-term use, the reliability of the connection between the two protective sleeves cannot be guaranteed. When subjected to external impact or changes in the stress of the pipeline itself, the protective sleeves may be more prone to damage and cracking, which cannot provide a stable protective structure for the slurry pipeline and internal sensors, thereby affecting the normal operation of the entire leakage monitoring system. Therefore, this utility model proposes a new solution. Utility Model Content

This device can solve the problem that the connection between the two protective sleeves is not reliable after long-term use due to the connection between the two protective sleeves via a clip and a slot. When subjected to external impact or changes in the pipeline's own stress, the protective sleeves may be more prone to damage or cracking, and thus cannot provide a stable protective structure for the slurry pipeline and internal sensors, thereby affecting the normal operation of the entire leakage monitoring system.

[0036] Please see Figure 1-9This utility model provides a technical solution: a phosphogypsum slurry pipeline leakage monitoring device, including a phosphogypsum slurry pipeline 1, a lower protective sleeve 2 and an upper protective sleeve 3 fitted on the surface of the phosphogypsum slurry pipeline 1, and a fixing component, which is disposed between the lower protective sleeve 2 and the upper protective sleeve 3. The fixing component includes a locking block 11, which is fixedly connected to the lower end of the upper protective sleeve 3. A locking groove 16 is opened on the surface of the lower protective sleeve 2, and a slider 13 is slidably connected inside the locking groove 16. A limiting block 19 is fixedly connected to the end of the slider 13 near the locking block 11. A limiting groove 20 is opened on the surface of the locking block 11, and the limiting block 19 and the limiting groove 20 are locked together. Two sliding rods 12 are slidably connected inside the slider 13, and both sliding rods 12 are fixed to the inner wall of the locking groove 16. A return spring 14 is fitted on the surface of each of the two sliding rods 12, and the two ends of the two return springs 14 are respectively fixed to the surface of the slider 13 and the inner wall of the locking groove 16. The lower end of the slider 13 away from the locking block 11 is inclined.

[0037] The fixing component also includes a threaded groove 17, which is formed on the surface of the lower protective sleeve 2 and is connected to the interior of the slot 16. The surface of the upper protective sleeve 3 is also provided with a threaded groove 17. The interior of the lower protective sleeve 2 is threaded with a second fixing bolt 18, which is threaded to the two threaded grooves 17.

[0038] The number of fixing components is symmetrically arranged on the lower protective sleeve 2 and the upper protective sleeve 3. Multiple partitions 9 are fixedly connected to the inner wall of the lower and upper protective sleeves 2, and multiple partitions 9 are also fixedly connected to the inner wall of the upper protective sleeve 3.

[0039] Two connecting blocks 15 are fixedly connected to the side of the surface of multiple sliders 13 away from the corresponding card block 11.

[0040] The lower end of the lower protective sleeve 2 is threaded with two acoustic emission sensors 10, and the upper end of the upper protective sleeve 3 is also threaded with two acoustic emission sensors 10. Multiple acoustic emission sensors 10 extend into the interior of the lower protective sleeve 2 and the upper protective sleeve 3 respectively.

[0041] There are two lower protective sleeves 2 and two upper protective sleeves 3, both of which are fitted onto the surface of the phosphogypsum slurry pipe 1.

[0042] A fixing block 4 is provided on the rear side of the phosphogypsum slurry pipeline 1. A first connecting rod 5 is hinged to the upper end of the fixing block 4. A second connecting rod 6 is hinged to the end of the first connecting rod 5 away from the fixing block 4. A connecting plate 7 is hinged to the end of the second connecting rod 6 away from the first connecting rod 5. There are two of each of the first connecting rod 5, the second connecting rod 6 and the connecting plate 7, which are symmetrically arranged on both sides of the fixing block 4. The two first connecting rods 5 and the two second connecting rods 6 are all located on the outside of the lower protective sleeve 2 and the upper protective sleeve 3 and are in contact with the lower protective sleeve 2 and the upper protective sleeve 3.

[0043] Two first fixing bolts 8 are provided on the front side of the fixing block 4, and both first fixing bolts 8 are threadedly connected to the two connecting plates 7.

[0044] When using the device, the outer side of the phosphogypsum slurry pipe 1 is fitted with a lower protective sleeve 2 and an upper protective sleeve 3. These not only protect the pipe from external environmental corrosion, but also provide an installation base for the internal monitoring components. The fixing block 4 on the rear side of the pipe is connected to the connecting plate 7 through the first connecting rod 5 and the second connecting rod 6. The connecting plate 7 is fixed by two first fixing bolts 8. This structure can stabilize the position of the protective sleeve, buffer the vibration and displacement of the pipe, reduce the impact of external impact on the protective sleeve and the pipe, and improve the overall stability.

[0045] The locking block 11 at the lower end of the upper protective sleeve 3 cooperates with the slider 13 in the locking groove 16 on the surface of the lower protective sleeve 2, and the second fixing bolt 18 cooperates with the corresponding thread groove 17. During the process of the second fixing bolt 18 being screwed into the thread groove 17, the inclined surface at the lower end of the slider 13 will be squeezed, so that the limiting block 19 on the slider 13 is engaged with the limiting groove 20 of the locking block 11, thus achieving initial positioning.

[0046] The threaded grooves 17 on the surfaces of the lower protective sleeve 2 and the upper protective sleeve 3 cooperate with the second fixing bolt 18 to further tighten the connection. Multiple fixing components are symmetrically distributed to ensure that the protective sleeves are firmly connected and to prevent leakage and the intrusion of external impurities.

[0047] The fixing block 4 on the rear side of the phosphogypsum slurry pipeline 1 is connected to the connecting plate 7 through the first connecting rod 5 and the second connecting rod 6, and the connecting plate 7 is fixed by two first fixing bolts 8. This structure applies support force to the protective sleeve from the outside of the pipeline, buffers pipeline vibration, displacement and external impact, stabilizes the position of the protective sleeve, reduces friction and collision between the protective sleeve and the pipeline, avoids damage and cracking of the protective sleeve, and extends its service life.

[0048] The connecting block 15 is located on the side of the slider 13 away from the locking block 11. When the protective cover is removed, the connecting block 15 restricts the movement of the slider 13. At the same time, the slider 13 slides on the surface of the slide rod 12 under the action of the return spring 14, which facilitates the separation of the limiting block 19 from the fiber groove 20. This prevents the slider 13 from completely disengaging from the locking groove 16, making it convenient for subsequent reinstallation. When reinstalling, the second fixing bolt 18 is tightened, and the bolt pushes the lower inclined surface of the slider 13, causing the slider 13 to move. The limiting block 19 and the limiting groove 20 are re-engaged, realizing the protective cover is limited and fixed again, simplifying the maintenance process and improving maintenance efficiency.

[0049] The partition 9 on the inner wall of the lower protective sleeve 2 and the upper protective sleeve 3 divides the inside of the protective sleeve into multiple detection areas, narrowing the leakage location range; the upper and lower protective sleeves are respectively threaded to two acoustic emission sensors 10. When the pipeline 1 leaks, the slurry impacts the pipe wall and generates an acoustic emission signal. The sensor 10 receives the signal and converts it into an electrical signal, which is transmitted to the monitoring system for analysis and processing to determine the location and extent of the leak so that timely measures can be taken.

[0050] The acoustic emission sensor 10 operates based on the piezoelectric effect. When a leak occurs in the phosphogypsum slurry pipeline 1, the slurry leakage impacts the pipeline wall and generates stress waves. When these stress waves propagate to the sensor, they cause mechanical deformation of the piezoelectric material inside the sensor. Under mechanical stress, the piezoelectric material converts mechanical energy into electrical energy, generating electrical signals. The characteristics of these electrical signals (such as amplitude, frequency, and duration) are related to the severity and location of the leak. By acquiring, amplifying, and analyzing these electrical signals, it is possible to determine whether a leak has occurred in the pipeline and related information about the leak.

[0051] The acoustic emission sensor 10 is threadedly connected to the lower protective sleeve 2 and the upper protective sleeve 3. This connection facilitates installation and disassembly. When the sensor malfunctions and needs replacement, or when regular maintenance or testing is required, the threaded connection allows technicians to operate quickly and easily. Secondly, the threaded connection ensures tight contact between the sensor and the protective sleeve, ensuring that the sensor can effectively receive acoustic emission signals generated by pipeline leaks. Moreover, this connection method can, to a certain extent, prevent the sensor from loosening or falling off due to vibration, impact, or other factors during operation, ensuring stable sensor operation and improving the accuracy and reliability of leak monitoring.

[0052] Furthermore, the lower protective sleeve 2, upper protective sleeve 3, locking block 11, limiting block 19, and second fixing bolt 18 facilitate the safe and stable operation of the pipeline and the effectiveness of leakage monitoring. The lower protective sleeve 2 and upper protective sleeve 3 are fitted onto the surface of the phosphogypsum slurry pipeline 1 to form a protective barrier against external environmental erosion and provide installation space for internal monitoring components. The locking block 11 and limiting block 19 limit and fix the lower protective sleeve 2 and upper protective sleeve 3. At the same time, the setting of the second fixing bolt 18 further limits and fixes the lower protective sleeve 2 and upper protective sleeve 3, realizing the protection sleeve is limited and fixed again, simplifying the maintenance process and improving maintenance efficiency.

[0053] The lower protective sleeve 2 and the upper protective sleeve 3 are securely connected, providing a stable installation base for the acoustic emission sensor 10. The acoustic emission sensor 10 is threadedly connected to the lower protective sleeve 2 and the upper protective sleeve 3, which facilitates installation, disassembly and maintenance, and ensures close contact between the sensor and the lower protective sleeve 2 and the upper protective sleeve 3. This allows it to effectively receive acoustic emission signals generated by pipeline leaks, help determine the location and extent of the leak, provide a basis for timely handling of leak problems, and ensure the normal operation of the entire leak monitoring system.

[0054] Structural Description: Phosphogypsum slurry pipeline 1: It is the carrier for transporting phosphogypsum slurry. In the entire device, it is the object to be protected and monitored, providing the basis for the subsequent structures to function.

[0055] Lower protective sleeve 2 and upper protective sleeve 3: They are fitted onto the surface of phosphogypsum slurry pipeline 1 to form a protective barrier against external environmental erosion and to provide an installation base for internal monitoring components; the two work together with other structures to ensure the safe and stable operation of the pipeline and improve its service life.

[0056] Fixing block 4, first connecting rod 5, second connecting rod 6, connecting plate 7, and first fixing bolt 8: The fixing block 4 is located on the rear side and is connected to the connecting plate 7 through the first connecting rod 5 and the second connecting rod 6. The first fixing bolt 8 fixes the connecting plate 7. This structure applies support force to the lower protective sleeve 2 and the upper protective sleeve 3 from the outside of the pipeline, buffering pipeline vibration, displacement and external impact, stabilizing the position of the protective sleeve, reducing friction and collision between the protective sleeve and the pipeline, avoiding damage and cracking of the protective sleeve, extending the service life of the protective sleeve and the pipeline, and improving overall stability.

[0057] The components include: a locking block 11, a limiting block 19, a limiting groove 20, a slider 13, a sliding rod 12, and a return spring 14. The locking block 11 is fixed to the lower end of the upper protective sleeve 3 and cooperates with the slider 13 in the locking groove 16 of the lower protective sleeve 2. The limiting block 19 on the slider 13 engages with the limiting groove 20 of the locking block 11, achieving the initial positioning of the lower protective sleeve 2 and the upper protective sleeve 3. The sliding rod 12 and the return spring 14 keep the slider 13 stable and have the ability to automatically reset, enhancing the connection stability and preventing the protective sleeve connection from loosening.

[0058] Threaded groove 17 and second fixing bolt 18: Both the lower protective sleeve 2 and the upper protective sleeve 3 are provided with threaded groove 17, and the second fixing bolt 18 is engaged with the threaded groove 17. During installation, the second fixing bolt 18 is screwed into the threaded groove 17, which presses the lower end of the slider 13 and pushes the slider 13 to make the limiting block 19 tightly engage with the limiting groove 20, further securing the connection between the lower protective sleeve 2 and the upper protective sleeve 3. The multiple symmetrically distributed fixing components enhance the firmness of the protective sleeve connection from all directions, preventing leakage and the intrusion of external impurities.

[0059] Connecting block 15: Located on the side of slider 13 away from locking block 11, it restricts the movement of slider 13 when the protective cover is removed. It works with the return spring 14 to allow slider 13 to slide on slide rod 12, which facilitates the disengagement of limiting block 19 from limiting groove 20 and prevents slider 13 from completely disengaging from locking groove 16. During reinstallation, it is convenient to push slider 13 by turning the second fixing bolt 18 to re-engage limiting block 19 with limiting groove 20, simplifying the maintenance process and improving maintenance efficiency.

[0060] Partition 9: Multiple partitions 9 are fixed to the inner walls of both the lower protective sleeve 2 and the upper protective sleeve 3, dividing the interior of the protective sleeve into multiple detection areas, reducing the leakage location range, improving the accuracy and efficiency of leakage monitoring, and facilitating the rapid determination of the leakage location;

[0061] Acoustic emission sensor 10: Two acoustic emission sensors 10 are threadedly connected to the lower end of the lower protective sleeve 2 and the upper end of the upper protective sleeve 3 respectively; based on the piezoelectric effect, when the pipeline 1 leaks, the slurry impacts the pipe wall and generates an acoustic emission signal. The sensor 10 receives the signal and converts it into an electrical signal, which is transmitted to the monitoring system for analysis and processing to determine the location and extent of the leak, providing a basis for timely handling of the leak and ensuring the normal operation of the entire leak monitoring system; the threaded connection facilitates installation, disassembly and maintenance, ensures tight contact between the sensor and the protective sleeve, effectively receives the acoustic emission signal, and prevents loosening or falling off due to vibration, impact and other factors, thereby improving the accuracy and reliability of leak monitoring.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
