Abstract
Description
Technical Field
[0001] This application relates to the field of density and moisture monitoring technology, and more particularly to an SF6 density and moisture monitoring device. Background Technology
[0002] The main function of the density and moisture monitoring device is to monitor the density and moisture content of SF6 gas in real time, ensuring the safe operation and efficient maintenance of the equipment. Through real-time monitoring, changes in the moisture content and density of SF6 gas can be detected in a timely manner, ensuring that the insulation performance and operating status of the equipment are kept at their best.
[0003] However, existing SF6 density moisture monitoring devices may be subjected to mechanical vibration and external impact during operation, which may cause equipment damage, sensor damage, or distortion of measurement data. During installation, the sealing directly affects the measurement accuracy and operational safety of the device. Poor sealing may lead to gas leakage, affecting the accuracy of monitoring data, and may even cause equipment failure. Utility Model Content
[0004] In view of the above problems, this application provides an SF6 density moisture monitoring device to solve the problems that existing SF6 density moisture monitoring devices may be subject to mechanical vibration and external impact during operation, which may cause equipment damage, sensor damage or measurement data distortion. During installation, the sealing directly affects the measurement accuracy and operational safety of the device. Poor sealing may lead to gas leakage, affecting the accuracy of monitoring data, and may even lead to equipment failure.
[0005] This application provides an SF6 density moisture monitoring device. It includes a main body, a display screen mounted on one side of the main body, a first protective frame movably mounted on one side of the outer wall of the main body, a limit groove on one side of the first protective frame, a mounting block movably fitted inside the limit groove, the mounting blocks symmetrically mounted on one side of a second protective frame, and a through hole at the top of each mounting block. A pull rod is movably fitted on one side of the first protective frame.
[0006] With the above solution, after pulling the lever to retract it into the groove, the mounting block on one side of the second protective frame is movably embedded into the limiting groove. Then, by pushing the lever to movably embed it into the through hole on one side of the mounting block, the mounting block is fixed in the limiting groove. This allows the first protective frame to be fixed to one side of the second protective frame. The first and second protective frames provide external protection for the main body of the monitor, reducing the risk of damage to the equipment caused by external factors, which could affect the accuracy and reliability of the monitoring.
[0007] In some embodiments, a pad is fixedly connected to the outer wall of the pull rod, the pad is movably sleeved inside the groove, the groove is opened on one side of the first protective frame, and a telescopic spring is fixedly installed on the top of the pad, the telescopic spring is movably sleeved on the outer wall of the pull rod.
[0008] With the above solution, when the pull rod is pulled, it also causes the pad to slide in the groove, which in turn causes the telescopic spring to retract. When there is no pulling force, the telescopic spring can be used to reset the pad and pull rod, improving the flexibility of installation.
[0009] In some embodiments, a transparent window is provided on one side of the first protective frame.
[0010] With the above solution, the first and second protective frames are movably installed on the outer wall of the monitoring instrument body for protection, while the transparent window facilitates observation of the display screen.
[0011] In some embodiments, an interface is provided on one side of the main body of the monitor, a mounting groove is provided on one side of the interface, a connecting pipe is installed on one side of the mounting groove, a reset spring is installed at the bottom of the inner wall of the mounting groove, and a sealing block is fixedly installed on one side of the reset spring.
[0012] The above method allows for flexible installation by flexibly embedding the connecting pipe into the mounting groove. As the connecting pipe moves within the groove, it pushes the sealing block, which in turn causes the return spring to retract. The return spring's elasticity allows the sealing block to return to its original position, fitting against the side where the connecting pipe is embedded. This sealing block's sealing performance reduces gaps in the mounting groove and improves the seal after installation.
[0013] In some embodiments, a first limiting ring is movably mounted on the outer wall of the interface, a second limiting ring is hinged to one side of the first limiting ring, a bolt is threaded onto one side of the first limiting ring, and a sealing strip is fixedly mounted on the inner walls of the first and second limiting rings.
[0014] The above solution involves placing the first and second limiting rings at the connection between the interface and the mounting groove. By tightening the bolts, the first and second limiting rings are fixed in place, while the sealing strip on the inner wall completely fits the connection between the interface and the mounting groove. The sealing strip's sealing performance can seal the connection, preventing gas leakage and ensuring the airtightness of the connection.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. After pulling the lever to retract it into the groove, the mounting block on one side of the second protective frame is movably embedded into the limiting groove. Then, the lever is pushed to move into the through hole on one side of the mounting block, so that the mounting block is fixed in the limiting groove. The first protective frame can be fixed to one side of the second protective frame. The first and second protective frames provide external protection for the main body of the monitor, reducing the possibility of damage to the equipment caused by external factors, which may affect the accuracy and reliability of monitoring. External factors may also cause sensor damage or distortion of measurement data, thereby affecting the accuracy of monitoring results and extending the service life of the equipment.
[0017] 2. The connecting pipe is flexibly installed by being embedded into the mounting groove. The return spring can push the sealing block to move back to its original position, pushing the sealing block to fit against the side of the connecting pipe that is embedded. The sealing block, the first limit ring and the second limit ring form a fixed state, reducing the gaps between the connecting pipe and the joint in the mounting groove, improving the sealing performance after installation, increasing the prevention of gas leakage, ensuring the sealing performance of the connection, and avoiding gas leakage that may be caused by poor sealing, which could affect the accuracy of monitoring data or even cause equipment failure.

[0032] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0033] This application provides an embodiment of an SF6 density moisture monitoring device. For example... Figures 1-6 As shown, the device includes a main body 1 of the monitor, a display screen 2 installed on one side of the main body 1, a first protective frame 3 movably installed on one side of the outer wall of the main body 1, a limit groove 4 opened on one side of the first protective frame 3, an installation block 5 movably sleeved inside the limit groove 4, the installation block 5 symmetrically installed on one side of the second protective frame 6, a through hole 7 opened at the top of the installation block 5, and a pull rod 8 movably sleeved on one side of the first protective frame 3.
[0034] After pulling the lever 8 to retract it into the groove 10, the mounting block 5 on one side of the second protective frame 6 is movably embedded into the limiting groove 4. Then, the lever 8 is pushed to movably embed into the through hole 7 on one side of the mounting block 5, so that the mounting block 5 is fixed in the limiting groove 4. The first protective frame 3 can be fixed on one side of the second protective frame 6. The first protective frame 3 and the second protective frame 6 provide external protection for the main body 1 of the monitoring instrument, reducing the possibility of damage to the equipment caused by external factors, which may affect the accuracy and reliability of the monitoring.
[0035] In the technical solution of this application embodiment, a pad 9 is fixedly connected to the outer wall of the pull rod 8. The pad 9 is movably sleeved inside the groove 10. The groove 10 is opened on one side of the first protective frame 3. A telescopic spring 11 is fixedly installed on the top of the pad 9. The telescopic spring 11 is movably sleeved on the outer wall of the pull rod 8.
[0036] When the pull rod 8 is pulled, it also causes the pad 9 to slide in the groove 10, which in turn causes the telescopic spring 11 to retract. When there is no pulling force, the telescopic spring 11 can drive the pad 9 and the pull rod 8 to reset and move by means of its elasticity, thus improving the flexibility of installation.
[0037] In the technical solution of this application embodiment, a transparent window 12 is provided on one side of the first protective frame 3.
[0038] When the first protective frame 3 and the second protective frame 6 are movably installed on the outer wall of the main body 1 of the monitoring instrument, the transparent window 12 facilitates the observation of the display screen 2.
[0039] In the technical solution of this application embodiment, the main body 1 of the monitoring instrument has an interface 13 on one side, an installation groove 14 on one side of the interface 13, a connecting pipe 15 on one side of the installation groove 14, a reset spring 16 on the bottom of the inner wall of the installation groove 14, and a sealing block 17 fixedly installed on one side of the reset spring 16.
[0040] The connecting pipe 15 is flexibly installed by being movably embedded into the mounting groove 14. As the connecting pipe 15 moves within the mounting groove 14, it pushes the sealing block 17, which in turn causes the return spring 16 to retract. Through the extensibility of the return spring 16, the sealing block 17 can be pushed to return to its original position, thus adhering to the side where the connecting pipe 15 is embedded. The sealing performance of the sealing block 17 reduces the gaps in the mounting groove 14 and improves the sealing performance after installation.
[0041] In the technical solution of this application embodiment, a first limiting ring 18 is movably installed on the outer wall of interface 13, a second limiting ring 19 is hinged to one side of the first limiting ring 18, a bolt 20 is threaded onto one side of the first limiting ring 18, and a sealing strip 21 is fixedly installed on the inner wall of the first limiting ring 18 and the second limiting ring 19.
[0042] The first limiting ring 18 and the second limiting ring 19 are moved to the connection between the interface 13 and the mounting groove 14. The bolt 20 is then tightened to fix the first limiting ring 18 and the second limiting ring 19 in a fixed state. The sealing strip 21 on the inner wall is completely fitted to the connection between the interface 13 and the mounting groove 14. The sealing strip 21 can seal the connection, increase the prevention of gas leakage, and ensure the sealing of the connection.
