[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. 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.

[0020] Please see Figure 1-4 This utility model provides an embodiment of an SF6 intelligent monitoring device that supports the diagnosis of trace leaks. It may include an SF6 micro-water density sensor 1 and a housing 2. An antenna 7 is installed on the right side of the top of the housing 2. A circuit board 12 is installed at the rear end inside the housing 2. A wireless receiving module 18 is installed on the left side of the front end of the circuit board 12. A control module 13 is installed at the top of the front end of the circuit board 12. An alarm module 15 is installed at the bottom of the control module 13. A display module 14 is installed on the right side of the front end of the circuit board 12. A recording module 16 is installed at the bottom of the display module 14. A wireless transmission module 17 is installed at the bottom of the wireless receiving module 18. A display screen 5 is installed at the front end of the housing 2. An alarm 6 is installed at the top of the housing 2.

[0021] The SF6 micro water density sensor 1 is installed on a three-way pipe. The wireless receiving module 18, control module 13, display module 14, alarm module 15, recording module 16 and wireless transmission module 17 are electrically connected to the circuit board 12 respectively. Bolts are provided at the four corners inside the circuit board 12. The circuit board 12 is installed at the rear end inside the outer casing 2 by bolts.

[0022] Specifically, such as Figure 1 and Figure 2As shown, the SF6 micro-moisture density sensor 1 is installed in a suitable location. The SF6 micro-moisture density sensor 1 can detect many gas parameters of SF6 gas, such as dew point, relative humidity, density, pressure at 20℃, micro-moisture content at 20℃, and dew point at normal pressure. The detected data is transmitted through the wireless transmission module 17 and the wireless receiving module 18, which facilitates remote real-time viewing of monitoring data. The SF6 micro-moisture density sensor 1 can also automatically activate the low-pressure alarm and interlocking device according to preset values ​​or user-given values, providing safety early warning and prevention measures. The alarm 6 can promptly alert and remind staff.

[0023] The antenna 7 is provided with a protective shell 8. A fixing block 11 is fixedly connected to the bottom left side of the protective shell 8. A fixing frame 10 is fixedly connected to the front and rear ends of the top right side of the outer shell 2. Pull plates 20 are provided at the front and rear ends inside the fixing block 11. A spring 24 is fixedly connected between the pull plates 20. A damper 19 is provided inside the spring 24. A limit rod 21 is fixedly connected to the side of the pull plate 20 near the outside. A limit slot 25 is opened inside the fixing frame 10. The fixing block 11 is placed between the fixing frames 10. The limit rod 21 is embedded in the limit slot 25. A sliding groove 23 is fixedly connected to the bottom end inside the fixing block 11. A slider 22 is fixedly connected to the bottom end of the pull plate 20. The slider 22 slides back and forth inside the sliding groove 23.

[0024] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, when transporting the device, pulling the pull plate 20 compresses the spring 24 and pulls the limiting rod 21. Then, the protective shell 8 is fitted onto the outside of the antenna 7 so that the fixing block 11 is embedded inside the fixing frame 10. After it is placed, the pull plate 20 is released. The spring 24, through its own elasticity, causes the limiting rod 21 to be embedded inside the limiting slot 25 to fix the fixing block 11. Fixing the fixing block 11 allows the protective shell 8 to be installed on the outside of the antenna 7 to protect the antenna 7.

[0025] Mounting plates 3 are fixedly connected to the left and right sides of the outer shell 2. Mounting holes 9 are opened at the upper and lower ends inside the mounting plates 3. Movable fixing bolts 4 are installed inside the mounting holes 9. There are two sets of mounting plates 3, and the mounting plates 3 are symmetrically distributed about the vertical center line of the outer shell 2.

[0026] Specifically, such as Figure 1 As shown, when the housing 2 needs to be installed, align the mounting holes 9 inside the mounting plate 3 with the mounting holes 9 at the installation location. After aligning the mounting holes 9, screw the fixing bolts 4 into the mounting holes 9 to fix the mounting plate 3, thereby fixing the housing 2. The SF6 micro-water density sensor 1 not only has a temperature compensation function to ensure the accuracy of micro-water and pressure measurements, but also has excellent anti-interference capabilities and an IP65 protection rating, making it suitable for outdoor and low-temperature environments.

[0027] Working Principle: In use, the mounting holes 9 inside the mounting plate 3 are aligned with the mounting holes 9 at the installation location. After alignment, the fixing bolts 4 are screwed into the mounting holes 9 to fix the mounting plate 3, thus securing the outer casing 2. The SF6 micro-moisture density sensor 1 is installed in a suitable position. The SF6 micro-moisture density sensor 1 can detect various gas parameters of SF6 gas, such as dew point, relative humidity, density, 20℃ pressure, 20℃ micro-moisture content, and atmospheric pressure dew point. The detected data is transmitted through the wireless transmission module 17 and the wireless receiving module 18, facilitating real-time remote monitoring. The SF6 micro-moisture density sensor 1 can also automatically activate a low-pressure alarm and interlocking device according to preset or user-defined values, providing safety warning and prevention measures. The alarm 6 can promptly alert personnel. The SF6 micro-moisture density sensor 1 not only has temperature compensation to ensure the accuracy of micro-moisture and pressure measurements but also possesses excellent anti-interference capabilities, with an IP65 protection rating, suitable for outdoor and low-temperature environments. The recording module 16 can store data, providing large-capacity historical data storage and query functions, and can plot temperature, pressure, and micro-moisture curves based on historical data. It has multiple report generation functions and provides report printing function. When transporting the device, pull the pull plate 20. The pull plate 20 squeezes the spring 24 and pulls the limit rod 21. Then, the protective shell 8 is sleeved on the outside of the antenna 7 so that the fixing block 11 is embedded in the inside of the fixing frame 10. After it is placed, release the pull plate 20. The spring 24 uses its own elasticity to make the limit rod 21 embedded in the inside of the limit slot 25 to fix the fixing block 11. Fixing the fixing block 11 can make the protective shell 8 installed on the outside of the antenna 7 to protect the antenna 7. The model of the SF6 micro water density sensor 1 is GD20 or GDHT20.

[0028] Compared with the prior art, the beneficial effects of this utility model include: the SF6 intelligent monitoring device not only enables timely alarm and antenna protection, but also facilitates the installation and fixation of the device.

[0029] Equipped with an SF6 micro-moisture density sensor, display screen, control module, display module, alarm module, recording module, wireless transmission module, and wireless receiving module, the SF6 micro-moisture density sensor is installed in a suitable location. It can detect numerous gas parameters of SF6 gas, including dew point, relative humidity, density, 20℃ pressure, 20℃ micro-moisture content, and atmospheric pressure dew point. The detected data is transmitted via the wireless transmission and receiving modules, facilitating real-time remote monitoring. The SF6 micro-moisture density sensor can also automatically activate low-pressure alarms and interlocking devices according to preset or user-defined values, providing safety early warning and prevention measures. The alarm can promptly alert personnel.

[0030] The device is equipped with a protective shell, a fixing frame, a fixing block, a damper, a pull plate, a limiting rod, a slider, a slide groove, and a spring. When transporting the device, pulling the pull plate compresses the spring and pulls the limiting rod. Then, the protective shell is fitted onto the outside of the antenna, allowing the fixing block to be embedded inside the fixing frame. After placement, the pull plate is released, and the spring, through its own elasticity, causes the limiting rod to be embedded inside the limiting slot, thus fixing the fixing block. Fixing the fixing block allows the protective shell to be installed outside the antenna, protecting the antenna.

[0031] The SF6 micro-moisture density sensor is equipped with a mounting plate, fixing bolts, and mounting holes. When installing the housing, the mounting holes inside the mounting plate are aligned with the mounting holes at the installation location. After the mounting holes are aligned, the fixing bolts are screwed into the mounting holes to fix the mounting plate, thus securing the housing. The SF6 micro-moisture density sensor not only has a temperature compensation function to ensure the accuracy of micro-moisture and pressure measurements, but also has excellent anti-interference capabilities and an IP65 protection rating, making it suitable for outdoor and low-temperature environments.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
