Description

Technical Field

[0001] This utility model relates to the technical field of monitoring and alarm devices, specifically an automatic monitoring and alarm device for a sulfur hexafluoride pressure gauge. Background Technology

[0002] Sulfur hexafluoride (SF6) is a man-made inert gas commonly used in electrical equipment. It is typically stored in sealed containers. Due to its high density, SF6 leaks easily deposit in low-lying areas, leading to a decrease in local oxygen concentration and potentially causing asphyxiation. Furthermore, even low concentrations of SF6 can cause dizziness and other neurological symptoms. Therefore, for enhanced safety, pressure monitoring of the container is essential to detect any SF6 leaks.

[0003] Currently, pressure monitoring of containers still relies on pressure gauges installed on the containers. Leakage is determined by reading changes in the gauge readings over a certain period. However, if workers approach the container to read the values, there are safety hazards if a leak has already occurred. Furthermore, workers cannot anticipate leaks in their initial stages, making this method ineffective. Therefore, the current approach involves using a network-enabled camera to periodically photograph the pressure gauge dial. These photos are then transmitted to a computer (or mobile phone), where built-in software performs image recognition and reads the dial readings. An initial reading is set in the software; if the photographed reading differs from the initial reading, a leak is detected, and the computer issues an alarm to promptly alert the workers.

[0004] Currently, the camera is mounted on the pressure gauge using a simple bracket, which is slow to install. After installation, the distance between the camera and the gauge needs to be adjusted multiple times to ensure clear photos and prevent false alarms caused by subsequent computer text recognition errors, further reducing the installation speed. Utility Model Content

[0005] The purpose of this invention is to provide an automatic monitoring and alarm device for sulfur hexafluoride pressure gauges. This invention has the advantages of quick and convenient installation and easy maintenance.

[0006] The technical solution of this utility model: an automatic monitoring and alarm device for a sulfur hexafluoride pressure gauge, including a camera installed on the front side of the pressure gauge dial, the camera having network connectivity, a mounting sleeve on the camera, a mounting sleeve connected to a mounting cylinder via a mounting arm, and the mounting cylinder connected to the gauge dial via a mounting structure.

[0007] The mounting structure includes a connecting plate fixed to the mounting cylinder. The connecting plate is connected to two movable seats through two hinge shafts. The movable seats are provided with arc-shaped fixing hoops. The two fixing hoops are located on both sides of the dial. An anti-slip pad is provided between the fixing hoops and the dial. An arc-shaped support piece is provided on one side of the fixing hoops. A locking mechanism is provided between the two movable seats.

[0008] In the aforementioned sulfur hexafluoride pressure gauge automatic monitoring and alarm device, the anti-slip pad is fixed to the fixing hoop.

[0009] In the aforementioned automatic monitoring and alarm device for sulfur hexafluoride pressure gauges, the hinge shaft is fixed to the connecting plate.

[0010] In the aforementioned automatic monitoring and alarm device for sulfur hexafluoride pressure gauges, one end of the mounting arm is inserted into the mounting sleeve. Both sides of the mounting arm are provided with grooves, and spring pieces are provided inside the grooves. One end of the spring piece is fixed to the bottom surface of the groove, and the other end of the spring piece is provided with a positioning block. The inner wall of the mounting sleeve is provided with a slot that cooperates with the positioning block.

[0011] In the aforementioned automatic monitoring and alarm device for sulfur hexafluoride pressure gauges, the other end of the mounting arm is inserted into the mounting sleeve and threaded rods are provided on both sides. Positioning grooves are provided on both sides of the mounting sleeve, and through grooves are provided on the bottom surface of the positioning grooves. The threaded rods pass through the through grooves and are provided with positioning nuts.

[0012] In the aforementioned sulfur hexafluoride pressure gauge automatic monitoring and alarm device, the positioning nut is a flange nut, and the diameter of the positioning nut matches the width of the positioning groove.

[0013] In the aforementioned sulfur hexafluoride pressure gauge automatic monitoring and alarm device, the center line of the positioning groove and the center line of the through groove are on the same plane.

[0014] In the aforementioned automatic monitoring and alarm device for sulfur hexafluoride pressure gauges, the mounting sleeve is L-shaped.

[0015] Compared with the prior art, this utility model is equipped with a fixing hoop, fixing bolt, movable seat, connecting plate, fixing nut, support plate, anti-slip pad, and hinge shaft. When installing the device, the two fixing hoops are opened and fitted onto the two sides of the outside of the pressure gauge dial. Then, the two sets of fixing hoops are tightened so that the anti-slip pad inside the fixing hoop is in contact with the outside of the pressure gauge dial. Next, the fixing bolt is passed through the inside of the movable seat. Finally, the fixing nut is fitted onto the outside of the fixing bolt and tightened so that the two fixing hoops hold the dial tightly, achieving alignment between the camera and the dial. At the same time, the support plate at one end of the fixing hoop is attached to one end of the pressure gauge dial to support the main body of the device, enabling quick installation.

[0016] The device is equipped with a mounting cylinder, mounting arm, positioning blocks, springs, grooves, and slots. When the monitoring device needs to be disassembled and repaired, the positioning blocks can be pressed from both sides to disengage them from the slots. Then, the mounting arm can be pulled out from inside the mounting cylinder to remove the camera for repair. After that, the mounting arm can be inserted into the mounting cylinder. The springs on both sides of the mounting arm will spring back and push the positioning blocks out to engage with the slots. The mounting cylinder and mounting arm will then reconnect, allowing the camera to be easily disassembled and repaired.

[0017] The device, equipped with an installation arm, positioning groove, installation sleeve, through groove, threaded rod, and positioning nut, allows the positioning nuts on both sides to be rotated to disengage from the positioning groove after installation. The installation sleeve can then be pulled to adjust the distance between the camera and the pressure gauge dial, ensuring clear image capture. Once the distance is appropriate, the positioning nut is rotated back to fit snugly inside the positioning groove. The threaded rod then positions the installation arm, allowing for adjustable installation distance, ensuring clear camera images, preventing text recognition errors, and avoiding false alarms.

[0018] In summary, this utility model has the advantages of quick and convenient installation and easy maintenance. Attached Figure Description
