[0002] Chemical workshops contain flammable and explosive gases or dust, placing extremely high demands on the explosion-proof performance of electrical equipment. Existing ordinary clocks and watches cannot meet these requirements, and traditional explosion-proof clocks and watches mostly use mechanical displays or low-brightness LCD screens, which have the following drawbacks: Insufficient safety: Some explosion-proof clocks and watches only rely on the outer casing for explosion protection and do not meet the intrinsically safe explosion-proof standard, posing a risk of ignition by electrical sparks; Poor readability: The display has low brightness and weak color penetration, making it difficult to see from 30 meters away in dusty or foggy environments; Time calibration is inconvenient: it relies on manual adjustment, which is prone to errors and has high maintenance costs; Power outage timing failure: There is no backup power supply design, and the timing cannot continue after a power outage, affecting the accuracy of production scheduling; The aforementioned defects together result in LED clocks failing to meet the actual needs of chemical workshops, leading to unsatisfactory performance.

[0022] An explosion-proof LED clock for use in a chemical workshop includes a first housing 1, a fixing device mounted on the outer surface of the first housing 1, a calibration device mounted inside the first housing 1, and a display device mounted on the first housing 1. The fixing device includes a fixing pin 2, a fixing bolt 3 mounted on the end of the fixing pin 2 away from the first housing 1, a wiring port 4 mounted on the top of the first housing 1, a first fixing plate 5 mounted on the first housing 1, a second fixing plate 6 mounted on the first fixing plate 5, a second housing 7 mounted in the middle of the second fixing plate 6, a hinge 8 mounted on one side of the first fixing plate 5 and the second fixing plate 6, a connecting bolt 9 mounted on the second fixing plate 6, a first sealing ring 10 mounted in the middle of the first fixing plate 5 and the second fixing plate 6, a sealing strip 11 mounted inside the first sealing ring 10, and a second sealing ring 12 mounted inside the sealing strip 11.

[0023] The fixed pins 2 are fixedly installed at both ends of the back of the first housing 1. The first fixed plate 5 and the second fixed plate 6 are fixedly connected by connecting bolts 9 and hinged by hinges 8. The first sealing ring 10 is installed inside the first sealing groove near the outer side of the first fixed plate 5 and the second fixed plate 6. The sealing strip 11 is fixedly installed inside the second sealing groove in the middle of the side of the first fixed plate 5 and the second fixed plate 6 near each other. The second sealing ring 12 is fixedly installed inside the third sealing groove in the middle of the side of the first fixed plate 5 and the second fixed plate 6 near each other. Through the combined action of the first sealing ring 10, the sealing strip 11, and the second sealing ring 12, the sealing performance at the housing connection is effectively increased, preventing dust and other particles from entering the clock and effectively improving explosion-proof safety.

[0024] During installation, the clock is fixed to the wall using the fixing pin 2 and fixing bolt 3. When assembling the first housing 1, the first fixing plate 5, the second fixing plate 6, and the second housing 7, the connection between the first fixing plate 5 and the second fixing plate 6 is sealed using the first sealing ring 10, the sealing strip 11, and the second sealing ring 12. The I-shaped cross-section design of the first sealing ring 10 and the second sealing ring 12 effectively improves the overall sealing effect. Thus, the three-layer sealing protection effectively prevents flammable and explosive gases and dust from entering the clock, effectively improving explosion-proof safety.

[0025] The calibration device includes a backup power supply 13, a wireless calibration module 14 installed on one side of the backup power supply 13, a remote control calibration module 15 installed at the bottom of the wireless calibration module 14, a radio wave calibration module 16 installed on one side of the remote control calibration module 15, and an antenna 17 installed above the middle of the radio wave calibration module 16. The backs of the backup power supply 13, the wireless calibration module 14, and the remote control calibration module 15 are fixedly connected to one side of the back of the inner wall of the first housing 1.

[0026] The display device includes a double-layer tempered glass 18, with a display screen 19 connected to the back of the double-layer tempered glass 18. A control chip 20 is installed on the back of the display screen 19. The display screen 19 is fixedly installed inside the mounting hole in the middle of the second housing 7. The double-layer tempered glass 18 is fixedly installed on the display screen 19. The control chip 20 is fixedly connected to the inner wall of the second housing 7. The double-layer tempered glass 18 can effectively increase the safety of the display screen 19 from collision damage. The anti-glare coating on the double-layer tempered glass 18 can effectively increase the light transmittance and improve visibility.

[0027] During operation, the backup power supply 13 is installed so that it remains in a float charging state during normal power supply. In the event of a power outage, the backup power supply 13 immediately switches to provide power. Simultaneously, a buzzer alarm sounds when the backup power supply 13 reaches low battery (≤20%). For daily use, the wireless calibration module 14, with its built-in Wi-Fi module, connects to the workshop's intranet NTP server for automatic time synchronization daily (error ≤±1s). The remote control calibration module 15, equipped with an infrared receiver (receiving distance ≥5 meters), supports manual calibration via a dedicated remote control. The radio wave calibration module 16 and antenna 17 receive time information from the China Radio Tower to synchronize with the national standard time. The installation of display screen 19 results in a rectangular LED display screen (resolution ≥320×160). The main display area displays hour and minute digits (font size ≥50mm), while the lower right corner displays the year, month, and day in smaller font (font size ≤10mm). The LED light source uses red light with a wavelength of 620-630nm (strong penetration) and a brightness ≥1000cd / m², ensuring visibility at 30 meters. Additionally, double-layered tempered glass 18 is installed on the outside of display screen 19 to protect it from impacts and reduce damage caused by collisions, thus ensuring normal use. Furthermore, the outer surface of the double-layered tempered glass 18 is coated with an AR / AG coating to eliminate strong light reflection from the chemical plant, effectively improving visibility.
