DETAILED DESCRIPTION

[0023] See also Figure 1-5 , an air switch fault alarm device based on the Internet of Things, comprising an air switch 1, a detection mechanism 2 and an operating mechanism 3 are installed on the surface of the air switch 1;

[0024] The detection mechanism 2 enables the air switch 1 to have multiple detection functions and alarm functions, and the operating mechanism 3 enables the air switch 1 to be remotely operated.

[0025] The detection mechanism 2 includes a current detection module 201, an alarm module 202, a temperature detection module 203, a warning module 204, a microprocessing module 205 and a communication module 206. The microprocessing module 205 and the communication module 206 are both installed inside the air switch 1. The output ends of the current detection module 201, the communication module 206, the air switch 1 and the temperature detection module 203 are all electrically connected to the input end of the microprocessing module 205. The output end of the microprocessing module 205 is electrically connected to the input end of the communication module 206, the alarm module 202, the motor 303 and the warning module 204;

[0026] The current detection module 201 can detect the current of the wire connected to the air switch 1, the microprocessor module 205 can compare and analyze the current data, and transmit it to the Internet of Things cloud platform in real time through the communication module 206. The air switch 1 can also transmit its own status to the microprocessor module 205. When the current detection module 201 detects an abnormal current, or the temperature detection module 203 detects an abnormal temperature, the microprocessor module 205 can start the alarm module 202 and the warning module 204, and transmit a signal to the communication module 206, so that the alarm module 202 can issue a sound alarm, and the warning module 204 can emit a warning light to remind the surrounding people that the air switch 1 is in an abnormal state, and the communication module 206 can directly issue a prompt to the user through the Internet of Things cloud platform.

[0027] The operating mechanism 3 includes a mounting shell 301, a combined shell 302 is fixed on the surface of the mounting shell 301, a motor 303 is fixed on the surface of the combined shell 302, a connecting rod 304 is rotatably connected to the surface of the mounting shell 301, the output shaft of the motor 303 passes through the combined shell 302 and is fixedly connected to the connecting rod 304, a connecting plate 305 is fixed on the surface of the connecting rod 304, an operating rod 306 is fixed on the surface of the connecting plate 305, and the operating rod 306 is slidably connected to the switch on the surface of the air switch 1;

[0028] When the motor 303 is started, it will drive the connecting plate 305 to rotate through the connecting rod 304, so that the operating rod 306 drives the switch on the surface of the air switch 1 to rotate upward or downward, thereby realizing the automatic opening or closing of the switch. At the same time, the user can directly transmit a signal through the communication module 206 to operate the microprocessing module 205, and use the microprocessing module 205 to start the motor 303 to achieve the effect of remote control of the air switch 1, thereby avoiding the operator's hand contact with the air switch 1, avoiding the risk of electric shock caused by direct operation of the high-voltage switch, improving the safety of operation, and realizing automatic control of the air switch 1. The cooperation between the mounting shell 301 and the combined shell 302 can protect the switch on the surface of the air switch 1, avoid the switch from being directly exposed to the air, and prevent dust and dirt from entering the switch and affecting its normal operation.

[0029] Furthermore, the current detection module 201 is a current sensor, and the current sensor is fixed at the bottom of the air switch 1;

[0030] This ensures that the current detection module 201 can perform real-time detection of the current of the wire connected to the surface of the air switch 1 , and also enables the wire to pass through the current sensor normally and be connected to the bottom of the air switch 1 .

[0031] Furthermore, the alarm module 202 and the warning module 204 are a buzzer and a warning light respectively, and both the buzzer and the warning light are fixed on the surface of the air switch 1;

[0032] The buzzer can emit an alarm sound, and the warning light can emit light normally, thereby ensuring the normal operation of the alarm module 202 and the warning module 204, so that the air switch 1 can have an alarm effect when a fault occurs.

[0033] Furthermore, the temperature detection module 203 is a temperature and humidity sensor, and the temperature and humidity sensor is fixed on the top of the air switch 1;

[0034] The temperature and humidity sensor can monitor the surface temperature of the air switch 1 and the surrounding environment temperature in real time, ensuring that the air switch 1 can detect the temperature and humidity normally, so that the operator can better understand the environment in which the air switch 1 is located.

[0035] Furthermore, the mounting shell 301, the assembly shell 302, the connecting rod 304, the connecting plate 305 and the operating rod 306 are all made of ceramics;

[0036] Ceramic material has good insulation and flame retardant effects. It can effectively prevent operators from electric shock when they touch them and reduce the risk of burns.

[0037] Furthermore, an observation plate 307 is embedded and fixed on the surface of the combined shell 302, and the observation plate 307 is made of transparent material;

[0038] The setting of the observation plate 307 enables the operator to directly observe the switching status of the surface of the air switch 1 through it.

[0039] Furthermore, the width of the combined shell 302 is greater than the width of the connecting plate 305;

[0040] This ensures that the connecting plate 305 has enough space to rotate.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
