Detailed Implementation

[0027] 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.

[0028] Reference Figures 1-4 The present invention provides an embodiment of a warning current detection device, comprising a housing 1, wherein a detection component and a warning component for improving safety are connected inside the housing 1, a top cover 2 is hinged to the top of the housing 1, and a buckle component 3 for improving maintenance efficiency is connected between the housing 1 and the top cover 2.

[0029] The buckle assembly 3 includes a buckle block 4, the top of which is fixedly connected to the bottom of the top cover 2. A buckle groove 5 is provided on the inner side of the outer shell 1. The buckle block 4 slides inside the buckle groove 5. A limit groove 7 is provided inside the buckle block 4. A limit block 6 is slidably connected inside the limit groove 7. One end of the limit block 6 is fixedly connected to the inner side of the buckle groove 5, which facilitates quick disassembly of the top cover 2.

[0030] The detection components include a current sensing module 8, a controller 9, and a signal processing module 10. All three modules are located at the bottom of the housing 1. The warning components include a mounting bracket 11, an alarm light 12, and a buzzer 13. One end of the mounting bracket 11 is fixedly connected to the inside of the housing 1. The alarm light 12 and buzzer 13 are both connected to the inside of the mounting bracket 11 to promptly alert personnel. A display screen 17 is connected to the front of the housing 1 to display the detected current value in real time, allowing personnel to intuitively understand the current status. An adjustment button 19 is connected to the rear of the housing 1 for adjusting parameters such as the current threshold and alarm volume to meet the needs of different usage scenarios. A power interface 18 is located on one side of the housing 1 to connect to an external power source, supplying power to the electronic components inside the housing 1 to ensure normal operation of the device. The housing 1 also has... A detection hole 16 is provided inside one side, allowing external circuit wires to pass through, so that the current sensing module 8 can come into contact with the current and realize the current signal detection. The current sensing module 8, controller 9, signal processing module 10, warning light 12, buzzer 13, display screen 17, power interface 18 and adjustment button 19 are all electrically connected. A light-transmitting hole 14 and a sound-transmitting hole 15 are provided inside the front end of the outer casing 1. The light-transmitting hole 14 allows the light of the warning light 12 to pass through the outer casing 1, making it easy for the outside to observe the warning light signal. The sound-transmitting hole 15 allows the sound of the buzzer 13 to be transmitted out of the outer casing 1, ensuring that the warning sound can be heard by the staff. A lever 20 is fixedly connected to the front end of the top cover 2, which is convenient for the staff to apply force. By pulling the lever 20, the locking state of the buckle assembly 3 can be released. The buckle assembly 3 is made of elastic plastic material, which is easy to operate and saves maintenance time.

[0031] Working principle: During operation, the external circuit wires pass through the detection hole 16. The current sensing module 8 senses the current signal in the wires in real time and converts it into an electrical signal, which is then transmitted to the controller 9. The controller 9 analyzes and processes the received signal and compares it with a preset current threshold. If the current value is within the normal range, the display screen 17 continuously displays the current value in real time. Once the detected current value exceeds the threshold, the controller 9 immediately sends a trigger signal to the warning light 12 and the buzzer 13 in the warning component. The warning light 12 flashes through the light-transmitting hole 14, and the buzzer 13 emits an alarm sound through the sound transmission hole 15. At the same time, the display screen 17 displays the abnormal current value, promptly alerting the staff. When maintenance and repair of the device are required, the staff lifts the lever 20 at the front end of the top cover 2. The elastic plastic buckle component 3 deforms under force, and the limiting block 6 in the locking block 4 slides in the limiting groove 7, causing the locking block 4 to disengage from the locking groove 5. The top cover 2 is then quickly removed. After the maintenance is completed, the top cover 2 is reset. Pressing the top cover 2 automatically locks the buckle component 3, ensuring the normal operation of the device.
