[0021] 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.

[0022] Please see Figure 1-6This utility model provides a technical solution: an anti-electromagnetic interference power equipment operation status monitoring device, including an operation status monitoring device body 1, a protective mechanism 2 provided on the outer surface of the operation status monitoring device body 1, and a heat dissipation component 3 provided on the inner surface of the operation status monitoring device body 1.

[0023] The protective mechanism 2 includes a filter 21, a protective shell 22, a protective door 23, a handle 24, an extension block 25, a buckle 26, a fixing block 27, a limiting post 28, a slide 29, a spring 210, a slider 211, a locking block 212, a connecting post 213, and a pressing plate 214. A filter 21 is provided on the outer surface of the main body 1 of the operation status monitoring device. A protective shell 22 is provided on the outer surface of the main body 1 of the operation status monitoring device. A protective door 23 is provided on one side surface of the protective shell 22. A handle 24 is fixedly connected to the outer surface of the protective door 23. An extension block 25 is fixedly connected to the outer surface of the protective door 23. A buckle 26 is fixedly connected to the outer surface of the extension block 25. A fixing plate 26 is fixedly connected to the outer surface of the protective shell 22. A fixing block 27 is connected, and a limiting post 28 is fixedly connected to the inner surface of the fixing block 27. A sliding groove 29 is opened on the inner surface of the limiting post 28, and a spring 210 is provided on the inner surface of the sliding groove 29. One end of the spring 210 is connected to a slider 211. A locking block 212 is fixedly connected to the inner surface of the fixing block 27. One end of the locking block 212 is connected to a connecting post 213, and one end of the connecting post 213 is connected to a pressing plate 214. Through the setting of filter 21, protective shell 22, protective door 23, handle 24, extension block 25, buckle 26, fixing block 27, limiting post 28, sliding groove 29, spring 210, slider 211, locking block 212, connecting post 213 and pressing plate 214, firstly... A filter 21 is installed at the power supply of the operation status monitoring device 11. The input terminal of the filter 21 is electrically connected to the external power supply, and the output terminal of the filter 21 is electrically connected to the operation status monitoring device 11. The filter 21 filters the electromagnetic waves generated by the external power supply, preventing interference to the electronic components inside the main body 1 of the operation status monitoring device and improving the device's operational stability. The protective shell 22 and the protective door 23 are made of shielding material, which can block external electromagnetic wave interference, further enhancing the device's anti-interference capability. The protective door 23 is engaged with the fixing block 27 via a buckle 26, ensuring a tight connection between the protective shell 22 and the protective door 23 and preventing electromagnetic wave leakage. When the protective door 23 needs to be opened, press the press plate 214. Since the connection between the locking block 212 and the connecting column 213 is made of deformable material, the press plate 214 drives the locking block 212 to move through the connecting column 213, causing the locking block 212 to disengage from the buckle 26. At this time, the compressed spring 210 returns to its original state and pushes the slider 211 to pop out the buckle 26, thus opening the protective door 23. When the protective door 23 needs to be closed, insert the buckle 26 into the inside of the fixing block 27 and engage the buckle 26 with the locking block 212 to close the protective door 23. The protective mechanism 2 not only enhances the device's anti-electromagnetic interference capability but also facilitates the opening and closing of the protective door 23, improving the ease of operation.

[0024] Furthermore, the heat dissipation assembly 3 includes a cooling fan 31, an air inlet 32, a first dust filter 33, a first screw 34, an air outlet 35, a mounting groove 36, a second dust filter 37, and a second screw 38. The cooling fan 31 is mounted on the inner surface of the protective shell 22. An air inlet 32 ​​is formed on the bottom wall of the protective shell 22. A first dust filter 33 is mounted on the inner surface of the air inlet 32. A first screw 34 is mounted on the outer surface of the first dust filter 33. An air outlet 35 is formed on the upper surface of the protective shell 22. A mounting groove 36 is formed on the upper surface of the protective shell 22. A second dust filter 37 is mounted on the inner surface of the mounting groove 36. A second screw 38 is mounted on the outer surface of the second dust filter 37. The cooling fan 31, air inlet 32, first dust filter 33, first screw 34, air outlet 35, mounting groove 36, and second dust filter 38 are connected. The installation of the mesh 37 and the second screw 38 allows the cooling fan 31 to start during use, drawing heat from inside the protective shell 22 through the air inlet 32 ​​and expelling it through the air outlet 35, creating airflow and effectively reducing the internal temperature of the device, ensuring the normal operation of electronic components. Simultaneously, the first dustproof mesh 33 and the second dustproof mesh 37 effectively prevent external dust from entering the device, avoiding contamination and damage to electronic components and extending the device's lifespan. The first screw 34 and the second screw 38 securely install the first dustproof mesh 33 and the second dustproof mesh 37 onto the air inlet 32 ​​and the mounting groove 36, ensuring the stability and reliability of the dustproof mesh. Furthermore, it facilitates the disassembly and installation of the first dustproof mesh 33 and the second dustproof mesh 37, as well as the cleaning and replacement of the first dustproof mesh 33.

[0025] Furthermore, the main body 1 of the operation status monitoring device includes an operation status monitoring device 11, a display 12 and an indicator light 13. The display 12 is provided on the outer surface of the operation status monitoring device 11, and the indicator light 13 is provided on the outer surface of the operation status monitoring device 11.

[0026] Furthermore, the buckle 26 and the locking block 212 form an engaging structure. The limiting post 28 is symmetrically arranged with respect to the width axis of the locking block 212. Through the setting of the buckle 26, the protective door 23 can be firmly locked onto the fixing block 27, preventing the protective door 23 from being accidentally opened when subjected to external force, thus improving the safety of the device. At the same time, the limiting post 28 is symmetrically arranged with respect to the width axis of the locking block 212, so that the locking block 212 can remain stable when moving, without shaking or shifting, further ensuring the engaging effect between the buckle 26 and the locking block 212.

[0027] Furthermore, the slide groove 29 and the slider 211 form a sliding structure. The inner surface of the slide groove 29 matches the outer surface of the slider 211. The slide groove 29 provides a stable sliding track for the slider 211, allowing the slider 211 to move smoothly inside the slide groove 29. When the pressing plate 214 is pressed, the connecting post 213 drives the locking block 212 to move. At this time, the slider 211 slides inside the slide groove 29. With the elastic action of the spring 210, the locking block 212 and the buckle 26 are quickly separated.

[0028] Furthermore, the outer surface of the first dustproof net 33 is provided with equal-spaced first screws 34. The first screws 34 penetrate the first dustproof net 33 and connect it to the protective shell 22. The first dustproof net 33 effectively blocks external dust from entering the protective shell 22 through the air inlet 32, ensuring the cleanliness of the device. At the same time, the equal-spaced distribution of the first screws 34 on the outer surface of the first dustproof net 33 ensures that the first dustproof net 33 can be firmly installed at the air inlet 32 ​​without loosening or falling off, further improving the stability and reliability of the device. In addition, the design of the first screws 34 also facilitates the disassembly and installation of the first dustproof net 33. When it is necessary to clean or replace the first dustproof net 33, simply unscrew the first screws 34 to easily remove the first dustproof net 33, making the operation simple and quick.

[0029] Furthermore, second screws 38 are evenly distributed on the outer surface of the second dustproof net 37. The second screws 38 penetrate the second dustproof net 37 and connect it to the protective shell 22. The second dustproof net 37 effectively blocks external dust from entering the interior of the protective shell 22 through the air outlet 35, further improving the cleanliness of the device and ensuring the normal operation of electronic components. At the same time, the evenly distributed second screws 38 on the outer surface of the second dustproof net 37 not only enhance the connection stability between the second dustproof net 37 and the protective shell 22, but also facilitate the disassembly and installation of the second dustproof net 37. When the second dustproof net 37 accumulates too much dust and needs to be cleaned or replaced, the staff can easily remove the second dustproof net 37 by simply unscrewing the second screws 38, greatly simplifying the maintenance process and improving work efficiency.

[0030] Working Principle: In actual operation, a filter 21 is first installed at the power supply of the operation status monitoring device 11. The input terminal of the filter 21 is electrically connected to the external power supply, and the output terminal of the filter 21 is electrically connected to the operation status monitoring device 11. Through the filter 21, electromagnetic waves generated by the external power supply can be filtered, preventing interference to the electronic components inside the main body 1 of the operation status monitoring device and improving the operational stability of the device. The protective shell 22 and the protective door 23 are made of shielding material, which can block interference from external electromagnetic waves, further enhancing the device's stability. The device's anti-interference capability is enhanced by the protective door 23 being engaged with the fixing block 27 via the buckle 26, ensuring a tight connection between the protective shell 22 and the protective door 23 and preventing electromagnetic wave leakage. When the protective door 23 needs to be opened, pressing the pressing plate 214 causes the buckle 212 to move via the connecting post 213, disengaging it from the buckle 26. At this point, the compressed spring 210 returns to its original position, pushing the slider 211 to pop out the buckle 26, thus opening the protective door 23. When closing the protective door 23, insert the buckle 26 into the inside of the fixing block 27 and engage the buckle 26 with the locking block 212 to close the protective door 23. The protective mechanism 2 not only enhances the device's anti-electromagnetic interference capability but also facilitates the opening and closing of the protective door 23, improving operational convenience. Furthermore, the improved heat dissipation component 3 ensures that the cooling fan 31 starts during use, drawing heat from inside the protective shell 22 through the air inlet 32 ​​and expelling it through the air outlet 35, creating air circulation and effectively reducing the internal temperature of the device, thus protecting the electronic components. The first dustproof net 33 and the second dustproof net 37 are designed to ensure the normal operation of the device. They effectively prevent external dust from entering the device, avoiding dust contamination and damage to electronic components and extending the service life of the device. The first screw 34 and the second screw 38 are used to firmly install the first dustproof net 33 and the second dustproof net 37 on the air inlet 32 ​​and the mounting groove 36, ensuring the stability and reliability of the dustproof net. In addition, it is easy to disassemble and install the first dustproof net 33 and the second dustproof net 37, as well as to clean and replace the first dustproof net 33.
