Its main function is to monitor the operating status of power equipment in real time, promptly detect abnormalities such as overload, short circuit, and equipment failure, and automatically disconnect faulty circuits to prevent the fault from spreading or causing a wider outage. Relay protection equipment consists of relays, sensors, and protective devices, and can respond rapidly when a power system fault occurs, ensuring the safety, reliability, and stability of power plant equipment. It is a crucial component for ensuring the operation of the power system.

[0003] Traditional dust prevention measures for power plant relay protection equipment often rely mainly on simple sealing structures to prevent dust from entering by reducing the contact between the relay box and the outside environment. In terms of dust removal, manual cleaning is usually used regularly to prevent dust from interfering with the relay protection equipment.

[0004] However, traditional dust removal methods for power plant relay protection equipment are inefficient in preventing dust from entering the relay box. Simple sealing structures cannot completely prevent dust from entering. Over time, dust will gradually accumulate inside the relay box, affecting the heat dissipation and normal operation of the equipment. Manual cleaning is not only labor-intensive and time-consuming, but also prone to damage to the equipment due to improper operation. Therefore, a dust removal device for power plant relay protection equipment is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a dustproof and dust-collecting device for power plant relay protection equipment, comprising a relay box 1, which houses the electrical components of the relay protection device. A hinge 2 is fixedly connected to one side of the relay box 1, which allows the box door 3 to be easily opened and closed. The box door 3 is fixedly connected to one side of the hinge 2 and has a sealing function, which can effectively prevent dust from entering the relay box 1 when closed. The box door 3 and the relay box 1 are connected by the hinge 2. A dust cover 4 is fixedly connected to one side of the relay box 1, and a dust-collecting component is provided inside the dust cover 4. A dust-proof component is also provided inside the dust cover 4.

[0035] The dust collection assembly includes an exhaust pipe 5 and a fan 7. The outer wall of the exhaust pipe 5 is fixedly connected to the inside of the dust cover 4. The exhaust pipe 5 is connected to the relay box 1. One end of the exhaust pipe 5 is connected to the relay box 1, and the other end discharges air through the fan 7. The fan 7 is installed inside the exhaust pipe 5 to drive the airflow. A valve 6 is fixedly connected to the outer wall of the exhaust pipe 5. The valve 6 is used to regulate the airflow channel. The dustproof assembly includes an inlet pipe 8 and a mounting ring 9. The outer wall of the inlet pipe 8 is fixedly connected to the inside of the dust cover 4 to guide air into the inside of the dust cover 4. The mounting ring 9 is fixedly connected to the outer wall of the inlet pipe 8.

[0036] Specifically, during the use of this relay protection device, when the dust inside the relay box 1 accumulates to a certain level, valve 6 can be opened to open the channel between the air outlet duct 5 and the relay box 1. At this time, the fan 7 starts working, using its strong suction to draw the dust inside the relay box 1 and small particles in the air into the air outlet duct 5, and then discharge the dust to the outside or a designated discharge area through this duct, ensuring the cleanliness and unobstructed flow inside the relay box 1. To prevent dust from being drawn in and re-entering the relay box 1 through the air outlet of the fan 7 during operation, valve 6 will be closed after the cleaning process is completed to avoid unnecessary secondary pollution. At the same time, inside the dust cover 4, air is introduced into the relay box 1 through the combined action of the filter screen 10 and the air inlet duct 8. The filter screen 10 can effectively block dust, particles and other impurities in the air, ensuring that only clean air enters the relay box 1, thereby preventing dust from re-entering the relay box 1, keeping the equipment clean and operating stably, and thus improving the safety and service life of the equipment.

[0037] Reference Figures 3-5 A filter screen 10 is installed at one end of the mounting ring 9. The filter screen 10 is used to intercept large dust particles in the air. The filter screen 10 has through holes 11 inside. A fixing base 20 is fixedly connected to one side of the mounting ring 9. A rotating column 12 is rotatably connected inside the fixing base 20. One end of the rotating column 12 is connected to the user via a knob 13 for easy manual adjustment. One end of the rotating column 12 is rotatably connected inside the mounting ring 9. A knob 13 is fixedly connected to the other end of the rotating column 12. By operating the knob 13, the user can easily clean or replace the filter screen 10. A turntable 14 is fixedly connected to the outer wall of the rotating column 12. An arc-shaped groove 15 is opened inside the turntable 14. A sliding groove 17 is opened inside the fixed base 20. A sliding column 16 is slidably connected inside the sliding groove 17. The shape of the sliding column 16 matches the arc-shaped groove 15 and can slide freely inside the arc-shaped groove 15, thereby adjusting the tightness or position of the filter screen 10. The sliding column 16 is slidably connected inside the arc-shaped groove 15. A connecting column 18 is fixedly connected to one end of the sliding groove 17. A locking block 19 is fixedly connected to one end of the connecting column 18. The locking block 19 is slidably connected to one side of the filter screen 10.

[0038] Specifically, when the filter screen 10 needs to be disassembled and maintained, first align the filter screen 10 with and attach it to one side of the mounting ring 9, ensuring that the mounting hole of the filter screen 10 is aligned with the positioning hole of the clip 19. Then, pass the through hole 11 inside the filter screen 10 through the outside of the clip 19 to fix the initial position of the filter screen 10. At this time, rotating the knob 13 causes the rotating column 12 to start rotating. The rotation of the rotating column 12 is transmitted to the turntable 14 on the outer wall, causing the turntable 14 to start rotating. The turntable 14 has an arc-shaped groove 15 inside, which can drive the sliding column 16 to move during the rotation of the turntable 14, so that the sliding column 16 slides linearly along the preset sliding groove 17. As the sliding column 16 moves, the connecting column 18 connected to its other end will also slide inside the fixed seat 20. When the connecting column 18 moves to a certain position, it drives the locking block 19 to expand outward on one side of the filter screen 10, so that the locking block 19 can be firmly locked on one side of the filter screen 10, ensuring that the filter screen 10 is fixed on the side of the mounting ring 9, improving the efficiency of filter screen 10 installation and removal, and making it convenient for maintenance personnel to clean or replace the filter screen 10 regularly.

[0039] Working Principle: When there is a lot of dust inside the relay box 1 during the use of this relay protection device, valve 6 can be opened to open the channel between the air outlet duct 5 and the relay box 1. At this time, the fan 7 will draw out the dust from inside the relay box 1 and discharge it through the air outlet duct 5. Finally, valve 6 will be closed to prevent dust from entering the relay box 1 through the air outlet of the fan 7. At the same time, during the dust extraction process inside the dust cover 4, external air enters the relay box 1 through the filter screen 10 and the air inlet duct 8. The filter screen 10 blocks the dust in the air, thus achieving an effective dust extraction and prevention effect inside the relay box 1. When it is necessary to disassemble and maintain the filter screen 10... First, the filter screen 10 is attached to the side of the mounting ring 9, and the through hole 11 inside the filter screen 10 is passed through the outside of the locking block 19. Then, the knob 13 is turned to drive the rotating column 12 to rotate. The rotating column 12 is forced to drive the turntable 14 on the outer wall to rotate. The turntable 14 drives the sliding column 16 to move through the internal arc groove 15, so that the sliding column 16 slides inside the sliding groove 17. At the same time, the sliding column 16 drives the connecting column 18 connected at one end to slide inside the fixing seat 20, so that the connecting column 18 drives the locking block 19 to expand outward on one side of the filter screen 10, thereby fixing the filter screen 10. This achieves the effect of quick disassembly and assembly of the filter screen 10 for easy maintenance.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
