Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and in particular to an intelligent electrical cabinet ventilation vent filter device. Background Technology

[0002] In urban rail transit power supply systems, most electrical equipment is enclosed in metal cabinets, and due to its high power and heat dissipation, ventilation openings are required when using air cooling. However, the environment in which the equipment is located can sometimes be harsh, filled with dust, metal shavings, and other contaminants, which can enter the equipment through the ventilation openings, potentially causing short circuits and other malfunctions.

[0003] Existing protection methods involve installing simple filtration devices at the ventilation openings, using only a single-layer filter. This provides poor protection; when the filter mesh is small, dust accumulates over time, affecting heat dissipation; when the mesh is large, dust can still pass through and enter the cabinet, resulting in ineffective filtration. Therefore, it is crucial to ensure effective filtration while maintaining adequate heat dissipation. Existing filtration systems require improvement in terms of intelligence and protection.

[0004] Therefore, an intelligent electrical cabinet ventilation vent filter device is provided to address the shortcomings of existing technologies. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an intelligent electrical cabinet ventilation outlet filter device, which aims to solve the problem of not being able to meet the heat dissipation performance and filtration effect in real time.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] When in single-layer filtration state: the secondary filter layer is wound around the rotating shaft, and the primary filter layer performs single-layer filtration;

[0015] When in dual-layer filtration mode: the secondary filter layer covers the vent, and the primary filter layer and the secondary filter layer work together for filtration.

[0033] Reference Figures 1 to 5 A smart electrical cabinet 3 ventilation port filter device is installed at the ventilation port of the electrical cabinet 3, including a mounting plate 1, a filter mechanism 2, a controller and an air quality sensor;

[0034] In embodiment 1, the mounting plate 1 is fixedly connected to the electrical cabinet 3; the filtration mechanism 2 includes a driver 21, a rotating shaft 22, a primary filter layer 23, and a secondary filter layer 24. The driver 21 is fixedly connected to the mounting plate 1, and the output end of the driver 21 is connected to the rotating shaft 22. The primary filter layer 23 is fixedly connected to the mounting plate 1 to cover the ventilation opening of the electrical cabinet 3, and the secondary filter layer 24 is fixedly connected to the rotating shaft 22; the controller is fixedly connected to the mounting plate 1 and connected to the driver 21; the air quality sensor is connected to the controller and is used to monitor the air quality inside and / or outside the electrical cabinet 3 in real time.

[0035] The filter mechanism 2, controller, and air quality sensor are integrated and mounted on the ventilation opening of the electrical cabinet 3 via a mounting plate 1. The air quality sensor monitors the air quality inside the electrical cabinet 3 in real time. When the detected pollutant level is low, the primary filter layer 23 covers the ventilation opening of the electrical cabinet 3, and the secondary filter layer 24 is wound around the rotating shaft 22. When the detected pollutant level is high, the air quality sensor transmits a signal to the controller. Upon receiving the signal, the controller sends a command to activate the driver 21. The driver 21 opens the secondary filter layer 24 via the rotating shaft 22, covering the ventilation opening of the electrical cabinet 3. The filtration performance of the filter device can be adjusted in real time according to the air quality. This intelligent electrical cabinet 3 ventilation opening filter device features real-time performance in meeting both heat dissipation and filtration needs.

[0036] In one embodiment, the filtration device further includes an airflow sensor and an alarm. The airflow sensor is connected to the controller and is used to detect the airflow in real time. Since the filter mechanism 2 requires regular cleaning, and staff only schedule cleaning times based on experience, timely cleaning cannot be guaranteed, thus affecting the real-time airflow of the vents. Therefore, an alarm is connected to the airflow sensor. When insufficient airflow is detected for heat dissipation, the alarm is triggered, reminding staff to clean and maintain the filter in a timely manner to ensure heat dissipation performance.

[0037] In one embodiment, the filter mechanism 2 includes a single-layer filtration state and a double-layer filtration state: In the single-layer filtration state, the secondary filter layer 24 is in a non-working state and is wound around the rotating shaft 22, and the primary filter layer 23 performs single-layer filtration; In the double-layer filtration state, the driver 21 drives the rotating shaft 22 to open the secondary filter layer 24 to cover the vent, and the primary filter layer 23 and the secondary filter layer 24 perform filtration together.

[0038] In one embodiment, refer to Figures 4-5 As shown, the filter mechanism 2 also includes a first tension rope 25, and the mounting plate 1 is provided with a first protrusion 11. The secondary filter layer 24 includes a first filter body 241 and a slider 242. The slider 242 is fixedly connected to the upper end and / or lower end of the first filter body 241. One end of the first tension rope 25 is fixedly connected to the first protrusion 11, and the other end of the first tension rope 25 is fixedly connected to the slider 242. The mounting plate 1 also includes a first groove 12 that is slidably connected to the slider 242. When the secondary filter layer 24 needs to be opened, the first tension rope 25 is in a taut state. The driver 21 is activated, and the output shaft of the driver 21 drives the rotating shaft 22 to rotate clockwise. While the rotating shaft 22 is rotating, the first filter body 241 is released. The first tension rope 25 pulls out the first filter body 241, and at the same time, the slider 242 slides along the first slide groove 12 to the end away from the rotating shaft 22. When the secondary filter layer 24 needs to be closed, the first tension rope 25 is in a normal state. The driver 21 is activated, and the output shaft of the driver 21 drives the rotating shaft 22 to rotate counterclockwise. While the rotating shaft 22 is rotating, the first filter body 241 is retracted, the first tension rope 25 is taut, and at the same time, the slider 242 slides along the first slide groove 12 to the end of the rotating shaft 22.

[0039] In embodiment 2, the filter mechanism 2 further includes a second tension rope. A second protrusion is provided on the mounting plate 1. One end of the second tension rope is fixedly connected to the end of the secondary filter layer 24 away from the rotating shaft 22. The other end of the second tension rope passes around the second protrusion and is fixedly connected to the rotating shaft 22. When the secondary filter layer 24 needs to be opened, the driver 21 is activated. The output shaft of the driver 21 drives the rotating shaft 22 to rotate clockwise. Simultaneously, the second tension rope wraps around the rotating shaft 22, and the other end of the second tension rope pulls out the secondary filter layer 24 wrapped around the rotating shaft 22. When the secondary filter layer 24 needs to be closed, the driver 21 is activated. The output shaft of the driver 21 drives the rotating shaft 22 to rotate counterclockwise. Simultaneously, the rotating shaft 22 wraps around the secondary filter layer 24, and the end of the second tension rope wrapped around the rotating shaft 22 pulls out. The distance the second tension rope and the secondary filter layer 24 move are the same. Preferably, the outer surface of the second protrusion is provided with an annular groove, and the second tension rope slides within the annular groove.

[0040] In embodiment 3, the secondary filter layer 24 includes a second filter body and a guide strip. The guide strip is fixedly connected to the upper end and / or lower end of the second filter body. The mounting plate 1 also includes a second groove that is slidably connected to the guide strip.
