Description

Technical Field

[0001] This utility model relates to the field of new energy charging technology, specifically to a dust removal device for a DC charging pile filter. Background Technology

[0002] A DC charging station is a charging device that quickly replenishes the power of electric vehicles. It directly outputs DC power, bypassing the "slow" charging module inside the vehicle, thereby significantly shortening the charging time.

[0003] Currently, to ensure heat dissipation, ventilation openings are typically installed on the cabinet of the DC charging pile, and filters are installed in these openings. However, cleaning these filters is quite troublesome. The filter at the air inlet is the first line of defense. All dust, hair, fibers, and other particles in the air drawn in by the cooling fan must first pass through the filter at the air inlet. Most of these particles are blocked and accumulate on the filter at the air inlet. Before the airflow reaches the air outlet, it has already passed through the inside of the casing. At this point, most of the dust in the air has been captured by the filter at the air inlet. Therefore, the air flowing out of the casing is relatively clean, and the airflow passing through the air outlet filter contains very few particles, so naturally, there is not much dust to accumulate. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a dust removal device for DC pile filter screen, which can quickly remove dust by replacing the filter screens on both sides, thereby solving the problem mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a dust removal device for a DC pile filter screen, comprising a DC pile cabinet, ventilation openings on both sides of the DC pile cabinet, and a frame on each side of the DC pile cabinet directly opposite the ventilation openings. A positioning frame is installed inside the frame, one end of the positioning frame is inserted into the channel opening, and a filter screen is installed in the opening on the outside of the positioning frame. A connecting seat is installed on the outer surface of the frame, and a through hole is provided on the connecting seat. A connecting rod is provided in the through hole, and the other end of the connecting rod is bent and extended to the center of the top of the DC pile cabinet and connected to the shaft.

[0006] As a preferred technical solution, the connecting rods are all horizontally positioned at the end near the connecting seat, and each connecting rod has threads on its outer wall. Each connecting rod near the connecting seat is threaded with a locking ring, and one end face of the locking ring is in contact with the end face of the connecting seat. The connecting seat and the frame are both pressed against the outer surface of the DC pile cabinet by the locking ring.

[0007] As a preferred technical solution, a sealed bearing is embedded in the top surface of the DC pile cabinet, directly opposite the shaft, with one end of the shaft installed in the inner ring of the sealed bearing.

[0008] As a preferred technical solution, a mounting bracket is installed on one side of the interior of the DC pile cabinet. The mounting bracket is positioned opposite the ventilation opening, and the mounting bracket has multiple mounting holes, each of which is equipped with a cooling fan.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 This utility model discloses a dust removal device for a DC pile filter screen, comprising a DC pile cabinet 1, with ventilation openings 2 on both sides of the DC pile cabinet 1, and a frame 5 on each side of the DC pile cabinet 1 directly opposite the ventilation openings 2. A positioning frame 11 is installed inside the frame 5, with one end of the positioning frame 11 inserted into the channel opening. A filter screen 6 is installed in the opening on the outside of the positioning frame 11. A connecting seat 7 is installed on the outer surface of the frame 5, and a through hole is provided on the connecting seat 7. A connecting rod 9 is provided in the through hole, and the other end of the connecting rod 9 is bent and extended to the center of the top of the DC pile cabinet 1 and connected to a shaft 10.

[0021] In this embodiment, the connecting rod 9 is horizontally arranged at one end near the connecting seat 7, and the outer wall of the connecting rod 9 is provided with threads. The connecting rod 9 near the connecting seat 7 is threaded with a locking ring 8. One end face of the locking ring 8 is in contact with the end face of the connecting seat 7. The connecting seat 7 and the frame 5 are pressed together on the outer side of the DC pile cabinet 1 by the locking ring 8.

[0022] In this embodiment, a sealed bearing is embedded in the top surface of the DC pile cabinet 1, directly opposite the shaft 10, and one end of the shaft 10 is installed in the inner ring of the sealed bearing.

[0023] In this embodiment, a mounting bracket 3 is installed on one side of the interior of the DC pile cabinet 1. The mounting bracket 3 is positioned opposite to the ventilation opening 2. The mounting bracket 3 has multiple mounting holes, and each mounting hole is equipped with a cooling fan 4. The cooling fan is connected to the power supply inside the DC pile cabinet.

[0024] In this embodiment, a gap is formed between the end of the connecting seat 7 away from the cabinet and the bend of the connecting rod 9 to allow the connecting seat 7 to move outward, so that the connecting seat can move outward along the connecting rod until the positioning frame is moved out of the vent.

[0025] In this embodiment, the length and width of the positioning frame 11 match the length and width of the vent 2, which increases the stability after the positioning frame is inserted.

[0026] In this embodiment, a rubber layer is installed on the inner side of the frame 5, and the other side of the rubber layer is set to abut against the outer side of the DC pile cabinet 1. The rubber layer increases the sealing between the frame and the DC pile cabinet.

[0027] In this embodiment, the inner diameter of the through hole is matched with the diameter of the connecting rod 9, which increases stability and avoids swaying.

[0028] Working principle: The vent on the side closer to the fixed frame is the air outlet, while the vent on the side farther away from the fixed frame is the air inlet; As attached Figure 4 As shown, after the filter screen in the air inlet is covered with dust, the locking ring can be rotated to move outward along the threads. After the locking ring is no longer obstructed, the connecting seat and the frame can move outward along the connecting rod. The movement of the frame drives the positioning frame until the positioning frame is moved out of the vent. At this time, the connecting rod can be rotated around the shaft. The rotation of the connecting rod drives the frame and the filter screen, so that the frames on both sides can be replaced. The filter screen that was previously located inside the air outlet can be moved to the current air inlet, so that the filtration operation can be performed directly without affecting the airflow. After replacement, the frame can be pushed inward so that the inner side of the frame abuts against the outer wall of the DC pile cabinet, and the positioning frame can be inserted into the ventilation opening, while the locking ring can rotate in the opposite direction until it abuts against the end face of the connecting seat, thereby pressing and positioning the frame. After the filter screen, previously located in the air inlet, is moved to the air outlet, the airflow blows from the inside out. This force directly counteracts and overcomes the adsorption force that holds the dust in place. It applies a thrust to the dust that is completely opposite to the previous one, which is equivalent to pulling out a nail that has been "driven" in. This blows the dust off the filter screen. When the airflow suddenly sprays from the inside, the fibers on the filter screen will vibrate and shake at a high frequency to ensure the dust removal effect.

[0029] The connecting seat can be directly removed from the connecting rod after the frame rotates around the shaft, allowing for direct replacement of the frame and filter screen, which facilitates operation.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
