[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] This utility model relates to a preferred embodiment of a quick-release structure for an electrical cabinet filtration system.

[0022] Please see Figures 1 to 6 The quick-release structure of the electrical cabinet filtration system includes an electrical cabinet body 1, a mounting frame 2, a flip-up filter assembly, and a quick-locking assembly. The electrical cabinet body 1 has a ventilation opening 3 on its side wall, the mounting frame 4 is fixedly located around the ventilation opening 3, and the mounting frame 2 has a flip-up filter assembly 5 and a quick-locking assembly 6 for quickly locking the filter assembly 5.

[0023] The connections between the various components are robust, and the whole system possesses high stability and reliability, making it suitable for the long-term, high-intensity use requirements of high-speed rail electrical cabinet filtration systems.

[0024] Specifically, the first is the flip-up filter assembly 5, which includes a filter screen 51, filter cotton, and an outer sealing plate 52 that encapsulates the filter screen 51 and filter cotton. The first side 53 of the outer sealing plate 52 is rotatably connected to the mounting frame 4, so that the filter assembly 5 can be flipped up, making it convenient to maintain or replace the filter screen and filter cotton.

[0025] In this embodiment, the mounting frame 2 is an integrated metal frame structure with a rectangular frame structure, which ensures structural strength and improves manufacturing efficiency through mass production.

[0026] Furthermore, the filter screen 51 is a stainless steel woven filter screen with a mesh count of 60-80 mesh. It is made of stainless steel and not only has good filtration performance, effectively blocking external dust and impurities from entering the electrical cabinet, but also has excellent durability, can adapt to complex environments, and extend its service life.

[0027] The filter cotton is located inside the filter screen. The filter cotton is made of polyester fiber and has a thickness of 10-15mm. Its good adsorption performance can further adsorb fine dust and impurities that are not blocked by the filter screen, and work with the filter screen to improve the filtration effect.

[0028] The outer sealing plate 52 fixes the filter screen and filter cotton in place, which not only serves to fix them but also enhances the overall structural strength of the filter assembly.

[0029] Furthermore, the first side 53 of the outer sealing plate 52 is rotatably connected to the mounting frame 2 via a hinge shaft 4. The hinge shaft 4 is a detachable rotating shaft, and the axis of the hinge shaft 7 is parallel to the frame of the mounting frame 2.

[0030] Secondly, there is a quick-locking component 6, which is located on the second side 54 opposite to the first side 53. It includes at least two sets of fixing seats 61 on the mounting frame 2 and quick-locking screws 62 corresponding to the fixing seats 61. The quick-locking screws 62 rotatably pass through the outer cover plate 52 and extend into the lock hole of the mounting frame 2.

[0031] Setting at least two sets of fixing seats 61 and quick-lock screws 62 can ensure the stability of the filter assembly 5 in the locked state and prevent loosening due to the failure of a single locking point.

[0032] The quick-lock screw 62, when rotated, engages with or disengages from the lock hole 63, enabling rapid assembly and disassembly of the filter assembly 3. To lock, rotate the quick-lock screw 62 to insert its end into the lock hole 63; to disassemble, rotate it in the opposite direction to disengage its end from the lock hole 63. The operation is simple and quick, requiring no complex tools and significantly improving assembly and disassembly efficiency.

[0033] When it is necessary to remove the filter assembly 5 from the mounting frame 2 as a whole, the hinge shaft 4 can be further removed to facilitate thorough cleaning or replacement of the filter assembly 3. The axis of the hinge shaft 4 is parallel to the edge of the mounting frame 2, and the axis of the quick-lock screw 62 is perpendicular to the axis of the hinge shaft 4. This setting allows the quick-lock screw 62 to exert a force on the filter assembly 3 perpendicular to the plane of hinge shaft rotation during locking and releasing, ensuring reliable locking.

[0034] Locking and unlocking can be achieved by rotating the quick-lock screw 62. The operation is simple and requires no tools. At the same time, the hinge structure allows the filter assembly to be flipped open for easy cleaning or replacement of the filter media.

[0035] To ensure the airtightness of the filter assembly, a sealing strip is provided on the mating surface between the mounting frame 2 and the electrical cabinet body 1, and a sealing strip is also provided on the mating surface between the outer sealing plate 52 and the mounting frame 2.

[0036] The sealing strip is an elastic rubber sealing strip with a compression amount of not less than 2mm. It has good elasticity and aging resistance. After the filter assembly is installed, the compression deformation can tightly fill the gaps of the joint surface, which can effectively prevent dust, impurities and other contaminants from entering the electrical cabinet from the gaps.

[0037] This utility model also relates to an electrical cabinet, including the quick-release structure of the electrical cabinet filtration system. The filtration components of the electrical cabinet adopt a composite fixing method of hinge and quick lock, which makes the maintenance of the filtration system more convenient.

[0038] The installation and locking process of the filter component 5 is as follows: The first side 53 of the filter assembly 5 is rotatably connected via the hinge shaft 4. Then, the filter assembly 5 is rotated around the hinge shaft 4 so that its outer sealing plate 52 fits against the mounting frame 2. When locking, the operator rotates the quick-lock screw 62, causing the end of the quick-lock screw 62 to move axially until it is inserted into the corresponding lock hole 63 of the mounting frame, thereby locking the filter assembly 5. To unlock, the operator rotates the quick-lock screw 62 again, causing its end to exit from the lock hole 63, thus releasing the lock on the filter assembly 5 and allowing it to be easily removed.

[0039] The advantages of the quick-release structure of the electrical cabinet filtration system and the electrical cabinet itself are as follows: Easy and efficient operation: With the cooperation of two mounting brackets and two quick-lock screws, the filter components can be quickly installed and removed without the need for tools, which greatly shortens the maintenance time and improves the maintenance efficiency.

[0040] Reduced maintenance costs: It reduces damage to equipment caused by frequent disassembly, lowers maintenance costs and the risk of equipment failure, and extends the service life of the equipment.

[0041] Good sealing performance: The sealing rubber strip effectively ensures the sealing performance of the filtration system, improves the filtration effect, and better protects the electrical components inside the electrical cabinet.

[0042] Simple and reliable structure: The overall structure is reasonably designed with few parts, low manufacturing cost, and high stability and reliability, making it suitable for long-term use in high-speed rail electrical cabinet filtration systems.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
