Description

Technical Field

[0001] This invention relates to the technical field of communication engineering cabinets, and in particular to a communication engineering cabinet. Background Technology

[0002] Communication engineering is a core major in the field of electronic information engineering. It is a key engineering discipline supporting the construction of the digital economy, a strong network nation, and an intelligent society. Communication engineering cabinets are core basic support devices used in communication equipment rooms, data centers, base station equipment rooms, network cabinet rooms, and other scenarios for the integration, installation, fixing, protection, heat dissipation, and standardized management of communication equipment. They are important physical carriers that can ensure the stable operation of communication equipment, reliable signal transmission, and continuous online network connectivity.

[0003] Existing cabinet ventilation filters are installed by aligning the entire ventilation filter with the cabinet's ventilation opening area, precisely aligning the bolt holes on the filter with the pre-drilled holes on the cabinet panel, and then tightening the bolts diagonally to evenly distribute the force on the fixing frame. However, after tightening the bolts, the disassembly and assembly steps are numerous and time-consuming. In scenarios such as communication equipment rooms and base station cabinets where rapid maintenance and filter replacement are required, this seriously affects the efficiency of operation and maintenance and cannot meet the engineering requirements of efficient inspection and rapid repair. Related technologies include a cabinet body with an internal installation chamber. One side of the installation chamber is hinged to a cabinet door with an observation window inside. The top of the cabinet body has an air inlet with a dustproof mechanism, including a locking block. There are a pair of air outlets on both sides of the cabinet body, and the installation chamber has a first dustproof screen installed on both sides near the air outlets. Both pairs of air outlets have an adjustment mechanism, including two pairs of adjustment plates. The structure is simple and reasonable, the design is novel, and the operation is simple and convenient. It effectively prevents dust from entering the cabinet when dissipating heat, and avoids dust adhering to the machine parts, which affects the use of the parts. It has high practical value. However, when disassembling the dust screen, the operator needs to push the moving rods on both sides at the same time to drive the push rod to remove the locking block from the through hole. In actual operation, both hands need to apply force in sync. It is difficult for a single person to operate and requires a high degree of coordination. It is impossible to achieve quick disassembly with one hand, which affects the maintenance efficiency of the equipment. Summary of the Invention

[0017] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] Given that current technology makes it difficult for a single person to disassemble the dustproof net, requires a high degree of coordination, and cannot achieve quick disassembly with one hand, it affects the maintenance efficiency of the equipment.

[0020] like Figure 1-6 As shown, this embodiment of the invention provides a communication engineering cabinet, including a cabinet body 10: a self-cleaning mechanism 2 is provided on the top of the cabinet body 10, the self-cleaning mechanism 2 is used to self-clean the filter screen, and an unlocking mechanism 3 is provided on the top left side of the cabinet body 10, the unlocking mechanism 3 is used to remove and fix the filter screen. The self-cleaning mechanism 2 includes a first mounting frame 20, which is fixedly connected to the top of the cabinet 10. A first filter 21 is slidably connected to the inner wall of the first mounting frame 20. A recessed block 26 is fixedly connected to the front side of the first mounting frame 20. A vertical plate 23 is fixedly connected to the top of the cabinet 10. A servo motor 24 is fixedly connected to the rear side of the vertical plate 23. A gear 25 is fixedly connected to the output end of the servo motor 24. Hollow blocks 27 are fixedly connected to both the left and right sides of the top of the cabinet 10. Hollow blocks 27 are fixedly connected to both the left and right sides. Brushes 28 are rotatably connected to the inner wall of hollow blocks 27. A second filter screen 22 is slidably connected to the inner wall of the left hollow block 27. Conductive wires 211 are provided on the top of both first mounting frames 20. Vacuum cleaners 210 are fixedly connected to the left and right sides of the top rear end of the cabinet 10. The suction end of the vacuum cleaner 210 is connected to the hollow block 27. Multiple toothed grooves 29 are opened on the outer side of the first filter screen 21 and the second filter screen 22. Gears 25 are meshed with the toothed grooves 29.

[0021] Working principle: In use, the first filter screen 21 and the second filter screen 22 are first snapped together and assembled. Then, they are pushed from the hollow block 27 into the first mounting frame 20 at the top of the cabinet 10 to complete the installation. When the first filter screen 21 needs cleaning, since both the first filter screen 21 and the second filter screen 22 have toothed grooves 29 on their outer sides, and the toothed grooves 29 are meshed with gears 25, turning on the servo motor 24 can drive the output gear 25 to rotate. Through the meshing action, the first filter screen 21 is driven to move into the hollow block 27 on the right. When the first filter screen 21 needs cleaning, the first filter screen 21 moves into the hollow block 27 on the right side. When the first filter 21 enters the hollow block 27 on the right, it will come into contact with the brush 28 inside the hollow block 27, thereby sweeping away the dust and impurities on the first filter 21. The conductive wire 211 is used to conduct and eliminate the static electricity accumulated on the surface of the filter in time during the operation of the filter, so as to avoid the electrostatic discharge interfering with the internal communication equipment. The swept dust will be sucked out and collected by the vacuum cleaner 210. After the first filter 21 has completely entered the hollow block 27 on the right, the second filter 22 will cover the top of the first mounting frame 20 to complete the automatic replacement and cleaning.

[0022] Furthermore, the unlocking mechanism 3 includes a horizontal plate 30, which is fixedly connected to the top left side of the cabinet 10. Multiple piston cylinders 31 are fixedly connected at equal intervals on the right side of the horizontal plate 30. A piston column 33 is slidably connected to the inner wall of the piston cylinder 31, and an L-shaped plate 32 is fixedly connected to the other end of the piston column 33.

[0023] After the filter screen ages or is damaged due to long-term use, the rotation speed of the servo motor 24 can be controlled to control the meshing distance between the gear 25 and the tooth groove 29 at the output end. When the second filter screen 22 moves to the left a certain distance, it will contact the L-shaped plate 32, thereby inserting the piston column 33 on the outside of the L-shaped plate 32 into the piston cylinder 31 on the right side of the horizontal plate 30, thereby causing the L-shaped plate 32 to retract, and causing one end of the L-shaped plate 32 to slide out from the groove inside the groove block 26, realizing the quick disassembly of the first mounting frame 20 and the internal filter screen.

[0024] Furthermore, springs 34 are fixedly connected to the bottom of the inner wall of the piston cylinder 31.

[0025] The spring 34 can extend and retract axially inside the piston cylinder 31, and the spring 34 maintains a vertically extended shape in its natural state, which can provide stable elastic support and reset driving force for the piston rod 33.

[0026] Furthermore, a groove block 26 is provided on the right side of the second filter screen 22, and a slider 36 is fixedly connected to the left side of the first filter screen 21. The outer side of the slider 36 is slidably connected to the inner side of the groove 35.

[0027] The slider 36 can slide and guide along the length of the slide groove 35, thereby realizing the positioning, assembly and relative sliding between the first filter screen 21 and the second filter screen 22, ensuring accurate alignment and smooth operation during filter screen assembly, and preventing deviation or jamming.

[0028] Furthermore, the tooth grooves 29 are opened in an equidistant manner.

[0029] The tooth grooves 29 are evenly distributed at equal intervals, and the spacing between each tooth groove 29 is consistent and the arrangement is regular, thereby ensuring smooth transmission with the gear 25 and avoiding jamming, jumping or transmission error caused by uneven spacing.

[0030] Furthermore, the brush 28 is cylindrical in shape.

[0031] The brush 28 has a cylindrical shape, which makes it easy to make full contact with the filter surface, achieving all-round and thorough cleaning. At the same time, the cylindrical shape can effectively reduce resistance and jamming during movement, improving cleaning stability and service life.

[0032] Furthermore, sealing rings are provided on the outer side of the piston rod 33.

[0033] The inner wall of the sealing ring on the outer side of the piston rod 33 fits tightly against the outer wall of the piston rod 33, thereby effectively preventing gas or dust from leaking from the fit gap between the piston rod 33 and the piston cylinder 31, ensuring the internal sealing and operational stability of the motion mechanism.

[0034] Furthermore, an exhaust port is provided on the outer side of the piston cylinder 31.

[0035] The exhaust port on the outside of the piston cylinder 31 can exhaust air and balance the air pressure in the internal cavity of the piston cylinder 31 when the piston rod 33 moves back and forth, so as to avoid excessive air pressure in the cavity and increase the resistance of piston movement.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 invention should be included within the protection scope of the present invention.
