Description

Technical Field

[0001] The utility model relates to the field of electronic engineering, in particular to a safety control cabinet. Background Art

[0002] With the rapid development of the Internet of Things, the application scope of electronic engineering is becoming wider and wider. Electronic engineering is mainly used for signal generation, information transmission, exchange and processing, as well as engineering applications in computer communication, digital communication, satellite communication, optical fiber communication, cellular communication, personal communication, stratospheric communication, multimedia technology, information highway, digital program-controlled switching, etc. In order to meet different levels of applications, multiple electronic communication equipment needs to be installed in the same control cabinet.

[0003] For example, the patent document with the announcement number CN218277564U discloses a safety control cabinet for electronic engineering. When the rotating block is separated from the circular groove, the stored spring force is released, so that the placement plate and the mounting plate slide on the limit rod through the sliding sleeves on both sides, and the placement plate and the mounting plate are moved to the outside of the cabinet, and then the electrical components on the placement plate and the mounting plate are transferred to a position convenient for maintenance personnel to facilitate maintenance. Since there is a lot of heat inside the control cabinet, the current control cabinets need to be equipped with a heat dissipation net on the side of the cabinet to ensure the normal operation of the electronic components. As the use time increases, dust on the heat dissipation net gradually accumulates, which is easy to affect the heat dissipation function. Manual regular cleaning will increase manpower consumption, and sometimes it is limited by the installation position of the control cabinet, and the cleaning of the heat dissipation net will be more troublesome.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 6As shown, a safety control cabinet includes a cabinet 1, a bracket 101 is arranged inside the cabinet 1, a mounting plate 102 is fixed on the front side of the bracket 101, and electronic components are all installed on the mounting plate 102. A translation mechanism 7 is arranged at the bottom end of the cabinet 1, and the translation mechanism 7 is used to drive the bracket 101 to move forward and backward. The translation mechanism 7 includes a slide rail 701, and the slide rail 701 is connected to the inner bottom wall of the cabinet 1 by screws. A slider 702 is slidably connected to the slide rail 701, and the bracket 101 is connected to the top of the slider 702 by screws. A screw rod 703 is installed on the top of the slide rail 701 through a bearing seat, and the screw rod 703 is threadedly connected to the slider 702. A handle 704 is welded to the front end of the screw rod 703. The slider 702 is driven forward by the rotation of the screw rod 703, and the slider 702 drives the bracket 101 to move forward, so that the electronic components on the mounting plate 102 are moved out from the front side of the cabinet 1, so as to facilitate maintenance by the staff.

[0026] A heat dissipation hole 103 is opened on one side of the cabinet 1, and an exhaust pipe 2 is connected to the heat dissipation hole 103 of the cabinet 1 by screws. An exhaust mechanism 3 and a dust screen 4 are arranged in the exhaust pipe 2. The dust screen 4 is rotatably installed in the exhaust pipe 2. A dust removal mechanism 5 is arranged in the exhaust pipe 2. The dust removal mechanism 5 includes an exhaust pipe 501. The exhaust pipe 501 is in a U-shape with an opening facing upward. The exhaust pipe 501 passes through the bottom end of the exhaust pipe 2. The two sides of the exhaust pipe 501 are located on both sides of the dust screen 4. The exhaust pipe 5 01 A brush 502 is provided on one side close to the dustproof net 4 and a dust suction hole 503 is opened. When the dustproof net 4 rotates, the brush 502 can sweep the dust on the dustproof net 4. An exhaust mechanism 6 is provided below the exhaust tube 2. The bottom end of the exhaust pipe 501 is connected to the exhaust mechanism 6. The exhaust mechanism 6 is used to form a negative pressure in the exhaust pipe 501, so that the swept dust is sucked into the exhaust pipe 501 through the dust suction hole 503, thereby avoiding dust accumulation in the exhaust pipe 501.

[0027] The dustproof net 4 includes an annular net 401, a swivel 402 is fixedly connected to the outside of the annular net 401, and the swivel 402 is rotatably installed on the inner wall of the exhaust duct 2. A mounting ring 403 is fixedly connected to the center of the annular net 401. The swivel 402 is used to support the annular net 401 and ensure that the annular net 401 rotates stably in the exhaust duct 2.

[0028] The exhaust mechanism 3 includes a support plate 301, which is connected to the exhaust tube 2 by screws. A rotating shaft 302 is connected to the support plate 301 through a bearing. One end of the rotating shaft 302 passes through the dustproof net 4 and is fixedly connected to an exhaust blade 303. The rotating shaft 302 is fixedly connected to the dustproof net 4. Specifically, the rotating shaft 302 is fixedly connected to the mounting ring 403. When the rotating shaft 302 rotates, it drives the mounting ring 403 to rotate, thereby causing the dustproof net 4 to rotate. At the same time, the rotating shaft 302 drives the exhaust blade 303 to rotate to discharge the heat inside the cabinet 1.

[0029] The exhaust mechanism 6 includes an exhaust cylinder 601, which is connected to the side of the cabinet 1 by screws. The exhaust cylinder 601 is connected to the exhaust pipe 501. A dual-axis motor 602 is arranged in the exhaust cylinder 601. The dual-axis motor 602 is connected to the side of the cabinet 1 by bolts. One output shaft of the dual-axis motor 602 is fixedly connected to an exhaust blade 603. The other output shaft of the dual-axis motor 602 extends into the interior of the cabinet 1 and is connected to a belt assembly 604. The output end of the belt assembly 604 is connected to the rotating shaft 302. The exhaust blade 603 is driven to rotate by the dual-axis motor 602. The exhaust blade 603 extracts the air from the exhaust pipe 501 to form a negative pressure in the exhaust pipe 501. At the same time, the dual-axis motor 602 drives the rotating shaft 302 to rotate through the belt assembly 604, thereby achieving the purpose of one machine with multiple uses.

[0030] The belt assembly 604 includes a driving pulley, a driven pulley and a belt. The driving pulley is fixedly connected to the output end of the dual-axis motor 602, and the driven pulley is fixedly connected to the rotating shaft 302. The belt connects the driving pulley and the driven pulley, and the diameter of the driving pulley is smaller than the diameter of the driven pulley. In this way, the exhaust blade 303 will not rotate too fast when the suction blade 603 rotates at a high speed. Since the exhaust blade 303 is used to extract the heat inside the cabinet 1, the exhaust blade 303 does not need to rotate too fast. In this way, the rotation speed of the dustproof net 4 will not be too fast, thereby ensuring the smooth rotation of the dustproof net 4.

[0031] An arc-shaped hole 504 is provided on one side of the exhaust pipe 501 close to the dustproof net 4, and the bottom surface of the arc-shaped hole 504 coincides with the inner wall of the bottom end of the exhaust tube 2. Since some of the dust on the dustproof net 4 will fall to the bottom of the exhaust tube 2, this part of the dust can be extracted through the arc-shaped hole 504 to ensure that a lot of dust will not accumulate inside the exhaust tube 2.

[0032] Working principle: When in use, the dual-axis motor 602 drives the rotating shaft 302 to rotate through the belt assembly 604, and the rotating shaft 302 drives the exhaust blades 303 and the mounting ring 403 to rotate. The exhaust blades 303 extract the heat inside the cabinet 1, and the mounting ring 403 drives the annular net 401 to rotate. The annular net 401 plays a role in dust prevention. As the annular net 401 rotates, the bristles 502 on the exhaust pipe 501 can sweep away the dust on the annular net 401, thus avoiding dust blockage. The annular net 401 ensures the ventilation and heat dissipation capacity of the annular net 401. The dual-axis motor 602 drives the exhaust blades 603 to rotate. The exhaust blades 603 extract the air in the exhaust pipe 501, so that a negative pressure is formed in the exhaust pipe 501, thereby sucking the dust into the exhaust pipe 501 through the dust suction holes 503 and the arc holes 504. The dust enters the exhaust cylinder 601 along the exhaust pipe 501 and is discharged. This can prevent dust from accumulating inside the exhaust cylinder 2 and achieve automatic dust cleaning.

[0033] When the electronic components on the mounting plate 102 need to be repaired, the staff holds the handle 704 and rotates the screw 703. The screw 703 drives the slider 702 to move forward, and the slider 702 drives the bracket 101 to move forward, so that the electronic components are moved to the outside of the cabinet 1, which makes it convenient for the staff to repair the electronic components.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
