Description

Technical Field

[0001] This invention relates to the field of network equipment technology, specifically to a network security equipment protection device. Background Technology

[0002] Network security equipment includes devices such as security routers, firewalls, security servers, and switches. Switches are more commonly used in daily network management and in companies or schools that need to install a large number of servers. Typically, multiple switches are stored together in a cabinet, which provides placement and protection for the switches and prevents dust from falling directly onto them.

[0003] Switches operate continuously for extended periods. While server racks provide protection, the heat generated by switches during prolonged operation dissipates slowly through the ventilation holes on the rack. To avoid affecting the normal operation of the switches, fans are currently used to draw outside air into the rack to cool them down.

[0004] While fans can remove hot air, over time, dust and cobwebs accumulate in the ventilation holes and fan vents, reducing the airflow area in and out of the cabinet. This affects heat dissipation and reduces the cabinet's protective effect. Summary of the Invention

[0005] Therefore, it is necessary to provide a network security device protection device to solve the problem that in the existing technology, the heat dissipation holes of the protection device of the switch become blocked after long-term use, resulting in the inability to dissipate heat and a decrease in the protection effect of the switch.

[0006] This application provides a network security device protection device, including: a protective box, the front end of which is provided with a glass door via a hinge.

[0007] The protective box has two symmetrical vertical slots on both the left and right ends. Multiple vertical blocks are slidably arranged in the vertical slots. The vertical blocks on the same layer are fixedly mounted on a mounting plate for installing and placing the switch. Multiple ventilation holes are arranged in a matrix on the mounting plate.

[0008] The protective box is equipped with a heat dissipation mechanism, which includes air inlet units located on the upper and lower ends of the protective box and air outlet units located on the left and right ends of the protective box.

[0009] An auxiliary cleaning mechanism is provided on the left and right end faces and the lower end face of the protective box for cleaning the heat dissipation mechanism.

[0010] The air outlet unit includes an air outlet slot. Both the left and right ends of the protective box are provided with air outlet slots. An air outlet plate is fixedly installed between the front and rear inner walls of the air outlet slot. Multiple air outlets are arranged in a matrix on the side of the air outlet plate. The protective box is provided with cleaning units that correspond one-to-one with the air outlet plates. The two cleaning units are symmetrically distributed.

[0011] The cleaning unit includes a block-moving groove. The inner wall of the right-side air outlet has block-moving grooves on both the front and rear ends, running from top to bottom. Two electric sliders are slidably mounted within the block-moving grooves. Placement plates are fixedly mounted on the opposite faces of the two electric sliders. Horizontal grooves are opened on the opposite faces of the two placement plates. Sliding blocks are slidably mounted within the horizontal grooves. A hanging plate is fixedly mounted between the two sliding blocks. A cylindrical top block, corresponding to the air outlet in the same row, is fixedly mounted on the right end face of the hanging plate. The right end of the top block has rounded corners, its diameter is smaller than the diameter of the air outlet, and it is made of rubber. A drive assembly for driving the top blocks to perform cleaning is mounted on the air outlet plate, and the drive assembly is symmetrically distributed from left to right.

[0012] According to an advantageous embodiment, the drive assembly includes fixing strips. Multiple magnetic fixing strips are fixedly arranged at equal intervals from front to back on the left end face of the right-side air outlet plate. Fixing blocks, corresponding one-to-one with the fixing strips and possessing the same magnetism, are fixedly arranged on the right end face of the suspension plate. A transverse plate is fixedly arranged on the right end face of the protective box cavity. Multiple semi-circular plates, arranged at equal intervals and corresponding one-to-one with adjacent air outlets, are fixedly arranged on the front end face of the transverse plate, with the arc-shaped surface of the semi-circular plates facing to the right. A mating plate, which cooperates and presses against the semi-circular plates, is fixedly arranged on the opposite side of the suspension plate and the semi-circular plates.

[0013] According to an advantageous embodiment, the air intake unit includes an air inlet, and the upper and lower end faces of the protective box are provided with a plurality of air inlets arranged in a matrix and communicating with their inner cavity. An air intake fan is provided inside the air inlet, and the upper and lower end faces of the protective box are provided with filters corresponding to the air inlets one by one. The upper end face of the protective box is fixedly provided with a baffle plate corresponding to the upper air inlet one by one by a fixing column.

[0014] According to an advantageous embodiment, a protective cover with an internal cavity is fixedly provided on the lower end face of the protective box. A rectangular groove corresponding to the lower air inlet is opened on the lower end face of the protective cover. Multiple rotating shafts arranged at equal distances are rotatably arranged between the front and rear inner walls of the rectangular groove. An S-shaped shielding member is fixedly sleeved on the rotating shaft, and two adjacent shielding members cooperate with each other.

[0015] According to an advantageous embodiment, the drive assembly includes a fixed bar, a sprocket is fixedly sleeved on the rotating shaft, all sprockets in the same rectangular groove are interconnected and cooperate with each other by a transmission chain, and two left-right symmetrical slider grooves are opened on the lower end face of the protective cover. An electric slider is slidably arranged in the slider groove, and a connecting bar corresponding to the corresponding transmission chain on the same side is fixedly arranged on the lower end face of the electric slider through a rectangular plate, and the connecting bar is fixedly connected to the corresponding transmission chain.

[0016] According to an advantageous embodiment, the auxiliary cleaning mechanism includes a first cleaning unit, a second cleaning unit, and a threaded shaft. The first cleaning unit includes a through groove. Both the left and right end faces of the protective box are provided with through grooves that communicate with the corresponding sliding block grooves on the rear side. A vertical plate that is fixedly connected to the corresponding electric slider is slidably arranged in the through groove. An arc-shaped scraper is fixedly arranged on the front end face of the vertical plate, and the outer arc surface of the arc-shaped scraper is in close contact with the air outlet plate.

[0017] According to an advantageous embodiment, the second cleaning unit includes a rotating shaft. The lower end face of the protective box is rotatably provided with the rotating shaft penetrating the protective cover. The circumferential surface of the rotating shaft is fixedly provided with a scraper with arc-shaped surfaces on both the left and right ends. The right arc-shaped surface of the scraper is rotatably provided with a mounting shaft through ear seats distributed front and rear. A cleaning roller for cleaning the lower air inlet is fixedly installed on the mounting shaft. The circumferential surface of the cleaning roller is fixedly provided with a plurality of circumferentially evenly distributed brushes.

[0018] According to an advantageous embodiment, the lower end face of the inner cavity of the protective box is rotatably provided with a threaded shaft that passes through its upper end, and the threaded shaft and the mounting plate are threadedly engaged.

[0019] In summary, the present invention has at least one of the following beneficial effects: First, in the present invention, the top block is fully inserted into the corresponding air outlet, thereby pushing out the spider webs and dust and other impurities attached to the inner wall of the air outlet. At the same time, the vertical plate drives the arc-shaped scraper to move down, so that the arc-shaped scraper scrapes the surface of the air outlet plate, thereby cleaning the impurities pushed out after the top block and the air outlet cooperate, ensuring the unobstructed air outlet.

[0020] Second, the rotating shaft drives the scraper to scrape and clean the filter screen on the lower side, and the cleaning roller with the corresponding brush brushes the filter screen. At the same time, the electric slider works here, which drives the connecting strip to move back and forth through the rectangular plate, causing the shield to swing. This makes it easy for the dust that is brushed off the filter screen on the lower side to fall out of the protective cover and fall to the ground, thus ensuring that the air inlet is not blocked and ensuring stable heat dissipation of the switch protection device.

[0021] Third, the mounting plate is moved up by the threaded engagement between the threaded shaft and the mounting plate. At this time, the bottom mounting plate maintains a distance from the air inlet on the lower side of the protective box. At the same time, the different distances the connecting strip moves allow the shielding parts to rotate at different angles, reducing the air intake of the lower air inlet. Therefore, the air in the protective box mainly enters through the upper air inlet, thereby reducing the impact of ground moisture on the switch on the mounting plate. Attached Figure Description

[0045] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] like Figure 1 , Figure 2 and Figure 6 As shown, a network security device protection device includes: a protective box 1, which is a box with an open front end and an internal cavity. The lower end face of the protective box 1 is provided with four casters arranged in a matrix, and the front end face of the protective box 1 is provided with a glass door by hinge.

[0047] Vertical groove 2: Two symmetrical vertical grooves 2 are opened on both the left and right end faces of the inner cavity of the protective box 1. Multiple vertical blocks 20 are slidably arranged in the vertical groove 2. The vertical blocks 20 on the same layer are fixedly arranged with a mounting plate 21 for installing and placing the switch. Multiple ventilation holes 210 arranged in a matrix are opened on the mounting plate 21.

[0048] The heat dissipation mechanism 3 is provided on the protective box 1. The heat dissipation mechanism 3 includes an air inlet unit 30 located on the upper and lower end faces of the protective box 1 and an air outlet unit 31 located on the left and right end faces of the protective box 1.

[0049] The auxiliary cleaning mechanism 4 is provided on the left and right end faces and the lower end face of the protective box 1 for cleaning the heat dissipation mechanism 3 and adjusting and controlling the mounting plate 21.

[0050] The air intake unit 30 includes an air inlet 300. The upper and lower end faces of the protective box 1 are provided with multiple air inlets 300 arranged in a matrix and communicating with their inner cavities. An air intake fan 301 is provided inside the air inlet 300. The upper and lower end faces of the protective box 1 are provided with a filter screen 302 corresponding to the air inlet 300. The upper end face of the protective box 1 is fixedly provided with a baffle plate 303 corresponding to the upper air inlet 300 by a fixing column.

[0051] The air outlet unit 31 includes an air outlet slot 310. Both the left and right ends of the protective box 1 are provided with air outlet slots 310. An air outlet plate 311 is fixedly installed between the front and rear inner walls of the air outlet slot 310. Multiple air outlets 312 are arranged in a matrix on the side of the air outlet plate 311. The protective box 1 is provided with cleaning units that correspond one-to-one with the air outlet plate 311. The two cleaning units are symmetrically distributed.

[0052] The switch to be installed is manually placed on the mounting plate 21. The intake fan 301, located in the air inlet 300, is powered on, allowing air from the top and bottom sides of the protective box 1 to enter the protective box 1. The filter 302 installed here blocks larger debris and dust from the outside. The baffle 303 installed here covers the upper air inlet 300 and the filter 302 to prevent dust from entering the protective box 1 and affecting the normal operation of the switch. The air blown in by the intake fan 301 comes into contact with the installed switch through the ventilation holes 210 on the mounting plate 21 and the gaps around the mounting plate 21, and carries away the heat generated by the switch during operation. Finally, it flows out through the air outlets 312 on the left and right side air outlets 311, thereby achieving heat dissipation for the switch.

[0053] like Figure 2 and Figure 3 As shown, a protective cover 32 with an internal cavity is fixedly installed on the lower end face of the protective box 1. A rectangular groove 320 corresponding to the lower air inlet 300 is opened on the lower end face of the protective cover 32. Multiple rotating shafts 321 arranged at equal distances are rotatably arranged between the front and rear inner walls of the rectangular grooves 320. An S-shaped shielding member 322 is fixedly sleeved on the rotating shaft 321, and two adjacent shielding members 322 cooperate with each other.

[0054] like Figure 2 and Figure 3 As shown, a sprocket 323 is fixedly sleeved on the rotating shaft 321. All sprockets 323 in the same rectangular groove 320 are connected and cooperate with each other through a transmission chain. The lower end face of the protective cover 32 has two left-right symmetrical slider grooves 324. An electric slider is slidably arranged in the slider groove 324. The lower end face of the electric slider is fixedly provided with a connecting strip 325 corresponding to the transmission chain on the same side through a rectangular plate, and the connecting strip 325 is fixedly connected to the corresponding transmission chain.

[0055] During operation, the electric slider moves the connecting bar 325 via the rectangular plate. The connecting bar 325 then moves the corresponding front and rear transmission chains. Through the cooperation between the transmission chains and the corresponding sprockets 323, the rotating shaft 321 causes the corresponding shielding member 322 on it to rotate at a certain angle. Therefore, the two adjacent shielding members 322 cooperate with each other, meaning that the two adjacent shielding members 322 have an overlapping area when viewed from above, thereby achieving the shielding effect on the internal air inlet 300. At the same time, it does not affect the air entering the protective box 1 through the protective cover 32. By moving the connecting bar 325 a different distance, the shielding member 322 rotates at different angles, thus controlling the air intake at the bottom. When the switch is working in hot weather such as summer, the movement of the connecting bar 325 makes all the shielding members 322 vertically arranged, at which time the air intake is maximized, meeting the heat dissipation requirements of the switch.

[0056] like Figure 9 , Figure 10 and Figure 11 As shown, taking the cleaning unit on the right as an example, the cleaning unit on the right includes a moving block groove 33. The front and rear end faces of the inner wall of the air outlet 312 on the right are provided with moving block grooves 33 from top to bottom. Electric sliders are slidably arranged in the moving block grooves 33. Placement plates 330 are fixedly arranged on the opposite faces of the two electric sliders 2. Horizontal grooves 331 are opened on the opposite faces of the two placement plates 330. Sliding blocks are slidably arranged in the horizontal grooves 331. A hanging plate 332 is fixedly arranged between the two sliding blocks. A cylindrical top block 333 corresponding to the air outlets 312 in the same row is fixedly arranged on the right end face of the hanging plate 332. The right end of the top block 333 is rounded. The diameter of the top block 333 is smaller than the diameter of the air outlet 312. The top block 333 is made of rubber. A drive group for driving the top block 333 to perform cleaning is provided on the air outlet plate 311. The drive group is symmetrically distributed on the left and right sides.

[0057] Taking the drive group on the right as an example, the drive group on the right includes a fixing strip 334. The left end face of the air outlet plate 311 on the right is fixedly provided with a plurality of fixing strips 334 arranged at equal distances from front to back and having magnetic properties. The right end face of the suspension plate 332 is fixedly provided with a fixing block 335 that corresponds one-to-one with the fixing strips 334 and has the same magnetic properties as the fixing strips 334. The right end face of the inner cavity of the protective box 1 is fixedly provided with a transverse plate 336. The front end face of the transverse plate 336 is fixedly provided with a plurality of semi-circular plates 337 arranged at equal distances and corresponding one-to-one with the adjacent air outlets 312. The arc surface of the semi-circular plate 337 faces to the right. The opposite face of the suspension plate 332 and the semi-circular plate 337 is fixedly provided with a mating plate 338 that cooperates and presses against the semi-circular plate 337. The shape of the mating plate 338 is the same as the shape of the semi-circular plate 337.

[0058] During operation, the electric slider 2 moves the placement plate 330 downwards, which in turn moves the sliding block and the suspension plate 332. The lower half of the arc-shaped surface of the mating plate 338 on the suspension plate 332 begins to contact the upper half of the arc-shaped surface of the semi-circular plate 337. Simultaneously, the semi-circular plate 337 begins to press against the mating plate 338, causing the mating plate 338 to move the suspension plate 332 closer to its adjacent air outlet plate 311. At this point, the top block 333 is inserted into the corresponding air outlet 312. When the mating plate 338 exerts no vertical pressing force on the semi-circular plate 337 (i.e., the two are only in close contact), the top block 333 is fully inserted into the corresponding air outlet 312. Afterwards, the electric slider 2 continues to move the placement plate 330 downwards. As the plate moves downward, the fixing block 335 on the hanging plate 332 gradually moves away from the corresponding fixing strip 334 under the action of magnetism. During this process, the upper half of the mating plate 338 fits tightly with the lower half of the corresponding semicircular plate 337, causing the fixing block 335 to drive the hanging plate 332 closer to the adjacent semicircular plate 337. Thus, the hanging plate 332, along with the top block 333, exits the corresponding air outlet 312. Then, the mating plate 338 continues to fit with the next semicircular plate 337, and the top block 333 continues to repeat the above operation to push into the next row of air outlets 312. During this process, the top block 333 pushes out the cobwebs, dust, and other impurities attached to the inner wall of the air outlet 312, making it easier for subsequent cleaning.

[0059] like Figure 6 and Figure 7 As shown, the auxiliary cleaning mechanism 4 includes a first cleaning unit 40, a second cleaning unit 41, a threaded shaft 42, and a control unit 43. The first cleaning unit 40 includes a through groove 400. Both the left and right ends of the protective box 1 are provided with through grooves 400 that communicate with the corresponding sliding block grooves 33 on the rear side. A vertical plate 401 that is fixedly connected to the corresponding electric slider 2 is slidably arranged in the through groove 400. An arc-shaped scraper 402 is fixedly arranged on the front end face of the vertical plate 401, and the outer arc surface of the arc-shaped scraper 402 is in close contact with the air outlet plate 311.

[0060] like Figure 4 and Figure 5 As shown, the second cleaning unit 41 includes a rotating shaft 410. The lower end face of the protective box 1 is rotatably provided with the rotating shaft 410 that passes through the protective cover 32, and the rotating shaft 410 is connected to an external motor (not shown in the figure). The circumferential surface of the rotating shaft 410 is fixedly provided with a scraper 411 whose left and right end faces are both arc-shaped. The right arc-shaped surface of the scraper 411 is rotatably provided with a mounting shaft 412 through ear seats distributed in front and behind. A cleaning roller 413 for cleaning the lower air inlet 300 is fixedly installed on the mounting shaft 412. The circumferential surface of the cleaning roller 413 is fixedly provided with a plurality of circumferentially evenly distributed brushes.

[0061] During operation, when the electric slider 2 moves the placement plate 330 downward, and when the mating plate 338 does not exert vertical pressure on the semi-circular plate 337, the semi-circular plate 337 and the mating plate 338 cooperate to push the top block 333 into the air outlet 312. At this time, the vertical plate 401 moves the arc-shaped scraper 402 downward, thus scraping the surface of the air outlet plate 311 to remove impurities pushed out of the air outlet 312 by the top block 333, ensuring the air outlet 312 remains unobstructed. Meanwhile, the external motor 1 drives the rotating shaft 41... Rotating shaft 410 drives scraper 411 to scrape and clean the filter screen 302 on the lower side. The cleaning roller 413 with brushes brushes the filter screen 302. At the same time, the electric slider moves the connecting strip 325 back and forth through the rectangular plate, causing the shield 322 to swing. This allows the dust that falls off the cleaning brush on the filter screen 302 to fall out of the protective cover 32 and onto the ground. After that, only the ground needs to be cleaned manually, thus ensuring that the air inlet 300 is not blocked and ensuring stable heat dissipation of the internal exchanger.

[0062] like Figure 6 As shown, a threaded shaft 42 is rotatably provided on the lower end face of the inner cavity of the protective box 1, which passes through the upper end of the shaft. After passing through the upper end of the protective box 1, the threaded shaft 42 is connected and engaged with an external motor (not shown in the figure). The threaded shaft 42 and the mounting plate 21 are threadedly engaged. A control unit 43 for controlling the position of the mounting plate 21 is provided on the right end face of the inner cavity of the protective box 1.

[0063] like Figure 6 and Figure 8 As shown, multiple control units 43 are arranged from top to bottom. Each control unit 43 includes a mounting block 430. The mounting block 430 is fixedly installed on the right end face of the inner cavity of the protective box 1. A movable column 431 is movably installed on the mounting block 430. A support block 432 is fixedly installed on the rear end face of the movable column 431. The rear end of the support block 432 is an isosceles trapezoidal structure. A first spring 433 is provided between the support block 432 and the corresponding mounting block 430. The first spring 433 is sleeved on the outside of the movable column 431. A trapezoidal block 434 with a downward inclined surface is fixedly installed on the front end face of the movable column 431. A receiving slot 435 corresponding to the mounting block 430 is opened on the right end face of the inner cavity of the protective box 1. An electric slider 3 is slidably installed in the receiving slot 435. A mating block 436 with an inclined surface that is in close contact with the inclined surface of the trapezoidal block 434 and is a right-angled trapezoid is fixedly installed on the left end face of the electric slider 3.

[0064] When the ground below the protective box 1 becomes damp during rainy or humid weather, the external motor 2 drives the threaded shaft 42 to rotate. The threaded engagement between the threaded shaft 42 and the mounting plate 21 causes the mounting plate 21 to move upward. At this time, the lowermost mounting plate 21 maintains a certain distance from the air inlet 300 on the lower side of the protective box 1. Simultaneously, the different distances the connecting strip 325 moves allow the shielding member 322 to rotate at different angles, reducing the air intake of the lower air inlet 300. Therefore, the air inside the protective box 1 mainly enters through the upper air inlet 300, thereby reducing the impact of ground dampness on the switch on the mounting plate 21.

[0065] During the movement of the mounting plate 21, the electric slider 3 first drives the mating block 436 to move upward. Through the cooperation between the mating block 436 and the trapezoidal block 434, the trapezoidal block 434 drives the moving column 431 to move forward, so that the inclined surface of the support block 432 can contact the vertical block 20. During the upward movement of the mounting plate 21, the support block 432 is pushed forward, and the first spring 433 is compressed. When the mounting plate 21 moves to the upper surface of the support block 432, the vertical block 20 no longer contacts the inclined surface of the support block 432 and the electric slider 3 does not move, so that the horizontal surface of the support block 432 contacts the corresponding vertical block 20 and provides support for the vertical block 20.
