Description

Technical Field

[0001] The present invention belongs to the technical field of computer chassis, and specifically relates to a computer security protection chassis device. Background Art

[0002] The security protection of large computer chassis is extremely important and covers multiple key aspects; in terms of heat dissipation, air cooling and water cooling technologies are used. By optimizing the air duct and coolant circulation, combined with intelligent temperature control, the temperature of core components is ensured to be stable; in terms of physical protection, the chassis is made of high-strength materials, with a strong shell and tight locks to prevent external collisions and malicious openings; at the electromagnetic shielding level, special metal materials and structural designs effectively block electromagnetic interference and avoid information leakage; multiple protection mechanisms work together to provide a solid guarantee for the stable operation of large computers, data security and the service life of hardware, ensuring its reliable operation in complex environments.

[0003] In the prior art, the heat dissipation and ventilation of a computer usually discharge the heat generated inside the chassis through the air duct formed by multiple cooling fans. However, the heat dissipation effect of traditional cooling fans has an upper limit. When there is dust inside the computer hardware or the computer has been used for a long time, the energy consumption of the hardware increases, resulting in an increase in the generated heat. The air duct provided by the cooling fans cannot meet the demand, leading to an increase in the temperature inside the chassis; moreover, the heat generated by each computer hardware lacks targeted and relatively precise heat dissipation structures, and the air duct formed by multiple cooling fans cannot accurately take away the heat in the proximal end of the hardware in time, making it difficult to reduce the temperature inside the chassis in a short time. As a result, the operation of the computer is affected. Therefore, the present invention provides a computer security protection chassis device. Summary of the Invention

[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Embodiment 1

[0033] As Figures 1 to 11As shown in the figure, a computer security protection chassis device according to an embodiment of the present invention includes a box body 1. A heat dissipation box 11 is fixedly connected to the side wall of the box body 1 through a fixed groove. A set of ventilation slots I and ventilation slots II are provided on both side walls of the heat dissipation box 11. A ventilation round tube 12 is fixedly connected between a pair of ventilation slots I, and a Venturi tube 13 is fixedly connected between a pair of ventilation slots II. A wind guide cover 14 is fixedly connected to the side wall of the heat dissipation box 11 inside the box body 1. A rotating shaft 15 is rotatably connected to the side wall of the heat dissipation box 11. A set of heat dissipation blades 151 are fixedly connected to the rotating shaft 15. A rotating ring 16 is provided at the end of the wind guide cover 14. A ring cover 17 is fixedly connected between the outer circular wall of the rotating ring 16 and the wind guide cover 14. A sealing cover 18 is fixedly connected between the end of the ring cover 17 and the side wall of the heat dissipation box 11. A series connection tube 19 is fixedly connected between the throats of a set of Venturi tubes 13. A set of series connection tubes 19 all pass through the sealing cover 18 and penetrate through the ring cover 17. An air suction cover 191 is fixedly connected between a set of series connection tubes 19. A set of rotating plates 2 are provided on the side wall of the heat dissipation box 11. A switching component is provided on the side wall of the heat dissipation box 11. The rotation of the rotating plate 2 is driven by the switching component. During operation, heat is generated when the computer box body 1 is running. The rotation of the rotating shaft 15 and the heat dissipation blades 151 is powered by the computer power supply. The heat dissipation blades 151 selectively discharge the hot gas from the ventilation round tube 12 or the Venturi tube 13. When the heat in the chassis is at a normal stage, it is discharged through the ventilation round tube 12. When the temperature inside the chassis is relatively high, it is discharged through the Venturi tube 13. At the same time, when the gas is discharged from the Venturi tube 13, the air pressure in its throat is relatively low, which causes the series connection tube 19 connected to the throat to suck the hot gas through the air suction cover 191. Moreover, a set of series connection tubes 19 and air suction covers 191 can extend to various positions inside the chassis, forming multiple sets of series connection tubes 19 and air suction covers 191 to perform targeted heat discharge at close range on the positions with high energy consumption inside the chassis, thereby more effectively reducing the inside of the chassis, thus avoiding damage to the hardware inside the chassis or affecting the operating speed of the host computer.

[0034] The switching component includes a power unit and fixed blocks. Fixed blocks are fixedly connected to the top and bottom side walls of the heat dissipation box 11 inside the air guide cover 14. A rotating shaft 21 is rotatably connected between a pair of the fixed blocks, and the rotating shaft 21 penetrates upward through the fixed blocks. Rotating plates 2 are fixedly connected to each of the group of rotating shafts 21. The ventilation circular pipe 12 and the Venturi tube 13 are arranged at intervals and crosswise. The rotating plates 2 correspond to the positions of the adjacent Venturi tubes 13 and ventilation circular pipes 12. Sealing gaskets are fixedly connected to both side walls of the rotating plates 2. During operation, the power unit provides power for the rotation of the rotating plates 2. The rotating plates 2 are installed on the rotating shafts 21. When the rotating shafts 21 drive the rotating plates 2 to rotate, it is possible to choose to block the Venturi tubes 13 or the ventilation circular pipes 12. However, when the temperature inside the chassis is normal, the Venturi tubes 13 are blocked by the rotating plates 2. Conversely, the ventilation circular pipes 12 are blocked. When the external environment is harsh and seriously affects the temperature inside the chassis, the rotating plates 2 are positioned between the ventilation circular pipes 12 and the Venturi tubes 13, and the ventilation circular pipes 12 and the Venturi tubes 13 are used to discharge hot gases simultaneously. At this time, the rotation speed of the heat dissipation blades 151 needs to be faster, and the power consumption increases. When the temperature inside the chassis is normal, only the heat dissipation gas is discharged through the ventilation circular pipes 12. At this time, the energy consumption required for the rotation of the heat dissipation blades 151 is reduced. This design can select the heat dissipation method according to the temperature inside the chassis, thereby avoiding the problem of increased energy consumption caused by the long-term single use of the Venturi tubes 13.

[0035] The power unit includes gears 22. Gears 22 are fixedly connected to the top ends of each of the group of rotating shafts 21. A guide plate 23 is fixedly connected to the top of the heat dissipation box 11. A micro-push rod 24 is fixedly connected to the inner side wall of the box body 1. The piston rod end of the micro-push rod 24 is fixedly connected to a rack plate 25. A sliding groove is formed at the bottom of the rack plate 25, and the guide plate 23 is slidably connected in the sliding groove. The rack plate 25 meshes with the group of gears 22. During operation, the micro-push rod 24 is started, and the rack plate 25 at the piston rod end moves under the guiding action of the guide plate 23. When the rack plate 25 moves, it drives the gears 22 to rotate, and then the rotating shafts 21 fixedly connected to the gears 22 rotate, finally realizing the rotation of the rotating plates 2 to adjust the ventilation states of the ventilation circular pipes 12 and the Venturi tubes 13.

[0036] Embodiment 2

[0037] As Figures 1 to 11As shown, annular grooves are provided on each of the series pipes 19 within a set of the shroud 17; a filter screen 3 is fixedly connected between the inner circular wall of the shroud 17 and the outer circular wall of the air guide cover 14. The cross-section of the filter screen 3 is V-shaped, and the V-shaped side at the proximal end of the inner circular wall of the shroud 17 is shorter. The V-shaped opening of the filter screen 3 faces the air suction cover 191. The air guide cover 14 is rotatably connected to the rotating ring 16, and the rotating ring 16 is fixedly connected to the rotating shaft 15 through a set of fixing rods; a set of air guide blocks 31 are fixedly connected to the outer circular wall of the rotating ring 16. The cross-section of the air guide block 31 is a quasi-right-angled triangle and is twisted. The inclined surface of the air guide block 31 faces the V-shaped short side of the filter screen 3. During operation, hot gas is specifically sucked through the throat of the Venturi tube 13 and the series pipe 19, enters the Venturi tube 13 after being filtered by dust through the shroud 17 and the filter screen 3, and is finally discharged from the box body 1; the filter screen 3 can filter impurities such as dust in the air flow. The V-shaped design of the filter screen 3 increases the filtering area, and the gas is affected by the air guide block 31, increasing the probability of it entering the V-shaped short side of the filter screen 3. As a result, dust accumulates at the V-shaped short side and the bent part of the filter screen 3, while ventilation can still be carried out at the V-shaped long side of the filter screen 3, avoiding the problem of reduced ventilation efficiency of the filter screen 3 caused by dust blockage and also preventing dust from entering the Venturi tube 13 and causing blockage inside the tube; when the rotating shaft 15 rotates, the rotating ring 16 is driven to rotate through the fixing rod, and the air guide block 31 on the rotating ring 16 rotates accordingly. The air guide block 31 is a twisted quasi-right-angled triangle, and its inclined surface faces the V-shaped short side of the filter screen 3, which can guide the air flow to pass through the filter screen 3 more dispersedly, improving the filtering effect.

[0038] A pair of fixing blocks are fixedly connected to the outer circular wall of the rotating ring 16. A first shaft is fixedly connected between the pair of fixing blocks. A guiding rod 41 is rotatably connected to the first shaft. A guiding groove 42 is provided on the inner circular wall of the shroud 17, and the guiding rod 41 is slidably connected in the guiding groove 42. A cleaning brush 43 is fixedly connected to the guiding rod 41. During operation, the rotating ring 16 rotates, driving the fixing blocks and the connecting shaft to rotate, so that the guiding rod 41 slides in the guiding groove 42 on the inner circular wall of the shroud 17, and the cleaning brush 43 on the guiding rod 41 cleans the filter screen 3 as the guiding rod 41 slides, preventing the filter screen 3 from being blocked and ensuring the ventilation effect.

[0039] Embodiment Three

[0040] As Figures 1 to 11As shown, the guiding groove 42 is composed of circular grooves 5 and arc grooves 51 connected at intervals. A set of wave grooves 52 are formed in each set of arc grooves 51, and the wave grooves 52 are adapted to the guide rods 41. During operation, the guide rods 41 slide in the circular grooves 5 and arc grooves 51 of the guiding groove 42. When the guide rods 41 slide in the wave grooves 52 in the arc grooves 51, the dust on the cleaning brush 43 will receive vibrations, causing the dust on its surface to fall off by shaking, preventing dust accumulation and adhesion on the cleaning brush 43, thereby affecting the performance of the cleaning brush 43 and making it easier for the dust attached to the filter screen 3 to fall off.

[0041] A pair of blocking bars 6 are fixedly connected between the filter screen 3 and the ring cover 17, and the blocking bars 6 are located on the proximal side of the cleaning brush 43. A through groove is formed at the top of the box body 1, and the through groove is connected to the inside of the ring cover 17. A micro vacuum cleaner 61 is fixedly connected to the top of the through groove through a connecting pipe, and the micro vacuum cleaner 61 is fixedly connected to the top of the box body 1. During operation, the blocking bars 6 are located on the proximal side of the cleaning brush 43, which can prevent the cleaned dust from reattaching to other parts of the filter screen 3. The bristles of the cleaning brush 43 are elastic. Due to the blocking of the blocking bars 6, the bristles of the cleaning brush 43 are deformed, causing the impurities and dust inside to fall into the ring cover 17. When the micro vacuum cleaner 61 is started, the dust cleaned in the ring cover 17 can be sucked away to keep the inside of the ring cover 17 clean. The dust and impurities blocked by the blocking bars or fallen due to the vibration of the wave grooves 52 will drive the gas to generate a circulating air flow under the condition that the air guiding blocks 31 rotate with the rotating ring 16, so that the dust and impurities circulate in the ring cover 17 and are more easily sucked away by the micro vacuum cleaner 61.

[0042] A set of ventilation grooves 7 are formed on the inclined surfaces of each set of air guiding blocks 31. A sound insulation pad is provided in the heat dissipation box 11. During operation, the ventilation grooves 7 on the inclined surfaces of the air guiding blocks 31 can further optimize the flow of the air flow, making the air flow pass more smoothly around the air guiding blocks 31, improving the ventilation efficiency, and thus enhancing the heat dissipation effect of the entire heat dissipation system.

[0043] Working principle: During the operation of the computer case 1, heat is generated. The rotation of the rotating shaft 15 and the cooling fins 151 is powered by the computer power supply. The cooling fins 151 selectively discharge the hot gas from the ventilation round tube 12 or the Venturi tube 13. When the heat in the case is at a normal stage, it is discharged through the ventilation round tube 12. When the temperature inside the case is relatively high, it is discharged through the Venturi tube 13. At the same time, when the gas is discharged from the Venturi tube 13, the air pressure in its throat is relatively low, which causes the series tube 19 connected to the throat to suck the hot gas through the suction hood 191. Moreover, a group of series tubes 19 and suction hoods 191 can extend to various positions inside the case, forming multiple groups of series tubes 19 and suction hoods 191 to perform targeted heat discharge at close range on the positions with high energy consumption inside the case, thereby more effectively reducing the inside of the case, avoiding damage to the hardware inside the case or affecting the operating speed of the host. The power unit provides power for the rotation of the rotating plate 2. The rotating plate 2 is installed on the rotating shaft 21. When the rotating shaft 21 drives the rotating plate 2 to rotate, it can choose to block the Venturi tube 13 or the ventilation round tube 12. When the temperature inside the case is normal, the Venturi tube 13 is blocked by the rotating plate 2, and vice versa. When the external environment is harsh and seriously affects the temperature inside the case, the rotating plate 2 is positioned between the ventilation round tube 12 and the Venturi tube 13, and the ventilation round tube 12 and the Venturi tube 13 are used to discharge the hot gas at the same time. At this time, the rotation speed of the cooling fins 151 needs to be faster, and the power consumption increases. When the temperature inside the case is normal, only the heat gas is discharged through the ventilation round tube 12. At this time, the energy consumption required for the rotation of the cooling fins 151 is reduced. This design can select the heat discharge method according to the temperature inside the case, thereby avoiding the problem of increased energy consumption caused by the long-term single use of the Venturi tube 13. The micro push rod 24 is activated, and the rack plate 25 at the end of its piston rod moves under the guiding action of the guide plate 23. When the rack plate 25 moves, it drives the gear 22 to rotate, and then the rotating shaft 21 fixed to the gear 22 rotates, finally realizing the rotation of the rotating plate 2 to adjust the ventilation state of the ventilation round tube 12 and the Venturi tube 13. The hot gas is targeted and sucked through the throat of the Venturi tube 13 and the series tube 19, enters the Venturi tube 13 after passing through the ring cover 17 and the filter screen 3 to filter dust, and is finally discharged from the case 1. The filter screen 3 can filter dust and other impurities in the air flow. The design of the V-shaped filter screen 3 increases the filtering area, and the gas is affected by the air guiding block 31, increasing the probability of entering the short side of the V-shaped filter screen 3, so that dust accumulates at the short side and the bending part of the V-shaped filter screen 3, while the long side of the V-shaped filter screen 3 can still ventilate, avoiding the problem of reduced ventilation efficiency of the filter screen 3 caused by dust blockage and at the same time preventing dust from entering the Venturi tube 13 and causing blockage inside the tube;When the rotating shaft 15 rotates, it drives the rotating ring 16 to rotate through the fixed rod. The air guiding block 31 on the rotating ring 16 rotates accordingly. The air guiding block 31 is in the shape of a distorted right-angled triangle, and its inclined surface faces the short side of the V shape of the filter screen 3, which can guide the airflow to pass through the filter screen 3 more dispersedly, improving the filtering effect. When the rotating ring 16 rotates, it drives the fixed block and the connecting shaft to rotate, so that the guiding rod 41 slides in the guiding groove 42 on the inner circular wall of the ring cover 17. The cleaning brush 43 on the guiding rod 41 cleans the filter screen 3 as the guiding rod 41 slides, preventing the filter screen 3 from being blocked and ensuring the ventilation effect. The guiding rod 41 slides in the circular groove 5 and the arc groove 51 of the guiding groove 42. When the guiding rod 41 slides in the wave groove 52 of the arc groove 51, the dust on the cleaning brush 43 will receive vibration, causing the dust on its surface to fall off by shaking, avoiding dust accumulation and adhesion on the cleaning brush 43, which will affect the performance of the cleaning brush 43, making the dust attached to the filter screen 3 easier to fall off. The blocking bar 6 is located on one side of the proximal end of the cleaning brush 43, which can prevent the cleaned dust from reattaching to other parts of the filter screen 3. The bristles of the cleaning brush 43 are elastic. Due to the blocking of the blocking bar 6, the bristles of the cleaning brush 43 are deformed, causing the impurities and dust inside to fall into the ring cover 17; when the mini vacuum cleaner 61 is started, it can suck away the dust cleaned in the ring cover 17, keeping the inside of the ring cover 17 clean. And the dust and impurities blocked by the blocking bar or fallen due to the vibration of the wave groove 52 will drive the gas to generate a circulating air direction when the air guiding block 31 rotates with the rotating ring 16, so that the dust and impurities circulate in the ring cover 17, and thus are more easily sucked away by the mini vacuum cleaner 61. The ventilation groove 7 on the inclined surface of the air guiding block 31 can further optimize the flow of the airflow, making the airflow pass more smoothly around the air guiding block 31, improving the ventilation efficiency, and thus enhancing the heat dissipation effect of the entire heat dissipation system.;
