Description

Technical Field

[0001] The present invention relates to the technical field of network security, and in particular to a network security isolation device. Background Art

[0002] Network security isolation devices are typically used to create physical isolation in computer systems to prevent data from flowing from one network into another network usage environment, such as the military, government agencies, financial institutions, and other occasions that require strict data protection. As a common problem of electronic equipment, network security isolation devices will also generate a lot of heat under high-performance computing and long-term operation. If not handled in time, the failure rate of network security isolation devices will increase and affect their service life.

[0003] In recent years, with the rapid development of relevant technologies, some heat dissipation devices for network security isolation equipment have begun to be put into use. However, after actual use, the applicant found that the heat dissipation devices currently used are mostly air-cooled heat dissipation materials. In order to prevent dust in the environment from contacting the network security isolation equipment along with the cooling airflow, the existing technology mostly sets a filter at the air inlet. However, this protection method is effective in the initial use process, but as the use time increases, blockage problems will occur, which will reduce the air supply cooling effect and require frequent manual cleaning. The performance still needs to be further improved. Summary of the invention

[0038] Working principle:

[0039] Embodiment 1

[0040] During the use of the isolation device body 1, when the isolation device body 1 is subjected to vibration, the damping support rods 22 arranged at the bottom and top of the isolation device body 1 can cooperate with the outer protection box 2 and the support frame 3 to perform damping and buffering. When the temperature sensor 14 detects that the temperature of the space where the isolation device body 1 is located has risen, the servo motor 19 is started, and the output end of the servo motor 19 drives the first gear 20 to rotate synchronously, and then the first gear 20 is engaged with the second gear 21 to drive the second gear 21 to drive the transmission shaft 4 and the four blades 6 to rotate synchronously, and the four blades 6 are used to accelerate the air inside the transition wind box 5 and make the air inside the transition wind box 5 flow quickly to the transition sleeve 8. The horizontal filter screen 11 inside the transition sleeve 8 will filter the flowing air, and the filtered air then enters the interior of the frame box 211 through the guide pipe 9 to cool the isolation device body 1 by air.

[0041] When the filter screen 11 has been used for a certain period of time, the servo motor 19 can be temporarily turned off to suspend air supply. Then, the adjusting shaft 12 on the top of the adjusting circular plate 10 is turned to overcome the magnetic attraction of the magnet ring, so that the adjusting circular plate 10 is changed from a vertical state to a horizontal state, and the internal flow channel space of the transition sleeve 8 is temporarily closed, and then the valve inside the ash discharge valve pipe 13 is opened;

[0042] The adjusting shaft 12 on the top of the filter screen plate 11 is turned to overcome the magnetic attraction of the magnet ring and flip the filter screen plate 11 180 degrees, and the filter surface of the filter screen plate 11 is facing the adjusting circular plate 10, and the servo motor 19 is started, and the output end of the servo motor 19 drives the first gear 20 to rotate synchronously, and then the first gear 20 is meshed with the second gear 21, so that the second gear 21 drives the transmission shaft 4 and the four blades 6 to rotate synchronously, and the four blades 6 are used to accelerate the air inside the transition bellows 5, and then the fast-flowing air is used to impact the filter screen plate 11 to achieve a reverse flushing effect, and then the impurities on the filter surface of the filter screen plate 11 are discharged through the ash discharge valve pipe 13;

[0043] After the self-cleaning of the filter screen plate 11 is completed, the valves of the servo motor 19 and the ash discharge valve pipe 13 are closed, and the adjusting circular plate 10 and the filter screen plate 11 are reset, and the filter screen plate 11 can be continued to be used.

[0044] Embodiment 2

[0045] When the cooling speed of the isolation device body 1 does not reach the ideal level according to the operation of the first embodiment, the electric push rod 18 can be opened and closed reciprocatingly during the synchronous rotation output of the transmission shaft 4 and the fan blades 6, and the output end of the electric push rod 18 can reciprocately press the elastic balloon 161 inside the elastic pressure component 16, so that the elastic balloon 161 and the auxiliary spring sheet 163 are reciprocatedly deformed, and then the cooling fluid inside the coolant box 15 is sent to the liquid drainage tube 17 sleeved on the front end of the transmission shaft 4 by using the one-way drainage effect of the two one-way valve tubes 162, and then enters the transmission shaft 4 and the fan blades 6 of the hollow structure, and then the heat conduction principle is used to assist in cooling the air inside the transition wind box 5 without interfering with the rotation output of the transmission shaft 4 and the fan blades 6;

[0046] The used coolant will flow back to the interior of the coolant box 15 through the transmission shaft 4 and another liquid drainage pipe 17, and then reciprocate according to the above steps, using the superimposed effect of air cooling and liquid cooling to ensure the cooling and heat dissipation effect of the isolation equipment body 1.

[0047] Embodiment 3

[0048] When the isolation device body 1 needs maintenance, remove the screws between the frame box 211 and the sealing frame plate 212, and take out the isolation device body 1. When the internal associated structure of the support frame 3 fails and needs maintenance, remove the screws between the guide tube 9 and the frame box 211, and the screws between the frame box 211 and the support frame 3, so as to separate the outer protection box 2 and the support frame 3, providing convenient conditions for modular maintenance of the associated structure inside the support frame 3.
