Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of campus network, especially relates to a kind of embedded campus network flow sampling device. BACKGROUND

[0002] As the core infrastructure bearing key businesses such as teaching, scientific research and management, the stable and efficient operation of campus network is crucial. Through collecting and analyzing network data packets, flow sampling devices can provide network administrators with critical insights for performance monitoring, troubleshooting, security auditing and bandwidth resource optimization. To save space and facilitate centralized management, such devices are typically designed as "embedded", i.e. compactly installed in standard server cabinets or converged switching cabinets. Due to the need for high-speed data processing, the electronic components inside these devices generate a large amount of heat continuously, so a reliable cooling system is necessary to ensure their long-term stable operation.

[0003] Currently, the mainstream embedded network devices on the market generally use forced air cooling design for cooling. Specifically, the internal structure usually has a cooling fan installed at one or more key positions. When the fan operates, cold air is drawn from the outside of the device, flows over the surfaces of heat-generating components such as the motherboard and processor, carries away the heat, and is finally discharged through the air outlet. To prevent dust, lint and other impurities in the external environment from being sucked into the device interior, which could cover the electronic components and affect the cooling efficiency or even cause short circuit risk, such devices usually install a dustproof filter screen at the air inlet of the fan. This filter screen is usually fixed in a frame and then fastened or clamped on a detachable panel or case cover through screws.

[0004] However, the above-mentioned traditional dustproof filter screen installation method has significant inconvenience in actual maintenance. The core problem is that to clean or replace the dust-filled filter screen, maintenance personnel must first use tools (such as screwdrivers) to disassemble part of the device front panel or entire housing. Considering that these embedded devices are usually densely deployed in narrow and crowded cabinet spaces, disassembly itself is very difficult, sometimes even requiring the device to be partially or completely removed from the cabinet, which not only consumes time and effort, but also risks accidental touch or unplugging of adjacent device cables. This cumbersome and potentially risky maintenance process makes routine cleaning of the filter screen easily neglected, and once the filter screen is severely clogged due to dust accumulation, it will directly lead to a sharp decline in device cooling efficiency, an increase in internal temperature, and ultimately may cause device performance instability, reduced operation speed, and even hardware overheating damage, etc. Therefore, an embedded campus network flow sampling device is proposed to solve the above problems. SUMMARY

During the whole process, the existence of the limiting wheel one and the limiting wheel two ensures the smoothness of the pushing and pulling. The use of screws and other fasteners is not needed, which simplifies the installation steps, shortens the deployment time, and can automatically adapt to the size tolerance within a certain range, and ensures the installation reliability of the equipment under various working conditions.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0034] With reference to Figure 1 - Figure 6 An embodiment provided by the present application is a kind of embedded campus network flow sampling device, including the shell 1 as the overall framework of equipment and protect internal components, the upper surface of shell 1 is provided with top cover 2 for closing shell 1 and as the operation interface, the inside of shell 1 is provided with electronic component board 3 for executing core data sampling and processing function, the inner wall of shell 1 is fixedly connected with fan 4 for forced air cooling heat dissipation, the inner wall of shell 1 is installed with filter assembly for purifying entering air;

[0035] The filtering assembly comprises a U-shaped shell 5 which plays a guiding and accommodating role, the lower surface of the U-shaped shell 5 is fixedly connected to the inner wall of the shell 1, the lower surface of the top cover 2 is fixedly connected with a telescopic rod 6 which realizes the ejection action, the lower end of the telescopic rod 6 is fixedly connected with a connecting block 8 which is used to transmit force, the outer wall of the telescopic rod 6 is sleeved with a spring 7 which provides the ejection elastic force, the outer wall of the connecting block 8 is fixedly connected with a connecting frame 9 which is used to bear the filtering plate 11, the inner wall of the connecting frame 9 is clamped with an extension block 10 which is used to extend and fix, the outer wall of the extension block 10 is fixedly connected with the filtering plate 11 which is the filtering main body, the filtering plate 11 is arranged at the air inlet close to the fan 4, the outer wall of the top cover 2 is rotatably connected with a rotating plate 12 which is the locking and releasing switch, the upper surface of the rotating plate 12 is fixedly connected with a buckle 13 which is used to cooperate with the latch 14, the upper surface of the top cover 2 is provided with the latch 14 which is used to lock the rotating plate 12 at the side close to the buckle 13; in order to ensure the movement track when it is ejected, the outer wall of the filtering plate 11 is slidably connected in the inside of the top cover 2, the lower surface of the rotating plate 12 abuts against the upper surface of the filtering plate 11, so as to limit the ejection in the locked state.

[0036] Specifically, in the locked state, the rotating plate 12 is fixed by the latch 14 and the buckle 13, the lower surface thereof presses the filtering plate 11 downward, and the spring 7 is compressed. When maintenance is needed, the operator pulls out the latch 14 and rotates the rotating plate 12, so that the filtering plate 11 is no longer pressed, the spring 7 is released, the whole filtering plate 11 assembly is ejected upward through the telescopic rod 6, and part of the filtering plate 11 is extended out of the top cover 2, so that the operator can directly take it out by hand for cleaning or replacement.

[0037] Referring to Figure 1 Figure 6 The outer wall of the shell 1 is fixedly connected with left-right symmetrical slide rails 15 which are used to guide the device to be embedded and installed, the inner side of the slide rail 15 is fixedly connected with a plurality of fixing boxes 16 which are used to accommodate fixing mechanisms; the inside of the fixing box 16 is slidably connected with a sliding rod 17 which is a movable base, the outer wall of the sliding rod 17 is rotatably connected with left-right symmetrical connecting plates 19 which are used to abut against the installation space; the inside of the two connecting plates 19 is fixedly connected with connecting shafts 18 which are used to provide pivot points, and the spring 21 which is used to provide outward opening elastic force is arranged between the two connecting shafts 18; in order to reduce the frictional force in the movement process, the outer wall of the two connecting shafts 18 is rotatably connected with limit wheels 20, and the outer wall of the two limit wheels 20 rolls in the inner wall of the fixing box 16; the outer wall of the sliding block 22 which is used to install auxiliary wheel sets is fixedly connected to the outer wall of the sliding rod 17, and the outer wall of the sliding block 22 is fixedly connected with left-right symmetrical connecting shafts 23; the outer wall of the connecting shaft 23 is rotatably connected with limit wheels 24 which play an auxiliary sliding role, and the outer wall of the limit wheel 24 is rotatably connected to one side of the sliding block 22.

[0038] ​Specifically, when the entire device is pushed into a mounting space such as a cabinet, the connecting plates 19 on both sides first contact the inner wall of the mounting space, and under the action of an external force, the connecting plates 19 will shrink inwardly and pivot against the elastic force of the second springs 21. In this process, the rolling action of the limiting wheels 20 and 24 ensures that the entire device can be smoothly and smoothly pushed in. When the device is completely in the predetermined position, the external pressure applied to the connecting plates 19 disappears, and the elastic potential energy stored by the second springs 21 is immediately released, pushing the two connecting plates 19 to open outwardly, so that they are tightly abutted against the inner wall of the mounting space, and the entire device is firmly and self-locked fixed by the generated friction and support force.

[0039] Working principle: when the device needs to be used, first, when installing and deploying, the staff holds the shell 1 and pushes it into the predetermined mounting space such as a cabinet, a wall recess, etc. During the pushing process, the fixed box 16 fixed on the slide rail 15 first enters the space, and the two connecting plates 19 inside it will shrink inwardly against the elastic force of the second springs 21 when they contact the inner wall of the mounting space. Thanks to the rolling action of the limiting wheels 20 and 24, the entire device can be smoothly pushed into the specified position. When the device is completely in place, the extrusion force applied to the connecting plates 19 disappears, and the second springs 21 immediately rebound, pushing the two connecting plates 19 to open outwardly, so that they are tightly abutted against the inner wall of the mounting space, and the entire device is firmly and stably fixed by the friction and support force, completing the tool-free quick installation;

[0040] Secondly, during daily operation, the electronic component board 3 inside generates heat, and the temperature control system starts the fan 4. When the fan 4 is running, the external cold air is sucked from the air inlet. Before entering the inside of the shell 1, the airflow must first pass through the filter plate 11 in the filter assembly. The filter plate 11 can effectively intercept dust and other impurities in the air, ensuring that the air entering the inside of the equipment is clean, thereby protecting the electronic component board 3 and other sensitive components from pollution and ensuring a good heat dissipation environment and long-term operation reliability.

[0041] Finally, when the filter plate 11 needs to be cleaned and maintained due to excessive dust accumulation after a long period of use, the convenient maintenance design of the utility model begins to play a role. The maintenance personnel first pull out the bolt 14 to release the locking of the rotating plate 12, and then rotate the rotating plate 12 by an angle. This rotation makes the lower surface of the rotating plate 12 no longer resist and limit the filter plate 11. At this time, the elastic potential energy stored by the compressed spring 7 is instantly released, pushing the telescopic rod 6 and the connecting block 8, the connecting frame 9 and the filter plate 11 connected thereto to pop up upwardly as a whole. The filter plate 11 partially protrudes from the top cover 2, and the operator can directly pull it out by hand for cleaning or replacement. After maintenance is completed, only the clean filter plate 11 is put back to the original position, the rotating plate 12 is pressed down and locked with the bolt 14 again, and the maintenance can be quickly completed, so that the equipment returns to normal work.

[0042] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
