Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, in particular to a network security protection device. Background Art

[0002] A switch is a common network device in computer networks, used to connect multiple computers and other network devices in a local area network (LAN). The main function of a switch is to forward network data packets from one port to another based on the MAC address of the target device to enable communication between devices. Switches play an important role in LANs, providing high-speed, reliable data transmission and enabling data segmentation, broadcasting, and multicasting. In component LANs, multiple switches are used, and switches are generally installed in cabinets. Traditional cabinets are equipped with heat dissipation devices, but they absorb a lot of dust during the heat dissipation process, causing dust to enter and affecting heat dissipation, thereby affecting the heat dissipation of the switch.

[0003] The patent with publication number CN221728447U discloses a network security protection device, including a cabinet, an exhaust device is provided on the top of the cabinet and a cabinet door is provided on the surface, a sliding rod is provided inside the cabinet and a placement plate is provided on the surface of the sliding rod, the placement plate and the sliding rod are slidably connected, a switch is provided on the surface of the placement plate, a junction box is provided on the back of the cabinet and the junction box and the switch are electrically connected. The utility model is provided with a junction box on the back of the cabinet and the junction box and the switch are electrically connected, a mounting frame is provided at the bottom of the junction box and a motor is provided on the side of the mounting frame, a drive shaft is provided at the power output end of the motor and a mounting roller is provided on the surface of the drive shaft, a filter is provided on the surface of the mounting roller and the filter is rotated by the mounting roller, and the cyclic rotation of the filter can achieve cyclic filtration. The double filtration method increases the filtration effect while avoiding clogging of the filter.

[0004] The above-mentioned prior art drives the driving shaft and the mounting roller to rotate through a motor, so that the filter rotates along with the mounting roller, and realizes circulating filtration through the cyclic rotation of the filter, while avoiding clogging of the filter. However, the filtering surface of the filter is located on the outer surface, and the filtered impurities will adhere to the surface of the filter. When the filtering surface of the filter rotates to the inside of the mounting frame, that is, the channel connected to the cabinet, under the action of the airflow, the impurities adhered to the surface of the filter will be blown into the cabinet, and it will not be able to prevent dust from entering the cabinet. Therefore, the above-mentioned prior art has technical defects. In view of this, we propose a network security protection device. Utility Model Content

The filter hole size of each layer of filter panels decreases successively, ensuring that dust of different particle sizes can be effectively blocked, thereby improving the overall dust prevention effect and extending the service life of the equipment.

[0019] 2. The network security protection device has a built-in fan system, combined with the intelligent control of the thermostat, which can effectively manage and adjust the temperature inside the cabinet. Once the temperature is detected to be too high, the system automatically turns on the second row of fans and the second auxiliary fan to accelerate the discharge of internal heat and prevent the equipment from performance degradation or damage due to overheating.

[0020] 3. The network security protection device, with its support bars and air holes on the support partition, creates good air flow conditions for the switch, promotes vertical air flow in the cabinet, and improves heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
