[0022] Secondly, the "one embodiment" or "embodiment" referred to here means that the specific features, structures or characteristics can be included in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or selective embodiment that excludes other embodiments. Embodiment

[0023] With reference to Figs. 1-4 For the embodiment of the utility model, the embodiment provides a substation shielding device for reducing electromagnetic interference, comprising,

[0024] The bearing mechanism 100 comprises a fixing piece 101;

[0025] The protection mechanism 200 comprises a shielding assembly 201 arranged on the top of the fixing piece 101 and a connecting assembly 202 arranged on the surface of the fixing piece 101.

[0026] Specifically, the fixing piece 101 comprises a fixed plate 1011 and an insert 1012 fixedly installed on the surface of the fixed plate 1011.

[0027] It should be noted that the fixed plate 1011 is made of high-strength metal material as the basic component of the bearing structure, which ensures the stability and durability of the whole bearing mechanism. The insert 1012 is a replaceable component designed according to the specific application requirements, which is precisely manufactured to realize seamless docking and firm installation with the surface of the fixed plate 1011. The insert 1012 not only can enhance the functional diversity of the fixing piece 101, but also can be quickly adjusted or replaced according to the different actual application scenes, greatly improving the adaptability and flexibility of the whole device. In addition, the design of the insert 1012 takes into account the needs of easy maintenance and upgrading, so that users can more conveniently maintain and functionally extend the equipment in the long-term use process.

[0028] Specifically, the shielding assembly 201 comprises a shielding device 2011 arranged on the surface of the fixed plate 1011 and a shielding ring 2012 arranged on one side of the shielding device 2011.

[0029] It should be noted that the shielding device 2011 is made of high-efficiency alloy material, aiming to maximize the protection effect of electromagnetic interference. The shielding ring 2012 is specially designed to closely cooperate with the shielding device, ensuring to provide all-round protection for the key electronic components and preventing external electromagnetic field from interfering with the normal operation of the equipment.

[0030] Specifically, the connecting assembly 202 comprises a dustproof shell 2021 arranged on the surface of the fixed plate 1011 and a power socket 2022 arranged at the bottom of the fixed plate 1011.

[0031] It should be noted that the dustproof shell 2021 not only can effectively prevent dust from entering the interior of the equipment, but also has certain heat dissipation function to ensure that the equipment can work stably in harsh environment. The power socket 2022 is specially designed to increase the waterproof and anti-electric shock protection measures, improving the safety of user's use.

[0032] Specifically, the protection mechanism 200 also includes a non-slip mat 203 arranged at the bottom of the fixed plate 1011, and an insulating mat 204 arranged at the bottom of the fixed plate 1011.

[0033] It should be noted that the non-slip mat 203 is made of high-friction material, which can ensure the stability of the device and prevent sliding caused by accidental collision or uneven surface. The insulating mat 204 is made of high-quality insulating material, which aims to enhance the electrical insulation performance of the bottom of the device and reduce the risk of current leakage, thereby ensuring the safety of the user.

[0034] In use, when using the device, first, according to the actual demand, the fixing part 101 is stably installed in the designated position, ensuring that the fixed plate 1011 is horizontal and firm. Then, the required plug-in part 1012 is fixed and installed on the surface of the fixed plate 1011 according to the design specifications to meet the specific functional requirements. Then, the protection mechanism 200 is set, including installing the shielding assembly 201 on the top of the fixing part 101, wherein the shielding device 2011 and the shielding ring 2012 work together to provide effective electromagnetic interference protection for the device. At the same time, the connecting assembly 202 is installed on the surface of the fixed plate 1011, which protects the internal electronic components from dust by the dustproof shell 2021, and uses the power socket 2022 at the bottom for safe power supply. In addition, in order to increase stability and safety, the non-slip mat 203 and the insulating mat 204 are arranged at the bottom of the fixed plate 1011 to prevent the device from sliding and reduce the risk of current leakage. The whole process needs to check whether each part is correctly installed, stable and reliable, to ensure that the device can run stably for a long time and exert the best performance.

[0035] In summary, through the cooperation of the components of the protection mechanism 200, not only the overall protection performance of the device is enhanced, but also the safety and stability of the power supply are ensured, which prolongs the service life of the device and improves its work efficiency.
