[0002] Under the strong electromagnetic environment conditions such as in high-voltage substations with 220KV, in order to ensure the normal operation of the optoelectronic detection equipment of the operation robot, it is necessary to build a protection chamber for the optoelectronic detection equipment to suppress the magnetoelectric effect problem and the induced voltage discharge problem caused by the external strong electromagnetic field, and improve the stability of the optoelectronic detection equipment.

[0003] The shielding design of optoelectronic detection equipment for a 220KV strong electromagnetic environment is generally based on the Faraday cage electromagnetic shielding design, and its principle is to use a closed cage made of metal or good conductor.

[0004] In practical applications, under strong electromagnetic environment conditions, when the protection chamber cuts through a high electromagnetic field, an induced voltage will be generated, causing the voltage difference between different metal parts to produce end discharge, which is highly harmful to the optoelectronic detection equipment and other operation equipment. Summary of the Invention

[0019] Further, the electromagnetic shielding seal is a conductive sealing ring.

[0020] Further, the structure formed by connecting the front shielding cover and the rear shielding cover is streamlined.

[0021] Further, it further includes: a shielding rubber tube;

[0022] The shielding rubber tube is disposed at the rear end of the rear shielding cover and is used for sleeving a camera cable.

[0023] Further, the outer peripheries of the front shielding cover and the rear shielding cover are connected by a plurality of bolts.

[0043] See also Figures 1 to 3 In the first aspect of the embodiments of the present application, a strong electromagnetic protection cabin for high-altitude equipment is provided, including: a shielding light window 10, a shielding front cover 20 and a shielding rear cover 30; the shielding light window 10 is threadedly connected to the front end of the shielding front cover 20; the rear end of the shielding front cover 20 is connected to the front end of the shielding rear cover 30; an electromagnetic shielding seal 40 is arranged on the connection gap between the shielding front cover 20 and the shielding rear cover 30.

[0044] In existing protective warehouses, the light window structure is often connected to the warehouse body by welding, flange connection, etc., which may cause the problem of cumbersome assembly process and difficult disassembly. In this embodiment, the threaded connection method is used to facilitate the assembly and disassembly of the shielding light window 10, and at the same time, it helps to make the overall structure of the protective warehouse lighter and smaller.

[0045] In this embodiment, the electromagnetic shielding seal 40 located between the shielding front cover 20 and the shielding rear cover 30 can seal the gap between the two while also having an active discharge function to reduce the impact of the voltage difference on the photoelectric sensing instrument in a high electromagnetic environment, thereby meeting the stability requirements of the photoelectric detection equipment.

[0046] In a more specific embodiment, the shielding optical window 10 includes: a shielding glass 12, a shielding metal wire mesh 13, a sealing ring 14, and a rear seat 15; the rear end of the rear seat 15 is threadedly connected to the front end of the shielding front cover 20; the sealing ring 14 is disposed on the inner circumference of the rear seat 15; the shielding metal wire mesh 13 is disposed within the rear seat 15; the shielding glass 12 is sleeved within the sealing ring 14.

[0047] In this embodiment, the rear seat 15 serves as a support structure for installing the shielding glass 12, the shielding metal wire mesh 13, and the sealing ring 14. And, as Figure 3 shown, sealing rings 14 may be provided at both the front end and the rear end of the shielding glass 12 to improve its sealing effect; specifically, the shielding glass 12 may be nested within two sealing rings 14.

[0048] In a more specific embodiment, the shielding optical window 10 includes: a front seat 11 and a connecting screw; the front seat 11 is disposed at the front end of the rear seat 15; the connecting screw sequentially passes through the front seat 11, the rear seat 15, and the shielding front cover 20 to connect the front seat 11, the rear seat 15, and the shielding front cover 20.

[0049] In this embodiment, the front seat 11 is located at the front end of the shielding glass 12 and is used to protect the shielding glass 12. Among them, threaded hole structures may be provided on both the front seat 11 and the rear seat 15. The screw can pass through the threaded hole of the front seat 11, pass through the threaded hole on the rear seat 15, and finally be threadedly connected to the shielding front cover 20.

The rear seat 15 can be threadedly connected to the shielding front cover 20 through its external thread structure and the internal thread structure of the shielding front cover 20.

[0051] Steps are provided within the rear seat 15 such that the shielding metal wire mesh 13 can be snapped into the steps and abutted against a sealing ring 14. Specifically, after the shielding metal wire mesh 13 is inserted into the steps of the rear seat 15, the front end abuts against a sealing ring 14, and the rear end abuts against the shielding front cover 20, so that the shielding metal wire mesh 13 is fixed.

[0052] In a further improved embodiment, the sealing ring 14 is disposed between the front seat 11 and the rear seat 15, and the sealing ring 14 is a conductive sealing ring.

[0053] Specifically, in the case where two sealing rings 14 are provided, one sealing ring 14 can be disposed in the gap between the front seat 11 and the rear seat 15, or both sealing rings 14 can be disposed in the gap between the front seat 11 and the rear seat 15; in the latter case, the shielding glass 12 is only located within one sealing ring 14, and this sealing ring 14 is partially embedded in the front end of the rear seat 15, while the other sealing ring 14 is partially embedded in the rear end of the front seat 11; after the front seat 11 and the rear seat 15 are tightened by screws, the two sealing rings 14 are pressed and fixed between the front seat 11 and the rear seat 15, sealing the gap between the front seat 11 and the rear seat 15.

[0068] Further, threadedly connecting the shielding optical window 10 to the front end of the front shielding cover 20 includes:

[0069] Threadedly connect the rear end of the rear seat 15 to the front end of the front shielding cover 20;
