Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-3 The utility model provides a technical solution: a shielding cover that can be disassembled as a whole, comprising: a fireproof and high-temperature resistant layer 1, the fireproof and high-temperature resistant layer 1 is used to withstand the burning of high-temperature environment and electric arc; an electromagnetic shielding layer 2, the electromagnetic shielding layer 2 is compounded on the side wall surface of the fireproof and high-temperature resistant layer 1, and the electromagnetic shielding layer 2 is used to absorb and shield electromagnetic radiation; a lifting component 3, the lifting component 3 is arranged on one side of the electromagnetic shielding layer 2, and the lifting component 3 is used to lift the electromagnetic shielding layer 2; and a restraining component 4, a plurality of restraining components 4 are provided, and a plurality of restraining components 4 are ring-arranged on the side wall surface of the electromagnetic shielding layer 2, and the restraining component 4 is detachably connected to the lifting component 3;

[0031] Through the supporting component 3, it can be installed in the designated position and provide an attachment basis for the electromagnetic shielding layer 2. Since one side wall of the electromagnetic shielding layer 2 is compounded with the fireproof and high-temperature resistant layer 1, and the other side is provided with multiple restraining components 4, when it is necessary to install the electromagnetic shielding layer 2 and the fireproof and high-temperature resistant layer 1, at this time, the staff only needs to cover the multiple restraining components 4 on the supporting component 3, so as to achieve the purpose of limiting the installation of the fireproof and high-temperature resistant layer 1 and the electromagnetic shielding layer 2. When it is necessary to replace the fireproof and high-temperature resistant layer 1 and the electromagnetic shielding layer 2, at this time, only the restraining component 4 needs to be removed, and the entire fireproof and high-temperature resistant layer 1 and the electromagnetic shielding layer 2 can be quickly disassembled and disassembled, which improves the convenience of replacement of the two and reduces the maintenance cost. Through the fireproof and high-temperature resistant layer 1, it can withstand high temperature environment and arc burning, thereby ensuring that the arc will not cause fire and further spread to the outside world, and then through the electromagnetic shielding layer 2, it can absorb and shield electromagnetic radiation, thereby reducing the impact on the human body and equipment.

[0032] See also Figure 3 , Figure 4 The fireproof and high temperature resistant layer 1 comprises a first flame retardant Oxford cloth layer 11, a ceramic fiber felt layer 12 is compounded on one side wall surface of the first flame retardant Oxford cloth layer 11, a nano aerogel felt layer 13 is compounded on one side wall surface of the ceramic fiber felt layer 12, and the surfaces of the first flame retardant Oxford cloth layer 11, the ceramic fiber felt layer 12 and the nano aerogel felt layer 13 are all sprayed with a flame retardant 14;

[0033] The first flame retardant Oxford cloth layer 11 in the fireproof and high temperature proof layer 1 can not only achieve the purpose of preliminary flame retardancy, but also protect the ceramic fiber felt layer 12 and the nano aerogel felt layer 13. Then, the ceramic fiber felt layer 12 and the nano aerogel felt layer 13 can withstand the high temperature environment and the burning of the electric arc, thereby ensuring that the electric arc will not cause a fire and further spread to the outside world. In addition, since the surfaces of the first flame retardant Oxford cloth layer 11, the ceramic fiber felt layer 12 and the nano aerogel felt layer 13 are all coated with a flame retardant 14, the fireproof performance of the fireproof and high temperature proof layer 1 is improved, and its safety in use is improved.

[0034] See also Figure 4 , Figure 5 The electromagnetic shielding layer 2 includes an electromagnetic shielding net 22 disposed on a side wall surface of the nano-aerogel felt layer 13, and an electromagnetic shielding film 21 is compounded on a side wall surface of the electromagnetic shielding net 22;

[0035] The electromagnetic shielding net 22 in the electromagnetic shielding layer 2 can be composited with the nano aerogel felt layer 13 and the electromagnetic shielding film 21. Then, the electromagnetic shielding film 21 and the electromagnetic shielding net 22 can achieve dual absorption and shielding of electromagnetic radiation, thereby reducing the impact on the human body and equipment.

[0036] See also Figure 3 , Figure 6 The lifting assembly 3 includes a support frame 31, a middle frame 32 is arranged in the middle of the inner cavity of the support frame 31, and a plurality of stabilizing rods 33 are arranged around the outer wall of the middle frame 32, and the top ends of the plurality of stabilizing rods 33 are respectively connected to the inner wall of the support frame 31; mounting parts are arranged on both sides of the surface of the middle frame 32, and the mounting parts are used to install and fix the middle frame 32, and the mounting parts include a support rod 34 arranged on one side of the surface of the middle frame 32, and a positioning plate 35 is fixedly arranged at one end of the support rod 34;

[0037] By lifting the middle frame 32 in the assembly 3, the support frame 31 can be installed through multiple stabilizing rods 33, and the corresponding positioning plate 35 can be installed through two support rods 34. At the same time, the middle frame 32 can provide a supporting basis for the fire and high temperature protection layer 1 and the electromagnetic shielding layer 2, so that the two can shield high-voltage arcs. Through the positioning plate 35, it can be fixed in a specified position, so that the middle frame 32 can be provided with stable support through the support rods 34, thereby improving the stability of the middle frame 32 and the support frame 31.

[0038] See also Figure 5 , Figure 7 The restraint component 4 includes a second flame-retardant Oxford cloth layer 41 disposed on one side surface of the electromagnetic shielding film 21, the second flame-retardant Oxford cloth layer 41 is sewn with a first strap 42 and a second strap 43 at the bottom and top, respectively, a sub-velcro 44 is sewn at one end of the top surface of the first strap 42, and a mother-velcro 45 is sewn at one end of the top surface of the second strap 43;

[0039] Through the second flame retardant Oxford cloth layer 41 in the binding component 4, it can be compounded on the electromagnetic shielding film 21, and the first strap 42 and the second strap 43 can be sewn. Since a sub-Velcro 44 is sewn on one end of the top surface of the first strap 42, and a mother Velcro 45 is sewn on one end of the top surface of the second strap 43, the sub-Velcro 44 and the mother Velcro 45 are bonded to each other, so that one end of the first strap 42 and the second strap 43 can be bonded together, and then the second flame retardant Oxford cloth layer 41 can be bound to the support frame 31, so that the fire and high temperature protection layer 1 and the electromagnetic shielding layer 2 can be stably supported. When the two need to be disassembled as a whole, at this time, just tear off the sub-Velcro 44 and the mother Velcro 45, and the first strap 42 and the second strap 43 can be quickly removed, so that the fire and high temperature protection layer 1 and the electromagnetic shielding layer 2 can be completely replaced and maintained.

[0040] During operation, the supporting component 3 can be installed at the designated position and provide an attachment basis for the electromagnetic shielding layer 2. Since one side wall of the electromagnetic shielding layer 2 is compounded with the fireproof and high-temperature resistant layer 1, and the other side is provided with multiple restraining components 4, when it is necessary to install the electromagnetic shielding layer 2 and the fireproof and high-temperature resistant layer 1, the staff only needs to cover the multiple restraining components 4 on the supporting component 3, so as to achieve the purpose of limiting the installation of the fireproof and high-temperature resistant layer 1 and the electromagnetic shielding layer 2. When it is necessary to replace the fireproof and high-temperature resistant layer 1 and the electromagnetic shielding layer 2, it is only necessary to remove the restraining component 4, and the entire fireproof and high-temperature resistant layer 1 and the electromagnetic shielding layer 2 can be quickly disassembled, which improves the convenience of replacement of the two and reduces the maintenance cost. Through the fireproof and high-temperature resistant layer 1, it can withstand high temperature environment and arc burning, thereby ensuring that the arc will not cause fire and further spread to the outside world. Then, through the electromagnetic shielding layer 2, it can absorb and shield electromagnetic radiation, thereby reducing the impact on the human body and equipment.

[0041] The first flame retardant Oxford cloth layer 11 in the fireproof and high temperature proof layer 1 can not only achieve the purpose of preliminary flame retardancy, but also protect the ceramic fiber felt layer 12 and the nano aerogel felt layer 13. Then, the ceramic fiber felt layer 12 and the nano aerogel felt layer 13 can withstand the high temperature environment and the burning of the electric arc, thereby ensuring that the electric arc will not cause a fire and further spread to the outside world. In addition, since the surfaces of the first flame retardant Oxford cloth layer 11, the ceramic fiber felt layer 12 and the nano aerogel felt layer 13 are all coated with a flame retardant 14, the fireproof performance of the fireproof and high temperature proof layer 1 is improved, and its safety in use is improved.

[0042] The electromagnetic shielding net 22 in the electromagnetic shielding layer 2 can be composited with the nano aerogel felt layer 13 and the electromagnetic shielding film 21. Then, the electromagnetic shielding film 21 and the electromagnetic shielding net 22 can achieve dual absorption and shielding of electromagnetic radiation, thereby reducing the impact on the human body and equipment.

[0043] By lifting the middle frame 32 in the assembly 3, the support frame 31 can be installed through multiple stabilizing rods 33, and the corresponding positioning plate 35 can be installed through two support rods 34. At the same time, the middle frame 32 can provide a supporting basis for the fire and high temperature protection layer 1 and the electromagnetic shielding layer 2, so that the two can shield high-voltage arcs. Through the positioning plate 35, it can be fixed in a specified position, so that the middle frame 32 can be provided with stable support through the support rods 34, thereby improving the stability of the middle frame 32 and the support frame 31.

[0044] Through the second flame retardant Oxford cloth layer 41 in the binding component 4, it can be compounded on the electromagnetic shielding film 21, and the first strap 42 and the second strap 43 can be sewn. Since a sub-Velcro 44 is sewn on one end of the top surface of the first strap 42, and a mother Velcro 45 is sewn on one end of the top surface of the second strap 43, the sub-Velcro 44 and the mother Velcro 45 are bonded to each other, so that one end of the first strap 42 and the second strap 43 can be bonded together, and then the second flame retardant Oxford cloth layer 41 can be bound to the support frame 31, so that the fire and high temperature protection layer 1 and the electromagnetic shielding layer 2 can be stably supported. When the two need to be disassembled as a whole, at this time, just tear off the sub-Velcro 44 and the mother Velcro 45, and the first strap 42 and the second strap 43 can be quickly removed, so that the fire and high temperature protection layer 1 and the electromagnetic shielding layer 2 can be completely replaced and maintained.

[0045] In summary, the device can not only shield high-voltage arcs, but also facilitate workers to quickly disassemble and replace it, thereby improving the convenience of equipment use and reducing its maintenance costs.
