Abstract
Description
Technical Field
[0001] This utility model relates to the field of shielding door technology, specifically a protective and airtight shielding door. Background Technology
[0002] Shielding doors are critical protective equipment in substations, specifically designed for the electromagnetic environment and safety protection needs of power scenarios. They are primarily used in core areas such as relay rooms, high-voltage test areas, and main control rooms. Based on a special structure and shielding materials, they effectively block external electromagnetic interference, ensuring the stable operation of precision electronic equipment and communication systems within the substation. They also suppress the outward diffusion of electromagnetic radiation from equipment within the substation, preventing interference with the normal operation of surrounding equipment and harm to personnel health. Furthermore, they possess information security protection functions, preventing the leakage of electronic communication information through electromagnetic radiation. Products are available in various types based on opening method, including manual swing-out, electric swing-out, and sliding types. Materials include carbon steel, stainless steel, and copper. Some models also integrate fireproofing and sound insulation functions, adapting to different protection levels and usage requirements in various substation scenarios. They are essential facilities for ensuring the stability, safety, and information confidentiality of substation operations.
[0003] Patent publication number "CN218716392U" discloses a protective airtight shielding door, relating to the field of underground engineering protection equipment technology. It addresses the problem that some existing protective airtight shielding doors require manual operation to close the ventilation openings, which is time-consuming and laborious, and remote closure is not possible. The new door includes a protective door body and a ventilation opening on the door body. A fixing block is fixedly installed inside the door body, and a bidirectional threaded rod is rotatably connected inside the fixing block. One end of the bidirectional threaded rod is rotatably connected to the door body, and a drive mechanism is connected to the end of the bidirectional threaded rod near the fixing block. When the ventilation opening needs to be closed, the operator only needs to control the drive mechanism, which moves the threaded block. With the assistance of a support rod, the threaded block moves a lifting plate upwards, thus quickly closing the ventilation opening.
[0004] The aforementioned patents indicate that existing shielding doors lack effective anti-slip features, causing their handles to slip during use, which affects their opening and closing performance. Furthermore, they lack adequate cleaning capabilities under the door, leaving dust residue that negatively impacts the user experience.
[0005] Therefore, this utility model provides a protective and airtight shielding door to solve the above problems. Utility Model Content
[0006] In view of the shortcomings of the existing technology, this utility model provides a protective and airtight shielding door, which solves the problem that the existing shielding doors do not have a good anti-slip function and the handles are prone to slipping during use, which affects the opening and closing effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective airtight shielding door, comprising a door frame, a shielding door body connected to one side of the door frame via a hinge, an anti-slip component fixedly installed on one side of the shielding door body, and a cleaning component fixedly installed on one side of the shielding door body; the anti-slip component comprises a handle and positioning blocks, the handle being fixedly installed on one side of the shielding door body, the positioning blocks being fixedly installed on both sides of the handle, an anti-slip shell one and an anti-slip shell two being respectively engaged on both sides of the handle, the anti-slip shell one and the anti-slip shell two being engaged with the positioning blocks respectively, and a screw being connected to one side of the anti-slip shell one, the screw being connected to the handle and the anti-slip shell two respectively via threads.
[0008] Furthermore, the anti-slip component also includes a nut, which is threaded onto the sidewall of the screw.

[0010] Furthermore, the cleaning assembly includes an L-shaped frame and a brush, with the L-shaped frame disposed on one side of the shielding door and the brush disposed at the bottom of the L-shaped frame.
[0011] The above technical solution automatically cleans the bottom dust without manual intervention, ensuring smooth door operation.
[0012] Furthermore, the cleaning assembly also includes a positioning rod, which is fixedly installed on one side of the shielding door, and the L-shaped frame is engaged with the positioning rod.
[0013] The above technical solution facilitates the assembly and disassembly of the L-shaped frame, which is beneficial for brush maintenance and improves operational flexibility.
[0014] Furthermore, the cleaning assembly also includes a first connecting frame and a second connecting frame. The first connecting frame is fixedly installed on one side of the door frame, and the second connecting frame is fixedly installed on the top of the L-shaped frame. The second connecting frame and the first connecting frame are interlocked.
[0015] By adopting the above technical solution, the L-shaped frame is securely installed, avoiding displacement and ensuring accurate cleaning trajectory.
[0016] Furthermore, the cleaning assembly also includes a threaded rod and a knob. The threaded rod is threadedly connected to the top of the first connecting frame, and the threaded rod is threadedly connected to the second connecting frame. The knob is fixedly connected to the top of the threaded rod.
[0017] By adopting the above technical solution, the brush height can be adjusted to suit different scenarios and improve the thoroughness of cleaning.
[0018] Furthermore, the cleaning component also includes locking blocks, which are fixedly installed on both sides of the second connecting frame and are engaged with the first connecting frame.
[0019] The above technical solution uses bidirectional limiting and fixing to prevent displacement and ensure the stability and durability of the components.
[0020] Beneficial effects
[0021] This utility model provides a protective, airtight shielding door. Compared with the prior art, it has the following advantages:
[0022] 1. This protective airtight shielded door features anti-slip components that prevent the handle from slipping, making it more comfortable to use. This allows operators to maintain a firm grip even in wet environments or when wearing protective gloves, preventing operational errors or hand fatigue caused by slipping. It also effectively reduces the risk of equipment collisions caused by unstable grips during door opening and closing, further enhancing the safety and convenience of the door.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0032] Reference Figures 1 to 4 This application provides a protective airtight shielding door, including a door frame 1. A shielding door body 2 is connected to one side of the door frame 1 via a hinge. An anti-slip component 3 is fixedly installed on one side of the shielding door body 2, and a cleaning component 4 is fixedly installed on one side of the shielding door body 2. The anti-slip component 3 includes a handle 31 and a positioning block 32. The handle 31 is fixedly installed on one side of the shielding door body 2, and the positioning blocks 32 are respectively fixedly installed on both sides of the handle 31. Anti-slip shell 1 33 and anti-slip shell 2 34 are respectively snapped onto both sides of the handle 31. Anti-slip shell 2 34 and anti-slip shell 1 33 are respectively snapped onto the positioning block 32. A screw 35 is connected to one side of the anti-slip shell 1 33. The screw 35 is respectively connected to the handle 31 and anti-slip shell 2 34 via threads. The anti-slip component 3 also includes a nut 36, which is threaded onto the side wall of the screw 35.
[0033] In this embodiment, the handle 31 is fixed to one side of the shielding door body 2. The positioning blocks 32 on both sides provide a precise installation reference for the anti-slip shell 33 and the anti-slip shell 34. The snap-fit structure enables quick positioning and fitting, ensuring the assembly stability of the anti-slip components and the handle 31. During assembly, the screws 35 pass through the anti-slip shell 33 and the handle 31 in sequence and are threadedly connected to the anti-slip shell 34 to form a three-point fixing structure, so that the anti-slip shell tightly wraps the surface of the handle 31. The material properties and surface texture of the anti-slip shell enhance the grip friction. At the same time, the positioning blocks 32 restrict the lateral displacement of the anti-slip shell to avoid loosening or displacement during use, ensuring grip stability and comfort during operation.
[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the cleaning component 4 includes an L-shaped frame 41 and a brush 42. The L-shaped frame 41 is disposed on one side of the shielding door 2, and the brush 42 is disposed at the bottom of the L-shaped frame 41. The cleaning component 4 also includes a positioning rod 43, which is fixedly installed on one side of the shielding door 2. The L-shaped frame 41 and the positioning rod 43 are engaged with each other. The cleaning component 4 also includes a first connecting frame 44 and a second connecting frame 45. The first connecting frame 44 is fixedly installed on one side of the door frame 1, and the second connecting frame 45 is fixedly installed on the top of the L-shaped frame 41. The second connecting frame 45 and the first connecting frame 44 are engaged with each other. The cleaning component 4 also includes a threaded rod 46 and a knob 47. The threaded rod 46 is threadedly connected to the top of the first connecting frame 44, and the threaded rod 46 and the second connecting frame 45 are threadedly connected. The knob 47 is fixedly connected to the top of the threaded rod 46. The cleaning component 4 also includes a locking block 48, which is fixedly installed on both sides of the second connecting frame 45 and is engaged with the first connecting frame 44.
[0035] In this embodiment, the L-shaped frame 41 is fixed to the shielding door body 2 by the positioning rod 43. The bottom brush 42 is kept in contact with the ground. When the door is opened and closed, the brush 42 moves synchronously with the door to clean the bottom track and contact surface in real time, effectively removing dust and debris. The snap-fit structure of the connecting frame 1 44 and the connecting frame 2 45 enhances the installation stability of the L-shaped frame 41. The two side blocks 48 realize bidirectional limiting to prevent lateral displacement. The rotating knob 47 can adjust the height of the connecting frame 2 45 through the threaded rod 46, thereby adjusting the contact degree between the brush 42 and the ground to adapt to different cleaning scenarios. In addition, the nut 36 locks the screw 35 with a thread to prevent the anti-slip component from loosening after long-term use, ensuring the anti-slip effect is continuously stable. The overall structure achieves the unity of convenient operation, automated cleaning and installation stability through the cooperation of components, ensuring the long-term reliable operation of the shielding door. In this case, the thread helix angle is less than or equal to the equivalent friction angle.
[0036] Working principle: The handle 31 is fixed to one side of the shielding door body 2. The positioning blocks 32 on both sides provide a precise installation reference for the anti-slip shell 1 33 and anti-slip shell 2 34. The snap-fit structure realizes quick positioning and fitting, ensuring the assembly stability of the anti-slip parts and the handle 31. During assembly, the screw 35 passes through the anti-slip shell 1 33 and the handle 31 in sequence and is threadedly connected to the anti-slip shell 2 34 to form a three-point fixing structure, so that the anti-slip shell tightly wraps the surface of the handle 31. The material characteristics and surface texture of the anti-slip shell enhance the grip friction. At the same time, the positioning block 32 restricts the lateral displacement of the anti-slip shell to avoid loosening or displacement during use, ensuring the grip stability and comfort during operation.
[0037] L-shaped frame 41 is fixed to the shielding door body 2 by positioning rod 43. The bottom brush 42 keeps in contact with the ground. When the door is opened and closed, the brush 42 moves synchronously with the door to clean the bottom track and contact surface in real time, effectively removing dust and debris. The snap-fit structure of connecting frame one 44 and connecting frame two 45 enhances the installation stability of L-shaped frame 41. The two side locking blocks 48 realize bidirectional limiting to prevent lateral displacement. Rotating knob 47 can adjust the height of connecting frame two 45 through threaded rod 46, thereby adjusting the contact degree between brush 42 and the ground to adapt to different cleaning scenarios. In addition, nut 36 locks the screw 35 with thread to prevent the anti-slip components from loosening after long-term use, ensuring the anti-slip effect is continuously stable. The overall structure achieves the unity of convenient operation, automated cleaning and installation stability through component collaboration, ensuring the long-term reliable operation of the shielding door.
