Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cleanrooms, and in particular to a protective device for a cleanroom based on cable welding. Background Technology
[0002] As a crucial carrier for power transmission and signal transmission, the safe and stable operation of cables is of paramount importance. During long-term use, cables inevitably experience localized damage or breakage, necessitating welding repair. However, traditional cable welding environments present significant challenges: the welding process generates high-temperature molten metal spatter, toxic and harmful gases (such as ozone and nitrogen oxides), and metallic fumes.
[0003] To prevent these hazardous factors from spreading and polluting the environment and to protect the health of maintenance personnel, cleanrooms for cable welding (or welding isolation chambers) have become key equipment for on-site welding repair. They create a relatively enclosed, clean space around the welding point, effectively isolating or removing harmful substances.
[0004] However, existing cleanroom technologies for cable welding have several significant drawbacks in practical applications that urgently need improvement:
[0005] Cable securing and sealing are challenging: Cables under repair must penetrate the cleanroom walls to enter the internal operating space. Traditional cleanroom sealing methods at cable entry points (usually through openings in doors or covers) are often unreliable and cumbersome. Simple sealing rings or glands are ill-suited to varying cable diameters, easily creating gaps that allow welding fumes, harmful gases, and metal spatter to leak into the external environment, threatening the health and safety of operators (welders and surrounding personnel). Furthermore, existing cable clamping methods may be unstable, easily shifting during installation, affecting sealing effectiveness and operational safety.
[0006] Inconvenient access to protective equipment: Welding cleanroom maintenance personnel need to wear personal protective equipment (PPE) such as respirators and goggles. Existing cleanroom designs typically store this necessary PPE in toolboxes or cases separate from the work area. When maintenance personnel need to urgently or conveniently access this equipment after entering the cleanroom, they must interrupt operations and leave the sealed area to find it, significantly reducing work efficiency, especially in confined or emergency maintenance scenarios. This also poses a risk of airtightness loss due to operational interruption. Utility Model Content
[0007] This utility model aims to at least partially solve one of the technical problems in the related art.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the appended spirit and connotation.
[0025] The protective device for a cleanroom based on cable welding, according to an embodiment of the present invention, will be described below with reference to the accompanying drawings.
[0026] like Figure 1-5 As shown, the protective device for a cleanroom based on cable welding according to this utility model embodiment includes a cleanroom body 10, a flip cover 20, and a protective component 30.
[0027] The flip cover 20 is mounted on the cleanroom body 10 by a hinge. The flip cover 20 has a horizontal long flip cover and a vertical short flip cover. The short flip cover has a through groove. When repairing the cable, the cable is bound in the through groove and the flip cover 20 is closed.
[0028] The protective component 30 is installed inside the cleanroom body 10. The protective component 30 includes a positioning frame 301, a holding component 302, a fixed shaft 303, and a fastening and sealing mechanism 304.
[0029] The positioning frame 301 is installed inside the cleanroom body 10, the fixed shaft 303 is installed inside the cleanroom body 10, and the container 302 is rotatably mounted on the fixed shaft 303 and engaged with the positioning frame 301. There are two sets of fastening and sealing mechanisms 304, each movably mounted on the fixed shaft 303.
[0030] It should be noted that the positioning frame 301 is a plate frame perpendicular to the cleanroom body 10. The plate frame is provided with a protrusion. The fixed shaft 303 and the cleanroom body 10 are in a parallel state. There is a gap between the fixed shaft 303 and the inner wall of the cleanroom body. The holding part 302 and the fastening and sealing mechanism 304 are respectively movably arranged on the fixed shaft 303.
[0031] In one embodiment of this utility model, such as Figure 2 As shown, the fastening and sealing mechanism 304 includes a movable clamp 3041, a telescopic rod 3042, a base plate 3043, and a fastening and sealing element 3044.
[0032] The movable clamp 3041 is movably mounted on the fixed shaft 303, the fixed end of the telescopic rod 3042 is mounted on the movable clamp 3041, the base plate 3043 is mounted on the movable end of the telescopic rod 3042, and the fastening seal 3044 is mounted on the base plate 3043.
[0033] It should be noted that the movable locking piece 3041 moves and adjusts on the fixed shaft 303, and a positioning slot is provided on the holding part 302, so the movable locking piece 3041 is engaged in the positioning slot. The base plate 3043 is installed on the telescopic rod 3042, so the telescopic rod 3042 moves to push the base plate 3043 to adjust its height.
[0034] In one embodiment of this utility model, such as Figure 4 As shown, the movable card 3041 includes a movable ring 30411 and a locking lever 30412.
[0035] The movable ring 30411 is movably mounted on the fixed shaft 303, one end of the locking rod 30412 is mounted on the movable ring 30411, and the other end of the locking rod 30412 is engaged with the container 302.
[0036] It should be noted that the movable ring 30411 is sleeved on the fixed shaft 303, and the locking rod 30412 on the movable ring 30411 is engaged in the positioning slot when moving. Thus, when the cleanroom body 10 is moved, the movable locking piece 3041 is engaged and fixed on the holding piece 302.
[0037] In one embodiment of this utility model, such as Figure 3 As shown, the fastening seal 3044 includes a fixed clamping plate 30441, a positioning screw 30442, a movable clamping plate 30443, an adjusting nut 30444, and a sealing component 30445.
[0038] The fixed clamping plate 30441 is mounted on the base plate 3043. Multiple sets of positioning screws 30442 are mounted on the fixed clamping plate 30441. The movable clamping plate 30443 is fitted onto the multiple sets of positioning screws 30442. Adjusting nuts 30444 are threaded onto the positioning screws 30442. Sealing components 30445 are respectively mounted within the fixed clamping plate 30441 and the movable clamping plate 30443.
[0039] It should be noted that the movable clamping plate 30443 moves on the positioning screw 30442, and the movable clamping plate 30443 and the fixed clamping plate 30441 move relative to each other. The adjusting nut 30444, when threaded, abuts against the bottom wall of the movable clamping plate 30443, thereby bringing the fixed clamping plate 30441 and the movable clamping plate 30443 into contact with the through groove of the flip cover 20, thus sealing the through groove.
[0040] In one embodiment of this utility model, such as Figure 2 As shown, the container 302 includes a movable base plate 3021 and a container body 3022.
[0041] The movable base plate 3021 is rotatably mounted on the fixed shaft 303, and the container 3022 is mounted on the movable base plate 3021.
[0042] It should be noted that a locking plate is provided on the movable base plate 3021, which engages with the protrusion on the top wall of the positioning frame 301.
[0043] Specifically, the steps for using the protective device in the cable welding cleanroom are as follows: First, open the flip cover 20 and secure the portion of the cable to be repaired within the cleanroom body 10. Then, close the flip cover 20. Maintenance personnel enter the cleanroom 10, move the movable ring 30411 on the fixed shaft 303, adjust the height of the telescopic rod 3042, and remove the movable clamp 30443. The fixed clamp 30441 is then placed against the cable surface, blocking the gap in the through-slot on the flip cover 20. The movable clamp 30443 is moved on the positioning screw 30442, and the adjusting nut 30444 is rotated to engage with the movable clamp 30443, thus fixing the movable clamp 30443 and the fixed clamp 30441 onto the cable, securing the cable and filling any gaps. Then, open the storage box 3022 and remove the breathing mask and protective goggles stored inside, facilitating effective protection for the maintenance personnel.
[0044] In summary, the protective device for cleanrooms based on cable welding according to this utility model embodiment fixes the cable with a fastening seal and seals the gap to ensure the stability of the cable and the cleanliness of the cleanroom during the maintenance process, while also facilitating the use of tools and speeding up the construction efficiency.
[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
