Description

Technical Field

[0001] This utility model relates to the field of dustproof shed technology, and in particular to an inflatable dustproof shed. Background Technology

[0002] Since the cleanliness of the interior of gas-insulated equipment directly affects its insulation performance and operational safety and reliability, the installation environment requirements for high-voltage gas-insulated switchgear (GIS) equipment and gas-insulated enclosed transmission line (GIL) equipment are very high. A cleanliness level of GMP-300,000 (equivalent to the manufacturer's cleanroom) must be achieved to strictly guarantee the quality of on-site installation.

[0003] Currently, GIS and GIL equipment are mostly simply enclosed with tarpaulins or plastic sheets as a dust prevention measure at actual installation sites. This cannot truly solve the problems of dust, insects, floating debris, and the environmental temperature, humidity, and moisture requirements of GIS and GIL equipment installation. The metal frame structure, composed of a metal frame and tarpaulin, is subject to thermal expansion and contraction at low or high ambient temperatures, causing the metal frame to deform and making installation difficult. Metal dustproof sheds are also bulky, take a long time to set up, and are inconvenient to transport. Furthermore, the metal frame is prone to poor sealing in areas with complex and uneven ground, leading to floating dust inside the shed and affecting the maintenance of GIS equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an inflatable dust-free shed, which solves the dust prevention problem of the on-site installation environment of GIS and GIL equipment.

[0005] The technical solution of this utility model is as follows: an inflatable dust-free shed includes a protective membrane, a protective cavity is provided inside the protective membrane, an observation window and an inflation port are provided on the protective membrane, and installation tube bags are integrally formed on both sides of the protective membrane. A double-layer composite bag mouth is provided at the opening edge of the installation tube bag, and a rope hole is provided in the double-layer composite bag mouth. A locking rope is threaded through the rope hole, and an opening communicating with the rope hole is provided on the double-layer composite bag mouth. After the locking rope extends out of the opening and is tied to seal the installation tube bag, the protective cavity forms a closed GIS installation and maintenance space.

[0006] As can be seen from the above scheme, the locking rope moves within the rope hole to tighten the double-layer composite bag opening. The protective cavity is used by workers to perform installation work inside. This utility model, through the tightenable installation tube bag, can be applied to tank flanges of different pipe diameters. After the protective cavity forms a closed GIS installation and maintenance space, it prevents floating dust from being generated inside the dustproof shed, thus affecting the maintenance of GIS equipment.

[0007] An inflation fan is connected to the inflation port via an air pipe.

[0008] The protective cavity is equipped with a temperature and humidity sensor, a detection meter, and a monitor. The temperature and humidity sensor and the detection meter are electrically connected to the monitor, respectively.

[0009] The protective membrane includes an air column frame and a canopy laid on the air column frame, with the air column frame located at the corners of the protective cavity.

[0010] The locking cord is equipped with a fixing device, which includes a housing, a pressing member disposed within the housing, and an elastic member connecting the housing and the pressing member. The housing is provided with a movable cavity adapted to the pressing member, and the pressing member is slidably disposed within the movable cavity. Two sets of first connecting holes are arranged in parallel through the housing, and the pressing member is provided with a second connecting hole corresponding to the first connecting holes.

[0011] The pressing member is provided with limit posts 821 at the bottom of both sets of the second connecting holes, and the elastic member includes two sets of spring members sleeved on the two sets of limit posts.

[0012] The observation window is made of transparent material. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figures 1 to 4As shown, this utility model is an inflatable cleanroom, including a protective membrane 1, a protective cavity 2 inside the protective membrane 1, an observation window 3 and an inflation port 4 on the protective membrane 1, the observation window 3 being made of transparent material, and installation tube bags 5 integrally formed on both sides of the protective membrane 1, the opening edge of the installation tube bag 5 having a double-layer composite bag opening 51, a rope hole being provided inside the double-layer composite bag opening 51, a locking pull rope 6 being threaded through the rope hole, and an opening 52 communicating with the rope hole on the double-layer composite bag opening 51, the locking pull rope 6 extending out of the opening 52 and tightening to seal the installation tube bag 5, the protective cavity 2 forming a closed GIS installation and maintenance space. In this embodiment, the top of the protective membrane 1 has an entrance for personnel to enter through a zipper, and a lining 13 is provided on the outside of the zipper for the entrance. The protective membrane 1 is provided with a small cloth tube, and the opening of the small cloth tube is provided with a filter cloth to allow air circulation between the inside and outside of the cabin.

[0020] The opening 52 includes two sets arranged side by side on the same side, and the two ends of the locking rope 6 extend from the two openings 52 respectively.

[0021] An air inlet 4 is connected to an air blower 7 via an air pipe.

[0022] The protective cavity 2 is equipped with a temperature and humidity sensor, a detection meter, and a monitor. The temperature and humidity sensor and the detection meter are electrically connected to the monitor.

[0023] The protective membrane 1 includes an air column frame 11 and a canopy 12 laid on the air column frame 11. The air column frame 11 is located at the corner of the protective cavity 2. In this embodiment, the canopy 12 is made of PVC material, and the observation window 5 is made of TPU transparent film. In another embodiment, the protective membrane 1 is made of soft cloth material.

[0024] The locking cord 6 is equipped with a retainer 8. The retainer 8 includes a housing 81, a pressing member 82 disposed within the housing 81, and an elastic member 83 connecting the housing 81 and the pressing member 82. The housing 81 is provided with a moving cavity 811 adapted to the pressing member 82. The pressing member 82 is slidably disposed within the moving cavity 811. Two sets of first connecting holes 84 are arranged in parallel through the housing 81.

By pressing down on the pressing member 82, the first connecting holes 84 and the second connecting holes 85 gradually overlap, facilitating the movement and adjustment of the locking pull rope 6. At this time, the elastic member 83 is in a compressed state. After adjustment, the pressing member 82 is released, the elastic member 83 returns to its original position, and the first connecting holes 84 and the second connecting holes 85 alternately lock the locking pull rope 82, thereby fixing the installation tube bag 5 and the tank flange. In another embodiment, the housing 81 has a groove on the inner wall of the moving cavity 811, and the pressing member 82 is provided with a sliding strip adapted to the groove. When the pressing member 82 is manually pressed and when the pressing member 82 returns to its original position, the sliding strip slides on the groove to guide the movement.

[0026] The workflow of this utility model is as follows: First, open the installation tube bag 5 and place it on the flange of the tank to be worked on. Secure it to the tank flange by tightening the locking rope 6. Use an external air inflator 7 to inflate the membrane cloth into a three-dimensional "cabin".
