Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline emergency repair technology, specifically a rapid deployment device for ventilation ducts at gas pipeline emergency repair sites. Background Technology

[0002] In emergency repairs of urban gas pipelines, forced ventilation is required when: gas leaks and accumulates in large quantities; gas concentrations exceed standards around the work site; gas seeps into buildings; environmental concentrations are within the range of explosive and toxic concentrations; work is being carried out in contaminated areas; or gas concentrations are within the explosive range. This is necessary to prevent personnel from being poisoned or suffocated, eliminate explosion and fire hazards, ensure the continued safety of repair work, and reduce the spread of gas.

[0003] However, existing devices have the following problems: Currently, the main method of forced ventilation is to use folded ducts and fans to draw high-concentration gas from the repair site to an open outdoor area. Due to explosion-proof requirements at the repair site, the fans are placed in an open outdoor area far from the site. The high-concentration gas is transported away from the site by creating negative pressure inside the folded ducts through air extraction. However, in reality, the folded ducts will gradually shrink due to the air extraction action of the fans. If no one controls the ducts, they will be far away from the repair site and will not be able to perform the air extraction function. In addition, the repair tasks are urgent and the scene is complex. The existing folded ducts are stored and deployed on site arbitrarily, without corresponding structure for management, which makes the duct layout inconvenient, difficult to implement at the repair site, and results in poor ventilation.

[0004] To address this, we propose a rapid deployment device for ventilation ducts at gas pipeline emergency repair sites. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a rapid deployment device for ventilation ducts at gas pipeline emergency repair sites. It features unified storage, easy portability, rapid deployment, stable folding of the duct after connection with a fan to ensure ventilation at the repair site, and convenient operation without hindering on-site repair work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid deployment device for ventilation ducts at gas pipeline emergency repair sites, comprising a folding fixing frame, an adjustable support frame rotatably connected to the rear surface of the folding fixing frame, a connecting rod rotatably connected to the outer surface of the adjustable support frame, the other end of the connecting rod rotatably connected to the folding fixing frame, two clips provided on the folding fixing frame, a folding duct detachably connected to the folding fixing frame, a fan fixedly connected to the rear end of the folding duct, a rope knot provided on the folding fixing frame, and rubber pads provided at the connection points of the folding fixing frame, the adjustable support frame, and the connecting rod.

[0007] Preferably, the output end of the fan is fixedly connected to the folded air duct.

[0008] Preferably, the folded air duct is fixedly installed on the folding fixing frame by a clamp.

[0009] Preferably, the folding fixing frame is equipped with a handle, and the knot is located on the handle.

[0010] Preferably, the connecting rod includes two first rotating shafts, two connecting rods, and a second rotating shaft.

[0011] Preferably, the two first rotating shafts are respectively fixedly connected to the adjustable support frame and the folding fixing frame, and the outer surfaces of the two first rotating shafts are respectively rotatably connected to a connecting rod, and the two connecting rods are rotatably connected through a second rotating shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model achieves unified storage, easy portability, and rapid deployment. All equipment components are uniformly stored, reducing on-site searching and disassembly time. It can be transported to the site in one trip, reducing the time cost of personnel team building and transportation. After connecting to the fan, it can stabilize the folded duct posture, ensuring the ventilation effect at the repair site, reducing the swaying and deformation of the duct in the construction area, maintaining a stable air direction and air volume. The stable posture helps to achieve continuous and uniform air supply, reducing secondary safety hazards caused by local wind pressure fluctuations. It is also easy to operate, does not hinder on-site repair work, reduces obstruction to the work surface, and quickly deploys to shorten the time exposed to odors and harmful gases, improving on-site safety.

An adjustable support frame 2 is rotatably connected to the rear surface of the folding fixing frame 1. The angle of the adjustable support frame 2 is equivalent to the posture angle of the folding duct 5, which can quickly adjust the exhaust posture on site. A connecting rod 3 is rotatably connected to the outer surface of the adjustable support frame 2. The other end of the connecting rod 3 is rotatably connected to the folding fixing frame 1. Two clips 4 are provided on the folding fixing frame 1. The clips 4 can fix the end of the folding duct 5 so that it does not retract when the fan 6 is ventilating, thus stabilizing its posture and maintaining ventilation at the emergency repair site.

[0017] A folding air duct 5 is detachably connected to the folding fixing frame 1. A fan 6 is fixedly connected to the rear end of the folding air duct 5. A rope knot 7 is provided on the folding fixing frame 1. The folded air duct can be uniformly stored by the rope knot 7. Personnel can lift the handle of the folding fixing frame 1 and leave. It is space-saving, quick and convenient. Rubber pads 8 are provided at the connection points of the folding fixing frame 1, the adjustable support frame 2, and the connecting rod 3 to prevent friction during the folding process and for explosion-proof considerations.

[0018] Specifically, the output end of the fan 6 is fixedly connected to the folded air duct 5.

[0019] Furthermore, the folded air duct 5 is fixedly installed on the folding fixing frame 1 by the clip 4.

[0020] Furthermore, a handle is installed on the folding fixing frame 1, and the knot 7 is located on the handle.

[0021] It is worth noting that the connecting rod 3 includes two first rotating shafts, two connecting rods, and a second rotating shaft.

[0024] Working principle: In the event of an emergency repair of a city gas pipeline, when a large amount of gas leaks and accumulates, the blower 6 is placed in an open outdoor area away from the site. The blower 6 uses suction to create negative pressure inside the folded duct 5 to transport high-concentration gas away from the site over a long distance. Then, the folded fixing frame 1 is placed at the location of the high-concentration gas, and the adjustable support frame 2 is pulled out. The adjustable support frame 2 rotates and extends, ensuring the stability of the folded fixing frame 1. The folded fixing frame 1 and the adjustable support frame 2 are connected and reinforced by the connecting rod 3. Finally, the folded duct 5 is clamped around its circumference by clamps 4. Figure 1 As shown, the position of the folded air duct 5 is fixed and the position of the folded air duct 5 is ensured to be stable. Rubber pads 8 are provided at the folding and connecting positions of the folding fixing frame 1. The rubber pads 8 reduce the friction during the folding process. When not in use, the folded adjustable support frame 2 and connecting rod 3 are retracted, the clamp 4 is loosened, and then the entire device can be lifted by the rope knot 7. It can be carried away by hand.
