Description

Technical Field

[0001] This utility model belongs to the field of pipeline sealing technology, specifically, it relates to a rapid sealing device for leaks in fire-fighting water supply pipelines. Background Technology

[0002] In pipeline operations that transport fluids, leaks can easily occur on the surface of pipes after prolonged use, causing the fluid inside the pipes to leak out. Timely leak sealing is necessary. Older buildings often use cast iron pipes (high strength, poor toughness), which are mostly aged after years of use. During construction, fire-fighting pipe breaks frequently occur, and fire valves often cannot be completely closed, making repairs extremely difficult. Conventional methods for repairing cast iron fire-fighting pipes involve completely cutting off the water flow in the broken pipe, breaking open the damaged valve area, and then repairing the pipe. This causes environmental damage and incurs high repair costs.

[0003] A document with publication number (CN218294927U) discloses a pipe sealing device, including a clamp, a top screw, and a rubber-lined sealing plate. The clamp includes a suspension plate and an adjustment plate. The bottom of the suspension plate is hinged to two adjustment plates at its bottom via a first hinge. The rubber-lined sealing plate is fixed to the top of the top screw. The top screw is pushed upward to make the rubber-lined sealing plate fit tightly against the pipe for sealing, which can conveniently and quickly plug the leak.

[0004] It is only suitable for sealing leaks in general low-pressure pipelines. When used in high-pressure, high-flow pipelines such as fire-fighting pipelines, it is prone to leakage due to the high internal pressure of the pipeline. It is only suitable for sealing leaks in general small holes.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0016] Compared with the prior art, the present invention has the following advantages:

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] Please see Figure 1-5 A rapid leak sealing device for fire water supply pipelines includes a mounting plate 1, a fixing hoop 11 fixedly connected to the bottom of the mounting plate 1, a screw 15 rotatably connected to the mounting plate 1, a movable hoop 12 threadedly connected to the screw 15, the movable hoop 12 slidably connected to the mounting plate 1, a sealing plate 13 provided inside the movable hoop 12, a supply block 4 provided on the mounting plate 1, the sealing plate 13 and the supply block 4 are connected, and the fixing hoop 11 and the movable hoop 12 are connected by fasteners.

[0029] In operation, the fixed clamp 11 and the movable clamp 12 are first adjusted to separate by a certain distance. Then, the fixed clamp 11 is placed at the bottom of the fire-fighting pipeline. The screw 15 is then manually rotated, and the screw 15 drives the movable clamp 12 to move toward the fixed clamp 11 through the thread until the fixed clamp 11 and the movable clamp 12 are in contact or maintain a suitable position. The fixed clamp 11 and the movable clamp 12 are then connected with fasteners. The position of the sealing plate 13 is then adjusted to ensure that the sealing plate 13 is tightly in contact with the leaking location of the fire-fighting pipeline, thus sealing the leak. Through the internal design of this device, the pressure at the leaking location of the fire-fighting pipeline can be distributed, reducing secondary damage to the fire-fighting pipeline caused by excessive pressure. Furthermore, the tight sealing of the sealing plate 13 can seal large-area leaks.

[0030] The upper edge of the screw 15 is provided with a telescopic rod 14, which is slidably connected to the screw 15. The mounting plate 1 has an installation position. The movable hoop 12 is fixedly connected to the mounting frame 2. The screw 22 is rotatably connected inside the mounting frame 2. The threads at both ends of the screw 22 are arranged in opposite directions. Sliding blocks 23 are symmetrically arranged on the screw 22. Each sliding block 23 is slidably connected to the mounting frame 2 and threadedly connected to the screw 22. Each sliding block 23 is rotatably connected to the bottom of the sliding block 23 and rotatably connected to the corresponding position of the sealing plate 13. The mounting frame 2 is fixedly connected to the drive motor 21, and the output end of the drive motor 21 is connected to the screw 22 through a coupling.

[0031] In operation, after adjusting and separating the fixed clamp 11 and the movable clamp 12 by a certain distance, the fixed clamp 11 is placed at the bottom of the fire-fighting pipe. Then, the telescopic rod 14 is manually pulled upwards. By rotating the telescopic rod 14, the screw 15 is driven. The screw 15 drives the movable clamp 12 towards the fixed clamp 11 through the thread until the fixed clamp 11 and the movable clamp 12 are in contact or maintain a suitable position. Then, the fixed clamp 11 and the movable clamp 12 are connected by fasteners. Then, the position of the sealing plate 13 is adjusted, and the output end of the drive motor 21 is connected through a coupling. The screw 22 rotates, and the screw 22 drives the symmetrical sliding blocks 23 to move towards each other through the thread. The sliding blocks 23 drive the swing block 24 to change its angle, and the swing block 24 drives the sealing plate 13 to rise and fall, so that the sealing plate 13 fits tightly with the location of the fire pipeline leak, thus sealing the leak location of the fire pipeline. Through the internal design of this device, the pressure at the leak location of the fire pipeline can be distributed, reducing the secondary damage to the fire pipeline caused by excessive pressure. Moreover, the sealing plate 13 can seal large-area leaks.

[0032] The mounting plate 1 is fixedly connected to a fixing plate 3, the fixing plate 3 is rotatably connected to a threaded rod 31, the threaded rod 31 is threadedly connected to a knob 32, and the knob 32 is rotatably connected to a plate.

[0033] The plate abuts against an airbag 33, which is penetrated by a threaded rod 31. The airbag 33 is fixedly connected to the fixing plate 3, and the airbag 33 is symmetrically connected to a connecting tube 41.

[0034] The middle part of the connecting pipe 41 is fixedly connected to the supply block 4, the supply block 4 is fixedly connected to the supply pipe 42, and the connecting pipe 41 is connected to the sealing plate 13.

[0035] After the sealing plate 13 is tightly attached to the wall of the fire pipeline, sealant is manually injected into the supply pipe 42. Then, the knob 32 is manually turned. The knob 32 moves on the threaded rod 31 through the threaded rotation and compresses the air bag 33. The air bag 33 injects the gas inside into the supply block 4. The sealant injected into the supply block 4 through the supply pipe 42 is injected into the space between the sealing plate 13 and the wall of the fire pipeline through the connecting pipe 41. This sealant is cured and plugged at the leak location, and the gap between the sealing plate 13 and the wall of the fire pipeline is filled, improving the sealing effect of the device.

[0036] Working Principle: In operation, after adjusting and separating the fixed clamp 11 and movable clamp 12 by a certain distance, the fixed clamp 11 is placed at the bottom of the fire-fighting pipeline. Then, the telescopic rod 14 is manually pulled upwards. Rotating the telescopic rod 14 drives the screw 15, which in turn drives the movable clamp 12 towards the fixed clamp 11 through its thread, until the fixed clamp 11 and movable clamp 12 are in contact or maintain a suitable position. The fixed clamp 11 and movable clamp 12 are then connected using fasteners. Next, the position of the sealing plate 13 is adjusted. The output end of the drive motor 21 drives the lead screw 22 to rotate through a coupling. The lead screw 22, through its thread, drives the symmetrical sliding blocks 23 to move towards each other. The sliding blocks 23 change the angle of the swing block 24, which in turn causes the sealing plate 13 to rise and fall, ensuring a tight seal between the sealing plate 13 and the leaking location in the fire-fighting pipeline, thus eliminating the leak. This device seals leaks in fire-fighting pipelines. Its internal design distributes pressure at leak points, reducing secondary damage caused by excessive pressure. The sealing plate 13 effectively seals large-area leaks. After the sealing plate 13 is tightly fitted to the fire-fighting pipeline wall, sealant is manually injected into the supply pipe 42. Then, the knob 32 is manually turned, moving along the threaded rod 31 and compressing the airbag 33. The airbag 33 injects its internal gas into the supply block 4. The sealant injected into the supply block 4 through the supply pipe 42 is then injected through the connecting pipe 41 into the space between the sealing plate 13 and the fire-fighting pipeline wall. This sealant hardens and fills the gap between the sealing plate 13 and the fire-fighting pipeline wall, improving the sealing effect of the device.
