example 1

[0042] see figure 1 , The leak plugging nail 100 provided in this example mainly includes two parts: a nail shaft 104 and a leak plugging sleeve 105 . The cross-section of the plugging sleeve 105 is "T" shape, and consists of a plugging cover 101 and a plugging rod 102 arranged on the plugging cover 101. The plugging cover 101 is used to compress and seal the outside of the leakage port, and Make the plugging rod 102 on it pass through the leakage port; and the nail rod 104 is movably inserted in the plugging sleeve 105 along the extension direction of the plugging rod, and its front end is covered with a plugging cap 103. When moving in the leak sleeve, the plugging cap 103 cooperates with the plugging rod in the plugging sleeve, and the port side wall of the plugging cap is driven by the plugging rod to deform as a whole facing the inner wall of the pipeline (that is, the direction of the leakage port). Compress and seal the inside of the leak over the leak.

[0068] see Figure 4 , The leak plugging nail 200 provided in this example mainly includes two parts: a nail shaft 204 and a leak plugging sleeve 205 . The cross section of the plugging sleeve 205 is "T" shape, mainly formed by the plugging cover 201 and the plugging rod 202 arranged on the plugging cover, the leak plugging cover 201 is used to compress and seal the outside of the leakage port, And make the plugging rod 202 on it pass through the leakage port. The nail rod 204 is movably installed in the leak plugging sleeve along the extension direction of the leak plugging rod 202, and a guide block 203 is arranged on the head thereof. When the nail rod moves in the leak plugging sleeve, the guide block 203 and the free end 202b of the leak plugging rod Cooperate, drive the free end of the plugging rod to deform as a whole facing the inner wall of the pipeline (that is, the direction of the leakage port), and make the deformation part compress from the inner side of the lea...

Abstract

The invention discloses a fire hose on-line under-pressure quick leaking stoppage nail and a quick leaking stoppage method. The leaking stoppage nail is inserted in a leaking opening. A nail rod of the leaking stoppage is matched with a leaking stoppage sleeve to deform so as to simultaneously compress and seal the leaking opening from the inner side and the outer side of the leaking opening, so that the leaking opening is blocked. The fire hose on-line under-pressure quick leaking stoppage nail is simple in structure and capable of realizing quick on-line leaking stoppage on a soft pipeline.

Description

technical field [0001] The invention relates to a pipeline plugging technology, in particular to an online pipeline plugging technology. Background technique [0002] The fire hose is an important equipment for the fire brigade to transport fire extinguishing agents, and plays a vital role in fire fighting and rescue. In fire fighting, fire hoses are often scratched due to aging materials or encountering sharp objects such as hard protrusions, resulting in damage and water leakage. The water leaking out under high pressure not only adversely affects fire fighting and rescue, but may also cause serious consequences. Especially in the fire rescue scene, once the main line hose breaks, it will directly affect the water supply in the front field. To replace the new hose, the water pump needs to be stopped, which wastes a lot of time. This is very undesirable for fire fighting and rescue where every second counts. At this time, there is a need for a method to block the leak of ...
