Description

Tank body internal sealing type plugging head for fire protection Technical Field The utility model relates to the field of a sealing type plugging head in a tank body for fire protection, in particular to a sealing type plugging head in a tank body for fire protection. Background When the tank body for storing and transporting oil, liquid chemicals and the like is cracked and leaked for some reason, fire-fighting officers need to use a blocking tool to block and seal the leakage position in an emergency way. Aiming at the problems in the prior art that the plugging head can not completely plug the split in time due to irregular shape of the cracking position in the prior art; in the prior art, some plugging tools are plugged into the gap from inside to outside by using a plug, but the plug is always pushed outwards by liquid in the tank, so that the plug is outwards displaced after a long time, the gap cannot be completely sealed by plugging loosening, and the original purpose of plugging the plug is not achieved, and therefore, structural innovation is needed to solve the specific problem; In the prior art, as disclosed in application publication number CN113623402A, the invention discloses an internal sealing type plugging head for a fire-fighting tank, which relates to the technical field of fire-fighting equipment and comprises a plugging head and a pressure rod, wherein the front end of the pressure rod is in threaded connection with the rear end of the plugging head, the plugging head comprises a plugging piece and a gas generating piece, the rear end of the plugging piece is fixedly connected with the front end of the gas generating piece, the rear end of the gas generating piece is in threaded connection with the front end of the pressure rod, the invention is combined through the plugging head and the pressure rod, the device has the advantages that a large amount of carbon dioxide gas generated after effervescent reaction of the effervescent disintegrating agent enters the inflatable part plugged into the inner wall of the split, the volume of the inflatable part is expanded and then clings to the inner wall of the tank body due to the extrusion force of liquid in the tank, the split is blocked from the inside, the situation that the split is extruded outwards by the liquid in the tank to cause sealing failure is avoided, and the released magnetic powder gathers towards the split due to the mutual magnetic attraction with the annular magnet at the outer side of the tank body, so that irregular split and tiny split can be filled and sealed; In the prior art, as in the above patent, the latex balloon is adopted to be extruded on the inner wall from the inner end in a one-way expansion way, the one-way seal is unstable, the mechanism is complex and easy to damage, and the cost is high.
