Description

Weld tightness inspection device Technical Field The utility model relates to the technical field of weld tightness inspection, in particular to a weld tightness inspection device. Background During sailing, ships are subjected to various environmental factors such as sea waves, sea wind, corrosion and the like, which can cause damage or failure of ship structures, equipment and systems. And the weld joint is used as a key part of ship structural connection, and the tightness of the weld joint is directly related to the safety and normal operation of the ship. Therefore, the ship maintenance detection and weld tightness detection are required to be carried out regularly, on one hand, the problems of the welded parts of the ship body can be found in time and repaired, the integrity and the tightness of the ship structure are ensured, the navigation safety of the ship is ensured, on the other hand, the service lives of equipment and a system can be prolonged, and the maintenance and replacement cost caused by the weld problems is reduced. In addition, the problem of weld tightness is found and solved in time, the navigation stoppage and delay caused by equipment faults can be avoided, and the operation efficiency of the ship is improved. At present, a non-closed cabin welding seam tightness testing device made of organic glass is generally used, the structure of the device is composed of a cover body, then a circle of sealant is arranged at the bottom of the cover body, when the device is used, the device is attached to a welding seam of a ship body to be tested, then a cavity in the cover body is vacuumized, the cover body is tightly pressed on the wall of the ship body by atmospheric pressure, the change of a pressure value is checked through a pressure gauge on the cover body, and the welding seam tightness is judged through the change of the pressure gauge. However, the technical problems are found in the long-term practical application that the shipbuilding factory is built at sea, the sealant of the cover body is easy to corrode and weather due to sea wind, and tiny cracks appear, so that the detection process of tightness of the welding seam is difficult to find, the change of the air pressure in the cover body is caused by the welding seam or the compactness problem of the cover body cannot be effectively judged, and the situation that the detection result is wrong can occur.
