[0002] A pressure vessel is a closed device used to contain gas or liquid and bear a certain pressure. It plays an important role in many sectors such as industry, civil, military industry, and many fields of scientific research.

[0003] For example, a pressure vessel inspection and detection device and method of use with publication number CN115266729B uses a pull rope, a support sleeve, a spiral groove and other components in coordination. When the pull rope is wound, the support sleeve and the movable sleeve are translated on the surface of the support rod through the connecting bearing. When the movable sleeve is translated, the guide rod and the spiral groove are used in coordination to make the movable sleeve achieve the effect of translation and rotation, so that the micro camera can perform a comprehensive inspection of the inner wall of the tank body. However, in actual use, the inner wall of the pressure vessel is inspected by moving and rotating the micro camera. During the use of the pressure vessel, various sediments, corrosion products and dirt may be attached to its inner wall. If these debris are not cleaned up, it will directly affect the accuracy of the test results. If the pressure vessel is overlooked, if the corrosion area is not cleaned, the overlooking range cannot be accurately and intuitively detected, and there are certain use defects.

[0028] 1. A detection component is arranged inside the pressure vessel body. When the inner wall of the pressure vessel body is detected, the pull block is pulled to drive the sliding rod to slide inside the sliding groove, so that the telescopic spring can be stretched. When the sliding rod moves, the connecting block is driven to slide inside the movable groove, so that the movable rod can be pulled to rotate, so that the movable frame is moved to drive the support rod to rotate, and the rotating rod is inserted into the interior of the pressure vessel body so that the mounting block fits one side of the interior of the container, and the threaded sleeve is fixed. The pull block is loosened to move the movable frame so that the roller fits the inner wall of the pressure vessel body, and the telescopic spring is in a stretched state, so that the roller is in close contact with the inner wall of the pressure vessel body, and the turntable is rotated to drive the rotating rod to rotate. After the rotating rod rotates, it can move through the connection between the thread line and the threaded sleeve, so that the micro camera on the mounting block rotates and moves, so that the inner wall of the pressure vessel body can be fully detected. The rotating rod drives the movable frame While the circular rotation is being performed, the sponge sleeve on the roller is fitted with the inner wall of the pressure vessel body to make the roller rotate, drive the rotating shaft to rotate, and drive the rotating shaft to rotate through the meshing of the first bevel gear and the second bevel gear, and then drive the rotating rod to rotate through the connection between the first pulley and the second pulley, so that the disc rotates, and after the disc rotates, it drives the column block to rotate in a circular manner, so that the column block can be connected with the mounting frame through sliding to drive the mounting frame to move back and forth, so that the column rod can move back and forth, so that the cleaning plate can be driven to move back and forth, so that the non-woven fabric on the cleaning plate cleans the inner wall of the pressure vessel body, and the inner wall of the pressure vessel body can be cleaned while the inner wall of the pressure vessel body is being inspected through the detection component, and the surface covering is cleaned, so as to improve the accuracy of the detection, and after cleaning the inside, tiny surface defects, such as fine cracks and corrosion points, can be observed more clearly, so as to improve the detection effect;

[0029] 2. The column rod can drive the movable block to move back and forth while performing reciprocating movement. The movable block can slide inside the triangular groove while performing reciprocating movement. The movement of the movable block can push the positioning block to slide inside the installation groove to compress the reset spring. After the movable block passes through the positioning block, the reset spring drives the positioning block to reset, thereby preventing the movable block from moving counterclockwise. The movable block slides inside the triangular groove so that the column rod can move along the triangular groove. During the movement, the column rod can drive the supporting sleeve to slide on the limiting rod, drive the positioning rod to slide on the movable frame, and limit the movement of the column rod, so that when the movable block moves to the inclined surface of the triangular groove, the cleaning plate can be driven not to fit with the inner wall of the pressure vessel body, so that the cleaning plate moves to the left during the reciprocating movement to avoid fitting with the inner wall of the pressure vessel body, and prevents the cleaning plate from bringing back the cleaned stains after moving to the right, so that during the detection of the inner wall of the pressure vessel body, the cleaning effect of the cleaning plate is not ideal, which affects the detection accuracy;

[0030] 3. A fixing assembly is set on the outside of the inlet. By putting the fixing cover on the outside of the inlet and rotating the two fixing bolts to drive the clamping block to move, the rubber pad on the clamping block can fit tightly with the inlet on the pressure vessel body, and then the fixing cover can be fixed on the outside of the inlet, which is convenient for subsequent inspection of the inner wall of the pressure vessel body.
