DETAILED DESCRIPTION

[0019] like Figure 1-4 The utility model provides a floating valve sealing structure for inspecting a lock chamber, comprising a floating valve 1, a side sealing structure 3 arranged on both sides of the floating valve 1, and a bottom sealing structure 2 arranged at the bottom edge of the floating valve 1, the two ends of the side wall of the floating valve 1 close to the lock chamber are connected with an extension section 4, the extension section 4 is perpendicular to the floating valve 1, an airbag auxiliary sealing structure 5 is arranged at the bottom of the inner side wall of the floating valve 1, and both ends of the airbag auxiliary sealing structure 5 are provided with vertical sections and are respectively connected to the bottom of the side wall of the extension section 4.

[0020] When placing the floating door 1, first determine the adaptation of the side sealing structure 3 on both sides of the floating door 1 and the matching structure on the inner wall of the lock chamber, and then flush the ballast tank in the floating door 1 to make the floating door 1 descend and seal the lock chamber. Since the side wall of the floating door 1 close to the lock chamber is connected with an extension section 4, the extension section 4 increases the length of the end face of the floating door 1, so that the main body of the floating door 1 can move forward relative to the lock chamber, so that the bottom structural seam of the lock chamber that was originally blocked by the floating door 1 after it descends is moved backward relative to the floating door 1, so that the floating door 1 will not cover the bottom structural seam of the lock chamber after it sits on the bottom, which is convenient for the staff to inspect the structural seam.

[0021] A bottom sealing structure 2 is arranged around the edge of the bottom of the floating gate 1, and a rubber strip is arranged inside the bottom sealing structure 2. After the floating gate 1 is pressed down on the bottom of the gate chamber, the bottom sealing structure 2 is in full contact with the bottom surface of the gate chamber to achieve sealing inside the gate chamber.

[0022] After the bottom sealing of the floating valve 1 is completed, the air supply unit is controlled to inflate the airbag auxiliary sealing structure 5, so that the airbag in the airbag auxiliary sealing structure 5 expands, filling the gap between the bottom of the floating valve 1 and the bottom surface of the gate chamber, and the bottom surface of the airbag auxiliary sealing structure 5 is fully attached to the bottom surface of the gate chamber to achieve effective sealing.

[0023] like Figure 3 The airbag auxiliary sealing structure comprises a mounting shell 51 fixedly arranged at the bottom of the floating valve 1, a slideway is vertically arranged in the mounting shell 51, a sealing airbag 53 is slidably arranged in the slideway, an inflation chamber 52 is arranged in the sliding space above the sealing airbag 53, and the inflation chamber 52 is connected to an external air supply unit through a pipeline.

[0024] When the airbag auxiliary sealing structure 5 is sealing, air is delivered into the inflation chamber 52, and the air squeezes the sealing airbag 53 downward through the inflation chamber 52, so that the sealing airbag 53 slides downward on the vertical slide in the mounting shell 51, and the bottom end of the sealing airbag 53 is fully attached to the bottom plate of the gate chamber, thereby realizing the auxiliary sealing of the airbag.

[0025] like Figure 3 As shown. A compression chamber 54 is provided at the bottom of the sealing airbag 53, and compressed gas is filled in the compression chamber 54. When the sealing airbag 53 is compressed downward by inflation, the sealing airbag 53 moves downward and fits against the bottom plate of the lock chamber. When the airbag 53 is further compressed, the sealing airbag 53 is further compressed, thereby compressing the compression chamber 54, and the bottom of the sealing airbag 53 fits more closely against the bottom plate of the lock chamber.

[0026] like Figure 2As shown. The bottom sealing structure 2 includes a mounting seat 11 fixed to the bottom of the floating valve 1, fixed blocks 12 fixed to both sides of the mounting seat 11, and a sealing strip 13 arranged between the two fixed blocks 12. The mounting seat 11 is fixedly welded to the bottom of the floating valve 1, and the fixing blocks 12 are respectively installed on the inner and outer sides of the mounting seat 11. The sealing strip 13 is protected and supported by the two fixing blocks 12; when sealing, the sealing strip 13 is compressed to ensure a tight fit between the sealing strip 13 and the bottom plate of the gate chamber.

[0027] like Figure 2 A gap is provided between the sealing strip 13 and the fixing block 12, and the bottom surface of the sealing strip 13 is located below the bottom surface of the fixing block 12. The sealing strip 13 undergoes a certain deformation after being compressed, and a gap is reserved between the sealing strip 13 and the fixing block 12 to prevent the sealing strip 13 from being damaged.

[0028] like Figure 4 As shown. The side sealing structure 3 is vertically fixed on the side wall of the floating valve 1, and an adapting tooth 6 is fixedly provided on the gate chamber, and an adapting groove adapted to the side sealing structure 3 is provided in the middle of the adapting tooth 6. When the side of the floating valve 1 is sealed, the side sealing structure 3 is inserted into the adapting groove, and the side sealing of the floating valve 1 is achieved through the cooperation between the side sealing structure 3 and the adapting groove.
