Problems solved by technology

For the factory buildings that need to transport large-scale equipment, the size of the door opening is relatively large (the size of the door opening of this test factory is 8.5 meters × 5.4 meters), if the traditional airtight door structure is used to block the door opening, there will be complex structures and a long construction period problems, and due to the high quality of the airtight door, it is difficult to guarantee the pressure tightness and safety of the airtight door

Embodiment 1

[0086] The hole sealing door device in this embodiment includes a hole sealing door, a first locking mechanism and a first sealing mechanism.

[0087] Wherein, the area of ​​the hole sealing door is larger than that of the hole, and the edge of the hole sealing door is in contact with the wall at the edge of the hole to close the hole.

[0088] Such as figure 1 As shown, the hole sealing door includes a hole sealing door panel 1 and a hole sealing door bottom plate 25, wherein the direction of the hole sealing door panel 1 is perpendicular to the direction of the hole sealing door bottom plate 25, and the hole sealing door panel 1 is sealed with the hole. The door bottom plate 25 is fixedly connected.

[0089] The first locking mechanism includes a first front locking unit and a first rear locking unit. The first front locking unit is used to lock the hole sealing door panel 1 and the wall from the front of the hole sealing door.

[0090] Specifically, in this embodiment, t...

Embodiment 2

[0107] This embodiment provides a hole sealing door device, the structure of which is the same as that of the hole sealing door device described in Embodiment 1. The difference between the two is that in this embodiment, the hole sealing door panel 1 is provided with a transportation channel door opening , the door opening of the transportation passage door is closed by the transportation passage door.

[0108] Such as figure 1 As shown, the transportation passage door includes a transportation passage door panel 4 and a transportation passage door bottom plate 26, wherein the direction of the transportation passage door door panel 4 is perpendicular to the direction of the transportation passage door bottom plate 26, and the transportation passage door door panel 4 and the transportation passage door bottom plate 26 are perpendicular to each other. The transport channel door bottom plate 26 is fixedly connected.

[0109] Wherein, the area of ​​the transportation passage door...

Embodiment 3

[0139] This embodiment provides a transport method for transporting large-scale equipment to the nuclear test plant, including the following steps:

[0140] S11, installing the hole sealing door device as described in embodiment 1 or embodiment 2 at the hole position of the nuclear test building;

[0141] S12, inspect the airtightness of the hole sealing door device, and then inspect the airtightness of the nuclear test plant until the inspection is qualified;

[0142] S13, remove the hole seal door from the hole, and transport the large equipment to the nuclear test plant;

[0143] S14, reinstalling the hole sealing door to the hole, and using concrete to block the hole sealing door device.

[0144] In this embodiment, the size of the large door opening of the nuclear test plant is 8.5 meters * 5.4 meters, and then the opening sealing door device as described in embodiment 1 or embodiment 2 is installed on the door opening. Wherein, in step S12, the specific operation proce...

Abstract

The invention discloses a hole sealing door device which includes a hole sealing door, a first locking mechanism and a first sealing mechanism. The area of the hole sealing door is larger than the hole area, the hole sealing door includes a hole sealing door plate and a hole sealing door bottom plate, the first locking mechanism comprises first front face locking units and first back face lockingunits, the first front face locking units are used for locking the hole sealing door plate and a wall from the front face of the hole sealing door, and the first back face locking units are used for locking the hole sealing door plate and the wall from the back side of the hole sealing door; and the first sealing mechanism comprises first hole sealing gaskets which are arranged between the hole sealing door plate and the wall and between the hole sealing door plate and the hole bottom. Correspondingly, a transportation method is also provided. The problems that the size of a sealing door in the prior art is small, if the sealing door needs to adapt to a large-sized door hole, the structure is complicated, the construction period is long, and it is difficult to ensure the sealing performance and safety are solved.

Description

technical field [0001] The invention belongs to the technical field of nuclear facilities, and in particular relates to a hole sealing door device and a transportation method. Background technique [0002] The door is an indispensable equipment for the nuclear facility test plant. On the one hand, the door is required to be a part of the pressure boundary of the plant to withstand the load of the test pressure of the plant to ensure the airtightness and safety of the plant. On the other hand, during the installation, maintenance and trial operation of test equipment, it is necessary to transport large equipment into the factory building. Therefore, this type of door needs to be able to temporarily block and test on the basis of the original opening of the plant, have the airtightness and safety required by the nuclear facility test plant, and meet the requirements for the entry and exit of large equipment. [0003] The size of the existing airtight doors is usually small, a...
