Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fuel cells, and particularly relates to a pipeline cabin-penetrating sealing device. BACKGROUND

[0002] With the popularization of hydrogen fuel cell power generation applications, its safety has attracted widespread attention. While the system integration degree is greatly improved, how to prevent hydrogen leakage and how to avoid open flames become particularly important.

[0003] Hydrogen fuel cell power generation needs to go through a series of power conversion and control to output the required stable direct current or alternating current. In the same system, how to effectively isolate the gas preparation equipment from the power conversion equipment to prevent hydrogen from diffusing into the electrical equipment when hydrogen leaks, therefore, how to effectively seal the pipelines between the electrical equipment and the hydrogen-related equipment is particularly important.

[0004] Currently, a partition wall is usually used to isolate hydrogen-related equipment from non-hydrogen-related equipment. However, cables and pipelines must be connected through the partition wall, and a wire hole is needed to pass through the partition wall so that the cables and pipelines can pass through. In order to prevent hydrogen leakage to non-hydrogen-related equipment and cause a fire, the wire hole needs to be strictly sealed. The existing method is to seal the wire hole by fixing sealant in the wire hole. This method has a long curing time and can only be sealed once. Once damaged, it cannot be quickly repaired.

[0005] Therefore, there is an urgent need for a pipeline cabin-penetrating sealing device to solve the problem of long curing time of the wire hole sealed by the cables and pipelines passing through the wire hole by the sealant. SUMMARY

[0006] In view of the above analysis, the embodiments of the present application aim to provide a pipeline cabin-penetrating sealing device to solve the problem of long curing time of the wire hole sealed by the existing method of fixing sealant in the wire hole.

[0056] Example 3

[0057] Another specific embodiment of the cabin penetrating device of the present application is shown in Figure 5 The hole sealing unit of the cabin penetrating device of the present embodiment is improved compared with the hole sealing unit of example 1 or example 2, and the first sealing ring 3 and the second sealing ring 4 are replaced.

[0058] Preferably, the hole sealing unit of the cabin penetrating device of the present embodiment comprises a sealing tube 9, the sealing tube 9 can be sleeved on the first sleeve 1, and the sealing tube 9 is used to block the gap between the first sleeve 1, the second sleeve 2 and the wire hole. Compared with the installation of the first sealing ring 3 and the second sealing ring 4 of example 1 or example 2, it is more convenient to install a single part of the sealing tube 9.

[0059] Preferably, as Figure 6As shown, the sealing tube 9 is a circular tube, including a first sealing flange 91, a second sealing flange 92, and a telescopic part 93, which is disposed between the first sealing flange 91 and the second sealing flange 92. The first sealing flange 91 is used to seal the gap between the first sleeve 1 and the wire passage hole, and the second sealing flange 92 is used to seal the gap between the second sleeve 2 and the wire passage hole. The telescopic part 93 is a corrugated tube and has elasticity, and is used to keep the distance between the first sealing flange 91 and the second sealing flange 92 constant. After the sealing tube 9 is inserted into the wire passage hole, the first sealing flange 91 and the second sealing flange 92 can automatically fit against the bulkheads at both ends of the wire passage hole due to the pull of the telescopic part 93, facilitating the installation of the through-cabin device in this embodiment.

[0060] Preferably, the sealing tube 9 is an elastic sealing tube. Specifically, the sealing tube 9 is a rubber sealing tube, which provides a better sealing effect.

[0061] Preferably, such as Figure 5 As shown, the hole sealing unit of the through-cabin device in this embodiment also includes a tensioning cylinder 10. The tensioning cylinder 10 is disposed between the sealing tube 9 and the first sleeve 1. The tensioning cylinder 10 is used to expand the sealing tube 9 so that the outer wall of the sealing tube 9 is connected to the inner wall of the wire hole, thereby enhancing the sealing effect of the sealing tube 9 on the wire hole and strengthening the connection between the through-cabin device and the wire hole in this embodiment.

[0062] Preferably, such as Figure 7 As shown, the outer diameter of the first sleeve end is smaller than the outer diameter of the first sealing end. The tensioning cylinder 10 is coaxial with the central axis. The tensioning cylinder 10 includes a tensioning block 101 and a tensioning cylinder body 102. The tensioning block 101 is disposed at one end of the tensioning cylinder body 102, and the outer wall of the tensioning block 101 can connect with the inner wall of the sealing tube 9. There are multiple tensioning blocks 101, which are evenly distributed circumferentially on the tensioning cylinder body 102.

[0063] During the connection of the first sleeve 1 and the second sleeve 2, the tensioning block 101 is connected to the inner surface of the sealing tube 9 by a point or line. In some optional embodiments, to prevent the tensioning block 101 from damaging the inner surface of the sealing tube 9, such as... Figure 8As shown, the tensioning cylinder 10 is an elastic straight cylinder, the first sleeve end can be connected with one end of the tensioning cylinder 10, and the one end of the tensioning cylinder 10 is supported to open the sealing pipe 9, and the outer wall of the sealing pipe 9 is connected with the inner wall of the wire hole. When the first sleeve end is connected with one end of the tensioning cylinder 10, one end of the elastic straight cylinder can be evenly opened, and the connection between the elastic straight cylinder and the sealing pipe 9 is a surface connection, which prevents the tensioning cylinder 10 from causing extrusion damage to the inner surface of the sealing pipe 9.

[0064] Compared with the installation of the first sealing ring 3 and the second sealing ring 4 in the first embodiment or the second embodiment, the installation of the single sealing pipe 9 is more convenient; after the sealing pipe 9 is inserted into the wire hole, the first sealing flange 91 and the second sealing flange 92 can be automatically attached to the bulkhead at both ends of the wire hole due to the pulling of the elastic part 93, which facilitates the installation of the cabin-penetrating device of the present embodiment; the tensioning cylinder 10 is used to support the sealing pipe 9 to connect the outer wall of the sealing pipe 9 with the inner wall of the wire hole, thereby enhancing the sealing effect of the sealing pipe 9 on the wire hole and the firmness of the connection between the cabin-penetrating device of the present embodiment and the wire hole.

[0065] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any changes or replacements within the technical scope disclosed by the present application can be easily thought by those skilled in the art, and should be covered within the protection scope of the present application.
