[0054] Embodiment 1

[0055] The present application provides a sealing device for sealing test, by which a process hole can be sealed; Figure 1 and Figure 2 A sealing device for sealing test provided by the present application is described in detail as follows:

[0056] In this embodiment, the sealing device for sealing test includes a sealing plate 1 and a fixing assembly.

[0057] Specifically, the sealing plate 1 is adapted to the process hole, and the adaptation here means that the sealing plate 1 is adapted to the process hole in shape and size, which is described in detail below by taking the example that the sealing plate 1 and the process hole are both elliptical.

[0058] Specifically, the fixing assembly includes a connecting portion 3, a pressing portion 4 and a locking portion 5; wherein, in combination with Figure 2As shown, the sealing plate 1 has a sealing end face 6 facing the process hole and a bare end face 7 facing away from the process hole. The connecting portion 3 is arranged on the bare end face 7 of the sealing plate 1 and extends along the first direction 10. Preferably, the connecting portion 3 is welded to the bare end face 7 of the sealing plate 1. In addition, the first direction 10 is preferably the thickness direction of the sealing plate 1. The pressing portion 4 protrudes from the edge of the sealing plate 1 and can be locked to the connecting portion 3 through the locking portion 5.

[0059] In actual use, when the sealing plate 1 is sealed to the process hole, the pressing part 4 overlaps the edge of the process hole and is connected to the connecting part 3 through the locking part 5, so that the sealing plate 1 is sealed to the process hole in a hanging manner. Further, in the actual installation process, the pressing part 4 is first removed from the sealing part; then the sealing plate 1 is placed in the process hole; and finally, the sealing plate 1 is fixed to the connecting part 3 through the locking part 5, so that the sealing plate 1 is sealed to the process hole in a hanging manner.

[0060] In summary, (1) the present application replaces the existing structural method of welding the mounting plate to the process hole, so there is no need for cutting and welding, and the present application saves installation time; (2) after the sealing test is completed, the structure of the present application can be directly removed without any damage to the parent material (hull plate). (3) The sealing device of the present application can be reused indefinitely, saving materials. In addition, the present application seals the process hole by means of the sealing plate 1, and the press-fitting portion 4 can be used to limit the sealing plate 1 in the first direction 10, thereby preventing the sealing plate 1 from moving in the first direction 10.

[0061] In this embodiment, further, combined with Figure 1 and Figure 2 As shown, the connecting portion 3 is a connecting bolt 11 , the pressing portion 4 is a pressing strip, and the locking portion 5 is a locking nut 13 .

[0062] Specifically, the connecting bolts 11 are fixed to the exposed end surface 7 of the sealing plate 1 by welding and extend along the thickness direction of the sealing plate 1 . Here, the connecting bolts 11 are fixed to the sealing plate 1 by welding, which improves the firmness of the connecting bolts 11 .

[0063] Specifically, a through hole is formed on the press-fitting strip at a position corresponding to the connecting bolt 11 , and the connecting bolt 11 can pass through the press-fitting strip through the through hole.

[0064] In actual use, when the sealing plate 1 is sealed to the process hole, the pressing strip overlaps the edge of the process hole and is connected to the connecting bolt through the locking nut 13, so that the sealing plate 1 is sealed to the process hole in a hanging manner.

[0065] In this embodiment, further, combined with Figure 2As shown, four groups of connecting bolts 11 are provided, and each group of connecting bolts 11 is provided with two connecting bolts 11; four pressing strips are provided, and the four pressing strips are respectively a first pressing strip 14, a second pressing strip 15, a third pressing strip 16 and a fourth pressing strip 17; four groups of locking nuts 13 are provided, and each group of locking nuts 13 is provided with two locking nuts 13.

[0066] Specifically, four groups of connecting bolts 11, four pressing strips and four groups of locking nuts 13 are respectively arranged in one-to-one correspondence.

[0067] Furthermore, the first pressing strip 14 and the second pressing strip 15 are symmetrically arranged about the short semi-axis of the sealing plate 1 and both of the first pressing strip 14 and the second pressing strip 15 form a first preset angle with the short semi-axis; preferably, the first preset angle is 60°.

[0068] Furthermore, the third pressing strip 16 and the fourth pressing strip 17 are symmetrically arranged with respect to the short semi-axis of the sealing plate 1 , and both the third pressing strip 16 and the fourth pressing strip 17 form a first preset angle with the short semi-axis.

[0069] Furthermore, the first pressing strip 14 and the third pressing strip 16 are symmetrically arranged about the long semi-axis of the sealing plate 1 and both of the first pressing strip 14 and the third pressing strip 16 form a second preset angle with the long semi-axis. Preferably, the second preset angle is 60°.

[0070] Furthermore, the second pressing strip 15 and the fourth pressing strip 17 are symmetrically arranged with respect to the long semi-axis of the sealing plate 1 , and both the second pressing strip 15 and the fourth pressing strip 17 form a second preset angle with the long semi-axis.

[0071] In summary, in actual use, both ends of the first press-fitting strip 14, the second press-fitting strip 15, the third press-fitting strip 16 and the fourth press-fitting strip 17 protrude from the edge of the sealing plate 1; therefore, in actual use, the first press-fitting strip 14, the second press-fitting strip 15, the third press-fitting strip 16 and the fourth press-fitting strip 17 are located outside the port of the process hole, and are not located inside the process hole. Therefore, when the first press-fitting strip 14, the second press-fitting strip 15, the third press-fitting strip 16 and the fourth press-fitting strip 17 are locked to the connecting bolt 11 by using the locking nut 13, the sealing plate 1 can be sealed to the process hole in the form of a hanging connection.

[0072] In this embodiment, further, combined with Figure 1 and Figure 2 As shown, in order to improve the more effective sealing of the process hole, the sealing device for sealing test also includes a sealing ring 18.

[0073] Specifically, the sealing ring 18 is arranged on the exposed end surface of the sealing plate 1 and on the circumferential edge of the exposed end surface 7 .

[0074] When the sealing plate 1 is sealed to the process hole, the sealing ring 18 is in close contact with the side wall of the process hole, that is, in this embodiment, the sealing ring 18 is used to effectively and completely seal the process hole, thereby improving the sealing performance.

[0075] In this embodiment, further, in actual combination Figure 1 As shown, in order to prevent the sealing ring 18 from moving in the radial direction and generating a gap, the sealing device for sealing test further includes a reinforcement ring 19 .

[0076] Specifically, the reinforcement ring 19 is arranged on the exposed end surface of the sealing plate 1 and is attached to the inner side wall of the sealing ring 18. That is, the reinforcement ring 19 is used to support the sealing ring 18 to prevent the sealing ring 18 from moving away from the side wall where the process hole is formed when the sealing ring 18 is squeezed with the side wall where the process hole is formed and a gap is generated; in other words, the support ring can support the sealing ring 18 to prevent the sealing ring 18 from deforming in the radial direction.

[0077] In this embodiment, further, combined with Figure 2 As shown, the sealing device for sealing test further includes a handle 20 .

[0078] Specifically, the handle 20 is provided on the exposed end surface of the sealing plate 1. The handle 20 is used to facilitate taking the sealing device.

[0079] In addition, during actual use: (1) a construction worker stands outside the cabin and inserts the sealing device into the process hole, adjusts the position to fit the sealing ring 18 and the side wall with the process hole, and tightens the handle 20; (2) another construction worker embeds the pressing strip into the 8 bolts and uses tools to clamp it tightly; (3) during use, the gas in the cabin flows from the inside to the outside, and the sealing tooling will not pop out and cause safety hazards such as injury. After the test is completed, two people can cooperate to remove the pressing strip.

[0080] In this embodiment, further, combined with Figure 1 As shown, the sealing device for sealing test further includes a reinforcing rib 21 .

[0081] Specifically, the reinforcing rib 21 is disposed on the exposed end surface of the sealing plate 1 .

[0082] Further, three reinforcing ribs 21 are provided; two of the reinforcing ribs 21 extend along the second direction 22, and another reinforcing rib 21 extends along the third direction 23. Figure 1As shown, the second direction 22 refers to the short semi-axis direction of the sealing plate 1, and the third direction 23 refers to the long semi-axis direction of the sealing plate 1. The use of the reinforcing ribs 21 can increase the service life of the sealing plate 1. Therefore, during the sealing test experiment, there will be an extremely high pressure difference. If the strength of the sealing plate 1 is too low, it is very likely to break. The present application just uses the reinforcing ribs 21 to increase the strength of the sealing plate 1, thereby improving the service life of the sealing plate 1 to a certain extent.
