Description

Technical Field

[0001] The utility model relates to the technical field of cabin penetration cable sealing, in particular to a cabin penetration cable sealing structure. Background Art

[0002] With the increasing tonnage of ships and the increasing environmental protection requirements, lightweight requirements are widely valued in the world's shipbuilding industry. The lightweight requirements for ship penetration cable seals have been proposed and relevant standards have been formulated.

[0003] Patent CN117254409A discloses a ship cable penetration and sealing structure, which adopts a frameless cable penetration sealing method. There is no need to use a traditional cable frame. It only needs to clamp and fix the penetration support frame at the edge of the cable penetration hole, fill the gap between two adjacent cables and the gap between the outermost cable and the cable penetration hole with filling material, and then use fire-resistant sealant to cover the penetration support frame and the filling material to achieve the sealing of the cable penetration.

[0004] In the patented technical solution, the cabin penetration support frame is composed of a number of cabin penetration support units connected end to end, each of which includes a first clamping portion, two connecting portions extending from the end of the first clamping portion and being centrally symmetrical, and a second clamping portion connected to one of the connecting portions, the second clamping portion is parallel to the first clamping portion, and the connecting portion is perpendicular to the first clamping portion and the second clamping portion. When the cabin penetration support frame is clamped and fixed on the edge of the hole of the cable cabin penetration hole, the connecting portion is respectively located above and below the bulkhead or deck and is perpendicular to the bulkhead or deck.

[0005] In this technical solution, the penetration support frames are densely distributed on the inner side of the bulkhead cavity, and the structure of the penetration support frames is suitable for circular notches. When the notch is a directional notch, the structure of the penetration support frames cannot be densely distributed at the corners of the notch. In addition, the penetration support frames are formed by bending a thinner filamentary structure, which is not very stable and is prone to deformation under stress. The penetration support frames formed by bending a filamentary structure have many pores and poor glue-hanging effect. When using sealant for sealing, the sealing quality between the sealant and the penetration support frames cannot be ensured. Utility Model Content

[0031] Example 1

[0032] See also Figure 1-Figure 7 The present application provides a sealing structure for a cable passing through a cabin, the sealing structure being located inside a notch of a bulkhead 21, the sealing structure comprising a filling layer 23, a sealant 24 and a plurality of clamp assemblies, the clamp assemblies comprising a clamp and a support frame 11; the plurality of clamps are distributed along the inner side wall of the notch, and the opening of the clamp clamps the bulkhead 21 where the notch is located; the support frame 11 is located between the clamp and the bulkhead 21;

[0033] The filling layer 23 is located on one side of the plurality of clamping members close to the center of the gap. The filling layer 23 is provided with an accommodating through hole for the cable to pass through. The sealant 24 wraps the filling layer 23 and the clamp assembly to form a seal for the gap.

[0034] In the present application, the clamping member and the support frame 11 are independently arranged structures, and the structure of the support frame 11 can be designed according to the shape of the gap. When the gap is a square gap, several support frames 11 are surrounded inside the square gap, and when the gap is a circular gap, several support frames 11 are surrounded inside the circular gap. The clamping member can completely cover the support frame 11, or partially cover the support frame 11 to assist in forming a support skeleton of the support frame 11 and the filling layer 23. The clamp assembly of the present application is suitable for gaps of any shape, and the clamping member and the support frame 11 are stable and reliable with good rigidity. With the help of the support frame 11 and the clamping member, the ideal glue hanging effect of the clamp assembly can be ensured, thereby making the entire sealing process smooth, and being able to ensure the sealing firmness between the sealant 24 and the support frame 11, thereby improving the sealing effect and efficiency of the cabin cable 22.

[0035] Example 2

[0036] See also Figure 1-Figure 7The present application provides a sealing structure for a cable passing through a cabin, wherein the sealing structure is located inside a notch in a bulkhead 21, and comprises a filling layer 23, a sealant 24 and a plurality of clamp assemblies, wherein the clamp assembly comprises a clamp and a support frame 11; the plurality of clamps are distributed along the inner wall of the notch, and the opening of the clamp clamps the bulkhead 21 where the notch is located; the support frame 11 is located between the clamp and the bulkhead 21; the filling layer 23 is located on one side of the plurality of clamps close to the center of the notch, and a through hole for the cable to pass through is provided in the filling layer 23, and the sealant 24 wraps the filling layer 23 and the clamp assembly to form a seal for the notch.

[0037] The notch is provided to allow the cabin-penetrating cable 22 to pass through the bulkhead 21, while also ensuring the sealing of the cabin-penetrating cable 22 after passing through the notch. The inner diameter of the notch is much larger than the outer diameter of the cable. In addition to allowing the cable to pass through, it is also necessary to ensure the sealing between the notch and the cabin-penetrating cable 22. The present application collectively refers to the structure formed in the notch as a sealing structure. When forming the sealing structure, it is necessary to first form a sealing skeleton in the notch, and then fill the sealing skeleton with sealant 24 to fill the gap in the sealing skeleton to form a sealing structure. In the present application, the sealing skeleton is mainly formed by a clamp, a support frame 11 and a filling layer 23.

[0038] For example, when the notch is a square hole, several support frames 11 are distributed along the inner diameter of the notch, wherein four support frames 11 can be provided, corresponding to the four sides of the rectangular notch respectively, the length of the support frame 11 corresponds to the field side or short side of the notch, each support frame 11 can clamp multiple clamping members, the opening of the clamping member clamps the bulkhead 21 at the notch, and the support frame 11 is placed between the clamping member and the bulkhead 21. Multiple clamping members can be distributed along the support frame 11, and finally multiple clamping members are arranged side by side on the inner side of the notch.

[0039] A filling layer 23 is placed inside the center of the clamp assembly. The filling layer 23 is provided with an accommodating through hole for the cable to pass through. When forming a sealing structure, the cabin-penetrating cable 22 needs to be placed inside the filling layer 23 to facilitate the formation of subsequent sealant 24 to fill the gap between the cabin-penetrating cable 22 and the filling layer 23.

[0040] The filling layer 23 is a fireproof filling layer with good fireproof performance, ensuring that the sealing structure has good fire resistance and sealing performance.

[0041] Furthermore, the clamping member in the present application includes a bottom plate 13 and two side plates 12, the two side plates 12 are respectively fixed at the top ends of both sides of the bottom plate 13, and the two side plates 12 extend in a direction close to the center of the bottom plate 13, and the two side plates 12 and the bottom plate 13 form a △-shaped clamping member. In the present application, the side of the two side plates 12 away from the bottom plate 13 is the opening direction of the clamping member. When the clamping member does not clamp the support frame 11 or the bulkhead 21, the side of the two side plates 12 away from the bottom plate 13 abuts, that is, the opening is a closed opening at this time. When the clamping member needs to clamp the support frame 11 or the bulkhead 21, the opening of the clamping member is opened to clamp the bulkhead 21, and the support frame 11 is placed between the bulkhead 21 and the side plates 12.

[0042] In the present application, the support frame 11 is an L-frame structure, one end of the support frame 11 is located between the side plate 12 and the bulkhead 21, and the other end is parallel to the bottom plate 13 and extends in a direction away from the bulkhead 21. In other words, the support frame 11 is an L-shaped structure composed of two mutually perpendicular plates, one of which is placed between the side plate 12 and the bulkhead 21, and the other plate extends vertically in a direction away from the bulkhead 21.

[0043] like Figure 4 As shown, when the thickness of the bulkhead 21 is smaller than the length of both ends of the bottom plate 13, since the opening of the side plate 12 away from the bottom plate 13 is smaller, the side plate 12 and the support frame 11 are actually in contact only at the top of the side plate 12. Figure 5 As shown, when the thickness of the bulkhead 21 is equal to the length of the two ends of the bottom plate 13, the side plate 12 and the support frame 11 can achieve surface contact. The length of the two ends of the bottom plate 13 in this application refers to the distance between the two side plates 12 in the bottom plate 13. This size is designed according to the thickness of the bulkhead 21 to ensure that the size is greater than or equal to the thickness of the bulkhead 21.

[0044] As another embodiment, the thickness of the bulkhead 21 may also be greater than the distance between the two side panels 12 in the bottom plate 13. At this time, when the clamping member clamps the bulkhead 21, the opening of the two side panels 12 away from the bottom plate 13 is greater than the distance between the two side panels 12 in the bottom plate 13. At this time, the clamping member does not clamp the support frame 11 and the bulkhead 21 very firmly. The filling layer 23 can be used to abut the clamping member to form a limit on the clamping member and the support frame 11, and the gap can also be sealed.

[0045] Furthermore, in the present application, an ear hole 15 is provided on the outer side of one end of the side panel 12 away from the bottom panel 13, and the ear hole 15 is provided in parallel with the bottom panel 13, and the ear hole 15 is used to accommodate a handle. The ear hole 15 refers to a through hole parallel to the side panel 12 and provided on the outer side of the side panel 12, and the handle is detachably installed in the ear hole 15. When the clamping member does not clamp the bulkhead 21 and the support frame 11, the opening of the side wall is in a closed state, that is, the end of the side wall away from the bottom panel 13 is in an abutment state. At this time, by installing the handle inside the ear hole 15, the opening of the clamping member can be controlled to open, and clamped in the support frame 11 and the bulkhead 21. When the clamping action is completed, the handle can be removed to continue the subsequent sealing process.

[0046] Furthermore, the side plate 12 described in the present application is provided with a first connecting through hole 17, the support frame 11 is provided with a second connecting through hole corresponding to the first connecting through hole 17, and the positioning pin 14 passes through the first connecting through hole 17 and the second connecting through hole in sequence, and abuts against the bulkhead 21. The positioning pin 14 can be specifically a rivet, etc. The present application provides the first connecting through hole 17 and the second connecting through hole, so that gaps can be left between the clamping member and the support member, and between the support member and the bulkhead 21, so as to facilitate the sealant 24 to penetrate into the gap between the clamping member and the support member, and the gap between the support member and the bulkhead 21, thereby ensuring a good sealing effect.

[0047] Similarly, the area of ​​the support frame 11 not covered by the clamping member is provided with a third connecting through hole 18, and the positioning pin 14 passes through the third connecting through hole 18 and abuts against the bulkhead 21. The positioning pin 14 can be specifically a rivet, etc. The third connecting through hole 18 is provided in the present application, so that a gap can be left between the support member and the bulkhead 21, so that the sealant 24 can penetrate into the gap between the support member and the bulkhead 21, thereby ensuring a good sealing effect.

[0048] The support frame 11 described in the present application is provided with a glue hole 16. The glue hole 16 refers to a through hole provided in the two plates of the L-shaped support frame 11. During the curing and sealing process of the sealant 24, the glue hole 16 can allow the sealant 24 to pass through the support frame 11, so that the sealing skeleton structure formed by the support frame 11 and the clamping member forms a complete whole to ensure the sealing effect.

[0049] The side plate 12 and bottom plate 13 of the clamping member in the present application are made of high-strength ultra-thin materials with excellent elasticity and light weight. For example, porous angle steel can be used, which has the advantages of good rigidity, light weight, and convenient glue hanging, ensuring smooth glue coating operation. At the same time, the support frame 11 is made of lightweight materials and is porous, and the overall lightweight requirements are fully met.

[0050] The bulkhead 21 of the gap attachment of the present application can be designed to be serrated to increase the friction between the support frame 11 and the bulkhead 21, so that the clamp assembly can be better hung inside the gap.

[0051] After the sealing frame is formed, the sealing frame is sprayed with glue so that the sealant 24 is hung on the outside of the fixture assembly and the filler and fills the gap inside the sealing frame. It should be noted that the sealant 24 needs to completely cover the gap and the position of the support frame 11 outside the gap during the spraying process. Figure 7 As shown, the outer diameter of the sealant 24 is larger than the outer diameter of the notch, and also needs to be larger than the outer diameter of the support frame 11, and the sealant 24 covers the clamp, the support frame 11 and the filling layer 23, and the sealant 24 fills the gap between the clamp and the support frame 11, the gap between the support frame 11 and the bulkhead 21, the gap between the filling layer 23 and the clamp, and the gap between the clamp and the cable.

[0052] The sealing principle of the sealing structure of a cable penetration in the present application is as follows:

[0053] Clean the surface of the cabin cable 22 and the bulkhead 21;

[0054] Install the handle inside the clip ear hole 15, control the opening of the clamping piece to open, clamp it between the support frame 11 and the bulkhead 21, and remove the handle after the clamping action is completed. Repeat several times, distribute several clamping pieces along the inside of the gap, and the opening of the clamping piece clamps the bulkhead 21 where the gap is located, wherein the support frame 11 is located between the clamping piece and the bulkhead 21. The clamping pieces are distributed in sequence along the inside of the gap, forming the same shape as the gap.

[0055] The cable is passed through the filling layer 23, and the filling layer 23 is placed in the middle of several clamping members; a through hole for the cable to pass through is provided in the filling layer 23, and at the same time, the outer side of the filling layer 23 abuts against the end of the bottom plate 13 in the clamping member away from the side plate 12. At this time, the filling layer 23, the support member and the clamping member form a sealing skeleton.

[0056] The clamping member, the filling layer 23 and the cable are sealed with a sealant 24 to form a sealing structure of the gap. The sealant 24 needs to completely cover the gap and the position of the support frame 11 outside the gap during the spraying process, such as Figure 7 As shown, the outer diameter of the sealant 24 is larger than the outer diameter of the notch, and also needs to be larger than the outer diameter of the support frame 11, and the sealant 24 covers the clamp, the support frame 11 and the filling layer 23, and the sealant 24 fills the gap between the clamp and the support frame 11, the gap between the support frame 11 and the bulkhead 21, the gap between the filling layer 23 and the clamp, and the gap between the clamp and the cable.

[0057] In summary, the clamp assembly in the present application is stable, reliable and has good rigidity. Moreover, the clamp assembly can adapt to cable holes of different wall thicknesses and shapes.

[0058] By providing the glue holes and the first connecting through hole 17 , the second connecting through hole and the third connecting through hole 18 , the sealant 24 is firmly combined with the support frame 11 , and the sealing quality is guaranteed.

[0059] The clamping parts are made of high-strength ultra-thin materials with excellent elasticity and light weight, while the bracket is made of lightweight materials and is porous, and the overall lightweight requirements are fully met. The support frame 11 is made of lightweight materials and is porous, and the overall lightweight requirements are fully met. The glue hanging effect is ideal and the construction is smooth.

[0060] The glue hole 16 allows the sealant 24 to pass through the support frame 11, so that the sealing skeleton structure formed by the support frame 11 and the clamping member forms a complete whole to ensure the sealing effect.

[0061] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
