Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and particularly relates to a fixture and a lightweight cable through-hull sealing structure. Background Technique

[0002] Under the background of the continuous increase in ship tonnage and the continuous improvement of environmental protection requirements, the requirement for lightweight has been widely emphasized in the world shipbuilding industry. The requirement for lightweight of ship through-cable sealing has been put forward, and relevant standards have been formulated.

[0003] Chinese Patent CN117254409A discloses a ship cable through-hull part and a sealing structure, which adopts a frameless cable through-hull part sealing method. There is no need to use a traditional cable frame. Only the through-hull support plate needs to be clamped and fixed at the edge of the hole of the cable through-hull hole. Fill the filling material in the gap between two adjacent cables - the gap between the outermost cable and the cable through-hull hole, and then use the fireproof sealing material to cover the through-hull support plate and the filling material to achieve the sealing of the cable through-hull part. However, in this technical solution, the through-hull support plates are densely distributed on the inner side of the hole in the bulkhead, and the structure of the through-hull support plate is only applicable to circular notches. When the notch is a square notch, the structure of the through-hull support plate cannot be densely distributed at the notch corner. The structure of the through-hull support plate is complex and heavy, and cannot meet the lightweight requirement. Moreover, the through-hull support plate is bent from a relatively thin filamentous structure, with low stability and easy deformation under stress; the through-hull support plate bent from the filamentous structure has more pores and poor rubber coating effect. When using the sealing material for sealing, the sealing quality between the sealing material and the through-hull support plate cannot be ensured.

[0004] Chinese Patent CN118074040A discloses a sealing structure. By filling the support frame between the clamping part of the fixture and the bulkhead, it can be applicable to the sealing of notches with different shapes, and the rubber coating effect of the support plate is better. However, this technical solution still has the following problems: the structure of the fixture is complex, and positioning pins need to be installed to fix the support frame; the contact area between the fixture and the filling layer is small, and it is easy to cause the deformation and bending of the bulkhead under the influence of the gravity of the filling layer. Content of the Utility Model

[0005] In order to overcome the above deficiencies existing in the prior art, the purpose of the utility model is to provide a fixture and a lightweight cable through-hull sealing structure. The utility model can achieve the lightweight of the fixture while ensuring stability and clamping effect by optimizing the fixture structure design. The fixture of the utility model has a simple structure and is easy to operate, and has a wide adaptability with the existing cable through-hull sealing structures, and can be easily integrated into different cable through-hull sealing structures. The support plate of the fixture increases the contact area with the filling layer, and there is no need to use a support frame. Therefore, the fixture of the utility model can reduce the weight of the sealing structure without changing the original sealing effect.

[0006] The object of the present utility model is achieved by at least one of the following technical solutions.

[0007] The first aspect of the present utility model is to provide a fixture, which includes more than two clamping units. Each clamping unit includes a support plate and a clamping plate connected at the end. The inner angle at the connection of the support plate and the clamping plate is an acute angle. Adjacent two clamping units are partially overlapped through the side surface of the support plate. The support plates of adjacent two clamping units are located on the same horizontal plane, and the extending directions of the ends of the support plates of adjacent two clamping units away from the clamping plate are opposite. The extension lines of the projections of the clamping plates of adjacent two clamping units away from the support plate intersect on the projection plane perpendicular to the plane where the support plate is located, and the clamping plates of adjacent two clamping units jointly play a clamping role.

[0008] In the present utility model, a part of the support plate where the clamping plates of adjacent two clamping units are cooperatively overlapped forms a U-shaped opening.

[0009] Preferably, side plates are provided on the clamping plates; and / or, glue holes are provided on the support plates and / or the clamping plates.

[0010] More preferably, the side plates are connected to the ends of the clamping plates away from the support plates; and / or, the inner angle formed at the connection of the clamping plates and the side plates is < 180°.

[0011] Further preferably, the inner angle formed at the connection of the clamping plates and the side plates is < 180°, and on the plane perpendicular to the plane where the support plate is located, the opening directions of the projections of the inner angles formed at the connections of the clamping plates and the side plates of adjacent two clamping units are opposite.

[0012] Preferably, the inner angle at the connection of the support plate and the clamping plate is 80° - 85°; and / or, the length of the support plate is at least 10 mm.

[0013] Preferably, the fixture includes at least 5 clamping units.

[0014] Preferably, the fixture is integrally formed.

[0015] The second aspect of the present utility model is to provide a lightweight cable through-hull sealing structure. The sealing structure is located at the notch of the ship's cabin or deck. The sealing structure includes a filling layer, a sealing material, and several fixtures as described in any one of the above; the fixtures are clamped on the inner side wall of the notch of the ship's cabin or deck, and a filling layer, a sealing material, and a cable are arranged between the fixtures.

[0016] Preferably, the maximum outer diameter of the sealing material is greater than the outer diameter of the notch of the ship's cabin or deck. The sealing material covers the fixtures and the filling layer, and the sealing material fills the gaps between the fixtures and the inner side wall of the notch of the ship's cabin or deck, the gaps between the filling layer and the fixtures, and the gaps between the filling layer and the cable.

[0017] The present utility model also provides a sealing method for a cable passing through a cabin, which adopts the cable passing through cabin sealing structure described in the above technical solution, and includes the following steps:

[0018] (1) Clamp the U-shaped opening of several clamps described in any one of the above on the inner side wall of the cabin or deck notch;

[0019] (2) Pass the cable through the filling layer and place the filling layer between several clamps;

[0020] (3) Wrap and seal the clamps, the filling layer and the cable with a sealing material and fill the gap to form a sealing structure.

[0021] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0022] (1) A clamp with staggered clamping units provided by the present utility model can achieve lightweight while ensuring stability and clamping function through optimizing the clamp structure design. The U-shaped staggered structure of the clamping units of the clamp enables the overall weight of the clamp to be reduced by half compared with the traditional clamp. When applied to the cable passing through cabin sealing structure, the lightweight clamp provided by the present utility model avoids causing additional pressure or deformation to the inner side wall of the cabin or deck notch due to the excessive weight of the clamp. The support plate of the clamp fixes the filling layer, so that the cable passing through cabin sealing structure does not need to use a frame. At the same time, the support plate reduces the pressure of the filling layer on the inner side wall of the cabin or deck notch.

[0023] (2) The clamp of the present utility model can adjust the number of clamping units as needed. Since the clamp has a simple structure and is easy to operate, it has a wide adaptability with the existing cable passing through cabin sealing structures and can be easily integrated into different cable passing through cabin sealing structures.

[0024] (3) The lightweight cable passing through cabin sealing structure provided by the present utility model uses the U-shaped opening of the clamp to clamp the cabin wall, the support plate of the clamp fixes the filling layer, and the space vacated by the clamp is filled with a sealing material, so that the lightweight sealing structure provided by the present utility model is light in weight and does not change the original sealing effect.

[0033] The following further describes the specific implementation of the present utility model in conjunction with examples, but the implementation and protection of the present utility model are not limited thereto.

When an element is referred to as being "on" or "under" another element, the element can be "directly" or "indirectly" located above the other element, or there may also be one or more intermediate elements.

[0036] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems, mechanisms, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0037] In the present utility model, the "U-shaped opening" refers to the opening formed by the support plates that are the parts where the clamping plates of two adjacent clamping units in the fixture are cooperatively lapped. The "side surface of the support plate" refers to the side surface at the end where the support plate is connected to the clamping plate. In the present utility model, the "inner angle at the connection between the support plate and the clamping plate" refers to the included angle between the projection of the support plate and the projection of the clamping plate on a plane perpendicular to the plane where the support plate is located.

[0038] As Figures 1-6 shown, the present utility model provides a fixture 11, which includes two or more clamping units arranged in an interleaved manner. The clamping unit includes a support plate 14 and a clamping plate 13 that are connected at the ends. The inner angle at the connection between the support plate 14 and the clamping plate 13 is an acute angle; two adjacent clamping units are partially lapped through the side surface of the support plate 14 (i.e., the side that is not connected to the clamping plate). The support plates 14 of two adjacent clamping units are located on the same horizontal plane, and the extending directions of the ends of the support plates 14 of two adjacent clamping units away from the clamping plate 13 are opposite; the extension lines of the projections of the two clamping plates of two adjacent clamping units away from the support plate on the projection plane perpendicular to the plane where the support plate 14 is located intersect, and the clamping plates of two adjacent clamping units jointly play a clamping role.

[0039] In any two adjacent clamping units of the present utility model, the two adjacent clamping plates 13 and the partially lapped parts of the two support plates 14 cooperate to jointly form a U-shaped structure. The fixture can adjust the number of clamping units according to needs. The fixture has a simple structure and is easy to operate, and has a wide adaptability with the existing through-cable sealing structure and can be easily integrated into different through-cable sealing structures. By optimizing the structural design of the fixture 11, the present utility model can achieve lightweight while ensuring stability and clamping effect. The interleaved arrangement structure of the clamping units of the fixture 11 can reduce the overall weight of the fixture by half compared with traditional fixtures. In the through-cable sealing structure, the lightweight fixture provided by the present utility model avoids additional pressure or deformation on the inner side wall 21 of the cabin or deck notch caused by the excessive weight of the fixture; and the support plate 14 of the fixture of the present utility model further increases the contact area with the filling layer 23, so that the through-cable sealing structure does not need to use a support frame, and the fixture reduces the pressure of the filling layer 23 on the inner side wall 21 of the cabin or deck notch while reducing its own weight.

[0040] In some preferred embodiments of the present utility model, the fixture 11 is integrally formed, and the overall structure is more stable.

[0041] In some preferred embodiments of the present utility model, in the clamping unit, a side plate 12 is provided on the clamping plate 13 to assist the opening and closing of the clamping plate 13; in a further preferred embodiment, the side plate 12 is connected to one end of the clamping plate 13 away from the support plate 14. When the clamping plate 13 is also connected to the side plate 12, under the action of an external force, the opening and closing of the clamping plate 13 can be controlled through the side plate 12. Preferably, the inner angle formed at the connection between the clamping plate 13 and the side plate 12 < 180° and in a plane perpendicular to the plane where the support plate is located, and the opening directions of the projections of the inner angles formed at the connections between the clamping plates 13 and the side plates 12 of two adjacent clamping units are opposite; further preferably, the inner angle formed at the connection between the clamping plate 13 and the side plate 12 is an obtuse angle, which can be 120°, 135°, 150°, 175°, etc. In a specific embodiment of the present utility model, the clamping plate 13 and the side plate 12 are integrally formed.

[0042] In some preferred embodiments of the present utility model, in order to obtain a more stable clamping force on the side wall of the cabin notch, the fixture 11 includes at least 5 clamping units; the number of clamping units can be an odd number or an even number.

[0043] In a specific embodiment of the present utility model, the fixture 11 is composed of 9 clamping units.

[0044] In some preferred embodiments of the present utility model, the inner angle at the connection between the support plate 14 and the clamping plate 13 is 80° - 85°, which is convenient for the slight opening and closing of the clamping plate 13 to effectively clamp the inner side wall 21 of the cabin or deck notch.

[0045] In some preferred embodiments of the present utility model, the support plate 14 is a flat plate, and its length (i.e., the length from the connection between the support plate and the clamping plate to the other end) should be at least 10 mm, so that the support plate 14 can stably fix the filling layer 23.

[0046] In some preferred embodiments of the present utility model, as Figure 5 shown, glue holes 15 are provided on the support plate 14 so that the sealing material 24 can be poured between the fixture 11 and the inner side wall 21 of the cabin or deck notch to form a firm seal. In some preferred embodiments of the present utility model, glue holes 15 are provided on the clamping plate 13, so that the sealing material 24 can be more easily poured between the fixture 11 and the inner side wall 21 of the cabin or deck notch. Further preferably, glue holes 15 are provided on both the support plate 14 and the clamping plate 13.

[0047] As Figure 7As shown in the figure, the present utility model provides a lightweight cable through-hull sealing structure. The sealing structure is located at the notch of the ship's cabin or deck for the cable to pass through, and is used for frameless sealing of the ship's side cables. The sealing structure includes a filling layer 23, a sealing material 24, and a number of clamps 11. The clamp 11 is clamped on the inner side wall 21 of the notch of the ship's cabin or deck. Between the clamps 11, there are arranged a filling layer 23, a sealing material 24, and a cable through-hull 22.

[0048] The clamp 11 of the present utility model has a U-shaped opening and is clamped on the inner side wall 21 of the notch of the ship's cabin or deck through the U-shaped opening. The support plate 14 of the clamp 11 fixes the filling layer 23, and the gap between two adjacent clamping units of the clamp 11 is filled with the sealing material 24, so that the lightweight sealing structure provided by the present utility model is light in weight and has an enhanced sealing effect.

[0049] As Figure 6 shown in a preferred embodiment, the lightweight cable through-hull sealing structure includes four clamps 11. Each clamp 11 is composed of nine clamping units and is respectively clamped on the inner side wall 21 of the notch of the ship's cabin or deck. The U-shaped opening of the clamp 11 faces the inner side wall. Between the four clamps 11, there are arranged a filling layer 23, a sealing material 24, and a cable through-hull 22.

[0050] In some preferred solutions of the present utility model, the maximum outer diameter of the sealing material 24 is greater than the outer diameter of the notch of the ship's cabin or deck. The sealing material 24 covers outside the clamps 11 and the filling layer 23, and the sealing material 24 fills the gaps between the clamps 11 and the inner side wall 21 of the notch of the ship's cabin or deck, between the filling layer 23 and the clamps 11, and between the filling layer 23 and the cable through-hull 22. In the present utility model, the sealing material 24 directly contacts and seals a part of the cable through-hull 22 (including the cables inside and outside the cabin). The clamps 11, a part of the cable through-hull 22, the filling layer 23, and their gaps are all covered by the sealing material 24, so that the entire sealing structure does not require an additional frame, realizing lightweight frameless sealing.

[0051] The present utility model also provides a method for sealing a cable through-hull, which adopts the lightweight sealing structure described in the above technical solution and includes the following steps:

[0052] [[ID=!7]](1) Clamp the U-shaped openings of a number of clamps 11 on the inner side wall 21 of the notch of the ship's cabin or deck;

[0053] (2) Pass the cable through-hull 22 through the filling layer 23 and place the filling layer 23 among a number of clamps 11;

[0054] (3) Wrap and seal the clamps 11, the filling layer 23, and the cable through-hull 22 with the sealing material 24 and fill the gaps to form a sealing structure.

[0055] The support plate 14 of the fixture 11 according to the present utility model can fix the filling layer 23. Therefore, the cable penetration sealing structure does not need to use a frame. At the same time, the support plate 14 reduces the pressure of the filling layer 23 on the inner side wall 21 of the cabin or deck notch, achieving the effect of further stabilizing and lightening the frameless sealed cable penetration 22.

[0056] The above embodiments are only the preferred embodiments of the present utility model, which are only used to explain the present utility model, rather than limiting the present utility model. Any changes, substitutions, modifications, etc. made by those skilled in the art without departing from the spirit of the present utility model shall fall within the protection scope of the present utility model.
