Description

Technical Field

[0001] The present application relates to the field of building lightning protection and fire protection, and in particular to a lightning protection device applied to a structure. Background Art

[0002] Lightning rods are a common structure for building lightning protection. They are effective and can effectively reduce the harm caused by lightning. Lightning rods are often equipped with conductive columns and grounding wires, which can guide the lightning on the lightning rod to the ground.

[0003] The conductive column is usually a metal column, which is set on or inside the wall of the building. When the conductive column is set outside the wall, it is usually wrapped with a foam insulation layer and insulated, and then fixed to the wall by a clamp or a clamp.

[0004] However, some buildings are smaller and the conductive columns are thinner. When the lightning rod is protecting against lightning, it will generate current in the local area of ​​the conductive column connected by the clamp or the hoop, which will break down the insulation layer and ignite the foam, causing local fire. At this time, there is not only the risk of fire, but also the risk of leakage. Summary of the invention

[0005] The present application provides a lightning protection device applied to a structure, which is used to solve the problem of fire or leakage at the connection of conductive poles.

[0006] The present application provides a lightning protection device applied to a structure, comprising a conductive column, an insulating medium, a protective sleeve, a mounting piece, a metal sleeve and a fireproof layer; the insulating medium is arranged outside the conductive column and wraps the conductive column; the protective sleeve is arranged outside the insulating medium and wraps the insulating medium; the mounting piece is arranged outside the protective sleeve, and the mounting piece is connected to a preset wall; the metal sleeve is arranged between the protective sleeve and the insulating medium, and the metal sleeve wraps the protective sleeve in the axial direction of the conductive column; the fireproof layer is arranged outside the metal sleeve and is fixedly connected to the metal sleeve.

[0007] The conductive column, insulating medium, protective cover and mounting parts in the present application can play a conventional protective, diversion and fixing role. When lightning is attracted, lightning may partially break through the insulating medium and cause local fire on the protective cover. The metal cover can provide protection for the conductive column at the connection to avoid excessive deformation or cracking of the insulating medium or the protective cover when the mounting parts are connected, and at the same time prevent lightning from breaking through the protective cover. On the other hand, the fireproof layer can prevent lightning from breaking through or penetrating the insulating medium, causing the metal cover to be electrified and catch fire, thereby providing a safety protection effect for the conductive column.

[0008] In some embodiments of the present application, the metal sleeve is aluminum metal, and the metal sleeve is arranged outside the insulating medium; the metal sleeve and the insulating medium are tightly connected. Aluminum metal has good ductility, which is helpful for the processing and manufacturing of the conductive column, and at the same time, it has low cost, good anti-corrosion effect, and is safe and durable.

The plurality of mounting members can better fix the conductive column on the preset wall, and the connection between the conductive column and the preset wall is stable. The metal sleeves are arranged one by one with the mounting members, and can protect the installation location of each conductive column.

[0010] In some embodiments of the present application, a plurality of metal sleeves are distributed at equal intervals, which can provide a more stable protection effect on the conductive column.

[0011] In some embodiments of the present application, the metal sleeve and the fireproof layer are arranged in multiple layers, and the multiple layers of metal sleeves and the multiple layers of fireproof layers are arranged between the protective sleeve and the insulating medium; the metal sleeve and the fireproof layer are arranged alternately.

[0013] In some embodiments of the present application, the conductive column includes an inner conductor, an outer conductor and a filling medium, the outer conductor is a ring structure, the inner conductor is arranged inside the outer conductor, a gap is formed between the inner conductor and the outer conductor, and the filling medium is arranged between the inner conductor and the outer conductor. The conductive column atmosphere inner conductor and outer conductor can make the conductive column have a better conductive effect.

[0014] In some embodiments of the present application, along the cross section of the conductive column, the coverage area of ​​the filling medium is larger than the cross-sectional area of ​​the inner conductor, and the coverage area of ​​the filling medium is larger than the cross-sectional area of ​​the outer conductor. The large cross-sectional area of ​​the filling medium can stabilize the spacing between the inner conductor and the outer conductor, and can make the spacing larger, thereby avoiding convection or other dangerous circuit phenomena between the inner conductor and the outer conductor.

[0025] Lightning rods are a common structure for building lightning protection. They are effective and can effectively reduce the harm caused by lightning. Lightning rods are often equipped with conductive columns and grounding wires, which can guide the lightning on the lightning rod to the ground.

[0026] The conductive column is usually a metal column, which is set on or inside the wall of the building. When the conductive column is set outside the wall, it is usually wrapped with a foam insulation layer and insulated, and then fixed to the wall by a clamp or a clamp.

[0027] However, some buildings are smaller and the conductive columns are thinner. When the lightning rod is protecting against lightning, it will generate current in the local area of ​​the conductive column connected by the clamp or the hoop, which will break down the insulation layer and ignite the foam, causing local fire. At this time, there is not only the risk of fire, but also the risk of leakage.

[0028] To do this, please refer to Figure 1 The present application provides a lightning protection device for a structure, comprising a conductive column 1, an insulating medium 2, a protective cover 3, a mounting member 4, a metal cover 5 and a fireproof layer 6.

[0029] Please refer to Figure 1 , the insulating medium 2 is arranged outside the conductive column 1 and wraps the conductive column 1. The conductive column 1 can be a metal column, preferably made of copper, and the insulating medium 2 can be a plastic layer, that is, a plastic wrapping layer commonly used outside the wire.

[0030] Please refer to Figure 1 The protective cover 3 is arranged outside the insulating medium 2 and wraps the insulating medium 2; the mounting member 4 is arranged outside the protective cover 3, and the mounting member 4 is connected to the preset wall. The protective cover 3 and the mounting member 4 are both conventional structures. The protective cover 3 is usually made of foam material and is directly wrapped on the conductive column 1. The mounting member 4 can be a clamp or a U-shaped metal frame, which can achieve a similar installation effect as the clamp.

[0031] Please refer to Figure 1 The metal sleeve 5 is arranged between the protective sleeve 3 and the insulating medium 2, and the metal sleeve 5 wraps the protective sleeve 3 in the axial direction of the conductive column 1. The metal sleeve 5 can be arranged outside the insulating medium 2, and has a good fixing and protection effect on the insulating medium 2, so as to avoid the insulating medium 2 being damaged during installation and use, which makes it easier for lightning to leak.

[0032] Please refer to Figure 1 The fireproof layer 6 is arranged outside the metal sleeve and is fixedly connected to the metal sleeve. The fireproof layer 6 can be a tin foil layer, so that the outer protective sleeve 3 is protected by the ability of the tin foil not to catch fire.

[0033] Please refer to Figure 1The conductive column 1, insulating medium 2, protective cover 3 and mounting member 4 in the present application can play a conventional role of protection, drainage and fixation. When lightning is attracted, lightning may partially break through the insulating medium 2 and cause local fire on the protective cover 3. The metal cover 5 can provide protection for the conductive column 1 at the connection to avoid excessive deformation or cracking of the insulating medium 2 or the protective cover 3 when the mounting member 4 is connected, and at the same time, it can prevent lightning from breaking through the protective cover 3. On the other hand, the fireproof layer 6 can prevent lightning from breaking through or penetrating the insulating medium 2, causing the metal cover 5 to be electrified and ignited, thereby providing a safety protection effect for the conductive column 1.

[0034] Please refer to Figure 1 In some examples, the metal sleeve 5 is aluminum metal, and the metal sleeve 5 is sleeved outside the insulating medium 2; the metal sleeve 5 and the insulating medium 2 are tightly connected. Aluminum metal has good ductility, which is helpful for the processing and manufacturing of the conductive column 1, and at the same time, it has low cost, good anti-corrosion effect, and is safe and durable.

[0035] In some examples, the thickness of the metal sleeve 5 may be between 1 mm and 3 mm, and only needs to provide a protective effect.

[0036] In some examples, the metal sleeve 5 and the insulating medium 2 can be tightly connected. The tight connection can be understood as the inner diameter of the metal sleeve 5 is smaller than the outer diameter of the insulating medium 2, so that the metal sleeve 5 can be installed on the insulating medium 2 through the deformation of the insulating medium 2, and the two are relatively fixed.

[0037] Please refer to Figure 1 In some examples, a plurality of mounting members 4 are provided, and the plurality of mounting members 4 are arranged at intervals on the conductive column 1; a plurality of metal sleeves 5 are provided, and the plurality of metal sleeves 5 correspond to the plurality of mounting members 4 one by one, and the metal sleeves 5 are arranged at the mounting members 4. The plurality of mounting members 4 can better fix the conductive column 1 on the preset wall, and the connection between the conductive column 1 and the preset wall is stable. The metal sleeves 5 are arranged one by one with the mounting members 4, and can protect the installation location of each conductive column 1.

[0038] Please refer to Figure 1 In some examples, the preset wall is a wall on which a lightning rod is installed. In order to ensure the stable installation of the conductive column 1, the number of the mounting parts 4 can be set according to the height of the preset wall.

[0039] In some examples, the mounting member 4 can be disposed in the middle of the metal sleeve 5 or in other positions. The desired protection effect can be achieved by simply disposing the mounting member 4 outside the metal sleeve 5 .

[0040] In some examples, the plurality of metal sleeves 5 are distributed at equal intervals. The equal interval distribution can make the protective effect of the conductive column 1 more stable.

[0041] In some examples, the equidistant distribution can be understood as equal spacing along the axis direction of the conductive pillar 1 , or can also be understood as equal spacing along the height direction.

[0042] Please refer to Figure 2 In some examples, the metal sleeve 5 and the fireproof layer 6 are arranged in multiple layers, and the multiple layers of the metal sleeve 5 and the multiple layers of the fireproof layer 6 are arranged between the protective sleeve 3 and the insulating medium 2; the metal sleeve 5 and the fireproof layer 6 are arranged alternately. The multiple layers of the metal sleeve 5 and the fireproof layer 6 can provide a better protective effect on the conductive column 1.

[0043] Please refer to Figure 2 In some examples, the metal sleeve 5 is provided with two layers, and the fireproof layer 6 is provided with two layers. The two layers of metal sleeve 5 and the two layers of fireproof layer 6 can play a good protective effect.

[0044] In some other examples, the metal sleeve 5 can also be set to three layers, and the fireproof layer 6 can be set to two layers, which can also meet the usage requirements.

[0045] The number of layers of the metal sleeve 5 and the fireproof layer 6 can be equal or unequal, and they only need to be arranged alternately.

[0046] Please refer to Figure 1 In some examples, the conductive column 1 includes an inner conductor 11, an outer conductor 12 and a filling medium 13, the outer conductor 12 is a ring structure, the inner conductor 11 is arranged in the outer conductor 12, a gap is formed between the inner conductor 11 and the outer conductor 12, and the filling medium 13 is arranged between the inner conductor 11 and the outer conductor 12. The conductive column 1 includes the inner conductor 11 and the outer conductor 12 to make the conductive effect of the conductive column 1 better.

[0047] Please refer to Figure 1 The inner conductor 11, the outer conductor 12 and the filling medium 13 are the conventional structures of the conductive column 1. By increasing the surface of the conductive column 1, lightning is transmitted faster according to the skin effect, thereby improving the conductive effect.

[0048] The filling medium 13 may be a fleece layer, or may be foam or plastic.

[0049] Please refer to Figure 1 In some examples, along the cross section of the conductive pillar 1, the coverage area of ​​the filling medium 13 is larger than the cross-sectional area of ​​the inner conductor 11, and the coverage area of ​​the filling medium 13 is larger than the cross-sectional area of ​​the outer conductor 12. The large cross-sectional area of ​​the filling medium 13 can stabilize the spacing between the inner conductor 11 and the outer conductor 12, and can make the spacing larger, thereby avoiding convection or other dangerous circuit phenomena between the inner conductor 11 and the outer conductor 12.

[0050] In some examples, the lightning protection device applied to the structure further includes a lightning rod and a grounding wire, wherein the lightning rod is electrically connected to one end of the conductive column 1, and the grounding wire is electrically connected to the other end of the conductive column 1. The lightning rod and the grounding wire can complete the work of attracting lightning together with the conductive column 1.

[0051] Lightning rods and grounding wires are both conventional structures and will not be described in detail here.

[0052] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
