Description

Technical Field

[0001] This utility model relates to the field of modular cable technology, specifically a modular cable penetration sealing fire arrestor. Background Technology

[0002] Cables can be classified into power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of conductors and insulation layers, used to connect circuits or transmit information. In order to improve the safety of cables, fire-resistant structures are installed inside the cables.

[0003] Existing technologies, such as CN215220338U, describe a fire-resistant and flame-retardant cable where the insulation layer and the accommodating space are connected by a first protrusion and a first groove. The accommodating space is also equipped with a heat dissipation pipe. By setting a refractory metal layer and an extruded ceramicized heat insulation layer in the fire-resistant layer, the fire-resistant and flame-retardant effect of the cable is improved, solving the technical problem that the fire-resistant and flame-retardant effect of halogen-free low-smoke fire-resistant cables in the prior art is relatively poor.

[0004] However, this cable still has some shortcomings in its use:

[0005] The cable significantly improves its flame retardant performance by using a fire-resistant metal layer and an extruded ceramic insulation layer. However, this also makes the internal filling of the cable less convenient, especially when additional fire-retardant or sealing materials are required, making the operation more complicated and less efficient.

[0006] The cable's sealing performance also needs improvement. Once the cable is subjected to external pressure or damage, it is prone to leakage, affecting the safe use of the cable. The cable's external protection is low. Utility Model Content

[0007] The purpose of this utility model is to provide a modular cable penetration sealing fire arrestor to solve the problem mentioned in the background art. While the cable has significantly improved its flame retardant performance by using a fire-resistant metal layer and an extruded ceramic insulation layer, this also makes the internal filling of the cable less convenient. In particular, when additional fire arrestor or sealing materials are required, the operation becomes complicated and inefficient. The sealing performance of the cable also needs to be improved. Once the cable is subjected to external pressure or damage, it is easy to cause leakage, which affects the safe use of the cable. The external protection of the cable is low.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A modular cable penetration sealing fire arrestor includes a cable body, a fire arresting component is provided on the side of the cable body, and a protective component is provided on the side of the fire arresting component.

[0010] The fire-arresting assembly includes a fire-arresting module on the side of the cable body. The side of the fire-arresting module is provided with a first mounting block and a second mounting block. The side of the first mounting block is provided with a second mounting groove, and the side of the second mounting block is provided with a first mounting groove. The fire-arresting module is located between the second mounting groove and the first mounting groove. The fire-arresting module is made of EPDM rubber. The second mounting block is rhomboid in shape. The ends of the first mounting block and the second mounting block are respectively provided with metal plates. The side of the metal plates is provided with fixing bolts. The fixing bolts pass through the metal plates and the first mounting blocks and are threadedly connected to the metal plates and the first mounting blocks respectively.

[0011] As a preferred embodiment of this utility model, the protective component includes a shielding layer on the side of the first mounting block, a connecting rib fixedly connected to the outer surface of the shielding layer, an outer protective sleeve provided on the outer surface of the shielding layer, a connecting groove provided on the inner surface wall of the outer protective sleeve, and the connecting rib extending into the connecting groove and fixedly connected to the connecting groove.

[0012] As a preferred embodiment of this utility model, the first mounting block consists of two blocks of the same size and positioned opposite each other, forming a cylindrical shape between the two first mounting blocks. The cable body and the second mounting block are both located inside the cylindrical tube.

[0013] As a preferred embodiment of this utility model, the outer surfaces of both first mounting blocks are fixedly connected to the shielding layer, both first mounting blocks are made of polypropylene, and the second mounting block is made of rubber.

[0014] As a preferred embodiment of this utility model, the material of the shielding layer is synthetic mica tape, and the material of the connecting ribs is synthetic fiber.

[0015] As a preferred embodiment of this utility model, the outer protective sleeve is made of high-density polyethylene, and the outer surface of the outer protective sleeve is coated with an anti-corrosion solution.

[0016] As a preferred embodiment of this utility model, six cable bodies are provided, all six cable bodies are the same size, two first mounting blocks are provided, a second connecting strip is hinged between the two first mounting blocks, and a first connecting strip is hinged between the second mounting block and one of the first mounting blocks.

[0017] As a preferred embodiment of this utility model, the first mounting groove and the second mounting groove are positioned opposite each other, and a cylinder is formed between the first mounting groove and the second mounting groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In this invention, a first mounting block, a second mounting block, a fire-resistant module, and a cable body are used in conjunction. The fire-resistant module is made of EPDM rubber and is designed in layers, allowing for layer-by-layer peeling or addition. If the space between the cable body and the first or second mounting groove is slightly larger or smaller, the inner layers can be peeled off to fit the first or second mounting groove. This material wraps around the outer surface of the cable body layer by layer, allowing for layer-by-layer peeling and diameter changes. The fire-resistant module and the cable body are placed between the first and second mounting blocks, ensuring their stability and reliability. This fire-resistant module solves the problem of insufficient sealing material. At the same time, tightening the fixing bolts will cause the fire-resistant module to expand laterally, thereby compressing the cable body.

[0020] In this invention, by using an external protective sleeve, a shielding layer, connecting ribs, and connecting grooves in combination, the shielding layer is tightly fixed to the external protective sleeve through the connecting ribs, while its inner side is firmly connected to the first mounting block, thereby enhancing the stability of the cable body. The external protective sleeve provides protection for the outside of the cable body, while the shielding layer improves the sealing performance, further enhancing the overall safety. At both ends of the first mounting block, metal plates are respectively configured. These two metal plates are connected by fixing bolts passing through the first mounting block, thereby enhancing the sealing effect. At the same time, the two first mounting blocks and the second mounting block are connected by a hinged design of the first connecting strip and the second connecting strip, allowing the three to be easily connected together.
