Description

Technical Field

[0001] The utility model relates to the technical field of cable protection sleeves, in particular to a fireproof and heat-insulating cable protection sleeve for building construction. Background Art

[0002] A cable protective cover is an outer covering used to protect a cable. It is usually made of a specific material and is intended to provide physical protection, waterproofing, moisture resistance, corrosion resistance, insulation, and fire resistance to the cable. Cable protective covers are usually used in the fields of industry, construction, power transmission and distribution, and communications to protect the cable and extend its service life. An existing high-voltage cable protective cover (publication number: CN219227148U) has at least the following defects in use:

[0003] 1. Cables may be affected by external high temperature sources during operation. If the cable protective cover is not fireproof, once it comes into contact with the fire source, it is easy to cause the fire to spread and expand, increasing the risk of fire. When a fire occurs, the cable protective cover cannot effectively resist the flame and high temperature, and the cable itself is easily damaged, causing a short circuit or open circuit, affecting normal use and safe operation. Therefore, a fireproof cable protective cover for construction is needed.

[0004] 2. In a high temperature environment, if the cable protective cover cannot effectively insulate, it may cause the temperature inside the cable to rise, affect the normal working performance of the cable, and even accelerate the aging of the cable and shorten the service life of the cable. Therefore, a heat-insulating cable protective cover for construction is needed.

[0005] 3. When cable laying, replacement or repair is required, if the cable protective cover is not convenient to install and remove, it will increase the difficulty and complexity of construction and repair. Additional time and human resources may be required to complete these tasks. In the process of removing the cable protective cover, if the operation is careless or the tool is inappropriate, it may cause damage to the cable itself or the surrounding equipment and components, increasing the cost of repair and replacement. Therefore, a cable protective cover that is easy to install and remove for construction is needed. Utility Model Content

[0026] A fireproof and heat-insulating cable protective cover for construction includes a protective shell 1, wherein the protective shell 1 includes an upper protective shell 101 and a lower protective shell 102, and a protective shell fixing plate 2 and a protective shell connecting plate 3 are installed on the upper protective shell 101 and the lower protective shell 102. An insulation layer 5 is provided inside the protective shell 1, and the insulation layer 5 is divided into an upper insulation layer 501 and a lower insulation layer 502.

[0027] Specifically: the protective shell fixing plate 2 fixes the upper protective shell 101 and the lower protective shell 102 through bolts 4 .

[0028] Specifically: the protective shell connecting plate 3 is fixed to the adjacent protective shells 1 by bolts 4 .

[0029] Specifically: the protective shell 1 is made of a vacuum insulation panel.

[0030] Specifically: the thermal insulation layer 5 is made of thermal insulation and fireproof cotton.

[0031] Specifically: the thermal insulation layer 5 and the protective shell 1 are bonded together by glue.

[0032] In this embodiment, the protective shell 1 includes an upper protective shell 101 and a lower protective shell 102, and the protective shell 1 adopts a vacuum insulation panel. The vacuum insulation panel adopts the STP vacuum insulation panel produced by Langfang Yuanmei Insulation Engineering Co., Ltd. This product is made of inorganic materials, has no irritation, and meets the fire protection standards. The inorganic fiber core material and the high gas barrier composite film are used as constituent materials, which can effectively play a fire protection function and resist aging for more than 50 years. The interior of the vacuum insulation panel is filled with a rarefied gas or vacuum, which reduces gas heat conduction and convection heat transfer, thereby effectively isolating the influence of the external high temperature environment on the cable and providing excellent thermal insulation effect. The vacuum insulation panel has good fire resistance under high temperature conditions, can effectively prevent flames, heat radiation and smoke from invading the cable, and improve the fire resistance of the cable system. The fireproof cable protective cover for construction using vacuum insulation panels has higher safety and reliability, can effectively reduce the risk of fire, and protect the safety of the cable system and surrounding equipment.

[0033] In this embodiment, a thermal insulation layer 5 is provided inside the protective shell 1, and the thermal insulation layer 5 is divided into an upper thermal insulation layer 501 and a lower thermal insulation layer 502. The thermal insulation layer 5 uses thermal insulation and fireproof cotton. The thermal insulation and fireproof cotton has high thermal insulation performance, can effectively isolate the influence of the external high temperature environment on the cable, reduce heat conduction, and provide good thermal insulation effect. The thermal insulation and fireproof cotton has good fire resistance, can effectively isolate and prevent the spread of flames, improve the fire resistance of the cable system, and reduce the risk of fire. The thermal insulation and fireproof cotton material is soft, easy to install and fix inside the protective shell 1, and also convenient for maintenance and replacement.

[0034] In this embodiment, a protective shell fixing plate 2 and a protective shell connecting plate 3 are installed on the upper protective shell 101 and the lower protective shell 102. The protective shell fixing plate 2 fixes the upper protective shell 101 and the lower protective shell 102 through bolts 4, and the protective shell connecting plate 3 fixes the adjacent protective shells 1 through bolts 4.

[0035] Due to the design of fixing with bolts 4, the operation can be completed by simply installing or removing bolts 4 during disassembly and assembly, making the maintenance, replacement and repair of the cable protective cover very fast and convenient. Its convenient disassembly and assembly design can reduce the working time and labor intensity of maintenance personnel, thereby reducing maintenance costs and improving maintenance efficiency. The bolt 4 design of the fixing plate and the connecting plate of the protective shell 1 makes the assembly structure of the cable protective cover more flexible, and can be quickly adjusted and changed as needed to meet the requirements of different scenarios. The design of fixing with bolts 4 makes the installation process simpler and more intuitive, without the need for complex tools and techniques, and can be quickly installed even on site. Due to the convenient disassembly and assembly, maintenance and replacement are faster and more effective, which can reduce production losses caused by downtime due to failures and improve work efficiency and production continuity.

[0036] It should be noted that the utility model is a fireproof and heat-insulating cable protective cover for construction. By adopting a protective shell 1 made of a vacuum insulation board, it can effectively prevent flames, heat radiation and smoke from invading the cable, thereby improving the fire resistance of the cable system; by adopting a thermal insulation layer 5, it can effectively isolate the influence of the external high temperature environment on the cable, reduce heat conduction, and provide a good thermal insulation effect; by adopting bolts 4, it can be easily disassembled and assembled, reducing the working time and labor intensity of maintenance personnel, thereby reducing maintenance costs and improving maintenance efficiency.
