Description

Technical Field

[0001] This utility model belongs to the field of cable technology and relates to a high-sealing waterproof power cable. Background Technology

[0002] Fire-resistant cables are cables that can maintain safe operation for a certain period of time under flame combustion conditions. They are widely used in high-rise buildings, subways, underground streets, large power plants, and important industrial and mining enterprises—places related to fire safety and fire rescue. Examples include power supply and control lines for fire-fighting equipment and emergency lighting. Power cables are widely used in production and daily life, primarily in the power, metallurgy, petroleum, chemical, and construction industries. Existing cables rely on a single external waterproof layer; however, over long-term use, wear and aging can occur, leading to damage and breaches in the external waterproof layer. This damage can then corrode the internal conductors, causing short circuits and overall cable malfunction. Therefore, a highly sealed, waterproof power cable is proposed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a highly sealed and waterproof power cable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-sealing waterproof power cable includes an irregularly shaped conductor, an outer wrapping layer, an outer insulating layer, an inner shielding layer, an inner waterproof sheath, and a filling layer. The filling layer is further encased in an outer shielding layer, a buffer padding layer, a fireproof layer, and an outer protective sleeve, which is placed inside the outer waterproof sheath.

[0006] In the aforementioned high-sealing waterproof power cable, the irregularly shaped conductor is divided into multiple parts, and the multiple individual irregularly shaped conductors are pressed together as one piece. The irregularly shaped conductor is covered with a fixed connection wrapping layer, and the inner wall of the wrapping layer is tightly attached to the outer wall of the multiple individual irregularly shaped conductors.

[0007] In the aforementioned high-sealing waterproof power cable, a fixed-connection insulation layer is sleeved outside the wrapping layer, and a fixed-connection inner shielding layer is sleeved outside the insulation layer. The inner shielding layer, insulation layer, wrapping layer, and irregularly shaped conductor are integrated.

[0008] In the aforementioned high-sealing waterproof power cable, the inner waterproof sheath has multiple covering parts, and there is a gap between the multiple covering parts. At the same time, the multiple covering parts equally divide the inner waterproof sheath.

[0009] In the aforementioned high-sealing waterproof power cable, an inner shielding layer is inserted and fixedly connected inside the sheath, and the inner shielding layer and the inner waterproof sleeve are integrated.

[0010] In the aforementioned high-sealing waterproof power cable, the filling layer is provided with a placement part, and a fixed connection inner waterproof sleeve is inserted into the placement part. At the same time, the inner wall of the placement part is tightly fitted with the outer wall of the inner waterproof sleeve.

[0011] In the aforementioned high-sealing waterproof power cable, a fixed outer shielding layer is fitted outside the filling layer, and a fixed inner buffer padding layer is fitted outside the outer shielding layer.

[0012] In the aforementioned high-sealing waterproof power cable, a fireproof layer is fixedly connected to the outer layer of the buffer inner pad.

[0013] In the aforementioned high-sealing waterproof power cable, a sliding connection outer protective sleeve is provided outside the fireproof layer.

[0014] In the aforementioned high-sealing waterproof power cable, the outer protective sleeve is fitted with a fixed-connection outer waterproof rubber sleeve.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] This utility model features an externally wound wrapping layer on the irregularly shaped conductor, an insulating layer outside the wrapping layer, an inner shielding layer outside the insulating layer, an inner waterproof sleeve outside the inner shielding layer, a filling layer outside the inner waterproof sleeve, an outer shielding layer outside the filling layer, a buffer pad outside the outer shielding layer, a fireproof layer outside the buffer pad, an outer protective sleeve outside the fireproof layer, and an outer waterproof sleeve outside the outer protective sleeve. By integrating the wrapping layer, insulating layer, and inner shielding layer onto the irregularly shaped conductor, and using the inner waterproof sleeve for internal protection, with the inner waterproof sleeve inserted into the filling layer, and the outer protective sleeve and outer waterproof sleeve at the outermost edge of the filling layer, the cable's waterproofness is ensured. Therefore, even if the outermost outer sheath or outer waterproof sleeve cracks, it will not affect the overall use of the cable. This double-layer waterproof design significantly enhances its waterproof performance.

[0017] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a high-sealing waterproof power cable includes a shaped conductor 1, an outer wrapping layer 2, an outer insulation layer 3, an inner shielding layer 4, an inner waterproof sleeve 5, which is placed inside a filling layer 6, an outer shielding layer 7, an outer buffer padding layer 8, a fireproof layer 9, and an outer protective sleeve 10, which is placed inside an outer waterproof sleeve 11.

[0026] The irregular conductor 1 is divided into multiple parts, and the multiple individual irregular conductors 1 are pressed together into one piece. The irregular conductor 1 is covered with a fixed connection wrapping layer 2, and the inner wall of the wrapping layer 2 is tightly attached to the outer wall of the multiple individual irregular conductors 1.

[0027] After multiple irregularly shaped conductors 1 are combined into one, a wrapping layer 2 is wound around the outside, so that the wrapping layer 2 firmly and tightly presses the multiple irregularly shaped conductors 1 together, so that they can maintain common output during operation.

[0028] Furthermore, an insulating layer 3 is fixedly connected to the outside of the wrapping layer 2, and an inner shielding layer 4 is fixedly connected to the outside of the insulating layer 3. The inner shielding layer 4, the insulating layer 3, the wrapping layer 2 and the irregular conductor 1 are integrated.

[0029] The inner shielding layer 4 provided outside the irregular conductor 1 is for signal protection of the irregular conductor 1 and to prevent external interference.

[0030] Furthermore, the inner waterproof sleeve 5 has multiple covering parts 501, and there is a gap between the multiple covering parts 501. At the same time, the multiple covering parts 501 equally divide the inner waterproof sleeve 5.

[0031] After the outer side of the wrapping layer 2 is provided with an insulating layer 3 and an inner shielding layer 4, the multiple structures in the inner shielding layer 4 are integrated into a whole. In this way, during use, the whole formed by the multiple irregular conductors 1 and the inner shielding layer 4 is easier to transmit and also protects the multiple irregular conductors 1. At the same time, after the inner waterproof sleeve 5 is put on the outside of this whole, the inner waterproof sleeve 5 is used to provide internal waterproof protection for the transmission whole.

[0032] The inner shielding layer 4 is inserted and fixedly connected within the covering part 501, and the inner shielding layer 4 and the inner waterproof sleeve 5 are integrated.

[0033] Furthermore, the filling layer 6 is provided with a placement part 601, and the inner waterproof sleeve 5 is inserted and fixedly connected into the placement part 601. At the same time, the inner wall of the placement part 601 is tightly fitted with the outer wall of the inner waterproof sleeve 5.

[0034] The multiple irregularly shaped conductors 1 and the outer inner waterproof sleeve 5 formed by the filling layer 6 are wrapped by the filling layer 6. In this way, the filling layer 6 has such an integral structure to form a complete transmission cable, and the filling layer 6 provides a layer of protection for such an integral structure.

[0035] Furthermore, an outer shielding layer 7 is fixedly connected to the outside of the filling layer 6, and a buffer inner padding layer 8 is fixedly connected to the outside of the outer shielding layer 7.

[0036] The outer shielding layer 7 provided outside the filling layer 6 covers the entire structure of the multiple irregular conductors 1 inside, and performs a shielding treatment using the outer shielding layer 7.

[0037] Furthermore, a fireproof layer 9 is fixedly connected to the outside of the inner cushioning layer 8.

[0038] The fireproof layer 9 provided outside the buffer inner pad 8 provides fire protection for the buffer inner pad 8 and its internal structure, making the entire cable resistant to high temperatures.

[0039] Furthermore, a sliding protective sleeve 10 is fitted over the fireproof layer 9.

[0040] Furthermore, an outer waterproof sleeve 11 is provided on the outer protective sleeve 10 for fixed connection.

[0041] An outer protective sleeve 10 and an outer waterproof rubber sleeve 11 are fitted over the outer cushioning inner pad 8, and the outer protective sleeve 10 and the outer waterproof rubber sleeve 11 are integrated. The outer waterproof rubber sleeve 11 provides the first layer of waterproofing for the entire structure, while the outer protective sleeve 10 reduces external wear.

[0042] Working principle:

[0043] A wrapping layer 2 is provided on the outside of the irregularly shaped conductor 1, and the irregularly shaped conductor 1 is composed of multiple individual irregularly shaped conductors 1. The wrapping layer 2 is used to wrap and press the conductors together to form a single, integrated transmission wire. An insulation layer 3 is provided outside the wrapping layer 2, and an inner shielding layer 4 is provided outside the insulation layer 3. Thus, the irregularly shaped conductor 1, the wrapping layer 2, the insulation layer 3, and the inner shielding layer 4 form a single unit. The insulation layer 3 covers the irregularly shaped conductor 1, preventing leakage between them internally. The inner shielding layer 4 prevents external interference to the irregularly shaped conductor 1. The entire unit, consisting of the irregularly shaped conductor 1, the wrapping layer 2, the insulation layer 3, and the inner shielding layer 4, is inserted into an inner waterproof sleeve 5. The inner waterproof sleeve 5 protects and secures this unit. The sleeve 5, together with the irregularly shaped conductor 1, is inserted into the filling layer 6. The filling layer 6 is used to fix and protect this whole assembly and the inner waterproof sleeve 5. An outer shielding layer 7 is provided outside the filling layer 6. In this way, the outer shielding layer 7 provides the same shielding for multiple such whole assemblies inside, preventing interference of the entire cable. A buffer pad 8 is provided outside the outer shielding layer 7, and a fireproof layer 9 is provided outside the buffer pad 8. At the same time, the fireproof layer 9 provides fire protection for the entire cable. An outer protective sleeve 10 is provided outside the fireproof layer 9, and an outer waterproof sleeve 11 is provided outside the outer protective sleeve 10. The outer protective sleeve 10 and the outer waterproof sleeve 11 form an integral whole, which is the outermost layer of the cable. After covering, it forms the integrity of the cable and provides protection and external waterproofing for the cable.
