Description

Technical Field

[0001] This utility model relates to the field of protective pipes, and more specifically, to a lightweight and pressure-resistant structure for a portable cable protective pipe. Background Technology

[0002] Cables are used to transmit power, signals, or data, and are widely used in various fields such as industry, communications, construction, and energy. With the continuous growth of demand for power, communications, and energy, underground cable laying has become an important solution. Underground cable laying can effectively avoid damage to cables from the external environment. Cable protection pipes are usually used to protect cables from mechanical damage, external environmental influences, temperature changes, chemical corrosion, and other threats. However, existing cable protection pipes still have the following shortcomings:

[0003] Traditional cable protection pipes are prone to deformation, cracking, or collapse under soil pressure or external loads during use, which can affect the cable's protective effect and may lead to short circuits or damage, causing power outages or communication interruptions. Therefore, a lightweight cable protection pipe with a weight-reducing and pressure-resistant structure is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the problem that traditional cable protection pipes deform, crack, or collapse under soil pressure or external loads during use, which affects the protection effect of cables and may also lead to short circuits or damage to cables, causing power outages or communication interruptions.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0023] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] like Figure 4 As shown, this embodiment proposes a lightweight cable protection pipe with a weight-reducing and pressure-resistant structure, including an outer pipe 1 and an inner pipe 2. A reinforcing component 3 is provided on the outside of the outer pipe 1 to improve the pressure resistance of the protection pipe. A buffer layer 4 is provided between the outer pipe 1 and the inner pipe 2 to improve the protective performance of the protection pipe. In use, the outer pipe 1 directly bears the mechanical load of the external environment, the reinforcing component 3 can effectively disperse stress and prevent pipe deformation or rupture, the inner pipe 2 is in direct contact with the cable, protecting the cable from external environmental corrosion, and the buffer layer 4 can effectively absorb and disperse impact energy.

[0027] like Figure 2 As shown, the reinforcing component 3 includes annular reinforcing ribs 301 and strip reinforcing ribs 302 fixedly connected to the outer pipe 1. The annular reinforcing ribs 301 are evenly distributed along the axial direction of the outer pipe 1, and there are several annular reinforcing ribs 301, which are evenly distributed along the length direction of the outer pipe 1 to enhance axial compressive strength. There are several strip reinforcing ribs 302, which are circumferentially distributed along the central axis of the outer pipe 1 to improve circumferential strength. In use, the annular reinforcing ribs 301 can ensure that the pipeline remains stable under axial pressure, and the strip reinforcing ribs 302 can enhance the pipeline's resistance to torsion and bending.

[0028] As shown in the figure, several weight-reducing grooves 5 are formed on the inner wall of the inner pipe 2, and they are evenly distributed along the central axis of the inner pipe 2. The weight-reducing grooves 5 can reduce the amount of material used and reduce the overall weight of the protective pipe. In use, the weight-reducing grooves 5 effectively reduce the weight of the protective pipe. The weight-reducing grooves 5, which are evenly distributed on the inner wall of the inner pipe 2, ensure the weight reduction of the pipe while maintaining the structural strength of the protective pipe.

[0029] like Figure 4 As shown, the outer tube 1 is made of glass fiber reinforced polypropylene with a thickness of 2-3 mm. Glass fiber reinforced polypropylene has high strength, rigidity, corrosion resistance, and high temperature resistance. The addition of glass fiber also improves the tensile strength and impact resistance of the outer tube 1. The inner tube 2 is made of high-density polyethylene with a thickness of 3-4 mm. High-density polyethylene has excellent corrosion resistance, aging resistance, impact resistance, and mechanical strength. Its smooth inner wall and low coefficient of friction facilitate cable insertion and extraction. During use, the outer tube 1 effectively resists external pressure, preventing pipe deformation or rupture, while the inner tube 2 directly contacts the cable, providing a smooth passage to reduce cable wear.

[0030] like Figure 4 As shown, the buffer layer 4 is made of ABS plastic, which has good impact strength and pressure resistance. The buffer layer 4 has a honeycomb structure and a thickness of 2-3 mm. The honeycomb structure gives it excellent buffering performance and can effectively absorb and disperse impact energy. In use, when the pipeline is subjected to external impact or vibration, the honeycomb structure of the ABS plastic can absorb and disperse energy, reduce the impact on the inner pipe 2 and the cable, and improve the overall protection performance.

[0031] like Figure 1 As shown, the outer surface of the outer tube 1 is coated with an anti-corrosion coating made of epoxy resin paint. During use, the epoxy resin paint forms a dense protective film, preventing corrosive substances in the soil from corroding the outer tube 1, thereby extending the service life of the protective tube.

[0032] like Figure 1 As shown, flanges 6 are provided at both ends of the outer pipe 1, and the flanges 6 are heat-fused to the outer pipe 1. In use, the flanges 6 are tightly connected to the flanges 6 of other pipes or equipment by bolts to form a sealed channel, ensuring the continuous transmission of cables in the protective pipe and facilitating the installation and maintenance of the protective pipe. The heat-fusion connection allows for a tighter connection between the flanges 6 and the outer pipe 1.

[0033] Specifically, the weight-reducing and pressure-resistant structure of this lightweight cable protection conduit, during use, is as follows: the outer tube 1 directly bears the mechanical load of the external environment; the reinforcing component 3 effectively disperses stress, preventing pipe deformation or rupture; the inner tube 2 is in direct contact with the cable, protecting it from external environmental corrosion; and the buffer layer 4 effectively absorbs and disperses impact energy (such as...). Figure 4 As shown in the figure, the weight-reducing grooves 5 on the inner wall of the inner pipe 2 effectively reduce the weight of the protective pipe. The weight-reducing grooves 5, evenly distributed on the inner wall of the inner pipe 2, ensure weight reduction while maintaining the structural strength of the protective pipe (as shown in the figure). When connected to other pipes, the flange 6 is tightly connected to the flange 6 of other pipes or equipment via bolts, forming a sealed channel. This ensures continuous cable transmission within the protective pipe and facilitates installation and maintenance. The heat fusion connection allows for a tighter connection between the flange 6 and the outer pipe 1 (e.g., ...). Figure 1 (As shown).

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
