Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a horizontal watertight cable. Background Art

[0002] A watertight cable is a cable with waterproof performance, designed for wet, waterlogged and other environments, which can prevent moisture from penetrating into the cable interior, thus protecting the performance and safety of the cable.

[0003] At present, watertight cables are wrapped with copper wire or steel wire armor layers on the outer layer to increase the mechanical force of the cables, avoiding the breakage of the core wires or damage to the protective layer when the cables are dragged over a long distance. However, there is a lack of protection for the cables when they are subjected to external forces. For example, the patent document with the publication number CN219040106U in the prior art provides a tensile horizontal watertight cable. When the entire horizontal watertight cable is impacted by an external heavy object, the buffer ball is impacted first. The internal space of the buffer ball is compressed and becomes smaller under the impact force, thus offsetting a part of the impact force. Secondly, when the impact force is transmitted to the inside of the core wire mechanism, the elastic rubber column will be deformed first due to the impact, causing the volume to become smaller, making the entire core wire mechanism smaller in volume, thereby offsetting the impact force and playing a protective role for the transmission network line, the power signal line and the signal transmission line.

[0004] This device realizes the protection of the cable through the cooperation of the elastic rubber column and the buffer ball. On the one hand, the buffer ball and the polyurethane outer sheath are integrally formed, which has a relatively high manufacturing difficulty and affects the production efficiency of the cable. On the other hand, it is difficult for the buffer rubber column to provide effective buffering for the impact forces in all directions, resulting in a poor protection effect. Therefore, there is an urgent need for a horizontal watertight cable to solve the above problems. Summary of the Utility Model

[0005] In view of the above problems in the prior art that on the one hand, the buffer ball and the polyurethane outer sheath are integrally formed, which has a relatively high manufacturing difficulty and affects the production efficiency of the cable, and on the other hand, it is difficult for the buffer rubber column to provide effective buffering for the impact forces in all directions, resulting in a poor protection effect, the present utility model is proposed.

[0006] Therefore, the purpose of the present utility model is to provide a horizontal watertight cable, aiming to solve the problems that on the one hand, the buffer ball and the polyurethane outer sheath are integrally formed, which has a relatively high manufacturing difficulty and affects the production efficiency of the cable, and on the other hand, it is difficult for the buffer rubber column to provide effective buffering for the impact forces in all directions, resulting in a poor protection effect.

[0007] To solve the above technical problems, the present utility model provides the following technical solution: A horizontal watertight cable includes a cable core main body. The cable core main body includes a wrapping layer. Inside the wrapping layer are arranged a transmission network line, a power signal line and a signal transmission line. It also includes a tensile protection member arranged outside the wrapping layer, an energy absorption protection member arranged inside the wrapping layer, and the voids inside the wrapping layer are filled with a watertight sealant.

[0008] The energy-absorbing protection member includes an annular buffer sleeve, on which a plurality of hollow cavities are arranged at equal intervals in a ring shape, and metal foam is arranged inside the annular buffer sleeve.

[0009] As a preferred embodiment of the transverse watertight cable of the present invention, wherein: the tensile protection member includes an inner sheath wrapped outside the wrapping layer, a plurality of galvanized steel wires are wound outside the inner sheath, and an outer sheath is wrapped outside the plurality of galvanized steel wires.

[0010] As a preferred embodiment of the transverse watertight cable of the present invention, wherein: a plurality of reinforcing ribs are fixedly arranged at equal intervals in a ring shape outside the outer sheath.

[0011] As a preferred embodiment of the transverse watertight cable of the present invention, wherein: the annular buffer sleeve is arranged at the axis center of the wrapping layer.

[0012] As a preferred embodiment of the transverse watertight cable of the present invention, wherein: a plurality of tensile auxiliary members are arranged inside the wrapping layer, the tensile auxiliary member includes a protective sleeve, and a Kevlar fiber rope is arranged inside the protective sleeve.

[0013] As a preferred embodiment of the transverse watertight cable of the present invention, wherein: a plurality of anti-disengagement positioning rings are fixedly arranged at equal intervals outside the protective sleeve.

[0014] The beneficial effects of the present invention:

[0015] 1. By arranging an energy-absorbing buffer member in the middle of the cable core main body, the present invention utilizes the deformation cooperation of the annular buffer sleeve and the hollow cavity to achieve preliminary energy absorption. Subsequently, the porous structure of the metal foam can collapse when subjected to pressure, increasing the stress area, thereby providing a good shock absorption effect. The two cooperate to effectively protect the cable core main body in all directions, and the process is simple and convenient for popularization and use.

[0016] 2. By arranging a plurality of tensile auxiliary members to cooperate with the galvanized steel wires, the present invention can further enhance the tensile effect of the cable. At the same time, the reinforcing ribs arranged on the outer sheath can help reduce the wear of the cable during dragging and improve the service life. Description of the Drawings

[0023] To make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model is provided in conjunction with the accompanying drawings of the specification.

[0024] Embodiment 1

[0025] Referring to Figures 1-3 , this is the first embodiment of the present utility model, providing a transverse watertight cable. This transverse watertight cable includes a cable core body 1. The cable core body 1 includes a wrapping layer 101. Inside the wrapping layer 101, there are a transmission network line 102, a power supply signal line 103 and a signal transmission line 104. It also includes a tensile protection component 2 arranged outside the wrapping layer 101. An energy absorption protection component 3 is arranged inside the wrapping layer 101, and the void inside the wrapping layer 101 is filled with a watertight sealant 4.

[0026] In the above technical solution, the energy absorption protection component 3 is arranged inside the wrapping layer 101 and in the middle of the transmission network line 102, the power supply signal line 103 and the signal transmission line 104. When the cable is impacted from the outside, the impact energy can be initially absorbed by the tensile protection component 2, and then the energy is further buffered by the energy absorption buffer component 3, reducing or avoiding damage to the cable.

[0027] The energy absorption protection component 3 includes an annular buffer sleeve 301. A plurality of hollow cavities 302 are arranged at equal intervals in a ring shape on the annular buffer sleeve 301, and a metal foam 303 is arranged inside the annular buffer sleeve 301.

[0028] In the above technical solution, the annular buffer sleeve 301 is made of synthetic rubber material, and the two ends of the hollow cavity 302 are blocked and sealed. When the annular buffer sleeve 301 is impacted, through the compression of the cavity of the hollow cavity 302 and the deformation of the annular buffer sleeve 301 itself, the impact energy can be initially absorbed and buffered. Subsequently, by using the porous structure of the metal foam, the impact energy is converted into its own structural collapse and deformation to achieve effective energy absorption.

[0029] The tensile protection member 2 includes an inner sheath 201 wrapped around the outer side of the wrapping layer 101. A plurality of galvanized steel wires 202 are wound around the outer side of the inner sheath 201, and an outer sheath 203 is wrapped around the outer side of the plurality of galvanized steel wires 202.

[0030] In the above technical solution, both the inner sheath 201 and the outer sheath 203 are made of polyethylene material. By utilizing the excellent heat resistance, cold resistance, electrical insulation and low water absorption of the polyethylene material, it can effectively protect the cable core body 1 inside. The plurality of galvanized steel wires 202 cooperate to form an armor layer, which is used to improve the mechanical strength of the cable core body 1, protect the cable, enhance the tensile, compressive, bending, extrusion and other effects of the cable, and at the same time can also enhance the bearing capacity of the cable.

[0031] A plurality of reinforcing ribs 204 are fixedly arranged at equal intervals in a ring shape on the outer side of the outer sheath 203.

[0032] In the above technical solution, the reinforcing ribs 204 and the outer sheath 203 are integrally formed. Through the arrangement of the plurality of reinforcing ribs 204, it not only helps to improve the tensile strength of the outer sheath 203, but also reduces the wear of the outer sheath 203 during cable dragging, enabling it to extend the service life, and the manufacturing process is of low difficulty, facilitating production and use.

[0033] The annular buffer sleeve 301 is arranged at the axis center of the wrapping layer 101.

[0034] In the above technical solution, the transmission network line 102, the power signal line 103 and the signal transmission line 104 are all arranged on the outer side of the annular buffer sleeve 301. After the water-tight sealant 4 fills the wrapping layer 101, the external impact force acts on the transmission network line 102, the power signal line 103 and the signal transmission line 104 through the medium of the water-tight sealant 4. At this time, the transmission network line 102, the power signal line 103 and the signal transmission line 104 will displace to transfer the force to the buffer sleeve 301, and the impact force is absorbed and buffered by the energy absorption buffer member 3 to prevent the transmission network line 102, the power signal line 103 and the signal transmission line 104 from being damaged.

[0035] During use, when the watertight cable is subjected to an external impact force, the inner sheath 201, galvanized steel wire 202, and outer sheath 203 can prevent the cable from deforming under stress and can also perform preliminary energy absorption and buffering. Subsequently, the impact force is transmitted through the medium of the watertight sealant 4 to the transmission network line 102, power signal line 103, and signal transmission line 104. The displacement of the transmission network line 102, power signal line 103, and signal transmission line 104 transfers the force to the energy absorption and buffering member 3. Through the compression of the cavity of the hollow cavity 302 and the deformation of the annular buffer sleeve 301 itself, preliminary energy absorption and buffering of the impact energy can be performed. Subsequently, by using the porous structure of the metal foam, the impact energy is converted into its own structural collapse and deformation to achieve effective energy absorption.

[0036] Embodiment 2

[0037] Refer to Figure 3 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a plurality of tensile auxiliary members 5 are provided inside the wrapping layer 101. The tensile auxiliary member 5 includes a protective sleeve 501, and a Kevlar fiber rope 502 is provided inside the protective sleeve 501.

[0038] In the above technical solution, by utilizing the characteristics of the Kevlar fiber rope 502, which is light in weight and high in strength, and cooperating with the protective sleeve 501, the mechanical strength of the cable can be further enhanced, providing a certain protective effect in terms of tensile strength, extrusion, etc.

[0039] A plurality of anti - detachment positioning rings 503 are fixedly arranged at equal intervals on the outer side of the protective sleeve 501.

[0040] In the above technical solution, through the setting of the anti - detachment positioning rings 503, the protective sleeve 501 can be effectively bonded to the watertight sealant 4, so that when the cable is subjected to a tensile force, the acting force can be effectively transmitted to the tensile auxiliary member 5, thereby avoiding direct damage to the cable core body 1.

[0041] The remaining structures are the same as those in Embodiment 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
