Technical Field
The invention relates to the technical field of cable production, in particular to an elastic pressure-resistant cable suitable for a high-pressure environment.
Background
Cables are typically formed by twisting several or groups of at least two conductors, each insulated from the other, often twisted around a center, with a highly insulating covering over the entire circumference. Has the characteristics of internal electrification and external insulation. Are commonly used to transmit power or information from one location to another.
The cable has various types and shapes, and can be suitable for various severe and complicated environments. However, most of existing cables are solid cables, which not only have heavy weight, but also are easily extruded by other parts inside the cables after being extruded or pressed, so that the cable body is broken, and equipment failure is caused; in addition, the elasticity is poor and cannot recover by itself after being pressed or pressed.
Disclosure of Invention
In order to solve the technical problem, the invention provides an elastic pressure-resistant cable suitable for a high-pressure environment.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
the utility model provides a withstand voltage cable of elasticity suitable for high pressure environment, includes cable body package group, from interior to outer in proper order cladding fire-retardant layer, armor, the wear-resisting surrounding layer outside cable body package group, cable body package group is internal to be covered and is used for buffering when the cable body is extruded or is pressed, offset pressure and extrude or press and provide the withstand voltage package group of resilience for the cable body after finishing.
Furthermore, the cable body package group comprises a shielding sheath and a plurality of cable bodies which are uniformly distributed in the shielding sheath along the circumference, and elastic insulating fillers are arranged between the cable bodies in the shielding sheath.
Furthermore, the elastic pressure-resistant package group comprises an elastic pressure-resistant sleeve which is attached to the inner side wall and the outer side wall of the shielding sheath, and a central bone rod which is located in the middle of the elastic pressure-resistant sleeve and used for central positioning, wherein a plurality of elastic buffer plates which play a role in connection and buffering are evenly distributed on the circumference between the central bone rod and the elastic pressure-resistant sleeve.
Furthermore, each elastic buffer plate is provided with a folded plate surface structure.
The invention has the beneficial effects that:
compared with the prior art, the elastic pressure-resistant bag group consisting of the elastic pressure-resistant sleeve, the elastic buffer plate and the central skeleton rod is arranged, so that the cable is hollow and has the characteristics of high elasticity and pressure resistance, the weight of the cable is reduced, and the cable body can be protected from being broken by the elastic pressure-resistant bag group after the cable is extruded or pressed; in addition, the cable has high elasticity, can be quickly reset after being extruded or pressed, and does not influence the use performance.
Drawings
The invention is further illustrated with reference to the following figures and examples:
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.
As shown in fig. 1, an elastic pressure-resistant cable suitable for high pressure environment comprises a cable body bag group, a flame-retardant layer 4, an armor layer 5 and a wear-resistant outer cladding layer 6 which are sequentially coated outside the cable body bag group from inside to outside.
The cable body package group comprises a shielding sheath 2 and eight cable bodies 1 which are uniformly distributed in the shielding sheath 2 in the circumferential direction, the cable bodies 1 are respectively provided with an insulating layer sheath, in order to further improve the insulating property of the cable, elastic insulating fillers 3 are filled in gaps among the eight cable bodies 1 in the shielding sheath 2, and the shielding sheath 2 has high elasticity besides shielding, so that the shielding sheath 2 cannot be easily broken when the cable is extruded or pressed.
The cable comprises a shielding sheath 2, wherein the inner side wall and the outer side wall of the shielding sheath 2 are coated with an elastic pressure-resistant bag group, the elastic pressure-resistant bag group is positioned at the center of a cable body and comprises an elastic pressure-resistant sleeve 7 attached to the inner side wall and the outer side wall of the shielding sheath 2 and a central bone rod 8 positioned at the center of the elastic pressure-resistant sleeve 7, four elastic buffer plates 9 are uniformly distributed on the circumference between the central bone rod 8 and the elastic pressure-resistant sleeve 7, the elastic buffer plates 9 are of a folded plate surface structure, two ends of each elastic buffer plate 9 are respectively connected to the central bone rod 8 and the elastic pressure-resistant sleeve 7, each elastic buffer plate 9 extends along the axial direction of the elastic pressure-resistant sleeve 7, the elastic buffer plates 9 play a role of connection on one hand and a role of buffering on the other hand, when the outer part of a cable is extruded or pressed, the elastic buffer plates 9 deform to extend to the empty space inside the, the phenomenon that the interior of the cable is mutually extruded can not occur, and the acting force of extrusion or pressing is absorbed in the process, so that the cable body 1 is protected from being crushed and broken. And after the cable is extruded or pressed, the elastic buffer plate 9 loses the pressure resisting force to the elastic buffer plate, and can automatically recover to give a reaction force to the elastic pressure-resistant sleeve 7, so that the cable is recovered to the original state, and the continuous use of the cable is not influenced.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
