[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0031] As shown in Figures 1-4 The utility model provides a kind of technical solutions: a kind of high toughness wear-resistant superconducting cable, including cable 3, the outside of cable 3 is provided with fault-tolerant toughness component 2, the outside of fault-tolerant toughness component 2 is provided with wear-resistant component 1;Wear-resistant component 1 includes wear-resistant sleeve 11, is provided with corrugated groove 111 on wear-resistant sleeve 11, wear-resistant muscle 12 is embedded and installed on corrugated groove 111, wear-resistant muscle 12 is provided with three, and three wear-resistant muscle 12 is annular distribution, and the included angle between adjacent two wear-resistant muscle 12 is equal, under the action of wear-resistant component 1, the surface of cable 3 is prevented from wearing, first under the action of corrugated groove 111, wear-resistant sleeve 11 forms expansion joint structure, the advantage of this structure is that when wear-resistant sleeve 11 is bent, under the action of corrugated groove 111, the fault-tolerant hole 221 space when bending is reserved, avoid wear-resistant sleeve 11 to appear the fracture such as material fatigue caused when bending, further under the action of wear-resistant muscle 12, wear-resistant sleeve 11 and friction surface exist certain spacing, when the cable 3 is rubbed with ground, first is rubbed with connecting muscle 13, to improve the service life of wear-resistant sleeve 11, solve the technical problem of superconducting cable surface wear.

[0032] More further, as Figures 2-4As shown: the fault-tolerant and resilient assembly 2 comprises an outer limiting sleeve 21, a fault-tolerant sleeve 22 and an inner limiting sleeve 23, the outer limiting sleeve 21 is embeddedly installed in the wear-resistant sleeve 11, the inner surface of the outer limiting sleeve 21 is embeddedly installed with the fault-tolerant sleeve 22, the fault-tolerant sleeve 22 is embeddedly installed with the inner limiting sleeve 23, the inner limiting sleeve 23 is provided with an embedded hole 231, the cable 3 is embeddedly installed in the embedded hole 231, the fault-tolerant sleeve 22 is provided with a fault-tolerant hole 221, the fault-tolerant hole 221 is annularly distributed, and the included angle between adjacent two fault-tolerant holes 221 is equal. Under the action of the fault-tolerant and resilient assembly 2, the irreversible damage of the cable 3 in the wear-resistant sleeve 11 is avoided when the cable 3 is twisted. First, under the action of the outer limiting sleeve 21, the fault-tolerant sleeve 22 and the inner limiting sleeve 23, the inside of the wear-resistant sleeve 11 is filled to avoid the cable 3 in the wear-resistant assembly 1 from being twisted and wound due to the large gap. Further, under the action of the fault-tolerant hole 221, when the cable 3 is twisted, the inside of the wear-resistant assembly 1 is completely filled. At this time, under the action of the fault-tolerant hole 221, the deformation can be generated according to the twisting degree, and the activity space is reserved for the twisting deformation, so as to avoid the damage of the cable 3 caused by the too large twisting degree, and the technical problem of the twisted and wound cable 3 in the wear-resistant sleeve 11 is solved.

[0033] In the above scheme, there is also a problem that the wear-resistant rib 12 is in a long-term wear state and is separated from the wear-resistant sleeve 11, such as Figure 3 As shown: in the present scheme, the connecting rib 13 is arranged between the adjacent two wear-resistant ribs 12, and the connecting rib 13 is connected with the corrugated groove 111. Since the wear-resistant rib 12 is annularly arranged in the corrugated groove 111, there is a certain spacing between the adjacent two wear-resistant ribs 12. When the wear-resistant rib 12 is in a long-term wear state during use, the wear-resistant rib 12 will be separated from the corrugated groove 111. At this time, under the action of the connecting rib 13, the same group of wear-resistant ribs 12 are connected and tightly sleeved on the corrugated groove 111, so as to improve the stability of the device during use.

[0034] In the above scheme, there is also a problem that the wear-resistant sleeve 11 is not completely filled, such as Figure 4 As shown: in the present scheme, the outer limiting sleeve 21 is provided with a convex groove 211, the number and size of the convex groove 211 are matched with the outer surface wall of the fault-tolerant sleeve 22, the outer surface wall of the inner limiting sleeve 23 is provided with a concave groove 232, the number and size of the concave groove 232 are matched with the inner wall of the fault-tolerant sleeve 22, and under the action of the convex groove 211, the outer limiting sleeve 21 and the fault-tolerant sleeve 22 are fully attached, the internal gap of the wear-resistant sleeve 11 is reduced, the cable 3 is prevented from being twisted in the wear-resistant sleeve 11, and further under the action of the fault-tolerant and resilient assembly 2 of the inner limiting sleeve 23, the inner limiting sleeve 23 and the fault-tolerant sleeve 22 are fully attached, the internal gap of the wear-resistant sleeve 11 is reduced, and the cable 3 is prevented from being twisted in the wear-resistant sleeve 11.

[0035] Working principle:

[0036] like Figures 1-4 As shown, the superconducting cable is first installed in a designated location. During use, the wear-resistant component 1 is used to prevent wear on the surface of the cable 3. Firstly, under the action of the corrugated groove 111, the wear-resistant sleeve 11 forms an expansion joint structure. The advantage of this structure is that when the wear-resistant sleeve 11 bends, the corrugated groove 111 provides space for the tolerance hole 221 during bending, preventing material fatigue-induced fracture of the wear-resistant sleeve 11 during bending. Secondly, when the wear-resistant rib 12 contacts the friction surface, firstly... Friction with the connecting rib 13 prevents the wear-resistant sleeve 11 from directly contacting the friction surface, thereby improving the service life of the wear-resistant sleeve 11. Furthermore, under the action of the outer limiting sleeve 21, the fault-tolerant sleeve 22, and the inner limiting sleeve 23, the inside of the wear-resistant sleeve 11 is filled. When the cable 3 is twisted, since the inside of the wear-resistant component 1 is completely filled, under the action of the fault-tolerant hole 221, it can deform according to the twisting force, reserving activity space for the twisting deformation and avoiding damage to the cable 3 due to excessive twisting force.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
