Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the utility model discloses a high-strength wind power cable, which comprises an outer sleeve 1, wherein an inner core 2 is arranged inside the outer sleeve 1; the tail end of the outer sleeve 1 is fixedly connected with a fixed end socket 11, the lower end of the fixed end socket 11 is fixedly connected with a bolt fixing plate 12, a movable cavity 13 is formed in the fixed end socket 11, and a metal wire 14 is arranged in the outer sleeve 1; inner core 2 is including sinle silk 21, sinle silk 21's outside is provided with interior protective sheath 22, interior protective sheath 22's outside is provided with insulating layer 23, the outside of insulating layer 23 sets up wearing layer 24, sliding sleeve 25 has been cup jointed at the both ends of inner core 2, sliding sleeve 25's middle part is provided with holding ring 26, spring 27 has been cup jointed at the both ends of sliding sleeve 25.

Specifically, the inner core 2 is sleeved inside the outer sleeve 1, and the sliding sleeve 25 is slidably connected inside the movable cavity 13.

In this embodiment, 2 both ends of inner core link to each other with the terminal structure behind the cable mounting, and overcoat 1 is adjacent the position at the terminal through 11 fixed mounting of fixed end, and overcoat 1 at first bears the effect of dragging when the cable receives wind-force influence to produce and drags, and a section of thick bamboo crosses 1 self intensity of overcoat and offsets the effect of dragging, and inner core 2 exempts from to receive the effect of dragging inside overcoat to prevent that inner core 2 and inside sinle silk 21 isogenic cable key part from receiving to drag the damage.

Specifically, the metal wires 14 are uniformly arranged in the outer sleeve 1 at equal intervals, and the direction of the metal wires 14 is the same as that of the outer sleeve 1.

In this embodiment, the metal wires 14 form a reinforcing rib structure uniformly arranged inside the jacket 1, so as to improve the tensile resistance of the jacket 1.

Specifically, the diameter of the positioning ring 26 is greater than the diameter of the openings at the two ends of the movable cavity 13, and the two ends of the spring 27 are respectively attached to the inner wall of the movable cavity 13 and the positioning ring 26.

In this embodiment, inner core 2 is stretched out by activity cavity 13 department during the cable installation, forms certain redundant length, and when overcoat 1 received wind-force influence to produce and drags the deformation, inner core 2 inevitable can produce relative displacement with overcoat 1, and then leads to spring 27 to take place elastic deformation, and when dragging and reducing, spring 27 resumes deformation to drive inner core 2 and reset.

Specifically, the outer sleeve 1 and the inner protective sleeve 22 are made of elastomer materials, the insulating layer 23 is made of plastic materials, and the wear-resistant layer 24 is made of wear-resistant rubber materials.

In this embodiment, overcoat 1 and interior protective sheath 22 mutually support and form two-layer protective structure inside and outside, play the guard action to the cable is whole, and the setting of insulating layer 23 prevents the cable electric leakage, because inner core 2 sets up at 1 inside activities of overcoat, the necessary meeting of looks adjacent surface produces the friction, sets up wearing layer 24 in order to reduce inner core 2 surface wear.

Specifically, the number of the positioning holes in the bolt fixing plate 12 is not less than 3.

In this embodiment, the bolt fixing plate 12 plays the effect of installation location to the fixing terminal 11, is main atress part when the cable receives wind-force and self action of gravity to produce and drags, sets up a plurality of locating holes in order to install a plurality of bolts, improves fixed structural strength.

When using, carry out fixed mounting with 1 both ends of overcoat through bolt fastening board 12, inner core 2 is outwards drawn forth by overcoat 1, and flow out a fixed length, connect the electricity after 1 outside crooked formation of overcoat, when the cable receives the wind-force effect to be dragged, drag at first to act on overcoat 1, lead to overcoat 1 to take place deformation, produce relative displacement with inside inner core 2, sliding sleeve 25 receives relative displacement to act on and takes place to slide in activity cavity 13, spring 27 takes place deformation this moment, weaken the cable when wind-force and resume original form and be, spring 27 resets and drives and drags inner core 2, make the crooked redundant length who originally reserves resume.

To sum up, this high strength's wind power cable constitutes inside and outside two-layer cable structure through setting up overcoat 1 and inner core 2, and inner core 2 uses as the main transmission structure of cable, when receiving factors such as wind-force and leading to the cable to receive the pulling effect, provides stretch-proofing effect through overcoat 1, has avoided leading to the fact directly to pull to inner core 2 that includes sinle silk 21 to a certain extent, reaches and prevents that cable and cable connection department from receiving the pulling effect and the purpose of damage.
