[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] See also Figures 1 to 8 The present invention provides a high temperature resistant wire and cable for outdoor use, comprising a core body 1, a first sheath 2 is sleeved on the core body 1, a second sheath 3 is sleeved on the first sheath 2, a partition mechanism is fixedly connected to the second sheath 3 and the first sheath 2 at intervals in an array, a first cavity 4 is formed between every two partition mechanisms and the first sheath 2 and the second sheath 3, and a contraction mechanism for circulating and driving a low-temperature medium into the first cavity 4 is fixedly connected to the inner wall of the first sheath 2 at intervals in an array.

[0032] The provided separation mechanism separates the space outside the core body 1, and forms a plurality of first cavities 4 between the first sheath 2 and the second sheath 3. The number of the formed first cavities 4 matches the wires and cables used. At the same time, due to the differences in the positions of the wires and cables when in use, the medium temperatures in the first cavities 4 are different. When the medium temperature in one or more of the first cavities 4 rises, the low-temperature medium in other positions is driven to flow into the high-temperature first cavity 4 through the provided contraction mechanism, thereby reducing the temperature in the high-temperature first cavity 4, thereby enabling the entire wire and cable to work in a higher temperature environment, thereby increasing the service life of the wire and cable.

[0033] See also Figure 2 and Figure 4 The separation mechanism includes a first separation ring 5 fixedly connected between the first sleeve 2 and the second sleeve 3, a first separation plate 6 is fixedly connected in an array on the first separation ring 5, a first connecting hole 7 is opened in an array on the first separation ring 5, a second connecting hole 8 is opened in an array at a position close to the first connecting hole 7 on the first separation ring 5, a connecting plate 9 is fixedly connected between the first connecting hole 7 and the second connecting hole 8, the other end of the connecting plate 9 is fixedly connected to the adjacent connecting plate 9, a second separation ring 10 is fixedly connected in an array between the first sleeve 2 and the core body 1, a second cavity 11 is formed between each second separation ring 10 and the first sleeve 2 and the core body 1, and a first connecting hole 12 connecting the second cavity 11 and the first cavity 4 is opened on the first sleeve 2.

[0034] See also Figures 5 to 8The contraction mechanism includes a fixed seat 13 fixedly connected to the inner wall of the first sheath 2, a mounting groove 14 is provided on the fixed seat 13, first connecting blocks 15 are fixedly connected on both sides of the inner wall of the fixed seat 13, a moving seat 16 is slidably connected in the mounting groove 14, a mounting groove 17 is provided on the moving seat 16, support blocks 18 are fixedly connected on both sides of the top of the moving seat 16, a sliding wheel 19 is rotatably connected to the support block 18, a top rod 20 is slidably connected in the mounting groove 17, and second connecting blocks 21 are fixedly connected on both sides of the bottom end of the top rod 20 located in the mounting groove 17, each first connecting block 15 is fixedly connected with a connecting rope 22, the connecting rope 22 bypasses the sliding wheel 19 and is fixedly connected to the second connecting block 21, the top rod 20 passes through the fixed seat 13 and extends to the outside of the mounting groove 14, and an airbag 23 is fixedly connected to the bottom end of the fixed seat 13.

[0035] See also Figure 7 One end of the push rod 20 extending outside the mounting groove 14 is fixedly connected with a support rod 24, and the support rod 24 is fixedly connected to the connecting plate 9. The support rod 24 increases the contact area with the connecting plate 9, so that when the push rod 20 moves, the connecting plate 9 is deformed more through the support rod 24, thereby making the volume change of the first cavity 4 greater, and more medium is drawn in and discharged, thereby increasing the cooling effect.

[0036] See also Figure 8 One side of the airbag 23 extends into the installation groove 14 and is fixedly connected to the moving seat 16. Due to temperature changes, the volume of the airbag 23 can produce corresponding changes, thereby driving the moving seat 16 to move.

[0037] When the temperature of a section of the wire and cable rises, the airbag 23 expands due to the heat, and its volume increases, thereby pushing the moving seat 16 to move upward, and the movement of the moving seat 16 drives the support block 18 to move, and the movement of the support block 18 drives the sliding wheel 19 to move, and in the process of the movement of the moving seat 16, the support block 18 moves away from the first connecting block 15, and the length of the connecting rope 22 is fixed. The process of the sliding wheel 19 moving is equivalent to pulling the connecting rope 22 to move, and the connecting rope 22 drives the second connecting block 21 to move, and the movement of the second connecting block 21 drives the top rod 20 to move, and the movement of the top rod 20 drives the support rod 24 to move, and the movement of the support rod 24 drives the connecting plate 9 to move, so that the space of the first cavity 4 is increased, and the volume change of the airbag 23 is brought about The movable connecting plate 9 produces a larger deformation, which can draw more low-temperature medium into the second cavity 11, cool the area, and increase the cooling effect, so that the low-temperature medium in the adjacent second cavity 11 is drawn into the first cavity 4, and the low-temperature medium enters the second cavity 11 at this location through the second connecting hole 8 and the connecting pipe 28, thereby cooling the area, so that the wires and cables can work in a higher temperature environment, and increase the service life of the wires and cables. When the temperature at this location is reduced, the volume of the airbag 23 is reduced, and the medium in the second cavity 11 is discharged therefrom through the transmission structure, thereby forming a cycle, which can automatically control the temperature of the wires and cables, reduce the human intervention process, and reduce the human work cost.

[0038] See also Figure 5 A third connecting hole 27 is provided on the first sheath 2 of the first cavity 4 and the second cavity 11 adjacent to the fixing seat 13, and the corresponding first cavity 4 and the second cavity 11 are connected through the third connecting hole 27, so that the discharged medium flows through the corresponding second cavity 11 to the adjacent first cavity 4, and is finally discharged from the adjacent connected first cavity 4.

[0039] See also Figure 5 A second partition plate 25 is fixedly connected to the position array corresponding to the first partition plate 6 on the inner wall of the first jacket 2. A second connecting hole 26 is opened on one of the second partition plates 25 adjacent to the fixing seat 13. The second partition plate 25 divides the second cavity 11. When the volume of the first cavity 4 changes, the low-temperature medium in the adjacent corresponding second cavity 11 is drawn in to achieve cooling of the area. The second connecting hole 26 connects every two adjacent separated second cavities 11 so that the discharged medium enters the adjacent second cavity 11 through the second connecting hole 26.

[0040] The connecting plate 9 is made of a flexible material and has a certain degree of stretchability. The connecting plate 9 can shrink to change the volume of the first cavity 4 and draw the low-temperature medium into or out of the first cavity 4 .

[0041] See also Figure 4Both ends of the second connecting hole 8 are fixedly connected with connecting pipes 28, and the other end of the connecting pipe 28 passes through the first sheath 2 and is connected to the second cavity 11, so that the drawn low-temperature medium can enter the second cavity 11 from the adjacent first cavity 4 through the connecting pipe 28.

[0042] Both the connecting pipe 28 and the second connecting hole 26 are provided with a one-way valve, not shown in the figure, so that the low-temperature medium enters the second cavity 11 from the adjacent first cavity 4, and then enters the adjacent second cavity 11 from the second cavity 11, and is discharged through the third connecting hole 27, so that the drawn-in medium and the discharged medium are separated, thereby increasing the cooling effect.
