Description

Technical Field

[0001] The present invention relates to the technical field of wire and cable production, and particularly to a wire and cable cooling device. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy, information, and achieve electromagnetic energy conversion. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, a cable refers to an insulated cable, which can be defined as a collective body composed of the following parts: one or more insulated wire cores, and their respective possible coating layers, total protective layer, and outer protective layer. A cable can also have additional uninsulated conductors. During the production process of wires and cables, an extruder is used to attach a layer of wire and cable to the outside of the wire. Wires and cables are usually composed of insulating materials such as rubber, PVC, and rubber-plastic, so as to achieve the effects of protecting the core and avoiding electrical contacts.

[0003] The cooling of wires and cables is usually carried out in an immersion manner. Mainly, it is immersed through a long water tank in an immersion manner to complete the cooling. Because effective cooling needs to be ensured, the water tank must be very long under normal conditions to achieve the cooling effect of the wires and cables. However, this technology occupies a large area and requires a large investment in water resources, resulting in excessive waste of water resources during long-term use. And during continuous production, the heat dissipated by the wires and cables will cause the temperature of the surrounding cooling water to rise, and the increase in the temperature of the cooling water will reduce the cooling effect of the cable sheath. For this reason, we propose a wire and cable cooling device. Summary of the Invention

[0027] Next, a specific embodiment of the present invention will be elaborated in detail in conjunction with the attached Figures 1-9 drawings.

[0028] As Figure 1 shown: A wire and cable cooling device includes a mounting cylinder 1 with both ends of the mounting cylinder 1 being open. Mounting rings 4 are fixedly connected to both sides of the mounting cylinder 1. End covers 5 are provided on both sides of the mounting cylinder 1, and the end covers 5 are connected to the mounting cylinder 1 by bolts. A plurality of ventilation holes 6 are evenly provided in the middle of the end covers 5.

[0029] The mounting cylinder 1 is fixed to the ground by four support feet 2 at the bottom. The mounting cylinder 1 includes an upper cylinder part 3 and a lower cylinder part 7. The end of the upper cylinder part 3 is connected to the lower cylinder part 7 by a hinge. A handle for easy opening is further provided at the front end of the upper cylinder part 3, that is, the upper cylinder part 3 can be opened through the handle.

[0030] As Figure 1 and Figure 3 shown: A drum 8 is provided inside the mounting cylinder 1, and a spiral groove 9 is provided on the outer surface of the drum 8. Correspondingly, a wire outlet hole 10 is provided below one side of the front end of the lower cylinder part 7, and an inlet hole (not shown in the figure) is also provided below the other side of the rear end of the lower cylinder part 7. The wire and cable to be cooled extends into the mounting cylinder 1 through the inlet hole, then winds around the inside of the spiral groove 9, and then extends out through the wire outlet hole 10.

[0031] The drum 8 is connected to the end caps 5 at both ends through bearings. A motor 11 is provided on one side of the mounting cylinder 1. The motor 11 is installed on the ground through a fixing bracket 12. The output end of the motor 11 penetrates the end cap 5 and is connected to the end cap 5 through a bearing. A blower (not shown in the figure) is fixedly provided at the front end of the output end of the motor 11. The blower is arranged on one side of the mounting cylinder 1. A dust-proof cover 27 is further provided above the blower. The dust-proof cover 27 is fixed on one side of the mounting cylinder 1. The motor 11 is also connected to the dust-proof cover 27 through a bearing.

[0032] As Figure 5 and Figure 6 shown: A first gear 25 is fixedly provided at the end of the output end of the motor 11. The first gear 25 is inside the front end of the drum 8. An outer fixing ring 26 is fixedly provided on the inner side of the front end of the drum 8. Gears are provided on the outer ring of the outer fixing ring 26. The gears are in gear engagement with the first gear 25.

[0033] That is, open the upper cylinder part 3 through the handle, then extend the wire and cable into the interior of the mounting cylinder 1 through the inlet hole, then wind the wire and cable into the spiral groove 9, and finally extend out through the outlet hole 10. Then start the motor 11 to drive the blower to rotate, which will also drive the first gear 25 to rotate, and then the gears on the outer ring of the outer fixing ring 26 will rotate, so that the drum 8 rotates, realizing the rotation of the wire and cable in the spiral groove 9. Since a plurality of ventilation holes 6 are evenly provided in the middle of the end cap 5, the blower will cool the interior of the wire and cable located inside the mounting cylinder 1.

[0034] As Figure 8 shown: A plurality of cooling devices 14 are evenly provided inside the drum 8. The cooling devices 14 are circularly arranged, and the upper ends of the cooling devices 14 are slidably connected to the inner wall of the drum 8. Adjacent two cooling devices 14 are connected by a plurality of connecting rods 15. The connecting rods 15 are evenly distributed. The cooling devices 14 are filled with a coolant. Preferably, the coolant is water.

[0035] That is, when the drum 8 rotates, the cooling devices 14 can cool the wire and cable on the outer surface of the drum 8.

[0036] As Figure 7As shown: However, as the roller 8 rotates, the temperature of the coolant inside the cooling device 14 will gradually rise. At this time, it is necessary to replace the new coolant, otherwise the cooling effect will not be good. Based on this, the present application adopts the following technical solutions: The cooling device 14 is in a circular ring shape, and a plurality of cavities 13 are evenly arranged inside the cooling device 14. The lower ends of the cavities 13 are all open. The cavities 13 are used to store the coolant. The arrangement of the cavities 13 can, on the one hand, reduce the weight of the cooling device 14, and on the other hand, make the structural strength of the cooling device 14 better. A fixing ring 19 is arranged on the inner ring of the cooling device 14. A chute is arranged on the outer surface of the fixing ring 19. The cooling device 14 is slidably connected to the fixing ring 19. Notches 20 are arranged at both the upper and lower ends of the fixing ring 19. That is, when the cooling device 14 rotates, when the uppermost cavity 13 is at the notch 20, since the lower end of the cavity 13 is open, the coolant inside the cavity 13 will flow into the notch 20 from the opening, and since the other parts are provided with the fixing ring, the coolant inside the cavity 13 will not flow out.

[0037] As Figure 4 and Figure 9 shown: At this time, it is necessary to discharge the coolant with a higher temperature inside the cavity 13, and it is necessary to supplement the cavity 13 with new coolant after discharging the coolant with a higher temperature; that is, a drain pipe 16 and a water inlet pipe 17 are arranged inside the fixing ring 19. The drain pipe 16 is above the water inlet pipe 17. Connecting pipes 18 corresponding to the cooling device 14 are arranged on one side of both the water inlet pipe 17 and the drain pipe 16. The drain pipe 16 and the water inlet pipe 17 are mirror-symmetrically arranged. The connecting pipe 18 on one side of the drain pipe 16 is detachably connected to the notch 20 at the upper end of the fixing ring 19. The connecting pipe 18 on one side of the water inlet pipe 17 is detachably connected to the notch 20 at the lower end of the fixing ring 19; that is, when the coolant with a higher temperature flows into the upper notch 20 from the opening, it will enter the drain pipe 16 along the connecting pipe 18 and then be discharged; when the cavity 13 is supplemented with new coolant, the coolant in the water inlet pipe 17 will enter the lower notch 20 along the connecting pipe 18 and then enter the cavity 13 from the opening of the cavity 13, and so on in a cycle.

[0038] One end of the water inlet pipe 17 and the drain pipe 16 is closed, and the other end penetrates through the right end cover 5 and is fixedly connected to the end cover 5; the protruding part is connected to an external water inlet tank and a storage tank.

[0039] As Figure 6As shown: At this time, it is necessary to discharge the coolant with a higher temperature in the drain pipe 16; it is also necessary to introduce new coolant from the water inlet pipe 17. Based on this, the present application adopts the following solution: Rotating shafts are provided inside both the water inlet pipe 17 and the drain pipe 16. Triangular support frames 21 are fixedly provided at the ends of the water inlet pipe 17 and the drain pipe 16. One end of the rotating shaft penetrates the closed end of the water pipe and is connected to the closed end through a bearing, and the other end is connected to the triangular support frame 21 through a bearing; Spiral vanes are fixedly connected to the rotating shaft; The spiral vanes of the drain pipe 16 and the water inlet pipe 17 have opposite spiral directions. By rotating the rotating shaft, the spiral vanes are driven to rotate, so that the drain pipe 16 discharges the coolant with a higher temperature inside through the rotation of the spiral vanes, and the water inlet pipe 17 allows new coolant to enter the end of the water inlet pipe 17 through the rotation of the spiral vanes.

[0040] On one side of the front end of the cooling device 14, an inner fixing ring 22 is also fixedly provided. Gears are also provided inside the inner fixing ring 22. A third gear 23 is also provided inside the inner fixing ring 22. The third gear 23 meshes with the gear inside the inner fixing ring 22. A second gear 24 is provided at the front end of the third gear 23. The second gear 24 and the first gear 25 are in the same vertical plane and the second gear 24 is meshed and connected to the first gear 25.

[0041] The rotating shaft of the water inlet pipe 17 penetrates the third gear 23 and the second gear 24 and is fixedly connected to the third gear 23 and the second gear 24. The extending end is connected to the left end cover 5 through a bearing; The rotating shaft of the drain pipe 16 is fixedly connected to one side of the first gear 25, and the center line of the rotating shaft of the drain pipe 16 is consistent with the center line of the output end of the motor 11.

[0042] That is, when the output end of the motor 11 rotates clockwise, it will drive the gear of the outer fixing ring 26 to rotate clockwise, and will also drive the second gear 24 to rotate counterclockwise. At this time, it will also drive the third gear 23 to rotate counterclockwise, and then drive the gear of the inner fixing ring 22 to rotate counterclockwise. That is to say, the drum 8 rotates clockwise and the cooling device 14 rotates counterclockwise, which can meet the requirement that the cooling device 14 can cool the wires and cables on the drum 8. If they rotate coaxially, the cooling effect will be poor; It can also drive the rotating shafts inside the water inlet pipe 17 and the drain pipe 16 to rotate in opposite directions, so that the coolant with a higher temperature can be discharged from the drain pipe 16 through the spiral vanes, and new coolant can enter through the spiral vanes from the water inlet pipe 17.

[0043] The motor 11 in the present application can drive the fan, the drum 8, the cooling device 14, the rotating shaft of the water inlet pipe 17, and the rotating shaft inside the drain pipe 16 to rotate simultaneously.

[0044] That is, when the device is in use, open the upper cylinder part 3, then insert the wire and cable to be cooled into the inside of the installation cylinder 1 through the inlet hole, then wind it into the inside of the spiral groove 9, and then extend it out from the outlet hole 10. Start the motor 11, which drives the rotation of the output shaft of the motor 11. At this time, it will drive the fan, the roller 8, the cooling device 14, the rotating shafts of the water inlet pipe 17 and the rotating shaft inside the drain pipe 16 to rotate simultaneously to cool the wire and cable inside; and by evenly arranging a plurality of cavities 13 inside the cooling device 14, the lower ends of the cavities 13 are all open, and connection pipes 18 corresponding to the cooling device 14 are arranged on one side of the water inlet pipe 17 and the drain pipe 16, which can ensure effective cooling and the investment in water resources is also relatively small.

[0045] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
