Description

Technical Field

[0001] The utility model relates to the technical field of cable insulation layers, and specifically relates to a cooling structure for extruding cable insulation layers. Background Technique

[0002] The cable sheath refers to a sealed metal sheath wrapped around the outer layer of the cable to prevent water ingress. Electric energy has been widely transmitted by power cables in cities, and the generation of induced voltage in the high-voltage cable sheath is a common phenomenon in power cables. Excessive sheath voltage not only affects the safety of people and related equipment, but more importantly, the sheath voltage generates sheath circulating current. The sheath current not only causes energy loss, reduces transmission efficiency, but also raises the cable temperature, affects the cable life, and affects the cable transmission capacity.

[0003] After retrieval, the existing patent (publication number: CN210271906U) discloses a water-saving cooling device for a cable insulation layer extrusion production line, which includes an installation shell, an extruder, a fan, a spray head, and a circulating cooling mechanism. The extruder is installed on the installation shell, and the fan, the spray head, and the circulating cooling mechanism are installed on the installation shell. Along the conveying direction of the cable, the fan, the spray head, and the circulating cooling mechanism are arranged in sequence. The circulating cooling mechanism includes a water storage tank, a motor, a first transmission wheel, a second transmission wheel, a drainage shell, a first transmission belt, and a second transmission belt. The water storage tank is arranged directly below the cable insulation layer. The fan can initially cool the cable insulation layer, then the spray head sprays and cools the cable insulation layer atomized, and finally the circulating cooling mechanism cools the cable insulation layer.

[0004] When the existing cooling device is working, when the cable insulation layer is extruded into the shell, it is easy to cause chaos. When cooling, water stains hang on the surface of the cable insulation layer and are not easy to dry after cooling. Therefore, after cooling, it is necessary to wait for the water stains to dry before storage, so improvement is needed. Content of the Utility Model [[ID=,18]]

[0025] Embodiment 1

[0026] A preferred embodiment of the cooling structure for extruding the cable insulation layer provided by the present utility model is as Figure 1 Figure 2 and Figure 4 shown: It includes an outer shell 1, and a scraper mechanism 3 is fixedly installed on the outer wall of the outer shell 1. The scraper mechanism 3 includes a connecting rod 31, an electric lifting telescopic rod 32, a first connecting plate 33, a first scraper 34, a second connecting plate 35 and a second scraper 36. The electric lifting telescopic rod 32 is fixedly installed inside the connecting rod 31, the first connecting plate 33 is fixedly installed on the inner wall of the electric lifting telescopic rod 32, the first scraper 34 is fixedly installed on the bottom wall of the first connecting plate 33, the second connecting plate 35 is fixedly installed inside the connecting rod 31, and the second scraper 36 is fixedly installed at the bottom of the second connecting plate 35.

[0027] Among them: The extruded cable insulation layer is placed into the housing 1, and the cable insulation layer is sorted by three rollers 2 in the housing 1, which facilitates the cooling of the cable insulation layer by the water in the housing 1. After cooling, one end of the cable insulation layer is pulled out from the roller 2, passed through the first scraper 34, and the first connecting plate 33 and the first scraper 34 are lifted and lowered by the electric lifting sleeve rod 32, so that the first scraper 34 can be adjusted and approximated according to the thickness of the cable insulation layer, making the first scraper 34 close to the second scraper 36, and scraping off the impurities and water stains on the surface of the cable insulation layer sandwiched in the middle, achieving the effect of scraping off the dust and stains adhering to the outer wall of the cable insulation layer being cooled in the housing 1, so that after the cable insulation layer is cooled, the impurities can fall off and will not affect the processing and use of the cable insulation layer.

[0028] Embodiment 2

[0029] On the basis of Embodiment 1, a preferred embodiment of a cooling structure for extruding a cable insulation layer provided by the present utility model is as Figure 1 and Figure 3 shown: The inside of the housing 1 is movably connected with the roller 2, the outer wall of the roller 2 is connected with a movable shaft, and the outer wall of the rotating shaft is connected with a motor. The roller 2 is divided into three and evenly spread in the housing 1. The outer wall of the housing 1 is fixedly installed with an air drying frame 4. The inner wall of the air drying frame 4 is provided with a feed inlet 5. The inner wall of the feed inlet 5 is fixedly installed with a heat dissipation net 6. The bottom of the heat dissipation net 6 is fixedly installed with a driving motor 7. The output shaft of the driving motor 7 is fixedly connected with a rotating shaft 8 through a coupling. The top of the rotating shaft 8 is fixedly installed with a heat dissipation fan 9. The outer wall of the housing 1 is fixedly installed with a water outlet pipe 10. The inside of the water outlet pipe 10 is fixedly connected with a plug 11.

[0030] Among them: The cable insulation layer can be sorted by three rollers 2, which facilitates the cooling of the cable insulation layer by the water in the housing 1. And the driving motor 7 drives the rotating shaft 8 to rotate, so that the rotating shaft 8 drives the heat dissipation fan 9 to rotate. Thus, when the heat dissipation fan 9 rotates, it drives the air to generate wind power under the condition of high-speed rotation, and performs secondary cooling on the cable insulation layer. Then, the plug 11 is pulled outwards, so that the plug 11 falls off from the water outlet pipe 10, and thus the waste water in the housing 1 flows out through the water outlet pipe 10.

[0031] All the electrical components mentioned in this article are electrically connected to the external main controller and 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0032] In use, first place the device in a suitable position, then place the extruded cable insulation layer into the housing 1. The cable insulation layer is sorted by three rollers 2 in the housing 1, facilitating the cooling of the cable insulation layer by the water in the housing 1. After cooling, pull one end of the cable insulation layer out of the roller 2, pass it through the first scraper 34. The electric lifting sleeve rod 32 drives the first connecting plate 33 and the first scraper 34 to lift and lower, enabling the first scraper 34 to adjust and approach according to the thickness of the cable insulation layer, making the first scraper 34 close to the second scraper 36 to scrape off the impurities and water stains on the surface of the cable insulation layer sandwiched in the middle. Then, pass one end of the cable insulation layer into the outer frame 4 through the feed port 5. Next, turn on the power supply of the drive motor 7, causing the drive motor � to drive the rotating shaft 8 to rotate, and the rotating shaft 8 drives the radiator fan 9 to rotate. Thus, when the radiator fan 9 rotates, it drives the air to generate wind at high speed to perform secondary cooling on the cable insulation layer. Finally, after use, pull the plug 11 outwards to make the plug 11 fall off from the water outlet pipe 10, and the waste water in the housing 1 flows out through the water outlet pipe 10, thus completing the work.
