Description

Technical Field

[0001] The utility model relates to a cable, in particular to a cooling device for producing a medium-voltage cable. Background Art

[0002] Medium voltage cable refers to a cable with a rated voltage between 1 kV and 35 kV. Medium voltage cables are usually used in urban power grids, industrial areas, large buildings, underground highways and other places. Since the working environment may be relatively harsh, medium voltage cables need to have higher insulation strength and reliability. The conductor of the medium voltage cable usually uses a copper wire core, and the insulation layer may be made of materials such as cross-linked polyethylene or trifluoroethylene. These materials have high compressive strength and can ensure that the cable can operate stably for a long time in a complex environment. Among them, when the medium voltage cable is produced, the metal wire will pass through a mold, and the mold will extrude a high-temperature insulating sleeve, wrapping the metal wire inside, and then send it into a water tank, and use water to cool the high-temperature insulating sleeve so that the insulating sleeve solidifies on the outside of the metal wire.

[0003] In the prior art, in order to facilitate the cooling of the insulating sleeve, the length of the water tank is generally set longer to ensure the cooling and solidification effect. In order to prevent the insulating sleeve from sliding in contact with the bottom of the water tank, multiple support wheels are arranged at intervals in the water tank, and the support wheels are used to support the cable in a mobile manner. However, in actual production, different types of cables are produced, and the diameters of different cables cannot be consistent. The conventional support wheel is an annular groove with a V-shaped cross-section in the middle, which is used to support the cable in a rolling manner. Large-sized annular grooves are suitable for cables with large diameters, and large-sized annular grooves can be used for cables with small diameters. However, when the cable moves in the large-sized annular groove, it will swing left and right and deviate, which makes the cable easy to bend, resulting in the need for subsequent reshaping, which is very inconvenient. The replacement of the support wheel is inconvenient, so how to solve the above technical problems is the direction that technicians in this field need to work hard on. Summary of the invention

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] Example 1: See Figures 1 to 3 As shown, a cooling device for medium-voltage cable production includes a water trough 1 and a plurality of support wheels 2 arranged in the water trough 1, wherein the two sides of the water trough 1 are respectively a feed port 3 and a discharge port 4, and the plurality of support wheels 2 are arranged at intervals from left to right, wherein the feed port is arranged on the left side of the water trough, and the discharge port is arranged on the right side of the water trough.

[0027] A partition 5 is provided at the front and rear ends of the water tank 1, and a plurality of support grooves 6 are provided at intervals on the top of each partition 5. The support grooves 6 on the front partition 5 correspond to the support grooves 6 on the rear partition 5 one by one.

[0028] The support wheel 2 is installed in the water tank 1 via a connecting shaft 7, the middle part of the support wheel 2 is rotatably installed in the middle part of the connecting shaft 7, and the two ends of the connecting shaft 7 are detachably clamped in the corresponding support grooves 6 of the partitions 5 on both sides.

[0029] In this embodiment, the water tank is set beside the mold. After the metal cable passes through the mold, the mold will use high temperature to extrude the insulation sleeve and cover it on the outside of the metal cable. During the movement of the metal cable, the mold keeps extruding the high-temperature insulation sleeve and continuously covers the outside of the metal cable. Since the insulation sleeve is in a high-temperature state (biased to a molten state) at this time, in order to quickly solidify and shape the high-temperature insulation sleeve, it will enter the water tank through the feed port. The water tank has cooling water. In this way, the cable enters the water tank and is cooled and solidified by the cooling water, and then sent out from the discharge port for drying. After drying, it is rolled up, and the action is like this. Among them, when the cable moves in the water tank, the traction force of the rear end on the cable will not be too large (to prevent the cable from being broken or stretched). Since the cable has its own weight, in order to prevent it from sinking to the bottom of the water tank and sliding in contact with the bottom of the water tank to scratch the insulation sleeve on the outer surface of the cable, a support wheel is set to support the cable in motion, thereby preventing the cable from sinking to the bottom and causing scratches on the cable. Among them, there is an annular groove on the middle outer surface of the support wheel, and the cross-section of the annular groove is V-shaped. The annular groove is used to support and limit the cable in rolling, so that the cable moves along a straight line as much as possible in the water tank, so that the cable is as straight as possible, which is convenient for subsequent winding, reduces the difficulty of subsequent shaping, and prevents damage to the cable during subsequent shaping. Among them, by setting two partitions inside the water tank, the front partition is set close to the front inner wall of the water tank, and the rear partition is set close to the rear inner wall of the water tank, and multiple support grooves are set on the partitions. The support wheel is set in the support groove through the coupling clamp, so that the support wheel can be easily installed, disassembled, and replaced. If the cable size is different and it is necessary to replace the support wheel of different sizes, the support wheel can be directly lifted up to make the coupling detach from the top of the support groove to complete the disassembly, and then replace the new support wheel, and directly insert the end of the coupling into the support groove, which is convenient and quick to replace. If the cable is small and the distance between adjacent support wheels is too long, the cable may sink to the bottom. You only need to add more support wheels between the adjacent support wheels and put them into the support groove through the connecting shaft. It is convenient and quick. If you do not need so many support wheels, you only need to take out the support wheels.

[0030] A water supply pipe 8 is provided above the water tank 1, and at least one water outlet 9 is provided at the bottom of the water tank, and a drain pipe is connected to the water outlet 9 (the drain pipe is not shown in the figure). The water supply pipe is used to add water so that there is water in the water tank, and the water outlet is used to drain water so that the water in the water tank is flowing water, and the water temperature in the water tank is kept as low as possible to ensure the cooling effect. The water tank will be installed on the frame 10 to raise the water tank.

[0031] See also Figure 3As shown, a height adjusting member 11 is detachably placed in each of the supporting grooves 6 , and an end of the connecting shaft 7 is placed on the corresponding height adjusting member 11 .

[0032] The height adjustment member 11 includes an adjustment plate 12, and an adjustment positioning groove 13 is provided on the inner side of the adjustment plate 12, and the top of the adjustment positioning groove 13 is connected to the top surface of the adjustment plate 12;

[0033] An extension plate 14 is respectively disposed on both sides of the adjustment plate 12 . The adjustment plate 12 is inserted into the support groove 6 , and the extension plate 14 is mounted on the partition plate 5 .

[0034] In this embodiment, since cables of different sizes have different heights, if the bottom of the coupling directly contacts the bottom of the support groove, cables of different sizes can be immersed in the water of the water tank and cooled by the water in the water tank. However, since the water supply pipe is located at the top, water will always be added to the water tank, and the water tank is a structure with an open top, the water in the upper layer will directly contact the air, so the water temperature in the upper layer will be lower, and the water temperature in the lower layer will be higher. Therefore, in order to ensure the cooling effect of cables of different sizes, the end of the coupling is supported and limited by setting a height adjustment member, and the distance between the bottom of the coupling and the bottom of the water tank is adjusted, so as to ensure the cooling efficiency and effect of the cable as much as possible. Among them, different height adjustment members have different depths of adjustment positioning grooves. Therefore, it is only necessary to select a height adjustment member with an adjustment positioning groove of corresponding depth according to actual conditions to be suitable for cooling cables of different sizes. Among them, the adjustment plate is directly inserted into the support groove, and its side is contacted on the partition through an extension plate to limit the adjustment plate to prevent the height adjustment member from moving forward and backward and falling out of the support groove.

[0035] See also Figure 3 As shown, a slot 15 is provided on the bottom surface of the extension plate 14 , and both ends of the slot 15 pass through the left and right ends of the extension plate 14 . The partition 14 is inserted into the slot 15 , and the top of the partition 5 is against the top surface of the slot 15 .

[0036] The inner wall of the supporting groove 6 abuts against the side surface of the adjusting plate 12 .

[0037] In this embodiment, the slot is set, and the partitions on both sides of the support slot are inserted into the slot, so that the height adjustment member can be limited and prevented from shaking back and forth, thereby supporting and positioning the height adjustment member. Then the end of the connecting shaft is inserted into the adjustment positioning slot. The weight of the connecting shaft and the support wheel itself, plus the weight of the cable, can give the height adjustment member downward pressure, so that the height adjustment member will not move up and leave the support slot, thereby ensuring the stability of the position. At the same time, when the height adjustment member is disassembled, it only needs to give it an upward pulling force to drive the height adjustment member to move up, so that the slot is separated from the partition. It only needs to completely separate the adjustment plate from the support slot to achieve the rapid disassembly of the height adjustment member and the partition.

[0038] See also Figure 1 , 2 As shown, the top of the feed port 3 and the discharge port 4 are connected to the top of the water tank 1, and the feed port 3 and the discharge port 4 are respectively covered with sponges 16.

[0039] When the cable passes through the feed port and the discharge port, it will rest against the sponge. The presence of the sponges on both sides can block the feed port and the discharge port to a certain extent, so that the water in the water tank is blocked as much as possible, and the water is prevented from flowing out of the water tank as much as possible. At the same time, the sponge at the water outlet can also wipe the surface of the cable to a certain extent when the cable is sent out of the water tank, wiping off most of the water on its surface, thereby improving the subsequent drying efficiency as much as possible, and at the same time, preventing water from dripping on the ground as much as possible.

[0040] See also Figure 1 , 2 As shown, the left and right sides of the water tank 1 are respectively provided with water collecting tanks 17 extending outward, and the tops of the water collecting tanks 17 are respectively arranged below the bottom surfaces of the feed port 3 and the discharge port 4;

[0041] The bottom of the water collecting tank 17 is respectively provided with a first drain port 18, and the first drain port 18 is connected to a first drain pipe (the first drain pipe is not shown in the figure).

[0042] The top height of the water collecting tank is lower than the top surface height of the water tank, and its top surface height is also lower than the bottom surface height of the feed port. The setting of the water collecting tank can collect most of the water flowing out from the water inlet and drain port when the water tank leaks out, and prevent water from dripping on the ground as much as possible, making the workshop cleaner and more environmentally friendly.
