Description

Technical Field

[0001] This utility model belongs to the technical field of cable processing and cooling, and particularly relates to a cable cooling water seal device based on thickness self-adaptation. Background Technology

[0002] In the cable extrusion production process, the extruded cable usually needs to be immediately subjected to forced cooling in a cooling water tank to ensure that the temperature rise of the cable conductor is reduced rapidly, the insulation layer is stabilized, and dimensional accuracy and mechanical properties are guaranteed for subsequent processes such as traction, cabling, and winding. Therefore, in order to prevent the cooling water from overflowing from the end of the water tank, some existing cable production lines usually install an elastic sponge at the end of the water tank to block the overflow. The water seal and anti-overflow function are achieved by simply pressing against the outer surface of the running cable. Although this type of structure has low initial cost and is easy to install, it has weak ability to control the cooling water level and poor adaptability to the working conditions of the cable.

[0003] Under long-term continuous production conditions, the sponge's elastic recovery ability and compressibility gradually decrease due to the combined effects of repeated friction from the cable, immersion in cooling water, and its own aging. The shape of the sealing surface is also prone to permanent deformation, resulting in a significant decrease in the end water seal effect. Cooling water easily overflows along the outer surface of the cable or the gap between the sponge and the water tank wall, making it difficult to maintain the actual water volume in the cooling water tank at the expected level and set liquid level. At the same time, when the effective water depth of the water tank is insufficient, the running cable cannot be completely covered by the cooling water, and the actual cooling length and cooling area are weakened, resulting in insufficient cable cooling, high conductor and insulation temperature, which can easily cause uneven insulation shrinkage, fluctuation in outer diameter, and increased surface defects. This, in turn, has an adverse effect on subsequent traction stability, cable quality, and the overall performance of the finished cable. Therefore, the existing cooling water tank end anti-overflow structure that relies on a single sponge for support is no longer able to meet the technical requirements of continuous, long-cycle stable cable production for cooling uniformity and precise water level control. It is necessary to improve the end sealing structure of the cooling water tank. Summary of the Invention

[0004] In order to overcome the technical problems described in the background, this utility model provides a cable cooling water sealing device based on coarseness self-adaptation. Through the combined use of coarseness self-adaptive ring water-blocking structure, triangular groove and water collection bucket, reliable end sealing and stable cooling water level are achieved, which can effectively ensure that the cable is fully cooled. Moreover, the components are easy to disassemble and assemble, and can adapt to specification switching and long-cycle continuous production.

[0005] The technical solution of this utility model is as follows: a cable cooling water sealing device based on thickness adaptation, including a triangular groove, an upper pressure sponge, a pressure ring, a water collection bucket, an end support leg, and a main drain interface. The left and right ends of the triangular groove are respectively provided with a ring water-proof structure that adapts to the cable thickness. The ring water-proof structure includes a pressure ring and an upper pressure sponge. The upper pressure sponge is bent and deformed to wrap around the cable from top to bottom and press it against the bottom of the triangular groove. The pressure ring is nested on the triangular groove and presses against the upper end of the upper pressure sponge. The triangular groove is provided with a water collection bucket for collecting water overflowing from the end of the triangular groove below the end that extends out of the pressure ring. The bottom of the triangular groove, in the part away from the direction of cable travel, is provided with a main drain interface for draining water out of the triangular groove.

[0006] Furthermore, a front stop block and a rear stop block are provided on both the left and right sides of the upper end of the triangular groove. The front stop block and the rear stop block are located on the same end and the same side of the triangular groove. The front stop block is relatively close to the end of the triangular groove, and a pressure ring is abutted between the front stop block and the rear stop block.

[0007] Furthermore, the pressure ring has a counterweight at the bottom and a short nail on the inner top for insertion into the pressure sponge.

[0008] Furthermore, on the water collection bucket located in the triangular groove facing the direction of cable segment movement, an end box is provided at the upper end facing the direction of cable segment movement, and a supporting sponge is provided inside the end box to support and wrap around the cable segment from bottom to top.

[0009] Furthermore, the bottom of the water collection tank is equipped with a tank drain interface, and the tank drain interface and the main drain interface are respectively connected to the return water pipe of the external cooling water circulation system.

[0010] The beneficial effects of this utility model due to the adoption of the above-mentioned technology are as follows: 1. This utility model utilizes a ring-shaped water-blocking structure formed by the cooperation of an upper pressure sponge and a pressure ring. The upper pressure sponge bends and deforms when the cable passes through, enabling adaptive wrapping and pressing for cable segments of different diameters and coating roughness. This creates a continuous annular water seal at the end of the triangular groove. Compared to end structures that rely solely on a single sponge for simple pressing, this design allows the pressure ring to continuously apply pressure to the upper pressure sponge under its own weight during long-term cable operation. This ensures the upper pressure sponge maintains a good sealing effect, significantly reducing the amount of cooling water overflowing from the end. It also makes it easier to maintain the cooling water level in the triangular groove at the set height, ensuring that the cable is essentially completely covered by cooling water within the triangular groove. This effectively guarantees the cooling length and cooling area, avoiding poor insulation and dimensional fluctuations caused by insufficient local cooling.

[0011] 2. Because the inner diameter of the pressure ring is larger than the height of the triangular groove, the pressure ring can be lifted upwards along the end of the triangular groove and directly detached from the end. Combined with the upper pressure sponge connected by short nails, the entire assembly can be removed or replaced. This allows operators to quickly open the end channel of the triangular groove and inspect and replace the sponge component when switching cable specifications, threading cables, or performing routine cleaning. Compared to traditional structures that use adhesive or rigid pressure plates to fix the sponge, this significantly improves the maintainability and replaceability of the end sealing assembly, reduces downtime, and promotes the flexibility and high efficiency of cable production lines.

Detailed Implementation

[0019] Example 1: As Figures 1-6As shown, this utility model provides a cable cooling water sealing device based on thickness self-adaptation, including a triangular groove 1, an upper pressure sponge 2, a pressure ring 3, a water collection tank 7, support legs, and a main drainage interface 10. The triangular groove 1 is horizontally supported on the ground by the support legs with its opening facing upwards. The upper opening of the triangular groove 1 is provided with a spray nozzle of the cooling water circulation system, forming a situation where cold water is sprayed onto the cable segment 4. The left and right ends of the triangular groove 1 are respectively provided with a ring-shaped water-proof structure that is self-adaptive to the cable thickness. The ring-shaped water-proof structure includes... The device includes a pressure ring 3 and an upper pressure sponge 2. The upper pressure sponge 2 is bent and deformed to wrap around the cable from top to bottom and press it against the bottom of the triangular groove 1. The pressure ring 3 is nested on the triangular groove 1 and presses against the upper end of the upper pressure sponge 2. The upper left and right sides of the end of the triangular groove 1 are provided with a front end block 14 and a rear end block 15. The front end block 14 and the rear end block 15 are located on the same end and the same side of the triangular groove 1. The front end block 14 is relatively close to the end of the triangular groove 1, and the pressure ring 3 is attached between the front end block 14 and the rear end block 15.

[0020] Among them, the requirement for the upper pressure sponge 2 is that when the cable segment 4 is not placed inside the cable segment 4, the upper pressure sponge 2 can fully shrink to the point of having no elasticity before being embedded in the triangular groove 1, and can also push the pressure ring 3 upward.

[0021] The triangular groove 1 has a water collection bucket 7 below the end of the extension of the pressure ring 3. The water collection bucket 7 can collect the water overflowing from the end of the triangular groove 1. The bottom of the water collection bucket 7 is provided with a bucket drain interface 8. The bottom of the triangular groove 1, in the part facing the direction of cable advance, is provided with a main drain interface 10. The bucket drain interface 8 and the main drain interface 10 are respectively connected to the return water pipe of the external cooling water circulation system, which can complete the drainage operation of the triangular groove 1.

[0022] The main drain port 10 is located at the bottom of the triangular groove 1, towards the direction of cable movement. This is because when the cable segment 4 moves out of the triangular groove 1, a large amount of water is carried out. By placing it near the end where the cable segment 4 moves out of the triangular groove 1, the amount of water leaking from this end to the corresponding water collection tank 7 can be reduced, thus avoiding accidental water splashing in excessive situations.

[0023] like Figure 4 As shown, the support leg includes a central support leg 11 and an end support leg 9. The left and right ends of the triangular groove 1 are provided with end support legs 9 and the center is provided with a central support leg 11, forming a three-point support groove structure.

[0024] like Figure 6As shown, the pressure ring 3 has a counterweight 13 at the bottom and a short nail 16 for inserting into the upper pressure sponge 2 on the inner side of the top. The counterweight 13 is pressed against the inner side of the bottom of the pressure ring 3 and is threaded into by a locking bolt 12 that runs from top to bottom through the bottom of the pressure ring 3, so as to achieve relative fastening between the counterweight 13 and the pressure ring 3. The pressure ring 3 is also relatively fixed to the upper pressure sponge 2 by the short nail 16 and is clamped at the end of the triangular groove 1 by the front end stop 14 and the rear end stop 15. This makes the upper pressure sponge 2 relatively locked at the end of the triangular groove 1. Since the upper pressure sponge 2 is made of elastic sponge, it can adapt to the thickness of the cable section 4 and wrap around it, thus achieving good water resistance at the end of the triangular groove 1.

[0025] like Figure 1 As shown, on the water collection bucket 7 located in the triangular groove 1 facing the direction of cable segment 4, there is an end box 6 at the upper end facing the direction of cable segment 4. The end box 6 is provided with a supporting sponge 5 for supporting and wrapping around the cable segment 4 from bottom to top. In this way, the part of the cable segment 4 that is separated from the cooling water is wiped by the supporting sponge 5, preventing the cable segment 4 from carrying the cooling water to the next process.

[0026] During operation, since the inner diameter of the pressure ring 3 is much larger than the height of the triangular groove 1, the pressure ring 3 can be pulled upwards and detached from the end of the triangular groove 1. This makes it easy to remove the pressure sponge 2, which greatly facilitates the loading of the cable segment 4 onto the triangular groove 1.
