Description

Technical Field

[0001] The utility model relates to the technical field of optical cable manufacturing, in particular to a splash-proof water device for the production of stranded OPGW optical cables. Background Technique

[0002] The OPGW optical cable is installed on the top of the overhead pole tower in the power system and is used for lightning protection and communication functions of the power line. It can be laid along the highway or along the river together with the conductor. During the production and manufacturing process of the OPGW optical cable, in order to prevent damage to the optical fiber during use, generally an outer sheath is coated on the outer periphery of the cable core to protect the internal optical fiber. For the production of the outer sheath of the optical cable, generally, the outer sheath base material is extruded by an extruder in a high-temperature molten state and coated on the outer periphery of the cable core to form an outer sheath, and then fed into a cooling water tank. During the process of the optical cable entering the cooling water tank, the splash-proof water device can prevent the circulating water flowing out of the cooling water tank from splashing onto the surface of the optical cable and affecting the structural quality of the optical cable.

[0003] Chinese Patent No. CN220105366U discloses a splash-proof water device for the production of optical cables, including a water baffle. By arranging the water baffle between the bottom of the drainage tank and the cable, the cooling water is effectively blocked from splashing onto the surface of the optical cable, improving the quality of the optical cable surface, and having good application prospects and promotion value.

[0004] In the above patent document, there are certain gaps between both sides of the water baffle and the side walls of the drainage tank. When the flowing water in the drainage tank is large, the cooling water may pass through the gaps between both sides of the water baffle and the side walls of the drainage tank, splash above the water baffle, and thus splash onto the surface of the optical cable, resulting in poor water blocking effect and low practicability. Content of the Utility Model

[0005] The purpose of the utility model is to solve the following disadvantages existing in the prior art: when the flowing water in the drainage tank is large, the cooling water may pass through the gaps between both sides of the water baffle and the side walls of the drainage tank, splash above the water baffle, and thus splash onto the surface of the optical cable, resulting in poor water blocking effect and low practicability. Therefore, a splash-proof water device for the production of stranded OPGW optical cables is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A splash-proof water device for the production of stranded OPGW optical cables, including a cooling water tank and a drainage tank. A water baffle is arranged in the drainage tank, and the water baffle is installed in the drainage tank through a suspension assembly;

[0008] Both ends of the water baffle are fixedly installed with L-shaped sliding rails. An extension plate is symmetrically and slidably installed between the two sliding rails. The two extension plates are symmetrically arranged on the upper surface of the water baffle. A threaded rod is rotatably installed on the upper surface of the water baffle. A moving block is threadedly sleeved on the threaded rod. Two support rods are symmetrically and rotatably installed on the moving block. One end of each of the two support rods away from the moving block is respectively rotatably connected to the side of one of the two extension plates.

[0009] Preferably, one end of the threaded rod is fixedly installed with an adjusting block. The lower surface of the moving block is in sliding contact with the upper surface of the water baffle.

[0010] Preferably, the hanging assembly includes an L-shaped support plate fixedly installed on the upper surface of the water baffle and a sliding bracket hanging on the drainage trough. One end of the support plate is rotatably connected to the sliding bracket.

[0011] Preferably, a limiting rod is rotatably installed on the upper surface of the support plate. One end of the limiting rod away from the support plate is rotatably installed with a mounting plate. The mounting plate is connected to the sliding bracket through a connecting assembly.

[0012] Preferably, the connecting assembly includes a rotating column rotatably installed on the mounting plate and a connecting column fixedly installed on the sliding bracket. One end of the connecting column is provided with a threaded hole. Threads matching the threaded hole are provided on the surface of the rotating column. One end of the rotating column is threadedly inserted into the threaded hole.

[0013] Preferably, a sealing strip is fixedly installed at one end of the extension plate close to the side wall of the drainage trough. The sealing strip is a rubber strip.

[0014] In the present utility model, the beneficial effects are as follows:

[0015] 1. Through the mutual cooperation of the threaded rod, the moving block, the support rods and the sliding rails, the two extension plates on the water baffle can be driven to move away from each other, thereby increasing the overall width of the water baffle and the extension plates, avoiding the cooling water passing through the gaps between the two sides of the water baffle and the side walls of the drainage trough and splashing above the water baffle, achieving a better water blocking effect, playing a better protective role for the optical cable. The water baffle and the extension plates can be applied to drainage troughs of different widths, with high practicability;

[0016] 2. When the cooling water splashes on the lower surface of the water baffle, through the mutual cooperation of the limiting rod, the mounting plate, the sliding bracket and the connecting assembly, the water baffle is locked, and under the impact of the water flow, the water baffle can be effectively prevented from flipping.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Referring to Figures 1 - 4 , a splash-proof device for the production of stranded OPGW optical cables, including a cooling water tank 1 and a drain tank 2. A water baffle 3 is provided in the drain tank 2. The water baffle 3 is installed in the drain tank 2 through a suspension assembly. The suspension assembly includes an L-shaped support plate 10 fixedly installed on the upper surface of the water baffle 3 and a sliding bracket 11 suspended on the drain tank 2. One end of the support plate 10 is rotatably connected to the sliding bracket 11.

[0024] The sliding bracket 11 is disclosed in the Chinese patent with the publication number CN220105366U and the theme name of a splash-proof device for the production of optical cables. One end of the sliding bracket 11 can be suspended on the drain tank 2, and the other end is rotatably connected to the support plate 10. When not in use, the support plate 10 can be rotated upward to drive the water baffle 3 to rotate upward, so that the water baffle 3 is in a vertical state, ensuring that the water baffle 3 does not affect operations such as cable threading.

[0025] L-shaped sliding rails 4 are fixedly installed at both ends of the water baffle 3. An extension plate 5 is symmetrically slidably installed between the two sliding rails 4. The two extension plates 5 are symmetrically arranged on the upper surface of the water baffle 3. A threaded rod 6 is rotatably installed on the upper surface of the water baffle 3. A moving block 7 is threadedly sleeved on the threaded rod 6. Support rods 8 are symmetrically rotatably installed on the moving block 7. One end of each of the two support rods 8 away from the moving block 7 is respectively rotatably connected to the side edges of the two extension plates 5. One end of the threaded rod 6 is fixedly installed with an adjustment block 9. The lower surface of the moving block 7 is in sliding contact with the upper surface of the water baffle 3.

[0026] When the water baffle 3 is installed in the drainage trough 2, rotate the adjusting block 9 to drive the threaded rod 6 to rotate, and then drive the moving block 7 to move through the threaded rod 6. During the movement of the moving block 7, it will drive two extension plates 5 to move between two sliding rails 4 through two support rods 8, thereby driving the two extension plates 5 to move away from each other until one end of the extension plate 5 contacts the side wall of the drainage trough 2, increasing the overall width of the water baffle 3 and the extension plate 5, preventing the cooling water from passing through the gap between the two sides of the water baffle 3 and the side wall of the drainage trough 2 and splashing above the water baffle 3, achieving a better water blocking effect and providing better protection for the optical cable. The water baffle 3 and the extension plate 5 can be applied to drainage troughs 2 with different widths, and have high practicability.

[0027] A limiting rod 12 is rotatably installed on the upper surface of the support plate 10. One end of the limiting rod 12 away from the support plate 10 is rotatably installed with a mounting plate 13. The mounting plate 13 is connected to the sliding bracket 11 through a connecting component. The connecting component includes a rotating column 14 rotatably installed on the mounting plate 13 and a connecting column 15 fixedly installed on the sliding bracket 11. One end of the connecting column 15 is provided with a threaded hole, and the surface of the rotating column 14 is provided with threads matching the threaded hole. One end of the rotating column 14 is threadedly inserted into the threaded hole.

[0028] When the water baffle 3 is arranged in the drainage trough 2, the limiting rod 12 can be rotated to align one end of the rotating column 14 with the threaded hole, and then the rotating column 14 is rotated to insert one end of the rotating column 14 into the threaded hole, thereby connecting the rotating column 14 and the connecting column 15 together. When the cooling water splashes on the lower surface of the water baffle 3 and applies an upward impact force to the water baffle 3, the limiting rod 12 can effectively prevent the water baffle 3 from flipping.

[0029] A sealing strip is fixedly installed at one end of the extension plate 5 close to the side wall of the drainage trough 2. The sealing strip is a rubber strip. When one end of the extension plate 5 contacts the side wall of the drainage trough 2, the sealing strip can ensure the sealing between them, prevent the cooling water from seeping between them, and at the same time, the sealing strip can increase the friction between the extension plate 5 and the drainage trough 2. Under the action of the friction force, the installation stability of the water baffle 3 is effectively improved.

[0030] In the present utility model, when the water baffle 3 is installed in the drainage trough 2, by rotating the threaded rod 6 to drive the moving block 7 to move, during the movement of the moving block 7, it will drive two extension plates 5 to move between two sliding rails 4 through two support rods 8, thereby driving the two extension plates 5 to move away from each other until one end of the extension plate 5 contacts the side wall of the drainage trough 2, increasing the overall width of the water baffle 3 and the extension plate 5, preventing the cooling water from passing through the gap between the two sides of the water baffle 3 and the side wall of the drainage trough 2 and splashing above the water baffle 3, achieving a better water blocking effect and providing better protection for the optical cable. The water baffle 3 and the extension plate 5 can be applied to drainage troughs 2 with different widths, and have high practicability.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
