Description

Technical Field

[0001] This utility model belongs to the technical field of guy wire sheaths, and in particular relates to a guy wire sheath for power engineering. Background Technology

[0002] To ensure the stability of power poles, steel strand guy wires are generally installed around them. One end of the guy wire is connected to the top of the pole, and the other end is tied to the ground. The guy wire sheath is a component used to protect the steel strand guy wires of the pole. It is brightly colored, reflective at night, and has a high visibility effect. The sheath has strong insulation properties, is resistant to high and low temperatures, is not easily deformed or cracked, is quick and easy to install, and has a long service life.

[0003] When the guy wire sheath is engaged with the steel strand, the contact area is not tight enough, leaving gaps. Rainwater can easily enter the inside of the guy wire sheath along the steel strand. Because the air circulation inside the guy wire sheath is very poor, once the rainwater enters, it is difficult to dry. The prolonged dampness inside the sheath leads to corrosion of the steel strand and shortens its lifespan.

[0004] To solve the above problems, a new type of cable sheath is needed. Utility Model Content

[0005] The purpose of this invention is to provide a guy wire sheath for power engineering, which solves the problems of poor waterproofing and ventilation in the existing technology.

[0006] To achieve the above objectives, this utility model provides a guy wire sheath for power engineering, including a thick guy wire tube. The top end of the thick guy wire tube is connected to the bottom end of a thin guy wire tube via a connector. The thick guy wire tube, the connector, and the thin guy wire tube are connected in pairs to form a guy wire channel. The bottom diameter of the connector is larger than the diameter of the thick guy wire tube. The bottom surface of the connector is provided with vent holes evenly distributed around the central axis of the thick guy wire tube. The vent holes are connected to the guy wire channel. A boss is provided in the guy wire channel at the top of the thin guy wire tube. A sealing element is provided on the top surface of the boss. The sealing element includes a first arc-shaped rubber sheet and a second arc-shaped rubber sheet. Insert rods are fixedly connected to both ends of the bottom surface of the first arc-shaped rubber sheet. Several insertion holes are evenly distributed along the length direction of the second arc-shaped rubber sheet at both ends of the top surface of the second arc-shaped rubber sheet. The insertion holes are adapted to the structure of the insertion rods.

[0007] Preferably, a water-retaining ring extends from the bottom edge of the side wall of the connector.

[0008] Preferably, the connector comprises a hemispherical shell and a cylindrical shell integrally connected, wherein the diameter of the hemispherical shell is equal to the diameter of the cylindrical shell and larger than the diameter of the draw tube.

[0009] Preferably, the top end of the hemispherical shell is sealed and fixedly connected to the bottom end of the draw tube, and the bottom surface of the cylindrical shell is provided with a threaded hole, which is located in the draw channel and is adapted to be connected to the external thread at the top end of the draw tube.

[0010] Preferably, the outer wall of the wire-drawing tube is provided with a reflective coating.

[0011] Therefore, the power engineering guy wire sheath with the above-mentioned structure has the following beneficial effects: it can improve the waterproof performance of the guy wire sheath by utilizing the structural size design of the sealing element and the connecting element, and the water-blocking ring, and it can also improve the ventilation performance of the guy wire sheath by utilizing the vent holes.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] Reference Figure 1-5 As shown, this embodiment provides a guy wire sheath for power engineering, including a thick guy wire tube 1. The top end of the thick guy wire tube 1 is connected to the bottom end of a thin guy wire tube 3 via a connector 2. The thick guy wire tube 1, connector 2, and thin guy wire tube 3 are connected in pairs to form a guy wire channel 4, which is used to thread steel strand guy wires. The bottom diameter of the connector 2 is larger than the diameter of the thick guy wire tube 1. The bottom surface of the connector 2 is provided with vent holes 5 evenly distributed around the central axis of the thick guy wire tube 1. The vent holes 5 are connected to the guy wire channel 4. The vent holes 5 can improve the ventilation performance of the guy wire sheath. At the same time, the vent holes 5 are located on the bottom surface of the connector 2, which can prevent rainwater from entering the guy wire sheath through the vent holes 5. A boss 6 is provided in the guy wire channel 4 at the top of the thin guy wire tube 3. A sealing element 7 is provided on the top surface of the boss 6. The boss 6 is used to support the sealing element 7, thereby improving the stability of the sealing element 7. The sealing element 7 includes a first arc-shaped rubber sheet 71 and a second arc-shaped rubber sheet 72. Insert rods 73 are fixedly connected to both ends of the bottom surface of the first arc-shaped rubber sheet 71. Several insertion holes 74, evenly distributed along the length of the second arc-shaped rubber sheet 72, are provided at both ends of the top surface of the second arc-shaped rubber sheet 72. The insertion holes 74 are structurally compatible with the insertion rods 73. Inserting the insertion rods 73 into the insertion holes 74 at different positions can change the size of the through hole between the first arc-shaped rubber sheet 71 and the second arc-shaped rubber sheet 72, thereby achieving sealing for steel strands of different sizes.

[0023] In use, the steel strand is threaded into the cable channel 4 of the cable sheath, and then the end of the steel strand is fixed to the ground. Next, according to the size of the steel strand, the insertion rod 73 on the first arc-shaped rubber sheet 71 is inserted into the appropriate insertion hole 74 on the second arc-shaped rubber sheet 72. This creates a sealed connection between the steel strand and the cable tube 3, preventing rainwater from entering the cable channel 4 through the cable tube 3 and improving the waterproof performance of the cable sheath. When rainwater seeps into the cable channel 4 through the tiny gap between the steel strand and the cable tube 3, the vent hole 5 allows for ventilation of the cable channel 4, preventing prolonged dampness inside the sheath, which could lead to corrosion of the steel strand and shorten its lifespan.

[0024] In a further optimized design, a water-blocking ring 8 is extended along the bottom edge of the side wall of the connector 2. The water-blocking ring 8 is used to prevent rainwater from entering the pull cable channel 4 through the vent hole 5, thereby further increasing the waterproof performance of the pull cable sheath.

[0025] In a further optimized design, connector 2 comprises an integrally connected hemispherical shell and a cylindrical shell. The diameter of the hemispherical shell is equal to the diameter of the cylindrical shell and larger than the diameter of the draw tube 1. The connection structure of the hemispherical shell and the cylindrical shell gives connector 2 a smooth outer surface, preventing serious personal injury or property damage from collisions with objects.

[0026] In a further optimized design, the top of the hemispherical shell is sealed and fixedly connected to the bottom of the thin draw tube 3, and a threaded hole is provided on the bottom surface of the cylindrical shell. The threaded hole is located inside the draw channel 4 and is adapted to the external thread at the top of the thick draw tube 1. The use of the threaded hole and the external thread enables a detachable connection between the connector 2 and the thick draw tube 1, thereby facilitating the maintenance of the draw tube sheath and the replacement of some parts.

[0027] In a further optimized design, a reflective coating is provided on the outer wall of the guy wire tube 1. The reflective coating is used to increase the visibility of the guy wire sheath and reduce the probability of the guy wire sheath being accidentally bumped.

[0028] Therefore, the power engineering cable sheath of this utility model with the above-mentioned structure can improve the waterproof performance of the cable sheath by utilizing the structural dimensions of the sealing element 7 and the connecting element 2 and the water-blocking ring 8, and can also improve the ventilation performance of the cable sheath by utilizing the vent hole 5.
