Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable protection sleeve technology, and more specifically to a durable cable protection sleeve. Background Technology
[0002] Cable conduit, also known as protective conduit or duct, is a conduit used in electrical installations to protect wires and cables, allowing them to be inserted and replaced. Cable conduit is a new type of conduit material widely used in power engineering. With the rapid development of underground power cable laying projects, higher requirements are placed on cable conduits. Cable conduits are suitable for telecommunications, power engineering, transportation, urban construction, and other fields.
[0003] Currently, for some buried cables, the cable conduit needs to be buried underground. The soil pressure will affect the cable conduit. The soil pressure mainly comes from the weight of the soil itself and external mechanical forces. These factors will affect the cable conduit. For example, when the soil's compressive strength is insufficient, the soil that originally protected the cable conduit from ground pressure will lose its protective function. At this time, the cable conduit is easily damaged by external mechanical forces, thus affecting the service life of the cable conduit, which needs to be improved. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a durable cable protection sleeve to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a durable cable protection sleeve, comprising a cable protection sleeve body, the cable protection sleeve body being composed of a galvanized steel wire mesh layer, a sleeve main body layer, a flame-retardant layer and an anti-corrosion layer, a semi-circular support cover being provided on the upper part of the cable protection sleeve body, a support base being fixedly connected to the bottom of the cable protection sleeve body, and multiple support frames being fixedly installed on both sides of the bottom of the semi-circular support cover, the bottom of the multiple support frames being fixedly installed on the top of the support base, and the multiple support frames being evenly distributed on both sides of the cable protection sleeve body.
[0006] Furthermore, connecting rods are fixedly installed between each of the plurality of support frames, and there are multiple connecting rods evenly distributed between the plurality of support frames.
[0007] Furthermore, the galvanized steel wire mesh layer is fixedly sleeved inside the main body layer of the casing, and the flame-retardant and anti-corrosion layer is fixedly sleeved on the outer wall of the main body layer of the casing.
[0008] Furthermore, the galvanized steel wire mesh layer is composed of multiple galvanized steel wire strips and multiple galvanized steel wire rings, and the multiple galvanized steel wire strips and multiple galvanized steel wire rings are welded together.
[0009] The technical effects and advantages of this utility model are as follows:
[0010] 1. This utility model, through the combination of a semi-circular support cover, support frame, connecting rod, and support base, facilitates the support of the soil above the cable protection sleeve, reduces the pressure exerted by the soil's own weight on the cable protection sleeve, and when the soil's compressive strength is insufficient, the semi-circular support cover bears external mechanical forces, thereby protecting the cable protection sleeve, improving its durability, and preventing damage to the cable protection sleeve from direct external mechanical forces when the soil's compressive strength is insufficient.
[0011] 2. This utility model, by adopting a flame-retardant and corrosion-resistant layer, makes the outer wall of the cable protection sleeve flame-retardant and corrosion-resistant, and by adding a galvanized steel wire mesh layer, increases the internal strength of the cable protection sleeve, which can further provide mechanical protection for the cable inside the sleeve.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The durable cable protection sleeve involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0018] Example 1:
[0019] like Figure 1-4As shown, a durable cable protection sleeve includes a cable protection sleeve body 1. The cable protection sleeve body 1 is composed of a galvanized steel wire mesh layer 11, a sleeve main body layer 12, and a flame-retardant and anti-corrosion layer 13. The galvanized steel wire mesh layer 11 is fixedly sleeved inside the sleeve main body layer 12, and the flame-retardant and anti-corrosion layer 13 is fixedly sleeved on the outer wall of the sleeve main body layer 12. The galvanized steel wire mesh layer 11 is composed of multiple galvanized steel wire strips 111 and multiple galvanized steel wire rings 112, and the multiple galvanized steel wire strips 111 and multiple galvanized steel wire rings 112 are welded together.
[0020] In this embodiment, the galvanized steel wire mesh layer 11, composed of galvanized steel wire strips 111 and multiple galvanized steel wire rings 112, facilitates the increase of the internal strength and bending resistance of the cable protection sleeve, reduces the deformation of the inner wall of the cable protection sleeve body 1 after long-term use, and thus provides further mechanical protection for the cable inside the sleeve. The flame-retardant and anti-corrosion layer 13 can be made of polyethylene (PE) with added flame retardants, which has good flame-retardant and anti-corrosion properties.
[0021] Example 2:
[0022] like Figure 1-4 As shown, a semi-circular support cover 2 is provided on the upper part of the cable protection sleeve body 1. A support base 4 is fixedly connected to the bottom of the cable protection sleeve body 1. Multiple support frames 3 are fixedly installed on both sides of the bottom of the semi-circular support cover 2. The bottom of the multiple support frames 3 is fixedly installed on the top of the support base 4. The multiple support frames 3 are evenly distributed on both sides of the cable protection sleeve body 1. A connecting rod 5 is fixedly installed between the multiple support frames 3. There are multiple connecting rods 5, and the multiple connecting rods 5 are evenly distributed between the multiple support frames 3.
[0023] In this embodiment, the support base 4 facilitates the support of the cable protection sleeve body 1, the support frame 3, and the semi-circular support cover 2. The multiple connecting rods 5 facilitate the horizontal connection of the multiple support frames 3 together. The semi-circular support cover 2 can withstand the vertical pressure of the soil's own weight. When the soil's compressive strength is insufficient, the semi-circular support cover 2 can withstand external mechanical forces, thereby protecting the cable protection sleeve body 1.
[0024] In summary, as Figure 1-4 As shown, this durable cable protection sleeve allows the cable to pass through the inside of the cable protection sleeve body 1 during use, protecting the cable. When the cable protection sleeve body 1 is buried underground, the semi-circular support cover 2 supports the soil above the cable protection sleeve body 1, reducing the pressure exerted by the weight of the soil on the cable protection sleeve body 1. Furthermore, when the soil's compressive strength is insufficient, the semi-circular support cover 2 bears external mechanical forces, thereby protecting the cable protection sleeve body 1.
