Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liner hoses, in particular to a thin-walled, high-strength composite liner hose. Background Art
[0002] Underground pipelines are generally used to transport liquid media. During long-term use, due to the scouring and corrosion of the liquid medium on the pipeline, the pipeline will be damaged after a certain period of use. This form of damage includes scouring that causes the pipeline wall to become thinner and leaking, as well as corrosion and oxidation damage to the pipeline, and cracking caused by pipeline deformation and the formation of gaps. For this reason, it is often necessary to repair the pipeline. The pipeline lining hose repair is to use a hose with an outer diameter equal to or slightly smaller than the inner diameter of the pipeline to be repaired. Through a special U-pressing device, the cross-section is pressed into a double-layer U shape. Under the action of traction, it penetrates into the interior of the pipeline to be repaired. After being inserted into place, the pressure is used to open the lumen, restore it to a round shape, and fit with the inner wall of the outer pipeline to form a reliable composite pipe.
[0003] However, in the prior art, when the existing liner hose is pulled into the special U-pressure equipment, one end slides against the inside of the equipment and the other end slides against the ground, resulting in a section of the liner hose always generating a large friction force, thereby causing wear on the liner hose and shortening its service life. Utility Model Content
[0004] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a thin-walled, high-strength composite liner hose.
[0005] The technical solution of the utility model is as follows: a thin-walled, high-strength composite liner hose, comprising a liner hose body and a protective component, wherein the protective component is used to protect the liner hose body, and the protective component comprises a protective sleeve, which is in the shape of a hollow tube, and circular grooves are equidistantly provided on the outer circumference of the protective sleeve, and balls are rollingly connected to the inside of the circular grooves.
[0006] As a preferred embodiment, a hose opening is opened inside the inner lining hose body, and convex strips are fixedly connected with the outer circumference of the inner lining hose body at equal intervals.
[0007] As a preferred implementation, damping strips are equidistantly and fixedly connected to the inner wall of the protective sleeve, and the convex strips are in compression contact with the damping strips.
[0008] As a preferred embodiment, the outer wall of the lining hose body is sequentially coated with a material layer, a base layer and a reinforcement layer.
[0009] As a preferred embodiment, the inner wall of the lining hose body is sequentially covered with a main body layer and an absorption layer, and the thickness of the absorption layer is 10 mm to 12 mm.
[0010] As a preferred implementation, the material layer is made of glass felt.
[0011] As a preferred embodiment, the materials of the base layer and the main body layer are both carbon fiber and the thicknesses are both 3.4 mm to 8.6 mm.
[0012] As a preferred implementation, the reinforcement layer is an integrated structure of carbon fiber and epoxy resin.
[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] In the utility model, when repairing the pipeline, it is necessary to first pass resin glue into the interior of the lining hose body, and then put one end of the lining hose body into the flattening machine to flatten it by pulling. At this time, by arranging the protective sleeves on both ends of the lining hose body and rotating them, under the cooperation of the damping strips and the convex strips, there is a certain resistance between the protective sleeves and the lining hose body, so when the lining hose body is pulled, the protective sleeves will not be quickly separated, so that under the cooperation of the round groove and the round ball, the sliding connection of the lining hose body in the flattening machine is transformed into a rolling connection, and the sliding of the other end with the ground is also transformed into a rolling connection, which reduces a lot of friction, facilitates the movement of the lining hose body, greatly reduces the wear degree of the lining hose body, and improves its service life;
[0015] By setting the number of material layers, the lining hose body has high strength and corrosion resistance, and has good performance in protecting itself, absorbing impact and environmental protection, thereby improving its use effect and maintenance quality, and greatly optimizing and improving the economic and social benefits of the pipeline.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.
[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the utility model provides a technical solution: a thin-walled, high-strength composite liner hose, comprising a liner hose body 1 and a protective assembly 2, wherein the protective assembly 2 is used to protect the liner hose body 1, and the protective assembly 2 comprises a protective sleeve 201, which is in the shape of a hollow tube, and the outer circumference of the protective sleeve 201 is equidistantly provided with circular grooves 203, and the insides of the circular grooves 203 are rollingly connected with round balls 204, the inner part of the liner hose body 1 is provided with a hose port 101, and the outer circumference of the liner hose body 1 is fixedly connected with convex strips 102 at equal intervals.
[0025] In this embodiment, when repairing the pipeline, it is necessary to first pass resin glue into the interior of the lining hose body 1, and then put one end of the lining hose body 1 into a flattening machine and flatten it by pulling. At this time, by putting the protective sleeve 201 on both ends of the lining hose body 1 and rotating it, with the cooperation of the damping strip 202 and the convex strip 102, there is a certain resistance between the protective sleeve 201 and the lining hose body 1, so when the lining hose body 1 is pulled, the protective sleeve 201 will not be quickly detached, so that with the cooperation of the circular groove 203 and the round ball 204, the sliding connection of the lining hose body 1 inside the flattening machine is transformed into a rolling connection, and the sliding of the other end with the ground is also transformed into a rolling connection, which reduces a lot of friction, facilitates the movement of the lining hose body 1, greatly reduces the wear of the lining hose body 1, and improves its service life.
[0026] Example 2
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the inner wall of the protective sleeve 201 is equidistantly fixedly connected with a damping strip 202, and the convex strip 102 and the damping strip 202 are pressed and contacted with each other. The size of the damping strip 202 is larger than the size of the convex strip 102, which can ensure that during the movement of the liner hose body 1, the damping strip 202 can always effectively contact with the convex strip 102, providing a stable resistance to prevent the protective sleeve 201 from being separated too quickly;
[0028] The outer wall of the lining hose body 1 is covered with a material layer 3, a base layer 4 and a reinforcement layer 5 in sequence; the inner wall of the lining hose body 1 is covered with a body layer 6 and an absorption layer 7 in sequence, and the thickness of the absorption layer 7 is 10mm to 12mm; the material layer 3 is made of glass felt, which has a protective and buffering effect, and plays a key protective role in preventing the lining hose body 1 from being broken or damaged due to external impact; the base layer 4 and the body layer 6 are made of carbon fiber and the thickness is 3.4mm to 8.6mm, which has super hardness and tensile strength, and provides a solid skeleton for the entire lining hose; the reinforcement layer 5 is made of carbon fiber and The integrated structure of epoxy resin provides additional strength and durability for the lining hose body 1. At the same time, epoxy resin provides the necessary sealing to prevent liquids or other substances from penetrating into the interior of the lining hose body 1. This thickness is usually used to absorb or reduce the impact force of the internal fluid on the pipeline, thereby improving safety and preventing damage caused by excessively fast flow of the fluid. The above settings make the lining hose body 1 high-strength and corrosion-resistant, and have good properties such as protecting itself, absorbing impact force and environmental protection, thereby improving its use effect and maintenance quality, and greatly optimizing and improving the economic and social benefits of the pipeline.
