Description

Technical Field

[0001] The invention belongs to the technical field of lined hoses, and in particular relates to an lined hose with a built-in solid-state light source. Background Art

[0002] The UV-CIPP process is a green, environmentally friendly, efficient, fast and widely used repair process in the trenchless repair technology of underground pipelines. The UV-CIPP process has the advantages of short construction period, no impact on traffic, no damage to original roads, low noise, no dust, resource saving, safety and reliability. The UV-CIPP process covers a wide range of pipeline diseases, the whole video controllability during the repair process is strong, the mechanical index of the liner pipe is high, and a single repair is effective for 50 years. The UV-CIPP process is to pull the liner hose material soaked in photosensitive resin into the original damaged pipe, inflate the liner hose material to fit tightly with the inner wall of the original damaged pipe, and use ultraviolet light to cure and harden the liner hose material, forming a firm pipe-in-pipe structure to achieve in-situ repair of the damaged pipe without excavation.

[0003] In order to achieve the curing of UV-CIPP lined hose in the pipeline, there are too many hardware and software devices involved, which are too complicated. The details are as follows:

[0004] (1) More than three bulky light stands are required.

[0005] (2) In order to improve the curing efficiency, the lamp holder needs to be retractable, which requires a motor system, a limit system, a feedback system, etc.

[0006] (3) The power of a single UV lamp reaches 18KW, which needs to be transmitted downward through an integrated cable. For the sake of system stability, multiple UV lamps are controlled by single circuits respectively, so the diameter of the integrated cable is thick. According to statistics of equipment currently on the market, the diameter of the integrated cable generally reaches more than 25mm.

[0007] (4) In order to take into account the single repair length of the UV-CIPP lined hose, the length of the integrated cable is generally more than 150 meters, which requires the design of a large and heavy reel system that carries the drag chain on the work vehicle.

[0008] (5) In order to ensure the stable operation of the drag chain system, a cable arrangement system, an anti-slot device, a metering system, etc. should be added to the reel system.

[0009] (6) The host computer needs to add multiple UV lamp control systems, metering systems, voltage and current monitoring systems, integrated cable short-distance early warning systems, integrated cable tension testing machine early warning systems, human-machine interfaces, etc.

[0010] (7) In order to make the lining hose fit tightly against the original pipeline, it needs to be inflated to maintain pressure, and giant metal ties are required at both ends.

[0011] (8) Field work is required, and the minimum configuration of the vehicle carrying the above systems is a 4.2-meter van. Due to the restrictions of urban roads, it is difficult for trucks to enter narrow roads or residential areas, which brings inconvenience to the work.

[0012] (9) It is very difficult to move the light rack in the confined space of the well. It requires 2-3 people to operate the light rack in the inner lining pipe. It is time-consuming and laborious to operate the inner lining hose, and it will cause damage to the inner lining pipe, which will cause great hidden dangers to the project quality. Summary of the invention

The solid sacrificial light source layer is photocured on the photosensitive resin layer after power is supplied, and the power source is reversed after curing.

[0019] Furthermore, the ultraviolet light sources are arranged linearly along the length direction of the lining hose, and light guide strips are fixedly arranged between the ultraviolet light sources on the same straight line. The light guide strips and the ultraviolet light sources form photosensitive resin isolation strips on the same straight line.

[0020] Furthermore, a wear-resistant layer is provided on the inner side of the inner membrane.

[0021] Furthermore, a honeycomb uniformly distributed layer is provided on one side of the wear-resistant layer corresponding to the photosensitive resin layer.

[0022] Compared with the prior art, the beneficial effects of the inner lining hose with a built-in solid-sacrificial light source proposed by the present invention are as follows: the present invention does not need to perform light curing by means of walking lights, eliminates bulky lamp stands and long cables, and can reduce labor intensity; the light curing is performed by means of an embedded light source, which makes the light curing more sufficient and uniform, and can effectively improve the curing efficiency of the inner lining hose; the light curing operating system is simplified, making the operation simple and easy, and reducing energy consumption.

[0023] Specifically: a flexible circuit board layer is added on one side of the photosensitive resin layer. According to the thickness of the inner lining hose, micro ultraviolet light sources of different densities are arranged on the circuit board. The electrodes of the ultraviolet light source are led out from the same end, and the ultraviolet light source is powered in the forward direction to emit light. After curing, the ultraviolet light source and the flexible circuit board are self-destructively melted into the inner lining hose. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example 1

[0034] See also Figure 1A lined hose with a built-in solid-sacrificial light source includes an outer anti-ultraviolet film 1, a middle photosensitive resin layer 3 and an inner film 5. The inner film 5 is a plastic film. The inner side of the inner film 5 is provided with a wear-resistant layer 4. The wear-resistant layer 4 can be a fiber woven layer to improve the wear resistance of the inner wall of the lining hose and ensure that the photosensitive resin layer 3 is not damaged during the construction process. A solid-sacrificial light source layer for curing the photosensitive resin layer 3 is provided on one side of the photosensitive resin layer 3, wherein the solid-sacrificial light source layer includes a flexible circuit board layer 6, and the flexible circuit board layer 6 is evenly distributed with ultraviolet light sources 7. The arrangement density of the ultraviolet light sources 7 is determined according to the thickness of the lining hose. The flexible circuit board layer 6 is located between the anti-ultraviolet film 1 and the photosensitive resin layer 3. The side of the flexible circuit board layer 6 corresponding to the photosensitive resin layer 3 is provided with an anti-permeation layer 2 of a transparent structure. The anti-permeation layer 2 can be a transparent plastic film, which is used to isolate the photosensitive resin layer 3 from the solid-sacrificial light source layer to prevent the photosensitive resin layer 3 from affecting the circuit of the flexible circuit board layer 6. After the solid-sacrificial light source layer is powered on, the photosensitive resin layer 3 is photocured. In order to provide the strength of the photosensitive resin layer 3 after curing, a glass fiber mesh is provided inside the photosensitive resin layer 3, and the glass fiber mesh is filled with photosensitive resin. After photocuring, the photosensitive resin layer 3 forms a glass fiber composite reinforcement layer. After curing, the power supply is reversed, and the ultraviolet light source 7 in the solid-sacrificial light source layer self-destructs and is melted into the inner lining tube body to form an integrated structure with the inner lining tube body.

[0035] The inner lining hose with built-in solid sacrificial light source of the present invention has few restrictive factors in construction, simple construction, convenient operation, simple operating system, low energy consumption, which can reduce construction costs, improve construction efficiency and project construction quality. On the one hand, there is no need to perform light curing by means of walking lights, and the bulky lamp stand and long cables are eliminated, which can reduce labor intensity. The light curing is performed by means of embedded light sources, which makes the light curing more sufficient and uniform, which can effectively improve the curing efficiency of the inner lining hose, simplify the light curing operating system, and make the operation simple and easy. On the other hand, during construction, the far end does not need a giant tying head for pressure-maintaining sealing, and the tying head at the near end (operating end) can be miniature, and there is no need to be equipped with large vehicles, reel systems carrying drag chains, etc., which can reduce construction costs, is not restricted by urban roads, and makes construction more convenient; the inner lining tube is directly light-cured after being inflated, and no personnel intervention is required in the inner lining tube, and no human damage will be caused to the inside of the inner lining tube, which can greatly improve construction efficiency and project construction quality.

[0036] Specifically, when stacking materials, the following are laid in order: anti-ultraviolet film 1, flexible circuit board layer 6, anti-permeation layer 2, photosensitive resin layer 3, inner film 5. A flexible circuit board layer 6 is added to one side of the photosensitive resin layer 3. According to the thickness of the inner lining hose, micro-ultraviolet light sources of different densities are arranged on the circuit board. During construction, the tube is pulled, inflated, forward powered, fully cured, and reverse powered, and the ultraviolet light source and the flexible circuit board are self-destructively melted into the inner lining hose.

[0037] Example 2

[0038] Reference Figure 2 As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the ultraviolet light sources 7 are linearly arranged along the length direction of the lining hose, and a light guide strip 8 is fixedly provided between the ultraviolet light sources 7 on the same straight line. The light guide strip 8 and the ultraviolet light source 7 form a photosensitive resin isolation strip on the same straight line. The setting of the light guide strip 8 can increase the transmission range of the ultraviolet light source 7 within the ultraviolet light source 7, improve the photocuring efficiency, and reduce the number of ultraviolet light sources 7 used, thereby reducing the production cost. On the other hand, the isolation strip formed by the ultraviolet light source 7 and the light guide strip 8 can have a good limiting effect on the photosensitive resin, so that the photosensitive resin is more evenly distributed on the circumference of the lining hose, which can ensure that after photosensitivity curing, the thickness of the photosensitive resin layer 3 is more uniform.

[0039] Example 3

[0040] Reference Figure 3 As another preferred embodiment of the present invention, the difference from Embodiment 2 is that a honeycomb uniformly distributed layer 9 is provided on one side of the wear-resistant layer 4 corresponding to the photosensitive resin layer 3. The honeycomb uniformly distributed layer 9 is a sponge layer. The honeycomb uniformly distributed layer 9 is used to lock the photosensitive resin in the photosensitive resin layer 3, so that the photosensitive resin is more evenly distributed in the photosensitive resin layer 3. After light curing, on the one hand, the thickness of the photosensitive resin layer 3 is kept consistent, and on the other hand, the mechanical strength of the photosensitive resin layer 3 can be enhanced.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
