Description

Technical Field

[0001] The invention belongs to the technical field of ultraviolet light-curing pipelines, and in particular relates to a corrosion-resistant light-curing hose and a preparation process thereof. Background Art

[0002] After years of operation, various pipelines will inevitably suffer from various damages and leaks due to corrosion, poor operation and management, causing serious economic losses. However, replacing the entire line with new pipelines is not only a huge project, but also costly and long. How to restore the safe operation of pipelines economically, efficiently and quickly has attracted great attention at home and abroad. Therefore, the research on pipeline repair technology is of great significance.

[0003] A photocurable hose refers to a hose whose monomer, oligomer or polymer matrix is ​​cured under light induction. The ultraviolet light curing method uses a dragging method to drag the material hose into the underground pipeline. A walking robot moves inside the hose to cure the photocurable hose. After hardening by ultraviolet light curing technology, a new lining pipe is formed in the existing pipeline to replace the function of the original pipeline. This method requires a lot of pulling force when the material hose is dragged in. Generally, a ground film is pre-laid in the pipeline and then construction is implemented. This method has high construction efficiency and can complete the repair and renewal of the pipeline in just a few hours. At the same time, the construction process is environmentally friendly and safe, and has little impact on traffic.

[0004] After installation and curing, the light-curing hose needs to directly contact and withstand long-term uninterrupted corrosion from underground sewage, so its corrosion resistance is particularly important. Existing light-curing hoses are usually cured directly. Even if a small number of solutions are coated with an anti-corrosion paint layer in the later stage, the position of the hose is fixed after curing, and the top and side walls of the inner wall are limited by gravity, so a thicker coating cannot be applied, and it is difficult to further improve its corrosion resistance. Summary of the invention

[0005] The invention provides an anti-corrosion light-curing hose and a preparation process thereof. The light-curing hose has good corrosion resistance, fast curing speed, and can form a thicker and uniform anti-corrosion coating. The anti-corrosion layer is added during the preparation process, which can effectively prevent corrosion when in use and prolong the service life. The outer anti-UV film can prevent the external ultraviolet rays from prematurely curing the hose during transportation, storage, and transportation and installation after production. The transparent film can isolate each layer of resin so that the hose can be curled for transportation, and can limit the flow of the resin to ensure uniform thickness. After curing, the transparent film can be easily torn off to facilitate spraying of the anti-corrosion layer. The epoxy resin and filler used in the hose can improve the strength and hardness of the hose, thereby increasing its load-bearing capacity and service life. Due to the special properties of the epoxy resin and filler used, the hose has good high-temperature performance and can be used in a high-temperature environment. The materials and solvents used in the hose preparation process are all environmentally friendly materials and will not cause pollution to the environment.

[0026] Wherein, the anti-corrosion layer is sprayed by a mobile spraying mechanism, and the mobile spraying mechanism is detachably mounted on the front and rear ends of the middle part of a walking robot in a tube, and a plurality of ultraviolet curing lamps are arranged on the outer periphery of the middle part of the walking robot in the tube; a mobile spraying mechanism is detachably sleeved on the front and rear ends of the middle part of the walking robot; the mobile spraying mechanism is rotatably sleeved between the front and rear ends of the middle part of the walking robot; the mobile spraying mechanism comprises a hollow disc; the center of the hollow disc is rotatably sleeved on the protruding parts at the front and rear ends of the middle part of the walking robot, and bearings are respectively arranged at the front and rear parts of the sleeve; a sealing baffle is also arranged at the front and rear parts of the bearing; the sealing baffle is also embedded with a sealing ring sleeved on the outer circumferential surface of the protruding parts at the front and rear ends of the middle part of the walking robot; a plurality of groups of spraying guides are fixedly arranged on the outer ring of the hollow disc; the spraying guides comprise a clockwise inclined cyclone nozzle and a counterclockwise inclined cyclone nozzle; the inclination angles of the clockwise inclined cyclone nozzle and the counterclockwise inclined cyclone nozzle are different; the clockwise inclined cyclone nozzle The nozzle and the counterclockwise inclined cyclone nozzle respectively include a fixed arc panel and a flexible arc panel; the convex arc surface of the fixed arc panel and the flexible arc panel enclose an air outlet duct whose cross-sectional area gradually decreases outward; a narrow air outlet slit is formed at the outlet of the air outlet duct; the outer end of the fixed arc panel is longer than the outer end of the flexible arc panel, so that the air outlet from the air outlet duct adheres to the convex arc surface of the fixed arc panel under the Coanda effect and is blown out; the flexible arc panel is an elastic plate made of elastic material, and a piezoelectric deformation plate is fixedly attached to its back; the piezoelectric deformation plate The plate includes an elastic resin plate and piezoelectric ceramic plates attached to both sides of the elastic resin plate; by applying an electric field to the two piezoelectric ceramic plates respectively through an external circuit, one of the piezoelectric ceramic plates can be controlled to extend or the other to shorten, thereby controlling the bending degree of the piezoelectric deformation plate, thereby controlling the bending degree of the flexible arc panel, thereby controlling the volume of the air outlet and the size of the cross-sectional area at the outlet; an external pump air pipe pumps atomized anti-corrosion agent into the hollow disc; after the atomized air is further pressurized in the hollow disc, it is blown out through the air outlet.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] (1) The light-curing hose of the present invention has good corrosion resistance. An anti-corrosion layer is added during the preparation process. The fast curing speed can form a thicker and more uniform anti-corrosion coating. It can effectively prevent corrosion during use and extend the service life. The outer anti-UV film can prevent the external ultraviolet rays from causing premature curing during transportation, storage, and transportation and installation after the production is completed. The transparent film can isolate the various resin layers so that they can be curled for transportation, and can limit the flow of the resin to ensure uniform thickness. After the curing is completed, it can be easily torn off to facilitate the spraying of the anti-corrosion layer. The epoxy resin and filler used in the hose can improve the strength and hardness of the hose, thereby increasing its load-bearing capacity and service life. Due to the special properties of the epoxy resin and filler used, the hose has good high-temperature performance and can be used in high-temperature environments. The materials and solvents used in the hose preparation process are all environmentally friendly materials and will not cause pollution to the environment.

[0029] (2) The mobile spraying mechanism of the present invention has a high degree of automation: a walking robot is used for spraying operation, and the mobile spraying mechanism has a high degree of automation, which can greatly reduce manual operation and improve work efficiency. The coating can be quickly solidified during the spraying process, so it can assist in forming a thicker and more uniform anti-corrosion coating; uniform spraying: due to the use of clockwise and counterclockwise inclined cyclone nozzles, part of the torsion generated by the blown air on the hollow disc can be neutralized, thereby ensuring uniform spraying; the spraying thickness is adjustable: by adjusting the size of the air outlet of the clockwise and counterclockwise inclined cyclone nozzles, the size of the air outlet and the torsion and rotation speed of the hollow disc can be controlled, thereby adjusting the spraying thickness of the anti-corrosion layer; saving materials: the use of atomized anti-corrosion agents can greatly save material consumption; wide range of application: this scheme can be applied to the spraying of anti-corrosion layers on the inner walls of pipes of different shapes such as hoses.

[0030] (3) The mobile spraying mechanism of the present invention has a longer outer end of the fixed arc panel than the outer end of the flexible arc panel. When the air from the air outlet is blown out on the outer convex arc surface of the fixed arc panel, a Coanda effect is formed. The Coanda effect is a phenomenon in fluid mechanics, which refers to the fact that when a high-speed fluid flows along a solid surface, a low-pressure area is generated on the surface, allowing the fluid to adhere tightly to the surface, thereby forming a stable boundary layer. In this scheme, the existence of the Coanda effect can make the spraying agent adhere to the inner wall of the hose more evenly, thereby improving the spraying effect and quality of the anti-corrosion layer. The inverse piezoelectric effect is applied to the flexible arc panel. By applying an electric field to control the elongation or shortening of the piezoelectric ceramic plate, the bending degree of the flexible arc panel can be controlled, thereby adjusting the volume of the air outlet and the cross-sectional area at the outlet. In this way, the amount of spraying and the range of spraying can be adjusted as needed, thereby improving the accuracy and efficiency of spraying. The application of this inverse piezoelectric effect makes the spraying process more precise and more controllable, thereby improving the efficiency and quality of spraying.

[0047] Wherein, the outer anti-UV film is polycarbonate, polyurethane, polyethylene or fluorocarbon film.

[0048] Wherein, the inner transparent film is a polyester film, a polypropylene film or a polyethylene film.

[0049] The anti-corrosion light-curing hose further comprises an anti-corrosion layer which is sprayed on the inner wall after being constructed on site and cured by ultraviolet light; the anti-corrosion layer comprises:

[0065] In the above embodiment, a variety of formula combinations are selected within the formula range to prepare the anti-corrosion layer, and the test is carried out after UV curing, wherein epoxy resin: EP828 (domestic), fluorocarbon polymer: FM-1 (imported), filler: quartz powder, solvent: ethylene oxide, photoinitiator: benzoyl diethyl carbamate (imported); salt spray corrosion resistance test conditions: salt spray test time is 200 hours, according to GB / T 1771-2007 standard test; wear resistance test conditions: grinding wheel wear method is adopted, according to GB / T 1768-2006 standard test. The test results are summarized as follows:

[0066]

[0067] It can be seen from the test structure that the anti-corrosion layers prepared within the formulation range have good corrosion resistance and wear resistance.

[0068] In addition, refer to Figures 1 to 3The anti-corrosion layer is sprayed by a mobile spraying mechanism, which is detachably mounted outside the front and rear ends of the middle part of the walking robot in a tube, and a plurality of ultraviolet curing lamps 4 are arranged on the periphery of the middle part of the walking robot in the tube; the mobile spraying mechanism is detachably sleeved outside the front and rear ends of the middle part of the walking robot; the mobile spraying mechanism is rotatably sleeved between the front and rear ends of the middle part of the walking robot; the mobile spraying mechanism includes a hollow disc 701; the center of the hollow disc 701 is rotatably sleeved on the protruding parts of the front and rear ends of the middle part of the walking robot, and The front and rear parts of the sleeve are respectively provided with bearings 702; the front and rear parts of the bearing 702 are also provided with sealing baffles 703; the sealing baffle 703 is also embedded with a sealing ring 704 which is sleeved on the outer circumferential surface of the protruding parts at the front and rear ends of the middle part of the walking robot; the outer ring of the hollow disc 701 is fixedly provided with multiple groups of spray guides 705; the spray guides 705 include a clockwise inclined cyclone nozzle 706 and a counterclockwise inclined cyclone nozzle 707; the inclination angles of the clockwise inclined cyclone nozzle 706 and the counterclockwise inclined cyclone nozzle 707 are different; the clockwise inclined cyclone nozzle 706 and the counterclockwise inclined cyclone nozzle 707 are different; The inclined cyclone nozzle 706 and the counterclockwise inclined cyclone nozzle 707 respectively include a fixed arc panel 708 and a flexible arc panel 709; the convex arc surface of the fixed arc panel 708 and the flexible arc panel 709 enclose an air outlet 710 whose cross-sectional area gradually decreases outward; a narrow air outlet gap is formed at the outlet of the air outlet 710; the outer end of the fixed arc panel 708 is longer than the outer end of the flexible arc panel 709, so that the air outlet from the air outlet 710 adheres to the convex arc surface of the fixed arc panel 708 under the Coanda effect and is blown out; the flexible arc panel 709 The elastic plate is made of elastic material, and a piezoelectric deformation plate 711 is fixedly attached to the back side of the elastic plate; the piezoelectric deformation plate 711 includes an elastic resin plate 712 and piezoelectric ceramic plates 713 attached to both sides of the elastic resin plate 712; by applying an electric field to the two piezoelectric ceramic plates 713 respectively through an external circuit, the piezoelectric ceramic plates 713 can be controlled to extend or shorten one of them, thereby controlling the bending degree of the piezoelectric deformation plate 711, thereby controlling the bending degree of the flexible arc panel 709, thereby controlling the volume of the air outlet duct 710 and the cross-sectional area at the outlet.

[0069] An external pump air pipe pumps atomized anti-corrosion agent into the hollow disc 701; after the atomized air is further pressurized in the hollow disc 701, it is blown out through the air outlet duct 710. Since the clockwise inclined cyclone nozzle 706 and the counterclockwise inclined cyclone nozzle 707 have different inclination directions and degrees, a part of the torque generated by the blown air on the hollow disc 701 can be neutralized, thereby ensuring that the blown atomized air can evenly spray the anti-corrosion agent on the inner wall of the cured hose; and by respectively adjusting the size of the air outlet duct 710 of the clockwise inclined cyclone nozzle 706 and the counterclockwise inclined cyclone nozzle 707, the size of the air outlet as well as the torque and rotation speed of the hollow disc 701 can be controlled, thereby adjusting the spray thickness of the anti-corrosion layer.

[0070] Advantages of this program include:

[0071] 1. High degree of automation: The walking robot is used for spraying operation, and the mobile spraying mechanism has a high degree of automation, which can greatly reduce manual operation and improve work efficiency.

[0072] 2. Uniform spraying: Due to the use of clockwise and counterclockwise inclined cyclone nozzles, part of the torque generated by the blown air on the hollow disc can be neutralized, thereby ensuring uniform spraying.

[0073] 3. Adjustable spray thickness: By adjusting the size of the air outlet of the clockwise inclined cyclone nozzle and the counterclockwise inclined cyclone nozzle, the size of the air outlet as well as the torque and rotation speed of the hollow disc can be controlled, thereby adjusting the spray thickness of the anti-corrosion layer.

[0074] 4. Save materials: The use of atomized anti-corrosion agents can greatly save material usage.

[0075] 5. Wide range of applications: This solution can be applied to the spraying of anti-corrosion layers on the inner walls of pipes of different shapes, such as hoses.

[0076] Among them, since the outer end of the fixed arc panel 708 is longer than the outer end of the bendable arc panel 709, when the air outlet of the air outlet 710 blows out on the outer convex arc surface of the fixed arc panel 708, a Coanda effect will be formed. The Coanda effect is a phenomenon in fluid mechanics, which means that when a high-speed flowing fluid flows along a solid surface, a low-pressure area will be generated on the surface, allowing the fluid to adhere tightly to the surface, thereby forming a stable boundary layer. In this solution, the existence of the Coanda effect can make the spraying agent adhere to the inner wall of the hose more evenly, thereby improving the spraying effect and quality of the anti-corrosion layer.

[0077] The inverse piezoelectric effect is applied to the bendable arc panel. By applying an electric field to control the elongation or shortening of the piezoelectric ceramic plate, the degree of bending of the bendable arc panel can be controlled, thereby adjusting the volume of the air outlet and the size of the cross-sectional area at the outlet. In this way, the amount and range of spraying can be adjusted as needed, thereby improving the accuracy and efficiency of spraying. The application of this inverse piezoelectric effect makes the spraying process more precise and more controllable, thereby improving the efficiency and quality of spraying.

[0078] In addition, refer to Figure 4 -13: The robot walking inside the tube includes:

[0079] Connecting tube 1;

[0080] The supporting and moving mechanism 2 is arranged on both sides of the connecting tube 1. The supporting and moving mechanism 2 includes a bidirectional threaded rod 201, a first forward and reverse motor 202 and two groups of supporting components. The bidirectional threaded rod 201 is rotatably embedded on both sides of the outer wall of the connecting tube 1, and one end of the bidirectional threaded rod 201 is fixedly arranged on the output end of the first forward and reverse motor 202. Each group of supporting components is arranged on the bidirectional threaded rod 201;

[0081] The adjusting mechanism 3 is arranged in the connecting tube 1. The adjusting mechanism 3 includes a driving component, a cam component, six pushing frames 301 and six mounting frames 302. The driving component is arranged in the connecting tube 1, and the cam component is arranged on the driving component. Each pushing frame 301 slides equidistantly along the circumferential direction and penetrates the outer wall of the connecting tube 1. Each mounting frame 302 is fixedly arranged on the top of the outer wall of the pushing frame 301.

[0082] There are six ultraviolet curing lamps 4, each of which is rotatably embedded on both sides of the inner wall of the mounting frame 302; and

[0083] The cleaning mechanism 5 is provided with a plurality of groups, each group of cleaning mechanisms 5 is arranged on the mounting frame 302, each group of cleaning mechanisms 5 includes a cleaning component, a rotating component and a cleaning cotton block 501, the cleaning component is arranged in the mounting frame 302, the rotating component is arranged on the mounting frame 302, and the cleaning cotton block 501 is arranged on the cleaning component.

[0084] In this embodiment: the first forward and reverse motor 202 is arranged on one of the groups of supporting components. When the first forward and reverse motor 202 is powered on, it drives the bidirectional threaded rod 201 to rotate on the connecting tube 1, and can drive the two supporting components to open and close, so as to adapt to hoses of different diameters and make them move in the light-curing hose. The driving component in the adjustment mechanism 3 drives the cam component to synchronously drive each pushing frame 301 and the mounting frame 302 to move, and can synchronously adjust the distance between each ultraviolet curing lamp 4 and the tube wall to meet the curing requirements of the curing hose, prevent the ultraviolet curing lamp 4 from being too far away from the tube wall to cause light attenuation or the lamp from being too close to the tube wall to cause dark areas. Since the two groups of supporting components are symmetrically arranged on both sides of the connecting tube 1, the light of the ultraviolet curing lamp 4 can be effectively prevented from being blocked, thereby reducing the hose. In order to improve the curing effect, the mounting frame 302 is used for installing and placing the UV curing lamp 4. The shape of the UV curing lamp 4 is cylindrical, which prevents the light of the plate-shaped UV curing lamp 4 from being unable to fully irradiate the inner wall of the light curing hose, making it difficult to fully cure the light curing hose. The surface of the UV curing lamp 4 can be cleaned by the cleaning mechanism 5 to keep the UV curing lamp 4 clean and transparent, and to prevent dust or stains from adhering to the surface of the UV curing lamp 4, which affects the penetration of ultraviolet rays and causes incomplete curing of the light curing hose. The cleaning component can be used to soak the cleaning cotton block 501 to improve the cleaning effect. The rotating component can be used to drive the UV curing lamp 4 to rotate, so that the cleaning cotton block 501 can fully clean the surface of the UV curing lamp 4. Gauze is provided on the cleaning cotton block 501.

[0085] Specifically, each group of supporting components includes a moving part 203, a placement frame 204 and three groups of supporting components. The moving part 203 is threadedly connected to the outer wall of the bidirectional threaded rod 201, and the placement frame 204 is fixedly arranged on one side of the outer wall of the connecting tube 1. Each group of supporting components is equidistantly arranged on the moving part 203 along the circumferential direction. The first forward and reverse motor 202 is installed on one side of the outer wall of the placement frame 204 by bolts, and the bidirectional threaded rod 201 is rotatably embedded in one side of the outer wall of the placement frame 204.

[0086] In this embodiment: as the bidirectional threaded rod 201 rotates between the two placement racks 204, it can drive the two moving parts 203 to move closer to or away from each other, so that each group of support components is located around the inner wall of the light-curing hose, and the moving part 203 and the placement rack 204 slide together to guide the movement of the moving part 203.

[0087] Specifically, each group of support components includes a fixing part 205, a support rod 206, a connecting rod 207, a connecting part 208 and a moving wheel 209. The fixing part 205 is fixedly arranged on one side of the outer wall of the connecting tube 1, one end of the support rod 206 is movably mounted on the inner wall of the fixing part 205, the connecting part 208 is fixedly arranged on one side of the outer wall of the support rod 206, the moving wheel 209 is installed on one end of the support rod 206 by bolts, one end of the connecting rod 207 is movably mounted on the inner wall of the connecting part 208, and the other end of the connecting rod 207 is movably mounted on the outer wall of the moving part 203.

[0088] In this embodiment: the fixing member 205 is used for installing and placing the support rod 206, and the moving wheel 209 provided on the support rod 206 facilitates the movement of the light-curing robot in the light-curing hose. The connecting member 208 and the connecting rod 207 can connect the support rod 206 and the moving member 203 together, and can drive the connecting rod 207 to pull the support rod 206 to rotate on the fixing member 205 as the moving member 203 moves, so as to adapt to hoses of different diameters.

[0089] Specifically, the driving component includes a fixed cylinder 303, a worm 304 and a second forward and reverse motor 305. The fixed cylinder 303 is fixedly arranged on the inner wall of the connecting cylinder 1. The second forward and reverse motor 305 is installed on one side of the inner wall of the connecting cylinder 1 by bolts. The worm 304 is fixedly arranged on the output end of the second forward and reverse motor 305.

[0090] In this embodiment: the fixed cylinder 303 wraps the outer wall of the bidirectional threaded rod 201 to play an isolating role and facilitate the installation and placement of the cam component. The second forward and reverse motor 305 drives the worm 304 to rotate when powered on, which is used to drive the cam component, so that the cam component drives each pushing frame 301 and the mounting frame 302 to move synchronously at equal distances, so that the ultraviolet curing lamps 4 are evenly distributed in the central area of ​​the pipeline, and can evenly irradiate the inner wall of the light-curing hose.

[0091] Specifically, the cam component includes a worm wheel 306, a circular plate 307 and six groups of cam assemblies. The circular plate 307 is movably mounted on the outer wall of the fixed cylinder 303, the worm wheel 306 is fixedly mounted on the outer wall of the circular plate 307, and the worm wheel 306 is meshed with the worm 304. Each group of cam assemblies is equidistantly arranged on the circular plate 307 along the circumferential direction.

[0092] In this embodiment, the worm wheel 306 is meshed with the worm 304 , and as the worm 304 rotates, the worm wheel 306 can drive the circular plate 307 to rotate on the fixed cylinder 303 , thereby synchronously driving each group of cam assemblies.

[0093] Specifically, each cam assembly includes a cam hole 308 and a push shaft 309. The cam hole 308 is opened on one side of the outer wall of the circular plate 307. The push shaft 309 is fixedly arranged on one side of the outer wall of the push frame 301 near the bottom edge, and the push shaft 309 is slidably embedded in the inner wall of the cam hole 308.

[0094] In this embodiment: as the circular plate 307 rotates, the position of the cam hole 308 can be changed, and the cam hole 308 drives the driving shaft 309 to move. Since the driving frame 301 slides through the inner wall of the connecting tube 1, it can limit the movement of the driving frame 301, drive each mounting frame 302 to move synchronously, so that the ultraviolet curing lamps 4 are evenly distributed in the central area of ​​the pipeline, and can evenly irradiate the inner wall of the light-curing hose.

[0095] Specifically, each group of cleaning components includes a mounting frame 502, a telescopic cylinder 503 and a cleaning assembly. The mounting frame 502 is slidably embedded in both sides of the inner wall of the mounting frame 302, and the telescopic cylinder 503 is installed on one side of the outer wall of the mounting frame 302 by bolts. The mounting frame 502 is fixedly set at the output end of the telescopic cylinder 503, the cleaning cotton block 501 is slidably embedded in the inner wall of the mounting frame 502, and the cleaning assembly is arranged on the mounting frame 302.

[0096] In this embodiment: the installation frame 502 is used to install and place the cleaning cotton block 501. The installation frame 502 is driven by the telescopic cylinder 503 to move on the installation frame 302, so that the cleaning cotton block 501 is close to and attached to the surface of the ultraviolet curing lamp 4. In conjunction with the rotating parts, the surface of the ultraviolet curing lamp 4 can be fully cleaned to keep the ultraviolet curing lamp 4 clean and transparent, and to avoid dust or stains adhering to the surface of the ultraviolet curing lamp 4, which affects the penetration of ultraviolet rays and causes incomplete curing of the light curing hose.

[0097] Specifically, each group of cleaning components includes a cleaning pipe 504, a water pump 505, a cleaning cylinder 506 and a plurality of cleaning holes 507. The cleaning pipe 504 is fixedly arranged at the bottom of the inner wall of the mounting frame 502, the cleaning cylinder 506 is installed at the top of the outer wall of the mounting frame 502, the water pump 505 is connected to one side of the outer wall of the cleaning cylinder 506, the cleaning pipe 504 is connected to the output end of the water pump 505, and each cleaning hole 507 is equidistantly opened on one side of the outer wall of the cleaning pipe 504 in the horizontal direction.

[0098] In this embodiment: one end of the cleaning tube 504 passes through the installation frame 502 and is fixedly connected to the water pump 505. The ethanol solution is placed through the cleaning tube 504. The water pump 505 is installed on the top of the outer wall of the installation frame 502 and is connected to the cleaning cylinder 506 through a pipeline. The ethanol solution in the cleaning cylinder 506 is introduced into the cleaning tube 504 through the water pump 505, and enters the cleaning cotton block 501 through the cleaning hole 507 to wet the cleaning cotton block 501, thereby improving the cleaning effect of the UV curing lamp 4. The UV curing lamp 4 wiped with ethanol can be dried quickly without leaving water marks. The cleaning cotton block 501 is wrapped and arranged on the top of the outer wall of the cleaning tube 504. A fixing block is fixedly arranged at one end of the cleaning cotton block 501. The fixing block is connected to one side of the outer wall of the installation frame 502 by bolts, and the cleaning cotton block 501 is replaced.

[0099] Specifically, each set of rotating parts includes a rotating motor 508, a small gear 509 and a large gear 510. The rotating motor 508 is installed on one side of the outer wall of the mounting frame 302 by bolts. The small gear 509 is fixedly sleeved on the output end of the rotating motor 508. The large gear 510 is fixedly sleeved on one side of the outer wall of the UV curing lamp 4, and the large gear 510 and the small gear 509 are meshed with each other.

[0100] In this embodiment, the rotating motor 508 drives the small gear 509 when powered on. Since the small gear 509 is meshed with the large gear 510, the large gear 510 can be driven to drive the ultraviolet curing lamp 4 to rotate in the mounting frame 302, so that the cleaning cotton block 501 can fully clean the surface of the ultraviolet curing lamp 4. The power of the rotating motor 508, the water pump 505, the telescopic cylinder 503, the second forward and reverse motor 305 and the first forward and reverse motor 202 comes from an external power supply, which should be electrically connected to the external power supply. The internal circuit principle structure belongs to the common knowledge of technicians in this field, and will not be described in detail here. The model can be selected according to actual use.

[0101] Specifically, a limiting frame 6 is fixedly provided on the inner wall of the connecting tube 1 , and each pushing frame 301 is slidably embedded in the inner wall of the limiting frame 6 .

[0102] In this embodiment, the limiting frame 6 can play a limiting and guiding role in the movement of each pushing frame 301 and increase the stability of the movement of the pushing frame 301.

[0103] When in use, according to the inner diameter of the light-curing hose, the first forward and reverse motor 202 is driven to drive the bidirectional threaded rod 201 to rotate on the connecting tube 1, so that the two moving parts 203 are moved closer to or farther away from each other, and the connecting rod 207 is driven to pull the support rod 206 to rotate on the fixing part 205, so that the moving wheel 209 is located on the inner wall of the light-curing hose, which is convenient for the light-curing robot to move. Then, the worm 304 is driven to rotate by the second forward and reverse motor 305. The worm wheel 306 is meshed with the worm wheel 304, which can drive the worm wheel 306 to drive the circular plate 307 to rotate on the fixing tube 303, and the position of the cam hole 308 can be changed, so that the cam hole 308 drives the driving shaft 309 to move, and drives each driving frame 301 to move synchronously with the mounting frame 302, so that the ultraviolet curing lamps 4 are evenly distributed in the central area of ​​the pipeline, and the light can be evenly irradiated. The inner wall of the curing hose is surrounded and the light curing hose is cured. Before curing, the surface of the ultraviolet curing lamp 4 needs to be cleaned. The ethanol solution in the cleaning cylinder 506 is introduced into the cleaning tube 504 through the water pump 505, and enters the cleaning cotton block 501 through the cleaning hole 507 to wet the cleaning cotton block 501. Then the telescopic cylinder 503 is started to drive the mounting frame 502 to move on the mounting frame 302, so that the cleaning cotton block 501 is close to and attached to the surface of the ultraviolet curing lamp 4, and the rotating motor 508 is started to drive the small gear 509. The small gear 509 is meshed with the large gear 510, and the large gear 510 is driven to drive the ultraviolet curing lamp 4 to rotate in the mounting frame 302, so that the cleaning cotton block 501 can fully clean the surface of the ultraviolet curing lamp 4 to keep the ultraviolet curing lamp 4 clean and transparent.

[0104] The robot walking in the tube can increase the irradiation range and improve the curing effect through the cylindrical UV curing lamp. The cleaning cotton block is soaked by the cleaning component, and the rotating component drives the UV curing lamp to rotate on the mounting frame, so that the cleaning cotton block can fully clean the surface of the UV curing lamp, keep the UV curing lamp clean and transparent, and avoid dust or stains on the surface of the UV curing lamp, which will affect the penetration of ultraviolet rays and cause incomplete curing of the light-curing hose.

[0105] The walking robot in the pipe drives the cam component through the driving component in the adjustment mechanism to synchronously drive each pushing frame and the mounting frame to move, and can synchronously adjust the distance between each UV curing lamp and the pipe wall to meet the curing requirements of the curing hose, prevent the UV curing lamp from being too far away from the pipe wall to cause light attenuation or the lamp from being too close to the pipe wall to cause dark areas, thereby reducing the fixing effect.

[0106] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
