Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, specifically a UV curing device for pipeline repair. Background Technology

[0002] UV pipeline repair is one of the most commonly used technologies in the current pipeline repair field, mainly applied to the repair of damage and leakage in various pipelines such as municipal drainage and industrial transportation. Its core logic is to introduce a repair medium with light-curing properties (such as light-curing resin rolls, resin mortars, etc.) into the pipeline to be repaired, and then use the ultraviolet light provided by the UV curing device to cure the repair medium into a solidified repair layer that adheres tightly to the original pipeline and has a stable structure, thereby restoring the pipeline's transportation function and structural strength.

[0003] UV pipeline repair relies on the ultraviolet rays emitted by the UV lamps in the UV curing device to penetrate the surface of the repair medium or a specific transparent carrier, stimulating the photoinitiator inside the repair medium and causing it to rapidly undergo a cross-linking polymerization reaction, transforming from a liquid or semi-liquid state into a solid state, ultimately forming a cured layer with corrosion resistance and impact resistance. This process boasts high curing efficiency and stable molding quality, making it the core supporting element of UV pipeline repair technology.

[0004] UV curing devices primarily use UV lamps to emit ultraviolet light, which cures the repair medium for pipeline repair. Existing UV curing devices come in two forms: one where the UV lamp is installed inside a quartz glass or other cover that does not affect ultraviolet light emission, and the other where the UV lamp is directly exposed. Both types of UV lamps are easily covered by contaminants and dust when not in use (during daily storage and transportation), leading to wear and tear, damage to the UV lamp, or surface abrasion and dirt. This results in reduced light transmittance, decreased ultraviolet emission, and consequently, reduced curing efficiency. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a UV curing device for pipeline repair to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a UV curing device for pipe repair, comprising a device body, two protective covers fitted around the outside of the device body, and buffer pads connected to the inner rings of the two protective covers, a limit bolt connecting the two protective covers, eight expansion plates fixed on both sides of the two protective covers, and baffles connected inside the two expansion plates, torsion springs connecting the two baffles and the two expansion plates, and sealing gaskets connected to one side of the two baffles.

[0007] By adopting the above technical solutions, the protective cover can shield the UV lamp when it is not in operation, reducing the adhesion of dust and contaminants and the wear and tear from impacts; the buffer pad can fill the gap between the protective cover and the UV lamp, further reducing the risk of wear; the limiting bolts can fix the protective cover in place, ensuring the stability of the shielding; the extension plate can assist in limiting the protective cover and prevent it from rotating or shifting; the baffle and torsion spring can adaptively switch according to the connection status of the wiring port, achieving a balance between shielding the wiring port and avoiding cable deviation; the sealing gasket fills the gap between the baffle and the wiring port, improving the anti-contamination effect of the wiring port. The synergistic effect of all components comprehensively solves the protection defects of the UV lamp and wiring port in the existing device.

[0008] Furthermore, the buffer pad is made of closed-cell EPDM sponge rubber, and the buffer pad is fixedly connected to the protective cover by bonding with EPDM special primer and two-component polyurethane adhesive. The sealing gasket is made of EPDM rubber material, and the sealing gasket is fixedly connected to the baffle by bonding with EPDM special primer and two-component polyurethane adhesive.

[0009] By adopting the above technical solutions, closed-cell EPDM sponge rubber has excellent cushioning elasticity and resistance to compression deformation, which can effectively absorb the impact during transportation and storage, and prevent UV lamps from being damaged by bumps; EPDM rubber has good sealing performance and aging resistance, and can maintain the anti-contamination effect of the wiring port for a long time; the combination of EPDM special primer and two-component polyurethane adhesive can ensure that the buffer pad and sealing pad form a firm connection with the protective cover and baffle respectively, preventing them from falling off during long-term use and ensuring the stable performance of the protective function.

[0010] Furthermore, the protective cover, extension plate, and baffle are all made of ABS material.

[0011] By adopting the above technical solutions, ABS material has the characteristics of high strength, impact resistance, chemical corrosion resistance and easy processing, and can adapt to complex environments such as collisions and humidity that may occur in pipeline repair scenarios. At the same time, the structural stability of the material can ensure that the protective cover, extension plate and baffle are not easily deformed during long-term use, avoiding problems such as incomplete UV lamp shielding and connection port sealing failure caused by component deformation, thus improving the overall durability of the device.

[0012] Furthermore, the two protective covers are detachably connected by limiting bolts.

[0013] By adopting the above technical solution, when the device enters the working state, the limiting bolts can be removed and the protective cover can be taken off to avoid blocking the UV lamp irradiation path and ensure that the ultraviolet rays act normally on the repair medium; when not in the working state, the protective cover can be reassembled and fixed with the limiting bolts, and the device can be quickly switched to the protection mode, taking into account both work efficiency and protection needs.

[0014] Furthermore, the device body is equipped with multiple UV lamps on its outer ring, and the multiple UV lamps are distributed in a ring array. Wiring ports are installed on the outer surface and back of the device body.

[0015] By adopting the above technical solution, the ring array distribution of UV lamps can ensure that ultraviolet rays uniformly cover the outer periphery of the device body, ensuring that the repair medium on the inner wall of the pipe to be repaired can receive ultraviolet rays from all directions, avoiding differences in curing effect due to uneven irradiation; the wiring ports on the outer surface and back of the device body can be flexibly connected to external power supply and control lines to provide stable power supply for UV lamps, while meeting the wiring requirements in different scenarios and ensuring normal operation of the device.

[0016] Furthermore, the main body of the device is connected to rollers on both sides, and there are eight rollers in total, four in a group, divided into two groups. The rollers in the two groups are symmetrically distributed, and the four rollers in each group are arranged in a circular array.

[0017] By adopting the above technical solution, two sets of symmetrical and circularly arrayed rollers enable the device to move smoothly inside the pipe to be repaired, reducing shaking during movement; the setting of eight rollers further improves the contact stability between the device and the inner wall of the pipe, making it easier for staff to adjust the irradiation position of the UV lamp, ensuring that the damaged area of ​​the pipe is covered by ultraviolet light, and improving repair efficiency and quality.

[0018] Furthermore, the spacing between the extension plates is greater than the width of the roller.

[0019] By adopting the above technical solution, the gap between the expansion plates can be precisely matched with the roller area of ​​the main body of the device, so that the roller can be embedded in the gap of the expansion plates, forming an axial limit on the protective cover, effectively preventing the protective cover from rotating around the main body of the device during storage, transportation or device movement, and reducing structural wear.

[0020] Furthermore, bolts penetrate the outer surfaces of both of the expansion plates, and two bearings are provided inside each of the two baffles. The two baffles, two torsion springs, and four bearings are sleeved on the outside of the two bolts, and the baffles are rotatably connected to the bolts through the bearings. The baffles are detachably connected to the expansion plates through the bolts.

[0021] By adopting the above technical solution, the bearing setting can prevent the bolts from rotating synchronously when the baffle rotates, ensuring that the baffle opens and closes smoothly without jamming; the detachable connection between the baffle and the expansion plate facilitates quick disassembly and replacement of parts when the baffle, gasket, or torsion spring is damaged, without the need to completely disassemble the protective cover, reducing maintenance difficulty and cost, and improving the ease of use of the device.

[0022] Furthermore, multiple reinforcing ribs are connected between the eight expansion plates and the two protective covers, and the reinforcing ribs are made of ABS material. The protective covers, expansion plates, and reinforcing ribs are fixedly connected by integral molding.

[0023] By adopting the above technical solutions, the ABS reinforcing ribs can enhance the strength of the expansion plate and the protective cover, disperse the force on the expansion plate, and prevent the expansion plate from deforming or falling off due to external impact or vibration during long-term use; the one-piece molding connection method makes the protective cover, expansion plate and reinforcing ribs form a stable overall structure, improve the overall structural stability of the device, ensure that each protective component maintains its function for a long time, and extend the service life of the device.

[0024] In summary, the present invention has the following main advantages: 1. This utility model, through the setting of protective covers, buffer pads, and limiting bolts, allows two protective covers to be disassembled and assembled with the help of limiting bolts and fitted onto the outside of the main body of the device. It can effectively shield the area where the UV lamp is located when the device is not in operation, reducing the phenomenon of dust, pollutants, etc. adhering to the surface of the UV lamp. At the same time, the buffer pad in the inner ring of the protective cover can fill the gap between the protective cover and the UV lamp, reducing the risk of wear and tear on the UV lamp caused by bumps and friction during transportation or storage. It also reduces the problem of reduced light transmittance and reduced curing efficiency of the UV lamp due to damage or surface dirt when it is not in operation. 2. This utility model, through the setting of extension plates, has eight extension plates fixed on both sides of the two protective covers, and the distance between the extension plates is greater than the width of the rollers. The gap can precisely correspond to the roller area of ​​the main body of the device, thereby limiting the protective covers and preventing the protective covers from rotating around the main body of the device when stored, transported or idle; thus improving structural stability. 3. This utility model, through the arrangement of a baffle, torsion spring, and sealing gasket, allows the torsion spring between the baffle and the expansion plate to adaptively adjust according to the cable connection status of the connection port: when the connection port is still connected to a cable, the baffle can be pushed and rotated to open by the cable, thus avoiding the cable; when the connection port is not connected to a cable, the torsion spring can drive the baffle to rotate to the closed state, forming a shield for the end of the connection port, reducing the phenomenon of dust and impurities entering the interior of the connection port; at the same time, the sealing gasket on one side of the baffle can fill the gap between the baffle and the end face of the connection port, further improving the sealing performance, reducing the risk of contact failure caused by the accumulation of contaminants in the connection port, and improving the anti-pollution effect.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure. Example 1:

[0029] A UV curing device for pipe repair, such as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the device includes a main body 1, with two protective covers 5 fitted onto the outside. Each protective cover 5 has an inner ring with a buffer pad 6 made of closed-cell EPDM sponge rubber. The buffer pad 6 is fixedly connected to the protective cover 5 by adhesive using EPDM primer and a two-component polyurethane adhesive. A limiting bolt 7 connects the two protective covers 5, allowing them to be disassembled and reconnected. When the operator places the two protective covers 5 over the main body 1, the limiting bolt 7 secures them, ensuring complete shielding of the area where the UV lamp 2 is located, thus reducing the UV lamp's temperature. This reduces the amount of dust and contaminants adhering to the surface of the UV lamp 2. Simultaneously, the inner ring of the protective cover 5, secured with a closed-cell EPDM sponge rubber cushioning pad 6 by a special EPDM primer and a two-component polyurethane adhesive, fills the gap between the protective cover 5 and the UV lamp 2, reducing the impact transmitted by bumps during transportation or storage. Eight extension plates 8 are fixed to both sides of the two protective covers 5. The distance between the extension plates 8 is greater than the width of the rollers 3. During the assembly of the protective cover 5, because the distance between the extension plates 8 is greater than the width of the rollers 3, the gap between the extension plates 8 can interact with the rollers 3 of the main body 1. The precise domain correspondence provides a limiting effect on the protective cover 5, preventing it from rotating around the main body 1 during storage, transportation, or idleness, thus reducing structural wear. Each of the two extension plates 8 has a baffle 10 connected internally. The protective cover 5, extension plates 8, and baffles 10 are all made of ABS material. Torsion springs 11 connect the two baffles 10 to the two extension plates 8. A sealing gasket 12 is connected to one side of each baffle 10. The sealing gasket 12 is made of EPDM rubber and is fixedly connected to the baffle 10 by bonding with EPDM primer and a two-component polyurethane adhesive. When a cable is still connected to the connection port 4, the baffle 10 will be pushed by the cable or opened manually by the staff to avoid the cable and not affect the cable connection. If no cable is connected to the connection port 4, the torsion spring 11 will drive the baffle 10 to rotate to the closed state, forming a shield on the end of the connection port 4 and reducing the phenomenon of dust and impurities entering the interior of the connection port 4. In addition, the EPDM rubber sealing gasket 12, which is fixedly connected to the baffle 10 by EPDM special primer and two-component polyurethane adhesive, can fill the gap between the baffle 10 and the end face of the connection port 4, further improving the sealing performance and reducing the risk of contact failure caused by the accumulation of contaminants in the connection port 4.

[0030] See Figure 1 and Figure 2In the above embodiment, multiple UV lamps 2 are installed on the outer ring of the device body 1. The multiple UV lamps 2 are arranged in a ring array. After the UV lamps 2 are powered on, they emit ultraviolet rays. The ultraviolet rays can irradiate the surface of the repair medium, stimulate the photoinitiator inside the repair medium, and promote the curing of the repair medium to form a cured layer with corrosion resistance and impact resistance, thereby realizing pipeline repair. The outer surface and back of the device body 1 are equipped with wiring ports 4. The wiring ports 4 on the outer surface and back of the device body 1 are connected to external cables to power the UV lamps 2 arranged in a ring array on the outer ring of the device body 1. Rollers 3 are connected to both sides of the device body 1. There are eight rollers 3, four in a group, divided into two groups. The two groups of rollers 3 are symmetrically distributed. The four rollers 3 in each group are arranged in a ring array. The rollers 3 on both sides of the device body 1 can help the device move stably inside the pipeline to be repaired, and facilitate the adjustment of the irradiation position of the UV lamps 2. Example 2:

[0031] Based on the above embodiment one, the following settings are made to facilitate structural replacement.

[0032] See Figure 1 , Figure 3 , Figure 4 and Figure 5 In the above embodiment, bolts penetrate the outer surfaces of both expansion plates 8, and two bearings are provided inside each of the two baffles 10. The two baffles 10, two torsion springs 11, and four bearings are sleeved on the outside of the two bolts. The baffles 10 are rotatably connected to the bolts through the bearings, and the baffles 10 are detachably connected to the expansion plates 8 through the bolts. Because the bearings inside the baffles 10 are sleeved on the bolts penetrating the expansion plates 8, the bearings can avoid driving the bolts to rotate synchronously when the baffles 10 are rotated, ensuring the smoothness of the rotation adjustment of the baffles 10. At the same time, the baffles 10 are detachably connected to the expansion plates 8 through the bolts. By simply unscrewing the bolts, the baffles 10, torsion springs 11, and bearings can be removed from the expansion plates 8. After replacing the new parts, the new parts are sleeved on the outside of the bolts and the bolts are tightened to complete the assembly, realizing the convenient replacement of vulnerable parts. Example 3:

[0033] Based on the above embodiment one, the following settings are now adopted to increase structural strength.

[0034] See Figure 1 , Figure 3 and Figure 4 In the above embodiment, a plurality of reinforcing ribs 9 are connected between the eight expansion plates 8 and the two protective covers 5. The reinforcing ribs 9 are made of ABS material. The protective covers 5, expansion plates 8 and reinforcing ribs 9 are fixedly connected by integral molding to increase the structural strength of the protective covers 5 and expansion plates 8.

[0035] The implementation principle of this utility model is as follows: First, when the device is in working condition and repairing the pipeline, the rollers 3 on both sides of the main body 1 can help the device move stably inside the pipeline to be repaired, making it easy to adjust the irradiation position of the UV lamp 2; the wiring ports 4 on the outer surface and back of the main body 1 are connected to external cables to power the UV lamps 2 arranged in a ring array on the outer ring of the main body 1. After the UV lamps 2 are powered on, they emit ultraviolet rays, which can irradiate the surface of the repair medium, stimulate the photoinitiator inside the repair medium, and promote the curing of the repair medium to form a cured layer with corrosion resistance and impact resistance, thereby realizing pipeline repair. When the device completes its repair work and enters a non-working state such as daily storage or transportation, the staff first protects the area of ​​UV lamp 2. The staff puts two protective covers 5 on the outside of the main body 1 of the device and uses limiting bolts 7 to limit the two protective covers 5, so that the protective covers 5 completely shield the area where UV lamp 2 is located, reducing the phenomenon of dust, pollutants and other substances adhering to the surface of UV lamp 2. At the same time, the inner ring of the protective cover 5 is fixed with a closed-cell EPDM sponge rubber cushioning pad 6 by EPDM special primer and two-component polyurethane adhesive, which can fill the gap between the protective cover 5 and UV lamp 2, reducing the impact force transmitted by the protective cover 5 during transportation or storage. During the assembly of the protective cover 5, since the spacing between the expansion plates 8 is greater than the width of the roller 3, the gap between the expansion plates 8 can precisely correspond to the roller 3 area of ​​the main body 1 of the device, thereby limiting the protective cover 5 and preventing the protective cover 5 from rotating around the main body 1 of the device during storage, transportation or idle time, thus reducing structural wear. Meanwhile, for the wiring port 4 of the main body 1, the baffle 10 inside the expansion plate 8 achieves adaptive adjustment through the torsion spring 11; if the wiring port 4 is still connected to a cable, the baffle 10 will be pushed by the cable or opened manually by the staff to avoid the cable and not affect the cable connection; if the wiring port 4 is not connected to a cable, the torsion spring 11 will drive the baffle 10 to rotate to the closed state, forming a shield on the end of the wiring port 4, reducing the phenomenon of dust and impurities entering the wiring port 4; and the EPDM rubber sealing gasket 12, which is fixedly connected to the baffle 10 by EPDM special primer and two-component polyurethane adhesive, can fill the gap between the baffle 10 and the end face of the wiring port 4, further improving the sealing performance and reducing the risk of contact failure caused by the accumulation of contaminants in the wiring port 4; When the baffle 10, sealing gasket 12 are damaged or the torsion spring 11 is damaged and needs to be replaced, the bearing inside the baffle 10 is connected to the bolt that passes through the extension plate 8. When the baffle 10 is rotated, the bearing can avoid driving the bolt to rotate synchronously, ensuring the smoothness of the rotation adjustment of the baffle 10. At the same time, the baffle 10 is detachably connected to the extension plate 8 by the bolt. Simply unscrew the bolt to remove the baffle 10, torsion spring 11 and bearing from the extension plate 8. After replacing the new parts, the new parts are then fitted onto the outside of the bolt and the bolt is tightened to complete the assembly, realizing the convenient replacement of vulnerable parts.
