Description

Technical Field

[0001] This invention relates to the field of inspection wells, and more particularly to a light fixture for the overall repair of inspection wells. Background Technology

[0002] Inspection wells are installed to facilitate the maintenance and installation of urban underground infrastructure. They are generally located at the intersection of pipelines. The side walls of the inspection wells are equipped with connecting pipes that communicate with each underground pipeline. When repairing inspection wells, the main focus is on repairing these connecting pipes. Ultraviolet light repair technology is a new type of trenchless pipeline repair process that has been widely used in the field of pipeline repair.

[0003] Existing pipe UV repair technology lamp holders cannot guarantee uniform UV light exposure to the inner wall of the pipe during use. This results in different UV absorption rates in different parts of the pipe, leading to varying degrees of repair and making the pipe prone to damage. In addition, existing lamp holders cannot automatically move into the pipe during repair, requiring manual adjustment after a portion of the pipe has been repaired, which is not conducive to the repair of manhole pipes. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in ensuring uniform ultraviolet light exposure to the inner wall of the pipeline, resulting in different absorption of ultraviolet light at different parts of the pipeline, which can easily lead to damage. Furthermore, the light fixture is difficult to move automatically into the pipeline during repair, which is not conducive to the repair of inspection well pipelines. Therefore, this invention proposes a light fixture for the overall repair of inspection wells.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Reference Figure 1-4A lamp holder for overall repair of inspection wells includes a support base 1. A fixing plate 2 is connected to the top of the support base 1, and the bottom end of the fixing plate 2 extends into the interior of the support base 1. The contact surface between the fixing plate 2 and the support base 1 is slidably connected, and the fixing plate 2 can slide in any direction on its contact surface with a fixing rod 3. The device is fixed by the support base 1 to facilitate the repair of pipes inside the inspection well. A fixing rod 3 is fixedly connected to one side wall of the fixing plate 2. A connecting roller 4 is rotatably sleeved on the fixing rod 3. Multiple sets of ultraviolet repair lamps 5 are fixedly connected to the outer side of the connecting roller 4. Ultraviolet light repair of pipes is a new type of trenchless pipe repair technology. By irradiating the underground pipes with ultraviolet light emitted by the ultraviolet repair lamps 5, the repaired pipes are repaired. The system generates thermo-mechanical and electrochemical effects, thereby removing the damaged lining. Multiple ultraviolet repair lamps 5 in each group are centrally symmetrically arranged about the center of the corresponding connecting roller 4 section. Therefore, when the connecting roller 4 rotates, the ultraviolet repair lamps 5 also rotate, ensuring uniform ultraviolet light irradiation of the pipe's inner wall, which is beneficial for pipe repair. Two connecting plates 15 are also provided on the fixing rod 3, located on the front and rear sides of the connecting roller 4 respectively. Each connecting plate 15 is fixedly connected to the connecting roller 4 via multiple connecting blocks 14. A driving structure is provided on the side wall of the fixing plate 2 near the connecting roller 4. The driving structure includes a rotating cylinder 6 that rotates on the side wall of the fixing plate 2. A ring is formed on the side wall of the fixing plate 2. The rotating cylinder 6 has a shaped groove. Multiple rotating blocks corresponding to the annular groove are fixedly connected to the side wall of the rotating cylinder 6. A connecting cylinder 7 is slidably connected inside the rotating cylinder 6. Multiple sliding blocks 8 are fixedly connected to the side wall of the connecting cylinder 7. A sliding groove 9 corresponding to each sliding block 8 is formed on the inner wall of the rotating cylinder 6. A drive motor 10 is fixedly mounted on the side wall of the support base 1 near the rotating cylinder 6 via a base plate. A rotating rod 11 is fixedly connected to the output end of the drive motor 10. A bevel gear 12 is fixedly connected to the other end of the rotating rod 11. A bevel gear 13 corresponding to the bevel gear 12 is fixedly fitted on the outer side of the rotating cylinder 6. The bevel gear 12 and the bevel gear 13 mesh. After the drive motor 10 is started, its output end drives the rotating cylinder 6. Rotating rod 11 rotates, causing bevel gear 12 to rotate, which in turn causes bevel gear 2 12 and the rotating cylinder 6 fixedly connected to bevel gear 2 12 to rotate, making the connecting cylinder 6 rotate as well. This causes the connecting plate 15 connected to the connecting cylinder 6 to rotate. Under the action of connecting block 14, the connecting roller 4 and the ultraviolet repair lamp 5 also rotate. The outer wall of the fixing rod 3 is provided with fine threads, and the inner side wall of the connecting cylinder 7 is also provided with corresponding threaded grooves. The fixing rod 3 and the connecting cylinder 7 are connected by threads and threaded grooves. Since the fixing rod 3 is fixed, the connecting cylinder 7 will move along the fixing rod 3 when it rotates under the action of the threads, pushing the connecting plate 15 and the connecting roller 5 to move together. The other end of the connecting cylinder 7 is fixedly connected to the side wall of the corresponding connecting plate 15.The center of the rotating cylinder 6 corresponds to the fixed rod 3. Each connecting plate 15 has a connecting cavity 16 inside. A connecting sleeve 17 is fitted onto the part of the fixed rod 3 located in the connecting cavity 16. Multiple connecting springs 19 are fixedly connected to the side wall of the connecting sleeve 17. A movable plate 18 is fixedly connected to the other end of each connecting spring 19. Multiple movable plates 18 are slidably connected between the left and right inner side walls of the connecting cavity 16. A connecting rod 20 is fixedly connected to the end of each movable plate 18 away from the fixed rod 3. Each connecting rod 20 extends through the inner wall of the corresponding connecting cavity 16 and out to the outside of the connecting plate 15. A connecting frame 21 is fixedly connected to the other end of each connecting rod 20. A rolling ball 24 is set between the left and right inner side walls of the connecting rod 20. The rolling ball 24 can move in all directions. A matching piece is set on both the left and right sides of each rolling ball 24. The device is equipped with two fixed clamps 23, each with a fixed block 22 fixedly connected to one end away from the other. The other end of each fixed block 22 is fixedly connected to the inner wall of the corresponding connecting frame 21. After the device is inserted into the pipe, the elasticity of the connecting spring 19 causes the moving plate 18 and connecting rod 20 to move outwards, allowing each rolling ball 24 to contact the inner wall of the pipe. This positions the fixed rod part in the middle of the pipe, while the two sets of connecting plates 15 ensure that the entire fixed rod 3 is located on the center line of the pipe. Therefore, the distance from each ultraviolet repair lamp 5 to the inner wall of the pipe is equal, which is beneficial for the even irradiation of the ultraviolet repair lamp 5 and for pipe repair. The surfaces of the fixed clamps 23 and the rolling balls 24 are smooth. The fixed rod 3 is a telescopic flexible rod, and a limiting block is fixedly connected to the end of the fixed rod 3 away from the fixed plate 2. The connecting roller 4 is made of soft rubber.

[0022] In this invention, when the device is in use, it is fixed by the support base 1. Then, the fixing rod 3 is inserted into the pipe to be repaired. After the device is inserted into the pipe, the elasticity of the connecting spring 19 causes the moving plate 18 and the connecting rod 20 to move outward, so that each rolling ball 24 contacts the inner wall of the pipe, placing the fixing rod part in the middle of the pipe. The two sets of connecting plates 15 ensure that the entire fixing rod 3 is located on the center line of the pipe. Therefore, the distance from each ultraviolet repair lamp 5 to the inner wall of the pipe is equal, which is beneficial for the even irradiation of the ultraviolet repair lamp 5 and for the repair of the pipe. Then, the device is activated. The ultraviolet repair lamp 5 and the drive motor 10 are activated. After the drive motor 10 is started, its output end drives the rotating rod 11 to rotate, thereby causing the first bevel gear 12 to rotate. This causes the second bevel gear 12 and the rotating cylinder 6 fixedly connected to the second bevel gear 12 to rotate, which in turn causes the connecting cylinder 6 to rotate as well. This causes the connecting plate 15 connected to the connecting cylinder 6 to rotate. Under the action of the connecting block 14, the connecting roller 4 and the ultraviolet repair lamp 5 also rotate. The ultraviolet repair lamp 5 emits ultraviolet light to irradiate the inner wall of the pipe. The ultraviolet repair lamp 5, which rotates at a uniform speed, can make the inner wall of the pipe receive uniform ultraviolet light, which is beneficial to the repair of the pipe.

[0023] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
