Description

Technical Field

[0003] Pipeline UV curing repair technology is mainly used to repair damaged parts of urban underground water pipes. Without changing the position of the target pipe, it can pull a soft liner made of glass fiber and impregnated with resin into the target pipe through mechanical traction, and then expand the soft liner through inflation until it fits tightly against the inner wall of the target pipe. Then, utilizing the property that the resin in the soft liner will cure when exposed to ultraviolet light, a UV lamp is placed in the inflated soft liner and the UV lamp is controlled to move at a certain speed in the soft liner, so that the soft liner is gradually cured from one end to the other and fits tightly against the target pipe, forming a hard "pipe in pipe" structure in the target pipe, thereby repairing the underground pipeline that has been damaged or has lost its transportation function in situ.

[0005] However, the above-mentioned related technologies have the defect that the application scope of the equipment is small. The above-mentioned related technologies are only applicable to circular pipes, and for rectangular pipes, the light cannot evenly illuminate the inner wall of the rectangular pipe, so it cannot be applied to the rectangular pipe.

[0008] By adopting the above technical scheme, the culvert adaptive UV curing lamp holder can achieve uniform UV irradiation inside circular or rectangular pipes, especially for rectangular pipes, it can effectively avoid light blind spots and ensure that all parts of the inner wall of the pipe can be fully cured; specifically, when curing and repairing a circular pipe, the rotation axis of the driving component is made coaxial with the pipe, and the driving component drives the mounting seat to rotate, so that the UV light strip rotates in the pipe, and the UV light strip emits UV light to uniformly irradiate different parts of the inner wall of the pipe; when curing and repairing a rectangular pipe, the four UV light strips are respectively parallel to the inner walls of the four rectangular pipes, the distance between the UV light strip and the inner wall of the pipe can be adjusted by adjusting the extension length of the first telescopic driving member, and the coverage length of the UV light strip irradiation can be adjusted by adjusting the extension length of the double-head telescopic driving member, thereby achieving uniform irradiation of the rectangular pipe wall.

[0011] Optionally, it also includes a detector arranged on the base, wherein the detector is used to detect the cross-sectional shape of the inner wall of the pipe, and the detector and the drive assembly are both electrically connected to the control host; when the detector detects that the cross-sectional shape of the inner wall of the pipe is circular, the control host controls the drive assembly to drive the mounting base to rotate; when the detector detects that the cross-sectional shape of the inner wall of the pipe is rectangular, the control host controls the drive assembly to stop.

[0012] By adopting the above technical scheme, the adaptive UV curing lamp holder for the culvert can automatically identify the cross-sectional shape of the inner wall of the pipe and adjust the working state according to different shapes; specifically, when the detector detects that the inner wall of the pipe is circular, the control host starts the driving assembly to rotate the mounting base to ensure that the UV light strip can evenly illuminate the entire circumference, thereby improving the curing efficiency and quality; when the detector detects that the inner wall of the pipe is rectangular, the control host stops the driving assembly to avoid unnecessary rotation that causes uneven light exposure, thereby ensuring that the UV light strip can concentrate on irradiating every corner of the rectangular pipe, thereby achieving more effective curing; this design not only improves the scope of application of the equipment, but also enhances the intelligence of the operation and improves the overall performance of the repair operation.

[0014] By adopting the above technical solution, the combination of the second telescopic drive member and the drive wheel can not only limit the rotation of the base itself and realize the smooth movement of the base in pipes of different shapes, but also adapt to pipes of different diameters by adjusting the length of the second telescopic drive member, thereby improving the adaptability and operational convenience of the equipment.

[0015] Optionally, it also includes a plurality of second distance sensors installed on the base, and the plurality of second distance sensors are used to detect the relative position between the rotation axis of the mounting seat and the central axis of the pipeline. The plurality of second distance sensors and the moving components are electrically connected to the control host. The control host can control the second telescopic drive member to adjust the position of the base in the pipeline according to the detection values ​​of the plurality of second distance sensors to ensure that the rotation axis of the mounting seat is coaxial with the central axis of the pipeline.

[0016] By adopting the above technical solution, multiple second distance sensors can monitor the relative position between the rotation axis of the mounting base and the central axis of the pipeline in real time, ensuring that the lamp holder is always in the best working state in pipelines of different shapes and sizes; the control host accurately adjusts the telescopic amount of the second telescopic drive member according to the detection results, so that the position of the base can be accurately corrected, ensuring that the irradiation path of the ultraviolet light strip in the pipeline is more uniform and stable, thereby improving the reliability and consistency of the curing effect.

[0018] By adopting the above technical solution, the device can monitor the actual light intensity of the ultraviolet light strip in real time due to the gradual attenuation of the energy of the LED lamp after the ultraviolet light strip has been used for a long time. When the light intensity decreases, the control host can automatically extend the exposure time of the ultraviolet light strip according to the data provided by the light intensity detector to ensure that the light intensity required for the curing process reaches the predetermined value and the repair quality is guaranteed. In addition, by accurately controlling the illumination time, insufficient curing due to insufficient light or material damage due to excessive light can also be avoided.

[0019] Optionally, one end of the first curved portion away from the fixed portion and one end of the second curved portion away from the fixed portion are both provided with elastic members for elastically connecting to the side wall of the double-head telescopic driving member.

[0020] By adopting the above technical solution, the elastic part can provide a pre-tightening force so that the first curved portion and the second curved portion always maintain contact with the side wall of the double-headed telescopic driving member, and a good contact state can be guaranteed even if the length of the ultraviolet light strip changes, thereby ensuring the irradiation effect of the ultraviolet light strip in pipes of different sizes.

[0021] Optionally, rollers are provided at both ends of the double-headed telescopic driving member, and the rollers are used to roll and abut against the first curved portion or the second curved portion.

[0022] By adopting the above technical solution, the ultraviolet light strip can slide smoothly during the extension and retraction process of the double-head telescopic drive member, avoiding damage or deformation of the ultraviolet light strip due to excessive friction, thereby improving the working reliability and service life of the ultraviolet light strip.

[0024] By adopting the above technical solution, the LED UV flexible light strip has the characteristics of good durability and no need for preheating. It can be started immediately and reach the required illumination, ensuring the efficiency and stability of the repair process. At the same time, due to its flexible characteristics, the light strip can be adjusted according to the actual size of the inner wall of the pipeline, ensuring that the light evenly covers the entire inner wall of the pipeline, thereby improving the curing effect.

[0025] Optionally, a chain plate structure is provided on the side of the ultraviolet light strip that contacts the double-head telescopic driving member.

[0026] By adopting the above technical solution, the setting of the chain plate structure makes the ultraviolet light strip more stable during bending and stretching, avoiding damage to the ultraviolet light strip caused by frequent bending, and extending the service life of the ultraviolet light strip.

[0027] In summary, this application includes the following beneficial technical effects: 1.
