[0042] The feedback member 73 comprises a light shield plate 731 in the shape of a circular ring and fixedly connected to the outside of the protective shell 72. The light shield plate 731 is fixedly installed around the outer edge of the lens and forms a ring-shaped light shield space to shield stray light. The outside of the light shield plate 731 is provided with a plurality of glass windows 732 as the entrance of light into the camera 7, allowing external light to pass through. The outside of the protective shell 72 is provided with a plurality of light collecting channels 733 corresponding to the positions of the glass windows 732. The apertures of the light collecting channels 733 gradually decrease from the outside to the inside to converge the incoming light, thereby enhancing the intensity and concentration of the light. The inside of the protective shell 72 is fixedly connected to a plurality of mirrors 734 located outside the light shield plate 731. The mirrors 734 are fixedly inclined at an angle of 45° to the central axis of the lens, and the angle between the axis of the mirrors 734 and the central axis of the protective shell 72 is greater than 45° and less than 90°. The mirrors 734 reflect the light converged by the light collecting channels 733 to accurately project the light onto the light receiving surface.

[0043] The transmission member 74 includes a slide rod 741, both ends of which are fixedly connected to the inner side of the protective shell 72, providing a sliding track for the counterweight 742 and limiting the movement direction of the counterweight 742. The outer side of the slide rod 741 is slidingly connected with the counterweight 742, and the contact surface of the counterweight 742 and the slide rod 741 is set as a rough surface, so as to balance the gravity of the counterweight 742 through the friction between the slide rod 741 and the counterweight 742 and the elastic force of the constant force spring 748. The front side of the counterweight 742 is fixedly connected with a light receiving plate 743, and corresponds to the reflecting mirror 734. The light receiving plate 743 selects liquid crystal elastomer as a photosensitive material, and the liquid crystal elastomer contains a large number of liquid crystal units inside. Under the irradiation of light, the molecular orientation of the liquid crystal units will change, thereby causing the size change of the material on the macroscopic. When the light intensity increases, the liquid crystal units absorb light energy, and the molecular orientation is rearranged, so that the material expands; when the light intensity decreases, the molecular orientation recovers, and the material shrinks, and the photo-induced deformation has good reversibility and stability, so that the light receiving plate 743 expands or shrinks through the change of light intensity, so as to change the friction between the counterweight 742 and the slide rod 741. The right side of the counterweight 742 is fixedly connected with a gear slot plate 744, which moves with the movement of the counterweight 742, and converts the linear motion of the counterweight 742 into the rotation of the secondary gear through the meshing of the gear slot and the secondary gear. The bottom of the counterweight 742 is fixedly connected with the constant force spring 748, which provides a constant elastic force and balances the gravity of the counterweight 742 with the friction between the counterweight 742 and the slide rod 741. The inner side of the protective shell 72 is fixedly connected with a support shaft 745, which provides support and rotation shaft for the secondary gear set 746; the other end of the support shaft 745 is provided with the secondary gear set 746, which includes two secondary gears connected through a connecting shaft, one of which is meshed with the gear slot plate 744, and the other of which is meshed with the main gear 747, converting the linear motion of the gear slot plate 744 into rotation, and realizing the synchronous rotation of the two secondary gears through the connecting shaft, amplifying and transmitting power. The inner side of the rotating ring 71 is fixedly connected with the main gear 747, which is meshed with the secondary gear set 746, receives the power transmitted by the secondary gear, and drives the rotating ring 71 to rotate.

[0044] The cleaning ring 75 comprises a plurality of scraping strips 751, one end of which is fixedly connected to the other end of the rotating ring 71, and the bottom of the scraping strip 751 is provided with a brush 752. The scraping strip 751 is scraped by its shape and hardness, and the stubborn impurities on the outer surface of the protective shell 72 and the glass window 732 are scraped. The brush 752 further sweeps the impurities; a plurality of elastic clamping rings 753 are arranged between the plurality of scraping strips 751, connecting the plurality of scraping strips 751, providing elastic support, so that the scraping strip 751 can adapt to the protective shell 72 of different shapes and surfaces, and at the same time provide a mounting and fixing structure for the light-transmitting lens 76. The inner side of the elastic clamping ring 753 is provided with the light-transmitting lens 76, which is in the shape of a circular cone with a wide upper part and a narrow lower part, and the angle between the outer axis and the central axis is 40 degrees, effectively guiding the light to converge to the lens, reducing the loss of light refraction; the upper and lower edges of the light-transmitting lens 76 are arranged in the shape of a rounded corner, preventing light scattering; and the outer surface of the light-transmitting lens 76 is provided with an anti-adhesion coating (i.e. a fluorosilane anti-adhesion coating, which is hydrophobic and oleophobic, so that impurities can easily slide off under the action of gravity or slight external force, keeping the mirror clean), thereby reducing impurities and ensuring the light transmission effect, ensuring that the camera 78 can normally shoot through the light-transmitting lens 76 during the rotation of the cleaning ring 75.

[0045] Working principle: when the camera mechanism of the ultraviolet curing repair device is used, first place the repair cylinder 1 at the position where ultraviolet curing repair is needed, and the fixing ring 4 at both ends of the repair cylinder 1 is stably supported by the telescopic column 5 and the support plate 6, ensuring that the device remains stable during work. The ultraviolet lamp 2 outside the repair cylinder 1 is started, and the ultraviolet curing repair work begins.

[0046] At this time, the camera 7 starts to work. The light passes through the glass window 732 on the light shield 731 into the light collection channel 733 outside the protective shell 72, which converges the light. The aperture gradually decreases from outside to inside, which enhances the light collection effect. After the light passes through the light collection channel 733, it is reflected by the mirror 734 inside the protective shell 72. The axis of the mirror 734 and the central axis of the protective shell 72 form an angle greater than 45 degrees and less than 90 degrees, so that the light can be accurately projected onto the light receiving plate 743. At this time, the liquid crystal elastomer material used by the light receiving plate 743 will swell to a certain extent under normal light irradiation. Since one side of the light receiving plate 743 is fixedly connected with one side of the counterweight 742, the swelling of the light receiving plate 743 will generate an outward pushing force on the counterweight 742. This pushing force interacts with the friction between the counterweight 742 and the slide rod 741, the elastic force of the constant force spring 748, and the gravity of the counterweight 742 itself, reaching a balanced state so that the counterweight 742 remains in the initial position unchanged. When the glass window 732 on the light shield 731 is disturbed by the accumulation of impurities, the light entering the glass window 732 decreases, thereby reducing the light intensity received by the light receiving plate 743. The light receiving plate 743 will shrink, reducing the pushing force on the counterweight 742, and further reducing the friction between the counterweight 742 and the slide rod 741. At this time, the gravity of the counterweight 742 is greater than the elastic force of the constant force spring 748 and the friction, so that the counterweight 742 moves downward. The sliding of the counterweight 742 drives the toothed plate 744 to move, and in turn drives one of the pinion gears in the secondary gear set 746 to rotate. Since the secondary gear set 746 is connected through the connecting shaft, the other pinion gear rotates synchronously to drive the main gear 747 to rotate, and finally drives the rotating ring 71 to rotate.

[0047] When the rotating ring 71 rotates, the cleaning ring 75 at the other end moves accordingly. The scraping strip 751 on the cleaning ring 75 and the bristles 752 at the bottom clean the impurities on the outer surface of the protective shell 72 and the impurities outside the glass window 732, ensuring the cleanliness of the surface of the protective shell 72 and avoiding the interference of impurities with the normal shooting of the lens. During the rotation of the cleaning ring 75, the camera 78 can perform shooting operations on the outside through the light-transmitting mirror 76, thereby avoiding the interference of the cleaning ring 75 with the normal shooting. At the same time, since the light-transmitting mirror 76 is in the shape of a conical taper with a wide upper end and a narrow lower end, the angle between the outer axis and the central axis is 40 degrees, which effectively guides the light to converge to the lens and avoids excessive angle causing light refraction loss. In addition, the upper and lower edges of the light-transmitting mirror 76 are rounded, thereby preventing light scattering at the edges, and the outer surface has an anti-adhesion coating, thereby reducing the attachment of impurities on the light-transmitting mirror 76 and ensuring the light transmission effect. Finally, the camera 78 captures the repair area, and the shooting signal is transmitted through the signal transmitter 79 at the end for real-time observation of the repair situation by the operator.

[0048] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
