[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5This utility model provides a technical solution: an anti-glare, flip-up surveillance lens light shield assembly, including a fixed panel 7, a rotating ring 3 rotatably connected to the fixed panel 7, the rotating ring 3 being rotatably connected to the fixed panel 7 via bearings, a connecting rod 9 fixedly connected to the other end of the rotating ring 3, a connecting plate 8 fixedly connected to one end of the connecting rod 9, a shaft provided at one end of the connecting plate 8, the shaft of the connecting plate 8 being connected to the shaft of a flip motor 12 via bearings. This structure drives the rotating ring 3 to rotate automatically through the flip motor 12, the connecting plate 8, and the connecting rod 9. The rotation of the rotating ring 3 allows for adjustment of the angles of the main light shield 4 and the side light shield 6. A fixed base 13 is fixedly connected to one end of the fixed panel 7, and a flip motor 12 is installed inside the fixed base 13. 2 is connected to the rotating ring 3 for transmission. The other end of the fixed panel 7 is fixedly connected to the monitoring body 2. One end of the monitoring body 2 is fixedly connected to the monitoring bracket 1. The monitoring bracket 1 is fixed to the fixed panel 7 by bolts. This structure can ensure the stability of the installation of the monitoring body 2 and the fixed panel 7. The length of the main light shield 4 and the side light shield 6 is greater than the length of the monitoring body 2, so that the main light shield 4 and the side light shield 6 can protect the lens of the monitoring body 2. One end of the rotating ring 3 is fixedly connected to the main light shield 4. The main light shield 4 has an arc-shaped structure and a hollow structure inside. Side light shields 6 are inserted at both ends of the main light shield 4. The side light shields 6 are symmetrically distributed about the bisector of the main light shield 4. The outer wall of the side light shield 6 is also provided with a slider 11. The inner wall of the main light shield 4 A sliding groove is provided, and a slider 11 is inserted into the groove. The slider 11 is symmetrically distributed about the bisector of the gear ring 10. The side light shield 6 and the main light shield 4 are slidably connected. The inner wall of the main light shield 4 has a groove, and a gear 14 is rotatably connected inside the groove. The gear 14 is symmetrically distributed about the bisector of the main light shield 4. The main light shield 4 and the side light shield 6 are made of anti-glare material, such as black light-absorbing material. The inner wall of the main light shield 4 and the side light shield 6 can be set with a honeycomb structure to continuously absorb stray light inside, preventing it from reflecting back to the lens of the monitoring body 2. The main light shield 4 and the side light shield 6, through their outward-extending structure, physically block these stray lights that are not in the imaging direction, like a "sun hat," reducing their entry into the lens of the monitoring body 2. In this structure, a first bevel gear 15 is fixedly connected to the shaft of gear 14, and a second bevel gear 16 is also provided on the inner wall of the groove of the main light shield 4 via a shaft. This structure allows the gear ring 10 and the side light shield 6 to move by rotating gear 14, enabling the side light shield 6 to extend and retract within the main light shield 4. This facilitates adjustment of the protection range of the main light shield 4 and the side light shield 6. The second bevel gear 16 is located at one end of the first bevel gear 15 and meshes with it. One end of the shaft of the second bevel gear 16 is connected to the shaft of the adjusting motor 5. The adjusting motor 5 can drive the second bevel gear 16 to rotate automatically. During rotation, the second bevel gear 16 drives the first bevel gear 15 and gear 14 to rotate. The adjusting motor 5 is controlled by a PLC.The outer wall of the adjusting motor 5 can be protected by a protective shell. This is existing technology and will not be described in detail here. A gear ring 10 is provided on the outer wall of the side sunshade 6. A gear 14 is rotatably connected to the inner wall of the main sunshade 4, and the gear 14 meshes with the gear ring 10. The adjusting motor 5 is fixedly connected to the outer wall of the main sunshade 4, and the adjusting motor 5 is driven by the gear 14.

[0019] Working principle: When using this anti-glare flip-up surveillance lens hood assembly, first fix the fixing base 13 to the wall with bolts. Then, adjust the light-blocking effect of the surveillance body 2 lens according to the requirements. During adjustment, first adjust the light-blocking range of the surveillance body 2. At this time, start the adjustment motor 5. The adjustment motor 5 drives the second bevel gear 16 and the first bevel gear 15 to rotate. During the rotation of the first bevel gear 15, it pushes the gear 14 and the gear ring 10, thereby driving the side light-blocking cover 6 to move inside the main light-blocking cover 4. The effect of different light-blocking ranges is adjusted by the extension and retraction of the side light-blocking cover 6. After the side light-blocking cover 6 is adjusted, the light-blocking angle of the main light-blocking cover 4 and the side light-blocking cover 6 is adjusted. During adjustment, the flip motor 12 drives the connecting plate 8 and the rotating ring 3 to rotate. When the rotating ring 3 rotates, it drives the side light-blocking cover 6 to adjust to a suitable angle in the main light-blocking cover 4. When the side light-blocking cover 6 is adjusted to the right angle in the main light-blocking cover 4, it can be used for formal use.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
