[0002] Floodlights are lamps with a higher illumination on the designated illuminated surface than the surrounding environment, also known as spotlights. Usually, they can be aimed in any direction and have a structure that is not affected by climatic conditions. They are mainly used in large-area work sites, mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting lamps used outdoors can be regarded as floodlights;

[0003] After searching, the applicant found that a Chinese patent disclosed "a waterproof heat dissipation device for LED floodlights", and its publication (announcement) number is "CN 210107168 U". This patent mainly uses a waterproof heat dissipation device with a reasonable design. It can effectively prevent water from entering the floodlight through the water inlet when working on rainy days, causing damage to the lamp. It is suitable for promotion and use. However, after the angle adjustment is completed, the device cannot support and fix the position of the floodlight. Therefore, when used at a set angle, the stability of the floodlight is poor. For this reason, we propose a waterproof heat dissipation device for LED floodlights. Utility Model Content

[0024] Example 2, please refer to the attached Figure 1 -Attached Figure 4 The utility model provides a technical solution: a waterproof heat dissipation device for an LED floodlight, comprising a heat dissipation device body 1, the heat dissipation device body 1 comprising a clamping mechanism 2 and a water shielding mechanism 3, the water shielding mechanism 3 being located above the clamping mechanism 2, the clamping mechanism 2 comprising a mounting base 11, a movable lifting plate 15, a smooth clamping block 22 and a clamping block 24, an adjusting groove 14 is provided on the top wall of the mounting base 11, the inner wall of the adjusting groove 14 is slidably connected to the outer wall of the movable lifting plate 15, smooth grooves 21 are provided on the left and right sides of the movable lifting plate 15, the inner wall of the smooth groove 21 is slidably connected to the smooth clamping block 22, the rear wall of the smooth clamping block 22 is fixedly connected to the front wall of the epitaxial column 23, and the epitaxial column 23 extends to the outside of the movable lifting plate 15, the upper end of the mounting base 11 is located on the left and right sides of the adjusting groove 14 and is fixedly connected with the clamping block 24, and the clamping block 24 and the smooth clamping block 22 cooperate with each other.

[0025] Please see attached Figure 1 and attached Figure 2 The water shielding mechanism 3 includes a water retaining frame 31, a waterproof plate 32, a rotating rod 33, an iron block 34 and a magnetic block 35. The two water retaining frames 31 are rotatably connected to the left and right ends of the rotating rod 33, the outer wall of the rotating rod 33 is fixedly connected to the waterproof plate 32, the lower end of the waterproof plate 32 is connected to the upper end of the iron block 34 away from the rotating rod 33, the iron block 34 and the waterproof plate 32 are fixedly connected, the upper end of the projection box 13 is fixedly connected to the lower end of the magnetic block 35 away from the lower side of the water retaining frame 31, and the magnetic block 35 and the iron block 34 cooperate with each other.

[0026] In this embodiment, the waterproof plate 32 can achieve a waterproof effect, thereby shielding the light projection surface of the light projection box 13, so that the light projection surface can be shielded when it rains and the light projection box is not in use.
