[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, a navigation lighting device for port and waterway engineering includes: a lamp body 1 for lighting; a fan 2 arranged on the top of the lamp body 1; a positioning plate 3 arranged below the fan 2, and the fan 2 is rotatably connected to the positioning plate 3; a limiting component 4 arranged at the bottom of the fan 2; a base 5 rotatably connected to the positioning plate 3; a floating block 6 arranged in the middle of the base 5; a floating component 7 connected to the dock; and an anti-drifting component 8 arranged on the side wall of the base 5.

[0024] The device is installed on the front side wall of the dock. It emits light to mark the edge of the dock for incoming ships, making it easier for ships to navigate to the shore.

[0025] Lamp body 1 features an LED headlight with a shade. Its high brightness makes it easy for navigational personnel to spot. A fan 2 is mounted above the lamp body 1. A threaded post 11 is located at the top of the lamp body 1. A through-hole is located at the rear end of the fan 2, through which the threaded post 11 extends. A nut is screwed onto the threaded post 11. The nut secures the fan 2 to the lamp body 1. The air outlet of the fan 2 faces the surface of the lamp body 1. The fan 2 is activated intermittently at a set time. This blows away condensation and mist from the lampshade, maintaining a clear, transparent light. A heating element is incorporated into the fan 2. During winter, the fan 2 generates heated air, effectively preventing ice from forming on the surface of the lamp body 1. During daytime, the intermittent hot air flow keeps the surface of the lamp body 1 free of residual ice. At night, the light can be instantly brightened to the desired brightness, allowing the lamp 1 to function normally even in cooler temperatures. The hot air also keeps the internal components of the lamp body 1 dry, extending their lifespan.

[0026] A pivot 31 is provided on the sidewall of the positioning plate 3. An extension plate 12 is provided on the sidewall of the lamp body 1. The pivot 31 extends through the extension plate 12 and the sidewall of the positioning plate 3. The pivot 31 allows the illumination direction of the lamp body 1 to be changed. When the lamp body 1 is tilted upward, the dock position can be seen by ships further away. Once the tilt angle of the lamp body 1 is determined, the limit assembly 4 is used to fix the tilt angle of the lamp body 1. This angle does not change during navigation.

[0027] The position-limiting assembly 4 includes: positioning grooves 41 provided on the positioning plate 3, with the positioning grooves 41 being evenly spaced on both sides of the positioning plate 3; positioning rods 42 rotatably connected to the bottom of the lamp body 1, with the center rod 13 at the bottom of the lamp body 1. Two positioning rods 42 are provided, one facing the front of the lamp body 1 and the other facing the rear of the lamp body 1; and a clamping block 43 rotatably connected to the end of the positioning rod 42. The clamping block 43 can be inserted into the positioning groove 41. When the tilt angle of the lamp body 1 is determined, the clamping block 43 is rotated and engaged into the positioning groove 41, limiting the rotation of the positioning rod 42 and thus preventing the lamp body 1 from rotating.

[0028] like Figure 2 As shown, a rotating motor 51 is provided on the top of the base 5, and the output end of the rotating motor 51 is fixedly connected to the bottom of the positioning plate 3. The rotating motor 51 is controlled by remote control to further change the direction of the light to provide lighting navigation for ships in different directions. A protective cover 32 is provided at the bottom of the positioning plate 3. The protective cover 32 surrounds the rotating motor 51 and rotates with the positioning plate 3. The protective cover 32 reduces the entry of water vapor into the rotating motor 51.

[0029] A protective plate 52 is provided on the side wall of the base 5. The protective plate 52 is L-shaped. There are two protective plates 52 facing each other. The vertical surface of the protective plate 52 is the top surface, the horizontal surface of the protective plate 52 is the bottom surface, and the bottom of the protective plate 52 extends toward the inside of the base 5.

[0030] A floating block 6 is mounted at the bottom of the protective plate 52 and is screwed to the protective plate 52. The screws secure the floating block 6 to the protective plate 52. The bottom of the floating block 6 is in contact with the water surface, preventing the device from sinking and allowing it to move up or down with the water level. This prevents the lamp body 1 from being submerged in the seawater, ensuring that the lamp body 1 can illuminate at any time.

[0031] The floating assembly 7 includes a positioning rail 71 and a sliding rod 72. The positioning rail 71 is fixed to the side wall of the dock. One end of the sliding rod 72 is fixed to the protective plate 52, and the other end of the sliding rod 72 is slidably connected to the positioning rail 71. The positioning rail 71 restricts the movement of the lamp body 1 to only up and down, which helps to prevent the lamp body 1 from being blown away by the sea water and keeps the direction of the light fixed, which facilitates navigation.

[0032] like Figure 3As shown, the anti-drift assembly 8 is used to position the device during inclement weather. The anti-drift assembly 8 includes a winding shaft 81 and an anchor hook 82. The winding shaft 81 is provided with a pull line 811, which is connected to the anchor hook 82. The winding shaft 81 is rotatably connected to the side wall of the protective plate 52. When the device is installed, the anchor hook 82 is placed underwater. If the positioning rod 42 or the sliding rod 72 breaks during inclement weather at the port, the anchor hook 82 is anchored to the seabed, reducing the floating range of the device and facilitating its subsequent recovery. When the anchor hook 82 is recovered, the winding shaft 81 is rotated to rewind the pull line 811 around it.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
