Description

Technical Field

[0001] This utility model relates to the field of navigation lighting technology, and in particular to a port navigation lighting device. Background Technology

[0002] A waterway refers to navigable waters such as coastal areas and rafts. A waterway consists of navigable waters, navigational aids, and water conditions. During nighttime port maintenance and protection operations, LED lights are required for illumination. These lights are exposed to the elements for extended periods during operation, making them highly susceptible to dust accumulation. Even during the day, when the lights are not in use, they remain exposed, making them not only prone to dust contamination but also highly susceptible to damage from external forces.

[0003] For example, Chinese patent CN219300634U discloses a port and waterway navigation lighting device, in which the indicator lights are always exposed. Because existing lighting fixtures need to be exposed whether in working or idle states, external dust easily accumulates on the surface of the lighting fixtures, thus negatively affecting the brightness of the lighting fixtures during operation. Utility Model Content

[0004] This utility model provides a port navigation lighting device. The lighting lamp is stored in a protective box when idle by a lifting mechanism and sealed with a partition, thereby preventing the lighting lamp from getting dusty when idle and helping to ensure the lighting effect.

[0005] This utility model provides a port navigation lighting device, including a protective box, a lighting lamp, and a lifting mechanism. The lighting lamp is disposed on the top of the lifting mechanism, which is located inside the protective box. The protective box includes a box body and a partition. The side of the box body has a slot for inserting the partition, and the top of the box body has an opening for the lighting lamp to extend out of the box body. The partition inserted into the slot can close the opening.

[0006] In one embodiment, the top of the housing is further provided with a cleaning mechanism, which includes a mounting base, a limiting plate, a guide rod, a cleaning plate, and a spring. The mounting base is annular, and a plurality of the limiting plates are spaced apart on the surface of the mounting base. One end of the guide rod passes through the limiting plate and is slidably connected to the limiting plate. The cleaning plate is disposed at the other end of the guide rod, and the spring is sleeved on the guide rod and located between the cleaning plate and the limiting plate.

[0007] In one embodiment, the inner diameter of the mounting base is larger than the diameter of the opening.

[0008] In one embodiment, the surface of the cleaning plate is provided with a flexible pad.

[0009] In one embodiment, the cleaning plate is arc-shaped, and the sides of the plurality of cleaning plates away from the limiting plate are located on the same circumference.

[0010] In one embodiment, a plurality of the limiting plates are disposed at equal intervals on the surface of the mounting base.

[0011] In one embodiment, the top of the housing is further provided with a drive mechanism. The mounting base is a gear structure and is rotatably disposed on the top of the housing. The drive mechanism includes a drive gear, a motor, and a bracket. The bracket is fixed to the top of the housing. The motor is connected to the bracket. The drive gear is disposed at the output end of the motor and meshes with the mounting base.

[0012] In one embodiment, the number of teeth of the drive gear is less than the number of teeth of the mounting base.

[0013] In one embodiment, the bracket is U-shaped and includes a crossbar and two uprights. One end of each upright is connected to the end of the crossbar, and the other end of each upright is fixed to the surface of the housing.

[0014] In one embodiment, the slots are located on two opposite sides of the housing.

[0015] Compared with existing technologies, the advantages of this invention are that the lifting mechanism allows the lighting lamp to move up and down, so that the lamp extends out of the opening at the top of the housing during operation and retracts into the housing when not in use. By inserting a partition into the slot on the housing to seal the opening, dust accumulation on the lamp surface can be reduced, ensuring the lamp's performance. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown, a port navigation lighting device according to an embodiment of the present invention includes a protective box 1, a lighting lamp 2, and a lifting mechanism 3. The lighting lamp 2 is disposed on the top of the lifting mechanism 3, and the lifting mechanism 3 is located inside the protective box 1. The protective box 1 includes a box body 11 and a partition 12. The side of the box body 11 is provided with a slot 100 for inserting the partition 12, and the top of the box body 11 is provided with an opening 200 for the lighting lamp 2 to extend out of the box body 11. The partition 12 inserted into the slot 100 can close the opening 200.

[0025] The lifting mechanism 3 allows the lighting lamp 2 to move up and down, so that the lighting lamp 2 extends out of the opening 200 at the top of the housing 11 when in operation, and retracts into the housing 11 when not in use. By inserting the partition 12 into the slot 100 on the housing 11 to seal the opening 200, the adhesion of dust on the surface of the lighting lamp 2 can be reduced, ensuring the effectiveness of the lighting lamp 2.

[0026] like Figure 3 As shown, slots 100 are provided on two opposite sides of the housing 11. When it is necessary to close the opening 200 using the partition 12, a slot 100 extends from each end of the partition 12, so that the partition 12 can be stably placed in the housing 11.

[0027] like Figure 2 and Figure 4 As shown, the top of the housing 11 is also provided with a cleaning mechanism 4. The cleaning mechanism 4 includes a mounting base 41, a limiting plate 42, a guide rod 43, a cleaning plate 44, and a spring 45. The mounting base 41 is ring-shaped, and multiple limiting plates 42 are spaced apart on the surface of the mounting base 41. One end of the guide rod 43 passes through the limiting plate 42 and is slidably connected to the limiting plate 42. The cleaning plate 44 is disposed at the other end of the guide rod 43, and the spring 45 is sleeved on the guide rod 43 and located between the cleaning plate 44 and the limiting plate 42.

[0028] Since the shape of the lighting lamp 2 is similar to that of a sphere, the lighting lamp 2 will exert a certain amount of pressure on the cleaning plate 44 during the lifting and lowering process. When the cleaning plate 44 is pressured, the cleaning plate 44 and the guide rod 43 will move. The spring 45 provides a certain elastic force to keep the cleaning plate 44 in contact with the surface of the lighting lamp 2, thereby cleaning the surface of the lighting lamp 2 better.

[0029] To avoid obstructing the raising and lowering of the lighting lamp 2, the inner diameter of the mounting base 41 is larger than the diameter of the opening 200. When installing the mounting base 41 onto the top of the housing 11, ensure that the inner hole of the mounting base 41 is concentric with the opening 200.

[0030] In order to better fit the surface of the lighting lamp 2 and reduce wear on the surface of the lighting lamp 2, the surface of the cleaning plate 44 is provided with a flexible pad (not shown in the figure). In this embodiment, the flexible pad is a cotton pad, and the cleaning plate 44 is a wooden board.

[0031] like Figure 2 and Figure 4 As shown, the cleaning plate 44 is arc-shaped, and the sides of multiple cleaning plates 44 furthest from the limiting plate 42 are located on the same circumference. This ensures that all cleaning plates 44 can achieve good adhesion to the surface of the lighting lamp 2.

[0032] Furthermore, multiple limiting plates 42 are equally spaced on the surface of the mounting base 41, so that each cleaning plate 44 can be evenly distributed along the circumference, so that the pressure from each cleaning plate 44 on the lighting lamp 2 cancels each other out, and no lateral shear force is applied to the lighting lamp 2, thus ensuring the stability of the lighting lamp 2 during the lifting process.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the top of the housing 11 is also provided with a drive mechanism 5. The mounting base 41 is a gear structure and is rotatably mounted on the top of the housing 11. The drive mechanism 5 includes a drive gear 51, a motor 52 and a bracket 53. The bracket 53 is fixed to the top of the housing 11. The motor 52 is connected to the bracket 53. The drive gear 51 is located at the output end of the motor 52 and meshes with the mounting base 41.

[0034] When the middle part of the lighting lamp 2, i.e., the part with the largest diameter, comes into contact with the cleaning plate 44, the spacing between the cleaning plates 44 is relatively large, resulting in a large area of ​​the surface of the lighting lamp 2 that cannot be cleaned by the cleaning plates 44. However, after the drive mechanism 5 is set up, the drive gear 51 can drive the mounting base 41 to rotate, thereby greatly increasing the area that the cleaning plates 44 can clean and achieving a better cleaning effect.

[0035] Furthermore, the number of teeth on the drive gear 51 is less than the number of teeth on the mounting base 41, which amplifies the torque of the motor 52. Even if the cleaning plate 44 is in close contact with the surface of the lighting lamp 2, the mounting base 41 will not be unable to rotate due to the large friction between the cleaning plate 44 and the surface of the lighting lamp 2.

[0036] like Figure 2 and Figure 4 As shown, the bracket 53 is U-shaped and includes a crossbar 531 and two uprights 532. One end of each upright is connected to the end of the crossbar 531, and the other end is fixed to the surface of the housing 11. The bracket 53 has a simple structure, occupies little space, is easy to place on top of the housing 11, and has high reliability. The space between the two uprights 532 is large enough to accommodate both the motor 52 and the drive gear 51.

[0037] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
