Description

Technical Field

[0001] The utility model belongs to the field of port facilities, and particularly relates to a port waterway lighting device. Background Art

[0002] An approach channel is a connecting channel between the deep sea or water transportation trunk line and the port water area, and its function is to enable ships to safely enter and leave the port. In order to enable ships to pass safely and conveniently, guide dikes are generally arranged on one or both sides thereof, so that the incoming ships have good shelter conditions. Port waterways are important water transportation channels, which connect the ocean and the inland and provide ships with access to various ports.

[0003] The lighting device of the port waterway is an important facility to ensure the safety of the waterway and improve the navigation efficiency. Its main function is to provide necessary lighting to ensure the safety of navigation. The lighting device is installed at key parts of the waterway, such as turning points, intersections and other areas with large ship traffic. Since the lighting device of the port waterway floats on the water surface and has high humidity, the existing lighting device has poor sealing performance, and water vapor invades the lighting device. On the one hand, it causes the lighting lamp to short-circuit and the device to be damaged, affecting the use, and even causing ship collision accidents. On the other hand, after the water vapor invades, the lamp cover becomes blurred and cannot provide sufficient brightness for the ships, affecting the entry or exit of ships into or out of the port. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the utility model provides a port waterway lighting device with strict sealing to prevent water vapor from entering the lamp body and extend the service life of the lighting device.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A port waterway lighting device includes a lamp base fixedly connected to a floating board and a lamp cover detachably connected to the lamp base. A lamp body for lighting is fixed on the lamp base. Multiple circles of absorbent cotton strips are fixed on the lamp base around the lamp body. Multiple circles of sealing strips are arranged below the lamp cover. A receiving cavity is formed in the lamp cover between the sealing strips. The top ends of the absorbent cotton strips extend into the receiving cavity.

[0007] Further, the lamp cover includes a main body cover for covering the lamp body and an annular connecting plate arranged below the main body cover. The inner ring edge of the connecting plate is connected to the bottom edge of the main body cover. The connecting plate has a certain thickness. Multiple through holes are formed in the connecting plate, and the through holes are arranged outside the sealing strips. The main body cover can be, for example, a hollow cylinder.

[0008] Furthermore, the sealing strip is fixed to the bottom surface of the connecting plate. The sealing strip protrudes away from the connecting plate. The sealing strip has at least two turns, preferably three turns. The material of the sealing strip can be, for example, rubber. The width of the sealing strip can be, for example, 3 - 6 mm, preferably about 3.5 mm. The height of the sealing strip can be, for example, 1 - 5 mm, preferably about 2 mm.

[0009] Furthermore, a receiving cavity is formed in the connecting plate between the sealing strips. The receiving cavity surrounds the main body cover. The cross-sectional shape of the receiving cavity is the same as that of the water-absorbing cotton strip. The depth of the receiving cavity is preferably greater than the height of the water-absorbing cotton strip. When the lamp cover is connected to the lamp base, the top end of the water-absorbing cotton strip can extend into the receiving cavity.

[0010] Furthermore, the water-absorbing cotton strip is arranged around the lamp body and corresponds to the receiving cavity. The water-absorbing cotton strip can be, for example, two turns. The height of the water-absorbing cotton strip is greater than the height of the sealing strip. The material of the water-absorbing cotton strip can be, for example, synthetic fiber blend. The water-absorbing cotton strip is used to absorb the infiltrated water.

[0011] Furthermore, a plurality of limiting holes are formed in the lamp base around the water-absorbing cotton strip. The number of limiting holes is at least two, preferably four. The plurality of limiting holes are evenly distributed around the lamp body.

[0012] Furthermore, a plurality of threaded holes are provided on the lamp base. The plurality of threaded holes are arranged outside the water-absorbing cotton strip and distributed along the circumferential direction of the water-absorbing cotton strip. The number of threaded holes is at least two, preferably four. The threaded holes and the limiting holes are arranged at intervals. The positions of the threaded holes correspond to the positions of the through holes on the connecting plate.

[0013] Furthermore, a plurality of limiting posts are fixed to the bottom surface of the connecting plate. The number of limiting posts is the same as the number of limiting holes. The positions of the limiting posts correspond to the positions of the limiting holes on the lamp base. When the limiting posts are inserted into the limiting holes, the through holes and the threaded holes are coaxial. The bolt passes through the through hole and is screwed into the threaded hole to realize the connection between the lamp cover and the lamp base.

[0014] The working process of a port waterway lighting device of the present utility model:

[0015] First, align the limiting posts of the lamp cover with the limiting holes of the lamp base, and place the lamp cover downward so that the limiting posts are inserted into the limiting holes. At this time, the through holes and the threaded holes are coaxial. The bolt passes through the through hole and is screwed into the threaded hole. During the process of screwing in the bolt, the lamp cover gradually approaches the lamp base, and the multi-turn sealing strip is squeezed and expanded. At the same time, the top end of the water-absorbing cotton strip gradually extends into the receiving cavity until the bolt is tightened. The squeezed sealing strip forms a seal between the connecting plate and the lamp base, playing a role in preventing water vapor from entering. If water seeps in through the sealing strip, the water-absorbing cotton strip is used to absorb water and blocks the water from entering the lamp cover again. When the lamp body needs to be replaced, repaired, or maintained, loosen the bolt, remove the lamp cover, and expose the lamp body for operation.

[0016] The beneficial effects of the present utility model:

[0017] A port waterway lighting device of the present utility model forms multi-layer sealing protection for the lamp body through multiple circles of sealing strips arranged below the lamp cover. The sealing strips effectively prevent moisture from entering the interior of the lamp cover, protect the lamp body from water invasion, and extend the service life. The moisture around the lamp body is absorbed by multiple circles of absorbent cotton strips fixed on the lamp base, reducing the influence of moisture on the lamp body and further protecting the internal circuits and components of the lighting device. The sealing strips and absorbent cotton strips are arranged crosswise and used in combination to prevent moisture from seeping in at the connection between the lamp cover and the lamp base, improving the moisture-proof effect of the entire lighting device. The detachable connection between the lamp cover and the lamp base facilitates the replacement, repair, or maintenance of the lamp body. The port waterway lighting device of the present utility model is applicable to various water environments, has good environmental adaptability, is waterproof, moisture-proof, easy to maintain, and has strong adaptability while ensuring the lighting effect.
