Description

Technical Field

[0001] This invention relates to the field of marine engineering, specifically to a lamp holder, a foremast light assembly, and a roll-on / roll-off ship. Background Technology

[0002] On existing roll-on / roll-off (Ro-Ro) ships, passenger Ro-Ro ships, and large car carriers, the foremast light is typically fixed directly to the top of a light post above the forecastle deck or main deck. However, to accommodate bow doors, windbreaks, and longitudinal escape staircases leading to the life deck, these vessels often have large, vertical, or slightly inclined steel plate structures installed directly aft and to the sides of the light post. Traditional light holders consist of only a horizontal base plate and several stiffening plates welded together, with their orientation parallel to the ship's centerline, resulting in strong specular reflection from the foremast light. During nighttime navigation, the reflected light shines directly onto the lookout area directly above and in front of the bridge, creating a high-brightness glare band on the windshield, hindering visibility and posing a significant safety hazard. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect of the reflected light of the foremast light affecting the lookout in the prior art, and to provide a lamp holder, a foremast light assembly and a roll-on / roll-off ship.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A lamp holder for mounting a foremast light on a roll-on / roll-off ship, the lamp holder comprising:

[0006] The back plate includes a first back plate and a second back plate, the first back plate and the second back plate are connected and form an obtuse angle;

[0007] A shelf, the shelf being connected to the front side of the back panel;

[0008] A plurality of light-shielding plates, wherein the plurality of light-shielding plates protrude upward relative to the layer plate, and the light-shielding plates are provided at least at both ends of the layer plate along the length direction of the lamp holder.

[0009] In this technical solution, by installing a backplate on the lamp holder and configuring the backplate into a first and a second backplate with obtuse angles, the main optical axis of the foremast light can be "folded" towards the bow, increasing the angle of incidence of the light with the forecastle windbreak and the escape staircase facade, and reducing specular reflection. Simultaneously, by installing shelves and light shields, light that may obstruct the navigator's view can be blocked, preventing impaired lookout and improving navigational safety.

[0010] Preferably, the light-shielding plate is rotatably connected to the shelf, and the light-shielding plate can rotate relative to the shelf about the width direction of the shelf to change the height of the light-shielding plate protruding upward relative to the shelf.

[0011] In this technical solution, by setting the light shield to be adjustable, the same light holder can cover a variety of roll-on / roll-off ships with different forecastle windbreak angles, eliminating the need to redesign the light holder, achieving "one light for multiple uses" and expanding the applicability of the light holder.

[0012] Preferably, the length of the shelf is greater than the length of the back plate, and both ends of the shelf protrude relative to the back plate along the length direction.

[0013] In this technical solution, by setting the length of the shelf to be greater than that of the back plate, a cantilever structure is formed, which allows rainwater and deck wash water to be discharged externally, thus improving the lifespan of the lamp holders. At the same time, the cantilevered part becomes the pivot point of the light shield, improving the structural integration.

[0014] Preferably, the light-shielding plate is also disposed at the rear end of the layer plate, and is located at least in the portion of the layer plate that protrudes along the length direction relative to the back plate.

[0015] In this technical solution, by also installing a light shield on the rear side of the lamp holder, the light rays shining backward can be blocked, reducing the amount of light illuminating the sea surface.

[0016] Preferably, the shelf includes an upper shelf and a lower shelf spaced apart along the vertical direction. The upper shelf has a perforated structure at the middle position along the length direction, and the perforated structure extends to the front end of the upper shelf. The width of the perforated structure along the length direction is not less than the diameter of the masthead light.

[0017] In this technical solution, by setting an upper plate and a lower plate, two sets of light-shielding structures are formed, which can be applied to mast lights with upper and lower double-layer lamp bodies.

[0018] Preferably, the light-shielding plate connected to the upper plate protrudes downward relative to the upper plate.

[0019] In this technical solution, by setting the upper light shield to bulge downwards, the stray light in the dark area between the upper and lower light bodies of the double-layer masthead light can be cut off, avoiding bright spots appearing in the gap between the two light bodies, so that the light arcs of the two light bodies still appear as continuous white arcs at a distance.

[0020] Preferably, the lamp holder further includes a bracket connected to the back of the back plate;

[0021] The bracket includes a first support portion and a second support portion. One end of the first support portion is connected to the back plate, and the other end of the first support portion extends along the front-rear direction of the lamp holder. One end of the second support portion is connected to the first support portion and has a first distance between it and the back plate. The other end of the second support portion is connected to the back plate and is located above the first support portion.

[0022] In this technical solution, by setting up a bracket to form a triangular structure, the stability of the lamp holder and the wind resistance performance can be improved.

[0023] Preferably, there are two brackets, and the two brackets are respectively connected to the first back plate and the second back plate;

[0024] One end of the first support is connected to the bottom of the back plate.

[0025] In this technical solution, paired triangular brackets simultaneously fix the first back plate and the second back plate, avoiding torsional errors caused by unilateral welding.

[0026] Preferably, the included angle between the first back plate and the second back plate is not less than 140°;

[0027] And / or, the included angle between the first back plate and the second back plate is not greater than 150°.

[0028] Preferably, the lamp holder further includes a plurality of first reinforcing ribs, which are disposed on the layer plate.

[0029] In this technical solution, by setting a first reinforcing rib on the shelf, the local rigidity of the shelf can be enhanced, and the wind resistance of the lamp holder can be improved.

[0030] Preferably, the lamp holder further includes a second reinforcing rib, which is disposed on the back plate.

[0031] In this technical solution, by setting a first reinforcing rib on the layer plate, the local rigidity of the back plate can be enhanced, and the wind resistance of the lamp holder can be improved.

[0032] A masthead light assembly, the masthead light assembly comprising a masthead light, a light pole, and a light holder as described above.

[0033] Preferably, the masthead light includes a first lamp body and a second lamp body spaced apart in a vertical direction;

[0034] The shelf includes an upper shelf and a lower shelf spaced apart along the vertical direction. The upper shelf has a hollow structure at the middle position along the length direction. The hollow structure extends to the front end of the upper shelf. The width of the hollow structure along the length direction is not less than the diameter of the masthead light.

[0035] The projection of the light-shielding plate located on the upper plate in the vertical direction at least covers the gap between the first lamp body and the second lamp body;

[0036] In this technical solution, by setting the light shield so that its projection in the vertical direction at least covers the gap between the first lamp body and the second lamp body, the light shield can cut off stray light between the first lamp body and the second lamp body, ensuring the continuity of the light arc.

[0037] Preferably, the lamp holder further includes a bracket connected to the back of the back plate;

[0038] The bracket includes a first support part and a second support part. One end of the first support part is connected to the back plate, and the other end of the first support part extends along the front-back direction of the lamp holder. One end of the second support part is connected to the first support part and has a first distance between it and the back plate. The other end of the second support part is connected to the back plate and is located above the first support part.

[0039] The first support is connected to the lamp post.

[0040] In this technical solution, by connecting the bracket to the lamp post, the lamp holder and the lamp post can be integrated.

[0041] The positive and progressive effects of this invention are as follows: By installing a backplate on the lamp holder, and configuring the backplate into a first backplate and a second backplate with obtuse angles, the main optical axis of the foremast light can be "folded" towards the bow, increasing the angle of incidence of the light with the forecastle windbreak and the facade of the escape staircase, and reducing specular reflection. Simultaneously, by installing shelves and light shields, light that affects the navigator's vision can be blocked, preventing obstruction of lookout and improving navigational safety.

[0060] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0061] This embodiment provides a roll-on / roll-off (Ro-Ro) vessel equipped with a foremast light assembly, which includes a foremast light, a light mast, and a light base 100. Figures 1-4 As shown, the lamp holder 100 includes a back plate 1, a shelf 2, and multiple light-shielding plates 3. The back plate 1 includes a first back plate 11 and a second back plate 12, which are connected and form an obtuse angle. The shelf 2 is connected to the front of the back plate 1. The light-shielding plates 3 protrude upward relative to the shelf 2 and are at least located at both ends of the shelf 2 along the length of the lamp holder 100. By setting the back plate 1 on the lamp holder 100 and configuring the back plate 1 as the first back plate 11 and the second back plate 12 forming an obtuse angle, the main optical axis of the foremast light can be "folded" towards the bow, increasing the angle of incidence of the light with the forecastle windbreak and the escape staircase facade, and reducing specular reflection. At the same time, by setting the shelf 2 and the light-shielding plates 3, light that affects the driver's vision can be cut off, avoiding obstruction of lookout and improving navigation safety.

[0062] Specifically, in this embodiment, the light-shielding plate 3 is fixed on the layer plate 2.

[0063] Of course, in other embodiments, the light-shielding plate 3 can be rotatably connected to the shelf 2, and the light-shielding plate 3 can rotate relative to the shelf 2 about the width direction of the shelf 2 to change the height of the upward protrusion of the light-shielding plate 3 relative to the shelf 2. By making the light-shielding plate 3 adjustable, the same lamp holder 100 can cover a variety of roll-on / roll-off ships with different forecastle windbreak wall inclination angles, eliminating the need to redesign the lamp holder 100, achieving "one unit for multiple uses", and expanding the applicability of the lamp holder 100.

[0064] In this embodiment, the length of the shelf 2 is greater than the length of the back plate 1, and both ends of the shelf 2 protrude from the back plate 1 along the length direction. By setting the length of the shelf 2 to be greater than the length of the back plate 1, a cantilever structure is formed, and rainwater and deck washing water are discharged externally, which can improve the life of the lamp holder 100. At the same time, the cantilevered part becomes the pivot point of the light shield 3, and the structural integration is improved.

[0065] Of course, in other embodiments, the shelf 2 may also be configured to be the same length as the back plate 1, which will not be elaborated here.

[0066] Specifically, the height of the sunshade 3 and the width of the shelf 2 can be set according to the size of the masthead light, or can be adjusted adaptively through the adjustment function of the sunshade 3, which will not be elaborated here.

[0067] In this embodiment, the light-shielding plate 3 is also disposed at the rear end of the layer plate 2, and is located at least in the portion of the layer plate 2 that protrudes along the length direction relative to the back plate 1. By also disposing of the light-shielding plate 3 on the rear side of the lamp holder 100, light rays directed to the rear can be blocked, reducing the amount of light illuminating the sea surface.

[0068] Specifically, in this embodiment, the masthead light is a double-layered light, which includes a first light body and a second light body spaced apart in the vertical direction. The layer plate 2 includes an upper layer plate 21 and a lower layer plate 22 spaced apart in the vertical direction. The upper layer plate 21 has a hollow structure at the middle position along the length direction, which extends to the front end of the upper layer plate 21. The width of the hollow structure along the length direction is not less than the diameter of the masthead light. The hollow structure is used for mounting the masthead light. By setting the upper layer plate 21 and the lower layer plate 22, two sets of light-shielding structures are formed, which can be applied to the masthead light with upper and lower double-layered light bodies.

[0069] Specifically, the light-shielding plate 3 connected to the upper plate 21 protrudes downward relative to the upper plate 21. The projection of the light-shielding plate 3 in the vertical direction on the upper plate 21 at least covers the gap between the first and second lamp bodies. Specifically, in this embodiment, the width of the perforated structure along its length is equal to the diameter of the masthead light, the light-shielding plate 3 is arranged vertically, and the vertical dimension of the upper light-shielding plate 3 is equal to the gap between the first and second lamp bodies.

[0070] Of course, in other embodiments, the light shield 3 is configured such that its projection in the vertical direction is greater than the gap between the first lamp body and the second lamp body, which will not be elaborated here.

[0071] In this embodiment, as Figure 1 and Figure 3As shown, the lamp holder 100 also includes a bracket 4, which is connected to the back of the back plate 1. The bracket 4 includes a first support portion 41 and a second support portion 42. One end of the first support portion 41 is connected to the back plate 1, and the other end of the first support portion 41 extends along the front-rear direction of the lamp holder 100. One end of the second support portion 42 is connected to the first support portion 41 and has a first distance between it and the back plate 1. The other end of the second support portion 42 is connected to the back plate 1 and is located above the first support portion 41. By setting the bracket 4 to form a triangular structure, the stability of the lamp holder 100 can be improved, and its wind resistance performance can be enhanced.

[0072] During installation, the first support portion 41 of the bracket 4 is welded to the lamp post. By connecting the bracket 4 to the lamp post, the lamp holder 100 and the lamp post can be integrated.

[0073] Specifically, there are two brackets 4, which are respectively connected to the first back plate 11 and the second back plate 12. One end of the first support part 41 is connected to the bottom of the back plate 1. The pair of triangular brackets 4 fix the first back plate 11 and the second back plate 12 at the same time to avoid torsional errors caused by unilateral welding.

[0074] The included angle between the first backplate 11 and the second backplate 12 can be set between 140° and 150°. When the included angle is less than 140°, the tip of the backplate 1 is too sharp and the stress is relatively concentrated. When the included angle is 150°, the light-blocking efficiency decreases. Therefore, setting the included angle between 140° and 150° is the optimal compromise.

[0075] Specifically, in this embodiment, the included angle between the first back plate 11 and the second back plate 12 is 145°.

[0076] Meanwhile, the first back plate 11 and the second back plate 12 are formed by bending a complete flat steel.

[0077] In this embodiment, the lamp holder 100 further includes a plurality of first reinforcing ribs 51 and a plurality of second reinforcing ribs 52. The first reinforcing ribs 51 are disposed on the layer plate 2, and the second reinforcing ribs 52 are disposed on the back plate 1. By providing the first reinforcing ribs 51 on the layer plate 2 and the back plate 1, the local rigidity of the layer plate 2 and the back plate 1 can be enhanced, thereby improving the wind resistance performance of the lamp holder 100.

[0078] Specifically, the first reinforcing rib 51 is provided along both the length and width directions of the lamp holder 100, in a cross or X-shaped arrangement. Similarly, the second reinforcing rib 52 is also provided along both the length and width directions of the lamp holder 100, and will not be described in detail here.

[0079] In this embodiment, the back plate 1 and the reinforcing ribs are made of flat steel, and the bracket 4 is made of angle steel.

[0080] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
