Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge boundary lights, in particular to a bridge boundary light. BACKGROUND

[0002] In modern transportation facilities, bridges are important links connecting different regions, and their safety is crucial. In order to ensure the safe use of bridges at night or in low-visibility environments, light boxes are widely installed on bridges, among which boundary light bodies and wall washing light bodies are important components of light boxes. The boundary light body is mainly used to indicate the boundary position of the bridge for ships or other vehicles at night, forming a clear light boundary so that drivers can accurately determine the range of the bridge and avoid deviating from the channel or colliding with the bridge due to poor visibility. The wall washing light body is used to illuminate the bridge surface, not only improving the visibility of the bridge at night to facilitate vehicle and pedestrian traffic, but also beautifying the appearance of the bridge to some extent and adding color to the city night scene.

[0003] However, in practical applications, the existing light boxes have some shortcomings: When the light box is installed on the bridge, the illumination angles of the boundary light body and the wall washing light body on the light box are fixed. However, different bridge sizes and orientations are not very similar, for example, some bridges are wide, some are narrow, some are straight, some have a certain curvature, some cross rivers, and some connect mountainous areas. This results in the boundary light body and the wall washing light body with fixed illumination angles not being able to well adapt to the actual needs of different bridges. On some special orientation bridges, the boundary light body may not be able to accurately project light onto the river area that needs to be indicated, making it difficult for ship drivers to clearly determine the bridge boundary; Moreover, the light illumination range on the boundary light body cannot be adjusted, and it cannot achieve the effect of focusing light when close to the bridge and diffusing light when far from the bridge. When the boundary light body is close to the bridge, if the light cannot be focused, it will cause light dispersion and cannot form an effective warning effect in the key area; when far from the bridge, if the light cannot be diffused, the warning range will be too small, also unable to meet the safety requirements.

[0021] In this embodiment, by setting the first lead tube 10, the second lead tube 11, the connecting head 8, the traction block 12, the cross column 9, the first stop pawl 79, the second stop pawl 710, the first ratchet wheel 73, the second ratchet wheel 74 and other structures, the illumination angle of the boundary light body 17 and the wall washing light body 20 can be controlled by the lamp to the adjusting mechanism 7. Compared with the traditional fixed-angle lamps, the adaptability of the lamps to different bridge sizes and directions is greatly improved, the problem of poor illumination angle adaptation caused by bridge differences is effectively solved, and the first ratchet wheel 73 and the second ratchet wheel 74 cooperate with the first stop pawl 79 and the second stop pawl 710 to form the key structure of synchronous control of the light angle. Through the setting of different directions of them, the rotation of the boundary light body 17 and the wall washing light body 20 can be accurately controlled when the driving column 77 rotates, and the use effect of the lamps is greatly improved.

[0022] In the second embodiment, the cross column 9 is installed through the inner wall of the second gear 6, the first lead tube 10 and the second lead tube 11 are respectively arranged at one end of the connecting head 8 and the cross column 9, the traction block 12 is fixedly connected to the outer wall of one end of the connecting head 8 and the cross column 9, the first bevel gear 13 is fixedly connected to the outer wall of the first lead tube 10, the second bevel gear 14 is engaged with the outer wall of the first bevel gear 13, the lamp holder 16 is welded to the bottom outer wall of the second bevel gear 14, the boundary light body 17 is arranged at one end of the lamp holder 16, the rotating column 15 is welded to the other end of the lamp holder 16, and the end of the rotating column 15 away from the second bevel gear 14 is rotatably connected to the bottom inner wall of the lamp box 2. The guide groove 18 is arranged on the bottom of the outer wall of one side of the lamp box 2, and the lamp holder 16 is slidably connected to the inner wall of the guide groove 18.

[0023] Through the above scheme, the second gear 6 is engaged with the first gear 5, the cross column 9 rotates with the second gear 6, drives the second lead tube 11 to act, the connecting head 8 and the cross column 9 are matched with the limiting holes of the first lead tube 10 and the second lead tube 11 through the traction block 12, to ensure stable power transmission, the first bevel gear 13 of the first lead tube 10 is engaged with the second bevel gear 14 to convert the rotary motion into the swing of the lamp holder 16, the rotating column 15 ensures the stable rotation of the lamp holder 16, the guide groove 18 limits the movement track of the lamp holder 16, so that the angle and position of the boundary light body 17 are accurately controllable, and the range and angle of the light are cooperatively adjusted.

[0024] In this embodiment, the lamp holder 16 slides in the guide groove 18, which can focus the light when the boundary light body 17 is close to the bridge and diffuse the light when the boundary light body 17 is far from the bridge. When the boundary light body 17 is close to the bridge, the light can be focused in a small range through the specific position of the lamp holder 16 in the guide groove 18, which improves the light intensity and enhances the warning effect at a short distance. When the boundary light body 17 is far from the bridge, the position of the lamp holder 16 changes to diffuse the light, which expands the warning range. Thus, the different requirements for the light irradiation range of the boundary light body 17 at different distances are met, and the problem that the light irradiation range of the boundary light body 17 cannot be adjusted is solved.

[0025] In the third embodiment, the outer wall of the second lead tube 11 is welded with symmetrically distributed connecting columns 19, and the outer wall of the top of the connecting column 19 is welded with a wall washer light body 20. The outer wall of the connecting column 19 is installed with a waterproof cylinder 21, and the other side of the top of the outer wall of the lamp box 2 is provided with a top groove 22. The waterproof cylinder 21 is tightly attached to the top inner wall of the lamp box 2.

[0026] Through the above scheme, the connecting column 19 on the second lead tube 11 fixes the wall washer light body 20, so that it rotates synchronously with the second lead tube 11 to realize angle adjustment. The waterproof cylinder 21 is sleeved outside the connecting column 19 and tightly combined with the top groove 22 of the lamp box 2 to form a sealing structure, which prevents rainwater from entering the inside of the lamp box 2, protects the wall washer light body 20 and the internal circuit, and improves the waterproof level of the equipment while ensuring the angle adjustment of the wall washer light body 20, which is suitable for the outdoor environment of the bridge.

[0027] In this embodiment, the waterproof cylinder 21 always combines with the top groove 22 during the rotation of the wall washer light body 20, which has a good waterproof effect and effectively avoids the water entering the inside of the lamp during the angle adjustment of the lamp, which causes damage or failure of the lamp, improves the service life and stability of the wall washer light body 20, and ensures the continuous lighting of the bridge.

[0028] The outer wall of one side of the first rotating disc 75 and the second rotating disc 76 is welded with a clamping column 712, and the first stop pawl 79 and the second stop pawl 710 are tightly attached to the outer wall of the clamping column 712. The directions of the first stop pawl 79 and the second stop pawl 710 are opposite, and the directions of the first ratchet wheel 73 and the second ratchet wheel 74 are opposite.

[0029] Through the above scheme, the reverse-configured first ratchet 73 and second ratchet 74, as well as the first stop pawl 79 and second stop pawl 710, ensure that the drive column 77 transmits power in only one direction when it moves. The first stop pawl 79 and the second stop pawl 710 are reversed, and the first ratchet 73 and the second ratchet 74 are reversed. This ensures that when the drive column 77 rotates forward, only the second stop pawl 710 drives the second circular frame 72 to rotate, and when it rotates in reverse, only the first stop pawl 79 drives the first circular frame 71 to rotate. This avoids mutual interference when adjusting the angles of the boundary lights and wall washer lights, and ensures the independence and precision of the adjustment process.

[0030] Limiting holes are provided on the outer wall of one end of the first lead tube 10 and the second lead tube 11, and the traction block 12 is tightly attached to the inner wall of the limiting hole. The first lead tube 10 and the second lead tube 11 are both installed through the inner walls of both ends of the light box 2, and the first lead tube 10 and the second lead tube 11 are in an interference fit with the light box 2.

[0031] Through the above scheme, the interference fit between the first lead tube 10 and the second lead tube 11 and the light box 2 enhances the structural stability and prevents the first lead tube 10 and the second lead tube 11 from loosening and affecting the angle adjustment accuracy. The tight fit between the traction block 12 and the limiting hole ensures that the power of the connector 8 and the cross column 9 can be fully transmitted to the first lead tube 10 and the second lead tube 11, avoiding power loss or slippage. At the same time, it restricts the axial movement of the first lead tube 10 and the second lead tube 11, ensuring the meshing accuracy of the first bevel gear 13 and the second bevel gear 14, making the transmission efficiency of angle adjustment higher and the error smaller.

[0032] The outer walls of the drive column 77 and the cross column 9 are each provided with a pointer 23, and the outer wall of the front cover 3 on one side is provided with a scale ring 24 outside the drive column 77 and the cross column 9. The pointer 23 is located inside the scale ring 24, and a knob 25 is fixedly connected to one end of the drive column 77 near the pointer 23.

[0033] Through the above scheme, the pointer 23 on the drive column 77 and the horizontal column 9 cooperates with the scale ring 24 on the front cover 3 to provide a direct reference for angle adjustment. The operator can accurately control the rotation angle of the drive column 77 and the horizontal column 9 through the scale value pointed to by the pointer 23, so as to realize the quantitative adjustment of the boundary light body 17 and the wall washer light body 20, avoiding over-adjustment or under-adjustment. The knob 25 makes it easy to manually rotate the drive column 77, improving the convenience of operation and making the angle adjustment more accurate and efficient.

[0034] The top and bottom of one side of the outer wall of the rear cover 4 are respectively fixedly connected to the wall washer light power supply 26 and the boundary light power supply 27 by screws. The wall washer light power supply 26 and the wall washer light body 20 and the boundary light power supply 27 and the boundary light body 17 are connected by signal lines. The outer walls of one side of the wall washer light power supply 26 and the boundary light power supply 27 are fixedly connected to cables 28, and one end of the cable 28 is provided with a wire connector 29 on its outer wall.

[0035] Through the above scheme, the wall washer light power supply 26 and the boundary light power supply 27 on the rear cover 4 provide power to the wall washer light body 20 and the boundary light body 17, respectively. The signal line realizes the linkage control between the wall washer light power supply 26 and the boundary light power supply 27, controlling the start and stop of the wall washer light body 20 and the boundary light body 17. The cable 28 and the wire connector 29 facilitate the connection to the external power supply, simplifying the installation process.

[0036] The outer wall of the other side of the light box 2 is fixedly connected with symmetrically distributed corner brackets 30 by screws, and the bottom outer wall of the corner brackets 30 is fixedly connected with a support frame 31 by screws. The outer wall of one side of the support frame 31 is fixedly connected to the outer wall of the bridge body 1 by screws.

[0037] With the above solution, the light box 2 is connected to the support frame 31 via the corner bracket 30, and the support frame 31 is fixed on the main body of the bridge 1 to form a stable installation structure.

[0038] Working principle: First, the light box 2 is installed and fixed: the front cover 3 is fixed to one end of the light box 2 with screws, so that the traction block 12 on the connector 8 and the cross column 9 are respectively embedded in the limiting holes of the first lead tube 10 and the second lead tube 11 to achieve a preliminary mechanical connection. Then, the rear cover 4 with the wall washer power supply 26 and the boundary light power supply 27 is fixed to the other end of the light box 2 to complete the power supply assembly. Finally, the light box 2 is fixed to the bridge body 1 by the corner bracket 30 and the support frame 31 to ensure the stability of the overall structure. After the power is turned on, the wire connector 29 is connected to the external power. The wall washer light power supply 26 and the boundary light power supply 27 supply power to the wall washer light body 20 and the boundary light body 17 respectively through the signal line. When both are lit, the boundary light body 17 illuminates the river surface to form a boundary, and the wall washer light body 20 illuminates the bridge surface, playing a basic lighting warning role. When adjusting the angle of the boundary light body 17, the drive column 77 is rotated, which drives the first rotating disk 75 and the second rotating disk 76 to rotate. Since the first stop pawl 79 and the second stop pawl 710, as well as the first ratchet 73 and the second ratchet 74, are in opposite directions, the first stop pawl 79 cannot drive the first circular frame 71, while the second stop pawl 710 drives the second circular frame 72 to rotate, thereby causing the first lead tube 10 to rotate. The first bevel gear 13 on the first lead tube 10 meshes with the second bevel gear 14, thereby driving the lamp holder 16 and the boundary light body 17 to rotate. At the same time, the lamp holder 16 slides in the guide groove 18, achieving the effect of focusing the light when it is close and diffusing it when it is far away. When adjusting the angle of the wall washer light body 20, the drive column 77 is rotated in the opposite direction. At this time, the first stop pawl 79 drives the first circular frame 71 and the first gear 5 to rotate. The first gear 5 meshes with the second gear 6, causing the horizontal column 9 and the second lead tube 11 to rotate. This drives the wall washer light body 20 to rotate through the connecting column 19. During this process, the waterproof sleeve 21 rotates with the connecting column 19 in the top groove 22 and remains in contact, thus providing waterproofing. In addition, the position of the boundary light body 17 and the wall washer light body 20 can be determined by the angle of the pointer 23 pointing to the scale ring 24, ensuring accurate adjustment.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
