Description
Technical Field
[0001] This utility model relates to the field of ship navigation and safety equipment technology, and in particular to an automatic adjustment device for the angle of lights on a marine vessel. Background Technology
[0002] In maritime operations, the ship's lighting system is one of the core devices for ensuring navigational safety. It mainly performs three key functions: First, navigational identification, which uses the position and angle of specific lights such as sidelights, stern lights, and mast lights to convey key information such as the ship's course, speed, and navigation status to surrounding vessels, thus avoiding collisions; second, environmental lighting, which provides a clear view for deck operations and sea surface observation through equipment such as deck lights and searchlights; and third, emergency signaling, which transmits distress or warning signals through changes in the frequency and angle of light flashing in special scenarios such as distress or malfunction.
[0003] However, existing marine lighting control devices generally suffer from the following technical defects, making it difficult to meet the intelligent and safe navigation requirements of modern ships:
[0004] Most existing ship lights use manual mechanical adjustment mechanisms, requiring crew members to manually tighten adjustment bolts or rotate brackets on deck to change the light angle. In severe sea conditions (such as strong winds, large waves, heavy rain, and dense fog), the deck working environment is complex and dangerous, and crew members are prone to falling due to ship pitching and rolling. This not only results in low adjustment efficiency but also poses personal safety hazards. Furthermore, manual adjustment relies on crew experience, making it difficult to achieve precise angle control and easily leading to deviations in light signal transmission.
[0005] During navigation, the surrounding environment (such as changes in the course of other vessels, the appearance of obstacles on the sea surface, and the ship's tilt caused by sea conditions) and operational needs (such as deck loading and unloading, and maritime search and rescue) change in real time. However, existing devices are mostly designed with fixed angles or only support single-dimensional adjustment (such as horizontal rotation only), and cannot simultaneously adjust the horizontal rotation angle, pitch angle, and lamp spacing of the lights. For example, when a ship experiences rolling, the fixed-angle lights will create blind spots due to the ship's tilt; when surrounding vessels approach, the signal light angles cannot be quickly adjusted to accurately transmit avoidance signals, increasing navigational risks.
[0006] In summary, existing marine lighting adjustment devices have significant shortcomings in terms of automation, dynamic adaptability, operational safety, and structural stability, and cannot meet the needs of modern ships for efficient, safe, and intelligent navigation. Developing a lighting angle adjustment device with dynamic recognition, multi-dimensional automatic adjustment, and high stability has become an urgent need in the field of marine equipment.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] Reference Figures 1-3 This utility model provides an automatic adjustment device for the angle of marine lights, comprising:
[0032] Base 1, with a linear motion component mounted on its top surface;
[0033] A rotating component is mounted on a linear motion component, and a mounting base 2 is mounted on the top of the rotating component;
[0034] The tilt adjustment mechanism is mounted on the mounting base 2, and the tilt adjustment mechanism is mounted on the boom 3. The end of the boom 3 is mounted on the mounting plate 4.
[0035] The spacing adjustment component is mounted on the mounting plate 4. Two sets of mounting blocks 17 are mounted on the spacing adjustment component. The marine lights are mounted on the mounting blocks 17 through positioning plates.
[0036] A dynamic identification sensor is mounted on mounting plate 4.
[0037] The controller, linear motion component, rotation component, tilt adjustment mechanism, spacing adjustment component, and dynamic identification sensor are all connected to the controller.
[0038] After the device is activated, the crew can input the ship type, current navigation mission, and lighting type (such as navigation lights and searchlights) through the controller. Based on a preset ship equipment database, the controller automatically loads the initial parameters for the corresponding scenario, including the horizontal rotation reference angle of the lights, the initial value of the pitch angle, and the standard value of the light spacing. At the same time, the linear motion components, rotation components, and other actuators complete self-checks to ensure that all components are in a ready-to-operate state. The dynamic recognition sensors installed on the mounting plate 4 continuously collect multi-dimensional environmental and ship status data, including: surrounding ship information: capturing the heading, speed, and distance of surrounding ships through image recognition or radar signals to determine whether there is any potential risk; sea state and ship attitude: detecting the ship's roll and pitch angles through tilt sensors and obtaining real-time wind speed through wind speed sensors; visibility and lighting requirements: determining low visibility environments such as nighttime and foggy days through photosensitive sensors, and determining whether the lighting coverage needs to be adjusted through image recognition of the deck working area. After receiving sensor data, the controller performs logical calculations based on preset parameters and international navigation rules (such as the requirements for navigation light angles in the International Maritime Collision Prevention Regulations), generates adjustment commands, and sends them to each execution component: if a surrounding vessel is detected approaching from the left, the controller commands the rotating component to rotate the mounting base 2, so that the port side light's illumination angle is precisely aligned with the direction of the approaching vessel; if the vessel rolls, causing the light to deviate, the rotating component compensates for the rotation angle in real time to maintain a stable illumination direction.
[0039] When ship pitching causes blind spots in deck lighting, the tilt adjustment mechanism drives the boom 3 to swing up and down, adjusting the pitch angle of the lamps to ensure lighting coverage of the deck work area. In search and rescue scenarios, the controller instructs the tilt adjustment mechanism to adjust the search light tilt angle to the optimal detection angle based on the target's landing point. If it is necessary to switch signal light modes (such as from "navigation light" to "anchor light"), the spacing adjustment component drives the two sets of mounting blocks 17 to slide along the mounting plate 4, adjusting the lamp spacing to meet the standard of the corresponding signal mode. If different sizes of lamps are used, the spacing adjustment component can flexibly adjust the position of the mounting blocks 17 to ensure the lamps are stably fixed. When the ship's deck work area changes, the linear motion component drives the entire rotating component and the tilt adjustment mechanism to slide along the base 1, moving the lamps to a position closer to the work area to improve lighting efficiency. During the adjustment process, the dynamic identification sensor continuously monitors the lighting effect and environmental changes. If it detects that the lighting blind spot has not been eliminated or the signal light angle is not aligned with the approaching ship, the sensor will transmit the feedback data to the controller. The controller will then issue a fine-tuning command until the lighting status meets the navigation or operation requirements, forming a closed-loop control of "monitoring-adjustment-feedback".
[0040] The scheme is further optimized. The linear motion component includes a linear motor 5, which is fixed on the base 1, and the rotation component is mounted on the slide of the linear motor 5.
[0041] The scheme is further optimized. The rotating component includes a support platform 6, which is fixed on the slide of the linear motor 5. A turntable 7 is rotatably connected to the top surface of the support platform 6. The turntable 7 is fixed to the bottom surface of the mounting base 2. A rotary motor 8 is fixed on the support platform 6. A worm gear is fixed to the output shaft of the rotary motor 8. A mounting shaft is fixed to the bottom of the turntable 7. A worm wheel is fixed on the mounting shaft. The worm wheel and the worm gear are connected by a transmission mechanism.
[0042] The rotating assembly adopts a "motor-worm gear" reduction transmission structure, with the core power source being a rotary motor 8 fixed on the support platform 6. When the controller needs to adjust the horizontal rotation angle of the lamp (e.g., aligning with the direction of an approaching vessel), the rotary motor 8 receives the command and starts, its output shaft driving the worm gear to rotate synchronously. Because the worm gear meshes with the worm wheel on the mounting shaft at the bottom of the turntable 7, and the worm gear transmission has the characteristics of speed reduction and torque increase, and reverse self-locking, the rotational force of the worm gear is converted into the low-speed rotational motion of the worm wheel. The worm wheel is fixed on the mounting shaft, which is rigidly connected to the turntable 7. Therefore, when the worm wheel rotates, it drives the turntable 7 to rotate around the rotation center of the top surface of the support platform 6. The top of the turntable 7 is fixed to the mounting base 2, ultimately driving the mounting base 2 and the tilt adjustment mechanism and lamp above it to rotate synchronously, achieving stable adjustment of the lamp's horizontal angle. The self-locking characteristic can prevent angle deviation caused by ship turbulence.
[0043] Further optimizing the scheme, the tilt adjustment mechanism includes an electrically controlled telescopic rod 9, which is rotatably connected to the top surface of the mounting base 2. A first link group 10 is rotatably connected to the mounting base 2. The first link group 10 has an H-shaped structure, and its top is rotatably connected to the middle position of the boom 3. A second link group 11 is rotatably connected to the output end of the electrically controlled telescopic rod 9. The second link group 11 has a T-shaped structure, and a first connecting rod 12 is rotatably connected to one end of the second link group 11. The first connecting rod 12 is rotatably connected to the rear end of the boom 3. The bottom of the second link group 11 is rotatably connected to the mounting base 2. A second connecting rod 13 is rotatably connected to the crossbar of the first link group 10, and one end of the second connecting rod 13 is rotatably connected to the second link group 11.
[0044] When the telescopic pole extends or retracts, its output end pushes or pulls the second linkage group 11 of the T-shaped structure, causing the second linkage group 11 to rotate around the rotation point of the bottom and the mounting base 2; one end of the second linkage group 11 is rotatably connected to the rear end of the boom 3 through the first connecting rod 12, and pushes and pulls the rear end of the boom 3 synchronously; at the same time, the second linkage group 11 is linked with the crossbar of the H-shaped first linkage group 10 through the second connecting rod 13, driving the first linkage group 10 to rotate around the rotation point of the bottom and the mounting base 2;
[0045] The top of the first linkage group 10 is rotatably connected to the middle position of the boom 3, forming a "middle support + rear push and pull" synergistic effect on the boom 3, causing the boom 3 to swing up and down around the rotation point at the top of the first linkage group 10; the lamp is installed at the end of the boom 3, ultimately achieving a smooth adjustment of the lamp's pitch angle. The double linkage group structure can prevent the boom 3 from swaying and ensure adjustment accuracy.
[0046] The scheme is further optimized. The spacing adjustment component includes a fixed base 14, which is fixed on the mounting plate 4. A spacing adjustment motor is fixedly connected to the fixed base 14. The output shaft of the spacing adjustment motor is fixedly connected to a bidirectional lead screw 15. Two sets of sliders 16 are threadedly connected to the bidirectional lead screw 15. The two sets of sliders 16 are symmetrically slidably connected to the fixed base 14. Mounting blocks 17 are respectively installed on the sliders 16.
[0047] The spacing adjustment assembly uses a "motor-bidirectional lead screw 15" as its core transmission structure, with the power source being a spacing adjustment motor fixed on the mounting plate 4. When the controller needs to adjust the spacing between two sets of lights (such as switching between navigation light / anchor light modes), the spacing adjustment motor receives the command and starts, and its output shaft drives the bidirectional lead screw 15 (with opposite thread directions at both ends) to rotate; the two sets of sliders 16 respectively engage with the threads at both ends of the bidirectional lead screw 15, and the sliders 16 are slidably connected to the fixed base 14 via guide rails (restricting rotational freedom); when the bidirectional lead screw 15 rotates, the axial force generated by the reverse threads causes the two sets of sliders 16 to slide synchronously towards each other (spacing decreases) or in the opposite direction (spacing increases) along the fixed base 14; the mounting block 17 is fixed on the sliders 16, and the lights are mounted on the mounting block 17 via positioning plates, so when the sliders 16 move, they drive the two sets of lights to adjust their spacing synchronously, achieving the adaptation requirements of different signal modes or light sizes.
[0048] The design was further optimized so that the mounting block 17 was mounted on the slider 16 via a positioning universal joint, and the positioning plate was fixed to the mounting block 17 with bolts.
[0049] The positionable universal joint is a multi-degree-of-freedom rotation structure. First, loosen the universal joint locking component, and then adjust the spatial angle of the mounting block 17 through the universal joint so that the lamp is initially aligned with the target illumination direction.
