Description

Technical Field

[0001] The utility model belongs to the technical field related to marine lighting equipment, and in particular relates to a focusing device for a sea sweeping lamp. Background Art

[0002] Traditional marine lighting equipment usually has technical bottlenecks such as inconvenient focusing, limited lighting range, low heat dissipation efficiency, and insufficient waterproof and anti-corrosion performance. These problems seriously restrict the effectiveness of marine lighting equipment, especially in the complex and changeable marine environment, which puts higher requirements on the stability and reliability of lighting equipment. With the development of marine engineering, navigation safety, and maritime rescue, the performance requirements for marine lighting equipment are constantly increasing, and a new, high-performance sea sweeping light focusing device is urgently needed to meet these growing industry needs.

[0003] Traditional sea sweeping lights usually rely on manual operation for focusing, which is not only inefficient but also difficult to implement in bad weather conditions, affecting the real-time adjustment of lighting effects. In addition, the lack of automatic focusing function also means that the focus and scattering of light are difficult to be effectively controlled at different illumination distances. Marine lighting equipment works at high intensity for a long time, which will generate a lot of heat. If the heat dissipation is not good, it will cause the equipment to overheat, affecting its stability and service life. Traditional heat dissipation design is often not enough to meet this challenge. Factors such as high salinity, humidity, and wind and waves in the marine environment pose a severe test to the materials and structures of lighting equipment. Traditional waterproof and anti-corrosion measures are often not perfect, and it is easy to cause equipment damage or performance degradation. In order to improve the lighting effect, it is necessary to optimize the optical design to achieve more precise beam control and better lighting coverage. However, traditional optical systems often cannot meet these requirements.

[0004] In response to the problems and challenges in the above technical background, this patent proposes a new type of sea-sweeping lamp focusing device, which realizes active and automatic adjustment of the light focus by integrating a focusing motor and a linkage push-pull rod, and improves the flexibility and accuracy of focusing. The heat generated by the light generator is effectively managed by a heat dissipation mechanism and a heat dissipation fan, ensuring the long-term stable operation of the device. The focusing and focus adjustment of the light are achieved through the precise matching of the rear lens and the front lens, ensuring the clarity and brightness of the lighting effect. The use of measures such as a waterproof cover effectively prevents the erosion of seawater and rainwater and extends the service life of the device. The entire device is compactly designed, and the various components operate in coordination, reducing space occupancy and facilitating installation and maintenance. The device can automatically adjust the focal length according to the rotation angle of the lamp housing, reducing manual intervention and improving work efficiency and safety. Through the introduction of these innovative technologies, the sea-sweeping lamp focusing device proposed in this patent has shown significant technical advantages and application potential in the field of marine lighting, providing a strong guarantee for the safety and efficiency of marine operations.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-Figure 4The focusing device of a sea sweeping lamp shown in the figure comprises a base 1, a transverse rotating seat 2 is arranged at the center of the upper end of the base 1, the transverse rotating seat 2 is rotatably connected to the upper end of the base 1 through a rotating motor arranged inside the base 1, and can drive a lamp housing 6 to rotate through a transverse adjustment frame 3, so that the lamp housing 6 can perform transverse sea sweeping illumination, a telescopic seat 4 is penetrated from top to bottom inside the upper end of the transverse rotating seat 2 and the lower end of the transverse adjustment frame 3, and the telescopic seat 4 is slidably connected to the lower end of the transverse rotating seat 2 and the transverse adjustment frame 3 through the telescopic motor inside the base 1, and The protrusion is connected to the vertical adjustment frame 5 on the upper side of the inner wall at the lower end of the horizontal adjustment frame 3, and the telescopic seat 4 can control the vertical adjustment frame 5 to move up and down by telescoping. Since the connection between the horizontal adjustment frame 3 and the lamp housing 6 is located at the center of the left and right ends of the lamp housing 6, the connection between the vertical adjustment frame 5 and the lamp housing 6 is located at the rear side of the center of the left and right ends of the lamp housing 6, and the telescopic seat 4 is rotatably connected to the vertical adjustment frame 5, so that the vertical adjustment frame 5 can be adjusted between the telescopic seat 4 and the lamp housing 6. Therefore, the telescopic seat 4 can control the lamp housing 6 to move around the horizontal through the vertical adjustment frame 5. The connection between the adjustment frame 3 and the lamp housing 6 is rotated so that the lamp housing 6 can perform vertical long and short sea sweeping illumination. A heat dissipation mechanism 7 is arranged at the rear side of the upper end of the lamp housing 6, and the heat dissipation mechanism 7 is communicated with the interior of the lamp housing 6. A heat dissipation fan is arranged inside the heat dissipation mechanism 7. A light generator 8 is arranged inside the rear end of the lamp housing 6. A heat sink 9 is arranged outside the light generator 8. The sea sweeping lamp provides illumination through the light generator 8, and the light generator 8 dissipates heat through the heat sink 9, and the heat is conducted out of the lamp housing 6 through the heat dissipation mechanism 7, ensuring that the light generator 8 In order to ensure stable operation, a rear lens 10 is arranged at the front end of the light generator 8, a front lens 11 is arranged inside the front end of the lamp housing 6, a protective mirror 12 is arranged on the front side of the front lens 11, and the protective mirror 12 is fixedly connected to the front end of the lamp housing 6. The light generator 8 can focus the light of the light generator 8 through the cooperation of the rear lens 10 and the front lens 11, and can adjust the position of the irradiation focus by adjusting the distance between the rear lens 10 and the front lens 11, and the protective mirror 12 can block the front end of the lamp housing 6, thereby protecting the inside of the lamp housing 6.

[0028] Preferably, an inner support frame 13 is provided on the rear side of the front lens 11, and a focusing motor 14 is fixedly connected to the rear end of the inner support frame 13. A focusing screw 15 is rotatably connected to the front end of the focusing motor 14, and the focusing screw 15 passes through the front side of the inner support frame 13 forward. A focusing screw sleeve 16 is threadedly connected to the front external side of the focusing screw 15, and the focusing screw sleeve 16 is fixedly connected to the lower end of the front lens 11. The focusing motor 14 drives the focusing screw 15 to rotate, so that the focusing screw sleeve 16 moves back and forth outside the focusing screw 15, and the focusing screw sleeve 16 then drives the front lens 11 to move back and forth inside the front end of the lamp housing 6, and limits the moving position through the limit support seat 17 at the lower end of the front lens 11, so that the front lens 11 can move back and forth stably and always maintain the same central axis as the rear lens 10, thereby adjusting the distance between the rear lens 10 and the front lens 11, and then adjusting the focus of the sea-sweeping lamp, so that the sea-sweeping lamp can adjust the focal length.

[0029] like Figure 3-Figure 6 As shown, linkage connecting rods 18 are fixedly connected to the left and right sides of the upper end of the inner support frame 13, and focusing slide bars 19 are fixedly connected to the upper ends of the two linkage connecting rods 18. Focusing slide grooves 20 are opened inside the front sides of the centers of the left and right ends of the lamp housing 6, and the two focusing slide bars 19 are slidably connected inside the two focusing slide grooves 20 respectively, so that the inner support frame 13 can be connected to the lamp housing 6 through the linkage connecting rod 18 and the focusing slide bar 19, and can be slidably connected inside the lamp housing 6 through the focusing slide bar 19 and the focusing slide groove 20.

[0030] Preferably, the focusing slide bar 19 is arranged in an inverted "U" shape, so that the end of the focusing slide bar 19 close to the linkage connecting rod 18 is located inside the lamp housing 6, and the end of the focusing slide bar 19 away from the linkage connecting rod 18 is located outside the lamp housing 6, and the lower end of the focusing slide bar 19 is fixedly connected to a connecting swivel seat 21 away from the linkage connecting rod 18.

Therefore, the connection between the linkage push-pull rod 22 and the linkage support rod 23 is located on the upper sides of the left and right ends of the lamp housing 6, so that when the lamp housing 6 rotates downward from the horizontal state around the connection between the lateral adjustment frame 3 and the lamp housing 6, the light irradiated by the sea sweeping lamp will move from far away to near, and at the same time, the linkage push-pull rod 22 will pull the focusing slide bar 19 backwards, so that the focusing slide bar 19 slides backward in the focusing slide groove 20, so that the inner support frame 13 slides backward in the lamp housing 6, thereby driving the front lens 11 to approach the rear lens 10, so that the focus of the sea-sweeping lamp can be automatically adjusted to the near side when the light of the sea-sweeping lamp moves from far to near. Conversely, when the light of the sea-sweeping lamp moves from near to far, the linked push-pull rod 22 will push the focusing slide bar 19 to slide forward in the focusing slide groove 20, so that the inner support frame 13 drives the front lens 11 away from the rear lens 10, so that the focus of the sea-sweeping lamp can be automatically adjusted to the far side when the light of the sea-sweeping lamp moves from near to far, so that the sea-sweeping lamp can not only actively adjust the focus of the light by driving the focusing screw 15 to rotate through the focusing motor 14, but also drive the focusing slide bar 19 to slide through the linked push-pull rod 22, and the focusing slide bar 19 then drives the movement of the inner support frame 13 and the front lens 11 to automatically adjust the focus of the light, thereby ensuring the illumination brightness and illumination clarity of the sea-sweeping lamp at far and near.

[0031] Preferably, a waterproof cover is fixedly connected to the outer side of one end of the focusing slide 20 away from the lamp housing 6, and the opening of the waterproof cover is downward, which does not hinder the sliding of the focusing slide 19 inside the focusing slide 20. At the same time, the waterproof cover is located on the side of the linkage push-pull rod 22 close to the lamp housing 6, and is located on the upper side of the connecting swivel 21, so that the waterproof cover does not hinder the connection between the connecting swivel 21 and the linkage push-pull rod 22, and is used to prevent rainwater and seawater from entering the interior of the lamp housing 6 from the focusing slide 20, ensuring that the sea-sweeping lamp can operate stably.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
