Abstract
Description
Technical Field
[0001] This utility model relates to the field of underwater split-type lights, and in particular to an underwater split-type light for nuclear environments. Background Technology
[0002] Underwater split lights are lighting devices specifically designed for underwater environments, widely used in diving, marine exploration, underwater operations, and underwater photography. Their unique split design separates the main body of the light from the battery, allowing the battery and lamp head to connect via a waterproof cable. This not only improves the convenience and safety of the light but also allows for battery or lamp head replacement as needed, extending its lifespan. Underwater split lights typically use high-brightness LED light sources, providing powerful illumination. Their housings are generally made of aluminum alloy or stainless steel, offering excellent waterproof performance and corrosion resistance, and capable of withstanding high water pressure. The brightness, color temperature, and beam angle of the light can be adjusted according to actual needs, ensuring clear illumination of target areas even in complex underwater environments. Overall, underwater split lights, with their high efficiency and flexibility, have become an indispensable lighting tool for underwater operations.
[0003] For example, an LED lamp with motor-adjustable angle, application number CN202321069402.8, includes the following technical features: a mounting shaft, a drive mechanism, and a lamp assembly. The drive mechanism is mounted on the mounting shaft and is used to drive the lamp assembly to rotate. The drive mechanism includes: a first housing, rotatably mounted on the mounting shaft; a first drive assembly, disposed within the first housing and connected to the first housing via a transmission connection, used to drive the first housing to rotate along the central axis of the mounting shaft; a connecting assembly, mounted on the first housing; a second housing, rotatably mounted on the connecting assembly, with the lamp assembly disposed on the second housing; and a second drive assembly, disposed within the second housing, with a second transmission assembly connected to the second housing via a transmission connection, used to drive the second housing to rotate along a first direction, the first direction being perpendicular to the central axis of the mounting shaft.
[0004] The aforementioned underwater split lights are designed for use in underwater environments and require prolonged operation for illumination, which generates a significant amount of heat. Additionally, the need to adjust the angle, especially with frequent adjustments, also generates considerable heat from the motor. This accumulated heat, if not dissipated, can lead to damage to the lights.
[0005] Therefore, a split underwater lamp for nuclear environments is proposed to solve or alleviate the above problems. Utility Model Content

[0018] In application of this invention, the heat dissipation shaft guides the heat from the lamp holder to diffuse outwards, while the heat dissipation arc and heat dissipation mesh assist in heat dissipation. When the temperature sensor detects that the temperature has reached a threshold, the trigger circuit turns on the transistor, energizing the traction electromagnet to pull the sealing block, allowing water to enter the upper heat dissipation pipe and exchange heat with the heat dissipation connecting shell, thus preventing damage to the lamp body. When the temperature falls below the threshold, the traction electromagnet is de-energized, and the sealing block re-seals the connection point, maintaining a tight seal. Attached Figure Description

The outer ring of the lower lamp holder 2 is rotatably connected to a heat dissipation lower rotating pipe 8 communicating with it. The outer ring of the upper lamp holder 6 is rotatably connected to a heat dissipation upper rotating pipe 10 communicating with it. The heat dissipation upper rotating pipe 10 and the heat dissipation lower rotating pipe 8 are rotatably connected to a heat dissipation connecting shell 9 communicating with both of them. The side of the heat dissipation connecting shell 9 away from the heat dissipation upper rotating pipe 10 is connected to an inlet pipe 11. A heat dissipation shaft 12 is rotatably connected inside the heat dissipation lower rotating pipe 8. A sealed bearing 15 is fixedly connected inside the heat dissipation lower rotating pipe 8. The heat dissipation shaft 12 is fixedly connected to the inner ring of the sealed bearing 15. A heat dissipation mesh 14 is provided inside the heat dissipation connecting shell 9. The heat dissipation shaft 12 and the heat dissipation mesh 14 are fixedly connected through a heat dissipation arc 13. The heat dissipation shaft 12, the heat dissipation arc 13, and the heat dissipation mesh 14 are all made of copper. A sealing block 17 is slidably connected inside the heat dissipation upper rotating pipe 10 and the inlet pipe 11.
[0032] A drive assembly is provided inside the heat dissipation tube 10. The movable end of the drive assembly can be moved back and forth, and the movable end of the drive assembly is fixedly connected to the blocking block 17. The drive assembly includes a traction electromagnet 16.
[0033] A temperature control circuit is installed inside the lower lamp holder 2. The temperature control circuit is coupled to the traction electromagnet 16. The temperature control circuit controls the traction electromagnet 16 to turn on and off according to the ambient temperature inside the lower lamp holder 2. The temperature control circuit includes a temperature sensor, a voltage comparator circuit, a trigger circuit, and a switching circuit. The probe of the temperature sensor is installed inside the lower lamp holder 2. The output terminal of the temperature sensor is coupled to the input terminal of the voltage comparator circuit. The output terminal of the voltage comparator circuit is coupled to the input terminal of the trigger circuit. The output terminal of the trigger circuit is coupled to the controlled terminal of the switching circuit. The power terminal of the switching circuit is coupled to the power supply. The output terminal of the switching circuit is coupled to the traction electromagnet 16. The voltage comparator circuit includes a minimum circuit based on the voltage comparator LM393. The trigger circuit includes an RS trigger. The switching circuit includes a transistor switch. The base of the transistor switch is the controlled terminal of the switching circuit. The collector of the transistor switch is the power terminal of the switching circuit. The output terminal of the transistor switch is the emitter of the switching circuit.
[0034] It also includes a through-line transfer tube 3 that is rotatably connected to and communicates with the outer ring of the lower lamp holder 2, an through-line transfer tube 5 that is rotatably connected to and communicates with the outer ring of the upper lamp holder 6, and a through-line connecting shell 4 that is rotatably connected to and communicates with the through-line transfer tube 3 and the through-line transfer tube 5.

[0036] In practical application, this invention guides the heat inside the lower lamp holder 2 to diffuse outward through the heat dissipation shaft 12, and then guides the heat outward through the heat dissipation arc 13 and heat dissipation mesh 14. If the temperature sensor in the temperature control circuit detects that the temperature inside the lower lamp holder 2 has reached a threshold, the temperature signal output by the temperature sensor is sent to the voltage comparison circuit. Since the temperature reference signal in the voltage comparison circuit is less than the temperature signal, it outputs a comparison signal to the trigger circuit. The trigger circuit, in response to the comparison signal, outputs a trigger signal to the base of the transistor switch. This allows the collector and emitter of the transistor switch to conduct, thereby energizing the traction electromagnet 16, which then pulls the sealing block. 17, so that the sealing block 17 no longer blocks the connection between the heat dissipation upper rotating pipe 10 and the heat dissipation connecting shell 9, allowing external water to enter the heat dissipation upper rotating pipe 10 and the heat dissipation connecting shell 9, thereby allowing the water to come into contact with the heat dissipation arc 13 and the heat dissipation mesh 14 for heat exchange. This allows the heat in the lower lamp holder 2 to continuously exchange heat from the heat dissipation shaft 12, the heat dissipation arc 13, and the heat dissipation mesh 14, preventing damage to the lamp body inside the lamp housing 1. When the temperature drops below the threshold, the traction electromagnet 16 can be de-energized, causing the sealing block 17 to shift again and block the connection between the heat dissipation upper rotating pipe 10 and the heat dissipation connecting shell 9, preventing excessive external water pressure from continuously affecting the sealing of the internal structure of the split lamp.
[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
