A motorcycle lamp with a heat dissipation structure
This utility model discloses a motorcycle lamp with a heat dissipation structure, including a lamp housing, an LED lamp assembly, a reflector, and a lens. The lamp housing consists of a detachable rear housing and a front housing. The reflector and lens are located in the front housing, and the LED lamp assembly is located in the reflector. Addressing the issues of limited space in motorcycle lamp covers and difficulty in heat dissipation for LED lamps, a lamp housing cooling fan is located at the rear end of the rear housing, while a vent and a movable cover are located on the lower front side. The fan's forced airflow and directional air circulation quickly remove heat from the LED lamps, controlling the lamp body temperature and preventing a decrease in luminous efficiency due to high temperatures, thus ensuring stable brightness. The movable cover allows for flexible opening and closing of the vent, balancing heat dissipation efficiency with protection against harsh environments, preventing moisture and dust from entering. This solves the problems of halogen lamps being prone to burnout and LED lamps having poor heat dissipation, improving driving safety. The detachable housing is suitable for small installation spaces, eliminating the need to completely disassemble the lamp cover during maintenance; only the front housing needs to be removed, simplifying the process and reducing costs.

A full-depth anti-stall underwater cutting device
This application provides a full-ocean-depth anti-stagnation underwater cutting device, belonging to the field of underwater device engineering application technology. It includes a drive unit, an inner magnetic coupler, an outer magnetic coupler, and a saw blade. The inner magnetic coupler is rigidly connected to the drive shaft. The inner and outer magnetic couplers transmit torque non-contactly through a magnetic field generated by a magnet, causing the saw blade and outer magnetic coupler to rotate synchronously for cutting. When the saw blade suddenly stops (stagnates) during underwater operation due to unexpected situations such as cutting foreign objects or getting stuck in gaps, the outer magnetic coupler stops rotating along with the saw blade. Since there is no rigid mechanical connection between the inner and outer magnetic couplers, only the shearing force of the magnetic field exists. At this time, the inner magnetic coupler and the drive shaft can continue to idle or rotate at low speed even when the outer magnetic coupler is stopped. This avoids stall damage to the drive unit caused by a sudden increase in load, such as overcurrent, overheating, or burnout, thus improving the reliability, durability, and safety of the cutting device in unpredictable and complex underwater environments.
