This invention discloses a multifunctional fish-attracting lamp, which includes a bracket and a power supply box. The fish-attracting lamp also includes: a heat sink fixed to the end of the bracket, with a rear shell fixed to the front end of the heat sink; a cooling fan fixed in the center of the rear shell; a temperature controller fixed in one side of the heat sink fins; and a fan intelligent monitoring system embedded in one side of the rear shell. Several cooling fins are stacked from the outside to the inside at the rear end of the heat sink, and are evenly distributed circumferentially at the rear end of the heat sink. The gap between two adjacent cooling fins forms a through groove that is connected longitudinally and laterally. When the fan intelligent monitoring system detects abnormal operation of the cooling fan, it can automatically cut off the power supply to the lamp. When the temperature controller detects that the temperature of the heat sink exceeds 80°C, it can automatically cut off the power supply to the lamp. The through groove not only allows the air blown by the cooling fan to diffuse to various positions behind the heat sink, but also effectively guides water and air entering the lamp.

This invention provides a marine engine telegraph transmitter, comprising a body, a key wheel rotatably connected to the body, multiple key slots distributed around the axis of the key wheel on the side wall for corresponding different gear positions, and a key device disposed within the body that can reciprocate and rotate in conjunction with the key wheel into the key slots. The body also includes a handle capable of rotating the key wheel and a potentiometer rotatably connected to the body and rotating synchronously with the key wheel to detect the rotation angle of the key wheel. The key device includes a base fixedly installed within the body, a pin slidably connected to the base along the radial direction of the key wheel, and an elastic element disposed within the base capable of driving the pin to reciprocate. This invention achieves precise position data acquisition via the potentiometer by pulling the handle back and forth, and then achieves an elastic braking effect through the synergistic action of the spring and the pin via the key device, thereby precisely adjusting the key position.
