Problems solved by technology
Ships are generally equipped with radars, but these radars generally do not have automatic alarm devices, and cannot measure small obstacles such as reefs, boats, etc. There are generally beacon lights installed on reefs, which can indicate the direction, but not the position and distance. Therefore, Often when the ship encounters the above situation, if the driver does not pay attention to it, a collision will occur, especially the new driver has not received the alarm signal due to lack of experience, and is prone to collision accidents

The invention relates to a shipping anti-collision alarm device comprising a rotatable transmitting part, an accepting part and a sound-light alarm part, wherein the accepting part is connected with the sound-light alarm part. The shipping anti-collision alarm device is characterized in that the transmitting part consists of a rotatable base, a bracket arranged on the base, a laser and an ultrasonic transmitting head which are arranged on the bracket; the accepting part consists of a photoelectric acceptor and an ultrasonic accepting head; and the photoelectric acceptor and the ultrasonic accepting head are connected with a sound-light alarm of the sound-light alarm part. The invention has the advantages that the alarm device is safe and reliable and can alarm at once when the shipping with the alarm device approaches to another shipping or reef in the general case; the structure is simple, the cost is lower and the popularization is available; the construction and the installation are convenient, so a person without being trained can perform the construction and the installation.
Description
technical field [0001] The invention relates to a ship navigation safety alarm device, in particular to a ship anti-collision alarm device when encountering an obstacle. Background technique [0002] Ships often encounter obstacles, such as reefs, ships traveling on the other side, etc., and collisions will occur if the driver does not find out or operate improperly. When the visibility is not high (such as foggy days at night, etc.), accidents are more likely to occur. Investigations show that most of the collisions are caused by drivers not discovering obstacles in time. Ships are generally equipped with radars, but these radars generally do not have automatic alarm devices, and cannot measure small obstacles such as reefs, small boats, etc. There are generally beacon lights installed on reefs, which can indicate the direction, but not the position and distance. Therefore, Often when the ship encounters the above situation, if the driver does not pay attention to it, a c...
