Buoy for tracking algae

The invention provides a buoy for tracking algae, and relates to the technical field of ocean equipment. According to the buoy for tracking the algae, a sensing instrument is arranged on a buoy body, and the buoy comprises the buoy body, a supporting frame, a reverse pushing sleeve, a piston, a first reverse pushing rod, a second reverse pushing rod, a water wheel, a floating body, a transmission rod and the like. The buoy body is connected with a reverse pushing sleeve on a supporting frame through a reverse pushing rod and a piston, a water wheel is arranged in the reverse pushing sleeve, a water wheel rotating shaft is connected with a floating body through a transmission rod, and a power generation cabin and a battery cabin are arranged in the floating body. According to the buoy for tracking the algae, when stormy waves on the sea surface are large and the buoy swings greatly, the piston moves along the reverse pushing sleeve, seawater enters or is sprayed out of the reverse pushing sleeve, and the seawa
