The invention relates to a multifunctional shallow
water barrier. The multifunctional shallow
water barrier comprises a
pile body, a function cabin, a power generation cabin and a
water turbine; the function cabin is arranged on the top of the
pile body, the power generation cabin and the
water turbine are arranged along the
pile body, the function cabin comprises a warning lamp used for warning,the power generation cabin comprises a
magnet and a coil, the coil cuts a magnetic induction line to generate power, the
water turbine comprises a
clockwise vertical shaft water
turbine capable of rotating
clockwise around the pile body and an anticlockwise vertical shaft water
turbine capable of rotating anticlockwise around the pile body, the
clockwise vertical shaft water
turbine and the anticlockwise vertical shaft water turbine drive the
magnet and the coil to oppositely rotate, and the warning lamp supplies power through the power generation cabin. The characteristic that the offshore
shallow water area is not uniform in water current direction distribution, and water current direction distribution is changeable is used sufficiently, energy capturing and converting can be independently carried out, multiple ocean warning and observing devices are carried out, and multiple functions of sea area use division, area warning, sea
information monitoring and
data transmission are achieved at the same time.
