PURPOSE: An algal growth suppressing apparatus is provided to prevent the growth of algal by reducing intake of sunlight from downward of support stand, and the support stand unfolds horizontally under the water due to buoyancy. CONSTITUTION: An algal growth suppressing apparatus comprises the ring-shaped base frame(100), multiple support stands(200), multiple buoyancies(300), and underwater film(400). The multiple support stands are arranged around the circumference of the base frame, and hinge combined to rotatable on the base frame and connected longitudinally to be mutually detached. The multiple buoyancies are connected to each support stands, and are floated as arranged under the water with support stands and base frame. The underwater film has permeability and installed between the support stands to reduce the sunlight incidence under the water. The base frame is provided with multiple elastic wires(140) to support the elasticity while connected to the support stand under water. |
