PURPOSE: An oxygen supply device of a fish farm using a pumping power is provided to supply oxygen to the fish farm in an environment-friendly manner without using additional energy by supplying water to the fish farm while oxygen is dissolved in the water as the water is sprayed while rotating a fan including a nozzle by using pumping power of a pump that supplies the water to the fish farm, and the water drops sprayed from the nozzle contact air. CONSTITUTION: An oxygen supply device of a fish farm using a pumping power comprises a fish farm water supply pipe(102), a fan(200), and an oxygen dissolving chamber(300). The fish farm water supply pipe supplies water to the fish farm through a pump. The fan is installed at an end side of the fish farm water supply pipe, and comprises a cylindrical body(201) installed in a rotatable state at an end part of the fish farm water supply pipe, multiple wings(202) that are installed on and connected to an outer periphery of the body, and multiple nozzle(203) that are formed in the body and the wings, include pathways connected to the fish farm water supply pipe to spray the supplied water, and apply a rotating power to the body and the wings by the pumping power of the pump to induce air therein. The oxygen dissolving chamber is formed in a pipe shape having a predetermined space unit, and the fan is installed in the space. |
