Multifunctional ecological environment-friendly aquatic animal and plant cultivation tank

Abstract

The invention relates to a multifunctional ecological environment-friendly aquatic animal and plant cultivation tank, and belongs to the technical field of aquatic animal and plant cultivation equipment. The multifunctional ecological environment-friendly aquatic animal and plant cultivation tank comprises a fish tank, a rope, a floating block and a balloon, wherein a cavity is fixedly formed in the upper end surface of the fish tank, a first opening is formed in the side edge of the cavity, a whistle is fixedly arranged at one end of the first opening and located outside the cavity, an opening of the balloon is fixedly connected with the other end of the first opening, the balloon is located inside the cavity, and a second opening is formed in the bottom end face of the cavity; and the cavity communicates with the fish tank through the second opening, a deflation valve is arranged at the second opening, and a balancing weight is connected to the deflation valve through the rope. The multifunctional ecological environment-friendly aquatic animal and plant cultivation tank can be used for aquaculture and can also be used as a teaching aid for teaching through lively activities. On one hand, biological knowledge can be learned through ecological cultivation of animals and plants, and on the other hand, physical knowledge such as buoyancy, gravity, air pressure, force transmission, elastic force, sound waves and vibration can be learned. One practice experiment can learn knowledge of multiple subjects, and the applicability is high.
