Floating aerator for fishpond

Abstract

The invention discloses a floating aerator for a fishpond, and relates to the technical field of cultivation. The floating aerator for the fishpond comprises a waterproof cylinder, wherein a fixing ring is fixedly installed on the outer side of the lower end of the waterproof cylinder through a fixing rod; a buoyancy ball is fixedly installed at the bottom of the fixing ring through a fixing column; an aeration plate is arranged at the bottom of the waterproof cylinder; the top of the aeration plate is connected with the bottom of the fixing rod on the outer side of the waterproof cylinder; and the waterproof cylinder comprises an air inlet cover, an oxygenation pump and a flow dividing pipe. According to the floating aerator for the fishpond, a cleaning mechanism is arranged, a movable ball is movably connected to the center of the cleaning mechanism through a spring, and when aquatic plants or sundries cover the outer side of one oxygen outlet hole, the air flow velocity and the water flow velocity at the oxygen outlet hole are decreased, and the air flow velocity and the water flow velocity at the other two oxygen outlet holes are increased, so that the movable ball is pushed towards the position with the low flow velocity; and the movable ball is stressed to move back and forth in the center of the cleaning mechanism and is matched with crushing thorns to clean the aquatic plants or the sundries, so that the oxygenation efficiency of the aerator is ensured.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to a floating aerator for fish ponds. Background technique [0002] In summer, the water space of the fish pond is too small, and the density of the fish is too high, resulting in insufficient support, which is not conducive to the normal growth of the fish, and may even cause the fish to float and die. Therefore, in fish ponds for aquatic product cultivation, often need Use an aerator to add oxygen to the fish pond; while the general floating aerator pressurizes the oxygen at the upper end through the aerator, and finally introduces the oxygen into the water through the oxygen outlet hole to make it compatible with the oxygen in the fish pond. Miscible with water to achieve oxygenation effect. [0003] In the floating aerators currently on the market, the oxygen outlet holes are easily covered by floating aquatic plants or other debris, and the contact area between oxygen and wat...

AI Technical Summary

Problems solved by technology

[0003] In the floating aerators currently on the market, the oxygen outlet hole is easily covered by floating aquatic plants or other debris, and the contact area between oxygen and water is reduced, thereby reducing the working efficiency of the aerator.
