Improved swing oxygen-increasing device

Abstract

The invention discloses an improved swing oxygen-increasing device comprising a floating body, a counterweight body rotation driving mechanism is arranged on the floating body, the counterweight body rotation driving mechanism is connected with a revolving arm, a counterweight body is arranged at the back end of the revolving arm, the revolving arm and the counterweight body are arranged above the floating body, the floating body is provided with a water chute, a water inlet of the water chute is arranged at the bottom part of the floating body, a water outlet thereof is arranged at the upper part of the floating body, a water pumping impeller is arranged at the water inlet of the water chute, and the water pumping impeller is connected with an impeller rotation driving mechanism. As the improved swing oxygen-increasing device increases the water pumping impeller, the floating body swings continuously under the rotation action of the counterweight body, and the bottom part of the floating body presses water by swing, thereby leading pool water to continuously form waves which are transferred outwards, increasing the direct contact between the pool water and air and further increasing the dissolved oxygen; the water pumping impeller pumps the pool water from the water inlet of the water chute of the floating body, and the pool water is ejected outwards at the water outlet of the water chute at the upper edge of the floating body, thereby forming spray, further increasing the dissolved oxygen and realizing good oxygen-increasing effect.

Description

technical field

[0001] The invention relates to a pond aeration device, in particular to an improved swing aeration device. Background technique

[0002] In pond aquaculture, the amount of dissolved oxygen in pond water is one of the important indicators affecting the production of aquatic products. At present, the widely used aeration measures are water wheel aerators, etc. The oxygen dissolution effect of these existing aeration devices is basically It meets the requirements of dissolved oxygen. However, due to the structural characteristics of these aeration devices, they must have the disadvantages of high power and high power consumption, which leads to the inability to effectively reduce the production cost. At the same time, the oxygen dissolution effect is still not ideal. Based on the above reasons, the applicant of this patent application has developed a new type of swing aeration device through research, and filed a patent application for this technology to the St...
