An oxygen-enhancing device based on Stirling engine

Abstract

The invention discloses an aeration device based on a Stirling engine. The aeration device comprises a floating body, a mounting cavity is formed in the middle of the floating body, a power air cylinder is arranged in the mounting cavity, and the outer side of the power air cylinder is fixedly connected with the floating body through a connecting rod; supporting plates are symmetrically arranged at the two sides of the upper end of the floating body, a crankshaft is horizontally arranged between the left and right supporting plates, the left supporting plate is provided with a first bearing base matched with the crankshaft, the right supporting plate is provided with a second bearing base matched with the crankshaft, and the two ends of the crankshaft are connected with an auger water lifting mechanism; the power air cylinder is internally provided with a replacement piston, a gap is formed between the replacement piston and the inner wall of the power air cylinder, the upper right endof the replacement piston is vertically provided with a driving piston rod, and the upper end of the driving piston rod penetrates through a sliding sleeve located at the upper right side of the power air cylinder. The aeration device is simple and reasonable in structure, a Stirling engine principle is adopted for providing aeration power, and the aeration device achieves the functions of aeration and energy saving.

Description

technical field [0001] The invention relates to the technical field of new energy equipment, in particular to an oxygen increasing device based on a Stirling engine. Background technique [0002] At present, the aerators used in aquaculture mainly include impeller type, waterwheel type, jet type and microporous aeration type. The purpose is to increase the density and production of pond culture by improving the dissolved oxygen in pond water. . However, a common problem of these models is that each aerator has a limited area of ​​action and can only benefit the water surface that can be splashed by the water splash. Therefore, in a pond with a slightly larger area, it is usually necessary to arrange multiple aerators separately. lead to an increase in farming costs. [0003] The Stirling engine outputs power through a cycle of cooling, compression, heat absorption, and expansion of the working medium (hydrogen or helium) in the cylinder, so it is also called a heat engine....
