A wave-making aerator

Abstract

The invention discloses a wave-making oxygen increasing machine, and belongs to the field of aquaculture. The wave-making oxygen increasing machine comprises a floating body and a motor which is fixedly installed on the floating body and shares the same axis with the floating body, and the motor drives a vane wheel to rotate through a reducer. The wave-making oxygen increasing machine is characterized in that the top of the motor is provided with a swinging driver, the swinging driver comprises a support rod and a balance weight ball, the bottom end of the support rod is located at the top of the motor and the support rod shares the same axis with the motor, the top of the support rod supports the balance weight ball, the balance weight ball does reciprocating motion around the axis of the motor under the action of gravity to enable the motor to swing, the floating body is driven to tilt up and down, and therefore waves are made. Compared with the prior art, the wave-making oxygen increasing machine utilizes the potential energy of the balance weight ball to enable the motor to swing to drive the floating body to tilt to make similar natural waves in a pond, the total dissolved oxygen content of the pond is increased, and the energy-saving effect is achieved; the structure is simple, the manufacturing cost is low, energy consumption is not increased, the range of the dissolved oxygen function of one machine is large, and therefore the culturing cost is lowered.

Description

technical field [0001] The invention relates to aquaculture machinery, in particular to an aerator for fish ponds. 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. In response to this problem, Chinese patent 200520055671.4 discloses a swing aeration device, which includes a floating body that can float on the water surface and a power source installed on the floating body. The output end of the power source is connected w...

Problems solved by technology

In addition to driving the impeller to rotate, the gearbox of this type also needs to drive the rotating arm and counterweight to make the floating body sway, that is, the generation of waves also needs to obtain energy from the motor, so the power of the motor needs to be increased, and the energy efficiency ratio is lower. no improvement

In addition, because the length of the rotating arm is limited by the size of the waterproof cover, it cannot be made too long, so that the swing amplitude and the amplitude of the generated waves cannot reach the expected value; and due to the setting of the rotating arm and the counterweight, the motor is eccentric relative to the impeller shaft. The aerator is in an unbalanced state, resulting in unbalanced wave amplitude in the circumferential direction, that is, part of the swaying amplitude of the floating body is offset by the eccentric structure, which affects the aeration effect
