A pond hydrodynamic formation equipment

Abstract

The invention discloses a pond water power forming device and method. The pond water power forming device comprises a floating body which is of a diving type structure and is adjustable in buoyancy, a speed reduction box, a motor, surge blades and a water lifting impeller. A water lifting rotating shaft and a surge rotating shaft are arranged at the output end of the speed reduction box and rotate in a differential mode, the rotating speed of the water lifting rotating shaft is higher than that of the surge rotating shaft, the water lifting impeller is connected with the water lifting rotating shaft, the surge blades are connected with the surge rotating shaft through a connecting frame, and the surge blades and the connecting frame are rotationally connected. The pond water power forming device is compact in structure and easy to operate, integrates the water power and oxygenation functions, and is capable of being automatically started and stopped and saving energy to the maximum in the oxygenation process under the three conditions of the most suitable oxygen concentration, the maximum water oxygen dissolving capability and an alerting oxygen dissolving concentration of pond culture, good in oxygenation effect and capable of ensuring uniformity of the water oxygen concentration of all parts, pond water composite and low-energy consumption water power formation and oxygenation are achieved, and the motor and the normal life of fishes are well protected.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a pond hydrodynamic forming equipment. Background technique [0002] In aquaculture, an aerator is usually used to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pool water from threatening the living environment of the fish. Aerators are generally divided into waterwheel type, impeller type, surge type, jet type and water spray type. At present, the commonly used aerators mainly include waterwheel type, impeller type and surge type. [0003] However, the traditional aerator not only has a single method of increasing oxygen, but can only increase oxygen in a certain layer of the water body, and cannot ensure that the oxygen concentration of each layer in the water body is uniform. The range of use is limited by the...

Problems solved by technology

In terms of control, the control of the traditional aerator is mostly based on the weather and the experience of the operator to artificially start and stop the aerator. The operation is cumbersome, and it is impossible to accurately judge and control the oxygen content in the water body, which is harmful to the normal survival of fish. pose a certain threat

[0005] Some remote-controlled aerators currently on the market can control the start and stop of the aerator by measuring the dissolved oxygen concentration at a certain point in the water body. Oxygen will diffuse to low solubility, and the dissolved oxygen in the water is in the process of dynamic change. Using this single control method cannot accurately and effectively judge the switch according to the content of dissolved oxygen in the water, which will lead to Frequent switching on and off of the aerator not only consumes a lot of energy, but also causes certain damage to the equipment

Moreover, the dissolved oxygen conditions of each part of the water body in the aquaculture pond are also different, and the oxygen concentration of each part is also different. The oxygen-dissolving capacity of the upper surface water body is better, the oxygen-dissolving capacity of the middle part is average, and the lower part is the worst. The method cannot guarantee the uniform oxygenation of each part of the water body

At the same time, the temperature of the water body directly affects the ability of the water body to dissolve oxygen. At a certain temperature, the ability of the water body to dissolve oxygen is limited. Continuing to turn on the machine when the oxygen concentration is high will cause waste of energy consumption

Moreover, the oxygen concentration of the water body has a limit value at different temperatures. When this value is reached, it will be ineffective to continue to increase oxygen, and it will even cause the upper water body to be rich in oxygen and cause the fish to suffer from "air bubble disease".
