Control and protection device of aeration aerating machine with wind and solar mutual-complementing power supply

Abstract

The invention provides a control and protection device, with the power supplied by the complementation of wind and light, of an aeration oxygenation machine, relates to the environment protection field and in particular to an oxygenation aeration water quality purifying device technology in the environmental engineering subject. The device is characterized by consisting of a wind driven generator, a solar panel, a rectifying device, a protection switch, an AC contactor, an inspection switch, a storage battery, an inverter, a DC monitor, a storage battery low-voltage protection contact and a storage battery overvoltage protection contact. The positive effects brought by the implementation of the invention are: the use of the complementation system of wind and light for power supply solves the problem that energy can not be supplied stably in a single power generation and supply process by either wind energy or solar energy, saves coal energy; realizes the auto starting function of aeration equipment and automatically accumulates the working time of the aeration equipment; realizes the auto protection function against insufficient battery voltage caused by excessive electricity consumption of the aeration equipment and excessive saturation of batteries caused by excessive electricity generated by wind and light and ensures the long-term safe and stable work of the equipment.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an oxygenation and aeration water purification device technology in the discipline of environmental engineering. Background technique [0002] At present, the eutrophication of lakes, rivers and other water bodies has become a very serious environmental problem faced by the whole world. As an important water quality restoration technology, artificial oxygenation and aeration technology has been successfully applied in many lakes and rivers ecological restoration and ecological improvement projects as a temporary or emergency measure. [0003] However, this technology will be fundamentally a passive treatment technology adopted after the water body is polluted. The existence and size of external pollution sources often fall short due to the existence of external pollution sources; and although its construction cost is not high, from the perspective of long-term operation, ...

AI Technical Summary

Problems solved by technology

[0005] For this reason, this study designs a wind-solar complementary aeration combination device, which utilizes the complementary effects of wind energy and solar energy to provide stable long-term uninterrupted power energy for the aeration equipment to the maximum extent, but the battery is often damaged due to overcharging during use. , or the aeration equipment is still working in the underpressure state, which will cause damage to the equipment
