Multiple-supply flow pushing device capable of increasing water body dissolved oxygen proportionality

Abstract

The invention discloses a multiple-supply flow pushing device capable of increasing the water body dissolved oxygen proportionality. The multiple-supply flow pushing device comprises at least one flow pushing water pump used for pushing the water body to flow, a support device used for supporting the flow pushing water pump and adjusting the position of the flow pushing water pump, a photovoltaic array, a storage battery and a master controller. The master controller comprises a DSP master control chip, a detection circuit, two drive circuits and a power supply switching circuit. The DSP master control chip is used for controlling charge and discharge of the storage battery and the operating state of the flow pushing water pump. The detection circuit carries out voltage and current detection, and is used for detecting the power generation condition of the photovoltaic array. The drive circuits controls the charge and discharge by means of the on-off frequency control of a high frequency switch. The power supply switching circuit achieves control of charge and discharge. By employing the flow pushing water pump, the distribution proportionality of dissolved oxygen in the water body can be effectively improved, relative to the condition before the flow pushing process, the dissolved oxygen concentration is increased by 1-2mg / L, photoelectric conversion of the photovoltaic array is employed, energy is stored in the storage battery, the multiple-supply flow pushing device is energy-saving and environmentally friendly, and continuous and stable power can be ensured.

Description

technical field [0001] The invention relates to a flow pushing device for increasing the balance of dissolved oxygen in water body with multi-channel power supply. Background technique [0002] In aquaculture, conventional aeration equipment mostly uses conventional electricity, which consumes a lot of power, and most of them are aimed at oxygenation of local waters. In aquaculture, due to the difference in environmental factors, the distribution of dissolved oxygen concentration has a large difference. The aerobic characteristics of fish lead them to gather in areas with high dissolved oxygen concentration, which limits the amount of aquaculture per unit area. At present, the commonly used aeration device focuses on increasing the concentration of dissolved oxygen, but there is still a blank in the device for improving the balance of dissolved oxygen, so it is necessary to improve it. Contents of the invention [0003] The purpose of the present invention is to address t...

[0002] In aquaculture, conventional aeration equipment mostly uses conventional electricity, which consumes a lot of power, and most of them are aimed at oxygenation of local waters

In aquaculture, due to differences in environmental factors, the distribution of dissolved oxygen concentration is quite different. The aerobic characteristics of fish lead them to gather in areas with high dissolved oxygen concentration, which limits the amount of aquaculture per unit area.

At present, the commonly used aeration device focuses on increasing the concentration of dissolved oxygen, but there is still a blank for the device to improve the balance of dissolved oxygen, so it is necessary to improve it
