Deep-well pump frequency converter capable of tracing maximum power of solar panel

Abstract

The invention discloses a deep-well pump frequency converter capable of tracing the maximum power of a solar panel and relates to the technical field of water intaking and draining machinery. The deep-well pump frequency converter comprises a water pump, a water tank and a water well and further comprises a solar panel and an MCU, wherein a water level switch is arranged in the water tank and communicates with the MCU; the MCU controls on-off of the water pump according to the signal of the water level switch; a photosensitive element is arranged on the solar panel; a rotator is arranged at the bottom of the solar panel and rotates according to the photosensitive element; and the MCU communicates with the photosensitive element and controls on-off of the water pump according to the signalof the photosensitive element. Compared with the prior art, the deep-well pump frequency converter can directly utilize the solar panel for power supply; if the water level switch of the water tank and the photosensitive element of the solar panel are equipped, the water pump can be started and stopped according to the signal to keep the water tank being full of water all the time, so that the deep-well pump frequency converter can be used in the open air and at home, does not need a storage battery and is wide in range of application.

Description

technical field [0001] The invention relates to the technical field of water intake and drainage machinery. Background technique [0002] With the development of the economy, the consumption of energy is increasing day by day, the non-renewable resources are getting less and less, and the utilization of renewable resources is becoming more and more important. Now the use of solar energy is gradually increasing, such as grid-connected inverters, off-grid inverters and other power equipment. However, the shortcomings of grid-connected inverters and off-grid inverters using solar energy are also obvious. Grid-connected inverters cannot be used separately from the grid, while off-grid inverters need to be equipped with batteries, and then basically install solar energy utilization devices. Then cost is high, and these all bring inconvenience to use. At the same time, most of the water pumps on the market must use brushed DC motors when they are separated from the inverter and ...

However, the shortcomings of grid-connected inverters and off-grid inverters using solar energy are also obvious. Grid-connected inverters cannot be used separately from the grid, while off-grid inverters need to be equipped with batteries, and then basically install solar energy utilization devices. Then the cost is high, which brings a lot of inconvenience to the use

At the same time, when most of the water pumps on the market are separated from the inverter and use solar panels, they must use brushed DC motors, which have been criticized for their short life and low efficiency.
