Abstract

The invention relates to a mechanical and electrical integrated photovoltaic direct-current high-power submersible pump which comprises a submersible pump, a direct-current motor, a solar power supply component and a controller, wherein an upper end of a shell of the direct-current motor is fixedly connected with a lower end of a pump body; the upper end of a rotor shaft of the direct-current motor is connected with the lower end of a pump shaft through a coupler; the controller and the output end of the solar power supply component are connected with an input cable of the direct-current motor; and the controller is connected with a water level sensor. The controller is utilized to realize the automatic over-current protection for the direct-current motor, the maximum power tracking for the solar power supply component, the rotating speed abnormal protection for the motor, the dry striking protection for the water pump, the double-water-level detection and automatic stopping and the prevention for the backwater restarting of the pipeline. The motor has a permanent magnetic brushless position-sensor-free structure; after a stator and a rotor are respectively subjected to plastic package, the water flow is utilized to realize cooling; a graphite bearing is used for realizing water lubrication, so that the heating problem is solved; and the mechanical and electrical integrated photovoltaic direct-current high-power submersible pump has the advantages of high power of the motor, no noise, full automation, high reliability, excellent suitability of supplied water volume for evaporation capacity, high flow, high lift and all-weather unattended running.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to fluid machinery, in particular to a DC submersible pump, in particular to a mechatronic photovoltaic DC high-power submersible pump. Background technique: [0002] In agricultural and animal husbandry production, it is often necessary to use submersible pumps to extract water. The water pump is driven by a motor, so it needs to have a power source. But, often do not have power source condition in the field, therefore adopt internal combustion engine to directly drive water pump in the prior art, or drive generator to generate electricity by internal combustion engine. The fuel capacity in the internal combustion engine is limited, it cannot maintain long-term operation, the work is noisy, the exhaust gas pollutes the environment, and personnel are required to be on duty. Although solar cells can be used to generate electricity in the wild, the output of solar cells is direct current. ...
