Multi-power water supply and drainage device

Abstract

The invention discloses a multi-power water supply and drainage device which comprises an alternating current motor and is further provided with one or more selected from a group consisting of a direct current motor, a gasoline engine or a diesel engine, wherein a power source is provided for the alternating current motor by an alternating current power supply. A power source is provided for the direct current motor by a direct current power supply. The alternating current motor, the direct current motor, the gasoline engine and the diesel engine are connected in a coaxial or parallel mode. The multiple power sources are added on the basis of an original single power source. For example, the direct current power supply drives the direct current motor, a diesel power supply drives the diesel engine, a gasoline power supply drives the gasoline engine, and it is guaranteed that a standby power supply is automatically started to the largest extent on the basis that the original single power supply (alternating current power supply) is subjected to outage in case of emergencies so as to guarantee that the water supply and drainage device runs normally.

Description

technical field [0001] The invention relates to a water supply and drainage motor device, more specifically, relates to a multi-power water supply and drainage device. Background technique [0002] Nowadays, the water supply and drainage equipment used for construction, fire protection and domestic water supply and drainage, and water supply and drainage of municipal public facilities usually only have a single power source (usually an AC power source drives an AC motor), so when a single power source encounters an emergency and cannot During normal operation, there is no other alternative for normal water supply and drainage, and normal water supply cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a multi-power water supply and drainage device, which adds multiple power sources on the basis of the original single power source, such as: DC power source drives DC motor,...
