Abstract

The invention discloses a submersible pump device, which comprises a submersible pump body (1) and a water level switch (2) for controlling start and stop of the submersible pump body (1), wherein thesubmersible pump body (1) is connected with a connection rod mechanism (3); and the connection rod mechanism (3) and the water level switch (2) are fixedly connected to control the water level switch(2). Through the designed closed-loop system, the water level detection problem when the submersible pump body is at any pose can be solved, a power supply can be timely cut off, accidents can be prevented, an automatic power cutoff protection function is realized, and the system is ensured to operate stably and reliably.

Description

technical field [0001] The invention relates to the technical field of electromechanical products, in particular to a submersible pump device. Background technique [0002] In recent years, with the country's increasing support for the new energy industry, new energy battery cars have entered every household, which not only provides convenience for people's travel, but also reduces the harm to the environment. The battery used in the battery car has the advantages of being easy to use, convenient and efficient, which has also become an important factor for its wide application. For example, some electrical equipment, especially low-voltage DC motors, often use batteries as energy sources. In addition, the submersible pump powered by a low-voltage DC motor has a simple structure, is stable and durable, and has been widely used in many fields such as agricultural irrigation (especially emergency use of well water in dry weather), small-scale drainage, etc. When the battery is...
