Submersible pump with rechargeable battery

Abstract

The invention discloses a submersible pump with a rechargeable battery. The submersible pump comprises a top cover arranged on a pump body, and is characterized in that a charging socket is arranged on the top cover; threaded columns are arranged in a way of surrounding the charging socket in a protruding manner; the threaded columns are provided with outer threads; the rechargeable battery supplying electricity to a motor is arranged in the pump body; outer threads are arranged on an outer wall of the charging socket; a charging plug is inserted into the charging socket; the charging plug isconnected with a movable joint in a sleeving manner; inner threads are arranged on the movable joint and the movable joint is connected to the threaded columns in a threaded manner; annular flanges are arranged on an outer wall of the charging plug; the movable joint axially presses the charging plug downwards through resisting against the annular flanges; the charging plug is provided with sealing rings under the annular flanges in a sleeving manner; and each sealing ring is pressed tightly between the each annular flange and the top end surface of the each threaded column. The invention provides the submersible pump with the rechargeable battery; through screwing the movable joint into the threaded columns arranged on the top cover and extruding the sealing rings, waterproof and sealingfunctions are achieved, so that charging in water can be realized and inflow of water is avoided.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a rechargeable battery submersible pump. Background technique [0002] Existing submersible pumps are usually directly powered by electric wires, and the use of batteries for power supply is likely to cause water ingress due to poor sealing of the charging socket, affecting the normal operation of the pump. Contents of the invention [0003] The purpose of the present invention is to provide a rechargeable battery submersible pump, which can be screwed into the threaded column on the top cover through the flexible joint and squeezed the sealing ring to achieve the waterproof and sealing function; at this time, it can be charged in water without water ingress. [0004] The object of the present invention is achieved in this way: a rechargeable battery submersible pump, including a top cover arranged on the pump body, is characterized in that: the top cover is provided with a...
