Abstract

A reversible submerged motor includes a double open end housing with an inside bracket, a barrel-like axle holder, which is affixed to the bracket of the housing and holds a winding around a tubular axle thereof, and a vane holder, which has a shaft pivotally supported in the tubular axle of the barrel-like holder, magnets equiangularly arranged outside the barrel-like axle holder corresponding to the winding, and a vane disposed outside the housing for moving water, two slotted semispherical caps respectively fastened to the two distal ends of the housing, two guards respectively fastened to the two ends of the housing around the semispherical caps for controlling water flowing angle, and a controller with a timer for controlling forward/backward alternative rotation time of the vane holder.

Claims

1. A reversible submerged motor comprising:

a hollow cylindrical, double open end housing, said housing having a bracket fixedly provided on the inside and a plurality of mounting holes spaced around the periphery of each of two distal ends thereof;

a barrel-like axle holder fixedly mounted inside said housing, said barrel-like axle holder having an axially extending tubular axle and a winding fixedly mounted on the inside around said tubular axle;

a vane holder capped on one end of said barrel-like axle holder, said vane holder having a shaft rotatably supported in said tubular axle of said barrel-like axle holder, a plurality of magnets equiangularly provided at a first side thereof outside said barrel-like axle holder and adapted to act with said winding for causing said vane holder to rotate relative to said barrel-like axle holder, and a vane fixedly provided at a second side thereof and disposed outside said barrel-like axle holder;

two semispherical caps respectively fastened to the two distal ends of said housing, said semispherical caps each having a plurality of longitudinal slots and a plurality of raised positioning portions respectively engaged into the mounting holes of said housing;

two guards respectively coupled and rotatable relative to said semispherical caps, said guards each having a coupling ring portion respectively coupled to said semispherical caps and a semispherical shade extending from one side of said coupling ring;

a transformer electrically connected to said winding and adapted to convert AC power supply into DC power supply for the working of said winding; and

a controller electrically connected to said transformer and said winding for controlling supply of electric current from said transformer to said winding.

2. The reversible submerged motor as claimed in claim 1, further comprising two water guide cones respectively fixedly fastened to two distal ends of said center shaft of said vane holder.

3. The reversible submerged motor as claimed in claim 1, further comprising two fan blade assemblies respectively affixed to two distal ends of said center shaft of said vane holder.

4. The reversible submerged motor as claimed in claim 1, wherein said housing further comprises a second bracket fixedly provided on the inside, a second barrel-like axle holder fastened to said second bracket, and a second vane holder rotatably capped on said second-barrel-like axle holder.

5. The reversible submerged motor as claimed in claim 1, wherein said controller has a control knob for regulating the volume of water passing through said housing.
