Abstract

A bi-directional reversible submersible motor, which includes a housing having an inside bracket, two water guide plates fastened to the two distal ends of the housing and covered with a respective cap, a locating rod connected between the water guide plates, a sleeve affixed to the bracket and holding a winding, a magnetic shaft and fan blade assembly rotatably supported on the locating rod in the sleeve for rotating two fan blades to pump water when the winding is electrically energized, and a controller for controlling the supply of electric current to the winding to control the direction and time of rotation of the fan blades.

Claims

1. A bi-directional reversible submersible motor comprising:

a housing, said housing having at least one bracket fixedly mounted on an inside thereof and two opposite open ends;

a sleeve affixed to said at least one bracket inside said housing, said sleeve holding a winding around an inside wall thereof;

two water guide plates respectively fastened to the two opposite open ends of said housing, said water guide plates each having a center through hole;

a shaft and fan blade assembly rotatably suspending in said sleeve, said shaft and fan blade assembly comprising a tubular shaft inserted through said sleeve, a magnet affixed to and extending around a periphery of said tubular shaft and suspending in said sleeve, and two fan blades respectively fastened to two distal ends of said tubular shaft;

two caps respectively fastened to the two opposite open ends of said housing and respectively covered on said water guide plates;

two semispherical grilles respectively fastened to the two opposite open ends of said housing and surrounding said caps, said semispherical grilles each having a plurality of radial slots and a coupling groove around the periphery of one end thereof; and

two guards, said guards each having a circular coupling portion respectively pivotally coupled to the coupling grooves of said semispherical grilles and a semispherical guard shell extended from said circular coupling portion.

2. The bi-directional reversible submersible motor as claimed in claim 1, further comprising a locating rod inserted through said tubular shaft and a center through hole of each of said fan blades and fixedly connected between the center through holes of said water guide plates to support rotation of said shaft and fan blade assemblies.

3. The bi-directional reversible submersible motor as claimed in claim 1, wherein said housing comprises two brackets;

said shaft and fan blade assembly is comprised of two symmetrical halves respectively supported in said brackets of said housing.

4. The bi-directional reversible submersible motor as claimed in claim 1, wherein said housing has a plurality of water inlets around the periphery of each of the two opposite open ends thereof.

5. The bi-directional reversible submersible motor as claimed in claim 1, wherein said housing has said winding arranged around an inside wall thereof adapted to act with the magnet of said shaft and fan blade assembly.

6. The bi-directional reversible submersible motor as claimed in claim 1, wherein said housing has mounting members arranged around the periphery of each of the two opposite open ends thereof for securing said caps.
