Abstract
A submerged motor vane wheel rotation direction control structure includes a blade pivoted to a locating block inside of the water guide chamber of a submerged motor, a vane wheel, the vane wheel having sloping teeth radially extended from the motor shaft of the submerged motor, which push the blade outwards toward to an open position for the passing of flow of water upon clockwise rotation of the vane wheel, and is forced into engagement with the blade to hold the blade in a close position upon counter-clockwise rotation of the vane wheel, causing the submerged motor to reverse the vane wheel.
Claims8
A submerged motor vane wheel rotation direction control structure comprising:
- a locating block provided at the vane wheel in the water guide chamber of a submerged motor, said locating block comprising a coupling groove, and a hooked portion perpendicularly disposed at one side of said coupling groove;
- a blade pivoted to said coupling groove of said locating block and secured in place by a cover plate;
- and
- a plurality of sloping teeth equiangularly spaced around the inside wall of the water guide chamber of said submerged motor.
The submerged motor vane wheel rotation direction control structure as claimed in claim 2 wherein said teeth each have a smoothed arched cross section.
A submerged motor vane wheel rotation direction control structure comprising:
- a locating block provided inside the water guide chamber of a submerged motor, said locating block comprising a coupling groove, an a hooked portion perpendicularly disposed at one side of said coupling groove, and a tongue disposed at an opposite side of said coupling groove;
- a blade pivoted to said coupling groove of said locating block;
- a stopper fixedly fastened to one end of said locating block to stop said blade in said coupling groove of said locating block;
- and
- a vane wheel mounted in the water guide chamber of said submerged motor for free rotation relative to said locating block, said vane wheel having a plurality of teeth adapted for engaging said blade to control the direction of rotation of said submerged motor.
