Description

The improved guard shield that is used for hydro thrust device
Background of invention
Technical field
The present invention relates to marine propulsion (marine propulsion device), such as pulling motor (trolling motor), outboard motor, stern drive etc., more specifically, relate to safety and the hydro-flow thrust (hydro-flow thrust) of improving hydraulic transmission (hydro-drive device).
Background technology
Screw drives propelling unit (screwdriven propeller) and pusher (impeller) have been used to advance marine communication means (marine vehicle) more than 100 year.For many years, advance drive technology that incredible change has taken place.Yet except size and dimension, the propeller/impeller technology does not but relatively change.
When propeller/impeller was rotated, water was inhaled into and the flywheel action by propeller/impeller quickens, and had increased the current of the fair speed of (stern) after the propeller/impeller.By suck water with higher speed and release water be used for quicken water and be known as water is increased momentum.The momentum of this water (current) or the variation of acceleration/accel have produced the power that is called as " thrust ".The curve of propeller/impeller blade produces the low pressure of vacuum side of blade, thereby causes rising, the spitting image of the wing on the aircraft.For ship propeller/pusher, rising is converted to horizontal motion.
The rotating blade of propeller/impeller produces hydro-flow thrust, and this can be depending on several factors.The speed of the current that the example of this factor comprises the water yield that per time unit quickens, propeller/impeller diameter, enter, the density of water and quicken propeller/impeller shaft horsepower (SHP, shafthorsepower).The same with all motorized industry, dropped into a large amount of expenses and efficient and the power of making great efforts to improve motor.Perhaps, the factor about the maximum of efficient and power or hydro-flow thrust is a propeller/impeller.
Propeller shroud also has the additional benefits of the submerged objects of preventing contact propeller/impeller.Along with marine communication means owner's continuous increase, as if the injury or the infringement accident that cause owing to the propeller/impeller bump are also very usual, though very unfortunate.Guard shield prevents that people, aquatic sports fan and the organism in water (marine life) of swimmer, water sledge from running into or being involved in the rotating blade of propeller/impeller.Safety is to be enclosed in the propeller shroud by the whole flywheel zone with propeller/impeller to realize.
Can realize that the guard shield of protecting people, ocean and plant life to avoid the function of propeller/impeller injury is available.Yet available guard shield trends towards limiting the current that current, increase resistance or change are left.Above-mentioned active each reduced hydro-flow thrust all discernablely, thereby influenced function negatively.
From the fwd discussion, clearly, need a kind of can the protection personnel, ocean and plant life and can increase the device of the hydro-flow thrust that Steamship propeller/pusher produces.Advantageously, this system improves performance with the amount and the speed of installing the hydro-flow thrust in the eddy current (vortex) that will increase current, minimizing resistance and can leave (exit) guard shield by increase.
Summary of the invention
