Description
Technical field
The utility model relates to the underwater propeller in mechanical field, specifically a kind of Novel reciprocating type propelling unit.
Background technology
In the prior art, the propelling on various naval vessels generally adopts screw propeller or reciprocal blade to promote current, and utilize antagonistic force to drive the naval vessel and advance, but in the course of the work, because screw propeller exists the problems such as loss in efficiency is large, efficient is low by the crank-driven that engine piston connecting rod drives; And because the precise structure of screw propeller causes its manufacturing process complicated, and cost is higher, and in the course of the work, can produce resistance by convection cell, the faster resistance of speed is larger, affects the lifting of naval vessel speed.Present oar blade type propelling unit must some could be worked more than the water surface, and comformability is not high.
The utility model content
For solve that the manufacturing process that propelling unit of the prior art exists is complicated, cost is high and working process in large, the problem such as comformability is not strong of resistance, the utility model provides a kind of Novel reciprocating type propelling unit.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of Novel reciprocating type propelling unit, mainly by slider-crank mechanism with push away water pond and form, and the slide block of slider-crank mechanism is connected with the shaft hole matching that pushes away the water pond center by axle, power inputs to the crank of slider-crank mechanism, and the rotation of crank is converted to the straight reciprocating motion that the slide block drive pushes away water pond; The described water pond that pushes away is disc-shaped structure, which is provided with the water stream channel of the circular hole of perforation, pushes away and also is provided with rubber pad on the water pond, and an end of water stream channel fixed and hide by rubber pad by a bolt of water stream channel limit section;
Described water stream channel is a plurality of, evenly distributes around the center that pushes away water pond, and the number of water stream channel and radius are followed following formula:
In the formula, the h representative pushes away the thickness of water pond, and r represents the center of circle of water stream channel to the distance that pushes away the water pond center, r
bRepresentative pushes away the radius of water pond, r
aRepresentative pushes away the radius of water pond central shaft hole, r
kRepresent the radius of water stream channel, n represents the number of water stream channel, and if n be not integer, then get the maximum integer less than n;
The described edge that pushes away water pond and water stream channel is provided with fillet;
The described fillet that pushes away water pond and water stream channel edge, its radius be push away water pond thickness 0.5-1 doubly, and fillet is arranged on and pushes away the edge that deviates from the rubber pad one side on water pond and the water stream channel.
In the utility model, consider equilibrium of forces problem when pushing away water pond pushes away water, water stream channel is evenly arranged around the center that pushes away water pond, push away balance and the stability of water pond when having guaranteed to push away water;
The radius of water stream channel is unsuitable too small, can increase the entity area that pushes away water pond like this, and then increases the working resistance that pushes away water pond; Equally, the radius of water stream channel is also unsuitable excessive, can reduce the strength and stiffness that pushes away water pond first after excessive, causes reduce service life, second may not obtain maximum water permeable area;
Experimental results show that, the relation character that pushes away number and the radius of water stream channel on the water pond and push away the water pond parameter closes when stating three formula, with this understanding, what same material was made pushes away water pond under the condition of proof strength and rigidity, the resistance of its working resistance during much smaller than other size and number.
In the utility model, in order further to reduce to push away the working resistance of water pond, push away all edges that water pond and water stream channel deviate from the rubber pad one side and all fall into fillet pushing away water pond, the experiment proved that, the arc radius of fillet is when pushing away 0.5-1 times of thickness of water pond, compare the fillet of other size, resistance reduces about 10%; Simultaneously, rounding also has good operability on circular hole.
Beneficial effect: the utility model compare screw propeller of the prior art, back and forth blade and web formula propelling unit have the following advantages:
1, simple in structure, working resistance is little
Cooperating of water stream channel realizes pushing away the purpose that water advances on adopting rubber pad and pushing away water pond, and be simple in structure, simultaneously, the edge adopts fillet and water stream channel and pushes away the suitable Area Ratio of water pond, not affecting in the situation that pushes away the water pond strength and stiffness, reduced working resistance, promoted and pushed away water efficient;
2, disguise and safety are good
General propelling unit is open, forms open water ripples and disturbance during work in water, be easy to be found, and the pushing away water pond and can be installed in the cylinder of this device, (being similar to pumped well) current range of disturbance is obviously dwindled good concealment; Simultaneously owing to adopt a plurality of water stream channels, even the rubber pad of a water stream channel is interfered or when destruction and cisco unity malfunction, remaining is not affected by it, safety performance is improved;
3, propulsion coefficient is high, balance is good
This push away the water device to push away the water direction fully identical with the hull working direction, produce the component of other directions when the work unlike other propelling unit, reduced the work efficiency of propelling; Simultaneously around pushing away water pond center well-distributed water stream channel also so that whole to push away water pond stressed evenly so that this equipment balance is good, advance steadily.
