Abstract
The present invention is intended to provide a kind of diversion effect is good, reduce water flow diverging and can improve the pressurization water conservancy diversion spout for marine propeller of propeller efficiency.The present invention includes tubular body (1), several rectification leaves (2) are provided on the inside of the tubular body (1), several rectifications leaf (2) are uniformly distributed along the circumferencial direction of the tubular body (1), the rectification leaf (2) includes hinge part (21) and straight leaf portion (22), angle between the hinge part (21) and the straight leaf portion (22) is obtuse angle, the internal diameter of the tubular body (1) gradually becomes smaller from one end to the other end, the biggish one end of internal diameter of the hinge part (21) close to the tubular body (1).The present invention is applied to the technical field of propeller spout.
Description
Technical field
The present invention is applied to the technical field of propeller, in particular to a kind of pressurization water conservancy diversion for marine propeller sprays
Mouthful.
Background technique
Currently, traditional underwater propeller has hydraulic propeller and propeller to promote.Screw propeller be by propeller hub and
Propeller composed by several blades being radially fixed on hub, the practical water flow area loss for generating power is more, function
Consume is lost more.Hydraulic propeller is the propeller that thrust is generated using the water reaction of ejection, but its sprayed water flow is spiral shell
Outer divergence form water flow is revolved, also has and spout progress water conservancy diversion is installed at hydraulic propeller, but the water flow of tip of propeller blade is still at diverging
The water flow of type, active force is not concentrated, the low efficiency that propeller generates.Meanwhile the common fixed inner stator of spout central is to water flow
There is resistance, the guidance of tip of propeller blade water flow is played a role small.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide, a kind of diversion effect is good, subtracts
Few water flow diverging and the pressurization water conservancy diversion spout for marine propeller that propeller efficiency can be improved.
The technical scheme adopted by the invention is that: the pressurization water conservancy diversion spout includes tubular body, in the tubular body
Side is provided with several rectification leaves, and several rectification leaves are uniformly distributed along the circumferencial direction of the tubular body, the rectification leaf
Including hinge part and straight leaf portion, the angle between the hinge part and the straight leaf portion is obtuse angle, the internal diameter of the tubular body
It is gradually become smaller from one end to the other end, the hinge part is close to biggish one end of internal diameter of the tubular body.
By above scheme as it can be seen that by using rectification leaf as guide frame, and by several rectification leaf circumference array
The inside of the tubular body is set, interfere with each other several rectification leaves will not during the work time, and then prevent from producing
Raw blocked space influences the jet velocity of water flow.Water flow is received during through the tubular body by horn-like design
Beam concentrates whole thrust more, improves the efficiency of propeller.When water flow passes through the rectification leaf, in the hinge part and described
Direct-injection is changed into from helical form injection under the action of straight leaf portion, and then the diverging for reducing water flow concentrates thrust more, improves and promote
The thrust of device makes the change flow direction that water flow is relatively mild, in turn wherein playing the guiding function of water flow by the way that the hinge part is arranged
It avoids water flow from directly colliding with the straight leaf portion and generates biggish resistance, and then reduce the loss of propeller power.
One preferred embodiment is that the rectification leaf is streamlined structure.
By above scheme as it can be seen that the rectification leaf by using airflow design reduces the generation being vortexed, Waterflow-guiding is improved
Ability and the generation for reducing resistance to water-flow, and then improve propeller working efficiency.
One preferred embodiment is that the angle between the hinge part and the straight leaf portion is 22 °.
By above scheme as it can be seen that the angle can maximize the resistance for reducing and generating to water flow, can more effectively improve
Propeller working efficiency.
One preferred embodiment is that the height of the rectification leaf is 0.15-0.35 times of the maximum inner diameter of the tubular body.
By above scheme as it can be seen that the height of the rectification leaf is 0.15-0.35 times of the maximum inner diameter of the tubular body
When, it can be ensured that the spiral water flow at the tubular body center is in collect shape.
One preferred embodiment is to set altogether on the tubular body there are four the rectification leaf.
Have above scheme as it can be seen that four it is described rectification leaves can satisfy guidance water flow effect, while the rectification leaf it
Between there are enough gaps to ensure that water flow has enough passage spaces.

Specific embodiment
As shown in Figure 1 to Figure 3, in the present embodiment, the pressurization water conservancy diversion spout includes tubular body 1, the tubulose master
Several rectification leaves 2 are provided on the inside of body 1, several rectification leaves 2 are uniformly distributed along the circumferencial direction of the tubular body 1, institute
Stating rectification leaf 2 includes hinge part 21 and straight leaf portion 22, and the angle between the hinge part 21 and the straight leaf portion 22 is obtuse angle, institute
The internal diameter for stating tubular body 1 gradually becomes smaller from one end to the other end, internal diameter of the hinge part 21 close to the tubular body 1
Biggish one end.
In the present embodiment, the rectification leaf 2 is streamlined structure.
In the present embodiment, the angle between the hinge part 21 and the straight leaf portion 22 is 22 °.
In the present embodiment, the height of the rectification leaf 2 is 0.15-0.35 times of the maximum inner diameter of the tubular body 1.
The rectification leaf 2 there are four being set altogether on the tubular body 1.
The working principle of the invention:
As shown in figure 3, water flow changes flow direction under the action of rectification leaf 2 when passing through the pressurization water conservancy diversion spout, and
It is collected under the inner wall guiding role of the tubular body 1, and then sprays the pressurization water conservancy diversion spout in a manner of direct-injection.
