Abstract
The utility model discloses a double-spiral thruster which comprises a transmission shaft, a first blade and a second blade, wherein the structure of the first blade and the structure of the second blade are the same. A folded shape of the first blade is in a partial circular ring shape. The edge of one end of the partial circular ring shape is composed of a straight line and an involute. One end of the straight line is connected with one end of an inner arc of the partial circular ring shape. The other end of the straight line is connected with one end of the involute. The other end of the involute is connected with one end of an outer arc of the partial circular ring shape. One end of an inner arc of the first blade is located at one end of the surface of the transmission shaft. The other end of the inner arc of the first blade is located at the other end of the surface of the transmission shaft. The inner arc of the first blade is arranged on the surface of the transmission shaft, and the first blade is in a spiral shape. The second blade is arranged on the transmission shaft and is symmetrical with the first blade. According to the double-spiral thruster, waterweeds can be removed, and normal operation is ensured.
Description
Technical field
The utility model relates to a kind of propelling unit, particularly a kind of double helix propelling unit.
Background technology
Existing a kind of amphibious vehicle, it comprises propelling unit.Angle of rake main effect is to realize amphibious vehicle normally travelling in water.Existing propelling unit contains transmission shaft, at least two blades, and blade is uniform to be arranged on the side face of transmission shaft.Uniform blade and the junction of transmission shaft on side face that is arranged on the transmission shaft side face, only be connected with a section of transmission shaft surface, and not with the transmission shaft two ends between the surface all be connected, simultaneously since a plurality of blades axially discontinuous, therefore when in the shallow water position more pasture and water being arranged easily strand upload moving axis and blade, make it can't normal operation.
The utility model content
The technical problems to be solved in the utility model provides a kind of double helix propelling unit, can remove pasture and water, guarantees normal operation.
For solving the problems of the technologies described above, a kind of double helix propelling unit of the utility model, contain transmission shaft, blade one and blade two, blade one is identical with the structure of blade two, the expansion shape of described blade one is the part annular arrangement, the edge of one end of this part annular arrangement is made of straight line and involute, one end of this straight line links to each other with an end of the interior circular arc of part annular arrangement, the other end of this straight line links to each other with an end of involute, the other end of involute links to each other with an end of the external arc of part annular arrangement, one end of described blade one interior circular arc is positioned on the end on described transmission shaft surface, the other end of described blade one interior circular arc is positioned on the other end on described transmission shaft surface, and the interior circular arc of described blade one is arranged on the described transmission shaft surface and one one-tenth helical structure of blade; Described blade two be arranged on the described transmission shaft surface and with described blade one symmetry.
In above-mentioned double helix propelling unit, because the two-end-point of the interior circular arc of blade one and blade two all is positioned on the two ends on described transmission shaft surface, thereby the surface between blade one and blade two and the transmission shaft two ends all is connected, so can not twists on transmission shaft when running into more pasture and water; Simultaneously because blade one and blade two are continuous helical structure, and the edge that is positioned at an anterior end is made of straight line and involute, when therefore running into more pasture and water, by angle of rake rotation, pasture and water are forced to be sent to angle of rake end and are discharged from, thereby clear out of propelling unit fully, guarantee angle of rake normal operation.Owing to adopt twayblade, so propulsion coefficient is high.

The specific embodiment
Among Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of double helix propelling unit contains transmission shaft 1, blade 1 and blade 23.Blade 1 is identical with the structure of blade 23.As shown in Figure 5, the expansion shape of described blade 1 is the part annular arrangement, and the edge of an end of this part annular arrangement is made of straight line CD and involute DE.The edge of the other end of this part annular arrangement is made of straight line AB.The end of this straight line CD links to each other with an end C of the interior circular arc of part annular arrangement, and the other end of this straight line CD links to each other with the end of involute DE, and the other end of involute DE links to each other with an end E of the external arc of part annular arrangement.As shown in Figures 2 and 3, one end C of described blade one 2 interior circular arcs is positioned on the end on described transmission shaft 1 surface, the other end B of described blade one 2 interior circular arcs is positioned on the other end on described transmission shaft 1 surface, and the interior circular arc of described blade 1 is arranged on described transmission shaft 1 surface upward and blade one 2 one-tenth helical structures.Described blade 23 be arranged on described transmission shaft 1 surface upper and with described blade one 1 symmetries.In above-mentioned double helix propelling unit, because the two-end-point of the interior circular arc of blade 1 and blade 23 all is positioned on the two ends on described transmission shaft 1 surface, thereby the surface between blade 1 and blade 23 and transmission shaft 1 two ends all is connected, so can twist on transmission shaft 1 when running into more pasture and water; Simultaneously because blade 1 and blade 23 are continuous helical structure, and the edge that is positioned at an anterior end is made of straight line and involute, when therefore running into more pasture and water, by angle of rake rotation, pasture and water are forced to be sent to angle of rake end and are discharged from, thereby clear out of propelling unit fully, guarantee angle of rake normal operation.Owing to adopting twayblade, i.e. blade 1 and blade 23, so propulsion coefficient is high.
