Abstract
The utility model discloses a single-blade screw propeller and an amphibious ship using the same. The single-blade screw propeller can generate thrust in water, and simultaneously can travel in mud. The amphibious ship using the single-blade screw propeller can not only travel in water normally, but also travel on part of the land, and is not easy to run aground. Because the propeller is not provided with a radial impeller, the possibility that the propeller is wound by fishing nets and the like can be reduced; and in addition, the damage to fish can be reduced by the single-blade screw propeller.
Description
Technical field
The utility model relates to a kind of water surface transit equipment, particularly a kind of amphibious vessel and screw propeller.
Background technology
Present stage, increasing to the demand of amphibious vessel along with agrotechnical development, pressing for can be at the instrument of the water surface and marsh continuous working.At present, amphibious vessel can satisfy the requirement at surface navigation, simultaneously again can be in the technology and the prematurity of the navigation in offshore banks and marsh.
For example, application number is 200720133582.6, denomination of invention discloses a kind of dual-purpose ship in water route of lotus root-digging out operation for the Chinese utility model patent of " a kind of multifunctional amphibious workboat ", and its screw propeller by 4 the wheel formulas in hull both sides is advanced in shallow water or marsh.This amphibious vessel can only be advanced in shallow water, if in deep water, the screw propeller of its 4 wheel formulas in both sides all in water with not ing, the work of drying forward of its rotation generation and backward the drying work offset, hull can't move ahead; This hull construction is comparatively complicated simultaneously, and manufacture process requirement is higher.
Though other can solve the problem of advancing by the angle of rake amphibious vessel of back-pushed snail oar formula in deep water, navigate by water in the marsh again, the mode effect that adds wheel-mounted is also not fully up to expectations, is difficult to popularize come.
The utility model content
The utility model designs efficient single leaf spiral propeller that advances of a kind of water surface simultaneously and marsh and the amphibious vessel that uses this spiral propeller in order to overcome the above problems, and concrete technical scheme is as follows:
A kind of single leaf spiral propeller, comprise a rotating shaft and in the shape of a spiral shape curl up helicallobe in rotating shaft.This single leaf spiral propeller can produce powerful propulsive force when high speed revolution, contrarotation can also produce the pulling force that retreats; The brill ground principle of auger has been used for reference in the helicallobe design of its spiral, can rotate propelling in earth.
Preferably, the lead angle of described helicallobe is the 5-25 degree.
Preferably, described single leaf spiral propeller length is 0.3-1M, and diameter is 10-20CM.
A kind of amphibious vessel that adopts above-mentioned single leaf spiral propeller, comprise hull, CD-ROM drive motor, driving device, steering hardware and transmission system, described CD-ROM drive motor is connected with at least one single leaf spiral propeller by driving device, single leaf spiral propeller is arranged on hull bottom, and the helicallobe of described single leaf spiral propeller partly protrudes in the hull bottom setting.The setting that protrudes in hull bottom is wetly to advance earth in conjunction with the area rotation in order to do in the marsh etc., and the rotation that its action principle is similar to auger advances.
Single leaf spiral propeller of the present utility model can also be advanced in mire in the generation thrust in water.The amphibious vessel that uses single leaf spiral propeller not only can be in water cruising, and can travel in the part land, be not easy stranded.Because propelling unit does not have radial impeller, therefore can reduce the possibility of being twined by things such as fishnet; In addition, this list leaf spiral propeller also can reduce the infringement to fish.
Description of drawings
Fig. 1 is the apparatus structure scheme drawing of the utility model list leaf spiral propeller.
Fig. 2 is the apparatus structure scheme drawing of the utility model amphibious vessel.
Fig. 3 has installed the apparatus structure back view of two tool list leaf spiral propellers for the utility model amphibious vessel.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1: a kind of single leaf spiral propeller, comprise a rotating shaft 1 and in the shape of a spiral shape curl up helicallobe 2 in rotating shaft.This single leaf spiral propeller can produce powerful propulsive force when high speed revolution, contrarotation can also produce the pulling force that retreats; The brill ground principle of auger has been used for reference in helicallobe 2 designs of its spiral, can rotate to move ahead in earth.
The lead angle ψ of helicallobe 2 is the 5-25 degree.
Single leaf spiral propeller length L is 0.3-1M, and diameter D is 10-20CM.
As shown in Figure 2: a kind of amphibious vessel that adopts above-mentioned single leaf spiral propeller, comprise hull 3, CD-ROM drive motor, driving device, steering hardware and transmission system, CD-ROM drive motor is connected with at least one single leaf spiral propeller 4 by driving device, single leaf spiral propeller is arranged on hull 3 bottoms, and the helicallobe of single leaf spiral propeller 4 protrudes in hull 4 bottoms.The setting that protrudes in hull 4 bottoms is wetly to advance earth in conjunction with the area rotation in order to do in the marsh etc., and its action principle is similar to auger.
Transmission system wherein is used to control the speed that hull is advanced, and steering hardware is used to control the direction that hull is advanced.
As shown in Figure 3, this amphibious vessel is at hull 3 bottom branches be arranged in parallel single leaf spiral propeller 5 and single leaf spiral propeller 6, and this set helps increasing angle of rake propulsive force.
The utility model is not limited to the blade parameter setting of described single leaf spiral propeller; also be not limited to the structure of amphibious vessel, the amphibious vessel of all single leaf spiral propellers and this list leaf spiral propeller of employing all falls within the scope that the utility model is asked for protection.
