Abstract
The utility model discloses a soft basic double -bladed screw propulsion ware, including the flotation pontoon body and blade, the periphery of the flotation pontoon body is equipped with the blade that two minimum pitchs increaseed and helix angle increases, it is as an organic whole that the blade adopts two blades to become the butt welding of triangle -shaped formula, flotation pontoon body symmetry is provided with two and spiral opposite direction, this soft basic double -bladed screw propulsion ware, adopt the blade of triangle -shaped formula butt welding, it increases the quantity of unit length blade again to increase helix angle, improve the holistic intensity of blade simultaneously, very big improvement the mobility of soft basic medium on the blade surface, guarantee the blade of enough quantity and the contact surface of soft basic medium, produce great useful power, the propulsion capability of device and the speed of walking have been improved, this novel use simple structure, the propulsion capability is strong, and can be popularized and used.
Description
Technical field
The utility model relates to the thrust unit of advancing of soft base work car, is specially a kind of soft base twayblade spiral propeller.
Background technology
Various soft base (beach, the marshy area etc.) spiral propeller existed in the market is single leaf design, there is many weak points in it: causes helicallobe pitch to be restricted, after adding coarse-pitch, to contact blade few with soft base, stress point very little, cause soft base contactant to move, comparatively high thrust cannot be formed, and gait of march is slower at all.
Utility model content
The purpose of this utility model is to provide a kind of soft base twayblade spiral propeller, pushes away hypodynamic problem in actual use to solve single head (single page sheet) spiral propeller.
For achieving the above object, the utility model provides following technical scheme: a kind of soft base twayblade spiral propeller, comprise floating drum body and blade, the outer blade being arranged with minimum two pitch increasing and lead angle increasing of described floating drum body, described blade adopts two blade triangularity formulas to being welding as one, and described floating drum body is symmetrically arranged with two and hand of spiral is contrary.
Preferably, described blade adopts twayblade or mutliblade version to be welded.
Preferably, described blade is welded into global sections shape is triangle or trapezoidal.
Preferably, described floating drum body is formed by stainless steel welded.
Preferably, described floating drum body is circle cylinder design, and the top of floating drum body and bottom are arc-shaped structure.
Compared with prior art, the beneficial effects of the utility model are: this soft base twayblade spiral propeller, adopt the blade of triangular form butt welding, strengthen the quantity that lead angle increases again unit length blade, the probability of deformable blade inefficacy generation is reduced in the intensity improving blade integral, while extending blade service life, improve the flowing power of soft base medium at blade surface greatly, and then reducing friction resistance, ensure the blade of sufficient amount and the contact surface of soft base medium, add antagonistic force, produce larger useful power, improve the propulsion capability of device and the speed of walking, and then improve soft base device for treating sludge at beach, marshy area, efficiency of advancing in pool, this novel use simple structure, propulsion capability is strong, can promote the use of.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model blade butt welding structure schematic diagram.
In figure: 1 floating drum body, 2 blades.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of soft base twayblade spiral propeller, comprise floating drum body 1 and blade 2, the outer blade 2 being arranged with minimum two pitch increasing and lead angle increasing of floating drum body 1, blade 2 adopts two blade 2 triangularity formulas to being welding as one, blade 2 adopts twayblade or mutliblade version to be welded, rule of thumb formula, spiral propeller thrust and blade 2 pitch direct proportionality, by being optimized design to conventional helical propelling unit, comparison of design is carried out to construction parameter, blade 2 adopts the triangular structure form of twayblade butt welding one, improve the intensity of blade 2 entirety, reduce the probability that blade 2 deformation failure occurs, thus extend blade 2 service life, strengthen the quantity that lead angle increases again unit length blade 2 simultaneously, improve the flowing power of soft base medium on blade 2 surface greatly, and then reducing friction resistance, ensure the blade 2 of sufficient amount and the contact surface of soft base medium, make actual thrust closer to theory calculate, add antagonistic force, produce larger useful power, improve angle of rake tractive force and gait of march, by strengthening lead angle, add the contact surface of floating drum body 1 and soft substrate matter, improve propelling unit tractive force and gait of march, thus improve the propulsion capability of device and the speed of walking, and then improve soft base device for treating sludge at beach, marshy area, efficiency of advancing in pool, it is triangle or trapezoidal or rectangle that blade 2 is welded into global sections shape, floating drum body 1 is symmetrically arranged with two and hand of spiral is contrary, floating drum body 1 passes through corrosion stability, the stainless steel welded of good salt tolerance forms, and the surface of floating drum body 1 is rough surface, floating drum body 1 is circle cylinder design, and the top of floating drum body 1 and bottom are arc-shaped structure, carrying out smoothly of forward operation is convenient in the use of floating drum body 1.
Be used on soft base device for treating sludge during use, the floating drum body 1 that the rotary orientation be arranged symmetrically with by two is contrary, utilize and advance the drive that driving source is HM Hydraulic Motor, spiral propeller driven forward under the cooperation of blade 2, thus soft base device for treating sludge is walked in beach, marshy area, pool.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
