Abstract
The utility model discloses a screw propeller used for mudflat and swamp air boats, which is applied to an air boat used for implementing physical exploration in mudflats and swamplands, and is characterized in that an axial hole is arranged in the center of a cylindrical screw propeller fixing device. The two sides of the cylindrical screw propeller fixer are symmetrically fixed with paddle keels which are made of steel materials. Bolt holes are arranged around the axial hole. The paddle keels and the screw propeller fixing device are fixed together by bolts through the bolt holes. The outer surfaces of the paddle keels are coated with fiber glass reinforced plastics; and the paddle keels and the fiber glass reinforced plastics form the fiber glass reinforced plastics paddles. The screw propeller used for mudflat and swamp air boats has the effects that the wear resistance of the paddles is improved by adopting the fiber glass reinforced plastics to coat the outer wall of a steel skeleton; the strength of the screw propeller is improved without coating an aluminum cover; and the anti-impact performance thereof can be improved by 3 times through test. The shape and connection structure thereof are the same with that of the original screw propeller and the mounting and running parameters are not changed.
Description
Technical field
The utility model relates to earth seismic exploration technique field, be particularly related at beach, swampy terrain and implement the air ship that physical prospecting is used, being the screw propeller of physical prospecting air ship, is to be used for the propelling unit that beach, marsh, lake, river etc. carry out the air ship of geophysical exploration.
Background technology
At beach, when swampy terrain carries out geophysical exploration, common equipment comprises the air ship.At present, the screw propeller of air ship use is wooden screw propeller.Consult Fig. 1.The structure of wooden screw propeller mainly is made up of columned screw propeller anchor fitting 2 and wooden blade 1, is fixed with wooden blade 1 in the bilateral symmetry of columned screw propeller anchor fitting 2.At the center of columned screw propeller anchor fitting 2 axis hole 4 is arranged, axis hole 4 is the holes that are connected and fixed of wooden screw propeller and output shaft of gear-box.Bolt hole 3 is arranged around axis hole 4, and bolt can be fixed together wooden blade 1 by bolt hole 3 with screw propeller anchor fitting 2.And edge and leading section at wooden blade 1 are surrounded by aluminium skin 5.There are the following problems in use wooden screw propeller:
1, wooden blade 1 adopts the hardwood material to make, and corrosion resistance is relatively poor.
2, wooden screw propeller shock resistance is relatively poor, is subjected to foreign material such as shell, reed and the grains of sand and impacts blade 1, easily causes screw propeller to disintegrate, and personnel are damaged.
3, after the each use of wooden screw propeller, need guarantee that with the silt above the wet cloth wiping kinetic balance of wooden screw propeller is not destroyed.
The utility model content
The purpose of this utility model is: a kind of beach, marsh air marine propeller are provided, make this screw propeller resistance to corrosion good, maintaining is simple, shock resistance is strong, does not have potential safety hazard in the use.
The technical solution adopted in the utility model is: beach, marsh air marine propeller, mainly form by screw propeller anchor fitting, bolt hole, axis hole, blade keel and glass-felt plastic blade, and at the center of columned screw propeller anchor fitting axis hole is arranged.Bilateral symmetry at columned screw propeller anchor fitting is fixed with the blade keel.The blade keel adopt steel material (steel plate) to make.Around axis hole bolt hole is arranged, bolt is fixed together blade keel and screw propeller anchor fitting by bolt hole.Outside face at the blade keel is surrounded by glass-felt plastic, and blade keel and glass-felt plastic are formed the glass-felt plastic blade.
The length of described blade keel and thickness are 1/2nd of wooden blades, and the angle of inclination of blade keel is identical with wooden blade.
The length of described glass-felt plastic blade is identical with wooden blade with thickness, and the angle of inclination of glass-felt plastic blade is identical with wooden blade.
The manufacturing process of beach, marsh air marine propeller:
At first, make the blade keel, the blade keel are that steel material (steel plate) is made.The profile of blade keel is similar to wooden blade, and blade keel symmetry is fixed on the both sides of screw propeller anchor fitting.Then, screw propeller anchor fitting and blade keel together are fixed in the mould of screw propeller.The inner chamber of screw propeller mould is identical with the profile of wooden screw propeller.Adopt the method for making of glass-felt plastic at last, the glass-felt plastic blade is wrapped in the appearance of blade keel.After treating that glass-reinforced plastic material solidifies, finish the making of beach, marsh air marine propeller.
The beneficial effects of the utility model: beach, marsh air marine propeller, adopt glass-reinforced plastic material to be wrapped on the steel skeleton outer wall, improved the resistance to abrasion and the corrosion stability of blade, without the alclad skin; Improved the intensity of screw propeller, improved 3 times by testing its shock resistance.Its profile is identical with former screw propeller with connection structure, and the installation and operation parameter does not change.

The specific embodiment
Embodiment 1: with CH3-914 type beach, marsh air marine propeller is example, and the utility model is described in further detail.
Consult Fig. 2.The utility model beach, marsh air marine propeller are made up of screw propeller anchor fitting 2, bolt hole 3, axis hole 4, blade keel 6 and glass-felt plastic blade 7.
Consult Fig. 3.An axis hole 4 is arranged at the center of columned screw propeller anchor fitting 2.The diameter of axis hole 4 is 57 millimeters.Transmitting rotary power can be connected by axis hole 4 with output shaft of gear-box.Bilateral symmetry at columned screw propeller anchor fitting 2 is fixed with blade keel 6.Blade keel 6 adopt steel material (steel plate) to make.The length of blade keel 6 is 1000 millimeters, and the thickness of blade keel 6 is 19.25 millimeters.The angle of inclination of blade keel 6 is identical with wooden blade 1.Bolt hole 3 is arranged around axis hole 4, and bolt is fixed together blade keel 6 and screw propeller anchor fitting 2 by bolt hole 3.
Consult Fig. 2.Outside face at blade keel 6 is surrounded by glass-felt plastic, and blade keel 6 and glass-felt plastic are formed glass-felt plastic blade 7.The length of glass-felt plastic blade 7 is 2000 millimeters, and the thickness of glass-felt plastic blade 7 is 38.5 millimeters.The angle of inclination of glass-felt plastic blade 7 is identical with wooden blade 1.
