Description
Technical field
The present invention relates to model ship manufacture technology field.
Background technology
Model plane are abbreviations of model ship, refer to the model of boats and ships, warship, also refer to modelling, match, exhibition, performance in sports item.It is a science and technology, military affairs, physical culture, culture and education activity.By various ways such as analogue formation, match, exhibition, performance, understand the various knowledge about boats and ships, naval, aspect, ocean, improve teen-age overall qualities.Model ship match has been carried out more than 40 years in China, is subject to broad masses, particularly teen-agely likes.
Most of model ships are to be provided by electro-motor.Electro-motor is connecting a propeller shaft that enters water conventionally, at the water intake end of propeller shaft, screw is installed.Rely on the rotation of electro-motor drive screw, for model plane provide the power advancing.
At present, model ship makes hull made of plastic substantially, has a through hole at hull afterbody, and propeller shaft can be inserted below the water surface through this through hole.The people who made model plane knows, exists just the through hole that this is opened for propeller shaft, the situation that can leak after water under model plane.
Also there is the blasthole of propeller shaft in large ship, it is following several that it prevents that the method for leaking from having: 1, adopt complicated diaphragm structure, form loop, and mate gear transmission, make the water outside boats and ships cannot enter cabin.But the design of this complexity is not obviously suitable for small ship model.2, use water-sealed bearing, reach the effect blocking water.But there is no at present diameter at grade and cheap water-sealed bearing, the cost that model plane are made does not allow special this trickle precision part yet.To sum up, the seepy question of model plane can not find enlightenment from real boats and ships.
The common solution of most of airplane hobbyists has following several: 1, the aperture of propeller shaft blasthole approaches with the diameter of propeller shaft as far as possible, forms little matched in clearance.But this way can make the two existence necessarily rub.Repeatedly the rub hole wall of plastics of the propeller shaft of metal, can make little gap expand gradually, still can leak.2, adopt the blasthole of the shutoff propeller shafts such as machine oil, butter, vaseline.The method is most airplane hobbyists' way, and still, when after water under model plane, some can drain to machine oil, butter or vaseline in water, forms bright oil film at the water surface, also needs timing to supplement plug.The method has certain technique effect, in professional model ship match, gives no cause for much criticism.But, if classmates, in Miniature pool, fish jar, while even using model plane in swimming pool the inside, will cause that other people is unhappy.3, adopt rubber peel shutoff.First on a rubber peel, cut the circular hole that a diameter is less than propeller shaft, rubber peel is attached to around the blasthole on hull, circular hole is aimed at blasthole.Allow propeller shaft first through the hole cutting on rubber peel, again through the blasthole on hull.Rely on like this sealing function of rubber peel, reach the effect blocking water, but this method makes between propeller shaft and rubber peel, to have larger frictional force, hinder the power output of the original just very little electro-motor of power, not only make being short of power of model, long-term use also can damage electro-motor, and after ageing of rubber, effect can be not good yet.
Summary of the invention
The object of this invention is to provide a kind of not affecting model plane power, do not affect under the prerequisite of the water body around model plane, solve the technical scheme of ship model seepy question.
Such for realizing the technical scheme that the object of the invention adopts, a kind of model plane method that blocks water, it is characterized in that: comprise that one by model plane hull, propeller shaft, and be arranged on the model plane Water blocking system of first longitudinal floor, second longitudinal floor and the horizontal ribbed composition of model plane hull interior.
The stern of described model plane hull has screw blasthole.One end of described propeller shaft connects power, the other end through after described screw blasthole, then screw is installed.
Described first longitudinal floor and second longitudinal floor are parallel to each other, and are positioned at the both sides of propeller shaft.The lower end of first longitudinal floor and second longitudinal floor is connected to the bottom of model plane hull.The upper surface of first longitudinal floor and second longitudinal floor is higher than screw blasthole.The described horizontal ribbed below that is positioned at propeller shaft.Horizontal ribbed perpendicular to described first longitudinal floor.A described horizontal ribbed plate face is connected with first longitudinal floor and second longitudinal floor.
Comprise the following steps:
1) paraffin is melted in crucible.
2) in described crucible, add powdered graphite, stir the mixture of the paraffin composition of powdered graphite and thawing.
3) motor of startup model plane, makes propeller shaft rotation.
4) by step 2) mixture that obtains pours into first longitudinal floor, the second longitudinal floor and horizontal ribbed region enclosing.
5), after described mixture solidifies, close described motor.
Further, step 2) in, also in described crucible, add barite powder.
Further, step 3) start before, first propeller shaft is unloaded to taking-up, with paraffin shutoff screw blasthole.Again one end of propeller shaft is reconnected to power, the other end through the paraffin of shutoff in screw blasthole.
Further, step 4) in, the detailed process that pours into described mixture is, described crucible is placed in to the top of the propeller shaft rotating, the mixture of thawing is dropped on the propeller shaft rotating gradually, until the mixture melting fills up first longitudinal floor, the second longitudinal floor and horizontal ribbed region enclosing.
Further, step 4) in, when described crucible is placed in to the top of the propeller shaft rotating, the initial position of crucible is above screw blasthole.While the mixture of thawing being dropped in gradually on the propeller shaft rotating, described crucible axially moves reciprocatingly along propeller shaft.
The present invention is owing to having technique scheme, and its technique effect is mathematical.Specifically, the mixture of thawing is slow solidification in the process of propeller shaft rotation, and after mixture solidifies, propeller shaft still can rotate, and propeller shaft and the around frictional force between solid are little.Meanwhile, the water outside cabin also can not enter cabin by screw axis hole, has reached plugging effect.Be more preferably, screw blasthole adopts after mineral wax mixture shutoff, and the mineral wax mixture solidifying can not dissolve in water body around, after a shutoff, do not need to change, be not only applicable to the own composition model of boats and ships fan, be more suitable for factory's batch production finished product ship model.Be more preferably, adopt the ship model of the technical program can not pollute water body around, can in the water body such as swimming pool, fish jar, carry out the activities such as model plane competition, the combination property of model significantly improves.
