Description

The water jet swimming aid that structure simplifies

Technical field

The utility model is that the people that can help that a kind of structure simplifies swims in the water, and safety also more saves physical swimming aid, belongs to a kind of Boating-used equipment.

Background technology

Current modal swimming auxiliary equipment is water wing or rescues body clothing, but they can not help user's movement rapidly in water, separately there is a kind of hand swimming aid with delta (Authorization Notice No. CN1214832C) applied for a patent, but it is very inconvenient that it operates fatiguability with hand, contour structures like its floating drum is for can water person also be not easy to grasp balance very much, and what adopt is that propeller arrangement obtains power and makes overall connection complicated structure, and have a kind of swimming teaching arrangement with foot pedal (Authorization Notice No. CN201197865), it adopts screw equally, screw exposes, if the many place of people is just easy to hurt people, if have a small amount of pasture and water that screw also may be made to be wound in water to go wrong, and its junction complicated structure, make also complicated, add manufacturing cost, impracticable as the amusement and recreation sports goods of large-scale promotion, a water jet swimming aid (application publication number CN103877700A) was designed before designer, but owing to devising commutator separately, make structure slightly aobvious complicated, regulate length relatively so not convenient, and the resistance of the design of keel to water is larger.

Summary of the invention

In order to overcome water wing, rescue the power drill/driver of the handicapped deficiency of body clothing and screw swimming aid and easily hurt sb.'s feelings and damage, and the shortcoming of self syndeton also more complicated, and the water jet swimming aid designed before regulates length relatively to bother the inferior position larger with water resistance, the utility model structure is simpler, practicality is stronger, is easier to realize.

The technical scheme that the utility model is adopted for achieving the above object is:

Its core component is vacuum seal formula paddle wheel, vacuum seal formula paddle wheel is by sealing intact shell and paddle wheel forms, casing is at the outer surface of paddle wheel, except two end axles stretches out shell, paddle wheel is wrapped up by shell completely, internal diameter and the blade external diameter of shell match, and shell has front end water inlet and rear end delivery port.If be only that a common paddle wheel submerges in water completely, even if paddle wheel rotates but also cannot paddle, because the power stress balance that water produces paddle wheel, therefore general use all only has the latter half blade to submerge in water, after but paddle wheel puts into can, water is filled with inside can, as long as water inlet and delivery port are all lived by water seal, now inside is in vacuum state, under the effect of atmospheric pressure, all the time can be full of water in this housing, if whole vacuum seal formula paddle wheel all submerges in water, that is all the more so.And now, paddle wheel in housing rotates, the water in seal casinghousing can rotate along with blade and reach the speed that blade rotates, and due to the existence of centrifugal force and inertia, can spray water, and the speed that rotary speed sprays water is sooner also faster from water outlet.As long as delivery port and water inlet are all sealed in water in theory, this housing can be full of water all the time, so when delivery port is sprayed water, water inlet also can constantly have water to flow into, supplement the water flowed out from delivery port, now this vacuum seal formula paddle wheel is as being both a water pump.

Keel are main bodys of the present utility model, and for conductance, it is overall in Z-shaped, keel front portion is an expansion link, freely can adjust anterior length according to the length of user's health, and have position fixator to fix the length adjusted, such expansion link is just no longer flexible.The expansion link front end of keel front portion is fixedly connected with a pair handle and a dismountable buoyancy aid, and buoyancy aid junction is a hickey.In the middle part of keel, transition portion is hollow structure, for reducing water to its resistance.Be a long shaped plate at keel rear portion, plate being fixed one can the vacuum seal formula paddle wheel of adjusting position, and there is individual projection in heel centre position down place, is conducive to balance, is similar to structure of surfboard.

During use, fix vacuum seal formula paddle wheel at keel afterbody, pedal is connected directly between on this paddle wheel both sides axle, and vacuum seal formula paddle wheel fills water, and water inlet and delivery port are immersed in water.Because human body from having buoyancy in water, therefore utilize the buoyancy of people and front end buoyancy aid to realize people and the utility model in water float or suspension.People is prostrate on the utility model, because there is buoyancy aid front end, and the vacuum seal formula paddle wheel of rear end is all filled with water and in submergence and water, so make whole swimming aid, head is light and feet are heavy, the head of such people surfaces, the lower part of the body is then also immersed in water, and entirety sees it is prostrate in water, swims as ordinary people.Put pedal into when left and right pin to kick backward, in the process pedaled, vacuum seal formula paddle wheel paddle is driven to rotate, therefore from the water of delivery port ejection certain speed, according to the law of conservation of momentum, the utility model obtains momentum forward, because keel are stiff materials, can well power transmission, because of this person along with the utility model is pushed ahead.A waistband is had for the waist location of regular user in the middle part of keel, in time keeping straight on, people only needs both hands to hold handle to kick backward, if needs turn to, can liberate both hands and strike to the left and right, owing to there being waistband to fix, so do not worry that people is separated with the utility model.A coarse filtration net can be added in water inlet on the impact of vacuum seal formula paddle wheel to reduce pasture and water etc., in order to reach more labour-saving object, can install plastics ratchet at vacuum seal formula paddle shaft place make its single load bearing in water rotate, just as the flywheel of bicycle rear, also the inertia of rotatable paddle wheel can be utilized to obtain power even if do not scrunch when paddle wheel rotates, but because the comparison of resistance of water is large, do not reach bicycle efficient like that.
