Abstract
The utility model relates to a paddle with an angle of advance. The paddle with the angle of advance comprises a paddle rod, a paddle head which is placed at the upper end portion of the paddle rod and a paddle blade which is placed at the lower end portion of the paddle rod, a paddle neck portion is arranged at the lower end of the paddle rod, the paddle blade is arranged at the tail end of the lower side of the paddle neck portion, the angle of advance is formed by the upper end of the paddle neck portion of the paddle with the angle of advance which is formed in a tilting and deflecting mode along the direction perpendicular to the blade surface of the paddle blade, the angle of the advance is from 10 degrees to 20 degrees, the angle of advance is generally any one of 10 degrees, 10.5 degrees, 11 degrees, 11.5 degrees, 12 degrees, 12.5 degrees, 13 degrees, 13.5 degrees, 14 degrees, 14.5 degrees, 15 degrees and 15.5 degrees, and concrete numerical value can be obtained according to experiments and detected by the experiments according to personal habits so as to obtain maximum paddle reactive force.
Description
Technical field
The utility model relates to the boats and ships device, espespecially a kind of paddle that is provided with advance angle that is provided for improving the anti-theft column lock anti-theft effect.
Background technology
Dragon-boat racing is great sports and amusement project traditional waterborne of folks of china, is the paddle contest of many people collective.dragon boat as its name suggests, is the long boat of long and narrow a, shape such as flood dragon, bandpass only can hold two people sits down side by side, takes into full account mechanics principle, makes boat resistance when paddling minimum, the sportsman divides two rows to be sitting in the middle of dragon boat, and every staff takes a quant firmly to paddle forward, team member's hand of fore takes coloured flag to take charge of commander, team member of stern takes charge of the drummer, dragon-boat racing has been spread more than 2,000 year, mostly be to hold in celebrating red-letter day, in dragon boat match at present, dragon boat paddle used is all straight slurry, ceaselessly will draw slurry in the process of sliding mentions and inserts in water after trailing forward due to needs, then firmly slide backward, slide into quant is lifted after afterbody at once after, continue to trail forward and insert in water, so constantly the action of slip is completed in circulation, this traditional straight slurry leading portion in the process of using is drawn journey when beginning, paddle is stretched over forward when inserting after amplitude peak in water, during the blade entry and the angle of the water surface excessive, paddle board can not be fully oblique cutting forward, cause the leading portion slippage shorter, and draw journey in sportsman the strongest stage casing, the too early tilted rearward of straight slurry, draw journey at back segment, because straight slurry early breaks away from the water surface, cause back segment not only rearward to produce thrust, but also upwards there is thrust in water, cause the loss of part energy, cause simultaneously dragon boat to sink, cause the increase of resistance to water-flow, collecting together of above these unfavorable factors, will inevitably cause the loss of most speed, cause the reduction of dragon boat speed.
The utility model content
Thereby technical purpose of the present utility model be for provide a kind of be provided with easily detachable structure be convenient to transport the carrying so that the paddle that is provided with advance angle of assembling at the scene.
For realizing above-mentioned purpose, a kind of paddle that is provided with advance angle of the present utility model, comprise the slurry bar, be positioned at the slurry head of slurry bar upper end and the blade of bottom, the lower end of slurry bar has the slurry neck, the downside end of neck is provided with blade, and there is an advance angle this slurry neck upper end that is provided with the paddle of advance angle along the direction tilted deflecting perpendicular to the blade face of blade.
In a kind of paddle that is provided with advance angle of the present utility model, the angle of described advance angle is between 10-20 °.
In a kind of paddle that is provided with advance angle of the present utility model, the angle of described advance angle is any one angle in 10 °, 10.5 °, 11 °, 11.5 °, 12 °, 12.5 ° 13 °, 13.5 °, 14 °, 14.5 °, 15 °, 15.5 °, 16 °, 16.5 °.
beneficial effect: the paddle that is provided with advance angle of the present utility model, owing to adopting above-mentioned technical scheme, therefore in the process that slides, its blade page with the advance angle that leans forward towards the front side to, draw the leading portion of journey in paddle, the slurries liquid level can be inserted in water in advance, can have more effectively paddle ability, draw the posterior segment of journey in paddle, the blade page can advance direction perpendicular to shipping agency in the most of the time, can upwards not dig current, the power that most energy all is converted into shipping agency, therefore can guarantee speed faster, make in the paddle process that to produce useful work more, thereby the speed of dragon boat is faster.
Description of drawings
Fig. 1, be the schematic diagram of paddle of the present utility model and existing paddle contrast;
Fig. 2, be the schematic diagram of paddle of the present utility model when the slippage of stage casing;
Fig. 3, be the schematic diagram of paddle of the present utility model in when the back segment slippage.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the present utility model, rather than whole embodiment.Based on embodiment of the present utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
please refer to Fig. 1, Fig. 2 and shown in Figure 3, as shown in FIG., a kind of paddle that is provided with advance angle of the present utility model, comprise slurry bar 11, be positioned at the slurry 1 of slurry bar upper end and the blade 12 of bottom, the lower end of slurry bar has slurry neck 15, the downside end of neck is provided with blade, there is an advance angle this slurry neck upper end that is provided with the paddle of advance angle along the direction tilted deflecting perpendicular to the blade face of blade, in the present embodiment, this advance angle angle of paddle that is provided with advance angle is usually between 10-20 °, during match, entrant's paddle of sliding on dragon boat, when the slippage of stage casing, the blade face is approximately perpendicular to the direction of advancing, therefore can obtain maximum sliding force this moment and then promote dragon boat to advance rapidly, with respect to traditional straight paddle, can not produce downward propelling thrust, therefore there is no extra strength loss, can take full advantage of entrant's muscle power, and then can greatly improve the speed of dragon boat 2.
Certainly, further, the angle of the advance angle of the paddle that is provided with advance angle of the present utility model can be 10 ° or 10.5 ° or 11 ° or 11.5 ° or 12 ° or 12.5 ° or 13 ° or 13.5 ° or 14 ° or 14.5 ° or 15 ° or 15.5 ° or 16 ° or 16.5 ° or 17 ° or 17.5 ° or 18 ° or 18.5 ° or 19 ° or 19.5 ° or 20 ° etc. angle value arbitrarily.
