Secondary to run through universal driving shaft 1107 and output shaft 1106, i.e., the output end of above-mentioned rotating mechanism includes universal driving shaft 1107 and/or output shaft
1106, in at least a part of cavity through blade 1101 of output shaft 1106；Output shaft 1106 in present embodiment is set
It is set to hexagonal tubing string, universal driving shaft 1107 is set as resistance arm rotation axis, the structure phase of the cavity of blade 1101 and the hexagonal tubing string
Adaptation, when output shaft 1106 is rotated, blade 1101 does week under the drive of output shaft 1106, with output shaft 1106
To synchronous rotation, when needing to adjust water resistance, screw rod drives blade 1101 to rise or fall, and output shaft 1106 is motionless, blade
1101 rise or fall movement (being axially moved along output shaft 1106) relative to output shaft 1106, in addition to above-mentioned
Outside implementing, only need blade 1101 can be with 1106 axial relative movement of output shaft and circumferential clocking of turbine movement；In addition, with moving axis
Component fixation is set on universal driving shaft 1107,1116 one end of drawstring be arranged in drive shaft assembly one end, drawstring 1116 it is another
End is provided with grip part 1117, and drawstring 1116 is wound around the directive wheel 1242 for being set to suspended portion 124, and extends suspended portion
124 delivery outlet, grip part 1117 can be hung on the hook 1241 for being fixedly mounted on suspended portion 124.
Wherein above-mentioned drive shaft assembly includes stretch cord iron set 1110, freewheel clutch 1111 and belt wheel 1112, bullet
Power rope iron set 1110 is fixed together with freewheel clutch 1111, the stretch cord iron set 1110 and freewheel clutch 1111
Fixation is set on the universal driving shaft 1107, and belt wheel 1112 is fixed to be set in stretch cord iron set 1110 and freewheel clutch 1111
Outside is connected on mounting plate 1113 outside the belt wheel 1112 by bearing, and the mounting plate 1113 is fixedly connected on water tank
1115 is external, wherein one end of drawstring 1116 is fixedly mounted on one end of belt wheel 1112, and stretch cord 1118 is fixedly mounted on belt wheel
On 1112 other end；When trainer holds and pulls grip part 1117, rotation of the drawstring 1116 with movable belt pulley 1112, this
When, stretch cord iron set 1110, freewheel clutch 1111, universal driving shaft 1107 and output shaft 1106 do circumferential clocking of turbine rotation together, into
And the rotation of blade 1101 is driven, when trainer looses one's grip, under the action of stretch cord 1118, stretch cord 1118 carries out reset fortune
It is dynamic, belt wheel 1112 is restored to home position, at this point, also back shrinkage, stretch cord iron cover 1110, overdrive clutch to drawstring 1116
Device 1111, universal driving shaft 1107 and output shaft 1106 do the rotation of circumferential clocking of turbine in contrast together, to complete once to training
Effect.
In addition, in the present embodiment, in order to preferably make blade 1101 during rising or falling, reducing position
It moves and deviates and smoothly synchronize the case where rising or falling, set between the bottom and the intracavitary bottom of blade 1101 of output shaft 1106
It is equipped with an elastic component 1108, the elastic component 1108 of the present embodiment is pressure spring, when raised, since axial direction does not occur for output shaft 1106
Displacement, and axial displacement occurs for blade 1101, pressure spring is constantly compressed；And when declining, pressure spring is gradually recovered deformation quantity, blade
1101, by the pressure being self-possessed with pressure spring, gradually complete descending motion.
In conclusion whole adjusting water resistance process is divided into 1101 decline process of 1101 uphill process of blade or blade；On
When rising, the output of motor 1105 drives adjusting screw rod 1102 to rotate, and nut 1114 is fixed, universal driving shaft 1107 and output shaft 1106
Fixed, the axial ascending motion of adjusting screw rod 1102, blade 1101 also rises with it under the support of supporting spring 1109, at this point,
Elastic component 1108 is gradually compressed；When decline, reversely output drives adjusting screw rod 1102 to rotate to motor 1105, and nut 1114 is fixed
Motionless, universal driving shaft 1107 and output shaft 1106 are fixed, the axial descending motion of adjusting screw rod 1102, and elastic component 1108 is gradually extensive
Complex variable, blade 1101 do descending motion by the pressure of self weight and elastic component 1108.
Specifically using as follows:
S1: a certain amount of water (but cannot be toward the inner topped up with water of water tank 1115), lid be added from the water inlet of water tank 1115 first
Upper water plug stops operation of pouring water after the intracavitary water of water tank 1115 reaches certain depth；
S2: water resistance size as needed drives the rotation of adjusting screw rod 1102, and then lifting/lowering blade by motor 1105
1101 with the contact area of water, when blade 1101 and the contact area of water are bigger, then the water resistance generated is also bigger, works as blade
1101 is smaller with the contact area of water, then also just smaller in the water resistance generated；
S3: after adjusting the contact area of blade 1101 and water, by gripping and pulling grip part 1117, at this point,
By the rotation with movable belt pulley 1112 of drawstring 1116, belt wheel 1112 drives stretch cord iron set 1110 and freewheel clutch 1111
Circumferential clocking of turbine rotation, and then universal driving shaft 1107 and the rotation of 1106 circumferential clocking of turbine of output shaft, output shaft 1106 is driven to drive blade
1101 carry out circumferential clocking of turbine rotation.
S4: when unclamping grip part 1117, due to the effect of internal stretch cord 1118, belt wheel 1112 is restored to initially
Position, drawstring 1116 also start to bounce back.
S5: being repeatedly performed the operation of step S3 and step S4, thus the simulated training rowed the boat.
It should be understood by those skilled in the art that foregoing description and the embodiment of the present invention shown in the drawings are only used as illustrating
And it is not intended to limit the present invention.
The purpose of the present invention has been fully and effectively achieved.Function and structural principle of the invention is opened up in embodiment
