Description
The utility model relates to a kind of swimming instruction device waterborne.
Existing swimming instruction waterborne is rubber band of use usually, and the one end is fixed on pool side, and the other end ties up on the athletic waistband, realizes that with the stretching resistance and the convergent force of rubber band resistance is swum and the purpose of traction acceleration swimming.But the stretching resistance of rubber band is different with convergent force in the different stages, and when promptly stretching, initial stretching resistance is very little, and elongation is big more more, and is motionless until drawing; And when reclaiming, initial convergent force is very big, diminishes gradually then, until disappearance.Also have a kind of counter weight type training aids at present, it is a kind of weighing apparatus force trainer, but will realize the training of long-distance swimming, and the volume of equipment will be very high very big, thereby very heavy.Therefore, above-mentioned two kinds of swimming instruction devices waterborne all can not adapt to the needs of modern training.
The purpose of this utility model provides a kind of swimming instruction device waterborne, and it can make the sportsman carry out the resistance swimming instruction under the power and swimming instruction is quickened in traction waiting, and simple in structure, easy to use.
The purpose of this utility model is achieved through the following technical solutions, and a kind of swimming instruction device waterborne is provided, and it comprises a long rope; Pair of brackets, their parallel interval are arranged; One roller, it is installed in rotation between the pair of brackets by turning cylinder and bearing, and an end of described long rope is fixed on the circumferential surface of roller; One hinge wheel, it is installed in an end of roller turning cylinder by unilateral bearing; One direct current motor, it is fixedly mounted on the support; One minor sprocket, it is fixedly mounted on the output shaft of direct current generator, and is connected with hinge wheel by chain.
In described swimming instruction device waterborne, also be rotatably mounted a pole in the place ahead of roller and between pair of brackets, the circumferential surface of pole is provided with the circumferential groove that is used to guide long rope.
In described swimming instruction device waterborne, at the other end of roller turning cylinder one spring case is installed, two dish springs are installed in the spring case, wherein, the inner ring of a dish spring is installed on the roller turning cylinder, and the outer ring is fixed on the spring case periphery; The inner ring of another root dish spring is installed on the spring support by spring case, and the outer ring also is fixed on the spring case periphery; And spring support is fixed on the support.
In described swimming instruction device waterborne, a photoelectric turnplate also is installed on the direct current generator output shaft, photoelectric turnplate output and motor output end are connected to nixie display respectively.
The utility model has the advantages that this swimming instruction device waterborne can make the sportsman carry out the resistance swimming instruction under the power and swimming instruction is quickened in traction waiting, and simple in structure, easy to use.When speeding up, the resistance that training aids produces also strengthens thereupon when athletic, to reach best training effect; When the sportsman migrated, training aids produced a pulling force traction that sportsman's migration speed is accelerated, to improve athletic swimming rate.
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing, so that more clearly understand above and other features and advantages of the present utility model.
Fig. 1 is that the sportsman uses the schematic diagram according to swimming instruction device waterborne of the present utility model;
Fig. 2 is the partial schematic sectional view according to swimming instruction device waterborne of the present utility model.
Referring to Fig. 1, when sportsman 1 was in pond 2, an end of a long rope 5 tied up on the athletic waistband 4, and the other end of long rope 5 is fixed on the roller 14 of swimming instruction device 7 waterborne.Direct current generator 23 on the training aids 7 can be by battery pack 9 power supplies, also available AC rectification power supply, but battery-powered safer.Nixie display 6 is installed on the case of battery pack 9.Training aids 7 and battery pack 9 can be installed on the moveable base 8, so that be placed on the suitable place on swimming pool bank 3 as required.
Referring to Fig. 2, comprise the spaced apart support 13 of pair of parallel according to a kind of swimming instruction device waterborne of the present utility model, one roller 14 is installed in rotation between the pair of brackets 13 by turning cylinder 15 and bearing 16, and an end of a long rope 5 is fixed on the circumferential surface of roller 14.One hinge wheel 18 is installed in an end of roller turning cylinder 15 by unilateral bearing 17, and a direct current motor 23 is fixedly mounted on the support 13, and a minor sprocket 25 is fixedly mounted on the output shaft 24 of direct current generator 23, and is connected with hinge wheel 18 by chain 19.
In addition, in the place ahead of roller 14 and also be rotatably mounted a pole 10 between pair of brackets 13, the circumferential surface of pole 10 is provided with circumferential groove, is used to guide long rope 5 fitly to be wound on the circumferential surface of roller 14.
One spring rope drawing machine structure is installed on the other end of roller turning cylinder 15, it comprises that one is fixed on the spring case 20 on the roller turning cylinder 15, and spring case is equipped with two dish springs 21 for 20 li, wherein, a dish spring inner ring is installed on the roller turning cylinder 15, and the outer ring is fixed on the spring case periphery; Another root dish spring inner ring is installed on the spring support 22 by described spring case 20, and the outer ring also is fixed on the spring case periphery; And spring support 22 is fixed on the support 13.When motor 23 did not have the electricity supply, the dish spring can reclaim the long rope of pulling out and be wound on the roller.
In addition, also a photoelectric turnplate 26 can be installed on direct current generator output shaft 24, the output 27 and the motor output end 28 of photoelectric turnplate 26 are connected on the nixie display 6, thus " PWM " function of energy synthesis display training athlete.
" PWM " function that nixie display 6 can reflect training athlete is set on the swimming instruction device waterborne, and the help sportsman understands training achievement and the progress of oneself intuitively, to improve athletic enthusiasm.This Presentation Function can also help coach's layout training program, formulate drill program.
The utility model adopts electromagnetic type resistance principle, promptly when the sportsman swims in the water, by 14 counter-rotatings of long rope 5 pulling rollers, make motor 23 counter-rotatings by chain 19 thus, and rotor produces resistance when rotating in magnetic field, and the motor of this moment is passive counter-rotating, is equivalent to a generator, and rotating speed high-drag more is big more, and the big I of the range of resistance of training aids obtains by the regulator generator output loading.When the sportsman returns, connect power supply, motor 23 is rotated, drive roller 14 and just changeing the long rope 5 of withdrawal, the speed of receiving rope is greater than athletic swimming rate, thereby with certain strength pulling motion person swimming, the speed of traction swimming and strength can obtain by regulating rotating speed of motor and power.
Spring rope drawing machine structure and motor are received rope and can and be used and noncontradictory.When battery pack there was not electricity, the drag effect of training aids 7 remained unchanged, and can utilize spring rope drawing machine structure and receive when restricting.
