Paddle screw propeller type pleasure boat in sitting around type
Technical field
The present invention relates to integrating body-building, play and social pleasure-boat on a kind of park or large-scale lake surface or the offshore beach, the sit around foot-operated propeller type pleasure-boat of talk and amusement of particularly a kind of many people annular.
Background technology
At present, when people played in the park, the water cycle of being taken was generally unidirectional type side by side, by one or two stretcher power being delivered to the water extraction leaf wheel drive by transmission shaft advances, exist binding character, can not take into account everyone individual character, can not talk face to face and amusement and recreation.
Summary of the invention
Purpose of the present invention is to overcome the shortcoming of aforementioned existing pleasure-boat, provides a kind of several people to sit around and talks face to face and amusement and recreation together, and each one can step pedal for the body-building purpose and promote the paddle screw propeller type pleasure boat in sitting around type that ship is advanced simultaneously.
The technical scheme that the present invention addresses the above problem is:
A kind of paddle screw propeller type pleasure boat in sitting around type, 1 its component part comprises hull, be fixed on seat on the hull, by the visitor scrunch pedal that pleasure-boat is advanced, the screw propeller that drives through transmission device by pedal and the steering hardware of control ship direct of travel, hull is provided with a circle or oval-shaped desk, some the seat of identical or different height around the desk setting, each seat has a pedal, and described transmission device is made up of sprocket wheel, chain, the circular universal coupling transmission device, bevel-gear pair and the universal drive shaft that are provided with ratchet.
Described circular universal joint comprises: center cross, cross axle sleeve, connecting panel, key axle and on ratchet, bearing fixing support, each key axle is end to end, constitutes the universal joint of a circle.
Circular universal coupling transmission device parts are fixed on the ring support, and pedal and sprocket wheel are screwed on the pedal frame with bolt, and pedal frame is connected with ring support, and ring support is fixed on the hull.
Described steering hardware comprises: the bearing circle that is positioned at passenger's right hand place, stern middle part, the main gear of bearing circle lower end, with gear from gear, with two parallel draw bars of captiveing joint from gear, the other end of two parallel draw bars connects and to turn to rudderpost and to turn to rudder.
The invention has the beneficial effects as follows:
1. many people heighten the enjoyment around taking a seat;
2. collect body-building, fat-reducing, talk, discussion and meeting among amusement and recreation;
3. adopt circular universal coupling transmission device and ratchet device, each sprocket shaft is transferring power independently of each other, and everyone can independently trample pedal and participate in driving or rest, does not have influence each other;
4. no relative displacement motion except that rotating between the master and slave moving axis.

The specific embodiment
Referring to each accompanying drawing, be the foot-operated spiral pleasure-boat that one six people's annular is sat around.Hull 5 is provided with a round table 1, six seat 2 is provided with around round table 1.Each seat has pedal 9.The visitor occupies stably the back both feet and is placed on the pedal 9, and both hands can be placed on the round table 1.Both feet are stepped on pedal 9 forward, and the sprocket wheel of fixing with pedal 9 27 rotates by the ratchet 13 that chain 26 drives on the key axles 36, and key axle 36 also rotates.The six roots of sensation (or more than six roots of sensation) key axle 36 is end to end, constitutes a round universal coupling transmission device.
Be fixed on a bevel gear wheel 15 on the key axle 36 and drive bevel pinion 16 rotations, bevel pinion 16 drivening rods 18 rotate, and connecting rod 18 drives prop shafts 19 rotations, and prop shaft 19 drives hull 5 outer screw propellers 8 and rotates.By the transmission of a series of like this power, promote ship and advance.Owing to ratchet flywheel 13 has been installed on the key axle, everyone is imput power separately all, can six people together steps on pedal and drives screw propeller and rotate, and laborsaving speed again is fast.The people who is sitting in stern is responsible for steering dish 3, the direct of travel of control ship.
Make hull 5 with glass-felt plastic, running part and support thereof are made of metal.
Circular universal coupling transmission device is a kind of extension to two universal joints, mainly is made up of imput shaft, driven shaft, center cross, gusset piece etc.Said circular universal coupling transmission device in the present embodiment is that the principle according to single, double universal joint joins end to end key axle 36, forms circularly, comes a kind of mechanism of common transmitting movement and power.
Fig. 3 demonstrates the circular fixed support of transmission device 6 parts in the present embodiment.Pedal 9 and sprocket wheel 27 usefulness bolts are screwed on the pedal adapter plate 32, and pedal adapter plate 32 is connected with ring support 11 by pedal frame 29, is fixed on the hull 5.Six roots of sensation key axle 36 head and the tail mutually connects, and is installed on the transmission shaft adapter plate 30 that joins with pedal fixed support 29, tightens by bolt.
Fig. 6 is the steering hardware schematic diagram in the present embodiment.Bearing circle 3 is positioned at stern middle part visitor's right hand place, there is a main gear 20 lower end of bearing circle 3, be meshed with it one is fixedly connected with two parallel draw bars 22 and 23 from gear 21, the other end of these two pull bars extends downwardly into outboard, captives joint with the rudder 6 that turns to of screw propeller 8 rear ends by turning to rudderpost 24.The outside clickwise bearing circle 3 of passenger, lower end gear 20 is clickwise also, 21 left-hand revolutions of another gear, left side pull bar 22 moves backward, right side pull bar 23 moves forward, and drives to turn to rudder 6 to rotate to rudderpost 24 left-hand revolutions, and ship is just deflection to the right under flow action.Like this, just finished ship turning to the right.If the inside left-hand revolution of bearing circle, ship then left-handed turning to.
