Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1 to 4, the present embodiment comprises the guiding mechanism 4 of power-driven mechanism 1, two piston crank mechanisms that phase place is contrary 2, two pairs of paddle blade mechanisms 3 and paddle blade movement, embodiment illustrated in fig. 2 one is arranged in underdeck cabin 7 for the present invention completely, embodiment illustrated in fig. 3 two are arranged in underdeck cabin 7 for setting unit of the present invention, can determine according to actual conditions.Power-driven mechanism 1 is arranged in hull, the piston crank mechanism 2 that two phase places are contrary is separately positioned on power-driven mechanism 1 both sides, respectively be arranged on hull front and back end before transverse axis 5 or rear cross shaft 6 be connected, in the middle part of front transverse axis 5 or hinged with the guiding mechanism 4 being set in parallel in cabin 7 both sides respectively in the middle part of rear cross shaft 6, front transverse axis 5 two ends or rear cross shaft 6 two ends are connected with paddle blade mechanism 3 is vertical respectively.
Power-driven mechanism 1 comprises motor reducer combination 11, intermeshing first conical gear 12, second conical gear 13 and transmission shaft 14, motor reducer combines 11 two ends and is supported in cabin 7 respectively by support 111, the output shaft of motor reducer combination 11 is fixedly connected with the first conical gear 12, and the transmission shaft 14 that the second conical gear 13 is supported in cabin 7 respectively by drive axle support 141 with two ends is fixedly connected with.
Piston crank mechanism 2 comprises eccentric wheel 21 and connecting rod 22, and transmission shaft 14 two ends are fixedly connected with eccentric wheel 21 respectively, and transmission shaft 14 two ends are supported in cabin 7 respectively by transmission shaft support 141.Connecting rod 22 one end and eccentric wheel 21 wheel rim hinged, the other end respectively with corresponding before in the middle part of transverse axis 5 or hinged in the middle part of rear cross shaft 6.Paddle blade mechanism 3 comprises paddle blade axle 31 and a pair can the paddle blade 32 of folding, and paddle blade axle 31 upper end is fixedly connected with front transverse axis 5 or rear cross shaft 6 termination, lower end and a pair can paddle blade 32 side of folding hinged.
As shown in Figure 4, guiding mechanism 4 comprises guide rail 41 and orienting lug 42, and guide rail 41 is set in parallel in cabin 7 both sides, is supported in cabin 7 respectively by several guide supporting seat 43.Guide rail 41 is the bathtub construction of middle opening, and orienting lug 42 is T-type structure, described T-type structure upper end respectively with front transverse axis 5 in the middle part of or hinged in the middle part of rear cross shaft 6, T-type structure lower end is embedded in bathtub construction, with bathtub construction sliding block joint.
As shown in Figures 2 and 3, the eccentric wheel 21 of piston crank mechanism 2 that two phase places are contrary becomes rotational symmetry with hinge-point B1 with B2 of connecting rod 22 with drive axle support 141 line of centers C1-C2, with ensure two connecting rods 22 that motor reducer combines 11 both sides promote respectively before transverse axis 5 and rear cross shaft 6 do the contrary movement in direction.If front transverse axis 5 moves to ship's head, then rear cross shaft 6 moves to stern direction; Vice versa, thus drive and the paddle blade 32 of folding also can do relative movement a pair.When the paddle blade axle 31 be connected with front transverse axis 5 two ends moves to ship's head, a pair paddle blade 32 is closed under hydraulic pressure effect on front side of paddle blade axle 31, meanwhile, the paddle blade axle 31 be connected with rear cross shaft 6 two ends moves to ship stern direction, a pair paddle blade 32 is opened under hydraulic pressure effect on front side of it, rear cross shaft 6 continues to move to ship stern direction, and rear cross shaft 6 two ends drive a pair paddle blade 32 such as frog propelling fluid of striking to move backward respectively, thus make boats and ships sailed onward.Moved backward by the opening and closing of paddle blade 32 and movement progress fluid backward, thus produce boats and ships sailed onward propulsive force.When current transverse axis 5 moves to ship's head, a pair paddle blade 32 at its two ends closes, and now rear cross shaft 6 moves to ship stern direction, and a pair paddle blade 32 at two ends is opened and struck; When current transverse axis 5 moves to ship stern direction, a pair paddle blade 32 at its two ends is opened, and now rear cross shaft 6 moves to ship's head, and a pair paddle blade 32 at its two ends closes; Front transverse axis 5 and rear cross shaft 6 continuously alternately open coupled paddle blade 32, and propelling fluid moves backward, make boats and ships sailed onward, improve the efficiency of ship's navigation.
In order to strengthen the support to front transverse axis 5 or rear cross shaft 6, the present invention has also set up the auxiliary rod 8 be rectangular in shape, and auxiliary rod 8 one end is fixedly connected with connecting rod 22, the other end respectively with front transverse axis 5 or rear cross shaft 6 hinged.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
