Target.

At present, the bionic propulsion applied in the field of ships, taking the application number CN201510307414.3 as an example of a fishtail propulsion device suitable for small waterplane area catamarans, the design stability of the mechanism is poor, and it is prone to fatigue. Have not yet seen that there is a power unit that imitates the swing of a dolphin as a ship propulsion by a rocker mechanism.

Contents of the invention

The object of the present invention is to provide a dolphin-like marine propulsion device, which is easy to control, easy to maintain and simple to process and manufacture, aiming at the characteristics of dolphin tail swing.

The object of the present invention is achieved like this: comprise bracket, the motor that is installed on the bracket, the rear gear that is installed on the motor output shaft, the front gear that is installed on the bracket, upper rocker, lower rocker, triangular connecting rod and water Wing, the rear gear meshes with the front gear, the rear gear and the front gear are respectively provided with a rear link and a front link, one end of the lower rocker is hinged with the hydrofoil, and the other end of the lower rocker passes through the corner of the triangular link The pin is set on the bracket, the end of the rear link is hinged with the lower rocker, the end of the front link is hinged with one end of the triangular link, one end of the upper rocker is hinged with the other end of the triangular link, and the other end is connected with the installation Hinge on the hinge support on the hydrofoil.

Compared with the prior art, the beneficial effect of the present invention is: the present invention designs a motor through the transmission of the connecting rod and the rocker by studying the swing characteristics of the dolphin's tail, so that the hydrofoil can realize the motion of imitating the dolphin's tail. attitude. The mechanical structure design and manufacturing of the connecting rod and rocker are relatively simple, which makes the function of the whole device easy to realize. In addition, a motor is used as the power system, and the expected motion track of the hydrofoil is realized through relatively simple mechanical transmission, and its control is easy to realize.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The invention is a dolphin-like marine propulsion device, which is mainly used in the field of ships, and includes a motor providing power, hydrofoils, connecting rods, triangular connecting rods, rockers, pins, gears, brackets, and hinge supports. The device of the present invention is installed on the bracket through the motor. In order to clearly describe the interconnection relationship between the various components, the spatial positional relationship installed by each component will be described as follows: the front gear and the rear gear, the front connecting rod and the rear connecting rod, the upper Rocker and lower rocker. The rear gear is directly mounted on the motor, and the front gear is mounted on the bracket through a pin, and the two gears can be meshed. One end of the front link is connected to the front gear through a pin, and the other end is hinged to the triangular link through a pin. The corner of the triangular link and one end of the lower rocker are installed on the bracket through a pin, the other end of the triangular link is hinged with the upper rocker through a pin, and one end of the rear link is installed on the rear gear through a pin. The other end of the rod is hinged with the lower rocker through a pin, the other end of the upper rocker is the rear end is hinged with the hinge support installed on the hydrofoil through a pin, and the other end of the lower rocker is the rear end of the rocker. One end is hinged with the hydrofoil through a pin, the device drives the gear to move through the motor, the gear drives the connecting rod to move through the pin, the two connecting rods drive the rocker and the triangular connecting rod respectively, and the triangular connecting rod drives the other rocker to move. The combination of the two joysticks drives the hydrofoil to produce a movement effect like a dolphin's tail fluttering up and down, thereby generating thrust.

In conjunction with the drawings, the motor 1 is installed on the bracket 20, the gear 2 is installed on the motor 1, the gear 3 is installed on the bracket 20 through the pin 6, and the connecting rod 7 and the connecting rod 8 are respectively installed on the bracket 20 through the pin 4 and the pin 5. On the gear 2 and the gear 3, the other ends of the connecting rod 7 and the connecting rod 8 are respectively connected with the rocking bar 10 and the triangular connecting rod 11 through the pin 14 and the pin 15, and the rocking bar 9 is connected with the triangular connecting rod 11 through the pin 12, and the rocking bar 10 and triangle connecting rod 11 are installed on the support 20 by pin 13, and the other end of rocking bar 10 is connected with hydrofoil 19 by pin 16, and the other end of rocking bar 9 is connected with hinge support 18 by pin 17, and hinge support 18 Fixed on the hydrofoil 19.

Motor 1 drives gear 2 to rotate, gear 2 drives gear 3 to rotate, gear 2 and gear 3 drive connecting rod 7 and connecting rod 8 to move through pin 3 and pin 5 respectively, and connecting rod 7 and connecting rod 8 are driven by pin 14 and pin 15 The rocker 10 and the triangle connecting rod 11 move, the triangle connecting rod 11 drives the rocker 9 to move through the pin 12, the rocker 10 drives the hydrofoil 19 to move up and down through the pin 16, and the rocker 9 passes through the pin installed on the hinge support 18 17 drives hydrofoil 19 to rotate around pin 16. The hydrofoil 19 is driven by the combination of the rocking bar 9 and the rocking bar 10 to perform a synthetic motion of swinging up and down and rotating around the pin 16, so as to produce the effect of the swing of the dolphin's tail and generate propulsion.

The invention includes motors, hydrofoils, connecting rods, triangular connecting rods, rockers, pins, gears, brackets, hinge supports and other related components that provide power. The two connecting rods drive the rocker and the triangular connecting rod to move respectively, and the triangular connecting rod drives the other rocker to move. The combination of the two rocking rods drives the hydrofoil to produce a movement effect like a dolphin's tail fluttering up and down, thus can generate thrust.
