Most of the traditional ship propelling devices adopt propellers, although the propellers are convenient to drive, the efficiency is low, the manufacturing process of the blades is complex, and the underwater part comprises a transmission part, so that the maintenance is inconvenient; the traditional paddle wheel propulsion device has the water beating phenomenon when in use, the water splash is large, the effective thrust does not exceed a half period, the water resistance is large just after water enters the paddle and just before water exits, the energy loss is large, the efficiency is low, and the noise is large.

Disclosure of Invention

The invention aims to overcome the defects of the existing ship propelling device and invents a ship propelling device with simple and efficient structure.

The technical scheme adopted by the invention is as follows:

one runner is provided with 1 or a plurality of rotatable paddles, the rotating shaft of each paddle is vertical to the water surface, and the ratio of the rotation speed of each paddle to the rotation speed of the runner is 1: 2, the blades can generate thrust components in the same direction in the 360-degree rotation process.

The technical scheme of the invention is characterized in that: 1 or a plurality of the paddles are movably connected with the rotating wheel, and the paddles can rotate relative to the rotating wheel; the direction shaft is nested in a central hole of the rotating wheel, is coaxial with the rotating wheel and is connected with the paddle transmission device; the direction control device can drive the direction shaft to rotate relative to the rotating wheel driving device; the rotating wheel driving device can drive the rotating wheel to rotate relative to the direction shaft; when the rotating wheel rotates relative to the direction shaft to drive the blades to revolve along with the rotating wheel, the blade transmission device drives the blades to rotate relative to the rotating wheel in a direction of 1: 2 to spin.

When the direction control device drives the direction shaft to rotate for an angle, the initial angle of the paddle plane synchronously rotates, and the integral propelling direction of the paddle is synchronously changed, so that 360-degree control of the propelling direction is realized.

Paddle transmission can adopt the gear drive scheme, including paddle gear, intermediate gear, direction gear, every the paddle with one paddle gear fixed connection, the direction gear with direction axle fixed connection, every the intermediate gear with runner swing joint and respectively with direction gear and one the transmission of paddle gear meshing, the paddle gear with the gear ratio of direction gear is 2: 1.

paddle transmission also can adopt synchronizing wheel synchronous belt drive scheme, including paddle synchronizing wheel, direction synchronizing wheel, hold-in range, every paddle with one paddle synchronizing wheel fixed connection, direction synchronizing wheel and direction axle fixed connection, every paddle synchronizing wheel passes through the hold-in range and is connected with the direction synchronizing wheel, and the gear ratio of paddle synchronizing wheel and direction synchronizing wheel is 2: 1.

in practical implementation of the present invention, the blade transmission device may also adopt more transmission modes such as bevel gears and the like, which are not listed here.

Has the advantages that:

the invention provides a ship propulsion device capable of controlling the direction by 360 degrees, which has the advantages of high propulsion efficiency, simple direction control and low noise; in addition, only the plane paddle is arranged below the waterline, and no transmission part is arranged, so that the failure rate is low, the maintenance is convenient, and the disassembly and the assembly are easy. The invention can be applied to various ships and can be installed on various pools and water tanks to be used as a flow making device.
