Further, the motor is a variable frequency speed reduction motor.

Above-mentioned technical scheme through using frequency conversion gear motor, through the rotational speed of control box output current frequency control motor under the prerequisite of guaranteeing sufficient moment of torsion, can realize rotatory according to the speed range of 2 ~ 8 circles/hour, prevents rotary platform rotating stall, has reduced inertia, ensures that rotary platform rotatory speed is controllable and further improves rotary platform's stationarity.

Further, the rotary platform is designed to be circular, has a diameter of 4.5m and is 145mm away from the deck.

Above-mentioned technical scheme, circular rotary platform is more pleasing to the eye, can not give other people and cause dizzy visual effect, and this size of a dimension is according to the space size of current general boats and ships and formulate, and the commonality is stronger.

Further, in order to further improve the smoothness of the operation of the rotary platform and reduce the noise during the operation, the pulley is a rubber pulley.

Further, in order to improve the stability of the platform body connected with the deck, a central bottom plate corresponding to the central disc is arranged on the deck, and the central disc is fixedly connected with the central bottom plate through bolts.

The utility model discloses following beneficial effect has:

(1) through evenly setting up 4 motors at the marginal circumferencial direction of platform body, and then increased the rotatory drive power of rotation platform, the load of every motor of dispersion simultaneously to reduce the noise that produces during the motor operation, offset because of boats and ships slope, sway, shake and to the instantaneous effort that rotation platform brought, increased rotation platform's bearing capacity, and improved rotation platform's stationarity.

(2) Through using frequency conversion gear motor, through the rotational speed of control box output current frequency control motor under the prerequisite of guaranteeing sufficient moment of torsion, prevent the rotatory stall of rotary platform, reduced inertia, ensure that the rotatory speed of rotary platform is controllable and further improve rotary platform's stationarity.
