Description

wheel paddle

technical field

The utility model relates to a ship propeller, in particular to a wheeled paddle arranged on a ship.

Background technique

In existing various transmission ratios and related toy designs, there is not yet a propeller that revolves with the wheel disc and can rotate itself. The paddle blades on pedal boats that are commonly used at present are fixed on the turret. The biggest disadvantage of the paddle blades is that when they enter the water, they draw water downwards and when they exit the water, they lift the water upwards. The energy loss is large, resulting in low speed of the boat. . 2003.01.08, the Chinese Patent Office published a utility model patent named "pressurized water type ship propeller". and rear push rod composition. Its application can greatly reduce the turbulence caused by the fast rotation of the propeller, saving energy and thus reducing operating costs. Due to the reduction of fuel consumption, the pollution to the environment can also be reduced; in addition, it can also avoid the entanglement of the propeller by foreign objects, affect the progress of the ship, and protect the wild life in the water. And its design and manufacturing costs are much lower than propeller propellers. Afterwards, on May 28, 2003, the Chinese Patent Office published a utility model patent named "a ship propeller". In order to solve the problem of radial flow caused by the centrifugal force of water generated by the conventional propeller propeller when the propeller rotates, which reduces the working efficiency, a cylindrical fairing is arranged around the propeller, and the outer chord of each blade of the propeller and the inner wall of the fairing The fixed connection uses the fairing to block the radial flow of the water flow, so that it can move completely in the axial direction, so that the efficiency of the propeller can be improved. The above-mentioned patents all solve the problem of propeller propeller thrust efficiency reduction due to the loss of rotational energy to a certain extent, but all have the disadvantages of complex structure, inconvenient use, and unsuitable for manufacturing and promotion.
