[0021] See also Figures 1-2 In this embodiment, a well-mounted symmetrical propeller is provided, including a propeller seat 2. The rear end of the propeller seat 2 is installed on the ship through an auxiliary mounting frame 1, and is fixed in a well-type manner through an I-beam steel frame, so as to ensure that the power of the propeller seat 2 when driven can be stably transmitted to the ship for driving. A drive cabin 5 is fixedly installed at the lower end of the propeller seat 2, and a drive group 3 is built in the drive cabin 5. The drive group 3 is limitedly arranged in the middle of the propeller seat 2. Propeller compartments 4 are symmetrically fixedly installed on the left and right sides of the propeller seat 2.

A plurality of water inlet holes 43 are equidistantly provided on the propeller compartment shell 41 and the arc-shaped ring 42. The arc-shaped ring 42 is used to reduce the cross-sectional area of ​​the channel, thereby accelerating the flow rate of driving water inlet, and cooperating with the water inlet hole 43 and the water inlet ring 7 to perform high-pressure water inlet, thereby increasing the propulsion driving force.

The spiral top shaft 61 is movably installed on the left and right sides of the driving cabin 5, and the propeller impeller 62 is staggered and fixedly installed on the spiral top shaft 61. The staggered propeller impeller 62 moves in coordination on the spiral top shaft 61, thereby maintaining the stability of the water intake flow, reducing flow negotiation interference, ensuring the flow rate, and through the symmetrical structure, the propeller impellers 62 on the left and right sides are propelled by water intake in the same direction, increasing the water flow rate, and ensuring the propulsion power of the ship.
