Abstract

The invention relates to an underwater propeller, which comprises a power part and a propeller. The power part is arranged at the upstream of the propeller and is used for driving the propeller to rotate. The underwater propeller further comprises a water inlet part and a water outlet part, wherein the power part is arranged on the upstream or the interior of the water inlet part, a water inlet isformed in the water inlet part, one end and the other end of the water inlet part are columnar, and the diameter of the radial section where one end of the water inlet part is located is gradually increased from the diameter of the radial section where the other end of the water inlet part is located; the water outlet part is arranged at the downstream of the water inlet part, and a water outletis formed in one end of the water outlet part. The water inlet part is adjacent to the propeller and is arranged at the upstream of the propeller, and the propeller is arranged in the water outlet part. By improving the structure of the underwater propeller, the guide stability of the underwater propeller in use is improved, and the kinetic energy utilization rate is increased.

Description

technical field [0001] The invention relates to the field of water sports equipment, in particular to an underwater propeller. Background technique [0002] Underwater thrusters, also called frogman boosters, are one of the important aids for frogmen or swimmers in shallow sea diving, and are more and more favored by users abroad. The underwater thruster includes a battery, a control device, a drive motor and a transmission device. The control device controls the connection of the power supply, and the battery supplies power to the drive motor. The drive motor drives the propeller through the transmission device, and the propeller rotates to push the underwater booster forward. [0003] Chinese patent CN107472484A discloses an underwater propeller, including an impeller, a casing, an inner chamber, and a driving device. The impeller is set inside the casing near the water outlet at the bottom; the driving device is set in the inner chamber, and the drive shaft of the drivin...
