Problems solved by technology

[0003] The lateral propeller in the prior art usually adopts a single propeller, and the thrust is not equal during forward and reverse rotation, resulting in inconsistent propulsion efficiency. In the actual use process, it is easy to generate a rotating wake, and it is easy to make the ship unstable when traveling.

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1~5 , the present invention provides a technical solution: an underwater thruster, including a housing 1, the housing 1 is used to install the first underwater special propulsion motor 3, the second underwater special propulsion motor 5 and the third underwater propulsion motor. Lower the carrier of the special propulsion motor 6 to drive the hull to move. Both sides of the housing 1 are provided with a duct 2, and the two ends of the duct 2...

Abstract

The invention discloses an underwater propeller. The underwater propeller comprises a shell; ducts are arranged on the two sides of the shell; first underwater special propulsion motors are mounted atthe two ends of the ducts; the two groups of first underwater special propulsion motors are arranged far away from each other; second underwater special propulsion motors and third underwater specialpropulsion motors are correspondingly mounted at the two ends of the bottom and the two sides of the bottom of the shell; a storage battery box is mounted in the shell; cameras and illumination lampsare mounted at the two ends of the shell; a sonar sensor is mounted at the bottom of the shell; and a detachable storage battery is mounted in the storage battery box. In the ducts on the two sides of the shell, the first underwater special propulsion motors are arranged far away from each other to be beneficial for the propeller to drive a hull to move forwards and backwards; the second underwater special propulsion motors and third underwater special propulsion motors are correspondingly mounted at the front and rear parts of the bottom of the shell and on the two sides of the bottom of theshell to balance the propeller from front to rear and from left to right; and the balance of the propeller is automatically kept so that the balancing effect of the hull is improved.

Description

technical field [0001] The invention relates to the technical field of ship propulsion, in particular to an underwater propeller. Background technique [0002] A propeller is a device that converts any form of energy into mechanical energy. Thrust is generated by rotating blades or jets of air (water). It can be used to drive vehicles forward, or as a power source for other devices such as generators. Thruster control circuits are commonly used in power propulsion systems, such as surface vessels, platforms, underwater robots, motion platforms, and propulsion systems and positioning systems for land-based motor-driven walking platforms. [0003] The lateral propeller in the prior art usually adopts a single propeller, and the thrust is not equal during forward and reverse rotation, resulting in inconsistent propulsion efficiency. In the actual use process, it is easy to generate a rotating wake, and it is easy to make the ship unstable when traveling. To this end, we prop...
