Embodiment Construction

[0019] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as Figure 1-3 As shown, a propeller 10 used in water includes: a sealed casing 11 , a controller 13 , a motor 14 , a battery 15 and a pump jet propeller 16 . The controller 13 and the battery 15 are installed in the sealed casing 11 . A motor 14 is fixed to one end of the sealed case 11 . The pump jet propeller 16 is connected to the motor 14 and driven to rotate by the motor 14 . Both the motor 14 and the controller 13 are electrically connected to a battery 15 . The battery 15 can provide power for the controller 13 and the motor 14 . The controller 13 controls the motor 14 to rotate, and the rotation of the motor 14 drives the pump jet propeller 16 to realize the propulsion operation.

[0021] As a further structure, the sealed housing 11 includes: a body 111 and an end cover 12 . The motor housing 141 of the motor 1...

Abstract

The invention discloses a propeller used in water. The propeller comprises a sealing shell, a controller, a motor, a battery and a pump jet propeller body. The controller and the battery are arrangedin the sealing shell. The motor is fixed to one end of the sealing shell. The pump jet propeller body is connected to the motor and is driven by the motor to rotate. The motor and the controller are electrically connected to the battery. The sealing shell comprises a body and an end cover. A motor shell of the motor is connected to one end of the body so as to seal one end of the body. The end cover is connected to the other end of the body to seal the other end of the body. The end cover comprises an outer end cover and an inner end cover. The inner end cover is in threaded connection with the other end of the body. A threaded hole is formed in the inner end cover. A bolt is arranged on the inner side of the outer end cover. The outer end cover is screwed into the threaded hole through abolt to be fixed to the outer side of the inner end cover. The end cover of the propeller used in water is provided with the inner end cover and the outer end cover, the structure is simple, dismounting is convenient, later maintenance is convenient, and meanwhile the sealing performance of the sealing shell is improved.

Description

technical field [0001] The invention relates to a propeller used in water. Background technique [0002] The hermetic casing of a conventional thruster is sealed by an end cover. However, the end cover structure of the traditional thruster is too simple, and its connection structure is not convenient for users to disassemble, and it is also inconvenient for production and subsequent disassembly and maintenance. Contents of the invention [0003] The invention provides a propeller used in water, which adopts the following technical scheme: [0004] A propeller used in water, comprising: a sealed casing, a controller, a motor, a battery and a pump-jet propeller; the controller and the battery are installed in the sealed casing; the motor is fixed to one end of the sealed casing; the pump-jet propeller Connected to and rotated by the motor; both the motor and the controller are electrically connected to the battery; the sealed housing includes: a body and an end cover; the ...
