Title:
FLOW GUIDE APPARATUS AND DIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/104129
Kind Code:
A1
Abstract:
Disclosed in the present invention are a flow guide apparatus and a diving device. The flow guide apparatus is used for the diving device. The diving device comprises a thruster body and a ducted propeller; the flow guide apparatus is provided between the thruster body and the ducted propeller; the flow guide apparatus is provided with a water inlet end and a water outlet end, the water inlet end is provided on the side of the flow guide apparatus close to the thruster body, the water outlet end is provided on the side of the flow guide apparatus close to the ducted propeller, the water inlet end is communicated with the water outlet end, and a water flow channel is formed; a first flow guide structure is provided between the water inlet end and the water outlet end; the first flow guide structure is provided with a first flow guide surface; the first flow guide surface is set in an arc shape; the first flow guide surface is used for guiding a water flow towards the ducted propeller. The flow guide apparatus stably guides a water flow towards the ducted propeller, so that the technical problems of excessive energy loss and unstable flow field occurring when the water flow enters the ducted propeller are solved, and the effects of reducing energy loss and improving the working efficiency of the ducted propeller of the diving device are achieved.
