Embodiment

[0043] Please refer to Figure 1-5 , this embodiment provides a Coanda effect propulsion system 1000 . The Coanda effect propulsion system 1000 includes: an effect valve, a water injection power unit 300 and a regulating power unit 400 .

[0044] The effect valve includes a water spray tube 100 and a control ring 200. The water spray tube 100 has an inner cavity, and one end of the water spray tube 100 is provided with a water inlet 110 communicating with the inner cavity.

[0045] The water spray tube 100 also has multiple groups of effect openings, and the multiple groups of effect openings are arranged at intervals along the circumference of the water spray tube 100 . Each group of effect openings includes a first opening and a second opening communicating with the inner cavity. The first opening is opened on the side wall of the water spray tube 100 , and the second opening is opened on the end of the water spray tube 100 away from the water inlet 110 . Along the axial d...

Abstract

The invention provides a coanda effect propelling system and an underwater robot and relates to the field of underwater robots. The propelling system comprises a water spray barrel, a control loop, awater spray power device and an adjusting power device. An inner cavity is formed in the water spray barrel, and a water inlet is formed in one end of the water spray barrel. Multiple sets of effect openings formed in the circumferential direction of the water spray barrel are formed in the water spray barrel, each set of the effect openings comprises a first opening and a second opening, the first openings are formed in the side wall of the water spray barrel, and the second openings are formed in the end, away from the water inlet, of the water spray barrel. The water spray barrel is sleevedwith the control loop. A control opening is formed in the control loop. A water outlet of the water spray power device communicates with the water inlet. The adjusting power device is in transmissionconnection with the control loop so as to adjust rotation of the control loop and control an effect valve to be turned on and off. The robot comprises the above coanda effect propelling system. The robot and the coanda effect propelling system are simple in structure, good in stability and low in energy consumption, the output direction of a jet stream can be flexibly adjusted, and multi-freedom-degree motion is achieved.
