Problems solved by technology

Low thrust vectoring, especially when the vehicle turns and its thrust is lost
[0004] In addition, due to the complex situation on the seabed and the harsh environment, the requirements for the maneuverability of underwater robots are extremely high. Most underwater robots cannot fully meet the above action requirements
In order to change the propeller propulsion mode of the underwater robot, the direction of the propulsion force can be changed by relying on the rudder. The propulsion force can only be changed in one direction of rotation. When the underwater robot needs to change the depth and the forward course; The rudders in the two directions of the wing and the vertical wing are controlled, and the flexibility of movement is greatly limited
[0005] Secondly, in order to improve flexibility and maneuverability, it is also designed to install multiple propeller propellers on the underwater robot, which are respectively arranged around the underwater robot, but this method will increase the complexity of the mechanical system and increase the cost. , and some propellers will only start when the underwater robot turns, and most of them are idle under normal circumstances, resulting in a waste of resources
[0006] In summary, there is an urgent need for an underwater vectoring thruster that can realize flexible steering, simple structure, and low manufacturing cost, and there is no report about this underwater vectoring thruster

Embodiment 1

[0040] In order to facilitate the understanding of the technical solution of the present invention, the following description uses the term "Coanda effect", which is also called wall adhesion or Coanda effect. The fluid (water flow or air flow) tends to deviate from the original flow direction and flow along the surface of the protruding object instead. When there is surface friction between the fluid and the surface of the object it flows through, as long as the curvature is not large, the fluid will flow along the surface of the object, and the water will flow against its wall.

[0041] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an underwater vector thruster that utilizes the Coanda effect to realize flexible steering in the present invention. An underwater vector thruster that uses the Coanda effect to realize flexible steering, the underwater vector thruster includes a housing 1, a vector motor 2, a main propulsion motor 3, a main channel...

Embodiment 2

[0053] Please refer to Figure 5 , Figure 5 It is a structural schematic diagram of another underwater vector thruster that utilizes the Coanda effect to realize flexible steering of the present invention. An underwater vector propeller that utilizes the Coanda effect to realize flexible steering, the underwater vector propeller includes a housing 1, a vector motor 2, a main channel 4, an attached flow channel 5, a hollow shaft 6 and a partition 7; The vector motor 2 has a propeller; the end of the hollow shaft 6 is hemispherical; the hollow shaft 6 is connected to the housing 1 through the partition 7; the space between the housing 1 and the hollow shaft 6 through the partition 7 is the main flow Channel 4; the attached flow channel 5 is a channel formed by the inner wall structure of the housing 1; the attached flow channel 5 is connected to two symmetrical main flow channels 4; the main flow channel 4 is provided with a vector motor 2; The vector motor 2 is arranged symm...

Abstract

The invention relates to an underwater vector propeller for realizing flexible steering by utilizing coanda effect. The underwater vector propeller comprises a casing, a main propelling motor, vector motors, mainstream channels, a subsidiary stream channel, a main propeller stream channel and partition boards, wherein the main propelling motor is mounted in the main propeller stream channel; each of the vector motor is provided with a screw propeller; the connecting spaces of the casing and the main propeller stream channel through the partition boards are used as the mainstream channels; the subsidiary stream channel is a channel formed by the structure of the inner walls of the casing; the subsidiary stream channel is connected with the two symmetrical mainstream channels; the vector motors are respectively arranged in the mainstream channels; two ends of the casing are in an opening structure. The underwater vector propeller for realizing flexible steering by utilizing the coanda effect, disclosed by the invention, has the advantages that when ships, submarines, unmanned underwater robots and the like need to swerve, the vector propelling can be realized through changing the rotational speed of different vector motors, so that the flexible underwater propelling control can be realized.

Description

technical field [0001] The invention relates to a novel underwater vector thruster, in particular to an underwater vector thruster which can realize flexible steering and is applied to various ships, submarines, torpedoes, and underwater unmanned robots. Background technique [0002] At present, human beings are facing three major problems of population, resources and environment. Among them, the natural resources consumed by human beings are decreasing day by day, which makes people start to explore the ocean, which covers two-thirds of the earth. Resources and petroleum resources, in recent years, countries all over the world are stepping up research and development of marine resources. Its marine detection equipment is an important tool for seabed detection. Therefore, marine detection equipment such as ships, submarines, torpedoes, and underwater drones have emerged as the times require. [0003] With the continuous development of the offshore industry, especially the ...
