DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-8 , the embodiment of the present invention includes: A gaseous or liquid speed-up and energy-saving range-extending mechanism is only used to cooperate with a driving device 5 to increase thrust, and does not output power itself. Its structure includes: a guide part body 1, a hollow cavity, a front arc-shaped guide part 2, a rear arc-shaped guide part 3, and a curved guide groove 4.

[0020] Since the front arc-shaped guide part of the guide part guides the fluid evenly and quickly around, and then closely adheres to and quickly flows through the outer peripheral wall of the guide part body, the fast fluid increases the backward thrust. The length a of the guide part body is greater than the diameter b of the guide part body, preferably, a=(2~3)*b. The diameter b of the guide part body is less than or equal to the diameter c of the drive device, that is, b≤c.

[0021] Wherein, the guide part body can be a cylindrical structure.

[0022] The guide body is arranged behind the propeller, jet engine and other driving devices along the fluid direction so that the guide body faces the driving device, and the minimum distance d between the guide body and the driving device is less than or equal to the guide body b, that is, 0<d≤b (optimal distance).

[0023] A hollow cavity is provided in the main body of the guide part, and the hollow cavity can be used to store air or helium to reduce the weight of the entire mechanism.

[0024] Further preferably, the guide body can be made of a variety of materials such as rubber, stainless steel, titanium alloy, cast steel, carbon fiber, etc., preferably a high temperature resistant, lightweight or high strength material.

[0025] The cross-sections of the front arc-shaped guide portion and the rear arc-shaped guide portion are semi-elliptical structures. The front arc-shaped guide portion and the rear arc-shaped guide portion are symmetrically arranged at the front and rear ends of the guide portion body, and the connection between the guide portion body and the front arc-shaped guide portion and the rear arc-shaped guide portion adopts arc chamfers for natural transition. The front arc-shaped guide portion faces the driving device, and the rear arc-shaped guide portion faces away from the driving device. The front arc-shaped guide portion with a certain curvature allows the fluid in the front to flow smoothly and quickly to the surroundings, and then the rear arc-shaped guide portion is used to concentrate the fluid to increase the thrust.

[0026] That is, through the cooperation between the arc-shaped guide surface and the guide part body, the efficiency of fluid acceleration can be improved. The faster the flow rate, the greater the thrust, thereby reducing energy loss and increasing cruising range.

[0027] Further preferably, the radian of the front arc-shaped flow guide and the rear arc-shaped flow guide can be the radian of the two sides of an ellipse with an ellipse eccentricity between 0.6 and 1 or the radian of the two ends of an oblate ellipse. Among them, ellipses are divided into oblate ellipses and round ellipses. Oblate ellipses: ellipses with an eccentricity close to 1 but less than 1, with a large ratio between the major axis and the minor axis, and the ellipse is relatively flat; round ellipses: ellipses with an eccentricity close to 0, with a long axis and a short axis of similar length, and a shape closer to a circle.

[0028] Further preferably, the guide body and the front and rear arc-shaped guides are an integrated structure to form a guide body. The guide body can also be an overall ellipsoid structure.

[0029] Further preferably, the guide body can be installed by a connecting and fixing mechanism, wherein the connecting and fixing mechanism includes a hollow hanger, a connecting rod, and the like.

[0030] Two or more curved guide grooves are axially arranged on the guide body, and both ends of the curved guide grooves are open structures. The curved guide grooves make the airflow rotate, extend the distance of the jet, and increase the thrust. The twist angle of the curved guide grooves is between 4°C and 8°C. The number, depth and curvature of the curved guide grooves can be adjusted according to the size of the guide body and the usage scenario.

[0031] Further preferably, the carrier surface shape of the curved guide groove can be square, triangular or other shapes, and the beginning or end of each curved guide groove gradually transitions from the outer surface of the guide body to the deep layer to the middle layer of the outer surface, that is, the depth at the starting position of the curved guide groove will gradually deepen from the outer surface of the guide body until it transitions to the middle layer of the outer surface of the guide body, and the depth at the ending position of the curved guide groove will gradually decrease from the middle layer of the outer surface of the guide body until it transitions to the outer surface of the guide body, and the main body depth of the curved guide groove remains consistent.

[0032] Further preferably, the depth of the curved guide groove can be adjusted according to the actual use environment and needs. Among them, on the same range-extending mechanism, the depth of the curved guide groove can be consistent, just like the depth of the threads around a screw; the depth of different range-extending mechanisms is different. For example, when used underwater, the depth of the curved guide groove can be deeper, and the depth of the curved guide groove on the drone can be shallower.

[0033] Further preferably, when a plurality of curved flow guide grooves are provided on the flow guide body, the curved flow guide grooves need to be evenly distributed around the flow guide body. The larger the diameter of the flow guide body, the more evenly distributed curved flow guide grooves there are; the smaller the diameter, the fewer evenly distributed curved flow guide grooves there are. There is no fixed limit on the spacing of the curved flow guide grooves. The denser the distribution of the curved flow guide grooves, the faster the rotation speed of the generated rotating fluid; the sparser the distribution of the curved flow guide grooves, the slower the rotation speed of the generated rotating fluid.

[0034] Further preferably, Figure 3 and Figure 4 As shown, the thrust generated by the guide body with the curved guide groove is greater than the thrust generated by the guide body with a smooth surface.

[0035] The guide body with a smooth surface: The jet fluid will flow backward along the surface of the guide body in a curved manner, but will not rotate. Since the jet fluid itself has a certain air pressure or water pressure, after leaving the guide body, the jet fluid will continue to flow backward in a straight line and gradually spread out to the surroundings. Since the thrust is not concentrated, the farthest jet distance will be correspondingly shorter, so the thrust to the rear will also be relatively reduced.

[0036] A guide body with a curved guide groove: After using the curved guide groove, the jet fluid will flow backward along the surface of the guide body in a rotating manner. When the fluid leaves the guide body, it will continue to flow backward in a rotating manner. At this time, a low-pressure area will appear in the central area of ​​the rotating fluid. Due to the existence of the low-pressure area, the fluid leaving the guide body is not easy to disperse to the surroundings, and the energy is more concentrated, resulting in the rotating fluid The jet distance is farther than the farthest jet distance of the non-rotating straight fluid, so the thrust will also be greater. The longer the jet distance, the greater the thrust.

[0037] Use scenario 1 like Figure 5 As shown, when the mechanism is used on a jet aircraft, the guide body can be horizontally mounted and fixed on the aircraft wing directly behind the engine through a bracket. The outer surface of the guide body can be a smooth structure, or a curved guide groove can be provided. The hollow cavity is filled with air, and small air holes are provided on the rear half of the guide body. Because the exhaust temperature of the jet engine is very high, the guide body will expand and explode if there are no small air holes. At this time, the guide body can be made of titanium alloy, chrome-molybdenum steel, martensitic stainless steel and other materials with light weight and high strength.

[0038] When the engine is started, the airflow output by the engine is first evenly dispersed through the front arc-shaped guide part, then flows closely and quickly through the surrounding guide cylindrical surfaces (rotated through the curved guide grooves), and finally is guided and gathered by the rear arc-shaped guide part to extend the jet distance and increase the thrust.

[0039] Use scenario 2 like Figure 6 As shown, when the mechanism is used on a vertical take-off and landing aircraft such as a drone, the guide body can be fixed on the fuselage below the propeller through a connecting rod, wherein the connecting rod directly penetrates the top and tail of the guide body for fixing. The outer surface of the guide body is a smooth structure, and a curved guide groove can also be provided, and helium is filled in the hollow cavity. The guide body can be made of rubber, polyethylene plastic film, polyester film and other materials.

[0040] When the propeller rotates, the airflow first passes through the front arc-shaped guide part to be evenly dispersed, then closely adheres to and quickly flows through the surrounding guide cylindrical surfaces (rotated through the curved guide grooves), and finally passes through the rear arc-shaped guide part to guide and gather to achieve thrust enhancement.

[0041] Use scenario three like Figure 7 As shown, when the mechanism is used on a composite wing aircraft, the guide body can be directly fixed on the fuselage directly behind the engine, the outer surface of the guide body can be a smooth structure, or a curved guide groove can be provided, and the hollow cavity is filled with helium. At this time, the guide body can be made of light-weight, high-strength rubber or polyethylene plastic film or polyester film.

[0042] Use scenario 4 like Figure 8As shown, when the mechanism is used on a ship, the guide body can be fixed on the rudder blade 6 directly behind the engine through a connecting rod / bracket, and can swing with the rudder blade; the outer surface of the guide body can be a smooth structure, or a curved guide groove can be provided; since the buoyancy of water can greatly reduce the influence of the guide body's own weight on the rudder blade, the guide body can be a hollow structure or a semi-hollow structure, so that the buoyancy of water is equal to the weight of the guide body. In addition, its material can also be made of corrosion-resistant, high-strength cast steel, stainless steel, copper-nickel alloy and composite materials such as carbon fiber reinforced plastic.

[0043] When the propeller rotates, the water flow first passes through the front arc-shaped guide part to be evenly dispersed, then flows closely and quickly through the surrounding guide cylindrical surfaces (rotated through the curved guide grooves), and finally passes through the rear arc-shaped guide part to guide and gather to achieve thrust enhancement.

[0044] The beneficial effects of a gaseous or liquid speed-increasing and energy-saving range-increasing mechanism of the present invention are: 1. Cooperating with the driving device, the front arc-shaped guide part improves the uniformity and efficiency of the fluid (air or liquid) diversion dispersion, so that the fluid can flow smoothly and quickly to the surroundings, and then closely adhere to and quickly flow through the surrounding guide cylindrical surfaces. The faster the flow rate, the greater the thrust. Finally, the rear arc-shaped guide part is used to guide and concentrate the fluid, effectively improving the thrust of the fluid; 2. The curved guide groove allows the jet fluid to flow backward in a rotating manner along the surface of the guide body to form a rotating fluid behind the guide body. The central area of ​​the rotating fluid is a low-pressure area. The low-pressure area can reduce the escape of the fluid and make the energy more concentrated, thereby extending the maximum jet distance of the rotating fluid. The longer the jet distance, the greater the thrust, thereby achieving the effect of effectively increasing speed, reducing energy loss, and increasing cruising range.

[0045] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
