Abstract

This invention discloses a drag reduction and thrust reversal device, relating to the field of fluid dynamics technology. The invention includes a front drag reduction air intake assembly, an automatic rotary cutting assembly, two fluid delivery pipes, and the drag reduction and thrust reversal assembly. The automatic rotary cutting assembly is mounted on the front drag reduction air intake assembly. In this invention, the drag reduction and thrust reversal device, composed of the front drag reduction air intake assembly, the automatic rotary cutting assembly, the fluid delivery pipes, and the drag reduction and thrust reversal assembly, efficiently captures oncoming fluid through an inclined inlet at the front.

This converts oncoming resistance into propulsive power, directly propelling the ship forward, achieving the dual effects of drag reduction and thrust reversal, and converting drag energy into forward propulsion.

Description

Technical Field

[0001] This invention relates to the field of fluid dynamics technology, specifically to a drag reduction and reverse thrust device. Background Technology

[0002] During operation, wind resistance and water resistance are the main causes of energy loss and reduced range efficiency for various high-speed transportation vehicles (such as cars, ships, and airplanes). Currently, the industry generally adopts passive shape design or additional power compensation to deal with drag. Such solutions cannot convert oncoming drag into effective propulsion, and have limited support for drag reduction and attitude stabilization under extreme flight conditions. Meanwhile, in the field of ship navigation, a low-pressure negative pressure zone is easily formed at the stern of the ship. The drag force generated by this negative pressure zone is the core factor that hinders the ship's speed increase and increases energy consumption. Existing technologies often only focus on drag reduction at the front end, neglecting the elimination and conversion of negative pressure at the stern, which limits the improvement of ship energy efficiency. To address the aforementioned problems, the inventors proposed a drag-reducing reverse thrust device. Summary of the Invention

[0003] In order to solve the above problems, the purpose of this invention is to provide a drag reduction reverse thrust device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a drag reduction and reverse thrust device, the drag reduction and reverse thrust device comprising a front drag reduction air intake assembly, an automatic rotary cutting processing assembly, two fluid delivery pipes and a drag reduction and reverse thrust assembly; The automatic rotary cutting processing component is mounted on the front drag reduction air intake component, and the fluid delivery pipeline is located between the front drag reduction air intake component and the drag reduction reverse thrust component.

[0005] Preferably, the front-end drag-reducing air intake assembly includes two water inlet channels, which are inclined and have a water inlet at one end. A filter baffle is installed at the water inlet.

[0006] Preferably, the automatic rotary cutting assembly includes a rotating shaft, and several rotating shafts are provided. The several rotating shafts are rotatably installed at one end of the water inlet channel near the water inlet. Several blades are fixedly arranged in a ring array at both ends of the rotating shaft, and several rotary cutting blades are fixedly arranged in a ring array in the middle of the rotating shaft.

[0007] Preferably, the drag reduction and thrust reverser assembly includes two end delivery pipes. One end of the fluid delivery pipe is fixedly located at the end of the water inlet channel away from the water inlet, and the other end of the fluid delivery pipe is fixedly located at one end of the end delivery pipe. The other end of the end delivery pipe is equipped with a tail jet booster device.

[0008] Preferably, the tail spray booster device includes any one of a vector nozzle, a spiral nozzle, and a water hammer nozzle.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, a drag reduction and reverse thrust device, consisting of a front drag reduction air intake assembly, an automatic rotary cutting assembly, a fluid delivery pipeline, and a drag reduction and reverse thrust assembly, efficiently captures the oncoming fluid through the inclined water inlet at the front end. The filter baffle at the inlet blocks large debris, and the fluid-driven rotary cutting blades rotate and cut the debris and mix it. The mixture is then delivered to the end delivery pipeline through the fluid pipeline. Under the action of the tail jet pressurization device, the fluid forms a vortex and is ejected at high speed, generating reverse thrust. This converts the oncoming resistance into propulsion power, directly propelling the ship forward. This achieves the dual effects of drag reduction and reverse thrust, converting drag energy into forward propulsion. 2. In this invention, the drag reduction and reverse thrust device, which consists of a front-end drag reduction air intake component, an automatic rotary cutting component, a fluid delivery pipeline, and a drag reduction and reverse thrust component, has a compact structure and high energy efficiency. It is applicable to various fluid media such as liquids, gases, and plasmas, and can be widely used in all structures that move in fluids, such as ships, underwater vehicles, aircraft, aerospace vehicles, circular moving bodies, and high-speed moving equipment, to achieve drag reduction, deceleration, environmental isolation, and functional protection. 3. In this invention, by using tail jet pressurized injection, the low-pressure negative pressure zone formed at the stern of the ship is directly counteracted and eliminated, and the negative pressure drag force that was originally a drag force is converted into forward thrust.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Example: Figs. 1-2 As shown, the present invention provides a drag reduction and reverse thrust device, which includes a front drag reduction air intake assembly 1, an automatic rotary cutting processing assembly 2, two fluid delivery pipes 3 and a drag reduction and reverse thrust assembly 4. The automatic rotary cutting processing assembly 2 is disposed on the front drag reduction air intake assembly 1, and the fluid delivery pipes 3 are disposed between the front drag reduction air intake assembly 1 and the drag reduction and reverse thrust assembly 4.

[0016] The front-end drag-reducing air intake assembly 1 includes two water intake channels 11, which are inclined. In use, the two inclined water intake channels 11 are mounted on the side of the ship and fit against the hull. One end of the water intake channel 11 is provided with a water inlet 12. Since the water intake channel 11 is inclined, the water inlet 12 is also inclined, which can efficiently capture oncoming air or water flow. The inclined structure guides the fluid in smoothly, reducing the impact drag at the front of the ship. A filter baffle 13 is installed at the position of the water inlet 12. By setting the filter baffle 13, large debris such as leaves, branches, and plastic sheets can be blocked from entering the interior of the water intake channel 11, preventing the subsequent pipes from being blocked and protecting the core mechanical structure.

[0017] The automatic rotary cutting processing component 2 includes a rotating shaft 21. Several rotating shafts 21 are rotatably installed at one end of the water inlet channel 11 near the water inlet 12. Several blades 22 are fixedly arranged in a ring array at both ends of the rotating shaft 21. When air or fluid enters the interior of the water inlet channel 11 through the water inlet 12, the flow rate of the air or fluid impacts the blades 22, causing the rotating shaft 21 to rotate. Several rotary cutting blades 23 are fixedly arranged in a ring array in the middle of the rotating shaft 21. When the rotating shaft 21 rotates, it can cause the rotary cutting blades 23 to rotate. The rotary cutting blades 23 can chop up small impurities (such as broken leaves, mud, etc.) after filtration, ensuring that the impurities are fully mixed with the fluid and ensuring the smooth flow of the downstream channel.

[0018] The drag reduction and thrust reverse assembly 4 includes two end delivery pipes 41. One end of the fluid delivery pipe 3 is fixedly located at the end of the water inlet channel 11 away from the water inlet 12, and the other end of the fluid delivery pipe 3 is fixedly located at one end of the end delivery pipe 41. The fluid delivery pipe 3 is used to stably and rapidly transport the mixture of shredded fluid and impurities to the interior of the end delivery pipe 41. The other end of the end delivery pipe 41 is provided with a tail spray booster device 42, which includes any one of a vector nozzle, a spiral nozzle, and a water hammer nozzle. When air or fluid enters the interior of the end delivery pipe 41, the tail jet booster device 42 receives the mixed medium sent from the fluid delivery pipe 3 and guides and accelerates it inside the end delivery pipe 41, causing the fluid to form a vortex state. The fluid accelerated by the vortex is ejected at high speed from the tail nozzle of the end delivery pipe 41. The ejection of the fluid generates a reverse thrust opposite to the direction of the ship's forward movement, thereby converting the original head resistance into the power to propel the ship forward. At the same time, it can directly counteract and eliminate the low-pressure negative pressure zone formed at the stern of the ship, converting the negative pressure drag force that was originally a drag force into forward thrust.

[0019] Working principle: When in use, this device is installed on both sides of the ship. The device moves with the ship. The wind / water coming from the front is quickly sucked in by the inclined water inlet 12. Large debris is blocked by the filter baffle 13 at the water inlet 12 and cannot enter the interior of the water inlet channel 11. The air or fluid flow impacts the blade 22, causing the blade 22 to rotate. At this time, the rotating shaft 21 rotates, causing the rotary cutting blade 23 to rotate. The rotary cutting blade 23 cuts up the small impurities (such as broken leaves, mud, etc.) after filtration, ensuring that the impurities are fully mixed with the fluid and ensuring the smooth flow of the downstream channel. The mixed fluid is sent to the end delivery pipe 41 through the fluid delivery pipe 3. The tail jet booster device 42 receives the mixed medium sent through the fluid delivery pipe 3 and guides and accelerates it inside the end delivery pipe 41, causing the fluid to form a vortex. The fluid accelerated by the vortex is ejected at high speed from the tail nozzle of the end delivery pipe 41. The ejection of the fluid generates a reverse thrust opposite to the direction of the ship's forward movement, directly propelling the ship forward. This achieves the dual effects of drag reduction and reverse thrust, converting drag energy into forward power. At the same time, under the action of the tail jet booster device 42, it directly counteracts and eliminates the low-pressure negative pressure zone formed at the stern of the ship, converting the negative pressure drag force that was originally a drag force into forward thrust.

[0020] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
