Background

With the development of the times and the advancement of science and technology, vehicles used by people are as follows: the speed of airplanes, high-speed rails and automobiles is continuously increased, the front ends of the objects moving at high speed are the surfaces which are contacted with the maximum wind resistance, and the running speed and the energy consumption of the moving objects are directly influenced due to the generation of the wind resistance. At present, although the front ends of the moving objects are provided with the tip streamline structures, certain wind resistance is reduced, the effect is poor, and the problem is not fundamentally solved. How to solve the influence of wind resistance on a moving object, achieve the purposes of saving energy, improving efficiency and realizing the rapid operation of the moving object is a problem to be solved urgently at present.

Furthermore, the wind bag is a funnel-shaped or leak-groove-shaped shell with a hollow structure.

The method for realizing the anti-wind resistance by using the device comprises the following steps: the wind bag which is hollow and funnel-shaped or leak groove-shaped is connected with the front end of the moving object through the connecting body and the connecting sheet to move together; forming a device which can lead the atmospheric pressure to generate pressure difference at the opening of the wind bag and the tail part of the moving object; the wind pocket pockets air, flows through the clearance and acts on the convex inclined plane at the front end of the moving object; the surface pressure of the convex inclined plane is reduced under the action of high-speed airflow to form negative pressure smaller than atmospheric pressure, and suction is generated at the front end of a moving object; the rear end of the moving object is pushed by atmospheric pressure; the air resistance changes the direction between suction and pushing, and becomes power, thereby realizing the effect of resisting wind resistance.

Detailed Description

The method of the invention comprises the following steps:

1) the obtained wind pocket 1 is a hollow shell with two open ends, wherein the open area of one end is larger than that of the other end, and the two open ends are connected by an arc line;

2) the wind bag 1 is arranged on a convex inclined plane at the front end of the moving object 4, and the end with a large opening of the wind bag 1 is positioned in front of the moving object 4;

3) when the wind bag 1 moves along with the moving object 4, atmospheric pressure difference can be generated between the opening of the wind bag 1 and the tail part of the moving object 4, the direction of air resistance is changed by utilizing the atmospheric pressure difference, and the resistance is changed into power, so that the anti-wind resistance effect is realized.

The invention utilizes the funnel-shaped or leak-groove-shaped wind bag 1 with a hollow structure to be connected with the front end of a moving object 4 for movement; forming a device which can enable atmospheric pressure to generate atmospheric pressure difference at the opening of the wind bag and the tail of the moving object; the wind pocket pockets air, flows through the clearance and acts on the convex inclined plane at the front end of the moving object; the surface pressure of the convex inclined plane is reduced under the action of high-speed airflow to form negative pressure smaller than atmospheric pressure, and suction is generated at the front end of a moving object; the rear end of the moving object is pushed by atmospheric pressure; the air resistance changes the direction between suction and pushing, and becomes power, thereby realizing the effect of resisting wind resistance.

The following provides further details of embodiments of the apparatus of the present invention with reference to the accompanying drawings:

referring to fig. 1, since air is not subjected to a shearing force but can be subjected to an area pressure, the movement of the object is always blocked. In order to overcome air resistance, the shape of the moving object is thinned and pointed, and streamline processing is carried out, so that partial resistance can be reduced, but the effective area of the object cannot be reduced again and again, and the air resistance always falls on the effective area of the moving object; the resistance is only delayed a little bit, the reduction is instantaneous resistance, the total resistance is not really reduced, and finally the resistance is added to the effective area of the moving object. Especially, the front end of the moving object, especially the critical part of the wind resistance, must be solved. The nature of the resistance is wind resistance formed by airflow, and the wind resistance is also a force, but the direction of the wind resistance is opposite to the moving direction of the object; since the force is in the opposite direction, all the contradictions and problems are solved by changing the direction of the force, and the idea of anti-wind resistance is obviously the best method for completely eliminating air resistance.

Therefore, the invention relates to a wind resistance device for the front end of a moving object, which comprises a wind bag 1, a connecting body 2 and a convex inclined plane at the front end of the moving object 4, wherein the wind bag 1 is a hollow shell with two open ends, the open area of one end is larger than that of the other end, and the two open ends are connected by an arc line; a connecting piece connected with a moving object 4 is arranged in the wind bag 1; the connecting piece comprises a connecting body 2 and a connecting piece 3, the connecting body 2 is arranged at the front end of a moving object 4, the wind bag 1 is sleeved on the connecting body 2 through the connecting piece 3, the front end of the moving object is provided with a convex inclined plane, and the end, with a large opening, of the wind bag 1 is positioned in front of the moving object 4; the wind bag 1 is a funnel-shaped or leak-groove-shaped hollow shell; the inner wall of the wind bag is connected with a convex inclined plane at the front end of a moving object 3 through a connecting sheet 3 and a connecting body 2, and a gap for air circulation is arranged at the connecting part; the shorter inclined plane arranged on the inner surface of the tail part of the wind bag 1 corresponds to the convex inclined plane at the front end of the moving object 4; the wind bag 1 is used for holding airflow in the incoming flow direction, the movement speed of the airflow is accelerated under the action of the inclined plane of the funnel, and the accelerated airflow passes through the gap of the inner wall of the shell and acts on the convex inclined plane at the front end of the moving object 4; the convex inclined plane at the front end of the moving object 4 is correspondingly matched with the shorter inclined plane on the inner surface of the tail part of the wind pocket 1, so that the convex inclined plane of the moving object forms negative pressure on the surface under the action of airflow, and the negative pressure generates suction to the moving object; when no wind pocket exists, the acting force of the incoming flow on the moving object 4 is reverse thrust and is positive pressure; after the wind pocket 1 is arranged, the acting force of the incoming airflow on the moving object 4 is negative pressure and is suction force; thereby realizing the purpose of changing the acting force direction of the airflow.

The wind pocket 1 is used at the front end of traffic transport tools such as automobiles, high-speed trains and airplanes, has a remarkable energy-saving and speed-increasing effect, and has a very important meaning.

The above description is only exemplary of the preferred embodiments of the present invention, and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
