The present invention relates to an air compression device, and more particularly to a compressed air collection device capable of collecting compressed air. Background technique

The continuous strengthening of the greenhouse effect and the deepening of the energy crisis have forced human beings to begin to face the two major problems of environmental pollution and energy shortage, and to study countermeasures and measures to alleviate and solve these problems. The development and utilization of renewable energy sources can not only reduce the consumption of traditional energy reserves on the basis of guaranteeing human energy demand, but also reduce the emissions of waste gas and waste generated by burning fossil energy, and alleviate the environment from the root cause. pollution problem. As a prominent representative of new energy sources, solar energy, wind energy, and hydropower have been used in many fields and successfully replaced fossil energy. However, in some areas, traditional energy sources are still used to provide power, and research on new energy sources is less used.

Cars are one of the most widely used products in modern society. Today, with the rapid population growth, the number of cars has increased dramatically. However, most of the current cars still use traditional fossil energy engines, which results in The consumption of fossil energy is large, and cars using traditional fossil energy engines emit a large amount of toxic gases during driving, and the pollution to the environment is quite serious.

There are already some air-powered vehicles that use air energy as power in the prior art. These cars use a different aerodynamic engine than a fossil energy engine, relying on the energy provided by high-pressure air to drive the engine and the car. This emerging air-energy vehicle does not rely on burning traditional fossil energy to obtain power. It uses only compressed air. It achieves zero emissions to the outside world during driving, and it is pollution-free and in line with development trends. Moreover, in order to reduce the number of parking inflating of the air-powered car and make the driving distance of the car larger, an air compressor is provided in the car to generate compressed air required for the aerodynamic engine, but the existing air compressors are mostly Piston structure, the air compressor of this structure keeps reciprocating oscillation during operation, so it will generate large vibration, which is not conducive to the smooth running of the car and will cause certain damage to various components. The most important thing is Piston air compressors need to consume more kinetic energy to compress the air, causing the aerodynamic engine to supply the car. The motivation is not enough.

Therefore, it is necessary to provide a compressed air collecting device having a relatively high pressure and generating compressed air. Summary of the invention

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2, the compressed air collecting device 1 of the present invention is used for supercharging and accelerating air and collecting compressed air, and the compressed air collecting device 1 includes a casing 10 having a chamber 100, which is disposed in the a rotating shaft 11 in the chamber 100 and a plurality of blades 12 mounted on the rotating shaft 11; the chamber 100 extends through the front and rear ends of the casing 10, and the side wall of the casing 10 is provided with a collecting passage 101 The one end of the collecting channel 101 communicates with the chamber 100 through an opening 102. The other end of the collecting channel 101 has an output interface 103. The fan blade 12 has a hollow structure and has a windward surface 120. An air inlet 121 is defined in the windward surface 120, and an end of the blade 12 has an air outlet 122 communicating with the air inlet 121, and the air outlet 122 faces the opening 102.

The rotary shaft 11 is rotatably disposed at a center position of the chamber 100 and is driven by an engine. When the compressed air collecting device 1 is mounted to an air powered vehicle, the rotating shaft 11 may be drivingly connected to an output shaft of the aerodynamic engine and driven by an aerodynamic engine, or may be separately provided with an electrically driven electric motor. Drive connection. Also, the mounting direction of the housing 10 is such that the windward surface 120 of the blade 12 faces the advancing direction of the air powered vehicle to allow as much airflow as possible into the chamber 100. A plurality of the compressed air collecting devices 1 may be installed on an air powered vehicle to obtain more compressed air.

Specifically, in the embodiment, eight identical blades 12 are mounted on the rotating shaft 11, and the number of the blades 12 is adjusted according to the amount of compressed air actually required, which is not limited thereto. The air inlet 121 opened in the fan blade 12 has a circular shape, and may be any other shape that facilitates air entering the blade 12. Four guide vanes 123 for guiding the airflow to the air inlet 121 are fixed around the air inlet 121, and the guide vanes 123 are in a rotating direction with the rotating shaft 11 (ie, FIG. 2 in this embodiment). Counterclockwise) corresponding bending settings. The function of the guide vanes 123 is to direct air at the periphery of the guide vanes 123 toward the air inlet 121 to make it easier for air to enter the fan blade 12 from the air inlet 121. The fan blade 12 has an air flow passage 125 and an energy storage chamber 126 disposed along a radial direction of the rotating shaft 11 , and one end of the energy storage chamber 126 and the air inlet 121 And communicating with one end of the air flow passage 125 near the rotating shaft 11 , and an end of the air flow passage 125 near the end of the blade 12 communicates with the air outlet 122 . The air entering the inside of the fan blade 12 through the air inlet 121 accumulates in the energy storage chamber 126 and is accelerated by centrifugal force. Since the accumulated mass is increased, the effect of increasing the speed boosting is more obvious. The air entering the air flow passage 125 has a certain initial pressure and an initial flow rate, which is more advantageous for subsequent supercharging acceleration.

In addition, the shape of the blade 12 is based on conventional designs well known in the art to minimize air resistance and will not be described in detail herein.

In the embodiment, the housing 10 has a circular structure, and the chamber 100 is also disposed in a circular structure corresponding to the rotational trajectory of the end of the blade 12, thereby reducing the collecting passage 101 and The distance of the end of the blade 12 makes it easier for compressed air flowing out of the air outlet 122 to enter the collecting passage 101 from the opening 102, reducing waste of compressed air.

The collecting passage 101 is an annular structure disposed around the chamber 100, and correspondingly, the opening 102 also has an annular structure that is opened around a side wall of the chamber 100. The arrangement of the collecting passage 101 around the annular structure of the chamber 100 is to increase the volume of the collecting passage 101, so that the number of the blades 12 can be increased correspondingly, so that more compressed air can enter the chamber. The collecting channel 101 is described. The opening 102 is disposed in an annular structure corresponding to the collecting passage 101 to completely open one end of the collecting passage 101, so that the blade 12 can be ensured regardless of how many the blades 12 are disposed. An air outlet 122 is opposite the opening 102 and directs compressed air into the manifold 101. In order to enhance the structural strength of the side walls of the chamber 100, a plurality of ribs may be provided to connect the side walls of the two sides of the opening 102, and the plurality of ribs isolate the opening 102 into a discontinuous annular structure.

In the axial direction of the rotating shaft 11, the collecting passage 101 is a wedge-shaped structure having a gradual change in size, and the collecting passage 101 is provided with one end of the opening 102 having a size larger than that of the collecting passage 101. One end. The other end of the collecting passage 101 is provided in a small shape to facilitate maintaining the pressure and flow rate of the compressed air.

As a more preferable arrangement, one end of the collecting passage 101 has a curved surface 104 for guiding compressed air toward the other end of the collecting passage 101, and the curved surface 104 faces the opening 102 and In a transitional action, the curved surface 104 allows compressed air entering from the opening 102 to flow gently in the direction of the collecting channel 101 without direct collision with the side wall, thereby avoiding generation The pressure and flow rate caused by turbulent flow are reduced.

As shown in FIG. 2, the setting direction of the output interface 103 in this embodiment is perpendicular to the axial direction of the rotating shaft 11, and the number of the output interfaces 103 is four, and the output interface 103 is undoubtedly set. There are a variety of settings for both direction and quantity, so I won't comment here.

As mentioned above, the compressed air collecting device 1 of the present invention can be installed in an air-powered vehicle and provides power to the vehicle - a compressed air, which can be used to directly deliver the compressed air outputted from the output port 103 to the aerodynamic engine. The cylinder, but such a direct delivery method may cause waste when the aerodynamic engine consumes very little energy, and may not meet the requirements of the aerodynamic engine when the output of the compressed air collection device 1 is insufficient. Therefore, one or more a compressed air storage device (not shown) communicating with the output interface 103, the compressed air storage device may store compressed air outputted from the output interface 103, and set a heating device to heat the compressed air Pressurize, and then output an appropriate amount of compressed air according to the consumption of the aerodynamic engine.

Compared with the prior art, the fan blade 12 having a hollow structure is disposed in the chamber 100, and the windward surface 120 of the blade 12 has an air inlet 121, and the fan blade 12 The end has an air outlet 122 communicating with the air inlet 121, so that when the blade 12 follows the rotation of the rotating shaft 11, air enters the blade 12 from the air inlet 121 and is under the action of centrifugal force After being pressurized, the fan blade 12 is separated from the air outlet 122 into the collecting channel 101, and finally output through the output interface 103. The whole process does not require volume compression of the air, so there is no need to overcome the internal air. The work is performed with less resistance, and the energy consumption is less. The centrifugal force generated by the rotation of the blade 12 accelerates and accelerates the air, and the compressed air flowing out through the air outlet 122 has a high pressure and a large flow rate, which can satisfy the use. need.
