[0002] Existing mechanical devices, such as agricultural and industrial equipment, fishing equipment, etc., mostly use fuel or electric energy as the driving energy for operation. Fuel equipment generates kinetic energy by burning gasoline or diesel to drive the engine to rotate, and then drives the action execution mechanism that can convert kinetic energy into mechanical actions to operate. The disadvantage of fuel equipment is that it will generate carbon dioxide exhaust gas after combustion, which is the source of global warming; while using electric drive, large-scale ones consume a lot of electricity, and the existing battery capacity is limited and the duration is not long. To operate for a long time, multiple batteries need to be prepared in advance and replaced alternately, the operation is cumbersome, there are certain potential electrical safety hazards, and the electricity cost is not low.

[0016] A secondary impact channel, whose direction is an arc line that bends and extends from the edge of the core body inward and then to the edge again. Each secondary impact channel communicates with the two adjacent driving recesses corresponding to the outer ring, and forms an N-stage flow channel along the circumferential direction of the core body, where N is a natural number greater than or equal to 2;

[0017] Each stage of the flow channel and the corresponding driving recess on the outer ring cooperate to form a multi-stage stroke structure with decreasing air flow energy.

[0018] Further, the secondary impact channel includes a return channel and a communicating stroke channel. The return channel communicates with the corresponding driving recess on the outer ring, and the stroke channel communicates with another driving recess.

[0019] Still further, the direction of the intake channel of the core body is a logarithmic spiral line extending from the middle to the outside. The pole of the logarithmic spiral line is set on the central axis of the core body, and the logarithmic spiral line has a direction angle of 15° - 45°.

[0020] Still further, an intake channel is provided on the core body, and its direction is a logarithmic spiral line extending from the middle to the outside.

The driving recesses are communicated with the second-stage flow channel, and then return to the second-stage flow channel and act on another driving recess of the outer ring, and so on, until the air flow is discharged from the exhaust passage. The whole process proceeds in the forward direction along the rotation direction of the outer ring, with large torque, high transmission efficiency, high air flow utilization rate, and the output torque further increases with the increase of the rotational speed.

[0032] At the same time, the flow channels arranged circumferentially on the core body effectively reduce the volume of the overall device. The more the air inlet flow channels are arranged on the core body, the lower the overall weight. It further improves the output speed and efficiency of the device, and has the characteristics of high wind flow utilization rate, large torque, high rotational speed, and high transmission efficiency. The power equipment driven by wind power does not need to adopt a structure driven by power or fuel, and to a certain extent, it can replace or assist the power equipment driven by power or fuel, realizing the utilization of clean energy and laying a foundation for the future utilization of clean energy.

With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0047] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0048] Embodiment 1

[0049] A power device driven by wind power provided in this embodiment is specifically a net-receiving device in the fishing field, including an action execution mechanism capable of converting kinetic energy into mechanical actions and a driving mechanism providing kinetic energy. Specifically, the action execution mechanism is only a mechanism capable of converting kinetic energy into mechanical actions, rather than a mechanism like a generator that converts mechanical energy into kinetic energy.

[0050] Referring to Figure 1 As shown, the net-receiving mechanism of the net-receiving device is the action execution mechanism. The net-receiving mechanism includes a winding wheel 51 and a guiding wheel 52. The guiding wheel 52 is arranged above the fishing boat deck. The winding wheel 51 and the driving mechanism are both arranged on the deck. The net-receiving line of the fishing net 53 bypasses the guiding wheel 52 and is fixedly connected to the winding wheel 51.

[0051] Continuing to refer to Figures 2 to 5 As shown, the driving mechanism includes a gas power device. The gas power device includes: an outer ring 1, on the inner circumferential surface of which a plurality of driving recesses 11 are provided in the circumferential direction; a core body 3, which is coaxially arranged inside the outer ring 1 and can rotate relative to the outer ring. At least one jet port 301, at least one exhaust port 302, and at least one secondary impact channel 300 located between the jet port and the exhaust port are provided on the outer circumferential surface of the core body 3;

[0052] At least one intake channel 31, which communicates with at least one jet port 301; and

[0053] At least one exhaust channel 310, which communicates with at least one exhaust port 302;

[0054] The air flow enters from the intake channel 31, is sequentially ejected through the jet port 301 and the secondary impact channel 300 of the core body 3, acts on at least two driving recesses 11 on the circumference of the outer ring 1, generates a thrust on these driving recesses 11 to push the outer ring 1 to rotate and do work, realizing continuous power output. Finally, the air flow is discharged through the exhaust port of the core body 3 via the exhaust channel. The gas power device further includes a shaft 2, and the outer ring 1 and the core body 3 are coaxially arranged on the shaft 2.

[0055] As Figure 4 shown, the intake channel 31 and the exhaust channel 310 are formed inside the core body 3. The jet port 301 and the secondary impact channel 300 on the core body 3 communicate with the corresponding driving recesses 11 of the outer ring 1. Among them, the secondary impact channel 300 is arranged in an alternating manner with the corresponding driving recesses 11 and is sequentially connected. The secondary impact channel 300 is arranged along the circumferential direction of the core body or the outer ring.

[0056] As Figure 5 , the core body 3 includes: an intake channel 31, which forms a jet port 31 on the circumferential surface of the core body. Its trend is an arc line extending from the middle to the outside. The jet port 301 communicates with the corresponding driving recess 11 of the outer ring, forming the first-stage flow channel;

[0057] The secondary flow channel 300 has a curved line that extends from the edge of the core body 3 inward and then bends and extends to the edge. Each time the flow channel 300 is connected to the front and rear driving recesses 11 corresponding to the outer ring 1, forming an N-stage flow channel along the circumferential direction of the core body, where N is a natural number greater than or equal to 2. It should be noted that: if it is a 2-stage flow channel, it includes the first-stage flow channel (intake channel) and the second-stage flow channel (secondary flow channel); if it is a 3-stage flow channel, it includes the first-stage flow channel (intake channel), the second-stage flow channel (secondary flow channel), and the third-stage flow channel (another secondary flow channel),...

[0058] Each stage of the flow channel cooperates with the corresponding driving recess of the outer ring to form a multi-stage stroke structure with decreasing air flow energy.

[0059] According to the requirements of the load, the gas power device can be designed. The core body 3 can be provided with a 2-stage flow channel, a 3-stage flow channel, or more stages of intake air flow channels. Each stage performs cyclic work, and the energy is fully utilized to maximize the use efficiency to meet the requirements of output torque and rotational speed.

[0060] As Figure 6 is a schematic diagram of a 4-stage flow channel. After the compressed air flow enters from the first-stage flow channel 311, it passes through the second, third, and fourth-stage flow channels 312, 313, and 314, and is ejected to act on the corresponding driving recess 11, and finally the body is output through the exhaust flow channel 310; Figure 5 is a schematic diagram of a 5-stage intake air flow channel, and the working process is the same as Figure 6 The schematic is similar. As Figure 6 , the secondary flow channel 300 includes a return channel and a communicating stroke channel, such as Figure 6 the return channel 3131 and the communicating stroke channel 3132 in the third-stage flow channel in

[0061] Please refer to Figure 2 , the gas power device further includes a shaft 2. The outer ring 1 and the core body 3 are coaxially arranged on the shaft 2. The shaft 2 is provided with intake and exhaust shaft channels 21 and 210 that are respectively connected to the intake channel 31 and the exhaust channel 310 of the core body 3. The intake and exhaust shaft channels in the shaft form an inlet and an outlet, and the intake and exhaust shaft channels are non-communicating structures. The outer ring 1 is cooperated with the shaft 2 through side plates 41 and 42 to form a closed space. The core body 3 is arranged in the closed space and is fixedly connected to the shaft 2. In this solution, the core body 3 is provided with at least 2 stages of flow channels, and each stage of the flow channel is connected to the corresponding driving recess of the outer ring, and finally the air flow is discharged through the exhaust flow channel.

[0062] Please refer to Figure 2 , in this solution, the core body 3 can be formed by the cooperation of a left core body and a right core body. The intake channel 31 and the exhaust channel 310 are provided on the mating surface of the left and right core bodies. The core body 3 can also be integrally cast.

[0063] Please refer to Figure 2 and Figure 5 . In this embodiment, it is a first-stage drive structure. One air channel is circumferentially arranged on the core body 3 to form a first-stage drive structure. The air channel is also called an independent work unit. An intake channel 31, a nozzle 301, at least two drive recesses 11, at least one secondary impact channel 300, a discharge port 302, and an exhaust channel 310 on the core body 3 and the outer ring 1 form an independent work unit. The gas power device includes at least one independent work unit. In the independent work unit, the intake channel 31, the nozzle 301, the drive recess 11, the secondary impact channel 300, the discharge port 302, and the exhaust channel 310 constitute an air flow path.

[0064] Please refer to Figure 2 and Figure 5 or Figure 6 . In this solution, there are more than two drive recesses 11 provided on the inner ring surface of the outer ring 1. Each drive recess has a contour bottom surface 111 and a drive surface 112. The contour line of the contour bottom surface 111 can be a common arc line or a spiral line. When the contour line of the contour bottom surface is a logarithmic spiral line, its pole is set on the axis. Each drive recess 11 communicates with the adjacent stage channel at the same time so that the air flow entering from the previous stage channel is output by the next stage channel.

[0065] In this solution, the intake channel of the core body 3, that is, the first-stage channel, can have a common arc line or a spiral line for its orientation. The strokes of each secondary impact channel, that is, the Nth-stage channel, can also have a common arc line or a spiral line for their orientation.

[0066] As Figure 5 and Figure 6 . In this solution, an intake channel 31 is provided on the core body 3, and its orientation is a logarithmic spiral line extending from the middle to the outside. The strokes of the secondary impact channels 300 have a logarithmic spiral line for their orientation. The logarithmic spiral line orientation of the strokes of the secondary impact channels is substantially the same as the logarithmic spiral line orientation of the intake channel. The orientation of the intake channel of the core body 3 is a logarithmic spiral line extending from the middle to the outside. The pole of the logarithmic spiral line is set on the central axis of the core body. The logarithmic spiral line orientation angle is 15° - 45°. The smaller the angle, the longer the channel and the more the loss; the larger the angle, the smaller the tangential component force for driving the outer ring.

[0067] Please refer to Figure 2 and Figure 3 and Figure 4 . In this solution, the inlet and outlet air channels 21, 210 in the shaft 2 form an inlet and an outlet, and the inlet and outlet air channels are non-connected structures. The inlet and outlet of the shaft can be set at one end of the shaft or at both ends of the shaft. The intake air channel 21 communicates with the intake channel 31 of the core body. The outlet of the shaft extends axially to form an outlet air channel 210, and the outlet air channel communicates with the exhaust channel 310 of the core body.

[0068] The outer ring is drivingly connected to the winding wheel 51. The rotation of the outer ring does work to drive the rotation of the winding wheel 51. The rotation of the winding wheel 51 winds up the fishing net line of the fishing net 53, thereby realizing the netting action of the fishing net. Further, referring to Figure 2 as shown, in this embodiment, a plurality of assembly holes are provided on the circumferential side of the outer ring. Referring again to Figure 6 as shown, a bolt 60 passes through the assembly hole and is fixedly screwed to a rotating shaft 60. The rotating shaft 60 is connected to the rotor of the generator, realizing the driving connection between the outer ring and the rotor of the engine. Of course, in other embodiments, the driving connection between the outer ring and the rotor of the engine can also be realized through a gear transmission mechanism. For example, external teeth are provided on the outer ring to facilitate the output of kinetic energy through gear transmission; another example is that the outer ring has a belt groove to output kinetic energy through belt transmission; yet another example is that the outer ring has a mounting flange to facilitate the installation of a coupling to output kinetic energy; and so on.

[0069] Still further, referring to Figure 8 as shown, to increase the air intake volume of the air intake passage 21 of the shaft 2, an air flow collection assembly is further provided. The air flow collection assembly includes a collection port 71 and a wind guiding and pressurizing flow passage 72. One end of the wind guiding and pressurizing flow passage 72 is connected to the collection port 71, and the other end is connected to the air intake passage of the gas power device. The collection port 71 corresponds to the wind flow direction and collects the wind flow. The collected wind flow is guided to the air intake passage of the gas power device through the guidance of the wind guiding and pressurizing flow passage 72.

[0070] Further, the collection port 71 has a structure of a flared mouth. The large flared mouth of the collection port 71 corresponds to the wind flow direction, and its small flared mouth is connected to the wind guiding and pressurizing flow passage 72.

[0071] Of course, in other embodiments, if the fishing boat is in a region or period with weak wind, a pre-prepared high-pressure air source can also be used, such as canned compressed air flow as the wind source. The air outlet of the high-pressure air source is connected to the air intake passage of the gas power device, and the high-pressure air source directly enters the core body 3 to drive the rotation of the outer ring 1.

[0072] The gas power device involved in this application refers to a device that can convert air flow energy into mechanical rotation. In addition to the necessary outer ring, core body and their corresponding concave structure or flow passage structure design, other components can also be included additionally; for example, a housing and a sealing structure for providing external protection can be included additionally, and another example is that a coupling for providing torque transmission can be included additionally. The materials of the core body and the outer ring are made of hard materials, not limited to metals, metal alloys, plastics, composite materials. The processing methods of the concave structure or flow passage structure of the core body and the outer ring can be realized by all known production means, including but not limited to die casting, forging, extrusion, 3D printing, and so on.

[0073] Figure 2 and Figure 5It should be noted that although the intake channel 31, exhaust channel 310 of the core body, intake shaft channel 21, and outlet shaft channel 210 do not correspond according to the drawing rules, for the sake of vivid illustration, Figure 2 the intake channel and exhaust channel of the core body herein refer to the intake channel and exhaust channel. In Embodiment 2, Figure 9 and Figure 12 a schematic diagram similar to this.

[0074] Embodiment 2

[0075] This embodiment provides a power device driven by wind power. Referring to Figure 13 as shown, specifically, it is a drone device 8, and the action execution mechanism is a propeller mechanism, including a propeller 81 and a rotating shaft 82 that drives the propeller 81 to rotate. The gas power device is arranged inside the drone device 8, such as Figure 13 the gas power device 801 in. A collection port for collecting air flow is provided at the front end of the drone device 8, and the air flow collected by the collection port flows through the air guiding and pressurizing flow channel 83 and is guided to the intake channel of the gas power device 801.

[0076] Specifically, in this embodiment, the gas power device 801 is substantially the same as the gas power device in Embodiment 1, and the difference lies in: Please refer to Figures 9 to 12 . The gas power device includes 2 independent working units to form a two-stage drive structure, that is, 2 air channels are arranged circumferentially on the core body 3. Each air channel includes an intake channel 31 with more than 1 stage and a secondary impulse flow channel 300 and is arranged circumferentially along the core body 3 and an exhaust flow channel. The gas power device includes an outer ring 1, and a plurality of driving recesses 11 are provided on the inner circumferential surface of its inner ring; a core body 3, which is coaxially arranged inside the outer ring 1 and can rotate relative to the outer ring. The outer circumferential surface of the core body is provided with 2 groups of nozzles, exhaust ports, and at least one secondary impulse flow channel is provided between each group of nozzles and exhaust ports; 2 intake channels 31, 32 are provided on the core body, which correspondingly communicate with the nozzles; and 2 exhaust channels 310, 320, which correspondingly communicate with the exhaust ports; two air flows enter from the 2 intake channels of the core body respectively, and are ejected step by step through the nozzles and the secondary impulse flow channels 300 of the core body 3, acting on the corresponding driving recesses 11 on the circumference of the outer ring, generating thrust on these driving recesses to push the outer ring 1 to rotate and do work, realizing power output. Finally, the air flow is discharged through the exhaust port of the core body through the exhaust channel. The above-mentioned one intake channel, one nozzle, the corresponding number of driving recesses, and the corresponding secondary impulse flow channel, exhaust port, and one exhaust channel form an independent working unit.

[0077] The gas power device further includes a shaft 2. The outer ring 1 and the core 3 are coaxially arranged on the shaft. The shaft 2 is provided with intake shaft channels 21, 22 and exhaust shaft channels 210, 220 which are respectively communicated with the intake channels 31, 32 and the exhaust channels 310, 320 of the core. The shaft 2 is provided with two intake ports and two exhaust ports corresponding to the air channels; the compressed air flow enters from the two intake ports of the shaft 2, sprays out through the intake channels of the core 3 and acts on the driving recess 11 of the outer ring 1, generating a thrust to drive the outer ring 1 to rotate and do work. Finally, the compressed air flow returns to the corresponding exhaust ports through the exhaust channels of the core 3, realizing continuous output of power.

[0078] The air flow collected by the collection port is guided through the air guiding and pressurizing flow channel 83 to the intake channel of the gas power device, thereby driving the outer ring 1 to rotate. The outer ring 1 is drivingly connected to the rotating shaft 82, thereby driving the rotating shaft 82 to rotate.

[0079] Further, in this embodiment, the driving structure of the gas power device 801 serves as an auxiliary driving mechanism of the UAV device. The main driving mechanism is an electric driving mechanism, that is, conventionally, a storage battery is used as an energy source to drive the motor to rotate, and the motor drives the propeller 81 to rotate through the rotating shaft 82; this main driving mechanism is a conventional existing structure and will not be described in detail. The driving structure of the gas power device 801 serves as an auxiliary driving mechanism of the UAV device. When the UAV device is flying, the air flow enters the gas power device 801 through the collection port, driving the operation of the gas power device 801, and the gas power device 801 provides auxiliary power to the rotating shaft 82. Adding this auxiliary driving mechanism can convert the resistance on the front of the UAV device into a power source, effectively reducing the energy consumption of the UAV device.

[0080] In this embodiment, the gas power device is applied to the UAV device as an example of an auxiliary driving mechanism of the UAV device. Of course, in other embodiments, the gas power device can also be arranged on devices such as high-speed flying vehicles and high-speed rails, converting the front resistance into auxiliary power or backup energy.

[0081] Embodiment III

[0082] The power device driven by wind provided in this embodiment is specifically a ventilation device for an underground passage, including a ventilation fan and a driving mechanism. The ventilation fan serves as an action execution mechanism, and the driving mechanism includes a gas power device. The structure of the gas power device is the same as that of the gas power device in Embodiment I. The outer ring of the gas power device is drivingly connected to the ventilation fan to drive the ventilation fan to rotate and realize ventilation.

[0083] Further, for the ventilation system of the underground passage set along the railway, the air intake passage of the gas power device is arranged on both sides of the track. When the high-speed train passes by at high speed, the high-speed air flow formed flows into the core of the gas power device from the air intake passage, and then drives the outer ring to rotate, realizing the rotation of the ventilation fan, and can effectively utilize the air flow generated by the high-speed movement of the high-speed train.

[0084] Of course, this power device is not limited to the ventilation device, and can also be other power devices, which will not be listed one by one here.

[0085] Embodiment 4

[0086] The power device driven by wind provided in this embodiment is specifically a mixer, including a mixing mechanism and a driving mechanism. The mixing mechanism of this mixer serves as the action execution mechanism. The driving mechanism includes a gas power device, and the structure of this gas power device is the same as that of the gas power device in Embodiment 1. The outer ring 1 of the gas power device is connected to the mixing shaft of the mixing mechanism to drive the mixing shaft to rotate, and then mixing is carried out.

[0087] In this power device, it is necessary to introduce the air flow into the air intake passage, and it is preferably introduced into the air intake passage after wind power boosting. All known technologies can be used to achieve this, such as a wind-guiding and boosting flow channel designed by fluid mechanics (realizing wind power boosting at the outlet), such as the wind-guiding and boosting flow channel 72 in Embodiment 1 and the wind-guiding and boosting flow channel 83 in Embodiment 2, turbochargers, and so on.

[0088] Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4 are respectively illustrated by different power devices, but are not limited to the above structures. It can also be a power device for action execution mechanisms such as a conveying mechanism, a powder grinding mechanism, etc., as long as it can replace the original driving mechanism of the gas power device in this case.

[0089] Through the power device driven by wind provided by the above embodiments, the gas power device replaces the existing power device powered by electricity or fuel. The multi-stage flow channels are arranged in the core of the gas power device, that is, the air intake passage serves as the first-stage flow channel, and each secondary impact flow channel serves as the second, third, fourth... stage flow channels. The air flow acts on the driving recess on the outer ring from the first-stage flow channel. The driving recess is communicated with the second-stage flow channel, and then returns to the second-stage flow channel and then acts on another driving recess on the outer ring, and so on, until the air flow is discharged from the exhaust passage. The whole process is carried out in the forward direction along the rotation direction of the outer ring, with large torque, high transmission efficiency, high air flow utilization rate, and the output torque further increases with the increase of the rotational speed.

[0090] Meanwhile, the flow channels arranged circumferentially on the core effectively reduce the volume of the overall device. The more the intake air flow channels are arranged on the core, the lower the overall weight is, and the output speed and efficiency of the device are further improved. It has the characteristics of high air flow utilization rate, large torque, high rotational speed, and high transmission efficiency. This power device is driven by wind power and does not require a structure driven by power or fuel. To a certain extent, it can replace or assist power devices driven by power or fuel, realize the utilization of clean energy, and lay a foundation for the future utilization of clean energy.

[0091] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all such changes are within the protection scope of the present invention.
