Description

TECHNICAL FIELD

[0001] The present application relates to wind power generation, in particular, relates to a wind collecting cover and a vertical windmill. BACKGROUND

[0002] In the process of generating electricity by the vertical windmill, due to the limited area of the wind blade, the air flow directly acting on the wind blade is less, resulting in low utilization rate of wind power. SUMMARY

[0003] One of the purposes of the present application is to provide a wind collecting cover for improving the utilization rate of wind power. The technical scheme is as follows:

[0004] A wind collecting cover is arranged outside the main body of a vertical windmill to collect wind for wind power generation; the wind collecting cover comprises a support and at least two wind guide plates arranged on the support;

[0005] The support is arranged outside the main body of the vertical windmill;

[0006] The wind guide plate is vertically arranged, the wind guide plate comprises a first end and a second end in the horizontal direction, and the first ends of two adjacent wind guide plates form an air inlet, and the second ends of two adjacent wind guide plates form an air outlet, the air outlet is arranged to face the main body of the windmill; the width of the air inlet is greater than the width of the air outlet, and the width is the size in the transverse direction.

[0007] In the above technical scheme, the width of the air inlet of the wind collecting cover is larger than the width of the air outlet, and the wind collecting cover can collect more air flow during the process of air flow flowing from the air inlet to the air outlet, so that more air flow flows out of the air outlet. The wind collecting cover provided by the present application can increase the amount of air flow participating in the power generation process, thereby improving the utilization rate of wind power.

[0008] Further, the number of wind guide plates is multiple, and the multiple wind guide plates are uniformly distributed in the circumferential direction on the support, each wind guide plate comprises a first side and a second side, the first side of each wind guide plate is arranged to face the second side of the adjacent wind guide plate, and the second end of each wind guide plate is provided with a flow guide plate, and the flow guide plates arranged on all the wind guide plates are inclined to the second side of the wind guide plate.

[0009] By arranging the flow guide plates, the inclination directions of the flow guide plates are the same, which can change the flow direction of the air flow, and further change the utilization efficiency of wind power.

[0010] Further, the wind guide plate and the flow guide plate are smoothly connected.

[0011] Further, the flow guide plate is a curved surface structure.

[0012] Furthermore, in the vertical direction, the two ends of the air guide plate are flush with the two ends of the flow guide plate.

[0013] Furthermore, the first ends of adjacent air guide plates are reinforced by cables or brackets; the second ends of adjacent air guide plates are connected by cables.

[0014] The connection between two adjacent air guide plates via cables makes the position of the air guide plates more stable and less likely to cause the blades to deform or change direction due to excessive wind force.

[0015] Furthermore, there are two wind guide plates, which are configured to rotate around the main body of the vertical wind turbine.

[0016] Furthermore, a driving device is fixedly mounted on the bracket, and the air collecting hood also includes a ring-shaped structural component;

[0017] The annular structural member includes an annular rack disposed on its inner or outer side, and the output shaft of the drive device is connected to a gear, which meshes with the annular rack;

[0018] The air guide plate is fixedly connected to the annular structural component.

[0019] The second objective of this application is to provide a vertical wind turbine for improving the utilization rate of wind power. This is achieved using the following technical solution:

[0020] A vertical wind turbine includes a vertical wind turbine body and a wind collection shroud (as described above) disposed on five parts of the exterior of the vertical wind turbine body. The vertical wind turbine body is mounted on a support frame.

[0021] The vehicle body includes a main shaft, a support rod with one end fixedly connected to the main shaft and the other end rotatably connected to a fan blade shaft, and a fan blade fixedly connected to the fan blade shaft, wherein the fan blade shaft is vertically arranged;

[0022] The fan blades are configured such that, when acted upon by wind, the fan blades rotate synchronously with the main shaft around the axis of the main shaft, and each fan blade rotates on its own axis around the fan blade axis.

[0023] The vertical wind turbine provided by the above technical solution includes the wind collection shroud provided in this application, which can...

[0024] It can improve the utilization rate of wind power. In addition, since the blades rotate on their own axis while rotating around the main axis, the angle between the blades and the wind direction can be adjusted while the blades are revolving around the main axis. On the one hand, the airflow can drive the blades to rotate around the main axis more efficiently, and on the other hand, the airflow can reduce the obstruction of the blades to the rotation of the blades around the main axis.

[0025] 5. Further, the vertical wind turbine body also includes a transmission assembly, the transmission assembly comprising:

[0026] The first bevel gear is located on the outside of the main shaft;

[0027] A connecting rod rotatably connected to the support rod and horizontally arranged, the connecting rod being able to rotate about its own axis;

[0028] A second bevel gear and a third bevel gear are disposed at the first end of the connecting rod, wherein the second bevel gear meshes with the first bevel gear;

[0029] And a fourth bevel gear fixedly connected to the fan blade shaft, the fourth bevel gear meshing with the third bevel gear, and the transmission ratio between the first bevel gear and the fourth bevel gear is 2.

[0030] By setting the transmission ratio between the first and fourth bevel gears to 2, the obstruction of airflow to the rotation of the blades around the main shaft can be minimized, thereby improving the efficiency of wind power utilization.

[0031] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0046] In the description of the present application, it should be noted that the directions or position relationships indicated by the terms “inner”, “outer” and the like are based on the directions or position relationships shown in the drawings, or the directions or position relationships in which the products of the present application are usually placed, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms “first”, “second” and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0047] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] The inventors of this application provide a vertical wind turbine, including a turbine body and a wind collection shroud. Wherein, as... Figures 1 to 6 As shown, the wind turbine body includes a main shaft 1100, blades 1310, a blade shaft 1320 fixedly connected to the blades 1310, and a support rod 1200 connecting the main shaft 1100 and the blade shaft 1320. The number of support rods 1200 is the same as the number of blades 1310; the blade shaft 1320 is rotatably mounted on the support rods 1200. Preferably, the blade shaft 1320 is vertically arranged, and the support rods 1200 are horizontally arranged. After the airflow acts on the surface of the blades 1310, the blades 1310, the support rods 1200, and the main shaft 1100 rotate together around the axis of the main shaft 1100. A power generation device is connected to the main shaft 1100, and the rotation of the main shaft 1100 causes the power generation device to generate electricity.

[0049] During the revolution of the fan blade 1310 around the axis of the main shaft 1100, such as Figure 6 As shown in the diagram, the arrows indicate the wind direction. If the first blade 1311 does not rotate around the axis of the blade shaft 1320 during its revolution to the position of the second blade 1312, the torque generated by the wind force acting on the first blade 1311 during its revolution will gradually decrease and then reverse. Furthermore, the forces acting on the first blade 1311 and the second blade 1312 will be equal in magnitude but opposite in direction, severely impacting power generation efficiency. Therefore, in order to achieve simultaneous rotation of the blade 1310 and its axis of rotation around the main shaft 1100, and to adaptively change the angle between the blade 1310 and the wind direction (i.e.,...), a new method is needed. Figure 6 The α and β angles shown in the figure are used to ensure that the forces acting on the blades 1310 at different positions are all used to drive the rotation of the main shaft 1100, thereby reducing the mutual cancellation between the forces acting on the blades 1310 at different positions. This is to avoid hindering the rotation of the blades 1310 around the main shaft 1100 and affecting the power generation efficiency. The windmill provided in this application also includes a transmission assembly, which is used to make the blades 1310 rotate simultaneously while rotating around the axis of the main shaft 1100, so as to change the angle between the surface of the blades 1310 and the wind direction.

[0050] In one embodiment provided in this application, the transmission assembly includes a first transmission member, a second transmission member, and a third transmission member that are sequentially connected in a transmission manner, and the first transmission member and the second transmission member are connected in a transmission manner.

[0051] The relative motion between the second and third transmission components is rotation.

[0052] The third transmission component has a third axis, and the third transmission component is fixedly connected to the fan blade shaft 1320.

[0053] The axis coincides with the axis of the fan blade shaft 1320, which is rotatably mounted on the support rod 1200. The fifth second transmission component has a second axis, which is rotatably mounted on the support rod 1200 and can rotate around the second axis.

[0054] The axis rotates. During the rotation of the second transmission component around the second axis, it drives the third transmission component to rotate around the third axis, thereby adjusting the angle between the fan blade 1310 and the wind direction. The first transmission component has a first axis and can rotate independently around the first axis relative to the main shaft 1100; that is, while the main shaft 1100 rotates, the first transmission component can remain stationary relative to the ground. The first axis coincides with the axis of the main shaft 1100, meaning the first transmission component can rotate around the axis of the main shaft 1100. First transmission component...

[0055] During the transmission process with the second transmission component, the second transmission component rotates relative to the first transmission component around the first axis and rotates on its own axis around the second axis.

[0056] Since the windmill body contains multiple blades 1310, the third transmission component is correspondingly connected to the second...

[0057] The number of transmission components is also multiple, consistent with the number of fan blades 1310. The part of the first transmission component that connects to the second transmission component 5 is a ring structure, and the axis of this ring structure is the first axis.

[0058] This enables the second transmission component to rotate 360° around the main shaft 1100 on the annular structure.

[0059] During the rotation of the main shaft 1100, the support rod 1200, which is fixedly connected to the main shaft 1100, rotates around the axis of the main shaft 1100; the second transmission component, which is provided on the support rod 1200, also rotates around the axis of the main shaft 1100.

[0060] The rotation of the axis 1100, that is, the rotation of the second transmission member relative to the first axis around the first transmission member, is due to the transmission relationship between the first and second transmission members. The second transmission member also rotates around the second axis.

[0061] The line rotates; correspondingly, during the rotation of the second transmission component, the third transmission component is driven to rotate around the third axis. Since the axis of the fan blade shaft 1320 coincides with the third axis and the fan blade shaft 1320 is fixedly connected to the third transmission component, the fan blade shaft 1320 also rotates around its own axis. The angle between the fan blade 1310 and the wind direction changes during the rotation of the main shaft 1100.

[0062] In some optional embodiments of this application, the annular structure in the first transmission member may be the...

[0063] A conical friction wheel, or... Figure 5 The first bevel gear 1410 is shown. The second transmission component includes a connecting rod 1421, the axis of which is the second axis; a useful [transmission element] is provided at the first end of the connecting rod 1421.

[0064] A second conical friction wheel, or a second bevel gear 1422, is used to transmit power to the first transmission member, enabling the second transmission member to rotate around the second axis while rotating around the first axis. A third bevel gear 1423 is provided at the second end of the connecting rod 1421, and the third transmission member includes components that interact with the third bevel gear.

[0065] The fourth bevel gear 1430 meshing with 1423, or the second end of the connecting rod 1421 is provided with a first helical gear, and the third transmission component is provided with a second helical gear meshing with the first helical gear; so as to realize the second transmission component

[0066] During the horizontal rotation of the main shaft 1100, the third transmission component can rotate with the fan shaft 1320 around a vertical axis (i.e., the axis of the fan shaft 1320 or the third axis). Preferably, the number of teeth of both the first bevel gear 1410 and the fourth bevel gear 1430 is a multiple of 4. The above-mentioned...

[0067] The first bevel gear 1410 and the fourth bevel gear 1430, with their tooth numbers in relation to each other, enable the two opposing fan blades 13105 to be perpendicular to each other. During the rotation of the fan blade 1310, the included angle formed by the two adjacent fan blades 1310 varies between 45° and 135°.

[0068] Preferably, the transmission ratio between the first transmission member and the second transmission member is 2, that is, when the first transmission member is fixed, during the process of the main shaft 1100 rotating 180° around its own axis, the fan shaft 1320...

[0069] Rotating 90° around its own axis reduces the mutual cancellation of forces acting on the wind blades 1310 at different positions, thereby increasing the force driving the wind blades 1310 to rotate around the main shaft 1100 and improving power generation.

[0070] Efficiency maximizes power generation efficiency.

[0071] The above-mentioned scheme of reducing the mutual offset of the force borne by the wind blades 1310 at different positions realizes the principle of maximizing the power generation efficiency of the vertical power generation windmill as shown in Figure 6 The arrow in the figure indicates the direction of the airflow, i.e. the wind direction. After rotating 180°, the first wind blade 1311 rotates to the position of the second wind blade 1312, and the force acting on the first wind blade 1311 and the second wind blade 1312 will make the main shaft 1100 rotate in the opposite direction, and the mutual offset exists between them. Therefore, when the first wind blade 1311 rotates to the position of the second wind blade 1312, the first wind blade 1311 should rotate 90° around the axis of the wind blade shaft 1320, i.e. as shown in Figure 6 The surfaces of the first wind blade 1311 and the second wind blade 1312 should be perpendicular to each other, so as to ensure that the force acting on the surface of the second wind blade 1312 is minimized, and the force acting on the first wind blade 1311 and the force acting on the second wind blade 1312 offset each other, so as to reduce the resultant force of driving the first wind blade 1311 to rotate around the axis of the main shaft 1100, and maximize the power generation efficiency.

[0072] Therefore, when the wind blade 1310 rotates 180° around the axis of the main shaft 1100, the wind blade 1310 should rotate 90°. In this process, the relative rotation angle between the first transmission member and the second transmission member is 180°, and the rotation angle of the third transmission member around its own axis is 90°, i.e. the transmission ratio between the first transmission member and the third transmission member is 2, that is, in the process of the wind blade 1310 rotating one revolution around the main shaft 1100, the wind blade 1310 rotates half a revolution around the axis of the wind blade shaft 1320.

[0073] Since the wind direction may not be consistent every time, after the wind direction changes, the power generation efficiency of the windmill may be affected, therefore, the application also provides a first driving device connected with the transmission assembly, for driving the first transmission member in the transmission assembly to rotate, and further driving the third transmission member to rotate, so as to adjust the included angle between the wind blade 1310 and the wind direction, and improve the power generation efficiency of the vertical windmill. Since the plurality of third transmission members are connected to the same first transmission member through the second transmission member, in the process of the rotation of the first transmission member, all the third transmission members can be synchronously rotated, and the included angle between all the wind blades 1310 and the wind direction can be adjusted. The first driving device and the transmission assembly constitute an angle adjusting mechanism.

[0074] The angle adjusting mechanism provided by the application is used to rotate the wind blade 1310 around the wind blade shaft 1320 when the wind rises, and when the wind direction changes.

[0075] Now, the application will be described in detail with reference to the accompanying drawings. Figure 6The principle by which the angle adjustment mechanism provided in this application can improve power generation efficiency is explained. The direction indicated by the arrow in the figure is the wind direction. Figure 6 In this design, the length of the support rod 1200 is perpendicular to the wind direction. If the surface of the first blade 1311 is also perpendicular to the wind direction, the force exerted by the airflow on the blade 1310 is maximized, the distance from the line of action of the wind force to the axis of the main shaft 1100 is maximized (i.e., the lever arm is maximized), and correspondingly, the torque that causes the main shaft 1100 to rotate is also maximized, resulting in the highest power generation efficiency of the wind turbine. When the wind direction changes, when the length of the support rod 1200 is perpendicular to the wind direction, the surface of the blade 1310 on the support rod 1200 may not be perpendicular to the wind direction. Therefore, the angle adjustment mechanism provided in this application is needed to adjust the angle between the blade 1310 and the wind direction.

[0076] Based on the above, those skilled in the art should readily understand that the rotation of the transmission component in this application is automatically achieved through the transmission relationship between various structures during power generation. The wind-adjusting process in this application is as follows: the first driving device moves the transmission component, thereby causing the wind turbine shaft 1320, connected to the third connecting member in the transmission component, to rotate, thus changing the angle between the wind turbine blade 1310 and the wind direction. That is, during the operation of the angle adjustment mechanism, the first driving device is the driving member, and the third transmission member connected to the wind turbine shaft 1320 is the driven member. Although both the transmission component and the angle adjustment mechanism provided in this application are used to change the angle between the wind turbine blade 1310 and the wind direction, the transmission component continuously adjusts the angle between the wind direction and the wind turbine blade 1310 during power generation, while the angle adjustment mechanism requires manual activation to improve the power generation efficiency of the wind turbine after the wind direction changes.

[0077] In some optional embodiments, the first driving device includes a first driving assembly and a sleeve 3110. The sleeve 3110 is a tubular structure fitted around the outside of the main shaft 1100 and can rotate independently relative to the main shaft 1100. Specifically, a bearing can be provided between the sleeve 3110 and the main shaft 1100. The sleeve 3110 is fixedly connected to the first transmission component, and the axis of the sleeve 3110 coincides with the first axis. The first driving assembly is used to drive the sleeve 3110 to rotate around the axis of the main shaft 1100. Specifically, in some embodiments, such as... Figure 2 , Figure 4 and Figure 5As shown, the first driving assembly includes a motor 3210, and an output shaft of the motor 3210 is connected with a first sprocket 3220. The outer side of the sleeve 3110 is fixedly connected with a second sprocket 3120, and the rotation axis of the second sprocket 3120 coincides with the axis of the sleeve 3110. A chain 3300 is connected between the first sprocket 3220 and the second sprocket 3120 to achieve the transmission connection between the sleeve 3110 and the first driving assembly. In the above embodiment, the chain transmission is used to achieve the transmission between the first driving device and the transmission assembly. When the space around the first transmission member is sufficient, the gear transmission can also be used between the first driving device and the transmission assembly. That is, the output shaft of the motor 3210 is connected with a first gear, the outer side of the sleeve 3110 is fixedly connected with a second gear, and the first gear and the second gear are meshed with each other to achieve the transmission connection between the first driving device and the transmission assembly.

[0078] After the angle adjusting mechanism is used to adjust the included angle between the fan blade 1310 and the wind direction, the first transmission member should no longer rotate around the first axis. Therefore, in some embodiments, a locking device is further provided for locking the first driving device. By locking the first driving device, the sleeve 3110 can be prevented from rotating with the first transmission member. Specifically, in some embodiments as shown in Figure 2 As shown, the output shaft of the motor 3210 is connected with a brake disc 3211, and the locking device includes clamps 4100 arranged on both sides of the brake disc 3211. The clamps 4100 are connected with a second driving assembly. By the second driving assembly, the clamps 4100 on both sides of the brake disc 3211 are in contact with the brake disc 3211, which can prevent the motor 3210 from rotating and further prevent the sleeve 3110 from rotating with the first transmission member. In other embodiments, as shown in Figure 2 As shown, the locking device includes a third driving assembly 4200. The third driving assembly 4200 has an output shaft that can be extended and retracted. A third sprocket 4300 that can be matched with the chain 3300 or a third gear that can be meshed with the first gear or the second gear is fixedly arranged on the output shaft. After the output shaft is extended, the third sprocket 4300 cooperates with the chain 3300 to prevent the second sprocket 3120 from rotating. Or after the output shaft is extended, the third gear is meshed with the first gear or the second gear to prevent the second gear from rotating.

[0079] The wind collecting cover provided in the present application includes a support 2100 and air deflectors 2200 vertically arranged on the support 2100. As shown in Figure 7 As shown in Figure 10 In the horizontal direction, the air deflector 2200 includes a first end and a second end. The first ends of adjacent two air deflectors 2200 form air inlets, and the second ends of adjacent two air deflectors 2200 form air outlets. As shown in Figure 9As shown, the windmill body is arranged at the position where the air outlet is located, so that the airflow blown out of the air outlet can act on the wind blade 1310. Among them, the width of the air inlet should be greater than the width of the air outlet, that is, the distance between the first ends of the adjacent two air deflectors 2200 should be greater than the distance between the second ends, so as to realize the gathering effect on the airflow. In order to improve the stability of the air deflector 2200, in some embodiments, the first end of the air deflector 2200 is connected to the second end of the air deflector 2200 through the cable 2300.

[0080] In some embodiments, as Figure 8 As shown, the air deflector 2200 is provided with a flow guide plate 2210 at the second end, which is used to change the direction of the airflow, so that the airflow acts vertically on the wind blade 1310 as much as possible. The air deflector 2200 includes a first side and a second side, as Figure 7 And Figure 9 As shown, the first side of the air deflector 2200 is arranged towards the second side of the adjacent air deflector 2200; the flow guide plate 2210 is arranged obliquely towards the first side of the air deflector 2200. Exemplarily, the way to realize the oblique arrangement of the flow guide plate 2210 towards the first side of the air deflector 2200 can be to adopt the flow guide plate 2210 in the form of an arc-shaped structure; or to adopt the flow guide plate 2210 in the form of a planar plate structure, as long as the included angle between the flow guide plate 2210 and the first side of the air deflector 2200 is within the range of (90°, 180°).

[0081] Since the direction of the wind may not be consistent every time, in some embodiments, a plurality of air deflectors 2200 are arranged on the support 2100 to collect as much airflow as possible in various directions. Exemplarily, as Figure 7 And Figure 9 As shown, eight air deflectors 2200 are arranged on the support 2100, and the second end of each air deflector 2200 is provided with a flow guide plate 2210, which is inclined towards the first side of the flow guide plate 2210, that is, the flow guide plate 2210 is inclined towards the second side of the adjacent flow guide plate 2210. It should be noted that the flow guide plate 2210 can also be inclined towards the second side of the air deflector 2200, as long as the flow guide plates 2210 in the wind collector are inclined in the same direction.

[0082] In view of the fact that the direction of the wind may not be consistent every time, in the case where the number of air deflectors 2200 is small, a driving device can be arranged to make the air deflector 2200 rotate around the windmill body on the support 2100, so that the air deflector 2200 can collect airflow in various directions. Exemplarily, as Figure 10 And Figure 11As shown, in some embodiments, the second driving device 2500 is arranged on the support 2100, the second driving device 2500 is drivingly connected with the annular structure 2400, and the guide vane 2200 is fixedly arranged on the annular structure 2400. The outer side or the inner side of the annular structure 2400 is provided with a rack, the output shaft of the second driving device 2500 is connected with a fourth gear 2600, and through the meshing of the fourth gear 2600 and the rack, the guide vane 2200 can be driven by the second driving device 2500 to rotate around the main body of the windmill. In some embodiments, the support 2100 provided by the application is a frame structure.

[0083] In order to realize the automatic control of the first driving device and the second driving device 2500, the vertical power generation windmill provided by the application further comprises a control module, the control module is signal connected with the first driving device, the second driving device 2500 and the locking device, in addition, the vertical power generation windmill provided by the application further comprises a wind direction detection device and a wind blade inclination detector which are signal connected with the control module. The wind direction detection device is used for measuring the wind direction, and the existing wind direction collector or wind vane can be used; the wind blade inclination detector is used for detecting the normal direction of the surface of the wind blade. After the measurement results of the wind direction detection device and the wind blade inclination detector are fed back to the control module, the control module controls the first driving device to change the included angle between the wind blade 1310 and the wind direction, and then the control module sends a signal to the locking device to lock the driving device, so as to avoid the rotation of the first transmission member. After the control module receives the wind direction measured by the wind direction detection device, the control module sends a signal to the second driving device 2500 to drive the annular structure 2400 to rotate, so as to realize that the air inlet formed by the guide vane 2200 is opposite to the direction of the wind, thereby increasing the air inlet amount and enhancing the effect of the wind.

[0084] It should be noted that the features in the embodiments of the application can be combined with each other without conflict.

[0085] The above only describes the preferred embodiments of the application and is not used to limit the application. For those skilled in the art, the application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
