Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described below in combination with the embodiments.

The power prediction and monitoring device also includes a mounting ring 5, a rotation speed monitoring component and a flow blocking and speed increasing component. The mounting ring 5 is movably sleeved on the opposite side of the windward surface of the blade mounting seat 1, and the rotation speed monitoring component is arranged on the mounting ring 5 and connected to the blade mounting seat 1, and is used to detect the rotation speed of the blade mounting seat 1. The flow blocking and speed increasing component is arranged between the mounting ring 5 and the power generation blade 2, and is used to increase the impact of the airflow on the power generation blade 2;

[0032] The speed monitoring component includes a mounting frame 7, a protective shell 20, a driving wheel 21, a driven wheel 22 and a detection execution structure. The mounting frame 7 is arranged on the mounting ring 5, the driving wheel 21 and the blade mounting seat 1 are coaxially connected, the protective shell 20 is arranged on the mounting ring 5 and the mounting frame 7 is located on the inner side of the protective shell 20, the driven wheel 22 is movably arranged in the protective shell 20 and meshed with the driving wheel 21, and the detection execution structure is arranged on the mounting ring 5 and connected to the driven wheel 22, and is used to detect the speed of the blade mounting seat 1.

[0033] In a specific case of this embodiment, the detection execution structure includes a differential 23, a connecting shaft 24, a detection disk 27, a detection box and a detection piece.

The conductive ring 32 is arranged in the movable seat 29. The resistance rod 33 is arranged on the detection disk 27 and is parallel to the position of the guide rail 30. The conductive ring 32 is slidably sleeved on the outer wall of the resistance rod 33.

[0035] It should be noted that the present embodiment is not limited to the above-mentioned conductive ring 32 and resistor bar to detect the position of the movable seat 29 in the guide rail 30, and can also be replaced by an infrared distance sensor or a laser distance sensor, which are not listed here one by one.

[0036] In actual application, by installing the blade mounting seat 1 and the protective shell 20 on the mounting base of the wind power generation, when the air flow passes through the power generation blade 2 so that the power generation blade 2 rotates and generates electricity, the rotation of the blade mounting seat 1 can drive the driving wheel 21 to rotate. Under the meshing action between the driving wheel 21 and the driven wheel 22, the driven wheel 22 and the connecting shaft 24 can be driven to rotate, and then the detection disk 27 can be driven to rotate. Under the action of centrifugal force, the movable seat 29 can be moved along the guide rail 30, so that the conductive ring 32 and the resistance rod 33 are in contact at different positions according to the rotation speed of the detection disk 27, and then the rotation speed of the power generation blade 2 is obtained through the data processing box 19, and the power generation power of the power generation blade 2 is indirectly monitored and predicted. In the process of the movable seat 29 moving along the guide rail 30, it can drive the flow blocking and speed increasing component to work synchronously, so as to change the rotation speed of the power generation blade 2 according to the air flow speed and improve the power generation power by adaptively adjusting the impact force of the air flow on the power generation blade 2.

[0037] See also Figure 1 , Figure 2 , Figure 7 as well as Figure 8As another preferred embodiment of the present application, the detection execution structure also includes a kinetic energy supply member, which is arranged on the detection disk 27 and opposite to the detection member. The kinetic energy supply member connects the moving seat 29 and the flow blocking and speed increasing component. When the moving seat 29 moves, the kinetic energy supply member is controlled to work and provide power to the flow blocking and speed increasing component.

[0038] In this exemplary embodiment, the kinetic energy supply part includes a hollow tube 28 and a piston rod 31. The hollow tube 28 is arranged on the detection disk 27. The hollow tube 28 and the movable seat 29 are arranged relative to each other. The hollow tube 28 is connected to the flow blocking and speed increasing assembly through the detection box. The piston rod 31 is movably arranged in the hollow tube 28 and the two are elastically connected. The piston rod 31 is connected to the movable seat 29.

[0039] In addition, the detection box body includes a follower box 25 and a connecting base 26, the connecting base 26 is arranged on the mounting frame 7, a second cavity 35 is formed on the connecting base 26, the follower box 25 is movably arranged on the connecting base 26, a first cavity 34 connected to the second cavity 35 is formed on the follower box 25, the second cavity 35 is connected to the flow blocking and speed increasing component, and the flow blocking and speed increasing component obtains power when receiving or releasing the airflow output from the second cavity 35.

[0040] In the process of the detection disk 27 rotating and utilizing the centrifugal force to move the movable seat 29 along the guide rail 30, the piston rod 31 can be driven to move along the hollow tube 28, so that the gas in the No. 2 cavity 35 is drawn into the hollow tube 28 along the No. 1 cavity 34. When the air pressure value in the No. 2 cavity 35 changes, the flow-blocking and speed-increasing component can be controlled to operate, so that when the air passing through the power generation blades 2 is in a low-speed flow state, the contact strength between the power generation blades 2 and the airflow can be increased, thereby indirectly improving the power generation power.

[0041] See also Figure 1-Figure 8 As another preferred embodiment of the present application, the baffle speed increasing assembly includes a sleeve 4, a plurality of connecting rods 12, a baffle blade 3 and an angle adjustment structure. The airflow force side of each power generation blade 2 is hinged with a baffle blade 3, and a drainage gap is arranged between the baffle blade 3 and the power generation blade 2. The sleeve 4 is sleeved on the outer wall of the blade mounting seat 1, and a movable ring 6 is movably arranged on the mounting ring 5. The movable ring 6 is connected to the sleeve 4 through a plurality of connecting rods 12. Each of the baffle blades 3 is connected to the sleeve 4 through the angle adjustment structure. The angle adjustment structure is connected to the second cavity 35, and the angle adjustment structure adjusts the angle between the power generation blade 2 and the baffle blade 3 when working.

[0042] In this exemplary embodiment, the angle adjustment structure includes a driving gear 9, a driving cylinder 11, a guide seat 10 and a rack 8. The driving gear 9 is movably arranged on the power generation blade 2 and is coaxially connected to the baffle blade 3. The guide seat 10 is arranged on the sleeve 4. The rack 8 is movably arranged on the guide seat 10 and the two are elastically connected. The rack 8 is meshed with the driving gear 9. The driving cylinder 11 is arranged on the sleeve 4 and its movable end is connected to the rack 8. The driving cylinder 11 is connected to the second cavity 35.

[0043] It should be noted that the present embodiment is not limited to the above-mentioned cylinder to adjust the position of the rack 8, and a linear motor or an electric cylinder may be used instead, which are not listed here one by one.

[0044] When the detection disk 27 rotates so that the movable seat 29 moves along the guide rail 30, it can drive the piston rod 31 to move along the hollow tube 28 and draw the air in the cylinder into the hollow tube 28 along the No. 2 cavity 35 and the No. 1 cavity 34, which can drive the cylinder to contract, and then drive the rack 8 to move along the guide seat 10. Under the meshing action between the rack 8 and the gear, the gear and the baffle blade 3 are driven to rotate a certain angle. The rotation angle depends on the displacement generated by the movable seat 29 along the guide rail 30, that is, the rotation speed of the power generation blade 2 affects the angle between the baffle blade 3 and the power generation blade 2, thereby realizing the adjustment of the angle between the baffle blade 3 and the power generation blade 2 in the chassis, so that the passing airflow is gathered between the baffle blade 3 and the power generation blade 2 to increase the rotation speed of the power generation blade 2 and the blade mounting seat 1, thereby realizing the improvement of the wind power generation intensity when the air flow speed is too slow.

[0045] See also Figure 1 , Figure 2 as well as Figure 4 As another preferred embodiment of the present application, the power prediction monitoring device also includes a rain monitoring structure, which is arranged on the protective shell 20 and is used to detect rainy weather and rain precipitation.

[0046] In this exemplary embodiment, the rainwater monitoring structure includes a water collecting tank 13, a speed measuring device 14, a rotor 15, a water skiing slope 16, a water inlet 17 and a drain 18. The water collecting tank 13 is arranged on the surface of the protective shell 20. At least one measuring cavity is formed in the water collecting tank 13. The rotor 15 is movably arranged in the measuring cavity. The water inlet 17 and the drain 18 are arranged on the water collecting tank 13 and are connected to the measuring cavity. The speed measuring device 14 is arranged on the water collecting tank 13 and is coaxially connected to the rotor 15. The speed measuring device 14 is electrically connected to the data processing box 19. The water skiing slope 16 is arranged on the top of the protective shell 20 and is connected to the water inlet 17.

[0047] In rainy weather, rainwater can fall on the top of the water collecting tank 13 and flow into the water inlet 17 along the water skiing slope 16. The rainwater enters the measuring cavity along the water inlet 17 and is finally discharged from the drain outlet 18. During this process, the rainwater can contact and collide with the blades of the rotor 15, driving the rotor 15 to rotate. The greater the precipitation per unit time, the faster the rotation speed of the rotor 15. The rotation speed of the rotor 15 can be monitored in real time through the rotation speed meter 14, so that the rotation speed of the rotor 15 is fed back to the data processing box 19 and finally sent to the remote monitoring terminal of the monitoring personnel, so as to facilitate the monitoring personnel to understand the precipitation conditions around the wind power station and predict the power generation of wind power in real time.

[0048] How this application works:

[0049] By installing the blade mounting seat 1 and the protective housing 20 on the mounting base of the wind power generation, when the air flow passes through the power generation blade 2 so that the power generation blade 2 rotates and generates electricity, the rotation of the blade mounting seat 1 can drive the driving wheel 21 to rotate. Under the meshing action between the driving wheel 21 and the driven wheel 22, the driven wheel 22 and the connecting shaft 24 can be driven to rotate, thereby driving the detection disk 27 to rotate, and then under the action of centrifugal force, the movable seat 29 can be moved along the guide rail 30, so that the conductive ring 32 and the resistance rod 33 are contacted at different positions according to the rotation speed of the detection disk 27, and then the rotation speed of the power generation blade 2 is obtained through the data processing box 19, and the power generation power of the power generation blade 2 is indirectly monitored and predicted. When the detection disk 27 rotates, the movable seat 29 moves along the guide rail 3 When the gear 31 moves along the guide rail 30, the piston rod 31 can be driven to move along the hollow tube 28 and the air in the cylinder can be drawn into the hollow tube 28 along the second cavity 35 and the first cavity 34, which can drive the cylinder to contract, thereby driving the rack 8 to move along the guide seat 10. Under the meshing action between the rack 8 and the gear, the gear and the baffle blade 3 are driven to rotate a certain angle. The rotation angle depends on the displacement of the moving seat 29 along the guide rail 30, that is, the rotation speed of the power generation blade 2 affects the angle between the baffle blade 3 and the power generation blade 2, thereby realizing the adjustment of the angle between the baffle blade 3 and the power generation blade 2 in the chassis, facilitating the passing airflow to gather between the baffle blade 3 and the power generation blade 2 to increase the rotation speed of the power generation blade 2 and the blade mounting seat 1, thereby realizing the improvement of the wind power generation intensity when the air flow speed is too slow. In rainy weather, rainwater can fall on the top of the water collecting tank 13 and flow into the water inlet 17 along the water skiing slope 16. The rainwater enters the measuring cavity along the water inlet 17 and is finally discharged from the drain outlet 18. During this process, the rainwater can contact and collide with the blades of the rotor 15, driving the rotor 15 to rotate. The greater the precipitation per unit time, the faster the rotation speed of the rotor 15. The rotation speed of the rotor 15 can be monitored in real time through the rotation speed meter 14, so that the rotation speed of the rotor 15 is fed back to the data processing box 19 and finally sent to the remote monitoring terminal of the monitoring personnel, so as to facilitate the monitoring personnel to understand the precipitation conditions around the wind power station and predict the power generation of wind power in real time.
