Referring to fig. 1, an embodiment of the present invention provides a wind power generation simulation experiment apparatus, including: a frame 10, a turntable 20, and a plurality of paddles 30.
The frame 10 is adapted to carry a turntable 20, and the turntable 20 is controllably rotatably arranged on the frame 10 about a first rotation axis. The plurality of blades 30 are arranged on the turntable 20 and are distributed at intervals around the first rotation axis of the turntable 20, and each blade 30 is provided with an installation position for installing a wind power generation supporting facility, so that the turntable 20 can drive the blades 30 to rotate around the first axis, and the running condition of the wind power generator set can be simulated. Further, each blade 30 is rotatable relative to the turntable 20 about a second axis of rotation intersecting the first axis of rotation, such that the angle of the blade 30 can be adjusted by rotation of the blade 30 about the second axis of rotation, thereby simulating the pitching process of the wind park.
In the actual use process, the blades 30 are provided with wind power generation supporting facilities of a wind power generator set. The rotating disc 20 drives each blade 30 to rotate around the first axis to simulate the operation condition of the wind generating set, so that the blades 30 can bear external resistance from air flow when the rotating disc 20 rotates, the working condition of wind power generation supporting facilities on the blades 30 is simulated, and the working condition of the wind power generation supporting facilities is further tested. Furthermore, in order to detect the working conditions of the wind power generation supporting facility in different wind directions, the angle of the blade 30 is adjusted by rotating the blade 30, so that the wind power generation supporting facility can be subjected to airflow resistance in different directions, and the actual working state of the wind power generation supporting facility is further simulated.
According to the wind power generation simulation experiment device, the turntable 20 drives the blades 30 to rotate around the first axis for simulating the running condition of the wind generating set, and the rotation of the blades 30 around the second rotation axis can adjust the angle of the blades 30 for simulating the pitch changing process of the wind generating set. Through the simulation experiment device, the wind power generation supporting facilities of the wind generating set can be tested without hanging up, and the debugging time and cost of the wind generating set are greatly reduced.
It should be noted that the second rotation axis does not refer to a rotation axis in a certain direction, each blade 30 has a second rotation axis in a predetermined direction, and the plurality of blades 30 have second rotation axes in multiple directions. For example, referring to FIG. 1, the rotational axes about which any of the three blades 30 of FIG. 1 rotate are all second rotational axes, and as such, the rotational axes of all three blades 30 are all second rotational axes.
In the embodiment of the utility model, the pitch variation process of the wind generating set in the actual use process is simulated more conveniently. Referring to fig. 2 to 4, the wind power generation simulation experiment apparatus further includes a variable pitch mechanism 40 disposed on the turntable 20, the variable pitch mechanism 40 includes a power source 41 and a transmission assembly 42 in transmission connection with the power source 41, the power source 41 is mounted on the turntable 20, and the transmission assembly 42 is in transmission connection between the power source 41 and the plurality of blades 30. That is, a plurality of blades 30 may be simultaneously driven to rotate together by the power source 41. Thus, when the angle of the blade 30 needs to be adjusted, the angle of each blade 30 does not need to be adjusted independently, and all the blades 30 can be adjusted together by starting the power source 41, so that the time for adjusting the blades 30 is greatly reduced. Further, even in the process that the blades 30 rotate along with the rotating disc 20, the angles of the blades 30 can be adjusted, so that the actual working process of the wind generating set is simulated more truly, and the actual use condition of the wind power generation supporting facilities is further simulated more truly. It should be noted that the transmission assembly 42 may be a conventional one-to-many transmission manner such as a gear set, a worm gear, and the like, and is not limited herein.
In some embodiments, the transmission assembly 42 includes a drive bevel gear 43 and a plurality of driven bevel gears 44, the drive bevel gear 43 is mounted at the driving end of the power source 41, and the drive bevel gear 43 is driven to rotate by the power source 41. A plurality of driven bevel gears 44 are provided in one-to-one correspondence with the plurality of paddles 30, and each driven bevel gear 44 is mounted to a corresponding one of the paddles 30 and engaged with the driving bevel gear 43. In this way, when the drive bevel gear 43 rotates, the plurality of driven bevel gears 44 also rotate together with the drive bevel gear 43, and the rotation of the drive bevel gear 43 is converted into simultaneous rotation of the plurality of blades 30 by the rotation of the plurality of driven bevel gears 44.
It is appreciated that in other embodiments, there may be a plurality of pitch mechanisms 40, a plurality of pitch mechanisms 40 corresponding to a plurality of blades 30, and each pitch mechanism 40 being in driving connection with a corresponding blade 30. Each pitch mechanism 40 includes a power source 41 and a drive assembly 42 drivingly connected to power source 41. Each blade 30 is driven by a power source 41 to drive a transmission assembly 42 to rotate the blade 30. Like this, also can satisfy the variable pitch demand of wind power generation simulation experiment device to a plurality of variable pitch mechanisms 40 can also be controlled alone to the angle of every paddle 30, satisfy different experimental needs.
Note that, instead of driving the rotation of the paddle 30 by the power source 41, the angle of the paddle 30 may be adjusted manually. In another embodiment of the present invention, refer to fig. 5 to 8. The wind power generation simulation experiment device comprises a plurality of positioning mechanisms 50 which are connected with a plurality of blades 30 in a one-to-one correspondence mode, and each positioning mechanism 50 can be connected with or separated from the rotating disc 20 in a controlled mode. When the positioning mechanism 50 is separated from the turntable 20, the positioning mechanism 50 rotates with the paddle 30 corresponding to the positioning mechanism 50; when the positioning mechanism 50 is coupled to the turntable 20, the positioning mechanism 50 prevents the paddle 30 from rotating relative to the turntable 20.
In an actual use process, if the angle of the paddle 30 needs to be adjusted, the rotation of the turntable 20 is stopped first, the paddle 30 needing to be adjusted is selected, the positioning mechanism 50 corresponding to the paddle 30 is separated from the turntable 20, then the paddle 30 is rotated until the paddle 30 rotates to a required position, and then the positioning mechanism 50 corresponding to the paddle 30 is connected with the turntable 20, so that the paddle 30 is fixed at the required position, and the angle adjustment of the paddle 30 is completed. The angle of the blade 30 is adjusted by the positioning mechanism 50, so that the wind power generation supporting facility on the blade 30 can be subjected to airflow resistance in different directions, and the actual working state of the wind power generation supporting facility is simulated. Compared with the method that the power source 41 is adopted to drive the blades 30, the positioning mechanism 50 is adopted to adjust the angle of the blades 30, so that the wind power generation simulation experiment device is simpler in structure and lower in cost.
In some embodiments, the positioning mechanism 50 includes a clamping block 52 and a positioning member 51, the clamping block 52 is connected to the blade 30 corresponding to the positioning mechanism 50 and has a positioning hole 53, and the turntable 20 is initially provided with a plurality of fixing holes 54. In the process that the blade 30 drives the clamping block 52 to rotate, the positioning holes 53 can sequentially correspond to the fixing holes 54, and the positioning element 51 penetrates through the positioning holes 53 and one fixing hole 54 corresponding to the positioning hole 53.
In actual use, the paddle 30 to be rotated is selected, and the positioning member 51 is removed, so that the paddle 30 can rotate relative to the turntable 20. And continuing to rotate the blade 30, so that the blade 30 rotates to a certain required angle, the positioning member 51 is inserted into the positioning hole 53 and the fixing hole 54 corresponding to the angle, and the blade 30 is fixed on the turntable 20, so that the angle adjustment of the blade 30 can be completed. Alternatively, the positioning member 51 is a conventional fastener such as a bolt, or the like.
In other embodiments, referring to fig. 7 and 8, the positioning mechanism 50 includes a plurality of positioning positions during rotation of the blades 30, each positioning position corresponding to a rotation angle of one blade 30. Each positioning position corresponds to a group of hole position groups. The clamping block 52 has a plurality of positioning holes 53, the turntable 20 has a plurality of fixing holes 54 corresponding to the plurality of positioning holes 53 one by one, and each corresponding one of the positioning holes 53 and one of the fixing holes 54 constitute a group of hole groups. When the positioning mechanism 50 rotates to one of the positioning positions, one positioning hole 53 and one fixing hole 54 of the corresponding hole group are aligned, and the positioning member 51 is inserted through the aligned fixing hole 54 and positioning hole 53.
In an actual use process, since the positioning hole 53 corresponds to the fixing holes 54, the distance between two adjacent fixing holes 54 must be greater than a fixed value due to a certain width of the fixing hole 54, and thus the angle corresponding to the fixing hole 54 must also be greater than a fixed angle, so that the angle adjustment of the blade 30 cannot achieve a more accurate value. And a plurality of hole groups are formed by the plurality of positioning holes 53 corresponding to the plurality of fixing holes 54, so that the plurality of fixing holes 54 do not interfere with each other, and thus, the corresponding fixing holes 54 and positioning holes 53 can be set for a rotation angle required by the blade 30, so that the angle adjustment of the blade 30 is more precise.
In an embodiment, the positioning mechanism 50 further includes a pressing plate 55 detachably connected to the clamping block 52, and when the positioning member 51 is inserted into the positioning hole 53, the pressing plate 55 covers the positioning hole 53. When the positioning member 51 is inserted into the positioning hole 53 and the fixing hole 54 corresponding to the angle, the positioning member 51 is engaged with the positioning hole 53 and the fixing hole 54 by the pressing plate 55.

In the embodiment of the present invention, a speed measuring encoder 13 is further sleeved on the driving shaft 11. The rotating speed of the driving shaft 11 is measured through the speed measuring encoder 13, so that the rotating speed of the rotating disc 20 is obtained, the rotating speed is transmitted to the outside through the speed measuring encoder 13, and the rotating speed is conveniently monitored by a detector.
