Example 2:
on the basis of the energy capturing device with energy capturing efficiency adjustment for bladeless wind power generation provided in embodiment 1, embodiment 2 provides an energy capturing method for bladeless wind power generation, the method comprising: the current wind speed is obtained, and the height of the energy capturing component 2 is adjusted according to the current wind speed. In a possible embodiment, the current wind speed can be obtained by the wind speed sensor 3 in the embodiment 1, after the current wind speed is obtained, the telescopic mechanism 4 is controlled to adjust the height of the energy capturing assembly 2 according to the current wind speed, and the height specific adjustment degree can be controlled by the encoder 429. The specific implementation structure of each component is described in detail in embodiment 1, and will not be described herein.
In this embodiment, the current wind speed and the height of the energy capturing assembly 2 each include at least three gear positions, for example, in one possible implementation, the current wind speed may be divided into three gear positions, a high gear wind speed, a middle gear wind speed, and a low gear wind speed; it should be noted that, the high-speed wind speed may be a high-speed wind speed critical value, for example, as long as the wind speed is greater than v1, the specific value of v1 is set in advance by a worker, and the set standard is that after the wind speed is considered to be exceeded, the high-speed wind speed critical value easily causes large vibration to the energy capturing component 2 at a normal height, and may cause damage to parts. Similarly, the low-gear wind speed is a low wind speed critical value v2, and the specific value of v2 is set in advance by a worker, and the set standard is that the vibration intensity of the energy capturing component 2 at a normal height is insufficient easily after the wind speed is considered to be lower, so that the energy conversion efficiency is lower, and the power generation efficiency is lower. The wind speed range between v1 and v2 is set to be the middle gear wind speed range, and the energy capturing component 2 with normal height can achieve ideal energy conversion efficiency under the wind speed of v1 and v2, and the problem of part damage is not easy to occur. For the height of the energy capturing component 2, three-gear height can be set according to the division of high-gear wind speed, middle-gear wind speed and low-gear wind speed: the high-grade height h1, the middle-grade height h2 and the low-grade height h3, wherein the middle-grade height h2 is the energy capturing component 2 with the normal height, which means that the energy capturing component 2 can achieve ideal energy conversion efficiency under the wind speed of the normal height and v1-v2, and the problem of part damage is not easy to occur; the standard set by the high-grade height h1 of the energy capturing component 2 is that the vibration intensity of the energy capturing component 2 can be increased through the high-grade height under the condition that the low wind speed v2 is considered, so that the power generation efficiency is improved; the standard set by the low-grade height h3 of the energy capturing component 2 is considered to be above the high wind speed v1, and the vibration intensity of the energy capturing component 2 can be reduced through the low-grade height, so that the safety of parts is ensured.
Specifically, as shown in fig. 16, at the time of actual use, three cases can be classified.
First case (step 100 in the figure): when the current wind speed is the wind speed in the middle gear, the height of the energy capturing assembly 2 is kept to the height of the middle gear through the telescopic mechanism 4. For example, if the current wind speed is within the range of v1-v2, the height of the energy capturing component 2 is kept at the middle gear height h2 by the telescopic mechanism 4, and it is required to be noted that the height of the energy capturing component 2 is initially the middle gear height h2, and the current wind speed is kept unchanged when the wind speed is within the range of v1-v2, and of course, if the height of the energy capturing component 2 is adjusted before, the height of the energy capturing component 2 is adjusted back to the middle gear height h2 after the wind speed is detected to be within the range of v1-v 2.
Second case (step 200 in the figure): when the current wind speed is the wind speed in the high gear, the height of the energy capturing assembly 2 is reduced to the height in the low gear through the telescopic mechanism 4. For example, when the current wind speed is above v1, the height of the energy capturing component 2 is reduced to the low-grade height h3 through the telescopic mechanism 4, and the vibration effect can be reduced after the height of the energy capturing component 2 is reduced, so that the safety of parts is ensured.
Third case (step 300 in the figure): when the current wind speed is the wind speed in the low gear, the height of the energy capturing assembly 2 is increased to the height of the high gear through the telescopic mechanism 4. For example, when the current wind speed is below v2, the height of the energy capturing component 2 is raised to the high-grade height h1 through the telescopic mechanism 4, and after the energy capturing component 2 is raised, the vibration effect can be increased, so that the power generation efficiency is improved.
It should be noted that the above situation is only an example, and in a more refined manner, the wind speed and the altitude can be divided into more levels, and the wind speed range of each level corresponds to the altitude of one level; when different wind speeds are met, different heights of the energy capturing component 2 can be adjusted, so that the safety of parts is ensured, and meanwhile, the power generation efficiency is maximized. It should be noted that, the correspondence of more levels may be understood as an extension of "high-grade", "medium-grade" and "low-grade", which may be basically divided into three grades, but not just in each of the high-grade, medium-grade and low-grade, but also into more grades.
In an alternative manner of this embodiment, the low gear, the medium gear and the high gear are provided with three-stage sub-gears under respective gear corresponding to specific different wind speeds, for example, the height h3 of the previous low gear corresponds to a wind speed v1 of the high gear or more; the height h2 of the mid gear corresponds to the wind speed v1-v2 of the mid gear; the height h1 of the high gear corresponds to a wind speed v2 of the low gear or less. In the present embodiment, these gears may also be subdivided: dividing the wind speed v1 above the high gear into three sub-gears: v1-v11, v11-v12, v12 above, wherein v12 is greater than v11 and greater than v1; dividing wind speeds v1-v2 of the middle gear into three sub-gears: v1-v10, v10-v20, v20-v2, wherein v1 is greater than v10 and v20 is greater than v2; dividing the wind speed v2 below the low gear into three sub-gears: v2-v21, v21-v22, v22 or less, wherein v2 is greater than v21 and greater than v22; the sub gears corresponding to the wind speed are also provided with sub gears corresponding to the heights, and the sub gears h31, h32 and h33 above v1-v11, v11-v12 and v12 can respectively correspond to the heights; v1-v10, v10-v20, v20-v2 may correspond to the height sub-gears h21, h22, h23, respectively; the height sub-gears h11, h12 and h13 can be respectively corresponding to the positions below v2-v21, v21-v22 and v22; where h31, h32, h33 are height of the fine tune around h3, h21, h22, h23 are height of the fine tune around h2, and h11, h12, h13 are height of the fine tune around h1 to ensure the most efficient power generation efficiency at each wind speed sub-gear. The low gear, the medium gear and the high gear can be set by leaving the factory, belong to a rough corresponding relation and can be suitable for most scenes; the sub-gears of the three gears can be established periodically due to the installation of equipment, the difference of the equipment, aging and the like, so that the power generation efficiency is long and high.
The establishment of the mapping relation between the three-level sub-gear and the wind speed under each gear specifically comprises the following steps:
Acquiring a current wind speed, and keeping the height of the energy capturing component 2 to the height of a corresponding gear through a telescopic mechanism 4 according to a low gear, a middle gear or a high gear corresponding to the current wind speed; for example, the current wind speed is above the wind speed v1 of the high gear, which keeps the height of the energy capturing assembly 2 at h3, and then the mapping relation of the sub gears is established through subsequent fine tuning.
Continuously monitoring the current wind speed, and entering a mapping relation establishment process between a wind speed sub-gear and a height sub-gear under the condition that the wind speed does not fall out of the current gear:
The height of the energy capturing component 2 is adjusted according to the preset fine adjustment distance, the generating capacity of the current generating device is continuously monitored, when the generating capacity reaches a peak value, whether the wind speed change amplitude in the preset time distance before and after the generating capacity peak value moment is smaller than a preset threshold value is confirmed, if so, a round of effective mapping relation is established, otherwise, invalid entering the next round of mapping relation establishment process is confirmed, and the invalid mapping relation can be directly discarded; and dividing three-level sub-gears in the current gear according to the height of the energy capturing component 2 corresponding to the wind speed at the peak moment of the generated energy. The explanation for this process is as follows: for example, when the current wind speed is above the high gear wind speed v1 and the height of the energy capturing component 2 is above the low gear height h3, the sub-gear mapping relation under the gear is to be established, then the height of the energy capturing component 2 is adjusted according to the preset fine adjustment interval under the current wind speed, that is, fine adjustment is performed near the height h3, during the fine adjustment, the wind speed needs to be kept within a range of sub-gears, the preset threshold value of the wind speed change amplitude can be set according to the range of the sub-gears, for example, the preset time distance before and after the wind speed change amplitude can be set according to the time of one round of adjustment, and after the time of one round of adjustment or longer, the wind speed change amplitude is smaller than the preset threshold value, that is, when the range of one sub-gear is not exceeded, the wind speed change amplitude reaches the peak value, that is, the high sub-gear height corresponding to the wind speed sub-gear can be considered; for example, the wind speed is kept within v1-v11 for a period of time, and when the altitude is trimmed from h3 to a certain altitude, the power generation amount reaches a peak value, and then the altitude is h31 corresponding to the v1-v11 sub-gear, and the value is recorded for subsequent use. Similarly, when the wind speed is in other sub-gears, the corresponding high sub-gear can be finely adjusted and confirmed through the scheme and recorded for use in a subsequent period of time, and the sub-gear mapping is re-established until the next periodical maintenance modification time comes. The established mapping may be as shown with reference to fig. 18.
In an alternative way of this embodiment, a precondition for adjusting the height of the energy capturing assembly 2 according to the wind speed may also be set: and setting a preset time length, and carrying out the height adjustment of the energy capturing assembly 2 when the wind speed duration time of the same gear is detected to exceed the preset time length. The preset time period is at least longer than the time period required by the energy capturing assembly 2 for adjusting the height by one round. The reason for this is to reduce the situation that the wind speed is shifted again when the wind speed gear change is detected to carry out the height adjustment, and the adjustment fails and needs to be repeatedly carried out again; after the preset time length is set, when the wind speed is maintained in the same gear for more than the preset time length, the high-speed gear can be considered to be highly regulated without gear change in a short time, so that the condition that the wind speed gear change is too fast, the regulation fails and the regulation needs to be repeated again is reduced.

On the basis of the energy capturing device and method for bladeless wind power generation with energy capturing efficiency adjustment provided in embodiment 1 and embodiment 2, this embodiment 2 provides an energy capturing system for bladeless wind power generation, as shown in fig. 17, the system includes: the wind speed acquisition module is used for acquiring wind speed of the wind turbine; the energy capturing device is provided with a telescopic mechanism 4 for adjusting the height of the energy capturing component 2; the wind speed acquisition module is used for acquiring the current wind speed and transmitting the current wind speed data to the control module; the control module is used for judging the height required by the energy capturing component 2 according to the current wind speed, and adjusting the telescopic mechanism 4 through the height adjusting module so that the height of the energy capturing component 2 is adjusted to correspond to the height required by the current wind speed.
In a specific embodiment, the control module, the wind speed acquisition module and the height adjustment module are all one, and the control module is respectively connected with the telescopic mechanism 4 of each energy capturing device so as to perform uniform height adjustment control on all the energy capturing devices; the wind speed acquisition module and the height adjustment module are arranged on one energy capturing device, and all the energy capturing devices are arranged according to a preset distance array.
In a specific embodiment, the wind speed acquisition module includes a wind speed sensor 3 and the altitude adjustment module includes an encoder 429. The current wind speed can be obtained through the wind speed sensor 3, after the current wind speed is obtained, the control module controls the servo motor 421 of the telescopic mechanism 4 to adjust the height of the energy capturing component 2 according to the current wind speed, and the highly specific adjustment degree can be controlled through the encoder 429.
For the energy capturing device, the energy capturing device of the first structure is the energy capturing device of embodiment 1, and the detailed description of the structure of the energy capturing device of the first structure in embodiment 1 is omitted herein, and the wind speed acquiring module and the height adjusting module are integrally arranged on one energy capturing device, which is the energy capturing device of the first structure and may be referred to as a full-version energy capturing device. The energy capturing device of the second structure can be called a simplified version energy capturing device, the simplified version energy capturing device is based on the complete version energy capturing device, the related arrangement of the wind speed sensor 3 and the encoder 429 is subtracted, and other structures are kept unchanged. Therefore, in a range, the wind speed in the current range and the height to be adjusted can be obtained by only adopting one complete plate energy capturing device to be connected with the control module, all other energy capturing devices can adopt simplified plate energy capturing devices, and the control module only needs to control the simplified plate energy capturing devices to be consistent with the complete plate energy capturing devices in adjustment when the height is adjusted. Such an arrangement may save costs and enable batch control. When the wind speed acquisition module of the full-version energy capturing device adopts the wind speed sensor 3, the full-version energy capturing device can be used separately from the energy capturing device, and the wind speed sensor 3 can be independently arranged at a static position near the device for detection.
In a specific embodiment, a timer module may be further provided, where a preset time length is built in the timer module, the timer module is connected to the control module or directly provided in the control module, and when the control module detects that the wind speed is shifted to a certain gear through the wind speed acquisition module, the timer module starts to count, and after the preset time length is reached, the timer is ended, and the control module starts to perform height adjustment. The preset time period is at least longer than the time period required by the energy capturing assembly 2 for adjusting the height by one round. The reason for this is to reduce the situation that the wind speed is shifted again when the wind speed gear change is detected to carry out the height adjustment, and the adjustment fails and needs to be repeatedly carried out again; according to the embodiment, after the preset time length is set through the timer module, when the wind speed is maintained at the same gear for more than the preset time length, the wind speed can be considered to be high, the gear change can not occur again in a short time, and the height adjustment is performed, so that the wind speed gear change is reduced too quickly, the adjustment failure is caused, and the adjustment needs to be repeated again.
In a specific embodiment, a wind speed height mapping module can be further arranged, and the wind speed height mapping module is connected with the control module or is directly arranged in the control module, and a comparison table is built in the wind speed height mapping module in advance, so that the wind speed corresponds to the height of the energy capturing component 2; referring to fig. 18, for example, when the wind speed is divided into v1 or higher, v1-v2 or lower, and v2 or lower, the heights of the energy capturing components 2 are h3, h2 and h1, respectively; h3 corresponds to v1 or more, h2 corresponds to v1-v2, and h1 corresponds to v2 or less. In the actual use process, the control module directly calls a comparison table in the wind speed height mapping module, and the corresponding height is adjusted according to the measured current wind speed. It should be noted that, the wind speed v1 is higher than the wind speed of the high gear, the corresponding height h3 is lower than the wind speed v1, and when the wind speed is higher than the wind speed v1, the energy capturing component 2 with the height h3 is adopted, so that not only can the better power generation efficiency be obtained, but also the equipment is not easily damaged; the wind speed v1-v2 is the wind speed of the middle gear, the corresponding height h2 is the middle gear height, and when the wind speed v1-v2 is the wind speed, the energy capturing component 2 with the height h2 is adopted, so that not only can the better power generation efficiency be obtained, but also the equipment is not easily damaged; the wind speed below the wind speed v2 is the wind speed of a low gear, the corresponding height h1 is the height of a high gear, and when the wind speed is below the wind speed v2, the energy capturing component 2 with the height h1 can obtain better power generation efficiency and is not easy to damage equipment. It should be noted that this comparison is only an example, and in a more refined manner, the wind speed and the altitude can be divided into more levels, and the wind speed range of each level corresponds to the altitude of one level; when different wind speeds are met, different heights of the energy capturing component 2 can be adjusted, so that the safety of parts is ensured, and meanwhile, the power generation efficiency is maximized. As shown in fig. 18, the establishment of the map of the fine molecular gear is described in detail in embodiment 2, and will not be described here.
