Description

Technical Field

[0001] The present application relates to the field of wind power tower equipment, and in particular to a spoiler strip for effectively preventing vortices. Background Art

[0002] Against the backdrop of the depletion of global fossil energy and severe climate change, wind energy has become increasingly strategically valuable as a renewable, clean energy with little environmental impact. All countries attach great importance to wind energy, and large-scale offshore power generation is a new market industry, so experience in similar engineering construction is very scarce.

[0003] As offshore wind power projects get farther from shore, the sea conditions become more severe. In order to prevent vortex vibration from occurring in the top section of the tower, spoiler strips are usually installed on the wind power tower. Existing spoiler strips usually have a fixed structure and cannot effectively disrupt the regular discharge of the vortex in the wake field of the wind power tower. Utility Model Content

[0004] In order to improve the problem of fixing the existing spoiler strip structure, the present application provides a spoiler strip that effectively prevents vortices.

[0005] The present application provides an effective anti-vortex spoiler strip adopting the following technical solution:

[0006] A spoiler strip for effectively preventing vortex, comprising

[0007] A spoiler assembly, comprising a bag and a filler, wherein the bag is used to destroy the vortex in the wake field of the wind power tower, and the filler is arranged in the bag;

[0008] The limiting assembly comprises a shell and an end plate, wherein the shell is connected to the bladder bag, and the end plate is connected to the shell to limit the position of the bladder bag.

[0009] By adopting the above technical solution, the shell supports the bag and limits the position of the bag through the end plate, and the filler in the bag makes the bag bulge; when the airflow passes through, the bag swings with the wind and dynamically responds to the changes in the airflow, generating irregular airflow disturbances and directly acting on the wake field of the power tower, improving the problem of fixing the existing spoiler strip structure, and effectively destroying the regular discharge of the vortex in the wake field of the wind power tower.

[0010] Preferably, the spoiler assembly further comprises a cylinder, an outer wall of the cylinder is connected to the bladder, and an inner wall of the cylinder is used to be connected to an outer wall of the shell.

[0011] By adopting the above technical solution, the cylinder can expand the bag and limit the position of the bag by connecting with the shell, so as to prevent the bag from being deformed by the airflow and sliding along the length direction of the shell. While maintaining the shape and position of the spoiler strip, the spoiler strip can interfere with the vortex in the wake field, further improving the problem of fixing the existing spoiler strip structure, and effectively disrupting the regular discharge of the vortex in the wake field of the wind turbine tower.

[0012] Preferably, the shell includes a main body and a support rod, the outer wall of the main body is connected to the inner wall of the cylinder, the support rod is inserted into the main body along the length direction of the main body, both ends of the support rod protrude from the main body, and the support rod is used to connect to the end plate.

[0013] By adopting the above technical solution, the connection between the main body and the cylinder can provide an installation environment for the spoiler assembly, and the connection between the support rod, the main body and the end plate can form a rigidly connected whole, avoiding separation of the main body and the end plate when the airflow is large, thereby ensuring the structural stability of the shell.

[0014] Preferably, one side of the end plate is connected to the support rod, and one side of the end plate close to the support rod is in contact with the bladder bag to limit the position of the bladder bag.

[0015] By adopting the above technical solution, when the bladder is blown by the airflow, the end plate can contact the bladder, thereby limiting the movement range of the bladder and avoiding safety risks caused by excessive swinging of the bladder, such as collision and falling off, thereby ensuring that the spoiler effect of the spoiler strip is stable and effective.

[0016] Preferably, a rope clamp is provided on a side of the end plate away from the support rod.

[0017] By adopting the above technical solution, the rope clamp can allow several spoiler strips to be connected into a whole, so that the several spoiler strips form a synergistic spoiler system, which increases the versatility of the spoiler strip; at the same time, the rope clamp provides a simple and easy-to-understand installation method for the spoiler strip, reduces the installation time of the spoiler strip, and improves the installation efficiency of the spoiler strip.

[0018] Preferably, the spoiler assembly further comprises a packaging bag, and the packaging bag is used to contain the filler.

[0019] By adopting the above technical solution, the packaging bag contains the filler and is placed in the pouch, which can alleviate the irregular movement of the filler when the pouch is blown by the airflow and reduce the excessive deformation of the pouch, thereby avoiding the pouch from rupturing and extending the service life of the pouch; at the same time, if the pouch ruptures, the packaging bag can prevent the filler from scattering everywhere, which is convenient for the subsequent recovery of the filler.

[0020] Preferably, a plurality of the packaging bags are provided, and the plurality of packaging bags are arranged in the pouch.

[0021] By adopting the above technical solution, several packaging bags can provide structural stability for the bags while ensuring the deformation of the bags, thereby ensuring that the bags will not be excessively deformed, and further improving the problem of fixing the existing spoiler strip structure, effectively destroying the regular discharge of the vortex in the wake field of the wind turbine tower.

[0022] Preferably, the packaging bag is a degradable bag, and the filler is a plurality of degradable spheres.

[0023] By adopting the above technical solution, when the tower is in an environment where it is difficult to recycle the filler, such as in the ocean or on a mountain top, the bag ruptures, causing the packaging bag and the filler to separate from the bag. The degradable packaging bag and degradable filler can reduce the pollution to the environment when the filler cannot be recovered, which meets the current requirements of sustainable development and environmental protection.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The shell supports the bag and limits the position of the bag through the end plate. The filler in the bag makes the bag bulge. When the airflow passes through, the bag swings with the wind and dynamically responds to the change of the airflow, generating irregular airflow disturbances and directly acting on the tail flow field of the power generation tower, improving the problem of the existing spoiler strip structure fixation, and effectively destroying the regular discharge of the vortex in the tail flow field of the wind power generation tower;

[0026] 2. The cylinder can open the bag and limit the position of the bag by connecting with the shell, so as to prevent the bag from being deformed and sliding along the length direction of the shell due to the blowing of the airflow. Under the condition of maintaining the shape and position of the spoiler strip, the spoiler strip can interfere with the vortex in the wake field, further improving the problem of fixing the existing spoiler strip structure, and effectively destroying the regular discharge of the vortex in the wake field of the wind power tower;

[0027] 3. The connection between the main body and the cylinder can provide an installation environment for the spoiler assembly, and the connection between the support rod, the main body and the end plate can form a rigidly connected whole, avoiding the separation of the main body and the end plate when the airflow is large, thereby ensuring the structural stability of the shell.

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The present application embodiment discloses an effective vortex-preventing spoiler strip (hereinafter referred to as spoiler strip). Figure 1 The spoiler strip includes a limiting component 1 and a spoiler component 2.

[0037] like Figure 2 and Figure 3 As shown, the limiting assembly 1 includes a shell 11 and an end plate 12 .

[0038] refer to Figure 3 The shell 11 includes a main body 111 and a support rod 112. The outer surface of the main body 111 is used to connect with the spoiler assembly 2 and provide an installation environment for the spoiler assembly 2. The support rod 112 is inserted into the main body 111 along the length direction of the main body 111, and both ends of the support rod 112 protrude from the main body 111.

[0039] Two end plates 12 are provided, and the two ends of the support rod 112 are respectively connected to one side of the two end plates 12, so that the support rod 112, the main body 111 and the two end plates 12 form a rigidly connected whole, avoiding the main body 111 and the two end plates 12 from being separated due to the movement of the spoiler assembly 2 when the airflow is too large, ensuring the stability of the structure of the shell 11 and improving the working stability of the spoiler.

[0040] like Figure 1As shown, a rope clamp 13 is provided on one side of the two end plates 12 away from the support rod 112, and a plurality of spoiler strips can be connected into a whole through the rope clamp 13, so that the plurality of spoiler strips form a synergistic spoiler system, thereby increasing the versatility of the spoiler strips. It should be noted that the number of spoiler strips needs to be set according to actual conditions, and the embodiments of the present application do not impose specific restrictions.

[0041] At the same time, the rope clamp 13 provides a simple and easy-to-understand connection method for several spoiler strips. By connecting or separating two rope clamps 13 of two spoiler strips, two spoiler strips can be connected or separated, reducing the connection time of connecting several spoiler strips and improving the installation efficiency of the spoiler strips.

[0042] like Figure 4 and Figure 5 As shown, the spoiler assembly 2 includes a bag 21, a cylinder 22, a packaging bag 23 and a filler 24. The bag 21 is connected to the shell 11 through the cylinder 22 to limit the position of the bag 21. The filler 24 is arranged in the bag 21 to make the bag 21 bulge. When the airflow passes through, the bag 21 swings with the wind and dynamically responds to the change of the airflow, generating irregular airflow disturbances and directly acting on the wake field of the power generation tower, thereby improving the problem of fixing the existing spoiler strip structure and effectively destroying the regular discharge of the vortex in the wake field of the wind power generation tower.

[0043] Specifically, refer to Figure 5 The bag 21 is connected to the outer wall of the cylinder 22, so that the bag 21 can be fully unfolded to avoid partial collapse of the bag 21; the length of the cylinder 22 is the same as the length of the shell, and the inner wall of the cylinder 22 is connected to the outer surface of the main body 111 to limit the position of the bag 21, avoiding the bag 21 from being deformed by the airflow and sliding along the length direction of the shell. While maintaining the shape and position of the spoiler strip, the spoiler strip is ensured to interfere with the vortex in the wake field, further improving the problem of fixing the existing spoiler strip structure, and effectively destroying the regular discharge of the vortex in the wake field of the wind power tower.

[0044] When the bag 21 is blown by the airflow, the bag 21 can contact the side of the end plate 12 close to the support rod 112, thereby limiting the movement range of the bag 21 and avoiding safety risks caused by excessive swinging of the bag 21, such as collision and falling off, thereby ensuring that the spoiler effect of the spoiler strip is stable and effective.

[0045] like Figure 5As shown, a plurality of packaging bags 23 are provided, each of which is provided with a filler 24. The plurality of packaging bags 23 are arranged in the pouch 21. The packaging bags 23 contain the filler 24 and are placed in the pouch 21. This can alleviate the irregular movement of the filler 24 when the pouch 21 is blown by the airflow, reduce the excessive deformation that may occur to the pouch 21, thereby avoiding the rupture of the pouch 21 and extending the service life of the pouch 21. At the same time, the plurality of packaging bags 23 can provide structural stability for the pouch 21 while ensuring the deformation of the pouch 21, thereby ensuring that the pouch 21 will not be excessively deformed.

[0046] When the bag 21 ruptures due to excessive airflow, the packaging bag 23 can prevent the filler 24 from scattering, thereby facilitating the subsequent recovery of the filler 24. It should be noted that, considering that the tower may be located in an environment where it is difficult to recover the filler 24, such as a marine environment or other extreme environment, the packaging bag 23 and the filler 24 are both made of degradable materials, including but not limited to polylactic acid and all-starch plastics. When the bag 21 ruptures and the packaging bag 23 and the filler 24 are separated from the bag 21, the degradable packaging bag 23 and the degradable filler 24 can reduce the pollution to the environment when the filler 24 cannot be recovered, which meets the current requirements of sustainable development and environmental protection.

[0047] like Figure 6 As shown, when the airflow blows the bag 21, the bag 21 will undergo irregular deformation and swing. At this time, the spoiler strip generates complex airflow disturbances through the irregular deformation and swinging of the bag 21, disrupting the stable structure of the airflow, thereby destroying the vortex morphology in the wake field and reducing vortex-induced vibration, improving the problem of fixing the existing spoiler strip structure, and effectively destroying the regular discharge of the vortex in the wake field of the wind turbine tower.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
