Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of wind power generation, and in particular to an aquatic organism breeding auxiliary device and a wind power generator set. Background Art
[0002] Offshore wind farms are located far from land, and scouring of offshore wind turbine foundations is a slow process that cannot be detected in a timely manner through regular inspections. As water scours the surrounding soil, the bearing capacity of the offshore wind turbine foundation changes. Simultaneously, the horizontal bearing capacity of the foundation decreases as the scouring pit expands. Once the foundation's bearing capacity becomes insufficient to support the normal operation of the offshore wind turbine due to the continuous expansion of the scouring pit, the entire offshore wind turbine will become unstable and suffer accidents, resulting in huge economic losses.
[0003] In related technologies, aquaculture areas are typically set up around wind turbines, or aquaculture equipment is installed on wind turbines to reduce the flow velocity of fluid around the wind turbines to reduce scouring. However, existing aquaculture equipment often focuses on reducing scouring of wind turbine pile foundations, without considering aquaculture economics, aquaculture survival rates, and growth status, and thus cannot effectively realize the economic benefits of this aquaculture model.

[0026] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.
[0027] In this disclosure, unless otherwise indicated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the aquatic organism farming auxiliary device in normal use, and "inner" and "outer" refer to the inner and outer positions relative to the contours of the corresponding component. Furthermore, in the following description referring to the accompanying drawings, unless otherwise indicated, identical numerals in different drawings represent identical or similar elements.
[0028] According to the specific embodiment of the present disclosure, an aquatic organism breeding auxiliary device is provided, referring to Figures 1 to 4 As shown, the aquatic organism breeding auxiliary device may include a mounting structure 1 and a breeding cage 2 .
[0029] Among them, reference Figure 1 As shown, the mounting structure 1 is used to be fixedly connected to the pile foundation 200 of the wind turbine generator set 100 .
[0030] refer to Figure 1 and Figure 2 As shown, the aquaculture cage 2 can be fixedly connected to the mounting structure 1 to achieve a fixed connection with the pile foundation 200 through the mounting structure 1. The aquaculture cage 2 can be placed on the seabed, and the top of the aquaculture cage 2 can extend out of the water to prevent aquatic organisms from escaping from the aquaculture cage 2. The bottom of the aquaculture cage 2 can be constructed as an upwardly protruding conical mesh structure to form a conical space between the bottom of the aquaculture cage 2 and the seabed.
[0031] Through the above technical solution, the aquatic organism breeding auxiliary device provided by the present disclosure includes a mounting structure 1 and a breeding cage 2. The breeding cage 2 can be connected to the pile foundation 200 of the wind turbine 100 through the mounting structure 1, so as to slow down the scouring of water around the pile foundation 200. The bottom of the breeding cage 2 is constructed as an upwardly protruding conical mesh structure, so that the bottom of the breeding cage 2 is not in close contact with the seabed, but forms a conical space between the bottom and the seabed, which facilitates the discharge of metabolic waste such as feces of aquatic organisms into the conical space through the bottom of the breeding cage 2, thereby preventing these metabolic wastes from accumulating in the breeding cage 2 for a long time and affecting the breeding environment of aquatic organisms, thereby increasing the breeding efficiency of aquatic organisms. In addition, the aquatic organisms and their metabolic waste can also collect mud and sand around the pile foundation 200, thereby reinforcing the pile foundation 200.
[0032] refer to Figure 2 and Figure 3 As shown, the aquaculture cage 2 may include a cylindrical frame 20 and a net 21, wherein the cylindrical frame 20 may be fixedly connected to the mounting structure 1, and the top and bottom ends of the cylindrical frame 20 may be open. The net 21 may be arranged inside the cylindrical frame 20, and the net 21 may include side walls 211 and a bottom wall 212. The side walls 211 may be stretched between the top and bottom ends of the cylindrical frame 20 to prevent folding underwater. The bottom wall 212 may be a conical structure, and a buoyancy member 213 may be fixedly connected to the top end of the conical structure. The buoyancy member 213 may be a buoyant structure such as a floating plate or a floating ball.
[0033] Separating the net 21 from the cylindrical frame 20 facilitates regular replacement and cleaning of the net 21, thereby maintaining the cleanliness of the aquaculture cage 2. By configuring the bottom wall 212 of the net 21 as a conical structure and attaching a buoyancy member 213 to the top of the conical structure, the bottom wall 212 forms the aforementioned conical mesh structure. The buoyancy member 213, as it floats up and down in the water, drives the bottom wall 212 upward and downward, accelerating the removal of metabolic waste deposited on the bottom wall 212. Furthermore, it promotes the movement of aquatic organisms at the bottom of the aquaculture cage 2. This increased movement of the aquatic organisms contributes to improved taste and quality.
[0034] In addition, in order to slow down the impact of water flow and foreign matter on the aquaculture cage 2, refer to Figure 1 and Figure 4 As shown, the aquaculture cage 2 may further include a guard plate 22 extending horizontally outward in the radial direction of the aquaculture cage 2. The guard plate 22 may include an annular outer frame 220 and a buffer plate 221. The buffer plate 221 may be disposed in the annular outer frame 220. Specifically, the annular outer frame 220 may be fixedly connected to the cylindrical frame 20 described above, and the buffer plate 221 is connected to the annular outer frame 220. When foreign matter or water flow impacts the aquaculture cage 2, the annular outer frame 220 and the buffer plate 221 can absorb a portion of the kinetic energy to mitigate the impact on the aquaculture cage 2, thereby preventing the aquaculture cage 2 and the pile foundation 200 from deforming.
[0035] In order to further increase the energy absorption effect of the guard plate 22, refer to Figure 4 As shown, the buffer plate 221 and the annular outer frame 220 can be connected by a flexible connecting rod 222. When the buffer plate 221 moves relative to the annular outer frame 220 under the action of the water flow, the flexible connecting rod 222 can produce flexible deformation, which can further absorb kinetic energy. In addition, the swing of the buffer plate 221 with the water flow can not only consume water energy, reduce the flow rate of water entering the aquaculture cage 2, thereby further reducing the erosion of the aquaculture cage 2 and the pile foundation 200 by the water flow, but also drive away foreign organisms approaching the aquaculture cage 2.
[0036] In order to further increase the protective effect of the guard plate 22, refer to Figure 3 As shown, a plurality of guard plates 22 may be arranged at intervals around the circumference of the aquaculture cage 2 , and / or a plurality of guard plates 22 may be arranged at intervals along the central axis of the aquaculture cage, so that the outer periphery of the aquaculture cage 2 can be protected by the guard plates 22 .
[0037] refer to Figure 1 and Figure 2 As shown, the aquatic life breeding auxiliary device may include a plurality of breeding cages 2, and the plurality of breeding cages 2 may be arranged in an array around the central axis of the pile foundation 200 to protect the pile foundation 200 from scouring along its circumference.
[0038] refer to Figure 1 and Figure 2As shown, the mounting structure 1 may include a mounting hoop 10 and a connecting plate 11. The mounting hoop 10 may be sleeved and tightened onto the pile foundation 200. The connecting plate 11 may be fixedly connected to the mounting hoop 10 and extend radially outward from the mounting hoop 10. The aquaculture cages 2 may be fixedly connected to the connecting plate 11. When the aquatic organism aquaculture auxiliary device includes multiple aquaculture cages 2, the mounting hoop 10 may be provided with multiple connecting plates 11. The multiple connecting plates 11 may be arranged in an array around the central axis of the mounting hoop 10 (i.e., the central axis of the pile foundation 200), with each connecting plate 11 fixedly connected to a single aquaculture cage 2.
[0039] In order to facilitate the installation of the aquaculture cage 2 and the connecting plate 11 , the connecting plate 11 and the cylindrical frame 20 of the aquaculture cage 2 may be fastened together by fasteners (not shown).
[0040] In order to ensure the connection reliability between the mounting hoop 10 and the pile foundation 200, refer to Figure 1 and Figure 2 As shown, the mounting hoop 10 may include two mounting rings 101, which may be spaced apart along the central axis of the mounting hoop 10 (i.e., the central axis of the pile foundation 200). The two mounting rings 101 may be connected via a plurality of connecting columns 102, and the connecting plate 11 may be fixedly connected to one of the two mounting rings 101. The two mounting rings 101 provide sufficient contact area between the mounting hoop 10 and the pile foundation 200, thereby increasing the reliability of the connection between the mounting hoop 10 and the pile foundation 200.
[0041] As another embodiment not shown, the mounting hoop 10 may be constructed as a mounting sleeve. The mounting sleeve has a certain length along the central axis of the pile foundation 200 to ensure a sufficient contact area with the pile foundation 200 .
[0042] To facilitate assembly of the mounting ring 101 and the pile foundation 200 , the mounting ring 101 may be formed by splicing two semicircular ring structures (not shown), the ends of which may be connected by fasteners (not shown) to be clamped to the pile foundation 200 .
[0043] On the basis of the above technical solution, the present disclosure further provides a wind turbine generator set, comprising: a pile foundation 200, the bottom end of the pile foundation 200 is inserted into the seabed, and an aquatic organism breeding auxiliary device of the above technical solution.
[0044] Through the above technical solution, the wind turbine generator set provided by the present disclosure has the same technical effect as the aquatic organism breeding auxiliary device in the above technical solution. In order to avoid unnecessary repetition, it will not be described here.
[0045] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
