Abstract
Description
Technical Field
[0001] This invention relates to the field of aquaculture cage installation, and more specifically, to a structure for adding aquaculture cages to offshore wind power jackets. Background Technology
[0002] In response to the needs of my country's comprehensive development of offshore wind power, a large number of offshore wind power jackets have been built. At present, the functions of offshore wind power jackets are still too limited.
[0003] Currently, aquaculture mainly involves the artificial breeding of different fish species in nearshore areas. However, some specific fish species can only be cultured in deep sea areas. In such cases, a large amount of equipment is required to meet the necessary conditions for aquaculture. Therefore, a new type of aquaculture cage structure and its integration with existing equipment can effectively simplify the workload required for platform construction.
[0004] Therefore, it is necessary to propose a structure for adding aquaculture cages to offshore wind power jackets to solve the above problems. Summary of the Invention
[0005] To overcome at least one of the defects (deficiencies) of the prior art, the present invention provides a structure for adding aquaculture cages to offshore wind power jackets.
[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a structure for adding aquaculture cages to offshore wind power jackets, comprising a cage body and steel ropes connected to the offshore wind power jacket;
[0007] The offshore wind turbine jacket structure located at sea level is equipped with lifting rings, and the top of the cage body is fixed to the lifting rings by a ratchet fastener;
[0008] The offshore wind turbine ductwork located below sea level is wrapped with perforated binding straps. The bottom of the net cage body is secured to the perforations of the binding straps via ratchet fasteners. Lifting rings are provided on the offshore wind turbine ductwork located above sea level. Since this location is above sea level, the lifting rings can be installed by welding, which facilitates the fixation of the ratchet fasteners. However, below sea level, welding is difficult and challenging, so binding straps are used for fixation, which facilitates installation and disassembly and also makes reasonable use of marine resources for fish farming.
[0009] Furthermore, the ratchet fastener includes a ratchet fastening band, a shackle, and a clamping block;
[0010] The end of the steel rope is provided with a heart-shaped loop, and the inner side of the heart-shaped loop is provided with a metal protective sleeve;
[0011] One end of the shackle is set on the lifting ring or eyelet, and the other end is connected to the heart-shaped loop on the steel rope;
[0012] The clamping block is pressed onto the ratchet fastening belt. The length of the ratchet fastening belt can be adjusted and pressed by the clamping block. The steel rope end is provided with a heart-shaped loop, and a metal protective sleeve is provided inside the heart-shaped loop, which facilitates the connection between the steel rope and the ratchet fastening belt. In addition, the shackle is provided to facilitate the ratchet fastening belt to be better installed on the offshore wind turbine jacket.
[0013] Furthermore, the bottom of the binding strap is provided with a clamp, which allows the binding strap to be better secured.
[0014] Furthermore, the clamp includes a first arc plate, a second arc plate, a hinge, and a bolt tightener;
[0015] The connection between the first and second arc plates is made by a hinge, and the open ends of the first and second arc plates are locked and fixed to the offshore wind turbine jacket after being tightened by a bolt tightener.
[0016] Furthermore, neoprene rubber pads are provided on the inner sides of the first and second arc plates, and baffles are provided on the outer sides of the first and second arc plates. The first and second arc plates can be quickly locked by the bolt tightener. Since neoprene rubber pads are provided on the inner sides of the first and second arc plates, they can strengthen the connection with the offshore wind turbine jacket. The baffles are used to fix the binding straps.
[0017] Furthermore, the offshore wind turbine jacket is equipped with a walking platform, which allows people to walk conveniently on the offshore wind turbine jacket, facilitating fishing and fish feeding.
[0018] Furthermore, the offshore wind turbine jacket is equipped with a feeding system, which facilitates the cultivation of fish while preventing feed from scattering outside the net cages.
[0019] Furthermore, the feeding system includes a feeding chamber, a feeding pipe, and a feeding float;
[0020] The feeding pod is installed on the offshore wind turbine jacket, and the feeding float is installed on the sea surface inside the cage body. The feeding pod is connected to the feeding float via a feeding pipe. With the setup of the feeding pod, feeding pipe, and feeding float, when feeding, feed can be put into the feeding pod and fed into the feeding float through the feeding pipe. Since the feeding float floats on the water surface, it can block the floating bait on the sea surface, making it easier for the fish in the cage body to eat.
[0021] Furthermore, the cage body has a grid-like structure. In practical applications, the cage body can also be configured according to the shape of the offshore wind power jacket, all of which are within the protection scope of this invention.
[0022] Furthermore, the outer side of the cage body is provided with mesh holes, the size of which is 100*100mm. Through dynamic analysis of the structure of the cage body, taking into account the dynamic response and flow obstruction effect of the netting under wave and current loads and wind loads, and modal and transient dynamic analysis of the offshore jacket, static and dynamic analysis of the structure after the cage is installed under wave and current loads and wind loads was performed. Finally, the mesh size of 100*100mm was determined.
[0023] Compared with the prior art, the beneficial effects of the technical solution of the present invention are:
[0024] The present invention discloses an offshore wind turbine jacket structure with an aquaculture cage. By setting up lifting rings on the offshore wind turbine jacket above sea level, the lifting rings can be installed by welding, which is convenient for ratchet fasteners. However, below sea level, welding is difficult and challenging, so binding straps are used for fixing, which is convenient for installation and disassembly and can also make reasonable use of marine resources for fish farming.

Detailed Implementation
[0034] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The technical solution of this invention will be further described below with reference to the accompanying drawings and embodiments.
[0036] like Figure 1-3 As shown, an offshore wind turbine jacket structure with an aquaculture cage is provided, including a cage body 1 and a steel rope 3 connected to the offshore wind turbine jacket 2. A lifting ring 4 is provided on the offshore wind turbine jacket above sea level, and the top of the cage body is secured to the lifting ring via a ratchet fastener 5. A binding strap 7 with eyelets 6 is wound around the offshore wind turbine jacket below sea level, and the bottom of the cage body is secured to the eyelets of the binding strap via a ratchet fastener. The lifting ring on the offshore wind turbine jacket above sea level can be installed by welding, facilitating the ratchet fastener's fixation. However, below sea level, welding is difficult and challenging, so binding straps are used for fixation, facilitating installation and disassembly, and also allowing for the rational utilization of marine resources for fish farming.
[0037] like Figure 4-5As shown, the ratchet fastener includes a ratchet fastening band 8, a shackle 9, and a clamping block 10; the end of the steel rope is provided with a heart-shaped loop 11, and the inner side of the heart-shaped loop is provided with a metal protective sleeve 12; one end of the shackle is set on the lifting ring or eyelet, and the other end is connected to the heart-shaped loop on the steel rope; the clamping block is pressed onto the ratchet fastening band. Due to the setting of the clamping block, the length of the ratchet fastening band can be adjusted and pressed. Since the end of the steel rope is provided with a heart-shaped loop, and the inner side of the heart-shaped loop is provided with a metal protective sleeve, it is easy for the steel rope to be connected to the ratchet fastening band. In addition, the setting of the shackle makes it easier for the ratchet fastening band to be better installed on the offshore wind turbine jacket.
[0038] like Figure 6 As shown, a clamp is provided at the bottom of the binding strap. The clamp provides better fixation for the binding strap. The clamp includes a first arc plate 13, a second arc plate 14, a hinge 15, and a bolt tightener 16. The connection between the first and second arc plates is made by the hinge. The open ends of the first and second arc plates are locked to the offshore wind turbine jacket structure by the bolt tightener. A neoprene rubber pad 17 is provided on the inner side of the first and second arc plates, and a baffle 18 is provided on the outer side of the first and second arc plates. The bolt tightener allows for quick locking of the first and second arc plates. The neoprene rubber pad on the inner side of the first and second arc plates strengthens the connection with the offshore wind turbine jacket structure, while the baffle is used to fix the binding strap.
[0039] like Figure 7-8As shown, a walking platform 19 is provided on the offshore wind turbine jacket, allowing people to walk conveniently on the jacket, facilitating fishing and fish feeding. A feeding system is also provided on the offshore wind turbine jacket, enabling convenient fish farming while preventing feed from scattering outside the cages. The feeding system includes a feeding hopper 20, a feeding pipe 21, and a feeding float 22. The feeding hopper is located on the offshore wind turbine jacket, and the feeding float is located on the sea surface inside the cage. The feeding hopper is connected to the feeding float via the feeding pipe. Through the feeding hopper, feeding pipe, and feeding float, feed can be placed from the feeding hopper and fed into the feeding float via the feeding pipe. The floating platform is designed to block floating bait on the water surface, making it easier for fish in the net cage to consume it. In this invention, the net cage has a grid-like structure. In practical applications, the net cage can also be customized according to the shape of the offshore wind turbine jacket, all of which are within the scope of this invention. The net cage has mesh openings 23 on its outer side, with a mesh size of 100*100mm. Through dynamic analysis of the net cage structure, considering the dynamic response and flow obstruction effect of the net under wave and current loads and wind loads, and modal and transient dynamic analyses of the offshore jacket, static and dynamic analyses were performed on the structure after the net cage was installed under wave and current loads and wind loads. Finally, the mesh size of 100*100mm was determined.
[0040] Example
[0041] In this embodiment, lifting rings are provided on the offshore wind turbine ductwork above sea level. Since this location is on the sea surface, the lifting rings can be installed by welding, which facilitates the fixing of the ratchet fastener. However, below sea level, welding is difficult and challenging, so binding straps are used for fixing, which facilitates installation and disassembly and also makes reasonable use of marine resources for fish farming.
[0042] During installation, neoprene rubber pads can be provided on the inner sides of the first and second arc plates, and baffles can be provided on the outer sides of the first and second arc plates. The first and second arc plates can be quickly locked by the bolt tightener. Since neoprene rubber pads are provided on the inner sides of the first and second arc plates, they can strengthen the connection with the offshore wind turbine jacket. The baffles can be used to fix the binding straps.
