Description

Technical Field

[0001] The invention relates to the technical field of offshore platforms, and specifically proposes an offshore combined platform. Background Art

[0002] An offshore platform generally refers to a fixed or floating platform structure established in the ocean. Depending on the function of the platform, it includes but is not limited to an oil and gas extraction platform, a wind farm platform, an aquaculture platform, and a scientific research observation platform, among which an aquaculture platform mainly refers to a cage culture platform, which is mainly used for the cultivation of fish and other aquatic organisms. The offshore combined platform described in the present invention specifically refers to an offshore culture platform, which can get rid of the problems of limited space in the near-coastal area and the susceptibility of seawater to pollution, and improve the efficiency and output of aquaculture.

[0003] Existing offshore aquaculture platforms use cage aquaculture, which are basically square cages or round cages. Regardless of whether they are floating, semi-submersible or fully submersible cages, their aquaculture areas are all located in the seawater. Existing aquaculture cages will more or less have the following problems in the actual aquaculture process, which affects the aquaculture efficiency and aquaculture output.

[0004] 1) The inner net of the existing aquaculture cage is generally fixed on the fishing net support frame, and is further fixed by sinking stones or anchor hooks to ensure the stability of the aquaculture cage in the seawater layer. However, aquaculture cages are generally located in sea areas tens of meters deep. The ocean is windy and rough, and there are generally undercurrents in the seawater layer. The cages will be repeatedly impacted by wind and waves and undercurrents. The existing methods basically rely on gravity and seabed anchoring. The aquaculture cages lack their own stable structure, so there are limitations. When the wind and waves are fierce, it is impossible to guarantee a relatively stable aquaculture state.

[0005] 2) Aquaculture cages provide a relatively isolated aquaculture environment. In order to improve the health and growth efficiency of aquaculture organisms, it is necessary to ensure the fluidity of seawater in the aquaculture cages, thereby increasing the oxygen content in seawater, improving water quality, promoting the discharge of waste, and creating living conditions that are closer to the surrounding sea environment. Under existing technologies, oxygen pumps are often used to improve the fluidity of seawater, but the area of ​​aquaculture cages is generally large, and oxygen pumps act on local waters, with limited actual effects, and it is difficult to ensure the uniformity of water quality in various areas of the aquaculture cages.

[0006] 3) As time goes by, the nets on the cages will gradually accumulate various biological attachments, such as shellfish, algae and other microorganisms, and the feed will also accumulate in the aquaculture cages. These attachments will not only clog the mesh and reduce water exchange, but may also affect the oxygen supply and the circulation of nutrients inside and outside the cages, thereby adversely affecting the growth of farmed fish. In addition, too much sediment attachment will increase the weight of the cages, which may cause the nets to break or the structure to deform. Therefore, it is inevitable to clean the aquaculture cages regularly. Under the existing technology, the aquaculture cages are mostly cleaned by water gun flushing or manual brushing, which is difficult to clean. Therefore, how to slow down the deposition and attachment speed of the sediment attachments in the aquaculture cages is a feasible way to reduce the cleaning frequency of the aquaculture cages and maintain the aquaculture environment of the aquaculture cages.

[0007] The invention patent with application number 2014108481118.8 discloses a wave-proof offshore mobile platform, which has the function of effectively resisting offshore wind and waves and achieving self-balancing.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1

[0036] like Figure 1As shown, an offshore combined platform includes a floating platform 1 with its own navigation power assembly and anchored by a ship anchor; the invention patent with application number 2014108481118.8 discloses a wave-proof offshore mobile platform, which has the function of effectively resisting wind and waves at sea and realizing self-balancing. The floating platform 1 is based on the mobile platform proposed in the above invention, has a corresponding navigation power assembly for sailing on the sea surface, and can be anchored and fixed on the sea surface by an anchor. In addition, the floating platform 1 also has the function of resisting wind and waves and realizing self-balancing to ensure the stability of the platform on the sea surface after anchoring. As an existing public technology, the navigation power assembly and anchor and other components and assembly methods in the floating platform 1 are not specifically shown in the attached drawings. It should be added that in order to increase the buoyancy, fixed buoys can be evenly distributed at the bottom of the floating platform 1. In the present invention, the floating platform 1 is a square platform, and a house 12 for fishermen to live in is fixed on the floating platform 1. The house 12 is equipped with equipment required for fishery production and daily living equipment, which can meet the daily fishery production and daily living needs of fishermen, so that fishermen can carry out fishery production in ocean areas far away from the coast. In order to meet the electricity demand, the floating platform 1 adopts photovoltaic power generation to supply daily electricity. The photovoltaic panel 13 can be installed on the roof of the house 12, or in other open areas on the floating platform 1. In addition, a small wind turbine can also be installed to generate wind power to make full use of sea breeze resources and make up for the deficiency of photovoltaic power generation in rainy weather.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a circular hole-shaped cage window 11 is opened at the center of the floating platform 1, and a plurality of houses 12 are basically evenly distributed around the cage window 11 to ensure the overall balance of the floating platform 1; a breeding cage 2 for fishery farming is installed on the floating platform 1; in the present invention, the breeding cage 2 is an existing circular floating cage; different from the traditional circular floating cage for farming alone that floats directly on the sea surface, in the present invention, the breeding cage 2 is embedded in the cage window 11 and is directly fixed on the floating platform 1; specifically, the breeding cage 2 includes a circular frame 21 and a net support frame 22 fixed at the bottom end of the circular frame 21; the circular frame 21 is embedded in the cage window 11 and overlapped on the table top of the floating platform 1, and can be locked by bolts, and the circular frame 21 is provided with an annular enclosure for safety protection. Fence 211; the net-supporting frame 22 is used to open and fix the fishing net. The net-supporting frame 22 includes a sinking ring 222 located below the circular frame 21. The sinking ring 222 can be a circular ring with an iron ring as an internal skeleton and a rubber layer wrapped on the outside; a plurality of side-tensioning cables 221 for jointly fixing the fishing net are connected between the sinking ring 222 and the circular frame 21. The side-tensioning cables 221 are evenly distributed in the circumference of the sinking ring 222. In addition, there is also a lower support net structure composed of woven cables in the circular ring of the sinking ring 222, and the lower support net is opened and fastened to the sinking ring 222; the net-supporting frame 22 constitutes a fixed frame for the aquaculture fishing net. The fishing net can be tied to the side-tensioning cables 221 and the cables of the lower support net by ropes. When the entire aquaculture net box 2 is lifted, the sinking ring 222 keeps the side-tensioning cables 221 drooping, and the fishing net is in a basically open state. It should be noted that the lower support net and the aquaculture fishing net are not shown in the drawings. In order to ensure the service life of the aquaculture cage 2, the cables and the fishing nets are made of elastic, tough and corrosion-resistant materials by default, such as nylon or other materials.

[0038] like Figure 1 and Figure 2 As shown, since the aquaculture cage 2 is fixed on the floating platform 1, when the floating platform 1 is anchored and fixed, it is equivalent to primary fixation of the aquaculture cage 2, but the structural part of the aquaculture cage 2 extending into the sea water still needs to be fixed. Different from the existing fixing method described in the background technology, in the present invention, a plurality of inclined-stayed mechanisms 3 are installed on the aquaculture cage 2, and the plurality of inclined-stayed mechanisms 3 are distributed on the periphery of the aquaculture cage 2 and are evenly distributed around the aquaculture cage 2. The number of inclined-stayed mechanisms 3 to be installed depends on the specific diameter size of the aquaculture cage 2. When the size of the aquaculture cage 2 is large, the number of inclined-stayed mechanisms 3 can be reasonably increased to ensure the actual inclined-stayed fixing effect.

[0039] like Figure 3 , Figure 5 and Figure 6As shown, the inclined-stayed mechanism 3 includes a connecting frame 31. In order to disperse the pulling points and enhance the pulling effect, the connecting frame 31 includes a plurality of connecting blocks 311 evenly distributed and fixed on the sinking ring 222. The connecting block 311 is an arc-shaped sleeve. The connecting block 311 can be a half-split structure. When the two halves of the connecting block 311 are relatively assembled and clamped on the sinking ring 222, they can be locked by bolts. It should be noted that the specific installation structure features of the connecting block 311 are not shown in the figure. A series plate 312 is fixed between the connecting blocks 311 by screws; a retractable and elastic telescopic cylinder 32 is hinged on the connecting frame 31, and the retractable and elastic telescopic cylinder 32 includes a cylinder sleeve 321 hinged on the series plate 312 and a telescopic rod 322 slidably installed in the cylinder sleeve 321, and a tension spring 323 is arranged in the cylinder sleeve 321, and the two ends of the tension spring 323 are respectively fixed to the inner wall of the cylinder sleeve 321 and the end of the telescopic rod 322 by screws; a pull rope 33 is fixed to the outer shaft end of the telescopic rod 322.

[0040] like Figure 3 , Figure 5 and Figure 6 As shown, a rope guide 34 for guiding the pull rope 33 is fixed on the circular frame 21; the rope guide 34 includes a guide tube 342 extending vertically into the seawater, roller frames 343 are symmetrically fixed at both ends of the guide tube 342, and guide rollers 344 are installed horizontally on the two roller frames 343. The roller frame 343 at the upper end is fixed with a fixing frame 341 by screws, and the fixing frame 341 is fixed on the circular frame 21 by bolts. The pull rope 33 passes through the guide tube 342 and bypasses the two guide rollers 344. A winch motor that can provide a large torque can be installed on the circular frame 21 to perform the retractable operation of the pull rope 33. The retractable operation of the pull rope 33 by the winch motor is a prior art, and the winch motor and its supporting structure are not shown in the attached drawings. The pull rope 33 can be pulled along a specified path by the rope guide 34. Under the guidance of the rope guide 34, the pull rope 33 is in a tilted downward inclined state for the elastic telescopic cylinder 32.

[0041] When the aquaculture net cage 2 is assembled, the inclined-stayed mechanism 3 can be assembled on the aquaculture net cage 2, and then it can be hoisted and assembled on the floating platform 1 by a large crane, and the aquaculture net cage 2 can be further fixed by the synchronous cooperation of multiple inclined-stayed mechanisms 3. Specifically, the pull rope 33 is reeled in by the winch motor, and the pull rope 33 pulls the telescopic rod 322 to slide outward, so that the tension spring 323 is gradually lengthened, and the tension spring 323 further pulls the connecting frame 31 through the sleeve 321, and then the connecting frame 31 pulls the sinking ring 222 downward, so that under the tensioning cooperation of multiple inclined-stayed mechanisms 3, the net-supporting frame 22 and the fishing net are in a taut state, and indirectly maintain a relative locking state between the winch motor and the circular ring frame 21. In addition, the tension of the fishing net can be adjusted by retracting and releasing the control pull rope 33. Compared with the existing fixing method, it can better maintain the overall stability of the aquaculture net cage 2, which is convenient for fishery.

[0042] In addition, if Figure 3 , Figure 5 and Figure 6 As shown, a spoiler assembly 35 for enhancing the flow of seawater is installed between the connecting frame 31 and the elastic telescopic cylinder 32, and a swinging flapper 36 for flapping the bottom of the breeding cage 2 is installed on the spoiler assembly 35; the spoiler assembly 35 includes a spoiler 351. In order to reduce the dead weight of the spoiler 351 and reduce the pulling load of the pull rope 33, the spoiler 351 adopts a lightweight design as a whole. The spoiler 351 includes a plate frame 3511 hinged on the serial plate 312, and a spoiler mesh 3512 is fixed in the frame of the plate frame 3511. The spoiler mesh 3512 itself is permeable. When the seawater is disturbed by the spoiler mesh 3512, the seawater can also flow normally through the spoiler mesh 3512. After long-term use, the spoiler mesh 3512 will inevitably be attached with seaweed and other debris, which reduces the water permeability. However, it should be noted that in the present invention, the spoiler mesh 3512 mainly provides a disturbing effect on the seawater. The spoiler 351 is located above the elastic telescopic cylinder 32, and a connecting rod 352 is hinged between the spoiler 351 and the telescopic rod 322. The swinging clapper 36 is fixed on the spoiler 351, and the swinging clapper 36 includes two swing arms 361 fixed to both sides of the plate frame 3511 by bolts. The swing arms 361 are in a right-angle bent plate structure, and the swing arms 361 are bent sideways to extend to the bottom of the breeding net box 2. The two swing arms 361 extend to the bottom of the breeding net box 2. The parts of the two swing arms 361 are fixed with a slapping plate 362 by screws. In order to avoid the slapping plate 362 made of hard material from slapping contact with the fish at the bottom of the breeding net box 2 and causing damage, a brush body layer 3621 is fixed on the board surface of the slapping plate 362 facing the bottom of the breeding net box 2. The brush body layer 3621 is made of nylon brush hair material, and the brush body layer 3621 will directly contact the lower support net of the breeding net box 2.

[0043] It should be added that, in order to avoid seawater corrosion, the inclined-stayed mechanism 3 except the fixing frame 341 and the tension spring 323 is made of non-metallic materials mainly composed of high-strength plastic, and the bolts and screws used for fixing are also made of plastic.

[0044] Under the reciprocating pulling of the pull rope 33, the flow of seawater in the aquaculture cage 2 can be enhanced by the spoiler assembly 35, and the aquaculture cage 2 can be slapped and cleaned synchronously by the swinging clapper 36; specifically, when the pull rope 33 is driven by the winch motor to reciprocate and release, the telescopic rod 322 reciprocates accordingly, so that the oblique pulling force of the elastic telescopic cylinder 32 on the aquaculture cage 2 produces a dynamic change, and then the tension of the aquaculture cage 2 changes synchronously, which is manifested as the aquaculture cage 2 itself produces an up and down reciprocating shaking, and the sediment attachments on the aquaculture cage 2 can be cleaned to a certain extent by shaking; when the telescopic rod 322 is in a reciprocating extension and contraction state, it will drive the spoiler 351 to swing back and forth through the connecting rod 352, and the spoiler 351 will promote the reciprocating flow of water during the reciprocating swinging process, and the seawater in the aquaculture cage 2 and the surrounding external seawater will be actively exchanged and flowed through the mutual cooperation of multiple circumferentially distributed spoilers 351, and while the seawater is exchanging and flowing, the aquaculture cage 2 will be synchronously The waste in the cage 2 is discharged outward, which increases the oxygen content of the seawater in the breeding area, improves the environmental water quality, and improves the consistency of the water quality and temperature between the seawater in the breeding area and the seawater in the external area. The multiple spoilers 351 cover the circumference of the breeding cage 2 and the breeding depth, which improves the limitation of using an oxygen pump for local oxygenation and improves the actual effect of seawater flow exchange. In addition, when the spoiler 351 swings, the swinging clapper 36 swings synchronously, and the swinging clapper 36 repeatedly touches and beats the small support net through the brush body layer 3621, so as to further enhance the overall shaking effect of the breeding cage 2 and promote the rapid cleaning and separation of the attachments deposited on the lower support net. By shaking the breeding cage 2 up and down and beating the bottom, a large amount of deposition and attachment of debris on the breeding cage 2 is avoided, and the attachment and deposition speed is slowed down, so that the breeding cage 2 can maintain a better breeding state for a long time, and then the frequency of manual cleaning of the breeding cage 2 as a whole can be reduced.

[0045] It should be added that, most of the time, the inclined-stayed mechanism 3 mainly plays the role of inclined-staying and stabilizing the aquaculture cage 2. The inclined-stayed mechanism 3 can be activated and executed regularly to enhance the flow of seawater and actively clean the aquaculture cage 2.

[0046] The present invention provides an offshore combined platform, which is provided with a floating platform 1 that can be lived in and navigated, and a breeding cage 2 for fishery breeding is installed on the floating platform 1, forming a comprehensive platform for both living and fishery production. In addition, a plurality of inclined-stayed mechanisms 3 are distributed and installed on the breeding cage 2. On the basis of the preliminary stabilization of the breeding cage 2 by the floating platform 1, the breeding cage 2 can be inclined and fixed by the cooperation of the plurality of inclined-stayed mechanisms 3, and the tension of the breeding cage 2 can be reasonably adjusted according to the specific sea environment, and the breeding is enhanced by the self-stable structural design. The inclined-stayed mechanism 3 has a stabilizing effect on the cage 2; a spoiler 351 for disturbing seawater and a swinging clapper 36 for beating the bottom end of the aquaculture cage 2 are also provided in the inclined-stayed mechanism 3, so that the aquaculture cage 2 can be shaken and cleaned by reciprocating pulling and tensioning of the inclined-stayed mechanism 3, and the aquaculture cage 2 is reciprocatedly beat while disturbing the seawater to enhance the flow; the inclined-stayed mechanism 3 has multiple functions for the aquaculture cage 2, including inclined-stayed stabilization, seawater flow exchange and cleaning of deposited attachments, which greatly improves the controllability of the aquaculture cage 2, can effectively improve the aquaculture environment, and then improve the efficiency of fishery aquaculture.
