Description

Technical Field

[0001] The present disclosure relates to the technical field of seabed aquaculture, and in particular, to a construction method and aquaculture system for a seabed aquaculture system. Background Art

[0002] The key to deep-sea aquaculture lies in aquaculture equipment, namely aquaculture cages. Common aquaculture cages currently include gravity cages, truss cages, aquaculture platforms, aquaculture work boats and other types. Among them, mobile bottom-seated aquaculture cages, as an important type of cage, are often used in sea areas with a water depth of 15m~40m. Mobile bottom-seated cages have the advantages of movable position, stable bottom, and convenient net replacement. However, since the cages need to be seated on the bottom, the requirements for the seabed are also high. Generally, the seabed is required to be flat and have strong bearing capacity. Before the cages are seated on the bottom, detailed seabed topography surveys are required. If the seabed is uneven, seabed leveling operations are required. In case of weak foundations, seabed replacement and other construction are required. This brings great difficulties to the adaptability and application promotion of bottom-seated cages. In addition, when the net of the cage needs to be replaced, it is also necessary to float the cage to the sea surface for replacement, and then place the cage on the bottom. During the floating and sinking process of the cage, it is easy to deviate from the original position. Therefore, during the early stage of seabed leveling, the deviation caused by the replacement of the net is often also considered, which increases the amount of engineering work in the early stage. Summary of the invention

[0011] Optionally, the construction method comprises: A water transport pipeline is arranged in the column and is connected to the first accommodating cavity and the second accommodating cavity respectively.

DETAILED DESCRIPTION

[0025] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" are defined for the layout direction of the aquaculture system when it is actually used, and directional words such as "inner" and "outer" are defined for the outline of the corresponding components. The use of terms such as "first" and "second" is intended to distinguish different components and does not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0027] According to one embodiment of the present disclosure, Figures 1 to 6As shown, a construction method for a submarine aquaculture system is provided, comprising the following steps: first, a base 1 is constructed in the seabed 7, and a positioning member 5 is fixedly connected to the base 1; second, an aquaculture cage assembly is made, and the aquaculture cage assembly is movably placed above the base 1; then, a reel 4 is arranged above the aquaculture cage assembly; after the reel 4 is arranged, the end of the positioning member 5 away from the base 1 is passed through the aquaculture cage assembly and retractably connected to the reel 4. In this way, since the positioning member 5 is passed through the aquaculture cage assembly, the positioning member 5 can limit the aquaculture cage assembly, and the aquaculture cage assembly can move along the extension direction of the positioning member 5. Here, the aquaculture cage assembly can include a lifting assembly, and the lifting assembly can be a linear lifting mechanism, or it can be a buoy 2 described below, and the present disclosure does not limit this.

[0028] Through the above technical solution, the base 1 is set in the seabed 7 to replace the filling work of the seabed 7, which can reduce the initial operation time. Since the bottom of the aquaculture cage assembly is located on the base 1, the mud surface of the seabed 7 has no suction on the bottom of the aquaculture cage assembly, and the aquaculture cage assembly can be easily lifted, effectively improving the maintenance and harvesting efficiency. The positioning member 5 is inserted into the aquaculture cage assembly, which can not only play the role of a mooring anchor chain when the lower part of the aquaculture cage assembly floats to the sea level 8, but also eliminate the need for the setting of a mooring anchor chain. At the same time, when the aquaculture cage assembly is raised or lowered, the reel 4 can effectively ensure that the aquaculture cage assembly moves along the extension direction of the positioning member 5, thereby ensuring that the aquaculture cage assembly can still be located on the base 1 when it is re-located on the seabed 7 without shifting.

[0029] When the aquaculture cage assembly sinks, the reeling member 4 reels the positioning member 5 at the same time, so that the descending speed of the aquaculture cage assembly and the reeling member 4 is consistent, until the lower part of the aquaculture cage assembly is seated on the base 1. When the aquaculture cage assembly is seated on the base 1, the upper edge of the aquaculture cage assembly and the reeling member 4 are both above the sea level. When the aquaculture cage assembly needs to be repaired or the seafood is harvested, the aquaculture cage assembly is manipulated to float up, and the reeling member 4 releases the positioning member 5 at the same time, until the lower part of the aquaculture cage assembly is exposed to the sea level 8, so as to carry out the repair and harvesting work.

[0030] It should be noted that, here, the reeling member 4 can be a winch, the positioning member 5 can be a wire rope, the reeling member 4 can be set in one-to-one correspondence with the positioning member 5, or one reeling member 4 can correspond to multiple positioning members 5, and the present disclosure does not limit this. In the scheme where the reeling member 4 corresponds to the positioning member 5 one-to-one, multiple positioning members 5 can be arranged at intervals, and the corresponding connected reeling members 4 are also arranged at intervals to enhance the anchoring ability of the positioning member 5 to prevent the possibility of displacement during the rise and fall of the aquaculture net cage assembly when the sea waves are too large. Take the structure of the aquaculture net cage assembly including the buoy 2 and the aquaculture net cage 3 as an example. On the connection surface between the buoy 2 and the aquaculture net cage 3, the edge of the buoy 2 can be located at the edge of the aquaculture net cage 3, so that the upper surface of the buoy 2 can form a platform. When the aquaculture net cage 3 is inspected and repaired, the staff can step on the upper surface of the buoy 2 to move. In addition, the positioning member 5 can be a multi-section telescopic steel pipe, and the reeling member 4 can be a fixed end connected to the steel pipe of the uppermost section of the aquaculture net cage 3, and the present disclosure does not limit this.

[0031] Specifically, Figures 1 to 3 As shown, the base 1 may also include a pile foundation 11 and a support seat 12, wherein, in the step of constructing the base 1 in the seabed 7 and fixing the positioning member 5 on the base 1, when the base 1 is constructed, a plurality of pile foundations 11 may be first nailed into the seabed 7 at intervals, and then the positioning member 5 may be fixedly connected to part of the support seats 12, and finally the support seats 12 may be connected one by one to the pile foundation 11. The support seat 12 may effectively support the aquaculture cage assembly, and the support seat 12 may be at least partially connected to the positioning member 5. By supporting the aquaculture cage assembly with the support seat 12 arranged on the pile foundation 11, the influence of the suction of the seabed 7 on the aquaculture cage assembly may be effectively reduced.

[0032] Furthermore, after the step of connecting the support seat 12 to the pile foundation 11 in a one-to-one correspondence, the construction method may also include grouting reinforcement between the support seat 12 and the pile foundation 11. Grouting can make the support seat 12 and the pile foundation 11 firmly connected, reducing the possibility of the support seat 12 connected to the positioning member 5 being separated from the pile foundation 11 due to strong sea waves.

[0033] In addition, when performing the construction step of nailing multiple pile foundations 11 at intervals in the seabed 7, the construction method may further include making the top surfaces of the multiple pile foundations 11 located on the same horizontal line. That is, in the process of nailing the pile foundations 11 into the seabed 7, the arrangement of the multiple pile foundations 11 may be leveled so that the upper ends of the multiple pile foundations 11 are located on the same plane. In this way, even if the seabed 7 is uneven, the position leveling of the pile foundations 11 may prevent the aquaculture cages 3 from tilting due to the unevenness of the seabed, thereby enabling the aquaculture system to adapt to the seabed 7 of different terrains without filling the seabed 7, thereby improving the adaptability of the aquaculture system.

[0034] According to an embodiment of the present disclosure, Figures 1 to 6 As shown, the support seat 12 includes a first support seat 121 connected to the pile foundations 11 at both ends of the base 1 and a second support seat 122 connected to the pile foundations 11 in the middle section of the base 1, wherein, in the step of fixing the positioning member 5 to part of the support seat 12, the construction method may include the step of connecting the positioning member 5 to the second support seat 122. In this way, there is no need to set up an additional structure that cooperates with the positioning member 5, and only the support seat 12 on the pile foundation 11 that supports the aquaculture cage 3 and the pontoon 2 is required. In this way, the support seat 12 can not only provide support for the pontoon 2 and the aquaculture cage 3, but also cooperate with the positioning member 5 to reduce additional components in the aquaculture system and reduce costs. The number of positioning members 5 can be less than the number of support seats 12 to complete the positioning, and there is no need to connect all support seats 12 to the positioning member 5, which also reduces the construction time when the aquaculture system is constructed. The second support seats 122 may be arranged in a one-to-one correspondence with the positioning members 5 , or one positioning member 5 may correspond to multiple second support seats 122 or multiple positioning members 5 may correspond to one second support seat 122 , and the present disclosure does not make any limitation on this.

[0035] The second support seat 122 here may also include a positioning nail 1221 and a support plate 1222. The positioning nail 1221 can be fixedly connected to the pile foundation 11, and the support plate 1222 is arranged above the positioning nail 1221 to support the pontoon 2 and the aquaculture cage 3 on the pontoon 2. The positioning member 5 passes through the support plate 1222 and is connected to the positioning nail 1221. In this way, the connection part of the positioning member 5 and the second support seat 122 is located in the positioning nail 1221, which will not affect the shape of the support plate 1222, and thus will not affect the support of the aquaculture cage 3 by the support plate 1222. The first support seat 121 may also be a structure in which the positioning nail and the support plate cooperate, which is not limited in the present disclosure. If necessary, a shear key may be arranged on the positioning nail 1221 to improve the connection between the support seat 12 and the pile foundation 11. The support plate 1222 may be made of a steel plate or a reinforced concrete prefabricated plate, and a hanging point may be arranged on the support plate 1222 for installation. Considering that the aquaculture cage 3 needs to have the ability to resist lateral slippage under the action of ocean currents, grooves or concave-convex points can be added to the support plate 1222 and the area where the bottom of the pontoon 2 contacts the support plate 1222 to increase the friction coefficient between the support plate 1222 and the pontoon 2.

[0036] According to one embodiment of the present disclosure, Figures 1 to 6As shown, the aquaculture cage assembly may further include a pontoon 2 and a pontoon 3. A first accommodating chamber 20 for accommodating liquid may be formed inside the pontoon 2. The first accommodating chamber 20 may be openably connected to the outside for placing or discharging liquid, and may enable the pontoon 2 to move in the height direction. When manufacturing the aquaculture cage assembly and movably placing the aquaculture cage assembly above the base 1, the construction method may further include placing the pontoon 2 on the base 1, and fixedly connecting the aquaculture cage 3 above the pontoon 2. The buoyancy and sinking of the aquaculture cage assembly are controlled by the water storage and drainage of the buoyancy box 2. When the aquaculture system is installed on the seabed 7, the base 1 is first set up, and the positioning member 5 is connected to the base 1. After the aquaculture cage 3 is set on the buoyancy box 2, the positioning member 5 passes through the buoyancy box 2 and the aquaculture cage 3 and is connected to the reeling member 4 on the aquaculture cage 3. At this time, water is added to the buoyancy box 2 so that the buoyancy box 2 drives the aquaculture cage 3 to sink, and the reeling member 4 reels the positioning member 5 so that the descending speed of the aquaculture cage 3 and the reeling member 4 is consistent until the buoyancy box 2 sinks to the seabed 7 and sits on the base 1. When the buoyancy box 2 sits on the base 1, the upper edge of the aquaculture cage 3 and the reeling member 4 are both above the sea level. When the aquaculture cage 3 or the buoyancy box 2 needs to be repaired or the seafood is harvested, the buoyancy box 2 is drained so that the buoyancy box 2 drives the aquaculture cage 3 to float up, and the reeling member 4 releases the positioning member 5 until the upper surface of the buoyancy box 2 is exposed to the sea level 8, so as to carry out the repair and harvesting work.

[0037] Here, if Figure 5 As shown, the pontoon 2 may also include two pontoon bodies 201 and a plurality of cross bars 21. The two pontoon bodies 201 may be arranged at intervals on both sides of the width direction of the aquaculture cage 3 and extend along the length direction of the aquaculture cage 3. There are two bases 1, which are respectively arranged corresponding to the two pontoon bodies 201. The two ends of the cross bar 21 are respectively connected to the two pontoon bodies 201, and the plurality of cross bars 21 are arranged at intervals. In this way, the base 1 can support the pontoon 2 from both sides to improve the flatness of the bottom of the aquaculture cage 3.

[0038] Furthermore, if Figures 1 to 4As shown, the aquaculture cage 3 may also include a column 31, a support frame 32, a side net 33 and a bottom net. The material of the column 31 may be steel or reinforced concrete, which is not limited in the present disclosure. A second accommodating chamber 310 for accommodating liquid is formed inside the column 31. When making the aquaculture cage 3, a plurality of columns 31 may be arranged at intervals on the pontoon 2, and then the support frame 32 may be connected between two adjacent columns 31. When the columns 31 and the support frame 32 are arranged, the bottom net is connected between the bottom of the support frame 32 and the bottom of the column 31. After the bottom net is installed, the side net 33 is connected to the support frame 32, and the side net 33 is surrounded to form the side wall of the aquaculture cage 3. Here, a plurality of columns 31 may be connected at intervals above the pontoon 2 and extend in a direction away from the pontoon 2. A second accommodating chamber 310 for accommodating liquid is formed inside the column 31, and the second accommodating chamber 310 may be opened and closed to communicate with the outside. The two ends of the support frame 32 can be connected to two adjacent columns 31. The bottom net and the side net 33 can be a one-piece structure or a multi-piece spliced ​​structure. The bottom net and the side net 33 can be an ultra-molecular weight polyethylene net or a metal net, which is not limited in the present disclosure. When the bottom net and the side net 33 are ultra-molecular weight polyethylene nets, they can be connected to the columns 31 or the support frame 32 by tying. When the bottom net and the side net 33 are metal nets, they can also be connected by welding or bolts. The present disclosure also does not limit this. The top of the breeding net box 3 can be provided with an openable and closable top net to prevent sea birds from entering and stealing fish. The top of the breeding net box 3 can also be provided with a fixed platform according to the number and position of the positioning member 5, and the reel 4 can be provided on the fixed platform. It should be noted that when a plurality of breeding net boxes 3 need to be arranged side by side, two adjacent breeding net boxes 3 can also share the column 31 between them, which is not limited in the present disclosure.

[0039] Further, when constructing the column 31, if Figure 4As shown, the construction method also includes setting a water transport pipeline 6 in the column 31, and connecting it to the first accommodating chamber 20 and the second accommodating chamber 310 respectively. That is, the water transport pipeline 6 can be routed in the column 31, and here, the water transport pipeline 6 can include an inlet pipeline and an outlet pipeline, and the inlet and outlet water of the first accommodating chamber 20 and the second accommodating chamber 310 are independently connected, and the water flow between the first accommodating chamber 20 and the second accommodating chamber 310 is not connected. Multiple water transport pipelines 6 can enter from the top of the column 31 to connect the first accommodating chamber 20 and the second accommodating chamber 310 respectively inside, so as to more accurately adjust the amount of water in the first accommodating chamber 20 and the second accommodating chamber 310, thereby making precise adjustments to the settlement of the buoy 2 and the aquaculture cage 3. In summary of the process of setting the column 31, the column 31 may also include a first section 311 and a second section 312, the first section 311 is connected to the pontoon 2, the second accommodating chamber 310 is located in the first section 311, and the second section 312 is arranged above the first section 311, wherein the diameter of the first section 311 is greater than the diameter of the second section 312. In this way, it can be ensured that the column 31 can provide the same buoyancy and ballast effect as the pontoon 2, and the material consumption of the column 31 can be reduced, thereby reducing the cost.

[0040] Furthermore, during the construction of the column 31 and the pontoon 2, the first accommodating chamber 20 and the second accommodating chamber 310 can be divided into a plurality of mutually isolated ballast tanks, and then the water transport pipeline 6 is respectively connected to the ballast tanks of the first accommodating chamber 20 and the ballast tanks of the second accommodating chamber 310 to independently carry out water inlet and outlet to different ballast tanks. In this way, when a single ballast tank is damaged, the remaining ballast tanks can continue to function, thereby improving the fault tolerance of the aquaculture system. In addition, in order to improve the efficiency of water inlet and outlet, water pumps can be connected to both the water inlet and outlet pipelines, and the present disclosure does not limit this.

[0041] According to one embodiment of the present disclosure, Figures 1 to 4 As shown, in the construction process of the aquaculture cage 3, a plurality of vertical struts can be arranged at intervals on the pontoon 2. After the vertical struts are arranged, a plurality of horizontal struts 321 can be arranged at intervals between two adjacent columns 31, and the horizontal struts 321 and the vertical struts are arranged in an interlaced manner to form a plurality of lattice frames. Finally, a plurality of side nets 33 are connected to the vertical struts and the horizontal struts, and are arranged one by one in the lattice frames. In this way, the side nets 33 can be respectively arranged in the plurality of lattice frames formed by the horizontal struts 321 and the vertical struts, which can not only ensure the closed function of the aquaculture cage 3 and prevent the escape of seafood, but also the arrangement of multiple side nets 33 can reduce the possibility of deformation of the side nets 33. In addition, when the side nets 33 need to be replaced, only a portion of the side nets 33 can be replaced according to the damage and dirtiness of the side nets 33 at different positions, thereby reducing maintenance time and cost.

[0042] Furthermore, if Figures 1 to 4As shown, the buoyancy box 2 includes a through hole 22 isolated from the first accommodating chamber 20, and the vertical support rod includes a first support rod 322 and a second support rod 323. The second support rod 323 is a hollow rod. During construction, the hollow rod can be first set above the through hole 22, and finally the positioning member 5 is connected to the winding member 4 through the through hole 22 and the hollow rod in sequence. The hollow rod can improve the positioning effect and further prevent the misalignment of the aquaculture cage 3 during the floating and sinking process. The hollow rod can be a steel pipe, or other metal pipes or polymer pipes, which is not limited in the present disclosure. The winding member 4 is a winch, and the positioning member 5 is a steel wire rope, and the winch and the steel wire rope are both multiple and one-to-one corresponding. The steel wire rope and the hollow rod can also be set one-to-one. Specifically, two hollow rods can be arranged above each base 1 at intervals to further improve the positioning effect of the buoyancy box 2 and the aquaculture cage 3 during the floating and sinking process to prevent the two from running around.
