Description

TECHNICAL FIELD

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

[0002] The key of deep-sea aquaculture lies in the aquaculture equipment, i.e. the aquaculture net cage. Currently, common aquaculture net cages include gravity type net cages, truss type net cages, aquaculture platforms, and aquaculture work ships. Among them, the mobile bottom-sitting aquaculture net cage is often applied to the sea area with a water depth of 15m~40m as an important type of net cage. The mobile bottom-sitting net cage has the advantages of movable position, stable bottom-sitting, and convenient net replacement. However, since the net cage needs to be bottom-sitting, the requirement for the seabed is also high, generally requiring a flat seabed with strong bearing capacity. Before the net cage is bottom-sitting, detailed seabed topography survey needs to be conducted. If the seabed is not flat, seabed flattening operation needs to be conducted. If the seabed is soft, seabed replacement needs to be conducted. This brings great difficulty to the adaptability and application promotion of the bottom-sitting net cage. In addition, when the net cover of the net cage needs to be replaced, the net cage needs to be floated to the sea surface for replacement, and then the net cage is bottom-sitting again. In the process of floating and sinking of the net cage, the original positioning is also easy to deviate. Therefore, when the seabed is flattened in the early stage, the deviation caused by the replacement of the net cover is also considered, which increases the workload in the early stage. SUMMARY

DETAILED DESCRIPTION

[0051] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0052] In the present disclosure, the orientation words such as "upper" and "lower" are defined with respect to the arrangement direction of the aquaculture system in actual use, and the orientation words such as "inner" and "outer" are defined with respect to the outline of the corresponding component. The purpose of using the terms "first", "second", and the like is to distinguish different components, and does not have sequentiality and importance. In addition, in the following description, when referring to the drawings, the same reference numerals in different drawings represent the same or similar elements, unless otherwise explained.

[0053] According to an embodiment of the present disclosure, as shown in Figures 1 to 6 A construction method of an aquaculture system for seabed is provided, including the following steps: firstly, constructing a base 1 in the seabed 7 and fixing a positioning member 5 to the base 1; secondly, manufacturing an aquaculture cage assembly and movably placing the aquaculture cage assembly above the base 1; then, setting a winding member 4 above the aquaculture cage assembly, and after the setting of the winding member 4 is completed, passing the end of the positioning member 5 away from the base 1 through the aquaculture cage assembly and movably connecting the end of the positioning member 5 with the winding member 4. In this way, since the positioning member 5 is arranged in 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, which can be a linear lifting mechanism or a float 2 as described below, and the present disclosure does not limit this.

[0054] Through the above technical solution, the base 1 is arranged in the seabed 7 to replace the filling work of the seabed 7, which can reduce the early operation time, and since the bottom of the aquaculture cage assembly is seated on the base 1, at this time the mud surface of the seabed 7 has no suction force on the bottom of the aquaculture cage assembly, the aquaculture cage assembly can be easily lifted, and the maintenance and harvesting efficiency is effectively improved. Since the positioning member 5 is arranged in the aquaculture cage assembly, it can not only play the role of a mooring chain when the lower part of the aquaculture cage assembly floats to the sea level 8, but also eliminate the setting of the mooring chain. At the same time, during the lifting of the aquaculture cage assembly, the extension direction of the aquaculture cage assembly along the positioning member 5 can be effectively ensured through the winding and unwinding of the winding member 4, so that the aquaculture cage assembly can still be seated on the base 1 when it is seated on the seabed 7 again, and will not be out of position.

[0055] When the aquaculture cage assembly is sinking, the winding member 4 simultaneously winds the positioning member 5, so that the descending speed of the aquaculture cage assembly and the winding member 4 remains 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, at this time the upper edge of the aquaculture cage assembly and the winding member 4 are all above the sea level. When the aquaculture cage assembly needs to be maintained or harvested, the aquaculture cage assembly is controlled to float up, and at the same time the winding member 4 unwinds the positioning member 5, until the lower part of the aquaculture cage assembly is exposed to the sea level 8, so that the maintenance and harvesting work can be carried out.

[0056] It should be noted that here, the winding member 4 can be a winch, and the positioning member 5 can be a steel wire rope. The winding member 4 can be arranged one-to-one with the positioning member 5, or one winding member 4 can correspond to multiple positioning members 5. The present disclosure does not limit this. In the one-to-one arrangement of the winding member 4 and the positioning member 5, multiple positioning members 5 can be arranged at intervals, and the corresponding winding members 4 are also arranged at intervals to improve the anchoring ability of the positioning member 5 and prevent the possibility of deviation during the rising and falling of the aquaculture net cage assembly in the process of the large sea waves. Taking the structure of the aquaculture net cage assembly including the buoy 2 and the aquaculture net cage 3 as an example, the edge of the buoy 2 can be located at the edge of the aquaculture net cage 3 on the connecting surface of the buoy 2 and the aquaculture net cage 3, so that a platform can be formed on the upper surface of the buoy 2. When the aquaculture net cage 3 is being repaired, the staff can step on the upper surface of the buoy 2 to move. In addition, the positioning member 5 can be a plurality of telescopic steel pipes, and the winding member 4 can be a fixed end connected to the steel pipe at the uppermost part of the aquaculture net cage 3. The present disclosure does not limit this.

[0057] Specifically, as shown in Figures 1 to 3 The base 1 can also include pile foundations 11 and support seats 12. In the step of constructing the base 1 in the seabed 7 and fixedly connecting the positioning member 5 to the base 1, the base 1 can be constructed by first spacing a plurality of pile foundations 11 in the seabed 7, then fixedly connecting the positioning member 5 to part of the support seats 12, and finally connecting the support seats 12 one-to-one to the pile foundations 11. The support seats 12 can effectively support the aquaculture net cage assembly, and the support seats 12 can be at least partially connected to the positioning member 5. By supporting the aquaculture net cage assembly with the support seats 12 arranged on the pile foundations 11, the influence of the suction force of the seabed 7 on the aquaculture net cage assembly can be effectively reduced.

[0058] Further, after the step of connecting the support seats 12 one-to-one to the pile foundations 11, the construction method can also include grouting and reinforcing between the support seats 12 and the pile foundations 11. By grouting, the support seats 12 and the pile foundations 11 can be firmly connected, reducing the possibility of the support seats 12 connected to the positioning member 5 being separated from the pile foundations 11 due to too large sea waves.

[0059] In addition, in the construction step of spacing a plurality of pile foundations 11 in the seabed 7, the construction method can also include making the top surfaces of the plurality of pile foundations 11 lie on the same horizontal line. That is, during the process of driving the pile foundations 11 into the seabed 7, the positions of the plurality of pile foundations 11 can be leveled so that the upper ends of the plurality of pile foundations 11 lie on the same plane. In this way, even if the seabed 7 is not flat, the aquaculture net cage 3 will not tilt with the seabed, so that the aquaculture system can adapt to different seabed topographies without the need for filling the seabed 7, thereby improving the adaptability of the aquaculture system.

[0060] According to an embodiment of the present disclosure, as shown in Figures 1 to 6 The support seat 12 includes a first support seat 121 connected with the pile 11 at both ends of the base 1 and a second support seat 122 connected with the pile 11 at the middle section of the base 1. In the step of fixing the positioning member 5 to the partial support seat 12, the construction method can include the step of connecting the positioning member 5 to the second support seat 122. In this way, the structure matched with the positioning member 5 can be provided without additional structure, and the support seat 12 on the pile 11 can be used to support the net cage 3 and the buoy 2, so that the support seat 12 can provide support for the buoy 2 and the net cage 3 and can be matched with the positioning member 5 to reduce the additional components in the aquaculture system and reduce the cost. The number of the positioning member 5 can be less than the number of the support seat 12 to complete the positioning, and all the support seats 12 do not need to be connected with the positioning member 5, which also reduces the construction time of the aquaculture system. The second support seat 122 can be provided one by one with the positioning member 5, or one positioning member 5 can correspond to multiple second support seats 122, or multiple positioning members 5 can correspond to one second support seat 122, which is not limited in the present disclosure.

[0061] The second support seat 122 can also include a positioning nail 1221 and a support plate 1222. The positioning nail 1221 can be fixedly connected with the pile 11, and the support plate 1222 is arranged above the positioning nail 1221 to support the buoy 2 and the net cage 3 on the buoy 2, and the positioning member 5 is connected with the positioning nail 1221 through the support plate 1222. 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 does not affect the shape of the support plate 1222, and thus does not affect the support of the support plate 1222 to the net cage 3. The first support seat 121 can also be a structure matched with the positioning nail and the support plate, which is not limited in the present disclosure. If necessary, a shear key can be arranged on the positioning nail 1221 to improve the connection of the support seat 12 and the pile 11. The support plate 1222 can be made of a steel plate or a reinforced concrete prefabricated plate, and a lifting point can be arranged on the support plate 1222 for installation. Considering the need for the net cage 3 to have the ability to resist lateral sliding under the action of the sea current, grooves or concave-convex points can be added to the support plate 1222 and the area of the buoy 2 bottom in contact with the support plate 1222 to increase the friction coefficient between the support plate 1222 and the buoy 2.

[0062] According to an embodiment of the present disclosure, as shown in Figures 1 to 6As shown, the aquaculture cage assembly may also include a float 2 and an aquaculture cage 3. The interior of the float 2 may form a first receiving cavity 20 for containing liquid. The first receiving cavity 20 is openable and closable and communicates with the outside for placing or discharging liquid, enabling the float 2 to move along the height direction. When manufacturing the aquaculture cage assembly and movably placing the aquaculture cage assembly above the base 1, the construction method may also include placing the float 2 on the base 1 and fixing the aquaculture cage 3 above the float 2. The rising and sinking of the aquaculture cage components are controlled by the water storage and drainage of the pontoon 2. When installing the aquaculture system on the seabed 7, the base 1 is first set up, and the positioning component 5 is connected to the base 1. Then, the aquaculture cage 3 is placed on the pontoon 2, and the positioning component 5 is passed through the pontoon 2 and the aquaculture cage 3 and connected to the winding component 4 on the aquaculture cage 3. At this time, water is added to the pontoon 2 to make the pontoon 2 pull the aquaculture cage 3 to sink. At the same time, the winding component 4 winds up the positioning component 5 to keep the descent speed of the aquaculture cage 3 and the winding component 4 consistent until the pontoon 2 sinks to the seabed 7 and sits on the base 1. When the pontoon 2 sits on the base 1, the upper edge of the aquaculture cage 3 and the winding component 4 are above the sea level. When the aquaculture cage 3 or the pontoon 2 needs to be repaired or the seafood needs to be harvested, the pontoon 2 is drained to make the pontoon 2 pull the aquaculture cage 3 to float up. At the same time, the winding component 4 releases the positioning component 5 until the upper surface of the pontoon 2 is exposed above the sea level 8, so that the repair and harvesting work can be carried out.

[0063] Here, as Figure 5 As shown, the pontoon 2 may also include two pontoon bodies 201 and multiple crossbars 21. The two pontoon bodies 201 can 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 crossbars 21 are respectively connected to the two pontoon bodies 201, and the multiple crossbars 21 are arranged at intervals. In this way, the bases 1 can support the pontoon 2 from both sides, improving the flatness of the bottom of the aquaculture cage 3.

[0064] Furthermore, such as Figures 1 to 4As shown, the culture net cage 3 can also include a stand column 31, a support frame 32, a side net 33 and a bottom net. The stand column 31 can be made of steel or reinforced concrete, which is not limited in the present disclosure. The stand column 31 has a second accommodating cavity 310 for accommodating liquid. When the culture net cage 3 is made, a plurality of stand columns 31 can be arranged on the floating box 2 at intervals, and then the support frame 32 is connected between two adjacent stand columns 31. After the stand column 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 stand column 31. After the bottom net is installed, the side net 33 is connected to the support frame 32 to form the side wall of the culture net cage 3. Here, the plurality of stand columns 31 can be connected at intervals above the floating box 2 and extend away from the floating box 2. The stand column 31 has a second accommodating cavity 310 for accommodating liquid, which can be opened and closed to communicate with the outside. The two ends of the support frame 32 can be connected to two adjacent stand 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 a super 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 a super molecular weight polyethylene net, they can be connected to the stand column 31 or the support frame 32 by binding. When the bottom net and the side net 33 are a metal net, they can also be connected by welding or bolting, which is also not limited in the present disclosure. The top of the culture net cage 3 can be provided with an openable top net to prevent seabirds from entering and stealing fish. The top of the culture net cage 3 can also be provided with a fixed platform according to the number and position of the positioning member 5, and the winding member 4 can be arranged on the fixed platform. It should be noted that when the culture net cage 3 needs to be arranged side by side, two adjacent culture net cages 3 can share the stand column 31 therebetween, which is not limited in the present disclosure.

[0065] Further, when the stand column 31 is constructed, as shown in FIG. 6, the stand column 31 can be arranged on the floating box 2 at intervals, and then the support frame 32 is connected between two adjacent stand columns 31. After the stand column 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 stand column 31. After the bottom net is installed, the side net 33 is connected to the support frame 32 to form the side wall of the culture net cage 3. Here, the plurality of stand columns 31 can be connected at intervals above the floating box 2 and extend away from the floating box 2. The stand column 31 has a second accommodating cavity 310 for accommodating liquid, which can be opened and closed to communicate with the outside. The two ends of the support frame 32 can be connected to two adjacent stand 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 a super 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 a super molecular weight polyethylene net, they can be connected to the stand column 31 or the support frame 32 by binding. When the bottom net and the side net 33 are a metal net, they can also be connected by welding or bolting, which is also not limited in the present disclosure. The top of the culture net cage 3 can be provided with an openable top net to prevent seabirds from entering and stealing fish. The top of the culture net cage 3 can also be provided with a fixed platform according to the number and position of the positioning member 5, and the winding member 4 can be arranged on the fixed platform. It should be noted that when the culture net cage 3 needs to be arranged side by side, two adjacent culture net cages 3 can share the stand column 31 therebetween, which is not limited in the present disclosure. Figure 4As shown, the construction method further comprises arranging the water pipelines 6 in the columns 31 and connecting the water pipelines 6 with the first accommodating cavities 20 and the second accommodating cavities 310 respectively. That is, the water pipelines 6 can be arranged in the columns 31, and here, the water pipelines 6 can comprise water inlet pipelines and water outlet pipelines, and the water inlets and outlets of the first accommodating cavities 20 and the second accommodating cavities 310 are independently connected, and the water flow between the first accommodating cavities 20 and the second accommodating cavities 310 is not communicated. The water pipelines 6 can all enter from the top of the columns 31 to be connected with the first accommodating cavities 20 and the second accommodating cavities 310 respectively, so as to more accurately adjust the water amount in the first accommodating cavities 20 and the second accommodating cavities 310, and thus accurately adjust the sinking of the floating box 2 and the culture net cage 3. During the arrangement of the columns 31, the columns 31 can also comprise a first section 311 and a second section 312, the first section 311 is connected with the floating box 2, the second accommodating cavities 310 are arranged 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 columns 31 can provide the same buoyancy and ballast effect as the floating box 2, and the material consumption of the columns 31 can be reduced, and the cost can be reduced.

[0066] Further, during the construction of the columns 31 and the floating box 2, the first accommodating cavities 20 and the second accommodating cavities 310 can all be divided into multiple mutually isolated ballast compartments, and then the water pipelines 6 are connected with the ballast compartments of the first accommodating cavities 20 and the ballast compartments of the second accommodating cavities 310 respectively, so as to independently control the water inlet and outlet of different ballast compartments. In this way, when a single ballast compartment is damaged, the remaining ballast compartments can continue to function, and the fault tolerance of the culture system is improved. In addition, in order to improve the water inlet and outlet efficiency, water pumps can be connected to the water inlet pipelines and the water outlet pipelines, and the present disclosure does not limit this.

[0067] According to an embodiment of the present disclosure, as shown in Figures 1 to 4 During the construction of the culture net cage 3, multiple vertical support rods can be arranged on the floating box 2 at intervals, and after the vertical support rods are arranged, multiple horizontal support rods 321 can be arranged between two adjacent columns 31 at intervals, and the horizontal support rods 321 and the vertical support rods are arranged alternately to form multiple lattice type frames, and finally the multiple side nets 33 are connected with the vertical support rods and the horizontal support rods and are arranged in the lattice type frames one by one. In this way, the side nets 33 can be arranged in multiple lattice type frames formed by the horizontal support rods 321 and the vertical support rods, which can not only ensure the sealing function of the culture net cage 3 and prevent marine products from escaping, but also reduce the possibility of deformation of the side nets 33. In addition, when the side nets 33 need to be replaced, only partial replacement can be performed according to the damage and dirt conditions of the side nets 33 at different positions, so as to reduce the maintenance time and cost.

[0068] Further, as shown in Figures 1 to 4As shown, the buoyancy tank 2 comprises a through hole 22 which is isolated from the first accommodating cavity 20, the vertical support rod comprises 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 arranged above the through hole 22, and finally the positioning member 5 is connected with the winding member 4 through the through hole 22 and the hollow rod in sequence. The hollow rod can improve the positioning effect, further prevent the misplacement of the culture net cage 3 during the process of floating and sinking, the hollow rod can be a steel pipe, or other metal pipe or polymer pipe, and the present disclosure does not make any limitation on this. The winding member 4 is a winch, 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 arrangement, and the steel wire rope and the hollow rod can also be one-to-one corresponding arrangement, specifically, two hollow rods can be arranged above each base 1 in sequence to further improve the positioning effect of the buoyancy tank 2 and the culture net cage 3 during the process of floating and sinking, and prevent the two from running around.

[0069] On the basis of the above-mentioned scheme, the present disclosure further provides a construction method of the culture system for the seabed culture system, which has all the beneficial effects of the culture system described above, and details are not repeated here.
