Description

Technical Field

[0001] The present invention belongs to the field of offshore new energy technology, and in particular relates to a multifunctional engineering support structure for use in tidal flat areas and an installation method thereof. Background Art

[0002] Tidal flats often utilize a fishery-solar hybrid system to maximize aquaculture and economic benefits. This system combines traditional fishery farming with photovoltaic power generation. Traditional tidal flat fishery-solar hybrid systems typically utilize fixed-mount structures, suitable for relatively calm waters and enabling the integration of photovoltaic power generation and fishery farming. However, this structure presents significant drawbacks in dynamic tidal flats subject to strong wave impact. Firstly, the boundaries of tidal flats are often jagged, curved, or segmented, making it difficult for fixed-mount systems to adapt to the continuous and irregular changes in these boundaries, resulting in the inability to flexibly adjust the aquaculture areas. Secondly, the foundations of fixed-mount systems (such as piles) in the soft soil of tidal flats are susceptible to uneven settlement or tilting due to hydrogeological changes (such as tidal erosion and sediment migration). This further exacerbates the mismatch between the structure and the actual boundary, compromising the long-term stability of the system. Strong wave impacts further destabilize the mounts and affect the aquaculture environment, limiting the application scope of such systems.

[0003] In existing technology, the high intensity and frequency of waves on tidal flats can affect the profitability of fish farming. Therefore, fishery-solar hybrid projects are generally located in areas with low wave impact and relatively calm waters. Wave power generation devices, on the other hand, are best deployed in areas with high intensity and frequency of surf impact to maximize their economic benefits. Consequently, wave power generation devices are often not effectively integrated with fishery-solar hybrid systems, resulting in low combined energy utilization rates in tidal flats. Summary of the Invention

[0004] The purpose of the present invention is to provide a multifunctional engineering support structure for tidal flat areas and its installation method, which solves the problems that the existing fish-photovoltaic complementary method is difficult to adapt to the continuous irregular changes in the boundary lines of the tidal flat area and the wave energy power generation is difficult to match the fish-photovoltaic complementary system.

[0022] Furthermore, a first connecting screw arranged in the vertical direction is connected between the upper end closing plate and the bottom plate of the U-shaped force-bearing part, and a second connecting screw arranged in the horizontal direction is connected between the two side end plates of the U-shaped force-bearing part.

[0028] Furthermore, breakwaters are scattered on the sides of the foundation pedestal and in areas where waves strike vertically.

[0029] The present invention also discloses a method for installing the multifunctional engineering support structure for use in a tidal flat area, comprising the following steps:

[0030] S1. Arrange and install all foundation pedestals along the shore or on the shore of the mudflat area, and install a truss structure on each foundation pedestal;

[0031] S2. Connect the cover plates at the ends of the truss structure, install multiple main load-bearing steel pipes between two adjacent cover plates, and install anti-torsion support parts on the outside of the main load-bearing steel pipes;

[0032] During the connection of the main load-bearing steel pipes, install the reversing part when reversal is required according to the on-site installation conditions;

[0033] S3. Install a U-shaped load-bearing part and an upper end closing plate on the outside of the main load-bearing steel pipe in the horizontal straight section;

[0034] S4. Install the photovoltaic panel on the upper closed plate and the wave energy power generation device on the box structure. The installation is now complete.

[0035] Compared with the prior art, the present invention has the following beneficial technical effects:

[0036] The present invention discloses a multifunctional engineering support structure for tidal flats. By setting a plurality of foundation pedestals on or near the shore of the tidal flat, each foundation pedestal is connected to a truss structure, thereby achieving an ultra-long continuous arrangement of main load-bearing steel pipes, effectively expanding the fish farming area and improving the overall farming efficiency of the tidal flat. Setting the foundation pedestals on or near the shore of the tidal flat can effectively reduce the settlement caused by hydrogeological changes and increase the service life. The main load-bearing steel pipes can be continuously set along or near the shore of the tidal flat, thereby coordinating the tidal flat area to obtain more fish farming area. Multiple anti-torsion support parts are provided on the outside of the main load-bearing steel pipes to strengthen the anti-torsion ability of the main load-bearing steel pipes and coordinate the stress of multiple main load-bearing steel pipes, allowing multiple main load-bearing steel pipes to bear stress together and avoid excessive local deformation of the main load-bearing steel pipes. A wave energy power generation device and a photovoltaic panel are installed on the box structure, and the box structure will be subjected to external forces. Therefore, anti-torsion support parts are provided on the outside of the main load-bearing steel pipes covered by the box structure to further ensure the overall stability of the box structure. The boundary line of the shore or on the shore of the mudflat area is generally jagged, curved or discontinuous in segments. The reversing part can also be used to control the distance between the main load-bearing steel pipe and the shore or on the mudflat area, and the distance between the main load-bearing steel pipe and the foundation pedestal can be controlled; and the wave energy power generation device and the main load-bearing steel pipe can be used to weaken the impact of waves on the fishery breeding area, which is beneficial to fishery breeding. Combining wave energy with the fish-light complementary system further improves the comprehensive benefits of traditional fish-light complementary.

[0037] Furthermore, the torsion-resistant support portion designed in the present invention includes a connecting ring and an X-shaped connecting plate. The X-shaped connecting plate is arranged in the middle of the four main load-bearing steel pipes, and the connecting ring is connected to the outside of the main load-bearing steel pipes. A first connecting end plate is arranged on the outside of the connecting ring toward the center point of the four main load-bearing steel pipes; a first U-shaped plate is arranged at the end of the X-shaped connecting plate, and the first U-shaped plate is bolted to the first connecting end plate. The connecting ring surrounds the four main load-bearing steel pipes to form an outer constraint, and the X-shaped connecting plate forms a cross support in the middle. The two together construct a three-dimensional spatial stability system. When the main load-bearing steel pipes are impacted by waves, the X-shaped connecting plate disperses the torque to each main load-bearing steel pipe through bolts to prevent a single main load-bearing steel pipe from being overstressed. The gap between the connecting ring and the main load-bearing steel pipes is filled with foam, plain concrete or rubber material, so that the connection between the connecting ring and the main load-bearing steel pipes is tighter. The anti-torsion support part can enhance the anti-torsion ability of the four main load-bearing steel pipes, and coordinate the forces of the four main load-bearing steel pipes, so that the four main load-bearing steel pipes bear the forces together, thereby avoiding excessive local deformation of the four main load-bearing steel pipes.

[0038] Furthermore, the present invention sets up breakwaters at both ends of the base and adopts a specific layout method, which effectively reduces the impact of waves on the cantilever rods, improves the stability of the cantilever rods in engineering scenarios, and thus increases the service life of the support structure; at the same time, it weakens the impact of waves on the fishery breeding area, which is beneficial to fishery breeding.

[0054] The features and performances of the present application are further described in detail in combination with the examples below.

[0055] Example one

[0056] As Figure 1 and Figure 2 As shown, the present invention discloses a multifunctional engineering support structure for tidal flat areas, including a plurality of base pedestals 1 arranged on or near the shore of the tidal flat area. The base pedestals 1 are concrete structures. The function of the base pedestals 1 is to fix the cantilever rods 2, and personnel can also stand on the base pedestals 1 to catch fish.

[0057] Compared with the traditional method of setting the support structure directly in the water, setting the foundation pedestal 1 on the shore or on the shore of the mudflat area can effectively reduce the settlement caused by hydrogeological changes.

[0058] The end face of the base pedestal 1 away from the land is connected to two cantilever rods 2, and multiple chord rods 21 are connected in the middle of the cantilever rods 2. The multiple chord rods 21 and the cantilever rods 2 can form a truss structure. The truss structure is lightweight and has extremely strong bearing capacity in the vertical plane, and is used to support all the main load-bearing steel pipes 7.

[0059] The other ends of the two cantilever members 2 are connected to the end connecting rod 23 , and the ends of the chord rods 21 between the two cantilever members 2 are connected to the inner connecting rod 24 , which is parallel to the end connecting rod 23 and spaced apart.

[0060] The chord 21 is connected to the transition area between the inner connecting rod 24 and the cantilever member 2 .

[0061] The base pedestal 1 and the cantilever rod 2 are regarded as a unit structure. When multiple unit structures are grouped together, end sealing plates 22 are provided between the inner connecting rods 24 and the end connecting rods 23 connected to the base pedestals 1 at both ends, and a middle sealing plate 29 is provided between the inner connecting rods 24 and the end connecting rods 23 connected to the middle base pedestal 1. Figure 1 Here, only three unit structures are used as examples.

[0062] In the present invention, all the middle sealing plates 29 and the middle parts of the end sealing plates 22 are commonly connected to four main load-bearing steel pipes 7, and the four main load-bearing steel pipes 7 are arranged in a matrix shape.

[0063] The structure of the middle sealing plate 29 and the end sealing plates 22 is the same, and only the method of connecting the main load-bearing steel pipe 7 is different.

[0064] like Figure 5 As shown, the main load-bearing steel pipe 7 is connected to the middle sealing plate 29 by means of the first flange 71. The ends of the main load-bearing steel pipe 7 are each provided with a first flange 71 and are installed on both sides of the middle sealing plate 29. Bolts are then used to connect the two first flanges 71 to the middle sealing plate 29, thereby realizing the connection between the two main load-bearing steel pipes 7 and the middle sealing plate 29.

[0065] like Figure 6As shown, the main load-bearing steel pipe 7 is connected to the end sealing plate 22 by means of a first flange 71 .

[0066] The first flange 71 is arranged on the outside of the main load-bearing steel pipe 7 , and the first flange 71 is welded to the contact boundary line of the main load-bearing steel pipe 7 .

[0067] like Figure 1 and Figure 2 As shown, a plurality of anti-torsion support parts 5 are provided on the four main stress-bearing steel pipes 7, which can enhance the anti-torsion ability of the four main stress-bearing steel pipes 7 and coordinate the stress of the four main stress-bearing steel pipes 7, so that the four main stress-bearing steel pipes 7 are stressed together, thereby avoiding excessive deformation of the four main stress-bearing steel pipes 7.

[0068] like Figure 7 As shown, a plurality of anti-torsion support parts 5 are provided on the four main load-bearing steel pipes 7. The anti-torsion support parts 5 include a connecting ring 72. The connecting ring 72 is connected to the outer side of the main load-bearing steel pipe 7. The connecting ring 72 is not directly fixed to the main load-bearing steel pipe 7. The gap between the connecting ring 72 and the main load-bearing steel pipe 7 is filled with foam, plain concrete or rubber material.

[0069] A first connecting end plate 73 is also provided on the outside of the connecting ring 72 toward the center point of the four main load-bearing steel pipes 7. An X-shaped connecting plate 75 is provided in the middle of the four main load-bearing steel pipes 7. A first U-shaped plate 74 is provided at the end of the X-shaped connecting plate 75. The first U-shaped plate 74 is bolted to the first connecting end plate 73.

[0070] More preferably, a plurality of stiffening ribs are provided in the middle of the X-shaped connecting plate 75 to enhance the torsional strength of the X-shaped connecting plate 75 .

[0071] The four main load-bearing steel pipes 7 in the present invention can be set to be extra long, and it is only necessary to further add the basic pedestal 1 on the shore or on the shore of the mudflat area.

[0072] like Figure 10As shown, a plurality of box structures are also provided on the outside of the four main load-bearing steel pipes 7. Each box structure includes a detachably connected U-shaped load-bearing portion 6 and an upper end closing plate 8. The U-shaped load-bearing portion 6 is a U-shaped structure, and two L-shaped plates 61 are provided in the middle of the U-shaped load-bearing portion 6. The upper end closing plate 8 is also a U-shaped structure. Two symmetrical L-grooves for clamping the L-shaped plates 61 are prefabricated on the upper end closing plate 8. When the U-shaped load-bearing portion 6 and the upper end closing plate 8 are spliced ​​together, the L-shaped plates 61 can just be embedded in the L-grooves to ensure that the two cannot slip, and the U-shaped load-bearing portion 6 and the upper end closing plate 8 can be firmly fixed on the outside of the four main load-bearing steel pipes 7. The U-shaped load-bearing portion 6 and the upper end closing plate 8 form a box structure as a whole, and at least two anti-torsion support portions 5 are provided inside the box structure, which provide support for the U-shaped load-bearing portion 6 and the upper end closing plate 8, and further strengthen the integrity and anti-torsion strength of the four main load-bearing steel pipes 7 in the corresponding area of ​​the U-shaped load-bearing portion 6.

[0073] Furthermore, a layer of rubber gasket is required to be provided on the outside of the connecting ring 72 in the anti-torsion support part 5 inside the box structure to provide buffering for the connecting ring 72, the U-shaped force-bearing part 6 and the upper end closing plate 8.

[0074] Furthermore, a first connecting screw 82 arranged in the vertical direction is connected between the upper end closing plate 8 and the bottom plate of the U-shaped force-bearing part 6, and a second connecting screw 81 arranged in the horizontal direction is connected between the two side end plates of the U-shaped force-bearing part 6. The first connecting screw 82 and the second connecting screw 81 connect the upper end closing plate 8 and the U-shaped force-bearing part 6 into one and are fixed to the outside of the four main force-bearing steel pipes 7. The second connecting screw 81 needs to be staggered with the anti-torsion support part 5.

[0075] Each main stress-bearing steel pipe 7 is composed of multiple sections of round steel pipes or multiple sections of double-circular steel pipe concrete composite structures. Specifically, the connection method of the multiple sections of round steel pipes or multiple sections of double-circular steel pipe concrete composite structures is flange connection. The sealing performance needs to be ensured during the flange connection to prevent seawater from entering the interior of the main stress-bearing steel pipe 7, thereby preventing the mass of the main stress-bearing steel pipe 7 from increasing and the buoyancy from decreasing.

[0076] like Figure 10 As shown, a connecting pipe section 31 is provided on the top surface of the upper end closing plate 8, and the connecting pipe section 31 is connected to the photovoltaic panel 3. A supporting structure is provided at the lower part of the photovoltaic panel 3, and the supporting structure is fixedly connected to the connecting pipe section 31. The supporting structure is a column structure or a grid structure.

[0077] like Figure 10As shown, the upper end closing plate 8 is connected to a wave energy power generation device, specifically: a main connecting rod 44 is provided on the end face of the U-shaped force-bearing part 6 away from the base pedestal 1, the main connecting rod 44 is hinged to the U-shaped force-bearing part 6, the main connecting rod 44 can only swing in the vertical plane, and the other end of the main connecting rod 4 is hinged to the floating plate 4, and the floating plate 4 is used to receive wave impact, that is, to obtain wave energy.

[0078] The floating plate 4 is a hollow disc-shaped structure and is made of a high-strength and corrosion-resistant rubber material.

[0079] A fixed section 41 is located above the upper closure plate 8 and is fixedly connected to the upper closure plate 8. This section 41 hinges onto a retractable power generation section 42, which is a hollow piston structure. One end of a telescopic connection section 43 can slide within this section. A generator is also housed within this section, and the other end of this connection section 43 is connected to the floating plate 4. The power generation principle is as follows: the cyclical motion of seawater (such as tides and waves) drives the reciprocating motion of the piston. A transmission mechanism connected to the piston converts this reciprocating motion into rotational motion or pressure energy. The generator, connected to the transmission mechanism, generates electricity through its rotational motion, cutting through magnetic flux lines, thereby converting the mechanical energy of the seawater into electrical energy.

[0080] Example 2

[0081] Since the shoreline of the tidal flat area is constantly changing and is not always straight, the connection of the main load-bearing steel pipe 7 cannot be guaranteed to be a straight connection all the time.

[0082] like Figure 3 and Figure 4 As shown, the difference from the first embodiment is that a plurality of reversing parts 9 are provided in the middle of the four main load-bearing steel pipes 7, such as Figure 8 and Figure 9 As shown, the reversing portion 9 includes two connecting folding plates 91, and a first rotating hinge 92 is provided at one end of the two connecting folding plates 91 close to each other. The two connecting folding plates 91 can rotate relative to each other around the first rotating hinge 92, and a second rotating hinge 93 is provided at the other end of the two connecting folding plates 91. An interactive connecting plate 95 is rotatably connected to the second rotating hinge 93. The two interactive connecting plates 95 are in contact with each other, and a connecting long groove 94 is prefabricated on the interactive connecting plate 95. The horizontal projections of the two connecting long grooves 94 can overlap. Sunken grooves are provided on both sides of the extension direction of the two connecting long grooves 94, and bolts are connected in the sunken grooves to ensure that the two interactive connecting plates 95 can be reliably connected and the connection of the two interactive connecting plates 95 is stable.

[0083] Each main load-bearing steel pipe 7 is connected to the connecting folded plate 91 through a second flange 96 .

[0084] like Figure 9As shown, the two reversing parts 9 can be matched to make the four main force steel pipes 7 turn, and the main force steel pipes 7 can be connected in succession through the reversing parts 9.

[0085] In the present application, the area between the two adjacent foundation pedestals 1 and the four main force steel pipes 7 can be matched with the beach area to arrange fish farming, and the fishing net can be directly hung on the main force steel pipes 7 and the cantilever bar 2, and the floating disc 4 can be matched with the main connecting rod 44, the telescopic connecting section 43 and the contraction power generation section 42 to generate wave energy. The absorbed wave energy can reduce the wave impact on the fish farming area, that is, the impact of the wave on the fish is weakened, which is beneficial to the fish farming.

[0086] The present application has the advantages that the main force steel pipes 7 can be arranged in succession for a long distance, so that more fish farming areas can be obtained in the beach area, and the distance between the main force steel pipes 7 and the shore can be changed, and the main force steel pipes 7 can provide a platform for photovoltaic power generation and wave energy generation.

[0087] The cantilever bar 2 matched with the chord 21 can make the truss structure have strong bending strength to bear the four main force steel pipes 7.

[0088] The foundation pedestal 1 is arranged on the shore or on the shore of the beach area, which can effectively reduce the settlement of the support structure of the present application caused by the change of hydrogeology.

[0089] More preferably, the side of the foundation pedestal 1 at both ends of the device also needs to be separately provided with a breakwater 10, but the breakwater 10 should not affect the normal use of the device, and the breakwater 10 is used to reduce the lateral force of the wave on the truss structure, so as to improve the service life of the whole structure.

[0090] As shown in Figure 11 The arrangement principle of the breakwater 10 is that the breakwater 10 is arranged on the side of the foundation pedestal 1 at both ends in parallel with the extension direction of the cantilever bar 2, and then converges to the direction of the floating disc 4 at a certain distance after the cantilever bar 2, and the breakwater 10 needs to be scattered in the area perpendicular to the wave impact (at a certain distance from the floating disc 4), so as to weaken the impact of the wave on the cantilever bar 2, thereby improving the service life of the device.

[0091] Of course, as described in the first embodiment, the foundation pedestal 1 and the cantilever bar 2 can be regarded as a unit structure, and a plurality of unit structures are arranged as a group, and the breakwater 10 is arranged on the side of the foundation pedestal 1 at both ends in parallel with the extension direction of the cantilever bar 2.

[0092] The installation steps of the multifunctional engineering support structure for the beach area of the present application are as follows:

[0093] S1. Arrange and install all foundation pedestals 1 along the shore or on the shore of the mudflat area, and install a cantilever rod 2 on each foundation pedestal 1;

[0094] S2. Install the end connecting rod 23, the inner connecting rod 24, the end sealing plate 22 and the middle sealing plate 29 in this order, and then connect the chord rod 21;

[0095] S3, install the main load-bearing steel pipe 7 and the anti-torsion support part 5 at the same time;

[0096] During the connection of the main load-bearing steel pipe 7, according to the on-site installation conditions, when reversal is required, the reversing part 9 is installed;

[0097] S4. Install the U-shaped load-bearing part 6 and the upper end closing plate 8 outside the main load-bearing steel pipe 7 in the horizontal straight section;

[0098] S5. Install the photovoltaic panel 3 on the upper end closing plate 8 and install the wave energy power generation device on the box structure. Now the installation of the multifunctional engineering support structure for the tidal flat area is completed.

[0099] Before S1 starts, at least the breakwaters 10 on both sides of the base pedestal 1 need to be arranged at predetermined positions. Wave impact is uncertain, so large waves are prevented from destroying the support structure under construction, so as to reduce the impact of waves on construction.
