Description

Technical Field

[0001] This application relates to the technical field of tidal flat photovoltaic supports, and particularly relates to a large-span photovoltaic steel truss structure. Background Art

[0002] Fishery-photovoltaic complementary combines fishery farming and photovoltaic power generation in coastal tidal flats or fish ponds. Photovoltaic modules that can convert solar energy are arranged above the water area of the tidal flats or fish ponds to form a photovoltaic panel array that can cover the tidal flats or fish ponds. While the photovoltaic modules are performing normal photovoltaic power generation, they can also protect the fish underwater from wind and rain. Constructing a photovoltaic power generation project in the tidal flats is in response to the country's call for carbon neutrality and the need to accelerate the adjustment of the energy and power structure, and has gradually been applied in the tidal flats.

[0003] In the construction of a tidal flat photovoltaic project, it is usually necessary to first install suction piles on the tidal flat and then install a steel truss on the suction piles. A keel frame is fixed on the steel truss, and the photovoltaic modules can be installed on the keel frame by bolts or other means. When constructing a photovoltaic project in a tidal flat or fish pond, facing harsh wind conditions, the steel truss needs to bear a large wind pressure. To improve the stability of the steel truss, the distance between adjacent suction piles is set relatively close. However, fishing boats are also needed for feeding, net casting and other operations in the fish pond or tidal flat, and the small distance between the suction piles will make it inconvenient for the fishing boats to operate. Summary of the Invention

[0004] In order to provide sufficient operating space for fishing boats and maintain the stability of the support for photovoltaic modules, this application provides a large-span photovoltaic steel truss structure.

[0005] This application adopts the following technical solutions:

[0006] A large-span photovoltaic steel truss structure includes a support part and a frame part arranged on the support part; the support part includes a plurality of support beams, a connection part connected to both ends of the support beam and installed on the suction pile, and a reinforcement beam connected between adjacent two of the support beams; a plurality of connection nodes are installed at intervals along the length direction of the support beam, a reinforcing rod is connected between two adjacent connection nodes on the same support beam, and the reinforcement beam is also connected to the connection node.

[0007] By adopting the above technical solution, the support beams are connected between the suction piles, the support beams are connected by the reinforcement beams, connection nodes are also installed on the support beams, strengthening bars are connected between two adjacent connection nodes on the support beams, and the reinforcement beams are also connected to the connection nodes, so that the reinforcement beams and the strengthening bars form a network-like cross-linked structure, improving the stability of the overall support structure. When the frame part is installed on the support part, the support part is not easily bent downward under the action of the strengthening bars, enabling the support beams to have a greater span, and the distance between adjacent suction piles can also be set larger, thereby providing a larger working space for fishing boats.

[0008] Optionally, the connection node includes a positioning ring installed on the support beam and a socket tube connected to the positioning ring. The end of the reinforcement beam is slidably inserted into the socket tube, and a first shock absorber is installed in the socket tube, and the end of the reinforcement beam abuts against the first shock absorber.

[0009] By adopting the above technical solution, the reinforcement beam is slidably inserted into the socket tube and abuts against the first shock absorber. When the photovoltaic module is impacted by the wind, the force received by the photovoltaic module can be transmitted to the support beam, causing the support beam to swing. While the support beam is swinging, the reinforcement beam can slide relative to the socket tube, and the first shock absorber is used for shock absorption, thereby further improving the stability of the steel truss structure.

[0010] Optionally, the first shock absorber includes a sliding column slidably installed in the socket tube, first damping pads connected to both ends of the sliding column, and a first elastic member connected between the first damping pads and the reinforcement beam.

[0011] By adopting the above technical solution, the first shock absorber includes the first damping pads and the first elastic member connected between the sliding column and the reinforcement beam. When the sliding column and the reinforcement beam slide relative to each other in the socket tube, the first elastic member is compressed, and the first damping pads absorb energy. Then, the elastic force after the first elastic member is compressed can be used to drive the sliding column and the reinforcement beam to reset.

[0012] Optionally, a guiding groove is formed on the outer wall of the socket tube, and a guiding post extending into the guiding groove is arranged on the outer wall of the sliding column.

[0013] By adopting the above technical solution, the guiding post extends into the guiding groove. When the sliding column slides, the guiding post can slide in the guiding groove, and under the limiting action of the guiding post and the guiding groove, the sliding displacement of the sliding column can be restricted, reducing the situation where the sliding column slides out of the socket tube.

[0014] Optionally, the connection node further includes a positioning cylinder, which is arranged crosswise with the insertion cylinder, and the positioning cylinder and the insertion cylinder are communicated with each other; the end of the reinforcing rod is inserted into the positioning cylinder, and a second shock absorber is installed in the positioning cylinder. When the sliding column slides in the insertion cylinder, the second shock absorber can be compressed.

[0015] By adopting the above technical solution, the second shock absorber abuts against the sliding column. When the sliding column slides in the insertion cylinder due to the swing of the support beam, the second shock absorber can be compressed internally, so that the second shock absorber can transfer part of the force of the sliding column and improve the shock absorption effect when the sliding column slides.

[0016] Optionally, the second shock absorber includes a contact column slidably connected to the positioning cylinder, a second damping pad connected to the end of the reinforcing rod, and a second elastic member connected between the second damping pad and the contact column. An arc-shaped groove is formed on the outer wall of the sliding column, and one end of the contact column is a spherical structure and abuts in the arc-shaped groove.

[0017] By adopting the above technical solution, the end of the contact column is a spherical structure and abuts in the arc-shaped groove. When the sliding column slides, it can drive the contact column to slide away from the sliding column, and the second elastic member is compressed.

[0018] Optionally, the connecting portion includes a column installed on the suction pile and a positioning block connected to the end of the support beam. A positioning groove is formed on the column, and the positioning block is clamped in the positioning groove. A positioning member is connected to the column and passes through the column and the positioning block.

[0019] By adopting the above technical solution, the positioning block is clamped in the positioning groove, and the positioning member passes through the column and the positioning block, so that the positioning block is not easily detached from the positioning groove, thereby realizing the positioning of the support beam.

[0020] Optionally, the support beam is an arc-shaped structure with the arc opening facing downwards.

[0021] By adopting the above technical solution, the support beam is an arc-shaped structure, so that there is more space below the support beam, thereby providing a larger working space for the fishing boat.

[0022] Optionally, a contact block is connected to the outer wall of the support beam. When the positioning block is clamped in the positioning groove, the contact block can abut against the side wall of the column.

[0023] By adopting the above technical solution, when the support beam is an arc-shaped structure and is installed on the column, the contact block can abut against the side wall of the column. After the photovoltaic module is installed on the frame portion, both ends of the support beam tend to tilt upwards, and the contact block can limit this part of the acting force.

[0024] Optionally, an extension plate is provided on the positioning block, and a reinforcing plate is connected to the extension plate, and the reinforcing plate is connected to the suction pile.

[0025] By adopting the above technical solution, the positioning block is connected through the extension plate and the reinforcing plate, so as to further position the positioning block and further improve the stability of the connection of the support beam.

[0026] In summary, the present application includes at least one of the following beneficial effects:

[0027] 1. The support beam has an arc-shaped structure, and the reinforcing beam and the strengthening rod are connected through the connection node, which can greatly improve the stability of the support beam after installation, so that the support beam can have a larger span, thereby providing a larger space for operations such as fishing boats.

[0028] 2. The positioning block is connected to the column, and the abutting block can abut against the side wall of the column, and the stability of the support beam after installation is further improved under the action of the abutting block. Description of the Drawings

Detailed Description of the Embodiment

[0035] The following is combined with the attachedFigures 1-5 Further details of this application will be described below.

[0036] An embodiment of this application discloses a long-span photovoltaic steel truss structure. Referring to Figure 1 , the steel truss structure includes a support part 2 and a frame part 1 installed on the support part 2. The photovoltaic modules are installed on the frame part 1 by means of bolt assemblies and the like.

[0037] Combined with Figure 2 , the support part 2 includes a plurality of support beams 21, connection parts 22 installed at both ends of the support beams 21, and reinforcement beams 23 connected between two adjacent support beams 21. The support beams 21 are parallel to each other, and a plurality of reinforcement beams 23 are installed between two adjacent support beams 21. The reinforcement beams 23 are distributed at intervals along the length direction of the support beams 21. The support beams 21 are installed on the suction piles through the connection parts 22, so that each support beam 21 is connected between two suction piles. Connection nodes 3 are also installed on the support beams 21. A plurality of connection nodes 3 are arranged at intervals along the length direction of the support beams 21, and a strengthening rod 19 is installed between two adjacent connection nodes 3 on each support beam 21. Under the strengthening effect of the strengthening rod 19, the frame part 1 and the photovoltaic modules are installed on the support beams 21, and the support beams 21 are not easily compressed and bent downward. Further, the ends of the reinforcement beams 23 are also connected to the connection nodes 3, so that the strengthening rod 19 and the reinforcement beams 23 can form a cross-linked network structure, further improving the stability of the support part 2. Furthermore, while the support beams 21 have a greater span, they also have stability.

[0038] Referring to Figure 1 and Figure 2 , the frame part 1 includes a plurality of welding rods 16 welded to the support beams 21. A plurality of welding rods 16 are welded to each support beam 21. The welding rods 16 can be made of materials such as steel pipes, and the welding rods 16 are all welded to the same long beam 18. A plurality of cross beams 17 perpendicular to the long beam 18 are welded to the long beam 18. The cross beams 17 and the long beam 18 can form a dragon skeleton-like structure, and the photovoltaic modules can be installed on the dragon skeleton. In order to improve the light receiving rate of the photovoltaic modules, the dragon skeleton is arranged at a certain inclination angle.

[0039] In a further embodiment, referring to Figure 2 and Figure 3 , the connection node 3 includes a positioning ring 31 fixed to the support beam 21 and a plug-in cylinder 32 connected to the positioning ring 31. The positioning ring 31 is welded to the outer wall of the support beam 21. Since the support beam 21 can be set to have a relatively large span, the support beam 21 is welded together end to end by a plurality of steel pipes and the like, so as to obtain a support beam 21 with a sufficient length. The positioning ring 31 is preferably fixed at the position of the welding point on the support beam 21, so that the positioning ring 31 wraps the covering point on the support beam 21.

[0040] The insertion cylinder 32 has a hollow internal structure, and the end of the reinforcing beam 23 is slidably inserted into the insertion cylinder 32. A first shock absorber 4 is also installed in the insertion cylinder 32, and the reinforcing beam 23 can abut against the first shock absorber 4. When the support beam 21 swings under the action of external forces such as wind, the reinforcing beam 23 can slide relative to the insertion cylinder 32, and vibration isolation is achieved through the first shock absorber 4. In a further embodiment, the first shock absorber 4 includes a sliding column 41 slidably installed in the insertion cylinder 32, first damping pads 42 bonded to both ends of the sliding column 41, and a first elastic member 43 installed between the first damping pads 42 and the end of the reinforcing beam 23. The first damping pad 42 is made of rubber material with a certain elasticity, and the first elastic member 43 is preferably a damping spring. When the support beam 21 swings, it drives the reinforcing beam 23 to slide in the insertion cylinder 32, thereby achieving shock absorption through the first shock absorber 4. The length of the part of the reinforcing beam 23 inserted into the insertion cylinder 32 is sufficient, so that when the reinforcing beam 23 slides relative to the insertion cylinder 32, the reinforcing beam 23 cannot be disengaged from the insertion cylinder 32.

[0041] Furthermore, a guiding groove 5 is formed on the outer wall of the insertion cylinder 32, and the guiding groove 5 extends along the length direction parallel to the insertion cylinder 32. A guiding post 6 is fixed on the outer wall of the sliding column 41, and the guiding post 6 passes through the guiding groove 5 and is fixedly connected to the outer wall of the sliding column 41 by means of threaded connection, insertion, etc. When the sliding column 41 slides, the guiding post 6 can slide in the guiding groove 5, so that the guiding post 6 and the guiding groove 5 can limit the sliding distance of the sliding column 41, reducing the situation where the sliding column 41 slides out of the insertion cylinder 32.

[0042] In a further embodiment, referring to Figure 3 and Figure 4 , the support beam 21 is of an arc-shaped structure, and after the support beam 21 is installed, the opening of the support beam 21 faces downward, so that there is a larger space below the support beam 21 for operations such as fishing boats. The strengthening rod 19 is also of an arc-shaped structure, and the strengthening rod 19 and the support beam 21 are concentrically arranged. The connection node 3 further includes a positioning cylinder 33, the positioning cylinder 33 and the insertion cylinder 32 are cross-arranged, the positioning cylinder 33 is a hollow structure and the inner cavities of the positioning cylinder 33 and the insertion cylinder 32 are connected. The positioning cylinder 33 is also of an arc-shaped structure, and the end of the strengthening rod 19 is slidably inserted into the positioning cylinder 33, and the positioning cylinder 33 has a sufficient length, so that the strengthening rod 19 cannot be disengaged from the positioning cylinder 33.

[0043] A second shock-absorbing member 7 is also installed in the positioning cylinder 33. When the sliding column 41 slides in the plug-in cylinder 32, the second shock-absorbing member 7 can be compressed. The second shock-absorbing member 7 includes an abutting column 71 slidably connected to the positioning cylinder 33, a second damping pad 73 bonded to the end of the reinforcing rod 19, and a second elastic member 72 connected between the second damping pad 73 and the abutting column 71. The second elastic member 72 is preferably a shock-absorbing spring. An arc groove 8 is provided on the outer wall of the sliding column 41. The end of the abutting column 71 close to the sliding column 41 is a spherical structure, and the end of the abutting column 71 can abut in the arc groove 8. When the sliding column 41 slides, the abutting column 71 can be pressed by the sliding column 41 and slide in a direction away from the sliding column 41, so that the second elastic member 72 is compressed, so that the sliding force of the sliding column 41 can be partially transferred to the second shock-absorbing member 7 for consumption.

[0044] In a further embodiment, referring to Figure 1 and Figure 5 The connecting part 22 includes a column 221 and a positioning block 222 fixed to the end of the support beam 21. The column 221 is welded to the upper end surface of the suction pile, and the positioning block 222 is welded to the end of the support beam 21. The cross-section of the support beam 21 is a circular structure, and the cross-section of the positioning block 222 is a square structure. A positioning groove 10 is provided at the upper end of the column 221, and the positioning block 222 can be clamped in the positioning groove 10 from top to bottom. Under the action of the positioning block 222, the support beam 21 is not easy to rotate. A positioning member 9 is also installed on the column 221, and the positioning member 9 is used to limit the positioning block 222 from detaching from the positioning groove 10. The positioning member 9 can be a bolt, which is threadedly connected to the side wall of the column 221 and can pass through the positioning block 222. In order to improve the positioning effect, a plurality of bolts can be provided.

[0045] Furthermore, in order to improve the stability of the support beam 21, an abutment block 11 is welded on the outer wall of the support beam 21, and the abutment block 11 is a block-shaped structure. When the positioning block 222 is inserted into the positioning groove 10 from top to bottom, the abutment block 11 can abut against the side wall of the column 221, thereby improving the stability of the support beam 21. Furthermore, a clamping groove 13 can be provided on the side wall of the column 221, and a limiting block 12 is fixed on the abutment block 11. The abutment block 11 can abut in the clamping groove 13, and the stability of the support beam 21 is further improved under the action of the limiting block 12. An inclined rod 20 is also welded on the side of the column 221 close to the support beam 21, and the other end of the inclined rod 20 is welded to the side wall of the support beam 21, and the end of the adjacent reinforcing rod 19 is welded to the side wall of the inclined rod 20, further improving the anti-deformation ability of the support beam 21.

[0046] In a further embodiment, an extension plate 14 is welded to the positioning block 222, and a reinforcement plate 15 is mounted on the extension plate 14 by means of bolts or the like. The reinforcement plate 15 is welded to the upper surface of the suction pile. The reinforcement plate 15 is first fixed to the suction pile, and after the positioning block 222 is positioned in the positioning groove 10, the extension plate 14 and the reinforcement plate 15 are connected together, thereby further improving the positioning effect of the positioning block 222 and thus improving the stability of the overall support portion 2.

[0047] The implementation principle of a large-span photovoltaic steel truss structure in an embodiment of the present application is as follows: The support beam 21 has an arc-shaped structure. The support beam 21 is strengthened by the strengthening rod 19, and adjacent support beams 21 are connected together by the reinforcement beam 23. Under the action of the reinforcement beam 23 and the strengthening rod 19, the stability of the arc-shaped support beam 21 is improved, so that the support beam 21 can have a large span and good stability, greatly increasing the space below the steel truss structure.

[0048] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby.
