Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to an enclosure plate structure and a photovoltaic widening platform system for a cooling tower. Background Art

[0002] A cooling tower extension is a horizontal extension structure installed on the exterior of the cooling tower. The extension is typically supported by trusses or steel frames and secured by welding or bolting. The outer casing is attached to the exterior of the tower or extension, forming a closed or semi-closed enclosure. For example, in a hyperbolic cooling tower, the outer casing and the extension trusses together form the outer contour of the tower.

[0003] The area around cooling towers is generally open and unobstructed. Currently, the protective panels of the cooling tower widening platform are often idle and not well utilized. If photovoltaic modules are installed on the protective panels, screws are needed to fix the photovoltaic module brackets to the protective panels. However, when the photovoltaic module brackets are installed on the cooling tower protective panels with screws, there are the following defects: the protective panels are usually non-load-bearing structures, and stress concentration points are easily formed at the screw installation points, causing deformation or cracking of the screw installation points of the protective panels; the screw connections are prone to slippage or loosening under dynamic loads (such as wind vibration and cooling tower vibration), affecting the stability of the photovoltaic brackets. Summary of the Invention

[0004] In view of this, the present invention provides a protective plate structure and a cooling tower photovoltaic widening platform system to solve the problem that the cooling tower protective plate is installed with photovoltaic component brackets by screws, which causes the screw installation points of the protective plate to be easily deformed or cracked.

[0005] In a first aspect, the present invention provides a protective plate structure, comprising:

[0006] The enclosure plate includes an enclosure plate body and at least one positioning protrusion integrally provided with the enclosure plate body, the positioning protrusion protruding outward along an outer wall of the enclosure plate body, the positioning protrusion having a positioning portion and a clamping cavity, the clamping cavity having an opening facing inward;

[0007] At least one support, the support having a clamping portion and a first mounting portion, the clamping portion being clamped and positioned in the clamping cavity, the first mounting portion and the clamping portion being located on either side of the opening so that the first mounting portion can be connected to a first positioning member located inside the enclosure body;

[0008] At least one clamp has a clamping portion and a second mounting portion, the clamping portion is adapted to the positioning portion and is clamped and positioned on the positioning protrusion, and the second mounting portion is suitable for positioning the second positioning member on the enclosure plate.

This completely avoids drilling holes or using screws in the enclosure panel body, and can achieve nail-free connection between widened platform roof panels, completely eliminating the stress concentration caused by screw installation. Since there is no need to drill holes in the enclosure panel or use screws to connect, deformation or cracking of the enclosure panel due to stress concentration is avoided, thereby improving the reliability of the enclosure panel roof.

[0010] The embedded matching design of the clamping cavity and the clamping part, combined with the clamping and fixing of the positioning part by the fixture, forms multiple anti-displacement constraints, effectively resisting dynamic loads such as wind vibration and cooling tower vibration, and avoiding slippage or relaxation.

[0011] In an optional embodiment, the snap-fitting cavity is arranged along the front-to-back direction, the snap-fitting portion slides along the front-to-back direction and is snap-fitted into the snap-fitting cavity and is limited left and right by the snap-fitting cavity; the clamping portion is a clamping groove, the clamping portion is arranged along the front-to-back direction, the clamping portion slides along the front-to-back direction and is snap-fitted to the outer side of the positioning portion and is limited left and right by the positioning portion.

[0016] The beneficial effects of the above technical solution are: the first positioning portion, the second positioning portion, the first snap-fitting cavity, the second snap-fitting cavity, the first snap-fitting portion, the second snap-fitting portion, the first clamping portion and the second clamping portion are gradually designed with a transverse width along the direction perpendicular to the enclosure plate body to form a wedge-shaped structure, so that the support and the positioning protrusion are snap-fitted and positioned twice, making the connection between the support and the positioning protrusion more stable, and the clamp and the positioning protrusion are snap-fitted and positioned twice, making the connection between the clamp and the positioning protrusion more stable, preventing accidental disengagement due to vibration.

[0017] In an optional embodiment, the first positioning portion and the second positioning portion are arranged from inside to outside in a direction perpendicular to the enclosure plate body, and the maximum transverse width of the first positioning portion is greater than the maximum transverse width of the second positioning portion;

[0020] The first clamping portion and the second clamping portion are arranged from inside to outside along a direction perpendicular to the enclosure plate body, and the maximum transverse width of the first clamping portion is greater than the maximum transverse width of the second clamping portion.

[0021] The beneficial effects of the above technical solution are as follows: the positioning portion and engaging cavity of the positioning protrusion, the engaging portion of the support, and the clamping portion of the clamp are all configured as a plum blossom structure. This structural design makes the connection between the components more stable and less likely to loosen. The special shape of the plum blossom structure increases the contact area between the components, improving the stability and load-bearing capacity of the connection.

[0063] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0064] The specific embodiments of the present invention are described in detail below in conjunction with the cooling tower photovoltaic widening platform system of the first aspect of the present invention and the cooling tower photovoltaic widening platform system of the second aspect of the present invention.

[0065] According to an embodiment of the present invention, a first aspect provides a protective plate structure, Figures 1 to 7 As shown, it includes a protective plate 1, a support 3 and a clamp 4.

[0066] The protective plate 1 includes a protective plate body 11 and a positioning protrusion 2. There is at least one positioning protrusion 2. The positioning protrusion 2 is integrated with the protective plate body. The positioning protrusion 2 protrudes outward along the outer wall of the protective plate body 11. The positioning protrusion 2 has a positioning portion 22 and a snap-fit cavity 23. The snap-fit cavity 23 has an opening 233 facing inward.

[0067] At least one support 3 is provided, and the number of supports 3 provided is the same as the number of positioning protrusions 2 provided. Support 3 has a clamping portion 32 and a first mounting portion 33. Clamping portion 32 is clamped and positioned within clamping cavity 23, thereby inserting and positioning support 3 within positioning protrusion 2. The first mounting portion and clamping portion 32 are located on either side of opening 233, so that the first mounting portion can be connected to the first positioning member 7 located on the inner side of the enclosure body.

[0068] The clamp 4 is provided with at least one, and the clamp 4 has a clamping portion 43 and a second mounting portion. The clamping portion 43 is adapted to the positioning portion 22 and is clamped and positioned on the positioning protrusion 2. The second mounting portion is suitable for positioning the second positioning member 5 on the enclosure plate 1.

[0069] The above-mentioned enclosure panel structure achieves a snap-fit connection between the positioning protrusion 2 and the enclosure panel by inserting the snap-fit portion 32 of the support 3 into the snap-fit cavity 23 of the positioning protrusion 2. The snap-fit connection between the positioning protrusion 2 and the enclosure panel 4 is achieved by inserting the positioning portion 22 of the positioning protrusion 2 into the clamping portion 43 of the clamp 4. This completely avoids drilling holes or using screws in the enclosure panel body, enabling nail-free connection between the widened platform roof panels and completely eliminating the stress concentration problem caused by screw installation. Since there is no need to drill holes in the enclosure panel or use screws to connect, deformation or cracking of the enclosure panel due to stress concentration is avoided, thereby improving the reliability of the enclosure panel roof.

[0070] The embedded matching design of the clamping cavity 23 and the clamping portion 32, combined with the clamping and fixing of the positioning portion 22 by the clamp 4, forms multiple anti-displacement constraints, effectively resisting dynamic loads such as wind vibration and cooling tower vibration, and avoiding slippage or loosening.

[0071] By combining finite element analysis with field tests, the stress performance of the enclosure panel structure of this embodiment was analyzed and studied in detail. The stress peak in the key area of the enclosure panel was significantly lower than that of the traditional method, which significantly reduced the risk of deformation or cracking and met the requirements of relevant specifications.

[0072] In some embodiments, the enclosure plate structure is cleverly designed, and the snap-in cavity 23 is arranged along the front-to-back direction, allowing the snap-in portion 32 to slide and insert along this direction. The snap-in portion 32 slides along the front-to-back direction and is snapped into the snap-in cavity 23, where it is locked and fixed, and is limited to the left and right by the snap-in cavity 23, completely eliminating the risk of lateral displacement. The clamping portion 43 is a clamping groove, and the clamping portion 43 is arranged along the front-to-back direction. The clamping portion 43 slides along the front-to-back direction and is snapped into the outer side of the positioning portion 22, where it is locked and fixed, and is limited to the left and right by the positioning portion 22. The above-mentioned enclosure plate structure adopts a sliding snap-in method during assembly, which not only simplifies the construction steps and reduces the construction difficulty, but also eliminates the need to drill holes in the enclosure plate 1.

[0073] In some embodiments, the positioning portion 22 includes a first positioning portion 221 and a second positioning portion 222 . The first positioning portion 221 and the second positioning portion 222 are both arranged in a structure in which the lateral width gradually increases and then gradually decreases along a direction perpendicular to the enclosure plate body 11 .

[0074] The engaging cavity 23 includes a first engaging cavity 231 and a second engaging cavity 232 . The first engaging cavity 231 and the second engaging cavity 232 are both configured to have a structure in which the transverse width gradually increases and then gradually decreases along a direction perpendicular to the enclosure plate body 11 .

[0075] The clamping portion 32 includes a first clamping portion 321 and a second clamping portion 322. The first clamping portion 321 is adapted to the first clamping cavity 231, and the second clamping portion 322 is adapted to the second clamping cavity 232. The first clamping portion 321 and the second clamping portion 322 are both arranged in a structural form in which the lateral width gradually increases and then gradually decreases along a direction perpendicular to the protective plate body 11.

[0076] The clamping portion 43 includes a first clamping portion 431 and a second clamping portion 432. The first clamping portion 431 is adapted to the first positioning portion 221, and the second clamping portion 432 is adapted to the second positioning portion 222. The first clamping portion 431 and the second clamping portion 432 are both arranged in a structural form in which the lateral width gradually increases and then gradually decreases along a direction perpendicular to the protective plate body 11.

[0077] In this embodiment, the first positioning portion 221, the second positioning portion 222, the first snap-fitting cavity 231, the second snap-fitting cavity 232, the first snap-fitting portion 321, the second snap-fitting portion 322, the first clamping portion 431 and the second clamping portion 432 are designed to gradually change in lateral width in the direction perpendicular to the enclosure plate body 11 to form a wedge-shaped structure, so that the support 3 and the positioning protrusion 2 are snap-fitted and positioned twice, making the connection between the support 3 and the positioning protrusion 2 more stable, and the clamp 4 and the positioning protrusion 2 are snap-fitted and positioned twice, making the connection between the clamp 4 and the positioning protrusion 2 more stable, thereby preventing accidental disengagement due to vibration.

[0078] In some embodiments, the first positioning portion 221 and the second positioning portion 222 are arranged from inside to outside along a direction perpendicular to the enclosure body 11, and the maximum lateral width of the first positioning portion 221 is greater than the maximum lateral width of the second positioning portion 222. The first snap-fitting cavity 231 and the second snap-fitting cavity 232 are arranged from inside to outside along a direction perpendicular to the enclosure body 11, and the maximum lateral width of the first snap-fitting cavity 231 is greater than the maximum lateral width of the second snap-fitting cavity 232. The first snap-fitting portion 321 and the second snap-fitting portion 322 are arranged from inside to outside along a direction perpendicular to the enclosure body 11, and the maximum lateral width of the first snap-fitting portion 321 is greater than the maximum lateral width of the second snap-fitting portion 322. The first clamping portion 431 and the second clamping portion 432 are arranged from inside to outside along a direction perpendicular to the enclosure body 11, and the maximum lateral width of the first clamping portion 431 is greater than the maximum lateral width of the second clamping portion 432.

[0079] In this embodiment, the positioning portion 22 and engaging cavity 23 of the positioning protrusion 2, the engaging portion 32 of the support 3, and the clamping portion 43 of the clamp 4 are all configured as a plum blossom structure. This structural design makes the connection between the components more stable and less likely to loosen. The special shape of the plum blossom structure increases the contact area between the components, improving the stability and load-bearing capacity of the connection.

[0080] In some embodiments, the support 3 is formed by bending a plate-like structure in one piece. The support 3 includes a support body 31, a clamping portion 32 and a first mounting portion 33, and the clamping portion 32 and the first mounting portion 33 are located on both sides of the support body 31. The clamping portion 32 is used to cooperate with the clamping cavity 23 of the enclosure body 11 to achieve a stable connection between the support 3 and the enclosure body 11. The first mounting portion 33 is used to connect with other structural members or components so that the entire enclosure structure can be installed in a predetermined position. This design of the support 3 formed by bending in one piece not only simplifies the manufacturing process and reduces production costs, but also improves the overall strength and stability of the structure. At the same time, this design of the support 3 also makes the installation process simpler and faster, thereby improving construction efficiency.

[0081] The first mounting portion 33 includes a first mounting plate. The first mounting plate is provided with at least one first connecting hole 331 . The first mounting portion 33 is connected to the first positioning member 7 via a first connecting bolt 332 . The first connecting bolt 332 passes through the first connecting hole 331 .

[0082] In some embodiments, the clamp 4 includes a first clamping plate 41 and a second clamping plate 42, the first clamping plate 41 includes a first L-shaped plate 411 and a first bent plate 412 connected as one piece, and the second clamping plate 42 includes a second L-shaped plate 421 and a second bent plate 422 connected as one piece. The first bent plate 412 and the second bent plate 422 are arranged opposite to each other and the two constitute a clamping portion 43. The transverse plate of the second L-shaped plate 421 is staggeredly connected to the transverse plate of the first L-shaped plate 411 and is located on the outside of the transverse plate of the first L-shaped plate 411. A second connecting hole 424 is provided on the transverse plate of the second L-shaped plate 421 to constitute a second mounting portion for connecting with other structural members or components to achieve fixation and positioning of the clamp 4 in the entire enclosure structure. The second mounting portion is connected to the second positioning member 5 by a second connecting bolt 45, and the second connecting bolt 45 passes through the second connecting hole 424.

[0083] In this embodiment, the clamping portions 43 of the first and second clamping plates 41, 42 securely hold the support 3 on the enclosure body 11, ensuring structural stability and reliability. The staggered connection of the crossbars of the second L-shaped plate 421 and the first L-shaped plate 411 not only increases the flexibility of the clamp 4 but also allows it to better accommodate components of varying shapes and sizes, enhancing its versatility and practicality.

[0084] More specifically, at least one first positioning hole 413 is defined on the vertical plate of the first L-shaped plate 411, and at least one second positioning hole 423 is defined on the vertical plate of the second L-shaped plate 421. The second positioning hole 423 corresponds to the position of the first positioning hole 413. The first clamping plate 41 and the second clamping plate 42 are connected by a positioning bolt 44. The positioning bolt 44 passes through the second positioning hole 423 and the first positioning hole 413 and is tightened by a nut. When positioning the clamp 4 on the positioning protrusion 2, the first clamping plate 41 and the second clamping plate 42 can be placed in sequence on the positioning protrusion 2, and then the first clamping plate 41 and the second clamping plate 42 can be connected by the positioning bolt 44, thereby making the connection and positioning of the clamp 4 to the positioning protrusion 2 very convenient.

[0085] According to an embodiment of the present invention, a second aspect provides a cooling tower photovoltaic widening platform system, combined with Figures 1 to 12 As shown, the system includes a widening platform main structure member 8, a protective panel structure, and a photovoltaic module. The widening platform main structure member 8 is arranged on the periphery of the cooling tower. The protective panel structure is positioned on the widening platform main structure member 8 via a first positioning member 7. The photovoltaic module is positioned on the protective panel structure via a second positioning member 5.

[0086] In some embodiments, the second positioning member 5 is a photovoltaic rail, the photovoltaic assembly includes a plurality of photovoltaic panels 6 , and two adjacent photovoltaic panels 6 are positioned on the photovoltaic rail via a photovoltaic panel pressing block 61 .

[0087] In some embodiments, the U-shaped photovoltaic rail is connected to the top of the fixture via bolts. Since the photovoltaic rail can be flexibly adjusted at an angle based on the shape of the widening platform, various arrangements of photovoltaic panels, such as arc shapes, can be achieved. Because the fixture is positioned on the outwardly protruding positioning protrusions 2, sufficient space is provided between the enclosure and the photovoltaic panel, facilitating the connection of wires between the panels while ensuring sufficient heat dissipation space for the panels, thereby achieving efficient power generation.

[0088] Traditional roofing panels typically have a service life of 10-20 years, while photovoltaic projects are typically designed for a 25-year service life. To address this, the panel structure in this embodiment utilizes an aluminum alloy substrate with a longer corrosion resistance. Furthermore, the profiled aluminum panels are topcoated with a double-sided fluorocarbon coating, which offers enhanced corrosion resistance. This ensures that the metal roofing of the cooling tower expansion platform has a service life that matches the 25-year service life of the photovoltaic modules, ensuring that the photovoltaic project does not require panel replacement within its normal design lifespan.

[0089] Furthermore, the aluminum alloy baseplate's lightweight construction facilitates installation and maintenance. Its excellent corrosion resistance effectively withstands adverse factors such as humidity and salt spray in the cooling tower environment, ensuring the stability and durability of the enclosure structure. A double-sided fluorocarbon coating not only enhances corrosion resistance but also provides excellent weather and UV resistance, further extending the enclosure's service life, making it adaptable to a variety of harsh climates and maintaining the overall efficiency and safety of the photovoltaic widening platform system.

[0090] In some embodiments, the first positioning member 7 is a support purlin. A roof base plate and insulation layer are provided between the support purlin and the main structural members 8 of the widening platform to accommodate various roof construction requirements. In this embodiment, the photovoltaic modules and the photovoltaic rails are connected using bolts, simplifying the construction and installation of the widening platform photovoltaic platform.

[0091] In some embodiments, a widened platform walkway 9 is further provided on the side of the photovoltaic module.

[0092] Currently, domestic cooling towers, whether steel or concrete, all feature steel structures, with 3-4mm flat steel roofing. The platform in this embodiment utilizes a 1.2mm thick extruded aluminum alloy roof, replacing the traditional, bulky 3-4mm flat steel roofing. This ensures that the platform's roofing meets the required process requirements while also providing a superior platform for subsequent photovoltaic panel installation.

[0093] Furthermore, the 1.2mm-thick extruded aluminum alloy roof significantly reduces overall weight compared to traditional 3-4mm flat steel roofs. This not only reduces material transportation and installation costs, but also improves construction efficiency and reduces energy consumption. The excellent plasticity of the aluminum alloy sheet allows for easy processing into various shapes and sizes to accommodate the complex and diverse structural requirements of the cooling tower's widening platform.

[0094] The specific installation process of the above cooling tower photovoltaic widening platform system is as follows:

[0095] The corrugated aluminum alloy plate is connected to the widening platform support purlin through the matching support 3, and the enclosure plate is connected to the 2mm thick galvanized steel plate support through a special locking machine. While ensuring that the widening platform enclosure plate has sufficient bearing capacity, it also realizes nail-free connection between adjacent roof panels.

[0096] After the widening platform roof panels are installed, a clamp (plum blossom head panel clamp) that matches the aluminum alloy corrugated steel sheet is set in the corresponding area where the photovoltaic panels are to be installed. The specially designed clamp in this invention not only provides a connection support for the photovoltaic rails, but also strengthens the wind resistance of the enclosure panels.

[0097] Install the photovoltaic rail on the fixture, and ensure a certain distance between the photovoltaic rail and the enclosure. Install the photovoltaic panel 6 on the photovoltaic rail.

[0098] The cooling tower photovoltaic platform system features corrosion-resistant corrugated aluminum sheets fixed to the supporting purlins. PV rails are mounted on the sheets using retaining clips, and the appropriate photovoltaic panels are then installed according to project requirements to complete the assembly. While ensuring secure connections to the steel structure's roof sheathing, this system also fully utilizes unused rooftop space for photovoltaic power generation, saving land and reducing project costs.

[0099] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
