Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel installation, specifically to a rooftop photovoltaic panel bracket and rooftop installation method that facilitates installation. Background Technology

[0002] In the construction of new energy photovoltaic panel installation projects, roof photovoltaic panel support systems are mostly fixed by pre-embedded steel plate welding or rigid connection with expansion bolts. Traditional welding processes have the following defects: 1. Welding speed is slow and requires professional welders. The large amount of open flame generated on site can easily ignite roof waterproofing materials (especially asphalt-based membranes), posing a serious fire hazard; 2. The quality of the weld is significantly affected by the operator's skill level. After the weld rusts and cracks, it can easily lead to the overall instability of the support system; a more prominent problem is that traditional support systems lack secondary waterproof protection measures. The drilled holes are only filled with ordinary sealant, which is prone to aging and cracking under long-term ultraviolet radiation, causing rainwater leakage.

[0003] In addition, roofs are divided into flat roofs and pitched roofs, and there are significant differences in their installation. Firstly, when installing photovoltaic panels on a pitched roof, it is not necessary to set a sun-facing angle, and the wind resistance is better after installation. However, pitched roofs are mostly tiled, making it difficult to install large keel supports embedded in the tile surface. Currently, most are assembled and welded, with bolts only set on the tile surface, resulting in low structural strength and difficulty in withstanding long-term wind and sun exposure. While it is convenient to pre-embed bolts when installing on a flat roof, the photovoltaic panels need to be set to a sun-facing angle. The sun-facing side has better wind resistance, but when the back side is hit by strong winds, the photovoltaic panels are easily blown away, and the keel and bolts are broken. In severe cases, they may be scattered and fall to the ground, posing a safety hazard to people. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an easy-to-install roof photovoltaic panel bracket and roof installation method, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a roof photovoltaic panel support that is easy to install, comprising warp and weft steel strands, wherein the warp and weft steel strands are provided in multiple sets and arranged in a grid pattern, any two warp and weft steel strands are perpendicular to each other, and the ends of the warp and weft steel strands can be used to fix the warp and weft steel strands on the lateral facade.

[0006] It also includes fixed-point fixing bolts, which are installed at the intersection of any two warp and weft steel strands to connect the intersection of the warp and weft steel strands to the roof surface, and photovoltaic panel mounting brackets, which are installed on the fixed-point fixing bolts.

[0007] Preferably, the photovoltaic panel mounting frame includes a square steel frame and columns. The middle position of the square steel frame is fixed with cross steel, and the columns are fixedly installed at the four corners of the bottom of the square steel frame. The columns are fixedly connected with fixed bolts.

[0008] Preferably, the photovoltaic panel mounting frame further includes a tripod, the bottom of which is fixed to a square steel frame, and the top of which is equipped with two diagonal anchors. The end of the diagonal anchor away from the tripod is fixedly installed on the corresponding fixed bolt by a column.

[0009] Preferably, the fixed-point fixing bolt includes four sets of clamping pipes, each of which has a half hole corresponding to the warp and weft steel strands. When the four sets of clamping pipes are closed, they form a round tube and lock the intersection of the two warp and weft steel strands. There are gaps in the clamping pipes when they are initially closed.

[0010] It also includes a ground jack, a mover, and a damper. The damper has a two-part structure. When they are closed, the upper end forms a T-shaped platform and the lower end forms a T-shaped groove. The damper is used to install in the bottom of the four sets of clamping pipes. When the four sets of clamping pipes are tightened and closed, the damper can be fixed in place by the T-shaped platform. The mover has a T-shaped structure. Its upper end can be inserted into the T-shaped groove. There is a slight movement gap between the two. The bottom end of the mover is fixed to the ground jack.

[0011] The fixed anchor also includes a protective cover, which is a conical structure with the opening facing downwards. The pointed structure at the upper end of the protective cover is fitted onto the anchor and fixed to it.

[0012] Preferably, the fixed-point fixing bolt further includes a stabilizing platform. The bottom end of the stabilizing platform is a boss structure. The bottom end of the stabilizing platform is used to install in the upper end of the four sets of clamping pipes. After the four sets of clamping pipes are tightened and closed, the stabilizing platform can be fixed according to the boss. The upper end of the stabilizing platform is a flange-shaped platform, and the column is installed on the flange-shaped platform with bolts.

[0013] Preferably, the fixed-point fixing bolt further includes hollow studs and nuts. There are two sets of hollow studs, which are fixed at the upper and lower ends of the clamping tube respectively. The expansion angle of the hollow studs is 90 degrees. When the four clamping tubes are closed, the hollow studs form a spiral tube. The inner diameter of the spiral tube is smaller than the inner diameter of the round tube. The boss and T-shaped platform match the diameter difference between the spiral tube and the round tube.

[0014] The hollow studs are all designed with a sloping structure at the end facing the clamping tube. One side of the nut is a conical cover. The nut is used to screw onto the screw tube. When it is screwed and approaches the clamping tube, the conical cover gradually squeezes the sloping structure of the hollow stud, thereby squeezing and closing the four clamping tubes.

[0015] Preferably, the fixed bolt further includes a clamp, and the outer ring of the retaining tube is provided with grooves. After the retaining tube is closed, the clamp is engaged in the groove for secondary fixation of the retaining tube.

[0016] Preferably, the warp and weft steel strands include steel wires, tensioners, and wall bolts, with the wall bolts connected to the steel wires via the tensioners.

[0017] Preferably, it also includes a side beam, the bottom end of which is used to fix to the edge of the sloping roof, and wall bolts can be fixedly installed on the side beam.

[0018] A method for installing a rooftop photovoltaic panel bracket includes the following steps:

[0019] S1: When installing on a flat roof, fix the steel wire to the side wall of the roof with wall bolts, and use the four walls and tensioners to tighten the steel wire. Arrange the wires in a grid structure with equal intervals. When installing on a sloping roof, connect the side beam to the wall embedded parts and fix it to the side of the sloping roof. Similarly, fix the steel wire with wall bolts.

[0020] S2: Install the clamp pipe according to the steel wire intersection point, and pre-embed the ground bolt according to the hole drilled at the intersection point. After the ground bolt is connected to the roof, use the damper to connect the actuator, so as to realize the soft connection between the intersection point and the roof. When installing the ground bolt, ensure that the protective cover is tightly attached to the roof.

[0021] S3: Next, install the stabilizing platform and tighten the nuts to keep the stabilizing platform parallel to the roof;

[0022] S4: Use columns to install a square steel frame. When installing on a sloping roof, install the photovoltaic panels directly on the square steel frame. When installing on a flat roof, install a tripod on the square steel frame again, and then install the photovoltaic panels on the tripod. Finally, use a diagonal anchor to fix it at another intersection.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This easy-to-install roof photovoltaic panel bracket and roof installation method uses steel strands and fixed bolts to connect the mesh-like steel strands together, forming a large mesh. The edges of the mesh play a major role in connecting and tightening, while the intersections play an auxiliary stabilizing role. When installing a large number of photovoltaic panels, the number of holes drilled in the ground is reduced, and the possibility of roof leakage is greatly reduced. When exposed to strong winds, the steel wire mesh is woven into a whole and is not easily blown away. The mesh-like steel wire structure has a certain energy absorption effect, so the installed photovoltaic panels have good stability and strong load-bearing capacity.

[0025] 2. This easy-to-install rooftop photovoltaic panel bracket and installation method, due to the inclusion of a mover and a damper, allows for a certain range of motion after connection. The weight of the installed photovoltaic panel, along with the tripod and square steel frame, ensures that the damper and mover remain completely stationary. When subjected to crosswinds, the slight movement can cause the linearly or matrix-distributed photovoltaic panels to undergo a certain amount of wind-induced slight movement. This slight movement can significantly reduce the load on the photovoltaic panels against the crosswinds. The woven steel wire mesh also has this buffering effect. Therefore, even tilted photovoltaic panels are not afraid of strong winds, greatly reducing the problem of photovoltaic panels falling from the roof.

[0026] 3. The easy-to-install roof photovoltaic panel bracket and roof installation method include the installation of a protective cover. After the ground bolts are pre-buried, the protective cover is used to block the drilling location from the external environment. Later, waterproof membrane can be covered on the edge of the protective cover, which improves the rust prevention and rain leakage prevention capabilities.

[0027] 4. The easy-to-install roof photovoltaic panel bracket and roof installation method, by setting up inclined anchors, further enhances the wind resistance of the inclined back of the photovoltaic panel. Compared with the existing technology, the design of the inclined anchors greatly improves the structural strength of the photovoltaic panel installation.

[0028] 5. This easy-to-install roof photovoltaic panel bracket and roof installation method, by setting side beams, can be connected to the edge wall of the sloping roof. Generally speaking, the load-bearing capacity of the embedded parts of the sloping roof is relatively weak. Therefore, placing the stress point on the edge wall or the cast beam can effectively improve the structural strength of the photovoltaic panel installation. Attached Figure Description

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0041] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0043] like Figure 1-9 As shown, a roof photovoltaic panel support that is easy to install includes warp and weft steel strands 1. The warp and weft steel strands 1 are provided in multiple sets and arranged in a grid pattern. Any two warp and weft steel strands 1 are perpendicular to each other. The ends of the warp and weft steel strands 1 can be used to fix the warp and weft steel strands 1 on the side facade.

[0044] It also includes a fixed fixing bolt 2, which is installed at the intersection of any two warp and weft steel strands 1 to connect the intersection of the warp and weft steel strands 1 to the roof surface, and a photovoltaic panel mounting frame 3, which is installed on the fixed fixing bolt 2.

[0045] The warp and weft steel strand 1 is made of standard 19 strands of steel wire twisted together, and the material is 304 stainless steel. When building the warp and weft grid, the warp and weft steel strand 1 in the two directions are staggered vertically, and the two should be in contact or the distance between them should not be greater than 5mm. After the warp and weft steel strand 1 is installed on the side vertical surface, it should be in a taut state, and the sag should not be greater than 1 / 50 of the rope length, and the absolute value should not exceed 50mm. The actual situation needs to be determined by the steel wire diameter, length, tension force, unit length mass and load distribution. The sag should not be easily noticeable when viewed with the naked eye.

[0046] When the fixed-point fixing bolt 2 is installed at the intersection of the steel wires, it is in a matrix distribution state. When the fixed-point fixing bolt 2 is installed, its height should be consistent with the height of the original steel wire to avoid pulling down the overall height of the steel wire after the fixed-point fixing bolt 2 is installed, resulting in downward tension.

[0047] The photovoltaic panel mounting frame 3 is set as a non-standard structure, which can be customized according to the actual size of the photovoltaic panel. When changing its size, the distance between the steel wires can also be changed according to the size of the photovoltaic panel mounting frame 3, and the intersecting rectangle can be switched between a square or a rectangle.

[0048] In an optional embodiment, the photovoltaic panel mounting frame 3 includes a square steel frame 301 and columns 302. The middle position of the square steel frame 301 is fixed with cross steel, and the columns 302 are fixedly installed at the four corners of the bottom end of the square steel frame 301. The columns 302 are fixedly connected to the fixed bolts 2.

[0049] In this embodiment, the square steel frame 301 is manufactured by welding and is in a prepared state before the photovoltaic panels are installed. It is directly assembled during installation. After the square steel frame 301 is manufactured by welding, the surface is galvanized to extend its service life. The column 302 is in a separate state from the square steel frame 301. The two are installed using bolts. The column 302 is also connected to the fixed bolt 2 using bolts.

[0050] In another embodiment, the photovoltaic panel mounting frame 3 also includes a tripod 303. The bottom end of the tripod 303 is fixed to the square steel frame 301, and the top end of the tripod 303 is equipped with two inclined anchors 304. The end of the inclined anchor 304 away from the tripod 303 is fixedly installed on the corresponding fixed bolt 2 through the column 302.

[0051] In this embodiment, the tilt angle of the tripod 303 is the final angle of sunlight exposure for the photovoltaic panel. The optimal installation angle (tilt angle) of the photovoltaic panel mainly depends on the latitude of the installation site, and is generally equal to the local latitude or slightly adjusted (such as latitude +5° to 15°). Specific optimization needs to be combined with factors such as season and terrain. The tripod 303, like the square steel frame 301, is in a pre-fabricated state before the photovoltaic panel is installed. It is constructed by welding a steel frame, and after welding, the surface is galvanized for rust prevention. The connection between the inclined anchor 304 and the tripod 303 is also achieved using a column 302, which is fixed to the side of the tripod 303 with bolts.

[0052] In an optional embodiment, the fixed bolt 2 includes four sets of clamping tubes 201, each of which is provided with a half hole 202 corresponding to the warp and weft steel strands 1. When the four sets of clamping tubes 201 are closed, they form a round tube 203 and lock the intersection of the two warp and weft steel strands 1. There are gaps in the clamping tubes 201 when they are initially closed.

[0053] It also includes a ground bolt 204, a mover 205, and a damper 206. The damper 206 has a two-part structure. When closed, the upper end forms a T-shaped platform 207, and the lower end forms a T-shaped groove 208. The damper 206 is used to install in the bottom of the four sets of clamping pipes 201. When the four sets of clamping pipes 201 are tightened and closed, the damper 206 can be fixed according to the T-shaped platform 207. The mover 205 has a T-shaped structure. Its upper end can be inserted into the T-shaped groove 208. There is a slight movement gap between the two. The bottom end of the mover 205 is fixed to the ground bolt 204.

[0054] The fixed bolt 2 also includes a protective cover 209, which is a conical structure with the opening facing downwards. The pointed structure at the upper end of the protective cover 209 is fitted onto the ground bolt 204 and fixed to the ground bolt 204.

[0055] In this embodiment, the clamping tube 201 is a 1 / 4 tubular structure, the diameter of the half hole 202 is set to match the diameter of the warp and weft steel strands 1, and there is a height difference between the half holes 202 on the clamping tube 201, which matches the longitudinal and transverse height difference of the warp and weft steel strands 1.

[0056] The ground bolt 204 is an expansion bolt with an M16-M20 specification. The actuator 205 is connected to the ground bolt 204 by welding. After welding, the two are treated with anti-rust treatment. The damper 206 is a semi-circular tubular structure. Its bottom end can wrap around the actuator 205. After being wrapped, the actuator 205 has a movement space in the damper 206. This movement space is coordinated with the elastic deformation of the warp and weft steel strands 1.

[0057] The protective cover 209 is made of aluminum alloy. When installing the ground bolt 204, after tightening the ground bolt 204, the lower end of the protective cover 209 should be tightly against the bottom surface. Once a slight deformation occurs at the upper end, stop tightening the ground bolt 204. At this point, ensure that the expansion joint inside the ground bolt 204 is under stress. The tensile strength of the ground bolt 204 should be greater than 50,000 N. The ground should be cleaned before installing the protective cover 209. After it is tightly against the bottom surface, it needs to have a certain degree of sealing. Later, use a sealant or waterproof membrane to seal its sides. This method is easier to ensure a seal than treating the bolt holes.

[0058] In an optional embodiment, the fixed bolt 2 further includes a stabilizing platform 210. The bottom end of the stabilizing platform 210 is configured as a boss 211 structure. The bottom end of the stabilizing platform 210 is used to install in the upper end of the four sets of clamping pipes 201. After the four sets of clamping pipes 201 are tightened and closed, the stabilizing platform 210 can be fixed according to the boss 211. The upper end of the stabilizing platform 210 is a flange-shaped platform, and the column 302 is installed on the flange-shaped platform with bolts.

[0059] In this embodiment, the stabilizing platform 210 is provided with multiple positioning holes for installing bolts. When the column 302 is installed on the stabilizing platform 210, the bolts are installed in the positioning holes. The stabilizing platform 210 is used to install the square steel frame 301.

[0060] In an optional embodiment, the fixing bolt 2 further includes a hollow stud 212 and a nut 213. There are two sets of hollow studs 212, which are respectively fixed at the upper and lower ends of the clamping tube 201. The expansion angle of the hollow studs 212 is 90 degrees. When the four clamping tubes 201 are closed, the hollow studs 212 form a spiral tube 214. The inner diameter of the spiral tube 214 is smaller than the inner diameter of the round tube 203. The boss 211 and the T-shaped platform 207 are matched with the diameter difference between the spiral tube 214 and the round tube 203.

[0061] The hollow studs 212 are all designed with a sloping structure at the end facing the retaining tubes 201. One side of the nut 213 is a conical cover 215. The nut 213 is used to screw onto the screw tube 214. When it is screwed and approaches the retaining tubes 201, the conical cover 215 gradually squeezes the sloping structure of the hollow studs 212, thereby squeezing and closing the four retaining tubes 201.

[0062] In this embodiment, the boss 211 and the T-shaped platform 207 are installed inside the four sets of retaining tubes 201. When they are in full contact, there is a certain gap between the four sets of retaining tubes 201. When the nut 213 is tightened, the gap between the retaining tubes 201 gradually narrows. The tightly fitted retaining tubes 201 can stably fix the boss 211 or the T-shaped platform 207. The boss 211 and the T-shaped platform 207 have a certain length in the retaining tubes 201, so the installation is firm and the amount of bolts used is reduced. Installation and disassembly are also convenient.

[0063] In an optional embodiment, the fixing bolt 2 further includes a clamp 216, and the outer ring of the retaining tube 201 is provided with a groove 217. After the retaining tube 201 is closed, the clamp 216 is engaged in the groove 217 for secondary fixation of the retaining tube 201.

[0064] In this embodiment, the clamp 216 is used for final fixation, and its end is fastened with two sets of bolts. Whether to use it during actual installation depends on the requirements.

[0065] In an optional embodiment, the warp and weft steel strand 1 includes a steel wire 101, a tensioner 102, and a wall bolt 103, with the wall bolt 103 connected to the steel wire 101 via the tensioner 102.

[0066] In this embodiment, the tensioner 102 is used to tighten the steel wire 101 when it is installed, or to adjust it again if the steel wire 101 sags after a period of installation. The wall bolt 103 is the same as the ground bolt 204, both being expansion bolts with M16-M20 specifications. The wall bolt 103 is connected to the side wall of the roof, placing the main stress point of the steel wire 101 on the wall. Generally, the bottom of the roof wall is a concrete structure, and the top is made of hollow bricks. In actual installation, the wall bolt 103 should be installed at the concrete pouring position.

[0067] In another embodiment, a side beam 104 is also included, the bottom end of which is used to fix to the edge of the sloping roof, and a wall bolt 103 can be fixedly installed on the side beam 104.

[0068] In this embodiment, the side beam 104 is used to serve the function of the flat-roofed wall mentioned above. Since the sloping roof does not have a cast-in-place wall beam, but the end of the sloping roof has a wall, the side beam 104 can be installed on the wall using embedded parts, and then the wall bolt 103 can be installed on the side beam 104.

[0069] A method for installing a rooftop photovoltaic panel bracket includes the following steps:

[0070] S1: When installing on a flat roof, fix the wall bolts 103 of the steel wire 101 to the side wall of the roof. Use the four walls and tensioner 102 to tighten the steel wire 101 and arrange it in a grid structure at equal intervals. When installing on a sloping roof, the side beam 104 needs to be connected to the wall embedded parts and fixed on the side of the sloping roof. Similarly, use the wall bolts 103 to fix the steel wire 101.

[0071] S2: Install the clamp pipe 201 at the intersection of steel wire 101, and pre-embed the ground bolt 204 by drilling holes at the intersection. After the ground bolt 204 is connected to the roof, use the damper 206 to connect the actuator 205, so as to achieve a soft connection between the intersection and the roof. When installing the ground bolt 204, ensure that the protective cover 209 is close to the roof.

[0072] S3: Next, install the stabilizing platform 210 and tighten the nut 213 to keep the stabilizing platform 210 parallel to the roof;

[0073] S4: Install the square steel frame 301 using the column 302. When installing on a sloping roof, install the photovoltaic panel directly on the square steel frame 301. When installing on a flat roof, install the tripod 303 on the square steel frame 301 again, and install the photovoltaic panel on the tripod 303. Finally, use the inclined anchor 304 to fix it on another intersection point.

The bottom end of the stabilizing platform (210) is used to install in the upper end of the four sets of clamping pipes (201). After the four sets of clamping pipes (201) are tightened and closed, the stabilizing platform (210) can be fixed according to the boss (211). The upper end of the stabilizing platform (210) is a flange-shaped platform. The column (302) is bolted to the flange-shaped platform. The fixed bolt (2) also includes a hollow stud (212) and a nut (213). There are two sets of hollow studs (212), which are fixed at the upper and lower ends of the clamping tube (201) respectively. The expansion angle of the hollow stud (212) is 90 degrees. When the four clamping tubes (201) are closed, the hollow studs (212) form a spiral tube (214). The inner diameter of the spiral tube (214) is smaller than the inner diameter of the round tube (203). The boss (211) and the T-shaped platform (207) match the diameter difference between the spiral tube (214) and the round tube (203). The hollow stud (212) is designed with a sloping structure at the end facing the retaining tube (201). One side of the nut (213) is a conical cover (215). The nut (213) is used to screw onto the screw tube (214). When it is screwed and approaches the retaining tube (201), the conical cover (215) gradually squeezes the sloping structure of the hollow stud (212), thereby squeezing and closing the four retaining tubes (201).
