Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of electric power engineering, and in particular to a photovoltaic bracket for a concrete gas tower. Background Art

[0002] With the development of new energy technologies, integrating photovoltaic modules into buildings and utilizing the roof area of ​​buildings to install photovoltaic modules for photovoltaic power generation has become an important power generation method. However, the roofs of existing buildings, especially residential buildings, are generally flat concrete roofs. For this type of roof, the existing technology generally uses a method of installing photovoltaic modules on the roof of the building using concrete piers and counterweights. That is, multiple concrete piers are pre-cast, and then the bottom of the photovoltaic bracket is fixed to the concrete piers. The entire photovoltaic bracket, together with the concrete piers cast at the bottom, is then placed on the building roof. The photovoltaic bracket is fixed by the gravity of the concrete piers themselves, thereby placing the photovoltaic bracket on the building roof and installing the photovoltaic modules. However, the photovoltaic bracket needs to rely on the gravity of the concrete piers to be fixed, which requires that the weight of the concrete piers must be greater than a certain threshold. When a concrete air tower is installed on the roof for ventilation, the bearing capacity of the air tower structure is generally low and cannot support the weight of the concrete piers. If the concrete pier counterweight method is used to install photovoltaic modules on a roof with an air tower structure, it is easy to cause the air tower to collapse, posing certain safety hazards. As a result, existing photovoltaic module installation structures cannot be well applied to roofs with air tower structures. Utility Model Content

[0026] Reference Figure 1A and Figure 1B The first embodiment of the present invention provides a photovoltaic support for a concrete air building 102, comprising:

[0027] A plurality of implant structures 101, each of which includes a fixing plate 1011, a support plate 1012, and a first connecting structure connecting the fixing plate 1011 and the support plate 1012, the fixing plate 1011 abuts against the upper surface of the gas tower 102, a plurality of bolts are provided on the side of the fixing plate 1011 facing the gas tower 102, a plurality of bolt mounting holes are provided on the upper surface of the gas tower 102, a chemical hose is installed inside the bolt mounting holes, the bolts of the fixing plate 1011 are implanted in the bolt mounting holes and fixed to the bolt mounting holes by the sol in the chemical hose, the upper surface of the support plate 1012 is parallel to the lower surface of the fixing plate 1011, and the support plate 1012 is provided with a first strip-shaped hollow portion, wherein the plurality of implant structures 101 are arranged side by side above the gas tower 102 to form at least two mutually parallel mounting rails;

[0028] The keel 103 has a one-to-one correspondence with the mounting rails. The keel 103 abuts against the support plates 1012 of the multiple implant structures 101 that constitute the corresponding mounting rails. Bolt slots 1031 are provided at the bottom and top of the keel 103. The keel 103 and the multiple support plates 1012 abutting against the keel 103 are fixed by bolts passing through the bottom of the keel 103 and the first strip-shaped hollow portion. The opening width of the bolt slot 1031 is greater than the diameter of the bolt screw and less than the width of the bolt head. The width of the bolt slot 1031 is greater than the width of the head.

[0029] The pressing block 104 is fixed above the keel 103. The bottom width of the pressing block 104 in the horizontal direction is smaller than the width of the keel 103. A horizontal protrusion 1041 is provided on the top of the pressing block 104. The lower surface of the horizontal protrusion 1041 is parallel to the upper surface of the keel 103. The pressing block 104 and the keel 103 are fixed by bolts passing through the bolt groove 1031 on the top of the pressing block 104 and the keel 103. After the pressing block 104 is fixed above the keel 103, the protrusion and the upper surface of the keel 103 form a clamping track, and the photovoltaic module 105 is installed on the clamping track.

[0030] In this embodiment, the implantation structure 101 is used to enable the photovoltaic mounting bracket to be firmly fixed above the air tower 102. The implantation structure 101 includes a fixing plate 1011 and a support plate 1012. The fixing plate 1011 is in contact with the upper surface of the air tower 102, and a plurality of bolts are provided on the side of the fixing plate 1011 facing the air tower 102. At the same time, a plurality of bolt mounting holes are opened downward on the upper surface of the air tower 102, and the bolts of the fixing plate 1011 are implanted into the bolt mounting holes, so that the implantation structure 101 is partially implanted into the air tower 102 to install the photovoltaic mounting bracket above the air tower 102. Specifically, the bolt mounting holes can be opened by drilling holes on the upper surface of the air tower 102. It is understandable that since the air tower 102 is made of concrete, the bolt mounting holes opened by drilling cannot fit tightly with the bolts. Based on this, in this embodiment, a chemical hose is placed in the bolt mounting hole. The chemical hose contains a sol composed of an adhesive and a curing agent. Before the chemical hose ruptures, the adhesive and the curing agent are isolated, so that the sol remains in a colloidal and flowable state. When the bolt is screwed into the bolt mounting hole, the chemical hose ruptures under the pressure of the bolt, and the sol inside the chemical hose flows out, filling the gap between the bolt and the side wall of the bolt mounting hole. Afterwards, the adhesive undergoes a polymerization reaction under the action of the curing agent and gradually solidifies. Under the action of the solidified sol, the bolt can be firmly fixed inside the bolt mounting hole, thereby allowing the entire implant structure 101 to be firmly installed above the air tower 102. The photovoltaic mounting bracket is fixed by a relatively firm fixing method between the implant structure 101 and the air tower 102, without the need to fix the photovoltaic mounting bracket by a concrete pier counterweight method. This greatly reduces the weight of the photovoltaic mounting bracket so that it does not exceed the bearing capacity of the air tower 102 and cause the air tower 102 to collapse. Afterwards, multiple implant structures 101 are arranged side by side to form at least two parallel installation tracks, and keels 103 and pressing blocks 104 are sequentially installed above the implant structures 101 to form a clamping track for installing photovoltaic components 105.

[0031] It is understood that by keeping the inclination of the photovoltaic module 105 consistent with the inclination of the upper surface of the air tower 102, that is, making the upper surface of the photovoltaic module 105 and the upper surface of the air tower 102 parallel, each position on the upper surface of the air tower 102 can relatively evenly bear the pressure caused by the weight of the photovoltaic module 105, thereby preventing the air tower 102 from being subjected to excessive gravity of the photovoltaic module 105 in a local area and causing the air tower 102 to collapse. In addition, the areas of the photovoltaic module 105 and the air tower 102 subjected to external pressures such as wind or rain weight can be made to overlap to the greatest extent. In this way, compared with the force-bearing area of ​​the air tower 102 itself subjected to external forces such as wind, the total force-bearing area of ​​the air tower 102 and the photovoltaic module 105 subjected to external forces such as wind will not increase too much. In this way, before and after the installation of the photovoltaic modules 105, the pressure caused by external forces such as wind that the air tower 102 needs to withstand will not increase significantly, which can effectively avoid the collapse of the air tower 102 caused by the increase in external pressure that the air tower 102 needs to withstand due to the installation of the photovoltaic modules 105. Based on this, in this embodiment, the upper surface of the support plate 1012 of each implant structure 101 and the lower surface of the fixing plate 1011 remain parallel, so that the clamping plane of the clamping track formed by subsequently installing the keel 103 and the pressure block 104 above the implant structure 101 can remain parallel to the roof. After the two ends of the photovoltaic module 105 are clamped on the clamping track, the plane where the photovoltaic module 105 is located can remain parallel to the roof.

[0032] In one embodiment, the support plate 1012 is provided with a first strip-shaped hollow portion, and a bolt slot 1031 is opened at the bottom of the keel 103. The opening width of the bolt slot 1031 is greater than the diameter of the screw and smaller than the width of the bolt head. The slot width of the bolt slot 1031 is greater than the width of the bolt head. In this way, the bolt head is placed in the bolt slot 1031, and the screw protrudes from the keel 103 through the opening of the bolt slot 1031 and is passed through the first strip-shaped hollow portion. The bolt is then tightened with a nut to install the keel 103 above the implant structure 101. It can be understood that the length direction of the bolt groove 1031 at the bottom of the keel 103 and the length direction of the first strip-shaped hollow portion are perpendicular to each other, and the length of the first strip-shaped hollow portion is greater than the diameter of the screw. In this way, the position of the keel 103 on the support plate 1012 has a certain adjustable range. Before tightening the bolts to fix the keel 103, the distance between the keels 103 installed on different mounting rails can be adjusted according to the width of the photovoltaic component 105, so that the two adjacent keels 103 can tightly clamp the photovoltaic component 105.

[0033] A plurality of pressing blocks 104 are provided above the keel 103. The bottom width of the pressing blocks 104 is smaller than that of the keel 103, so that the bottom of the pressing blocks 104 cannot completely cover the keel 103, leaving a portion of the upper surface of the keel 103 to support the photovoltaic module 105. A horizontal protrusion 1041 is provided on the top of the pressing blocks 104. The lower surface of the horizontal protrusion 1041 is parallel to the upper surface of the keel 103. In this way, a clamping track is formed between the pressing blocks 104 and the area on the top of the keel 103 that protrudes from the pressing blocks 104. The two ends of the photovoltaic module 105 are respectively embedded in the two adjacent opposing clamping tracks, thereby installing the photovoltaic module 105 on the bracket. The pressing block 104 and the keel 103 are fixed by a bolt groove 1031 passing through the pressing block 104 and the top of the keel 103. Specifically, the bolt groove 1031 at the top of the keel 103 has a similar structure to the bolt groove 1031 at the bottom, and the opening width is larger than the screw diameter and smaller than the bolt head width, and the groove width is larger than the bolt head width. In this way, the head of the bolt is placed in the bolt groove 1031, and the screw protrudes from the top of the keel 103 and passes through the pressing block 104. The bolt is then tightened with a nut above the pressing block 104, thereby fixing the pressing block 104 above the keel 103, and the photovoltaic module 105 is clamped by using the horizontal protrusions 1041 set at both ends of the top of the pressing block 104 and the upper surface of the keel 103.

[0034] In an embodiment of the present utility model, bolt mounting holes are opened on the upper surface of the air tower 102, and bolts are fixed inside the bolt mounting holes through chemical hoses inside the bolt mounting holes, so that the installation effect between the implant structure 101 and the air tower 102 is equivalent to that of embedded parts, thereby firmly fixing the implant structure 101 above the air tower 102, and then the keel 103 and the pressure block 104 are installed above the multiple installation rails formed by the implant structure 101 to form a clamping rail for installing the photovoltaic module 105. Based on this, the embodiment of the present invention uses a chemical hose to ensure that the bolts at the bottom of the implant structure 101 can be firmly fixed in the bolt mounting holes opened on the upper surface of the air tower 102, so that the implant structure 101 and the air tower 102 can achieve a fixing effect equivalent to that of embedded parts. Thereafter, the keel 103 and the pressure block 104 are installed above the implant structure 101 to form a clamping track for installing the photovoltaic component 105. In this way, there is no need to set up concrete pier counterweights to fix the photovoltaic mounting bracket, which effectively reduces the weight of the photovoltaic mounting bracket and avoids the collapse of the photovoltaic bracket due to the weight of the air tower 102.

[0035] Reference Figure 2In one embodiment, the first connecting structure includes a first connecting plate 201 fixed to the support plate 1012 and a second connecting plate 202 fixed to the fixing plate 1011. The first connecting plate 201 is provided with a first bolt hole 204, and the second connecting plate 202 is provided with a second strip-shaped hollow portion 203. The length of the second strip-shaped hollow portion 203 is greater than the aperture of the bolt hole, and the width of the second strip-shaped hollow portion 203 is equal to the aperture of the first bolt hole 204. The first connecting plate 201 and the second connecting plate 202 are fixed by bolts passing through the first bolt hole 204 and the second strip-shaped hollow portion 203. It is understood that the first connecting plate 201 and the support plate 1012 can be integrally formed. This increases the strength of the connection between the first connecting plate 201 and the support plate 1012. The first connecting plate 201 and the support plate 1012 are perpendicular to each other. Thus, the pressure on the support plate 1012 is applied perpendicularly to the first connecting plate 201, preventing the support plate 1012 and the first connecting plate 201 from further bending and deforming due to the pressure applied by the support plate 1012, which would cause deformation of the bracket. Similarly, the second connecting plate 202 and the fixing plate 1011 can also be integrally formed and perpendicular to each other. It is understandable that the length direction of the second strip-shaped hollow portion 203 is along the vertical direction. In this way, when the first connecting plate 201 and the second connecting plate 202 are fixed by the bolts passing through the first bolt hole 204 and the second regulating hollow portion, the relative position between the first connecting plate 201 and the second connecting plate 202 can be changed by adjusting the overlapping area of ​​the first bolt hole 204 and the second strip-shaped hollow portion 203, thereby reserving a certain adjustable range for the upper surface height of the support plate 1012. When installing the photovoltaic module 105, the installation height of the photovoltaic module 105 can be adjusted according to actual needs. In addition, when there are raised or recessed areas on the upper surface of the air tower 102, the height of each support plate 1012 can also be adjusted so that the upper surface of each keel 103, that is, the lower surface of the clamping rail, is in the same plane, ensuring that the two ends of the photovoltaic module 105 can be embedded in the two adjacent clamping rails.

[0036] Reference Figure 3 In one embodiment, the pressing block 104 includes a center column 301 and a horizontal protrusion 1041. The lower surface of the horizontal protrusion 1041 is perpendicular to the outer wall of the center column 301. The width of the center column 301 is smaller than the width of the keel 103. The center column 301 is hollowed out to form a bolt transmission area 303. The head of the bolt is fixed to the bolt groove 1031 at the top of the keel 103. The screw is passed through the bolt transmission area 303 and is fixed by a nut set above the pressing block 104. Figure 3The top of the pressing block 104 may be provided with a single horizontal protrusion 1041 protruding in the horizontal direction, or may be provided with two horizontal protrusions 1041 protruding on opposite sides in the horizontal direction. Specifically, the top of the pressing block 104 provided above the keels on both sides of the edge is provided with a single horizontal protrusion 1041, while the pressing block 104 provided above the keel 103 of the middle mounting track is provided with two horizontal protrusions 1041 protruding on opposite sides in the horizontal direction, so as to form clamping tracks on both sides to clamp the photovoltaic modules 105 on both sides of the pressing block 104 respectively. The center column 301 may be cylindrical, with its interior hollowed out and penetrated to form a bolt transmission area 303. The bolt transmission area 303 may be cylindrical, and the diameter of the bolt transmission area 303 is larger than the diameter of the bolt screw and smaller than the width of the nut.

[0037] Reference Figure 4 In one embodiment, the keel 103 includes a left side plate 401, a right side plate 402, and a second connecting structure 403 connecting the left side plate 401 and the right side plate 402. The bottoms of the left side plate 401 and the right side plate 402 are both provided with bottom bending portions 405 bent in opposite directions, and the tops of the left side plate 401 and the right side plate 402 are both provided with top bending portions 404 bent in opposite directions. The second connecting structure 403 includes a first connecting bridge 4031 and a second connecting bridge 4032. The two ends of the first connecting bridge 4031 are respectively fixed to the left side plate 401. The bottom bent portion 405 of the left panel 401 and the bottom bent portion 405 of the right panel 402 are fixed to the left panel 401 and the right panel 402. The bottom bent portion 405 at least partially protrudes from the connection point between the first connecting bridge 4031 and the bottom bent portion 405. The two ends of the second connecting bridge 4032 are respectively fixed to the top bent portion 404 of the left panel 401 and the top bent portions 404 of all the right panels 402. The top bent portion 404 at least partially protrudes from the connection point between the second connecting bridge 4032 and the top bent portion 404. The first connecting bridge 4031 and the second connecting bridge 4032 are rigidly fixed to each other. Specifically, the top bent portions 404 of the left panel 401 and the right panel 402 do not contact each other. Therefore, a gap is left between the left panel 401 and the right panel 402 as the opening of the bolt slot 1031. Similarly, the bottom bent portions 405 of the left panel 401 and the right panel 402 do not contact each other. The center of the first connecting bridge 4031 and the second connecting bridge 4032 is recessed toward the center of the keel 103, forming a bolt slot 1031. The bottom bent portion 405 at least partially protrudes from the connection point between the first connecting bridge 4031 and the bottom bent portion 405. As a result, the distance between the two endpoints of the first connecting bridge 4031 is greater than the distance between the two endpoints of the bottom bent portions 405. In other words, the width of the bolt slot 1031 is greater than the opening width of the bolt slot 1031. This allows the head of a bolt to be placed in the bolt slot 1031 without falling out. Similarly, the top bent portion 404 also at least partially protrudes from the connection point between the second connecting bridge 4032 and the top bent portion 404, forming a bolt slot 1031 with an opening width less than the slot width.

[0038] In one embodiment, the chemical hose contains at least one of vinyl resin, epoxy resin, and phenolic resin. Vinyl resin, epoxy resin, and phenolic resin are all thermosetting plastics with excellent adhesive properties. After reacting with a curing agent, they can form a relatively hard plastic material, thereby securely securing the bolts at the bottom of the fixing plate 1011 in the bolt mounting holes, thereby securely mounting the implant structure 101 above the air tower 102.

[0039] In one embodiment, at least one of the implant structure 101, the keel 103, and the pressing block 104 is made of AL6063-T5 aluminum. AL6063-T5 aluminum has a density of 2.71 tons per cubic meter and a hardness of 8HW. While being able to maintain good deformation, it has a lower density. Compared to stainless steel brackets, while being able to effectively support the photovoltaic modules 105, it effectively reduces the pressure on the air tower 102 caused by the bracket's own weight, effectively preventing the air tower 102 from collapsing due to the bracket's weight.

[0040] In one embodiment, the surfaces of the implant structure 101, keel 103, and compact 104 are covered with an oxide film having a thickness of no less than 15 microns. By providing the surfaces of the implant structure 101, keel 103, and compact 104 with an oxide film having a thickness of no less than 15 microns, the implant structure 101, keel 103, and compact 104 are passivated, thereby preventing corrosion or oxidation of the implant structure 101, keel 103, and compact 104, which could reduce the service life of the photovoltaic mounting bracket.

[0041] In one embodiment, the thickness of the plates comprising the implant structure 101, keel 103, and pressing block 104 is no less than 2 mm. This prevents the thickness of the plates comprising the implant structure 101, keel 103, and pressing block 104 from being too thin, which could result in insufficient strength of the bracket itself and deformation under the pressure of the photovoltaic module 105.

[0042] Reference Figure 3 and Figure 4 In one embodiment, both ends of the top edge of the keel 103 and the top edge of the pressing block 104 are provided with rounded areas. Based on this, by rounding the edges of the keel 103 and the top edge of the pressing block 104, sharp corners are eliminated and potential safety hazards caused by them are reduced.

[0043] Reference Figure 2In one embodiment, the connection between the fixing plate 1011 and the first connecting plate 201, and the connection between the support plate 1012 and the second connecting plate 202 are all provided with rounded areas. As structures supporting the weight of the photovoltaic bracket and photovoltaic module 105, the fixing plate 1011, the first connecting plate 201, the second connecting plate 202, and the support plate 1012 need to withstand greater stress at their corners. By providing rounded areas at the connection between the fixing plate 1011 and the first connecting plate 201, and at the connection between the support plate 1012 and the second connecting plate 202, the stress at these two locations can be dispersed, preventing deformation and damage to the structure.
