Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a photovoltaic support foundation and a photovoltaic power generation system. Background Art

[0002] Solar photovoltaic modules are a clean and efficient energy conversion device, mainly made of semiconductor silicon and other materials. Their power generation process is simple, with no mechanical rotating parts, no need for fuel, and no emissions of any gas. They have the advantages of being noiseless, pollution-free, easy to maintain, and stable in operation. Therefore, they have been increasingly widely used.

[0003] During the construction of the photovoltaic support foundation in the prior art, it is necessary to first drill a pile hole on the rock and soil slope, and then place a steel cage in the pile hole after the pile hole is formed. After the steel cage is positioned in the pile hole, pour the evenly mixed concrete into the pile hole and vibrate the concrete to make it dense. After the concrete strength in the pile hole reaches the specification requirements, the pedestal steel bars with embedded anchor bolts are fixed on the top of the pile foundation, and finally the concrete of the pedestal is poured. However, the height of the pedestal made by pouring concrete often has a certain gap with the design height. Once the height of the pedestal deviates, the subsequent step of installing the columns on the pedestal becomes difficult to carry out. This results in the operator having to repeatedly pour concrete and measure the height during the construction of the photovoltaic support foundation until the height of the pedestal reaches the design height, making the construction process cumbersome. Utility Model Content

[0004] In view of this, the utility model provides a photovoltaic bracket foundation and a photovoltaic power generation system to solve the problem of complicated photovoltaic bracket foundation construction process in the prior art.

[0005] In a first aspect, the present invention provides a photovoltaic support foundation, comprising:

[0006] A cylindrical pile is suitable for being buried in a pile hole. A first connecting hole is formed at the top of the cylindrical pile. The interior of the cylindrical pile and the space between the cylindrical pile and the pile hole are suitable for being filled with concrete.

[0007] The column is suitable for being inserted into the pile, and a second connecting hole is formed at the bottom end of the column. The first connecting hole and the second connecting hole are suitable for fasteners to pass through and connect the pile and the column. There are multiple first connecting holes and / or second connecting holes and they are spaced apart along the height direction.

[0008] Beneficial effects: The photovoltaic support foundation of the present invention is formed with a first connection hole and a second connection hole at the top of the cylinder pile and the bottom of the column, respectively. The first connection hole and the second connection hole are suitable for fasteners to pass through and connect the cylinder and the column. At least one of the first connection hole and the second connection hole is provided in plurality and spaced apart in the vertical direction. Therefore, the operator can adjust the height of the column by connecting different first connection holes with the second connection holes. Since the distance between two adjacent connection holes is fixed, when the column is connected to the cylinder pile, the operator only needs to measure the height of the cylinder pile once and select the appropriate first connection hole and the second connection hole for connection. This can ensure that the height of the photovoltaic support foundation meets the standard. The operator does not need to repeatedly measure the height of the base during the construction of the photovoltaic support foundation, which can effectively simplify the construction process.

[0009] In an optional embodiment, the column includes:

[0010] cylindrical body;

[0011] A plurality of reinforcing partitions are formed at the bottom of the cylindrical body and are spaced apart in the vertical direction.

[0012] Beneficial effects:

[0013] The reinforcing partition can be used to increase the strength of the bottom end of the column. Since the position where the column contacts the cylinder is subjected to greater force, the reinforcing partition of this embodiment can be used to improve the strength of the bottom end of the column without increasing the thickness of the column. It can ensure that the column has sufficient strength without excessively increasing the cost of the column.

[0014] In an optional embodiment, the top end of the column is connected to the cylindrical pile by welding.

[0015] Beneficial effect: Through such an arrangement, the column can be permanently fixed on the cylindrical pile.

[0016] In an optional embodiment, a plurality of pegs are formed on the outer circumference and / or inner circumference of the cylindrical pile.

[0017] Beneficial effect: The function of the stud is to increase the friction and bond strength between the steel pile and the concrete.

[0018] In an optional embodiment, the pile is a cylindrical structure, and a plurality of air holes communicating with the inside and outside of the pile are formed on the wall of the pile.

[0019] Beneficial effects:

[0020] After the operator fixes the pile in the pile hole, concrete needs to be poured into the pile and vibrated to make it dense. The gas inside the pile can be discharged to the outside of the cylinder through the air vent, which can make the soil after vibration more compact.

[0021] In an optional embodiment, the photovoltaic support foundation further includes:

[0022] The crossbeam is arranged at the top end of the column, extends in the horizontal direction, and is connected to the column in the middle. The crossbeam is suitable for supporting the photovoltaic panel.

[0023] In an optional embodiment, the photovoltaic support foundation further includes a diagonal brace, one end of the diagonal brace is connected to the column, and the other end is connected to the end of the beam.

[0024] Beneficial effects:

[0025] The diagonal braces can connect the ends of the beams to the columns to form a triangular stable structure to increase the connection strength between the beams and the columns.

[0026] In a second aspect, the present invention further provides a photovoltaic power generation system, further comprising:

[0027] The photovoltaic support foundation provided by the first aspect of the present utility model comprises a plurality of photovoltaic support foundations which are arranged at intervals;

[0028] A supporting cable connected between the beams of two adjacent photovoltaic support foundations;

[0029] The photovoltaic module is arranged on the supporting cables.

[0030] Beneficial effects:

[0031] The photovoltaic power generation system of the second aspect of the utility model includes or uses the photovoltaic bracket foundation of the first aspect of the utility model, and thus has its beneficial effect, namely, it can ensure that the operator only needs to measure the height of the pile once when the column is connected to the pile, and select the appropriate first connection hole and the second connection hole for connection, so as to ensure that the height of the photovoltaic bracket foundation meets the standard. The operator does not need to repeatedly measure the height of the base during the construction of the photovoltaic bracket foundation, which can effectively simplify the construction process.

[0032] In addition, the photovoltaic power generation system of the present invention fully utilizes the characteristics of the cable structure such as high strength, strong spanning capacity, and tensioning. By adopting a new type of pile foundation, this complex structure is conveniently applied to rugged mountain terrain, reducing the construction of construction platforms and roads on the slope, avoiding damage to the natural ecology of the slope, reducing construction costs, shortening the overall construction period, saving land resources, and having obvious economic, social and environmental benefits.

[0033] In an optional embodiment, a connecting structure is provided at the top end of the crossbeam, and the supporting cable is detachably connected to the connecting structure, and the connecting structure includes:

[0034] The U-shaped plate includes a first side plate, a second side plate, and a connecting plate, wherein the first side plate and the second side plate are respectively connected to two sides of the crossbeam, the connecting plate is located above the crossbeam and connected between the first side plate and the second side plate, and a third connecting hole and a fourth connecting hole are formed on the connecting plate;

[0035] The U-shaped bolt has two ends passing through the first connecting hole and the second connecting hole respectively, and is threadedly connected to the connecting plate. A passage is formed between the U-shaped plate and the U-shaped bolt, and the support cable passes through the passage. An anti-slip structure is formed at the end of the support cable, and the cross-sectional area of ​​the anti-slip structure is larger than the passage.

[0036] Beneficial effects:

[0037] A gap for accommodating the end of the U-bolt can be formed between the U-shaped plate and the top end of the beam. The operator can adjust the area of ​​the opening by adjusting the width of the U-shaped bolt passing through the U-shaped plate to allow different types of support cables to pass through the opening.

[0038] In an optional embodiment, there are multiple photovoltaic modules, and the multiple photovoltaic modules are arranged at intervals.

[0039] Beneficial Effects: Because the support cables are made of flexible materials with a certain strength, after the support cables are tensioned, they will inevitably produce a certain amount of downward deflection under the weight of the photovoltaic modules. Under the action of wind loads, the wind will exert an upward force or downward pressure on the photovoltaic modules, which can easily cause the photovoltaic modules to fluctuate upward or downward. In the photovoltaic power generation system of the present invention, multiple photovoltaic modules are arranged at intervals, which can prevent the edges of the photovoltaic modules from being squeezed against each other when the support cables are deformed, causing deformation or damage to the photovoltaic panel modules.

[0065] 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 drawings in the embodiments of the present invention. Obviously, the embodiments described 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.

[0066] like Figure 10 As shown, during the construction process of the photovoltaic support foundation in the prior art, it is necessary to first drill a pile hole 2' on the rock slope. After the pile hole 2' is formed, a steel cage 1' is placed in the pile hole 2'. After the steel cage 1' is positioned in the pile hole 2', the mixed concrete is poured into the pile hole 2' and the concrete is vibrated to make it dense. After the concrete strength in the pile hole 2' reaches the specification requirements, the base steel bar 301' fixed with pre-embedded anchor bolts is placed on the top of the pile foundation, and finally the concrete of the base 3' is poured. However, since the pouring process will cause a large error in the height of the base 3', once the height of the base 3' deviates, the subsequent step of installing the column 4' on the base 3' will be difficult to carry out. Therefore, once the height of the base 3' does not reach the designed height, the operator needs to pour concrete, vibrate to make it dense, measure the height, etc. again until the height of the base 3' meets the designed height. This results in the need to repeatedly measure the height of the base during the construction of the photovoltaic support foundation in the prior art, making the construction process cumbersome.

[0067] The following combination Figures 1 to 4 , describing the embodiments of the present utility model.

[0068] According to an embodiment of the present invention, on the one hand, a photovoltaic support base 100 is provided, such as Figure 1 As shown, it includes a pile 1 and a column 2. The pile 1 is suitable for being buried in a pile hole 200. A first connecting hole 101 is formed at the top of the pile 1. Concrete 10 is suitable for filling the inside of the pile 1 and between the pile 1 and the pile hole 200. A second connecting hole 201 is formed at the bottom of the column 2. Figure 2 and Figure 3 As shown, the first connecting hole 101 and the second connecting hole 201 are suitable for fasteners to pass through and connect the pile 1 and the column 2. There are multiple first connecting holes 101 and / or second connecting holes 201 and they are spaced apart in the height direction.

[0069] The photovoltaic support foundation 100 of the present invention is respectively formed with a first connection hole 101 and a second connection hole 201 at the top of the cylindrical pile 1 and the bottom of the column 2. The first connection hole 101 and the second connection hole 201 are suitable for fasteners to pass through and connect the cylindrical pile and the column 2. At least one of the first connection hole 101 and the second connection hole 201 is provided in a plurality and spaced apart in the vertical direction. Therefore, the operator can adjust the height of the column 2 by connecting different first connection holes 101 with the second connection hole 201. Since the distance between two adjacent connection holes is fixed, when the column 2 is connected to the cylindrical pile 1, the operator only needs to measure the height of the cylindrical pile 1 once and select the appropriate first connection hole 101 and the second connection hole 201 for connection. This can ensure that the height of the photovoltaic support foundation 100 meets the standard. The operator does not need to repeatedly measure the height of the base during the construction of the photovoltaic support foundation 100, which can effectively simplify the construction process.

[0070] The concrete 10 is preferably micro-expansive concrete 10, which can fully fill the space between the inner wall of the pile hole 200 and the outer wall of the steel pile, so that the rock, concrete 10 and the cylindrical pile 1 are bonded into a whole. The cylindrical pile 1 is preferably, but not limited to, a steel pile.

[0071] In one embodiment, Figure 2 As shown, the column 2 includes a cylindrical body 202 and a plurality of reinforcing partitions 203. The plurality of reinforcing partitions 203 are formed at the bottom of the cylindrical body 202 and are spaced apart in the vertical direction.

[0072] The reinforcing partition 203 can be used to increase the strength of the bottom end of the column 2. Since the position where the column 2 contacts the cylinder is subjected to greater force, the reinforcing partition 203 of this embodiment can be used to improve the strength of the bottom end of the column 2 without increasing the thickness of the column 2. It can ensure that the column 2 has sufficient strength without excessively increasing the cost of the column 2.

[0073] As a variant embodiment, a reinforcing rib surrounding the inner circumference and / or outer circumference of the column 2 is formed at the bottom of the column 2 .

[0074] As another alternative embodiment, the wall thickness of the bottom of the column 2 is greater than the wall thickness of the upper portion of the column 2 .

[0075] In one embodiment, the top end of the column 2 is welded to the cylindrical pile 1 , thereby permanently fixing the column 2 to the cylindrical pile 1 .

[0076] In one embodiment, Figure 4As shown, multiple studs 102 are formed on the outer and / or inner circumference of the pile 1. The studs 102 increase the friction and bond strength between the steel pile and the concrete 10. The studs 102 can be welded to the outer circumference of the cylinder, penetrated from the inside out through the wall of the pile 1, or integrally formed on the pile 1.

[0077] In one embodiment, the pile 1 is a cylindrical structure, and a plurality of air vents connecting the inside and outside of the pile 1 are formed on the wall of the pile 1. After the operator fixes the pile 1 in the pile hole 200, it is necessary to pour concrete 10 into the pile 1 and vibrate it to make it dense. The gas inside the pile 1 can be discharged to the outside of the cylinder through the air vents, which can make the soil after vibration more dense.

[0078] In one embodiment, the photovoltaic support foundation 100 further includes a crossbeam 3. The crossbeam 3 is disposed at the top of the column 2, extends horizontally, and is connected to the column 2 at its middle portion. The crossbeam 3 is suitable for supporting the photovoltaic panel.

[0079] In one embodiment, the photovoltaic support foundation 100 further includes a diagonal brace 4, one end of which is connected to the column 2 and the other end is connected to the end of the beam 3. The diagonal brace 4 can connect the end of the beam 3 to the column 2 to form a triangular stable structure, thereby increasing the connection strength between the beam 3 and the column 2.

[0080] To sum up, the photovoltaic bracket foundation 100 of the present invention can ensure that the operator only needs to measure the height of the pile 1 once when the column 2 is connected to the pile 1, and select the appropriate first connection hole 101 and the second connection hole 201 for connection, so as to ensure that the height of the photovoltaic bracket foundation 100 meets the standard. The operator does not need to repeatedly measure the height of the base during the construction of the photovoltaic bracket foundation 100, which can effectively simplify the construction process.

[0081] According to another embodiment of the present invention, a photovoltaic power generation system is provided, comprising a photovoltaic support base 100, support cables 5, and photovoltaic modules 6. The photovoltaic support base 100 is the photovoltaic support base 100 described in the first aspect of the present invention, and multiple photovoltaic support bases 100 are provided, spaced apart. The support cables 5 are connected between the crossbeams 3 of two adjacent photovoltaic support bases 100. The photovoltaic modules 6 are mounted on the support cables 5.

[0082] Next, the installation method of the photovoltaic support base 100 of the present invention is described:

[0083] First, a borehole is excavated to the designed depth. A cylindrical pile 1 with bolts 102 around its perimeter is placed into the pile hole 200, passing through the fully weathered tuff layer 8 and the strongly weathered tuff layer 9 (the strongly weathered tuff layer 9 can be replaced with a moderately weathered tuff layer). Fine aggregate concrete 10 with slightly expansive properties is poured into the pile hole 200 and into the interior of the steel pile, and then vibrated to compact the concrete. The top of the cylindrical pile 1 is raised above the ground to the designed height.

[0084] Then, the bottom end of the column 2 is inserted into the cylindrical pile 1, and the insertion length of the column 2 is adjusted according to the design requirements. After the adjustment is completed, the fasteners are sequentially passed through the first connecting hole 101 and the second connecting hole 201.

[0085] Finally, the top of the pile 1 is welded to the column 2.

[0086] According to an embodiment of the present invention, on the other hand, a photovoltaic power generation system is provided, comprising a photovoltaic support base 100, a support cable and a photovoltaic module. Figures 5 to 9 , describing the embodiments of the present utility model.

[0087] The photovoltaic support base 100 is the photovoltaic support base provided by the first aspect of the present invention. There are multiple photovoltaic support bases 100, which are arranged at intervals. The support cables 5 are connected between the crossbeams 3 of two adjacent photovoltaic support bases 100. The photovoltaic modules 6 are arranged on the support cables 5.

[0088] The photovoltaic power generation system of the second aspect of the present invention includes or uses the photovoltaic bracket foundation 100 of the first aspect of the present invention, and thus has its beneficial effect, namely, it can ensure that the operator only needs to measure the height of the pile 1 once when the column 2 is connected to the pile 1, and select the appropriate first connection hole 101 and the second connection hole 201 for connection, so as to ensure that the height of the photovoltaic bracket foundation 100 meets the standard. The operator does not need to repeatedly measure the height of the base during the construction of the photovoltaic bracket foundation 100, which can effectively simplify the construction process.

[0089] In addition, the photovoltaic power generation system of the present invention fully utilizes the characteristics of the cable structure such as high strength, strong spanning capacity, and tensioning. By adopting a new type of pile foundation, this complex structure is conveniently applied to rugged mountain terrain, reducing the construction of construction platforms and roads on the slope, avoiding damage to the natural ecology of the slope, reducing construction costs, shortening the overall construction period, saving land resources, and having obvious economic, social and environmental benefits.

[0090] Preferably, if Figure 5 and Figure 6 As shown, the ends of the supporting cables 5 are connected to the connecting structure on the ground to form inclined cables.

[0091] In one embodiment, a connection structure 7 is provided at the top end of the crossbeam 3 , and the supporting cable 5 is detachably connected to the connection structure 7 .

[0092] In one embodiment, Figure 7 、 Figure 8 and Figure 9 As shown, the connection structure 7 includes a U-shaped plate 701 and a U-shaped bolt 702. The U-shaped plate 701 includes a first side plate 7011, a second side plate 7012, and a connecting plate 7013. The first side plate 7011 and the second side plate 7012 are respectively connected to the two sides of the crossbeam 3. The connecting plate 7013 is located above the crossbeam 3 and connected between the first side plate 7011 and the second side plate 7012. A third connecting hole 7014 and a fourth connecting hole 7015 are formed on the connecting plate 7013. The two ends of the U-shaped bolt 702 pass through the first connecting hole 7014 and the second connecting hole 7015 respectively and are threadedly connected to the connecting plate 7013. A through hole is formed between the U-shaped plate 701 and the U-shaped bolt 702, through which the support cable 5 passes. The end of the support cable 5 is formed with an anti-slip structure, and the cross-sectional area of ​​the anti-slip structure is larger than the through hole.

[0093] Therefore, a gap can be formed between the U-shaped plate 701 and the top end of the beam 3 to accommodate the end of the U-shaped bolt 702. The operator can adjust the area of ​​the opening by adjusting the width of the U-shaped bolt 702 passing through the U-shaped plate 701 to allow different types of support cables 5 to pass through the opening.

[0094] In one embodiment, the anti-slip structure includes a P-type anchor 401 .

[0095] In one embodiment, there are multiple photovoltaic components 6 , and the multiple photovoltaic components 6 are arranged at intervals.

[0096] Since the support cable 5 is a flexible material with a certain strength, after the support cable 5 is tensioned, under the weight of the photovoltaic module 6, the support cable 5 will inevitably produce a certain downward deflection. Under the action of wind load, the wind will produce an upward force or downward pressure on the photovoltaic module 6, which can easily cause the module to produce an upward or downward undulating deformation. In the photovoltaic power generation system of the present invention, multiple photovoltaic modules 6 are arranged at intervals to prevent the edges of the photovoltaic modules 6 from being squeezed against each other when the support cable 5 is deformed, causing deformation or damage to the photovoltaic panel assembly. Preferably, a pressure block is also provided between two adjacent photovoltaic modules 6, which can prevent the distance between the two adjacent photovoltaic modules 6 from being reduced, thereby avoiding squeezing of the edges of the photovoltaic modules 6.

[0097] 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, and such modifications and variations shall fall within the scope defined by the appended claims.
