Description

Technical Field

[0001] This invention relates to the field of power support technology, specifically to a monopile ground support with excellent torsional resistance. Background Technology

[0002] In the era of booming renewable energy development, mountain power plants, with their abundant land resources and favorable sunlight conditions, have become an important part of the photovoltaic power generation field. However, the terrain where mountain power plants are located is often extremely complex, with crisscrossing gullies and significant slope undulations. Under such terrain conditions, traditional large-array support structures face many significant challenges.

[0003] In mountainous environments, leveling the site is no easy task. Creating a suitable installation foundation for the large-scale array support requires extensive site excavation. This necessitates the use of substantial machinery and resources, as well as significant manpower and material investment. Furthermore, the excavation process damages the original vegetation and soil structure, leading to environmental problems such as soil erosion. In addition, while traditional large-scale array support structures possess strong structural integrity, their adjustment flexibility is extremely limited. When faced with steep slopes, undulating terrain, or fragmented landforms, they cannot adapt flexibly to changes in the terrain, making it difficult to perfectly match complex topography. This results in some areas failing to fully utilize solar resources, reducing the overall power plant's power generation efficiency.

[0004] Monopile small array supports have solved the problems faced by traditional large array supports in mountainous power stations. They feature single-point support and flexible deployment. Monopile small array supports do not require large-scale site leveling; photovoltaic modules can be installed simply by driving a single pile into a suitable location. However, in mountainous environments, the supports must not only bear the weight of the photovoltaic modules and conventional loads such as wind, but also additional torque forces generated by factors such as terrain inclination and uneven foundation settlement. The structural design of traditional monopile supports focuses on vertical bearing capacity, and long-term exposure to torque forces can easily lead to pile torsion and top bending. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a monopile ground support with excellent torsional resistance, solving the problem that traditional monopile supports are prone to pile twisting and top bending when subjected to long-term torque.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a monopile ground support with excellent torsional resistance, comprising a fixed rod, a main rod fixedly connected to the top of the fixed rod, an installation frame fixedly connected to the top of the main rod, a central beam bolted to the outer wall of the installation frame, a polygonal main frame bolted to the outer wall of the central beam, at least two diagonal tie rods connected to the outer wall of the main rod, one end of the diagonal tie rod bolted to the main rod, the other end of the diagonal tie rod bolted to the outer wall of the polygonal main frame, and purlins bolted to the upper surface of the polygonal main frame.

[0007] The above scheme utilizes a polygonal main frame and diagonal braces to form a polygonal main beam design combined with an umbrella-shaped support structure. This achieves multi-point connection, constructs a stable force-bearing system, disperses and transmits forces, avoids stress concentration, improves torsional resistance, and better resists complex torsional forces in mountainous terrain. The "polygonal + central beam" design shortens the purlin span / cantilever length, making the purlin stress more rational, reducing bending moments, lowering the risk of deformation and damage, and enhancing the overall structural stability of the support. The entire support forms a biomimetic umbrella-shaped structure, with each component working synergistically to rationally distribute and transmit forces in different directions, ensuring high strength to withstand the weight of photovoltaic modules and external wind and snow loads, further strengthening torsional resistance and ensuring stable and reliable operation under complex conditions. Modular assembly and terrain adaptation: Modular assembly forms a small array that can be flexibly adjusted according to the undulating slope and varied terrain of the mountains. Each module can independently adapt to local terrain, improving the adaptability of mountain installation and reducing construction difficulty.

[0008] Preferably, the bottom end of the fixing rod is provided with an installation mechanism, and the installation mechanism is connected to a base.

[0009] Preferably, the installation mechanism includes a fixing plate, which is fixedly connected to the bottom end of the fixing rod. A sleeve is slidably connected to the outer wall of the fixing plate. A top cover is bolted to the upper surface of the sleeve, and the lower surface of the sleeve is fixedly connected to the upper surface of the base.

[0010] Preferably, rubber pads are provided on both the upper and lower surfaces of the fixing plate, with the upper rubber pad located between the fixing plate and the top cover, and the lower rubber pad located between the fixing plate and the base.

[0011] Preferably, springs are provided on both the upper and lower surfaces of the fixing plate. The top end of the upper spring is fixedly connected to the lower surface of the top cover, and the bottom end of the upper spring is fixedly connected to the upper surface of the fixing plate. The top end of the lower spring is fixedly connected to the lower surface of the fixing plate, and the bottom end of the lower spring is fixedly connected to the upper surface of the base.

[0012] Preferably, the outer wall of the fixing rod is connected to at least two sets of connecting rods. One end of the connecting rod is rotatably connected to the fixing rod, and the other end of the connecting rod is rotatably connected to a support leg. A cutting pin is slidably connected inside the support leg, and a pin head is fixedly connected to the upper surface of the cutting pin.

[0013] Preferably, the outer wall of the nail head is rotatably connected to a handle.

[0014] Preferably, a limiting block is fixedly connected to the outer wall of the fixed rod, and the two limiting blocks can fit against the outer wall of the connecting rod.

[0015] Preferably, the outer wall of the limiting block is rotatably connected to a threaded rod, and the outer wall of the threaded rod is threadedly connected to a nut.

[0016] Preferably, the outer wall of the fixing rod is fixedly connected with a strap, and two adjacent straps are respectively fixedly connected with a male buckle and a female buckle.

[0017] Working Principle: This invention provides a monopile ground support with excellent torsional resistance. Its structure includes a fixed rod, with a main rod and mounting frame sequentially connected to the top. A central beam is bolted to the outer wall of the mounting frame, and a polygonal main frame is bolted to the outer wall of the central beam. At least two diagonal tie rods are connected to the outer wall of the main rod, one end of which is bolted to the main rod, and the other end is bolted to the outer wall of the polygonal main frame. Purlins are bolted to the upper surface of the polygonal main frame. The core advantage of this support lies in its modular combination and flexible terrain adaptability. It can form small arrays through modular combinations, flexibly adjusting the combination according to the undulating slope and varied terrain. Each module can independently adapt to local terrain, and different module combinations can address complex landforms, improving installation adaptability in mountainous environments and reducing construction difficulty. Simultaneously, a single array can install multiple photovoltaic modules, increasing installed capacity, reducing the number of support arrays and pile foundations, lowering material costs, workload, construction period, and overall expenses, resulting in high economic efficiency.

[0018] The polygonal main frame and diagonal braces work together to form a polygonal main beam combined with an umbrella-shaped support structure. The polygonal main frame, with its polygonal design, works in conjunction with the umbrella-shaped support structure to achieve multi-point connections between the diagonal braces and the bottom of the main beam, constructing a stable load-bearing system. When the support is subjected to torsional forces, the force can be distributed and transferred through multiple connection points, avoiding stress concentration, improving torsional resistance, and enabling it to better resist torsional forces in complex mountainous environments. Furthermore, the "polygonal + center beam" design (a combination of the polygonal main frame and the center beam) shortens the purlin span / cantilever length, optimizing the load-bearing structure. Compared to a "circular" main beam, the polygonal main frame reduces the cantilever length of the outermost purlin of the fixed components, and the "center beam" design halves the purlin span, making the purlin stress more rational, reducing bending moments, lowering the risk of deformation and damage, and enhancing the overall structural stability of the support. The entire support structure forms a good spatial structural force system with a biomimetic umbrella-shaped structure. Each component works together to bear the load, rationally distributing and transmitting forces in different directions to ensure that the support has high strength and can withstand the weight of photovoltaic modules as well as external wind loads, snow loads, etc., further enhancing torsional resistance and ensuring stable and reliable operation under complex working conditions.

[0019] An installation mechanism is installed at the bottom of the fixed rod, connecting to a base. The base directly contacts the ground and can be partially buried underground or fixed by pouring concrete columns. The installation mechanism includes a fixing plate, fixedly connected to the bottom of the fixed rod, with a sleeve slidingly connected to its outer wall. A top cover is bolted to the upper surface of the sleeve, and the lower surface is fixedly connected to the upper surface of the base. During installation, the top cover is removed, the fixed rod and fixing plate are inserted into the sleeve, the two halves of the top cover are aligned, and bolted to the upper surface of the sleeve, thus fixing the fixed rod and fixing plate for easy replacement and maintenance later. Rubber pads or springs are installed on both the upper and lower surfaces of the fixing plate. The upper rubber pad or spring is located between the fixing plate and the top cover, and the lower one is located between the fixing plate and the base. The rubber pads can absorb vibration energy, effectively coping with dynamic loads such as wind, earthquakes, and vibrations, reducing structural damage and fatigue risk; the springs have strong load-bearing capacity, good linear stiffness characteristics, almost no creep, and good environmental resistance.

[0020] The outer wall of the fixed rod is connected to at least two sets of connecting rods. One end is rotatably connected to the fixed rod, and the other end is rotatably connected to the support leg. A slidable insert pin is connected inside the support leg, and a pin head is fixedly connected to the upper surface of the insert pin. A handle is rotatably connected to the outer wall of the pin head. When using the connecting rod, rotate it down to bring the support leg into contact with the ground. Select the insert pin, insert it into the support leg, and hammer the pin head to drive it into the ground for fixation. The connecting rods are usually symmetrically arranged to provide better auxiliary support. The handle facilitates the removal of the insert pin, and the insert pin, pin head, and handle are modularly designed for easy replacement. A limiting block is fixedly connected to the outer wall of the fixed rod, and the two limiting blocks can fit against the outer wall of the connecting rod. A threaded rod is rotatably connected to the outer wall of the limiting block, and a nut is threaded onto its outer wall. During transport, rotate the connecting rod until it aligns with the fixing rod and is positioned between the two limit blocks. Rotate to lift the threaded rod, then rotate it again until it blocks the outside of the connecting rod. Tighten the nut to secure it by applying friction. To lower the connecting rod, loosen the nut and rotate and lift the threaded rod. Alternatively, the connecting rod can be secured with straps. The straps are fixed to the outer wall of the fixing rod, and two adjacent straps are used to secure the male and female buckles respectively. After retracting the connecting rod, tighten the straps to engage the male and female buckles. Disengaging the male and female buckles releases the connecting rod.

[0021] This invention provides a monopile ground support with excellent torsional resistance. It has the following beneficial effects:

[0022] 1. This invention forms a stable force-bearing system through the cooperation of a polygonal main frame and diagonal braces, enhancing torsional resistance; it adopts a "polygonal + central beam" design to optimize the force-bearing structure and reduce the risk of purlin deformation and damage; the entire support has a biomimetic umbrella-shaped structure, with each component working together to rationally distribute and transmit force, strengthening torsional resistance and ensuring stability and reliability under complex working conditions; it can also adopt modular combination to form a small array, which can flexibly adapt to the varied terrain of mountainous areas and reduce construction difficulty; a single array can be equipped with multiple components to increase the installed capacity, and with the same installed capacity, the number of support arrays and pile foundations is reduced, reducing costs, shortening the cycle, and achieving high economic efficiency.

[0023] 2. The installation mechanism of this invention achieves a fixed connection between the fixing rod and the base through a fixing plate, sleeve and top cover, which facilitates later replacement and maintenance; by setting rubber pads or springs on the upper and lower surfaces of the fixing plate, vibration energy can be absorbed, effectively cope with dynamic loads such as wind, earthquakes and vibrations, reduce structural damage and reduce fatigue risk.

[0024] 3. This invention uses a connecting rod connected to the outer wall of a fixed rod. The connecting rod rotates and lowers, allowing the support feet to contact the ground and the cutting nail to be inserted into the ground. This enhances the stability of the fixed rod, and the symmetrical arrangement of the connecting rods provides better auxiliary support. The outer wall of the nail head is rotatably connected to a handle, making it easy to remove the cutting nail. The handle is rotatably connected to the nail head, and when hammering the nail head, it can be rotated to one side to avoid interference. The modular design of the cutting nail, nail head, and handle makes it easy to replace.

[0025] 4. The limiting block on the outer wall of the fixing rod of this invention can restrict the rotation of the connecting rod, and the threaded rod and nut can fix the connecting rod; or the strap, male buckle and female buckle on the outer wall of the fixing rod can tighten the retracted connecting rod, fix the connecting rod to prevent it from rotating when lowered, and release the connecting rod by disengaging from the male buckle and female buckle. This facilitates the retraction of the connecting rod during transportation. Attached Figure Description

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figure 1 - Appendix Figure 5This invention provides a monopile ground support with excellent torsional resistance, including a fixed rod 1, a main rod 2 fixedly connected to the top of the fixed rod 1, an installation frame 5 fixedly connected to the top of the main rod 2, a central beam 3 bolted to the outer wall of the installation frame 5, a polygonal main frame 4 bolted to the outer wall of the central beam 3, at least two diagonal tie rods 6 connected to the outer wall of the main rod 2, one end of the diagonal tie rod 6 bolted to the main rod 2, and the other end of the diagonal tie rod 6 bolted to the outer wall of the polygonal main frame 4, and purlins 7 bolted to the upper surface of the polygonal main frame 4.

[0037] Specifically, this invention provides a monopile ground support with excellent torsional resistance, whose core advantages lie in its modular combination and flexible terrain adaptability. Firstly, this invention allows for modular combination, flexibly adapting to complex terrain: this support forms small arrays through modular combination, which can be flexibly adjusted and combined according to the undulating slope and varied terrain conditions of mountains. Each module can independently adapt to local terrain, and through the combination of different modules, it easily copes with the complex topography of mountainous areas. Compared with large array supports, it greatly improves the installation adaptability in mountainous environments and reduces the construction difficulty caused by terrain limitations. Secondly, it increases the installed capacity of a single array and reduces overall costs: compared with traditional monopile small array supports, this support can install multiple photovoltaic modules in a single array, significantly increasing the installed capacity of a single array. With the same installed capacity, the number of support arrays required is greatly reduced, and the corresponding number of piles is also reduced. This not only reduces the use of raw materials such as steel, lowering material costs, but also reduces the workload during construction and installation, shortens the construction cycle, and thus reduces the overall construction and installation costs, exhibiting high economic efficiency. Furthermore, the combination of the polygonal main frame 4 and the diagonal brace 6 forms a polygonal design of the main beam and an umbrella-shaped support structure, enhancing torsional resistance. The polygonal main frame 4 adopts a polygonal design, which, combined with the umbrella-shaped support structure, enables multi-point connection between the diagonal brace 6 and the bottom of the main beam 2. This multi-point connection method constructs a stable force-bearing system. When the support is subjected to torsional force, the force can be distributed and transmitted through multiple connection points, avoiding stress concentration in a certain part, effectively improving the torsional resistance of the support, and enabling it to better resist the influence of various torsional forces in complex mountainous environments. This application adopts a "polygonal + middle beam 3" design (i.e., a combination of polygonal main frame 4 and middle beam 3) to shorten the span / cantilever length of the purlin 7 and optimize the force-bearing structure. The polygonal main frame 4 adopts a "polygonal" design, which, compared to a "circular" main beam, effectively reduces the cantilever length of the outermost purlin 7 of the fixed component. The "middle beam 3" design halves the span of the purlin 7. The shorter cantilever length and smaller purlin 7 span make the stress distribution of purlin 7 more reasonable, reducing the bending moment of purlin 7, lowering the risk of deformation and damage to purlin 7, and further enhancing the overall structural stability of the support. The entire support structure of this application forms a better spatial structural force system, a biomimetic umbrella-shaped structure, with each component working together to share the load. This spatial structure can rationally distribute and transmit forces from different directions, ensuring not only that the support has high strength and can withstand the weight of the photovoltaic modules themselves as well as external wind loads, snow loads, etc., but also further enhancing its torsional resistance, ensuring that the support maintains a stable and reliable working state under various complex working conditions.

[0038] Please see the appendix Figure 1 The bottom end of the fixed rod 1 is provided with an installation mechanism 8, and the installation mechanism 8 is connected to a base 9.

[0039] Specifically, this application uses an installation mechanism 8 and a base 9 to fix the structure from the bottom. The base 9 is in direct contact with the ground. Part of the base 9 can be buried underground, or it can be fixed by pouring concrete columns. There are already many ways to implement the foundation, so this application will not describe them in detail.

[0040] Please see the appendix Figure 7 - Appendix Figure 8 The installation mechanism 8 includes a fixing plate 801, which is fixedly connected to the bottom end of the fixing rod 1. A sleeve 802 is slidably connected to the outer wall of the fixing plate 801. A top cover 803 is bolted to the upper surface of the sleeve 802. The lower surface of the sleeve 802 is fixedly connected to the upper surface of the base 9.

[0041] Specifically, this application uses the installation mechanism 8 to fix the fixing rod 1 to the base 9, thereby fixing the base 9 to the sleeve 802. If it is a concrete foundation, it is fixed by pre-embedded parts and then by welding or other methods. The upper surface of the sleeve 802 is provided with a top cover 803. When the fixing rod 1 is installed, the top cover 803 can be removed, and the fixing rod 1 and the fixing plate 801 can be inserted into the inside of the sleeve 802. After aligning the two halves of the top cover 803, the bolts are installed on the upper surface of the sleeve 802, and the fixing rod 1 and the fixing plate 801 can be installed and fixed. This connection method is convenient for later replacement and maintenance.

[0042] Please see the appendix Figure 7 Rubber pads 811 are provided on both the upper and lower surfaces of the fixing plate 801. The upper rubber pad 811 is located between the fixing plate 801 and the top cover 803, and the lower rubber pad 811 is located between the fixing plate 801 and the base 9.

[0043] Specifically, since the support of this application may face complex environments, long-term vibration loads may lead to structural fatigue failure or instability. Therefore, rubber pads 811 are added for buffering. In this embodiment, rubber pads 811 are not added above or below the fixing plate 801. The rubber pads 811 can absorb vibration energy, effectively cope with dynamic loads such as wind, earthquakes, and vibrations, reduce structural damage, and reduce fatigue risk.

[0044] Example 2:

[0045] Please see the appendix Figure 8 In this embodiment, another structure is provided in the above embodiment: springs 821 are provided on both the upper and lower surfaces of the fixing plate 801. The top end of the upper spring 821 is fixedly connected to the lower surface of the top cover 803, the bottom end of the upper spring 821 is fixedly connected to the upper surface of the fixing plate 801, the top end of the lower spring 821 is fixedly connected to the lower surface of the fixing plate 801, and the bottom end of the lower spring 821 is fixedly connected to the upper surface of the base 9.

[0046] Specifically, in this embodiment, spring 821 is used instead of rubber pad 811. Spring 821 has strong load-bearing capacity, good stiffness linearity, almost no creep, and good environmental resistance.

[0047] Please see the appendix Figure 7 - Appendix Figure 8 At least two sets of connecting rods 10 are connected to the outer wall of the fixed rod 1. One end of the connecting rod 10 is rotatably connected to the fixed rod 1, and the other end of the connecting rod 10 is rotatably connected to the support leg 11. The support leg 11 is slidably connected to the insert pin 12, and the upper surface of the insert pin 12 is fixedly connected to the nail head 13.

[0048] Specifically, to enhance the stability of the fixed rod 1, a connecting rod 10 can be added. The connecting rod 10 pulls or supports from the side, further enhancing the stability of the bracket. When using the connecting rod 10, rotate and lower the connecting rod 10 so that the support leg 11 is in contact with the ground. Select the insert nail 12 and insert it into the inside of the support leg 11. Hammer the nail head 13 to insert the insert nail 12 into the ground, thereby completing the fixation. Usually, the connecting rods 10 are symmetrically arranged, which can provide a better auxiliary support effect.

[0049] Please see the appendix Figure 7 A handle 14 is rotatably connected to the outer wall of the nail head 13.

[0050] Specifically, in this application, the fixing rod 1 is detachable and replaceable, so the cutting nail 12 needs to be pulled out. By adding a handle 14 to the outer wall of the nail head 13, when it is necessary to remove the cutting nail 12, the pulling force can be easily applied through the handle 14, which is convenient for operation. Since the handle 14 rotates with the nail head 13, when hammering the nail head 13, the handle 14 can be rotated to one side to avoid interfering with the hammering operation. Moreover, the cutting nail 12 is slidably connected to the support leg 11. The cutting nail 12, nail head 13 and handle 14 are a modular design, which is convenient for replacement and use.

[0051] Please see the appendix Figure 6 The outer wall of the fixed rod 1 is fixedly connected to a limiting block 15, and the two limiting blocks 15 can fit against the outer wall of the connecting rod 10; the outer wall of the limiting block 15 is rotatably connected to a threaded rod 16, and the outer wall of the threaded rod 16 is threadedly connected to a nut 17.

[0052] Specifically, in this application, the connecting rod 10 is rotatable. For convenient transportation, the connecting rod 10 can be rotated to fit against the fixing rod 1. After rotation, the connecting rod 10 is located between the two limiting blocks 15. The limiting blocks 15 restrict the connecting rod 10. It can then be fixed by the threaded rod 16 and the nut 17. First, the threaded rod 16 is rotated and lifted to facilitate rotating the connecting rod 10 between the two limiting blocks 15. Then, the threaded rod 16 is rotated to block the outside of the connecting rod 10. At this time, the nut 17 is tightened. The nut 17 is pressed tightly against the outer wall of the limiting block 15, thereby completing the fixation by increasing the friction. When it is necessary to lower the connecting rod 10, the nut 17 can be loosened first, and the threaded rod 16 can be rotated and lifted. At this time, the connecting rod 10 can rotate arbitrarily.

[0053] Example 3:

[0054] Please see the appendix Figure 8 In this embodiment, another structure is provided in the above embodiment: the outer wall of the fixing rod 1 is fixedly connected with a strap 18, and two adjacent straps 18 are respectively fixedly connected with a male buckle 19 and a female buckle 20.

[0055] Specifically, the connecting rod 10 can also be fixed by the strap 18. After the connecting rod 10 is retracted, the strap 18 is used to tighten the retracted connecting rod 10. Then, the male buckle 19 and the female buckle 20 are engaged. At this time, the strap 18, the male buckle 19 and the female buckle 20 tighten the connecting rod 10 on the outside of the fixing rod 1, and the connecting rod 10 cannot be lowered and rotated. The connecting rod 10 can be released by disengaging the male buckle 19 and the female buckle 20.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
