Description

Technical Field

[0001] This invention relates to the field of photovoltaic installation, and in particular to a prefabricated column photovoltaic fence. Background Technology

[0002] In the field of photovoltaic energy utilization, outdoor photovoltaic panels, as the core device for converting solar energy into electricity, are widely used in various ground-mounted power station projects. Their installation and fixation usually rely on supporting structures to achieve stable deployment. Among them, the support method of cement piles combined with precast columns has become the preferred solution for supporting photovoltaic panels in outdoor photovoltaic projects due to its advantages such as strong structural stability, adaptability to complex outdoor terrain, low total life cycle cost, and outstanding resistance to extreme environments. Cement piles are buried underground to provide a stable foundation, precast columns are inserted into the cement piles to form the main support structure, and photovoltaic panels are installed between adjacent precast columns, and fixed installation is achieved through clamping components.

[0003] Currently, existing photovoltaic panel clamping components used in this type of support structure still have many technical defects, making it difficult to meet the requirements of efficient and safe installation in actual engineering projects. On the one hand, existing clamping components generally lack effective buffer and deceleration structures. The clamping plate moves too fast during the clamping process, which can easily directly impact the surface of the photovoltaic panel, causing damage and affecting the service life and power generation efficiency of the photovoltaic panel. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention is proposed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a precast column photovoltaic wall, which includes cement piles buried underground, precast columns inserted into the cement piles, multiple precast columns, photovoltaic panels disposed between two precast columns, and clamping components disposed on the outer wall of the precast columns for installing photovoltaic panels. Two sets of clamping assemblies are arranged horizontally. Each clamping assembly includes a water platform disposed on the outer wall of the precast column, the water platform including a support platform, an abutment rod slidably installed with the support platform, a clamping plate disposed on the outer wall of the abutment rod, and a first elastic member disposed between the clamping plate and the support platform.

[0006] As a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, the support platform includes a first chamber for sliding of the abutment rod and a second chamber communicating with the first chamber, and the second chamber array is provided with multiple chambers.

[0007] In a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, the sum of the cross-sections of the plurality of second chambers is smaller than the cross-section of the first chamber.

[0008] As a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, the second chamber is provided with a second elastic element and a piston.

[0009] In a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, the piston and the bottom of the second chamber form a buffer chamber, and the buffer chamber is connected to the outside through a through hole.

[0010] As a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, one end of the abutment rod extends through the clamping plate, and the upper end of the clamping plate is provided with an inclined plate.

[0011] As a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, the end of the abutment rod near the clamping plate is chamfered to form a first oblique arc surface.

[0012] As a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, the distance between the two water platforms is greater than the installation thickness of the photovoltaic panels.

[0013] As a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, a baffle is detachably provided between the two water platforms.

[0014] As a preferred embodiment of the prefabricated column photovoltaic wall of the present invention, the outer wall of the baffle is provided with a first slider, and the outer wall of the water platform is provided with a first groove for the first slider to slide.

[0015] The beneficial effects of this invention are as follows: Through the cross-sectional design of the first and second chambers, the cooperation of the buffer chamber and the through hole, combined with the resistance of the second elastic element, a double-layer buffering effect is formed, preventing the clamping plate from sliding too fast and impacting the photovoltaic panel, effectively reducing damage to the photovoltaic panel surface; the design of the inclined plate of the clamping plate and the first inclined arc surface of the contact rod, combined with the photovoltaic panel's own weight, facilitates the rapid positioning and installation of the photovoltaic panel, reducing the difficulty of operation; the combination of double elastic elements and sealing structure not only ensures the photovoltaic panel is firmly clamped, but also provides safety for operators. The overall structural design is reasonable, and the installation and disassembly are convenient, improving the stability and practicality of the device. Attached Figure Description

Detailed Implementation

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0021] Example 1: Refer to Figures 1-8 This is the first embodiment of the present invention, which provides a prefabricated column photovoltaic wall.

[0022] Specifically, there are cement piles 10 buried underground, precast columns 20 inserted into the cement piles 10, multiple precast columns 20, photovoltaic panels A between two precast columns 20, and clamping components 30 on the outer wall of the precast columns 20 for installing photovoltaic panels A. The clamping assembly 30 is provided in two sets. The clamping assembly 30 includes a water platform 31 disposed on the outer wall of the precast column 20, the water platform 31 includes a support platform 311, an abutment rod 32 slidably installed with the support platform 311, a clamping plate 33 disposed on the outer wall of the abutment rod 32, and a first elastic member 34 disposed between the clamping plate 33 and the support platform 311.

[0023] The concrete piles 10 are entirely buried underground, and the precast columns 20 are inserted into the concrete piles 10, arranged vertically. Multiple precast columns 20 are installed along a predetermined path, with two sets of photovoltaic panels A positioned vertically between any two adjacent precast columns 20. Simultaneously, clamping components 30 are fixedly installed on the outer wall of the precast columns 20, their installation positions corresponding to the photovoltaic panels A, used for installing and fixing the photovoltaic panels A. Each set of clamping components 30 corresponds to the installation position of one photovoltaic panel A, and two sets of clamping components 30 are installed on the outer wall of each precast column 20, corresponding to the adjacent photovoltaic panels A on both sides. The precast columns 20 and concrete piles 10 are connected by an insertion method, with the lower end of the precast column 20 inserted into the concrete pile. The cement pile 10 is inserted into the cement pile to achieve a fixed connection between the two; the clamping component 30 is fixedly connected to the precast column 20, and the water platform 31 of the clamping component 30 is directly fixed to the outer wall of the precast column 20; a support platform 311 is fixed on the upper surface of the water platform 31, and the abutting rod 32 is fixedly connected to the support platform 311. The abutting rod 32 can slide back and forth along the length direction of the support platform 311; the clamping plate 33 is sleeved on the outer wall of the abutting rod 32 near the photovoltaic panel A; one end of the first elastic member 34 is fixedly connected to the outer wall of the clamping plate 33, and the other end is fixedly connected to the outer wall of the support platform 311. The first elastic member 34 is sleeved on the outer surface of the abutting rod 32, and the first elastic member 34 is a compression spring.

[0024] When installing photovoltaic panel A, the abutment rod 32 is pushed away from photovoltaic panel A. The abutment rod 32 slides along the support platform 311 away from photovoltaic panel A, simultaneously pushing the clamping plate 33 on its outer wall to move synchronously. When the clamping plate 33 moves, it generates a compressive force on the first elastic member 34 between itself and the support platform 311, causing the first elastic member 34 to deform. At this time, a gap is formed between the clamping plate 33 and the outer wall of the precast column 20, allowing photovoltaic panel A to be inserted. After the end of photovoltaic panel A is inserted into this gap, the abutment rod 32 is released, the first elastic member 34 loses the compressive force and returns to its original shape, generating a reverse elastic force. Push the clamping plate 33 towards the photovoltaic panel A. The clamping plate 33 drives the abutment rod 32 to slide along the support platform 311 towards the photovoltaic panel A until the clamping plate 33 is in close contact with the outer wall of the photovoltaic panel A, thus completing the clamping and fixing of the photovoltaic panel A. When it is necessary to remove the photovoltaic panel A, pull the abutment rod 32 away from the photovoltaic panel A again, repeating the above process of stretching the first elastic member 34, so that the clamping plate 33 is separated from the photovoltaic panel A, and the photovoltaic panel A can be taken out. After taking it out, release the abutment rod 32, and the abutment rod 32 and the clamping plate 33 will return to their initial positions under the elastic force of the first elastic member 34.

[0025] Example 2: Refer to Figures 1-8 This is the second embodiment of the present invention, which differs from the previous embodiment.

[0026] Specifically, the support platform 311 includes a first chamber 3111 for sliding of the abutment rod 32 and a second chamber 3112 communicating with the first chamber 3111, and multiple second chambers 3112 are arranged in an array.

[0027] The total cross-section of the multiple second chambers 3112 is smaller than the cross-section of the first chamber 3111.

[0028] The support platform 311 includes a first chamber 3111 for sliding the contact rod 32. A piston block is provided at one end of the contact rod 32 that slides inside the first chamber 3111, forming a sealed structure inside the first chamber 3111. At the same time, the inner wall of the first chamber 3111 extends outward to form a second chamber 3112. In this design, the second chamber 3112 is connected to the outside. Also, the total cross-section of all the second chambers 3112 is smaller than the cross-section of the first chamber 3111. The advantage of this design is that when the clamping plate 33 closes and clamps, the airflow through the second chamber 3112 is smaller, which makes the contact rod 32 slide more slowly and prevents it from directly hitting the surface of the photovoltaic panel A, reducing damage to the surface of the photovoltaic panel A. At the same time, it also provides safety for the operator.

[0029] Preferably, the second chamber 3112 is provided with a second elastic element 36 and a piston 37. The piston 37 and the bottom of the second chamber 3112 form a buffer chamber 31121, which is connected to the outside through a through hole 3113.

[0030] In this design, one end of the second elastic member 36 is fixedly connected to the inner wall of the second chamber 3112, and the other end of the second elastic member 36 is fixedly connected to the outer wall of the piston 37. Meanwhile, a buffer chamber 31121 is formed between the bottom of the second chamber 3112 and the piston 37. The buffer chamber 31121 is connected to the outside through a through hole 3113. The cross-section of the through hole 3113 is smaller than the cross-section of the buffer chamber 311121, which further restricts the gas flow and forms a double-layer buffer.

[0031] Preferably, one end of the abutment rod 32 extends through the clamping plate 33, and the upper end of the clamping plate 33 is provided with an inclined plate 331.

[0032] In this design, one end of the abutment rod 32 extends through the clamping block 33, meaning one end of the abutment rod 32 protrudes from the clamping plate 33. Simultaneously, the upper end of the clamping plate 33 extends outwards to form an inclined plate 331. The advantage of this design is that the entire photovoltaic panel A is lifted by a crane. Then, a traction rope is pulled at the lower end of the photovoltaic panel A, and the angle is adjusted by the operator, allowing the photovoltaic panel A to slide along the surface of the inclined plate 331. Using the gravity of the photovoltaic panel A, it slides downwards, pushing the clamping plate 33 away. Meanwhile, the advantage of setting a second elastic element 36 inside the buffer chamber 31121 is that when the clamping blocks 33 are pushed away from each other, the gas inside the first chamber 3111 compresses the second elastic element 36. The second elastic element 36 is a compression spring, which increases its resistance, preventing the clamping blocks 33 from sliding too quickly. At the same time, it provides a lifting effect for the photovoltaic panel A.

[0033] Furthermore, the end of the abutment rod 32 near the clamping plate 33 is chamfered to form a first oblique arc surface 321.

[0034] It should be noted that the mounting frame on the outer wall of photovoltaic panel A has a horizontal groove corresponding to the position of the abutment rod 32. During installation, when photovoltaic panel A falls, it slides along the surface of the inclined plate 331 and then falls between the two clamping plates 33. Subsequently, the two clamping plates 33 are pushed outward, which simultaneously causes the abutment rod 32 to slide, so that photovoltaic panel A will not shift during installation. Then, when photovoltaic panel A contacts the first inclined arc surface 321 of the outer wall of abutment rod 32, abutment rod 32 is pushed outward, and then abutment rod 32 enters the horizontal groove of photovoltaic panel A. At the same time, with the help of two layers of damping structure, the clamping plate 33 is prevented from directly impacting photovoltaic panel A.

[0035] Example 3: Reference Figures 1-8 This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0036] Specifically, the distance between the two water platforms 31 is greater than the installation thickness of the photovoltaic panel A.

[0037] Among them, a gap is provided between the two water platforms 31, and the distance of the gap is greater than the thickness of the photovoltaic panel A. At the same time, four sets of clamping components 30 are arranged in an array along the height direction on the outer wall of the prefabricated column 20, with two sets arranged horizontally. This allows the photovoltaic panel A to pass through the upper clamping components 30 and reach the bottom.

[0038] Preferably, a baffle 38 is detachably provided between the two water platforms 31.

[0039] Among them, the clamping components 30 are arranged along the height direction of the precast column 20, and the baffle 38 is installed between the second and fourth sets of clamping components 30 for bottom support of the bottom of the photovoltaic panel A.

[0040] Preferably, the outer wall of the baffle 38 is provided with a first slider 381, and the outer wall of the water platform 31 is provided with a first groove 312 for the first slider 381 to slide.

[0041] The baffles 38 of the two sets of horizontal clamping components 30 are provided with first sliding grooves 312 near their surfaces. At the same time, first sliders 381 are fixedly installed on the outer wall of the baffles 38. During installation, the baffles 38 are inserted between the lowest set of clamping components 30 along the height direction of the precast column 20, and then the first photovoltaic panel A is installed. After the first photovoltaic panel A is in place, the baffles 38 are inserted between the second set of clamping components 30 along the height direction of the precast column 20, and then the second photovoltaic panel A is installed.

[0042] The overall solution also has additional advantages. After installation, if disassembly is required, photovoltaic panel A can be lifted directly, and the contact rod 32 can be pushed open to achieve disassembly. At the same time, during use, it can withstand certain harsh environments, such as bird strikes and strong winds. When subjected to external forces, photovoltaic panel A is not fixedly connected, which can create a certain amount of space. It will squeeze one side of the clamping plate 33, and then the other clamping plate 33 will be pushed by the first elastic element 34 to fit against photovoltaic panel A. This ensures the clamping of photovoltaic panel A without allowing all the force to be applied directly to photovoltaic panel A, which would result in the force not being buffered and could potentially damage the photovoltaic panel.

[0043] During installation, the cement pile 10 is first buried underground, and then the lower end of the precast column 20 is inserted into the cement pile 10 to achieve a fixed connection. Multiple precast columns 20 are set along a preset path. Two sets of horizontal clamping components 30 are fixedly installed on the outer wall of each precast column 20. The water platform 31 of the clamping component 30 is fixed to the outer wall of the precast column 20. The upper surface of the water platform 31 is fixed with a support platform 311. The abutment rod 32 is slidably connected to the support platform 311. The clamping plate 33 is sleeved on the end of the abutment rod 32 near the photovoltaic panel A. The first elastic element 34 is sleeved on the outer surface of the abutment rod 32 and its two ends are respectively connected to the clamping plate 33 and the support platform 311. The support platform 311 has a first chamber 3111 and multiple array-connected second chambers 311. 2. A piston block is provided at one end of the abutment rod 32 to seal the first chamber 3111. The second chamber 3112 is provided with a second elastic element 36 and a piston 37. The piston 37 and the bottom of the second chamber 3112 form a buffer chamber 31121. The buffer chamber 31121 communicates with the outside through a through hole 3113. An inclined plate 331 is provided at the upper end of the clamping plate 33. A first inclined arc surface 321 is provided at the end of the abutment rod 32 near the clamping plate 33. Four sets of clamping components 30 are arranged along the height direction on the outer wall of the precast column 20. First, a baffle 38 is inserted between the horizontal platform 31 of the two lowest sets of clamping components 30, so that the first slider 381 of the baffle 38 slides into the first groove 312 of the horizontal platform 31 and is fixed. Then, the photovoltaic panel A is lifted by a crane. The lower traction rope is adjusted to allow photovoltaic panel A to slide down the inclined plate 331 under its own weight, pushing the clamping plate 33 and the contact rod 32 to slide. The first elastic element 34 is compressed and deformed, and the gas in the first chamber 3111 is slowly discharged through the second chamber 3112 and the through hole 3113. This, together with the second elastic element 36, forms a double-layer slowing effect. Photovoltaic panel A slides down to contact the first inclined arc surface 321, pushing the contact rod 32 to engage in the horizontal groove of the photovoltaic panel A mounting frame. After release, the first elastic element 34 and the second elastic element 36 return to their original positions, and the clamping plate 33 tightly contacts the photovoltaic panel A to complete the fixation. Then, a baffle 38 is inserted between the second set of clamping components 30, and the operation is repeated to install the second photovoltaic panel A. The beneficial effect is that... The cross-sectional design of the first chamber 3111 and the second chamber 3112, the buffer chamber 31121 and the through hole 3113, together with the second elastic element 36, form a double-layer buffer to prevent the clamping plate 33 from impacting the photovoltaic panel A and reduce damage. The inclined plate 331 of the clamping plate 33 and the first inclined arc surface 321 of the abutment rod 32 cooperate with the gravity of the photovoltaic panel A to facilitate quick positioning and installation, reduce the difficulty of operation. The baffle 38 enhances the support stability of the photovoltaic panel A. The detachable design facilitates disassembly and assembly. The double elastic element and sealing structure ensure a firm clamping. At the same time, the photovoltaic panel A can generate a certain amount of movement space to buffer external impact force and resist harsh environments such as bird strikes and strong winds, improve the stability and practicality of the device, and facilitate disassembly and assembly, reducing labor intensity.
