Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology. Background Technology

[0002] Currently, most gravity-type concrete pier supports used in photovoltaic systems are not height-adjustable. Most height-adjustable supports achieve adjustment via tightening and loosening bolts. Refer to Chinese utility model patent CN 205754164 U, which discloses an adjustable-height photovoltaic support. Anchor steel bars are embedded in a concrete pile foundation. The bottom of a connecting steel pipe extends into the concrete pile foundation and connects to the anchor steel bars, while the other end of the connecting steel pipe protrudes from the concrete pile. The upper end of the connecting steel pipe has external threads, and the top of the connecting steel pipe has multiple spaced notches extending axially along the connecting steel pipe. A locking nut is provided at the upper end of the connecting steel pipe. The front and rear columns are circular steel pipes, with an outer diameter smaller than the inner diameter of the connecting steel pipe, allowing the circular steel pipe to be inserted into the connecting steel pipe. During installation, the columns are inserted into the inner cavity of the connecting steel pipe, and after the height adjustment meets the requirements, the locking nut is used to secure it. Later operation and maintenance can also adjust the column height by tightening and loosening the locking nut. However, this nut adjustment mechanism is time-consuming and labor-intensive. Utility Model Content

[0003] This invention provides a height-adjustable concrete pier photovoltaic support and photovoltaic power station, avoiding the time-consuming and laborious method of adjustment by tightening nuts in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] First, a height-adjustable concrete pier photovoltaic support is provided, comprising a concrete pier and a column. The concrete pier has an installation groove with an opening at the top and extending vertically. The bottom of the column is inserted into the installation groove. A height adjustment structure is provided between the bottom of the column and the installation groove. The height adjustment structure includes a plurality of adjustment grooves provided on the side wall of the column and spaced apart along the height direction, and a controlled support component installed on the side wall of the installation groove. The controlled support component includes a plate that can be controlled to rotate upward. After the column height is adjusted, the controlled support component is inserted into the adjustment groove to restrict the column from moving downward. When controlled, the controlled support component rotates upward and disengages from the adjustment groove.

[0006] Preferably, the controlled support component further includes a support shaft disposed on the inner side of the mounting groove sidewall, and the tray is rotatably connected to the support shaft.

[0007] Preferably, the mounting groove sidewall has a through groove, the tray includes a body and a lever connected to the rear end of the body, the lever passes through the through groove and is limited by the upper sidewall of the through groove to restrict the downward rotation of the tray head end, and the lever rotates to the lower side of the through groove when the tray head end rotates upward.

[0008] Preferably, the mounting groove sidewall is fixed with connecting seats on opposite sides of the through groove, and the two ends of the support shaft are connected to the connecting seats on both sides.

[0009] Preferably, the connecting seat is a T-shaped structure, including a fixed plate and a protruding plate vertically connected to the middle of the fixed plate. The fixed plate is fixed to the side wall of the mounting groove by expansion bolts, and the protruding plate is connected to the support shaft.

[0010] Preferably, the paddle has a rectangular structure and extends rearward from the middle of the rear end of the body.

[0011] Preferably, the bottom of the body is provided with a guide slope.

[0012] Preferably, the head end of the body is provided with a guide arc surface.

[0013] Preferably, the column is a square tube, the mounting groove is a rectangular groove, the four side walls of the square tube are provided with adjustment grooves, and the four groove walls of the mounting groove are connected to controlled support components.

[0014] Preferably, the mounting groove is filled with concrete after the column height is adjusted, so as to combine the concrete pier and the column into a whole.

[0015] In addition, a photovoltaic power station is also provided, including the aforementioned concrete pier photovoltaic support.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. The concrete pier has an installation groove with an open top and extending vertically. The bottom of the column is inserted into the installation groove, and a height adjustment structure is provided between the bottom of the column and the installation groove. Several adjustment grooves are spaced along the height direction on the side wall of the column. A controlled support component is installed on the side of the installation groove. When controlled, the support plate of the controlled support component can disengage from the adjustment groove, allowing the bottom of the column to move up and down along the installation groove to adjust the column height. After the column height is adjusted, the support plate is inserted into the adjustment groove to support the column, restricting its downward movement and maintaining it at the set height. Therefore, the support plate, in conjunction with the adjustment grooves at different heights, allows the bottom of the column to extend and retract within the installation groove, thus changing the column height. Height adjustment can be performed simply by rotating the support plate, avoiding the time-consuming and laborious method of adjusting with a locking nut in existing technologies.

[0018] Furthermore, the height of the column can be adjusted by changing the number and different positions (spacing) of the slots.

[0019] In addition, since the controlled support components are located inside the concrete pier, they do not affect the aesthetics.

[0020] 2. The mounting slot has a through groove on its side wall. The support plate includes a main body and a lever connected to the rear end of the main body, the lever passing through the through groove. After the column height is adjusted, the front end of the support plate is inserted into the adjustment groove, while the lever engages with the upper side wall of the through groove to limit the downward rotation of the support plate head. When the support plate head rotates upward, the lever rotates downward towards the through groove, and the main body head protrudes forward, allowing it to be inserted into the adjustment groove, limiting the downward displacement of the column. However, when the column is pulled upward, the support plate can rotate normally around its support axis, without limiting the column displacement. Height adjustment can be performed simply by moving the lever.

[0021] 3. To facilitate the disengagement of the tray from the adjustment slot, the bottom of the main body is provided with a guide ramp, and the head end of the main body is provided with a guide arc surface. Thus, when the column is pulled upwards, the tray can rotate normally around its support axis. At this time, the bottom wall of the adjustment slot interacts with the guide ramp, driving the tray to rotate upwards, eventually disengaging from the adjustment slot after passing through the guide arc surface. Then, pressing down on the lever maintains a gap between the head end of the main body and the side wall of the column, allowing the column to move upwards. After the height adjustment is complete, the upper side wall of the corresponding adjustment slot is higher than the head end of the tray. Releasing the lever causes the head end of the tray to rotate downwards under gravity and enter the adjustment slot. Releasing the column causes it to move slightly downwards, and the head end of the tray engages with the upper side wall of the adjustment slot, restricting the downward movement of the column, thus completing the adjustment.

[0022] 4. After the column height is adjusted, the mounting groove can be filled with concrete, thus combining the concrete pier and the column into a single unit. This increases the stability of the support and prevents the column from loosening.

[0023] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0036] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0037] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," and "rear," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] Reference Figures 1 to 9 As shown, this embodiment provides a height-adjustable concrete pier photovoltaic support structure, which serves as part of a photovoltaic power station and is on which photovoltaic modules 6 are installed. The photovoltaic support structure has several columns 3 for vertical support, with the bottom of each column 3 installed in a concrete pier 2. The concrete pier 2 has an installation groove 21 with an open top and extending vertically. The bottom of each column 3 is inserted into the installation groove 21, and a height adjustment structure is provided between the bottom of the column and the installation groove 21. While existing height adjustment structures have various implementations, the adjustment is relatively cumbersome. In this embodiment, the height adjustment structure includes several adjustment grooves 31 spaced apart along the height direction on the side wall of the column and a controlled support component 1 installed on the side wall 211 of the installation groove. The controlled support component 1 is inserted into the adjustment groove 31 after the column height is adjusted, restricting the downward movement of the column 3. The controlled support component 1 can disengage from the adjustment groove 31 when under control.

[0042] In some embodiments, the controlled support component 1 includes a support shaft 12 and a support plate 13 rotatably connected to the support shaft. Here, the support plate 13 can rotate upward, but its downward rotation is restricted. After the column height is adjusted, the support plate 13 is inserted into the adjustment slot. Because its downward rotation is restricted, it can provide support for the column. When the support plate 13 rotates upward, it disengages from the adjustment slot. After the support plate separates from the adjustment slot, the bottom of the column can move up and down within the mounting slot.

[0043] In the height adjustment structure described above, the side wall of the column has several adjustment slots spaced apart along the height direction. A controlled support component is installed on the side of the mounting slot. When controlled, the support plate of the controlled support component can detach from the adjustment slot, so that the bottom of the column can move up and down along the mounting slot to adjust the height of the column. After the column height is adjusted, the support plate is inserted into the adjustment slot to support the column, restrict the column from moving downward, and keep the column at the set height. Therefore, the support plate cooperates with the adjustment slots at different heights to realize the expansion and contraction of the bottom of the column in the mounting slot, and the height of the column changes accordingly.

[0044] It is understandable that the range of column height adjustment can be achieved by adjusting the number and different positions (spacing) of the slots.

[0045] In addition, since the controlled support components are located inside the concrete pier, they do not affect the aesthetics.

[0046] To achieve controlled operation of the controlled support components, such as Figure 3 and Figure 4 As shown, the mounting groove sidewall 211 has a through groove 22. The support plate 13 includes a main body and a lever 131 connected to the rear end of the main body, the lever 131 passing through the through groove 22. After the column height is adjusted, the front end of the support plate is inserted into the adjustment groove, while the lever engages with the upper sidewall of the through groove to limit the downward rotation of the support plate head. When the support plate head rotates upward, the lever 131 rotates downward towards the through groove, and the main body head protrudes forward, allowing it to be inserted into the adjustment groove to limit the downward displacement of the column. However, when the column is pulled upward, the support plate can rotate normally around its support axis, without limiting the column displacement. Height adjustment can be performed simply by moving the lever, avoiding the time-consuming and laborious method of adjustment by tightening a nut in the prior art.

[0047] like Figure 3 and Figure 4 As shown, the mounting groove sidewall 211 has connecting seats 11 fixed on opposite sides of the through groove 22, and the two ends of the support shaft 12 are connected to the connecting seats 11 on both sides. Specifically, the connecting seat 11 has a T-shaped structure, which includes a fixing plate 111 and a protruding plate 112 perpendicularly connected to the middle of the fixing plate. The fixing plate 111 is fixed to the mounting groove sidewall 211 with expansion bolts, and the protruding plate 112 is connected to the support shaft 12.

[0048] In some embodiments, the lever 131 has a rectangular structure, extending rearward from the upper middle position of the rear end of the body. The rear of the body has a through-hole 134 for connection with the support shaft 12. Thus, while the support plate is connected to the support shaft, the lever can pass through the through slot. It is understood that the through slot is high enough to provide sufficient movement space for the lever, allowing the front end of the support plate to detach from the adjustment slot. To facilitate the detachment of the front end of the support plate from the adjustment slot, the bottom of the body has a guide ramp 132. The head end of the body has a guide arc surface 133. Thus, when the column is pulled upward, the support plate can rotate normally around its support shaft. At this time, the bottom wall of the adjustment slot interacts with the guide ramp, driving the support plate to rotate upward, eventually disengaging from the adjustment slot after passing through the guide arc surface. At this point, the lever can be pressed downward to maintain a gap between the head end of the body and the side wall of the column, allowing the column to move upward. After the height is adjusted to the correct position, the upper side wall of the adjustment slot should be higher than the head of the pallet. Release the lever, and the head of the pallet will rotate downwards under gravity and enter the adjustment slot. At this point, release the column; the column will move slightly downwards, and the head of the pallet will engage with the upper side wall of the adjustment slot, restricting the column's downward movement, thus completing the adjustment. It is understood that the height of the adjustment slot is large enough to accommodate the head of the pallet moving in and out.

[0049] In some embodiments, the column 3 is a square tube, the mounting groove 21 is a rectangular groove, and each of the four side walls of the square tube is provided with an adjustment groove 31. Each of the four groove walls of the mounting groove is connected to a controlled support component 1. This fixes the column in four directions, making the support more stable and reliable.

[0050] Preferably, the column 3 is made of aluminum alloy or stainless steel square tubing. This not only provides corrosion resistance but also high strength and a long service life. Furthermore, it allows for large-scale industrial production, which helps reduce costs.

[0051] Understandably, the mounting groove is filled with concrete, specifically fine aggregate concrete, after the column height has been adjusted, to integrate the concrete pier and the column into a single unit. This increases the stability of the support and prevents the column from loosening.

[0052] Furthermore, other structures for photovoltaic mounting systems can refer to existing technologies. Figure 8 As shown in the example, the upper end of the column 3 is connected to the longitudinal beam 4 through the hinge 32, and the crossbeam 5 is vertically and crosswise fixed above the longitudinal beam by the fixing bolts 41. The photovoltaic module 6 is installed on the crossbeam through the pressure block assembly 51.

[0053] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
