[0038] Embodiment 1

[0039] Reference Figure 1 and Figure 2 As shown, this embodiment provides a photovoltaic support column installation device 1, which is used to flip a column 100 and connect it to a ground pile 2. The column installation device 1 includes a connecting seat 11 detachably connected to the ground pile and a column flipping mechanism provided on the connecting seat, and the column flipping mechanism includes a fixed bracket 12, a column flipping bracket 13 hinged to the fixed bracket 12 and used to fix the column 100, and a driving component 14 provided on the fixed bracket 12 and the column flipping bracket 13, and the driving component 14 drives the column flipping bracket 13 to flip.

[0040] like Figure 3 and Figure 4 As shown, during the construction of the photovoltaic system, when installing the photovoltaic support column, the column installation device of the utility model is used. First, the connection seat is connected to the ground pile, and then the column is fixed on the column flip bracket. The driving component is operated by the handle crank to push the column flip bracket to flip. After the column is flipped and erected, the column is erected on the ground pile for fixing. The flipping process only requires at least one worker, which saves labor and solves the problem of low efficiency of column flipping and erecting. In addition, since there is no need to use large equipment such as cranes, it can save costs while improving efficiency.

[0041] As an embodiment, the driving assembly 14 includes a driven gear 142 fixed to the column flip bracket and a driving gear 141 rotatably supported on the fixed bracket, the driving gear 141 is meshed with the driven gear 142, and the driven gear 142 is driven to rotate by the driving gear 141. Gear transmission is not easy to slip. Furthermore, in order to save more effort when operating the driving assembly, the driving gear and the driven gear are both cylindrical gears, and the diameter of the driving gear is smaller than that of the driven gear. In order to facilitate manual operation, the driving gear 141 is arranged on the gear shaft, and the gear shaft is connected to a handle crank 143. The driving gear and the driven gear are meshed to form a reduction gear set, so that the small gear drives the large gear, which is more labor-saving. In addition, with the assistance of the handle crank, the column flip bracket can be driven to flip the column with less effort.

[0042] It is understandable that a motor may be used to drive a reduction gear set, and the photovoltaic support column may be flipped and erected electrically. Of course, the reduction gear set may also be replaced by other conventional transmission mechanisms, such as a chain transmission mechanism.

[0043] Specifically, the fixed bracket 12 includes two vertical plates 121, the gear shaft is rotatably supported on the two vertical plates, and the driving gear is arranged between the two vertical plates. Two ear plates 132 are arranged side by side on the column flip bracket 13, and the driven gear is arranged between the two ear plates, and the two ear plates are hingedly installed between the two vertical plates. The two ear plates and the two vertical plates can only be flipped up and down, but the horizontal freedom is limited. The positions of the fixed bracket and the column flip bracket are relatively fixed, so as to avoid misalignment of the driving gear and the driven gear, and ensure a smooth driving process.

[0044] Furthermore, a handle support frame 122 is provided on the side of one of the vertical plates, and the handle support frame 122 is provided with a support sleeve, and the rotating shaft of the handle crank is rotatably supported by the support sleeve and connected to the gear shaft. The handle support frame can stably support the handle crank to ensure that the handle crank can be shaken normally, thereby driving the driving gear to rotate.

[0045] In order to achieve the rapid fixation and separation of the column flip bracket and the column, a common clamp structure is provided on the column flip bracket, wherein the column flip bracket 13 is provided with a fixing plate 131 and a clamp bolt 133 connected to the fixing plate. The clamp bolt 133 is U-shaped, and more than two clamp bolts can be used at the same time to ensure that the column is reliably fixed. The fixing plate 131 is a steel plate, which is welded and fixed with two ear plates 132. The steel structure is welded and fixed as a whole, which can not only ensure the structural strength and extend the service life, but also is simple to process and has low manufacturing cost. The column is fixed to the column flip bracket by the clamp bolt and the fixing plate. The column can be fixed by tightening the clamp bolt. The column flip bracket can be separated from the column by loosening the clamp bolt, and the entire column installation device can be removed from the pile. After the clamp bolt fixes the column, it prevents the column from loosening and detaching from the column flip bracket during the flipping process, causing safety problems. The clamp bolt is adjustable in tightness and is suitable for columns of different specifications.

[0046] Referring to the existing ground pile structure, such as a steel spiral pile, the ground pile 2 is provided with a flange 21, and the flange 21 is provided with a connection portion connected to the column, that is, the middle area of ​​the flange surface, which is usually welded to the column, and of course, it can also be fixed by bolts, rivets, etc. The steel spiral pile has excellent strength performance, is economical and durable, and ensures that the column has a solid foundation. The ground pile adopts a common structure with a flange to facilitate fixing with the connecting seat of the installation device. The flange can be round or rectangular.

[0047] In order to connect the bottom of the column to the connection part on the flange after the column is turned over, the connection seat 11 is provided with a relief notch 111 corresponding to the connection part on the flange to avoid the column. The role of the relief notch is to avoid the connection seat from blocking the column. After the column is turned over and erected, the bottom of the column is connected to the connection part through the relief notch 111, and then the column can be welded or fixed in other ways.

[0048] A detachable connection structure is provided between the connection seat and the flange. In this embodiment, the connection seat 11 and the flange 21 are connected by bolts, and the bolts are distributed around the avoidance gap. In order to facilitate the removal of the entire column installation device from the flange, the avoidance gap 111 has a front opening, and the upper side of the front opening is connected to a sealing plate (not shown in the figure) by bolts. After the column is erected and welded, all bolts and sealing plates are removed first, and then the connection seat is moved horizontally to separate the entire column installation device from the flange.

[0049] Embodiment 2

[0050] like Figure 5 As shown, compared with the first embodiment, in order to achieve rapid connection and separation with the ground pile, the connecting seat 11 is provided with a slot 112 plugged into the flange 21. Specifically, the avoidance notch 111 has a front opening, and the slot 112 is connected on both sides and the rear side of the front opening of the avoidance notch to form a U-shaped structure. When the connecting seat is plugged into the flange, after the front opening of the avoidance notch corresponds to the position of the flange, the connecting seat can be pushed to plug the slot into the flange, and through the corresponding design of the slot and the flange, after the connecting seat is plugged into the flange of the ground pile, the avoidance notch and the connection part of the flange correspond. The avoidance notch does not interfere with the column during the disassembly process of the device, and can be directly pulled out along the avoidance notch, so that the connecting seat and the ground pile can be quickly connected and separated.

[0051] Furthermore, pin holes are provided on both sides of the front opening of the avoidance notch 111, and limit pins 113 are connected to limit the separation of the flange and the slot. When installing the column, the connecting seat is plugged into the flange of the ground pile, and the limit pin is inserted after the plugging is completed to fix the connecting seat and the entire column installation device to prevent the column from shifting or slipping during the column flipping process. After the column is installed, the limit pin is first pulled out, and then the connecting seat is moved away from the front opening of the avoidance notch to separate the connecting seat from the flange of the ground pile. The insertion and separation of the limit pin are very convenient, and there is no need to fasten with bolts as in Example 1, which facilitates operation.

[0052] The above is only a specific implementation of the utility model, but the protection scope 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 contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
