[0031] Embodiment one

[0032] The embodiment of the utility model discloses a kind of modular support structure of photovoltaic support foundation, refer to Figures 1 to 3 , including side plate 1 and top plate 2, the number of side plate 1 is provided with several, enclose annular structure, form the area to be constructed 3 in annular structure middle, the area to be constructed 3 is used to fill concrete to form cement pile, cement pile is used to deposit and fixed photovoltaic panel support.Top plate 2 is fixed on side plate 1, top plate 2 is fixed with U bolt 21, the bending part of U bolt 21 is inserted into the area to be constructed 3, after concrete is filled into the area to be constructed 3, U bolt 21 bending part is embedded in concrete, the threaded portion of U bolt 21 is located outside the area to be constructed 3, i.e. the threaded portion of U bolt 21 is exposed outside concrete pile.Each side plate 1 has first fixed structure 4 between, top plate 2 and side plate 1 have first limiting structure 5 between, so the whole support structure is connected into shape, prevent concrete molding process each mold plate piece connection collapse, cause molding failure.The side plate 1 and top plate 2 of the scheme are customized specific size, as long as installing and fixing in construction site, it can form the mold of prefabricated concrete, convenient and fast.In addition, the side plate 1 and top plate 2 of the scheme are all prefabricated pieces of metal material, such as steel plate prefabricated piece, service life is long, can be reused, and cost is low.

[0033] Side plate 1 is long strip steel plate, preferred example, the annular structure surrounded by each side plate 1 is rectangle. Side plate 1 size can be pre-cut customized according to need, such as the length of side plate 1 in the length direction of annular structure is slightly long, and in the width direction, the length of side plate 1 is slightly short. In one example, the length of side plate 1 in length direction is 1000mm, and the width is 250mm;The length of side plate 1 in width direction is 250mm, and the width is 250mm.When the length needed in length direction is too long, it can be spliced by 2 pieces or more side plate 1, and adjacent side plate 1 is fixedly connected by first fixed structure 4.

[0034] Refer to Figure 2The first fixing structure 4 comprises a fixing pin 41 and a plug-in seat 42 arranged on the side plate 1. The fixing pin 41 is in a U-shaped structure, and the plug-in seat 42 is a hollow metal seat with a plug hole 421 arranged therein. The plug-in seat 42 is welded to the outer wall of the side plate 1 away from the construction area 3 and located at the edge of the side plate 1 in the length direction. The number of plug-in seats 42 is preferably two, and the two plug-in seats 42 are respectively located at the two ends of the side plate 1 in the length direction. When the adjacent side plates 1 are spliced, the two legs of the fixing pin 41 can be inserted into the plug holes 421 of the adjacent side plates 1, so as to limit the displacement of the side plates 1 in the length direction. Since the support structure composed of the side plate 1 and the top plate 2 in the present scheme is used to fill the concrete, the plates do not need to be absolutely sealed. As long as the side plates 1 are not cracked and dislocated during the vibration and solidification of the concrete, the effect is good. In addition, the fixing pin 41 in the present scheme can also be in other shapes, and it is not necessarily in a U-shaped structure, as long as it is an integral structure comprising two legs that can be inserted into the adjacent side plate 1.

[0035] When the side plate 1 in the length direction is spliced with the side plate 1 in the width direction, the end of the side plate 1 in the length direction can be placed against the side wall of the side plate 1 in the width direction. At this time, the plug-in seats 42 in the side plates 1 in different directions are close to each other, and the fixing pin 41 can be inserted from top to bottom.

[0036] Referring to Figure 3 The first limiting structure 5 comprises a fixing bolt 51 and a clamping groove 54 arranged on the upper surface of the side plate 1. The clamping groove 54 is in a strip shape and extends from one end of the top of the side plate 1 to the other end. A plurality of pairs of fixing holes 53 are arranged on the two sides of the top plate 2. The fixing bolt 51 passes through the fixing hole 53 and is clamped with the clamping groove 54 to fix the top plate 2 and the side plate 1. In order to increase the fastening of the connection, two fixing bolts 51 can be arranged side by side. In order to adapt to the annular structure with different width requirements, a plurality of pairs of fixing holes 53 are arranged along the length direction of the top plate 2. A plurality of top plates 2 can be arranged in the length direction of the annular structure according to the needs.

[0037] The fixing bolt 51 is adopted in the present embodiment because the bolt is easy to obtain and low in cost. The same effect can also be achieved by using rivets or pins of the same size.

[0038] The number of U-shaped bolts 21 is two, and the two U-shaped bolts 21 are arranged side by side on the top plate 2. The U-shaped bolt 21 is fixed to the top plate 2 by a bolt and extends into the construction area 3. That is, after the concrete is filled into the construction area 3, the U-shaped bolt 21 is embedded in the concrete, and the connecting part of the U-shaped bolt 21 is exposed from the concrete and used to install and fix the bracket of the photovoltaic panel.

[0039] The working principle of the present scheme is that the prefabricated side plates 1 and top plates 2 made of metal material can be directly moved to the construction site for use, the side plates 1 are used to form the required annular structure, the adjacent side plates 1 are connected by the fixing pins 41 and fixed, and the reinforcement cage is placed inside. The top plate 2 at the top is inserted on the side plate 1 through the fixing bolt 51, so that the U-shaped bolt 21 can be fixed in the air on the area to be constructed 3, and then the concrete is filled into the area to be constructed 3, vibrated and waited to be solidified, and then the side plates 1 and the top plate 2 are removed, which is convenient, fast, green and environmentally friendly.

[0040] Embodiment two

[0041] The difference between embodiment two and embodiment one is that the first limiting structure 5 is different. Specifically, referring to Figure 4 The first limiting structure 5 includes a clamping groove 54 arranged at the top of the side plate 1 and a protrusion 55 arranged at the bottom of the top plate 2. The clamping groove 54 is arranged along the length direction of the side plate 1, and the protrusion 55 on the top plate 2 is buckled in the clamping groove 54, so that the top plate 2 and the side plate 1 can be fixed. In order to adapt to the side plates 1 with different distances, the number of protrusions 55 can be set to several, and the several protrusions 55 are arranged in linear intervals. Moreover, the top plate 2 can be buckled at any point in the length direction of the side plate 1, and compared with the bolt connection and fixing mode of embodiment one, the bolt disassembly time is saved, which is convenient and fast.

[0042] The protrusions 55 can also be connected with the top plate 2 in a detachable design, and the distance between the protrusions 55 can be adjusted to adapt to the needs of different widths of the area to be constructed 3.

[0043] Obviously, the above embodiments are only examples for clear illustration, and not a limitation on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present disclosure.
