Description
Technical Field
[0001] This utility model relates to the field of transformer substation technology, specifically to a fixed support for a photovoltaic transformer substation foundation. Background Technology
[0002] Setting up photovoltaic power generation projects on plateaus has significant advantages: 1. Plateau regions have excellent sunlight conditions and abundant sunshine; 2. Plateau regions have a relatively fragile natural environment and low vegetation coverage, which leads to low land utilization, making them suitable for photovoltaic power generation projects.
[0003] A prefabricated substation, also known as a box-type transformer, is an essential piece of equipment in photovoltaic power generation projects. Due to the uneven terrain of the plateau, when installing a prefabricated substation, it is necessary to first dig a pit and install multiple support columns. The substation platform is then installed on top of these support columns. Only after the level of the substation platform is installed can the substation be installed on it. The structure formed after the multiple support columns and the substation platform are installed is called the prefabricated substation foundation.
[0004] The overall installation process of the transformer substation foundation is as follows: multiple support columns are inserted into separate foundation pits, the support columns are fixed using cross steel pipes, and the foundation pit is poured. During the pouring process, a level is used to ensure that the tops of the multiple support columns are in a horizontal state as a whole. Finally, the transformer substation platform is erected on the support columns.
[0005] The current disadvantage of installing transformer substation foundations is that after measuring the levelness of the foundation, cross steel pipes are used to fix the support columns of the foundation. During the process of pouring concrete until the concrete solidifies, because the cross steel pipes are erected on uneven ground, slight subsidence of the ground can cause the levelness of the transformer substation foundation to shift. Since the cross steel pipes are a whole, they are not easy to adjust. After the above problems occur, the transformer substation foundation needs to be reinstalled. Utility Model Content
[0006] The purpose of this utility model is to provide a fixed support for the foundation of a photovoltaic transformer box, so as to solve the problem in the background art that the horizontal deviation cannot be corrected after the cross steel pipe is erected.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A fixed support for a photovoltaic transformer substation foundation includes a platform frame and support columns installed at the four corners of the bottom of the platform frame. The support columns have horizontal wing plates on their tops. The foundation includes a first support and a second support, installed on the front and rear sides of the platform frame, respectively. The first support includes a first horizontal bar and two vertical bars. The first horizontal bar is located at the bottom of the wing plate of the front support column to support the front support column. The two vertical bars are respectively installed at both ends of the first horizontal bar via clamps. It also includes an adjusting ring, the upper end of which is rotatably connected to the bottom of the vertical bar. A fixing rod is threaded to the bottom of the adjusting ring, and the bottom of the fixing rod abuts against the ground. The second support has the same structure as the first support, with the first horizontal bar in the second support located at the bottom of the wing plate of the rear support column to support the rear support column.
[0008] Furthermore, it also includes at least one second horizontal bar, the two ends of which are fixed to the first bracket and the second bracket respectively by clamps.
[0009] Furthermore, the wing plate at the top of the support column protrudes on both the front and rear sides. There are two first brackets, and the first horizontal bars of the two first brackets are respectively located at the bottom of the front and rear wing plates of the front support column. It also includes a short pipe, the two ends of which are connected to the two first brackets by clamps. There are two second brackets, and the first horizontal bars of the two second brackets are respectively located at the bottom of the front and rear wing plates of the rear support column. The two second brackets are connected by another short pipe through clamps.
[0010] Furthermore, a support plate is snapped onto the bottom of the fixing rod; there are multiple support plates, including horizontal support plates and support plates with different inclination angles, and one support plate is selected to snap onto the bottom of the fixing rod to abut against the ground.
[0011] A bolt is installed on the bottom side of the adjusting ring, with one end of the bolt facing the fixing rod. The fixing rod can be tightened or loosened by rotating the bolt.
[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention uses a first bracket and a second bracket to fix the transformer substation foundation. The first horizontal bar and two vertical bars in the first and second brackets provide support, ensuring the foundation remains level during concrete pouring. Each vertical bar in the first and second brackets has an adjusting ring at its bottom. By rotating the adjusting ring clockwise or counterclockwise, and with workers manually holding the fixing rod (to prevent rotation), the height of the adjusting ring can be adjusted via its threaded connection to the fixing rod. Therefore, if ground subsidence occurs during concrete pouring, the transformer substation foundation can be leveled back to the required standard. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.
[0018] like Figure 1 , Figure 2 As shown, a fixed support for a photovoltaic transformer substation foundation is provided. The substation foundation includes a platform frame 1 and support columns 2 installed at the four corners of the bottom of the platform frame 1. A horizontal wing plate 3 is provided on the top of the support column 2. The foundation includes a first support and a second support, which are respectively installed on the front and rear sides of the platform frame 1. The first support includes a first horizontal bar 4 and two vertical bars 5. The first horizontal bar 4 is located at the bottom of the wing plate 3 of the front support column 2 to support the front support column 2. The two vertical bars 5 are respectively installed at both ends of the first horizontal bar 4 by clamps 6. It also includes an adjusting ring 7, the upper end of which is rotatably connected to the bottom of the vertical bar 5. The adjusting ring 7 rotates circumferentially along the vertical bar 5 and does not slide relative to it in the vertical direction. A fixing rod 8 is threadedly connected to the bottom of the adjusting ring 7, and the bottom of the fixing rod 8 abuts against the ground. The structure of the second support is the same as that of the first support. The first horizontal bar 4 in the second support is located at the bottom of the wing plate 3 of the rear support column 2 to support the rear support column 2.
[0019] This utility model is applied to the pouring stage of the transformer substation foundation. The transformer substation foundation itself includes a platform frame 1 and support columns 2 at the four corners of the bottom of the platform frame 1. Usually, it is sufficient to have support columns 2 at the four corners. In practical applications, transformer substation foundations with six support columns 2 are often selected. Figure 1The bottom of support column 2 in the transformer substation foundation is omitted. In actual installation, the length of support column 2 is longer than the height of the first bracket. The bottom of support column 2 needs to be inserted into the hole in the ground. Since the depth of the hole excavation cannot be precisely determined, after excavating the hole to an approximate depth, the six support columns 2 are inserted into the corresponding holes. Then, the first bracket and the second bracket are set on the front and rear sides of the transformer substation foundation, respectively, to support the foundation. At this time, a level is used to check the levelness of the transformer substation foundation to ensure that the levelness of the foundation meets the standard in the initial state of the first and second brackets supporting the foundation. After the first and second brackets are erected, concrete is poured into the hole, and the installation of the transformer substation foundation is completed after the concrete sets.
[0020] The main technical problem this invention addresses is that after the first and second supports are erected, during the concrete curing process, due to poor geographical conditions at the installation site of the transformer substation foundation, such as uneven ground and insufficient soil bearing capacity, varying degrees of subsidence may occur during curing. Even slight subsidence can affect the levelness of the substation foundation after installation. Conventional supports cannot be readjusted after erection, necessitating reinstallation if the aforementioned problems occur during foundation installation. This invention addresses this issue by providing an adjusting ring 7 at the bottom of the vertical rod 5. By rotating the adjusting ring 7 forward or backward, and with the worker manually holding the fixing rod 8 to prevent rotation, the height of the adjusting ring 7 can be adjusted. This allows for the readjustment of the substation foundation to restore its levelness to the standard should on-site ground subsidence occur during pouring. The lower end of the adjusting ring 7 is threadedly connected to the fixed rod 8. During adjustment, the adjusting ring 7 can be raised or lowered by rotation. In the supported state, the threaded connection bears the pressure of the adjusting ring 7, and the adjusting ring 7 will not rotate due to gravity. This is because a thread is a helical mechanical structure that converts rotational motion into linear motion. When the threaded pair is subjected to axial load, the thread teeth squeeze against each other, forming friction to counteract the axial force and prevent loosening. Due to the large contact area between the threads and the fact that gravity can only compress the threads axially, there will be no relative movement even if the adjusted adjusting ring 7 is not fixed.
[0021] Furthermore, it also includes at least one second horizontal bar 10, with both ends of the second horizontal bar 10 fixed to the first bracket and the second bracket respectively by clamps 6. The second horizontal bar 10 is used to connect the first bracket located on the front side of the transformer substation foundation and the second bracket located on the rear side of the transformer substation foundation, reducing swaying and enhancing stability.
[0022] Furthermore, the wing plate 3 at the top of the support column 2 protrudes on both the front and rear sides. There are two first supports, with the first horizontal bars 4 of each first support located at the bottom of the front and rear wing plates 3 of the front support column 2, respectively. It also includes a short pipe 11, with both ends of the short pipe 11 connected to the two first supports via clamps 6. There are also two second supports, with the first horizontal bars 4 of each second support located at the bottom of the front and rear wing plates 3 of the rear support column 2, respectively. The two second supports are connected by another short pipe 11 via clamps 6. The pairing of first and second supports is also for more stable support of the transformer foundation. Wing plates 3 are provided on both the front and rear sides of the support column 2, and the two first supports support the front and rear wing plates 3 respectively. The two first supports clamp the support column 2, achieving a better fixing effect, preventing slippage even under external force.
[0023] Furthermore, a support plate 9 is snapped onto the bottom of the fixing rod 8; there are multiple support plates 9, including horizontal support plates 9 and support plates 9 at different inclination angles. One support plate 9 is selected and snapped onto the bottom of the fixing rod 8 to abut against the ground. The support plate 9 is designed to increase the contact area between the fixing rod 8 and the ground, preventing the fixing rod 8 from sliding. However, in uneven terrain, the fixing rod 8 is often erected on sloping ground. By setting multiple support plates 9 with different inclination angles, and selecting a support plate 9 with a suitable inclination angle according to the on-site installation conditions, a better anti-slip effect can be achieved.
[0024] like Figure 3 As shown, a bolt 71 is installed on the bottom side of the adjusting ring 7, with one end of the bolt 71 facing the fixing rod 8. By rotating the bolt 71, the fixing rod 8 can be tightened or loosened. The bolt 71 is locked after the adjusting ring 7 has been adjusted, preventing the adjusting ring 7 from being directly adjusted. Although the adjusting ring 7 will not rotate under gravity, it may still rotate under external force or misoperation. Therefore, the bolt 71 is provided to prevent the above situation from occurring.
