Description

Technical Field

[0001] This utility model relates to the field of prefabricated steel platforms, specifically a prefabricated mountain photovoltaic transformer substation foundation steel platform. Background Technology

[0002] Prefabricated modular steel platforms for mountain photovoltaic transformer substations are modular steel structure foundations designed for complex mountainous terrain. They utilize high-strength steel and anti-corrosion treatment, and adapt to slope, wind and snow loads, and geological conditions through separate or integrated structural systems. This enables rapid assembly and standardized production, shortening the construction period and reducing costs compared to traditional cast-in-place concrete foundations. They also offer advantages such as environmental friendliness, durability, and high precision, meeting green construction requirements and becoming the preferred solution for mountain photovoltaic power station construction.

[0003] Currently, in the construction of existing prefabricated assembled mountain photovoltaic transformer substation foundation steel platforms, bolts are used to connect the various components of the steel platform. However, in actual operation, due to the large weight of the steel platform components and the complex terrain of mountainous areas, it is often difficult to use other lifting equipment for assembly. Therefore, in some cases, manual splicing of the steel platform components is required before bolting, which leads to certain inconveniences and safety risks during the assembly of the steel platform. Therefore, a prefabricated assembled mountain photovoltaic transformer substation foundation steel platform is proposed to address the above problems. Utility Model Content

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a prefabricated, assembled steel platform for the foundation of a mountain photovoltaic transformer substation. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A prefabricated, assembled mountain photovoltaic transformer substation foundation steel platform includes several base columns 1, several main beams 2, several longitudinal beams 3, several transverse beams 4, several top plates 5, and several connecting pieces 6. The two ends of the main beams 2 are respectively inserted into the interior of the base columns 1. Both ends of the main beams 2 are fixedly connected with L-shaped blocks 21. Several L-shaped blocks 21 are used in conjunction. Support blocks 22 and locking blocks 24 are fixedly installed on both sides of the main beams 2. A locking groove 23 is opened on one side of the support block 22. The locking block 24 is used in conjunction with the locking groove 23. Several longitudinal beams 3 and several transverse beams 4 are used in conjunction with several main beams 2. The bottom of several top plates 5 is respectively provided with a first connecting component 51 and a second connecting component 52. The first connecting component 51 is used in conjunction with the base columns 1, the second connecting component 52 is used in conjunction with the main beams 2, and several connecting pieces 6 are used in conjunction with several top plates 5. When assembling the main frame of the steel platform, several base columns 1 are installed in the required positions. Then, the two ends of several main beams 2 are respectively inserted into the interior of any two adjacent base columns 1. When the two ends of the main beams 2 are inserted into the interior of the base columns 1, four L-shaped blocks 21 can be interlocked with each other. The position of the main beams 2 is stabilized by the support block 22, the slot 23 and the locking block 24. Thus, any four main beams 2 can be stabilized inside the base columns 1. Then, the longitudinal beams 3 and the transverse beams 4 are respectively connected to the main beams 2. The first connecting component 51 and the second connecting component 52 are used to connect several top plates 5 to the base columns 1 and the main beams 2 respectively, so that the two ends of the main beams 2 are sealed inside the base columns 1 by the top plates 5. The connecting piece 6 is used to connect several top plates 5, thus completing the assembly of the steel platform.

[0018] Reference Figure 3 and Figure 4 The surface of the main beam 2 is provided with connecting grooves 31, and several connecting grooves 31 are used in conjunction with the longitudinal beams 3 and the transverse beams 4 respectively. By opening connecting grooves 31 on the surface of the main beam 2, the longitudinal beams 3 or transverse beams 4 can be inserted into the interior of the connecting grooves 31 so that the longitudinal beams 3 and transverse beams 4 are flush with the main beam 2, so as to avoid affecting the laying of the top plate 5.

[0019] Reference Figure 3 and Figure 4 The bottom of both the longitudinal beam 3 and the transverse beam 4 are fixedly connected with a first screw 32. One end of the first screw 32 passes through the main beam 2 and is slidably connected to the inner cavity of the main beam 2. A first nut 33 is threaded onto one end of the first screw 32 and abuts against the bottom of the main beam 2. When connecting the longitudinal beam 3 and the transverse beam 4 to the main beam 2, one end of the first screw 32 passes through the main beam 2, and then the first nut 33 is connected to the first screw 32, so that the longitudinal beam 3 and the transverse beam 4 can be stabilized on the top of the main beam 2.

[0020] Reference Figure 3 and Figure 4Grooves 34 are provided on opposite sides of the longitudinal beam 3 and the transverse beam 4, and the two grooves 34 are used together. By providing grooves 34 on opposite sides of the longitudinal beam 3 and the transverse beam 4 and connecting the two grooves 34, the longitudinal beam 3 and the transverse beam 4 are kept in a flush position, so as to avoid affecting the laying of the top plate 5.

[0021] Reference Figure 2 and Figure 3 The first connecting component 51 includes several connecting frames 5101, which are fixedly installed at the bottom of several top plates 5. The connecting frames 5101 are slidably sleeved on the surface of the base column 1. A first bolt 5102 is rotatably connected to the surface of the connecting frame 5101. One end of the first bolt 5102 passes through the connecting frame 5101 and is threadedly connected to the base column 1. After the longitudinal beam 3 and the transverse beam 4 are installed, the top plate 5 is attached to the top of the base column 1, and the connecting frame 5101 is sleeved on the surface of the base column 1. Then, one end of the first bolt 5102 passes through the connecting frame 5101 and is threadedly connected to the base column 1, thereby fixing the position of the top plate 5. At the same time, the two ends of the main beam 2 are sealed inside the base column 1 by the top plate 5.

[0022] Reference Figure 2 and Figure 3 The second connecting assembly 52 includes several brackets 5201, which are fixedly installed on the bottom of several top plates 5. The brackets 5201 are slidably sleeved on the surface of the main beam 2. A support rod 5202 is slidably sleeved inside the bracket 5201. The top of the support rod 5202 abuts against the bottom of the main beam 2. A second bolt 5203 is rotatably connected to the bottom of the bracket 5201. One end of the second bolt 5203 passes through the bracket 5201 and is threadedly connected to the support rod 5202. By attaching the top plate 5 to the surface of the main beam 2 and the crossbeam 4, and sleeved the bracket 5201 on the surface of the main beam 2, then inserting the support rod 5202 into the inside of the bracket 5201, and fixing the position of the support rod 5202 with the second bolt 5203, the top plate 5 can be fixed to the surface of the main beam 2 and the crossbeam 4.

[0023] Reference Figure 2 and Figure 3 Several connecting pieces 6 are respectively attached to the surface of several top plates 5. Several second screws 61 are fixedly connected to the bottom of the connecting pieces 6. Several second screws 61 pass through several top plates 5. A second nut 62 is threaded on one end of the second screw 61 and abuts against the bottom of the top plate 5. When the top plate 5 is laid on the top of the base column 1, main beam 2, longitudinal beam 3 and transverse beam 4, the connecting pieces 6 are attached to the surface of the adjacent top plate 5 and one end of the second screw 61 passes through the top plate 5. Then the second nut 62 is connected to the second screw 61 to splice several top plates 5 together.

[0024] Working Principle: During the assembly of the main frame of the steel platform, several base columns 1 are installed in the required positions. Then, the two ends of several main beams 2 are respectively inserted into the interior of any two adjacent base columns 1. When the two ends of the main beams 2 are inserted into the interior of the base columns 1, four L-shaped blocks 21 can be interlocked. The position of the main beams 2 is stabilized by the support block 22, the slot 23, and the locking block 24, thus stabilizing any four main beams 2 inside the base columns 1. Then, the longitudinal beams 3 and transverse beams 4 are respectively connected to the main beams 2, so that the longitudinal beams 3 and transverse beams 4 are respectively inserted into the interior of the connecting slot 31, so that the longitudinal beams 3 and transverse beams 4 are kept in a flush position with the main beams 2. One end of the first screw 32 passes through the main beam 2. Then, the first nut 33 is connected to the first screw 32 to effectively stabilize the position of the longitudinal beams 3 and transverse beams 4, and at the same time, the groove 34 keeps the longitudinal beams 3 and transverse beams 4 in a stable position. Hold the top plate 5 in a level position, then attach a portion of the top plate 5 to the top of the base column 1, and fit the connecting bracket 5101 onto the surface of the base column 1. Insert one end of the first bolt 5102 through the connecting bracket 5101 and thread it onto the base column 1. This will fix the position of the top plate 5 and seal both ends of the main beam 2 into the base column 1. Then, lay another portion of the top plate 5 on the surface of the main beam 2 and the crossbeam 4, and fit the bracket 5201 onto the main beam 2. Insert the support rod 5202 into the inside of the bracket 5201 and fix it with the second bolt 5203. Then, lay the remaining top plate 5 on the top of the longitudinal beam 3 and the crossbeam 4, attach the connecting piece 6 to the surface of the adjacent top plate 5, and let one end of the second screw 61 pass through the top plate 5. Then, connect the second nut 62 to the second screw 61 to splice several top plates 5 together, thereby completing the assembly of the steel platform.
