Description

Technical Field

[0001] This utility model relates to the field of photovoltaic facility technology, specifically to a prefabricated photovoltaic booster transformer base. Background Technology

[0002] Prefabricated photovoltaic step-up transformer modules are mainly used in the power transmission and distribution links of photovoltaic power generation projects. As a core piece of equipment for grid connection, they are characterized by rapid deployment and flexible mobility. They are suitable for power supply in remote areas, emergency backup power, and public facilities. They can realize functions such as remote management and data analysis, effectively improving the operating efficiency of photovoltaic power plants.

[0003] The existing photovoltaic step-up transformer prefabricated cabin base has problems such as poor foundation bearing capacity and instability due to the lack of supporting pile foundation after being pre-buried underground. In addition, the drainage effect below the base is poor after groundwater seeps out, which affects the support stability and service life of the base. Therefore, a photovoltaic step-up transformer prefabricated cabin base is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a photovoltaic boost transformer prefabricated cabin base, which provides a highly stable foundation for the photovoltaic boost transformer prefabricated cabin.

[0005] The technical solution adopted by this utility model to solve its technical problem is a photovoltaic step-up transformer prefabricated cabin base, including a cement prefabricated base, a pile assembly and a drainage assembly, wherein the pile assembly and the drainage assembly are both arranged at the bottom of the cement prefabricated base;

[0006] The foundation pile assembly includes a pile rod with a spiral cap fixed at the bottom. The bottom of the precast cement base has equally spaced insertion holes on both sides for inserting the pile rod. The top of the pile rod is a flange structure and is fixedly connected to the insertion holes by bolts.

[0007] By adopting the above technical solution, a highly stable foundation base is provided for the photovoltaic booster transformer prefabricated cabin through a mechanism composed of a cement prefabricated base, pile components, and drainage components.

[0008] Specifically, an annular base is formed on the outer periphery of the bottom of the pile hole, a concrete cover plate is provided on the top of the annular base, an annular sealing groove is formed on the top surface of the annular base, and a rubber sealing ring is provided in the annular sealing groove.

[0009] By adopting the above technical solution, and by setting the annular sealing groove and the rubber sealing ring, the sealing between the top of the pile insertion port and the inside of the precast cement base can be guaranteed.

[0010] Specifically, the drainage assembly includes a water guide groove formed on the bottom surface of the precast concrete base and water guide pipes inserted on both sides of the precast concrete base, with the bottom of the water guide pipes communicating with the water guide groove.

[0011] The water channel is designed in a grid pattern.

[0012] By adopting the above technical solution, the drainage components can provide a channel for the groundwater seeping from the bottom of the precast concrete foundation to flow, thus preventing water from accumulating in one place and affecting the bottom balance of the foundation.

[0013] Specifically, the water guide pipe is provided with threaded ribs for guiding water.

[0014] Specifically, a drain elbow is inserted at the top of the water pipe.

[0015] By adopting the above technical solution, the drainage assembly consisting of a water pipe, threaded ribs, and drainage elbows can help the groundwater seeping from the bottom of the base to be discharged to the ground through the water pipe, preventing water from accumulating under the base, thereby maintaining the stability of the base and extending its service life.

[0016] The beneficial effects of this utility model are as follows: The structure, composed of a precast concrete base, pile components, and drainage components, provides a highly stable foundation for the photovoltaic step-up transformer precast cabin. The structure utilizes piles with spiral caps fixed at the bottom, which engage with the insertion points within the precast concrete base. A flange frame and bolts are used for secure connection, effectively enhancing the connection strength between the base and the ground. Furthermore, a highly efficient drainage system is formed by a grid-like drainage channel and water pipes inserted on both sides, promptly draining accumulated water from the bottom of the base and preventing corrosion of the base and internal equipment. This improves the operational safety and reliability of the equipment. It solves the problems of existing photovoltaic step-up transformer precast cabin bases, which suffer from poor foundation bearing capacity and instability due to the lack of supporting piles after underground embedment, and the poor drainage effect below the base when groundwater seeps out, affecting the base's support stability and service life.

The bottom of the precast concrete base 1 is then embedded into the pit. Subsequently, a pile 3 is driven into the pit through the insertion port 2, and the flange above the pile 3 is bolted to the insertion port 2, thereby enhancing the connection strength between the base and the ground. A concrete cover plate 5 is then placed on the annular support 4 on the insertion port 2. The rubber sealing ring 42 ensures the airtightness between the insertion port 2 and the interior of the precast concrete base 1, thus enabling the photovoltaic step-up transformer to... The prefabricated pressure transformer cabin provides a stable base. During use, the drainage assembly consisting of water pipe 7, threaded ribs 71, and drainage elbows 72 helps to drain groundwater seeping from the bottom of the base to the ground, preventing water accumulation under the base, thus maintaining the stability of the base and extending its service life.
