Description

Technical Field

[0001] This application relates to the field of installation foundation technology, and in particular to a prefabricated foundation structure for installing energy storage equipment. Background Technology

[0002] During the installation of energy storage equipment, a specialized foundation structure is essential for stable support, ensuring the safety and reliability of the equipment during operation. Currently, the foundation construction method for energy storage equipment in power distribution areas is typically on-site cast-in-place concrete. While this type of foundation structure can support the equipment, it has significant limitations in practical applications.

[0003] On-site pouring is not only inefficient, but also susceptible to variations in construction environment and operator skill, making it difficult to guarantee the quality of the foundation structure. Furthermore, it generates significant noise and dust, negatively impacting the surrounding construction site and environment. In addition, this method has a long construction period, requiring at least 13 days from foundation construction to final installation. During this time, maintenance is also vulnerable to vandalism; unauthorized entry by residents or vehicles can easily extend the construction period, further increasing the project's uncertainty.

[0029] During the installation of energy storage equipment, a specialized foundation structure is essential for stable support, ensuring the safety and reliability of the equipment during operation. Currently, the foundation construction method for energy storage equipment in power distribution areas is typically on-site cast-in-place concrete. While this type of foundation structure can support the equipment, it has significant limitations in practical applications.

[0030] On-site pouring is not only inefficient, but also susceptible to variations in construction environment and operator skill, making it difficult to guarantee the quality of the foundation structure. Furthermore, it generates significant noise and dust, negatively impacting the surrounding construction site and environment. In addition, this method has a long construction period, requiring at least 13 days from foundation construction to final installation. During this time, maintenance is also vulnerable to vandalism; unauthorized entry by residents or vehicles can easily extend the construction period, further increasing the project's uncertainty.

[0031] Based on this, this application provides a prefabricated foundation structure for installing energy storage equipment to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0032] Reference Figure 1 This application provides a prefabricated foundation structure for installing energy storage equipment, including: a pad 100 and a foundation base 200. The foundation base 200 is disposed on the pad 100. The top of the foundation base 200 is also provided with a reinforcing structure for placing the energy storage equipment. The foundation base 200 is provided with a cable routing chamber, and the foundation base 200 is provided with a cable through hole 210 on at least one side. The top of the foundation base 200 is provided with a cable inlet hole 220. Both the cable through hole 210 and the cable inlet hole 220 are connected to the cable routing chamber, so that the energy storage equipment can be connected to the target equipment by a cable passing through the cable inlet hole 220, the cable routing chamber and the cable through hole 210 in sequence.

[0033] This prefabricated foundation structure adopts a prefabricated design, achieving stable support for the energy storage equipment through the setting of a pad layer 100 and a foundation seat 200 with a reinforced structure. At the same time, the cable routing chamber in the foundation seat 200, together with the cable penetration hole 210 and the cable inlet hole 220, forms a dedicated cable channel. It can not only provide reliable load-bearing for the energy storage equipment, but also standardize cable routing. By using the prefabrication method, on-site pouring work is reduced, thereby improving construction efficiency, ensuring product quality, reducing construction noise and dust pollution, shortening the construction period, reducing the risk of human damage during project maintenance, and solving the problems of cumbersome cable layout and easy damage in traditional foundations, ensuring the safe and stable operation of the energy storage equipment.

[0034] Continue to refer to Figure 1It is understandable that the base 200 has a clearance groove 230 on its top, a cable hole 210 at the bottom of the clearance groove 230, and a reinforcing structure on the top of the base 200, located beside the clearance groove 230. The clearance groove 230 on the top of the base 200, located below the energy storage device, provides dedicated space for cable wiring to the energy storage device, avoiding inconvenience caused by narrow space at the bottom of the energy storage device. After the cable passes through the inlet hole 220 into the wiring chamber, it can smoothly connect to the energy storage device within the clearance groove 230, simplifying the wiring process and providing reasonable storage for the cable connection. Simultaneously, the clearance groove 230, in conjunction with the side reinforcing structure, fully utilizes the space below the energy storage device through a compact layout, reducing cable exposure while ensuring the load-bearing strength of the top of the base 200. This further protects the cable in conjunction with the wiring chamber, improving wiring stability and safety.

[0035] Understandably, the inlet hole 220 contains an MPP (Modified Polypropylene Pipe) tube 240, the inner diameter of which matches the outer diameter of the cable connected to the energy storage device. This tight fit reduces the gap between the two, significantly enhancing the sealing performance of the inlet hole 220. This structure effectively prevents external moisture, dust, and other impurities from entering the cable routing chamber through the inlet hole 220, avoiding damage to the insulation performance and lifespan of the cable inside the chamber due to contamination or moisture. This ensures the stability of the cable connection between the energy storage device and the target device, reducing the risk of failure caused by external environmental factors.

[0036] Reference Figure 1 It is understood that the reinforcing structure includes several channel steels 250, which are positioned on top of the foundation 200 and beside the clearance groove 230. The channel steels 250 themselves have good structural strength and load-bearing capacity, which can effectively enhance the support stability of the top of the foundation 200 for the energy storage device, ensuring that the energy storage device is placed stably.

[0037] Reference Figure 1 and Figure 3 Understandably, several mounting screws 251 are welded to the upper surface of the channel steel 250. These mounting screws 251 are used to connect with the energy storage equipment. The welding method ensures a secure connection between the mounting screws 251 and the channel steel 250, preventing loosening and ensuring the energy storage equipment is stably fixed to the base 200, reducing the risk of displacement during equipment operation or external interference. Simultaneously, the pre-set mounting screws 251 ensure precise alignment with the mounting holes of the energy storage equipment, avoiding adjustment difficulties caused by positional deviations during installation, further guaranteeing the convenience and reliability of installation.

[0038] Reference Figure 1It is understandable that the clearance groove 230 is equipped with several lifting rings 260. Before the energy storage equipment is installed on the prefabricated foundation structure, the lifting rings 260 can be used to easily connect with the external hoisting device, thereby stably lifting and transporting the entire prefabricated foundation structure to the designated location on the construction site, effectively improving the handling efficiency of the prefabricated foundation structure in the early stage of installation.

[0039] It is understandable that the subbase 100 and the foundation base 200 are cast as a single piece. This single-piece casting reduces the number of construction steps, simplifies the prefabrication process, and improves production efficiency. In addition, it enhances the connection strength and structural integrity of the two, thereby improving the load-bearing stability of the entire prefabricated foundation structure.

[0040] Reference Figure 2 It is understandable that the pad 100 has an opening 110, which communicates with the wiring chamber. While ensuring that the supporting function of the pad 100 for the foundation 200 is not significantly affected, structural weight reduction is achieved by reducing the amount of material used in the pad 100, thereby reducing the self-weight of the entire precast foundation structure. This reduces the load requirements on transportation vehicles and hoisting equipment, saves materials during production, and lowers production costs.

[0041] Reference Figure 1 It is understandable that the four side walls of the foundation 200 are equipped with cable entry holes 210. During actual installation or use, the direction of cable entry may be affected by various factors such as the layout of surrounding equipment, site space limitations, and the routing of underground pipelines. The cable entry holes 210 on the four side walls provide multiple options for cable routing. Construction personnel can choose the most convenient, shortest path, or least disruptive direction to route cables according to the actual site conditions, without being forced to detour to accommodate a single direction, thus reducing unnecessary cable loss and construction difficulty. At the same time, it also provides more possibilities for future equipment maintenance, line modification, or the addition of new cables.

[0042] Reference Figure 1 and Figure 2It is understandable that each side wall of the base 200 is provided with at least two cable-passing holes 210. During construction or use, the cable-passing holes 210 may be accidentally blocked due to concrete residue, dust accumulation, cable fragments, or other reasons. If each side wall has only one cable-passing hole 210, blockage will directly prevent the wiring in that direction from being properly installed. With at least two cable-passing holes 210, when one hole is accidentally blocked, the other hole can take over its function, ensuring that the wiring in that side wall direction is unobstructed without the need for additional adjustments to the wiring scheme or remedial construction. In addition, when there are multiple electronic devices that require power in the same direction, multiple cable-passing holes 210 can also ensure that the cables of each device can be installed independently and arranged separately, avoiding problems such as tangling, crushing and wear when all cables pass through a single hole, or heat dissipation obstruction and signal interference caused by cable stacking.

[0043] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
