Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to a prefabricated box-type transformer platform. Background Technology

[0002] Precast box-type transformer platforms (referred to as precast box-type transformer platforms) are commonly used infrastructure in the power transmission field. They are mainly composed of pipe piles, precast beams, and a precast platform. The precast beams are welded to the top of the pipe piles, and the precast platform is a precast reinforced concrete component erected on top of the precast beams to support the transformer equipment.

[0003] Due to the large size and weight of prefabricated platforms, existing technologies typically divide them into several sub-platforms for easy transportation. To achieve the splicing and fixing of the sub-platforms, existing solutions pre-embed multiple spaced steel plates on the end face of each sub-platform. During installation, the corresponding steel plates on the end faces of adjacent sub-platforms are welded together to connect the sub-platforms and form a complete prefabricated platform.

[0004] However, the welding connection method using multiple spaced steel plates has obvious drawbacks: on the one hand, the spaced steel plates disperse the welding nodes, resulting in poor integration between the sub-platforms and affecting the overall structural stability of the prefabricated platform; on the other hand, the corresponding steel plates of adjacent sub-platforms are prone to large seams due to the spaced arrangement.

[0024] Please refer to the following: Figures 1 to 4 The prefabricated transformer substation platform provided by this utility model will now be described. The prefabricated transformer substation platform includes a plurality of pipe piles 10, prefabricated beams 20 and prefabricated platforms 30. The plurality of pipe piles 10 are arranged at intervals; the prefabricated beams 20 are erected on top of the pipe piles 10 and fixedly connected to the pipe piles 10; the prefabricated platforms 30 are erected on top of the prefabricated beams 20 and fixedly connected to the prefabricated beams 20, and are composed of a plurality of separately arranged sub-platforms 31 spliced ​​together. The splicing end face of each sub-platform 31 is fully covered with a first steel plate 32, and two adjacent sub-platforms 31 are welded and fixed together by the first steel plate 32.

[0025] Specifically, steel plates are pre-embedded at the bottom of the precast beam 20 corresponding to the pipe pile positions, and are welded to the pipe piles through the steel plates. Similarly, the top is welded to the precast platform 30 through the steel plates.

[0026] It should be noted that in this embodiment, "fully covered by the first steel plate 32" means that the first steel plate 32 continuously covers the entire splicing end face of the sub-platform 31, and there are no gaps formed by the intermediate arrangement in the prior art. The outline of the first steel plate 32 is adapted to the outline of the splicing end face of the sub-platform 31, ensuring that the splicing end faces of adjacent sub-platforms 31 can be connected through the complete steel plate contact surface during welding.

[0027] The beneficial effects of the prefabricated transformer substation platform provided by this utility model are as follows: Compared with the prior art, the prefabricated transformer substation platform provided by this utility model replaces the existing multiple steel plates that are spaced apart by fully covering the splicing end face of the sub-platform 31 with a first steel plate 32, so that the welding nodes form a continuous whole, which greatly improves the connection and integration between the sub-platforms 31 and effectively enhances the overall structural stability of the prefabricated platform 30; at the same time, the continuously covered first steel plate 32 can closely fit the splicing end face of the adjacent sub-platforms 31, significantly reducing or even eliminating the splicing seam, solving the defect of large splicing seams in the prior art.

[0028] In one specific embodiment of the prefabricated transformer substation platform provided in this utility model, the back of the first steel plate 32 is provided with a plurality of pre-embedded steel bars, which are vertically fixedly connected to the first steel plate 32 and are used to be pre-embedded in the sub-platform 31.

[0029] It should be noted that in this embodiment, the pre-embedded reinforcing bars are evenly distributed along the back of the first steel plate 32. One end of the pre-embedded reinforcing bars is fixed to the first steel plate 32 by welding or other means, and the other end is embedded in the reinforced concrete during the prefabrication of the sub-platform 31. The pre-embedded reinforcing bars and the stressed reinforcing bars inside the sub-platform 31 can be connected by binding or welding to ensure reliable anchorage of the pre-embedded reinforcing bars and the sub-platform 31.

[0030] In this embodiment, the embedded steel bars can firmly connect the first steel plate 32 and the sub-platform 31 into one unit, avoiding relative displacement or separation between the first steel plate 32 and the sub-platform 31 during the welding process, and significantly improving the connection strength between the first steel plate 32 and the sub-platform 31. At the same time, by transmitting the force through the embedded steel bars, the load at the splice of the sub-platform 31 can be evenly transmitted to the entire sub-platform 31 structure, further enhancing the overall load-bearing capacity and structural stability of the prefabricated platform 30.

[0031] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated transformer substation platform provided in this utility model, the top of the prefabricated beam 20 is provided with a plurality of first positioning structures, and the bottom of the sub-platform 31 is provided with a plurality of second positioning structures. The second positioning structures correspond one-to-one with the first positioning structures and cooperate to position the sub-platform 31 in the horizontal direction.

[0032] In this embodiment, the first positioning structure and the second positioning structure are matched by a limiting fit. Several first positioning structures are evenly distributed on the top of the precast beam 20, and the number of second positioning structures at the bottom of each sub-platform 31 matches the number of first positioning structures on the corresponding precast beam 20, so as to ensure that the sub-platform 31 can quickly find the installation position through the positioning structure when it is placed on the precast beam 20.

[0033] Beneficial effects: In this embodiment, the one-to-one correspondence between the first positioning structure and the second positioning structure enables the rapid installation and positioning of the sub-platform 31, preventing the sub-platform 31 from shifting during installation and ensuring precise alignment of the splicing end faces of adjacent sub-platforms 31, thus facilitating the welding of the first steel plate 32. At the same time, the positioning structure can limit the platform before and after welding, preventing welding deformation or displacement during use, further ensuring the integrity of the connection and the stability of the structure, and improving installation efficiency.

[0034] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated transformer substation platform provided in this utility model, the first positioning structure is a positioning groove 21, and the second positioning structure is a positioning platform.

[0035] It should be noted that in this embodiment, the groove size of the positioning groove 21 is adapted to the outer dimensions of the positioning platform, and the height of the positioning platform matches the depth of the positioning groove 21, ensuring that the positioning platform can be completely embedded in the positioning groove 21 to form bidirectional limiting in the up and down and left and right directions. In addition, the contact surface between the positioning groove 21 and the positioning platform is a flat and smooth surface to reduce frictional resistance during the fit.

[0036] In this embodiment, the positioning groove 21 and the positioning platform are used in a cooperative structure, which has higher positioning accuracy and more reliable limiting effect. It can effectively limit the horizontal displacement and vertical sway of the sub-platform 31. Compared with other positioning forms, this structure is easy to process and has a stable fit. It can ensure that the splicing end faces of adjacent sub-platforms 31 always remain in a tight fit, providing a stable foundation for the welding process, further reducing the seam and improving the overall structural stability.

[0037] like Figure 1 and Figure 2 As shown, in a specific embodiment of the prefabricated transformer substation platform provided in this utility model, the upper edge of the positioning groove 21 is chamfered.

[0038] It should be noted that in this embodiment, the chamfer of the upper edge of the positioning groove 21 is a rounded corner or a beveled corner. The chamfer covers the entire upper opening edge of the positioning groove 21. The size of the chamfer is designed to facilitate the smooth insertion of the positioning platform. It will not affect the positioning accuracy due to an excessively large chamfer, nor will it fail to play a guiding role due to an excessively small chamfer.

[0039] In this embodiment, the chamfered edge of the upper edge of the positioning groove 21 serves as an installation guide, effectively preventing the positioning platform from colliding or getting stuck with the edge of the positioning groove 21. This allows the positioning platform to be quickly and smoothly embedded into the positioning groove 21, reducing the difficulty of installation and improving installation efficiency. At the same time, the chamfered structure reduces stress concentration at the edge of the positioning groove 21, preventing damage to the edge of the positioning groove 21 during installation, ensuring the integrity and service life of the positioning structure, and ensuring long-term reliable positioning performance.

[0040] like Figure 1 and Figure 3 As shown, in a specific embodiment of the prefabricated transformer substation platform provided in this utility model, the top of the prefabricated platform 30 is provided with a water-blocking platform 33 and a drain outlet 35, and the drain outlet 35 is located in the area enclosed by the water-blocking platform 33.

[0041] It should be noted that in this embodiment, the water-blocking platform 33 is set along the edge and inside of the top of the prefabricated platform 30 to form a closed enclosure area. Its height is based on the ability to prevent rainwater, dew and other liquids from overflowing the platform. The number of drainage outlets 35 can be set one or more according to the area size of the prefabricated platform 30, and the position of the drainage outlets 35 is selected at the lowest point of the enclosure area to ensure that the liquid can be smoothly collected and discharged.

[0042] In this embodiment, the water-blocking platform 33 can effectively prevent liquid from overflowing from the top of the platform to the surrounding areas, avoiding the liquid from flowing to the precast beam 20, pipe pile 10 or electrical equipment on the ground and causing corrosion or short circuit; the drain port 35 will drain the liquid in the enclosed area in time, preventing the liquid from accumulating on the top of the platform, thereby protecting the transformer equipment from water immersion, extending the service life of the equipment and the precast platform 30, and improving the safety and reliability of the precast transformer platform.

[0043] like Figure 3 and Figure 4 As shown, in a specific embodiment of the prefabricated transformer substation platform provided in this utility model, a steel strip 34 is pre-embedded on the top of the water-retaining platform 33.

[0044] It should be noted that in this embodiment, the steel strip 34 is made of low-carbon steel with good weldability. When pre-embedded, its upper surface protrudes 1-5mm from the top of the retaining wall 33 to facilitate welding. The length of the steel strip 34 can cover the entire length of the retaining wall 33, and the width of the steel strip 34 is designed to be 80-120mm to ensure sufficient welding space and connection area. Simultaneously, the bottom of the steel strip 34 is equipped with pre-embedded reinforcing bars, which are used to fix it to the retaining wall 33, preventing the steel strip 34 from detaching from the concrete during subsequent welding and ensuring the stability of the welded joint.

[0045] In this embodiment, the core function of the steel strip 34 embedded in the top of the water-retaining platform 33 is to provide a reliable welding substrate for other structural components of the box-type transformer. This solves the problem that traditional concrete platforms cannot be directly welded to metal structural components, eliminating the need for additional drilling of holes on the platform to install anchor bolts or welding of embedded plates, simplifying the installation process of structural components and reducing construction difficulty. At the same time, the low-carbon steel strip 34 has excellent weldability, enabling it to form high-strength and stable welded joints with structural components, avoiding the defects of easy loosening of bolted connections, and improving the connection reliability between structural components and the prefabricated platform 30. In addition, the steel strip 34 can also enhance the impact resistance and wear resistance of the top of the water-retaining platform 33, prevent damage to the concrete at the top of the platform during welding, and balance the convenience of installation with the structural integrity of the platform, further improving the overall practicality of the prefabricated box-type transformer platform.

[0046] like Figure 4 As shown, in a specific embodiment of the prefabricated transformer substation platform provided in this utility model, a drain pipe 36 is pre-embedded inside the drain outlet 35.

[0047] It should be noted that in this embodiment, the drain pipe 36 is made of corrosion-resistant and high-strength pipe (such as steel pipe, PVC pipe, etc.). The inner diameter of the drain pipe 36 is designed according to the drainage volume requirement. One end is pre-embedded in the concrete of the drain outlet 35 and is flush with the top surface of the platform. The other end extends out of the bottom of the platform and faces the preset drainage direction to ensure that the liquid can be discharged smoothly and without backflow.

[0048] In this embodiment, the pre-embedded drain pipe 36 inside the drain outlet 35 can prevent the concrete at the drain outlet 35 from being damaged by long-term liquid scouring and erosion, prevent the drain outlet 35 from being blocked or deformed, and ensure that the drainage channel is unobstructed for a long time. At the same time, the drain pipe 36 can guide the direction of liquid discharge, so that the liquid is accurately discharged to the designated position, and prevent the liquid from flowing randomly and causing corrosion to the surrounding structure, further improving the drainage reliability and service life of the precast platform 30.

[0049] In one specific embodiment of the prefabricated transformer substation platform provided in this utility model, the upper surface of the prefabricated platform 30 is inclined upwards in all directions from the drain outlet 35.

[0050] It should be noted that in this embodiment, the tilt angle of the surface of the prefabricated platform 30 is designed as a gentle slope of 1% to 3%, and the tilt direction is all pointing to the location of the drain outlet 35. The tilt transition of the entire platform surface is smooth, without obvious protrusions or depressions, ensuring that the liquid can flow naturally along the slope to the drain outlet 35 and will not form a dead corner for water accumulation.

[0051] In this embodiment, the design of the prefabricated platform 30 surface inclined towards the drain port 35 can utilize gravity to achieve automatic collection and discharge of liquid, completely solving the problem of water accumulation on the top of the platform and avoiding problems such as equipment corrosion and concrete aging caused by water accumulation. At the same time, the gentle slope design will not affect the placement stability of the transformer equipment. While ensuring the drainage effect, it also takes into account the load-bearing function of the platform, further improving the practicality and reliability of the prefabricated transformer platform.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
