Description

Technical Field

[0001] This application relates to the field of prefabricated substation technology, and particularly to a base for a prefabricated substation. Background Technology

[0002] A prefabricated substation is a complete substation unit that integrates high-voltage electrical equipment, low-voltage electrical equipment, and auxiliary facilities within a closed metal enclosure. It is widely used in urban and rural power distribution systems. Its base structure typically supports the weight of the entire substation and remains in contact with the ground. During installation and transportation, it requires lifting equipment for overall hoisting.

[0003] However, existing prefabricated substation base structures generally lack effective waterproofing designs, especially at the installation points of the lifting components. To meet lifting requirements, these components are movably connected to the base and penetrate into the substation's interior. Since structural gaps often exist at the connection between the lifting components and the base, rainwater or surface water can easily seep into the substation through the gap between the lifting components and the outer shell, eventually accumulating in the base plate area. Long-term moisture accumulation not only leads to corrosion and rust on the base plate but can also cause safety hazards such as short circuits and decreased insulation performance, severely impacting the substation's service life and operational stability. Utility Model Content

[0004] The purpose of this application is to provide a base for a prefabricated substation, which aims to solve the technical problem in the prior art where water enters the interior of the prefabricated substation through the installation gap of the lifting components.

[0005] To achieve the above objectives, this application proposes a base for a prefabricated substation, the base of which includes: The frame includes a support frame and a reinforcing beam connected to the support frame. The reinforcing beam and the support frame enclose a receiving structure.

The lifting component has a mounting hole in the support frame, which communicates with the receiving structure. The lifting component passes through the mounting hole into the receiving structure, and the lifting component is clearance-fitted with the mounting hole. A waterproof device is provided, which is sealed to the frame and seals the connection port to prevent water from entering the interior of the prefabricated substation through the connection port.

[0006] In one embodiment, the number of lifting components is at least two, and the at least two lifting components are distributed at intervals along the support frame. The number of waterproof devices corresponds one-to-one with the number of lifting components.

[0014] In one embodiment, the base further includes a support plate, which is fixedly connected to the support frame and is used to support the transformer heat sink.

[0015] The above-mentioned technical solution of this application has at least the following beneficial technical effects: The technical solution of this application uses a waterproof device to seal the connection with the frame.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this application. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0019] The embodiments described in this application are only some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments described herein without inventive effort are within the scope of protection of this application. In the description of this application, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] A prefabricated substation is a complete substation unit that integrates high-voltage electrical equipment, low-voltage electrical equipment, and auxiliary facilities within a closed metal enclosure. It is widely used in urban and rural power distribution systems. Its base structure typically supports the weight of the entire substation and remains in contact with the ground. During installation and transportation, it requires lifting equipment for overall hoisting.

[0021] However, existing prefabricated substation base structures generally lack effective waterproofing designs, especially at the installation points of the lifting components. To meet lifting requirements, these components are movably connected to the base and penetrate into the substation's interior. Since structural gaps often exist at the connection between the lifting components and the base, rainwater or surface water can easily seep into the substation through the gap between the lifting components and the outer shell, eventually accumulating in the base plate area. Long-term moisture accumulation not only leads to corrosion and rust on the base plate but can also cause safety hazards such as short circuits and decreased insulation performance, severely impacting the substation's service life and operational stability.

[0022] To address the aforementioned technical problems, this application proposes a base for a prefabricated substation. Please refer to [link / reference needed]. Figures 1 to 4 In one embodiment of this application, the base of the prefabricated substation includes a frame 1, a lifting component 2, and a waterproofing device 3. The frame 1 includes a support frame 11 and a reinforcing beam 12 connected to the support frame 11. The reinforcing beam 12 and the support frame 11 enclose a receiving structure 13. The receiving structure 13 and the frame 1 have a communication opening, which communicates with the interior of the prefabricated substation. The support frame 11 has an installation hole that communicates with the receiving structure 13. The lifting component 2 passes through the installation hole into the receiving structure 13. The lifting component 2 is fitted with the installation hole with a clearance, so that the lifting component 2 can move along the axis of the installation hole or rotate around the axis of the installation hole. This facilitates the adjustment of the sling angle, buffers the impact of force, and thus achieves stable force distribution and convenient operation during hoisting, protecting the prefabricated substation structure from damage. However, because there is a gap between the lifting component 2 and the installation hole, rainwater or ground water can enter the interior of the prefabricated substation through this gap. Therefore, the waterproof device 3 is sealed to the frame 1, and the waterproof device 3 seals the connection port to prevent water from entering the interior of the box-type substation through the connection port.

[0023] The technical solution of this application adopts a sealed connection between the waterproof device 3 and the frame 1. The waterproof device 3 can seal the connection port and prevent water from entering the interior of the box-type substation through the connection port, thereby helping to slow down the corrosion process of the box-type substation base plate and thus improving the protection level and long-term operational stability of the box-type substation.

[0024] Please see Figures 1 to 6In one embodiment, the number of lifting components 2 is at least two, and these at least two lifting components 2 are distributed at intervals along the support frame 11. The number of waterproof devices 3 corresponds one-to-one with the number of lifting components 2. Specifically, the number of lifting components 2 is six, and any two of the six lifting components 2 form a group, forming three groups in total. The three groups of lifting components 2 are distributed at intervals along the base, with two lifting components 2 in each group symmetrically distributed on both sides of the base. This embodiment can achieve a uniform force distribution on the lifting components 2, which is beneficial to improving the stability and anti-tilting ability of the base, ensuring the smooth operation of the substation under different working environments. At the same time, setting the number of lifting components 2 to six provides a more flexible and stable lifting scheme, ensuring safety and efficiency during operation.

[0025] Please see Figure 3 In one embodiment, the waterproof device 3 includes a first side plate 31, a second side plate 32, and a top plate 33 that are sealed to each other. One end of the first side plate 31 is sealed to the support frame 11, and the other end is sealed to the reinforcing beam 12. One end of the second side plate 32 is sealed to the support frame 11, and the other end is sealed to the reinforcing beam 12. The first side plate 31 and the second side plate 32 are spaced apart on both sides of the axis of the lifting member 2. The top plate 33 is sealed to the first side plate 31, the second side plate 32, the support frame 11, and the reinforcing beam 12. The top plate 33 is located on the side of the lifting member 2 facing the interior of the prefabricated substation. The first side plate 31, the second side plate 32, and the top plate 33 can seal the communication opening. Through this sealed connection, the first side plate 31, the second side plate 32, and the top plate 33 together form a complete waterproof closed space, effectively preventing external water sources or moisture from seeping into the interior of the prefabricated substation, greatly improving the waterproof effect and reducing the risk of equipment getting damp and corroded. Furthermore, the sealed connection between the side plates and the top plate 33 not only effectively isolates the water source but also enhances the overall stability of the structure. The sealed connection of the reinforcing beam 12 helps to disperse the external pressure, ensuring the strength and durability of the overall device. In addition, by distributing the first side plate 31 and the second side plate 32 at intervals on both sides of the lifting component 2, it can be ensured that each sealing point maintains excellent sealing performance under different working environments, avoiding the risk of leakage or failure during long-term use. At the same time, the sealed connection of the top plate 33 to the four edges ensures all-round protection for the prefabricated substation. This solution, by separating the various components of the waterproof device 3 and sealing them together, allows for convenient replacement or repair of individual components without affecting the stability and sealing effect of the entire structure.

[0026] In one embodiment, the sealing connection method is welding. This embodiment, through welding, provides a more robust and durable seal, effectively preventing the infiltration of water and external contaminants, and improving the waterproof performance and stability of the equipment. Welded seals have high strength and durability, ensuring excellent sealing performance during long-term use, reducing the risk of equipment damage and failure due to seal failure, and contributing to improved overall equipment reliability and service life.

[0027] In one embodiment, the sealing connection method is a press-fit seal. This embodiment, through the press-fit seal connection, achieves a fast and reliable sealing effect, effectively preventing water and external substances from penetrating and enhancing waterproof performance. The press-fit seal provides strong mechanical fixing force, ensuring a stable sealing state during long-term equipment operation, reducing malfunctions caused by seal loosening or failure, and contributing to improved equipment reliability and durability. Furthermore, the press-fit seal facilitates subsequent maintenance and disassembly, improving operational convenience.

[0028] In one embodiment, the sealing connection method is adhesive sealing. This embodiment, through adhesive sealing, provides a flexible and efficient sealing effect, effectively preventing water and external contaminants from penetrating and enhancing waterproof performance. Adhesive sealing has strong adhesion and adaptability, maintaining a stable sealing state in complex environments, reducing the risk of equipment failure due to poor sealing, and contributing to improved equipment reliability and service life. This method also has good process adaptability, facilitating large-scale production and rapid installation, optimizing production efficiency and cost control.

[0029] Please see Figure 4 In one embodiment, the lifting component 2 includes a lifting part 21, a first limiting part 22, and a second limiting part 23. One end of the lifting part 21 passes through a mounting hole into the receiving structure 13 and is fixedly connected to the first limiting part 22. The lifting part 21 and the mounting hole are in clearance fit. The first limiting part 22 can prevent the lifting part 21 from sliding out of the receiving structure 13. The other end of the lifting part 21 is fixedly connected to the second limiting part 23, which can prevent the lifting part 21 from sliding into the receiving structure 13. This embodiment, through the cooperation of the lifting part 21 and the first and second limiting parts 23, can effectively prevent the lifting part 21 from sliding out of or into the receiving structure 13, improving the stability and safety of the equipment during transportation and use. It is beneficial to ensure the firmness and reliability of the lifting component 2, reducing the risk of equipment failure and damage caused by improper installation or external forces, and improving the overall safety and service life of the equipment.

[0030] Please see Figure 6In one embodiment, the support frame 11 includes a frame body 111 and a reinforcing plate 112. The reinforcing plate 112 is fixedly connected to the frame body 111 and has mounting holes in it, into which the lifting component 2 is movably installed. This embodiment, by providing the reinforcing plate 112, enhances the supporting force of the lifting component 2, ensuring its stability and reliability during lifting. This reduces the risk of deformation or loosening due to uneven stress, thus improving the safety and stability of the equipment. It also optimizes the flexibility and reliability of lifting operations, ensuring efficient use of the equipment in various working environments.

[0031] Please see Figure 6 In one embodiment, the reinforcing plate 112 includes a first plate 1121 and a second plate 1122, which are fixedly connected to the frame body 111. Both the first plate 1121 and the second plate 1122 have mounting holes, and are spaced apart along the axial direction of the mounting holes. This embodiment effectively disperses the load borne by the support frame 11 during use by using the first plate 1121 and the second plate 1122, enhancing the stability and strength of the overall structure. The fixed connection of the first plate 1121 and the second plate 1122 to the frame body 111, and their spaced distribution along the axial direction of the mounting holes, optimizes the force distribution and transmission path, reduces local stress concentration, and helps improve the deformation resistance and load-bearing capacity of the support frame 11.

[0032] Please see Figure 1 , Figure 3 and Figure 5 In one embodiment, the base further includes a support plate 4, which is fixedly connected to the support frame 11. The support plate 4 is used to support the transformer heat sink. This embodiment, through the provision of the support plate 4, can effectively support the transformer heat sink, ensuring its stability during operation. This improves the transformer's heat dissipation effect, prevents overheating, enhances the transformer's working efficiency and service life, and strengthens the overall structural stability and safety of the equipment.

[0033] This application aims to protect the base of a prefabricated substation. The technical solution of this application uses a waterproof device 3 to seal the connection with the frame 1. The waterproof device 3 can seal the connection port and prevent water from entering the interior of the prefabricated substation through the connection port, thereby helping to slow down the corrosion process of the base plate of the prefabricated substation and thus improving the protection level and long-term operational stability of the prefabricated substation.
