Description

Technical Field

[0001] This application relates to the field of prefabricated substation technology, and in particular to a waterproof double-door prefabricated substation. Background Technology

[0002] With the widespread application of prefabricated substations in power systems, their waterproof performance has become a crucial factor in ensuring normal equipment operation. Traditional double-door designs typically use two doors connected to the frame by hinges, with the door's closure depending on the door panels' engagement. However, due to the double-door design, a gap is often created when the two doors are closed, which can become a pathway for water to enter the prefabricated substation. The electrical equipment, control systems, and other precision devices inside the prefabricated substation are extremely sensitive to moisture; moisture ingress can not only lead to equipment malfunctions but also seriously affect the substation's normal operation and safety.

[0003] In existing technologies, although there are some waterproof designs, such as the use of sealing strips or waterproof boards, these designs mostly focus on static door frame sealing. When the double doors are closed, the gaps between the door panels are still not effectively sealed, causing water to flow into the interior of the enclosure through these gaps, resulting in water leakage. This seriously affects the long-term operation and equipment safety of the prefabricated substation. Utility Model Content

[0004] The purpose of this application is to provide a waterproof double door for a prefabricated substation, which aims to solve the technical problem of water leakage through the gap between the door panels when the double door is closed in existing prefabricated substations.

When the first door panel is closed, the water-blocking component is engaged with the water guide groove, and when the second door panel is closed, the installation groove is engaged with the water-blocking component.

[0006] In one embodiment, the water guide channel includes a channel body and a sealing strip, the sealing strip being disposed on the inner wall of the channel body, and the water-blocking member engaging with the sealing strip.

[0007] In one embodiment, the water-blocking component is a U-shaped structure, which is fixedly connected to the first opening portion. The opening of the U-shaped structure faces the water guide groove, and the U-shaped structure is engaged with the sealing strip.

[0008] In one embodiment, the water-blocking component is an L-shaped structure, which is fixedly connected to the first opening portion and engages with the sealing strip.

[0009] In one embodiment, the water-blocking member is located near the top of the first door panel.

[0010] In one embodiment, the door frame includes a first frame and a second frame, which together form the door frame. The first connecting portion is rotatably connected to the first frame, and the second connecting portion is rotatably connected to the second frame.

[0011] In one embodiment, the first frame and the second frame are connected by welding.

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] With the widespread application of prefabricated substations in power systems, their waterproof performance has become a crucial factor in ensuring normal equipment operation. Traditional double-door designs typically use two doors connected to the frame by hinges, with the door's closure depending on the door panels' engagement. However, due to the double-door design, a gap is often created when the two doors are closed, which can become a pathway for water to enter the prefabricated substation. The electrical equipment, control systems, and other precision devices inside the prefabricated substation are extremely sensitive to moisture; moisture ingress can not only lead to equipment malfunctions but also seriously affect the substation's normal operation and safety.

[0021] In existing technologies, although there are some waterproof designs, such as the use of sealing strips or waterproof boards, these designs mostly focus on static door frame sealing. When the double doors are closed, the gaps between the door panels are still not effectively sealed, causing water to flow into the interior of the enclosure through these gaps, resulting in water leakage. This seriously affects the long-term operation and equipment safety of the prefabricated substation.

[0022] To address the aforementioned technical problems, this application proposes a waterproof double-door design for a prefabricated substation. Please refer to [link / reference]. Figures 1 to 3In one embodiment of this application, the waterproof double door of the prefabricated substation includes a door frame 1, a water guide channel 2, a first door panel 3, a second door panel 4, and a water-blocking component 5. The water guide channel 2 is arranged circumferentially along the door frame 1. The first door panel 3 includes a first connecting part 31 and a first opening part 32. The second door panel 4 includes a second connecting part 41 and a second opening part 42. The first connecting part 31 and the second connecting part 41 are rotatably connected to the door frame 1, respectively. When the first door panel 3 and the second door panel 4 are closed, the first opening part 32 and the second opening part 42 are in clearance fit. The water-blocking component 5 is fixedly connected to the first opening part 32. The second opening part 42 has an installation groove 43. When the first door panel 3 is closed, the water-blocking component 5 is engaged with the water guide channel 2. When the second door panel 4 is closed, the installation groove 43 is engaged with the water-blocking component 5.

[0023] The technical solution of this application employs a water guide channel 2 arranged circumferentially along the door frame 1. The first door panel 3 includes a first connecting part 31 and a first opening part 32, and the second door panel 4 includes a second connecting part 41 and a second opening part 42. The first connecting part 31 and the second connecting part 41 are rotatably connected to the door frame 1. When the first door panel 3 and the second door panel 4 are closed, the first opening part 32 and the second opening part 42 are in clearance fit. A water-blocking component 5 is fixedly connected to the first opening part 32, and the second opening part 42 has an installation groove 43. When the first door panel 3 is closed, the water-blocking component 5 is engaged with the water guide channel 2; when the second door panel 4 is closed, the installation groove 43 is engaged with the water-blocking component 5. This prevents water from entering the interior of the prefabricated substation along the gap between the first opening part 32 and the second opening part 42, which is beneficial to improving the waterproof effect of the double doors of the prefabricated substation, and thus helps to ensure the long-term operation and equipment safety of the prefabricated substation.

[0024] Please see Figure 2 In one embodiment, the water guide channel 2 includes a channel body and a sealing strip. The sealing strip is disposed on the inner wall of the channel body, and the water-blocking component 5 is engaged with the sealing strip. This embodiment, by setting a sealing strip in the water guide channel 2 and engaging the water-blocking component 5 with the sealing strip, can effectively enhance the sealing performance at the door panel closure, preventing rainwater or condensate from seeping into the interior of the enclosure through the contact area. This is beneficial to improving the waterproof reliability and service life of the prefabricated substation, ensuring the safe and stable operation of the equipment in complex environments such as high humidity and heavy rain.

[0025] Please see Figure 2 In one embodiment, the water-blocking component 5 has a U-shaped structure, which is fixedly connected to the first opening part 32. The opening of the U-shaped structure faces the water guide groove 2, and the U-shaped structure is engaged with the sealing strip. This embodiment, by using a U-shaped water-blocking component 5 fixedly connected to the first opening part 32 and engaged with the sealing strip, can enhance the sealing effect between the door panel and the water guide groove 2, effectively preventing water from entering the interior of the box-type substation through the door gap. This helps improve the waterproof performance of the substation, protects the equipment from water damage, and ensures long-term stable operation.

[0026] In one embodiment, the water-blocking component 5 has an L-shaped structure, which is fixedly connected to the first opening part 32 and engages with the sealing strip. This embodiment, by using an L-shaped water-blocking component 5 fixedly connected to the first opening part 32 and engaging with the sealing strip, enhances the sealing effect between the door panel and the water guide channel 2, effectively preventing water from entering the substation through the door gaps and improving the substation's waterproofing performance.

[0027] Please see Figure 2 In one embodiment, the water-blocking member 5 is located near the top of the first door panel 3. This embodiment, by placing the water-blocking member 5 at the top of the first door panel 3, can effectively prevent water from flowing down through the door gaps into the interior of the box-type substation. By utilizing gravity and the physical structure of the water-blocking member 5, a protective barrier is formed, thereby enhancing the waterproof effect.

[0028] Please see Figures 1 to 3 In one embodiment, the door frame 1 includes a first frame 11 and a second frame 12, which together form the door frame 1. A first connecting part 31 is rotatably connected to the first frame 11, and a second connecting part 41 is rotatably connected to the second frame 12. This embodiment can improve the sealing and stability of the door frame 1 and prevent the external environment from affecting the interior of the prefabricated substation.

[0029] In one embodiment, the first frame 11 and the second frame 12 are connected by welding. This embodiment ensures the stability and durability of the door frame 1 structure by connecting the first frame 11 and the second frame 12 by welding. The welded connection provides strong structural support, enabling the door frame 1 to maintain good stability during long-term use and preventing loosening or deformation. At the same time, welding also improves the overall sealing performance, reduces the intrusion of external factors such as water and moisture, and further enhances the safety and reliability of the prefabricated substation.

[0030] In one embodiment, the first frame 11 and the second frame 12 are connected by integral molding. This embodiment, by integrally molding the first frame 11 and the second frame 12, adopts an integrated structure, making the door frame 1 structure more compact and stable. The integral molding method not only eliminates the seams and weaknesses that may exist in traditional connection methods, but also improves the compressive strength and durability of the door frame 1. This connection method effectively enhances the integrity and strength of the door frame 1, reduces the impact of the external environment on the structure, and ensures the stability and safety of the prefabricated substation during long-term use.

[0031] In one embodiment, the water-blocking component 5 and the first opening portion 32 are fixedly connected by welding. This embodiment ensures a firm connection between the water-blocking component 5 and the opening portion by welding. This welded connection allows the water-blocking component 5 and the opening portion of the door frame 1 to form a stable whole, avoiding loosening or detachment problems that may occur due to external environment or operation, thereby improving the waterproof effect. The welded connection not only enhances the durability of the structure but also improves the sealing performance, ensuring that the water-blocking component 5 can effectively prevent water from entering the interior of the prefabricated substation through the door gaps during use.

[0032] In one embodiment, the water-blocking member 5 and the first opening portion 32 are fixedly connected by adhesive. This embodiment employs a simpler and more flexible connection method by fixing the water-blocking member 5 and the first opening portion 32 by adhesive. Adhesive connection provides good sealing performance, helps prevent moisture ingress, and also avoids problems such as heat deformation or stress concentration that may occur during welding. By using adhesive, the connected parts can bear external pressure more evenly and can be easily disassembled or replaced when needed. Adhesive fixing connection can also effectively reduce the complexity and cost of the installation process.

[0033] This application aims to protect a waterproof double-leaf door for a prefabricated substation. The technical solution employs a water guide channel 2 arranged circumferentially along the door frame 1. The first door panel 3 includes a first connecting part 31 and a first opening part 32, and the second door panel 4 includes a second connecting part 41 and a second opening part 42. The first connecting part 31 and the second connecting part 41 are rotatably connected to the door frame 1. When the first door panel 3 and the second door panel 4 are closed, the first opening part 32 and the second opening part 42 are in clearance fit. A water-blocking component 5 is fixedly connected to the first opening part 32, and the second opening part 42 has an installation groove 43. When the first door panel 3 is closed, the water-blocking component 5 is engaged with the water guide channel 2; when the second door panel 4 is closed, the installation groove 43 is engaged with the water-blocking component 5. This prevents water from entering the prefabricated substation through the gap between the first opening part 32 and the second opening part 42, improving the waterproof effect of the double-leaf door and thus ensuring the long-term operation and equipment safety of the prefabricated substation.
