Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a waterproof and corrosion-resistant prefabricated substation. Background Technology

[0002] Prefabricated substations are also commonly known as box-type substations or "box-type transformers".

[0003] Because prefabricated substations are typically located outdoors, they are susceptible to corrosion due to high moisture content from rain, snow, and other weather conditions. This corrosion can fundamentally compromise the structural integrity and electrical safety of the prefabricated structure. Therefore, most existing prefabricated substations not only have an anti-rust coating applied to the outer casing but also feature a waterproof eaves on the top. These protruding eaves guide rainwater away from the enclosure or prevent direct impact, effectively reducing direct water erosion and congestion. This minimizes continuous corrosion to the casing surface, providing both waterproofing and corrosion resistance.

[0004] However, as the topmost protruding component of the enclosure, the waterproof eaves are directly exposed to all climatic factors, including sunlight, rain, and ultraviolet radiation. Therefore, the waterproof eaves are the most susceptible to corrosion in the entire waterproof and corrosion-resistant prefabricated substation. As corrosion occurs, pits form on the eaves, accumulating rainwater, dust, fallen leaves, and other pollutants, creating a persistently damp local environment that exacerbates corrosion. Furthermore, for ease of substation installation, traditional waterproof eaves are usually designed as an integral part of the enclosure, requiring the filling of pits for repair. This repair process can easily damage the surface structure of the waterproof eaves, affecting its ability to guide water flow. Utility Model Content

[0005] The main purpose of this utility model is to provide a waterproof and corrosion-resistant prefabricated substation, which aims to solve the problem in related technologies that when maintaining the waterproof and corrosion-resistant performance of the substation (repairing the waterproof eaves), the surface structure is easily damaged, affecting the guiding effect on water flow.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A waterproof and corrosion-resistant prefabricated substation includes a shell, on which a waterproof eave is provided. The waterproof eave includes an eave frame and a waterproof board. The waterproof board is detachably connected to the eave frame, and the eave frame is fixedly connected to the shell.

[0008] Furthermore, the waterproof membrane includes several plates, each plate being symmetrically and evenly distributed around the shell; each plate has a connecting rod at one end close to the shell, and each connecting rod and the shell have several first fixing members for fixing the two, each first fixing member being threadedly connected to the shell.

[0009] Furthermore, the eaves frame includes a connecting beam and several mounting frames, each of which is arranged sequentially on the shell along a linear direction. The waterproof board is located on each mounting frame, and the connecting beam passes through each mounting frame.

[0010] Furthermore, the connecting beam is provided with several fixing slots for each plate to be embedded.

[0011] Furthermore, each mounting frame adjacent to the end face of the waterproof membrane is provided with a baffle strip, and the waterproof membrane is located between the baffle strips.

[0012] Furthermore, each of the mounting frames is provided with a mounting groove for placing the connecting beam, and a connecting plate for fixing the connecting beam to each mounting frame is provided between the connecting beam and each mounting frame.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] like Figure 1As shown, this embodiment proposes a waterproof and corrosion-resistant prefabricated substation, mainly including a shell 1. The distribution of electrical components inside the shell 1 should be determined according to the location and application requirements of this embodiment, and will not be described in detail here. A waterproof eaves 2 is provided on the shell 1. The waterproof eaves 2 mainly includes an eaves frame 21 and a waterproof plate 22. The eaves frame 21 is fixedly connected to the shell 1, while the waterproof plate 22 is detachably connected to the eaves frame 21. That is, this embodiment adopts the method of directly replacing the waterproof plate 22, which fundamentally solves the problem that the water flow surface of the waterproof eaves 2 is easily uneven when the corrosion resistance is maintained by coating (traditional maintenance method). This effectively avoids the impact of the maintenance of the waterproof eaves 2 on its water flow guidance performance.

[0030] like Figures 2-5 As shown, the eaves frame 21 includes several mounting frames 212, which are arranged sequentially on the shell 1 along a linear direction. The waterproof board 22 is located on each mounting frame 212, that is, each mounting frame 212 serves to support the waterproof board 22.

[0031] Meanwhile, the waterproof membrane 22 includes several plates 221, which are symmetrically and evenly distributed around the shell 1 to ensure the stress balance of the shell 1 when supporting the waterproof membrane 22 (waterproof eaves 2). Correspondingly, each mounting frame 212 is an isosceles triangular structure, and each plate 221 is distributed along the inclined surface of each mounting frame 212. While ensuring the symmetrical distribution of each plate 221, it also creates an inclined angle with the horizontal plane, allowing rainwater falling on the waterproof membrane 22 to quickly run off along its surface.

[0032] In order to achieve the detachable connection of each plate 221 (waterproof plate 22) on the eaves frame 21, each plate 221 is provided with a connecting rod 222 at the end close to the shell 1. Each connecting rod 222 and the shell 1 are provided with a number of first fixing parts 3 for fixing the two. Each first fixing part 3 is threadedly connected to the shell 1. That is, this embodiment uses the threaded structure to realize the installation of each plate 221 on the shell 1 and the eaves frame 21, which not only ensures the installation strength, but also ensures the convenience of subsequent disassembly and assembly.

[0033] Each connecting rod 222 is located between the two ends of each plate 221, effectively preventing water from flowing to the connection point between each plate 221 and the shell 1, reducing the possibility of external factors interfering with the connection between the two (such as causing the thread features between the two to rust), thereby ensuring the stability of the connection between the two.

[0034] Furthermore, the eaves frame 21 also includes a connecting beam 211, which passes through each mounting frame 212, so that the shell 1 has a protrusion structure on both sides, so that the crane can be easily connected to the embodiment during subsequent installation, thereby improving the installation and construction efficiency of the embodiment.

[0035] Meanwhile, the connecting beam 211 is provided with a number of fixing slots 2111 for each plate 221 to be embedded, so that each plate 221 has a support point at both ends in this embodiment, which effectively strengthens the fixing effect of each plate 221.

[0036] Correspondingly, each fixing slot 2111 is parallel to each inclined surface of the mounting frame 212. Thus, during the installation of each plate 221, each plate 221 is moved along the surface of the mounting frame 212, so that each plate 221 can be embedded into each fixing slot 2111.

[0037] Each mounting frame 212 adjacent to the end face of the waterproof membrane 22 is provided with a baffle 213. The waterproof membrane 22 is located between the baffles 213. That is, the presence of each baffle 213 covers the side part of the waterproof membrane 22, preventing the waterproof membrane 22 from deforming or even being lifted by strong winds in windy weather, thus effectively enhancing the structural stability of this embodiment in windy weather.

[0038] Each mounting frame 212 is provided with a mounting groove 2121 for placing the connecting crossbeam 211, so that each mounting frame 212 (mounting groove 2121) provides a surface contact support for the connecting crossbeam 211, rather than just a point or line contact. Furthermore, a connecting plate 4 is provided between the connecting crossbeam 211 and each mounting frame 212 for fixing the two together. Thus, when the connecting crossbeam 211 is subjected to downward pressure or bending force, the force can be transmitted through the connecting plate 4 to the sidewalls and bottom of the mounting groove 2121, and then distributed throughout the entire mounting frame 212. This greatly enhances the overall load-bearing capacity and deformation resistance of this embodiment.

[0039] Each connecting plate 4 has an "L" shaped structure; a second fixing member 5 and a third fixing member 6 are respectively provided between each connecting plate 4 and the mounting frame 212 and between each connecting plate 4 and the connecting beam 211. The second fixing member 5 and the third fixing member 6 are respectively threaded to the mounting frame 212 and the connecting beam 211.

[0040] The natural right-angle crank arm structure of the "L"-shaped plate makes it easier for the second fixing member 5 and the third fixing member 6 to connect the mounting frame 212 and the connecting beam 211 respectively. In this way, the mounting frame 212 is locked from the side (Y-axis) by the second fixing member 5, and the connecting beam 211 is locked from the front (X-axis) by the third fixing member 6. The combined force of these two vertical directions forms a solid right-angle constraint, completely eliminating any loosening, wobbling or rotation tendency that may occur in the connecting beam 211 within the mounting groove 2121.

[0041] This connection method can not only withstand vertical downward pressure, but also effectively resist shear forces and torsional moments from the front-back and left-right directions. This makes the waterproof eaves 2 (eaves frame 21) more reliable when facing vibration, impact or eccentric load.

[0042] Each mounting frame 212 has a connecting plate 4 on both the left and right sides, so that both sides of each mounting frame 212 can provide support for the connecting beam 211, further enhancing the overall stability of the waterproof eaves 2 (eaves frame 21).

[0043] In this embodiment, each of the first fastener 3, the second fastener 5, and the third fastener 6 is preferably a common threaded fastener such as a bolt with a nut, so that a replacement can be quickly found if any fastener is accidentally lost.
