Description

Technical Field

[0001] This utility model is a detachable roof cover for high-voltage substations, belonging to the field of substations. Background Technology

[0002] A substation is a power system that transforms voltage, receives and distributes electrical energy, controls the flow of electricity, and adjusts voltage. In order to transmit the electrical energy generated by the power plant to a distant place, the voltage must be increased to become high voltage, and the voltage needs to be reduced near the user.

[0003] Substations typically have roof panels installed on their roofs. However, these roof panels are usually directly welded to the roof of a high-voltage substation or fixed to it with a large number of bolts. This makes it difficult to disassemble and replace roof panels that have been damaged by rain and other factors. The process of replacing roof panels is time-consuming and labor-intensive for workers, which greatly reduces their work efficiency and increases their workload. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a detachable roof cover for high-voltage substations to solve the problems mentioned in the background art. The detachable roof cover for high-voltage substations can provide a convenient roof cover installation method.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a detachable roof cover for high-voltage substations, comprising a steel frame, wherein an installation opening is provided at one end of the top of the steel frame;

[0006] The top end of the steel frame is provided with an assembly mechanism for easy installation. The assembly mechanism includes an assembly frame, which is installed at one end of the top of the steel frame and is connected to the installation opening. A top plate is placed on the top of the steel frame, and a middle folded edge is installed at the bottom of the top plate. A bottom sealing plate is installed at the bottom of the middle folded edge, and both the middle folded edge and the bottom sealing plate are located inside the cavity of the assembly frame. A lifting block is installed on the top of the top plate.

[0007] The assembly frame is provided with protective mechanisms for the connection of the roof cover on both sides. The protective mechanism includes a clamping base plate, and an installation plate is provided on one side of the clamping base plate.

[0008] Furthermore, a lower fixed C-frame is placed below the top of both sides of the assembly frame. Each of the two lower fixed C-frames has a fixed pin arrayed on one side of its top, and the fixed pins pass through the fixed pin holes opened on both sides of the top of the assembly frame and the top of the top plate.

[0009] Furthermore, upper fixed C-frames are placed on both sides of the top of the top plate, and limit holes are opened on the top of the fixed card holes. Reinforcing card posts are arranged in an array at both ends of the bottom of the two upper fixed C-frames, and the reinforcing card posts are inserted into the limit card holes one by one. Bolt holes are opened on both sides of both ends of the top of the top plate.

[0010] Furthermore, bolt holes are provided at both ends of the top of the two upper fixed C-frames and both ends of the top of the lower fixed C-frames, and fastening bolts are installed in the bolt holes.

[0011] Furthermore, each of the mounting plates has an adjusting stud installed at the center of its top, and an assembly ear plate is fitted onto the center of the outer side of each adjusting stud. One side of each assembly ear plate is connected to the center of one side of the protective cover.

[0012] Furthermore, auxiliary rods are installed at both ends of the top of the mounting plate, and auxiliary ear plates are provided at both ends of one side of the protective cover. The auxiliary rods pass through the auxiliary ear plates one by one. Sealing strips are provided at the bottom of the protective cover. The clamping base plate contacts the two ends of the bottom of the two lower fixed C-frames respectively. The protective cover contacts the two ends of the top of the two upper fixed C-frames respectively, and the tops of the fastening bolts are all located inside the protective cover.

[0013] The beneficial effects of this utility model are:

[0014] 1. The assembly mechanism makes the roof panels easy to disassemble and replace, greatly improving the work efficiency of the staff and reducing the workload. It avoids the inconvenience of disassembly and assembly by direct welding and other methods, which would affect the efficiency and workload of disassembly and assembly.

[0015] 2. The assembly mechanism greatly reduces the use of bolts during assembly, improving the convenience of disassembly and assembly.

[0016] 3. The fixed pins pass through the fixed pin holes of the assembly frame and the top plate in sequence, while the reinforcing pins of the upper fixed C-frame are inserted into the limiting pin holes one by one. This improves the stability of the assembly between the upper fixed C-frame, the lower fixed C-frame and the assembly frame, and enhances the reliability of the assembly mechanism.

[0017] 4. Protect the fastening bolts that fix the roof panel to the steel frame using a protective mechanism to prevent the fastening bolts and bolt holes from being corroded by rainwater and other external forces over a long period of time, which could cause rust and affect the stability of the roof panel installation, thus preventing the roof panel from loosening and falling off.

[0018] 5. Use protective covers to reduce the impact of external forces such as rainwater on fastening bolts and bolt holes, prevent rust between fastening bolts and bolt holes, and make fastening bolts and bolt holes easier to disassemble and assemble. Attached Figure Description
