Description

Technical Field

[0001] The present invention relates to the technical field of smart grids, and in particular to outdoor power transformation equipment of a smart grid. Background Art

[0002] The continuous development of smart grid technology is placing higher demands on the functionality, convenience, and safety of outdoor substation equipment. As key nodes in the power system, the proper operation of smart grid substations is crucial to ensuring the stability and reliability of power supply. Therefore, optimizing the design of outdoor equipment in smart grid substations to improve operational convenience, equipment transfer efficiency, and the working environment for maintenance personnel has become a key aspect of current technological development.

[0003] The Chinese invention with publication number CN111355179B proposes a high- and low-voltage prefabricated substation with good protection performance, including a box body, an electric power equipment cabinet, a base assembly and three protection assemblies. The base assembly includes a base plate, a bottom plate and a plurality of first elastic members. The base plate is connected to the bottom plate, and each first elastic member is connected to the side wall of the base plate. The electric power equipment cabinet is arranged on the base plate. The box cover is arranged on the bottom plate, and the box wall of the box body abuts against the bottom plate. One end of each first elastic member is connected to the inner box wall of the box body, and the other end of each first elastic member is connected to the side wall of the base plate. The box body has four side walls, one side wall of the box body is provided with an inspection door, and each side wall of the other three side walls of the box body is connected to a protection assembly. The protection assembly includes a protection plate and a plurality of second elastic members, one end of each second elastic member is connected to the protection plate, and one end of each second elastic member is connected to a side wall of the box body. The above-mentioned substation improves the safety protection performance and ensures the operational stability of the electric power equipment cabinet.

[0004] Furthermore, in traditional smart grid outdoor substation equipment, access doors typically serve only as access to the maintenance area, with a single function. Specific shortcomings include: Inconvenient installation and removal: Access doors often require complex procedures, increasing maintenance time and labor costs. Difficulty transporting equipment: When installing electrical equipment inside a substation, the lack of on-site transport vehicles makes moving and installing the equipment extremely inconvenient. Difficulty carrying maintenance tools: Maintenance personnel need to carry a variety of maintenance tools while working on-site. Carrying and storing these tools often poses a significant challenge, increasing their burden and potentially impacting maintenance efficiency due to tool loss or damage. Harsh working environment: When performing maintenance work outdoors, maintenance personnel are often exposed to adverse environmental factors such as direct sunlight, wind and rain, which not only reduces work efficiency but also poses a threat to their health. Poor stability of access doors: Once opened, access doors lack effective supports and retaining devices, making them susceptible to swinging due to wind or other external forces. This can damage equipment and pose a safety hazard to maintenance personnel.

[0005] Furthermore, in outdoor environments, maintenance personnel need a shaded area to avoid direct sunlight. Furthermore, to ensure smooth maintenance work, they also need to be able to observe the surrounding environment at all times to respond to emergencies. However, traditional maintenance door designs often fail to meet both of these requirements. Summary of the Invention

A rubber clip 29 is fixed on the top of the introduction strip 28, and the rubber clip 29 is a long strip with a circular cross-section. The annular surface of the rubber clip 29 is larger than the slot width of the slot 27. After the top of the elastic baffle 33 is inserted into the slot 25, the introduction strip 28 and the rubber clip 29 are inserted into the slot 27, and the rubber clip 29 is limited in the slot 27 to prevent the elastic baffle 33 from falling off.

[0029] When the two inspection doors 3 on one side of the smart grid substation 1 are opened, the sun visors 20 are pushed out from the reserved slots 17. When the sun visors 20 on the two inspection doors 3 are parallel to the ground, the two sun visors 20 are coplanar, and the nuts are inserted into the second slot 21 and screwed onto the studs assembled by the two connecting columns 22. At this time, the two sun visors 20 are connected together, and the two sun visors 20 form a sunshade between the two inspection doors 3 to provide shade for the maintenance personnel. In addition, the two sun visors 20 are supported between the two inspection doors 3 to prevent the two opened inspection doors 3 from swinging. That is, the two sun visors 20 not only achieve the sunshade effect, but also achieve the anti-swing limit effect on the inspection doors 3 after opening. After the sun visors 20 are folded in the reserved slots 17, they block and limit the net bag frame 31. That is, the sun visors 20 are multi-purpose and have rich functions. The finger presses the blocking bar 26 to pull the elastic blocking plate 33 down to the receiving groove 24. At this time, the window 23 is exposed, and the maintenance personnel can observe the surrounding environment through the nut.

[0030] The detailed usage of the inspection door and related components in the smart grid outdoor substation equipment is as follows: 1. Installation and disassembly of the inspection door: Pre-insert the limit shaft 5 into the through-hole 4 on the top and bottom surfaces of the inspection door 3, ensuring that both ends of the limit shaft 5 extend out of the through-hole 4 and are located in the two notches 6. Subsequently, the two connecting rings 11 are respectively mounted and fixed on both ends of the limit shaft 5. At this time, the rubber support tube 8 is in its initial state, supporting the protective sleeve 9 so that the end of the protective sleeve 9 and the end of the limit shaft 5 are coplanar. The protective sleeve 9 protects the end of the limit shaft 5 and the connecting ring 11. Push one end of the inspection door 3 into the inspection door opening 2, and use your fingers to move the protective sleeve 9 toward the mounting groove 7. The protective sleeve 9 squeezes the rubber support tube 8 to deform it, exposing the connecting ring 11. Next, use an electric drill to drill a hole through the connecting ring 11 on the surface of the inspection door opening 2, and use screws 12 to fix the connecting ring 11 to the inspection door opening 2. Finally, loosen protective sleeve 9, and rubber support tube 8 rebounds to prop up protective sleeve 9, which then repositions itself around connecting ring 11. At this point, limit axis 1-5 serves as the central axis for access door 3's rotation, allowing it to swing around limit axis 1-5, opening and closing. Remove screw 12 from connecting ring 11 to remove access door 3 from access door opening 2.

[0031] Second, using the access door as a flatbed cart: When electrical equipment needs to be installed inside smart grid substation 1 and a transfer cart is unavailable, access door 3 is removed from access door opening 2. The removed access door 3 is laid flat on the ground. Rotatably connected pulleys 15 at the top and bottom of access door 3 support access door 3, forming a flatbed cart. Electrical equipment can be placed on access door 3 and moved by pushing it forward.

[0032] III. Configuring and Using Maintenance Tools on the Access Door: Common maintenance tools (such as screwdrivers, pliers, etc.) are placed in the net bag holder 31 and placed into the tool slot 30 at the bottom of the reserved slot 17 to secure the maintenance tools within the access door 3. When the sun visor 20 is folded within the reserved slot 17, the bottom of the sun visor 20 presses against the net bag holder 31, preventing maintenance tools from jolting out of the net bag holder 31. Simultaneously, a rubber clamp 32 clamps between the sun visor 20 and the reserved slot 17, preventing the sun visor 20 from swinging freely. By rotating the sun visor 20 around the stopper shaft 3 19, the bottom of the sun visor 20 is removed from the reserved slot 17, and the top of the net bag holder 31 is exposed, allowing maintenance tools to be removed from the net bag holder 31.

[0033] Fourth, the sun visor functions as a sunshade and anti-sway limiter: When the two access doors 3 on one side of the smart grid substation 1 are opened, the sun visor 20 is extended from the reserved slot 17. When the sun visors 20 on both access doors 3 are parallel to the ground and coplanar, a nut is inserted into the second slot 21 and screwed onto the studs formed by the two connecting posts 22. The two sun visors 20 are now connected together, forming a sunshade between the two access doors 3, providing shade for maintenance personnel. The support of the two sun visors 20 prevents the two open access doors 3 from swinging, thus preventing the access doors 3 from swinging.

[0034] V. Window Usage: Press the baffle 26 with your finger to pull the elastic baffle 33 down into the storage slot 24. The window 23 is now exposed, allowing maintenance personnel to observe the surrounding environment through the window 23. Push the elastic baffle 33 upward so that its top end is inserted into the slot 25. Simultaneously, the guide bar 28 and the rubber clip 29 are inserted into the slot 27. The rubber clip 29 is retained in the slot 27, preventing the elastic baffle 33 from falling out, and the window 23 is closed.
