Description

Technical Field

[0001] This utility model relates to a box top structure, specifically a box top structure for a primary and secondary integrated ring network box, belonging to the field of ring network box technology. Background Technology

[0002] A fully integrated ring main unit (RMU) is an intelligent power distribution device that deeply integrates primary and secondary equipment in a power system. Through modular design and standardized interfaces, it integrates high-voltage side primary equipment (such as ring main units, circuit breakers, load switches, and instrument transformers) with low-voltage side secondary terminal equipment (such as protection devices, monitoring and control units, and communication modules) into a single sealed enclosure, forming an integrated device. The primary equipment includes the ring main unit (including incoming and outgoing line units and voltage transformer cabinets), high-voltage disconnect switches, etc., while the secondary equipment includes integrated substation terminals (DTUs) and intelligent monitoring and control units. The top of the ring main unit primarily serves to protect against wind, rain, and dust.

[0003] However, in current integrated ring network boxes, the top of the box is usually fixed to the box body with bolts during installation. The bolts are generally located on the outside of the box body. When the ring network box is installed outdoors, the bolts are prone to rusting due to contact with rainwater, which can cause the connection between the box body and the top of the box to loosen. Moreover, after the bolts on the outside of the box body loosen, rainwater can easily enter the inside of the box body through the gaps, damaging the electrical equipment inside the box body and affecting the normal use of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a top structure of a primary and secondary integrated ring network box in order to solve the above problems. By setting a fixing component inside the box to connect the box body and the top, the bolts are prevented from being corroded and causing the top to loosen, and rainwater is prevented from seeping into the box body and damaging the electrical equipment.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a top structure of a primary and secondary integrated ring network box, comprising a base plate and a protective mechanism mounted on the base plate. The protective mechanism includes four support frames, with support frames fixedly connected to the four corners of the base plate surface. A sealing mechanism is installed on the four support frames, and the sealing mechanism includes a box top. The box top is provided on the four support frames, and an outer frame is welded to the bottom of the box top. Two limiting strips welded to the box top are provided opposite to each other on the inner side of the outer frame. Two support frames on the same side are inserted into the outer frame on the same side and the limiting strips are welded to the box top. Between the positioning bars, four insertion holes are correspondingly opened on the inner sides of the four support frames and the two limiting bars. The side walls of the two opposing support frames are welded with shells corresponding to the insertion holes. Insert rods that are inserted into the insertion holes are slidably connected inside the four shells. Pull rods are rotatably connected to the ends of the four insert rods. Rotating seats are rotatably connected between the two opposing pull rods. Connecting plates are fixedly connected between the two rotating seats. Screws that are threaded to the top of the box are slidably connected to the connecting plates. Limiting rings that abut against the bottom of the connecting plates are fixedly connected to the screws.

[0006] Preferably, the two ends of the limiting strip are L-shaped, and the middle part of the two limiting strips is arranged parallel to the outer frame, and the outer frame is rectangular.

[0007] Preferably, the top of the box has an inverted V-shaped structure, and the bottom area of ​​the box is larger than the rectangular area formed by the four supporting structures.

[0008] Preferably, all four tie rods are inclined and have the same length.

[0009] Preferably, the protective mechanism further includes a protective door, wherein the two support frames are hinged to the protective door, a baffle is welded between the center of the base plate and the outer frame, the protective door abuts against the baffle, a protective plate is welded between two adjacent support frames, and the protective door is provided with a handle groove.

[0010] Preferably, the top of the box is provided with a heat dissipation mechanism, which includes air ducts, and multiple air ducts with L-shaped cross-sections are provided at equal intervals at both ends of the top of the box.

[0011] Preferably, the heat dissipation mechanism further includes ventilation pipes, and ventilation pipes are threadedly connected to multiple air ducts located on both sides of the top of the box. Two air inlet pipes are connected to the multiple ventilation pipes in opposite directions, and the air inlet pipes and ventilation pipes form an L-shaped structure.

[0012] Preferably, the heat dissipation mechanism further includes partitions, and L-shaped partitions are welded to the inner half of each of the plurality of ventilation pipes.

[0013] Preferably, the heat dissipation mechanism further includes an air inlet shroud, and the end of the air inlet pipe is welded with an air inlet shroud having a trumpet-shaped structure.

[0014] The beneficial effects of this utility model are as follows: The top of the box is placed on four support frames, and two support frames on the same side are inserted between the outer frame and the limiting strip on the same side. The L-shaped part of the limiting strip cooperates with the outer frame to initially clamp the support frame. The screw is rotated, and the screw is threadedly connected to the top of the box. As the screw rotates, the limiting ring pushes the connecting plate upward. After the connecting plate rises, it drives the two rotating seats to rise. Furthermore, the four pull rods move simultaneously, thereby causing the four plug rods to slide inside the outer shell until the four plug rods are simultaneously inserted into the corresponding plug holes, thus fixing the top of the box to the support frame. This avoids the bolts being exposed and causing rust, which could lead to the top of the box loosening. It also prevents water from seeping into the electrical equipment and damaging it.

Four insertion holes 311 are provided on the side and the two limiting strips 303 respectively. The side walls of the two opposing support frames 201 are welded with outer shells 304 corresponding to the insertion holes 311. The inside of each of the four outer shells 304 is slidably connected to the insertion rods 310 that are inserted into the insertion holes 311. The ends of the four insertion rods 310 are rotatably connected to the pull rods 308. The two opposing pull rods 308 are rotatably connected to the rotating seat 307. The two rotating seats 307 are fixedly connected to the connecting plate 305. The connecting plate 305 is slidably connected to the screw rod 306 that is threaded to the top of the box 301. The screw rod 306 is fixedly connected to the limiting ring 309 that abuts against the bottom of the connecting plate 305.

[0027] As a technical optimization of this utility model, the two ends of the limiting strip 303 are L-shaped, and the middle part of the two limiting strips 303 is arranged parallel to the outer frame 302. The outer frame 302 is rectangular, so that the L-shaped part of the limiting strip 303 and the outer frame 302 can clamp the support frame 201.

[0028] As a technical optimization of this utility model, the top of the box top 301 has an inverted V-shaped structure, and the bottom area of ​​the box top 301 is larger than the rectangular area formed by the four support frames 201, so as to achieve comprehensive protection for the assembled box.

[0029] As a technical optimization of this utility model, all four pull rods 308 are inclined and have the same length, so that the four pull rods 308 move simultaneously to drive the insertion rod 310 to slide inside the outer shell 304, so that the four insertion rods 310 are inserted into the insertion hole 311 at the same time.

[0030] As a technical optimization of this utility model, the protective mechanism 2 also includes a protective door 202, wherein the protective door 202 is hinged to the two support frames 201 by hinges 204, a baffle 206 is welded between the center of the bottom plate 1 and the outer frame 302, the protective door 202 abuts against the baffle 206, a protective plate 205 is welded between two adjacent support frames 201, and a handle groove 203 is provided on the protective door 202, so as to realize the protection of electrical components by the box composed of the four support frames 201, the protective plate 205 and the protective door 202.

[0031] As a technical optimization of this utility model, a heat dissipation mechanism 4 is provided on the top of the box 301. The heat dissipation mechanism 4 includes air ducts 404. Multiple air ducts 404 with L-shaped cross-sections are provided at equal intervals at both ends of the top of the box 301. The heat dissipation mechanism 4 also includes ventilation pipes 401. Ventilation pipes 401 are threadedly connected to the multiple air ducts 404 located on both sides of the top of the box 301. Two air inlet pipes 402 are connected to the multiple ventilation pipes 401. The air inlet pipes 402 and the ventilation pipes 401 form an L-shaped structure. The heat dissipation mechanism 4 also includes... The heat dissipation mechanism 4 includes a partition 405, and an L-shaped partition 405 is welded to the inner half of the multiple ventilation pipes 401. The heat dissipation mechanism 4 also includes an air inlet shroud 403. The end of the air inlet pipe 402 is welded with an air inlet shroud 403 with a trumpet-shaped structure. The air inlet pipes 402 in both directions facilitate the entry of air into the interior of the ventilation pipes 401. Finally, the air enters the interior of the air duct 404 to dissipate heat from the electrical components. The air inlet shroud 403 facilitates the entry of air, and the partition 405 facilitates the entry of air from both directions into the interior of the air duct 404.

[0032] In use, the four support frames 201 are first fixedly installed at the four corners of the base plate 1 to ensure their stable installation and provide a stable foundation for subsequent component installation. The top of the box 301 is then placed on the four support frames 201, with two support frames 201 on the same side inserted between the outer frame 302 and the limiting strip 303 on the same side. At this point, the L-shaped portion of the limiting strip 303 cooperates with the outer frame 302 to initially clamp the support frame 201. Because the limiting strip 303 has an L-shaped structure at both ends and a middle portion... Parallel to the outer frame 302, which has a rectangular structure, the outer frame 302 effectively achieves initial positioning. A rotating screw 306, threadedly connected to the top of the housing 301, rotates. As the screw 306 rotates, the limiting ring 309 pushes the connecting plate 305 upwards. The rising connecting plate 305 then drives the two rotating seats 307 upwards, further causing the four pull rods 308 to move simultaneously, thereby allowing the four insertion rods 310 to slide inside the outer shell 304 until all four insertion rods 310 are simultaneously inserted into their corresponding insertion holes 311, thus completing the housing positioning. The top 301 is fixed to the support frame 201 to prevent exposed bolts from rusting and causing the top 301 to loosen, and to prevent water from seeping into the electrical equipment and damaging it. A baffle 206 is welded between the center of the bottom plate 1 and the outer frame 302 to ensure that the protective door 202 can contact the baffle 206 when closed, thus providing a sealing and protective function. A protective plate 205 is welded between two adjacent support frames 201, which, together with the support frame 201 and the protective door 202, form a complete enclosure to protect the internal electrical components. The door 202 is provided with a handle groove 203 for easy opening and closing of the protective door 202; finally, ventilation pipes 401 are threadedly connected to multiple air ducts 404 with L-shaped cross sections that are equidistantly arranged at both ends of the top of the box 301, and two air inlet pipes 402 are connected to each other on the multiple ventilation pipes 401, so that the air inlet pipes 402 and the ventilation pipes 401 form an L-shaped structure, which facilitates air intake from different directions and is conducive to heat dissipation of electrical equipment. The air inlet cover 403 is conducive to the collection of air. The two partitions 405 are conducive to the simultaneous intake of air from different directions and reduce resistance.
