Description

Technical Field

[0001] The present application relates to the technical field of ring network boxes, and in particular to a primary and secondary fused complete ring network box. Background Art

[0002] The primary and secondary integrated ring main box is an electric power distribution equipment that integrates the functions of primary and secondary equipment. By integrating the distribution, protection and control functions of the high-voltage side and the low-voltage side into one device, it realizes the distribution, regulation, protection and control of the power system, thereby improving the reliability and safety of the power system. It is suitable for urban power grids, industrial electricity and large buildings and other places.

[0003] Since the ring network box integrates more functions, its structure is relatively complex and requires regular and timely maintenance. In the related art, the ring network box includes a box body, a first box door installed on the front and back of the box body, a second box door installed on the two sides of the box body, and electrical equipment installed inside the box body. During maintenance, the box door can be opened in all directions to fully expose the electrical equipment, which is convenient for staff to inspect.

[0004] Since the front width of most ring network boxes is generally more than 3m, the first box door often adopts a folding door structure, which is not only convenient to open or close, but also reduces the space occupied by the first box door after it is opened. However, the high freedom of movement of the first box door will also make it inconvenient to fix it after opening. In outdoor scenes, it is easy to be hit by wind and hit the maintenance personnel, which needs to be improved. Summary of the invention

[0005] In order to facilitate the fixation of the main door after it is opened, the present application provides a one- and two-stage fused ring mesh box.

[0006] The present application provides a one-two fusion ring network box that adopts the following technical solution:

[0007] A primary and secondary fused ring net box comprises a box body, wherein the front and back sides of the box body are connected with main doors, the two opposite sides of the box body are hinged with side doors, the main door comprises two sliding doors and a rotating door hinged with the sliding doors, the sliding doors are slidably connected to the box body, a door locking device is arranged between the two rotating doors, the rotating doors are connected with card blocks, and the outer side of the sliding door is provided with a card slot for inserting the card block.

[0008] By adopting the above technical solution, when the main door needs to be opened for maintenance, the door locking device is opened, and the rotating door is pulled to rotate 180 degrees until it fits with the sliding door, so that the card block is inserted into the card slot, and the rotating door and the sliding door are relatively fixed, exposing the internal electrical equipment. On the one hand, the main door is not easily moved by wind after it is opened, avoiding the risk of maintenance personnel being hit during maintenance; on the other hand, the main door occupies little space after it is opened, and it is convenient for maintenance personnel to carry out maintenance by sliding left and right. The main door of the present application combines the advantages of sliding doors and rotating doors, is easy to open and fix, and is suitable for main doors with a width greater than 3m.

[0009] Optionally, the sliding door is connected to a connecting rod along the vertical sliding, the slot is connected to a sliding hole for the connecting rod to slide, a ring is connected to the outside of the connecting rod, the sliding hole is connected to a limiting cavity for the ring to slide, a spring is arranged between the inner wall of one end of the limiting cavity close to the slot and the ring, a card hole for inserting a card block is arranged at the end of the connecting rod extending into the slot, a chamfer is arranged on one side of the card block, and an inclined surface is arranged on the inner wall of the end of the card hole facing away from the spring.

[0010] By adopting the above technical solution, when the main door is opened, during the process of inserting the card block into the card slot, the inclined surface is subjected to the force of the card block, causing the connecting rod to slide axially, driving the spring to compress, thereby enhancing the fastening effect of the card block. A certain force is required to separate the rotating door and the sliding door.

[0011] Optionally, one end of the connecting rod away from the slot extends out of the sliding door, four connecting rods are provided and are respectively located at the four corners of the sliding door, the box body is provided with an annular groove for the main door to be inserted into, and the upper and lower ends of the annular groove are connected to sliding grooves for the ends of the connecting rod to be inserted into.

[0012] Optionally, a first sealing ring is provided on a side of the sliding door close to the box body, a second sealing ring is provided on a side of the rotating door close to the box body, and the slide groove is divided into a door closing section, a tilting section and a door opening section in sequence along the direction of the sliding door close to the rotating door;

[0013] When the connecting rod is in the door closing section, the first sealing ring is pressed against the bottom wall of the annular groove; when the connecting rod is in the door opening section, there is a gap between the first sealing ring and the bottom wall of the annular groove.

[0014] By adopting the above technical solution, the disadvantage of poor sealing of the sliding door is overcome. When the sliding door slides to the point where the connecting rod is in the door closing section, the sliding door is closer to the bottom wall of the annular groove, so that the first sealing ring is subjected to extrusion force, thereby improving the sealing of the sliding door. In addition, the sliding door has the advantage of being easy to open and close. When the connecting rod is separated from the door closing section, the friction between the first sealing ring and the inner wall of the annular groove is reduced, making it easy for the sliding door to slide.

[0015] Optionally, the door closing section is connected to a positioning groove for the end of the connecting rod to be inserted into, and when the clamping block is inserted into the connecting rod, it can drive the connecting rod to be separated from the positioning groove.

[0016] By adopting the above technical solution, only when the rotating door is opened to fit the sliding door, the block is inserted to drive the connecting rod to slide axially, the connecting rod is disengaged from the positioning groove, and the sliding door can slide.

[0017] Optionally, a heat dissipation hole is provided at the bottom of the sliding door, and a rain shield is provided on the upper side of the heat dissipation hole.

[0018] By adopting the above technical solution, rainwater can be prevented from flowing into the box through the heat dissipation holes, thereby reducing the risk of electrical equipment being damaged by moisture.

[0019] Optionally, a rainproof plate facing the heat dissipation holes is provided inside the box body, a water conducting cavity is provided from the inner bottom wall to the outer edge of the bottom of the box body, and the water conducting cavity is provided on the side of the rainproof plate close to the main door.

[0020] By adopting the above technical solution, even if a little rainwater splashes in from the lower end of the heat dissipation hole, the rainproof plate can still block it, so that the rainwater flows out again along the water guide cavity.

[0021] Optionally, the rain shield is connected to a connecting strip, the connecting strip is connected to the sliding door, and the lower end of the rain shield is connected to a sealing strip that presses against the bottom wall of the box body.

[0022] By adopting the above technical solution, the rain shield moves with the sliding door, and when the sliding door is removed, the rain shield can also be taken out together, without affecting the disassembly and assembly of the electrical equipment.

[0023] Optionally, a connecting groove communicating with the sliding hole is provided on the inner side of the sliding door, and a connecting block is connected between the connecting rod and the connecting strip.

[0024] By adopting the above technical solution, the rain shield is acted upon by the spring, so that the sealing strip is pressed tightly against the bottom wall of the box body, and rainwater cannot flow to the electrical equipment through the gap between the rain shield and the bottom wall of the box body.

[0025] In summary, this application has the following beneficial effects:

[0026] 1. The main door of the present application combines the advantages of a sliding door and a rotating door, is easy to open and fix, and is suitable for main doors with a width greater than 3m.

[0027] 2. The disadvantage of poor sealing of the sliding door is overcome by the segmented setting of the sliding groove. When the sliding door slides to the point where the connecting rod is in the door closing section, the sliding door is closer to the bottom wall of the annular groove, so that the first sealing ring is subjected to extrusion pressure, thereby improving the sealing of the sliding door.

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] The embodiment of the present application discloses a one- and two-stage fused ring mesh box.

[0038] Reference Figure 1 , 2 The primary and secondary fusion ring network box comprises a box body 1. The front and back of the box body 1 are connected with main doors 2. The two opposite sides of the box body 1 are hinged with side doors 3 through hinges. The four sides of the box body 1 can be opened to facilitate maintenance personnel to conduct a comprehensive inspection.

[0039] Reference Figure 1The main door 2 includes two sliding doors 21 and two rotating doors 22. The two rotating doors 22 are located between the two sliding doors 21. The rotating doors 22 and the sliding doors 21 are hinged one by one through hinges. The sliding door 21 is connected to the box body 1 in a lateral sliding manner, and a door locking device 4 is provided between the two rotating doors 22. The specific structure of the door locking device 4 is prior art and will not be described here. After opening the door locking device 4, the rotating door 22 can be rotated outward until the rotating door 22 fits the sliding door 21, and then by pulling the sliding door 21 left and right, the internal electrical equipment can be exposed for inspection by maintenance personnel. After the main door 2 is opened, it occupies a small space and is not easily moved by wind, which avoids the risk of maintenance personnel being hit during maintenance, and is convenient for maintenance personnel to carry out maintenance. It is suitable for use in main doors 2 with a width greater than 3m.

[0040] Reference Figure 1 , Figure 2 The sliding door 21 and the lower end of the side are both provided with heat dissipation holes 214. The heat dissipation holes 214 are strip-shaped and are provided with seven holes at intervals along the vertical direction, so as to facilitate the circulation of air inside and outside the box 1, release the internal heat, and prevent the electrical equipment from being damaged by overheating. A rain shield 215 is provided on the upper side of the heat dissipation hole 214. The rain shield 215 is fixedly connected to the box 1 to prevent rainwater from flowing into the box 1 along the heat dissipation hole 214, thereby reducing the risk of electrical equipment being damaged by moisture.

[0041] Reference Figure 3 , Figure 4 The four corners of the rotating door 22 are fixedly connected with blocks 23, and the sliding door 21 is provided with four slots 211 for the blocks 23 to be inserted into. The four corners of the sliding door 21 are connected with connecting rods 24 in a vertical sliding manner, and the sliding door 21 is provided with sliding holes 212 for the connecting rods 24 to slide vertically, and the sliding holes 212 are connected with the corresponding slots 211. A collar 241 is fixedly sleeved on the outside of the connecting rod 24, and the sliding hole 212 is connected with a limiting cavity 213 for the collar 241 to slide vertically. A spring 25 is fixedly connected between the inner wall of one end of the limiting cavity 213 close to the slot 211 and the collar 241, and the spring 25 applies a thrust to the collar 241 to move away from the slot 211. The end of the connecting rod 24 extending into the slot 211 is provided with a locking hole 242 for inserting the locking block 23, and the inner wall of the end of the locking hole 242 away from the spring 25 is provided with an inclined surface 243, so that the locking block 23 acts on the connecting rod 24 and drives the connecting rod 24 to slide axially. A chamfer 231 corresponding to the inclined surface 243 is provided on one side of the locking block 23 to increase the contact area between the locking block 23 and the connecting rod 24. In order to facilitate the insertion of the locking block 23 into the locking hole 242, the width of the locking block 23 is smaller than the inner width of the locking hole 242.

[0042] When the main door 2 needs to be opened for inspection, the door locking device 4 is opened, and the rotating door 22 is pulled to rotate 180 degrees until it fits with the sliding door 21, so that the block 23 is inserted into the slot 211. The inclined surface 243 is acted upon by the block 23, causing the connecting rod 24 to slide axially, driving the spring 25 to be compressed, thereby enhancing the fastening effect of the block 23. A certain amount of force is required to separate the rotating door 22 and the sliding door 21 to prevent the rotating door 22 from accidentally moving.

[0043] Reference Figure 1 , Figure 3 The box body 1 is provided with an annular groove 11 for the main door 2 to be inserted into, a first sealing ring 5 is fixedly connected to one side edge of the sliding door 21 close to the box body 1, and a second sealing ring 6 is fixedly connected to one side edge of the rotating door 22 close to the box body 1. When the door is closed, the first sealing ring 5 and the second sealing ring 6 are both pressed against the inner bottom wall of the annular groove 11 to ensure sealing.

[0044] Reference Figure 3 , Figure 4 In order to facilitate the sliding of the sliding door 21 when the door is opened, the end of the connecting rod 24 away from the card slot 211 extends out of the sliding door 21, and the upper and lower ends of the annular groove 11 are connected with the sliding groove 12 for the end of the connecting rod 24 to be inserted. The sliding groove 12 is divided into a closing section 121, an inclined section 122 and a door opening section 123 in sequence along the direction in which the sliding door 21 approaches the rotating door 22. When the connecting rod 24 is in the closing section 121, the first sealing ring 5 is pressed against the bottom wall of the annular groove 11, thereby overcoming the shortcoming of poor sealing of the sliding door 21 and ensuring the sealing.

[0045] When the connecting rod 24 is in the door opening section 123, there is a gap between the first sealing ring 5 and the bottom wall of the annular groove 11. When the connecting rod 24 moves from the door closing section 121 to the door opening section 123, the sliding door 21 gradually moves away from the box body 1, so that the first sealing ring 5 is gradually loosened, reducing the friction force on the sliding door 21 during the sliding process. When the sliding door 21 slides to the point where the connecting rod 24 is in the door closing section 121, the sliding door 21 is closer to the bottom wall of the annular groove 11, so that the first sealing ring 5 is subjected to a squeezing force, thereby improving the sealing performance at the sliding door 21.

[0046] Reference Figure 3 , Figure 4 The door closing section 121 is connected to a positioning groove 13 for the end of the connecting rod 24 to be inserted. When the door is closed, the collar 241 presses against the inner wall of the end of the limiting cavity 213 away from the clamping groove 211, and the end of the connecting rod 24 is inserted into the positioning groove 13. When the door is opened, the rotating door 22 rotates to fit the sliding door 21, and the clamping block 23 is inserted into the connecting rod 24 to drive the connecting rod 24 to slide axially, so that the connecting rod 24 is separated from the positioning groove 13, and the sliding door 21 can slide. When the connecting rod 24 abuts against the inner wall of the end of the clamping groove 211 away from the limiting cavity 213, the connecting rod 24 is completely retracted into the sliding hole 212, and the sliding door 21 can be separated from the annular groove 11 and removed.

[0047] Reference Figure 1 , Figure 6 A rain shield 7 is provided inside the box body 1, facing the heat dissipation hole 214. A water conducting cavity 14 is provided from the inner bottom wall of the box body 1 to the outer edge of the bottom. The water conducting cavity 14 is provided on the side of the rain shield 7 close to the main door 2. When part of the rainwater splashes into the box body 1 from the lower end of the heat dissipation hole 214, the rain shield 7 can still block it, so that the rainwater flows out again along the water conducting cavity 14.

[0048] Reference Figure 6 , Figure 7 The side of the rain shield 7 close to the sliding door 21 is fixedly connected with a connecting strip 8, and both ends of the connecting strip 8 are fixedly connected with connecting blocks 10. The sliding door 21 is provided with a connecting groove 216 for the connecting block 10 to slide up and down. The connecting groove 216 is communicated with the sliding hole 212, and the connecting block 10 is fixedly connected with the connecting rod 24. The lower end of the rain shield 7 is fixedly connected with a sealing strip 9 that presses against the inner bottom wall of the box body 1. On the one hand, the rain shield 7 moves with the sliding door 21, and when the sliding door 21 is removed, the rain shield 7 can also be taken out together, which does not affect the disassembly and assembly of the electrical equipment. On the other hand, the rain shield 7 is subjected to the force of the spring 25, so that the sealing strip 9 presses against the inner bottom wall of the box body 1, and rainwater cannot flow from the gap between the rain shield 7 and the inner bottom wall of the box body 1 to the electrical equipment.

[0049] The implementation principle of the primary and secondary fusion ring network box in the embodiment of the present application is:

[0050] When the electrical equipment needs to be repaired, the door locking device 4 is opened, and the rotating door 22 is pulled to rotate 180 degrees until it fits with the sliding door 21, so that the block 23 is inserted into the connecting rod 24, and the connecting rod 24 moves close to the slot 211 to disengage from the positioning slot 13, and then the sliding door 21 is pulled left and right to expose the corresponding part of the electrical equipment for inspection by maintenance personnel.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
