In short, ring main units are indispensable power distribution equipment in the power system. During installation and use, ring main units facilitate the rapid assembly and maintenance of the rear cover plate, making operation simple and convenient, and improving the ease of rapid assembly of the rear cover plate when the main body of the ring main unit is damaged during installation and use.

[0003] Existing ring main units require the rear cover plate to be directly closed onto the rear surface of the ring main unit during installation and use. This is then secured with multiple screws using external tools. This method of securing the ring main unit with multiple screws is inconvenient for quick assembly. Furthermore, when the ring main unit suffers internal damage after prolonged use and requires repair, the reverse process—removing multiple screws—is cumbersome and hinders the ease of quick reassembly of the rear cover plate in case of damage. Therefore, this invention proposes a quick-assembly ring main unit structure. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a quick-assembly ring network box structure, including a ring network box body 100, the ring network box body 100 including a main box 101, a box cover 102 provided at the bottom of the front surface of the main box 101, an inlet / outlet sleeve 103 provided at the top of the rear surface of the main box 101, a rear cover plate 104 provided on the rear surface of the main box 101, and the ring network box body 100 also includes:

[0024] The quick assembly mechanism includes a snap-fit ​​mounting component on the rear surface of the main housing 101. Both ends of the rear surface of the main housing 101 are provided with elastic locking components, and one side of the elastic locking component is provided with a rotational reinforcement component. This mechanism allows for quick assembly and disassembly of the rear cover plate 104 during installation and use. The assembly and disassembly operations are simple and convenient, requiring no tools to disassemble or reassemble multiple screws, thus improving the ease of quick assembly of the rear cover plate 104 in case of damage during installation and use.

[0025] To facilitate the rapid assembly of the rear cover 104 using the snap-fit ​​installation assembly, in this embodiment, preferably, the snap-fit ​​installation assembly includes a closed groove 1011 located in the middle of the rear surface of the main housing 101. Slots 1012 are provided at both ends of the closed groove 1011. A snap-fit ​​plate 1013 is integrally formed at both ends of the inner surface of the rear cover 104. The rear cover 104 is connected to the interior of the closed groove 1011 via the snap-fit ​​plate 1013 and the slots 1012. The snap-fit ​​plate 1013 engages with the slots 1012 to quickly snap-fit ​​and install the rear cover 104. Conversely, it can be quickly disassembled during maintenance, facilitating rapid assembly and making the operation simple and convenient.

[0026] To facilitate quick assembly and lock the rear cover 104 after installation using the elastic locking assembly, this embodiment preferably includes two limiting grooves 1016 at both ends of the closing groove 1011. A limiting block 1018 is positioned inside the limiting groove 1016. An elastic block 1017 is provided at the connection between the end of the limiting block 1018 and the bottom of the limiting groove 1016. The elastic block 1017 elastically connects the limiting block 1018 within the limiting groove 1016, facilitating elastic locking installation. Two locking holes 1015 are provided at both ends of the rear cover 104. The internal structure of the limiting block 1018 matches the locking hole 1015, until the end of the limiting block 1018 is elastically locked inside the locking hole 1015, thus securing the rear cover 104 after installation.

[0027] In order to facilitate the adjustment of the limiting block 1018 by rotating the reinforcing component, and conversely, to reinforce the installation after locking and fixing, in this embodiment, preferably, the rotating reinforcing component includes two locking bolts 1014 that are slidably connected at both ends of the closing groove 1011 inside the main housing 101. One side of the limiting block 1018 is provided with an internal threaded hole, and the locking bolts 1014 are rotatably connected to the internal threads of the internal threaded hole. During the locking installation, the locking bolts 1014 can be moved to drive the adjustment of the limiting block 1018, and after the locking installation, the locking bolts 1014 can be rotated to embed into the internal threaded hole for reinforcement.

[0028] The dehumidification mechanism includes desiccant storage dehumidification components disposed on both sides inside the rear cover plate 104. The desiccant storage dehumidification components are provided with inlet and outlet components at their ends, which can fix the ring network box body 100 in a dark and humid location for long-term use. When the inside of the main box 101 becomes damp, the dehumidification mechanism will dehumidify and dry the inside of the main box 101. The dehumidification and drying is convenient and will not cause the inside of the ring network box body 100 to become damp, thus shortening its service life. This improves the convenience of internal drying and dehumidification of the ring network box body 100 during installation and use.

[0029] In order to facilitate the drying and dehumidification of the interior of the ring network box body 100 by means of a desiccant storage dehumidification component, in this embodiment, preferably, the desiccant storage dehumidification component includes storage slots 1041 opened on both sides inside the rear cover plate 104. A breathable mesh 1042 is welded and fixed to one side of the storage slot 1041 on the inner surface of the rear cover plate 104. An appropriate amount of desiccant can be injected into the storage slot 1041, and the moisture inside the ring network box body 100 can be absorbed and dried through the breathable mesh 1042.

[0030] To facilitate the injection and replacement of desiccant into the storage tank 1041 via the inlet / outlet assembly, in this embodiment, preferably, the inlet / outlet assembly includes an inlet 1043 located at the bottom end of the rear cover plate 104. A sealing cap 1044 is rotatably mounted on the end of the inlet 1043, and the inlet 1043 is connected to the internal structure of the storage tank 1041. This facilitates the injection of an appropriate amount of desiccant into the storage tank 1041 for drying and dehumidification through the inlet 1043, and the sealing cap 1044 is rotated to the end of the inlet 1043 for sealing. Conversely, it facilitates the periodic replacement of the desiccant.

[0031] The working principle and usage process of this utility model are as follows: Before using this quick-assembly ring network box structure, first, hold the main box body 101 and slide the clamping plate 1013 until the end of the clamping plate 1013 matches the inner surface of the closing groove 1011. The rear cover plate 104 is then installed inside the closing groove 1011 by clamping the clamping plate 1013 inside the clamping groove 1012. After the rear cover plate 104 is installed, loosen the locking bolt 1014. The elastic block 1017 deforms and springs the limiting block 1018 back to its original position. The locking mechanism engages inside the locking hole 1015 to lock and fix the rear cover plate 104. The locking bolt 1014 is rotated again to embed into the internal threaded hole to reinforce the installation of the limiting block 1018 and the rear cover plate 104. If the ring network box body 100 is damaged due to long-term use after installation, the reverse operation can be performed to quickly disassemble and repair the rear cover plate 104. The installation operation is simple and convenient to achieve rapid assembly without the need for tools to disassemble and assemble multiple screws, which improves the convenience of quick assembly of the rear cover plate 104 when the ring network box body 100 is damaged during installation and use.

[0032] Then, before installing the rear cover plate 104, an appropriate amount of desiccant is injected into the storage tank 1041 through the inlet 1043 of the ring network box body 100. The sealing cover 1044 is then rotated to seal and fix the inlet 1043, thereby fixing the rear cover plate 104 to the rear surface of the main box body 101. When the ring network box body 100 is placed in a dark and humid place for a long time, if moisture occurs inside the ring network box body 100, the desiccant stored in the storage tank 1041 will dry and absorb moisture through the breathable mesh 1042. This makes dehumidification convenient and prevents moisture from occurring inside the ring network box body 100, thus shortening its service life. It also improves the convenience of internal drying and dehumidification of the ring network box body 100 during installation and use, and the desiccant can be replaced periodically.

[0033] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
