Technical Field
[0001] The utility model relates to the technical field of power distribution, in particular to a locking type primary and secondary fusion ring network box. Background Art
[0002] A locking, integrated primary and secondary ring main unit (RME) is a key component in distribution network systems. It integrates primary and secondary equipment, assuming the functions of power distribution, fault isolation, and intelligent monitoring. With the increasing automation of distribution networks, the sealing, safety protection, and intelligent status monitoring capabilities of the RMU have become key factors affecting the reliable operation of equipment.
[0003] Most ring main units (RMBs) use manual knobs, latches, or conventional electronic locks to lock the door. These locks lack mechanical limits or status feedback for their final position. If the operator fails to control the lock to the set travel, the door can easily become ajar, causing seal failure and potential safety hazards. Therefore, it is necessary to directly track the movement of the lock to accurately determine whether it has reached the preset locking position, thereby fundamentally resolving the industry pain point of "closed but not locked."

[0033] A locking member is provided on the rear end surface of the right door 12, and a matching locking block 21 is fixedly provided on the rear end surface of the left door 12; the locking member includes a driving block 61, a locking extension block 43 linked to the driving block 61, and a driving member that drives the driving block 61 to move; the driving block 61 can stay in the first position or the second position under the drive of the driving member. When the driving block 61 stays in the first position, the locking extension block 43 will extend into the matching locking block 21, and the interference between the two keeps the two doors 12 in the closed state; when the driving block 61 stays in the second position, the locking extension block 43 separates from the matching locking block 21, so that the two doors 12 are released from the closed state;
[0034] The locking member further includes a position detection component capable of detecting whether the driving block 61 stays at the first position or the second position.
[0035] Specifically, the driving component includes a shell body 31 fixed to the rear end surface of the corresponding box door 12. The shell body 31 is composed of a front plate and a bottom plate 311. A plurality of bearing columns 312 are provided on the bottom plate 311, so that a mounting cavity can be formed between the front plate and the bottom plate 311; a hollow mounting cavity is formed inside the shell body 31, and an arc-shaped groove 32 is provided on the side of the bottom plate 311 facing the mounting cavity, and an inner movable block 33 is provided in the arc-shaped groove 32; a vertical through-hole 34 is provided in the bottom plate 311, and a driving shaft 35 is passed through the through-hole 34.

An infrared emitting tube is fixedly arranged in one of the detection arms 72, and an infrared receiving tube 74 is fixedly arranged in the other detection arm 72. The infrared emitting tube and the infrared receiving tube 74 are both arranged facing the spacer 73.

In this embodiment, the single-chip microcomputer adopts STM8, the touch screen 92 adopts GP3000 touch screen 92, the infrared emitting tube and infrared receiving tube 74 adopt IR928-6C and PT928-6C, and the communication module adopts ESP8266.
[0046] A charging port 93 for charging the lithium battery is also provided at the front end of the control panel 91 .
[0047] The working principle of this embodiment is:
[0048] 1. After closing the two doors 12, the "lock" signal is sent to the single-chip microcomputer through the control of the touch screen 92 or the remote terminal. The single-chip microcomputer controls the action of the drive motor 83, and the drive motor 83 drives the drive block 36 to rotate. After the drive block 36 rotates, it drives the inner movable block 33 to move from bottom to top along the arc groove 32. After the inner movable block 33 moves, it causes the driving block 61 to move from bottom to top along the second track axis 52; until the positioning protrusion 75 in the upper position detection sub-component is against the positioning cross plate 82, at this time, the driving block 61 stays in the first position; at the same time, the locking extension block 43 extends into the insertion groove 211 of the matching locking block 21, and the locking purpose is achieved based on the contact between the locking extension block 43 and the groove wall of the insertion groove 211.
[0049] 2. When the two doors 12 need to be opened, the "unlock" signal is sent to the single-chip microcomputer through the control of the touch screen 92 or the remote terminal. The single-chip microcomputer controls the drive motor 83 to operate. The drive motor 83 will drive the drive block 36 to rotate. After the drive block 36 rotates, it will drive the inner movable block 33 to move from top to bottom along the arc groove 32 until the positioning protrusion 75 in the position detection sub-component below is against the positioning cross plate 82. At this time, the driving block 61 stays in the second position; at the same time, the locking extension block 43 is separated from the extension groove 211, and the operator can freely open / close the door 12.
[0050] 3. After the MCU receives the "unlock" signal, it will periodically send an "unlocked" signal to the remote terminal and touch screen through the communication module at regular intervals to serve as a reminder; until the MCU receives the "lock" signal or is manually canceled.
[0051] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
