Description

Technical Field

[0001] This utility model relates to the technical field of ring network switchgear, specifically to an interlocking device between the incoming line cabinet and the metering cabinet. Background Technology

[0002] Existing incoming line cabinets often have a metering cabinet on the side, containing a meter used to measure the electrical energy of the incoming line cabinet. However, the metering cabinet contains both secondary output terminals and exposed 10kV high-voltage components. Therefore, the cabinet door must not be opened when the incoming line cabinet is energized to prevent injury to personnel.

[0003] A high-voltage metering cabinet hard interlocking device includes an inlet line interlocking pin, an inlet line spring, an inlet line interlocking box, a metering interlocking pin, a metering spring, a metering interlocking box, an operating pin, a baffle, and a positioning plate. The left end of the inlet line interlocking pin protrudes from the inlet line interlocking box, and the right end of the inlet line interlocking pin protrudes sequentially from the right side wall of the inlet line interlocking box and the cabinet partition plate. The inlet line spring is engaged between the left side inner wall and the top plate of the inlet line interlocking box. The front and rear ends of the top plate are respectively close to the front and rear walls of the inlet line interlocking box. The inlet line interlocking pin can move linearly left and right. The metering interlocking pin has a groove and a top plate at the middle and front ends, respectively, allowing the metering interlocking pin to move linearly back and forth. The positioning plate is fixed to the left side inner wall of the inlet cabinet. The front end of the operating pin passes through the positioning plate, and its rear end is hinged to the left end of the inner wall of the inlet cabinet door. The operating pin can move linearly back and forth. The right end of the baffle is hinged to the left edge of the metering cabinet door. However, the locking device restricts the incoming cabinet door to only move back and forth, limiting its movement space. In the vertical direction, the incoming cabinet door cannot move up and down, thus separating the incoming cabinet door from the incoming cabinet. Utility Model Content

[0004] The purpose of this invention is to provide an interlocking device between the incoming line cabinet and the metering cabinet that does not restrict the vertical movement of the lower cabinet door of the incoming line cabinet.

[0005] To achieve the first objective of this utility model, the present utility model provides an interlocking device for an incoming line cabinet and a metering cabinet. The metering cabinet is located on the first side of the incoming line cabinet, and its lower door panel is located on the first side of the lower door of the incoming line cabinet. The interlocking device includes a first limiting mechanism and a second limiting mechanism. The first limiting mechanism includes a first support frame, a first limiting shaft, and a first elastic component. The first limiting shaft moves vertically on the first support frame, passes through the first side panel of the incoming line cabinet and the second side panel of the metering cabinet, and its first end abuts against a first limiting block of the lower door of the incoming line cabinet. The first limiting block is located above the first end of the first limiting shaft, and the second end of the first limiting shaft abuts against the lower door of the metering cabinet. The second limiting block of the door panel is engaged; the first end of the first elastic component abuts against the first limiting shaft, and the second end of the first elastic component abuts against the first support frame; the second limiting mechanism includes a second support frame, a first movable shaft, a first limiting plate, and a second elastic component. The first movable shaft moves along the opening direction of the inlet cabinet on the second support frame, and the first movable shaft drives the first limiting plate to move. The first movable shaft abuts against the third limiting block of the lower cabinet door. The first limiting plate passes through the first side plate and the second side plate, and the first limiting plate abuts against the fourth limiting block of the lower door panel; the second elastic component is sleeved outside the first movable shaft, the first end of the second elastic component abuts against the first limiting plate, and the second end of the second elastic component abuts against the second support frame.

[0006] As can be seen from the above scheme, when the incoming line cabinet is de-energized and can be opened, the lower cabinet door is opened first. After the first limiting shaft is no longer restricted by the first limiting block, it moves upwards along the vertical direction under the elastic force of the first elastic component. At this time, the first limiting shaft is not stuck on the second limiting block of the metering cabinet. Simultaneously, the first movable shaft is no longer restricted by the third limiting block and moves outwards along the opening direction of the incoming line cabinet under the elastic force of the second elastic component. At this time, the first limiting plate also moves outwards. Since the lower door panel of the metering cabinet is not restricted by the second and fourth limiting blocks, the metering cabinet door is open. When the lower cabinet door needs to be closed, the lower door panel of the metering cabinet must be closed first. At this time, the first limiting plate abuts against the fourth limiting block, and the second elastic component is compressed, allowing the lower cabinet door to close. After the lower cabinet door is closed, the first limiting block is above the first limiting shaft, the first elastic component is compressed, and the first limiting shaft is locked against the second limiting block, preventing the lower door panel from opening. The first and second limiting mechanisms allow the lower cabinet door to move vertically without being affected by the limiting components.

[0007] In a further embodiment, the first limiting mechanism also includes a second movable shaft, which is vertically and fixedly connected to the first limiting shaft. The second movable shaft moves on the first support frame, and the first limiting shaft drives the second movable shaft to move.

[0008] Therefore, the first limiting axis is restricted to move on the first support frame by the second movable axis.

[0009] In a further embodiment, the first elastic component is fitted over the second movable shaft.

[0010] It can be seen that the second movable axis makes the first elastic component move more stably in the vertical direction.

[0011] In a further embodiment, the second limiting block has an upwardly oriented first groove, and the second end of the first limiting shaft passes through the first groove.

[0012] Therefore, the upward-facing groove ensures that the lower cabinet door can only be closed after the lower cabinet door is closed. If the lower cabinet door is closed first, the lower cabinet door cannot be closed.

[0013] In a further embodiment, the first side plate is provided with a first elongated hole, and the second side plate is provided with a second elongated hole. The first elongated hole and the second elongated hole are provided correspondingly, and the length direction of the first elongated hole and the second elongated hole is vertical. The first limiting shaft passes through the first elongated hole and the second elongated hole.

[0014] Therefore, the distance the first limiting shaft can move can be limited by the first elongated hole and the second elongated hole.

[0015] In a further embodiment, the first side plate is provided with a third elongated hole, and the second side plate is provided with a fourth elongated hole. The third and fourth elongated holes are provided in a corresponding manner, and the length direction of the third and fourth elongated holes is the opening direction of the incoming line cabinet. The first limiting plate passes through the first and second elongated holes.

[0016] It can be seen that the distance the first limiting plate moves is limited by the third and fourth elongated holes.

[0017] In a further embodiment, the first support frame is provided with a fifth elongated hole, through which the first limiting shaft passes, and the length direction of the fifth elongated hole is vertical.

[0018] It can be seen that the first limiting shaft can move on the first support frame through the fifth elongated hole.

[0019] In a further embodiment, the second support frame is provided with a sixth elongated hole, through which the first limiting plate passes, and the length of the sixth elongated hole is in the direction of the opening of the incoming line cabinet.

[0020] It can be seen that the first limiting plate can move on the second support frame through the fifth elongated hole. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] The interlocking device between the incoming line cabinet and the metering cabinet provided by this utility model, through the first and second limiting mechanisms, ensures that when the lower cabinet door of the incoming line cabinet is closed, the lower door panel of the metering cabinet cannot be opened. Before the lower cabinet door of the incoming line cabinet can be closed, the lower door panel of the metering cabinet must be closed first. The first and second limiting mechanisms also allow the lower cabinet door 11 to move vertically without being affected by the limiting components.

[0037] See Figure 1 In this embodiment, the interlocking device between the incoming line cabinet and the metering cabinet includes a metering cabinet 2 and an incoming line cabinet 1. The metering cabinet 2 is located on the first side of the incoming line cabinet 1, and the lower door panel 21 of the metering cabinet 2 is located on the first side of the lower cabinet door 11 of the incoming line cabinet 1.

[0038] See Figures 2 to 9 The interlocking device includes a first limiting mechanism and a second limiting mechanism. The first limiting mechanism includes a first support frame 131, a first limiting shaft 1321, and a first elastic component 134. The first limiting shaft 1321 moves vertically on the first support frame 131. The first limiting mechanism also includes a second movable shaft 1322, which is vertically fixedly connected to the first limiting shaft 1321. The second movable shaft 1322 moves on the first support frame 131, and the first limiting shaft 1321 drives the second movable shaft 1322 to move.

[0039] The first limiting shaft 1321 passes through the first side plate 12 of the incoming line cabinet 1 and the second side plate 22 of the metering cabinet 2. Specifically, the first side plate 12 is provided with a first elongated hole 121, and the second side plate 22 is provided with a second elongated hole 221. The first elongated hole 121 and the second elongated hole 221 are correspondingly provided, and the length direction of the first elongated hole 121 and the second elongated hole 221 is vertical. The first limiting shaft 1321 passes through the first elongated hole 121 and the second elongated hole 221.

[0040] The first end of the first limiting shaft 1321 abuts against the first limiting block 111 of the lower cabinet door 11 of the incoming line cabinet. The first limiting block 111 is above the first end of the first limiting shaft 1321. The second end of the first limiting shaft 1321 engages with the second limiting block 211 of the lower door panel 21 of the metering cabinet 2. Specifically, the second limiting block 211 has an upwardly oriented first groove 2111, through which the second end of the first limiting shaft 1321 passes.

[0041] The first elastic component 134 is sleeved outside the second movable shaft 1322. The first end of the first elastic component 134 abuts against the first limiting shaft 1321, and the second end of the first elastic component 134 abuts against the first support frame 131.

[0042] See Figures 2 to 12The second limiting mechanism includes a second support frame 141, a first movable shaft 142, a first limiting plate 143, and a second elastic component 144. The first movable shaft 142 moves along the opening direction of the cable tray 1 on the second support frame 141, and drives the first limiting plate 143 to move. The first movable shaft 142 abuts against the third limiting block 112 of the lower cabinet door 11. A second groove 1421 is provided on the first movable shaft 142, and the first limiting plate 143 is disposed on the second groove 1421.

[0043] See Figure 13 and Figure 14 The first limiting plate 143 passes through the first side plate 12 and the second side plate 22. Specifically, the first side plate 12 is provided with a third elongated hole 122, and the second side plate 22 is provided with a fourth elongated hole 222. The third elongated hole 122 and the fourth elongated hole 222 are provided correspondingly. The length direction of the third elongated hole 122 and the fourth elongated hole 222 is the opening direction of the incoming line cabinet 1. The first limiting plate 143 passes through the first elongated hole 122 and the second elongated hole 222.

[0044] The first limiting plate 143 abuts against the fourth limiting block 211 of the lower door panel 21. The second elastic member 144 is sleeved outside the first movable shaft 142, the first end of the second elastic member 144 abuts against the first limiting plate 143, and the second end of the second elastic member 144 abuts against the second support frame 141.

[0045] When the incoming line cabinet 1 is de-energized and can be opened, the lower cabinet door 11 is opened first. After the first limiting shaft 1321 is no longer limited by the first limiting block 111, it moves upward along the vertical direction under the elastic force of the first elastic component 134. At this time, the first limiting shaft 1321 is not stuck on the second limiting block 211 of the metering cabinet 2. At the same time as the lower cabinet door 11 is opened, the first movable shaft 142 is no longer limited by the third limiting block 112. Under the elastic force of the second elastic component 144, it moves outward along the opening direction of the incoming line cabinet 1. At this time, the first limiting plate 143 also moves outward. Since the lower door panel 21 of the metering cabinet 2 is no longer limited by the second limiting block 211 and the fourth limiting block 212, the lower door panel 21 of the metering cabinet 2 is opened. When the lower cabinet door 11 is to be closed, the lower door panel 21 of the metering cabinet 2 must first be closed. At this time, the first limiting plate 143 abuts against the fourth limiting block 212, and the second elastic component 144 is compressed. The lower cabinet door 11 can then be closed. After the lower cabinet door 11 is closed, the first limiting block 111 is above the first limiting shaft 1321, the first elastic component 134 is compressed, and the first limiting shaft 1321 engages with the second limiting block 211, preventing the lower door panel 21 from opening. Through the setting of the first and second limiting mechanisms, the lower cabinet door 11 can move vertically without being affected by the limiting components.

[0046] The above is only a preferred embodiment of the present utility model, but the design concept of the utility model is not limited thereto. Without departing from the concept of the present utility model, more other equivalent embodiments may be included. Those skilled in the art can make various obvious changes, readjustments and substitutions without departing from the protection scope of the present utility model.
