Description

Technical Field

[0001] This utility model relates to the field of high voltage switchgear technology, and in particular to an emergency operation structure and switchgear. Background Technology

[0002] To enable emergency operation, existing technology typically incorporates an operating window on the cabinet door of high-voltage switchgear, with a simple door panel hinged to it. This simple door panel can be rotated to open or close the operating window. However, this method of closing the operating window with a simple door panel is of low strength and cannot effectively withstand impacts from internal faults within the high-voltage switchgear. Furthermore, operators operating through the window after opening the simple door panel are vulnerable to the effects of internal faults, potentially leading to injury. Utility Model Content

[0003] The present invention provides an emergency operation structure and switch cabinet, which enables emergency operation of the switch cabinet and improves its ability to resist fault impacts, thereby preventing injury to operators.

[0004] The above-mentioned technical problems are solved by the following technical solutions:

[0005] An emergency operation structure is applied to the cabinet door of a switch cabinet. The cabinet door is provided with a manual switch hole and a slide groove hole, and the inner side of the cabinet door is also provided with a slide rail.

[0006] The emergency operation structure includes:

[0007] A sliding baffle is slidably connected to the slide rail;

[0008] A locking assembly includes a stop pin and a locking sleeve slidably sleeved on the stop pin. The stop pin is slidably disposed in the slide groove and fixedly connected to the slide baffle. The locking sleeve can be inserted into the slide groove at least when the slide baffle blocks the manual switch hole, so as to restrict the sliding of the stop pin.

[0009] The sliding baffle slides along the slide rail to a first position, where the stop pin abuts against the first end of the slide groove hole, and the sliding baffle blocks the manual switch hole; or, the sliding baffle slides along the slide rail to a second position, where the stop pin abuts against the second end of the slide groove hole, and the sliding baffle moves away from the manual switch hole.

[0010] In one embodiment, the slide hole is provided with a limiting structure at least at the first end, and the locking sleeve can be inserted into the limiting structure to limit the stop pin to the first position.

[0011] In one embodiment, the limiting structure includes a limiting hole; the outer diameter of the locking sleeve and the inner diameter of the limiting hole are both larger than the width of the sliding groove hole. When the locking sleeve is inserted into the limiting hole, the stop pin is limited to the first position by the locking sleeve. When the locking sleeve is separated from the limiting hole, the limiting hole releases the restriction on the locking sleeve, allowing the stop pin to slide along the sliding groove hole.

[0012] In one embodiment, the limiting structure includes a snap-fit ​​groove;

[0013] The locking sleeve has a snap-fit ​​protrusion at one end facing the sliding baffle. When the snap-fit ​​protrusion is inserted into the snap-fit ​​groove, the stop pin is limited to the first position by the locking sleeve. When the snap-fit ​​protrusion is separated from the snap-fit ​​groove, the snap-fit ​​groove releases the restriction on the locking sleeve, so that the stop pin can slide along the sliding hole.

[0014] In one embodiment, the center line of the snap-fit ​​groove along its own length is perpendicular to the center line of the slide hole along its own length.

[0015] In one embodiment, the locking assembly further includes a padlock;

[0016] The stop pin is provided with a locking hole that extends radially through it. When the locking sleeve is inserted into the sliding hole for locking, the locking hole is exposed. The padlock is disposed in the locking hole to prevent the locking sleeve from unlocking from the sliding hole.

[0017] In one embodiment, the inner side of the cabinet door is provided with two pads and two track plates. The two pads are spaced apart and connected to the cabinet door, and the two track plates are respectively disposed on the two pads so that the track plates and the cabinet door form the slide rail.

[0018] In one embodiment, the distance between the track plate and the cabinet door is greater than the thickness of the sliding baffle, and the difference between the distance between the track plate and the cabinet door and the thickness of the sliding baffle does not exceed 0.5 mm.

[0019] In one embodiment, the cabinet door is also provided with an observation window;

[0020] The sliding baffle is provided with a clearance notch to avoid the observation window.

[0021] In one embodiment, the manual switch hole includes a manual closing hole, a manual opening hole, and a manual energy storage operation hole;

[0022] The sliding baffle includes a horizontal plate for blocking the manual closing hole and the manual opening hole, and a vertical plate for blocking the manual energy storage operation hole.

[0023] A switch cabinet, including a cabinet door and an emergency operation structure as described in any of the above embodiments mounted on the cabinet door.

[0024] The beneficial effects of this utility model are as follows:

[0025] The emergency operation structure provided by this utility model uses a sliding baffle that is slidably connected to the cabinet door, allowing the sliding baffle to block the manual switch hole. Compared with the simple door panel in the prior art, this improves the ability to resist the impact of faults from inside the switch cabinet. When an emergency operation of the switch cabinet is required, the sliding baffle can slide from a first position (the first position is where the sliding baffle blocks the manual switch hole) to a second position (the second position is where the sliding baffle is separated from the manual switch hole), so that the sliding baffle is separated from the manual switch hole, making it easier for the operator to operate the switch cabinet. When the sliding baffle is at least in the first position, the locking sleeve can also be inserted into the slide groove hole to fix the sliding baffle in the first position, that is, to lock the sliding baffle and the cabinet door, thereby restricting the sliding of the sliding baffle and preventing accidental operation of the switch cabinet.

[0042] Example 1

[0043] This utility model embodiment provides an emergency operation structure for use on the cabinet door 100 of a switch cabinet. The cabinet door 100 is provided with a manual switch hole 101 and a sliding groove hole 102. The emergency operation structure can block the manual switch hole 101 and separate from the manual switch hole 101. When the switch cabinet needs to be operated in an emergency, the emergency operation structure can separate from the manual switch hole 101 to expose the manual operation switch inside the switch cabinet for the convenience of the operator.

[0044] like Figures 1-5 As shown, the emergency operation structure includes a sliding baffle 1 and a locking assembly 2. The sliding baffle 1 is slidably connected to the slide rail 13, allowing it to slide and switch between a first position and a second position. When the sliding baffle 1 is in the first position, it blocks the manual switch hole 101 to ensure the airtightness of the switch cabinet; in this state, there is no need to operate the operating switch. When the sliding baffle 1 is in the second position, it separates from the manual switch hole 101, exposing the manual operating switch. This is an emergency state, and the operator can operate the manual operating switch through the manual switch hole 101.

[0045] The locking assembly 2 includes a stop pin 21 and a locking sleeve 22. The stop pin 21 is slidably disposed within the slide groove 102 and fixedly connected to the sliding baffle 1. When the sliding baffle 1 slides between a first position and a second position, the stop pin 21 can abut against the first end and the second end of the slide groove 102 respectively, so that the sliding baffle 1 is limited to the first position and the second position respectively. The locking sleeve 22 is slidably sleeved on the stop pin 21. When the sliding baffle 1 slides to the first position or the second position respectively, the locking sleeve 22 can be inserted into the slide groove 102 to restrict the sliding of the stop pin 21, so that the sliding baffle 1 is limited to the first position or the second position, thereby locking the sliding baffle 1 with the cabinet door 100. Of course, the locking sleeve 22 is inserted into the slide groove 102 at least in the first position to lock the cabinet door 100 and the sliding baffle 1, which is sufficient to prevent anyone other than the operator from operating the switch cabinet.

[0046] The emergency operation structure is slidably connected to the cabinet door 100 via a sliding baffle 1, which allows the sliding baffle 1 to block the manual switch hole 101. Compared with the simple door panel in the prior art, this improves the ability to resist the impact of faults from inside the switch cabinet. When an emergency operation of the switch cabinet is required, the sliding baffle 1 can slide from the first position to the second position, so that the sliding baffle 1 is separated from the manual switch hole 101, so that the operator can operate the switch cabinet. When the sliding baffle 1 is at least in the first position, the locking sleeve 22 can also be inserted into the slide groove hole 102 to fix the sliding baffle 1 in the first position, that is, to lock the sliding baffle 1 and the cabinet door 100, thereby restricting the sliding of the sliding baffle 1 and preventing accidental operation of the switch cabinet.

[0047] In this embodiment, the manual operation switch includes a manual closing switch, a manual opening switch, and a manual energy storage switch; the manual switch hole 101 includes a manual closing hole 1011, a manual opening hole 1012, and a manual energy storage operation hole 1013. The manual closing hole 1011 and the manual opening hole 1012 are both round holes, and the manual energy storage operation hole 1013 is an elongated hole extending along the height direction of the cabinet door 100. The manual closing hole 1011 is aligned with the manual closing switch, the manual opening hole 1012 is aligned with the manual opening switch, and the manual energy storage operation hole 1013 is aligned with the manual energy storage switch, so that when the sliding baffle 1 is switched to the second position, and the sliding baffle 1 is separated from the manual opening hole 1012, the manual closing hole 1011, and the manual energy storage operation hole 1013, the manual closing switch, the manual opening switch, and the manual energy storage switch can be exposed to facilitate operation by the operator.

[0048] Furthermore, such as Figure 3 and combined Figure 2 As shown, the locking assembly 2 also includes a padlock 23; the stop pin 21 is provided with a locking hole 211 that extends radially through it. When the sliding baffle 1 is in the first position or the second position respectively, the locking sleeve 22 can be inserted and locked with the sliding groove hole 102, so that the locking hole 211 can be exposed and the padlock 23 can be installed in the locking hole 211 to restrict the locking sleeve 22 from unlocking the sliding groove hole 102, so as to prevent operation by anyone other than the operator.

[0049] In this embodiment, the lock hole 211 is set as a circular hole with a diameter of φ8mm.

[0050] Optionally, both the first and second ends of the sliding hole 102 are provided with a limiting structure (of course, the second end of the sliding hole 102 may not be provided with a limiting structure, because when the sliding baffle 1 is in the second position, it is in a separated state from the manual switch hole 101, and locking is not required when the sliding baffle 1 is separated from the manual switch hole 101). The locking sleeve 22 can be inserted into the limiting structure so that the stop pin 21 is limited to the first position.

[0051] In one embodiment, the limiting structure includes a limiting hole 1021. When the sliding baffle 1 is in the first position and the second position respectively, the locking sleeve 22 slides toward the sliding baffle 1 and inserts into the limiting hole 1021, and the locking sleeve 22 can abut against the sliding baffle 1 to limit the movement. The limiting hole 1021, through its insertion and engagement with the locking sleeve 22, restricts the sliding of the locking assembly 2 within the slide groove hole 102. The stop shaft is fixedly connected to the sliding baffle 1, so that the sliding baffle 1 can be limited to the first position or the second position. This structure is simple in design and easy to operate. If unlocking is required, the locking sleeve 22 is moved away from the sliding baffle 1 to separate the locking sleeve 22 from the limiting hole 1021, and the locking assembly 2 can then slide along the slide groove hole 102, realizing the switching of the sliding baffle 1 between the first position and the second position. It is understandable that the outer diameter of the locking sleeve 22 and the inner diameter of the limiting hole 1021 are both larger than the width of the sliding hole 102, so that when the locking sleeve 22 is inserted into the limiting hole 1021, the locking sleeve 22 cannot slide in the sliding hole 102.

[0052] Of course, it is understandable that when the locking sleeve 22 slides toward the cabinet door 100, the lock hole 211 can be exposed.

[0053] Optionally, such as Figure 5 As shown, the inner side of the cabinet door 100 is provided with two pads 131 and two track plates 132. The two pads 131 are spaced apart along the height direction of the cabinet door 100 and are fixedly connected to the cabinet door 100. The two track plates 132 are respectively fixedly installed on the two pads 131 so that a slide rail 13 is formed between the track plate 132 and the cabinet door 100. The sliding baffle 1 is slidably installed in the two slide rails 13 at both ends along the height direction of the cabinet door 100 so as to realize the sliding connection between the sliding baffle 1 and the cabinet door 100.

[0054] To ensure that the protection level of the switchgear can reach IP4X, the distance between the track plate 132 and the cabinet door 100 is greater than the thickness of the sliding baffle 1 but does not exceed 0.5mm, that is, the gap between the track plate 132 and the cabinet door 100 does not exceed 0.5mm.

[0055] For easy identification, the sliding baffle 1 is marked with labels at the positions corresponding to the manual closing switch, manual opening switch, and manual energy storage switch. When the sliding baffle 1 is in the first position, the three labels are aligned with the manual closing hole 1011, the manual opening hole 1012, and the manual energy storage operation hole 1013, respectively.

[0056] Optionally, refer to Figure 1 and Figure 4As shown, the cabinet door 100 is also provided with an observation window 103, and a transparent glass 104 is installed at the observation window 103; the sliding baffle 1 is provided with a clearance notch 14 to avoid the observation window 103. When the sliding baffle 1 is in the first position, the situation inside the switch cabinet can be observed through the transparent glass 104.

[0057] Furthermore, the sliding baffle 1 is configured as U-shaped, U-shaped, or inverted L-shaped. The sliding baffle 1 includes a horizontal plate 11 for blocking the manual closing hole 1011 and the manual opening hole 1012, and a vertical plate 12 for blocking the manual energy storage operation hole 1013. In this structure, by providing an avoidance notch 14 in the sliding baffle 1, when the sliding baffle 1 is in the first position, the avoidance notch 14 can avoid the observation window 103, the horizontal plate 11 can block the manual closing hole 1011 and the manual opening hole 1012, and the vertical plate 12 can block the manual energy storage operation hole 1013.

[0058] Optionally, the transparent glass 104 may be made of explosion-proof material to improve the strength of the transparent glass 104.

[0059] This utility model embodiment also provides a switch cabinet, including a cabinet body, a cabinet door 100 disposed on the cabinet body, and an emergency operation structure installed on the cabinet door 100. By setting an emergency operation structure on the cabinet door 100, emergency operation can be performed in an emergency, and safety is improved.

[0060] Example 2

[0061] This utility model provides an emergency operation structure, which is basically the same as that of Embodiment 1. For convenience, only the differences are described here.

[0062] like Figures 6-8 As shown, the limiting structure includes a snap-fit ​​groove 1022, the center line of which along its length does not coincide with the center line of the sliding hole 102 along its length. The locking sleeve 22 has two snap-fit ​​protrusions 221 at one end facing the sliding baffle 1. When the sliding baffle 1 is in the first and second positions respectively, the locking sleeve 22 moves towards the sliding baffle 1, causing the snap-fit ​​protrusions 221 to engage with the snap-fit ​​groove 1022, thus restricting the locking assembly 2 from sliding within the sliding hole 102, thereby limiting the sliding baffle 1 to the first or second position. It is understood that the sliding baffle 1 has a clearance hole to avoid the snap-fit ​​protrusions 221. When the snap-fit ​​protrusions 221 engage with the snap-fit ​​groove 1022, the locking sleeve 22 abuts against the cabinet door 100 for limitation, and the snap-fit ​​protrusions 221 can extend into the clearance hole.

[0063] Furthermore, the center line of the snap-fit ​​groove 1022 along its own length is perpendicular to the center line of the sliding hole 102 along its own length. This structure makes the snap-fit ​​boss 221 and the snap-fit ​​groove 1022 snap-fit ​​firmly, making the design and processing more convenient and further improving the snap-fit ​​stability.

[0064] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0065] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
