Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, specifically a new type of switch cabinet that is easy to maintain. Background Technology

[0002] Switchgear is an indispensable and important piece of equipment in a power system. Through components such as circuit breakers, disconnect switches, fuses, instrument transformers, relays, busbars, and control and protection devices, it realizes the distribution of electrical energy, protection of circuits, control of operation, and detection of faults.

[0003] Switchgear typically has mounting plates inside for installing components. There are multiple mounting plates on the top and bottom for installing components with different functions. In the current technology, the mounting plates are installed horizontally inside the switchgear, and their positions are fixed. When it is necessary to repair or replace the components, the large number of components, the complex connection lines between them, and the small internal space of the switchgear make it difficult to repair or replace the components, which affects the normal use of the switchgear. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a new type of switch cabinet that is convenient for maintenance.

[0005] The technical solution of this utility model is as follows:

[0006] A novel switchgear for easy maintenance includes a switchgear body. The width of the switchgear body extends from its front to its rear. Symmetrical support frames are provided on both sides of the switchgear body along its length. The support frames are fixedly connected to the inner wall of the switchgear body and are vertically arranged. A vertically arranged mounting plate is provided inside the switchgear body. Both sides of the mounting plate are connected to the two support frames, and the position of the mounting plate is adjustable along the width of the switchgear body.

[0007] The support frame has a through sliding elongated hole along the vertical direction. The length direction of the sliding elongated hole is consistent with the length direction of the support frame. Both sides of the mounting plate are slidably connected to the corresponding sliding elongated hole through sliding rods. The sliding rods are equipped with snap-fit ​​units, and the sliding rods are detachably connected to the support frame through the snap-fit ​​units.

[0008] The mounting plate is installed inside the switchgear body via support frames on both sides. The mounting plate is used to install various components such as circuit breakers, disconnect switches, fuses, transformers, and relays. The two sides of the mounting plate can be slidably connected to the corresponding support frames, allowing the mounting plate and the components on it to move along its width within the switchgear body, i.e., to move back and forth. This facilitates the movement of the mounting plate outward by a certain distance during maintenance or component replacement. The mounting plate can be fixedly connected to the support frame during or after maintenance via sliding rods and snap-fit ​​units.

[0009] The specific structure of the aforementioned support frame is as follows: the support frame includes an upper rod and a lower rod arranged in parallel. The ends of the upper rod and the lower rod on the same side are connected by vertical rods. The two vertical rods, together with the upper rod and the lower rod, form a frame structure. The two vertical rods are fixedly connected to the inner wall of the switch cabinet body. The upper rod and the lower rod are provided with corresponding sliding joint elongated holes along their length direction. The sliding joint rod passes through the sliding joint elongated holes of the upper rod and the lower rod on the same side.

[0010] The structure of the sliding elongated hole is as follows: the sliding elongated hole includes an elongated hole and multiple snap-fit ​​holes connected to it. The snap-fit ​​holes are arranged at equal intervals along the length of the elongated hole, and a snap-fit ​​groove adapted to the snap-fit ​​unit is provided on one side of the snap-fit ​​hole.

[0011] The snap-fit ​​hole and the elongated hole are designed such that the snap-fit ​​hole is rectangular and perpendicular to the elongated hole. The length of the snap-fit ​​hole is greater than the width of the elongated hole. The two ends of the snap-fit ​​hole are symmetrically positioned on both sides of the width direction of the elongated hole. The length direction of the snap-fit ​​hole is consistent with the length direction of the switch cabinet body. This allows for fine-tuning of the position of various components along the length direction of the switch cabinet body when installing them on the mounting plate. It also allows the mounting plate to move along the width direction of the switch cabinet body, which facilitates disassembly and maintenance and allows for reasonable arrangement of various components within the switch cabinet body according to their available space.

[0012] The snap-fit ​​unit consists of a snap-fit ​​ball and an elastic element. A mounting groove for the snap-fit ​​ball is provided on the side of the sliding rod near the elongated hole. The snap-fit ​​ball is connected to the mounting groove via the elastic element, and the snap-fit ​​ball protrudes outward from the outside of the mounting groove. When the sliding rod is moved into the corresponding snap-fit ​​hole, the snap-fit ​​ball snaps into the snap-fit ​​groove, connecting the mounting plate to the support frame. External force moves the sliding rod outward, allowing the snap-fit ​​ball to disengage from the snap-fit ​​groove. The sliding rod moves from the snap-fit ​​hole into the elongated hole, allowing adjustment of the mounting plate's position along the width of the switchgear body. The width of the sliding rod along the width of the switchgear body matches the width of the snap-fit ​​hole, preventing wobbling when the sliding rod moves within the snap-fit ​​hole and avoiding any interference with the snap-fit ​​ball's engagement in the snap-fit ​​groove.

[0013] To facilitate the disengagement of the snap-fit ​​ball from the snap-fit ​​groove under operator operation, the portion of the snap-fit ​​ball protruding outside the mounting groove is set to be no more than half its volume. This allows the snap-fit ​​ball to be pressed inward against the elastic element under the action of external force along the length of the switchgear body, causing the snap-fit ​​ball to move into the mounting groove and disengage from the snap-fit ​​groove as the sliding rod moves, thus preventing the snap-fit ​​ball from getting stuck in the snap-fit ​​groove and being unable to move out.

[0014] To facilitate the movement of the mounting plate along its length or width within the switchgear body, a push-pull rod is inserted into the sliding rod. The length of the push-pull rod is less than the width of the switchgear body, making it easy to move the position of the mounting plate using the push-pull rod.

[0015] The aforementioned push-pull rod is positioned such that a cabinet door is located on the front side of the switch cabinet body, and a connecting plate is located on the side of the switch cabinet body near the cabinet door. The connecting plate is vertically positioned and has multiple overlapping holes along its length. One end of the push-pull rod extends outward through the overlapping holes.

[0016] To facilitate the manufacturing of the snap-fit ​​groove on the support frame, the snap-fit ​​groove is a semi-circular groove with its length direction being vertical and both the top and bottom ends being open.

[0017] The beneficial effects of this utility model are as follows:

[0018] The mounting plate is set on two symmetrically arranged support frames and can move along the length or width of the switch cabinet body on the support frames. This facilitates the installation or removal of components on the mounting plate. When installing or removing components, the mounting plate can be moved towards the front, back or left and right sides of the switch cabinet body. It can be adapted to the size or model of each component and arranged in the switch cabinet body, making reasonable use of the internal space of the switch cabinet body. When installing or removing components, the mounting plate and the components on it can be moved outward by a certain distance, reducing the phenomenon of maintenance difficulties due to the small internal space of the switch cabinet body.

[0019] Move the sliding rod to one side into the snap-fit ​​hole so that the snap-fit ​​ball snaps into the snap-fit ​​groove, thus connecting the mounting plate and the support frame. This prevents the mounting plate from moving when installing or removing components, facilitating installation, disassembly, and maintenance. Attached Figure Description

[0030] See Figure 1 , Figure 2 and Figure 3 As shown, a novel switchgear for easy maintenance includes a switchgear body 1. The width of the switchgear body 1 extends from its front to its rear side 102. Symmetrical support frames 2 are arranged on both sides of the switchgear body 1 along its length. The support frames 2 are fixedly connected to the inner wall of the switchgear body 1 and are vertically oriented. A vertically oriented mounting plate 9 is provided inside the switchgear body 1. Both sides of the mounting plate 9 are connected to two support frames 2, and the position of the mounting plate 9 is adjustable along the width of the switchgear body 1. In this embodiment, multiple sets of mounting plates 9 and their corresponding support frames 2 can be provided and distributed at equal intervals along the interior of the switchgear body 1.

[0031] The support frame 2 has a through sliding elongated hole 3 in the vertical direction. The length direction of the sliding elongated hole 3 is consistent with the length direction of the support frame 2. Both sides of the mounting plate 9 are slidably connected to the corresponding sliding elongated hole 3 by sliding rods 6. The sliding rods 6 are provided with snap-fit ​​units, and the sliding rods 6 are detachably connected to the support frame 2 through the snap-fit ​​units.

[0032] See Figure 3 , Figure 4 and Figure 7 As shown, the support frame 2 includes an upper rod 201 and a lower rod 202 arranged parallel to each other. The ends of the upper rod 201 and the lower rod 202 on the same side are connected by vertical rods 203. The two vertical rods 203 form a frame structure with the upper rod 201 and the lower rod 202. The two vertical rods 203 are fixedly connected to the inner wall of the switch cabinet body 1. The upper rod 201 and the lower rod 202 are provided with corresponding sliding joint holes 3 along their length direction. The sliding joint rod 6 passes through the sliding joint holes 3 of the upper rod 201 and the lower rod 202 on the same side.

[0033] See Figure 2As shown, the structure of the sliding elongated hole 3 is as follows: the sliding elongated hole 3 includes an elongated hole 301 and multiple snap-fit ​​holes 302 connected to it. The snap-fit ​​holes 302 are arranged at equal intervals along the length direction of the elongated hole 301. One side of the snap-fit ​​hole 302 is provided with a snap-fit ​​groove 303 adapted to the snap-fit ​​unit. The opening structure of the snap-fit ​​hole 302 and the elongated hole 301 is as follows: the snap-fit ​​hole 302 is a rectangular hole, and the snap-fit ​​hole 302 is set perpendicular to the elongated hole 301. The length of the snap-fit ​​hole 302 is greater than the width of the elongated hole 301. By setting both ends of the snap-fit ​​hole 302 symmetrically arranged on both sides of the width direction of the elongated hole 301, the length direction of the snap-fit ​​hole 302 is consistent with the length direction of the switch cabinet body 1. This facilitates the installation of various components on the mounting plate 9, allowing for slight adjustments along the length direction of the switch cabinet body 1. It also allows the mounting plate 9 to move in the width direction of the switch cabinet body 1, which is convenient for disassembly and maintenance, and allows for reasonable arrangement of various components within the switch cabinet body 1 according to their space requirements.

[0034] See Figure 2 , Figure 5 and Figure 6 As shown, the structure of the snap-fit ​​unit is as follows: the snap-fit ​​unit includes a snap-fit ​​ball 4 and an elastic element 5. The side of the sliding rod 6 near the elongated hole 301 is provided with a mounting groove 601 that mates with the snap-fit ​​ball 4. The snap-fit ​​ball 4 is connected to the mounting groove 601 through the elastic element 5, and part of the snap-fit ​​ball 4 protrudes outward from the outside of the mounting groove 601. When the sliding rod 6 is moved into the corresponding snap-fit ​​hole 302, the snap-fit ​​ball 4 snaps into the snap-fit ​​groove 303, realizing the connection between the mounting plate 9 and the support frame 2. By moving the sliding rod 6 outward by external force, the snap-fit ​​ball 4 can be disengaged from the snap-fit ​​groove 303. The sliding rod 6 moves from the snap-fit ​​hole 302 into the elongated hole 301, which allows the position of the mounting plate 9 along the width direction of the switch cabinet body 1 to be adjusted. The width of the sliding rod 6 along the width direction of the switch cabinet body 1 is matched with the width of the snap-fit ​​hole 302, so that the sliding rod 6 will not wobble when it moves in the snap-fit ​​hole 302, thus avoiding the phenomenon that the snap-fit ​​ball 4 is snapped into the snap-fit ​​groove 303.

[0035] In the above structure, the mounting plate 9 is set on two symmetrically arranged support frames 2 and can move along the length or width of the switch cabinet body 1 on the support frames 2, which facilitates the installation or removal of components on the mounting plate 9. When installing or removing components, the mounting plate 9 can be moved towards the front and rear sides 102 or left and right sides of the switch cabinet body 1, so that it can be arranged in a way that suits the size or model of each component in the switch cabinet body 1, making reasonable use of the internal space of the switch cabinet body 1. When installing or removing components, the mounting plate 9 and the components on it can be moved outward by a certain distance, reducing the phenomenon of maintenance difficulties due to the small internal space of the switch cabinet body 1. The sliding rod 6 is moved to one side into the snap-fit ​​hole 302, so that the snap-fit ​​ball 4 snaps into the snap-fit ​​groove 303, realizing the connection between the mounting plate 9 and the support frame 2. This ensures that the mounting plate 9 will not move when installing or removing components, which facilitates installation, removal and maintenance work.

[0036] See Figure 6 As shown, to facilitate the disengagement of the snap-fit ​​ball 4 from the snap-fit ​​groove 303 under operator operation, the portion of the snap-fit ​​ball 4 protruding beyond the outer side of the mounting groove 601 is no more than half its volume. This allows the snap-fit ​​ball 4 to press inward against the elastic element 5 under external force along the length of the switchgear body 1, causing the snap-fit ​​ball 4 to move into the mounting groove 601 and disengage from the snap-fit ​​groove 303 as the sliding rod 6 moves, thus preventing the snap-fit ​​ball 4 from becoming stuck in the snap-fit ​​groove 303. To facilitate the manufacturing of the snap-fit ​​groove 303 on the support frame 2, the snap-fit ​​groove 303 is a semi-circular groove with a vertical length and open at both ends.

[0037] See Figure 3 , Figure 4 and Figure 7As shown, to facilitate the movement of the mounting plate 9 along its length or width within the switch cabinet body 1, a push-pull rod 8 is inserted into the sliding rod 6. The length of the push-pull rod 8 is less than the width of the switch cabinet body 1, facilitating the movement of the mounting plate 9. One end of the push-pull rod 8 is inserted into the sliding rod 6, allowing it to move along the length of the sliding rod 6, while the other end can overlap the overlapping hole. The insertion direction of the push-pull rod 8 and the sliding rod 6 is along the length of the switch cabinet body 1, facilitating the disassembly of the push-pull rod 8. Multiple push-pull rods 8 can be provided according to actual conditions. The push-pull rod 8 can be simultaneously installed on the sliding rods 6 on both sides of the mounting plate 9, facilitating the simultaneous pushing and pulling of both sides of the mounting plate 9. The aforementioned push-pull rod 8 is positioned such that a cabinet door 101 is located on the front side of the switch cabinet body 1, and a connecting plate is located on the side of the switch cabinet body 1 near the cabinet door 101. The connecting plate is vertically oriented and has multiple overlapping holes along its length. One end of the push-pull rod 8 extends outward through the overlapping hole. When installing or removing components on the mounting plate 9, the mounting plate 9 is moved closer to the cabinet door 101 by pulling the push-pull rod 8 outward, so that some components can be exposed from the switch cabinet body 1 for easy maintenance. Since the weight distribution of each component on the mounting plate 9 is different, in order to make it easier to pull out or push in the components with less effort, the height position of the push-pull rod 8 on the sliding rod 6 can be adjusted when the mounting plate 9 is inside the switch cabinet body 1.
