Description

Technical Field

[0001] This utility model relates to a switchgear installation foundation structure, specifically a wall-mounted low-voltage switchgear installation foundation structure. Background Technology

[0002] As a core piece of equipment in power distribution systems, the structural design and stability of the mounting foundation for low-voltage switchgear are of paramount importance. Wall-mounted installation effectively saves floor space, and its mounting foundation typically consists of a rigid frame fixed to the wall. This foundation structure not only bears the entire weight of the switchgear but is also crucial for ensuring its safe and stable operation. Therefore, simplifying and ensuring the reliability of the mounting foundation structure is fundamental to improving installation efficiency and quality.

[0003] Traditional wall-mounted installation bases rely primarily on the mechanical fastening between the base frame and the switchgear. Specifically, the mounting frame is first leveled and then secured to the wall using expansion bolts. Next, the switchgear is placed on the load-bearing beams of the frame and manually positioned by installers. Finally, multiple bolts are tightened from the side or inside of the switchgear to the corresponding holes in the mounting frame to complete the fixation. Throughout this process, the installation base only provides simple support and connection points.

[0004] Typically, the connection holes on the mounting frame and the switchgear are pre-drilled according to the design requirements, and the connection holes need to be aligned in height during installation; otherwise, the bolts will not be able to connect the switchgear to the foundation structure. However, in actual construction, the switchgear is heavy and the work is suspended, which increases the difficulty of aligning the holes and greatly increases the installation difficulty and workload. Utility Model Content

[0005] The purpose of this utility model is to provide an installation foundation structure for a wall-mounted low-voltage switchgear to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wall-mounted low-voltage switchgear installation base structure includes an installation frame, which is connected to the wall by bolts; It also includes a support plate, installed within the mounting frame, for supporting the low-voltage switchgear; The connector includes a second clamping block rotatably mounted on the mounting frame; during the installation of the low-voltage switchgear, the second clamping block can be rotated so that the second clamping block abuts against the back plate of the switchgear. It also includes a positioning element, which is used to make the centerline of the switch cabinet coincide with the centerline of the support plate.

[0007] The installation base structure of the wall-mounted low-voltage switchgear as described above: the positioning component includes multiple sets of positioning plates that are slidably mounted on the support plate; and the multiple sets of positioning plates are symmetrically arranged; the support plate is provided with positioning springs; and the two ends of the positioning springs respectively abut against the positioning plates and the support plate.

[0008] The installation base structure of the wall-mounted low-voltage switchgear as described above: an inclined baffle is installed on the end of the positioning plate away from the mounting frame.

[0009] The installation base structure of the wall-mounted low-voltage switchgear as described above: the connector also includes a fixing sleeve installed on the mounting frame; A sliding sleeve is slidably fitted with a fixed sleeve. A return spring is provided inside the fixed sleeve, and the two ends of the return spring abut against the fixed sleeve and the sliding sleeve, respectively. A rotating rod that is sleeved with the sliding sleeve is rotatably installed inside the fixed sleeve, and the rotating rod is fixedly connected to the second clamping block. A first clamping block is installed at the end of the sliding sleeve near the second clamping block.

[0010] The installation base structure of the wall-mounted low-voltage switchgear as described above: the rotating rod is provided with an inclined groove; the sliding sleeve is provided with a protruding column that slides and engages with the inclined groove.

[0011] The installation base structure of the wall-mounted low-voltage switchgear as described above: symmetrically arranged partitions are installed on the installation frame, and heat dissipation grooves for maintaining air circulation are opened on the partitions.

[0012] The installation base structure of the wall-mounted low-voltage switchgear described above: both the mounting frame and the support plate are made of high-strength aluminum alloy.

[0013] Compared with the prior art, the beneficial effects of this utility model are: When installing low-voltage switchgear, the position of the switchgear is adjusted using positioning components to ensure it is parallel and close together, and that the centerline of the switchgear coincides with that of the support plate. This improves installation efficiency and saves labor costs, while also increasing installation accuracy, preventing the switchgear from tilting, and thus enhancing post-installation stability. After the switchgear is connected, connectors restrict its displacement to prevent separation from the mounting frame during use, thereby improving stability. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-7 As an embodiment of this utility model, the mounting base structure of the wall-mounted low-voltage switchgear includes a mounting frame 1, which is connected to the wall by bolts. It also includes a support plate 2, which is installed inside the mounting frame 1; used to support the low-voltage switchgear; The connector includes a second clamping block 8 rotatably mounted on the mounting frame 1; during the installation of the low-voltage switchgear, the second clamping block 8 can be rotated so that the second clamping block 8 abuts against the back plate of the switchgear. It also includes a positioning element, which is used to make the center line of the switch cabinet coincide with the center line of the support plate 2.

[0024] In this embodiment, after the mounting frame 1 is connected to the wall, the low-voltage switchgear is installed.

[0025] When installing low-voltage switchgear, first place the low-voltage switchgear on the support plate 2; then apply external force to push the switchgear closer to the mounting frame 1 (sliding on the support plate 2); during the approach process, adjust the position of the switchgear using positioning components to make the switchgear parallel and close together, and to make the center line of the switchgear coincide with that of the support plate 2; on the one hand, this can improve installation efficiency and save labor costs; on the other hand, it can improve installation accuracy, prevent the switchgear from tilting, and thus improve the stability after installation.

[0026] During the connection process of the switch cabinet, the back plate of the switch cabinet can cooperate with the connector, thereby driving the second clamping block 8 to rotate (from a vertical state to a horizontal state); and during the rotation, the side of the second clamping block 8 close to the mounting frame 1 abuts against the back plate of the switch cabinet, thereby restricting the displacement of the switch cabinet and preventing the switch cabinet from separating from the mounting frame 1 during use, thereby improving stability.

[0027] As a further embodiment of this utility model, the positioning component includes multiple sets of positioning plates 3 slidably mounted on the support plate 2; and the multiple sets of positioning plates 3 are symmetrically arranged; a positioning spring 4 is provided on the support plate 2; and the two ends of the positioning spring 4 respectively abut against the positioning plate 3 and the support plate 2.

[0028] As a further embodiment of this utility model, an inclined baffle 301 is installed on the end of the positioning plate 3 away from the mounting frame 1.

[0029] In this embodiment, the width of the switch cabinet is greater than the spacing between the multiple sets of positioning plates 3, and less than the spacing between the tops of the multiple sets of baffles 301.

[0030] When the switchgear slides closer to the mounting frame 1 on the support plate 2, it will first contact the baffle 301; and after contact, the kinetic energy of the switchgear movement will drive the positioning plates 3 to move away from each other through the inclined baffle 301, and compress the positioning spring 4.

[0031] After the switch cabinet disengages from the baffle 301, the positioning plate 3 clamps the switch cabinet from both sides, and under the elastic force of multiple positioning springs 4, the center line of the switch cabinet will move closer to and coincide with the center line of the support plate 2.

[0032] The positioning function of the positioning components can improve installation efficiency and save labor costs; on the other hand, it can improve installation accuracy, prevent switch cabinet tilting, and thus improve post-installation stability.

[0033] As a further embodiment of this utility model, the connector also includes a fixing sleeve 5 installed on the mounting frame 1; A sliding sleeve 6 is slidably fitted with a fixed sleeve 5. A return spring 9 is provided inside the fixed sleeve 5. The two ends of the return spring 9 abut against the fixed sleeve 5 and the sliding sleeve 6, respectively. A rotating rod 7 is rotatably installed inside the fixed sleeve 5 and is sleeved with the sliding sleeve 6. The rotating rod 7 is fixedly connected to the second clamping block 8. A first clamping block 601 is installed at one end of the sliding sleeve 6 near the second clamping block 8.

[0034] As a further embodiment of this utility model, the rotating rod 7 is provided with a slanted groove 701; the sliding sleeve 6 is provided with a protruding post 602 that slides and engages with the slanted groove 701.

[0035] In this embodiment, under the action of the positioning element, the center line of the switch cabinet coincides with the center line of the support plate 2, and then the switch cabinet is pushed closer to the mounting frame 1.

[0036] The back panel of the switch cabinet has a slot slightly larger than the second clamping block 8; and the first clamping block 601 abuts against the second clamping block 8. During the approach process, the second clamping block 8 will pass through the slot; then the back panel of the switch cabinet will contact the first clamping block 601, and the moving switch cabinet will drive the sliding sleeve 6 to slide inward in the fixed sleeve 5 through the first clamping block 601, and compress the return spring 9, thereby driving the protruding column 602 to approach from one end to the other in the inclined groove 701; through the squeezing action of the protruding column 602 on the groove wall of the inclined groove 701, the rotating rod 7 will rotate, thereby driving the second clamping block 8 to rotate; causing the second clamping block 8 to be misaligned with the slot, thereby limiting the switch cabinet.

[0037] The spring force of the return spring 9 is much smaller than that of the positioning spring 4. Therefore, when the second clamping block 8 is misaligned with the slot, the spring force of the return spring 9 is far from sufficient to push the switch cabinet to move in the opposite direction. Thus, the connecting parts can effectively limit the switch cabinet, preventing external forces from causing the switch cabinet to overturn and resulting in serious damage. This effectively simplifies the installation process and improves installation efficiency.

[0038] As a further embodiment of this utility model, the mounting frame 1 is equipped with symmetrically arranged partitions 10, and the partitions 10 are provided with heat dissipation grooves 1001 for maintaining air circulation.

[0039] In this embodiment, the partition 10 reduces the probability of foreign objects contacting the back panel of the switch cabinet, preventing heat dissipation from being obstructed and thus ensuring the safe operation of the switch cabinet. The opening of the heat dissipation slot 1001 effectively ensures air circulation at the back of the switch cabinet, preventing heat accumulation that could lead to switch cabinet malfunctions.

[0040] As a further improvement of this utility model, both the mounting frame 1 and the support plate 2 are made of high-strength aluminum alloy.

[0041] In this embodiment, the high-strength aluminum alloy mounting frame 1 and support plate 2 can improve the stability of the connection, prevent the support plate 2 from bending and deforming under the weight of the switch cabinet during use, and also prevent the mounting frame 1 from falling off the wall.

[0042] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
