[0002] The keel structure of a low-voltage switchgear is its core support frame, equivalent to the "skeleton" of the switchgear. It is mainly used to support the internal functional modules (such as circuit breakers, busbars, control units, etc.), transmit mechanical loads (self-weight, external impact, etc.), and achieve rapid assembly, stable fixation, and electrical / mechanical protection of the modules through standardized design.
[0003] Common keel structures include a frame composed of multiple sets of columns, beams, and longitudinal beams; they also include partitions set on the frame to divide the frame; usually, the various functional modules of low-voltage switchgear are fixedly installed on the partitions; the partitions and the frame are usually fixedly connected by bolts or rivets.
[0004] Whether using bolts or rivets for connection, tools are required; however, due to the limited and relatively small space within the frame, as the installation progresses, the space where tools can be used flexibly becomes increasingly smaller, resulting in relatively low installation efficiency.

[0036] 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.
[0037] Please see Figures 1-6 As an embodiment of this utility model, the modular assembly low-voltage switchgear keel structure includes multiple sets of columns 1, crossbeams 2, and longitudinal beams 3; the columns 1, crossbeams 2, and longitudinal beams 3 are connected by bolts to form a frame;
[0038] It also includes multiple sets of partitions 4, which are used to divide the frame into multiple chambers;
[0039] The partition 4 is equipped with symmetrically arranged fixing plates 7; the fixing plates 7 are provided with limiting grooves 701;
[0040] A connector, provided on the column 1, includes a limiting plate 10 that mates with the limiting groove 701;
[0041] It also includes a positioning element, which is used to assist the limiting plate 10 in cooperating with the limiting groove 701.
[0042] In this embodiment, multiple sets of columns 1 are fixedly connected to the crossbeams 2 and longitudinal beams 3 by bolts to form a relatively stable and solid frame system, thereby preventing the keel from collapsing and disintegrating after the installation of various components of the low-voltage switchgear, and also relatively improving the service life of the low-voltage switchgear.
[0043] After installing partition 4, the frame can be divided into multiple chambers to facilitate the installation and separation of various functional modules of the low-voltage switchgear, thereby maximizing the utilization of space within the effective space. Furthermore, the separation of each module by partition 4 can prevent mutual interference between modules and improve the stability of the low-voltage switchgear.
[0044] Installation process of partition 4: The partition 4 is pushed horizontally into the cavity. During the pushing process, the positioning function of the positioning component enables the limiting plate 10 to be aligned with the limiting groove 701. At this time, the limiting plate 10 can pass through the limiting groove 701.
[0045] After the limiting plate 10 passes through the limiting groove 701, it continues to push the partition 4. During this process, the limiting plate 10 will rotate so that it is misaligned with the limiting groove 701. At this time, the mutual pressing and cooperation between the limiting plate 10 and the limiting groove 701 achieves a stable connection between the partition 4 and the column 1.
[0046] The connectors allow for quick connection between the partition 4 and the column 1, making the connection process relatively simple. After the connection is completed, the connection strength is relatively high, which facilitates the installation of the low-voltage switchgear frame structure and improves installation efficiency. Furthermore, it can reduce the workload of installation in relatively confined spaces.
[0047] As a further embodiment of this utility model, the connector further includes a fixed sleeve 8 installed on the column 1; a rotating rod 9 rotatably connected to the column 1 is provided inside the fixed sleeve 8, and the rotating rod 9 is fixedly connected to the limiting plate 10; a sliding sleeve 12 slidably connected to the fixed sleeve 8 is sleeved on the rotating rod 9; multiple sets of grooves are provided on the rotating rod 9; a protruding post 1201 slidably engaged with the grooves is installed inside the sliding sleeve 12; a spring 11 is wrapped around the rotating rod 9; the two ends of the spring 11 respectively abut against the sliding sleeve 12 and the column 1.
[0048] As a further embodiment of the present invention, the connector further includes a baffle 1202 installed on the sliding sleeve 12, the diameter of the baffle 1202 being greater than the groove length of the limiting groove 701.
[0049] In this embodiment, the partition 4 is pushed forward under the positioning action of the positioning member; during the pushing process, the partition 4 will drive the fixed plate 7 to move, thereby driving the limiting groove 701 to move closer to the limiting plate 10.
[0050] In the initial state, the limiting plate 10 and the limiting groove 701 are aligned with each other. Therefore, during the movement of the limiting groove 701, the limiting plate 10 will convey the limiting groove 701, and after passing through, the fixing plate 7 will abut against the baffle 1202.
[0051] Then, the partition 4 continues to be pushed forward. During this process, the fixed plate 7 will press against the baffle 1202 and drive the baffle 1202 to move synchronously, thereby pushing the sliding sleeve 12 to slide inward on the fixed sleeve 8 to compress the spring 11. During this process, under the sliding cooperation of the groove and the protruding column 1201, the rotating rod 9 will rotate, thereby driving the limiting plate 10 to rotate.
[0052] Then the external force that pushes the partition 4 to move is removed; at this time, under the elastic force of the spring 11, the sliding sleeve 12 will move outward inside the fixed sleeve 8, thereby driving the fixed plate 7 to move through the baffle 1202, so as to drive the partition 4 to move; during this process, the groove group and the protruding column 1201 slide together, thereby continuing to drive the rotating rod 9 to rotate, so as to drive the limiting plate 10 to rotate; until the fixed plate 7 and the limiting plate 10 abut against each other, the partition 4 is installed.
[0053] Throughout the process, the rotation of the rotating rod 9 causes the position of the limiting plate 10, which was originally aligned with the limiting groove 701, to change, that is, the limiting plate 10 and the limiting groove 701 are misaligned; when the fixed plate 7 and the limiting plate 10 are in contact, the partition plate 4 and the column 1 are stably connected.
[0054] The connectors allow for quick connection between the partition 4 and the column 1, making the connection process relatively simple. After the connection is completed, the connection strength is relatively high, which facilitates the installation of the low-voltage switchgear frame structure and improves installation efficiency. Furthermore, it can reduce the workload of installation in relatively confined spaces.
[0055] In the initial state, the spring 11 is compressed and the baffle 1202 is in contact with the limiting plate 10. After the limiting plate 10 and the limiting groove 701 are misaligned, the fixing plate 7 is located between the limiting plate 10 and the baffle 1202, thereby increasing the compression of the spring 11. The elastic force of the spring 11 can make the partition 4 installed stably, and the elastic force of the spring 11 can offset or eliminate the vibration generated by the module during the use of the low-voltage cabinet, thereby further improving the stability of the connection.
[0056] As a further embodiment of this utility model, the groove group includes a first straight groove 901, a first inclined groove 902, a second straight groove 903, and a second inclined groove 904; one end of the first straight groove 901 is connected to one end of the first inclined groove 902; the other end of the first inclined groove 902 is connected to one end of the second straight groove 903; the other end of the second straight groove 903 is connected to one end of the second inclined groove 904; and the other end of the second inclined groove 904 is connected to the first straight groove 901 in another set of the groove group.
[0057] In this embodiment, when the sliding sleeve 12 slides inward within the fixed sleeve 8, the protruding post 1201 first slides towards the first inclined groove 902 within the first straight groove 901, at which time the rotating rod 9 does not rotate. Then, the protruding post 1201 slides towards the second straight groove 903 within the first inclined groove 902. During this process, the groove wall of the first inclined groove 902 presses against the protruding post 1201, thereby causing the rotating rod 9 to rotate, which in turn causes the limiting plate 10 to rotate.
[0058] When the sliding sleeve 12 slides outward within the fixed sleeve 8, the protruding post 1201 will first slide from the second straight groove 903 towards the second inclined groove 904, at which time the rotating rod 9 will not rotate; then the protruding post 1201 will slide from the second inclined groove 904 towards the first straight groove 901. During this process, the groove wall of the second inclined groove 904 will squeeze the protruding post 1201, thereby driving the rotating rod 9 to rotate, which in turn drives the limiting plate 10 to rotate.
[0059] The connectors allow for quick connection between the partition 4 and the column 1, making the connection process relatively simple. After the connection is completed, the connection strength is relatively high, which facilitates the installation of the low-voltage switchgear frame structure and improves installation efficiency. Furthermore, it can reduce the workload of installation in relatively confined spaces.
[0060] As a further embodiment of this utility model, the positioning component includes a guide plate 6 installed on the partition 4; and a guide rail 5 that slides and engages with the guide plate 6 is installed on the column 1.
[0061] In this embodiment, after the guide plate 6 is slidably connected to the guide rail 5, the partition 4 will be in a horizontal state, and the partition 4 can be limited in the vertical direction through the sliding connection between the guide plate 6 and the guide rail 5; then push the partition 4 so that the guide plate 6 slides on the guide rail 5, thereby making the partition 4 move horizontally closer to the limiting plate 10, thereby facilitating the limiting of the partition 4 by the connecting member.
[0062] As a further improvement of this utility model, multiple sets of reinforcing ribs 401 are installed on the partition 4.
[0063] In this embodiment, the reinforcing rib 401 can effectively improve the bending resistance of the partition 4, thereby improving the load-bearing capacity of the low-voltage cabinet keel.
[0064] 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.
