Description

Technical Field

[0001] This application relates to the field of electrical equipment installation cabinet technology, and in particular to a prefabricated switch cabinet. Background Technology

[0002] Switchgear is a type of electrical equipment mainly used in various settings such as power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, residential communities, and high-rise buildings. Switchgear primarily consists of a cabinet and multiple components installed within it. The cabinet is typically assembled from a frame and several sheet metal panels. During assembly, the frame is usually welded first, and then the sheet metal panels are installed onto the frame.

[0003] In related technologies, when installing the sheet metal plate on the side of the frame onto the frame, multiple hanging columns are first welded at intervals on the outer wall of the frame, and multiple hanging holes in the shape of an inverted gourd are opened on the side of the sheet metal plate near the frame. The hanging holes do not penetrate the sheet metal plate. Then, each hanging column is aligned with the corresponding hanging hole and the hanging column is inserted into the hanging hole, thereby realizing the installation of the sheet metal plate on the side of the frame.

[0004] Regarding the aforementioned technologies, since the hanging holes are located on the side of the sheet metal plate near the frame and do not penetrate the sheet metal plate, it is not possible to directly observe whether the hanging column is aligned with the corresponding hanging hole when installing the side panel. At the same time, it is even more difficult to ensure that multiple hanging columns are aligned with the corresponding hanging holes. Therefore, when installing the sheet metal plate on the side of the frame, it is necessary to constantly adjust the position of the sheet metal plate, which makes it inconvenient to assemble the side panel of the switch cabinet. Utility Model Content

[0005] To improve the ease of assembling the side panels of the switchgear, this application provides a prefabricated switchgear.

[0006] This application provides a prefabricated switchgear, which adopts the following technical solution:

[0007] A prefabricated switch cabinet includes a frame and side panels. Dovetail blocks are provided on the side walls of the frame. A connecting strip is welded to the side panel near the frame. A dovetail groove is provided on the connecting strip for the dovetail blocks to insert into. The dovetail groove is provided along the extension direction of the connecting strip.

[0008] In order to allow the dovetail block to be inserted into the dovetail groove more smoothly, a threaded post is provided on the side of the dovetail block near the frame. The frame has a floating hole for the threaded post to be inserted and passed through before connecting with the nut. The diameter of the floating hole is larger than the outer diameter of the threaded post.

[0009] To improve the stability of the side plate after it is installed on the frame, multiple dovetail blocks are provided, and the multiple dovetail blocks are arranged at intervals on the frame along the extension direction of the dovetail groove.

[0010] In order to enable multiple dovetail blocks to move synchronously and more conveniently align with and insert into the dovetail groove, the dovetail blocks are provided with connecting through holes on the outer wall along the sliding insertion direction of the side plate, and a linkage rod is inserted into the connecting through hole. Multiple dovetail blocks are all sleeved on the linkage rod.

[0011] To prevent large gaps from forming between the side panel and the frame, the side panel is bent with a flange that fits against the frame on the side closest to the frame, and a dovetail opening that communicates with the dovetail groove is provided on one side of the flange.

[0012] To facilitate the smooth insertion of the dovetail block into the dovetail groove at the beginning, a guide slope is provided around the dovetail opening to facilitate the insertion of the dovetail block into the dovetail groove.

[0013] To ensure the side panel can be accurately installed, a blocking strip is inserted into the dovetail groove to limit the movement of the side panel. The blocking strip is located on the side of the dovetail groove away from the dovetail opening.

[0014] To prevent the side panel from easily detaching from the frame along its own sliding direction after installation, a fixing bolt is provided on the side of the side panel facing away from the frame to limit the side panel to the frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] When installing the side panel, simply insert the dovetail block into the dovetail groove and then push the side panel to move. During the insertion process, the staff can visually observe from the side panel whether the dovetail block is aligned with the dovetail groove, thus making the installation of the side panel more convenient.

[0017] Because the diameter of the floating hole is larger than the outer diameter of the threaded column, the dovetail block has a certain amount of room to move on the frame, so that when the dovetail block is initially aligned with the dovetail groove, it can automatically adjust its position and be inserted into the dovetail groove more smoothly.

[0018] To prevent the side panels from sliding off the frame along their own sliding installation direction, bolts are used to fix the side panels to the frame from the outer wall of the side panels, thereby improving the stability of the side panels after installation. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a prefabricated switchgear. (Refer to...) Figure 1 and Figure 2 The prefabricated switchgear includes a frame 1 and a side panel 2. Dovetail blocks 3 are installed on the side walls of the frame 1. A connecting strip 21 is welded to the side of the side panel 2 near the frame 1. The connecting strip 21 has dovetail grooves 22 for inserting the dovetail blocks 3, and these grooves extend along the connecting strip 21. When installing the side panel 2, the dovetail blocks 3 are inserted into the dovetail grooves 22, and then the side panel 2 is moved. During the insertion process, the operator can visually observe whether the dovetail blocks 3 are aligned with the dovetail grooves 22 from the side panel 2, thus making the installation of the side panel 2 more convenient.

[0026] Frame 1 is a rectangular frame 1 formed by splicing and welding multiple steel pipes together.

[0027] Reference Figure 1 and Figure 2 Multiple dovetail blocks 3 are provided, and the multiple dovetail blocks 3 are arranged at intervals on the frame 1 along the direction of sliding installation of the side plate 2. If multiple dovetail blocks 3 in the same horizontal direction are set as a group of guide components, then in this embodiment, multiple groups of guide components are preferably arranged along the vertical direction.

[0028] Combination Figure 1 Reference Figure 2 and Figure 3A threaded post 31 is welded to the side of the dovetail block 3 near the frame 1. A floating hole 11 is provided on the outer wall of the steel pipe of the frame 1 near the dovetail block 3 for inserting the threaded post 31. The floating hole 11 passes through the corresponding steel pipe. The end of the threaded post 31 facing away from the dovetail block 3 passes through the floating hole 11 and is connected to a nut, thus fixing the dovetail block 3 to the frame 1. The floating hole 11 is an oblong hole with a diameter larger than the outer diameter of the threaded post 31. The floating hole 11 extends vertically. When the dovetail block 3 is inserted into the dovetail groove 22, the dovetail block 3 can adjust its position under the action of the floating hole 11, making the insertion process of the dovetail block 3 into the dovetail groove 22 simpler.

[0029] Combination Figure 1 Reference Figure 2 and Figure 3 The dovetail block 3 has a connecting through hole 32 on its outer wall along the sliding insertion direction of the side plate 2. The connecting through hole passes through the dovetail block 3, and a linkage rod 33 is inserted into the connecting through hole 32. The connecting through holes 32 on multiple dovetail blocks 3 are all fitted onto the linkage rod 33, so that multiple dovetail blocks 3 can move synchronously to adjust their positions. In order to prevent the linkage rod 33 from easily disengaging from the dovetail block 3, nuts are threaded onto both ends of the linkage rod 33.

[0030] Combination Figure 1 Reference Figure 2 and Figure 4 The side plate 2 has a rectangular flange 23 bent on the side near the frame 1, which fits against the frame 1. The connecting strip 21 is located inside the rectangular flange 23. A dovetail opening 24 communicating with the dovetail groove 22 is provided on the flange 23 on the side that slides along the side plate 2. In order to make it easier for the dovetail block 3 to enter the dovetail groove 22 through the dovetail opening 24, a guide slope 25 is provided on the inner edge of the periphery of the dovetail opening 24.

[0031] Combination Figure 1 Reference Figure 2 and Figure 4 A blocking strip 26 is inserted into the side of the dovetail groove 22 away from the dovetail opening 24. The blocking strip 26, on the side away from the dovetail opening 24, abuts against the inner wall of the flange 23 and is limited. A clearance hole is provided on the side of the blocking strip 26 near the dovetail block 3 for the insertion of the linkage rod 33 and the nut on the linkage rod 33. When the dovetail block 3 on the side away from the dovetail opening 24 abuts against the blocking strip 26, the sliding of the side plate 2 will be limited, and thus installed in place. In order to prevent the side plate 2 from sliding off the frame 1 along its own sliding installation direction, a fixing bolt 27 is installed on the outer wall of the side plate 2. The fixing bolt 27 is threaded onto the frame 1.

[0032] The implementation principle of a prefabricated switchgear according to an embodiment of this application is as follows: When installing the side plate 2, the dovetail block 3 is inserted into the dovetail groove 22 and then the side plate 2 is moved. During the insertion of the dovetail block 3 into the dovetail groove 22, the operator can visually observe from the side plate 2 whether the dovetail block 3 is aligned with the dovetail groove 22. Since the diameter of the floating hole 11 is larger than the outer diameter of the threaded post 31, the dovetail block 3 has a certain amount of play on the frame 1, so that when the dovetail block 3 is initially aligned with the dovetail groove 22, it can automatically adjust its position and be inserted into the dovetail groove 22 more smoothly. Finally, after the blocking strip 26 abuts against the dovetail block 3, the fixing bolt 27 is threaded onto the frame 1, thereby limiting the side plate 2 to the frame 1, making it difficult for the side plate 2 to slide off the frame 1 along its own sliding direction.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
