Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter cabinet technology, and more specifically, to an assemblable active filter cabinet. Background Technology
[0002] A power filter cabinet is an important piece of equipment in a power system, used to reduce unwanted current or voltage fluctuations caused by various factors; these fluctuations are called harmonics. The main function of the power filter cabinet is to reduce the impact of harmonics and ensure the stable operation of the power system.
[0003] An existing patent describes an assemblable active filter cabinet (patent authorization number CN219086653U), which includes a cabinet body with drawers inside. The upper surface of the cabinet has two recessed slots arranged along the front-to-back direction. The lower surface of the cabinet is fixedly connected to two insert strips that match the recessed slots. The left side wall of the cabinet has two vertically distributed insert blocks fixedly connected to it. Each insert block has a through hole in its outer wall. The two insert blocks from one cabinet are inserted into two slots in the other cabinet. When the insert blocks are fully inserted, their through holes coincide with the front-to-back limiting slots. Then, a limiting post is inserted from the front of the limiting slot. This limiting post passes through the two through holes, thus firmly locking the two insert blocks into the slots, completing the left-right assembly of the two cabinets. The assembly is strong, the connection is tight, preventing shaking and loosening, and making it more convenient to use.
[0004] However, the internal space of the assembled cabinet in patent authorization number CN219086653U cannot be adjusted. Due to the different sizes of the equipment installed inside, the limited space inside the cabinet cannot be effectively utilized. Therefore, we propose an assemblable active filter cabinet to solve the above-mentioned problems. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide an assembly-type active filter cabinet, which can adjust the spacing between the support plates according to the size of the installed equipment, and can effectively make use of the limited space inside the cabinet.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] An assemblable active filter cabinet includes a base, wherein dovetail slots are symmetrically provided on the upper surface edge of the base.
[0010] A dovetail block is embedded in the inner side of the dovetail slot, and a galvanized steel pipe is welded to the top of the dovetail block. An adjustment hole is opened on the outer wall of the galvanized steel pipe, and multiple adjustment holes are arranged longitudinally at equal intervals.
[0011] The galvanized steel pipe is fitted with side plates, back plates, top plates, and cabinet doors on its outer side.
[0012] A support plate is installed between the horizontally arranged galvanized steel pipes. An adjustment protrusion that engages with the adjustment hole is installed on the side wall of the support plate. A storage cavity is opened on the support plate corresponding to the adjustment protrusion. A spring is installed inside the storage cavity. A baffle is provided on one side of the spring that is clearance-fitted with the storage cavity and connected to the adjustment protrusion.
[0013] Furthermore, a crossbar is installed between the two longitudinally arranged galvanized steel pipes;
[0014] Both ends of the crossbar are fixedly connected to connecting lugs, and the connecting lugs are connected to the galvanized steel pipe by screws.
[0015] Furthermore, two side plates are symmetrically arranged;
[0016] Both the side plate and the back plate are connected to the galvanized steel pipe by screws;
[0017] The top plate is connected to the top of the side plate by screws;
[0018] The cabinet door is connected to the side panel via hinges.
[0019] Furthermore, the sidewall of the adjusting protrusion is provided with a first inclined surface, and the first inclined surface extends to the port of the receiving cavity.
[0020] Furthermore, the top of the adjusting protrusion is provided with a second inclined surface, and the second inclined surface extends to the port position of the receiving cavity.
[0021] Furthermore, one end of the spring is connected to the baffle, and the other end of the spring is connected to the end wall of the receiving cavity.
[0022] Furthermore, a limiting part for blocking the baffle is provided at the port edge of the receiving cavity.
[0023] 3. Beneficial effects
[0024] Compared with existing technologies, the advantages of this utility model are:
[0025] (1) In this solution, the spacing between the support plates is adjusted according to the size of the equipment to be installed. By dragging the support plate upward, the second inclined surface set on the top of the adjusting protrusion abuts against the top of the adjusting hole. Under the action of pressure, the adjusting protrusion is pressed into the storage cavity, and the spring is compressed and deformed. When the adjusting protrusion moves to the corresponding adjusting hole, the elastic force of the spring is used to pop out the adjusting protrusion located in the storage cavity. At the same time, the baffle limits the position. Thus, the spacing between the support plates can be adjusted according to the size of the equipment to be installed, which can effectively make use of the limited space inside the cabinet.
[0026] (2) In this scheme, by fixing the crossbar between two longitudinally arranged galvanized steel pipes, the stability and structural strength between the two adjacent galvanized steel pipes can be effectively guaranteed, which is conducive to the assembly of the active filter cabinet.

[0037] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0038] Example:
[0039] Please see Figure 1-8 An assemblable active filter cabinet includes a base 1, with dovetail slots 2 symmetrically provided on the upper surface edge of the base 1.
[0040] A dovetail block 3 is embedded in the inner side of the dovetail slot 2. A galvanized steel pipe 4 is welded to the top of the dovetail block 3. An adjustment hole 5 is opened on the outer wall of the galvanized steel pipe 4, and multiple adjustment holes 5 are arranged longitudinally at equal intervals.
[0041] The outer side of the galvanized steel pipe 4 is respectively equipped with side plates 7, back plates 8, top plates 9 and cabinet doors 10;
[0042] A support plate 11 is installed between the horizontally arranged galvanized steel pipes 4. An adjustment protrusion 12 that engages with the adjustment hole 5 is installed on the side wall of the support plate 11. A storage cavity 15 is opened on the support plate 11 corresponding to the adjustment protrusion 12. A spring 16 is installed inside the storage cavity 15. A baffle 17 that is clearance-fitted with the storage cavity 15 and connected to the adjustment protrusion 12 is provided on one side of the spring 16.
[0043] The top of the adjusting protrusion 12 is provided with a second inclined surface 14, and the second inclined surface 14 extends to the port position of the storage cavity 15.
[0044] It should be noted that when assembling the active filter cabinet, the dovetail clip 3 is first engaged and connected to the inside of the dovetail slot 2. Then, the side plate 7 and the back plate 8 are assembled together with the galvanized steel pipe 4 using screws. The top plate 9 is connected to the side plate 7 using screws. The cabinet door 10 is assembled together with the side plate 7 using hinges.
[0045] Finally, the support plate 11 is placed between the horizontally arranged galvanized steel pipes 4. The spacing between the support plates 11 is adjusted according to the size of the equipment to be installed. By dragging the support plate 11 upward, the second inclined surface 14 on the top of the adjusting protrusion 12 abuts against the top of the adjusting hole 5. Under pressure, the adjusting protrusion 12 is pressed into the storage cavity 15, and the spring 16 is compressed and deformed. When the adjusting protrusion 12 moves to the corresponding adjusting hole 5, the elastic force of the spring 16 pops the adjusting protrusion 12 in the storage cavity 15 out. At the same time, the baffle 17 limits the movement. Thus, the spacing between the support plates 11 can be adjusted according to the size of the equipment to be installed, which can effectively utilize the limited space inside the cabinet.
[0046] like Figure 4 As shown, a crossbar 6 is installed between two longitudinally arranged galvanized steel pipes 4;
[0047] Both ends of the crossbar 6 are fixedly connected with connecting ears, and the connecting ears are connected to the galvanized steel pipe 4 by screws;
[0048] It should be noted that by fixing the crossbar 6 between the two longitudinally arranged galvanized steel pipes 4, the stability and structural strength between the two adjacent galvanized steel pipes 4 can be effectively guaranteed, which is beneficial to the assembly of the active filter cabinet.
[0049] like Figure 3 As shown, there are two side panels 7 arranged symmetrically;
[0050] Both the side plate 7 and the back plate 8 are connected to the galvanized steel pipe 4 by screws;
[0051] The top plate 9 is connected to the top of the side plate 7 by screws;
[0052] Cabinet door 10 is connected to side panel 7 via hinges;
[0053] It should be noted that the side panel 7, back panel 8, top panel 9 and cabinet door 10 are convenient for assembling the active filter cabinet.
[0054] like Figure 5 As shown, the side wall of the adjusting protrusion 12 is provided with a first inclined surface 13, and the first inclined surface 13 extends to the port of the receiving cavity 15.
[0055] It should be noted that by setting the first inclined surface 13, when the support plate 11 is placed between the horizontally arranged galvanized steel pipes 4, the first inclined surface 13 abuts against the corner of the galvanized steel pipe 4, thereby pressing the adjusting protrusion 12 into the storage cavity 15, which facilitates the installation of the support plate 11.
[0056] like Figure 8 As shown, one end of the spring 16 is connected to the baffle 17, and the other end of the spring 16 is connected to the end wall of the receiving cavity 15.
[0057] It should be noted that the elastic force of the spring 16 is used to allow the adjusting protrusion 12 to extend and retract freely, thereby facilitating the adjustment of the support plate 11.
[0058] like Figure 8 As shown, a limiting part for blocking the baffle 17 is provided at the edge of the port of the receiving cavity 15;
[0059] It should be noted that the baffle 17 abuts against the limiting part to prevent the adjusting protrusion 12 from disengaging from the storage cavity 15.
[0060] When in use: First, engage the dovetail clip 3 with the inside of the dovetail slot 2, then assemble the side panel 7 and the back panel 8 together with the galvanized steel pipe 4 using screws, connect the top panel 9 to the side panel 7 with screws, and assemble the cabinet door 10 together with the side panel 7 using hinges.
[0061] Finally, the support plate 11 is placed between the horizontally arranged galvanized steel pipes 4. The spacing between the support plates 11 is adjusted according to the size of the equipment to be installed. By dragging the support plate 11 upward, the second inclined surface 14 on the top of the adjusting protrusion 12 abuts against the top of the adjusting hole 5. Under pressure, the adjusting protrusion 12 is pressed into the storage cavity 15, and the spring 16 is compressed and deformed. When the adjusting protrusion 12 moves to the corresponding adjusting hole 5, the elastic force of the spring 16 pops the adjusting protrusion 12 in the storage cavity 15 out. At the same time, the baffle 17 limits the movement, thus completing the adjustment of the support plate 11.
[0062] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
