Description

Technical Field

[0001] This application relates to the technical field of switching electrical appliances, and in particular to a split-type base assembly and a power conversion switch device. Background Technology

[0002] The main function of a dual power transfer switch is to switch to another backup power source when the main power supply is disconnected due to a fault. It is widely used in hospitals, airports, docks, fire fighting, metallurgy, chemical industry and other occasions where power outages are not allowed.

[0003] Dual power transfer switches are available in two types: integrated and separate. Integrated switches mount the controller and switch module on a single base; separate switches mount the controller on a cabinet panel and the switch module on a separate base, which is then installed by the user inside the cabinet. Integrated dual power transfer switches are more commonly used in the market than separate switches. This is because the integrated structure shortens the connecting cable length, improves equipment reliability, and reduces heat loss.

[0004] For integrated dual-power transfer switch devices, the structure can be referenced from the "An Automatic Dual-Power Transfer Switch" disclosed in Chinese Invention Patent Publication No. CN116013709A. This includes a controller and a switch module, with the switch module further comprising a contact mechanism and an operating mechanism connecting to the contact mechanism. The controller and switch module are mounted on a single base. Currently, switch modules have three-phase three-wire, three-phase four-wire, and three-phase five-wire wiring configurations, each corresponding to a different number of contacts. The existing integrated base structure of switch devices cannot accommodate the installation dimensions of switch modules with different wiring configurations, requiring the custom fabrication of bases of corresponding dimensions to accommodate the installation of the switch module and controller, thus increasing manufacturing costs. Utility Model Content

[0005] In order to accommodate the installation of switching elements and controllers of different sizes and reduce manufacturing costs, the primary objective of this application is to provide a split base assembly.

[0006] The split-type base assembly provided in this application adopts the following technical solution:

[0007] A split-type base assembly, comprising:

[0008] First base;

[0009] A second base, wherein the second base and the first base are spaced apart to form a lateral distance; and

[0010] An adjustment seat, placed between the first base and the second base, is used to increase / decrease the lateral distance.

[0011] The adjustment seat is detachably connected to the first base and the second base.

[0012] By adopting the above technical solution, the entire base assembly is designed as a split unit. Utilizing a modular design approach, any base can be easily replaced to achieve combinations of different base sizes. Secondly, in practical applications, the dimensions of the switch module and controller are often standardized. The first and second bases can be used as fixed seats with unchanged dimensions. The adjusting seat is detachably connected between the first and second bases. By replacing the adjusting seat with different sizes, the lateral distance between the first and second bases can be adjusted, thus adapting to different installation conditions. Parts processing only requires corresponding machining of adjusting seats of different sizes, reducing manufacturing costs compared to machining the entire base.

[0013] Preferably, the adjustment seat includes:

[0014] The first body; and

[0015] The second seat has the same structure as the first seat and the two are arranged at intervals;

[0016] The first base, the second base, the first seat body, and the second seat body together form a hollow area.

[0017] By adopting the above technical solution, the split-type regulating seat further reduces manufacturing costs compared to the integral regulating seat. Secondly, the enclosed hollow area can provide space for wiring or external electrical components, giving the entire switchgear better installation flexibility.

[0018] Preferably, the first base includes two first side plates, the second base includes two second side plates, and the two ends of the first base and the second base are detachable from the first side plates and the second side plates.

[0019] By adopting the above technical solution, the first side plate and the second side plate can not only be connected to the first base and the second base, but also be used as crossbeams, thereby improving the connection strength and the integrity of the base assembly.

[0020] Preferably, it further includes a limiting structure for connecting the adjusting seat to the first base and the second base, the limiting structure comprising:

[0021] At least one limiting port is provided on the first side plate and the second side plate;

[0022] At least one positioning hole is provided on the first side plate and the second side plate;

[0023] The locking blocks are located at both ends of the adjusting seat and are engaged in the limiting port.

[0024] Limiting holes are provided at both ends of the adjusting seat, and the positioning holes correspond to and are connected to the limiting holes; and

[0025] The first fastener passes through the positioning hole and the limiting hole and is used to connect the adjusting seat with the first seat body and the second seat body.

[0026] By adopting the above technical solution, the locking block within the limiting port initially achieves the connection and positioning between the adjusting seat and the first and second bases, while simultaneously limiting the movement in one direction. The first fastener, after passing through the limiting hole and the positioning hole, further achieves connection limiting, facilitating installation while improving the reliability of the connection.

[0027] Preferably, both the first side plate and the second side plate have through openings.

[0028] By adopting the above technical solution, the opening facilitates the insertion of fingers when manually disassembling and assembling the switch device, providing a certain space for force application.

[0029] Preferably, it further includes an adjustment structure, the adjustment structure comprising:

[0030] Several first adjustment holes are provided on the outer side of the adjustment seat;

[0031] Several second adjustment holes are provided on the outer surfaces of the first base and the second base; and

[0032] The second fastener is used to connect the adjustment seat with the first base and the second base, and the second fastener passes through the first adjustment hole and the second adjustment hole;

[0033] The adjusting seat is slidably connected to the first base and / or the second base. When the adjusting seat slides relative to the first base and / or the second base, the lateral distance can be increased or decreased.

[0034] By adopting the above technical solution, the adjusting seat, as a component connecting the first base and the second base, can adjust the lateral distance between the first base and the second base when relative sliding occurs, thereby changing the size of the entire base assembly. After the adjusting seat completes the position adjustment relative to the first base and the second base, the adjusting seat is positioned and fixed to the first base and the second base by using a second fastener passing through the first adjustment hole and the second adjustment hole, realizing multi-level position adjustment.

[0035] Preferably, it further includes an adjustment structure, the adjustment structure comprising:

[0036] The first long opening is located on the outer side of the adjustment seat;

[0037] The second elongated opening is located on the outer sides of the first and second bases; and

[0038] The second fastener is used to connect the adjusting seat with the first base and the second base, and the second fastener passes through the first elongated opening and the second elongated opening.

[0039] The adjusting seat is slidably connected to the first base and / or the second base. When the adjusting seat slides relative to the first base and / or the second base, the lateral distance can be increased or decreased.

[0040] By adopting the above technical solution, the adjusting seat, as a component connecting the first base and the second base, can adjust the lateral distance between the first base and the second base when relative sliding occurs, thereby changing the size of the entire base assembly. After the adjusting seat completes the position adjustment relative to the first base and the second base, the adjusting seat is positioned and fixed to the first base and the second base by using a second fastener passing through the first and second elongated openings, realizing stepless position adjustment.

[0041] Preferably, the first base and / or the second base have guide grooves for the adjustment seat to slide.

[0042] By adopting the above technical solution, the guide groove design makes the sliding accuracy of the adjustment seat higher, which facilitates the improvement of the installation accuracy of electrical components.

[0043] Preferably, the first base and the second base further include a first mounting plate extending outward from one of its outer sides and a second mounting plate extending outward from the other outer side. The first mounting plate has mounting holes, and the second mounting plate has a mounting opening on one side.

[0044] By adopting the above technical solution, when the base assembly is connected to the cabinet, the mounting holes and fasteners cooperate to achieve initial positioning and connection. The mounting port facilitates the position adjustment of other fasteners. At the same time, one side of the mounting port is open, which facilitates the movement away from or towards the opening during the disassembly and assembly process to complete the separation or connection with the fasteners, thus achieving the effect of rapid installation.

[0045] In order to accommodate the installation of switching elements and controllers of different sizes and reduce manufacturing costs, the second objective of this application is to provide a dual power transfer switch device.

[0046] The split-type base assembly provided in this application adopts the following technical solution:

[0047] A dual-power transfer switch device includes a controller and a switch module, and also includes the aforementioned split-type base assembly, wherein the controller and the switch module are mounted on the split-type base assembly.

[0048] By adopting the above technical solution, the base assembly with a split structure can change the size of the entire base assembly by replacing the adjustment seat module. After manufacturing a spare size adjustment seat, it can be used for the installation of electrical modules of different switching devices, improving the flexibility of use and reducing manufacturing costs.

[0049] In summary, this application includes at least one of the following beneficial technical effects:

[0050] 1. By using a split base assembly structure, the size of the entire base assembly can be adjusted by changing different adjustment base sizes or by sliding the adjustment base relative to the first base and / or the second base. This makes it suitable for different types of switch modules, especially those with different wiring methods, and reduces the cost of manufacturing the entire base due to different installation size requirements.

[0051] 2. Through the split-type adjustment base structure, after connecting with the first base and the second base, it can form a hollow area, which further reduces the manufacturing cost while providing wiring space or installation space for connecting other electrical components.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example 1

[0068] Figure 1 A dual-power transfer switch device is shown. In this embodiment, the dual-power transfer switch device is an integral type, including a switch module 20 and a controller 30 that are electrically connected. The switch module 20 and the controller 30 are mounted on a base assembly 10. In this embodiment, taking the switch module 20 with a three-phase four-wire connection as an example, the overall length of the base assembly 10 is longer than the lateral dimension of the connection module and the controller 30.

[0069] The base assembly 10 includes a first base 11, an adjustment seat 12, and a second base 13. The adjustment seat 12 connects the first base 11 and the second base 13 through a limiting structure. The adjustment seat 12 is detachably connected to the first base 11 and the second base 13, so that the adjustment seat 12 of a pre-selected size can be replaced to change the overall length of the base assembly 10.

[0070] Combination Figure 2 and Figure 3 In this embodiment, the first base 11 and the second base 13 are of fixed size and are not used as replacement parts under normal disassembly and assembly conditions. The first base 11 includes two first side plates 111, and the limiting structure includes two limiting openings 40 and two positioning holes 50 that are spaced apart on the first side plate 111 on the same side.

The limiting structure also includes locking blocks 121 extending outward from both sides and limiting holes 122 opened on both sides. The locking blocks 121 can be engaged in the limiting openings 40. The number and position of the positioning holes 50 correspond to those of the limiting holes 122. When the adjusting seat 12 is connected to the first base 11 and the second base 13, the locking blocks 121 are engaged in the limiting openings 40 to achieve initial positioning. Subsequently, the first fastener passes through the limiting holes 122 and connects with the positioning holes 50.

[0073] In addition, to facilitate the installation of the entire switchgear, a first mounting plate 70 is provided on one outer side of the first base 11 and the second base 13, and a second mounting plate 80 is provided on the other outer side. The first mounting plate 70 has a mounting hole 71, and the second mounting plate 80 has a mounting opening 81 with one side opening. Fasteners can pass through the mounting hole 71 to connect with the cabinet, and the mounting opening 81 facilitates the quick insertion and removal of fasteners. Example 2

[0074] See Figure 4 A dual-power transfer switch device, differing from Embodiment 1, in that the adjusting seat 12 in the base assembly 10 can slide relative to the first base 11 and the second base 13. In this embodiment, guide grooves 14 are provided at the bottom of the first base 11 and the second base 13, and the side of the adjusting seat 12 can abut against the side wall of the guide groove 14 to achieve guided sliding.

[0075] The base assembly 10 also includes an adjustment structure, which includes several first adjustment holes 15, second adjustment holes 123, and a second fastener. The first adjustment holes 15 are formed on the two outer surfaces of the adjustment seat 12, and the second adjustment holes 123 are formed on the two outer surfaces of the first base 11 and the second base 13. When the adjustment seat 12 slides relative to the first base 11 and / or the second base 13, one of the first adjustment holes 15 can communicate with the second adjustment hole 123. The second fastener can be inserted into the first adjustment hole 15 and the second adjustment hole 123 to connect the adjustment seat 12 with the first base 11 and the second base 13, thereby adjusting the lateral distance between the first base 11 and the second base 13 and changing the overall length of the entire base assembly 10. Example 3

[0076] See Figure 5 A dual-power transfer switch device, differing from Embodiment 2 in that the adjustment mechanism includes a first elongated opening, a second elongated opening 124, and a second fastener. When the adjustment seat 12 slides relative to the first base 11 and / or the second base 13, the first elongated opening may partially overlap with the second elongated opening 124. The second fastener can be inserted into the first elongated opening and the second elongated opening 124 to connect the adjustment seat 12 with the first base 11 and the second base 13, thereby achieving stepless adjustment of the length of the base assembly 10.
