Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear technology, specifically a modular low-voltage switchgear. Background Technology

[0002] With technological advancements, safer equipment has been adopted in power systems to replace manual power operation, such as low-voltage switchgear. This allows for remote control and switching of power equipment. Typically, low-voltage switchgear is placed in a row or column in a distribution room. However, multiple switchgear units are interconnected, and they are prone to movement under external forces, leading to unstable connections. Therefore, splicing is necessary, necessitating the use of modular low-voltage switchgear.

[0003] Patent document CN222214881U discloses a modular low-voltage switchgear, comprising two low-voltage cabinets, a door panel, control buttons, a connecting block, a locking rod, a first locking slot, a second locking slot, and a limiting and fixing mechanism. The front side of the low-voltage cabinet is movably connected to the rear side of the door panel. The control buttons are located on the front side of the door panel. The bottom of the connecting block is fixedly connected to the right side of the top of the low-voltage cabinet, and the bottom of the locking rod is fixedly connected to the left side of the top of the low-voltage cabinet. The first locking slot is located on the surface of the locking rod, and the second locking slot is located on the surface of the connecting block. The limiting and fixing mechanism is located on the top and inside of the connecting block, and the second locking slot works in conjunction with the locking rod. This invention solves the problem that existing modular low-voltage switchgear requires users to manually rotate certain structures for assembly, which is cumbersome and inconvenient for users, especially when assembling taller low-voltage cabinets.

[0004] However, this low-voltage switchgear primarily relies on the external power grid for power supply during operation and lacks the capability for energy generation and optimized utilization. With the increasing prominence of global energy issues and rising electricity costs, relying solely on the power grid not only increases users' electricity costs but also contradicts the principles of sustainable development. Furthermore, in some remote areas or regions with unstable power supply, the low-voltage switchgear is significantly affected by grid fluctuations, making it impossible to guarantee a reliable power supply. Utility Model Content

[0005] The main purpose of this utility model is to provide a modular low-voltage switchgear that can effectively solve the problems of modularity and ensuring reliable power supply in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A modular low-voltage switchgear includes a cabinet A. Two limiting slide rails are installed on the right side of cabinet A. An I-beam is slidably connected inside the limiting slide rails. A cabinet B is fixedly connected to one side of the I-beam. Positioning holes are formed on the surfaces of both the limiting slide rails and the I-beam, and limiting mechanisms are inserted into the positioning holes. Solar panels are fixedly connected to the tops of both cabinet A and cabinet B.

[0008] The limiting mechanism includes a pin inserted into the positioning hole, a support spring sleeved on the surface of the pin, and a handle fixedly connected to the top of the support spring.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model, through the setting of limiting slide rails, I-beam blocks, and limiting mechanism, allows for the assembly of cabinets A and B. When assembling cabinets A and B, two I-beam blocks on one side of cabinet B are slid into the two limiting slide rails on the surface of cabinet A until the I-beam blocks slide to the appropriate position, causing the two positioning holes on the surface of the I-beam blocks and limiting slide rails to coincide. At this point, the stretched pin is released, and the pin is subjected to the reverse force provided by the support spring on one side, causing the pin to return to the starting position and insert into the limiting slide rails and I-beam blocks. This achieves the effect of limiting the assembled cabinets A and B, enabling rapid assembly of cabinets A and B and improving the installation efficiency of installers.

[0019] 2. This utility model, through the setting of a solar energy mechanism, can utilize two photovoltaic panels installed on the top of cabinet A and cabinet B to generate solar energy when used outdoors. The solar energy is converted into electrical energy and stored in a battery on one side. In conjunction with an inverter connected to the side of the battery, the electrical energy stored in the battery is converted into usable electrical energy to continuously power cabinet A and cabinet B, providing continuous and stable power support for the normal operation of cabinet A and cabinet B. This effectively solves the power supply problem in remote areas and ensures the normal operation of related equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a modular low-voltage switchgear, including a cabinet A1. Two limiting slide rails 2 are installed on the right side of the cabinet A1. I-beam blocks 3 are slidably connected inside the limiting slide rails 2. A cabinet B4 is fixedly connected to one side of the I-beam blocks 3. Positioning holes are opened on the surfaces of the limiting slide rails 2 and the I-beam blocks 3. Limiting mechanisms 5 are inserted into the positioning holes. Through the setting of the limiting slide rails 2, the I-beam blocks 3 and the limiting mechanisms 5, the effect of limiting the assembled cabinets A1 and B4 can be achieved, which can realize the rapid assembly of cabinets A1 and B4 and improve the installation efficiency of installers. Solar panels 6 are fixedly connected to the top of cabinets A1 and B4. Through the setting of the solar panels 6, a continuous and stable power support is provided for the normal operation of cabinets A1 and B4, effectively solving the power supply problem in remote areas and ensuring the normal operation of related equipment.

[0027] Please see Figure 2 The limiting mechanism 5 includes a pin 501 inserted into the positioning hole, a support spring 502 sleeved on the surface of the pin 501, and a handle 503 fixedly connected to the top of the support spring 502.

[0028] When assembling cabinets A1 and B4, the two I-beams 3 on one side of cabinet B4 are slid into the two limiting slide rails 2 on the surface of cabinet A1 until the I-beams 3 slide to the appropriate position, so that the two positioning holes on the surface of the limiting slide rails 2 coincide. At this time, the stretched pin 501 is released. The pin 501 is then subjected to the reverse force provided by the support spring 502 on one side, causing the pin 501 to return to the starting position and insert into the limiting slide rails 2 and the I-beams 3. This achieves the effect of limiting the assembled cabinets A1 and B4, enabling the rapid assembly of cabinets A1 and B4 and improving the installation efficiency of installers.

[0029] Please see Figure 3 The solar energy mechanism 6 includes a photovoltaic panel 601 fixedly connected to the top of cabinet A1 and cabinet B4. A controller 602 is electrically connected to one side of the photovoltaic panel 601 via a power line. A battery 603 is electrically connected to one side of the controller 602 via a power line. An inverter 604 is electrically connected to one side of the battery 603 via a power line.

[0030] When used outdoors, solar power can be generated using two photovoltaic panels 601 installed on the top of cabinets A1 and B4. The solar energy is converted into electrical energy and stored in a battery 603 on one side. In conjunction with an inverter 604 connected to the side of the battery 603, the electrical energy stored in the battery 603 is converted into usable electrical energy to continuously power cabinets A1 and B4. This provides continuous and stable power support for the normal operation of cabinets A1 and B4, effectively solving the power supply problem in remote areas and ensuring the normal operation of related equipment.

[0031] Please see Figure 1-4 The bottom of the support spring 502 is fixedly connected to the top of the limiting slide rail 2, and the top of the pin 501 is fixedly connected to the bottom of the handle 503; a support plate 7 is installed on the surface of the photovoltaic panel 601, and a support column 8 is fixedly connected to the bottom of the support plate 7. The support column 8 is fixedly connected to the top of cabinet A1 and cabinet B4; a fixed joint 9 is fixedly connected to the back of cabinet A1 and cabinet B4, and a support mechanism 10 is rotatably connected to the surface of the fixed joint 9; the support mechanism 10 includes a telescopic rod 1001 rotatably connected to the surface of the fixed joint 9, and the surface of the telescopic rod 1001... A fixed rod 1002 is slidably connected, and a rotating block 1003 is rotatably connected to the bottom of the fixed rod 1002. A positioning bolt 1004 is installed at the bottom of the rotating block 1003. Several threaded holes are opened on the surface of the telescopic rod 1001 and the fixed rod 1002. A threaded post 11 is threadedly connected inside one of the threaded holes. Four universal wheels 12 are installed in a rectangular array at the bottom of cabinet A1 and cabinet B4. Brake pads are installed inside the universal wheels 12. Heat dissipation holes are opened on both sides of cabinet A1 and cabinet B4. Dustproof nets 13 are installed inside the heat dissipation holes.

[0032] During installation, rotate the telescopic rod 1001 on the surface of the fixed joint 9 so that the telescopic rod 1001 and the bottom rotating block 1003 move to the appropriate position. Then, use the positioning bolts 1004 installed on the surface of the rotating block 1003 to fix the telescopic rod 1001, thereby achieving the effect of supporting cabinet A1 and cabinet B4 from the back.

[0033] Working principle: When assembling cabinet A1 and cabinet B4, the two I-beam blocks 3 on one side of cabinet B4 are slid into the two limiting slide rails 2 on the surface of cabinet A1 until the I-beam blocks 3 slide to the appropriate position, so that the two positioning holes on the surface of the I-beam blocks 3 and the limiting slide rails 2 coincide. At this time, the stretched pin 501 is released. The pin 501 is released and is subjected to the reverse force provided by the support spring 502 on one side, so that the pin 501 returns to the starting position and is inserted into the limiting slide rails 2 and the I-beam blocks 3.

[0034] When used outdoors, the two photovoltaic panels 601 installed on the top of cabinets A1 and B4 can generate solar power, converting solar energy into electrical energy and storing it in a battery 603 on one side. In conjunction with an inverter 604 connected to one side of the battery 603, the electrical energy stored in the battery 603 is converted into usable electrical energy to continuously power cabinets A1 and B4.
