Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a high and low voltage power distribution cabinet for easy maintenance in building construction. Background Technology

[0002] In building construction, high and low voltage switchgear are crucial equipment for power distribution and control. As the construction industry's requirements for the reliability and safety of electrical systems continue to increase, the design of switchgear is also constantly evolving. Traditional switchgear designs often involve tightly arranging multiple electrical components in the same vertical plane. While this design saves space, it brings many inconveniences during inspection and maintenance.

[0003] First, when electrical components are located on the same vertical plane, maintenance personnel often encounter tightly packed components during inspection, resulting in limited workspace and inconvenient operation. During inspection, personnel need to frequently disassemble and reassemble various components, increasing the complexity and time cost of the repair. Especially when a component needs to be inspected or replaced individually, it is often necessary to remove surrounding components one by one, which not only increases the difficulty of maintenance but may also damage other components during the process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high and low voltage distribution cabinet for easy maintenance in building construction. It has the advantage of separating each group of electrical components during maintenance, thus solving the problem of tightly arranging electrical components in the same vertical plane.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A high- and low-voltage distribution cabinet for easy maintenance in building construction includes a cabinet body and electrical components installed inside the cabinet body. A bracket is fixedly connected inside the cabinet body, and multiple support plates are provided on the bracket. The electrical components are installed on the support plates. The cabinet body is provided with a displacement mechanism for removing the electrical components. The displacement mechanism includes a load-bearing bar that is inclinedly and slidably installed on the bracket body via a sliding groove. The support plates are fixedly connected to the load-bearing bar. A frame body corresponding to the support plates is also fixedly connected to the bracket body. A plug is fixedly connected to the support plates. The frame body has a slot corresponding to the plug, and the plug is inserted into the slot to fix it. The frame body is also provided with a cable management component for winding and unwinding the lines when the electrical components are moved.

[0007] Preferably, the bottom of the insert block has a slot, a spring is fixedly connected to the frame, a block is fixedly connected to the end of the spring, the block is inserted into the slot, and a connecting rod is fixedly connected to the block for pulling the block out of the slot.

[0008] Preferably, a pull block is fixed to the end of the connecting rod, and the surface of the locking block facing the insertion block is arc-shaped.

[0009] Preferably, the cable management assembly includes a connecting shaft rotatably mounted between the load-bearing bars, a transmission wheel for winding the cable is fitted on the connecting shaft, a rack is obliquely mounted on the inner wall of the frame, and a spur gear that meshes with the rack is fixedly connected to the end of the connecting shaft.

[0010] Preferably, the end of the load-bearing bar is fixedly connected to a stop to prevent it from falling off, and the end of the connecting rod is fixedly connected to a pull block.

[0011] Preferably, the cabinet has a heat dissipation vent on the outside and a fault indicator light is installed on the cabinet.

[0012] By employing the above technical solution, this utility model provides a high- and low-voltage distribution cabinet for easy maintenance in building construction, which has at least the following beneficial effects:

[0013] 1. The high and low voltage distribution cabinets used in this building construction are designed for easy maintenance. By setting up a shifting mechanism, each group of electrical components can be moved individually to a downward angle during maintenance. This separates and misaligns the electrical components, reducing the risk of workers facing high-voltage equipment during maintenance and lowering the possibility of electric shock and other accidents.

[0014] 2. The high and low voltage distribution cabinets used in this building construction are easy to inspect and maintain. By setting up cable management components, the cables can always maintain a certain distance from electrical components. The fixed length of the cables makes it easier for maintenance personnel to operate when inspecting or maintaining electrical components, reducing interference caused by cable problems and improving work efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] In modern building construction, high and low voltage switchgear is crucial equipment for ensuring power supply and safe operation. With the increasing scale of buildings and the diversification of electrical equipment, the reliance on electrical systems is constantly growing. However, while traditional switchgear designs meet basic functional requirements, they often have shortcomings in terms of ease of inspection and maintenance, affecting construction efficiency and safety.

[0027] First, traditional high and low voltage switchgear designs typically place all electrical components in a compact space with a complex layout. This design forces maintenance personnel to operate in confined spaces, increasing the risk of accidents such as electric shock or equipment damage. Furthermore, the close arrangement of components often necessitates the disassembly of multiple surrounding components when replacing or maintaining a single component, increasing complexity and time consumption.

[0028] Example 1:

[0029] After prolonged operation, electrical components may experience aging and loosening of wiring and connections. Due to the lack of flexibility in traditional designs, maintenance personnel often struggle to conduct quick and effective routine inspections, leading to the failure to promptly detect and address potential faults. To address these issues, a new approach is needed, combining... Figures 1-4As shown, the present invention provides a high and low voltage distribution cabinet for easy maintenance in building construction, including a cabinet 100 and electrical components installed in the cabinet 100. A bracket 201 is fixedly connected inside the cabinet 100, and multiple support plates 202 are provided on the bracket 201. The electrical components are installed on the support plates 202. A displacement mechanism 200 for removing electrical components is provided inside the cabinet 100, which separates and misaligns the electrical components, thereby reducing the risk of workers facing high voltage equipment during maintenance and reducing the possibility of electric shock and other accidents.

[0030] Due to the lack of flexibility in traditional designs, maintenance personnel find it difficult to conduct quick and effective inspections during routine checks, resulting in the inability to detect and address potential faults in a timely manner. To solve this problem, the displacement mechanism 200 includes a load-bearing bar 203 that is slidably mounted on a bracket 201 via a slide groove. A support plate 202 is fixed to the load-bearing bar 203. A frame 205 corresponding to the support plate 202 is also fixed to the bracket 201. An insert block 206 is fixed to the support plate 202. A slot 207 corresponding to the insert block 206 is provided on the frame 205. The insert block 206 is inserted into the slot 207 to fix it. The insert block 206 is removed from the slot 207. Then, the load-bearing bar 203 slides diagonally downward along the slide groove on the bracket 201. During maintenance, each group of electrical components can be moved diagonally downward separately, making them misaligned with other groups of electrical components, which facilitates maintenance of the electrical components by the staff.

[0031] The movement of electrical components may cause tension on the wiring, resulting in physical damage to connection points, insulation materials, or conductors. To address this issue, the frame 205 is equipped with a wiring management assembly 300 for winding and unwinding wiring when electrical components are moved. When electrical components are moved, the wiring also moves with them. The wiring management assembly 300 ensures that electrical components remain at a fixed length during and after the movement, preventing tangling and tension. This reduces the risk of damage to the wiring due to excessive stress and improves the overall system reliability.

[0032] Specifically, the bottom of the plug 206 has a slot 209, and a spring 210 is fixed inside the frame 205. A locking block 208 is fixed to the end of the spring 210. The locking block 208 is inserted into the slot 209. A connecting rod 211 is fixed to the locking block 208 for pulling the locking block 208 out of the slot 209. After maintenance is completed, the electrical components need to be reset. The support plate 202 is pushed to move diagonally upward. The plug 206 on the support plate 202 is inserted into the slot 207. Then the spring 210 pushes the locking block 208 to insert it into the slot 207 to fix the plug. Then the support plate 202 can be fixed. The diagonally downward movement design makes full use of the internal space of the distribution cabinet and avoids affecting the flexibility of maintenance work due to the components being placed too tightly.

[0033] Furthermore, a pull block 212 is fixed to the end of the connecting rod 211. The surface of the locking block 208 facing the insertion block 206 is arc-shaped. The arc-shaped design allows the insertion block 206 to descend directly when it contacts the locking block 208. When the slot 209 and the locking block 208 are on the same vertical plane, the locking block 208 is inserted into the slot 209 to complete the fixation.

[0034] As can be seen from the embodiments, the staggered design allows maintenance personnel to more easily access and maintain or inspect electrical components, reducing maintenance time and labor costs.

[0035] Example 2:

[0036] Because electrical components need to be moved, the wiring needs to maintain a certain length. However, this can easily lead to tangling with surrounding wiring, making it difficult to quickly locate the corresponding wire. To solve these problems, a solution is needed... Figure 2 and Figure 5 As shown, based on Embodiment 1, a connecting shaft 302 is rotatably installed between the load-bearing bars 203. A transmission wheel 301 for winding the wire is mounted on the connecting shaft 302. A rack 303 is obliquely installed on the inner wall of the frame 205. A spur gear 304 that meshes with the rack 303 is fixedly connected to the end of the connecting shaft 302. As the transmission wheel 301 winds the wire, the movement of the load-bearing bars 203 drives the connecting shaft 302 to move. The spur gear 304 on the connecting shaft 302 rotates along the rack 303, causing the connecting shaft 302 to drive the transmission wheel 301 to rotate. This allows the wires on both sides of the transmission wheel 301 to be lengthened simultaneously, ensuring that the wires are always kept at a certain distance from electrical components. The fixed length of the wires makes it easier for maintenance personnel to operate when inspecting or maintaining electrical components, reducing interference caused by wire problems and improving work efficiency.

[0037] It can reduce unnecessary wear and damage, thereby extending the lifespan of wires and electrical components.

[0038] Specifically, the end of the load-bearing bar 203 is fixed with a stop block 204 to prevent it from falling off, and the end of the connecting rod 211 is fixed with a pull block 212. The pull block 212 is designed to facilitate the worker to pull the locking block 208 on the connecting rod 211 to move it out of the locking slot 209, so as to facilitate the movement of electrical components.

[0039] Furthermore, a heat dissipation vent 101 is provided on the outside of the cabinet 100, and a fault indicator light 102 is also installed on the cabinet 100.

[0040] As can be seen from the above embodiments: the worker first installs the electrical components on the support plate 202, and then connects the wiring. When maintenance is required, the worker pulls the locking block 208 on the connecting rod 211 to move it out of the locking slot 209, and the insertion block 206 moves out of the slot 207. Then the load-bearing bar 203 slides diagonally downward along the sliding groove on the bracket 201. During maintenance, each group of electrical components can be moved diagonally downward separately to make it misaligned with other groups of electrical components. Then the electrical components are maintained. After maintenance is completed, the electrical components are reset.
