Description

Technical Field

[0001] This utility model belongs to the field of cabinet technology and relates to a C-shaped switch cabinet. Background Technology

[0002] In the current field of power equipment, switchgear, as a crucial component of the power system, directly impacts the safe and stable operation of the power grid. However, traditional switchgear designs, particularly in dust and water resistance, have limitations that cannot be ignored. These limitations may not be apparent in normal environments, but in harsh industrial or natural environments, they become key factors affecting the service life and performance of switchgear.

[0003] Harsh environments, such as areas prone to sandstorms, coastal regions with extremely high humidity, or areas with severe industrial pollution, pose serious challenges to the protective capabilities of switchgear. Dust and moisture are pervasive invaders that can easily penetrate the interior of the switchgear, corroding the electrical components inside and causing serious problems such as poor contact, decreased insulation performance, and even short circuits. These problems not only affect the normal operation of the switchgear but may also create safety hazards and threaten the stability of the power system.

[0004] To address these challenges, traditional switchgear manufacturers typically employ several enhanced protection measures. A common approach is to use more expensive welded or spliced ​​profiles to construct the switchgear enclosure. These profiles offer high strength and sealing, providing a degree of protection against dust and moisture. However, this method is relatively expensive, increasing not only the manufacturing cost of the switchgear but also raising the barrier to entry for users.

[0005] Besides using high-performance profiles, traditional switchgear often enhances its protection level by adding double protective doors. The intention behind double protective doors is to create two lines of defense; even if the outer door is damaged or corroded, the inner door still provides additional protection. However, while this design improves protection, it also significantly increases the assembly difficulty of the switchgear. Installing double doors requires precise dimensional matching and rigorous sealing; even slight errors can lead to a decrease in sealing performance, thus affecting the overall protective effect.

[0006] Furthermore, traditional switchgear suffers from inconsistent strength during assembly. Due to the use of various materials and complex structural designs, the strength of the assembled switchgear is often difficult to maintain consistently. This instability not only affects the durability of the switchgear but also increases the risk of damage and deformation during transportation and installation. Once the switchgear is damaged or deformed during transportation, its protective performance will be significantly reduced, and it may even become unusable.

[0007] Furthermore, traditional switchgear represents a significant cost. High manufacturing costs, complex assembly processes, and susceptibility to damage and deformation all put traditional switchgear at a disadvantage in market competition. For users, choosing traditional switchgear means incurring higher procurement and maintenance costs, undoubtedly increasing their financial burden.

[0008] Therefore, how to reduce manufacturing costs, simplify the assembly process, and improve the durability and reliability of products while ensuring the protective performance of switchgear has become an urgent problem for switchgear manufacturers. Utility Model Content

[0009] In view of this, the purpose of this utility model is to provide a C-profile switch cabinet that, while meeting the requirements of frame structure and strength performance, reduces device cost, simplifies the assembly process, and upgrades the protection level to IP33 standard.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A C-shaped switch cabinet includes a rectangular frame, the frame including four uprights, and horizontal beams and vertical beams connected to the uprights, the vertical beams and horizontal beams being spaced apart at the ends of adjacent uprights;

[0012] The frame is provided with door panels and side panels at intervals along its circumference; wherein the door panels are located between adjacent columns connected by the crossbeams, and the side of the crossbeam closest to the door panels is bent against the column to form a waterproof eave.

[0013] A top cover is provided on the crossbeams and longitudinal beams located at the top of the frame, and a ventilation hood is also provided on the top cover;

[0014] The door panel has several ventilation holes, and each ventilation hole is equipped with a diamond-shaped mesh filter.

[0015] Optionally, the ventilation hood is provided with an outer eave at the top; the line connecting the cantilevered end of the outer eave and the bottom of the ventilation hole forms an angle of 60° with the outer eave.

[0016] Optionally, the four edges of the top cover are extended, protruding from the frame until they cover the door panel and side panel.

[0017] Optionally, each of the ventilation holes is provided with a downwardly sloping eave; the sloping angle of the eave is 55° to 65°.

[0018] Optionally, a sealing strip is also provided between the door panel and the frame.

[0019] Optionally, the door panel and the column on one side are rotatably connected by an externally fixed hinge.

[0020] Optionally, the door panel has an opening angle of at least 150°.

[0021] Optionally, the frame, side plates, top cover, and ventilation hood are connected by bolts.

[0022] Optionally, the side plate is provided with a plurality of indentation holes, and the bolt is installed in the indentation holes.

[0023] Optionally, the inner diameter of the rhomboid mesh is less than 2.5 mm.

[0024] The beneficial effects of this utility model are as follows:

[0025] This utility model's cabinet uses bolt connections, making assembly simple and convenient. It achieves an IP33 protection rating, preventing the intrusion of solid objects larger than 2.5mm in diameter and protecting against water spray within a 60-degree vertical angle. Overall, it offers excellent dust and water resistance. The frame profiles employ a modular design, produced with a 25mm module, satisfying the needs of various structural forms and adapting to different usage environments.

[0026] The frame undergoes roll forming and multi-folding edge processing, simplifying manufacturing and significantly improving structural strength and durability. Notably, waterproof eaves are installed on the crossbeams, downward-sloping eaves are provided above the ventilation holes, an outer eave is provided on the top of the ventilation hood, and the edges of the top cover extend and protrude beyond the cabinet frame to cover the edges of the door panels and side panels, all effectively preventing water splashing into the cabinet. The ventilation hood and ventilation holes ensure good ventilation. Sealing strips added to the edges of the door panels effectively enhance the seal between the door panels and the frame. The diamond-shaped filter screen inside the ventilation holes enhances dust prevention; the top cover strengthens its strength without increasing the cost of the sheet metal through multiple folding and welding techniques, solving the problem of edge vibration; the side panel fixing holes adopt a recessed process, which not only hides the bolt heads but also improves the tightness between the bolts and the sheet metal to enhance the product's sealing and aesthetics, while also dispersing the local pressure of the bolts on the sheet metal parts, effectively reducing stress concentration and ensuring product quality; the external fixed hinges not only allow the door panel to open and close to 150 degrees to adapt to different usage environments but also effectively reduce the gap between the door panel and the frame, thus significantly improving the overall protective capability of the cabinet.

[0046] Please see Figures 1-12 The present invention is a C-shaped switch cabinet, comprising a rectangular frame, the frame including four uprights 7, and crossbeams 5 and longitudinal beams 6 connected to the uprights 7, the longitudinal beams 6 and crossbeams 5 being spaced apart at the ends of adjacent uprights 7.

[0047] The frame is circumferentially spaced with door panels 3 and side panels 4. The door panels 3 are located between adjacent columns 7 connected by crossbeams 5. The side of the crossbeam 5 closest to the door panel 3 is bent against the column 7 to form a waterproof eave, effectively preventing water from splashing into the cabinet and facilitating the rapid drainage of accumulated water. The crossbeams 5, longitudinal beams 6, and column 7 profiles are all processed with roll forming and multi-folding edge technology, which simplifies processing and significantly improves structural strength and durability.

[0048] A top cover 2 is installed on the horizontal beam 5 and vertical beam 6 at the top of the frame, and a ventilation hood 1 is also installed on the top cover 2. The top of the ventilation hood 1 has an outer eave, and the line connecting the cantilevered end of the outer eave and the bottom of the ventilation hole 9 forms a 60° angle with the outer eave, forming a 60° waterproof zone. While ensuring good ventilation, this effectively prevents water dripping within the 60° range from directly penetrating the cabinet, resulting in excellent overall dustproof and waterproof performance. The frame profile adopts a modular design, produced with a 25mm module, which not only meets the needs of various structural forms but also adapts to the requirements of different usage environments. The four edges of the top cover 2 are extended, protruding from the cabinet frame until they cover the edges of the door panel 3 and side panel 4, preventing water dripping into the cabinet. Moreover, through multiple folding and welding techniques, its strength is enhanced without increasing the cost of the material, solving the problem of edge vibration.

[0049] The door panel 3 has several ventilation holes 9, each containing a diamond-shaped mesh filter with a mesh size of less than 2.5mm, further enhancing dustproof performance. Each ventilation hole 9 also features a downward-sloping eave with an angle of 55°–65°, preferably 60°. This ensures good ventilation while effectively preventing water dripping from 60° angles from directly entering the cabinet.

[0050] The door panel 3 and its side column 7 are rotatably connected by an externally fixed hinge 8. The opening and closing angle of the door panel 3 is at least 150° to adapt to the requirements of different usage environments and effectively reduce the gap between the door panel 3 and the frame, thereby significantly improving the overall protection capability of the cabinet. A sealing strip is also added to the edge of the door panel 3 to effectively enhance the sealing between the door panel 3 and the frame.

[0051] The frame, side plate 4, top cover 2, and ventilation hood 1 are connected by bolts; the side plate 4 is provided with several pressure holes 10, and the bolts are installed in the pressure holes 10.

[0052] The bolt fixing holes on side plate 4 employ a recessed design, which improves the rigidity and strength of the sheet metal and reduces deformation without increasing material thickness. The recessed holes 10 provide precise positioning for screws or bolts, ensuring accurate and stable installation. They also allow the screw or bolt heads to be flush with or slightly recessed from the sheet metal surface, enhancing the overall neatness of the appearance. This design not only conceals the bolt heads and improves the tightness between the bolts and the sheet metal for enhanced sealing and aesthetics, but also distributes the localized pressure of the bolts on the sheet metal, effectively reducing stress concentration and ensuring product quality.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
