Description

Technical Field

[0001] This invention relates to the technical field of AC low-voltage distribution cabinets, specifically to an AC low-voltage distribution cabinet with a protective structure. Background Technology

[0002] AC low-voltage distribution cabinets are electrical devices used for distributing and controlling low-voltage AC power. They are widely used in power systems of industrial, commercial, and civil buildings. When AC low-voltage distribution cabinets are in operation, the electrical components inside (such as circuit breakers, contactors, busbars, etc.) generate heat. This heat needs to be dissipated in time, otherwise the component temperature will rise. The performance of electronic components will be affected when operating in a high-temperature environment. Heat dissipation holes are set on the surface of AC low-voltage distribution cabinets for internal heat dissipation. However, when heat dissipation is carried out through heat dissipation holes, dust, foreign objects, and small animals can enter the cabinet. Dust or foreign objects will adhere to the surface of electrical components, affecting their normal operation, while small animals may bite and break the internal cables.

[0003] To prevent foreign objects, dust, and small animals from entering, the ventilation holes on the surface of existing AC low-voltage distribution cabinets are relatively small. As a result, operators need to frequently clean the ventilation holes, which leads to a heavy workload for operators. If the holes are not cleaned in time, the heat dissipation of the entire cabinet will be affected, which will reduce the service life of the cabinet.

[0004] Meanwhile, when installing electrical components inside the cabinet, they are all directly installed on the inner wall of the cabinet. As the number of electrical components installed inside the cabinet increases, the operating space inside the cabinet becomes more and more limited. The narrow operating space not only makes it inconvenient for operators to move their hands and feet, resulting in slower installation speed and difficulty in accurately installing and wiring electrical components, but also easily leads to problems such as insecure installation and incorrect wiring. It also restricts the use of tools and increases the difficulty of installation. Summary of the Invention

[0005] The purpose of this invention is to provide an AC low-voltage distribution cabinet with a protective structure to solve the problems mentioned in the background art. Currently available AC low-voltage distribution cabinets have a small heat dissipation area, which can reduce the entry of dust and foreign objects, but requires frequent regular cleaning by staff. In addition, the operating space for operators is too limited when installing electrical components.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an AC low-voltage distribution cabinet with a protective structure, comprising a cabinet body, the top of which is configured as an open structure;

[0007] The sealing assembly is located on the outside of the cabinet and is used to engage with the outside of the cabinet to achieve the purpose of sealing the cabinet.

[0008] The installation components are arranged symmetrically in two sets inside the cabinet for the installation of electrical components.

[0009] The heat dissipation components are symmetrically arranged on both sides of the cabinet and are used to dissipate heat from inside the cabinet.

[0010] The installation assembly includes an installation mechanism and a protective mechanism, and the installation mechanism and the protective mechanism are arranged in an "L" shape.

[0011] Preferably, the cabinet includes an instrument compartment, a fixing plate, and a base plate. The fixing plate is installed on one side of the bottom of the instrument compartment, and the bottom of the fixing plate is integrally installed with the base plate. The instrument compartment, the fixing plate, and the base plate are arranged in a "U" shape.

[0012] Preferably, the sealing assembly includes a locking frame and a sealing plate. The locking frame is U-shaped and engages with the outside of the cabinet. The top of the locking frame is sealed by the sealing plate, and the two are fixed together by fastening bolts.

[0013] Preferably, ventilation holes are evenly distributed on the two side walls of the locking frame, and the top of the locking frame is engaged with the locking block at the top of the sealing plate.

[0014] Preferably, the mounting assembly includes a mounting frame and a connecting shaft. A slider is provided on the back of the mounting frame, and the slider slides in a groove on the inner wall of the fixing plate. A connecting shaft is fixed in the middle of the mounting frame, and the outside of the connecting shaft is connected to the mounting mechanism and the protective mechanism respectively.

[0015] Preferably, the mounting mechanism includes a mounting plate, and the surface of the mounting plate is uniformly provided with a mesh structure, on which electrical components are installed.

[0016] Preferably, the protective mechanism includes a protective plate, and heat dissipation holes are provided at equal intervals inside the protective plate, the cross-section of the heat dissipation holes being arranged in a "V" shape.

[0017] Preferably, the heat dissipation assembly includes a fixed frame, a heat dissipation fan, and a protective rod. The fixed frame is a hollow rectangular structure, and a "T"-shaped sliding block is integrally installed at its top. The sliding block slides in a reserved groove at the bottom of the instrument compartment, and the top of the instrument compartment and the reserved groove extends through the outermost part of the instrument compartment.

[0018] Preferably, the hollow structure in the middle of the fixed frame is provided with heat dissipation fans at equal intervals, and protective rods are provided on both sides of the outer side of the heat dissipation fans. The protective rods can be detached and installed from the fixed frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the AC low-voltage distribution cabinet with a protective structure;

[0020] 1. The largest possible ventilation opening on the frame provides sufficient airflow area to ensure rapid heat dissipation, effectively reducing the cabinet temperature. Combined with the "V"-shaped ventilation holes on the protective panel, this not only guides airflow and enhances natural convection, further improving heat dissipation efficiency, but also effectively prevents dust and small animals (such as mice and insects) from entering the cabinet, avoiding contact with live components and preventing short circuits or equipment damage. Furthermore, the large area of ​​the ventilation openings, combined with the V-shaped design, reduces the risk of blockage, thus decreasing the frequency of cleaning. This allows operators to dedicate more time and energy to other important maintenance tasks, improving overall maintenance efficiency.

[0021] 2. The entire installation and protective mechanism can rotate under the action of the connecting shaft. Therefore, during rotation, the position and angle of the mounting plate on the installation mechanism can be changed. This makes it easier for operators to access the components, reducing the risk of being scratched or bumped by sharp edges or protruding parts when moving in confined spaces. At the same time, it can also accurately install and wire electrical components, making it convenient for workers to operate and improving the flexibility of installation.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-7 The present invention provides a technical solution: an AC low-voltage distribution cabinet with a protective structure, including a cabinet body 1, the top of which is set as an open structure;

[0032] The sealing component 2 is disposed on the outside of the cabinet 1 and is used to engage with the outside of the cabinet 1 to achieve the purpose of sealing the cabinet 1.

[0033] Installation component 3, which has two sets symmetrically arranged inside the cabinet 1, is used for the installation of electrical components;

[0034] Heat dissipation components 4 are symmetrically arranged on both sides of the cabinet 1 and are used for heat dissipation inside the cabinet 1.

[0035] The installation component 3 includes an installation mechanism and a protective mechanism, and the installation mechanism and the protective mechanism are arranged in an "L" shape.

[0036] This application provides an AC low-voltage distribution cabinet with a protective mechanism. Specifically, in use, firstly, the entire cabinet 1 is set in a suitable position. Then, when electrical components need to be installed, the sealing component 2 needs to be separated from the cabinet 1. Then, the electrical components to be installed are installed on the mounting mechanism on the mounting component 3 to complete the installation. After the electrical components are installed, the sealing component 2 is locked to the cabinet 1 to complete the installation.

[0037] After installation, power on the entire distribution cabinet to enable normal operation. During normal operation, since the heat dissipation component 4 is located outside the protective structure, it ensures efficient heat dissipation of the distribution cabinet while preventing dust, impurities, and small animals from entering the cabinet 1 and damaging electrical components and cables. This extends the service life of the entire distribution cabinet.

[0038] Among them, according to Figure 1-4 As shown, the cabinet 1 includes an instrument compartment 11, a fixing plate 12 and a base plate 13. The fixing plate 12 is installed on one side of the bottom of the instrument compartment 11, and the bottom of the fixing plate 12 is integrally installed with the base plate 13. The instrument compartment 11, the fixing plate 12 and the base plate 13 are arranged in a "U" shape.

[0039] The sealing assembly 2 includes a locking frame 21 and a sealing plate 22. The locking frame 21 is U-shaped and engages with the outside of the cabinet 1. The top of the locking frame 21 is sealed by the sealing plate 22, and the two are fixed together by fastening bolts 23.

[0040] Ventilation holes 211 are evenly distributed on the two side walls of the locking frame 21, and the top of the locking frame 21 is engaged with the locking block 221 at the top of the sealing plate 22.

[0041] Specifically, when the sealing assembly 2 is engaged, the engaging frame 21 is engaged outside the fixing plate 12. After engagement, since the top of the engaging frame 21 protrudes from the fixing plate 12, the sealing plate 22 can be removed so that the engaging block 221 at its top engages with the top of the engaging frame 21. After engagement, the external fastening bolts 23 can be removed for fixation.

[0042] After the sealing component 2 is engaged with the cabinet 1, ventilation holes 211 are provided at the top and bottom of both sides of the engagement frame 21. Combined with the heat dissipation component 4 inside the cabinet 1, the purpose of efficient heat dissipation of the cabinet 1 can be achieved.

[0043] Furthermore, during installation, according to Figure 4-7 As shown, the mounting assembly 3 includes a mounting frame 31 and a connecting shaft 32. A slider is provided on the back of the mounting frame 31, and the slider slides in a groove on the inner wall of the fixing plate 12. The connecting shaft 32 is fixed in the middle of the mounting frame 31, and the outside of the connecting shaft 32 is connected to the mounting mechanism and the protective mechanism respectively.

[0044] The mounting mechanism includes a mounting plate 33, and the surface of the mounting plate 33 is uniformly provided with a mesh structure, on which electrical components are installed.

[0045] The protective mechanism includes a protective plate 34, and heat dissipation holes 341 are provided at equal intervals inside the protective plate 34. The cross-section of the heat dissipation holes 341 is arranged in a "V" shape.

[0046] Specifically, when installing electrical components, they can be directly installed on top of the mounting plate 33. When space is limited while the operator is installing on the mounting plate 33, the operator can control the mounting plate 33 to rotate around the connecting shaft 32. This allows the top of the mounting plate 33 to change angle towards the outside of the cabinet 1, thus facilitating the installation work. After the electrical components are installed, the connecting shaft 32 is rotated again, so that the mounting plate 33 is parallel to the fixed plate 12. At this time, the protective plate 34 is in a vertical state. When the locking frame 21 is engaged, the top of the protective plate 34 contacts the inner wall of the locking frame 21. Thus, the mounting plate 33 and the electrical components installed on it are all positioned in the middle of the cabinet 1, thereby achieving the purpose of protection.

[0047] In this application, the protective plate 34 is made of copper, which can conduct heat quickly. With the addition of the internal "V"-shaped heat dissipation holes 341, it can achieve efficient heat dissipation while protecting electrical components.

[0048] Furthermore, during heat dissipation, according to Figure 6 As shown, the heat dissipation assembly 4 includes a fixed frame 41, a heat dissipation fan 42, and a protective rod 43. The fixed frame 41 is a hollow rectangular structure, and a "T"-shaped sliding block 411 is integrally installed at its top. The sliding block 411 slides in the reserved sliding groove 111 at the bottom of the instrument chamber 11, and the top of the instrument chamber 11 and the reserved sliding groove 111 penetrate through the outermost side of the instrument chamber 11.

[0049] The fixed frame 41 has heat dissipation fans 42 arranged at equal intervals in the hollow structure in the middle, and protective rods 43 are provided on both sides of the outer side of the heat dissipation fans 42. The protective rods 43 can be detached and installed from the fixed frame 41.

[0050] Specifically, in this application, when the entire sealing assembly 2 is separated from the cabinet 1, and the operator needs to adjust the angle of the mounting plate 33 when installing or repairing electrical components, the entire fixing frame 41 can be manually pulled so that the sliding block 411 at its top slides inside the reserved sliding groove 111, thereby causing the entire fixing frame 41 to slide outward. Therefore, when the mounting plate 33 rotates and drives the protective plate 34 to rotate, the protective plate 34 has enough rotation space, and it is also convenient to disassemble and assemble the fixing frame 41 later.

[0051] After installation and maintenance, when heat dissipation is required, the DC motor at the top of the cooling fan 42 needs to be controlled to drive the cooling fan 42 to rotate, thereby achieving the purpose of heat dissipation inside the cabinet 1. During heat dissipation, the large area of ​​the ventilation holes 211 can ensure sufficient heat dissipation area. Combined with the heat dissipation holes 341 on the protective plate 34, efficient heat dissipation can be achieved. The contents not described in detail in this manual are existing technologies known to those skilled in the art.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
