Description

Technical Field

[0001] This utility model mainly relates to the field of electrical control cabinet technology, specifically to an electrical control cabinet that is easy to maintain. Background Technology

[0002] Electrical control cabinets need to be equipped with power switches, circuit breakers, controllers, relays, and overload protection devices. As the electrical control cabinet is used for a longer period of time, various faults may occur inside the cabinet, requiring timely maintenance and repair of the equipment installed inside.

[0003] Existing patent (publication number: CN208540296U) discloses an electrical control cabinet, including a cabinet body with doors on both the front and rear surfaces. The cabinet interior is divided into multiple installation sections by partitions. Inside the cabinet, a wiring groove is vertically located between the left and right side panels. A cross-shaped wiring rack is vertically located in the center of the cabinet. A fan is located on the top of the cabinet. The top panel and the left and right side panels are hollow structures and interconnected. Multiple ventilation holes are located in the inner layer of the left and right side panels, communicating with the hollow structures within the side panels. The fan is connected to the hollow structure in the top panel via a duct. The advantages of this invention are: the two doors facilitate the installation and maintenance of internal electrical equipment; the wiring grooves and wiring rack ensure neat and organized wiring between electrical devices, facilitating future maintenance.

[0004] In implementing the existing technical solution, the inventor found that the existing technology facilitates user maintenance by setting front and rear cabinet doors inside the cabinet. However, considering the actual installation and use environment of electrical control cabinets, it is usually necessary to fix the electrical control cabinet to the wall or the external frame structure of the designated equipment. In actual deployment, multiple cabinets are arranged and installed densely. It is necessary to consider whether there is any interference between the opening direction of the cabinet doors and the equipment in the installation area. Sufficient space needs to be reserved near the installation area of ​​the cabinet to facilitate workers to carry out maintenance work on the electrical equipment inside the cabinet. The double-door design of the cabinet is prone to technical problems such as inconvenience in maintenance work due to the limitations of the external installation environment during actual deployment.

[0036] See attached document Figure 1-4 This utility model provides an electrical control cabinet that is easy to maintain, comprising the following structure:

[0037] Cabinet 1, with an exhaust hood 2 and an air intake hood 3 fixedly installed at the top and bottom of the cabinet 1 respectively. A cabinet door 4 is movably hinged to the front side of the cabinet 1. Mounting sleeves 5 are fixedly installed on the left and right sides of the bottom of the cabinet door 4. A positioning bolt 51 is threadedly connected to the middle of the mounting sleeve 5.

[0038] Mounting plate 6 is symmetrically arranged on the left and right sides of the middle of cabinet 1. Multiple first connecting rods 61 are movably connected to the front end of mounting plate 6. The front part of the first connecting rod 61 is movably connected to the rear part of the second connecting rod 62. The front part of the second connecting rod 62 is movably connected to the outer side of auxiliary plate 63.

[0039] The first link 61 is connected to the second link 62 and is provided with a first damping rubber ring. The first link 61 is provided with a second damping rubber ring at the connection between the first link 61 and the mounting plate 6. The second link 62 is fixedly provided with a third damping rubber ring at the connection between the second link 62 and the auxiliary plate 63.

[0040] In this embodiment, cable trays 11 can be detachably attached to both the left and right sides of the cabinet 1. A vent is fixedly provided on the top left side of the cabinet 1. An exhaust port and an air inlet are fixedly provided on the top and bottom of the cabinet 1, respectively. The exhaust port is matched with the air inlet end of the exhaust hood 2, and the air inlet is matched with the exhaust end of the air inlet hood 3.

[0041] The cable tray 11 works with the cabinet 1 to facilitate the connection of cables into the cabinet 1 and to the electrical equipment mounted on the outside of the mounting bracket 7.

[0042] The ventilation port, exhaust port, and air inlet work together to facilitate the operation of the cooling fan 21 to provide air-cooled heat dissipation for the electrical equipment installed inside the cabinet 1.

[0043] In this embodiment, cooling fans 21 can be detachably snapped onto both the left and right sides of the top of the exhaust hood 2.

[0044] The exhaust hood 2 is designed to prevent large gaps between the cooling fan 21 and the cabinet 1 during assembly.

[0045] In this embodiment, an air intake filter element 31 is detachably snapped into the middle of the air intake shroud 3.

[0046] The air intake hood 3 and the air intake filter 31 work together to prevent external debris from entering the cabinet 1.

[0047] In this embodiment, a display screen 41 is detachably snapped onto the top of the cabinet door 4, and multiple operation buttons 42 are detachably snapped onto the surface of the cabinet door 4.

[0048] Cabinet door 4 serves as the mounting structure for display screen 41 and operation buttons 42. It can be opened at the front of cabinet body 1. The mounting sleeve 5 and positioning bolt 51 are provided on cabinet door 4. By adjusting the working position of positioning bolt 51 on mounting sleeve 5, the connection between positioning bolt 51 and auxiliary plate 63 is adjusted, pushing auxiliary plate 63 toward the rear side of the inner wall of cabinet body 1, or preventing auxiliary plate 63 from moving toward cabinet door 4 and causing electrical equipment to come into contact with the rear side of cabinet door 4.

[0049] When the electrical equipment inside the cabinet 1 has a high heat dissipation requirement, the auxiliary plate 63 can be pulled to move the electrical equipment on the mounting bracket 7 to the middle of the cabinet 1. At the same time, the positioning bolt 51 can be adjusted to restrict the forward movement of the auxiliary plate 63, so that the cooling fan 21 can dissipate heat from the electrical equipment.

[0050] In this embodiment, the front side of the auxiliary plate 63 is fixedly connected to the rear side of the mounting bracket 7. The surface of the mounting bracket 7 is provided with multiple mounting threaded holes. The length from the left end to the right end of the mounting bracket 7 is less than the length from the left to the right side of the hole that mates with the cabinet door 4 at the front of the cabinet body 1. The front side of the auxiliary plate 63 abuts against the rear end of the positioning bolt 51.

[0051] The installation of the first, second, and third damping rubber rings prevents the auxiliary plate 63 from becoming loose in its working position at the front of the mounting plate 6.

[0052] The auxiliary plate 63 and the mounting plate 6 are moved through the first link 61 and the second link 62. During the installation or maintenance of electrical equipment, the auxiliary plate 63 can be pulled toward the cabinet door 4 to move the mounting frame 7 and the electrical equipment mounted on it to the outside of the cabinet 1. When users perform installation and maintenance of electrical equipment, they are not restricted by the inner wall space of the cabinet 1, which makes it convenient for users to carry out maintenance work on electrical equipment in the electrical control cabinet.

[0053] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
