Description

Technical Field

[0001] The utility model relates to a switch cabinet, specifically, to an easily maintainable switch cabinet. Background Art

[0002] A switch cabinet is an important electrical device in the power system, which is used for operations such as circuit control, protection, measurement, and regulation. It usually consists of a cabinet body, a cabinet door, and numerous electrical components installed inside the cabinet. To ensure the safe operation of the switch cabinet, maintenance personnel need to maintain it regularly. The maintenance contents include appearance inspection, internal cleaning, checking whether the electrical connection parts are tightened, checking whether the wires are damaged, aged, discolored, etc., and ensuring that the ventilation openings of the switch cabinet are unobstructed and the fans are running normally to ensure good heat dissipation effect.

[0003] In the existing fixed switch cabinet, each electrical component is installed on the back panel. When the cabinet door is opened, the staff can only observe the front of the electrical components, while most of the electrical connection parts and wires are located on the back of the electrical components, which is not conducive to observation. To save labor, the current in-factory specified maintenance method is to only check the front every month and conduct a comprehensive inspection every six months. At this time, the electrical components need to be disassembled or auxiliary tools are used to check the hidden parts, which leaves potential safety hazards to a certain extent.

[0004] To solve the above existing problems, people have been seeking an ideal technical solution. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide an easily maintainable switch cabinet with scientific design, convenient for observing the back of electrical components, more comprehensive inspection, and more efficient maintenance.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: an easily maintainable switch cabinet, including a cabinet body and a cabinet door. An element mounting rack is installed on the back panel of the cabinet body, and a number of electrical components are installed on the element mounting rack. Four observation mirror assemblies are installed on the back panel, and the four observation mirror assemblies surround the element mounting rack. The observation mirror assembly includes a long strip-shaped plane mirror extending along the border direction of the element mounting rack, and the long strip-shaped plane mirror is inclined towards the element mounting rack to facilitate observing the back situation.

[0007] Based on the above, the observation mirror assembly further includes a base, the base is installed on the back panel, a mounting shaft is arranged on the front of the base, a shaft sleeve is arranged on the back of the long strip-shaped plane mirror, the shaft sleeve is rotatably sleeved on the mounting shaft, and a locking bolt is arranged on the shaft sleeve corresponding to the mounting shaft.

[0008] Based on the above, the base includes an iron plate and a magnet adsorbed on the back of the iron plate. The mounting shaft is arranged on the front of the iron plate, and the iron plate is adsorbed on the back plate through the magnet.

[0009] Based on the above, the observation mirror assembly further includes a plurality of small round mirrors, and the backs of the plurality of small round mirrors are adsorbed on the mirror surface of the long strip-shaped plane mirror at intervals through suction cups.

[0010] Based on the above, the small round mirror is installed on the suction cup through an arbitrary stop hinge structure.

[0011] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0012] (1) By arranging the observation mirror assembly around the component mounting frame and tilting the long strip-shaped plane mirror towards the component mounting frame at a certain angle, through the reflection of light, the staff can observe the back side of the electrical component, thus facilitating the staff to conduct a comprehensive inspection and improving the maintenance efficiency and quality.

[0013] (2) The long strip-shaped plane mirror is installed on the mounting shaft through the bushing, which is convenient for adjusting its tilting angle to obtain a better observation angle, and the locking bolt is convenient for locking the angle.

[0014] (3) The base is adsorbed on the back plate through the magnet. On the one hand, it is convenient for installation, and on the other hand, it can be adsorbed at any position, which is convenient for avoiding the protruding parts in the cabinet.

[0015] (4) The plurality of small round mirrors are installed through an arbitrary stop hinge structure. During observation, the direction can be adjusted by rubbing with the operating rod, which is convenient for the staff to observe the doubtful parts more carefully. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the present utility model will be further described in detail through specific implementation manners below.

[0021] As Figures 1-3 shown, an easily maintainable switch cabinet includes a cabinet body 1 and a cabinet door 2. An element mounting rack 4 is installed on the back plate 3 of the cabinet body 1, and a plurality of electrical components 5 are installed on the element mounting rack 4. This part of the structure is a common switch cabinet structure in the market.

[0022] Four observation mirror assemblies 6 are installed on the back plate 3, and the four observation mirror assemblies 6 surround the element mounting rack 4. The observation mirror assembly 6 specifically includes a base and a long strip-shaped plane mirror 61. The base is installed on the back plate 3. An installation shaft 62 is arranged on the front surface of the base. A shaft sleeve 63 is arranged on the back surface of the long strip-shaped plane mirror 61. The shaft sleeve 63 is rotatably sleeved on the installation shaft 62. A locking bolt 64 is arranged on the shaft sleeve 63 corresponding to the installation shaft 62. The long strip-shaped plane mirror 61 extends along the border direction of the element mounting rack 4, and the long strip-shaped plane mirror 61 is inclined towards the element mounting rack 4. By rotating the shaft sleeve 63 around the installation shaft 62, the inclination angle can be adjusted to make the observation angle better, and finally it is locked with the locking bolt 64 to achieve angle locking. During subsequent maintenance, the back side of the electrical component 5 can be directly observed by using light reflection.

[0023] For convenient installation, the base includes an iron plate 65 and a magnet 66 adsorbed on the back of the iron plate 65. The installation shaft 62 is arranged on the front surface of the iron plate 65. The iron plate 65 is adsorbed on the back plate 3 through the magnet 66. This installation method can conveniently adjust the adsorption position of the magnet 66 or replace different specifications to conveniently avoid the protruding parts inside the cabinet body 1.

[0024] In order to conveniently observe the doubtful parts more carefully, the observation mirror assembly further includes three small round mirrors 67. The backs of the three small round mirrors 67 are adsorbed on the mirror surface of the long strip-shaped plane mirror 61 at intervals through suction cups 68. The small round mirrors 67 are installed on the suction cups 68 through an arbitrary stop ball hinge structure 69. The arbitrary stop ball hinge structure 69 specifically adopts a ball hinge that can be arbitrarily hovered in the prior art. It realizes arbitrary angle hovering by setting damping between the ball head and the ball groove, so as to conveniently observe the doubtful parts from multiple angles.

[0025] During actual use, first install the four observation mirror components 6 around the component mounting frame 4. During the initial installation, it is necessary to adjust the adsorption position of the magnet 66 and the inclination angle of the long strip-shaped plane mirror 61 so that the staff can observe the back side of the electrical component 5 while standing in front of the cabinet, and then lock it with the locking bolt 64. During subsequent maintenance, when the staff opens the cabinet door 1, they can not only observe the front side of the electrical component 5, but also observe the back side of the electrical component 5 through the long strip-shaped plane mirror 61. If the light in the cabinet 1 is insufficient, a flashlight can be used for illumination. When a doubtful part is found, the operating rod can be held by hand and the small round mirror 67 can be poked to change the angle, so as to observe the doubtful part more carefully.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features without departing from the spirit of the technical solutions of the present invention, and they should all be covered within the scope of the technical solutions claimed by the present invention.
