Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution cabinet that is easy to maintain. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits.

[0003] Patent CN219717581U discloses a power distribution cabinet that is easy to maintain. It includes a cabinet body and a cabinet door. The cabinet body includes a C-shaped fixed cabinet, a mounting plate for installing the power distribution unit, and two detachable side plates. The cabinet door is installed on the two side plates. The mounting plate is installed inside the fixed cabinet by bolts. The device divides the power distribution cabinet into a fixed cabinet body and two detachable side plates. An mounting plate for electrical installation is installed inside the fixed cabinet to facilitate wiring after electrical installation. The side plates and cabinet door can be removed to facilitate the maintenance of the installed electrical equipment and wiring.

[0004] However, this device directly mounts electronic components onto a single mounting plate. While maintenance personnel can maintain and inspect electronic components at the top of the mounting plate from a normal viewing angle, they face challenges when inspecting components at the bottom. Not only is the lighting poor in the bottom area, but maintenance personnel also need to crouch down to inspect them, increasing their workload and making it difficult to maintain a proper viewing angle. This negatively impacts the maintenance of the electrical cabinet. Therefore, a power distribution cabinet that is easier to maintain is proposed to address the problem of existing distribution cabinets being unable to conveniently inspect all electrical components.

[0014] Preferably, the limiting slider is fixedly connected to the bottom mounting plate, and there is a minimum frictional force between the limiting slider and the limiting groove that allows the bottom mounting plate to remain relatively stationary.

[0015] (III) Beneficial Effects

[0016] 1. This easily maintainable power distribution cabinet allows for easy maintenance of electronic components on the bottom mounting plate. By using the handle, the bottom mounting plate is moved to the right by the limiting plate within the limiting groove, until the limiting plate is fully inserted into the U-shaped adjusting seat. Then, a servo motor drives a screw to rotate, which, under the action of the sprocket and chain within the groove, moves the U-shaped adjusting seat and the limiting plate upwards. This position of the mounting plate is suitable for maintenance personnel, solving the problem of existing distribution cabinets having difficulty in conveniently maintaining all electrical components.

[0017] 2. This easy-to-maintain power distribution cabinet, by moving the bottom mounting plate to the right using the handle, allows the limiting plate to move into the U-shaped adjusting seat. During this process, the limiting slider in the limiting groove improves the stability of the mounting plate during forward and backward movement as well as up and down movement. In addition, the friction between the limiting slider and the limiting groove ensures the stability of the bottom mounting plate before it moves, thus improving the overall stability of this power distribution cabinet during use.

[0024] 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.

[0025] Example: Please refer to Figure 1-5A power distribution cabinet that is easy to maintain includes a cabinet body 1, a cabinet door 2 hinged to one side of the cabinet body 1, two mounting plates 3 inside the cabinet body 1, symmetrical limit grooves 4 at the bottom of the inner wall of the cabinet body 1, limit plates 5 slidably installed inside the limit grooves 4, handles 6 symmetrically and fixedly connected to one side of the bottom mounting plates 3, adjustment grooves 7 at both ends of the inner wall of the cabinet body 1, U-shaped adjustment seats 8 slidably installed inside the adjustment grooves 7, and a screw 9 penetrating through the inner cavity of the adjustment grooves 7, a servo motor 10 fixedly connected to the top of the cabinet body 1, and a groove 11 on the inner wall of the top of the cabinet body 1, with two sprockets 12 inside the groove 11 connected by a chain 13.

[0026] Furthermore, the bottom mounting plate 3 is fixedly connected to the limiting plate 5, and the width of the limiting plate 5 is the same as the width of the adjusting groove 7.

[0027] Furthermore, the output shaft of the servo motor 10 passes through the main body 1 of the power distribution cabinet and is fixedly connected to the screw 9. The screw 9 passes through the U-shaped adjusting seat 8 and the two are threadedly connected. The two sprockets 12 are fixedly connected to the screw 9 respectively.

[0028] Furthermore, a canopy 14 is provided on the top of the main body 1 of the power distribution cabinet. The canopy 14 shields the top of the main body 1 of the power distribution cabinet and the servo motor 10, thereby improving the protection effect of this power distribution cabinet that is easy to maintain.

[0029] Furthermore, two supplementary lights 15 are installed on the top of the inner cavity of the main body 1 of the power distribution cabinet. When inspecting electronic components or lines inside the main body 1 of the power distribution cabinet, the supplementary lights 15 are turned on. The supplementary light 15 on the right side can illuminate the electronic components and lines on the top mounting plate 3. When the bottom mounting plate 3 is moved to a suitable position, the supplementary light 15 on the right side can be used to illuminate the electronic components and lines on the moved mounting plate 3, further improving the convenience of inspecting the internal components or lines of this power distribution cabinet.

[0030] Furthermore, a limiting groove 16 is provided on the inner wall of the main body 1 of the power distribution cabinet, and two limiting sliders 17 are slidably arranged in the inner cavity of the limiting groove 16.

[0031] Furthermore, the limiting slider 17 is fixedly connected to the bottom mounting plate 3. There is a minimum frictional force between the limiting slider 17 and the limiting groove 16 that allows the bottom mounting plate 3 to remain relatively stationary. When the bottom mounting plate 3 is moved to the right by the handle 6, so that the limiting plate 5 is moved into the U-shaped adjusting seat 8, the limiting slider 17 in the limiting groove 16 works with the limiting slider 17 to improve the stability of the mounting plate 3 during forward and backward movement and up and down movement. In addition, the frictional force between the limiting slider 17 and the limiting groove 16 ensures the stability of the bottom mounting plate 3 before it moves, thus improving the overall stability of this power distribution cabinet during use.

[0032] Working principle: When using this easy-to-maintain power distribution cabinet, the necessary electronic components are installed on the mounting plate 3. When installing the electronic components on the bottom mounting plate 3, wiring is provided for the mounting plate 3 to move up and down. When it is necessary to inspect and maintain the electronic components on the bottom mounting plate 3, the bottom mounting plate 3 is moved to the right by the limit plate 5 in the limit groove 4 using the handle 6. The limit plate 5 is then moved until it is fully inserted into the U-shaped adjusting seat 8. Then, the servo motor 10 drives the screw 9 to rotate, thereby moving the screw 9 into the groove. Under the action of the sprocket 12 and chain 13 inside 11, the U-shaped adjusting seat 8 in the adjusting groove 7, together with the limiting plate 5, moves upward, making the position of the mounting plate 3 suitable for maintenance personnel to perform maintenance. This solves the problem that existing distribution cabinets are difficult to conveniently maintain all electrical components. After moving the bottom mounting plate 3 to a suitable maintenance position, the required maintenance tools can be placed on the limiting plate 5. This makes it easier to use different tools to maintain the electronic components or lines inside the main body of the distribution cabinet 1, avoiding the need for operators to repeatedly bend over to change tools and increase the burden on maintenance personnel.
