Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a safety power distribution cabinet. 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. They distribute electrical energy from a specific conductor in the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Furthermore, the power distribution cabinets on the market are divided into indoor power distribution cabinets and outdoor power distribution cabinets. Outdoor power distribution cabinets operate in the outdoor environment, which is relatively harsh. This makes the power distribution cabinets susceptible to moisture, dust, or other debris, which can cause short circuits or open circuits and lead to unnecessary losses.

[0004] In view of this, there is an urgent need for a safe distribution cabinet to solve the above problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safety-type power distribution cabinet includes: a cabinet body, a partition inside the cabinet body, an inner cavity above the partition, the opening of the inner cavity facing a horizontal side, an inner door and an outer door at the opening of the inner cavity, the outer door being located on the side of the inner door away from the inner cavity, and the same side of the inner door and the outer door being rotatably connected to the cabinet body.

[0008] Below the partition is an outer chamber with two openings: one facing away from the inner chamber and the other facing horizontally. The cabinet has a bottom door at the horizontal opening of the outer chamber, and one side of the bottom door is rotatably connected to the cabinet.

[0009] The partition is provided with several cable through holes.

[0010] The bottom door and the outer door are located on the same side of the cabinet.

[0011] The cabinet has an inner door frame at the opening of the inner cavity. One side of the inner door is rotatably connected to the inner door frame, and the inner door is adapted to the inner side of the inner door frame.

[0012] The cabinet has an outer door frame between the inner door frame and the outer door frame, and an annular sealing plate is provided on the side of the outer door frame away from the inner door frame.

[0013] The top of the cabinet is provided with a cabinet cover, and the top surface of the cabinet cover is in the shape of an inverted V.

[0014] The cabinet cover is provided with a ventilation cavity, which is in communication with the inner cavity. The cabinet cover protrudes circumferentially from the circumferential side of the cabinet body. The bottom of the cabinet cover is provided with a plurality of first ventilation holes, which are in communication with the ventilation cavity.

[0015] The first ventilation hole is rectangular, and the first ventilation holes are arranged side by side on the same side of the cabinet cover.

[0016] The cabinet has a second ventilation hole on both sides.

[0017] The cabinet is provided with a cover plate on the outside of the second ventilation hole, and the opening of the cover plate faces downward.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 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 should fall within the protection scope of the present invention.

[0026] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0027] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0028] like Figures 1-2 As shown, a safety-type power distribution cabinet includes: a cabinet body 1, a partition 2 disposed inside the cabinet body 1, and a partition 2 above the partition 2 (in this application, "above" refers to...). Figure 1 (In the direction indicated by the middle arrow) An inner cavity 3 is provided, and the opening of the inner cavity 3 faces the horizontal side. The cabinet 1 is provided with an inner door 4 and an outer door 5 at the opening of the inner cavity 3. The outer door 5 is located on the side of the inner door 4 away from the inner cavity 3. The same side of the inner door 4 and the outer door 5 is rotatably connected to the cabinet 1.

[0029] Below the partition 2, there is an outer chamber 6. The outer chamber 6 has two openings, one facing away from the inner chamber 3 and the other facing horizontally. The cabinet 1 has a bottom door 7 at the opening of the outer chamber 6 facing horizontally. One side of the bottom door 7 is rotatably connected to the cabinet 1.

[0030] The partition 2 has several cable through holes.

[0031] Based on the above structure, the relevant power distribution terminals and other components are all located inside the inner cavity 3. The inner door 4 and the outer door 5 provide double protection for the components inside the inner cavity 3, making it suitable for harsh outdoor environments. Furthermore, the external cable passes through the cable through hole from the bottom of the cabinet 1 (i.e., the bottom opening of the outer cavity 3) and enters the inner cavity 3. A ground door 7 is also provided to facilitate wiring. The fact that the cable passes through the inner cavity 3 from the bottom reduces the number of openings on the ring side of the cabinet 1 and improves the sealing performance of the ring side of the cabinet 1.

[0032] like Figure 1As shown, for ease of installation and operation, the bottom door 7 and the outer door 5 are located on the same side of the cabinet 1, making installation less restrictive.

[0033] like Figure 1 As shown, the cabinet 1 has an inner door frame 8 at the opening of the inner cavity 3. One side of the inner door 4 is rotatably connected to the inner door frame 8. The inner door 4 fits the inner side of the inner door frame 8 (a rubber gasket or similar material can be installed on the inner side of the inner door frame 8 to improve the sealing). In order to improve the sealing, a rectangular inner door frame 8 is set inside the cabinet 1 to install the inner door 4. When the inner door 4 is closed, it fits against the inner side of the inner door frame 8, which improves the sealing of the inner cavity 3.

[0034] like Figure 1 As shown, an outer door frame 9 is provided between the inner door frame 8 and the outer door 5 on the cabinet body 1. An annular sealing plate 10 is provided on the side of the outer door frame 9 away from the inner door frame 8. The outer door 5 is installed by setting the outer door frame 9, and the annular sealing plate 10 (which can be made of rubber or other materials) is provided on the outer door frame 9. When the outer door 5 is closed, the annular sealing plate 10 is placed between the outer door 5 and the outer door frame 9, which improves the sealing performance.

[0035] like Figures 1-3 As shown, the top of the cabinet 1 is provided with a cabinet cover 11. The top surface of the cabinet cover 11 is inverted V-shaped. The advantage of this design is that it can guide rainwater to both sides and prevent water from accumulating on the top of the cabinet.

[0036] like Figures 1-3 As shown, a ventilation cavity 12 is provided on the cabinet cover 11, which is connected to the inner chamber 3. The cabinet cover 11 protrudes circumferentially from the side of the cabinet 1. Several first ventilation holes 13 are provided at the bottom of the cabinet cover 11, and these first ventilation holes 13 are connected to the ventilation cavity 12. The advantage of this arrangement is that it allows the inner chamber 3 to be connected to the outside, increasing the airflow in the inner chamber 3 and improving the heat exchange efficiency. Furthermore, the first ventilation holes 13 face downwards, preventing rainwater and other foreign objects from entering the inner chamber 3. The first ventilation holes 13 are rectangular, and the first ventilation holes 13 located on the same side of the cabinet cover 11 are arranged side by side, thereby maximizing the number and size of the first ventilation holes 13 and improving the ventilation effect.

[0037] Further optimizations include, for example Figure 1 As shown, the cabinet 1 has second ventilation holes on both sides, and a cover plate 14 is provided on the outside of the second ventilation holes. The opening of the cover plate 14 faces downward, which further improves the ventilation of the inner cavity 3. The cover plate 14 also makes it difficult for rainwater and other foreign objects to enter the inner cavity 3.

[0038] like Figure 2As shown, an installation bracket 15 extending from top to bottom is provided in the inner cavity 3. By providing the installation bracket 15, it is convenient to install and position components such as wiring terminals, thereby improving the ease of installation.

[0039] In summary, all relevant power distribution terminals and other components are located inside the inner chamber 3. The inner door 4 and outer door 5 provide double protection for the components inside the inner chamber 3, making it suitable for harsh outdoor environments. Furthermore, external cables pass through the cable through-hole from the bottom of the cabinet 1 (i.e., the bottom opening of the outer chamber 3) into the inner chamber 3, and a ground door 7 is provided to facilitate wiring. The fact that the cables pass through the inner chamber 3 from the bottom reduces the number of openings on the side of the cabinet 1, improving the sealing of the side of the cabinet 1. As a result, the components inside the cabinet 1 are less susceptible to damage from moisture, dust, or other debris.

[0040] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
