Description

Technical Field

[0001] This utility model relates to a power distribution cabinet, and more particularly to a typhoon-resistant outdoor cable junction box. Background Technology

[0002] Cable junction boxes are core outdoor and indoor equipment used in power distribution systems for connecting, splitting, branching, and switching cable lines. They mainly address the "line distribution" needs of high-voltage (10kV / 20kV / 35kV) or low-voltage (0.4kV) cables during transmission. They are widely used in urban power distribution networks, industrial parks, residential areas, remote mining areas, and other scenarios. They are key nodes for achieving efficient power transmission from main lines to branch lines or user terminals. Their core function is to replace traditional outdoor switch stations or distribution rooms, completing the "splitting" and "connection" of cable lines in a more compact and flexible manner.

[0003] Outdoor cable junction boxes in coastal areas need to be designed for normal use under extreme weather conditions, such as typhoons. Ensuring the safe operation of cable junction boxes and preventing damage to their core electrical components is a technical problem that those skilled in the art are constantly working to optimize and improve. Utility Model Content

[0004] To address the aforementioned issues, a typhoon-resistant outdoor cable junction box has been specially manufactured. This box is designed to withstand typhoon weather disasters and facilitates post-disaster equipment maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a typhoon-resistant outdoor cable junction box, comprising a cement base and a junction box body. The junction box body is mounted on the cement base and includes four steel columns, three sealing plates, and at least one door. The three sealing plates are positioned between two adjacent steel columns, and the door is positioned between the remaining two steel columns. A mounting base plate is also provided at the bottom of the sealing plates. The mounting base plate is positioned between two adjacent steel columns and has several mounting holes. Bolts are used to connect and install the junction box body to the cement base through the mounting holes.

[0006] Furthermore, the sealing plate includes an inner plate, a filling layer, and an outer plate. The inner plate is located inside the junction box body, the outer plate is located outside the junction box body, the filling layer is located between the inner plate and the outer plate, and the filling layer is a polyurethane buffer block. The outer plate is detachably installed on the steel column by bolts.

[0007] Furthermore, a cavity is provided between the filling layer and the mounting base plate, and reinforcing ribs are provided in the cavity.

[0008] Furthermore, the steel column has a hollow structure, with several hot air inlets located 10 to 40 centimeters from the top on the inner side of the steel column, and several hot air outlets located 10 to 40 centimeters from the bottom on the outer side of the steel column.

[0009] Furthermore, the surface of the steel column is also equipped with reinforcing cables, one end of which is connected to the steel column and the other end is embedded in the cement base.

[0010] Furthermore, the bottom of the steel column is an open structure, and a rainwater diversion channel is provided at the corresponding position of the cement base and the open structure. The rainwater diversion channel starts from the open structure and extends to the edge of the cement base.

[0011] The advantages of this utility model are: 1.

[0012] 2. The four steel columns provide support, which greatly enhances the overall strength of the junction box, making it less prone to deformation and damage.

[0013] 3. The junction box body is further reinforced with reinforcing cables to prevent the entire junction box body from being blown away by the typhoon.

[0014] 4. The steel column is equipped with a hot air upper vent and a hot air lower vent. Heat exchange can be achieved through the upper and lower vents to prevent the temperature inside the junction box from getting too high. At the same time, this upper and lower ventilation structure can also prevent rainwater from entering the junction box.

[0015] 5. The surface of the cement base is equipped with rainwater diversion channels, which can quickly divert rainwater to the outside of the steel column and the cement base in the event of heavy rain, preventing rainwater leakage and internal filling. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The typhoon-resistant outdoor cable junction box includes a cement base and a junction box body. The junction box body is mounted on the cement base and includes four steel columns, three sealing plates, and at least one door. The three sealing plates are positioned between two adjacent steel columns, and the door is positioned between the remaining two steel columns. A mounting base plate is also provided at the bottom of the sealing plates, positioned between two adjacent steel columns. The mounting base plate has several mounting holes through which bolts connect the junction box body to the cement base. The sealing plates include an inner plate, a filler layer, and an outer plate. The inner plate is located inside the junction box body, and the outer plate is located on the outside of the junction box body. The filler layer, which is a polyurethane buffer block, is located between the inner and outer plates. The outer plate is detachably mounted to the steel columns using bolts. A cavity is provided between the filler layer and the mounting base plate, and reinforcing ribs are provided in the cavity. The steel column has a hollow structure. Several hot air vents are located 10 to 40 cm from the top on the inner side of the column, and several hot air vents are located 10 to 40 cm from the bottom on the outer side. Reinforcing cables are also installed on the surface of the steel column, with one end connected to the column and the other end embedded in the concrete base. The bottom of the steel column is open, and a rainwater drainage channel is located at the corresponding point on the concrete base, extending from the opening towards the edge of the concrete base.

[0023] Its typhoon resistance is mainly reflected in several aspects: First, the junction box body is fixedly mounted on a concrete base using bolts. Installation nuts are pre-embedded in the concrete base at corresponding positions, and the junction box body is installed using rust-proof bolts, providing sufficient installation stability. One end of the reinforcing cable is connected to the junction box body, and the other end is embedded in the concrete base, further enhancing the junction box's typhoon resistance.

[0024] In addition, to cope with the impact of hard objects brought by typhoons, the sealing plate adopts a three-layer structure. The outer layer is made of detachable steel plate, which can withstand the impact of hard objects. Even if it is damaged by impact during a typhoon, only the outer plate needs to be replaced during subsequent maintenance, without affecting the normal operation of the junction box. The filling layer uses polyurethane buffer blocks, which can buffer the impact of hard objects caused by typhoons and protect the inner plate from damage.

[0025] Thirdly, the junction box is completely sealed to prevent rainwater from entering. However, to prevent the electrical components inside from overheating, hot air inlets and outlets are installed on the steel columns. This top-and-bottom heat exchange structure can prevent rainwater from entering while also meeting the heat dissipation requirements of the box. During typhoons, there may be short-term, extremely heavy rainfall. Some rainwater that enters the steel columns through the hot air outlets can be discharged through the rainwater drainage channel at the bottom of the steel columns.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this invention is defined by the appended claims rather than the foregoing description, and it is therefore intended to include all variations falling within the meaning and scope of the equivalents of the claims within this invention.
