Technical Field
[0001] The present invention relates to the technical field of distribution cabinets, and more particularly to a waterproof distribution cabinet. Background Art
[0002] A distribution cabinet is a device widely used in the power system, mainly used for managing and allocating electric energy to ensure the normal, stable and safe power supply. In the power system, the distribution cabinet is responsible for receiving electric energy from the power source and distributing the electric energy to each electrical device or circuit through its internal circuits and various electrical components; at the same time, the distribution cabinet can also ensure the safety of electricity use, through overload protection, short-circuit protection, etc., to prevent equipment damage and safety accidents; the distribution cabinet plays an important role in the power system, ensuring the normal distribution of electric energy and the safe operation of equipment.
[0003] Due to the differences in the operating environment of the distribution cabinet, some distribution cabinets may also be used outdoors. After the distribution cabinet is used outdoors for a long time, slow water seepage may occur due to rainwater corrosion at the edge joints of the distribution cabinet body. If rainwater enters the interior of the distribution cabinet, it will affect the normal on-off of the internal circuit of the distribution cabinet, and even cause serious consequences such as short circuit and electrical fire; and after the rainwater enters the interior of the cabinet, it will also corrode various internal electrical components, weaken the strength and conductivity of metal parts, and shorten the service life of electrical components; however, the existing distribution cabinets do not have a good design for edge water seepage, so there is an urgent need for a waterproof distribution cabinet. Summary of the Invention
[0004] The purpose of the present invention is to solve the problems in the background art and provide a waterproof distribution cabinet.
[0005] The above technical object of the present invention is achieved through the following technical solutions: A waterproof distribution cabinet, comprising a support frame, a cabinet body and a base. The support frame is a main support mechanism arranged on the base. The cabinet body includes a plurality of mounting plates, and the mounting plates cover the outer periphery of the support frame to form the cabinet body; the support frame is formed by splicing and assembling a plurality of frame profiles, a connector is arranged between the frame profiles for splicing and fixing, and a waterproof kit is also installed at the connection of the frame profiles.
[0006] Preferably, the box-shaped profile is designed with a stepped structure, with a retaining edge provided on the outside. The ends of both sides of the retaining edge are set as angled bevels. A number of mounting plate fixing grooves for mounting the mounting plates of the cabinet body are also provided on the side surface of the retaining edge; on the side opposite to the retaining edge, a square connector mounting cavity is further provided. A number of connector locking holes for locking and mounting the connector are arrayed on the two side walls outside the connector mounting cavity. The groove formed between the connector mounting cavity and the retaining edge is a drainage groove; the support frame of the power distribution cabinet is assembled by using a number of box-shaped profiles of a specified length and splicing them through connectors. The box-shaped profile is designed with a square connector mounting cavity. Several reinforcing ribs of the connector can be locked and fixed by screws after being installed in the connector mounting cavity. The drainage groove between the connector mounting cavity and the retaining edge allows rainwater to flow out through the drainage groove and will not flow into the interior of the power distribution cabinet. Waterproof kits are also installed at both ends of the drainage groove, and the gaps formed between the box-shaped profiles during assembly can be sleeved inside. When rainwater passes through the drainage groove, it can flow out through the waterproof kit and will not flow into the interior through the gaps between the box-shaped profiles; mounting plate fixing grooves are provided on the box-shaped profile, and the mounting plates of the cabinet body are locked and fixed on the box-shaped profile by screws and T-shaped fixing blocks. Compared with the traditional welding method for installing the cabinet body plates, using screws for locking and installation can make the later maintenance and replacement of the cabinet more convenient.
[0007] Preferably, the connector includes triangular ribs and connecting ribs. The triangular ribs are provided with three ribs in different directions, including two mounting ribs and one support rib. Connector threaded holes corresponding to the connector locking holes are provided on the peripheral side walls of both mounting ribs. Connector threaded holes are also provided on the peripheral side walls of the connecting rib; the box-shaped profile can be locked and installed on the ribs in different directions of the connector by screws; the triangular ribs and connecting ribs of the connector can be respectively connected to box-shaped profiles in different directions, and the box-shaped profile is locked and installed on the connector through the connector threaded holes on the peripheral side walls of the mounting ribs. The connector realizes the connection of each box-shaped profile. The support frame formed by connecting through the connector avoids the use of traditional welding methods for manufacturing, making the flexibility of the cabinet body better. During maintenance and replacement, the power distribution cabinet can be disassembled and installed more conveniently, improving the maintenance efficiency of the cabinet body. At the same time, compared with the welding joints when using connectors for connection, the strength provided can be higher, enabling the power distribution cabinet to bear a greater load and having better quality.

By adjusting the positions of the fixers, the position of the electrical mounting plate can be adjusted. During actual use, the front and rear positions of the electrical mounting plate can be adjusted according to actual needs, which can make the installation of electrical components more flexible. At the same time, it can also make the power distribution cabinet bear a greater load and higher strength without affecting the support frame and the cabinet body.
[0014] Preferably, a square mounting post is provided on the mounting plate placer.

[0019] The present invention will be described in detail below with reference to the accompanying drawings by way of examples.
[0020] Example
[0021] According to Figures 1 to 4As shown in the figure, a waterproof power distribution cabinet includes a support frame body 1, a cabinet body 2, and a base 3. The support frame body 1, which is the main support mechanism, is arranged on the base 3. The cabinet body 2 includes a number of mounting plates, and the mounting plates are wrapped around the outer periphery of the support frame body 1 to form the cabinet body 2. The support frame body 1 is formed by splicing and assembling a number of frame-shaped profiles 10. A connector 11 is provided between the frame-shaped profiles 10 for splicing and fixing, and a waterproof kit 12 is also installed at the connection of the frame-shaped profiles 10.
[0022] According to Figure 2 、 Figure 3 As shown in the figure, the frame-shaped profile 10 is designed with a stepped structure. A baffle 101 is provided on the outside, and the ends of both ends of the baffle 101 are set as beveled edges with angles. A number of mounting plate fixing grooves 102 for mounting the mounting plates of the cabinet body 2 are also opened on the side surface of the baffle 101. A square connector installation cavity 103 is also provided on the side opposite to the baffle 101. A number of connector locking holes 104 for locking and installing the connector 11 are arranged in an array on the two side walls outside the connector installation cavity 103. The groove formed between the connector installation cavity 103 and the baffle 101 is a drainage groove 105. The support frame body 1 of the power distribution cabinet is formed by splicing and assembling a number of frame-shaped profiles 10 of a specified length through the connector 11. The frame-shaped profile 10 is designed with a square connector installation cavity 103. Several reinforcing ribs of the connector 11 can be locked and fixed by screws after being installed in the connector installation cavity 103. The rainwater can flow out through the drainage groove 105 between the connector installation cavity 103 and the baffle 101 and will not flow into the interior of the power distribution cabinet. Waterproof kits 12 are also installed at both ends of the drainage groove 105, and the gap formed by assembling the frame-shaped profiles 10 with each other can be sleeved inside. When the rainwater passes through the drainage groove 105, it can flow out through the waterproof kit 12 and will not flow into the interior through the gap between the frame-shaped profiles 10. Mounting plate fixing grooves 102 are opened on the frame-shaped profile 10, and the mounting plates of the cabinet body 2 are locked and fixed on the frame-shaped profile 10 by screws and T-shaped fixing blocks 26. Compared with the traditional welding installation of the cabinet body plates, using screws for locking and installation can be more convenient for the later maintenance and replacement of the cabinet body 2.
[0023] According to Figure 3As shown, the connector 11 includes triangular ribs 111 and connecting ribs 112. The triangular ribs 111 are provided with three ribs in different directions, including two mounting ribs 1111 and one support rib 1112. Connector threaded holes 113 corresponding to the connector locking holes 104 are provided on the peripheral side walls of the two mounting ribs 1111. Connector threaded holes 113 are also provided on the peripheral side walls of the connecting rib 112. The frame-shaped profile 10 can be tightly installed on the ribs in different directions of the connector 11 through screws; the triangular ribs 111 and the connecting ribs 112 of the connector 11 can be respectively connected to the frame-shaped profiles 10 in different directions, and the frame-shaped profile 10 is tightly installed on the connector 11 through the connector threaded holes 113 on the peripheral side walls of the mounting ribs 1111. The connector 11 realizes the connection of each frame-shaped profile 10. The support frame 1 formed by connecting through the connector 11 avoids the use of traditional welding methods for production, making the power distribution cabinet more flexible. During maintenance and replacement, the power distribution cabinet can be disassembled and installed more conveniently, improving the maintenance efficiency of the power distribution cabinet. At the same time, compared with the welding joints when using the connector 11 for connection, it can provide higher strength, enabling the power distribution cabinet to bear greater loads and having better quality.
[0024] According to Figure 4 As shown, the connection part of the three ribs of the triangular rib 111 is the triangular rib thickening part 1113. The thickness of the triangular rib thickening part 1113 is thicker than the thickness of the two mounting ribs 1111 and the support rib 1112; a connecting rib installation groove 1114 is provided on the end face of the triangular rib thickening part 1113, and the connecting rib 112 is installed in the connecting rib installation groove 1114; a connecting screw installation hole 1115 is provided on the other end face of the triangular rib thickening part 1113, and the connecting rib 112 is tightly installed in the connecting rib installation groove 1114 through screws; the triangular rib thickening part 1113 is located at the intersection of the three ribs. After the connector 11 connects and assembles each frame-shaped profile 10, most of the external forces received by the power distribution cabinet will be transmitted to the triangular rib thickening part 1113 of the connector 11. When the thickness of the triangular rib thickening part 1113 is thicker than the thickness of other ribs, the strength of the connector 11 can be higher, enabling the connector 11 to bear higher loads and making the power distribution cabinet have higher strength and better stability during actual use.

The kit edge 122 is also designed with an inclined edge, and the angle of the inclined edge is the same as the angle of the inclined edge at the end of the edge 101; there will be a certain gap formed after the frame-shaped profiles 10 are assembled with each other. These gaps will allow rainwater to flow into the interior of the power distribution cabinet through these gaps, thereby affecting the normal operation of the circuits and electrical components inside the cabinet 2. The waterproof kit 12 is wrapped around the gaps formed by the assembly of the frame-shaped profiles 10. The waterproof kit 12 wraps the entire gap inside. When the rainwater flows through the diversion groove 105 and then passes through the gap, it will flow to the bottom of the support frame 1 and be discharged after passing through the diversion groove 124 on the waterproof kit 12, and will not enter the interior of the power distribution cabinet. This not only ensures the normal use of the circuits inside the power distribution cabinet but also guarantees the personal and property safety of the operators of the power distribution cabinet, greatly improving the stability and safety of the use of the power distribution cabinet.
