Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Please refer to Figures 1 to 6 , Figure 1 A schematic diagram of a distribution box provided in an embodiment of the present invention, Figure 2 for Figure 1 Front view of the central distribution box. Figure 3 for Figure 1 Side view of the central distribution box. Figure 4 for Figure 1 Schematic diagram of the midsole plate.

[0028] The power distribution provided by the present invention includes a base plate 1, a distribution riser 2, a distribution element and a column housing 3. Among them, the base plate 1 is used to fix the distribution box, the distribution riser 2 is arranged perpendicular to the base plate 1, and the distribution elements are installed on both sides of the distribution riser 2 and are used to complete the conversion of the power supply of the external power supply into the required voltage for output. The arrangement of the distribution elements and the connection between them can refer to the prior art. The core of this application is to reduce the area of ​​the distribution riser 2 by arranging a specific number of distribution elements on both sides of the distribution riser 2, thereby significantly reducing the volume of the distribution box, and the column housing 3 protects the distribution riser 2 and the distribution elements. And through the detachable connection between the column housing 3 and the base plate 1, it is convenient to inspect and maintain the distribution elements fixed on the distribution riser 2.

[0029] The distribution box provided by the present invention is introduced in more detail below with reference to the accompanying drawings and specific embodiments.

[0030] In a specific embodiment provided by the present invention, the bottom plate 1 is a rectangular plate. In order to fix the bottom plate 1 and the power distribution riser 2, a strip-shaped positioning hole 101 is opened in the central position of the bottom plate 1. The power distribution riser 2 is a rectangular mounting plate. The bottom plate 1 and the power distribution riser 2 are fixed by plugging the power distribution riser 2 into the mounting hole of the bottom plate 1. In addition, the power distribution riser 2 can be fixed to the bottom plate 1 by welding or other methods as needed.

[0031] At the same time, the bottom plate 1 is also provided with a threading hole 102, which is convenient for the power supply of an external power source such as a power grid to be threaded into the distribution box and connected to the distribution components. The threading hole 102 can be set as a waist-shaped hole, a round hole or a rectangular hole, and the size of the opening can meet the threading of the power line. The threading hole 102 is specifically set as two groups, and the two groups of waist-shaped holes are symmetrically opened on both sides of the positioning hole 101.

[0032] In addition, the bottom plate 1 is also provided with mounting screw holes 103 that cooperate with the column housing 3. The mounting screw holes 103 are respectively provided at the periphery of the positioning hole 101 of the bottom plate 1 and the inner flange of the bottom of the column housing 3. By covering the column housing 3 at the periphery of the distribution riser 2, the mounting screw holes 103 provided on the bottom plate 1 are aligned with the mounting screw holes 103 provided on the column housing 3, and then connected and fixed by clevis bolts and washers. One advantage of using clevis bolts is that it is convenient to remove the column housing 3 by screwing it barehanded.

[0033] Furthermore, angle steel sheets 104 are provided at the four corners of the base plate 1, and the angle steel sheets 104 are welded vertically to the base plate 1. The angle steel sheets 104 at the four corners of the base plate 1 are used to fit and limit the four corners of the column shell 3, thereby improving the reliability of the installation of the column shell 3; when the column shell 3 is removed, the column shell 3 can also be temporarily erected and fixed on the angle steel sheets 104.

[0034] The distribution components include transformer 8, leakage protection switch 9, IoT module 11 and contactor 12. In order to fix multiple distribution components on the distribution riser 2, vertically extending distribution rails 201 are provided on both sides of the distribution riser 2. The distribution rails 201 are arranged like the rails of the back panel of the distribution box in the prior art. The distribution components are fixed by matching with the distribution rails 201. Figure 1 In the illustrated embodiment, the distribution element includes four transformers 8, three groups of air switches 10 and three groups of contactors 12 corresponding to the air switches 10. The specification of the contactor 12 is 20A, and the four groups of transformers 8 are symmetrically arranged on both sides of the top of the distribution stand 2. And the transformer 8, the leakage protection switch 9, the Internet of Things module 11, the air switch 10 and the contactor 12 are fixed on the distribution rail 201 in sequence from top to bottom. The Internet of Things module 11 is used to control the output on and off and output parameters of the distribution box through a mobile terminal, and may specifically include a 4G control module and a 5G control module. It should be noted that the distribution element itself and the connection of multiple distribution elements are not the core of this application, and their specific settings can refer to the prior art.

[0035] The above-mentioned multiple power distribution components can be installed and fixed not only through the vertically arranged power distribution rails 201, but also by opening a corresponding number of screw holes or welding installation grooves on the power distribution riser 2 to fix the power distribution components. The parameters and quantity of the power distribution components can be flexibly adjusted according to the power supply and distribution needs.

[0036] In order to convert the power output of the transformer 8 to meet the use requirements, the distribution box is also provided with a distribution output module 14, which includes a plurality of output modules such as a wiring board and a USB interface. The plurality of modules are respectively connected to transformers 8 of different specifications to meet different use requirements. The wiring board and the USB interface are embedded in the front of the column housing 3. Of course, as needed, the wiring board and the USB interface can also be fixed on the distribution stand 2 by opening an opening for the electric connector to pass through at the corresponding position of the column housing 3.

[0037] Since the above-mentioned distribution box can be installed and fixed on site, when it is fixed to the prefabricated bottom surface, the bottom plate 1 can be fixed to the bottom surface by anchor bolts. When it is used on soft ground in outdoor environments such as construction sites, embedded steel bars 13 are welded on the lower end surface of the bottom plate 1, and the bottom plate 1 is fixed to the ground by the embedded steel bars 13. Considering the moisture-proof factor when the distribution box is set on site, the fixed position of the distribution element is at least located above the distribution riser 2 at about 150 mm from the bottom plate 1. In other words, the lowest point of the distribution rail 201 and the screw holes or mounting slots used to fix the distribution element are all set above the distribution riser 2 at about 150 mm from the bottom plate 1.

[0038] In the specific implementation, in order to transmit the external power supply to the transformer 8 through the power line and reduce the winding of the wire in the column housing 3, a threading tube 4 is also provided in the column housing 3. The threading tube 4 extends vertically from bottom to top, and the bottom is the inlet end. An AMP connector is provided at the inlet end, which is connected to the external power supply through the cooperation of the AMP male and female connectors. The power line is threaded in the threading tube 4, reducing the risk of leakage. When the column housing 3 needs to be disassembled, it is only necessary to disconnect the AMP male and female connectors to connect the external power supply with the power line inside the column housing 3, and finally remove the column housing 3 as a whole. The threading tube 4 can be a plastic tube adhered to the inner wall of the column housing 3 by glue, or a metal tube can be welded and fixed to the inner wall of the column housing 3.

[0039] Considering the heat dissipation problem of the distribution box, a vent is particularly provided at the top of the column housing 3, and a cooling fan 5 is arranged at the vent. The surroundings of the cooling fan 5 and the vent wall, i.e., the column housing 3, are sealed with structural adhesive for waterproofing. The cooling fan 5 preferably adopts a waterproof fan. At the same time, in order to promote gas circulation, the column housing 3 also has ventilation louvers 302, which play a role in dustproof and ventilation. Generally speaking, the ventilation louvers 302 are provided on both sides of the bottom of the column housing 3, thereby forming a good air circulation. The cooling fan 5 is powered by a power cord extending from the wiring tube. When the column housing 3 is removed, the cooling fan 5, the column housing 3 and the threading tube 4 are removed from the bottom plate 1 as a whole. The column housing 3 can be removed by disconnecting the connection of the AMP male and female connectors under the wiring tube.

[0040] Furthermore, a rain cover cap 7 is provided above the column housing 3. The structure of the rain cover cap 7 can be referred to in the attached Figures 1 to 4 As shown, the inner side of the rain cover cap 7 and the outer side of the top of the column housing 3 are provided with mutually matching buckles to achieve snap connection and fixation, a ventilation hole is reserved between the supporting part of the rain cover cap 7 and the column housing 3 to ensure smooth air flow, and the top of the rain cover cap 7 forms a protection for the cooling fan 5 and the column housing 3. The buckle can be set as a ball buckle 301, and the ball buckle 301 is respectively set at the four corners of the column housing 3 and the four corners of the rain cover cap 7.

[0041] In a specific embodiment provided by the present invention, a temperature sensor 6 for detecting the temperature inside the column housing 3 is also provided in the column housing 3, and the temperature sensor 6 is connected to the cooling fan 5. When the temperature sensor 6 detects that the temperature inside the column housing 3 exceeds a preset value, such as 50°C, the cooling fan 5 is controlled to start running, which not only ensures that the temperature inside the column housing 3 does not exceed the temperature, but also saves electricity for the cooling fan 5. A humidity sensor can also be provided as needed, and when the humidity sensor detects that the humidity inside the column housing 3 is too high, the cooling fan 5 is started to promote air circulation. At this time, the temperature sensor 6 and the humidity sensor control circuit are arranged in parallel in the control circuit of the cooling fan 5. When any one of the start conditions of temperature and humidity is met, the cooling fan 5 circuit will be turned on and run to circulate the airflow. The structure and control of the temperature sensor 6 and the humidity sensor can refer to the prior art and will not be elaborated in detail here.

[0042] In the above embodiment, the size of the distribution box, that is, the size of the column housing 3, can be reduced to a cross-section of about 20cm*20cm, and by arranging distribution components on both sides of the distribution riser 2, the height of the distribution box can be reduced by about 1 times relative to the traditional distribution box, which significantly reduces the volume of the distribution box and improves the convenience of installation.

[0043] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0044] The above is a detailed introduction to the distribution box provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
