[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the exhaust fan of this scheme is working, the external air is drawn in from the bottom of the shell, and then flows upward and is discharged from the air outlet, which can effectively utilize the principles of natural convection and gravity. Since hot air is lighter than cold air, the cold air enters from the bottom, and is heated by the heat source to form hot air, which naturally rises and is discharged, thereby achieving better heat dispersion and circulation, forming a reasonable air duct, which helps to reduce the risk of performance degradation, failure or damage of power equipment due to overheating and prolong its service life.

[0015] 2. The support column of this solution is located at the center of the shell, and several mounting frames are arranged in the shell, which can make greater use of space and reduce space waste. Compared with the traditional square box structure, the cylindrical structure of the shell reduces the floor space and reduces the manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-Figure 4 , the technical solution provided by this embodiment is as follows:

[0026] A distribution box comprises an outer shell 1, an inner wall of the outer shell 1 is fixedly connected with a partition 2, a box door 10 is rotatably connected inside the outer shell 1, a support column 3 is fixedly connected to the top of the partition 2, a plurality of mounting frames 4 are fixedly connected to the circumferential surface of the support column 3, a top cover 11 is fixedly connected to the top of the outer shell 1, a protective frame 5 is fixedly connected inside the top cover 11, and an exhaust fan 6 is installed inside the protective frame 5.

[0027] In a specific embodiment of the utility model, the shell 1 is a cylindrical structure, and a notch is arranged on the circumferential surface of the shell 1. The box door 10 can rotate in the shell 1. When the box door 10 and the shell 1 are closed, the notch can be sealed. The box door 10 can be opened to install line equipment, check various electrical components, etc. The support column 3 is located at the center of the shell 1, and the mounting frame 4 is fixed to the circumferential surface of the support column 3 by bolts. The adjacent mounting frames 4 are evenly distributed. A plurality of mounting frames 4 are arranged in the shell 1, which can make greater use of space and reduce space waste. Compared with the traditional square box structure, the cylindrical structure of the shell 1 is The floor space is reduced, the manufacturing cost is reduced, and an exhaust fan 6 is installed in the top cover 11. When the exhaust fan 6 is working, the external air is drawn in from the bottom of the shell 1, and then flows upward and is discharged from the air outlet 12, which can effectively utilize the principles of natural convection and gravity. Since hot air is lighter than cold air, cold air enters from the bottom, is heated by the heat source to form hot air, and naturally rises and is discharged, thereby achieving better heat dispersion and circulation, forming a reasonable air duct, and helping to reduce the risk of performance degradation, failure or damage of power equipment due to overheating, and extending the service life.

[0028] Specifically, air inlets 7 are provided on both sides of the bottom of the housing 1 , and first dustproof nets 8 are fixedly connected to the air inlets 7 .

[0029] In a specific embodiment of the utility model, when the exhaust fan 6 is working, external air enters the housing 1 through the air inlet 7. The design of the first dustproof net 8 can reduce the dust from entering the housing 1 and keep the housing 1 in a relatively clean state.

[0030] Specifically, a second dustproof net 9 is embedded in the bottom of the partition 2 .

[0031] In a specific embodiment of the utility model, the second dustproof net 9 is ventilated and further blocks dust from entering. The two-layer dustproof design greatly reduces the dust from entering the upper side of the partition 2, prevents dust from accumulating in the outer casing 1, and extends the service life of the power equipment. In addition, there is a certain distance between the partition 2 and the bottom of the outer casing 1, which increases the installation height of the support column 3 and plays a role in preventing waterlogging.

[0032] Specifically, the top cover 11 is of a conical structure, an air outlet 12 is provided at the bottom edge of the top cover 11 , and the top cover 11 is provided at the closing portion of the cabinet door 10 and the outer shell 1 .

[0033] In a specific embodiment of the utility model, the bottom diameter of the conical top cover 11 is larger than the outer shell 1, which can prevent rainwater from entering the outer shell 1 and improve the waterproof effect. The top cover 11 is a commonly used lock structure, which is used to fix the closed position of the box door 10, provide security, prevent unauthorized personnel from opening, and improve safety.

[0034] Working principle: When the exhaust fan 6 is working, it draws external air in from the bottom of the casing 1, and then flows upward and is discharged from the air outlet 12, which can effectively utilize the principles of natural convection and gravity. Since hot air is lighter than cold air, cold air enters from the bottom, and is heated by the heat source to form hot air, which naturally rises and is discharged, thereby achieving better heat dispersion and circulation, forming a reasonable air duct, which helps to reduce the risk of performance degradation, failure or damage of power equipment due to overheating and extend its service life.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
