[0002] A low-voltage distribution cabinet refers to a combination assembled with one or more low-voltage switchgears and corresponding control, measurement signal, protection and other components, as well as all internal electrical and mechanical interconnections and structural components. The low-voltage distribution cabinet is a product used for converting and configuring electric energy. The rated current of the low-voltage distribution cabinet is 50Hz alternating current, and the rated voltage is 380V. The power distribution system is used as power, lighting and power conversion and control of power distribution.

[0003] In summary, the following loopholes still exist in the prior art:

[0004] ① In some hot areas, the annual temperature is above 35°C. In this environment, the heat dissipation function of the low-voltage distribution cabinet will decline, and the cooling fan needs to keep dissipating heat. Over time, the service life of the fan will decline. If the fan is always in a full-power output state, it will also waste electric energy;

[0005] ② At the same time, in rainy weather, the water level rises, causing outdoor low-voltage distribution cabinets to be flooded and unable to be protected in a short time, resulting in damage or short circuit of the distribution cabinets;

[0006] ③ The low-voltage distribution cabinet is heavy and inconvenient to move. The base of the low-voltage distribution cabinet is easy to rust when contacting with the humid ground, and it is very troublesome for maintenance personnel to repair and replace the base. Content of the Utility Model

[0007] In view of the deficiencies of the prior art, the utility model provides an intelligent low-voltage cabinet with automatic heat dissipation control to solve the above problems.

[0008] To achieve the above objectives, the utility model is realized through the following technical solutions.

[0013] Preferably, a filter screen is provided outside the heat dissipation holes to prevent dust from entering the low-voltage power distribution cabinet.

[0014] Preferably, the support device is composed of support legs and a baffle. The number of the support legs is four, which facilitates the support device to be more stable.

[0015] Preferably, the support leg includes an L-shaped support rod, an electric push rod, and a support pad.

[0020] Preferably, compared with the prior art, the present utility model discloses an intelligent low-voltage cabinet with automatic control of heat dissipation.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] An intelligent low-voltage cabinet with automatic cooling control includes a low-voltage power distribution cabinet 1 and a base 14. A solar power storage device is provided at the top of the low-voltage power distribution cabinet 1. A support device is provided outside the low-voltage power distribution cabinet 1. A heat dissipation mechanism is provided inside the low-voltage power distribution cabinet 1;

[0030] The solar power storage device includes a solar panel 2, a gear control box 3, a rack 4, a battery 5, an electric motor 6, and a moving mechanism 7. The solar panel 2 is connected to the moving mechanism 7. The moving mechanism 7 is arranged on the upper part of the gear control box 3. The gear control box 3 is provided with gears, a rack 4, and an electric motor 6. The electric motor 6 drives the gears to rotate. One end of the rack 4 is provided with a wear-resistant component and the wear-resistant component contacts the solar panel 2. The rack 4 meshes with the gears. The solar panel 2 is slowly pushed by the rack 4 and combined with the moving mechanism 7 to adjust the position of the solar panel 2 according to the moving trajectory of the sun at different times. For example, when the sun rises in the morning, the left solar panel 2 at the initial position is slowly pushed by the rack 4. At noon, when the sun is above the low-voltage power distribution cabinet 1, the moving mechanism 7 lifts the left and right solar panels 2 to be perpendicular to the ground at 90° to ensure that the solar panels 2 receive sufficient sunlight. When the sun sets at night, the rack 4 and the moving mechanism 7 return to the initial position. The electric energy collected by the solar panel 2 is stored in the battery 5. The stored electric energy of the battery 5 can provide electric energy for the fan 13. The solar power storage device can achieve the effect of energy saving;

[0031] The heat dissipation mechanism includes a temperature sensor 11, a fan 13, a base 14, and a cooling hole 16. The fan 13 is arranged on the top of the low-voltage power distribution cabinet 1. The temperature sensor 11 is arranged inside the low-voltage power distribution cabinet 1. The temperature sensor 11 is connected to the fan 13;

[0032] The implementation scenario is that after the baffle plate of the support device and the base 14 are installed with each other, the temperature alarm value is set for the temperature sensor 11 in advance. The temperature sensor 11 detects the temperature inside the low-voltage power distribution cabinet 1 in real time. When the temperature detected by the temperature sensor 11 is less than the alarm value, the fan 13 runs at low power at this time; when the temperature detected by the temperature sensor 11 is greater than the alarm value, the fan 13 runs at high power at this time, blowing the heat of the components inside the low-voltage power distribution cabinet 1 to the bottom of the low-voltage power distribution cabinet 1 and discharging the heat through the heat dissipation holes 16. The discharged heat will accumulate in the base 14, and the external power supply is used to drive the heat dissipation fan 15 to remove the heat accumulated in the base 14 to achieve the heat dissipation effect. Four small cylinders are provided in the base 14 to support the low-voltage power distribution cabinet 1, leaving a remaining space at the bottom of the low-voltage power distribution cabinet 1 to make the heat dissipation effect better. A water level detector is provided on the base 14, and the water level detector is connected to a power control module inside the low-voltage power distribution cabinet 1. When the water level detector detects that the water level has risen, the power control module controls the electric push rod 9 to lift to the highest height to reduce the loss of the low-voltage power distribution cabinet;

[0033] The support device is composed of support legs and a baffle plate. The number of support legs is four. The support legs include L-shaped support rods 8, electric push rods 9, and support pads 10. The L-shaped support rods 8 are installed on the left and right sides of the low-voltage power distribution cabinet 1. The electric push rods 9 are arranged inside the L-shaped support rods 8. The support pads 10 are fixedly arranged at the bottom of the electric push rods 9. A waterproof strip 12 is provided on the baffle plate to prevent water from entering the connection between the support device of the low-voltage power distribution cabinet and the base 14 when it rains outdoors;

[0034] The implementation scenario is that the surface of the base 14 has rusted after being stored on a wet ground for a long time and needs to be replaced. The electric push rod 9 is connected to the internal power supply of the low-voltage power distribution cabinet 1. The internal power supply of the low-voltage power distribution cabinet 1 drives the electric push rod 9. The electric push rod 9 lifts the entire cabinet through the support pad 10 and separates it from the base 14 to facilitate the replacement of the base 14.
