DETAILED DESCRIPTION

[0034] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] An intelligent power distribution cabinet with circuit breaker warning function, such as Figure 1-Figure 5As shown, it includes a power distribution cabinet body 1, and a rapid cooling device 4 is arranged on the upper part of the interior of the power distribution cabinet body 1. The rapid cooling device 4 includes a temperature sensor 41, a semiconductor refrigeration plate 45 and a sealed cavity 44. The front and rear sides of the power distribution cabinet body 1 are both provided with a first ventilation hole 42 and a second ventilation hole 43. The top of the semiconductor refrigeration plate 45 is provided with a heat dissipation fin 46, and the top center of the power distribution cabinet body 1 is provided with a first screen 47; a servo motor 5 is arranged on one side of the power distribution cabinet body 1, and a rotating shaft 6 is arranged at the output end of the servo motor 5. A sleeve 7 is sleeved on the outer side of the rotating shaft 6, and a fan blade 8 is arranged on the sleeve 7. The setting of the rapid cooling device 4 enables the power distribution cabinet body 1 to respond in time when the temperature rises abnormally, and start cooling measures to ensure the safety of the equipment and extend the service life. The combination of the servo motor 5 and the rotating shaft 6, the sleeve 7, and the fan blade 8 accelerates the air flow rate and assists the rapid flow of air near the cold end of the semiconductor refrigeration plate 45, thereby realizing rapid cooling of the inside of the power distribution cabinet body 1 and the heat dissipation fin 46.

[0038] See also Figure 3 The temperature sensor 41 and the semiconductor refrigeration plate 45 are both separately connected to an external independent power supply. The cold end of the semiconductor refrigeration plate 45 is set downward, and the hot end of the semiconductor refrigeration plate 45 is set upward. The separate connection of the temperature sensor 41 and the semiconductor refrigeration plate 45 to the external independent power supply ensures that when an abnormality occurs in the distribution cabinet body 1, the rapid cooling device 4 can work independently of the main power supply, thereby improving the reliability of the system. The cold end of the semiconductor refrigeration plate 45 is set downward, and the hot end is set upward, and gravity is used to assist the natural convection of cold and hot air, thereby enhancing the cooling effect.

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 The sealed cavity 44 is made of heat-insulating material, and is tightly connected to the main body 1 of the power distribution cabinet. The sealed cavity 44 is made of heat-insulating material, and is tightly connected to the main body 1 of the power distribution cabinet, which effectively isolates the external high temperature, keeps the internal temperature stable, and improves the cooling efficiency. At the same time, it ensures that the cold air flow reduces the loss when it flows through the sealed cavity 44 through the first ventilation hole 42, and ensures that the cold air flow can better maintain the temperature, and dissipates heat to the heat dissipating fins 46 through the second ventilation hole 43.

[0040] See also Figure 3 , Figure 4 , Figure 5There are two groups of first ventilation holes 42 and second ventilation holes 43, each group of first ventilation holes 42 and second ventilation holes 43 has multiple first ventilation holes 42 and second ventilation holes 43, and the multiple first ventilation holes 42 and second ventilation holes 43 are evenly and equidistantly distributed. The two groups of symmetrically arranged first ventilation holes 42 and second ventilation holes 43 can ensure that cold air can cool down the heat dissipating fins 46 from the first ventilation holes 42 and second ventilation holes 43 on both sides. The multiple evenly and equidistantly distributed first ventilation holes 42 and second ventilation holes 43 can allow cold air to pass through the two evenly, thereby ensuring that the heat dissipating fins 46 at different positions are effectively cooled.

[0041] See also Figure 3 , Figure 4 , Figure 5 The first ventilation hole 42 is connected with the space below the semiconductor refrigeration plate 45 and the sealed cavity 44, and the second ventilation hole 43 is connected with the space above the semiconductor refrigeration plate 45 and the sealed cavity 44. The connection between the first ventilation hole 42 and the space below the semiconductor refrigeration plate 45 and the sealed cavity 44, and the connection between the second ventilation hole 43 and the space above the semiconductor refrigeration plate 45 and the sealed cavity 44 form an effective heat exchange path, promote the exchange of cold and hot air, and improve the cooling efficiency. With the assistance of the rotating fan blades 8, part of the cold air is forced to pass through the first ventilation holes 42, the second ventilation holes 43 and the sealed cavity 44 and into the upper space where the heat dissipation fins 46 are located.

[0042] See also Figure 3 , Figure 5 The heat sink 46 is tightly fitted with the hot end of the semiconductor refrigeration plate 45. The heat sink 46 is made of aluminum-magnesium alloy, which has excellent thermal conductivity, as well as the advantages of light weight and high strength. It is tightly fitted with the hot end of the semiconductor refrigeration plate 45, ensuring that heat can be smoothly transferred from the hot end of the semiconductor refrigeration plate 45 to the heat sink 46, thereby effectively improving the heat dissipation efficiency.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The servo motor 5 is fixedly connected to the rotating shaft 6, the rotating shaft 6 is rotatably connected to the distribution cabinet body 1, the sleeve 7 is fixedly connected to the rotating shaft 6, and the fan blade 8 is fixedly connected to the sleeve 7. When the servo motor 5 is started, it drives the rotating shaft 6 fixedly connected to it to rotate, so that the sleeve 7 and the fan blade 8 fixed on the rotating shaft 6 rotate smoothly. The fixed connection between the servo motor 5 and the rotating shaft 6, and the rotatable connection between the rotating shaft 6 and the distribution cabinet body 1 ensure the stability and reliability of the fan blade 8 and improve the efficiency of air flow.

[0044] See also Figure 3There are multiple groups of sleeves 7 and fan blades 8, and each group of sleeves 7 and fan blades 8 are evenly and equidistantly distributed. The evenly and equidistant distribution of multiple groups of sleeves 7 and fan blades 8 optimizes the wind force distribution, improves the uniformity of air flow and the cooling effect. When the servo motor 5 is started and drives the fan blades 8 to rotate smoothly, multiple fan blades 8 rotate at the same time, forcing the air at multiple positions to participate in convection.

[0045] Embodiment 2:

[0046] See also Figure 1 , Figure 2 , Figure 3 , heat dissipation grooves 2 are opened on both sides of the distribution cabinet body 1, and a second screen 9 is arranged at the heat dissipation groove 2. A rain cover 3 is arranged above the heat dissipation groove 2. The setting of the heat dissipation groove 2, in conjunction with the second screen 9 and the rain cover 3, can effectively prevent the intrusion of impurities and rainwater while ensuring the heat dissipation efficiency, thereby protecting the distribution cabinet body 1. The opening of the heat dissipation groove 2 can meet the daily heat dissipation needs of the distribution cabinet body 1, and when the distribution cabinet body 1 is dissipating heat daily, no additional energy consumption will be generated to drive the heat dissipation.

[0047] See also Figure 1 , Figure 2 , Figure 3 There are two groups of heat dissipation slots 2, each group of heat dissipation slots 2 has multiple heat dissipation slots, and the multiple heat dissipation slots 2 are evenly and equidistantly distributed. The two groups of heat dissipation slots 2 are symmetrically arranged, so that air can dissipate heat through the heat dissipation slots 2 on both sides at the same time, ensuring the heat dissipation effect. The design of evenly and equidistantly distributed heat dissipation slots 2 increases the heat dissipation area, improves the heat dissipation efficiency, and helps to maintain a stable operating temperature of the distribution cabinet body 1.

[0048] The implementation principle of the utility model is as follows: first, the heat generated during the normal use of the distribution cabinet body 1 will be dissipated through the heat dissipation slots 2 on both sides, impurities in the air will be effectively intercepted by the second screen 9, and rainwater will be intercepted by the rain cover 3; when the distribution cabinet body 1 is in use, due to the high external environment temperature, aging of equipment, inaccurate installation of parts resulting in increased contact resistance, and the operating overload has not reached the rated value and the circuit breaker has not been started, etc., resulting in an abnormal increase in the temperature inside the distribution cabinet body 1, the temperature sensor 41 detects the abnormal temperature change and starts the semiconductor refrigeration plate 45 and the servo motor 5 through an external independent power supply. By using the Peltier effect, the cold end of the semiconductor refrigeration plate 45 absorbs heat, so that the air temperature above the distribution cabinet body 1 is reduced; at the same time, the servo motor 5 is started to drive the rotating shaft 6 rotates, thereby causing the sleeve 7 and the fan blade 8 thereon to rotate, accelerating the air flow rate above the power distribution cabinet body 1, so that the cold air circulates and cools down with other positions inside the power distribution cabinet body 1 as soon as possible; then, after part of the cold air moves to the first ventilation hole 42, it smoothly passes through the sealed cavity 44 and the second ventilation hole 43, and enters the space where the heat dissipation fins 46 on the top of the hot end of the semiconductor refrigeration plate 45 are located, assisting the hot end of the semiconductor refrigeration plate 45 to cool down, so as to ensure that the cold end of the semiconductor refrigeration plate 45 can continue to cool; after the corresponding maintenance personnel find that the independent power supply and the corresponding rapid cooling device 4 are started, before the maintenance is completed, the rapid cooling device 4 ensures that the temperature inside the power distribution cabinet body 1 does not rise to the limit, thereby protecting the power distribution cabinet body 1 to a certain extent and extending its service life to a certain extent.
