An outdoor rain and snow prevention power distribution cabinet shown in fig. 1-4 comprises a top cover, a cabinet body, an exhaust device, support legs and support plates;
the top cover 1 is positioned at the uppermost part of the whole structure and comprises two gravity sensors 11 symmetrically arranged on the inner side wall and an electric heating resistance wire 12 arranged inside the top cover 1, and the gravity sensors 11 and the electric heating resistance wire 12 are electrically connected; when experiencing rainy and snowy weather, when snow appears at the top, the gravity sensor 11 senses weight change, transmits an electric signal for the electric heating resistance wire 12 through electric connection, and the electric heating resistance wire 12 heats and clears away the snow in time and effectively. The two symmetrically arranged gravity sensors 11 can effectively increase the sensitivity of the sensor, so that the device matched with the sensor can effectively react in time. Such setting can reduce the problem that the inside temperature of distribution cabinet that snow etc. brought is too low effectively to protect electrical components, prolong its life.
The cabinet body 2 is fixedly arranged below the top cover 1 and comprises cabinet doors 21 symmetrically arranged at the front side of the cabinet body, heat dissipation holes 22 correspondingly arranged at the left side wall and the right side wall of the cabinet body 2, temperature and humidity sensors 23 positioned at the upper end surface inside the cabinet body 2, a perspective window 24 arranged on the cabinet doors 21 and an illuminating lamp 25 fixedly arranged on the inner wall of the cabinet body 2; the temperature and humidity sensor 23 can timely detect the temperature and humidity in the cabinet, and transmits an electric signal to the exhaust device 3 matched with the temperature and humidity sensor to work, so that the dehumidifying and heat dissipating effects are achieved. The more optimized scheme is that a perspective window 24 is formed in the cabinet door, so that the purpose of facilitating the staff to check the daily working condition inside the distribution box is achieved; the illuminating lamp 25 arranged on the side wall in the cabinet body can meet the requirement of workers for inspection and maintenance at night or when the light is insufficient.
Further, the louvre 22 and the 2 lateral walls of the cabinet body between present 30 contained angles, can produce a large amount of heats in the block terminal working process, the hot-air of production rises, when the cooperation exhaust device 3 uses, the louvre 22 that the slope set up is discharged the heat more easily, has reduced the appearance that the heat piles up the condition. More preferably, the heat dissipation holes 22 are inclined by 30 degrees, so that the condition that rain and snow enter the distribution box in rainy and snowy weather can be effectively reduced, and the influence of the rainy and snowy weather on electrical components of the distribution box can be reduced.
The more optimized scheme is that a supporting plate 5 is arranged between the top cover 1 and the cabinet body 2, and a triangular structure is formed between the top cover 1 and the cabinet body 2 due to the arrangement of the supporting plate 5, so that the stability of the whole structure is ensured.
The four support legs 4 are fixedly arranged below the cabinet body 2 and symmetrically arranged, and the structural stability is improved due to the support legs 4; on the other hand prevents that whole distribution cabinet direct contact ground, especially when sleet weather, avoids its long-time wet environment of contact to produce the influence to the humidity of distribution cabinet internal environment to avoided electrical components life to reduce and produced the appearance of getting rusty, corruption scheduling problem easily.
The exhaust device 3 is fixedly arranged at the bottom of the cabinet body 2 and comprises a motor 31 fixedly arranged on the lower end surface of the cabinet body 2, an exhaust fan 32 connected below the motor 31 and a rotary opening and closing door 33 arranged below the exhaust fan 32; the arrangement that the exhaust device 3 is arranged at the bottom of the cabinet body 2 can effectively prevent rain and snow from entering the interior of the distribution cabinet in rainy and snowy weather, thereby reducing the occurrence of the conditions of electrical component damage and the like.
Further, the temperature and humidity sensor 23 is electrically connected with the air exhaust device 3; as shown in fig. 4, when the air discharge device 3 does not operate, the rotary opening/closing door 33 is in a closed state; because the distribution box can release larger heat in the work process, when the temperature and humidity sensor 23 senses that the temperature in the cabinet body is too high, an electric signal is transmitted to the exhaust device 3, the opening and closing door 33 is rotated to be opened, and the motor 31 drives the exhaust fan 32 to move until the internal temperature is restored to the set standard temperature value range; the more optimized scheme is that if a small amount of rain and snow enters the cabinet through the heat dissipation holes, in order to avoid influencing electrical components, when the temperature and humidity sensor 23 senses the change of humidity, the exhaust device 3 can work through the steps until the standard humidity value range is reached, and a good dehumidification effect is achieved. Therefore, the arrangement can keep relatively constant temperature and humidity environment inside the power distribution cabinet, and better protect internal electrical components, so that the power distribution cabinet keeps a stable working state.
The above embodiments are only for illustrating the technical concept and features of the present invention, and those skilled in the art can understand the contents of the present invention and implement the present invention, and the protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the technical scheme and technical concept of the present invention should be covered in the protection scope of the present invention.
