There are driving parts and control parts, and the driving parts are arranged inside the distribution box body 1, and the control parts are arranged inside and on the top of the distribution box body 1, the driving parts include a bidirectional motor 11, a worm 12 and a worm wheel 13, the inner cavity side wall of the distribution box body 1 is fixedly connected with the bidirectional motor 11 by bolts, one side of the bidirectional motor 11 is fixedly connected to the end of the connecting wire 15 away from the controller 14, the bidirectional motor 11 is fixedly connected with two groups of worms 12 through the output shaft, the ends of the two groups of worms 12 away from the bidirectional motor 11 are rotatably connected to the inner cavity side wall of the distribution box body 1 through the rotating shaft, the surfaces of the two groups of worms 12 are meshed and connected with the worm wheel 13, and the bottoms of the two groups of worm wheels 13 are fixedly connected with the top of the screw 7 by bolts;

[0020] By adopting the above technical scheme, the front sealing door 2 connected to the distribution box body 1 is rotated. In the process of ensuring its sealing, the front sealing door 2 is opened to facilitate the maintenance and inspection of the internal electrical equipment. At the same time, the monitoring feedback signal of the control component can be received through the controller 14 and the connecting wire 15, and corresponding commands can be issued to the control component and the driving component. When extreme weather such as heavy rain and strong wind occurs, the signal is received by the controller 14, and the bidirectional motor 11 can be used to output. The bidirectional motor 11 drives the worm 12 to rotate through the output shafts at both ends, so that the worm wheel 13 engaged with the worm 12 drives the two groups of lead screws 7 to rotate. The sealing plate 8 can be moved by the limiting effect of the two groups of sliding rods 6 on the sealing plate 8, so as to move to completely block the ventilation grille 3, seal the ventilation opening, and prevent dust and rain from entering the distribution box body 1.

[0021] Reference Figure 1 , Figure 2 and Figure 3 , the control components include an acoustic rain sensor 4, an ultrasonic wind speed sensor 5, a temperature sensor 9 and a fan 10. The top of the distribution box body 1 is fixedly connected with the acoustic rain sensor 4 by bolts, and the bottom of the acoustic rain sensor 4 is fixedly connected to the end of the connecting wire 15 away from the controller 14. An ultrasonic wind speed sensor 5 is provided on one side of the acoustic rain sensor 4. The bottom of the ultrasonic wind speed sensor 5 is fixedly connected to the top of the distribution box body 1 by bolts, and the bottom of the ultrasonic wind speed sensor 5 is fixedly connected to the end of the connecting wire 15 away from the controller 14. The inner cavity side wall of the distribution box body 1 is fixedly connected with the fan 10 by bolts, and the top of the fan 10 is fixed to the end of the connecting wire 15 away from the controller 14. The inner cavity side wall of the distribution box body 1 is fixedly connected with the temperature sensor 9 by bolts, and one side of the temperature sensor 9 is fixedly connected to the end of the connecting wire 15 away from the controller 14;

[0022] By adopting the above technical scheme, the size of external rainfall can be monitored through the sonic rain sensor 4, and the size of external wind can be monitored through the ultrasonic wind speed sensor 5. When strong winds or heavy rain occur, the signal can be quickly fed back to the controller 14 through the connecting wire 15. The controller 14 can use it to drive and control its related components, and the temperature inside the distribution box body 1 can be monitored through the temperature sensor 9. When the vents of the distribution box body 1 are sealed, it detects that the internal temperature is too high, which can be fed back to the controller 14 to immediately drive the fan 10. The fan 10 blows air to dissipate the heat of the internal electrical equipment first. At the same time, the temperature sensor 9, the sonic rain sensor 4 and the ultrasonic wind speed sensor 5 continue to monitor, and the monitored temperature and weather conditions are fed back to the controller 14 in time, so as to issue control commands to its related components in time.

[0023] The implementation principle of a sealed distribution box in the embodiment of the present application is as follows: the front sealing door 2 connected by the rotation of the distribution box body 1 can be opened to facilitate the maintenance and inspection of the internal electrical equipment while ensuring its sealing. The size of the external rainfall can be monitored by the acoustic rain sensor 4, and the size of the external wind force can be monitored by the ultrasonic wind speed sensor 5. When strong winds or heavy rain occur, the signal can be quickly fed back to the controller 14 through the connecting wire 15. The controller 14 receives its signal and issues a corresponding control command to its bidirectional motor 11, so that the bidirectional motor 11 can output. The bidirectional motor 11 drives the worm 12 to rotate through the output shafts at both ends of the bidirectional motor 11, thereby using the worm wheel 13 meshing with the worm 12 to drive the two sets of lead screws 7 to rotate, and the two sets of sliding The limiting effect of the movable rod 6 on the sealing plate 8 can move the sealing plate 8, so that it moves to completely block the ventilation grille 3 and seal the ventilation opening to prevent dust, rain and the like from entering the inside of the distribution box body 1. The temperature inside the distribution box body 1 can be monitored through the temperature sensor 9. When the ventilation opening of the distribution box body 1 is sealed, it detects that the internal temperature is too high and can be fed back to the controller 14 to immediately drive the fan 10. The fan 10 can blow air to dissipate the heat of the internal electrical equipment. At the same time, the temperature sensor 9, the sonic rain sensor 4 and the ultrasonic wind speed sensor 5 are continuously monitored, and the monitored temperature and weather conditions are fed back to the controller 14 in time, so that control commands are issued to its related components in time. The fan 10 can be selected from Arctic F8 PWM Rev.2, this fan 10 has a PWM speed regulation function, which can adjust the speed of the fan 10 as needed while maintaining relatively low noise. Its bidirectional motor 11 can use a NEMA 17 model dual-axis output stepper motor. Its working principle is based on electromagnetic induction. It generates a magnetic field by applying current to the electromagnetic coil, and then uses this magnetic field to interact with the permanent magnet inside the motor to drive the rotor to rotate. The stepper motor can accurately control the rotation angle and speed of each step, so it is very suitable for applications that require precise control. The acoustic rain sensor 4 can use the YL-83 model. The sensor emits sound waves, usually ultrasonic waves, through a built-in transmitter. These sound waves propagate in the atmosphere until they encounter rainfall. Once the emitted sound waves encounter raindrops, part of the sound waves will be reflected back to the sensor by the raindrops. The sensor's receiver receives the reflected sound waves and measures their propagation time or other characteristics. By analyzing the received reflected signals, the sensor can determine the distance between the raindrops and the sensor. Based on the strength and frequency of the reflected signals, the sensor can monitor the size and intensity of rainfall. The ultrasonic wind speed sensor 5 can be selected as the WLS70 model, which has an ultrasonic transmitter and a receiver inside the sensor.The transmitter emits ultrasonic pulses and the receiver receives these pulses. The emitted ultrasonic pulses propagate in the air until they encounter wind. When the ultrasonic wave encounters wind, the wind affects the ultrasonic wave, causing the propagation speed of the ultrasonic wave to change. The sensor measures the time required from the emission to the reception of the ultrasonic wave. Due to the influence of wind, the propagation time of ultrasound will be different for different wind speeds. According to the measured ultrasonic propagation time, the sensor can calculate and monitor the wind speed. The temperature sensor 9 can be selected from the DS18B20 model. The DS18B20 is a digital temperature sensor 9 that integrates a temperature sensor 9 and an analog-to-digital converter. The sensor contains a temperature sensor inside its chip, through which the ambient temperature can be measured. The sensor converts the temperature measurement result into a digital signal through the analog-to-digital converter inside the chip, so that its signal can be fed back to the controller 14. Similarly, its sonic rain sensor 4 and ultrasonic wind speed sensor 5 can both feed back their monitored signals to the controller 14 in a timely manner. The controller 14 can be selected from Arduino Uno. Arduino Uno is of moderate size and can be easily installed inside the distribution box body 1. Arduino Uno is an open source electronic prototyping platform with sufficient functions and flexibility to receive signals from multiple sensors and control multiple actuators. Arduino Uno has enough digital and analog input and output pins to connect to the DS18B20 digital temperature sensor9, WLS70 ultrasonic wind speed sensor5 and YL-83 acoustic rain sensor4. Programs can be quickly written to analyze sensor data and control NEMA 17 stepper motors and fans10. The NEMA 17 stepper motor can be controlled through digital output pins, and the speed of the fan10 can be controlled through PWM output. Using Arduino Uno as a controller14, corresponding programs can be written to receive and analyze sensor data and control its actuators, so that the NEMA 17 stepper motors can be controlled as needed. 17 stepper motors and fans 10 realize the monitoring of the temperature inside the distribution box body 1 and the external wind speed and rain and the control of related components. The overall operation is simple and easy to use. According to the external weather conditions, the ventilation holes of the distribution box can be immediately sealed to prevent dust or rain from entering the distribution box due to extreme weather conditions, affecting the normal operation of the internal electrical equipment and causing short-circuit damage. At the same time, during the sealing process, the internal temperature can be monitored and the corresponding heat dissipation components can be controlled and adjusted according to the internal temperature conditions, thereby preventing the internal temperature from being too high during the sealing process, causing damage to the internal electrical equipment.
