If the distribution cabinet is placed in an outdoor environment, rainwater can easily enter the cabinet through the bellows in rainy weather, which can easily damage the electrical components in the cabinet. Therefore, a power distribution cabinet with remote access control is proposed. Utility Model Content

[0019] 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.
[0020] See also Figure 1-3 In this embodiment, a power distribution cabinet capable of remote access control includes a cabinet body 1, a rain shield component is installed on the top of the cabinet body 1, and a heat dissipation mechanism is installed on the cabinet body 1.
[0021] The rain shield assembly includes a rain shield 2, and columns 4 are fixed on the left and right sides of the inner top wall of the rain shield 2, and fixed tubes 13 are fixed on the left and right sides of the top of the cabinet 1, and the columns 4 are inserted into the interior of the fixed tube 13. An I-shaped plate 15 is fixed on one side of the fixed tube 13, and two limit rods 17 are slidably connected inside the I-shaped plate 15. An annular block 19 is fixed to the outside of the limit rod 17, and a spring 18 is sleeved on the outside of the limit rod 17. One end of the limit rod 17 close to the fixed tube 13 passes through the fixed tube 13 and is inserted into the interior of the limit groove 14. A pull rod 16 is fixed on the side of the two limit rods 17 away from the fixed tube 13. The spring 18 is in contact between the I-shaped plate 15 and the annular block 19, and the annular block 19 is in contact with the outer wall of the fixed tube 13. The setting of the annular block 19 enables the annular block 19 to compress the spring 18 when the limit rod 17 moves.
[0022] Among them, by setting up a rain shield component, inserting the column into the fixed tube and limiting the column by inserting the limiting rod into the limiting groove, the rain shield can be installed on the top of the cabinet and the air inlet box can be covered inside, and the rain shield is blocked above the heat dissipation hole, which can prevent rainwater from easily entering the cabinet on rainy days without affecting the heat dissipation effect.
[0023] It should be noted that the rain shield 2 can block the air inlet box 3 and the cabinet body 1, thereby achieving the effect of shielding rain and preventing rainwater from easily entering the cabinet body 1 through the air inlet box 3 on rainy days. When the rain shield 2 is damaged, pulling the pull rod 16 drives the limit rod 17 to move to one side of the I-type plate 15, so that the limit rod 17 can be pulled out of the limit groove 14, thereby facilitating the replacement and installation of the rain shield 2.
[0024] In this embodiment, the heat dissipation mechanism includes an air inlet box 3, which is embedded and fixed on the top of the cabinet 1. A cooling fan 6 is installed inside the air inlet box 3. An air outlet 7 is provided at the bottom of the air inlet box 3. A dustproof net 5 is fixed to the top of the air inlet box 3 by bolts. The rain shield 2 is located above the air inlet box 3. A controller 8 is fixed to the inner top wall of the cabinet 1. A temperature sensor 9 is fixed to the inner left wall of the cabinet 1. The controller 8 is electrically connected to the cooling fan 6, and the temperature sensor 9 is electrically connected to the controller 8.
[0025] It should be noted that the temperature sensor 9 can be connected to the remote control system so that the temperature inside the cabinet 1 can be remotely accessed and monitored. When the temperature sensor 9 detects that the ambient temperature exceeds the set threshold, the controller 8 will start the cooling fan 6 for heat dissipation and cooling. When the temperature drops below the set threshold, the controller 8 will turn off the fan, thereby achieving energy-saving effects and preventing overheating of the cabinet.
[0026] Among them, the temperature sensor 9 can be a digital temperature sensor, such as a digital temperature sensor such as DS18B20, which usually has a built-in register and can be programmed to set the temperature threshold or set the working mode of the sensor. The digital temperature sensor is a temperature sensor that can directly output digital signals. Common digital temperature sensors include DS18B20, DHT11, DHT22, etc. These sensors are usually connected to a microcontroller or a single-chip microcomputer through a digital interface (such as I2C, SPI, OneWi re, etc.), and can directly read the temperature value without converting and processing the analog signal.
[0027] At the same time, the digital temperature sensor can be connected to a microcontroller or a single-chip microcomputer to control the fan through programming. A common practice is to connect the digital temperature sensor to the digital input pin of the microcontroller, and then write a program to read the temperature value of the sensor and control the fan on and off according to the set temperature threshold. When the temperature sensor detects that the ambient temperature exceeds the set threshold, the microcontroller can control the fan to turn on through the digital output pin; when the temperature drops below the set threshold, the microcontroller can turn off the fan.
[0028] In this embodiment, a plurality of heat dissipation holes 12 are provided on the left and right sides of the cabinet body 1, and U-shaped blocks 10 are fixed on the left and right sides of the cabinet body 1. A rain shield 11 is fixed inside the U-shaped block 10 by bolts. The rain shield 11 is tilted so that the heat dissipation holes 12 can be ventilated and dissipated while preventing rainwater from easily entering.
[0029] It should be noted that the heat dissipation holes 12 have a ventilation effect, and the rain shield 11 is tilted above the heat dissipation holes 12 to prevent rainwater from easily drifting into the heat dissipation holes on rainy days. The rain shield 11 is fixed in the U-shaped block 10 by bolts, so that the rain shield 11 can be removed or replaced.
[0030] The working principle of the above embodiment is as follows: when in use, pulling the pull rod 16 drives the limit rod 17 to move to one side of the I-shaped plate 15, which will cause the annular block 19 to squeeze the spring 18 to make it expand and contract, and then insert the column 4 into the fixed tube 13. After releasing the hand, the limit rod 17 can be inserted into the limit groove 14 through the rebound force of the spring 18, so that the column 4 can be limited, so that the rain shield 2 is installed on the top of the cabinet 1 and the air inlet box 3 is covered inside, and the rain shield 11 is conveniently blocked on the heat dissipation hole 12 to prevent rainwater from easily entering the cabinet 1 on rainy days, and the temperature sensor 9 is connected to the remote control system, which can monitor the temperature in the cabinet 1 in real time. When it is detected that the temperature in the cabinet 1 is too high, the cooling fan 6 can be controlled by the controller 8 to dissipate heat.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
