Two groups of insect-proof gauze 10 are installed on the inner walls on both sides of the power distribution cabinet body 1, and the insect-proof gauze 10 is located inside the ventilation slot 9 and on one side of the limit block 11. Four groups of heat dissipation slots 8 are evenly opened on the back wall of the power distribution cabinet body 1, and four groups of insect-proof nets 4 are evenly arranged on the back wall of the power distribution cabinet body 1, and the insect-proof nets 4 correspond to the positions of the heat dissipation slots 8. Four groups of fans 14 are evenly arranged on the front wall of the power distribution cabinet body 1, and the fans 14 correspond to the positions of the heat dissipation slots 8; The insect-proof net 4 is composed of a filter net 5 , a frame 6 and an electric grid 7 . The frame 6 is located outside the filter net 5 and the electric grid 7 , and the electric grid 7 is located on one side of the filter net 5 .

[0025] Furthermore, when the internal temperature is lower than a preset value range, the baffle 3 is in a closed state relative to the ventilation slot 9, and only the heat dissipation slot 8 can be ventilated, and an insect-proof net 4 is provided at the place where the heat dissipation slot 8 is connected to the outside world. The insect-proof net 4 is composed of a filter 5, a frame 6 and a power grid 7. The filter 5 is used to block flying mosquitoes with larger bodies. When mosquitoes with a body size smaller than the aperture of the filter 5 fly through the filter 5 and want to continue moving forward, the current on the power grid 7 will electrocute these mosquitoes, further preventing mosquitoes from entering the distribution cabinet body 1, so as to prevent mosquitoes from entering the distribution cabinet body 1 and causing damage to circuit components. When it is detected that the temperature of the temporal part of the distribution cabinet body 1 exceeds the preset value range, the controller 16 will send a control instruction to the fan 14 and the small control motor 12 through an electrical connection relationship, turn on the fan 14, increase the flow speed of the airflow, so as to speed up the transfer of internal heat to the outside world, start the small control motor 12, and drive the baffle 3 to rotate a certain angle in the ventilation slot 9. degree, in order to expand the connecting space between the ventilation slot 9 and the outside world, further improve the heat dissipation efficiency, and the insect-proof gauze 10 blocks mosquitoes to prevent mosquitoes from flying into the distribution cabinet body 1 from the ventilation slot 9 when the baffle 3 is opened.

[0026] See also Figure 3 and Figure 4An embodiment of the present invention is as follows: a power distribution cabinet with anti-impact protection function and a method of use, wherein a cabinet door 2 is installed on the front of the power distribution cabinet body 1, and a controller 16 and a mosquito killer 17 are installed on the back wall of the cabinet door 2, the mosquito killer 17 is located below the controller 16, and the mosquito killer 17 is electrically connected to the controller 16, and infrared sensors 15 are evenly arranged on the top wall of the heat dissipation slot 8, and the infrared sensor 15 is located between the insect-proof net 4 and the fan 14, and an odor sensor 24 is installed on the front wall of the power distribution cabinet body 1, and the odor sensor 24 is located between four groups of fans 14, and the odor sensor 24 is electrically connected to the controller 16, and a sound sensor 29 and a camera 30 are installed on the top wall of the power distribution cabinet body 1, and the sound sensor 29 is located on one side of the camera 30, and the sound sensor 29 and the camera 30 are both electrically connected to the controller 16.

[0027] Furthermore, the controller 16 is used to process various real-time data and determine whether the data exceeds a preset value range. When the internal temperature exceeds the preset value, the controller 16 will send a control instruction to the fan 14 and the small control motor 12 to achieve rapid cooling and heat dissipation. When the detected environmental parameters are abnormal, the controller 16 will send a signal to the remote control center through the wireless communication network of the peripheral device. During the heat dissipation process, the infrared sensor 15, the odor sensor 24, the sound sensor 29 and the camera 30 are used to detect whether there are mosquitoes entering under the blocking effect of the insect-proof net 4. The infrared sensor 15 is installed in the heat dissipation slot 8 and is located in front of the insect-proof net 4 to prevent the missed mosquitoes from passing through the insect-proof net 4. When the missed mosquitoes enter the monitoring area of ​​the infrared sensor 15, due to the difference in temperature between the mosquitoes and the environment, specific infrared radiation will be emitted. The pyroelectric infrared sensor inside the infrared sensor 15 can receive and sense these infrared radiation signals and sense the changes in the infrared radiation signals. To determine whether there are any escaped mosquitoes entering the distribution cabinet body 1 from the heat dissipation slot 8. Since the interior of the distribution cabinet body 1 is in a sealed state during the operation of the distribution box, the sound sensor 29 determines whether there are mosquitoes entering the distribution cabinet body 1 by capturing the sound generated by the mosquitoes when they are flying. The odor sensor 24 determines whether there are mosquitoes entering the distribution cabinet body 1 by monitoring the specific odors released by the mosquitoes. The camera 30 monitors the situation inside the distribution cabinet in real time, and combines image recognition technology to determine whether there are mosquitoes inside the distribution cabinet body 1. The interior of the distribution cabinet body 1 is fully monitored to determine whether there are mosquitoes. Once it is detected that there are escaped mosquitoes entering the distribution cabinet body 1, the controller 16 immediately controls the mosquito killer lamp 17 to turn on, uses ultraviolet light of a specific wavelength to attract mosquitoes, and then provides a high-voltage power grid to electrocute the mosquitoes to death, so as to eliminate the mosquitoes entering the distribution cabinet body 1, further eliminating the influence of mosquitoes on circuit components, and improving the safety and reliability of the equipment.

[0028] See also Figure 2 , Figure 3 and Figure 4 An embodiment of the present invention is: a power distribution cabinet with anti-impact protection function, wherein a shock absorbing assembly is installed inside the power distribution cabinet body 1, and the shock absorbing assembly is located between the sound sensor 29 and the fan 14. A mounting plate 22 is installed inside the shock absorbing assembly, and the mounting plate 22 is used to install electrical equipment. The shock absorbing assembly includes eight groups of shock absorbers 21 installed on the top wall and the bottom wall of the power distribution cabinet body 1, and a protective frame 20 is installed on the surfaces of the eight groups of shock absorbers 21 close to each other.

[0029] Furthermore, eight shock absorbers 21 are arranged inside the distribution cabinet body 1, and the eight shock absorbers 21 support the protective frame 20. A mounting plate 22 is arranged in the protective frame 20, and the mounting plate 22 is used to install various electrical components, such as busbar systems, measuring instruments, circuit breakers, etc. When the distribution cabinet body 1 is affected by external factors such as the external environment and accidental collisions, the shock absorbers 21 can effectively absorb and alleviate these impacts, and prevent the impacts from being transmitted to the electrical components on the mounting plate 22, thereby protecting the electrical components from damage, and extending the life of the electrical components in the distribution cabinet body 1 to a certain extent, thereby extending the life of the entire distribution cabinet.

[0030] See also Figure 4 and Figure 7 An embodiment of the present invention is: a power distribution cabinet with anti-impact protection function, the back wall of the power distribution cabinet body 1 is evenly arranged with four groups of rain covers 19, the rain covers 19 are located above the insect-proof net 4, and a conductive wireless water immersion sensor 13 is installed on the inner wall of one side of the power distribution cabinet body 1. The conductive wireless water immersion sensor 13 is used to detect whether there is water accumulation inside the power distribution cabinet body 1, and the conductive wireless water immersion sensor 13 is electrically connected to the controller 16.

[0031] Furthermore, the rain cover 19 is located above the insect-proof net 4 to block rainwater and prevent rainwater from entering the distribution cabinet body 1 through the insect-proof net 4, thereby damaging the electrical components in the distribution cabinet body 1. When the baffle 3 is opened, since the inclination direction of the baffle 3 can only be that the head of the baffle 3 is deflected toward the inner side of the distribution cabinet body 1, the baffle 3 itself has a blocking effect on rainwater, which improves the safety of the distribution cabinet to a certain extent, expands the adaptability of the equipment to the use environment, and ensures that the distribution cabinet can be used normally in a variety of environments. The conductive wireless water immersion sensor 13 is responsible for detecting whether there is rainwater in the distribution cabinet body 1 to prevent a small amount of rainwater from leaking into the distribution cabinet body 1. Once rainwater is detected in the distribution cabinet body 1, the controller 16 immediately sends a signal to the remote monitoring center. At the same time, the maintenance personnel promptly clean up the rainwater in the distribution cabinet body 1 to prevent damage to the internal electrical components caused by accumulation of rainwater.

[0032] See also Figure 1 and Figure 3 , an embodiment of the present invention: a power distribution cabinet with anti-impact protection function, a top cover 18 is installed on the top of the power distribution cabinet body 1, a temperature and humidity sensor 27 and a smoke sensor 28 are installed on the bottom of the top cover 18, and the smoke sensor 28 is located on one side of the temperature and humidity sensor 27, and the smoke sensor 28 and the temperature and humidity sensor 27 are both located behind the power distribution cabinet body 1; A temperature sensor 26 is installed on the top wall of the protection frame 20, and the temperature sensor 26 is located behind the mounting plate 22; The back wall of the mounting plate 22 is evenly provided with heat sinks 23 , and the back of the protection frame 20 is evenly provided with through holes 25 , which correspond to the positions of the heat sinks 23 .

[0033] Furthermore, when installing the power distribution cabinet body 1, the corresponding position and the number of the power distribution cabinet are pre-entered into the system of the remote monitoring center, so as to facilitate the subsequent rapid positioning of the abnormal power distribution cabinet position. The top cover 18 is inclined, and when it rains, rain water falls on the top cover 18 and will slide down naturally, avoiding the accumulation of rain water. The temperature and humidity sensor 27 and the smoke sensor 28 monitor the external environment of the power distribution cabinet body 1 in real time. When at least one of the three environmental parameters of temperature, humidity and smoke concentration is abnormal, the controller 16 will send an alarm signal to the remote monitoring center through the wireless communication network of the peripheral device, and send the number of the current power distribution cabinet to the remote monitoring center. , timely and maintenance personnel go to the site for inspection and maintenance, which helps to discover potential environmental risks in time and ensure the safe operation of electrical equipment. The temperature sensor 26 is used to monitor the temperature inside the power distribution cabinet body 1 in real time, and transmit the monitored temperature data to the controller 16 through an electrical connection relationship. The controller 16 processes the data to determine whether the temperature in the power distribution cabinet body 1 exceeds the preset value range. Once the temperature exceeds the preset value range, the controller 16 will send a control instruction to the fan 14 and the small control motor 12 to increase the heat dissipation rate, so as to prevent the electrical components inside the power distribution cabinet body 1 from being in a high temperature state for a long time, affecting the service life of the electrical components; Since the mounting plate 22 is covered with holes, the heat generated by the electrical components can be effectively transferred to the rear of the mounting plate 22, and the heat sink 23 effectively absorbs the heat of the electrical components. With the assistance of the fan 14, the airflow generated by the fan 14 is used to dissipate the heat absorbed by the heat sink 23 to the outside of the distribution cabinet body 1, thereby achieving rapid heat dissipation.

[0034] Furthermore, the method for using the power distribution cabinet with anti-impact protection function comprises the following steps: Step S1: first use the temperature sensor 26 to detect the temperature inside the power distribution cabinet body 1 to determine whether the internal temperature exceeds a preset value range; Step S2: when it is detected that the internal temperature exceeds a threshold, the baffle 3 is opened and the fan 14 is started for rapid ventilation and heat dissipation; Step S3, while performing ventilation and heat dissipation, the power grid 7 is powered on to prevent mosquitoes from entering the power distribution cabinet body 1 through the heat dissipation slots 8; Step S4, then turn on the infrared sensor 15, the odor sensor 24, the sound sensor 29 and the camera 30 to detect whether there are mosquitoes entering the power distribution cabinet body 1 through the insect-proof net 4; In step S4, the following steps are also included: Step S41: When it is detected that there are mosquitoes inside the power distribution cabinet body 1, the controller 16 controls the mosquito killing lamp 17 to start killing mosquitoes.

[0035] Working principle: When the internal temperature is lower than the preset value range, the baffle 3 is in a closed state relative to the ventilation slot 9, and only the heat dissipation slot 8 can be ventilated, and an insect-proof net 4 is provided at the place where the heat dissipation slot 8 is connected to the outside world. The insect-proof net 4 is composed of a filter 5, a frame 6 and a power grid 7. The filter 5 is used to block flying mosquitoes with larger bodies. When mosquitoes with a body size smaller than the aperture of the filter 5 fly through the filter 5 and want to continue moving forward, the current on the power grid 7 will electrocute these mosquitoes, further preventing mosquitoes from entering the main body 1 of the power distribution cabinet, so as to prevent mosquitoes from entering the main body 1 of the power distribution cabinet and causing damage to circuit components; When it is detected that the temperature of the top of the distribution cabinet body 1 exceeds the preset value range, the controller 16 will send a control instruction to the fan 14 and the small control motor 12 through an electrical connection relationship, turn on the fan 14, increase the flow speed of the airflow to speed up the transfer of internal heat to the outside, start the small control motor 12, and drive the baffle 3 to rotate a certain angle in the ventilation slot 9 to expand the connection space between the ventilation slot 9 and the outside, further improve the heat dissipation efficiency, and the insect-proof mesh 10 blocks mosquitoes to prevent mosquitoes from flying into the distribution cabinet body 1 from the ventilation slot 9 when the baffle 3 is opened. When the internal temperature of the distribution cabinet body 1 returns to normal, the baffle 3 is rotated in the opposite direction until the baffle 3 is blocked by the limit block 11, the operation of the small control motor 12 is stopped, and the fan 14 is turned off.
