[0030] The discharging assembly 33 comprises two spring rods 333 slidably connected with the inner walls of the dustproof frame 112, the side walls of the two spring rods 333 are rotatably connected with the inner walls of the connecting rod two 332, and the inner walls of the flow guide frame 211 are rotatably connected with two arc-shaped dust separation plates 335; The bottom of the wind direction plate 221 is fixedly connected with a push rod 334, the bottoms of the two spring plates two 336 are fixedly connected with three spring plates two 336, and the six spring plates two 336 are arranged in three groups, and the side walls of the two arc-shaped dust separation plates 335 are fixedly connected with the side walls of the two groups of spring plates two 336; The dust removal plate 326 contacts the spring rod 333, pushes the spring rod 333 to move, and accumulates the elastic force of the spring rod 333 under compression. When the spring rod 333 moves, it drives the connecting rod two 332 to rotate, so that the connecting rod two 332 pulls the inclined frame 331 to rise and separate from the flow guide frame 211, cancels the blockage of the sand and dust, and the sand and dust at the bottom of the flow guide frame 211 flows out through the bottom of the inclined frame 331, effectively preventing the sand and dust from accumulating too much at the bottom of the flow guide frame 211, thereby affecting the subsequent sedimentation of the sand and dust.
[0031] The number of the above components is not limited, and those skilled in the art can freely set according to actual needs, as long as the components are installed at the corresponding component connection positions.
[0032] The use method of the high-protection power distribution cabinet comprises the following steps: S1: air flow introduction: external air flow is sucked into the guide frame 211 by starting the fan 113, the air flow contacts the arc-shaped guide plate 212, and the air flow flows along the arc-shaped surface of the arc-shaped guide plate 212, so that the air flow is divided; S2: air flow collision: the air flow flows between the arc-shaped guide plate 212 and the guide frame 211, until the air flow enters the arc-shaped block 213 and is again divided by the arc-shaped block 213, so that the sand in the air flow is divided into two arc-shaped blocks 213, until the air flow and the sand flow out of the two arc-shaped blocks 213, so that the sand in the two air flows collides with each other, reducing the kinetic energy of the sand.
[0033] One specific application of the embodiment is: when the application is used, external air flow is sucked into the guide frame 211 by starting the fan 113, the air flow contacts the arc-shaped guide plate 212, and the air flow flows along the arc-shaped surface of the arc-shaped guide plate 212, so that the air flow is divided, at this time, the air flow flows between the arc-shaped guide plate 212 and the guide frame 211, until the air flow enters the arc-shaped block 213 and is again divided by the arc-shaped block 213, so that the sand in the air flow is divided into two arc-shaped blocks 213, until the air flow and the sand flow out of the two arc-shaped blocks 213, so that the sand in the two air flows collides with each other, reducing the kinetic energy of the sand. At the same time, the air flow flowing from the arc-shaped block 213 moves to the relatively empty area in the guide frame 211, allowing the air flow to diffuse, reducing the flow rate of the gas, allowing the larger sand in the gas to settle at the bottom of the guide frame 211, and then the air flow moves upward along the side of the arc-shaped guide plate 212 away from the arc-shaped block 213, contacts the filter screen 122, filters the remaining fine sand in the air flow through the filter screen 122, and the filtered air flow enters the distribution cabinet 111 to cool the distribution cabinet 111. The air flow entering the distribution cabinet 111 is discharged through the exhaust plate 114, the sand in the air flow is collided, the kinetic energy of the sand is slowed down, the air flow is diffused, the flow rate of the air flow is reduced, the larger sand in the air flow is settled, the sand contacting the filter screen 122 is reduced, the burden of the filter screen 122 is reduced, and the cleaning and replacement of the filter screen 122 are reduced. Secondly, to address the issue of strong winds carrying significant amounts of sand and dust entering the distribution cabinet 111 through the exhaust panel 114 during windy weather, the strong winds will cause the wind vane 221 to rotate. The wind vane 221 will then drive the push plate 224 to rotate, compressing the spring plate 222 and accumulating rebound force. As the push plate 224 continues to rotate, it will contact the start switch 223. At this point, the electric telescopic rod 312 will start operating for a period of time. During this time, the electric telescopic rod 312 extends to push the pneumatic frame 311 towards the filter screen 122. As the pneumatic frame 311 moves, the extrusion frame 313, via connecting rod 314, pushes the connecting frame 315 to move until the connecting frame 315 is blocked by the dust-blocking frame 112. At this point, the connecting frame 315 stops moving, and the pneumatic frame 311 continues to move, causing the connecting rod 314 to rotate, pushing the extrusion frame 313 downwards. When the extrusion frame 313 descends past the air hole, as shown below: Figure 8 As shown in state G, the compression frame 313 will compress the gas inside the pressure frame 311. At this time, the compressed gas will be blocked by the air baffle plate 321 and the diverter plate 322, thus increasing the gas pressure. As the pressure frame 311 continues to move, it will move to the top of the filter screen 122. Simultaneously, the bottom of the compression frame 313 will contact the air baffle plate 321, pushing the air baffle plate 321 down and separating it from the pressure frame 311, thus removing the obstruction to the gas. At the same time, the spring... The reset rod 323 accumulates rebound force. At this time, the high-pressure gas in the air pressure frame 311 will be sprayed out towards the filter screen 122, flushing out the sand and dust in the filter screen 122, keeping the filter screen 122 unobstructed, effectively preventing the filter screen 122 from absorbing too much sand and dust, causing the filter screen 122 to become clogged, affecting the airflow, and causing the gas flow discharged from the exhaust plate 114 to weaken, reducing the blocking force against external sand and dust. In windy weather, external sand and dust will enter the distribution cabinet 111 from the exhaust plate 114. When the filter screen 122 is cleaned, the electric telescopic rod 312 will retract, causing the pneumatic frame 311 to move away from the filter screen 122. The extrusion frame 313 will pull the connecting frame 315 to move via the connecting rod 314. At this time, the spring return rod 323 will release its rebound force, pushing the extrusion frame 313 to rise. As the connecting frame 315 continues to move, it will be blocked and stop moving. The pneumatic frame 311 will continue to move, and the extrusion frame 313 will rise due to the pull of the connecting rod 314 until the extrusion frame 313 returns to its original position. The air hole will then connect with the interior of the pneumatic frame 311 to replenish the gas. Secondly, when the air pressure frame 311 moves, the U-shaped rod 324 drives the collection frame 325 and the dust discharge plate 326 to move synchronously. When the air pressure frame 311 moves to the top of the filter screen 122, the collection frame 325 moves to the bottom of the filter screen 122. The collection frame 325 blocks the airflow from contacting the filter screen 122, and the sand and dust cleaned from the filter screen 122 fall into the collection frame 325. It then moves through the inclined surface of the collection frame 325 to the dust discharge plate 326 and is discharged to the bottom of the guide frame 211. At the same time, during the movement of the dust discharge plate 326, it contacts the spring rod 333, pushing the spring rod 333 to move, causing it to be compressed and accumulating rebound force. When the spring rod 333 moves... This will drive the second connecting rod 332 to rotate, causing the connecting rod 332 to pull the inclined frame 331 upward and separate it from the guide frame 211, thus removing the obstruction of sand and dust. The sand and dust at the bottom of the guide frame 211 will then flow out through the bottom of the inclined frame 331. When the sand and dust falling from the filter screen 122 is collected by the collection frame 325, it will block the airflow from contacting the filter screen 122, effectively preventing the high-pressure gas ejected from the air pressure frame 311 from contacting the airflow at the bottom of the filter screen 122, which would cause them to collide and weaken the impact force of the gas in the air pressure frame 311, thus affecting the cleaning effect on the filter screen 122. In addition, by discharging the sand and dust at the bottom of the guide frame 211, it is effectively prevented that too much sand and dust will accumulate at the bottom of the guide frame 211, affecting the subsequent settling of sand and dust. Secondly, to address the issue of excessively fast airflow within the guide frame 211 due to enhanced suction of the fan 113 during strong winds, the rotation of the wind vane 221 also drives the push rod 334 to rotate. During this rotation, the push rod 334 contacts the arc-shaped dust-collecting plate 335, causing it to rotate and compress the spring plate 336. This allows the spring plate 336 to accumulate rebound force. The reduced distance between the arc-shaped dust-collecting plate 335 and the guide frame 211 after rotation obstructs the airflow entering the guide frame 211, slowing down the airflow speed and reducing the impact of sand and dust. This effectively prevents the arc-shaped block 213 from insufficiently mitigating the impact of sand and dust due to high airflow speed and strong impact, which could potentially damage the filter screen 122.
