They work together and are widely used in substations, distribution rooms, and other places, playing a key role in ensuring the stable operation and reliable power supply of power systems. Patent application publication number CN115912093A discloses a waterproof and dustproof power distribution cabinet, which relates to the technical field of power distribution cabinets and includes a low-voltage cabinet, a high-voltage cabinet installed above the low-voltage cabinet, a card holder installed above the interior of the low-voltage cabinet, a first busbar plug-in strip installed below the card holder, an isolation plate installed below the second busbar plug-in strip, and a second wire conduit passing through the interior of the isolation plate, an air switch installed below the isolation plate, and a first terminal block installed below the air switch, a fuse installed below the first terminal block, a first main busbar joint installed on one side of the interior of the high-voltage cabinet, and a second main busbar joint installed on the side of the branch busbar joint away from the first main busbar joint; The above patent can discharge the water vapor inside the distribution cabinet, but during the use of the distribution switch, dust and water vapor will enter the inside of the distribution switch, affecting the use of the distribution switch. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a power distribution switch with waterproof and dustproof effects to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a power distribution switch with waterproof and dustproof effects, comprising a power distribution switch, the bottom of which is fixedly connected to a box component, the outer wall of which is fixedly connected to a bracket, and the outer wall of which is fixedly connected to a negative pressure mechanism; The negative pressure mechanism comprises: The empty bin is fixedly connected to the outer wall of the box component. When the power distribution switch and the box component are in use, the fan is powered on and starts to blow air through the airflow pipe. The airflow blows out from top to bottom. When the airflow passes through the empty bin, it guides the airflow in the empty bin. Airflow holes are provided between the empty bin and the box component. Therefore, when the airflow flows through the empty bin, combined with Bernoulli's principle, the faster the airflow speed, the lower the pressure. Then, under pressure, the water vapor and dust in the box component and the power distribution switch are guided into the empty bin. The outer wall of the box component also has airflow holes, which will allow air to enter. Airflow holes are provided between the empty bin and the box body. The negative pressure mechanism utilizes the airflow from the fan. Based on the Bernoulli principle, the water vapor and dust in the box body and the distribution switch are guided to the empty bin under pressure. The water vapor and dust then enter the storage box and are effectively filtered and intercepted by the filter plate. This greatly improves the dust and water vapor treatment effect, provides a good environment for the normal operation of the distribution switch, and effectively extends its service life. A fan, wherein the outer wall of the fan is fixedly connected to the outer wall of the bracket; An auxiliary component is fixedly connected to the outer wall of the box component.

[0005] Preferably, the box component is communicated with the interior of the bracket.

[0006] Preferably, the outer wall of the fan is fixedly connected with an airflow pipe, and the airflow pipe is arranged at the top position of the empty warehouse. When the power distribution switch and the box body components are in operation, their own temperature increases, and the airflow difference guides the increased temperature to be blown from the exhaust port to the bottom of the box body components. Most of the water vapor and dust settle to the bottom, so the increase in their own temperature is used in conjunction with the flow of air to clean the water vapor that settles to the bottom, thereby avoiding the accumulation of water vapor and causing corrosion to the device.

[0007] Preferably, the auxiliary component includes a storage box, which is fixedly connected to the outer wall of the box body component away from the bottom position of the empty warehouse. The outer wall of the storage box is rotatably connected to the door panel. The airflow will enter the storage box after passing through the empty warehouse. The filter plate filters the airflow so that dust and water vapor are filtered by the filter plate, and the shape of the filter plate is set to intercept water vapor and dust at a position close to the door panel. The temperature of the box body component and the distribution switch will increase during operation, and then the airflow difference will guide the increased temperature to be blown from the exhaust port to the inner bottom position of the box body component, and most of the water vapor and dust will sink to the bottom.

[0008] Preferably, a filter plate is fixedly connected to the inner wall of the storage box, and a discharge port is provided between the outer wall of the box component and the storage box.

[0011] Preferably, the two ends of the airflow bin are rotatably connected to the top of the distribution switch through bearings. The setting of the cleaning mechanism further optimizes the dust prevention effect. The fan blades drive the transmission rod to rotate, causing the toggle block to hit the connecting plate, driving the airflow bin to rotate, and then changing the airflow blowing direction of the second zigzag tube. This dynamic airflow adjustment method can clean more positions of the distribution switch more comprehensively, reduce the impact of dust and water vapor on the distribution switch, and ensure normal use by staff.

[0012] Preferably, the outer wall of the fan is rotatably connected to a transmission rod, and the outer wall of the transmission rod is fixedly connected to a toggle block. When the airflow tube blows out air, part of the airflow will pass through the first zigzag tube and the airflow bin and be blown out from the second zigzag tube. The airflow bin is connected to the top position of the power distribution switch through a bearing. The fan itself drives the airflow by the rotation of the internal fan blades, so when the fan blades drive the transmission rod to rotate, the toggle block will be driven to rotate. The connecting plate approaches the toggle block under its own gravity, and then the toggle block hits the connecting plate to drive the airflow bin to rotate. The second zigzag tube and the first zigzag tube are made of elastic material, so the rotation of the airflow bin will drive the second zigzag tube to swing, thereby changing the blowing direction of the airflow. The outer wall of the airflow bin is fixedly connected to the connecting plate, and the connecting plate is in active contact with the toggle block.
