8. The power distribution box with a sand prevention function according to claim 1, wherein: the distribution box body opposite side is connected fixedly and is provided with the blast pipe, blast pipe inner wall connection fixedly is provided with the otter board.
9. The power distribution box with a sand prevention function according to claim 8, wherein: the sealing mechanism comprises an electric push rod, a connecting rod and a sealing plate, wherein the electric push rod is fixedly connected with the inner wall of the distribution box body, the connecting rod is fixedly arranged at the output end of the electric push rod, the sealing plate is fixedly arranged at the two ends of the connecting rod respectively, and the two sealing plates are respectively arranged in sliding fit with one end of the air inlet pipe and one end of the air outlet pipe.
10. The application method of the distribution box with the sand prevention function is characterized by comprising the following steps of:
s1, when the temperature inside the distribution box body is too high and heat dissipation is required, starting an electric push rod, so that the electric push rod drives a connecting rod to move, and two connecting sealing plates can be moved away;
s2, the starting motor drives the driving wheel to rotate, and the driving wheel drives the fan blades connected with the driven wheel to rotate, so that external air can be sucked into the distribution box body through the air inlet pipe and then discharged from the exhaust pipe at the other side of the distribution box body to dissipate heat;
s3, when the fan blades rotate, the connected poking rod is driven to rotate, the poking rod drives the contact rod to move, then the sliding seat can be moved in a reciprocating mode by matching with the tension spring, sand and dust in air are filtered through the two arc-shaped filter screens respectively, and the air entering the power distribution box body is kept clean;
s4, when the sliding seat reciprocates, the swing plate connected with the gear swings reciprocally under the action of the rack, so that the brush plate can continuously clean the arc-shaped filter screen, and the filtering effect of the arc-shaped filter screen is maintained;
s5, when the filtered air passes through the air inlet pipe, a part of the filtered air enters the motor base through the air guide pipe, so that the heat dissipation effect on the motor can be realized.
