the slag guide groove 16 is plugged by arranging the stop block 17, sand is prevented from being poured into the cabinet body 2 through the slag guide groove 16, when the movable plate 7 moves downwards to the slag guide groove 16, the stop block 17 is pushed by the push block 19 to move downwards, the spring 18 is compressed, the slag guide groove 16 is in an open state, and impurities collected at the bottom of the inclined plate 14 can be led out outwards through the slag guide groove 16; when wind exists around the cabinet body 2, wind force acts on the surface of the monitoring plate 27, the monitoring rod 23 is pushed to deflect to one side through the monitoring plate 27, the movable ball 22 rotates in the spherical seat 21, the copper ball 24 at the bottom of the monitoring rod 23 is close to the copper ring 25, if the wind force reaches a certain degree, the copper ball 24 is in contact with the copper ring 25, a signal is transmitted to the controller, and the controller controls the electric telescopic rod 6 to extend and the radiating window 3 is plugged through the movable plate 7; by arranging the number of the monitoring plates 27 and the angles between the adjacent monitoring plates 27, the monitoring plates 27 can be driven to deflect no matter in which direction the wind blows, the response effect of the monitoring assembly 8 to the wind is improved, and by arranging the elastic membrane 28 to seal the spherical seat 21 and the movable ball 22, external sand can be prevented from entering a gap between the spherical seat 21 and the movable ball 22, the problem that the sand affects the rotation efficiency of the movable ball 22 is avoided, and the monitoring precision of the monitoring assembly 8 is ensured; when wind blows the monitoring plate 27 from one direction to deflect, the included angle between the wind direction and the monitoring plate 27 is changed from a right angle to an acute angle, at the moment, the wind acts on the lower side of the triangular plate 30, blows the triangular plate 30 to move in a direction far away from the supporting plate 29, stretches the elastic rope 31, and then when the wind stops, the elastic rope 31 pulls the triangular plate 30 to reset, if part of sand or dust is adhered to the surface of the monitoring plate 27, the triangular plate 30 can scrape the sand or dust on the surface of the monitoring plate 27 in the process, and the problem that the monitoring plate 27 is affected by the gravity of the attachment to cause poor wind response effect is prevented; by arranging the telescopic component, the guide rod 32 can be driven to move up and down in the guide cylinder 33 in the up and down movement process of the stop block 17, so that the guide limiting function is realized, the problem that the stop block 17 is askew and the blocking effect on the slag guide groove 16 is reduced due to the fact that the spring 18 is partially deformed is prevented; because the guide rod 32 is connected with the guide cylinder 33 through the screw-nut pair, the guide rod 32 can drive the guide cylinder 33 to rotate in the process of up-and-down movement in the guide cylinder 33, and then the guide cylinder 33 drives a plurality of metal wires 34 to rotate and clean in the spring 18, sand in the spring 18 is swept outwards, the problem that the spring 18 is difficult to compress due to excessive sand accumulation or the problem that deformation and damage occur when the spring 18 is compressed due to uneven sand distribution is avoided, and the service life of the device is prolonged.
