The device comprises a high-voltage solid-state soft start box, a side protection assembly and a front protection assembly. Electromagnets are arranged at the two ends of the high-voltage solid-state soft start box, and a one-way exhaust valve is arranged in the high-voltage solid-state soft start box. After the through slot is staggered with the one-way exhaust valve, the first piston block will move up along with the reset spring rod due to the loss of suction force. After the ash inlet is connected with the one-way air inlet valve, the dust collected in the ash collecting seat will enter the air control cavity through the ash discharge groove, the ash inlet and the one-way air inlet valve due to the suction force generated when the second piston block moves up synchronously with the first piston block.

[0036] In summary, the high pressure solid soft start device with intelligent protection shell, when using, first, the adapter seat 602 passes through the through slot on both sides inside the high pressure solid soft start box 1, can realize the butt joint with high pressure solid soft start box 1 through the fixation with buffer spring rod 7, high pressure solid soft start box 1 in the process of use, through the work of suction fan 605, the adsorption force can be transmitted from air suction groove 607 to the inside of high pressure solid soft start box 1, which makes the high temperature generated in the working process of high pressure solid soft start box 1 and the dust entering the inside of high pressure solid soft start box 1 can be sucked into the inside of adapter seat 602 through air suction groove 607, the inside of dust collecting seat 606 is paved with dust collecting net, which can make air pass through and leave dust, which makes the hot air sucked out of the inside of high pressure solid soft start box 1 in the process of suction of suction fan 605, can be discharged from the equipment through exhaust groove 604, and the sucked dust is attached to the inside of dust collecting seat 606;

[0037] Then the high-voltage solid-state soft start box 1 in the process of work, if the high-voltage solid-state soft start box 1 two wings are impacted by foreign matter, the foreign matter will contact with the side wing plate 601, the side wing plate 601 is extruded, and the adapter seat 602 is driven to slide in the high-voltage solid-state soft start box 1, which makes the butt joint plate 603 can stretch the buffer spring rod 7 to produce deformation, by making the buffer spring rod 7 produce deformation, the impact on the high-voltage solid-state soft start box 1 can be effectively absorbed, so as to avoid the impact of foreign matter on the normal work of the high-voltage solid-state soft start box 1, through the above design, by integrating the heat dissipation component in the protective shell, the function of the equipment can be highly integrated, at the same time, the design can effectively distinguish the working parts and auxiliary parts in the high-voltage solid-state soft start box 1, so as to facilitate the subsequent maintenance and cleaning, in addition, the butt joint plate 603 can be separated from the adapter seat 602 by removing the bolts, so that the side protection assembly 6 and the high-voltage solid-state soft start box 1 can be quickly separated, when the side wing plate 601 is damaged due to impact, or the internal air suction component is damaged, or the internal air duct needs to be cleaned, the side protection assembly 6 and the high-voltage solid-state soft start box 1 can be quickly disassembled and replaced or repaired;

[0038] Then the side wing plate 601 is in the normal position, the through slot 610 will be communicated with the one-way exhaust valve 3, in the process of air suction of the air suction fan 605, the suction force will enter the air control cavity 501 through the through slot 610 and the one-way exhaust valve 3, which makes the air at the bottom end of the first piston block 504 gradually exhaust, after the air at the bottom end of the first piston block 504 is exhausted, the first piston block 504 will stretch the reset spring rod 503 under the action of the pressure difference between the two ends and displace in the air control cavity 501, the first piston block 504 drives the second piston block 506 to displace synchronously through the linkage rod 505, which makes the first piston block 504 and the second piston block 506 can move synchronously to the bottom end of the air control cavity 501 with the air pressure difference;

[0039] Subsequently, when the side wing plate 601 is displaced by impact, the adapter seat 602 will be displaced, which will misalign the through slot 610 with the one-way exhaust valve 3 and make the ash inlet 609 communicate with the one-way air inlet valve 4. After the through slot 610 is misaligned with the one-way exhaust valve 3, the first piston block 504 will be pulled upward by the return spring rod 503 due to the loss of suction force. After the ash inlet 609 communicates with the one-way air inlet valve 4, the dust collected in the ash collecting seat 606 will be sucked into the air control cavity 501 through the ash outlet 608, the ash inlet 609 and the one-way air inlet valve 4 due to the suction force generated when the second piston block 506 moves upward synchronously with the first piston block 504. Through the above design, the device can automatically clean the collected dust when it is impacted. After the side wing plate 601 is reset, the first piston block 504 drives the second piston block 506 to move downward again, and the second piston block 506 can push the dust collected in the air control cavity 501 out of the device through the one-way ash outlet 508. In addition, the electromagnet 2 can attract the side wing plate 601 through work. Through the above design, even if the side wing plate 601 is not impacted, the device can still displace it to clean the dust. The function of the electromagnet 2 attracting the side wing plate 601 can also be used to determine whether the side wing plate 601 can normally displace under stress during the maintenance of the device.

[0040] Then the staff pulls the rotating protective plate 801, which can rotate through the rotating shaft, so that the rotating protective plate 801 can cover the front end of the high-voltage solid-state soft start box 1, and the fitting plate 802 can be fitted with the high-voltage solid-state soft start box 1. After the fitting plate 802 is fitted with the high-voltage solid-state soft start box 1, the staff pulls the extension telescopic connecting rod 804, which can extend into the connecting slot 803. The extension telescopic connecting rod 804 can be connected with the connecting slot 803, which can lock the rotation of the rotating protective plate 801. The rotating protective plate 801 can be stably covered on the front end of the high-voltage solid-state soft start box 1 through the support of the fitting plate 802 and the high-voltage solid-state soft start box 1, which can effectively protect the front end of the high-voltage solid-state soft start box 1.

[0041] Finally, the rotation of the protective plate 801 is locked during the protection process of the high-voltage solid-state soft start box 1, and the rotation of the rotation protective plate 801 is locked. This can effectively prevent the cabinet door of the high-voltage solid-state soft start box 1 from being accidentally opened. In addition, when the side wing plate 601 is extruded and displaced, it can drive the rotation of the rotation protective plate 801 to be displaced synchronously. The telescopic butt joint rod 804 can penetrate into the butt joint groove 803 to avoid interference caused by the displacement of the rotation protective plate 801. During the displacement of the rotation protective plate 801, the fitting plate 802 can be displaced on the surface of the high-voltage solid-state soft start box 1. If there is a size error between the high-voltage solid-state soft start box 1 and the fitting plate 802, or other reasons cause the cabinet door of the high-voltage solid-state soft start box 1 to have a gap, the displacement of the fitting plate 802 to the high-voltage solid-state soft start box 1 can effectively push the opened cabinet door to be closed. Through the design, the working stability and safety of the high-voltage solid-state soft start box 1 can be further improved.
