At the same time, the protective fan can automatically adjust its position through the switch rotation action of the door panel, making the inspection and maintenance operation of the power distribution device very convenient and quick.

[0026] 3.

When the roller is displaced to the tooth groove position of the tooth plate, the roller will drive the knocking block to change its position. With the continuous displacement of the roller, the roller bounces repeatedly on the uneven surface of the tooth plate, and the knocking block can be repeatedly displaced and knocked to the surface of the filter plate. At this time, the filter plate can be vibrated, so that the debris attached to the surface of the filter plate is vibrated off, which has a better cleaning effect on the filter plate.

[0032] Embodiment 2: Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, the outer surface of the sliding plate 504 close to the shell 101 is symmetrically fixedly connected with multiple groups of guide rods 508, and a pressure plate 510 is fixedly connected between the end surfaces of the two groups of guide rods 508.

[0035] In this embodiment, when in use, the two sliding plates 504 can be displaced synchronously through the connection between the linkage frame 401 and the two sliding plates 504. When moving, the linkage frame 401 will drive the first sliding block 402 to move along the first sliding rail 105, that is, the displacement of the linkage frame 401 is supported and limited by the coordinated setting of the first sliding rail 105 and the first sliding block 402, so that the displacement of the linkage frame 401 is relatively stable, ensuring the stable and synchronous displacement of the two sliding plates 504.

[0036] The effect and working principle achieved by the entire mechanism are as follows: when the explosion-proof and intrinsically safe combined power distribution device for mining is used, an electrical device 104 is installed inside the shell 101 to realize the equipment connection and power distribution function of the power distribution device. After the internal power distribution operation of the shell 101 is completed, the door panel 204 is rotated to cover the external opening of the shell 101, thereby protecting the inside of the shell 101. Through the use of filter plates 103 on both sides of the shell 101, heat will be generated inside the power distribution device during its operation, and the pores at the position of the filter plate 103 can play a role in ventilation and heat dissipation. With the use of the fan 606, the heat inside the shell 101 can be discharged to the outside of the filter plate 103 on one side. Since the power distribution device is equipped in the mine for use There is a lot of dust on the mine construction site. The filter plate 103 can prevent dust and debris from entering the shell 101 and causing internal circuit short circuit damage while playing the role of ventilation and heat dissipation. When the power distribution device is in use, the door panel 204 can be supported by the mounting seat 203 and rotated with the mounting shaft 202 as the axis. After the door panel 204 rotates toward the shell 101, the door panel 204 covers the shell 101 to provide shielding protection. In the process of covering the door panel 204, the rack 205 will be driven to move with it. At this time, the rack 205 will be displaced in a circular state with the mounting shaft 202 as the axis. When the rack 205 is displaced to the position of the reversing gear 109, it will drive it to rotate. The number of displacement meshing teeth of the rack 205 and the reversing gear 109 is The number of teeth of the reversing gear 109 is one-fourth of that of the toothed rack 205. Therefore, after the door panel 204 is closed and the rack 205 is displaced, the reversing gear 109 will be driven to complete a ninety-degree rotation. When the reversing gear 109 rotates, it will drive it to follow the reverse rotation of ninety degrees through the meshing with the first gear 108. The rotation of the first gear 108 and the reversing gear 109 is supported by the support shaft 106. When the first gear 108 rotates, it can drive the damping shaft 602 to follow the rotation of the same angle through the connection of the first synchronous wheel 107, the second belt 611 and the second synchronous wheel 610. When the damping shaft 602 rotates, it can drive the driven shaft 603 to follow the rotation of the same angle through the connection of the first pulley 607, the first belt 608 and the second pulley 609. The synchronous rotation of the shaft 602 and the driven shaft 603 can drive the mounting plate 605 to rotate outward. At this time, the multiple mounting plates 605 rotate from the state of being in contact with the inner wall of the housing 101 close to the electrical device 104 to the state of being flush with the filter plate 103. The mounting plates 605 on the left and right sides are arranged horizontally. At this time, through the operation of the fan 606, the multiple fans 606 blow air to one side synchronously. At this time, an air duct can be formed inside the housing 101, and air can be blown outward toward the filter plate 103 on one side, so that the heat generated by the operation of the power distribution device can be discharged. When it is necessary to open the door panel 204 to perform maintenance operations on the inside of the housing 101, the door panel 204 rotates outward, and the door panel 204 drives the rack 205 to mesh with the reversing gear 109 in the opposite direction.At this time, the reversing gear 109 can drive the damping shaft 602 and the driven shaft 603 to rotate ninety degrees in the opposite direction, and the opening range of the door panel 204 is limited by the cooperation of the extension rod 206 and the limit plate 207. After the door panel 204 is opened, it can drive multiple mounting plates 605 to move to a state flush with the electrical component 104. Multiple fans 606 are in operation at this time. The fan 606 can blow air to the outer opening position of the shell 101 with the mounting position of the electrical component 104 as the initial plane position. At this time, an airflow is generated inside the shell 101 from the direction of the electrical component 104 to the opening direction of the door panel 204. When the door panel 204 is opened to inspect and maintain the inside of the shell 101, the generation of outward airflow can effectively prevent dust and debris from passing through the opening. The fan 606 can enter the shell 101 through the opening position, and during the inspection and maintenance of the power distribution device, it plays a good protective role inside, meeting the requirements of explosion-proof and safe use of the power distribution device. At the same time, the protective fan 606 can automatically adjust its position through the switch rotation action of the door plate 204, making the inspection and maintenance operation of the power distribution device very convenient and quick. During the switch rotation of the door plate 204, the door plate 204 can realize synchronous control of the two cleaning components 5 through the connection with the driving component 3 and the linkage component 4, and realize the cleaning operation of the two filter plates 103 through the movement of the cleaning component 5. When the door plate 204 rotates, it can drive the first bevel gear 208 to follow the rotation through the connection with the mounting shaft 202. The first bevel gear 208 is driven by the first bevel gear 208 to rotate. The meshing with the second bevel gear 307 can drive the connecting shaft 305 to rotate accordingly, and the rotation of the connecting shaft 305 can drive the third gear 306 to rotate accordingly. When the third gear 306 rotates, it can drive the screw rod 302 to rotate accordingly through the meshing with the second gear 304. The rotation of the screw rod 302 can drive the sliding seat 303 to move accordingly. The sliding seat 303 can synchronously drive the sliding plate 504 on one side to move accordingly. The sliding plate 504 can drive the second slider 503 to move along the second slide rail 501. The matching setting of the second slider 503 and the second slide rail 501 limits the displacement of the sliding seat 303. At this time, the sliding plate 504 can move along the second slide rail 501. Since the first bevel gear 208 is moved toward the second bevel gear The transmission of the wheel 307 and the transmission of the third gear 306 to the second gear 304 both play a role in speeding up. Therefore, at this time, the rotation of the door panel 204 can drive the sliding plate 504 to completely cover the filter plate 103 to complete a one-way displacement. When the door panel 204 rotates in the opposite direction, the sliding plate 504 can be driven to continue to cover the filter plate 103 to complete the reset. When the driving component 3 drives the sliding plate 504 on one side to displace, the two sliding plates 504 are connected to the linkage frame 401, so that the two sliding plates 504 can be displaced synchronously. When the linkage frame 401 moves, it will drive the first slider 402 to move along the first slide rail 105, that is, the first slide rail 105 and the first slider 402 are matched to support and limit the displacement of the linkage frame 401.The displacement of the linkage frame 401 is relatively stable, ensuring the stable and synchronous displacement of the two sliding plates 504. When the sliding plate 504 moves through the surface of the filter plate 103, the sliding plate 504 can drive the brush roller 514 to move in contact with the surface of the filter plate 103 through the connection between the bracket 505 and the rotating shaft 506. The displacement of the brush roller 514 can brush off the dust attached to the surface of the filter plate 103, thereby cleaning the filter plate 103. When the bracket 505 moves, the brush roller 514 can extend to the bracket 505. The fourth gear 507 on the outside is in meshing state with the tooth plate 502, so the fourth gear 507 can drive the rotating shaft 506 to rotate during displacement, and the brush roller 514 will be in a rotating state while displacing. The rotating brush roller 514 can repeatedly rub against the surface of the filter plate 103, and has a better cleaning effect on the filter plate 103. At the same time, the knocking blocks 513 on both sides of the brush roller 514 will be in a fit state with the surface of the filter plate 103, and the rebound force of the spring 509 is utilized by using the roller 512. The roller 512 is in contact with the surface of the tooth plate 502, and the guide rod 508 is set to provide guide support for the displacement of the pressure plate 510. When the roller 512 moves to the tooth groove position of the tooth plate 502, the roller 512 will drive the knocking block 513 to change its position. As the roller 512 continues to move, the roller 512 bounces repeatedly on the uneven surface of the tooth plate 502, and the knocking block 513 can be repeatedly displaced and knocked to the surface of the filter plate 103, which can cause the filter plate 103 to vibrate. The debris attached to the surface of the filter plate 103 is vibrated off, which has a good cleaning effect on the filter plate 103. The cleaning of the filter plate 103 can be achieved by the coordinated use of the brush roller 514 and the knocking block 513 to achieve a more comprehensive cleaning, avoiding the blockage of the filter plate 103 and affecting the ventilation and heat dissipation performance of the housing 101. In addition, the displacement of the cleaning component 5 can be automatically driven by the change of the opening state of the door panel 204, without manual operation, which effectively improves the convenience of the inspection and maintenance operation of the power distribution device.
