walls

271, 272, 273, 274 also enclose an accommodating space for accommodating the cabinet door 202, and the width of the four sealing

walls

271, 272, 273, 274 (i.e., the distance extending in the direction away from the cabinet 201) is equal to or greater than the thickness of the cabinet door 202, so that in the state shown in fig. 1, the cabinet door 202 is completely accommodated in the cabinet 201 to prevent dust, rain water, and the like from entering the control cabinet 100.

As shown in fig. 2B, the cabinet door 202 has a substantially rectangular parallelepiped shape, and the cabinet door 202 is sized to close the rear opening 204 of the cavity 203 and to be accommodated in an accommodation space formed by four sealing

walls

271, 272, 273, 274. The periphery around cabinet door 202 is equipped with sealing strip 217, and sealing strip 217 can seal the clearance between cabinet door 202 and the cabinet body 201 to sealed appearance chamber 203. The double sealing of the sealing strip 217 and the four sealing

walls

271, 272, 273, 274 can greatly improve the sealing performance of the control cabinet 100.

The left side of cabinet door 202 is pivotally connected to a fourth connecting sidewall 264 by a pair of hinges 232. The right side of the cabinet door 202 is provided with a first stud hole 225, and a corresponding position on the second connecting sidewall 262 is provided with a first stud 226. When it is desired to close the rear opening 204 of the cavity 203, the door 202 is pivoted by the hinge 232, so that the right side of the door 202 is close to the second connecting sidewall 262 until the right side of the door 202 is tightly attached to the second connecting sidewall 262. At this time, the first stud 226 just passes through the corresponding first stud hole 225, and a nut (not shown) is fastened to the end of the first stud 226 passing through the first stud hole 225 from the outside of the cabinet door 202, so that the right side of the cabinet door 202 and the second connecting sidewall 262 are kept in a tightly connected state, thereby closing the cavity 203.

In the embodiment shown in the figures, the first and third connecting

side walls

261, 263 extend from the respective cabinet side walls by a distance set to: the height of the cabinet door 202 (i.e., the distance extending in the Z-axis direction in the figure) is substantially equal to (or slightly less than) the distance between the first and

third sealing walls

271, 273, such that the cabinet door 202 is just received between the first and

third sealing walls

271, 273. And the second and fourth connection sidewalls 262 and 264 are disposed in a different manner from the first and third connection sidewalls 261 and 263. Specifically, the second and fourth connecting

sidewalls

262, 264 extend from the respective cabinet sidewalls by a distance set to: when the cabinet door 202 is closed relative to the cabinet 201, the width of the cabinet door 202 (i.e., the distance extending along the XY plane in the figure) is less than the distance between the second and fourth sealing

walls

272 and 274, and the second and fourth connecting

sidewalls

262 and 264, respectively, extend beyond the cabinet door 202. With the above arrangement, the second connection sidewall 262 cannot be completely blocked by the cabinet door 202, so that the control cabinet 100 can be connected to the lampblack purification device 192 through the second connection sidewall 262. And the fourth connecting sidewall 264 cannot be completely blocked by the cabinet door 202, there is a distance between the left side (in fig. 2B) of the cabinet door 202 and the fourth sealing wall 274 on the fourth connecting sidewall 264, so that the cabinet door 202 can be opened without being blocked by the fourth sealing wall 274.

In the embodiment shown in the figures, the cabinet 201 is connected to the fume cleaning device 192 by: two sub-connectors 286 are provided on the outside of the fourth sealing wall 274 of the fourth connecting sidewall 264, with cylindrical protrusions (shown more clearly in FIG. 5) on the two sub-connectors 286 extending away from each other. The lampblack purification device 192 also has two sub-connecting members 287 (see fig. 2A) at corresponding positions, and has a concave portion that matches the cylindrical convex portion of the sub-connecting member 286. The sub-connection piece 286 and the sub-connection piece 287 are combined with each other by the convex and concave portions to form the connection piece 291. The cabinet 201 can be pivotally connected to the lampblack purification device 192 through a connection 291 to be opened or closed with respect to the lampblack purification device 192. The second connecting sidewall 262 is further provided with a second stud hole 288 at a portion extending beyond the cabinet door 202, and the end of the lampblack purification device 192 is provided with a second stud 289 corresponding to the second stud hole. When the cabinet 201 pivots toward the lampblack purification device 192 and the second sealing wall 272 abuts against the lampblack purification device 192, the second stud 289 on the lampblack purification device 192 penetrates through the second stud hole 288 on the second connection side wall 262 corresponding to the second stud hole 289, and a nut (not shown) is fastened to the end of the second stud 289 on the lampblack purification device 192, which penetrates through the second stud hole 288, so that the second connection side wall 262 of the cabinet 201 and the lampblack purification device 192 can be kept in a tightly connected state.

In the embodiment shown in the figures, referring to fig. 2B, the cabinet door 202 is pivotally connected to the cabinet 201 at its left side (first side) and detachably connected to the cabinet 201 at its right side (second side opposite to the first side). However, those skilled in the art will appreciate that in other embodiments, the two sides of the cabinet door 202 connected to the cabinet 201 need not be opposite sides, and the cabinet door 202 may be connected to the cabinet 201 at two adjacent sides. For example, the cabinet door 202 may be pivotally coupled to the cabinet 201 at a left side thereof and detachably coupled to the cabinet 201 at an upper or lower side thereof.

In the embodiment shown in the drawings, referring to fig. 1, the cabinet 201 is pivotally connected to the lampblack purification device 192 at a left side (first side) thereof, and detachably connected to the lampblack purification device 192 at a right side (second side opposite to the first side) thereof. However, it should be understood by those skilled in the art that in other embodiments, the two sides of the cabinet 201 connected to the lampblack purification device 192 do not need to be opposite, and the cabinet 201 may be connected to the lampblack purification device 192 at two adjacent sides. For example, the cabinet 201 may be pivotally coupled to the lampblack purification device 192 at a left side thereof, and detachably connected to the lampblack purification device 192 at an upper side or a lower side thereof.

In addition, in other embodiments, the manner of pivotal and separable connection between the cabinet door 202 and the cabinet 201, and the manner of pivotal and separable connection between the cabinet 201 and the lampblack purification device 192 may adopt a different manner from that shown in the embodiment in the drawings, and are not limited to the manner shown in the embodiment in the drawings.

With continued reference to fig. 2A and 2B, the control cabinet 100 also includes a high voltage insulator sub-module 281, a travel power switch module 282, and a power module 283. A high voltage insulator sub-module 281, a travel power switch module 282, and a power module 283 are housed within the receptacle 203. In this embodiment, the high voltage insulator sub-module 281 is pivotally connected to the cabinet side wall 242 of the cabinet 201, the stroke power switch module 282 is connected to the cabinet side wall 241, and the power module 283 is connected to the cabinet front wall 245. The power module 283 is used for supplying power to the high-voltage insulating submodule 281 and the stroke power switch module 282, the high-voltage insulating submodule 281 is used for generating a high-voltage electric field and a low-voltage electric field in the lampblack purification device 192, and the stroke power switch module 282 is used for switching on or off a control circuit on the lampblack purification device 192.

Fig. 3A is a partially enlarged view of a portion of the dashed line frame a in fig. 2B, for illustrating a specific structure of the high voltage insulating sub-module 281; fig. 3B is a perspective view of another perspective view of the high voltage insulator sub-module 281 shown in fig. 3A. As shown in fig. 3A and 3B, the high voltage insulator sub-module 281 comprises a high voltage insulator mount 320, a first high voltage insulator 321 and a second high voltage insulator 322. The high voltage insulator mounting bracket 320 is a rectangular thin plate having two circular openings through which the first and second

high voltage insulators

321 and 322 are mounted to the high voltage insulator mounting bracket 320. The high-voltage insulator mounting bracket 320 has one end pivotally connected to the cabinet side wall 242 by a high-voltage insulator support shaft 525 (see fig. 5), and the other end detachably connected to the cabinet front wall 245 by a receiving bracket 552 (see fig. 5) provided on the cabinet front wall 245 of the cabinet 201. The cabinet door 202 is further provided with holes 223 and 224 (see fig. 2B) matching the positions and sizes of the first high voltage insulator 321 and the second high voltage insulator 322, respectively. The ends of the first high-voltage insulator 321 and the second high-voltage insulator 322 far from the cabinet 201 can pass through the cabinet door 202 through the

holes

223 and 224 to contact the corresponding elements 293 and 294 (see fig. 2A) on the lampblack purification device 192, so as to generate a high-voltage electric field and a low-voltage electric field in the lampblack purification device 192. The structure of the high-voltage insulator supporting shaft 525 and the high-voltage insulator receiving bracket 552 will be described in detail with reference to fig. 5.

Fig. 4 is a partially enlarged view of a broken line frame B in fig. 2B, and is used to show a specific structure of the stroke power switch module 282. As shown in fig. 4, the stroke power switch module 282 includes a stroke power supply 411, a connector 413, and a power supply protection cover 414. The connector 413 includes a horizontal piece 465 and a vertical piece 466 connected to each other. The horizontal plate 465 is connected to the cabinet side wall 241 by welding or the like. The vertical piece 466 is provided with a rectangular opening 467, and the stroke power supply 411 is fixed to the vertical piece 466 through the opening 467. Specifically, the stroke power supply 411 has a substantially rectangular parallelepiped shape, and the outer peripheral dimension thereof is smaller than the dimension of the opening 467. The front end of the stroke power supply 411 is provided with a blocking piece 475, and the outer circumference size of the blocking piece 475 is larger than that of the opening 467. The stroke power source 411 further has a pair of resilient legs 477 at both sides thereof, one end of the resilient leg 477 being connected to the stroke power source 411 at a side thereof near the rear end 476, and the other end forming a free end, so that the distance between the pair of resilient legs 477 gradually increases in a direction from the rear end 476 to the front end of the stroke power source 411. The distance between the free ends of the pair of resilient legs 477, in their free state, is greater than the length of the opening 467. When installed, the stroke power supply 411 is placed in front of the opening 467, the rear end 476 of the stroke power supply 411 is aligned with the opening 467, and then the stroke power supply 411 is inserted rearwardly into the opening 467. During insertion, the two resilient legs 477 deform under the pressure of the opening 467. The stroke power supply 411 continues to be inserted leftward until the stopper piece 475 abuts against the vertical piece 466. At this time, the two resilient legs 477 just pass through the opening 467 completely, the two resilient legs 477 return to a natural state, and the right ends of the two resilient legs 477 abut against the vertical piece 466. The interaction of the two resilient legs 477 and the stop 475 secures the stroke power supply 411 to the connector 413.

The stroke power supply 411 is connected to the power module 283 so that the stroke power supply 411 is charged. In addition, the stroke power supply 411 has a switch button 478 projecting outward from the stopper 475. The switch button 478 is in an open position in a free state, and when the switch button 478 is pressed by an external force, the switch button 478 is in a closed position, so that the power supply module 283 supplies power to the high-voltage insulating sub-module 281. Specifically, when the second connecting sidewall 262 is connected to the end of the lampblack purification device 192, the switch button 478 contacts with a pin 212 (see fig. 2A) on the end of the lampblack purification device 192, and the pin 212 pushes the switch button 478 to the closed position, so that the lampblack purification device 192 is activated; when the second connecting sidewall 262 is separated from the lampblack purification device 192, the switch button 478 is separated from the thimble 212 of the lampblack purification device 192, and the switch button 478 automatically returns to the off position after the external force of the thimble 212 is lost, so that the lampblack purification device 192 stops working. Since the switch button 478 is in the closed position, the circuit inside the control cabinet 100 is completed, and the first high-voltage insulator 321 and the second high-voltage insulator 322 have high voltage electricity, which may endanger the personal safety of the operator. The present application thus provides a power protection cover 414 at the switch button 478 to prevent an operator from inadvertently pressing the switch button 478 during servicing.

Specifically, the power source protecting cover 414 is generally "Π" shaped and includes a window piece 468 disposed in front of the switch button 478, and a pair of legs 469 for spacing the window piece 468 from the stopper 475, the pair of legs 469 being coupled at both ends of the window piece 468. The ends of the two legs 469 distal from the louvers 468 also have connecting legs 470 extending perpendicularly outward. The connection leg 470 is connected to the vertical piece 466 of the connection member 413 by a screw or the like, so that the power protection cover 414 is fastened to the connection member 413. The window opening piece 468 includes a window 415, and the window 415 faces the switch button 478. The switch button 478 is located in the space between the window opener 468 and the stopper 475, and does not protrude from the window 415. The cabinet door 202 has an opening 216 (see fig. 2B) at a position corresponding to the window 415, and the thimble 212 at the end of the lampblack purification device 192 can pass through the opening 216 on the cabinet door 202 and the window 415 on the power supply protection cover 414 to contact the switch button 478 of the stroke power supply 411 and push the switch button 478 to the closed position to activate the lampblack purification device 192. The provision of the power source protection cover 414 prevents an operator from inadvertently pressing the switch button 478 of the power source 411 when the cabinet door 202 of the control cabinet 100 is opened, thereby avoiding potential electric shock hazard.

Fig. 5 is a perspective view of the cabinet 201 and some elements inside the cabinet shown in fig. 2B, for more clearly illustrating the power module 283 of the control cabinet 100 and the installation structure of the high voltage insulating sub-module 281, wherein the high voltage insulating sub-module 281 is removed. As shown in fig. 5, the power module 283 includes a power board 533 and a transformer 551. The power board 533 is connected to the front wall 245 of the cabinet and is connected to an external power source. The stroke power switch module 282 is connected to a power board 533, and the power board 533 can supply external power to the stroke power switch module 282.
