Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: An assembly structure of an exhaust gas treatment electric control cabinet, comprising a bottom plate 1, a top plate 2, a back plate 3, a door plate 4, two side plates 5 and three rectangular frames 6, wherein the back plate 3 and the two side plates 5 are respectively arranged on the three rectangular frames 6, as shown in FIG. Figure 1 and Figure 2 and Figure 3 , further comprising an assembly mechanism, wherein the three rectangular frames 6 are connected together by the assembly mechanism, and the back panel 3, the two side panels 5 and the three rectangular frames 6 form a U-shaped cabinet wall, and the door panel 4 is hinged at one end of one of the side panels 5 away from the back panel 3; A first connecting mechanism, wherein the bottom plate 1 is detachably connected to the three rectangular frames 6 through the first connecting mechanism, and the bottom plate 1 is located below the three rectangular frames 6; A second connecting mechanism, the top plate 2 is detachably connected to the three rectangular frames 6 through the second connecting mechanism, and the top plate 2 is located above the three rectangular frames 6; The heat dissipation mechanism is arranged on the two side panels 5.

[0022] like Figure 1 and Figure 2 and Figure 3 During assembly, the three rectangular frames 6 are connected together through the assembly mechanism, and then the three rectangular frames 6 are installed on the bottom plate 1 through the first connecting mechanism. Then, the top plate 2 is installed on the top of the three rectangular frames 6 through the second connecting mechanism. At this time, the bottom plate 1, top plate 2, back plate 3, door plate 4, two side plates 5 and three rectangular frames 6 can be assembled into an electric control cabinet. The disassembly and assembly are simple, and the electric control cabinet is easy to transport after being disassembled.

[0023] like Figure 3 The assembly mechanism includes slide grooves 7 arranged on opposite sides of the outer wall of one of the rectangular frames 6, and the two slide grooves 7 are arranged along the length direction of the rectangular frame 6 and are connected to the top of the rectangular frame 6. Slide plates 8 are vertically slidably connected in the two slide grooves 7, and the two slide plates 8 are fixedly connected to the remaining two rectangular frames 6. The back plate 3 is arranged on the rectangular frame 6 with the slide grooves 7, and the side plate 5 is arranged on the rectangular frame 6 fixedly connected to the slide plates 8. When the three rectangular frames 6 need to be connected together, it is only necessary to match the slide plates 8 on the two rectangular frames 6 with the slide grooves 8 with the slide grooves 7 on the rectangular frame 6 with the slide grooves 7, and slide the slide plates 8 vertically into the slide grooves 7. At this time, the three rectangular frames 6 can be connected together, and disassembly and assembly are simple.

[0024] like Figure 1 and Figure 2 and Figure 4 and Figure 5 The first connecting mechanism includes a fixing plate 9 provided on the bottom plate 1, the bottom ends of the three rectangular frames 6 are in contact with the top end of the bottom plate 1, and the bottom ends of the three rectangular frames 6 are provided with two plug-in posts 10, and one end of the bottom plate 1 close to the plug-in posts 10 is provided with a slot 12 for vertical insertion of the plug-in posts 10. The fixing plate 9 is located in the U-shaped cabinet wall formed by the back plate 3, the two side plates 5 and the three rectangular frames 6. The three rectangular frames 6 are in contact with the fixing plate 9 on one side thereof, and the fixing plate 9 is provided with a slot 12 for limiting the fixing plate 9 on one end thereof close to the three rectangular frames 6. The rectangular frame 6 is provided with a limiting member for vertically upward movement. The limiting member includes a placement groove 13 provided on the fixed plate 9 near one end of the rectangular frame 6, and a limiting plate 14 is horizontally slidably connected in the placement groove 13. The side of the limiting plate 14 facing away from the bottom of the placement groove 13 extends outside the placement groove 13 and extends into the rectangular frame 6. The bottom end of the limiting plate 14 contacts the bottom end inside the rectangular frame 6. The side of the limiting plate 14 away from the bottom of the placement groove 13 is an inclined surface 15, and the inclined surface 15 is arranged upward. A compression spring 16 is provided between the placement groove 13 and the limiting plate 14. The structure of the second connecting mechanism is consistent with that of the first connecting mechanism. At this time, the fixing plate 9 is arranged at the bottom end of the top plate 2, the plug post 10 is arranged at the top end of the rectangular frame 6, the top end of the limiting plate 14 in the second connecting mechanism contacts the top end inside the rectangular frame 6, and the inclined surface 15 of the limiting plate 14 in the second connecting mechanism is arranged downward.

[0025] like Figure 1 and Figure 2 and Figure 4 and Figure 5When the three rectangular frames 6 need to be installed on the base plate 1, it is only necessary to match the pins 10 at the bottom of the three rectangular frames 6 with the slots 12 on the base plate 1 one by one and insert them from top to bottom. During the insertion process after the pins 10 correspond to the slots 12, the rectangular frame 6 will squeeze the limiting plate 14 into the placement groove 13 through the inclined surface 15 on the limiting plate 14. At this time, the compression spring 16 is compressed. When the pins 10 on the rectangular frame 6 are fully inserted into the slots 12, the bottom end of the limiting plate 14 will be flush with the bottom end of the rectangular frame 6. The compressed compression spring 16 will push the limiting plate 14 away from the bottom of the placement groove 13 until the limiting plate 14 enters the rectangular frame 6 on the side away from the placement groove 13. At this time, the bottom end of the limiting plate 14 will contact the bottom end of the rectangular frame 6. At this time, the limiting plate 14 can restrict the rectangular frame 6 from moving up and down. The cooperation between the plug post 10 and the slot 12 can restrict the rectangular frame 6 from moving forward, backward, left, and right. Through the above process, the three rectangular frames 6 can be installed on the base plate 1. After the three rectangular frames 6 are mounted on the bottom plate 1, the top plate 2 is placed above the three rectangular frames 6, and the slots 12 on the top plate 2 correspond to the pins 10 at the top of the three rectangular frames 6 one by one, and the top plate 2 is pressed so that the pins 10 are inserted into the slots 12 on the top plate 2. During this process, the rectangular frame 6 will squeeze the limiting plate 14 into the placement groove 13 of the top plate 2 through the inclined surface 15 on the limiting plate 14 in the second connecting mechanism. At this time, the compression spring 16 in the second connecting mechanism is compressed. When the pins 10 at the top of the rectangular frame 6 are fully inserted into the pins 10 on the top plate 2, the top plate 2 will be pressed. When in the slot 12, the top of the limiting plate 14 in the second connecting mechanism will be flush with the top of the rectangular frame 6. At this time, the compressed compression spring 16 will push the limiting plate 14 away from the bottom of the placement slot 13 until the limiting plate 14 enters the rectangular frame 6 away from the side of the placement slot 13. At this time, the top of the limiting plate 14 in the second connecting mechanism will contact the top of the rectangular frame 6. At this time, the top plate 2 can be installed on the top of the three rectangular frames 6 through the cooperation of the limiting plate 14 in the second connecting mechanism, the plug column 10 and the slot 12. The installation is simple and the disassembly is convenient.

[0026] like Figure 1 and Figure 2The heat dissipation mechanism includes a plurality of long strip first heat dissipation holes 17 provided at the lower side of one side panel 5, and each first heat dissipation hole 17 is spaced apart along the width direction of the side panel 5. A plurality of long strip second heat dissipation holes 18 are provided at the upper side of the other side panel 5. The side panel 5 provided with the first heat dissipation holes 17 is provided with a sealing member for sealing each first heat dissipation hole 17. The purpose of this arrangement is to facilitate heat dissipation of the electric control cabinet assembled by the bottom panel 1, the top panel 2, the back panel 3, the door panel 4, the two side panels 5 and the three rectangular frames 6 through each second heat dissipation hole 18. By releasing the sealing member from each first heat dissipation hole 17, the heat dissipation effect of the electric control cabinet can be improved through each first heat dissipation hole 17. Since the first heat dissipation holes 17 are arranged below one side of the side plate 5, each first heat dissipation hole 17 is closed by a sealing member, which can reduce the occurrence of external reptiles entering the electric control cabinet through the first heat dissipation holes 17, and is simple and convenient to use.

[0027] like Figure 1 and Figure 2 and Figure 6 and Figure 7 and Figure 8 The closure member includes a U-shaped mounting platform 19 and a mounting plate 20 detachably connected to the mounting platform 19. The mounting platform 19 is arranged on the side panel 5 provided with the first heat dissipation holes 17, and the mounting platform 19 is connected to each first heat dissipation hole 17. The side of the mounting plate 20 close to the side panel 5 is in contact with the side panel 5, and the side of the mounting plate 20 away from the side panel 5 is provided with a plurality of connecting grooves 21, and each connecting groove 21 is connected to each first heat dissipation hole 17 in a one-to-one correspondence. A rotating shaft 22 is rotatably connected between the top and bottom ends of each connecting groove 21, and two opposite closing plates 23 are provided on each rotating shaft 22, and the upper and lower ends of the closing plate 23 are connected to each other. The ends are in contact with the groove wall of the connecting groove 21. The two closing plates 23 on each rotating shaft 22 are arc-shaped surfaces on the side away from the rotating shaft 22 and are in contact with the groove wall of the connecting groove 21. The top of the mounting plate 20 is provided with a mounting groove 25. The top of each rotating shaft 22 is coaxially provided with a drive shaft 26. The top of each drive shaft 26 extends vertically into the mounting groove 25. Each drive shaft 26 is connected by a chain transmission mechanism 27. A motor 28 is provided on the groove wall of the mounting groove 25. The motor 28 drives each drive shaft 26 to rotate through the chain transmission mechanism 27. A cover plate 29 for closing the notch of the mounting groove 25 is detachably connected to the mounting plate 20.

[0028] like Figure 1 and Figure 2 and Figure 6 and Figure 7 and Figure 8The connecting groove 21 can be closed by the rotating shaft 22 in the first heat dissipation hole 17 and the two closing plates 23 on the rotating shaft 22, so that the first heat dissipation hole 17 can be closed, reducing the situation where external crawlers enter the electric control cabinet through the connecting groove 21 and the first heat dissipation hole 17 in turn. When it is necessary to improve the heat dissipation effect of the electric control cabinet through the first heat dissipation hole 17, it is only necessary to turn on the motor 28. The rotating shaft of the motor 28 drives each drive shaft 26 to rotate through the chain transmission mechanism 27, and each drive shaft 26 drives each rotating shaft 22 to rotate. At this time, the rotating shaft 22 will drive the closing plate 23 to rotate in the first heat dissipation hole 17 along the rotating axis of the rotating shaft 22. At this time, the first heat dissipation hole 17 and the connecting groove 21 are connected. The through groove 21 can dissipate heat for the electric control cabinet, and the closing plate 23 that rotates along the rotation axis of the rotating shaft 22 can improve the circulation effect of air in the connecting groove 21, thereby improving the heat dissipation effect of the electric control cabinet, and when the closing plate 23 rotates along the rotation axis of the rotating shaft 22, the rotating closing plate 23 can reduce the occurrence of external reptiles entering the first heat dissipation hole 17 from the connecting groove 21. Through the above process, the situation where external reptiles enter the first heat dissipation hole 17 from the connecting groove 21 can be reduced, and the circulation effect of air in the connecting groove 21 can be improved, thereby improving the heat dissipation effect of the electric control cabinet. It is simple and convenient to use. The chain transmission mechanism 27 is an existing structure, and this application will not describe it in detail here.

[0029] like Figure 1 and Figure 2 The inner sides of the two vertical sides of the mounting platform 19 are vertically provided with sliding grooves 30, and the two sliding grooves 30 are vertically slidably connected with sliding plates 31. The sides of the two sliding plates 31 close to each other are fixedly connected to the mounting plate 20. The two sliding grooves 30 are communicated with the top of the mounting platform 19, and the bottom end of the mounting plate 20 contacts the bottom end of the mounting platform 19. The purpose of this setting is that the mounting plate 20 can be installed on the mounting platform 19 through the cooperation of the sliding grooves 30 and the sliding plates 31. The disassembly and assembly are simple, which makes it convenient to remove the mounting plate 20 later to maintain the motor 28 on the mounting plate 20, and remove the mounting plate 20 to facilitate the transportation of the side panel.

[0030] like Figure 2 and Figure 9 and Figure 10, the mounting platform 19 is arranged on the side of the side panel 5 away from the rectangular frame 6, and the two side panels 5 are horizontally provided with a slide bar 32 on the side close to each other, and the two rectangular frames 6 with side panels 5 are provided with a slideway 33 for the slide bar 32 to slide horizontally in, and the side panel 5 is connected to the rectangular frame 6 by the slide bar 32 and the slideway 33 to slide horizontally in the direction close to or away from the back panel 3. The rectangular frame 6 with the side panel 5 is provided with a limiting member for limiting the sliding of the side panel 5 on the rectangular frame 6, and the limiting member includes a limiting block 34 arranged at one end of the side panel 5 away from the back panel 3, and a limiting groove 35 for the limiting block 34 to slide horizontally in is provided on the rectangular frame 6 with the side panel 5. The limiting groove 35 is communicated with the side of the rectangular frame 6 away from the back panel 3, and the limiting groove 3 The latch 36 is connected to the inner wall of the cabinet for vertical sliding movement. The latch 36 is located above the limit block 34, and a post 37 is vertically provided at the bottom end of the latch 36. The top end of the limit block 34 is provided with a slot 38 for vertically inserting the post 37. The purpose of this arrangement is that when it is necessary to inspect the equipment in the electric control cabinet, it is only necessary to open the door panel 4 to inspect the equipment in the electric control cabinet. The door panel 4 can also be opened and the latch 36 is pushed upward to separate the post 37 on the latch 36 from the slot 38 on the limit block 34. Then, the side panel 5 is pulled away from the back panel 3. The side panel 5 drives the slide bar 32 to slide in the slideway 33. At this time, the side panel 5 can be opened to inspect the equipment in the electric control cabinet from both sides. It is simple and convenient to use.
