Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] A mine-used intelligent high-voltage switch cabinet, as Figures 1-10As shown in the figure, it includes an outer cabinet body 1. An inner cabinet body 2 is fixedly connected inside the outer cabinet body 1. A cabinet door 38 is rotatably installed on the inner cabinet body 2. Two sets of closed frames 3 are fixedly connected between the outer cabinet body 1 and the inner cabinet body 2. A cavity 39 is formed between the two sets of closed frames 3. A heat dissipation port 5 is opened on the side wall of the inner cabinet body 2. The heat dissipation port 5 communicates with the cavity 39. A rectangular opening 4 is opened on the outer cabinet body 1 corresponding to the position of the heat dissipation port 5. A dust-proof net ring 9 is sleeved outside the inner cabinet body 2. The dust-proof net ring 9 is located between the rectangular opening 4 and the heat dissipation port 5.

[0034] Vertical shafts 6 are rotatably installed at the four corners of the outer wall of the inner cabinet body 2. The vertical shafts 6 are located inside the dust-proof net ring 9. A servo motor 7 for driving one of the vertical shafts 6 to rotate is fixedly connected to the outer wall of the inner cabinet body 2. Tooth rings 8 are fixedly connected to both ends of the side wall of the vertical shaft 6. Tooth grooves 10 are opened at both ends of the inner wall of the dust-proof net ring 9. The tooth rings 8 are meshed and driven with the tooth grooves 10. A cleaning port 13 is opened on the back of the outer cabinet body 1. An ash removal component for rolling and cleaning the dust-proof net ring 9 is slidably installed in the cleaning port 13.

[0035] By dividing the cabinet body of the switch cabinet into the outer cabinet body 1 and the inner cabinet body 2, installation openings for installing the cabinet door 38 are opened at the front ends of the inner cabinet body 2 and the outer cabinet body 1. Communication openings through which the dust-proof net ring 9 passes are preset on both sides of the installation opening. The dust-proof net ring 9 passes through the two sets of communication openings, so that the dust-proof net ring 9 maintains a rectangular ring shape and rolls. At this time, the cabinet door 38 is located inside the dust-proof net ring 9. The closed frame 3 independently seals a cavity 39 between the outer cabinet body 1 and the inner cabinet body 2. The cavity 39 is located between the heat dissipation port 5 and the rectangular opening 4. The dust-proof net ring 9 is located in the cavity 39, isolating the area between the rectangular opening 4 and the heat dissipation port 5, so that the air is filtered by the dust-proof net ring 9.

[0036] A dust-proof net ring 9 and multiple sets of vertical shafts 6 are installed between the outer cabinet body 1 and the inner cabinet body 2. The servo motor 7 (model 110ST-M05030) drives one of the vertical shafts 6 to rotate, so that the multiple sets of vertical shafts 6 and the dust-proof net ring 9 are meshed and driven through the tooth rings 8 and the tooth grooves 10, driving the dust-proof net ring 9 to roll in a rectangular ring form, so that the dust-proof net ring 9 between the rectangular opening 4 and the heat dissipation port 5 rolls and rotates. When the air passes through the rectangular opening 4 and the heat dissipation port 5, the dust is filtered by the dust-proof net ring 9. The position of the dust-proof net ring 9 corresponding to the rectangular opening 4 is covered with dust. The external controller controls the intermittent movement of the servo motor 7, thereby controlling the intermittent rolling of the dust-proof net ring 9. The rolling dust-proof net ring 9 moves the area covered with dust in the rectangular opening 4 into the cleaning port 13 to be cleaned. The area of the dust-proof net ring 9 that is not covered with dust enters the rectangular opening 4 to work. The heat dissipation port 5 is always covered with the dust-proof net ring 9. The ash removal component automatically cleans the dust-proof net ring 9. There is no need to extract or disassemble the dust-proof net ring 9. Automatic ash removal does not require manual labor and is more suitable for use in mines.

[0037] As Figures 1-6As shown, the cleaning port 13 communicates with the cavity 39. The upper and lower ends of the cleaning port 13 are flush with the two groups of closed frames 3 respectively. The dust-proof net ring 9 passes through the cleaning port 13. The cabinet door 38 is located inside the dust-proof net ring 9. The width of the dust-proof net ring 9 is greater than the width of the rectangular opening 4 and greater than the width of the heat dissipation opening 5.

[0038] The outer cabinet 1 is provided with a cleaning port 13, so that the dust-proof net ring 9 on the back of this mine-used intelligent high-voltage switch cabinet is exposed. The dust removal component cleans the dust-proof net ring 9 in the cleaning port 13, and the removed ash falls outside the switch cabinet through the cleaning port 13. Since the upper and lower ends of the cleaning port 13 are flush with the two groups of closed frames 3 respectively, there will be no space for accumulating dust between the lower closed frame 3 and the cleaning port 13. The lower end of the cleaning port 13 and the position of the lower end of the sealing frame corresponding to the cleaning port 13 are set as inclined planes, which is more convenient for dust discharge.

[0039] The dust-proof net ring 9 can completely cover the rectangular opening 4 and the heat dissipation opening 5, so that the air flow inside and outside the switch cabinet must pass through the dust-proof net ring 9.

[0040] As Figure 2 、 Figures 7-10 As shown, the dust removal component includes a mounting frame 18. The mounting frame 18 is slidably mounted on the outer wall of the inner cabinet 2 and is located inside the cleaning port 13. A mounting plate 23 is fixedly connected to the side wall of the mounting frame 18. A first shaft 21 and a second shaft 25 are rotatably mounted on the mounting plate 23. Brush layers 22 are fixedly connected to the outer walls of the first shaft 21 and the second shaft 25. The two brush layers 22 respectively roll-brush the two sides of the dust-proof net ring 9. A connecting frame 20 is fixedly connected to the lower end of the mounting frame 18. The lower ends of the first shaft 21 and the second shaft 25 are rotatably mounted with the connecting frame 20.

[0041] The mounting frame 18 reciprocally slides at the position inside the cleaning port 13 on the outer wall of the inner cabinet 2, and the sliding direction is the left-right direction. Therefore, the dust removal component can roll-brush the dust removal net ring in the cleaning port 13 back and forth, and the cleaning area is large.

[0042] The connecting frame 20 supports and connects the lower ends of the first shaft 21 and the second shaft 25.

[0043] The first shaft 21 and the second shaft 25 with brush layers 22 covering their surfaces are used to roll-brush the two sides of the dust removal net ring to remove the dust covering the dust removal net ring. At the same time, the dust removal component reciprocally slides inside the cleaning port 13, so that the brush layer 22 can clean a large area of the dust-proof net ring 9 located inside the cleaning port 13. The cleaned dust-proof net ring 9 waits to be rotated to the side of the heat dissipation opening 5. The cleaning efficiency is high and it will not affect the rotation of the dust-proof net ring 9. It is mechanically cleaned, saving time and effort.

[0044] As Figures 7-8As shown, both ends of the second shaft body 25 are slidably mated with the mounting plate 23 and the connecting frame 20 respectively. One ends of the first shaft body 21 and the second shaft body 25 above the mounting plate 23 are fixedly connected with a first helical gear 24 and a second helical gear 26 respectively. One end of the mounting plate 23 away from the mounting frame 18 is fixedly connected with a first motor 27. The output end of the first motor 27 is fixedly connected with a rotating shaft 28. The side wall of the rotating shaft 28 is provided with a fixed gear 29 and a moving gear 30. The fixed gear 29 is meshed and driven with the first helical gear 24, and the moving gear 30 is meshed and driven with the second helical gear 26.

[0045] The two ends of the second shaft body 25 are slidably mated with the mounting plate 23 and the connecting frame 20 respectively, which means that the second shaft body 25 can rotate and slide on the mounting plate 23 and the connecting frame 20. As Figure 8 shown, the connecting hole of the second shaft body 25 is set to be oval, so that the second shaft body 25 can rotate and slide in the oval hole, so that the distance between the first shaft body 21 and the second shaft body 25 can be adjusted, which is convenient for the replacement of the dust-proof net ring 9.

[0046] The first motor 27 (model F260) drives the rotating shaft 28 to rotate, so that the fixed gear 29 and the moving gear 30 rotate. The fixed gear 29 and the moving gear 30 are respectively meshed and driven with the first helical gear 24 and the second helical gear 26, so that the first shaft body 21 and the second shaft body 25 rotate.

[0047] As Figures 7-8 shown, the fixed gear 29 is fixedly connected with the rotating shaft 28. The moving gear 30 is slidably mounted on the rotating shaft 28. The fixed gear 29, the moving gear 30 and the rotating shaft 28 are coaxial. A moving frame 32 is slidably mounted on one side of the mounting plate 23. Both ends of the moving frame 32 are located at the upper end and the lower end of the mounting plate 23 respectively. The position of the side wall of the second shaft body 25 below the mounting plate 23 is rotatably connected with the lower end of the moving frame 32. One side of the moving gear 30 is rotatably connected with the upper end of the moving frame 32. The rotating shaft 28 penetrates through the upper end of the moving frame 32. A telescopic electric cylinder 31 is fixedly connected to the side wall of the mounting frame 18. The output end of the telescopic electric cylinder 31 is fixedly connected with the middle part of the moving frame 32.

[0048] The moving gear 30 is driven to rotate as the rotating shaft 28 rotates, and the moving gear 30 can slide on the rotating shaft 28. The output end of the telescopic electric cylinder 31 (model TA-01-30) pushes and pulls the moving frame 32, so that the moving frame 32 drives the second shaft body 25 and the moving gear 30 to move at the same time, which not only does not prevent the rotating shaft 28 from driving the second helical gear 26 to rotate through the moving gear 30, but also can adjust the distance between the first shaft body 21 and the second shaft body 25.

[0049] When the dust-proof net ring 9 is replaced, the distance between the first shaft body 21 and the second shaft body 25 becomes larger, which is convenient for the replacement of the dust-proof net ring 9. After replacement, the distance becomes smaller to brush the dust-proof net ring 9.

[0050] As Figure 2 、Figure 9 , Figure 10 As shown in Figure 10 , two sets of slide rails 33 are provided at the position of the outer wall of the inner cabinet 2 within the cleaning port 13. The back of the mounting frame 18 and the back of the connecting frame 20 are respectively slidably connected to the two sets of slide rails 33. Two sets of toothed rollers 14 are rotatably installed at the position of the outer wall of the inner cabinet 2 within the cleaning port 13. A toothed belt 15 is commonly engaged and driven outside the two sets of toothed rollers 14. A driving assembly 16 for driving the rotation of the toothed rollers 14 is fixedly connected to the outer wall of the inner cabinet 2. A driving frame 17 is fixedly connected to the lower layer of the toothed belt 15. A driving block 19 is fixedly connected to the upper end of the mounting frame 18. The driving frame 17 is inserted into the driving block 19 for driving the driving block 19 to drive the mounting frame 18 to slide.

[0051] The mounting frame 18 and the connecting frame 20 will not disengage from the slide rails 33, enabling the dust removal assembly to slide smoothly back and forth. The driving assembly 16 includes structures such as a motor (a motor with a rotatable output end that can rotate forward and backward), gears, etc., for driving the rotation of the toothed rollers 14. The toothed belt 15 and the dust-proof net ring 9 are both in a properly taut state. The toothed rollers 14 drive the toothed belt 15 to run. The driving frame 17 moves within the cleaning port 13, driving the mounting frame 18 to move through the driving block 19, thereby driving the dust removal assembly to move back and forth.

[0052] As Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown in Figure 6 , a plurality of connecting rods 35 are inserted and installed at the position of the outer cabinet 1 corresponding to the rectangular opening 4. One end of the plurality of connecting rods 35 is commonly fixedly connected to an outer pressing frame 34. The other end of the plurality of connecting rods 35 is commonly fixedly connected to an inner pressing frame 37. The inner pressing frame 37 is located within the cavity 39 and is used for pressing the dust-proof net ring 9. Tightening springs 36 are sleeved on the side walls of the plurality of connecting rods 35. The tightening springs 36 are in a stretched state. One end of the tightening spring 36 is fixedly connected to the outer wall of the outer cabinet 1, and the other end is fixedly connected to the outer pressing frame 34.

[0053] The tightening spring 36 pulls the outer pressing frame 34, causing the inner pressing frame 37 to press the dust-proof net ring 9, pressing the dust-proof net ring 9 tightly against the heat dissipation port 5. At the same time, the inner pressing frame 37 slides in a sealed manner between the walls of the rectangular opening 4. Therefore, the air flow between the rectangular opening 4, the dust-proof net ring 9, and the heat dissipation port 5 must pass through the dust-proof net ring 9. The inner pressing frame 37 pressing the dust-proof net ring 9 will not affect the rotation and rolling of the dust-proof net ring 9.

[0054] As Figures 3-4 As shown in Figures 3-4 , the dust-proof net ring 9 is provided with a connection port. Clamping ports 11 are provided on both sides of the dust-proof net ring 9 at the position of the connection port. A locking plate 12 is clamped and installed between every two corresponding clamping ports 11.

[0055] The dust-proof net ring 9 is unfolded into a rectangle. After the two ends are butted, the locking plate 12 is used for clamping, so that the dust-proof net ring 9 is in a ring shape, enabling the dust-proof net ring 9 to be pulled out of the switch cabinet for replacement and facilitating the opening of the cabinet door 38.

[0056] The working principle of a mine-used intelligent high-voltage switch cabinet provided by the present invention is as follows:

[0057] The cabinet body of the switch cabinet is divided into an outer cabinet body 1 and an inner cabinet body 2. A dust-proof net ring 9 and multiple groups of vertical shafts 6 are installed between the outer cabinet body 1 and the inner cabinet body 2. The servo motor 7 drives the vertical shafts 6 to rotate, driving the dust-proof net ring 9 to roll, so that the dust-proof net ring 9 between the rectangular opening 4 and the heat dissipation opening 5 rolls and rotates alternately. When air passes through the rectangular opening 4 and the heat dissipation opening 5, the dust is filtered by the dust-proof net ring 9. The rolling dust-proof net ring 9 moves the area covered with dust in the rectangular opening 4 into the cleaning opening 13 to be cleaned, and the area of the dust-proof net ring 9 not covered with dust enters the rectangular opening 4 to work. The dust removal assembly automatically cleans the dust-proof net ring 9 located in the cleaning opening 13, without the need to pull out or disassemble the dust-proof net ring 9, realizing automatic dust removal without manual operation, and being more suitable for use in mines.

[0058] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
