Description

Technical Field

[0001] The present application relates to the technical field of electric control application cabinets, and in particular to an electric control application cabinet. Background Art

[0002] The electric control application cabinet, also known as the electric control cabinet, is a control cabinet (box) that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. It integrates various electrical components and control equipment, etc., and can realize real-time monitoring, adjustment and protection of the equipment's operating status.

[0003] The electrical components and control devices in the electric control application cabinet will generate heat when working, so a heat dissipation device needs to be installed on the electric control application cabinet to dissipate heat. At present, the heat dissipation device is usually to install an air fan in the electric control application cabinet, and to open air holes adjacent to the air fan on the cabinet wall. When in use, the air fan drives the outside air into the electric control application cabinet to dissipate heat for the electrical components and control devices in the electric control application cabinet.

[0004] However, when the outside is in a humid environment, there is more water vapor in the air entering the electric control application cabinet. When the amount of water vapor is large, it may affect the normal use of electrical components and control equipment in the electric control application cabinet. Summary of the invention

[0007] By adopting the above technical solution, the electric control application cabinet realizes heat dissipation and dehumidification inside the electric control application cabinet through the air inlet, heat dissipation port, air inlet pipe, air inlet fan, transmission assembly, water absorbent cotton, extrusion strip, control assembly and water collection box. The air inlet fan inhales external air, drives the extrusion strip to move up and down through the transmission assembly to drive the connecting column, squeezes the water absorbent cotton, effectively squeezes out the moisture in the water absorbent cotton, maintains the water absorption capacity of the water absorbent cotton, reduces the amount of water vapor entering the electric control application cabinet during heat dissipation, and reduces the possibility of damage to electrical components inside the electric control application cabinet due to excessive humidity. At the same time, the air is discharged through the heat dissipation port to achieve a heat dissipation effect, ensuring the stable operation of the components inside the electric control application cabinet.

[0008] Optionally, the transmission assembly includes a rotating shaft, a rotating bevel gear, a transmission bevel gear, a transmission belt and a first reciprocating screw rod; The first reciprocating screw is rotatably connected to the air inlet pipe, and the connecting column is threadedly connected to the first reciprocating screw; The rotating shaft is rotatably connected to the air inlet pipe, the transmission bevel gear is arranged on the outer peripheral side of the rotating shaft, the rotating bevel gear is arranged on the outer peripheral side of the rotating shaft, and the rotating bevel gear is meshed with the transmission bevel gear; The transmission belt is connected end to end and is sleeved on the rotating shaft and the outer peripheral side of the first reciprocating screw rod.

The driving spring is arranged in the connecting column and corresponds to the control block one by one. The driving spring drives the control block to protrude out of the connecting column. The top of the control block is inclined to form a control surface facing the absorbent cotton. When the extrusion bar moves away from the absorbent cotton, the extrusion bar slides on the control surface to push the control block to slide into the connecting column. The pushing block is arranged on the inner tube wall at the bottom of the air inlet tube and corresponds to the extrusion strip one by one, and the bottom of the extrusion strip is inclined to form an extrusion surface facing the water-absorbing cotton; When the extrusion strip is close to the bottom wall of the air inlet pipe, the pushing block slides on the extrusion surface to push the extrusion strip to the side of the control block away from the absorbent cotton; The control column slides up and down on the limiting block and the top protrudes out of the limiting block. The control rope is slidably arranged in the limiting block and the connecting column. One end of the control rope is connected to the bottom of the control block, and the other end is connected to the outer wall of the control column. When the extrusion strip is close to the top wall of the air inlet pipe, the control column slides toward the inside of the connecting column, and at this time, the control rope pulls the control block to slide into the connecting column.

[0011] By adopting the above technical solution, the control component realizes intelligent control of the movement of the squeezing strip through the ingenious design of the control spring, control block, driving spring, push block, control column and control rope. When the squeezing strip is close to the top wall of the air inlet pipe, the control column slides and pulls the control block to make the squeezing strips close to each other to squeeze the absorbent cotton; when the squeezing strip is close to the bottom wall of the air inlet pipe, the push block pushes the squeezing strip away from the absorbent cotton. This design not only ensures the dehumidification effect of the absorbent cotton, but also reduces the possibility of damage to the absorbent cotton caused by excessive squeezing.

[0012] Optionally, a curved surface structure is formed on the top of the pushing block.

[0017] By adopting the above technical solution, the automatic cleaning of the dust filter is realized through the design of the mounting block, the second reciprocating screw, the linkage belt, the cleaning roller and the cleaning brush. When the mounting block moves downward, it drives the cleaning roller into the water storage box, so that the water flow in the water storage box flushes the dust on the cleaning brush and makes it enter a wet state, reducing the possibility of dust floating when the cleaning brush cleans the dust filter.

[0018] Optionally, a power gear is provided on the outer peripheral side of the cleaning roller, and a power rack extending in the vertical direction is provided on the inner wall of the air inlet pipe, and the power gear is meshed with the power rack.

[0027] The following is combined with Figure 1-10 This application is described in further detail.

[0028] An embodiment of the present application discloses an electric control application cabinet.

[0029] See also Figure 1 and Figure 2 The electric control application cabinet includes a cabinet body 1, and a mounting cavity 11 is provided in the cabinet body 1, and electrical components and control equipment are installed in the mounting cavity 11. An air inlet 12 is provided on the vertical side wall of the cabinet body 1, and the air inlet 12 is located near the bottom of the cabinet body 1. The air inlet 12 is connected to the mounting cavity 11, and is used to allow external air to enter the mounting cavity 11 to dissipate heat for the electrical components and control equipment. A heat dissipation port 13 is provided on the side wall of the cabinet body 1, and the heat dissipation port 13 is located above the air inlet 12. The air entering the mounting cavity 11 takes away the heat emitted by the electrical components and control equipment and is discharged from the heat dissipation port 13.

[0030] See also Figure 2 and Figure 3, an air inlet pipe 2 is fixedly connected to the cabinet body 1, and the air inlet pipe 2 extends in the horizontal direction, and one side of the pipe opening is aligned with and connected to the air inlet 12. The electric control application cabinet also includes an inlet fan 3 and a water-absorbing cotton 22. The inlet fan 3 is fixedly installed at a side of the pipe opening of the air inlet pipe 2 away from the air inlet 12. When the inlet fan 3 is started, it drives the outside air to form an airflow from the air inlet 12 into the air inlet pipe 2, and then blows the airflow into the installation cavity 11 through the inlet fan 3, thereby improving the heat dissipation effect on electrical components and control equipment. The top side wall of the water-absorbing cotton 22 is fixedly connected to the inner pipe wall at the top of the air inlet pipe 2, and the water-absorbing cotton 22 is located between the inlet fan 3 and the air inlet 12. When the outside air enters the air inlet pipe 2, the air passes through the water-absorbing cotton 22, and at this time, the water-absorbing cotton 22 absorbs the water vapor in the air, thereby reducing the amount of water vapor entering the electric control application cabinet during heat dissipation.

[0031] A rotating shaft 31 is fixedly installed in the middle position of the air inlet fan 3. The rotating shaft 31 extends into the air inlet pipe 2 in the direction of the air inlet port 12. When the air inlet fan 3 rotates, the rotating shaft 31 is driven to rotate. A connecting column 21 is slidably connected to the vertical inner pipe wall on one side of the air inlet pipe 2. The connecting column 21 is a "T"-shaped structure, and the length direction of the connecting column 21 is parallel to the length direction of the air inlet pipe 2. The electric control application cabinet also includes a transmission component 4, which is arranged on the air inlet pipe 2. When the rotating shaft 31 rotates, the transmission component 4 drives the connecting column 21 to reciprocate up and down.

[0032] The transmission assembly 4 includes a rotating shaft 41, a rotating bevel gear 42, a transmission bevel gear 43, a transmission belt 44 and a first reciprocating screw 45. The first reciprocating screw 45 is rotatably connected to the air inlet pipe 2. The first reciprocating screw 45 extends in a vertical direction. The connecting column 21 is threadedly connected to the first reciprocating screw 45 and is perpendicular to each other.

[0033] The rotating shaft 41 is rotatably connected to the inner wall fan at the top of the air inlet duct 2, and the transmission bevel gear 43 is fixedly connected to the outer peripheral side of the rotating shaft 41. The rotating bevel gear 42 is fixedly connected to the outer peripheral side of the rotating shaft 31, and the rotating bevel gear 42 is meshed with the transmission bevel gear 43. When the rotating shaft 31 rotates, the rotating bevel gear 42 drives the rotating shaft 41 to rotate through the transmission bevel gear 43. The transmission belt 44 is connected end to end and is sleeved on the outer peripheral side of the rotating shaft 41 and the first reciprocating screw rod 45. When the rotating shaft 41 rotates, the first reciprocating screw rod 45 is driven to rotate through the transmission belt 44, and at this time, the first reciprocating screw rod 45 drives the connecting column 21 to reciprocate up and down.

[0034] The electric control application cabinet also includes a squeeze bar 23, which slides on the connecting column 21, extends in the horizontal direction and is perpendicular to the connecting column 21, and the length of the squeeze bar 23 is greater than the width of the absorbent cotton 22. There are two squeeze bars 23 and they are arranged opposite to each other, and the absorbent cotton 22 is located between the two opposite squeeze bars 23.

[0035] See also Figure 4 and Figure 5 The electric control application cabinet also includes a control component 5. When the extrusion strip 23 moves to the top wall of the air inlet pipe 2, the control component 5 controls the extrusion strip 23 to move closer to each other and the absorbent cotton 22; when the extrusion strip 23 moves to the bottom wall of the air inlet pipe 2, the control component 5 controls the extrusion strip 23 to move away from the absorbent cotton 22.

[0036] The control assembly 5 is disposed on the air inlet duct 2 , and includes a control spring 51 , a control block 52 , a driving spring 53 , a pushing block 54 , a control column 55 and a control rope 56 .

[0037] The two ends of the connecting column 21 are fixedly connected with the limiting blocks 211, and two control springs 51 are symmetrically arranged and respectively sleeved on the outer peripheral side of the connecting column 21. The two control springs 51 are respectively located between the extrusion strip 23 and the limiting blocks 211. One end of the control spring 51 abuts against the side of the extrusion strip 23 away from the absorbent cotton 22, and the other end abuts against the limiting blocks 211. When the control spring 51 is elastically released, it pushes the extrusion strip 23 to move toward the absorbent cotton 22, so that the two extrusion strips 23 cooperate with each other to squeeze the absorbent cotton 22, which is conducive to squeezing out the water vapor absorbed in the absorbent cotton 22.

[0038] Two control grooves are symmetrically provided on the connecting column 21, and each control groove is located between the extrusion strip 23 and the absorbent cotton 22. The control block 52 slides up and down in the control groove, and the control block 52 corresponds to the extrusion strip 23 one by one. The driving spring 53 is installed in the control groove, and the driving spring 53 corresponds to the control block 52 one by one. The top of the driving spring 53 abuts against the bottom of the control block 52, and the bottom of the driving spring 53 abuts against the bottom groove wall of the control groove. When the driving spring 53 is elastically released, the top part of the driving control block 52 protrudes out of the control groove. The top of the control block 52 is inclined to form a control surface 521, and the control surface 521 faces the absorbent cotton 22. When the squeezing strip 23 moves away from the absorbent cotton 22, the squeezing strip 23 slides on the control surface 521, pushing the control block 52 to slide into the control groove until the squeezing strip 23 passes the control block 52, and the driving spring 53 pushes the control block 52 to protrude out of the control groove. At this time, the side of the control block 52 away from the absorbent cotton 22 abuts against the squeezing strip 23, limiting the squeezing strip 23 from approaching the absorbent cotton 22.

[0039] The push block 54 is fixedly connected to the inner tube wall at the bottom of the air inlet pipe 2. The push block 54 corresponds to the extrusion strip 23 one by one. The top of the push block 54 is formed with an arc surface structure. The bottom of the extrusion strip 23 is inclined to form an extrusion surface 231, and the extrusion surface 231 faces the absorbent cotton 22. When the extrusion strip 23 approaches the tube wall at the bottom of the air inlet pipe 2, the push block 54 slides on the extrusion surface 231. At this time, the push block 54 pushes the extrusion strip 23 away from the absorbent cotton 22 until the extrusion strip 23 moves past the control block 52.

[0040] The control column 55 slides up and down on the limiting block 211 and corresponds one to one, and the top of the control block 52 protrudes out of the limiting block 211. The control rope 56 is slidably arranged in the limiting block 211 and the connecting column 21, and the control rope 56 corresponds one to one with the control column 55. One end of the control rope 56 is fixedly connected to the bottom of the control block 52, and the other end is fixedly connected to the outer wall of the control column 55. When the extrusion strip 23 moves upward and approaches the top wall of the air inlet pipe 2, the control column 55 abuts against the wall of the air inlet pipe 2 and slides toward the connecting column 21. At this time, the control rope 56 pulls the control block 52 to slide into the control groove, so that the driving spring 53 can push the extrusion strip 23 to move toward the absorbent cotton 22.

[0041] The electric control application cabinet also includes a water collecting box 6, which is fixed on the inner tube wall at the bottom of the air inlet pipe 2. A water inlet 61 is provided at the top of the water collecting box 6. The absorbent cotton 22 is located directly above the water inlet 61, and the bottom of the absorbent cotton 22 enters the water inlet 61. When the two squeezing bars 23 cooperate with each other to squeeze the absorbent cotton 22 and move downward, the squeezing bars 23 squeeze the water vapor absorbed in the absorbent cotton 22 into the water collecting box 6, so that the squeezed water vapor is collected in the water collecting box 6, which is conducive to maintaining the ability of the absorbent cotton 22 to absorb water vapor.

[0042] The air inlet pipe 2 is fixedly installed with a dust filter 24, which is located between the absorbent cotton 22 and the air inlet 12 (the air inlet 12 is located between the absorbent cotton 22 and the air inlet 12). Figure 2 The air entering the air inlet pipe 2 passes through the dust filter 24, and the dust in the air hole is filtered by the dust filter 24, which is helpful to reduce the amount of dust entering the installation cavity 11.

[0043] A water storage box 7 is embedded and fixed on the bottom tube wall of the air inlet pipe 2, and the water storage box 7 is located below the water collection box 6. A connection port 71 is provided on the top of the water storage box 7, and the connection port 71 is connected to the air inlet pipe 2. The bottom of the dust filter 24 passes through the connection port 71 and extends into the water storage box 7. The air inlet pipe 2 is fixedly connected with a connecting pipe, and the two ends of the connecting pipe are connected to the water collection box 6 and the water storage box 7 respectively. The connecting pipe extends downward from the water collection box 6 to the water storage box 7. When in use, the water flow collected in the water collection box 6 flows into the water storage box 7 through the connecting pipe, and then the water flow is absorbed by the dust filter 24, so that the dust filter 24 remains moist, which is conducive to improving the dust filtering ability of the dust filter 24.

[0044] See also Figure 6The inner tube wall of the vertical side of the air inlet pipe 2 is provided with a mounting block 25 that slides up and down. The inner wall of the air inlet pipe 2 is rotatably connected with a second reciprocating screw 26. The second reciprocating screw 26 is on the same side and parallel to the first reciprocating screw 45. The mounting block 25 is threadedly connected with the second reciprocating screw 26. The air inlet pipe 2 is provided with a linkage belt 27 that is connected end to end and sleeved on the outer circumference of the second reciprocating screw 26 and the first reciprocating screw 45. When the first reciprocating screw 45 rotates, the second reciprocating screw 26 is driven to rotate through the linkage belt 27, so that the mounting block 25 reciprocates up and down.

[0045] See also Figure 7 and Figure 8 A cleaning roller 8 is rotatably connected to the mounting block 25, and a plurality of cleaning bristles 81 are evenly spaced and fixed on the outer circumference of the cleaning roller 8. A power gear 82 is fixedly connected to the outer circumference of the cleaning roller 8, and a power rack 83 is fixedly connected to the inner tube wall of the vertical side of the air inlet pipe 2 (the power rack 83 is fixedly connected to the inner tube wall of the vertical side of the air inlet pipe 2). Fig. 9 The power rack 83 extends in the vertical direction, and the power gear 82 is meshed with the power rack 83.

[0046] See also Fig. 9 and Fig.10 , when the installation block 25 (installation block 25 in Figure 7 When the mounting block 25 moves up and down, the power rack 83 is driven by the power gear 82 to rotate, so that the cleaning bristles 81 are slidably connected to the side of the dust filter 24 away from the water-absorbing cotton 22, which is conducive to reducing the amount of dust on the dust filter 24 and improving the dust filtering effect of the dust filter 24. And when the mounting block 25 moves downward, the cleaning roller 8 can enter the water storage box 7, so that the water flow in the water storage box 7 wets the cleaning bristles 81, reducing the possibility of dust floating around when the dust filter 24 is cleaned.

[0047] See also Figure 7 and Figure 8 The mounting block 25 is rotatably connected with a water storage pipe 88, and a receiving groove 84 is formed in the cleaning roller 8, and the water storage pipe 88 is located in the receiving groove 84. The water storage pipe 88 is coaxially arranged with the cleaning roller 8, and the peripheral groove wall of the receiving groove 84 is slidably connected with the outer wall of the water storage pipe 88.

[0048] A water inlet 85 is provided in the middle of one end of the cleaning roller 8 away from the mounting block 25, and the water inlet 85 is aligned with and connected to the water storage pipe 88. A water outlet 89 is formed on the bottom wall of the water storage pipe 88, and there are multiple water outlets 89 and they are evenly spaced along the axial direction.

[0049] The roller wall of the cleaning roller 8 is formed with a water delivery hole 87, which is connected to the connecting groove 86. There are multiple water delivery holes 87 and they correspond one to one with the connecting groove 86. When the water delivery hole 87 is at the top position of the cleaning roller 8, the water outlet hole 89 is at the bottom position of the water storage pipe 88.

[0050] See also Fig. 9 and Fig.10 , installation block 25 (installation block 25 in Figure 7 The water storage pipe 88 is provided with a driving assembly 9. When the cleaning roller 8 rotates, the driving assembly 9 drives the water storage pipe 88 to rotate in the opposite direction to the cleaning roller 8. The driving assembly 9 includes a driving rack 91, a connecting gear 92 and a transmission rack 93. The driving rack 91 is an annular structure and is fixedly connected to the peripheral groove wall of the receiving groove 84. The outer peripheral side wall of the water storage pipe 88 is formed with a mounting groove 881 extending in the circumferential direction (the mounting groove 881 is at Figure 7 As shown in the figure, the transmission rack 93 is fixedly connected to the groove wall of the mounting groove 881 away from the groove opening, and there is a distance between the driving rack 91 and the transmission rack 93.

[0051] The mounting block 25 is rotatably connected to a support shaft, and the support shaft extends between the driving rack 91 and the transmission rack 93. The connecting gear 92 is fixedly connected to the support shaft, and the connecting gear 92 is respectively meshed with the driving rack 91 and the transmission rack 93. When the cleaning roller 8 rotates, the driving rack 91 rotates through the connecting gear 92, so that the connecting gear 92 can drive the water storage pipe 88 to rotate through the transmission rack 93, and the rotation direction between the water storage pipe 88 and the cleaning roller 8 is opposite.

[0052] See also Figure 8 and Fig. 9 When the cleaning roller 8 enters the water storage box 7, the water in the water storage box 7 enters the water storage pipe 88, and the water in the water storage pipe 88 enters the connecting groove 86 through the water outlet hole 89, so that there is water in the connecting groove 86 at the bottom of the cleaning roller 8, and the water delivery hole 87 is at the top position of the cleaning roller 8. Then, during the upward movement of the cleaning roller 8, the water storage pipe 88 rotates, so that the water outlet hole 89 moves from the bottom position of the water storage pipe 88 to the top position; and the water delivery hole 87 moves from the top position of the cleaning roller 8 to the bottom position. During the movement, the water in the connecting groove 86 flows out through the water delivery hole 87 to the surface of the cleaning roller 8, cleaning and moistening the cleaning bristles 81, improving the cleaning effect of dust; and part of the water flows along the cleaning bristles 81 to moisten the cleaning net, improving the filtering effect of dust. When the water supply hole 87 outputs the water flow in the connecting groove 86, the water outlet hole 89 is away from the water supply hole 87, so that the water flow in the water storage pipe 88 cannot temporarily enter the connecting groove 86 through the water outlet hole 89, which is beneficial to improve the utilization rate of the water flow in the water storage pipe 88 and reduce the possibility of waste due to excessive amount of water flowing to the surface of the cleaning roller 8.

[0053] The implementation principle of an electric control application cabinet in the embodiment of the present application is: When in use, the air inlet fan 3 is started, so that the outside air forms an airflow through the air inlet pipe 2 and enters the installation cavity 11 to dissipate heat for the electrical components and control equipment. At the same time, when the airflow passes through the air inlet pipe 2, the dust filter 24 filters the dust in the airflow, and the absorbent cotton 22 absorbs the water vapor in the airflow, so that the dust, water vapor and water flow in the airflow entering the installation cavity 11 are reduced, and the possibility of water vapor and dust affecting the electrical components and control equipment is reduced.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
