Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, in particular to an electrical cabinet that can be used in dusty places. Background Art

[0002] The electrical cabinet is made of steel and is used to protect the normal operation of components. It is a power distribution control that distributes electrical energy to various load parts and performs power-off protection when the circuit is short-circuited, overloaded, or leaking. Dust is solid microparticles floating in the air. Dust in dusty places can float in the air for a long time. Solid particles can easily diffuse and flow in the air through gas flow;

[0003] In the "Electrical Control Cabinet for Dust-Prone Places" with the patent CN212812455U, dust covers and dust caps are installed in the electrical control group and the arrangement area of ​​the wires for dust prevention, and a radiator and a heat conducting plate are installed on the mounting substrate to form a heat dissipation assembly to cooperate with the circulating fresh air to extract the heat generated by the electrical control assembly fixed on the mounting substrate when it is powered on, so as to avoid heat accumulation affecting the service life of the device. However, when the electrical cabinet is used, the dust floating in the air will be blocked in the heat dissipation mesh of the electrical cabinet due to the flow. Long-term use will cause the heat dissipation mesh of the distribution cabinet to be blocked, which will not only cause the heat inside the electrical cabinet to be unable to be dissipated, but also cause the electrical components inside the cabinet to malfunction and be damaged due to high temperature, which is not convenient for the stable use of the electrical cabinet in the later stage.

[0004] Therefore, we propose an electrical cabinet that can be used in dusty places to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an electrical cabinet that can be used in dusty places, so as to solve the problem raised by the above-mentioned background technology that the dust floating in the air in the current market will be blocked in the heat dissipation mesh holes of the electrical cabinet due to flow, and long-term use will cause the heat dissipation mesh holes of the distribution cabinet to be blocked, which will not only cause the heat inside the electrical cabinet to be unable to dissipate, but also cause the electrical components inside the cabinet to malfunction and be damaged due to high temperature, which is not convenient for the stable use of the electrical cabinet in the later stage.

[0006] To achieve the above object, the present invention provides the following technical solutions: an electrical cabinet that can be used in dusty places, comprising a base, a cabinet body, a closing door, a heat dissipation net, a top plate, a support rod and a mounting frame;

[0007] A base, on which a cabinet is installed, and a closing door is installed on the front hinge of the cabinet, and both sides of the inner wall of the cabinet are grooved and provided with a heat dissipation net;

[0008] It also includes: both ends of the top of the cabinet are slotted and connected with support rods, and the structures of the two support rods are the same, and the upper parts of the two support rods extend to the outer sides of the upper ends of the cabinet, and the upper parts of the two support rods are connected with a top plate, and the width of the top plate is greater than the length of the cabinet, and an alarm is screwed on the top of the top plate;

[0009] The cabinet is provided with an installation frame installed by slotted screws inside the cabinet, and a row of electrical components is installed on the surface of the installation frame, and connecting rods are installed on the outer sides of both ends of the installation frame, and the two connecting rods are symmetrically arranged about the vertical center line of the installation frame, and rotating rods are installed with bearings at both ends of the base, and the structures of the two rotating rods are identical, and the two rotating rods are both penetrated and connected with a filter plate, wherein the filter plate is installed on the inner side of the bottom of the cabinet, and there is a corresponding installation frame above the filter plate.

[0010] Preferably, a servo motor is installed with screws on the inner side of the bottom of the cabinet, and a cooling fan is installed at the output end of the servo motor, and a filter plate is correspondingly provided above the cooling fan. The output end of the servo motor is connected to two rotating rods through two first connecting belts, which can drive the two rotating rods to rotate at the same time. The cooling fan is installed at the output end of the servo motor, which can drive the cooling fan to blow and transport the heat inside the cabinet.

[0011] Preferably, the outer ends of the two connecting rods are meshedly connected to the rotating rod via the first bevel gear set, and the outer ends of the two connecting rods are fixedly installed with cleaning brush rods, and the outer sides of the two cleaning brush rods are fit connected to the inner wall of the heat dissipation net. By utilizing the fact that the outer ends of the two connecting rods are meshedly connected to the rotating rod via the first bevel gear set, and the outer ends of the two connecting rods are fixedly installed with cleaning brush rods, the inner sides of the two heat dissipation nets can be scraped and cleaned reciprocally by the two cleaning brush rods, thereby avoiding the phenomenon that the two heat dissipation nets are blocked by external dust.

[0012] Preferably, the tops of the two rotating rods are meshed with a rotating shaft through a second bevel gear set, and half gears are installed through the rear ends of the two rotating shafts, and the structures of the two half gears are identical, the outer sides of the two half gears are meshed with support rods through a row of tooth blocks, and the two rows of tooth blocks are equidistantly arranged on the outer sides of the two support rods, and a sealing plate is installed through a groove on the top upper part of the cabinet body through the rotation of the shaft, and the sealing plate is connected to the bottom of the sealing plate through a pull rope, and the half gears are installed through the rear ends of the rotating shafts, which can drive the support rods meshed with the outer sides of the two half gears to move back and forth.

[0013] Preferably, the inner groove of the sealing plate is provided with a second torsion spring, and the outer side of the second torsion spring is wound and connected to the outer side of the shaft rod. The inner groove of the sealing plate is provided with a second torsion spring, and the outer side of the second torsion spring is wound and connected to the outer side of the shaft rod. The second torsion spring can be used to elastically reset the sealing plate after being flipped, which is more convenient for stable heat dissipation of the heat inside the cabinet in the later stage.

[0014] Preferably, a row of mounting frames are installed on the inner groove of the bottom of the mounting frame, and the inner sides of the row of mounting frames are all grooved and slidably connected with screening plates, and the inner sides of the screening plates are provided with holes and grooves through which wiring harnesses are connected, and mounting shafts are grooved at both ends of the inside of the mounting frames, and the outer sides of the two mounting shafts are slidably connected with screening plates through first torsion springs. By utilizing the outer sides of the mounting shafts to be slidably connected with the screening plates through the first torsion springs, the elastic force of the first torsion springs themselves can be used to conveniently elastically reset the position of the screening plate after pulling.

[0015] Preferably, a single-rotation reciprocating screw is installed on the upper bearing of the filter plate, and the outer bottom side of the single-rotation reciprocating screw is connected to the rotating rod at the left end through a second connecting belt. The upper thread of the rotating rod is penetrated by a temperature monitor, and the rear end of the temperature monitor is slidably connected to the inner wall of the cabinet. The outer bottom side of the single-rotation reciprocating screw is connected to the rotating rod at the left end through the second connecting belt, which can drive the temperature monitor to perform reciprocating monitoring of the heat inside the cabinet to prevent high temperature from affecting the stable use of electrical components.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) A rotating rod, a first bevel gear set, a connecting rod and a cleaning brush rod are provided. The rotating rod is installed by means of slotted bearings at both ends of the cabinet body. Then, the output end of the servo motor is connected to the bottom of the two rotating rods through a first connecting belt. Then, the two rotating rods can be driven to rotate through the first bevel gear set at the same time. At this time, the two cleaning brush rods can be driven to reciprocately clean and scrape the inner wall of the heat dissipation net on both sides of the heat dissipation net cabinet body, so as to prevent external dust from penetrating into the interior of the cabinet body through the two heat dissipation nets and affecting the stable use of its internal electrical components in the later stage.

[0018] (2) A support rod, a sealing plate, a pull rope and a half gear are provided. The two rotating rods are meshed with a rotating shaft through a second bevel gear set, which can simultaneously drive the half gears installed at the rear ends of the two rotating shafts to mesh with the support rods through two rows of gear blocks, and then the top plate connected to the top of the two supporting rods can be driven to lift and lower back and forth. At this time, the top plate will pull the sealing plate back and forth through the pull rope to flip, and then the cooling fan will discharge the heat inside the cabinet to its outside, avoiding the high heat inside the cabinet affecting the stable use of electrical components. Finally, the elastic force of the second torsion spring itself can be used to elastically reset the position of the flipped top plate, which is more convenient for the stable use of the cabinet.

[0019] (3) A single-rotation reciprocating screw, a second connecting belt and a temperature monitor are provided. The single-rotation reciprocating screw is installed on a slotted bearing on the inner side of the bottom of the cabinet, and then a rotating rod is connected to the bottom of the single-rotation reciprocating screw through the second connecting belt, which can drive the temperature monitor connected to the outer thread of the single-rotation reciprocating screw to move back and forth up and down. Because the rear side of the temperature monitor is slidably connected to the inner wall of the cabinet, the temperature monitor can be slidably limited, so that the temperature inside the cabinet can be better monitored and used more evenly through the temperature monitor.

[0030] See also Figure 1-Figure 8 The present invention provides a technical solution: an electrical cabinet that can be used in dusty places, comprising a base 1, a cabinet body 2, a closing door 3, a heat dissipation net 4, a top plate 5, a support rod 6, a mounting frame 7, a rotating rod 8, a servo motor 9, a heat dissipation fan 10, a first connecting belt 11, a first bevel gear set 12, a connecting rod 13, a cleaning brush rod 14, a sealing plate 15, a pull rope 16, a filter screen 17, a single-rotation reciprocating screw rod 18, a second connecting belt 19, a temperature monitor 20, a second bevel gear set 21, a rotating shaft 22, a half gear 23, a mounting frame 24, a screening plate 25, a first torsion spring 26, a second torsion spring 27 and a filter plate 28;

[0031] A base 1, on which a cabinet 2 is installed, and a closing door 3 is installed on the front hinge of the cabinet 2, and both sides of the inner wall of the cabinet 2 are grooved with a heat dissipation net 4;

[0032] It also includes: both ends of the top of the cabinet 2 are slotted and penetrated with support rods 6, and the structures of the two support rods 6 are the same, and the upper parts of the two support rods 6 penetrate and extend to the outer sides of the upper ends of the cabinet 2, and the upper parts of the two support rods 6 are connected with a top plate 5, and the width of the top plate 5 is greater than the length of the cabinet 2, and an alarm is screwed on the top of the top plate 5;

[0033] The cabinet body 2 is provided with a mounting frame 7 by means of slotted screws inside the cabinet body 2, and a row of electrical components is mounted on the surface of the mounting frame 7, and connecting rods 13 are mounted on the outer sides of both ends of the mounting frame 7, and the two connecting rods 13 are symmetrically arranged about the vertical center line of the mounting frame 7, and rotating rods 8 are mounted on bearings on both ends of the interior of the base 1, and the structures of the two rotating rods 8 are identical, and the two rotating rods 8 are both penetrated and connected with a filter plate 28, wherein the filter plate 28 is mounted on the inner side of the bottom of the cabinet body 2, and the mounting frame 7 is provided above the filter plate 28.

[0034] A servo motor 9 is screwed on the inner side of the bottom of the cabinet 2, and a cooling fan 10 is installed on the output end of the servo motor 9, and a filter plate 28 is correspondingly arranged above the cooling fan 10. The output end of the servo motor 9 is connected to two rotating rods 8 through two first connecting belts 11, which can drive the two rotating rods 8 to rotate at the same time. Figure 1 , Figure 2 and Figure 7 As shown, when the cabinet 2 needs to regularly clean and wipe the heat dissipation nets 4 on both sides of the cabinet 2, start the servo motor 9 to simultaneously drive the two rotating rods 8 to rotate through the two first connecting belts 11, and then the cleaning brush rods 14 installed on the outside of the two connecting rods 13 can be driven by the two first bevel gear sets 12 to reciprocately clean and scrape the inner walls of the two heat dissipation nets 4 to prevent external dust from penetrating into the inner wall of the cabinet 2 through the heat dissipation net 4 and causing the stable use of the cabinet 2.

[0035] The outer ends of the two connecting rods 13 are meshedly connected to the rotating rod 8 through the first bevel gear set 12, and the outer ends of the two connecting rods 13 are fixedly installed with cleaning brush rods 14, and the outer sides of the two cleaning brush rods 14 are both fitted and connected to the inner wall of the heat dissipation net 4, and the tops of the two rotating rods 8 are meshedly connected to the rotating shaft 22 through the second bevel gear set 21, and the rear ends of the two rotating shafts 22 are penetrated and installed with half gears 23, and the structures of the two half gears 23 are identical, and the outer sides of the two half gears 23 are meshedly connected to the supporting rod 6 through a row of tooth blocks, and the two rows of tooth blocks are equidistantly arranged on the outer sides of the two supporting rods 6, and the sealing plate 15 is installed on the upper groove of the top of the cabinet 2 through the shaft, and the bottom of the sealing plate 15 is connected to the sealing plate 15 through a pull rope 16. Figure 1-Figure 6 As shown, while the two rotating rods 8 are rotating, the two second bevel gear sets 21 can drive the half gears 23 installed at the rear ends of the two rotating shafts 22 to rotate. Because the outer ends of the two half gears 23 are meshed with the support rods 6 through a row of gear blocks, the installation frame 7 connected above the two support rods 6 can be driven to drive the sealing plate 15 to reciprocate through the pull rope 16. At this time, the cooling fan 10 can quickly disperse the heat inside the cabinet 2 to the outside of the cabinet 2, avoiding the phenomenon that the electrical components fail due to high temperature.

[0036] The inner groove of the sealing plate 15 is provided with a second torsion spring 27, and the outer side of the second torsion spring 27 is wrapped and connected to the outer side of the shaft rod. Finally, the elastic force of the second torsion spring 27 itself can elastically reset the flipped sealing plate 15 to prevent external dust from penetrating into the interior of the cabinet 2.

[0037] The bottom inner side of the mounting frame 7 is slotted with a row of mounting frames 24, and the inner sides of the row of mounting frames 24 are all slotted with a slidable connection to a screening plate 25, and the inner side of the screening plate 25 is provided with a hole slot through which a wiring harness is connected, and both ends of the mounting frame 24 are slotted with mounting shafts, and the outer sides of the two mounting shafts are both slidably connected to the screening plate 25 through the first torsion spring 26, such as Figure 2 , Figure 5 and Figure 8 As shown, when the electrical components inside the cabinet 2 are replaced and repaired, the screening plate 25 can be pulled to sort out and screen the wiring harnesses that are connected inside, so as to avoid the wiring harnesses from being entangled when they are disassembled and repaired. Finally, the elastic force of the first torsion spring 26 itself can be used to elastically reset the position of the screening plate 25 after movement, so as to better assist the stable use of the electrical components.

[0038] A single-rotation reciprocating screw 18 is installed on the upper bearing of the filter plate 28, and the bottom outer side of the single-rotation reciprocating screw 18 is connected to the rotating rod 8 at the left end through a second connecting belt 19. The upper thread of the rotating rod 8 is penetrated by a temperature monitor 20, and the rear end of the temperature monitor 20 is slidably connected to the inner wall of the cabinet 2. Then the second connecting belt 19 can be used to simultaneously drive the outer thread of the single-rotation reciprocating screw 18 to penetrate the temperature monitor 20 for position lifting and moving monitoring. When the temperature inside the cabinet 2 is too high, the temperature monitor 20 will transmit the monitored information to the alarm, and then the alarm will sound an alarm to remind nearby staff to deal with it in time, which is more convenient for the stable use of the cabinet 2 in the later stage.

[0039] The working principle of this embodiment: when using the electrical cabinet that can be used in dusty places, first, start the servo motor 9 and drive the two rotating rods 8 to rotate at the same time through the two first connecting belts 11, and then drive the cleaning brush rods 14 installed on the outside of the two connecting rods 13 to reciprocate and scrape the inner walls of the two heat dissipation nets 4, and the two heat dissipation nets 4 can be regularly cleaned and wiped of dust.

At this time, the cooling fan 10 can quickly disperse the heat inside the cabinet 2 to the outside of the cabinet 2, and then pull the screening plate 25 to comb and screen the wire harness connected inside it, and finally use the elastic force of the first torsion spring 26 itself to elastically reset the position of the moving screening plate 25, and then use the second connecting belt 19 to simultaneously drive the outer thread of the single-rotation reciprocating screw 18 to penetrate and connect the temperature monitor 20 for position lifting and moving monitoring. When the temperature inside the cabinet 2 is too high, the temperature monitor 20 will transmit the monitored information to the alarm, and then the alarm will sound an alarm to remind nearby staff to deal with it in time.
