Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and cleaning of electrical control boxes, and specifically relates to a self-cleaning electrical control box. Background Technique

[0002] A control box is a device 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 electrical wiring requirements. Its layout should meet the requirements for the normal operation of the power system, be convenient for maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be connected or disconnected manually or automatically through a switch. In case of a fault or abnormal operation, the circuit is cut off or an alarm is given by means of a protective electrical appliance. Various parameters during operation can be displayed by measuring instruments, and some electrical parameters can also be adjusted to prompt or send signals for deviations from the normal working state.

[0003] Currently, most electrical cabinets on the market are in the shape of a cabinet body. Since electrical components need breathable grilles for heat dissipation, dust will enter the electrical cabinet, resulting in dust deposition. Without a good dust removal device, the electrical components inside the electrical cabinet are covered with dust, which easily affects the normal operation of the electrical components inside the electrical cabinet. This requires manual cleaning of the inside of the electrical control box regularly, which is rather troublesome.

[0004] After retrieval, a self-cleaning electrical control box disclosed in Chinese Patent Publication No. CN117277114A. The problem to be solved by this utility model is that electrical components need breathable grilles for heat dissipation, dust will enter the electrical cabinet, resulting in dust deposition. Without a good dust removal device, the electrical components inside the electrical cabinet are covered with dust, which easily affects the normal operation of the electrical components inside the electrical cabinet. This requires manual cleaning of the inside of the electrical control box regularly, which is rather troublesome. This utility model consists of a lifting air blowing mechanism and a suction mechanism. In this self-cleaning electrical control box, when the electric telescopic rod extends, it pushes the U-shaped rod to move upward, causing the sealing plate at the other end of the sliding plate to separate from the fixed frame, ensuring that the through slots on one side of the fixed frame are opened. Then, through the rotation of the exhaust fan, the air outside is guided along the two through slots into the interior of the box body, and then the dust-containing gas blown forward by the exhaust fan is inhaled into the interior of the contraction airbag, achieving the purpose of purifying the air inside the box.

[0005] The above patent combines the actual need for a self-cleaning electrical control box and has the following problems: 1. The technical solution in the above patent uses "the gear shaft 46 rotates in cooperation with the toothed plate 45 and drives the exhaust fan 422 to rotate through the transmission belt, guiding the air outside along the two through slots 418 into the interior of the box body 1". Considering the limitation of the internal space of the electrical control box in actual operation, using the power of the gear shaft meshing with the toothed plate to drive the rotation of the exhaust fan cannot generate enough power to guide the air outside along the two through slots into the interior of the box body, resulting in the problem of low gas purification efficiency inside the box.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1

[0031] Please refer to Figures 1-7As shown in the figure, a self-cleaning electric control box includes a box body 1 and a grille plate seat 2 installed inside the box body 1; the grille plate seat 2 includes side plates 21, an installation grille 22 and a cycloidal grille 23 installed on the side plates 21. The installation grille 22 is used to install existing electrical components, and the cycloidal grille 23 is used to position the wiring of the components. A plurality of convex balls 24 distributed in an array are fixedly connected to the inner wall surface of the side plates 21, and a ventilator seat 3 installed on the top of the box body 1; a double-fan two-way ventilation device 4 provided on the box body 1, and a power device 5 for driving the rotation of the fan blades in the double-fan two-way ventilation device 4. A protective top cover for assisting the safe intake and exhaust of the box body 1 is installed on the top of the box body 1.

[0032] In addition, the power device 5 includes a driving motor 51 installed in the ventilator seat 3. A main transmission wheel 52 is connected to the output shaft of the driving motor 51. The main transmission wheel 52 is connected to a sub-transmission wheel 53 through a belt drive. A magnetic drive disk 54 is fixedly connected to the sub-transmission wheel 53. A fixed base 55 is rotatably connected to the connection part of the magnetic drive disk 54 and the sub-transmission wheel 53, and the fixed base 55 is fixedly connected to the inside of the ventilator seat 3.

[0033] In this embodiment, the double-fan two-way ventilation device 4 includes an installation frame 41 installed on the top of the box body 1, a filtration switching device 49, and a mobile blowing and suction device 410. A switching motor 42 is installed on the installation frame 41. The output shaft of the switching motor 42 is connected to a crankshaft 43. The end of the crankshaft 43 is slidably connected to a connection sliding seat 44. The connection sliding seat 44 is respectively rotatably connected to a positive-pressure fan 46 and a negative-pressure fan 47 through a connection frame 45. Magnetic passive disks 48 are connected to both the positive-pressure fan 46 and the negative-pressure fan 47. A plurality of magnets are arranged on the magnetic passive disks 48 in a circular array distribution, and the plurality of magnets are distributed in a staggered state of positive and negative polarities. The magnetic passive disks 48 are magnetically connected to the magnetic drive disk 54. By driving the crankshaft 43 to rotate 180 degrees by the switching motor 42 to drive the connection frame 45 on the connection sliding seat 44 to move, the effect of adjusting the positions of the positive-pressure fan 46 and the negative-pressure fan 47 by the connection frame 45 is realized. After the magnetic passive disks 48 on different fans are magnetically driven by the magnetic drive disk 54, the driving directions of the airflows are also different. Different airflows act inside the box body 1, and the effect of switching the intake and exhaust functions of the box body 1 can be achieved.

[0034] Furthermore, sliding wheels for support and movement are installed on the connection sliding seat 44.

[0035] Furthermore, the filtering switching device 49 includes a plurality of filter net plates 491 that are array - distributed and rotate inside the ventilator base 3, a driving plate 493 fixed on the connecting sliding seat 44. One end of the filter net plate 491 that penetrates through the ventilator base 3 is fixedly connected with a passive rod 492. A torsion spring is arranged on the axial surface where the filter net plate 491 rotates inside the ventilator base 3. The elastic force of the torsion spring controls the filter net plate 491 to be in contact with the adjacent filter net plates 491 in the normal state, forming a closed - mesh filter net surface to filter the gas flowing through the mesh surface end, thereby achieving the effect of preventing impurities from entering the inside of the box body 1. A folded - type active rod 494 for driving the passive rod 492 to rotate is fixedly connected to the driving plate 493. When the negative - pressure fan 47 is about to switch to the inside of the ventilator base 3, the moving connecting sliding seat 44 will drive the folded - type active rod 494 to move through the driving plate 493. During the movement of the folded - type active rod 494, it drives the passive rod 492 by extrusion contact, achieving the effect of driving the filter net plate 491 to rotate. When the connecting sliding seat 44 is fixed after moving, multiple folded - type active rods 494 are used to drive the filter net plate 491 to maintain a state perpendicular to the top surface of the ventilator base 3. At this time, the opened filter net plate 491 can facilitate the box body 1 to suck out the internal dust from the inside to the outside, further assisting the box body 1 in self - cleaning work.

[0036] It should be noted that the moving blowing and sucking device 410 includes a reciprocating lead screw 411. The top end of the reciprocating lead screw 411 is fixedly connected to the bottom end of the main transmission wheel 52. A moving base 412 is slidably connected to the surface of the reciprocating lead screw 411. A communicating seat 413 is elastically connected inside the moving base 412 through a torsion spring. When the main transmission wheel 52 rotates, it drives the moving base 412 on the reciprocating lead screw 411 to move linearly inside the box body 1. When the communicating seat 413 moves, the lower surface of the communicating seat 413 will intermittently contact the convex ball 24 on the side plate 21. When it contacts the convex ball 24, it will make an elastic rotational yield, and when it moves away from the convex ball 24, it will make an elastic reset rotation. That is, during the up - and - down movement of the communicating seat 413 inside the box body 1, it synchronously makes intermittent rotational movements, achieving the effect of quickly and efficiently blowing and sucking air for the electrical components installed on the installation grille 22 inside the box body 1. At the same time, the moving communicating seat 413 can work on the electrical components at different positions, thereby improving the working efficiency of the communicating seat 413 itself.

[0037] It should be noted that a ventilation slot is opened at the top of the box body 1. A diversion base 414 is fixedly connected to the top inner wall of the box body 1 at the ventilation slot. The bottom end of the diversion base 414 is connected with a telescopic tube 415. The movable bottom end of the telescopic tube 415 is fixedly connected to the communicating seat 413. The telescopic tube 415 is used to connect the communicating seat 413 and the diversion base 414, and at the same time has a telescopic effect to meet the connection effect between the communicating seat 413 and the diversion base 414 during the movement of the communicating seat 413.

[0038] When the self-cleaning electric control box of the utility model is in use, the operation of the switching motor 42 and the driving motor 51 is controlled by the central controller. In the initial state, as Figures 1-7 shown, when the driving motor 51 rotates, the output shaft of the driving motor 51 will drive the magnetic driving disc 54 on the main driving wheel 52 and the belt transmission secondary driving wheel 53 to rotate through the main driving wheel 52. When the magnetic driving disc 54 rotates, it will magnetically drive the magnetic passive disc 48 through the magnets with positive and negative pole directions arranged in an array and staggered on it. The magnetic passive disc 48 transmits the power to the positive pressure fan 46, realizing that the positive pressure fan 46 rotates to generate positive pressure gas flowing from the outside of the box body 1 to the inside of the ventilation machine base 3, and the gas acts on the communication seat 413 from the inner telescopic pipe 415 through the diversion base 414 connected to the ventilation machine base 3. The communication seat 413 is aligned with the installation grille 22, realizing the effect of introducing air from the outside of the box body 1 into the inside of the box body 1, and then realizing the effect of ventilating and cooling the inside of the box body 1 under normal circumstances. At the same time, when the main driving wheel 52 rotates, the rotational force will act on the moving base 412 through the reciprocating screw rod 411. The moving base 412 can only move linearly due to the limitation of the internal space of the box body 1. When the moving base 412 drives the communication seat 413 to move and blow air inside the box body 1, the communication seat 413 will intermittently contact the convex ball 24 on the side plate 21. When it contacts the convex ball 24, it will perform elastic rotational yielding, and perform elastic reset rotation after leaving the convex ball 24. That is, during the up and down movement of the communication seat 413 inside the box body 1, it performs intermittent rotational movement, so as to realize the effect of the communication seat 413 moving and rotating to blow air, and realize the effect of quickly and efficiently ventilating and cooling the electrical components installed on the installation grille 22 inside the box body 1. At the same time, the moving communication seat 413 can work on the electrical components in different positions, thereby improving the working efficiency of the communication seat 413 itself. When the positive pressure fan 46 is working, the filter plates 491 distributed in a linear array realize the filtration of the gas, thereby avoiding the problem that external impurities enter the box body 1 and affect the operation of the internal components.

[0039] When it is necessary to regularly perform self-cleaning on the box body 1, only need to control the operation of the switching motor 42. The output shaft of the switching motor 42 drives the crankshaft 43 to rotate 180 degrees. During the rotation of the crankshaft 43, the connecting slide 44 drives the two fans on the connecting frame 45 to move. The positive pressure fan 46 moves out of the ventilator base 3, and the negative pressure fan 47 moves into the ventilator base 3. And the magnetic passive disk 48 on the negative pressure fan 47 corresponds to the position of the magnetic drive disk 54. At this time, start the drive motor 51 again. The rotating magnetic drive disk 54 drives the negative pressure fan 47 to work through the magnetic passive disk 48. The negative pressure acts on the communication seat 413 through the diversion base 414 and the telescopic pipe 415. As the movement state of the communication seat 413 during the operation of the positive pressure fan 46 above. At this time, the communication seat 413 moves and rotates to pump air inside the box body 1. The communication seat 413 is aligned with the electrical components on the installation grille 22 to pump air, and then the effect of dust suction cleaning on its surface is realized. The dust is discharged from the inside of the box body 1 through the negative pressure from the communication seat 413, further achieving the effect of automatic self-cleaning inside the box body 1. And the fan blades located at the top of the box body 1 driven by magnetic force are not restricted by the internal space of the box body 1, and can generate the maximum air pressure, so as to act on the inside of the box body 1 efficiently, realizing effective and efficient ventilation and cleaning work.

[0040] Among them, when the negative pressure fan 47 is about to switch to the inside of the ventilator base 3, the moving connecting slide 44 will drive the folded active rod 494 to move through the drive plate 493. During the movement of the folded active rod 494, it drives the filter net plate 491 to rotate by squeezing the contact passive rod 492. And when the connecting slide 44 is fixed after moving, multiple folded active rods 494 are used to drive the filter net plate 491 to maintain a state perpendicular to the top surface of the ventilator base 3. The filter net plates 491 that originally contacted each other to form a closed net surface no longer filter the gas at the ventilator base 3 after rotation. At this time, the open filter net plate 491 can facilitate the effect of sucking the internal miscellaneous dust out of the box body 1 from the inside to the outside, further assisting the box body 1 in self-cleaning work.

[0041] The overall technical solution is different from the traditional single-fan setting. It adopts positive and negative pressure double-position fans, and uses the switching of the fans to realize the switching effect of the air intake and exhaust functions inside the box body 1, greatly improving the functional effect of the fans in the electrical control box, and realizing the comprehensive and sufficient ventilation and self-cleaning effects on the box body. The fan blades located at the top of the box body 1 driven by magnetic force are not restricted by the internal space of the box body 1, and can generate the maximum air pressure, so as to act on the inside of the box body 1 efficiently, realizing effective and efficient ventilation and cleaning work.
