Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinet cleaning, and more specifically, to a self-cleaning power distribution cabinet. Background Art

[0002] The power distribution cabinet is a general term for the motor control center. It is used in places where the load is relatively dispersed and there are fewer circuits. It distributes the power of a circuit of the upper-level distribution equipment to the nearest load. After long-term use, a lot of dust will accumulate on the electronic components inside the distribution cabinet, affecting the heat dissipation effect of the electronic components.

[0003] Most of the existing distribution cabinets use cooling fans and filters to achieve ventilation and heat exchange inside the distribution cabinet. The filter cannot completely filter out fine dust in the air. During the heat dissipation process, fine particles of dust will enter the cabinet with the airflow. At the same time, during the installation and maintenance of electronic components, the cabinet door needs to be opened, and dust in the air will enter the cabinet. Therefore, during actual use, even with the presence of a filter, there will still be a lot of dust in the cabinet, which poses a safety hazard to the heat dissipation and use of electronic components. At the same time, after the filter has been used for a long time, there are many blockages on the surface of the filter, which makes the ventilation of the filter cylinder worse, thereby affecting the normal heat dissipation inside the distribution cabinet, and the filter needs to be cleaned frequently. Summary of the invention

[0041] A self-cleaning power distribution cabinet, specifically, comprises a cabinet body 1 with a sealed top; a filter barrel 2 coaxial with the cabinet body 1 is fixed on the top of the cabinet body 1; a plurality of partitions 3 are evenly fixed between the filter barrel 2 and the inner wall of the cabinet body 1; the bottom end of the filter barrel 2 is open, and a cleaning portion 4 is slidably arranged on the peripheral side surface; guide columns 5 are symmetrically fixed on the two opposite sides of each partition plate 3; partition components 6 compatible with the corresponding guide columns 5 are symmetrically slidably arranged on the two opposite sides of each partition plate 3; the partition component 6 comprises a sliding portion and a rotating portion rotatably arranged on the sliding portion; a baffle plate 8 is evenly fixed on the top of the cabinet body 1; sealing grooves 9 symmetrically arranged on the side of the baffle plate 8 for plugging and matching with the rotating portion; a plurality of ash outlets 10 are evenly arranged on the bottom surface of the cabinet body 1; an exhaust assembly 11 is installed on the bottom of the cabinet body 1; a guide portion 12 is rotatably arranged between the exhaust assembly 11 and the cabinet body 1; a plurality of first installation openings 13 are evenly arranged on the peripheral side surface of the cabinet body 1, and a rotating door 14 is rotatably arranged on the outer peripheral side surface.

[0042] Working principle of the first embodiment:

[0043] Through the linkage between the various components, each group of exhaust components 11 can be slid and unfolded, and each group of electrical installation frames 26 can be separated from the filter barrel 2, so as to prevent dust from overflowing during the cleaning of the outer peripheral side of the filter barrel 2 and causing secondary pollution to the electronic components, thereby improving the cleaning effect of the cabinet 1 and thus improving the heat dissipation effect inside the cabinet 1.

[0044] For example 2, please refer to Figure 1-18The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, the rotating door 14 includes an annular plate 15; a plurality of second mounting openings 16 are evenly provided on the side surface of the annular plate 15; ventilation slots 17 are evenly provided on the side surface of the annular plate 15; a filter screen 75 is provided on the inner wall of the annular plate 15; a mounting plate 18 is fixed on the side surface of the cabinet 1; a magnetic plate 19 is fixed on the surface of the mounting plate 18; a first iron plate 20, a second iron plate 21 and a third iron plate 22 are evenly provided on the side surface of the annular plate 15.

[0045] A gear ring 23 is fixed to the inner side surface of the annular plate 15; an annular groove 24 for rotationally cooperating with the gear ring 23 is provided on the outer side surface of the cabinet 1 near its bottom; fixing rods 25 are evenly fixed to the inner bottom surface of the cabinet 1; an electrical mounting frame 26 is rotatably provided on the fixing rods 25; the electrical mounting frame 26 includes a vertical plate 27; a rotating hole 28 for rotationally cooperating with the fixing rod 25 is provided inside the vertical plate 27; a number of electrical assembly plates 29 are fixed to the opposite sides of the vertical plate 27; a gear ring 30 is fixed to the bottom of the vertical plate 27; the gear ring 30 and the rotating hole 28 are coaxially arranged; each gear ring 30 meshes with the gear ring 23.

[0046] Working principle of the second embodiment:

[0047] The rotating annular plate 15 causes the second iron plate 21 to rotate to above the mounting plate 18 and be adsorbed by the magnetic plate 19. At this time, each group of first mounting ports 13 and each group of second mounting ports 16 are staggered with each other, so that the rotating door 14 is closed. At this time, the vertical plate 27 is perpendicular to the filter barrel 2, so that the dust on the electronic components on the electrical assembly board 29 can be taken away by the flowing air, thereby improving the cleaning effect of the electronic components and, at the same time, improving the heat dissipation effect of the electronic components.

[0048] Rotate the annular plate 15 clockwise so that the first iron plate 20 rotates to the top of the mounting plate 18 and is adsorbed by the magnetic plate 19. At this time, each group of first mounting ports 13 is aligned and overlapped with the corresponding second mounting ports 16, so that the rotating door 14 is opened. During this process, the clockwise rotation of the gear ring 23 drives each group of gear rings 30 to rotate synchronously clockwise until the vertical plate 27 is parallel to the filter barrel 2. At this time, the electronic components on one side of the vertical plate 27 are aligned with the first mounting port 13, which is convenient for the inspection and maintenance of the electronic components on this side.

[0049] The annular plate 15 is rotated counterclockwise, and similarly, the electronic components on the other opposite side of the vertical plate 27 are aligned with the first installation opening 13 , so as to facilitate the inspection and maintenance of the electronic components on the other opposite side of the vertical plate 27 .

[0050] For example 3, please refer to Figure 1-18The third embodiment is improved as follows on the basis of the second embodiment. Specifically, the inner bottom surface of the cabinet 1 is symmetrically provided with slide grooves 31 on both sides of the partition 3; the sliding part includes a slide plate 32; an ear plate 33 that slides with the corresponding slide groove 31 is fixed to the bottom surface of the slide plate 32; a guide hole 34 is provided on the side of the ear plate 33; a guide rod that slides with the guide hole 34 is fixed between the inner walls of the slide groove 31; a reset spring 35 that is sleeved on the guide rod is fixed between the ear plate 33 and the slide groove 31; a rotating plate 36 is rotatably provided on the side of the slide plate 32; an arc spring 74 is fixedly connected between the side of the slide plate 32 and the side of the rotating plate 36.

[0051] A rubber column 37 that plugs into the sealing groove 9 is fixed to the side of the rotating plate 36; a connecting portion 38 is fixed between the ear plates 33 on two adjacent sliding portions; the connecting portion 38 includes a U-shaped plate 39; slots 40 that plug into the ear plates 33 are symmetrically fixed on the surface of the U-shaped plate 39; the ear plates 33 are fixedly installed in the U-shaped plate 39 by fastening bolts.

[0052] An extension rod 41 is fixed to the side of the U-shaped plate 39; a guide ball 42 is fixed to the end of the extension rod 41; a plurality of L-shaped rods 43 are evenly fixed to the bottom surface of the cabinet 1; a fixing ring 44 coaxial with the cabinet 1 is fixed between the ends of each L-shaped rod 43; the guide portion 12 includes a swivel ring 45 rotatably arranged on the inner peripheral side of the fixing ring 44; a plurality of curved guide plates 46 adapted to the guide balls 42 are evenly fixed to the outer peripheral side of the swivel ring 45.

[0053] A retaining ring 47 is coaxially arranged on the inner peripheral side of the swivel 45; a connecting plate 48 is evenly fixed between the retaining ring 47 and the swivel 45; a plurality of screw holes 49 are evenly opened on the surface of the retaining ring 47; a connecting pipe 50 is screwed in the screw hole 49; a dust removal bag 51 is fixed to the bottom end of the connecting pipe 50; an annular gear plate 52 is fixed to the outer peripheral side of the swivel 45; a servo motor 53 is fixedly installed on the surface of the L-shaped rod 43; a gear 54 meshing with the annular gear plate 52 is fixed to the output end of the servo motor 53.

[0054] A number of temperature sensors are evenly installed on the top of the cabinet 1; a controller is installed inside the cabinet 1; the input end of the controller is electrically connected to each temperature sensor, and its output end is electrically connected to the servo motor 53, the exhaust motor 60 and the micro electric push rod 66 respectively.

[0055] Working principle of the third embodiment:

[0056] Each group of temperature sensors is fixedly installed at the top of the cabinet 1 between two adjacent partitions 3. The guide ball 42 is pressed against the outer peripheral side of the rotating ring 45 under the elastic force of the reset spring 35; under the elastic force of the arc spring 74, the rotating plate 36 is driven to press against the guide column 5.

[0057] When the temperature sensor detects that the temperature value at the corresponding position exceeds the set threshold, the retaining ring 47 rotates in contact with the bottom surface of the filter barrel 2, and the controller controls the start-up of the servo motor 53 to drive the gear 54 to rotate a certain angle, thereby driving the annular gear plate 52 and the rotating ring 45 to rotate a certain angle, so that each group of screw holes 49 rotates to be directly below the corresponding ash outlet 10, so that the ash outlet 10 is coaxially connected with the corresponding dust bag 51.

[0058] During this process, the guide ball 42 slides from the outer peripheral side of the curved guide plate 46 to the outer peripheral side of the swivel ring 45, and under the elastic force of the reset spring 35, drives the corresponding sliding part to move toward the direction close to the filter barrel 2. Under the guiding support of the guide column 5, the rotating plate 36 rotates during the movement until the rubber column 37 rotates and engages in the corresponding sealing groove 9, thereby separating each group of electrical mounting frames 26 from the filter barrel 2, preventing dust from overflowing during the cleaning of the filter barrel 2 and causing secondary pollution to the electronic components.

[0059] When the temperature sensor detects that the temperature value at the corresponding position is lower than the set threshold, the controller controls the servo motor 53 to rotate in the opposite direction to drive the gear 54 to rotate in the opposite direction by a certain angle, thereby driving the retaining ring 47 to rotate in the opposite direction by a certain angle to reset, so that the retaining ring 47 blocks each group of ash outlets 10.

[0060] During the rotation of the swivel 45, the corresponding curved guide plate 46 squeezes the corresponding guide ball 42, so that each group of connecting parts 38 drives the sliding part on the corresponding partition assembly 6 to slide along the corresponding slide groove 31 in the direction away from the filter barrel 2, and the corresponding return spring 35 is compressed, so that the rubber column 37 rotates out of the corresponding sealing groove 9, thereby releasing the separation restriction between the electrical mounting frame 26 and the filter barrel 2.

[0061] The above process has a high degree of automation, and cooperates with the exhaust component 11 to achieve separation of air and dust, thereby improving the quality of exhausted air.

[0062] Example 4, please refer to Figure 1-18 The fourth embodiment of the present invention is improved as follows on the basis of the third embodiment. Specifically, an annular groove 55 is provided on the bottom surface of the rotating ring 45; the exhaust assembly 11 includes a hood 56; an annular plate 57 rotatably matched with the annular groove 55 is fixed on the top of the hood 56, and a plurality of positioning plates 58 are evenly fixed on the outer peripheral side thereof; each positioning plate 58 is fixedly mounted on the bottom surface of the L-shaped rod 43 by fastening bolts; a support plate 59 is fixedly mounted on the inner peripheral side of the rotating ring 45; an exhaust motor 60 is fixedly mounted on the bottom surface of the support plate 59; a sleeve 61 is fixedly mounted on the output end of the exhaust motor 60; and exhaust fan blades 62 are fixedly mounted on the peripheral side of the sleeve 61.

[0063] A square column 63 is slidably arranged inside the sleeve 61; a first friction wheel 64 is fixed on the top of the square column 63; a support bar 65 is symmetrically fixed to the inner side surface of the wind hood 56; a micro-electric push rod 66 is fixed on the surface of the support bar 65; a limit ring 67 that rotates with the first friction wheel 64 is fixed between the telescopic ends of the two micro-electric push rods 66; the top of the filter barrel 2 is sealed, and a reciprocating screw rod 68 is rotatably arranged on the top inside; a second friction wheel 69 is fixed to the bottom end of the reciprocating screw rod 68; lifting grooves 70 are evenly arranged on the side surface of the filter barrel 2; the cleaning part 4 includes a sliding sleeve 71 that is compatible with the reciprocating screw rod 68; a lifting plate 72 that slides with the lifting groove 70 is evenly fixed on the outer side surface of the sliding sleeve 71; a dust curtain is connected between the lifting plate 72 and the inner top of the lifting groove 70; an arc plate 73 is fixed to the end of the lifting plate 72; and a number of bristles 7 are evenly arranged on the inner side surface of the arc plate 73.

[0064] Working principle of the fourth embodiment:

[0065] A slider matched with the reciprocating screw 68 is arranged inside the sleeve 71. The reciprocating screw 68 is a form of a three-dimensional cam pair, which is manifested as two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the reciprocating screw 68, the side of the spiral groove pushes the slider placed in the spiral groove to perform axial reciprocating motion.

[0066] When the temperature value detected by the temperature sensor exceeds the set threshold, the controller simultaneously controls the two micro electric push rods 66 to extend synchronously, so that the square column 63 together with the first friction wheel 64 rises and presses the second friction wheel 69, so that the rotation of the sleeve 61 can drive the reciprocating screw rod 68 to rotate synchronously, thereby driving the lifting plate 72 on the cleaning part 4 to reciprocate and lift along the corresponding lifting groove 70 seat, so that the bristles 7 remove the dust on the outer peripheral side of the filter barrel 2, and the dust is collected in the dust bag 51 through the ash outlet 10 with the flowing air flow, completing the self-cleaning of the interior of the cabinet 1.

[0067] When the temperature value detected by the temperature sensor is lower than the set threshold, the controller controls the two micro electric push rods 66 to shrink synchronously, so that the first friction wheel 64 descends and disengages from the second friction wheel 69, preventing the cleaning part 4 from working during the normal ventilation and heat dissipation process of the cabinet 1, causing dust to overflow and causing secondary pollution to the electronic components; when the filter barrel 2 is in the state of normal ventilation and dust filtering, each group of lifting slots 70 is blocked by the dust curtain, so that the filter barrel 2 in this state filters dust as a whole.
