[0002] The power distribution cabinet is a key device for receiving, distributing, controlling and protecting electric energy in the power system. It distributes the electric energy of the main power supply to each branch circuit through internal components, while monitoring the circuit status and providing protection against overload, short circuit, leakage, etc.

[0003] During long-term use of the distribution cabinet, dust will accumulate on the dust screen, which will clog the mesh and reduce the air permeability of the dust screen.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figure 1-3 A dustproof net frame 11 is provided on the side of the distribution cabinet body 1, and the dustproof net 2 is fixedly installed on the dustproof net frame 11 by bolts. A double-sided brush 4 is vertically movably arranged on the dustproof net 2, and a dust storage bin is adapted to be arranged at the bottom of the dustproof net frame 11 corresponding to the double-sided brush 4, and the dust brushed by the double-sided brush 4 can fall directly on the dust storage bin.

[0020] Fixed pulley blocks 12 are provided on both sides of the top of the dustproof net 2 on the distribution cabinet body 1, one end of the traction rope 121 on the fixed pulley block 12 extends into the side cavity 21 and is connected to the side connecting piece 41, and the other end of the traction rope 121 is connected to the water storage bin 5.

[0021] The water storage bin 5 is provided with a slider 52, and the distribution cabinet body 1 is adapted to be provided with a slide groove 13 corresponding to the slider 52. The adaptation setting between the slider 52 and the slide groove 13 can improve the stability of the water storage bin 5 during movement. The top of the distribution cabinet body 1 is adapted to be provided with a water guide groove 14 corresponding to the water storage bin 5, and the setting of the water guide groove 14 can guide rainwater into the water storage bin 5 in rainy weather.

[0022] See also Figure 4 ,10 , vertical side cavities 21 are provided on both sides of the dustproof net 2, and the double-sided brushes 4 are located on both sides of the dustproof net 2 and are fixedly connected by side connectors 41, and the side connectors 41 pass through the side cavities 21. By moving the double-sided brushes 4, impurities accumulated on the dustproof net 2 can be scraped off, and by setting the side connectors 41, the brushes on both sides can be fixedly connected together to form the double-sided brush 4. Moreover, corresponding guide grooves and guide members are adapted between the side cavities 21 and the side connectors 41 to ensure that the side connectors 41 can be located in the side cavities 21 and move vertically stably, thereby improving the stability of the double-sided brushes 4 during movement.

[0023] The outer side of the double-sided brush 4 is provided with a plurality of slots 42 adapted to the elastic clips 23 , and the double-sided brush 4 can be fixed by the mutual engagement between the elastic clips 23 and the slots 42 .

[0024] See also Figure 4-9 , a fixing plate 22 is fixedly arranged on both sides of the top of the dustproof net 2, an elastic clip 23 is installed at the bottom of the fixing plate 22, a bimetallic strip 24 is installed at the bottom of the fixing plate 22 on the outside of the elastic clip 23, and the elastic clip 23 and the bimetallic strip 24 are connected by a connecting rope 231. In this way, when the elastic clip 23 bends due to heat, it can pull the connecting rope 231 outward, so that the elastic clip 23 can be pulled outward by the connecting rope 231 to release the clamping of the elastic clip 23 on the card slot 42. It is worth noting that the bimetallic strip 24 is composed of a combination of low thermal threshold materials (such as aluminum + nickel or copper + Invar alloy, etc.), and its surface is coated with a high heat absorption coating such as black chrome or graphene coating. This allows the bimetallic strip 24 to bend after being heated by the light focused by the convex lens 32. This is a prior art, so it is not elaborated.

[0025] A plurality of support seats 3 are fixedly arranged on the top of the dustproof net 2, and a rotating shaft 31 is rotatably arranged on the support seat 3 through a bearing. The rotating shaft 31 is mounted on the bearing by an interference fit, which makes the rotating shaft 31 only rotate on the support seat 3 and cannot move.

[0026] A convex lens 32 is adapted to be arranged on the rotating shaft 31 corresponding to the bimetallic strip 24 , and the convex lens 32 can focus sunlight onto the bimetallic strip 24 , so that the temperature of the bimetallic strip 24 can be increased by light to achieve the bending of the bimetallic strip 24 .

[0027] A shield 25 is fixedly provided on the fixed plate 22 on the outer side of the bimetallic strip 24. The shield 25 can prevent sunlight from being focused on the bimetallic strip 24 through the convex lens 32 for a long time, so as to prevent the bimetallic strip 24 from experiencing material fatigue due to long-term irradiation and temperature rise.

[0028] The ends of the rotating shaft 31 are fixed with counterweight magnets 34 through connecting frames 33 . The counterweight magnets 34 are located on the rotating shaft 31 at different angles than the convex lens 32 , and the weight of the counterweight magnets 34 is greater than that of the convex lens 32 .

[0029] This makes it possible for the counterweight magnet 34 to attract the auxiliary magnetic column 516 and the magnetic plate 517 when the water storage tank 5 is located on one side of the counterweight magnet 34, so that the counterweight magnet 34 rotates toward the auxiliary magnetic column 516 and the magnetic plate 517, thereby driving the entire rotating shaft 31 to rotate, so that the convex lens 32 rotates synchronously with the rotating shaft 31. At this time, the convex lens 32 is in a vertical state, and the light focused in the convex lens 32 can only be irradiated on the shielding plate 25, and the shielding plate 25 is a high reflectivity heat-resistant material in the prior art.

[0030] When the counterweight magnet 34 is not attracted to the secondary magnetic column 516 and the magnetic plate 517, the counterweight magnet 34 can sag by its own gravity, thereby driving the rotating shaft 31 to rotate. During the rotation of the rotating shaft 31, the convex lens 32 can be driven to rotate synchronously, so that the convex lens 32 faces the bimetallic strip 24, and the convex lens 32 can focus the sunlight onto the bimetallic strip 24.

[0031] See also Figure 11-14 , 15-16, a movable bottom plate 51 is provided at the bottom of the water storage bin 5, and the bottom of the water storage bin 5 can be opened by moving the movable bottom plate 51, so that the water in the water storage bin 5 can be released. A plurality of spring cavities 511 are provided on the movable bottom plate 51, and springs 512 are provided outwardly in the spring cavities 511, and the other ends of the springs 512 are connected to the inner wall of the water storage bin 5. This allows the springs 512 to be compressed when the movable bottom plate 51 is extended outward by the magnetic attraction, and when the magnetic attraction disappears, the movable bottom plate 51 can be automatically reset to the water storage bin 5 by the elastic force of the springs 512.

[0032] Magnetic plates 517 are provided on both sides of the spring cavity 511 on the movable bottom plate 51, and auxiliary plate cavities 513 are provided inwardly on the outer sides of the magnetic plates 517 on the movable bottom plate 51, and multiple elastic columns 514 are provided outwardly in the auxiliary plate cavities 513, and the other ends of the elastic columns 514 are connected to the auxiliary plates 515, and the ends of the auxiliary plates 515 on both sides are connected to the auxiliary magnetic columns 516. Through the provision of the elastic columns 514, the auxiliary plates 515 can be pushed out of the auxiliary plate cavity 513, so that the auxiliary magnetic columns 516 can be pushed out. When the auxiliary magnetic columns 516 move inwardly due to external force, the auxiliary plates 515 can be retracted into the auxiliary plate cavity 513, and the elastic columns 514 are compressed. When the external force disappears, the auxiliary plates 515 can be pushed out of the auxiliary plate cavity 513 by the elastic force of the elastic columns 514, so that the auxiliary magnetic columns 516 can be pushed out again. It is worth noting that the elastic column 514 is a prior art and thus will not be described in detail.

[0033] Among them, the water storage bin 5 and the sub-plate cavity 513 are equipped with guiding mechanisms corresponding to the movable bottom plate 51 and the sub-plate 515, which can not only ensure the stability of the movable bottom plate 51 and the sub-plate 515 during movement, but also prevent the movable bottom plate 51 and the sub-plate 515 from falling off.

[0034] See also Fig.12 , 14 -15, 19, an inclined movable plate 53 is provided above the movable bottom plate 51 in the water storage bin 5, and a plurality of side magnetic columns 531 are fixedly provided on both sides of the inclined movable plate 53, and an inclined groove 532 is adapted to be provided on the inner wall of the water storage bin 5 corresponding to the side magnetic columns 531, and side grooves 533 which are not connected to each other are adapted to be provided on the outer wall of the water storage bin 5 corresponding to the inclined grooves 532.

[0035] When the inclined movable plate 53 is located at the bottom, even if the movable bottom plate 51 moves outward, water can still be stored in the water storage bin 5 through the inclined movable plate 53. When the inclined movable plate 53 moves upward and the movable bottom plate 51 moves outward, drainage in the water storage bin 5 can be achieved.

[0036] See also Figure 3 , 18 , the power distribution cabinet body 1 is fixedly provided with a fixing frame 6 on both sides of the bottom of the dust screen 2, and the fixing frame 6 is adapted to the water storage bin 5. A plurality of fixed magnets 61 are provided on the fixing frame 6, and the fixed magnets 61 are adapted to attract each other with the secondary magnetic column 516 and the magnetic plate 517. A guide slope 62 is fixedly provided on the top of the fixing frame 6, and through the setting of the guide slope 62, the secondary plate 515 can be pushed into the secondary plate cavity 513 when the water storage bin 5 moves downward.

[0037] Side magnets 63 are fixedly arranged on both sides of the fixing frame 6 through side plates. When the water storage tank 5 moves to the fixing frame 6, the side magnets 63 are all adapted to be located in the side grooves 533. In this way, the side magnetic pillars 531 can be adsorbed by the side magnets 63, so that the side magnetic pillars 531 in the inclined grooves 532 can be adsorbed upward, thereby driving the entire inclined movable plate 53 to move upward.

[0038] In this embodiment, the dustproof net 2 is fixedly installed on the dustproof net outer frame 11 by bolts. The dustproof net 2 is a primary filter screen, which is only used to intercept large particles of impurities in the air. An active dust removal and dehumidification device is also provided inside the power distribution cabinet body 1. The dust removal device uses negative pressure technology to absorb dust in the cabinet, and the dehumidification device uses semiconductor condensation technology to absorb humid air and condense it into water for discharge, so as to achieve the final dust removal and dehumidification of the power distribution cabinet. It is worth noting that active dust removal and dehumidification devices are all existing technologies, so they will not be elaborated.

[0039] Furthermore, the power distribution cabinet body 1 in this embodiment is installed outdoors, and the dust screen 2 is cleaned by the change of sunny and rainy weather outdoors. This method of cleaning the dust screen 2 does not require labor costs, electricity, and control systems, and only relies on outdoor weather changes. The dust screen 2 can be automatically cleaned when the weather changes, and there is no need for manual regular cleaning of the dust screen 2.

[0040] On rainy days, rainwater is directed into the water storage bin 5 through the water guide groove 14 on the power distribution cabinet body 1, so that water can be stored in the water storage bin 5 to increase the gravity of the water storage bin 5 on both sides. At this time, the water storage bin 5 can automatically descend, and during the descent of the water storage bin 5, it can pull the traction rope 121, so that the double-sided brush 4 at the other end of the traction rope 121 can be pulled upward through the fixed pulley block 12, so that the height of the double-sided brush 4 can be increased by the descent of the water storage bin 5.

[0041] When the water storage tank 5 is completely lowered to the fixed frame 6, the fixed magnet 61 on the fixed frame 6 can adsorb the auxiliary magnetic column 516 and the magnetic plate 517 outward, so that the magnetic plate 517 can drive the movable bottom plate 51 to move outward, and the movable bottom plate 51 is opened. At this time, the side magnet 63 is adapted to be located in the side groove 533, so that the side magnetic column 531 can be adsorbed by the side magnet 63, so that the side magnetic column 531 can be driven to move obliquely upward in the inclined groove 532 by magnetic attraction, so as to drive the inclined movable plate 53 to move obliquely upward synchronously. At this time, the drainage of the water storage tank 5 can be achieved.

[0042] When the water storage bin 5 is completely lowered to the fixing frame 6, the double-sided brush 4 is adapted to move to the top of the dustproof net 2, and the elastic clamp 23 can be automatically clamped in the clamping groove 42. Thus, the double-sided brush 4 can be fixed by the mutual clamping between the elastic clamp 23 and the clamping groove 42 to prevent the double-sided brush 4 from falling, and the water storage bin 5 is firmly located on the fixing frame 6 by its own gravity. In this way, the dustproof net 2 can be cleaned when the double-sided brush 4 moves upward, and the double-sided brush 4 can also store energy.

[0043] On sunny days, sunlight is focused by the convex lens 32 and irradiated onto the bimetallic strip 24, thereby heating the bimetallic strip 24 so that the bimetallic strip 24 is bent by the heat. Thus, the connecting rope 231 can be pulled by the bending of the bimetallic strip 24, so that the elastic clamp 23 can be pulled by the connecting rope 231, thereby releasing the clamping of the elastic clamp 23 on the clamping groove 42. At this time, the double-sided brush 4 can automatically drop by gravity, so that the dustproof net 2 can be cleaned again when the double-sided brush 4 drops. And through the setting of the fixed pulley block 12 and the traction rope 121, the water storage bins 5 on both sides can be automatically pulled upwards during the falling process of the double-sided brush 4 to achieve the reset of the device, so that the device can continue to repeat the above operation on the next rainy day.

[0044] Furthermore, on a sunny day, when the double-sided brush 4 falls, the water storage bin 5 moves upwards by the traction of the traction rope 121. In the process of the water storage bin 5 moving upwards away from the fixed frame 6, the side magnet 63 no longer adsorbs the side magnetic column 531, and the inclined movable plate 53 can fall by its own gravity. The fixed magnet 61 no longer adsorbs the magnetic plate 517, and the movable bottom plate 51 can automatically reset to the water storage bin 5 by the elastic force of the spring 512. The fixed frame 6 no longer clamps the auxiliary magnetic column 516, and the auxiliary plate 515 and the auxiliary magnetic column 516 can automatically extend by the elastic force of the elastic column 514.

[0045] As the water storage tank 5 moves upward, when the secondary magnetic column 516 approaches the counterweight magnet 34 on the rotating shaft 31, the counterweight magnet 34 can be attracted by the secondary magnetic column 516 to drive the counterweight magnet 34 to rotate slightly, thereby driving the rotating shaft 31 and the convex lens 32 to rotate through the rotation of the counterweight magnet 34. As the water storage tank 5 continues to move upward, the counterweight magnet 34 can be attracted by the secondary magnetic column 516 to rotate and approach the magnetic plate 517.

[0046] When the counterweight magnet 34 and the magnetic plate 517 are close to each other, the magnetic plate 517 can be attracted by the counterweight magnet 34 and drive the movable bottom plate 51 to move outside the water storage tank 5. During the adsorption process of the magnetic plate 517 and the counterweight magnet 34, they continuously squeeze the auxiliary magnetic column 516, so that the auxiliary plate 515 can be continuously squeezed into the auxiliary plate cavity 513, and the elastic column 514 is compressed. Finally, when the water storage tank 5 moves to the top, the auxiliary plate 515 is completely squeezed into the auxiliary plate cavity 513, the auxiliary magnetic column 516 contacts the magnetic plate 517, and the counterweight magnet 34 is attracted and contacted with the auxiliary magnetic column 516 and the magnetic plate 517 by magnetic attraction.

[0047] In this way, by adsorbing the counterweight magnet 34, the counterweight magnet 34, the rotating shaft 31 and the convex lens 32 can be driven to rotate, so that the convex lens 32 can be rotated to a vertical direction, so that the sunlight focused in the convex lens 32 can no longer irradiate the bimetallic strip 24, but irradiate the shielding plate 25 instead, so as to avoid the bimetallic strip 24 from material fatigue due to long-term continuous irradiation and temperature rise.

[0048] The reason for setting the auxiliary magnetic column 516 in this structure is that: when the water storage tank 5 moves upward, the magnetic plate 517 is located in the water storage tank 5, which makes the distance between the magnetic plate 517 and the counterweight magnet 34 relatively far, so they cannot be adsorbed together. Therefore, by setting the auxiliary plate 515 and the auxiliary magnetic column 516, when the water storage tank 5 moves upward, the counterweight magnet 34 can be adsorbed for a distance, so that the counterweight magnet 34 is close to the magnetic plate 517, so that when the water storage tank 5 moves to the top, the magnetic plate 517 can be adapted to be adsorbed together with the counterweight magnet 34.

[0049] Furthermore, when the water storage tank 5 is storing water on rainy days, the movable bottom plate 51 is located outside due to the adsorption between the magnetic plate 517 and the counterweight magnet 34. However, since the movable bottom plate 51 does not move farther than the inclined movable plate 53 when moving outward, rainwater entering the water storage tank 5 can be stored on the movable bottom plate 51 on one side of the inclined movable plate 53, and the inclined movable plate 53 can replace the side wall of the water storage tank 5 to store water.

[0050] The weight of this rainwater and the impact force of the falling rainwater can drive the water storage bin 5 to move downward. When the water storage bin 5 moves to a certain height, the magnetic plate 517 releases the adsorption with the counterweight magnet 34. At this time, the movable bottom plate 51 can be automatically reset to the water storage bin 5 by the elastic force of the spring 512, so that the water storage bin 5 can fully accumulate rainwater, thereby driving the water storage bin 5 to move downward quickly.

[0051] When the water storage tank 5 is about to contact the fixing frame 6, the auxiliary magnetic column 516 located on the outside first contacts the guide slope 62, so that the auxiliary magnetic column 516 can be pushed to the auxiliary plate cavity 513 through the guide slope 62, so that the auxiliary plate 515 is squeezed into the auxiliary plate cavity 513, and the elastic column 514 is compressed. When the water storage tank 5 completely falls on the fixing frame 6, the magnetic plate 517 can be adsorbed outwards through the fixed magnet 61 to drive the movable bottom plate 51 to move toward the fixed magnet 61. And the side magnetic column 531 can be adsorbed through the side magnet 63, so that the inclined movable plate 53 moves obliquely upward, and the water storage tank 5 can be drained at this time.

[0052] When the water storage tank 5 moves downward, the counterweight magnet 34 can automatically droop due to gravity because the magnetic plate 517 is no longer attracted to the counterweight magnet 34. The drooping of the counterweight magnet 34 can drive the rotating shaft 31 and the convex lens 32 to rotate, so that the convex lens 32 can be rotated toward the bimetallic strip 24 again, so that the convex lens 32 can focus sunlight onto the bimetallic strip 24 on the next sunny day.

[0053] Furthermore, the gravity of the double-sided brush 4 is greater than the sum of the gravity of the water storage bins 5 on both sides; the sum of the gravity of the rainwater stored in the water storage bins 5 on both sides plus the inclined movable plates 53 is slightly greater than the gravity of the double-sided brush 4; the sum of the gravity of the water storage bins 5 on both sides plus the fully accumulated rainwater is completely greater than the gravity of the double-sided brush 4.

[0054] Furthermore, the counterweight magnet 34, the fixed magnet 61 and the side magnet 63 are all magnets that can provide magnetic force and adsorb metal, and the secondary magnetic column 516, the magnetic plate 517 and the side magnetic column 531 are all magnetic materials that can be adsorbed. Therefore, the counterweight magnet 34 or the fixed magnet 61 can adsorb the secondary magnetic column 516 and the magnetic plate 517, and the side magnetic column 531 can be adsorbed by the side magnet 63, while the secondary magnetic column 516, the magnetic plate 517 and the side magnetic column 531 cannot adsorb each other.

[0055] In the present invention, the double-sided brush 4 can be driven to move on the dustproof net 2 through the changes of sunny and rainy days, so that the dust accumulated on the dustproof net 2 can be brushed off by the double-sided brush 4, so as to avoid the dust accumulated on the dustproof net 2 affecting the normal heat dissipation performance and dehumidification performance of the distribution cabinet body 1. This structure only relies on weather changes to achieve automatic cleaning of the dustproof net 2, and no manual cleaning is required.
