Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and particularly to a distribution cabinet with dehumidification and dust removal functions. Background Art

[0002] A distribution cabinet is a key device in the power system for receiving, distributing, controlling, and protecting electric energy. 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 the long-term use of the distribution cabinet, dust will accumulate on its dust-proof net. The accumulation of dust will block the mesh holes and reduce the air permeability of the dust-proof net. This will affect the air circulation inside the distribution cabinet, not only affecting the heat dissipation performance of the distribution cabinet, but also making it difficult for the humid air inside the distribution cabinet to be discharged, resulting in an increase in internal humidity. Therefore, it is necessary to clean the dust-proof net regularly. However, the dust-proof nets on traditional distribution cabinets are often cleaned manually, which not only has poor cleaning efficiency but also high labor costs. Summary of the Invention

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0042] Refer to Figures 1-3 , a dust-proof net outer frame 11 is provided on the side of the main body 1 of the power distribution cabinet, the dust-proof net 2 is fixedly installed on the dust-proof net outer frame 11 through bolts, a double-sided brush 4 is vertically movably arranged on the dust-proof net 2, and a dust storage bin is correspondingly arranged at the bottom of the dust-proof net outer frame 11 for the double-sided brush 4, and the dust brushed off by the double-sided brush 4 can directly fall on the dust storage bin.

[0043] On both sides of the power distribution cabinet body 1 above the top of the dust-proof net 2, fixed pulley groups 12 are provided. One end of the traction rope 121 on the fixed pulley group 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.

[0044] Sliders 52 are provided on the water storage bin 5, and sliding grooves 13 are correspondingly and adaptively provided on the power distribution cabinet body 1 for the sliders 52. Through the adaptive setting between the sliders 52 and the sliding grooves 13, the stability of the water storage bin 5 during movement can be improved. Guide water grooves 14 are correspondingly and adaptively provided on the top of the power distribution cabinet body 1 for the water storage bin 5. Through the setting of the guide water grooves 14, rainwater can be diverted into the water storage bin 5 during rainy weather.

[0045] Refer to Figure 4 、 10 On both sides of the dust-proof net 2, vertical side cavities 21 are provided. The double-sided brush 4 is located on both sides of the dust-proof net 2 and is fixedly connected by the side connecting piece 41, and the side connecting piece 41 passes through the side cavity 21. Through the movement of the double-sided brush 4, the impurities accumulated on the dust-proof net 2 can be scraped off. Through the setting of the side connecting piece 41, not only can the brushes on both sides be fixedly connected together to form the double-sided brush 4. Moreover, corresponding guide grooves and guide pieces are adaptively provided between the side cavity 21 and the side connecting piece 41 to ensure that the side connecting piece 41 can move vertically stably within the side cavity 21, thereby improving the stability of the double-sided brush 4 during movement.

[0046] A plurality of card slots 42 adapted to the elastic clamping members 23 are provided on the outer side of the double-sided brush 4. Through the mutual clamping between the elastic clamping members 23 and the card slots 42, the fixation of the double-sided brush 4 can be realized.

[0047] Refer to Figures 4-9 On both sides of the top of the dust-proof net 2, fixing plates 22 are fixedly provided. Elastic clamping members 23 are installed at the bottoms of the fixing plates 22. Bimetallic sheets 24 are installed on the outside of the elastic clamping members 23 at the bottoms of the fixing plates 22, and the elastic clamping members 23 and the bimetallic sheets 24 are connected by connecting ropes 231. In this way, when the elastic clamping member 23 bends due to heat, it can pull the connecting rope 231 outwards, and thus the elastic clamping member 23 can be pulled outwards through the connecting rope 231 to release the clamping of the elastic clamping member 23 on the card slot 42. It should be noted that the bimetallic sheet 24 is composed of a low heat threshold material combination (such as aluminum + nickel or copper + invar alloy, etc.), and its surface is coated with a high heat absorption coating such as black chromium or graphene coating. This enables the bimetallic sheet 24 to bend after being irradiated by the light focused by the convex lens 32 and heated up. This is the prior art, so it will not be elaborated here.

[0048] A plurality of support seats 3 are fixedly arranged at the top of the dust-proof net 2, and a rotating shaft 31 is rotatably arranged on the support seat 3 through a bearing. The rotating shaft 31 is installed on the bearing by interference fit, which enables the rotating shaft 31 to only rotate on the support seat 3 and cannot move.

[0049] A convex lens 32 is adaptively arranged on the rotating shaft 31 corresponding to the bimetallic strip 24. The convex lens 32 can focus sunlight on the bimetallic strip 24, so that the temperature of the bimetallic strip 24 can be increased by light irradiation to realize the bending of the bimetallic strip 24.

[0050] Shields 25 are fixedly arranged on the fixing plate 22 on the outer sides of the bimetallic strips 24. Through the arrangement of the shields 25, it is possible to prevent sunlight from being focused on the bimetallic strips 24 through the convex lens 32 for a long time, so as to avoid the phenomenon of material fatigue of the bimetallic strips 24 due to long-term irradiation and temperature rise.

[0051] Counterweight magnets 34 are fixedly arranged at the ends of the rotating shaft 31 through connecting frames 33. The angles of the counterweight magnets 34 on the rotating shaft 31 are different from those of the convex lens 32, and the weight of the counterweight magnets 34 is greater than the weight of the convex lens 32.

[0052] This makes it so that when the water storage bin 5 is on one side of the counterweight magnet 34, the counterweight magnet 34 will adsorb to the secondary magnetic column 516 and the magnetic plate 517, so that the counterweight magnet 34 rotates towards the secondary magnetic column 516 and the magnetic plate 517, thereby driving the entire rotating shaft 31 to rotate, causing the convex lens 32 to rotate synchronously with the rotating shaft 31. At this time, the convex lens 32 is in a vertical state, and the focused light in the convex lens 32 can only irradiate on the shield 25, and the shield 25 is a high-reflectivity heat-resistant material in the prior art.

[0053] When the counterweight magnet 34 does not adsorb to the secondary magnetic column 516 and the magnetic plate 517, the counterweight magnet 34 can droop due to 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. At this time, the sun's rays can be focused on the bimetallic strip 24 through the convex lens 32.

[0054] Refer to Figures 11-14, 15 - 16, a movable bottom plate 51 is provided at the bottom of the water storage bin 5. By moving the movable bottom plate 51, the bottom of the water storage bin 5 can be opened, and thus the water in the water storage bin 5 can be discharged. A plurality of spring cavities 511 are formed on the movable bottom plate 51, springs 512 are arranged outward 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 enables the springs 512 to be compressed when the movable bottom plate 51 extends outward by magnetic attraction, and when the magnetic attraction disappears, the movable bottom plate 51 can automatically reset into the water storage bin 5 by the elastic force of the springs 512.

[0055] Magnetic plates 517 are arranged on both sides of the spring cavities 511 on the movable bottom plate 51. Sub - plate cavities 513 are formed inward on the movable bottom plate 51 outside the magnetic plates 517. A plurality of elastic columns 514 are arranged outward in the sub - plate cavities 513, the other ends of the elastic columns 514 are connected to the sub - plates 515, and the ends of the two - side sub - plates 515 are connected to the sub - magnetic columns 516. Through the arrangement of the elastic columns 514, the sub - plates 515 can be pushed out of the sub - plate cavities 513, and thus the sub - magnetic columns 516 can be pushed outwards. When the sub - magnetic columns 516 move inwards due to external force, the sub - plates 515 can be retracted into the sub - plate cavities 513, and the elastic columns 514 are compressed. When the external force disappears, the elastic force of the elastic columns 514 can push the sub - plates 515 out of the sub - plate cavities 513, and thus the sub - magnetic columns 516 can be pushed out again. It should be noted that the elastic columns 514 are prior art, so no more details will be given.

[0056] Among them, guiding mechanisms are correspondingly arranged in the water storage bin 5 and the sub - plate cavities 513 for the movable bottom plate 51 and the sub - plates 515 respectively. This can not only ensure the stability of the movable bottom plate 51 and the sub - plates 515 during movement, but also prevent the movable bottom plate 51 and the sub - plates 515 from falling off.

[0057] Refer to Figure 12 , 14 - 15, 19, inclined movable plates 53 are arranged above the movable bottom plate 51 in the water storage bin 5. A plurality of side magnetic columns 531 are fixedly arranged on both sides of the inclined movable plates 53. Inclined grooves 532 are correspondingly formed on the inner wall of the water storage bin 5 for the side magnetic columns 531, and non - communicating side grooves 533 are correspondingly formed on the outer wall of the water storage bin 5 for the inclined grooves 532.

[0058] When the inclined movable plates 53 are at the lower position, even if the movable bottom plate 51 moves outwards, the water storage in the water storage bin 5 can still be realized through the inclined movable plates 53. When the inclined movable plates 53 move upwards and the movable bottom plate 51 moves outwards, the drainage of the water storage bin 5 can be realized.

[0059] Refer to Figure 3 , 18, on both sides of the power distribution cabinet body 1 at the bottom of the dust-proof net 2, fixing frames 6 are fixedly arranged, and the fixing frames 6 are adapted to the water storage bin 5. A plurality of fixing magnets 61 are arranged on the fixing frames 6, and the fixing magnets 61 are all adapted to attract the secondary magnetic columns 516 and the magnetic plates 517. Guide slopes 62 are fixedly arranged at the tops of the fixing frames 6. Through the arrangement of the guide slopes 62, when the water storage bin 5 moves downward, the secondary plate 515 can be pushed into the secondary plate cavity 513.

[0060] On both sides of the fixing frame 6, side magnets 63 are fixedly arranged through side plates. When the water storage bin 5 moves to the position of the fixing frame 6, the side magnets 63 are all adapted to be located in the side grooves 533. In this way, the side magnets 63 can be used to adsorb the side magnetic columns 531, so that the side magnetic columns 531 in the inclined grooves 532 can be adsorbed upward, thereby driving the entire inclined movable plate 53 to move upward.

[0061] In this embodiment, the dust-proof net 2 is fixedly installed on the dust-proof net outer frame 11 through bolts. The dust-proof net 2 is a primary filter screen, which is only used to intercept large particle impurities in the air. An active dust removal and dehumidification device is also arranged inside the power distribution cabinet body 1. The dust removal device uses negative pressure technology to suck out the dust in the cabinet, and the dehumidification device uses semiconductor condensation technology to suck in the wet air and condense it into water and discharge it to achieve the final dust removal and dehumidification of the power distribution cabinet. It should be noted that the active dust removal and dehumidification devices are all prior arts, so no more details will be given.

[0062] Furthermore, the power distribution cabinet body 1 in this embodiment is installed outdoors. Through the changes in sunny and rainy weather outdoors, the dust-proof net 2 can be cleaned. This method of cleaning the dust-proof net 2 does not require labor costs, nor does it require electricity and control systems. It only depends on the weather changes outdoors and can automatically clean the dust-proof net 2 when the weather changes, without the need for manual regular cleaning of the dust-proof net 2.

[0063] During rainy days, rainwater is diverted into the water storage bin 5 through the water diversion trough 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 two water storage bins 5 on both sides. At this time, the water storage bin 5 can automatically descend. 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 group 12, and thus the height of the double-sided brush 4 can be increased by the descent of the water storage bin 5.

[0064] When the water storage bin 5 completely descends to the fixing frame 6, the fixing magnet 61 on the fixing frame 6 can adsorb the auxiliary magnetic column 516 and the magnetic plate 517 outwards, so that the movable bottom plate can be driven to move outwards by the magnetic plate 517, and at this time the movable bottom plate 51 is opened. And at this time, the side magnet 63 is properly located in the side groove 533, so that the side magnetic column 531 can be adsorbed by the side magnet 63, and then the side magnetic column 531 can be driven to move obliquely upwards in the inclined groove 532 by the magnetic attraction force, so as to drive the inclined movable plate 53 to move obliquely upwards synchronously. At this time, the drainage of the water storage bin 5 can be realized.

[0065] And when the water storage bin 5 completely descends to the fixing frame 6, the double-sided brush 4 is properly moved to the top of the dust-proof net 2, and at this time the elastic clamping member 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 clamping member 23 and the clamping groove 42 to prevent the double-sided brush 4 from falling, and at this time the water storage bin 5 is stably located on the fixing frame 6 by its own gravity. In this way, not only can the dust-proof net 2 be cleaned when the double-sided brush 4 moves upwards, but also the energy storage of the double-sided brush 4 can be realized.

[0066] On a sunny day, the sunlight is focused by the convex lens 32 and then irradiates on the bimetallic strip 24, so as to realize the heating of the bimetallic strip 24, so that the bimetallic strip 24 is heated and bent. Thus, the connecting rope 231 can be pulled by the bending of the bimetallic strip 24, and in this way, the elastic clamping member 23 can be pulled by the connecting rope 231, so that the clamping of the elastic clamping member 23 to the clamping groove 42 can be released. At this time, the double-sided brush 4 can automatically descend by gravity, so that the dust-proof net 2 can be cleaned again when the double-sided brush 4 descends. And through the setting of the fixed pulley group 12 and the traction rope 121, during the falling process of the double-sided brush 4, the water storage bins 5 on both sides can be automatically pulled upwards to realize the reset of the device, so that the device can repeat the above operations on the next rainy day.

[0067] Furthermore, on a sunny day when the double-sided brush 4 is falling, the water storage bin 5 is pulled upwards by the traction rope 121. During the process of the water storage bin 5 moving upwards and leaving the fixing frame 6, the side magnet 63 no longer adsorbs the side magnetic column 531, and at this time the inclined movable plate 53 can fall by its own gravity. The fixing magnet 61 no longer adsorbs the magnetic plate 517, and at this time the movable bottom plate 51 can be automatically reset into the water storage bin 5 by the elastic force of the spring 512. The fixing 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.

[0068] As the water storage bin 5 moves upward, when the auxiliary magnetic column 516 approaches the counterweight magnet 34 on the rotating shaft 31, the counterweight magnet 34 can be adsorbed by the auxiliary magnetic column 516 to drive the counterweight magnet 34 to rotate slightly, so that the rotating shaft 31 and the convex lens 32 can be driven to rotate by the rotation of the counterweight magnet 34. As the water storage bin 5 continues to move upward, the counterweight magnet 34 can be attracted by the auxiliary magnetic column 516 to continuously rotate and approach the magnetic plate 517.

[0069] When the counterweight magnet 34 approaches the magnetic plate 517, the magnetic plate 517 can be adsorbed by the counterweight magnet 34 and drive the movable bottom plate 51 to move outside the water storage bin 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 bin 5 moves to the topmost position, 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 adsorbed and contacted with the auxiliary magnetic column 516 and the magnetic plate 517 through magnetic attraction.

[0070] 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 the vertical direction. So that the sunlight focused in the convex lens 32 can no longer shine on the bimetallic strip 24, but instead shines on the shutter 25, to avoid the phenomenon of material fatigue of the bimetallic strip 24 due to continuous heating by long-term irradiation.

[0071] The reason for setting the auxiliary magnetic column 516 in this structure is that when the water storage bin 5 moves upward, the magnetic plate 517 is located inside the water storage bin 5, which makes the distance between the magnetic plate 517 and the counterweight magnet 34 relatively far, so they cannot be adsorbed together. Therefore, through the setting of the auxiliary plate 515 and the auxiliary magnetic column 516, the counterweight magnet 34 can be adsorbed for a certain distance when the water storage bin 5 moves upward, so that the counterweight magnet 34 approaches the magnetic plate 517, so that when the water storage bin 5 moves to the topmost position, the magnetic plate 517 can be properly adsorbed with the counterweight magnet 34.

[0072] Furthermore, on a rainy day when the water storage bin 5 is storing water, due to the adsorption between the magnetic plate 517 and the counterweight magnet 34, the movable bottom plate 51 is on the outside. However, since the farthest moving distance of the movable bottom plate 51 when it moves outward does not exceed the inclined movable plate 53, the rainwater entering the water storage bin 5 at this time can accumulate on the movable bottom plate 51 on one side of the inclined movable plate 53, and at this time the inclined movable plate 53 can replace the side wall of the water storage bin 5 to achieve water storage.

[0073] The weight of this part of the rainwater and the impact force of the falling rain 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 automatically reset into the water storage bin 5 through the elastic force of the spring 512. In this way, the water storage bin 5 can fully accumulate rainwater, and thus can drive the water storage bin 5 to move downward quickly.

[0074] When the water storage bin 5 is about to contact the fixed frame 6, the auxiliary magnetic column 516 on the outside first contacts the guiding slope 62. Thus, the auxiliary magnetic column 516 can be pushed towards the auxiliary plate cavity 513 through the guiding 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 bin 5 completely lands on the fixed frame 6, the magnetic plate 517 can be adsorbed outward by the fixed magnet 61 to drive the movable bottom plate 51 to move towards the fixed magnet 61. And the side magnet 63 can adsorb the side magnetic column 531 to make the inclined movable plate 53 move obliquely upward. At this time, the drainage of the water storage bin 5 can be realized.

[0075] And when the water storage bin 5 moves downward, since the magnetic plate 517 is no longer adsorbed with the counterweight magnet 34, the counterweight magnet 34 can automatically droop due to gravity. Thus, the rotation shaft 31 and the convex lens 32 can be driven to rotate by the drooping of the counterweight magnet 34. In this way, the convex lens 32 can be rotated towards the bimetallic strip 24 again, so that the convex lens 32 can focus sunlight on the bimetallic strip 24 on the next sunny day.

[0076] Furthermore, the gravity of the double-sided brush 4 is greater than the sum of the gravities of the two side water storage bins 5; the sum of the gravities of the two side water storage bins 5 plus the rainwater accumulated by the inclined movable plate 53 is slightly greater than the gravity of the double-sided brush 4; the sum of the gravities of the two side water storage bins 5 plus the rainwater fully accumulated is completely greater than the gravity of the double-sided brush 4.

[0077] Furthermore, the counterweight magnet 34, the fixed magnet 61 and the side magnet 63 are all magnets that can provide magnetic force and adsorb metals, and the auxiliary magnetic column 516, the magnetic plate 517 and the side magnetic column 531 are all magnetic materials that can be adsorbed. Therefore, the auxiliary magnetic column 516 and the magnetic plate 517 can be adsorbed by the counterweight magnet 34 or the fixed magnet 61, and the side magnetic column 531 can be adsorbed by the side magnet 63, while the auxiliary magnetic column 516, the magnetic plate 517 and the side magnetic column 531 cannot adsorb each other.

[0078] In the present invention, with the changes between sunny days and rainy days, the double-sided brush 4 can be driven to move on the dust-proof net 2, so that the dust accumulated on the dust-proof net 2 can be brushed off by the double-sided brush 4, thereby avoiding the influence of the dust accumulated on the dust-proof net 2 on the normal heat dissipation performance and dehumidification performance of the power distribution cabinet body 1. This structure realizes the automatic dust cleaning of the dust-proof net 2 only relying on weather changes without manual cleaning.

[0079] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
