An outdoor distribution box

Abstract

The present invention relates to the technical field of distribution boxes, and specifically relates to an outdoor distribution box, which includes a distribution box main body. A fixed frame is fixed to the inner wall of the distribution box main body. A dust-proof filter screen is arranged on the inner wall of the fixed frame. A third guide rod is fixed to the inner wall of the fixed frame. A third slider is slidably arranged on the outer wall of the third guide rod, and a third return spring is sleeved on the third guide rod. In this outdoor distribution box, the dust-proof filter screen is urged to be in a state of inclining towards the outside of the distribution box main body. Since the entire dust-proof filter screen is inclined, the dust blocked in the gaps of the dust-proof filter screen will not fall into the distribution box main body during the cleaning process, but will only fall along the inclined corner onto the inclined surface opened on the air permeable groove. During the rotation of the dust-proof filter screen, the dust-proof filter screen can always play a dust-proof role on the contour in the air permeable groove during the rotation process, preventing dust from entering due to the appearance of gaps during the rotation process.

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and particularly to an outdoor distribution box. Background Art

[0002] An outdoor distribution box is an electrical equipment, which has the characteristics of small volume, simple installation, special technical performance, fixed position, unique configuration function, not restricted by the site, widespread application, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect, so it is applied to various construction sites.

[0003] At present, during the use of the existing outdoor distribution boxes on the market, since the distribution box itself will continuously generate a certain amount of heat during use, the distribution box is usually set with hollowed-out settings on at least two sides or more. However, the simple hollowed-out setting is likely to allow external dust to enter the interior of the distribution box, resulting in the generation of static electricity when the dust amount in the distribution box reaches a certain limit. Because the existing distribution boxes usually have slots on the side walls of the distribution box on two sides or more, and dust-proof nets for dust prevention are arranged in the slots. After these dust-proof nets are used for a period of time, a thick layer of dust will be isolated on their surfaces. The existence of these dusts is likely to reduce the heat dissipation effect of the distribution box, so cleaning is required. During the cleaning process, the filter screen usually needs to be disassembled. During the disassembly process, it is easy to shake the filter screen, causing the dust intercepted between its gaps to fall into the interior of the distribution box, resulting in the accumulation of dust inside the distribution box and increasing the cleaning difficulty.

Detailed implementation manners

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1. This embodiment aims to facilitate the solution of the problem that when the filter screen is disassembled, it is easy to shake the filter screen, resulting in the dust intercepted between its gaps falling into the interior of the distribution box, causing dust accumulation inside the distribution box and increasing the cleaning difficulty. Please refer to Figures 1 - 11 , an outdoor distribution box, including a distribution box main body 1. A fixed frame 15 is fixed to the inner wall of the distribution box main body 1. A dust-proof filter screen 16 is arranged on the inner wall of the fixed frame 15, and the dust-proof filter screen 16 is hinged at the inner wall of the fixed frame 15;

[0034] A third guide rod 32 is fixed to the inner wall of the fixed frame 15. A third slider 34 is slidably arranged on the outer wall of the third guide rod 32, that is, the third slider 34 is slidably sleeved on the third guide rod 32. A third return spring 33 is sleeved on the third guide rod 32, and both ends of the third return spring 33 are fixed to the inner wall of the fixed frame 15 and the outer wall of the third slider 34 respectively;

[0035] A third chute 35 is formed on the outer wall of the third slider 34. A fourth guide rod 36 is fixed to the inner wall of the third chute 35. A fourth return spring 37 is sleeved on the fourth guide rod 36. One end of the fourth return spring 37 is fixed to the inner wall of the third chute 35, and the other end of the fourth return spring 37 is fixed to the outer wall of the fourth slider 38. A fourth slider 38 is slidably sleeved on the fourth guide rod 36. A fourth return spring 37 is arranged between the third chute 35 and the fourth slider 38. A rotating shaft 39 is rotatably arranged inside the fourth slider 38, and both ends of the rotating shaft 39 are rotatably arranged on the outer wall of the dust-proof filter screen 16;

[0036] And during the rotation of the dust-proof filter net 16, it is necessary to always maintain the blocking effect of the dust-proof filter net 16 on the ventilation slots 4 to prevent dust from entering the main body 1 of the distribution box during the rotation of the dust-proof filter net 16. Therefore, during the rotation of the dust-proof filter net 16, the rotating shaft 39 rotatably arranged at its top will rotate circumferentially. During the circumferential movement of the rotating shaft 39, the fourth slider 38 sleeved on its outer wall will move synchronously. It should be noted that the rotating shaft 39 can rotate within the fourth slider 38. At this time, the fourth slider 38 will be driven to slide downward along the third chute 35, slide along the outer wall of the fourth guide rod 36 during the downward sliding process, and compress the fourth return spring 37 during the downward sliding process to facilitate subsequent reset. And because the inclination of the dust-proof filter net 16 continuously abuts against the third slider 34, the third slider 34 is urged to slide along the guidance of the third guide rod 32, and continuously compress the third return spring 33 during the sliding process to facilitate subsequent reset;

[0037] An electric telescopic rod 3 is installed on the inner wall of the main body 1 of the distribution box, and a lifting inclined block 8 is fixed at the output end of the electric telescopic rod 3;

[0038] A first guide rod 13 is fixed on the outer wall of the fixed frame 15. A first slider 14 is slidably arranged on the outer wall of the first guide rod 13. A first return spring 131 is arranged between the first slider 14 and the fixed frame 15. The first return spring 131 is sleeved outside the first guide rod 13. A second inclined block 9 is fixed on the outer wall of the first slider 14. The inclined surfaces of the second inclined block 9 and the lifting inclined block 8 are in mutual contact. When it is necessary to clean the distribution box, first start the electric telescopic rod 3. After the electric telescopic rod 3 is started, it drives the lifting inclined block 8 at the output end to rise. During the rising process of the lifting inclined block 8, the inclined surface on the lifting inclined block 8 abuts against the inclined surface on the second inclined block 9. The abutment causes the second inclined block 9 to be stressed and drive the first slider 14 to move along the first guide rod 13 in the direction of compressing the first return spring 131;

[0039] A first abutting plate 10 is fixed on the outer wall of the second inclined block 9. A first guide rod 11 for abutting against the dust-proof filter net 16 is fixed on the outer wall of the first abutting plate 10. A first ball 12 is arranged on the outer wall of the first guide rod 11. During the movement of the second inclined block 9, it drives the first abutting plate 10 to move synchronously. The first abutting plate 10 continuously approaches the dust-proof filter net 16, causing the first guide rod 11 on the outer wall of the first abutting plate 10 to continuously abut against the dust-proof filter net 16, causing the dust-proof filter net 16 to be stressed and rotate along the hinge joint with the fixed frame 15 after being abutted, and its rotation direction is the side direction inclined towards the outside of the ventilation slot 4.

[0040] Outdoor distribution boxes are electrical equipment, which have the characteristics of small volume, easy installation, special technical performance, fixed position, unique configuration function, unrestricted by the site, widespread application, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect. Therefore, they are applied to various construction sites.

[0041] At present, during the use of existing outdoor distribution boxes on the market, since the distribution box itself will continuously generate a certain amount of heat during use, usually at least two sides of the distribution box are set as hollow settings. However, a simple hollow setting easily allows external dust to enter the interior of the distribution box, resulting in the generation of static electricity when the dust amount in the distribution box reaches a certain limit. Because existing distribution boxes usually have slots on the side walls of two or more sides of the distribution box, and dust-proof nets for dust prevention are arranged in the slots. After these dust-proof nets are used for a period of time, a thick layer of dust will be isolated on their surfaces. The existence of this dust easily reduces the heat dissipation effect of the distribution box, so cleaning is required. During the cleaning process, the filter screen usually needs to be disassembled. During the disassembly process, it is easy to shake the filter screen, causing the dust intercepted in its gaps to fall into the interior of the distribution box, resulting in the accumulation of dust inside the distribution box and increasing the cleaning difficulty. Therefore, a self-cleaning outdoor distribution box is needed.

[0042] In this embodiment: By starting the electric telescopic rod 3, the dust-proof filter screen 16 is promoted to rotate along the hinge with the fixed frame 15, so that the dust-proof filter screen 16 is in a state of tilting outward from the distribution box main body 1. The tilt can promote that when cleaning the dust-proof filter screen 16 at this time, due to the overall tilt of the dust-proof filter screen 16, the dust blocked in the gaps of the dust-proof filter screen 16 will not fall into the distribution box main body 1 during the cleaning process, but will only fall onto the surface of the inclined plane 5 opened on the ventilation groove 4 along the inclined corner, and then fall to the outside along the inclined plane 5. In this way, the problem that the dust on the dust-proof filter screen 16 easily falls into the distribution box main body 1 and accumulates when the dust-proof filter screen 16 needs to be cleaned is solved.

[0043] Therefore, during the rotation of the dust-proof filter screen 16, the third slider 34 can always adjust its position following the rotation of the dust-proof filter screen 16, and the dust-proof filter screen 16 can also always drive the fourth slider 38 to slide and adapt along the third chute 35 on the outer wall of the third slider 34, so as to ensure that the dust-proof filter screen 16 can always play a dust-proof role for the contour in the ventilation groove 4 during the rotation process, preventing gaps from appearing during the rotation process and allowing dust to enter.

[0044] Embodiment 2. The purpose of this embodiment is to promote the solution of the problem in Embodiment 1 of how to clean the dust intercepted on the surface of the dust-proof filter screen 16 during the process of tilting the dust-proof filter screen 16. Please refer to Figures 1 - 11, an outdoor distribution box. A second chute 25 is formed in the lifting inclined block 8. A second slider 26 is slidably arranged on the inner wall of the second chute 25. A third guide rod 29 for knocking the dust-proof filter net 16 is fixed to the outer wall of the second slider 26. A third ball 30 is arranged at the end of the third guide rod 29;

[0045] A second guide rod 27 is also fixed to the outer wall of the second slider 26. A second ball 28 is arranged at the end of the second guide rod 27. A track groove 31 for guiding the movement of the second guide rod 27 is formed in the inner wall of the distribution box main body 1;

[0046] A distribution box power distribution main board 2 is installed on the inner wall of the distribution box main body 1;

[0047] During the process of starting the electric telescopic rod 3 to drive the lifting inclined block 8 to move downward, the downward movement of the lifting inclined block 8 will cause the third guide rod 29 protruding outside the lifting inclined block 8 to continuously move downward synchronously with the downward movement of the lifting inclined block 8. During the process of the third guide rod 29 following the lifting inclined block 8 to move downward, the third guide rod 29 will drive the third ball 30 at its end to slide along the track groove 31, and because the track groove 31 is set as shown in the appendix Figure 5The shown trajectory is such that for every certain distance of sliding down, it bends towards one side due to the curvature of the trajectory groove, and as the sliding distance increases, the amplitude of each bend of the trajectory groove towards one side also increases accordingly. Therefore, when the third guide rod 29 slides downward, it is affected by the trajectory of the trajectory groove 31. Whenever the third guide rod 29 slides past the curved trajectory of the trajectory groove 31, a lateral force will be exerted on the third guide rod 29. After being subjected to the lateral force, the third guide rod 29 drives the second slider 26 at its end to slide along the second chute 25. During the sliding process of the second slider 26, the third guide rod 29 on its outer wall moves synchronously. At this time, the third guide rod 29 and the third ball 30 at its end will quickly move towards the direction close to the outer wall of the dust-proof filter net 16, and strike the outer wall of the dust-proof filter net 16. The strike will cause the entire dust-proof filter net 16 to vibrate. Moreover, the dust-proof filter net 16 is already in a state of tilting outward at this time. Therefore, the dust falling off the dust-proof filter net 16 due to the strike will fall onto the inclined surface 5 and then fall outside the distribution box main body 1. It should be noted that when the second guide rod 27 continues to move downward, it will drive the second slider 26 to move laterally to the initial position as the bending ends. When continuing to move downward, at this time, the dust-proof filter net 16 will also tilt more towards the outside. In order to be able to continue striking the outside of the dust-proof filter net 16, the third guide rod 29 needs to move a greater distance to strike the dust-proof filter net 16. Therefore, when the third guide rod 29 continues to move downward along the trajectory groove 31, as the downward movement length increases, the amplitude of the outward bend of the trajectory groove 31 each time will also become larger and larger, causing the lateral movement distance of the third guide rod 29 each time to also become larger and larger. This is to facilitate continuously striking the dust-proof filter net 16 during the process of the dust-proof filter net 16 rotating and tilting, so that the dust inside the dust-proof filter net 16 can be shaken off onto the inclined surface 5 and slide down through the strike during the tilting process.

[0048] In this embodiment: By driving the lifting inclined block 8 to move downward through the electric telescopic rod 3, the third guide rod 29 and the third ball 30 at its end will quickly move towards the direction close to the outer wall of the dust-proof filter net 16, and strike the outer wall of the dust-proof filter net 16. Moreover, as the dust-proof filter net 16 continuously tilts, the amplitude of the strike on the outer wall of the dust-proof filter net 16 by the third guide rod 29 and the third ball 30 at its end will also continuously adapt accordingly, so as to achieve the effect of still being able to strike the outer wall of the dust-proof filter net 16 when it rotates to different angles. In this way, during the rotation process of the dust-proof filter net 16, the dust intercepted in its internal pores can be continuously struck and removed.

[0049] Embodiment Three. The intention of this embodiment is to facilitate the solution that although the strike in Embodiment Two can cause the dust in the internal pores of the dust-proof filter net 16 to fall off, a part of the dust will adhere to the surface of the dust-proof filter net 16, and it is difficult for the strike to make it fully detached. The adhered surface will also affect the filtering effect of the dust-proof filter net 16 and the overall heat dissipation effect of the distribution box main body 1. Please refer toFigures 1 - 11 , an outdoor distribution box, the outer wall of the distribution box body 1 is provided with a ventilation groove 4, the inner wall of the ventilation groove 4 is provided with an inclined surface 5, a first slide groove 17 is provided on the dust filter 16, a second guide rod 18 is fixed to the inner wall of the first slide groove 17, two first scrapers 20 are slidably arranged on the second guide rod 18, the two first scrapers 20 are both fixed with a second return spring 19, the second return spring 19 is sleeved on the second guide rod 18, a connecting rod 22 is fixed to the outer wall of the first scraper 20, a second scraper 23 is fixed to one end of the connecting rod 22, a cleaning brush 21 for cleaning the dust filter 16 is fixed to the first scraper 20 and the second scraper 23, and the cleaning brush 21 abuts against the dust filter 16;

[0050] During the inclination of the dust filter 16, the inclination of the dust filter 16 will cause the third inclined surface block 24 of its outer wall to move synchronously in a circular motion. During the circular motion of the two third inclined surface blocks 24, they will collide with the interfering inclined surface 7 of the outer wall of the first inclined surface block 6. The interfering causes the two third inclined surface blocks 24 to separate. As the circular motion continues, the separation distance of the two third inclined surface blocks 24 gradually increases. As the two third inclined surface blocks 24 separate, the third inclined surface block 24 slides with the corresponding first scraper 20 along the second guide rod 18 in the first slide groove 17. , and during the sliding process, the corresponding second return spring 19 will be compressed to facilitate subsequent resetting, and at this time, the cleaning brush 21 and the connecting rod 22 and the second scraper 23 move synchronously, that is, at this time, the cleaning brushes 21 on both sides simultaneously clean the dust adhering to the outer wall of the dust filter 16, and the cleaning brush 21 scrapes off the dust on the surface of the dust filter 16, and then the scraped dust falls onto the surface of the inclined surface 5 and falls to the outside along the inclined surface, completing the cleaning of the dust on the surface of the dust filter 16, and it should be noted that the whole process is completed in one go during the tilting process of the dust filter 16;

[0051] A third inclined surface block 24 is fixed to the outer wall of the first scraper 20 , a first inclined surface block 6 for contacting the third inclined surface block 24 is fixed to the inclined surface 5 , and a contact inclined surface 7 is provided on the outer wall of the first inclined surface block 6 .

[0052] In this embodiment: during the process of tilting the dust filter 16, the cleaning brushes 21 on both sides simultaneously clean the dust stuck to the outer wall of the dust filter 16, and the cleaning brushes 21 scrape the dust on the surface of the dust filter 16, and then the scraped dust falls onto the surface of the inclined surface 5 and falls to the outside along the inclined surface, thereby completing the cleaning of the dust on the surface of the dust filter 16. It should be noted that the entire process is completed in one go during the tilting process of the dust filter 16, that is, all processes occur during the tilting process of the dust filter 16, and all processes end together after the tilting is completed.

[0053] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0054] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
