Description

Technical Field

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

[0002] The outdoor distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection. Therefore, it is used in various construction sites.

[0003] During the use of the outdoor distribution boxes currently available on the market, since the distribution boxes themselves will continue to generate a certain amount of heat during use, at least two or more sides of the distribution boxes are usually set to be hollow. However, the simple hollow setting makes it easy for external dust to enter the interior of the distribution box, resulting in static electricity when the amount of dust in the distribution box reaches a certain limit. This is because the existing distribution boxes usually have grooves on two or more side walls of the distribution box, and dust-proof nets are provided in the grooves for dust prevention. After these dust-proof nets have been used for a period of time, a thick layer of dust will be isolated on their surfaces. The presence of such dust will easily reduce the heat dissipation effect of the distribution box, so they need to be cleaned. During the cleaning process, the filter usually needs to be disassembled. During the disassembly process, the filter is easily shaken, causing the dust intercepted between the gaps to fall into the interior of the distribution box, resulting in dust accumulation inside the distribution box, which increases the difficulty of cleaning. Therefore, a self-cleaning outdoor distribution box is needed. Summary of the invention

[0004] The present invention provides an outdoor distribution box, which has the beneficial effects of preventing dust from falling into the box during the cleaning of the filter, facilitating the cleaning of the filter inside and outside, and always not affecting the filtering function when cleaning the filter.

[0009] As an optional solution for an outdoor distribution box described in the present invention, the dust filter is provided with a first slide groove, a second guide rod is fixed to the inner wall of the first slide groove, two first scrapers are slidably arranged on the second guide rod, a second return spring is fixed to the two first scrapers, the second return spring is sleeved on the second guide rod, a connecting rod is fixed to the outer wall of the first scraper, a second scraper is fixed to one end of the connecting rod, a cleaning brush for cleaning the dust filter is fixed to the first scraper and the second scraper, and the cleaning brush is in contact with the dust filter.

[0010] As an optional solution for an outdoor distribution box described in the present invention, a third inclined plane block is fixed to the outer wall of the first scraper, a first inclined plane block for resisting the third inclined plane block is fixed to the inclined plane, and a resisting inclined plane is provided on the outer wall of the first inclined plane block.

During the rotation of the dust filter, the dust filter can always perform dust prevention on the contour of the air groove to prevent dust from entering due to gaps caused by rotation.

[0015] In the present invention, as the dust filter is tilted, the outer wall of the dust filter can be knocked, and as the dust filter continues to tilt, the amplitude of the knocking on the outer wall of the dust filter will also continue to adapt, so as to achieve the effect of still being able to knock on the outer wall of the dust filter when the dust filter is rotated to different angles. In this way, during the rotation of the dust filter, the dust intercepted in the internal pores of the dust filter can be continuously knocked and removed.

[0016] In the present invention, while the dust filter is tilting, the cleaning brushes on both sides simultaneously clean the dust stuck on the outer wall of the dust filter, and the cleaning brushes scrape the dust on the surface of the dust filter, and then the scraped dust falls onto the surface of the inclined surface and falls to the outside along the inclined surface, thereby completing the cleaning of the dust on the surface of the dust filter. It should be noted that the entire process is completed in one go during the tilting of the dust filter, that is, all processes occur during the tilting of the dust filter, and all processes end together after the tilting is completed.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: This embodiment aims to solve the problem that the filter is easily shaken during the removal process, causing the dust trapped in the gaps to fall into the inside of the distribution box, resulting in dust accumulation inside the distribution box and increasing the difficulty of cleaning. Figure 1-Figure 11 , an outdoor distribution box, comprising a distribution box body 1, a fixing frame 15 is fixed to the inner wall of the distribution box body 1, a dust filter 16 is arranged on the inner wall of the fixing frame 15, and the dust filter 16 is hinged at the inner wall of the fixing frame 15; A third guide rod 32 is fixed to the inner wall of the fixed frame 15, and a third slider 34 is slidably provided 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, and a third return spring 33 is sleeved on the third guide rod 32, and two ends of the third return spring 33 are respectively fixed to the inner wall of the fixed frame 15 and the outer wall of the third slider 34; A third slide groove 35 is provided on the outer wall of the third slide groove 35, a fourth guide rod 36 is fixed to the inner wall of the third slide groove 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 slide groove 35, the other end of the fourth return spring 37 is fixed to the outer wall of the fourth slide groove 38, a fourth slide groove 38 is slidably sleeved on the fourth guide rod 36, a fourth return spring 37 is provided between the third slide groove 35 and the fourth slide groove 38, a rotating shaft 39 is rotatably provided on the inner wall of the fourth slide groove 38, and both ends of the rotating shaft 39 are rotatably provided on the outer wall of the dust filter 16; And in the process of the dust filter 16 rotating, it is necessary to keep the dust filter 16 blocking the air groove 4 to prevent dust from entering the distribution box body 1 in the process of the dust filter 16 rotating. Therefore, in the process of the dust filter 16 rotating, it will lead the rotating shaft 39 set at the top to rotate in a circle, and in the process of the rotating shaft 39 moving in a circle, it will lead the fourth slider 38 set on the outer wall to move synchronously. It should be noted that the rotating shaft 39 is rotatable in the fourth slider 38. At this time, the fourth slider 38 will be led to slide downward along the third slide groove 35, and slide along the outer wall of the fourth guide rod 36 during the sliding process, and the fourth return spring 37 is compressed during the sliding process to facilitate subsequent reset. In addition, due to the inclination of the dust filter 16, the third slider 34 is prompted to slide along the guide of the third guide rod 32, and the third return spring 33 is continuously compressed during the sliding process to facilitate subsequent reset. An electric telescopic rod 3 is installed on the inner wall of the distribution box body 1, and a lifting inclined plane block 8 is fixed to the output end of the electric telescopic rod 3; A first guide rod 13 is fixed to the outer wall of the fixed frame 15, a first slider 14 is slidably provided on the outer wall of the first guide rod 13, a first return spring 131 is provided 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 plane block 9 is fixed to the outer wall of the first slider 14, the inclined plane of the second inclined plane block 9 and the inclined plane of the lifting inclined plane block 8 abut against each other, when it is necessary to clean the distribution box, the electric telescopic rod 3 is first started, after the electric telescopic rod 3 is started, the lifting inclined plane block 8 at the output end is lifted, during the lifting process of the lifting inclined plane block 8, the inclined plane on the lifting inclined plane block 8 and the inclined plane on the second inclined plane block 9 abut against each other, the abutment forces the second inclined plane block 9 to carry the first slider 14 along the first guide rod 13 to move in the direction of compressing the first return spring 131; A first contact plate 10 is fixed to the outer wall of the second inclined surface block 9, and a first guide rod 11 for contacting the dust filter 16 is fixed to the outer wall of the first contact 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 surface block 9, it is prompted to move synchronously with the first contact plate 10, and the first contact plate 10 continuously approaches the dust filter 16, prompting the first guide rod 11 on the outer wall of the first contact plate 10 to continuously contact the dust filter 16, prompting the dust filter 16 to rotate along the hinge with the fixed frame 15 after being contacted, and the rotation direction is inclined toward one side outside the air vent 4.

[0031] The outdoor distribution box is an electrical equipment with the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint and environmental protection. Therefore, it is used in various construction sites.

[0032] During the use of the outdoor distribution boxes currently available on the market, since the distribution boxes themselves will continue to generate a certain amount of heat during use, at least two or more sides of the distribution boxes are usually set to be hollow. However, the simple hollow setting makes it easy for external dust to enter the interior of the distribution box, resulting in static electricity when the amount of dust in the distribution box reaches a certain limit. This is because the existing distribution boxes usually have grooves on two or more side walls of the distribution box, and dust-proof nets are provided in the grooves for dust prevention. After these dust-proof nets have been used for a period of time, a thick layer of dust will be isolated on their surfaces. The presence of such dust will easily reduce the heat dissipation effect of the distribution box, so they need to be cleaned. During the cleaning process, the filter usually needs to be disassembled. During the disassembly process, the filter is easily shaken, causing the dust intercepted between the gaps to fall into the interior of the distribution box, resulting in dust accumulation inside the distribution box, which increases the difficulty of cleaning. Therefore, a self-cleaning outdoor distribution box is needed.

[0033] In the present embodiment: by starting the electric telescopic rod 3, the dust filter 16 is prompted to rotate along the hinge with the fixed frame 15, so that the dust filter 16 is prompted to be in a state of being inclined toward the outside of the distribution box body 1. The inclination can cause the dust filter 16 to be cleaned at this time. Since the dust filter 16 is tilted as a whole, the dust blocked in the gap of the dust filter 16 will not fall into the distribution box body 1 during the cleaning process, but will only fall along the inclined corner to the surface of the inclined surface 5 opened on the air vent 4, and then fall to the outside along the inclined surface 5, thereby solving the problem that the dust on the dust filter 16 is easy to fall into the distribution box body 1 and accumulate when the dust filter 16 needs to be cleaned.

[0034] Therefore, during the rotation of the dust filter 16, the third slider 34 can always follow the rotation of the dust filter 16 to adjust its position, and the dust filter 16 can also always slide and adapt along the third slide groove 35 of the outer wall of the third slider 34 with the fourth slider 38, thereby enabling the dust filter 16 to always prevent the contour of the air groove 4 from being dust-proof during the rotation, thereby preventing dust from entering due to gaps during the rotation.

[0035] Embodiment 2: This embodiment is intended to facilitate solving the problem of how to clean the dust intercepted on the surface of the dust filter 16 during the process of tilting the dust filter 16 in Embodiment 1. Figure 1-Figure 11 An outdoor distribution box, a lifting ramp block 8 is provided with a second slide groove 25, a second slider 26 is slidably provided on the inner wall of the second slide groove 25, a third guide rod 29 for knocking the dust filter 16 is fixed on the outer wall of the second slider 26, and a third ball 30 is provided at the end of the third guide rod 29; A second guide rod 27 is also fixed to the outer wall of the second slider 26, and 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 opened on the inner wall of the distribution box body 1; The inner wall of the distribution box body 1 is installed with a distribution box main board 2; When the electric telescopic rod 3 is started to move the lifting ramp block 8 downward, the downward movement of the lifting ramp block 8 will cause the third guide rod 29 protruding from the lifting ramp block 8 to continuously move downward synchronously with the downward movement of the lifting ramp block 8. When the third guide rod 29 moves downward following the lifting ramp block 8, the third guide rod 29 will slide along the track groove 31 with the third ball 30 at the end thereof. Figure 5As shown in the track, that is, every time the third guide rod 29 slides down a certain distance, the track groove bends to one side, and as the sliding distance increases, the amplitude of the track groove bending to one side each time also increases. Therefore, when the third guide rod 29 slides downward, it is affected by the track of the track groove 31. Whenever the third guide rod 29 slides down and passes through the curved track of the track groove 31, the third guide rod 29 will be subjected to a lateral force. After the third guide rod 29 is subjected to the lateral force, it slides along the second slide groove 25 with the second slider 26 at the end. During the sliding process of the second slider 26, the third guide rod 29 with the outer wall moves synchronously. At this time, the third guide rod 29 and the third ball 30 at its end will quickly move toward the direction close to the outer wall of the dust filter 16, and knock on the outer wall of the dust filter 16. The knocking will cause the dust filter 16 to vibrate as a whole. At this time, the dust filter 16 is already in a state of tilting outward, so knocking on the dust filter The dust dropped by 16 will fall onto the inclined surface 5 and fall to the outside of the distribution box body 1. It should be noted that when the second guide rod 27 continues to move downward, it will move the second slider 26 horizontally to the initial position as the bending ends. When it continues to move downward, the dust filter 16 will also be more inclined toward the outside. In order to continue to knock on the outside of the dust filter 16, the third guide rod 29 moves a larger distance to knock on the dust filter 16. Therefore, when the third guide rod 29 continues to move downward along the track groove 31, as the length of the downward movement increases, the trajectory amplitude of the track groove 31 bending outward each time will also become larger, so that the distance of the third guide rod 29 moving horizontally each time will also become larger, so that it is convenient to continuously knock on the dust filter 16 during the process of rotating and tilting the dust filter 16, so that the dust inside the dust filter 16 can fall onto the inclined surface 5 and slide down through the knocking vibration during the tilting process.

[0036] In this embodiment: by moving the lifting ramp block 8 downward with the electric telescopic rod 3, the third guide rod 29 and the third ball 30 at its end will quickly move toward the direction close to the outer wall of the dust filter 16, and knock on the outer wall of the dust filter 16, and as the dust filter 16 continues to tilt, the amplitude of the knocking of the third guide rod 29 and the third ball 30 at its end on the outer wall of the dust filter 16 will also continue to adapt accordingly, so as to achieve the effect of still being able to knock on the outer wall of the dust filter 16 when the dust filter 16 rotates to different angles, so that during the rotation of the dust filter 16, the dust intercepted in the inner pores thereof can be continuously knocked and removed.

[0037] Embodiment 3, this embodiment is intended to promote the solution of the problem that although knocking can make the dust in the internal pores of the dust filter 16 fall off, some of the dust will adhere to the surface of the dust filter 16, and it is difficult to fully separate it by knocking. The sticking surface will also affect the filtering effect of the dust filter 16 and the overall heat dissipation effect of the distribution box body 1. Please refer to Figure 1-Figure 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; 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; 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 .

[0038] 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.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
