Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and more specifically, to a dehumidification device for an outdoor distribution box and a distribution box thereof. Background Art

[0002] The distribution box is mainly used to assemble and enclose the functional components of electrical circuits such as switchgear, measuring instruments, protective appliances and auxiliary equipment. It plays a direct and key role in the convenience of low-voltage control circuits and the safety and stability of electrical circuits, and has an important protective role. The distribution box has small size, easy installation, special technical performance, fixed position, unique configuration function, and is not restricted by the site. It is widely used. At present, the distribution box can be divided into outdoor distribution boxes and indoor distribution boxes. Due to the influence of environmental humidity, outdoor distribution boxes are very prone to failure due to moisture. Therefore, the existing outdoor distribution boxes are mostly dried and protected by dehumidification.

[0003] For example, patent announcement number CN208127684U discloses a ventilation and dehumidification multifunctional distribution box, including a distribution box body and an electrical component mounting frame, wherein the electrical component mounting frame is equidistantly connected inside the distribution box body, and the first vent and the second vent are symmetrically opened on the shells on both sides of the distribution box body, and the openings of the first vent and the second vent are embedded with vent covers, wherein a ventilation fan is embedded and fixed inside the second vent, and the bottom of the distribution box body is rotatably connected with a rotating roller through a rotating bearing. In this utility model, a dehumidifying drying plate is rotatably connected with the rotating roller, and the dehumidifying drying plate located inside the distribution box body above the rotating roller can be dehumidified and absorb water vapor, and the dehumidifying drying plate below the rotating roller is located outside the distribution box body and is exposed to sunlight and air-dried, thereby drying the desiccant, and then rotating and recycling it, thereby reducing the frequency of replacing the desiccant.

[0004] In the above patent, the inventor believes that although the patent realizes the recyclable utilization of the dehumidification material used for dehumidification of the distribution box when in use, it is affected by the unstable environmental factors outside the box, such as the unstable lighting conditions, humidity and dust concentration. First, the dehumidification material located outdoors is affected by dust adhesion, which reduces the air dehumidification permeability. Second, the insufficient lighting conditions affect the drying effect of the dehumidification material. Third, the influence of humidity easily reduces the dryness of the dehumidification material located outdoors, thereby failing to meet the advantages of repeated reuse of the dehumidification material. Therefore, how to ensure the dehumidification effect of the outdoor distribution box while also meeting the continuous and reliable recycling of dehumidification is a technical problem that needs to be solved at present.

[0022] Technical effects and advantages of the present invention:

[0023] 1. The present invention provides two pairs of dehumidification drying plates on the dehumidification frame as drying materials for the air inlet position of the heat dissipation inlet. The dehumidification drying plates can absorb moisture and dry the heat dissipation air. The weight increase effect caused by the moisture absorption of the dehumidification drying plates can enable the rotation and adjustment of the drying positions of the multiple dehumidification drying plates.

[0025] 3. The present invention provides a dust removal brush that rotates along with the drying and dehumidifying plate. The rotation of the dust removal brush can facilitate the periodic cleaning of dust on the dust filter. The dust-proof filtering property of the dust filter is utilized to reduce the effect of dust adhesion on the drying and dehumidifying plate and affect ventilation. The purpose is to periodically clean the dust filter, which can improve the reliability of heat dissipation, ventilation and drying.

[0026] 4. The present invention provides an openable and closable drying cover at the drying port, and combines the outdoor environment detection module to monitor the data of the outdoor environment such as light intensity, humidity and dustiness. When the outdoor environmental conditions permit, the dehumidification drying plate rotated to the drying port position by gravity can use sunlight to achieve irradiation drying. When the outdoor environmental adjustment does not allow, the built-in heating component of the drying cover can achieve the effect of drying. Therefore, the drying process of the dehumidification drying plate is achieved by switching between the two drying modes, which can improve the reliability of the dehumidification cycle reuse of the dehumidification drying plate.

DETAILED DESCRIPTION

[0037] 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.

[0038] Combined with reference Figure 1-Figure 3 The present invention provides a dehumidification device for an outdoor distribution box, comprising a box body 1, which is the outer shell of the outdoor distribution box. A rainproof roof 2 is arranged on the top of the box body 1, which can provide rainproof protection for the box body 1. A heat dissipation air inlet 3 and a heat dissipation air outlet 31 are respectively opened on both sides of the box body 1. The heat dissipation air inlet 3 can provide an air inlet for heat dissipation, and the heat dissipation air outlet 31 can provide an air outlet for heat dissipation. A fan can be arranged in the box body 1 of the present application, and the fan should correspond to the inner port of the heat dissipation air outlet 31, so that the fan can provide air-cooled heat dissipation treatment for the box body 1. A heat dissipation sealing structure 4 is arranged on the box body 1, and the heat dissipation sealing structure 4 is used to seal the port of the heat dissipation air outlet 31.

[0039] The above-mentioned outdoor distribution box dehumidification device also includes a dehumidification frame 5, a counterweight assembly 6, an outer cover 8, a dust filter 9 and an elastic connecting piece 10.

[0040] Combined with reference Figure 4 A dust filter 17 is fixedly connected to the heat dissipation outlet 31, and the dust filter 17 can provide dust protection for the heat dissipation outlet 31. The heat dissipation blocking structure 4 includes a telescopic device 41 fixedly connected to the other side of the box body 1 and an air outlet blocking plate 42 fixedly connected to the output end of the telescopic device 41. The air outlet blocking plate 42 is used to block the port of the heat dissipation outlet 31.

[0041] A temperature sensor 16 is provided on the inner wall of the box body 1. The temperature sensor 16 can be used to detect the working temperature of the power distribution facilities in the box body 1. The temperature sensor 16 can be electrically connected to the telescopic device 41 through a controller.

[0042] Specifically, when the fan at the heat dissipation air outlet 31 is working, the heat dissipation air outlet 31 has an outgoing wind effect, and external moisture is not easy to enter the box body 1 through the heat dissipation air outlet 31. When the temperature sensor 16 detects that the working temperature in the box body 1 does not require heat dissipation, the output end of the telescopic device 41 can be extended to allow the air outlet blocking plate 42 to block the heat dissipation air outlet 31. This can avoid the entry of moisture when the heat dissipation air outlet 31 is not working, and therefore, there is no need to perform dehumidification treatment at the heat dissipation air outlet 31.

[0043] Combined with reference Figure 5 The dehumidification frame 5 is rotatably connected to one side of the box body 1 where the heat dissipation air inlet 3 is opened. At least two pairs of dehumidification drying plates 7 are arranged on the dehumidification frame 5, and one of the dehumidification drying plates 7 is located at the port position of the heat dissipation air inlet 3. This community is heavy.

[0044] The dehumidification frame 5 includes a fixed plate 51 rotatably connected to one side of the box body 1 through a damping shaft, two pairs of fixed supports 52 fixedly connected to the fixed plate 51, and a fixed outer ring 53 fixedly connected to the two pairs of fixed supports 52. The fixed plate 51, the two pairs of fixed supports 52 and the fixed outer ring 53 surround two pairs of drying intervals. The resistance shaft used by the fixed plate 51 can adopt a low-damping shaft structure. Under the condition of increasing a certain damping effect, while satisfying the rotation of the fixed plate 51 under the weight of the drying and dehumidifying plate 7, the swing degree of the dehumidification frame 5 under the weight rotation can be reduced. The dehumidifying and drying plate 7 is fixedly connected The advantage of forming two pairs of drying zones in the drying zone is that, by utilizing the fan-shaped structure of the dehumidifying and drying plate 7, when it becomes heavier due to dehumidification and absorption of moisture, the fixed disk 51 can rotate under the action of the gravity of the dehumidifying and drying plate 7 until the dehumidifying and drying plate 7 is moved to the position directly below by gravity, so that the dehumidifying and drying plate 7 at that position can be conveniently reused for drying. Therefore, while the multiple dehumidifying and drying plates 7 continue to dehumidify the air at the heat dissipation outlet 3 position in sequence, the dehumidifying and drying plates 7 with reduced dehumidification performance and adjusted position can be effectively dried and reused.

[0045] Combined with reference Figure 7 The dehumidification drying plate 7 is provided with dehumidification inclined holes 71, and the number of the dehumidification inclined holes 71 is multiple. The dehumidification drying plate 7 can be made into a plate structure by a dehumidification material, and the dehumidification drying plate 7 and the dehumidification frame 5 can slide on the side of the box body 1 and the side of the outer cover 8. By reducing the amount of the gap, the singleness of the air circulation of the heat dissipation air inlet 3 can be guaranteed. The inclined setting of the dehumidification inclined holes 71 can increase the contact area with the air, which can increase the dehumidification amount of the air passing through the dehumidification inclined holes 71 and ensure the adequacy of moisture adsorption.

[0046] Specifically, when one of the dehumidifying and drying plates 7 is located at the heat dissipation air inlet 3, the dehumidifying and drying plate 7 can dehumidify the incoming heat dissipation air. When the dehumidifying and drying plate 7 becomes heavier due to dehumidification and water absorption, under the action of gravity, the dehumidifying and drying plate 7 can make the fixed plate 51 rotate on the box body 1 until the dehumidifying and drying plate 7 rotates to the position of the drying port 81 due to gravity, and then stop the action. At this time, the dehumidifying and drying plate 7 can be repeatedly dried, and the previous dehumidifying and drying plate 7 can be dehumidified at the corresponding position of the heat dissipation air inlet 3, so as to use the gravity generated by dehumidification and water absorption to prompt the dehumidifying and drying plate 7 to rotate its position, so as to meet the effect of automatic drying replacement, so as to improve the convenience of the dehumidifying and drying plate 7 for drying and repeated reuse.

[0047] Combined with reference Figure 6 The number of the counterweight assemblies 6 is two pairs, and the counterweight assemblies 6 are arranged on the dehumidification frame 5 .

[0048] The counterweight assembly 6 includes a counterweight tube 61 fixedly connected to the periphery of the fixed outer ring 53, a rolling groove 62 opened in the counterweight tube 61, and a counterweight ball 63 movably connected to the rolling groove 62. The two pairs of counterweight tubes 61 are distributed on the cross dividing line of the fixed outer ring 53, and the counterweight tubes 61 are arranged at an angle, and the counterweight ball 63 can roll in the rolling groove 62.

[0049] Specifically, when the dehumidification and drying plate 7 becomes heavier due to moisture absorption and rotates out of alignment, the counterweight tube 61 is arranged on the cross dividing line of the fixed outer ring 53, and the counterweight tube 61 is arranged tilted. The counterweight ball 63 located at the highest position can change the counterweight point position in the counterweight tube 61 to apply the counterweight force to the rotational force of the dehumidification and drying plate 7. This can promote the rotation performance of the dehumidification and drying plate 7 for position adjustment and ensure rotation reliability.

[0050] The outer cover 8 is fixedly connected to one side of the box body 1, and the outer cover 8 is located on the outside of the dehumidification frame 5. A drying port 81 is opened on the outer cover 8. A drying cover 12 for opening and closing the drying port 81 is provided on the outer cover 8. A heating component 13 is provided on the inner side of the drying cover 12. The heating component 13 can use an electric heating element to provide drying heating.

[0051] Combined with reference Figure 8 The drying cover 12 is rotatably connected to the outer cover 8 through a hinge, a sealing strip 18 is fixedly connected to the periphery of the drying cover 12, a telescopic device 19 is hinged on the box body 1, and the output end of the telescopic device 19 is hinged on the drying cover 12. The drying cover 12 of the present application is covered on the drying port 81 through the sealing strip 18, and the outer cover 8 can achieve a relatively sealed effect.

[0052] Specifically, the telescopic device 19 pulls the drying cover plate 12 to open and close on the outer cover 8 to effectively expose the position of the drying port 81, so that the dehumidification drying plate 7 inside the drying port 81 can be dried by sunlight to meet the reuse rate of the dehumidification drying plate 7.

[0053] The dust filter 9 is fixedly passed through the outer cover 8. In the present application, the outer cover 8 is provided with an embedding groove for installing the dust filter 9, and the size of the embedding groove matches the heat dissipation air inlet 3. The dust filter 9 is provided to provide dustproof protection for the dehumidification drying plate 7 at the heat dissipation air inlet 3, so as to avoid the blockage of the dehumidification inclined hole 71 caused by dust directly adhering to the dehumidification drying plate 7, thereby preventing the reliability of air dehumidification of the dehumidification drying plate 7 from being affected.

[0054] Combined with reference Fig. 9 The elastic connecting member 10 is rotatably connected to the outer cover 8, and the elastic connecting member 10 is fixedly connected to the dehumidification frame 5. Two pairs of dust removal brushes 11 for dust removal of the dust filter 9 are fixedly connected to the elastic connecting member 10. In the present application, the dust removal brush 11 adopts an anti-static brush, and the dust removal brush 11 corresponds horizontally to the fixed support 52.

[0055] The elastic connecting member 10 includes an assembly plate 101 rotatably connected to the outer cover 8 via an axis, two pairs of rotating seats 102 fixedly connected to the assembly plate 101, a torsion spring rotating shaft 103 arranged on each rotating seat 102 and a rotating block 104 arranged on the torsion spring rotating shaft 103. The rotating block 104 is rotatably connected to the rotating seat 102 via the torsion spring rotating shaft 103. In the present application, the torsion spring reset direction of the rotating block 104 rotatably connected to the rotating seat 102 via the torsion spring rotating shaft 103 is inward, and the torsion spring rotating shaft 103 is composed of a torsion spring and a rotating shaft.

[0056] The assembly plate 101 is fixedly connected to the fixed disk 51 through a shaft, one end of the dust removal brush 11 is fixedly connected to the rotating block 104, and the brush part of the dust removal brush 11 is in active contact with the outer surface of the dustproof filter 9.

[0057] Specifically, in the process that the dehumidification drying plate 7 becomes heavier due to moisture absorption and rotates, the fixed disk 51 can drive the assembly plate 101 to rotate. Since the dust removal brush 11 is horizontally corresponding to the position of the fixed support 52, the dust removal brush 11 can perform brush-type dust removal by contacting the outer surface of the dust filter 9. By reducing the amount of dust on the dust filter 9, the dehumidification drying plate 7 at the position of the heat dissipation air inlet 3 is prevented from being affected by dust adhesion and affecting ventilation and dehumidification. In this way, the reliability of heat dissipation, ventilation and drying can be improved.

[0058] It is worth mentioning that a rotatable elastic reset connection is provided for the dust removal brush 11 through the combination of the rotating seat 102, the rotating block 104 and the torsion spring shaft 103, so that when the drying cover 12 is opened, the drying cover 12 can adaptively lift the dust removal brush 11 and rotate it upward. After the drying cover 12 is closed, the dust removal brush 11 can be reset by utilizing the rotation reset property of the torsion spring shaft 103, thereby achieving the coordinated use effect of the dust removal brush 11 and the drying cover 12.

[0059] A solar photovoltaic panel 14 and an outdoor environment detection module 15 are provided on the rainproof roof 2. The outdoor environment detection module 15 includes a light sensor, a humidity sensor and a dust concentration sensor. The solar photovoltaic panel 14 can provide photoelectric energy for the distribution box used outdoors. The solar photovoltaic panel 14 can be used in conjunction with the existing photoelectric energy storage system, which can improve energy utilization. The outdoor environment detection module 15 can be electrically connected to the telescopic device 19 and the heating component 13 through a controller.

[0060] Specifically, the light intensity, humidity and dust level of the environment outside the box body 1 are monitored through the outdoor environment detection module 15. When the light intensity, humidity and dust level conditions allow the dehumidification drying plate 7 to be irradiated and dried, the drying cover 12 can be opened to use sunlight to irradiate and dry the dehumidification drying plate 7 located at the drying port 81; conversely, when the light intensity, humidity and dust level conditions do not allow, the heating component 13 built into the drying cover 12 can directly dry the dehumidification drying plate 7. Therefore, by switching between the two drying methods to achieve the drying process of the dehumidification drying plate, the drying energy consumption of the reused dehumidification drying plate 7 can be reduced, and at the same time, the reliability of the dehumidification cycle reuse of the dehumidification drying plate 7 can be met.

[0061] It is worth noting that in the present application, the outdoor setting position of the box body 1 should make the dehumidification drying plate 7 face the positive sun side. In addition, when the dehumidification performance of the dehumidification drying plate 7 is reduced due to long-term repeated use, the outer cover 8 can be connected to the box body 1 by bolts. By removing the outer cover 8, the dehumidification drying plate 7 on the dehumidification frame 5 can be removed. In this embodiment, the connection of the dehumidification drying plate 7 in the drying zone can adopt a detachable connection structure and method, such as fasteners such as a snap structure.

[0062] In the present application, the telescopic device can use a telescopic motor as the telescopic device, and the electrical components in the present application can be program-controlled by a controller.

[0063] A distribution box includes the outdoor distribution box dehumidification device as described above. The distribution box of the present application adopts the dehumidification device of the above distribution box to ensure the dehumidification effect of the outdoor distribution box while also meeting the continuous and reliable recycling of dehumidification.
