Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet with a moisture-proof function. Background Art

[0002] The power distribution cabinet is the final equipment of the power distribution system, which is mainly used for power distribution, control and protection. Since there are a large number of electrical components inside the power distribution cabinet, they will generate high heat during use, which will cause the internal temperature of the power distribution cabinet to rise. Therefore, in order to ensure the normal operation of the electrical components, the power distribution cabinet usually has ventilation holes for heat dissipation. However, when the outside is in a humid environment, moisture can easily enter the interior of the power distribution cabinet through the ventilation holes, causing moisture in the power distribution cabinet, which has an adverse effect on the normal operation and safety of the power distribution cabinet.

[0003] Existing power distribution cabinets usually use hygroscopic materials in the cabinet to absorb and lock moisture in the air, while maintaining good air permeability to ensure smooth air circulation inside the cabinet to achieve moisture-proof effect. However, hygroscopic materials have certain limitations in use. After absorbing moisture and becoming saturated, they need to be replaced quickly and are difficult to recycle. This causes inconvenience in operation and affects the moisture-proof effect of the cabinet. To this end, we propose a power distribution cabinet with moisture-proof function.

[0037] By using the first vent 2 and the second vent 4 in combination, normal air circulation can be achieved between the inner cabinet 3 and the outer cabinet 1 to ensure the normal ventilation and heat dissipation effect of the inner cabinet 3. The upper surfaces of the outer cabinet 1 and the inner cabinet 3 can be covered and protected by the ceiling 27. At the same time, the hot air discharged from the inner cabinet 3 by the No. 1 fan 9 and the No. 2 fan 11 can be blocked and diverted, so that the hot air is controlled to linger around the first vent 2 first to reduce the humidity of the air around the first vent 2. The heating wire assembly 7 can be isolated from the electrical components arranged inside the inner cabinet 3 by the partition 5. The guide port 6 can cooperate with the first vent 2 and the second vent 4 for air circulation and transmission. At the same time, the filter screen arranged at the guide port 6 and the first vent 2 and the second vent 4 can filter the outside air to prevent dust and foreign matter from entering the inner cabinet 3 through air circulation.

[0038] On both sides of the middle of the inner bottom surface of the inner cabinet 3, heating wire assemblies 7 are fixedly installed. On both sides of the middle of the inner surface of the inner cabinet 3, assembly plate assemblies 8 are fixedly installed together. The assembly plate assembly 8 includes an assembly vertical frame and an assembly horizontal frame. In the middle of the upper surface of the inner cabinet 3, an opening is provided, and a first blower 9 is fixedly embedded through the inner surface of the opening.

[0039] The space between the partition 5 and the inner bottom surface of the inner cabinet 3 can be heated by the heat generated by the heating wire assemblies 7, so that it is in a dry state, which is convenient for improving the dryness when the outside air circulates through. The assembly plate assembly 8 can be used for the installation and use of electrical components. The first blower 9 and the second blower 11 are used to control the air circulation direction and rate in the inner cabinet 3.

[0040] On both sides of the inner surface of the outer cabinet 1 and both sides of the outer surface of the inner cabinet 3, partition grooves 10 are provided in a non-contact state. In the middle of the upper surface of the partition groove 10, an opening is provided, and a second blower 11 is fixedly embedded through the inner surface of the opening. On the inner bottom surface of the partition groove 10, an assembly frame 12 is placed. On one side of the inner top surface of the assembly frame 12, a first ventilation port 14 is provided. On one side of the inner bottom surface of the assembly frame 12, a second ventilation port 15 is provided.

[0041] In the middle of the inner bottom surface of the assembly frame 12, a desiccant packet 16 is placed. On both sides of the middle of the inner bottom surface of the assembly frame 12, isolation nets 13 are fixedly installed. The isolation nets 13 are located at the intervals between the first ventilation port 14 and the desiccant packet 16 and between the second ventilation port 15 and the desiccant packet 16. On the upper and lower parts of the rear end of the outer surface of the assembly frame 12, support wheels 28 are fixedly installed. On the upper and lower parts of the front end of the outer surface of the assembly frame 12, butt ears 17 in a protruding "匚" shape are fixedly provided.

[0042] The partition groove 10 is used for the movable adjustment of the assembly frame 12. Through the misaligned arrangement of the first ventilation port 14 and the second ventilation port 15, when the outside air circulates into the inner cabinet 3, the air can be controlled to pass through the desiccant packet 16 for circulation, and then the desiccant packet 16 is used to absorb the moisture in the air to reduce the humidity of the air. At the same time, the isolation nets 13 can further filter foreign matters in the air. Through the butt ears 17, they can be butt-connected with the butt blocks 24. In the state where the butt blocks 24 squeeze the assembly frame 12, combined with the contact and rolling support state of the support wheels 28 and the inner surface of the rear end of the partition groove 10, it is convenient to control the lifting adjustment of the assembly frame 12 in the partition groove 10.

[0043] Cabinet doors 18 are movably installed on both sides of the front end of the outer surface of the outer cabinet 1 through hinges, and sealing blocks 19 are provided in the middle of the rear end of the outer surface of the cabinet door 18. The size of the sealing block 19 is equal to the gap size between the partition 5 and the front end of the outer surface of the inner cabinet 3 and the rear end of the outer surface of the cabinet door 18. An adjustment bin 20 is fixedly provided on one side of the front end of the outer surface of the cabinet door 18. An adjustment screw 21 is movably inserted and installed in the middle of the inner bottom surface of the adjustment bin 20. The other end of the adjustment screw 21 is movably inserted into the middle of the inner top surface of the adjustment bin 20. A micro motor 22 is fixedly installed on the upper surface of the adjustment bin 20.

[0044] The output end of the micro motor 22 passes through the adjustment chamber 20 and is connected to the end of the adjustment screw 21. The lower part of the outer surface of the adjustment screw 21 is spirally sleeved with an adjustment screw ring 23. The upper and lower parts of the rear end of the outer surface of the adjustment screw ring 23 are fixed with docking blocks 24 that match the docking ears 17. A limiting groove 25 is provided on one side of the rear end of the outer surface of the cabinet door 18. The docking block 24 passes through the limiting groove 25 and extends outside.

[0045] The cabinet door 18 cooperates with the sealing block 19 to seal the interval between the inner cabinet 3 and the cabinet door 18. The micro motor 22 drives the adjusting screw 21 to rotate counterclockwise, and the adjusting screw ring 23 provided on the adjusting screw 21 can be controlled to be raised and lowered, and is in a stable lifting state under the limiting action of the limiting groove 25. When the cabinet door 18 is in a closed state, the docking block 24 provided on the adjusting screw ring 23 will be docked and inserted into the docking ear 17, thereby realizing the indirect control of the assembly frame 12 by the adjusting screw ring 23, and the lifting and lowering adjustment of the adjusting screw ring 23 drives the assembly frame 12 to be lifted and lowered synchronously.

[0046] An integrated controller mechanism 26 is fixedly mounted at the front middle of the outer surface of the cabinet door 18, and the integrated controller mechanism 26 includes a temperature sensor, a humidity sensor, an instruction preset module, an analysis module and a control module;

[0047] The temperature sensor and humidity sensor are both arranged at the front and rear ends of the outer surface of the integrated controller mechanism 26. The temperature sensor is used to monitor the temperature data inside and outside the cabinet and obtain the real-time temperature value. The humidity sensor is used to monitor the humidity data inside and outside the cabinet and obtain the real-time humidity value and transmit it to the analysis module.

[0048] The command preset module is used to set the threshold intervals corresponding to the temperature and humidity inside and outside the cabinet, and to set the corresponding operation command signals of the heating wire assembly 7, the first fan 9, the second fan 11 and the micro motor 22 based on the threshold intervals;

[0049] Specifically, multiple temperature level threshold intervals are set, the standard temperature threshold interval inside the cabinet is set to WD, the upper temperature threshold interval is set to WDS, the lower temperature threshold interval is set to WDX, the standard temperature threshold interval outside the cabinet is set to WD', the upper temperature threshold interval is set to WDS', and the lower temperature threshold interval is set to WDX';

[0050] Set multiple humidity level threshold intervals, set the standard humidity threshold interval inside the cabinet to SD, the upper humidity threshold interval to SDS, and the lower humidity threshold interval to SDX, set the standard humidity threshold interval outside the cabinet to SD', the upper humidity threshold interval to SDS', and the lower humidity threshold interval to SDX';

[0051] Based on the standard temperature threshold interval WD and the lower temperature threshold interval WDX inside the cabinet, the standard temperature threshold interval WD' and the lower temperature threshold interval WDX' outside the cabinet, based on the standard humidity threshold interval SD and the lower humidity threshold interval SDX inside the cabinet, the standard humidity threshold interval SD' and the lower humidity threshold interval SDX' outside the cabinet, the corresponding operation command signal is set to that the heating wire assembly 7 and the micro motor 22 are both turned off, the No. 1 fan 9 exhausts air and the No. 2 fan 11 supplies air at normal power and is marked as instruction No. ①;

[0052] Based on the upper temperature threshold interval WDS inside the cabinet and the upper temperature threshold interval WDS' outside the cabinet, the corresponding operation command signal is set to turn off the heating wire assembly 7 and the micro motor 22, and the No. 1 fan 9 exhausts air and the No. 2 fan 11 supplies air at high power and is marked as command No. ②;

[0053] Based on the upper limit humidity threshold interval SDS inside the cabinet and the upper limit humidity threshold interval SDS' outside the cabinet, the corresponding operation command signal is set as the heating wire assembly 7 is running, the micro motor 22 is running counterclockwise, the No. 1 fan 9 is exhausting and the No. 2 fan 11 is delivering air at high power and marked as command No. ③;

[0054] The analysis module is used to analyze the received real-time temperature and humidity data, match it with the preset temperature and humidity threshold ranges, obtain the corresponding operation command signal according to the matching result and transmit it to the control module;

[0055] Specifically, the temperature and humidity values ​​inside and outside the cabinet monitored in real time by the temperature sensor and the humidity sensor are matched with the set threshold interval. If the match is successful, the corresponding operation command signal is obtained according to the matching result. If the current real-time temperature and humidity data are matched with different threshold intervals respectively, the corresponding operation command combination signal is obtained according to the matching result. The priority execution level of the operation command combination signal is the upper limit threshold interval of the temperature and humidity. If the combination command signals are all of the same type of upper limit thresholds, the priority execution level is the number of matching upper limit thresholds. If the combination command signals are of different types of upper limit thresholds, the priority execution level is the command signal represented by the humidity upper limit threshold.

[0056] For example: if the temperature and humidity values ​​inside and outside the cabinet monitored in real time by the temperature sensor and the humidity sensor are matched with the upper limit temperature threshold interval WDS inside the cabinet, the upper limit temperature threshold interval WDS' outside the cabinet, the upper limit humidity threshold interval SDS inside the cabinet, and the upper limit humidity threshold interval SDS' outside the cabinet respectively, the corresponding operation command signals are obtained as command No. ② and command No. ③, that is, command No. ② and command No. ③ are combined command operations. At this time, the matched temperature and humidity values ​​inside and outside the cabinet are both upper limit thresholds, and they are different types of upper limit thresholds occupied by temperature and humidity. In the combined command of command No. ② and command No. ③, command No. ③ will be executed as the priority command;

[0057] The control module is connected to the heating wire assembly 7, the first fan 9, the second fan 11 and the micro motor 22 via wireless signals, and controls them to perform corresponding operations according to the instruction content based on the received operation instruction signal.

[0058] When the present invention is in use, the real-time temperature and humidity data inside and outside the cabinet are first monitored by the integrated controller mechanism 26. When the humidity value outside the cabinet is monitored to reach the upper humidity threshold interval, the corresponding operation No. ③ instruction is obtained according to the corresponding interval. At this time, the integrated controller mechanism 26 can control the heating wire assembly 7 to start, and use the heating wire assembly 7 to control the range in which it is located to heat and dry, and control the operating power of the No. 1 fan 9 for exhaust and the No. 2 fan 11 for supplying air. In this case, the No. 1 fan 9 can quickly extract the air in the inner cabinet 3, thereby causing the inner cabinet 3 to present a negative pressure state;

[0059] In this case, the inner cabinet 3 can extract the outside air through the first ventilation port 2 and the second ventilation port 4, and cooperate with the high-power air supply of the second fan 11 to quickly input the outside air into the inner cabinet 3 and then circulate and discharge it. When the outside air is input into the inner cabinet 3, it will contact the heating wire assembly 7, thereby integrating with the dry environment in the range of the heating wire assembly 7 to improve the dryness of the outside air. The large displacement and rapid circulation of dry air is conducive to the rapid heat dissipation inside the inner cabinet 3 and the effect of ventilation and dehumidification.

[0060] Secondly, according to the operation instruction No. ③, the integrated controller mechanism 26 controls the micro motor 22 to drive the adjusting screw 21 to rotate counterclockwise. When the adjusting screw 21 is in the counterclockwise rotating state, the adjusting screw ring 23 spirally sleeved on its surface can move upward, and when the cabinet door 18 is in the closed state, the docking block 24 provided on the adjusting screw ring 23 will be docked and inserted into the docking ear 17, thereby realizing the indirect control of the adjusting screw ring 23 on the assembly frame 12. At this time, the ascending movement of the adjusting screw ring 23 can be used to control the assembly frame 12 to synchronously ascend and move along the partition groove 10 to the position where it is docked with the first vent 2;

[0061] At this time, the outside air entering through the first ventilation port 2 will pass through the isolation net 13 and contact the desiccant bag 16 set in the assembly frame 12. At the same time, the outside air transported by the second fan 11 will pass through the first ventilation port 14, pass through the isolation net 13 and contact the desiccant bag 16, and pass through the desiccant bag 16 and enter the inner cabinet 3 through the second ventilation port 15 for air circulation. In this case, when the outside air passes through the desiccant bag 16, the moisture contained in it will be absorbed by the desiccant bag 16, thereby reducing the moisture content in the outside air, and further improving the dryness of the air for ventilation, heat dissipation and dehumidification of the inner cabinet 3, so as to achieve the heat dissipation effect while playing a moisture-proof effect.

[0062] Example 2

[0063] See also Figure 6 - Figure 8 As shown, an integrated controller mechanism 26 is fixedly installed at the front middle of the outer surface of the cabinet door 18, and the integrated controller mechanism 26 includes a temperature sensor, a humidity sensor, an instruction preset module, an analysis module and a control module;

[0064] The temperature sensor and humidity sensor are both arranged at the front and rear ends of the outer surface of the integrated controller mechanism 26. The temperature sensor is used to monitor the temperature data inside and outside the cabinet and obtain the real-time temperature value. The humidity sensor is used to monitor the humidity data inside and outside the cabinet and obtain the real-time humidity value and transmit it to the analysis module.

[0065] The command preset module is used to set the threshold intervals corresponding to the temperature and humidity inside and outside the cabinet, and to set the corresponding operation command signals of the heating wire assembly 7, the first fan 9, the second fan 11 and the micro motor 22 based on the threshold intervals;

[0066] Specifically, multiple temperature level threshold intervals are set, the standard temperature threshold interval inside the cabinet is set to WD, the upper temperature threshold interval is set to WDS, the lower temperature threshold interval is set to WDX, the standard temperature threshold interval outside the cabinet is set to WD', the upper temperature threshold interval is set to WDS', and the lower temperature threshold interval is set to WDX';

[0067] Set multiple humidity level threshold intervals, set the standard humidity threshold interval inside the cabinet to SD, the upper humidity threshold interval to SDS, and the lower humidity threshold interval to SDX, set the standard humidity threshold interval outside the cabinet to SD', the upper humidity threshold interval to SDS', and the lower humidity threshold interval to SDX';

[0068] Based on the standard temperature threshold interval WD and the lower temperature threshold interval WDX inside the cabinet, the upper temperature threshold interval WDS' outside the cabinet, the standard humidity threshold interval SD' and the lower humidity threshold interval SDX' outside the cabinet, the corresponding operation command signal is set to the heating wire assembly 7 running, the micro motor 22 running clockwise, the No. 1 fan 9 supplying air and the No. 2 fan 11 exhausting air running at normal power and marked as No. ④ command;

[0069] Based on the upper temperature threshold interval WDS inside the cabinet, the upper temperature threshold interval WDS' outside the cabinet, the standard humidity threshold interval SD' outside the cabinet and the lower humidity threshold interval SDX', the corresponding operation command signal is set to turn off the heating wire assembly 7, the micro motor 22 runs clockwise, the No. 1 fan 9 supplies air and the No. 2 fan 11 exhausts air at high power and is marked as instruction No. ⑤;

[0070] The analysis module is used to analyze the received real-time temperature and humidity data, match it with the preset temperature and humidity threshold ranges, obtain the corresponding operation command signal according to the matching result and transmit it to the control module;

[0071] Specifically, the temperature and humidity values ​​inside and outside the cabinet monitored in real time by the temperature sensor and the humidity sensor are matched with the set threshold interval. If the match is successful, the corresponding operation command signal is obtained according to the matching result. If the current real-time temperature and humidity data are matched with different threshold intervals respectively, the corresponding operation command combination signal is obtained according to the matching result. The priority execution level of the operation command combination signal is the upper limit threshold interval of the temperature and humidity. If the combination command signals are all of the same type of upper limit thresholds, the priority execution level is the number of matching upper limit thresholds. If the combination command signals are of different types of upper limit thresholds, the priority execution level is the command signal represented by the humidity upper limit threshold.

[0072] The control module is connected to the heating wire assembly 7, the first fan 9, the second fan 11 and the micro motor 22 via wireless signals, and controls them to perform corresponding operations according to the instruction content based on the received operation instruction signal.

[0073] When the present invention is in use, the real-time temperature and humidity data inside and outside the cabinet are first monitored by the integrated controller mechanism 26. When the humidity value outside the cabinet is monitored to be in the standard and lower humidity threshold interval, the corresponding operation instruction ④ or ⑤ is obtained according to the corresponding interval. At this time, the integrated controller mechanism 26 can control the heating wire assembly 7 to start or shut down. When the heating wire assembly 7 is in the starting state, the heating wire assembly 7 is used to control the range in which it is located to heat and dry, and at the same time, the operating power of the No. 1 fan 9 for supplying air and the No. 2 fan 11 for exhausting air is controlled. In this case, the No. 2 fan 11 can quickly extract the air in the inner cabinet 3 through the first vent 2 and the second vent 4, thereby causing the inner cabinet 3 to present a negative pressure state;

[0074] At this time, with the high-power air supply of the No. 1 fan 9, the outside air can be quickly input into the inner cabinet 3 and then circulated and discharged. When the outside air is input into the inner cabinet 3, it will contact the heating wire assembly 7, thereby integrating with the dry environment in the range of the heating wire assembly 7 to improve the dryness of the outside air. When the heating wire assembly 7 executes the No. ⑤ instruction and is not started, the air can circulate on its own.

[0075] Secondly, according to the operation instruction ④ or ⑤, the integrated controller mechanism 26 controls the micro motor 22 to drive the adjusting screw 21 to rotate clockwise. When the adjusting screw 21 is in the clockwise rotation state, the adjusting screw ring 23 spirally sleeved on its surface can move downward, and when the cabinet door 18 is in the closed state, the docking block 24 provided on the adjusting screw ring 23 will be docked and inserted into the docking ear 17, thereby realizing the indirect control of the assembly frame 12 by the adjusting screw ring 23. At this time, the downward movement of the adjusting screw ring 23 can be used to control the assembly frame 12 to move synchronously downward along the partition groove 10 to the position where it docks with the second vent 4;

[0076] At this time, the dry air in the cabinet exhausted through the second vent 4 will pass through the isolation net 13 and contact the desiccant bag 16 arranged in the assembly frame 12, and pass through the desiccant bag 16 and be exhausted through the first vent 14. In this case, when the dry air in the cabinet passes through the desiccant bag 16, it will ventilate and dry the desiccant bag 16, thereby reducing the moisture content in the desiccant bag 16, maintaining its dry state, and realizing the repeated recycling of hygroscopic materials. At the same time, the moisture removed by the desiccant bag 16 will be exhausted from the cabinet along with the extraction of the No. 2 fan 11.

[0077] The above are only embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
