Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinet equipment, in particular to a moisture-proof low-voltage power distribution cabinet for outdoor use. Background Art

[0002] In the power system, the moisture-proof low-voltage distribution cabinet used outdoors is an important device to ensure power distribution and control. Its main function is to reasonably distribute low-voltage electric energy in outdoor environments and to protect, control and monitor circuits. It is usually installed in streets, factories, communities and other places to provide stable power for various electrical equipment. It is a key hub in the process of power transmission and use, and is crucial to ensuring the reliability and safety of power supply.

[0003] However, there are many deficiencies in traditional outdoor moisture-proof low-voltage distribution cabinets. In terms of moisture-proof, although some distribution cabinets are equipped with ventilation slots, they lack an effective automatic adjustment mechanism and cannot flexibly adjust the internal space layout according to weather changes. On rainy days, rainwater can easily enter the cabinet through the ventilation slots, causing internal components to be damaged by moisture, affecting the normal operation and service life of the distribution cabinet. Even if some distribution cabinets have certain water-proof structures, it is difficult to effectively handle excess rainwater, which may cause water accumulation, further increasing safety hazards. In terms of heat dissipation, traditional distribution cabinets have poor heat dissipation effects. On sunny days, the ventilation slots cannot be fully utilized to achieve efficient heat dissipation, causing components to work in a high-temperature environment for a long time, accelerating the aging of components and reducing their performance and reliability. In addition, in terms of structural design, traditional distribution cabinets lack effective sealing measures for ventilation slots. Not only are they prone to leakage on rainy days, but they may also be affected by dust and debris entering during daily use, affecting ventilation effects and electrical performance. It is difficult to meet the strict requirements of modern power systems for moisture-proof, heat dissipation and protection performance of distribution cabinets. Summary of the invention

[0019] (III) Beneficial effects

[0020] The present invention provides a moisture-proof low-voltage power distribution cabinet for outdoor use. It has the following beneficial effects:

[0021] (I) The moisture-proof low-voltage distribution cabinet used outdoors can realize automatic displacement of the mounting plate on rainy days, so as to prevent the mounting plate from being too close to the No. 2 ventilation slot, causing the internal components to be exposed to rain and get damp on rainy days. When the rainy day is over, the rainwater in the water collecting frame will evaporate through the No. 1 ventilation slot, causing the water collecting frame to move up and reset, that is, the mounting plate is reset, which continues to facilitate the heat dissipation of the components on the mounting plate, thereby realizing the heat dissipation of the mounting plate close to the No. 2 ventilation slot on sunny days, and automatically shifting on rainy days to prevent the components from getting damp, realizing automated work throughout the process, greatly improving the practicality of the distribution cabinet.

[0022] (ii) For the moisture-proof low-voltage distribution cabinet used outdoors, when more and more rainwater accumulates in the water collecting frame, the water level will eventually reach the water outlet, that is, the continuously input excess rainwater will be transported to the outside of the water collecting frame through the water outlet, and output to the outside of the outer shell through the water outlet trough after being blocked by the isolation strip, thereby achieving automatic discharge of excess rainwater while ensuring the gravity of the water collecting frame, greatly improving the stability of the distribution cabinet. In the process of the bearing plate moving up to cause the installation plate to shift, the bonding strip and the connecting strip will be driven to move up on the inner surface of the back plate at the same time, so that the outer surface of the bonding strip gradually fits the fixing strip. When the bonding strip is completely fitted with the fixing strip, the blockage of the No. 2 ventilation slot is completed, and the No. 2 ventilation slot is automatically closed on rainy days, further avoiding the possibility of rainwater entering the inner part of the outer shell through the No. 2 ventilation slot and causing the components to get damp, thereby greatly improving the protection effect of the components.

[0023] (III) For the moisture-proof low-voltage distribution cabinet used outdoors, when the water-collecting frame moves downward, the corrugated bag will be squeezed at the same time, thereby increasing the internal air pressure of the corrugated bag and outputting it to the expansion strip in the filling groove in the isolation strip, causing the expansion strip to begin to expand and finally squeeze and fit on the outer surface of the water-collecting frame near the water outlet, thereby automatically sealing the gap between the isolation strip and the water-collecting frame when the excess rainwater is discharged, avoiding the problem of rainwater leakage through the gap between the isolation strip and the water-collecting frame, further improving the use stability of the distribution cabinet, and improving the protection effect of components. When the corrugated bag is squeezed, its internal air pressure will be simultaneously transmitted to the internal cavity of the fitting strip, thereby causing the inclined surface of the fitting strip to begin to expand outward, thereby achieving complete sealing of the No. 2 ventilation slot, further avoiding the risk of leakage in the No. 2 ventilation slot, and maximizing the protection effect of the components on the mounting plate, improving the service life of the components, and reducing the number of maintenance times.

[0041] Second embodiment: Figures 1 to 8As shown, the linkage mechanism 7 includes a fixing strip 71, which is buckled on the inner surface of the back panel 3. The fixing strip 71 is arranged opposite to the No. 2 ventilation slot 5, wherein five fixing strips 71 are arranged at fixed intervals, and a through slot is reserved on the fixing strip 71.

[0044] A filling groove 76 is formed on the surface of the isolation strip 67 away from the back plate 3 . The filling groove 76 is fixedly filled with an expansion strip 77 . The internal cavity of the expansion strip 77 is connected to the internal cavity of the corrugated bag 75 .

[0045] The interior of the bonding strip 73 is configured to be hollow, the inclined surface of the bonding strip 73 is made of a deformable rubber material, and the internal cavity of the bonding strip 73 is communicated with the internal cavity of the corrugated bag 75 .

[0046] During operation, when the power distribution cabinet needs to be used, the power distribution cabinet can be moved to a designated location outdoors, and the closing door 2 can be opened. Then, the electronic component module can be installed through the mounting groove 614 on the mounting plate 613. After the installation is completed, the closing door 2 can be closed to complete the overall installation of the power distribution cabinet. Under normal working conditions, the mounting plate 613 is close to the back plate 3 for ventilation and heat dissipation, and the internal air circulation is completed through the reserved ventilation grooves No. 1 4 and No. 2 ventilation grooves 5. When it rains, rainwater will enter the collection cover 61 through the ventilation groove No. 1 4 on the top of the outer shell 1, and enter the water collecting frame 62 through the collection cover 61. As the water in the water collecting frame 62 increases, the gravity of the water collecting frame 62 increases, that is, it will descend along the mounting strip 63 in the outer shell 1. When the water collecting frame 62 descends, it will pull the top of the No. 1 pulling belt 69, so that the movable frame 610 connected to the bottom of the No. 1 pulling belt 69 moves up, and then the supporting plate 617 moves up. When the supporting plate 617 moves up, it will pull the No. 2 pulling belt 616, that is, through the action of the guide rod 615, the mounting plate 613 is moved toward the side of the closed door 2 as a whole, until the mounting plate 613 is finally located in the middle of the outer shell 1, away from the back plate 3, so that the mounting plate 613 is automatically shifted on rainy days, and the mounting plate 613 is prevented from being too close to the No. 2 ventilation slot 5, causing the internal components to be exposed to rainwater and get wet on rainy days. When the rainy day ends, the rainwater in the water collecting frame 62 will evaporate through the No. 1 ventilation slot 4, so that the water collecting frame 62 moves up and resets, that is, the mounting plate 613 is The vent 65 is used to cool the components on the mounting plate 613, and the mounting plate 613 is placed close to the second ventilation slot 5 for heat dissipation on sunny days, and the mounting plate 613 is automatically moved to prevent the components from getting wet on rainy days. The whole process is automated, which greatly improves the practicality of the power distribution cabinet. When the rainwater in the water collecting frame 62 accumulates more and more, the water level will eventually reach the water outlet 64, that is, the excess rainwater continuously input will be transported to the outside of the water collecting frame 62 through the water outlet 64, and will be output to the outside of the outer shell 1 through the water outlet 65 through the isolation strip 67, so as to ensure the gravity of the water collecting frame 62 while automatically draining out the excess rainwater, which greatly improves the stability of the power distribution cabinet. When the mounting plate 613 is displaced, the fitting strip 73 and the connecting strip 72 are simultaneously driven to move up on the inner surface of the back plate 3, so that the outer surface of the fitting strip 73 gradually fits the fixing strip 71. When the fitting strip 73 is completely fitted with the fixing strip 71, the blocking of the No. 2 ventilation slot 5 is completed, and the No. 2 ventilation slot 5 is automatically closed on rainy days, further preventing rainwater from entering the outer shell 1 through the No. 2 ventilation slot 5 and causing the probability of components getting damp, thereby greatly improving the protection effect of the components. When the water collecting frame 62 moves downward, it squeezes the corrugated bag 75 at the same time, thereby increasing the internal air pressure of the corrugated bag 75 and outputting it to the expansion strip 77 in the filling slot 76 in the isolation strip 67, causing the expansion strip 77 to start to expand.Finally, it is squeezed and fitted on the outer surface of the water collecting frame 62 near the water outlet 64, so as to automatically seal the gap between the isolation strip 67 and the water collecting frame 62 when the excess rainwater is discharged, so as to avoid the problem of rainwater leakage through the gap between the isolation strip 67 and the water collecting frame 62, further improve the use stability of the power distribution cabinet, and improve the protection effect of components. When the corrugated bag 75 is squeezed, its internal air pressure will be synchronously transmitted to the internal cavity of the fitting strip 73, so that the inclined surface of the fitting strip 73 begins to expand outward, so as to achieve complete sealing of the second ventilation slot 5, further avoid the risk of leakage in the second ventilation slot 5, and maximize the protection effect of the components on the mounting plate 613, improve the service life of the components, and reduce the number of maintenance times.
