Description

TECHNICAL FIELD

[0001] The application relates to the technical field of power distribution cabinet groups, and particularly relates to an intelligent moisture-proof power distribution cabinet group. BACKGROUND

[0002] The power distribution cabinet group is generally composed of multiple power distribution cabinets and can realize more complex power control and protection functions, support intelligent monitoring, data acquisition and automatic control, and is widely used in intelligent power grids, industrial parks and other places requiring large-scale power distribution and management. The power distribution cabinet group is one of the infrastructures of the intelligent power grid and undertakes the core functions of power distribution, control and protection.

[0003] For example, the patent with the patent name "power distribution cabinet and power distribution cabinet group" disclosed in the prior art with the publication number "CN116404538A" discloses that when a single power distribution cabinet in the power distribution cabinet group needs to be disassembled or replaced, the connecting blocks installed on the upper and lower surfaces and the left and right surfaces of the single power distribution cabinet are disassembled, so that the single power distribution cabinet can slide forward and backward, and the single power distribution cabinet can be disassembled from the power distribution cabinet group. At this time, the power distribution cabinet located on the upper side of the single power distribution cabinet can be fixed through the connecting blocks on the left and right sides, and then the single power distribution cabinet in the power distribution cabinet group can be independently disassembled. Then, the connecting blocks on the disassembled single power distribution cabinet are disassembled and installed on the new power distribution cabinet, so that the new power distribution cabinet can be installed on the power distribution cabinet group through sliding, and then the disassembled connecting blocks are assembled together, so that the independent disassembly and replacement of the single power distribution cabinet in the power distribution cabinet group can be completed. When more or fewer power distribution cabinets need to be installed, the number of connecting blocks that can be installed on the cabinet group base can be changed by changing the number of base groups, so that all power distribution cabinets that need to be installed on the bottom layer can be stably installed on the cabinet group base. The patent with the patent name "power distribution cabinet dehumidification assembly and power distribution cabinet" disclosed in the prior art with the publication number "CN119209229A" discloses that a plurality of dehumidification fans are installed on the two vertical side walls of the horizontal cylinder and are distributed equidistantly along the length direction of the horizontal cylinder. A sealing frame is arranged between the dehumidification fan and the horizontal cylinder, the sealing frame can compensate the gap between the dehumidification fan and the horizontal cylinder, prevent air from being discharged from the gap to affect the blowing effect of the dehumidification fan, and when the dehumidification fan blows air into the power distribution cabinet, the air in the horizontal cylinder is extracted, so that negative pressure is generated in the horizontal cylinder. The air in the power distribution cabinet enters the horizontal cylinder through the air inlet hopper and the penetrating hole. At the same time, the electric heating sheet is started, the electric heating sheet heats the air in the horizontal cylinder, so that the moisture in the air is heated and dried. When the dehumidification fan blows out the hot air, the moisture in the air in the power distribution cabinet can be further heated and dried.

[0004] The intelligent power distribution cabinet group in the prior art can heat the air in the horizontal cylinder by the electric heating sheet, so that the effect of dehumidification, moisture-proof and waterproof is achieved, but multiple dehumidification fans are needed, which consumes a large amount of electric energy, so that the intelligent power distribution cabinet group cannot save energy when used in the smart grid, and the moisture in the air in the power distribution cabinet is heated and dried by the dehumidification fan, so that the effect of dehumidification and moisture-proof is achieved, but the temperature of the air in the power distribution cabinet is increased, which is not convenient for cooling the inside of the power distribution cabinet, thereby affecting the use of the intelligent power distribution cabinet group, so that the intelligent moisture-proof power distribution cabinet group is provided to solve the above problems.

[0038] The lower end of the flow guide pipe 18 is connected with the space in the cabinet shell 1 below the fixed plate 14, the flow guide pipe 18 is arranged in a "7" shape structure, the upper end of the flow guide pipe 18 is connected with the ventilation cooling pipe 17 through a hose, the inner side wall of the ventilation cooling pipe 17 is installed with a row of nozzles, the inside of the fixed plate 14 is installed with a single-rotation reciprocating screw rod 15, the outer side of the single-rotation reciprocating screw rod 15 is threadedly connected with a "U"-shaped control frame 16, the rear of the left and right sides of the control frame 16 is connected with the ventilation cooling pipe 17, the gas conveying pipe 302 is arranged below the fixed plate 14, and is used for conveying the air dehumidified by the condensing dehumidifier 3 to the lower of the fixed plate 14 to be dehumidified again by the multi-stage moisture absorbing assembly, the intermittent exhaust mechanism includes a sealing piston assembly 20 which is slidingly connected with the inner wall of the exhaust pipe 6, the outer side of the exhaust pipe 6 is provided with an exhaust hole 61, the sealing piston assembly 20 is used for covering and sealing the exhaust hole 61, the front end of the sealing piston assembly 20 is connected with a "U"-shaped control box 10, the front end of the exhaust pipe 6 is connected with the rear side of the control box 10 through a return spring 21, the return spring 21 is sleeved on the outer side of the front end of the sealing piston assembly 20, the left and right sides of the control box 10 are provided with the ventilation cooling pipe 17, and the ventilation cooling pipe 17 constitutes a front and rear sliding structure through the control box 10.

[0039] Firstly, the whole intelligent moisture-proof power distribution cabinet group is moved to the working area, and then the intelligent moisture-proof power distribution cabinet group can collect voltage, current, power and other data to provide real-time operation information for the smart grid. When the temperature sensor 9 detects that the temperature in the cabinet shell 1 is high, ventilation and heat dissipation are needed. At this time, the condensing dehumidifier 3 is started at the same time. The fan in the condensing dehumidifier 3 rotates to suck the air outside into the condensing dehumidifier 3. At this time, the air is filtered by the dustproof filter plate 4 before entering the condensing dehumidifier 3. Then the moisture in the air is condensed into water droplets and discharged through the drain pipe 301. The dehumidified air enters the cabinet shell 1 below the fixed plate 14 through the air conveying pipe 302. At this time, the air first flows from bottom to top and then from top to bottom through the molecular sieve assembly 12 and the through slot 131 in turn, so that the air flows in a wave-shaped curved path. This not only prolongs the flow distance of the air from the outside to the inside, but also changes the flow direction of the air multiple times, so that the air can contact the molecular sieve assembly 12 multiple times, increasing the chance of air moisture being intercepted, thereby facilitating the molecular sieve assembly 12 to dehumidify the air multiple times, thereby further removing the moisture in the air. At the same time, through the use of the molecular sieve assembly 12, the power consumption can be reduced, so that the intelligent power distribution cabinet group can save electricity and energy when used in the smart grid. Then the air without moisture enters the ventilation and cooling pipe 17 through the flow guide pipe 18 and the hose. The air is sprayed into the cabinet shell 1 through the spray pipe inside the ventilation and cooling pipe 17. At the same time, the motor in the fixed plate 14 is started. The motor drives the single-rotation reciprocating screw rod 15 to rotate. The single-rotation reciprocating screw rod 15 rotates to drive the control frame 16 connected with the outer thread to move back and forth. Then the control frame 16 drives the ventilation and cooling pipe 17 to move back and forth, so that the ventilation and cooling pipe 17 uniformly sprays the dehumidified air into the cabinet shell 1, so as to cool and heat the heat around the mounting rail frame 7.

[0040] When the ventilation and cooling pipe 17 moves backward and contacts the front side of the control frame 10, the ventilation and cooling pipe 17 continues to move backward to push the control frame 10 backward. Then the control frame 10 drives the sealing piston assembly 20 to move backward. At this time, the return spring 21 is compressed and stored. When the sealing piston assembly 20 moves backward, it is separated from the corresponding air vent 61. At this time, the air in the cabinet shell 1 is discharged outward through the air vent 61. When the ventilation and cooling pipe 17 moves forward and separates from the front side of the control frame 10, the stored energy of the return spring 21 will automatically drive the sealing piston assembly 20 to move forward to reset, so that the sealing piston assembly 20 seals the air vent 61. Through repeated operation, the cabinet shell 1 can be intermittently ventilated and cooled. Through the design of a reasonable ventilation structure, not only can the external moisture be prevented from entering the cabinet shell 1, but also the air circulation in the cabinet shell 1 can be ensured to avoid the excessive heat in the cabinet shell 1 affecting the use.

[0041] Later, the sealing plate 11 can be pulled to remove the molecular sieve component 12 from the outer shell 1 of the cabinet for replacement, or it can be regenerated by heating or drying, so that the molecular sieve component 12 can be reused, which is economical and environmentally friendly.

[0042] Example 2: Based on Example 1, the intelligent moisture-proof power distribution cabinet in this example allows the gas discharged from exhaust pipe 6 to re-enter the condenser dehumidifier 3 for condensation and dehumidification, facilitating the recirculation of the discharged gas. See attached diagram for the specific structure. Figures 1-4 and appendix Figures 7-10 As shown, the outer sealing sleeve of the exhaust pipe 6 is provided with a gathering sleeve 19, which is located outside the exhaust port 61. A circulation pipe 5 is installed through the outer side of the gathering sleeve 19. The other end of the circulation pipe 5 passes through the inside of the cabinet shell 1 and is inserted into the condenser dehumidifier 3. When the air inside the cabinet shell 1 is discharged outward through the exhaust port 61, the discharged air is collected by the gathering sleeve 19. Then, the air in the gathering sleeve 19 enters the condenser dehumidifier 3 through the circulation pipe 5. A one-way valve is installed in the circulation pipe 5, so that the circulation pipe 5 can circulate the discharged air.

[0043] Example 3: The intelligent moisture-proof power distribution cabinet in this example, based on Example 1, can detect whether the sealing strip inside the sealed door 2 is damaged, facilitating timely replacement of the damaged sealing strip. See attached diagram for the specific structure. Figure 4 and attached Figure 11 As shown, a detection frame 8 with a mesh-like interior is installed inside the front side of the cabinet shell 1 via a manual telescopic rod 81. A connecting spring 82 is nested on the outside of the manual telescopic rod 81. A pressure sensor 22 is installed on the cabinet shell 1 located directly below the detection frame 8. Silica gel particles for moisture absorption are placed inside the detection frame 8, which has a U-shaped structure.

[0044] When the sealing strip on the inner side of the detection door 2 is damaged, the sealing performance of the detection door 2 is poor. At this time, external moisture will enter the cabinet shell 1. The moisture first passes through the internal mesh detection frame 8. The silica gel particles in the detection frame 8 absorb moisture and increase in weight. The detection frame 8 will automatically move downward and squeeze the manual telescopic rod 81. At the same time, after the detection frame 8 moves down to a certain position, it will apply a certain pressure to the pressure sensor 22. The pressure sensor 22 then transmits this signal to the central processing module. The central processing module then controls the alarm installed on the cabinet shell 1 to sound an alarm, so as to promptly remind the staff to replace the sealing strip, thereby completing a series of tasks.

[0045] Although the present application has been described in detail with reference to the foregoing embodiments, the technical solutions recorded in the foregoing embodiments can be modified, or some of the technical features can be replaced by equivalent features, by those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
