Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinet groups, and specifically relates to an intelligent moisture-proof distribution cabinet group. Background Art

[0002] Distribution cabinet groups are usually composed of multiple distribution cabinets, which can achieve more complex power control and protection functions, support intelligent monitoring, data collection, and automation control, and are widely used in places such as smart grids and industrial parks that require large-scale power distribution and management. Distribution cabinet groups are one of the infrastructure of smart grids and undertake the core functions of power distribution, control, and protection; For example, in the prior art, the patent with the publication number "CN116404538A" and the patent name "A Distribution Cabinet and a Distribution Cabinet Group" discloses that when a single distribution cabinet in the distribution cabinet group needs to be disassembled or replaced, the connection blocks installed on the upper, lower, left, and right surfaces of the single distribution cabinet are disassembled, so that the single distribution cabinet can be slid back and forth, and the single distribution cabinet can be disassembled from the distribution cabinet group. At this time, the distribution cabinet located above the single distribution cabinet can be fixed through the connection blocks on the left and right sides, and then the single distribution cabinet in the distribution cabinet group can be independently disassembled. Then, the connection blocks on the disassembled single distribution cabinet are disassembled and installed on the new distribution cabinet, so that the new distribution cabinet can be slid onto the distribution cabinet group, and then the disassembled connection blocks are assembled together, so that the independent disassembly and replacement of the single distribution cabinet in the distribution cabinet group can be completed. When the number of distribution cabinets to be installed is more or less, the number of connection blocks that can be installed on the cabinet group base can be changed by changing the number of base groups, so that all the distribution cabinets that need to be installed on the bottom layer can be stably installed on the cabinet group base. And in the prior art, the patent with the publication number "CN119209229A" and the patent name "A Distribution Cabinet Dehumidification Component and a Distribution Cabinet" discloses that a plurality of dehumidification fans are evenly distributed at equal intervals along the length direction on the two vertical side walls of the horizontal cylinder. A sealing frame is arranged between the dehumidification fans and the horizontal cylinder. Through the sealing frame, the gap between the dehumidification fans and the horizontal cylinder can be compensated to prevent air from being discharged from the gap and affecting the blowing effect of the dehumidification fans. When the dehumidification fans blow air into the distribution cabinet, the air in the horizontal cylinder is pumped out, so that a negative pressure is generated inside the horizontal cylinder, and the air inside the distribution cabinet enters the horizontal cylinder after passing through the air inlet hopper and the through holes. At the same time, the electric heating sheet is started, and the electric heating sheet heats the air in the horizontal cylinder to facilitate drying the moisture in the air. Then, when the dehumidification fans blow out the hot air, the moisture in the air inside the distribution cabinet can be further heated and dried.

[0003] Although the intelligent power distribution cabinet group in the above-mentioned prior art uses multiple dehumidifying fans in cooperation with the horizontal cylinder to heat the air in the horizontal cylinder with an electric heating sheet to achieve the effects of dehumidification, moisture-proof and waterproof, the use of multiple dehumidifying fans will consume a large amount of electric energy, resulting in the intelligent power distribution cabinet group not being able to save electricity and energy well when used in the intelligent power grid. Moreover, the hot air is blown out by the dehumidifying fan to heat and dry the moisture in the air inside the power distribution cabinet. Although the effects of dehumidification and moisture-proof are achieved in this way, the air temperature inside the power distribution cabinet will increase, which is not convenient for cooling the inside of the power distribution cabinet, and then affects the use of the intelligent power distribution cabinet group. Therefore, we propose an intelligent moisture-proof power distribution cabinet group to solve the problems raised above. Summary of the Invention

[0005] To achieve the above purpose, the present invention provides the following technical solutions: An intelligent moisture-proof power distribution cabinet group includes a cabinet body shell and a sealing door body installed on its front side. A condensation dehumidifier is installed on the front side of the cabinet body shell below the sealing door body. An exhaust pipe penetrates and is fixed on the rear side of the cabinet body shell, and an intermittent exhaust mechanism is connected inside the exhaust pipe. A fixing plate is fixed inside the cabinet body shell, and an installation guide rail frame for installing electrical components is installed above the fixing plate. A multi-stage moisture absorption component is connected inside the cabinet body shell below the fixing plate. A diversion pipe for transporting air for ventilation and heat dissipation is installed through the interior of the rear side of the fixing plate. A temperature sensor is fixed on the upper inner wall of the cabinet body shell.

[0006] Preferably, a drain pipe is fixed below the condensation dehumidifier, and an air delivery pipe installed at the rear of the condensation dehumidifier penetrates and is inserted into the cabinet body shell. A dust-proof filter plate is installed on the front side of the condensation dehumidifier.

[0007] Preferably, the multi-stage moisture absorption component includes a sealing plate that is hermetically and slidably installed inside the cabinet body shell below the fixing plate. A molecular sieve component is fixed on the front side of the sealing plate. Partition baffles are equidistantly and fixedly penetrated inside the molecular sieve component. The outer sides of the sealing plate, the partition baffles and the molecular sieve component are all in contact with the inner wall of the cabinet body shell. Adjacent partition baffles are respectively provided with through grooves for air circulation inside the upper part and the lower part.

[0008] Preferably, the lower end of the diversion pipe is communicated with the space inside the cabinet shell below the fixed plate. The diversion pipe is arranged in a "7" - shaped structure. The upper end of the diversion pipe is connected to the ventilation and cooling pipe through a hose. A row of nozzles is installed on the inner side wall of the ventilation and cooling pipe.

[0009] Preferably, a single - rotation reciprocating lead screw is installed in a groove inside the fixed plate. A "U" - shaped control frame is threadedly connected through the outside of the single - rotation reciprocating lead screw. The rear sides of the left and right sides of the control frame are both connected to the ventilation and cooling pipe.

[0010] Preferably, the air delivery pipe is arranged below the fixed plate and is used to deliver the air dehumidified by the condensation dehumidifier to the space below the fixed plate for further dehumidification by a multi - stage moisture absorption component.

[0011] Preferably, the intermittent exhaust mechanism includes a sealing piston assembly that fits and slides on the inner wall of the exhaust pipe. An exhaust hole is opened on the outside of the exhaust pipe. The sealing piston assembly is used to cover and seal the exhaust hole.

[0012] Preferably, the front end of the sealing piston assembly is connected to a "U" - shaped control frame. The front end of the exhaust pipe is connected to the rear side of the control frame through a return spring. The return spring is sleeved on the outside of the front end of the sealing piston assembly. Ventilation and cooling pipes are arranged in front of the left and right sides of the control frame. The ventilation and cooling pipes form a front - and - back sliding structure through the control frame.

[0013] Preferably, an aggregation sleeve is hermetically sleeved on the outside of the exhaust pipe. The aggregation sleeve is located outside the exhaust hole. A circulation pipe is installed through the outside of the aggregation sleeve. The other end of the circulation pipe penetrates into the inside of the cabinet shell and is inserted into the condensation dehumidifier.

[0014] Preferably, a detection frame with a mesh - shaped interior is installed inside the front side of the cabinet shell through a manual telescopic rod. A connecting spring is nested on the outside of the manual telescopic rod. A pressure sensor is installed on the cabinet shell directly below the detection frame. Silica gel particles for moisture absorption are placed inside the detection frame with a "hui" - shaped structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This intelligent moisture - proof power distribution cabinet group can further remove moisture in the air, so it can prevent moisture from entering the inside of the power distribution cabinet group. Thus, the moisture - proof and waterproof performance of the entire power distribution cabinet group can be improved, and the power consumption can be reduced, enabling the intelligent power distribution cabinet group to save electricity and energy well when used in the intelligent power grid. The specific content is as follows: The multi-stage moisture absorption component composed of a molecular sieve component and a partition baffle enables the air to flow in a wavy curved path. This not only extends the flow distance of the air from the outside to the inside but also changes the air flow direction multiple times, allowing the air to come into contact with the molecular sieve component multiple times, increasing the chance of intercepting the moisture in the air. Subsequently, it is convenient for the molecular sieve component to conduct multiple moisture absorption treatments on the air, thereby further removing the moisture in the air. Therefore, it can prevent moisture from entering the interior of the power distribution cabinet group, thus improving the moisture-proof and waterproof performance of the entire power distribution cabinet group; Meanwhile, by using the molecular sieve component, the power consumption can be reduced, enabling the intelligent power distribution cabinet group to save electricity and energy well when used in the intelligent power grid.

[0016] The air after removing moisture can be sprayed to various positions inside the cabinet shell through a reciprocating ventilation and cooling pipe, so as to facilitate the heat dissipation and cooling of the heat inside the cabinet shell; By intermittently pushing the control frame through the ventilation and cooling pipe, the control frame can drive the sealing piston component to move intermittently. As a result, the air inside the cabinet shell can be intermittently discharged through the exhaust pipe and exhaust holes. Therefore, through a reasonable ventilation structure design, not only can external moisture be prevented from entering the cabinet shell, but also the air circulation inside the cabinet shell can be ensured, avoiding the excessive heat inside the cabinet shell from affecting the use; Meanwhile, through the setting of the circulation pipeline, the gas discharged from the exhaust pipe can be transported to the condensation dehumidifier, facilitating the recycling of the gas.

[0017] The detection frame is filled with silica gel particles. Therefore, when the silica gel particles absorb moisture and increase in weight, the detection frame applies pressure to the pressure sensor, enabling the detection of whether the sealing strip of the sealing door body is damaged, facilitating the timely replacement of the damaged sealing strip.

The specific structure refers to the attached Figures 1-9As shown in the figure, it includes a cabinet shell 1 and a sealed door body 2 installed on its front side.

A dust-proof filter plate 4 is installed on the front side of the condensing dehumidifier 3. The multi-stage moisture absorption component includes a sealing plate 11 that is hermetically and slidably installed inside the cabinet shell 1 below the fixing plate 14. A molecular sieve component 12 is fixed on the front side of the sealing plate 11. Partition baffles 13 are fixedly penetrated at equal intervals inside the molecular sieve component 12. The outer sides of the sealing plate 11, the partition baffles 13, and the molecular sieve component 12 are all in contact with the inner wall of the cabinet shell 1. Adjacent partition baffles 13 are respectively provided with through slots 131 for air circulation in the upper and lower interiors.

[0022] The lower end of the diversion pipe 18 is communicated with the space inside the cabinet shell 1 below the fixing plate 14. The diversion pipe 18 is arranged in a "7" - shaped structure. The upper end of the diversion pipe 18 is connected to the ventilation and cooling pipe 17 through a hose. A row of nozzles is installed on the inner side wall of the ventilation and cooling pipe 17. A single - rotation reciprocating lead screw 15 is installed in a groove inside the fixing plate 14. A "U" - shaped control frame 16 is threadedly connected through the outside of the single - rotation reciprocating lead screw 15. The rear sides of the left and right sides of the control frame 16 are both connected to the ventilation and cooling pipe 17. The air delivery pipe 302 is arranged below the fixing plate 14 and is used to convey the air dehumidified by the condensing dehumidifier 3 to the lower part of the fixing plate 14 for re - dehumidification by the multi - stage moisture absorption component. The intermittent exhaust mechanism includes a sealing piston component 20 that is slidably connected in contact with the inner wall of the exhaust pipe 6. An exhaust hole 61 is opened on the outside of the exhaust pipe 6. The sealing piston component 20 is used to cover and seal the exhaust hole 61. The front end of the sealing piston component 20 is connected to a "U" - shaped control frame 10. The front end of the exhaust pipe 6 is connected to the rear side of the control frame 10 through a return spring 21. The return spring 21 is sleeved on the outside of the front end of the sealing piston component 20. The ventilation and cooling pipes 17 are arranged in front of the left and right sides of the control frame 10. The ventilation and cooling pipes 17 form a front - and - rear sliding structure through the control frame 10.

[0023] First, move the entire intelligent moisture-proof power distribution cabinet group to the working area. Then, the intelligent moisture-proof power distribution cabinet group can collect data such as voltage, current, and power, providing real-time operation information for the smart grid. When the temperature sensor 9 detects a relatively high temperature inside the cabinet body shell 1 and ventilation and heat dissipation are required, the condensation dehumidifier 3 is started simultaneously. The fan inside the condensation dehumidifier 3 rotates, sucking in outside air into the condensation dehumidifier 3. At this time, the air first passes through the dust-proof filter plate 4 for dust filtration and then enters the condensation dehumidifier 3. Then, the moisture in the air condenses into water droplets and is discharged through the drain pipe 301. The dehumidified air enters the cabinet body shell 1 below the fixing plate 14 through the air delivery 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 groove 131 in sequence. Therefore, the air flows in a wavy curved path, which not only extends the flow distance of the air from the outside to the inside but also changes the air flow direction multiple times, enabling the air to come into contact with the molecular sieve assembly 12 multiple times, increasing the chance of intercepting the moisture in the air. Subsequently, it is convenient for the molecular sieve assembly 12 to perform multiple moisture absorption treatments on the air, thereby further removing the moisture in the air. At the same time, by using the molecular sieve assembly 12, the power consumption can be reduced, enabling the intelligent power distribution cabinet group to save electricity and energy well when used in the smart grid. Then, the air after removing moisture enters the ventilation and cooling pipe 17 through the diversion pipe 18 and the hose. The air is sprayed into the cabinet body shell 1 through the spray pipe inside the ventilation and cooling pipe 17. At the same time, the motor inside the fixing plate 14 is started. The motor drives the single-thread reciprocating lead screw 15 to rotate. When the single-thread reciprocating lead screw 15 rotates, it drives the control frame 16 connected by external threads to move back and forth. Then, the control frame 16 drives the ventilation and cooling pipe 17 to move back and forth. Therefore, the ventilation and cooling pipe 17 evenly sprays the dehumidified air into the cabinet body shell 1 to facilitate heat dissipation and cooling of the heat around the installation guide rail frame 7.

[0024] When the ventilation and cooling pipe 17 moves backward and contacts the front side of the control frame 10, if the ventilation and cooling pipe 17 continues to move backward, it will push the control frame 10 backward. Then, the control frame 10 drives the seal piston assembly 20 to move backward. At this time, the return spring 21 is compressed and stores energy. When the seal piston assembly 20 moves backward, it separates from the corresponding exhaust hole 61. At this time, the air inside the cabinet body shell 1 is discharged outward through the exhaust hole 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 seal piston assembly 20 to move forward and reset, so that the seal piston assembly 20 seals the exhaust hole 61. By operating in this way repeatedly, intermittent ventilation and heat dissipation can be carried out inside the cabinet body shell 1. Through a reasonably designed ventilation structure, not only can external moisture be prevented from entering the cabinet body shell 1, but also the air circulation inside the cabinet body shell 1 can be ensured, avoiding excessive heat inside the cabinet body shell 1 from affecting the use.

[0025] In the later stage, the sealing plate 11 can be pulled to pull out the molecular sieve assembly 12 from the cabinet housing 1 for replacement or regeneration by heating or drying in the sun, so that the molecular sieve assembly 12 can be reused, which is economical and environmentally friendly.

[0026] Embodiment 2: In the intelligent moisture-proof power distribution cabinet group in this embodiment, on the basis of Embodiment 1, the gas discharged from the exhaust pipe 6 can enter the condensation dehumidifier 3 again for condensation dehumidification, so as to ventilate and recycle the discharged gas again. For the specific structure, refer to the attached Figures 1-4 and the attached Figures 7-10 As shown, an aggregation sleeve 19 is hermetically sleeved outside the exhaust pipe 6. The aggregation sleeve 19 is located outside the exhaust hole 61. A circulation pipe 5 is installed through the outside of the aggregation sleeve 19. The other end of the circulation pipe 5 penetrates into the interior of the cabinet housing 1 and is inserted into the condensation dehumidifier 3. When the air in the cabinet housing 1 is discharged outward through the exhaust hole 61, the discharged air is collected through the aggregation sleeve 19 at this time, and then the air in the aggregation sleeve 19 enters the condensation 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 recycle the discharged air.

[0027] Embodiment 3: In the intelligent moisture-proof power distribution cabinet group in this embodiment, on the basis of Embodiment 1, it is possible to detect whether the sealing strip inside the sealing door body 2 is damaged, so as to facilitate timely replacement of the damaged sealing strip. For the specific structure, refer to the attached Figure 4 and the attached Figure 11 As shown, a detection frame 8 with a mesh inside is installed inside the front side of the cabinet housing 1 through a manual telescopic rod 81. A connecting spring 82 is nested outside the manual telescopic rod 81. A pressure sensor 22 is installed on the cabinet housing 1 directly below the detection frame 8. Silica gel particles for moisture absorption are placed inside the detection frame 8 with a "return" shape structure.

[0028] When it is detected that the sealing strip inside the sealing door body 2 is damaged, at this time, the sealing performance of the sealing door body 2 is poor, and then the outside moisture will enter the cabinet housing 1. Then the moisture first passes through the detection frame 8 with a mesh inside. At this time, the silica gel particles in the detection frame 8 increase in weight after absorbing moisture, and the detection frame 8 will automatically move downward to squeeze the manual telescopic rod 81. At the same time, when the detection frame 8 moves downward to a certain position, it will exert a certain pressure on the pressure sensor 22. At this time, the pressure sensor 22 transmits this signal to the central processing module, and then the central processing module controls the alarm installed on the cabinet housing 1 to emit an alarm sound, so as to timely remind the staff to replace the sealing strip, thus completing a series of work.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
