Technical Field
[0001] The present invention relates to the technical field of distribution network cabinets, and specifically to an automatic dehumidification and drying system for distribution network cabinets. Background Art
[0002] As a key device for distributing and controlling electric energy, distribution network cabinets are widely used in various fields such as urban power grids, industrial enterprises, and residential communities. Their stable operation is crucial for ensuring the reliability and safety of power supply. However, during the actual operation of distribution network cabinets, they face severe challenges regarding humidity problems; Distribution network cabinets are usually installed outdoors or in places with complex environments, and are vulnerable to the invasion of rainwater, humid air, groundwater vapor, etc. For example, during the plum rain season in the south, the air humidity remains at a relatively high level for a long time, and a large amount of water vapor easily enters the interior through gaps, ventilation openings, and other parts of the cabinet. Excessive humidity will cause condensation inside the cabinet, and water droplets will adhere to the surface of electrical equipment, which may trigger short - circuit faults, resulting in equipment damage. At the same time, when in a high - humidity environment for a long time, the metal parts of electrical equipment will accelerate oxidation and corrosion, shortening the service life of the equipment and increasing the equipment maintenance and replacement costs; Traditional dehumidification methods for distribution network cabinets, such as installing ordinary desiccants, have limited moisture absorption capacity, require frequent replacement, have high maintenance costs and unstable effects; some simple ventilation devices used cannot effectively prevent external humid air from entering during humid weather, have poor dehumidification effects, and cannot dehumidify the humid air already existing inside the distribution network cabinet. Summary of the Invention
[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: An automatic dehumidification and drying system for distribution network cabinets, comprising: A dehumidification mechanism, and an elbow pipe two fixedly connected to the air inlet end of the dehumidification mechanism. The dehumidification mechanism is used to separate water vapor from the humid air inside the distribution network cabinet. A drying mechanism is installed at the air outlet end of the dehumidification mechanism. The drying mechanism performs a drying process on the preliminarily dehumidified air. A control panel is fixedly installed on the surface of the drying mechanism. A elbow pipe three is fixedly connected to the bottom of the drying mechanism. A guiding mechanism is fixedly installed at the air outlet end of the elbow pipe three. The guiding mechanism guides the dried air to flow in a specific direction; An air inlet mechanism, which is installed at the air inlet end of the dehumidification mechanism through the elbow pipe two. The air inlet mechanism detects the air humidity inside the distribution network cabinet and introduces the humid air into the system; An air outlet mechanism, which is installed at the air outlet end of the guiding mechanism through the elbow pipe four. The air outlet mechanism controls the discharge direction and flow rate of the dried air; Among them, the dehumidification mechanism includes a first ventilation pipe. The air outlet end of the first ventilation pipe is fixedly connected with a first elbow pipe. An outlet water pipe is fixedly installed on the inner bent side of the outer surface of the first elbow pipe. The outlet water pipe is used to discharge the separated water. An air inlet groove is formed in the inner wall of the first ventilation pipe, and a first air guiding groove is formed inside the air inlet groove. The air inlet groove and the first air guiding groove are used to guide the dehumidified air. A water guiding piece is fixedly installed at the inner wall of the first elbow pipe. The water guiding piece guides the separated water to the outlet water pipe to ensure the smooth discharge of moisture.
[0004] Preferably, the air inlet groove is specifically an annular groove. The air inlet groove is perpendicular to the axis of the first ventilation pipe, and the air inlet grooves are evenly distributed on the inner wall of the first ventilation pipe. The first air guiding groove is arranged perpendicular to the air inlet groove. The first air guiding groove penetrates the air inlet groove, and the first air guiding grooves are evenly distributed along the axis of the first ventilation pipe. A separating member is installed inside the first elbow pipe, and the separating member separates water vapor from the humid air.
[0005] Preferably, the separating member includes a first motor. The first motor is fixedly installed on the inner wall of the first elbow pipe through a bracket. The output end of the first motor is fixedly connected with a separating barrel. A fixing rod is fixedly installed in the middle of the inside of the separating barrel. A spiral blade is fixedly installed on the surface of the fixing rod. Air outlet holes are formed on the surface of the separating barrel. The bottom end of the separating barrel is fixedly connected with a water guide pipe. The water guide pipe is arranged above the water guiding piece. When rotating driven by the first motor, the humid air will be affected by centrifugal force. Since the density of water vapor is less than that of air, under the action of centrifugal force, the water vapor will move towards the central area of the barrel, while the relatively dry air will be thrown to the outside of the barrel. The internal fixing rod and spiral blade assist in separating water vapor. The air outlet holes on the surface are used to discharge the separated air, and the water guide pipe is used to guide out the separated water.
[0006] Preferably, the air outlet holes are specifically in a flared structure, and the aperture of the end of the air outlet hole close to the inner wall of the separating barrel is smaller, and the aperture gradually increases towards the end far from the inner wall of the separating barrel. This design is beneficial to the discharge of the separated air. The air outlet holes are arranged inside the air inlet groove.
[0007] Preferably, the air inlet mechanism includes an air inlet cylinder. The diameter of the air inlet cylinder gradually decreases from the air inlet end to the air outlet end. The air inlet cylinder guides the humid air to enter. Its tapered structure helps to accelerate the air flow rate. A blower is installed inside the air inlet cylinder. The blower promotes the air to flow towards the dehumidification mechanism. A humidity sensor is fixedly installed at the air inlet end of the air inlet cylinder to detect the air humidity in the distribution network cabinet in real time. The data of the humidity sensor is received through the control panel, and the operation of equipment such as the blower and the first motor is controlled according to the preset humidity value to realize the automatic operation of the system.
[0008] Preferably, the drying mechanism includes a second ventilation pipe. A sealing cover is rotatably installed on the surface of the second ventilation pipe. Filters are fixedly installed at both ends of the inner wall of the second ventilation pipe. A drying bag is detachably installed inside the second ventilation pipe. The sealing cover facilitates the replacement of the internal drying bag. The drying bag uses a desiccant to adsorb residual water vapor in the air to further dry the air.
[0009] Preferably, the guiding mechanism includes a third ventilation pipe. An air guide pipe is fixedly installed inside the third ventilation pipe. The air guide pipe guides the flow of dry air. An air guide groove II is formed in the inner wall of the air guide pipe.
[0010] Preferably, the air guide pipe is shaped with a thinner middle part and thicker ends, and the diameter of the middle section of the air guide pipe gradually increases towards both ends. This design enables the air flow to accelerate at the air inlet end and the air flow to be evenly distributed at the air outlet end when the air passes through the air guide pipe. The air guide groove II further makes the air flow concentrated and orderly towards the air outlet mechanism.
[0011] Preferably, the air outlet mechanism includes a fourth ventilation pipe. A fixing plate is fixedly installed on the surface of the fourth ventilation pipe. A second motor is fixedly installed on the surface of the fixing plate through a bracket. A rotating rod is rotatably installed at the air outlet end of the fourth ventilation pipe. The rotating rod penetrates through the fourth ventilation pipe and extends to both sides thereof. Pulleys are fixedly installed at both ends of the rotating rod. A belt is drivingly installed on the outer surface of the pulley. The output end of the second motor is fixedly connected to the axis of the pulley. Wind blocking pieces are fixedly installed on the surface of the rotating rod.
[0012] Preferably, the rotating rods are evenly distributed at the air outlet end of the fourth ventilation pipe. The wind blocking pieces are made of rubber material. The air outlet direction and flow rate are controlled by changing the angle of the wind blocking pieces. The rubber material has a certain flexibility, which can reduce the noise during air outlet. At the same time, the rubber material can better fit the inner wall of the fourth ventilation pipe, making the air outlet adjustment effect better.
[0013] The present invention provides an automatic dehumidification and drying system for a distribution network cabinet, which has the following beneficial effects: First, in the automatic dehumidification and drying system for the distribution network cabinet, through the settings of the humidity sensor and the control panel, the humidity sensor is installed at the air inlet end of the air inlet cylinder to detect the air humidity inside the distribution network cabinet in real time and transmit the data to the control panel. The control panel controls the operation of equipment such as the blower, the first motor, and the second motor according to the preset humidity value and the received data, realizing automatic control. Accurately controlling the working states of each device according to the humidity situation can avoid excessive dehumidification or insufficient drying, effectively improving the dehumidification and drying effect. At the same time, it saves energy and reduces unnecessary equipment operation losses.
[0014] II. The automatic dehumidification and drying system of the distribution cabinet uses a separating component. When air enters the separating component and the first motor drives the separating barrel to rotate at high speed, after the humid air enters the high-speed rotating separating barrel, it will be affected by the centrifugal force. Since the density of water vapor is less than that of air, under the action of the centrifugal force, the water vapor will move towards the central area of the barrel, while the relatively dry air will be thrown towards the outer side of the barrel. The spiral blades can guide the air to flow along a spiral path, extending the residence time of the air in the barrel and allowing more time for the water vapor to be separated. The separated air is then discharged through the flared air outlet holes on the surface of the separating barrel. The separating component efficiently separates the water vapor from the humid air, improving the dryness of the air and reducing the risk of equipment failures caused by moisture in the distribution cabinet.
[0015] III. The automatic dehumidification and drying system of the distribution cabinet uses a dehumidifying mechanism. After the air separated by the separating component is discharged through the flared air outlet holes on the surface of the separating barrel, the air enters the air inlet groove and is guided by the first air guide groove into the first elbow pipe. When the first motor is turned off, due to the action of gravity, the separated water droplets flow to the bottom water guide pipe, then through the water guide pipe to the water guide plate, and finally are guided by the water guide plate to the water outlet pipe to be discharged from the system, preventing the separated water vapor from re-entering the distribution cabinet.
[0016] IV. The automatic dehumidification and drying system of the distribution cabinet uses a drying mechanism. The dehumidified air enters the second ventilation pipe of the drying mechanism from the air outlet end of the dehumidifying mechanism. The desiccant in the drying bag adsorbs the residual water vapor in the air, achieving deep drying of the air. The filter screens at both ends of the inner wall of the second ventilation pipe prevent impurities in the drying bag from mixing into the air. If the drying bag is saturated with adsorption, the second ventilation pipe can be opened by rotating the sealing cover for replacement. Since the water vapor in the dehumidified air has been greatly reduced, the drying mechanism further dries it, improving the drying effect of the system.
[0017] V. The automatic dehumidification and drying system of the distribution cabinet uses an air outlet mechanism. The second motor drives the pulleys at both ends of the rotating rod to rotate through a belt, causing the rotating rod to rotate. The rubber windshields on the surface of the rotating rod change angles accordingly. The air outlet mechanism can flexibly control the discharge direction and flow rate of the dry air, enabling the dry air to be accurately delivered to the required parts inside the distribution cabinet, improving the pertinence and effect of dehumidification and drying, and effectively improving the humidity conditions in different areas of the cabinet.

The guiding mechanism 4 guides the dried air to flow in a specific direction; The air inlet mechanism 1 is installed at the air inlet end of the dehumidification mechanism 2 through the second elbow 6. The air inlet mechanism 1 detects the air humidity in the distribution network cabinet and introduces the humid air into the system. The air inlet mechanism 1 includes an air inlet cylinder 11. The diameter of the air inlet cylinder 11 gradually decreases from the air inlet end to the air outlet end. The air inlet cylinder 11 guides the humid air to enter, and its tapered structure helps to accelerate the air flow rate. A blower 12 is installed inside the air inlet cylinder 11, and the blower 12 promotes the air to flow towards the dehumidification mechanism 2. A humidity sensor 13 is fixedly installed at the air inlet end of the air inlet cylinder 11 to detect the air humidity in the distribution network cabinet in real time. The data of the humidity sensor 13 is received through the control panel 9, and the operation of the equipment is controlled according to the preset humidity value to realize the automatic operation of the system. The air outlet mechanism 5 is installed at the air outlet end of the guiding mechanism 4 through the fourth elbow 8. The air outlet mechanism 5 controls the discharge direction and flow rate of the dry air. The dehumidification mechanism 2 includes a first ventilation pipe 21. The air outlet end of the first ventilation pipe 21 is fixedly connected to a first elbow 22. A water outlet pipe 23 is fixedly installed on the inner bent side of the outer surface of the first elbow 22. The water outlet pipe 23 is used to discharge the separated water. An air inlet groove 25 is formed in the inner wall of the first ventilation pipe 21, and a first air guiding groove 26 is formed inside the air inlet groove 25. The air inlet groove 25 and the first air guiding groove 26 are used to guide the dehumidified air. A water guiding piece 27 is fixedly installed at the inner wall of the first elbow 22, and the water guiding piece 27 guides the separated water to the water outlet pipe 23 to ensure the smooth discharge of the water. The air inlet groove 25 is specifically an annular groove. The air inlet groove 25 is perpendicular to the axis of the first ventilation pipe 21, and the air inlet groove 25 is evenly distributed on the inner wall of the first ventilation pipe 21. The first air guiding groove 26 is perpendicular to the air inlet groove 25. The first air guiding groove 26 penetrates through the air inlet groove 25, and the first air guiding groove 26 is evenly distributed along the axis of the first ventilation pipe 21. A separating member 24 is installed inside the first elbow 22, and the separating member 24 separates the water vapor from the humid air.
[0022] Second embodiment, on the basis of the first embodiment, please refer to Figures 6 to 8As shown, the separating member 24 includes a first motor 241. The first motor 241 is fixedly installed on the inner wall of the first elbow pipe 22 through a bracket. The output end of the first motor 241 is fixedly connected to a separating barrel 242. A fixing rod 244 is fixedly installed in the middle of the separating barrel 242. A spiral blade 245 is fixedly installed on the surface of the fixing rod 244. Air outlet holes 243 are formed on the surface of the separating barrel 242. A water guide pipe 246 is fixedly connected to the bottom end of the separating barrel 242. The water guide pipe 246 is arranged above the water guide piece 27. Driven by the first motor 241 to rotate, the humid air will be affected by the centrifugal force. Since the density of water vapor is less than that of air, under the action of the centrifugal force, the water vapor will move towards the central area of the barrel, while the relatively dry air will be thrown towards the outside of the barrel. The internal fixing rod 244 and spiral blade 245 assist in separating the water vapor. The air outlet holes 243 on the surface are used to discharge the separated air, and the water guide pipe 246 is used to discharge the separated water; The air outlet holes 243 are specifically of a flared structure, and the aperture of the end of the air outlet hole 243 close to the inner wall of the separating barrel 242 is smaller, and the aperture gradually increases towards the end far from the inner wall of the separating barrel 242. This design is conducive to the discharge of the separated air. The air outlet holes 243 are arranged inside the air inlet groove 25; The drying mechanism 3 includes a second ventilation pipe 31. A sealing cover 32 is rotatably installed on the surface of the second ventilation pipe 31. Filter meshes 33 are fixedly installed at both ends of the inner wall of the second ventilation pipe 31. A drying bag 34 is detachably installed inside the second ventilation pipe 31. The sealing cover 32 facilitates the replacement of the internal drying bag 34. The drying bag 34 adsorbs the residual water vapor in the air with a desiccant to further dry the air.
[0023] For the third embodiment, on the basis of the first and second embodiments, please refer to Figures 9 to 10 As shown, the guiding mechanism 4 includes a third ventilation pipe 41. An air guide pipe 42 is fixedly installed inside the third ventilation pipe 41. The air guide pipe 42 guides the flow of the dry air. Air guide grooves 43 are formed on the inner wall of the air guide pipe 42; The air guide pipe 42 is arranged in a shape that is thin in the middle and thick at both ends, and the diameter of the middle section of the air guide pipe 42 gradually increases towards both ends. This design enables the air flow to accelerate at the air inlet end and makes the air flow evenly distributed at the air outlet end when passing through the air guide pipe 42. The air guide grooves 43 further make the air flow concentrated and orderly towards the air outlet mechanism 5; The air outlet mechanism 5 includes a fourth ventilation pipe 51. A fixing plate 52 is fixedly installed on the surface of the fourth ventilation pipe 51. A second motor 53 is fixedly installed on the surface of the fixing plate 52 through a bracket. A rotating rod 56 is rotatably installed at the air outlet end of the fourth ventilation pipe 51. The rotating rod 56 penetrates through the fourth ventilation pipe 51 and extends to both sides thereof. Pulley wheels 54 are fixedly installed at both ends of the rotating rod 56. A belt 55 is drivingly installed on the outer surface of the pulley wheels 54. The output end of the second motor 53 is fixedly connected to the axis of the pulley wheel 54. Wind shielding pieces 57 are fixedly installed on the surface of the rotating rod 56; The rotating rods 56 are evenly distributed at the air outlet end of the ventilation pipe four 51. The wind deflector 57 is made of rubber material. By changing the angle of the wind deflector 57, the air outlet direction and flow rate can be controlled. The rubber material has a certain flexibility, which can reduce the noise during air outlet. At the same time, the rubber material can better fit the inner wall of the ventilation pipe four 51, making the air outlet adjustment effect better.
[0024] During use, the outside air first enters the air inlet cylinder 11 of the air inlet mechanism 1. The diameter of the air inlet cylinder 11 gradually decreases from the air inlet end to the air outlet end. This structure can accelerate the air flow rate. The humidity sensor 13 at the air inlet end of the air inlet cylinder 11 real-time detects the air humidity in the distribution box cabinet and transmits the humidity data to the control panel 9. The blower 12 starts to provide power for the air flow, so that the air in the distribution box cabinet is conveyed to the dehumidification mechanism 2 through the elbow two 6. The air enters the separator 24. The motor one 241 is fixed on the inner wall of the elbow one 22 through a bracket, and its output end drives the separation barrel 242 to rotate at a high speed. After the humid air enters the high-speed rotating separation barrel 242, it will be affected by the centrifugal force. Since the density of water vapor is less than that of air, under the action of the centrifugal force, the water vapor will move towards the central area of the barrel, while the relatively dry air will be thrown to the outside of the barrel. The spiral blade 245 can guide the air to flow along a spiral path, extending the residence time of the air in the barrel, enabling the water vapor to have more sufficient time for separation. At the same time, the spiral blade 245 will stir the air during rotation, further promoting the separation of water vapor from the air. The separated air is discharged through the flared air outlet holes 243 on the surface of the separation barrel 242. The air enters the air inlet groove 25 and is guided by the air guide groove one 26 to enter the elbow one 22. When the motor one 241 is turned off, due to the action of gravity, the separated water droplets flow to the bottom water guide pipe 246, then flow through the water guide pipe 246 to the water guide piece 27, and finally are guided by the water guide piece 27 to the water outlet pipe 23 to be discharged from the system. The dehumidified air enters the ventilation pipe two 31 of the drying mechanism 3 from the air outlet end of the dehumidification mechanism 2. The desiccant in the drying bag 34 adsorbs the residual water vapor in the air, realizing the deep drying of the air. The filter screens 33 at both ends of the inner wall of the ventilation pipe two 31 prevent the impurities in the drying bag 34 from mixing into the air. If the drying bag 34 is saturated with adsorption, the ventilation pipe two 31 can be opened by rotating the sealing cover 32 for replacement. The dried air enters the ventilation pipe three 41 of the guiding mechanism 4 from the elbow three 7. The air guide pipe 42 fixedly installed inside the ventilation pipe three 41 is in the shape of being thin in the middle and thick at both ends, and the diameter of the middle section gradually increases towards both ends. When the air passes through the air guide pipe 42, the air flow accelerates at the air inlet end, and the air flow is evenly distributed at the air outlet end. The air guide groove two 43 opened on the inner wall of the air guide pipe 42 further accurately guides the air flow direction, enabling the air to flow towards the air outlet mechanism 5 concentratedly and orderly. The air guided by the guiding mechanism 4 enters the ventilation pipe four 51 of the air outlet mechanism 5. The second motor 53 is started. The output end of the second motor 53 drives the pulley 54 to rotate. Through the transmission of the belt 55, the pulleys 54 at both ends of the rotating rod 56 rotate synchronously, thereby driving the rotating rod 56 to rotate. The rubber windshields 57 fixed on the surface of the rotating rod 56 change their angles as the rotating rod 56 rotates. By adjusting the angles of the windshields 57, the discharge direction and flow rate of the dry air can be controlled, so that the dry air can be more accurately and effectively conveyed to the parts in the distribution network cabinet that need dehumidification and drying.
