Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinets, and in particular to an electrical cabinet that is integrated with moisture-proof, dust-proof and temperature control. Background Art

[0002] In industrial production and power equipment operation, electrical cabinets are critical equipment, housing numerous precision electronic components and electrical devices. These devices have stringent requirements for the temperature, humidity, and air cleanliness of their operating environment. A suitable temperature and humidity environment can effectively prevent performance degradation, short circuits, and even damage caused by overheating or moisture. A clean air environment can reduce the adhesion of dust and other impurities to equipment circuit boards and heat dissipation components, thereby extending equipment life and ensuring stable system operation.

[0003] Traditional electrical cabinets often face numerous limitations when it comes to meeting environmental challenges. For dust control, fixed filters are typically used to filter the air entering the cabinet. However, these filters are easily clogged by dust, hindering airflow and affecting heat dissipation efficiency. Clogged filters also require frequent manual cleaning, increasing maintenance costs and workload. Furthermore, fixed filters have limited dust filtering effectiveness and are unable to completely remove even tiny particles from the air. Some dust may still enter the cabinet, posing a potential threat to equipment.

[0004] Traditional electrical cabinets lack effective active dehumidification measures. When ambient humidity is high, moist air easily intrudes into the cabinet, forming condensation on the equipment surface, causing short circuits and insulation degradation, seriously impacting safe operation. While some cabinets are equipped with simple ventilation and heat dissipation devices, these cannot effectively treat moist air and fail to meet the equipment's low-humidity requirements.

[0005] When it comes to temperature control, traditional electrical cabinets rely on natural cooling or a single fan. This cooling effect is affected by a variety of factors, including ambient temperature and air circulation, making it difficult to precisely control the internal temperature. When equipment is operating at high loads, internal temperatures rise dramatically. Traditional cooling methods often fail to dissipate the heat quickly, causing the equipment to overheat and impacting its performance and lifespan.

[0006] Furthermore, traditional electrical cabinets often function independently of each other, lacking effective integration and coordinated control. The lack of information exchange and linkage between different functional modules prevents real-time adjustments to operating conditions based on environmental changes within the cabinet, making efficient and intelligent environmental control difficult.

[0007] In view of the above problems, it is of great practical significance to develop an integrated electrical cabinet that is moisture-proof, dust-proof and temperature-controlled. Summary of the Invention

[0008] The purpose of the present invention is to solve the above technical problems and to propose an integrated electrical cabinet with moisture-proof, dust-proof and temperature control.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0010] An integrated moisture-proof, dust-proof and temperature-controlled electrical cabinet includes the electrical cabinet, a cooling fan is installed at the lower end of one side of the electrical cabinet, a control box is installed on the side of the electrical cabinet facing away from the cooling fan, and a temperature and humidity sensor and a controller connected to the temperature and humidity sensor are installed in the electrical cabinet:

[0011] A dust filter drum is rotatably mounted in the control box, a baffle is rotatably mounted on the end of the dust filter drum, a plurality of steel balls are contained between the dust filter drum and the baffle, and when the dust filter drum rotates, the plurality of steel balls roll in the dust filter drum to form a three-dimensional and movable dust filter structure. When air flows upward through the control box, the dust filter drum performs primary dust filtration on the air, and the three-dimensional and movable dust filter structure performs secondary dust filtration on the air.

[0012] The control box is equipped with a refrigeration component that can cool the steel balls and is connected to the controller. When air flows onto the cooled and movable steel balls, the three-dimensional and movable steel balls exchange heat with the air and flow into the electrical cabinet through the circulation grooves; when humid air passes through the cooled steel balls, the humid air can be condensed, and the dehumidified air flows into the electrical cabinet through the circulation grooves.

[0013] Preferably, two guide plates are fixed to the inner wall of the control box. The guide plates are located on both sides of the dust filter cylinder and slide against each other. The guide plates divide the control box so that air can only flow through the dust filter cylinder.

[0014] Preferably, a motor connected to the controller is installed in the electrical cabinet, the output end of the motor is fixedly connected to the drive shaft, a short shaft is coaxially fixed on the dust filter cylinder, the short shaft passes through the electrical cabinet and is rotatably connected to it, a first bevel gear is installed on the drive shaft, a second bevel gear is fixed on the short shaft, and the first bevel gear is meshed with the second bevel gear.

[0015] Preferably, the refrigeration component includes a semiconductor refrigeration plate installed through the control box, the cooling end of the semiconductor refrigeration plate is installed with a cold air blower, the cold air blower is installed through the baffle, and the heating end of the semiconductor refrigeration plate is installed with a heat dissipation fan located outside the control box.

[0017] Preferably, it also includes an air supply mechanism for intermittently supplying air to the air storage box, the air supply mechanism includes a piston cylinder installed in the electrical cabinet, the piston cylinder is connected to the air storage box through an air outlet pipe, a movable piston is slidably connected in the piston cylinder, a connecting column is installed on the upper end of the movable piston, a reciprocating screw is rotatably installed on the upper end of the connecting column, a bracket is installed on the upper end of the piston cylinder, the reciprocating screw passes through the bracket and is cooperatively connected thereto, and the reciprocating screw is movably connected to the drive shaft.

[0018] Preferably, a rectangular groove is provided at the bottom of the driving shaft, a rectangular rod is slidably connected in the rectangular groove, and the rectangular rod is fixedly connected to the upper end of the reciprocating screw rod.

[0019] Preferably, an air inlet pipe is installed on the piston cylinder, an air inlet one-way valve is installed on the air inlet pipe, and an air outlet one-way valve is installed on the air outlet pipe.

[0020] Preferably, a plurality of air inlet holes are provided through the bottom of the control box, and the air inlet holes are located below the guide plate.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Significantly improved dust prevention effect: Primary dust filtration: The air entering the electrical cabinet is filtered through the rotating dust filter cylinder. The continuous rotation of the dust filter cylinder avoids the problem of fixed filters being easily clogged by dust, extends the service life of the dust filter cylinder, and reduces the frequency of manual cleaning and maintenance costs; Secondary dust filtration: The rolling steel balls in the dust filter cylinder form a three-dimensional and movable dust filter structure, which performs secondary dust filtration on the air, further improving the filtering effect of tiny particles in the air, reducing the amount of dust entering the electrical cabinet, and protecting the equipment from dust damage.

[0023] 2. Self-cleaning function: When the dust filter cylinder rotates, the rolling of the internal steel balls hits the dust filter cylinder, causing it to vibrate, thereby shaking off the dust filtered on the dust filter cylinder, realizing the self-cleaning of the dust filter cylinder and further improving the dust filtering efficiency.

[0024] 3. The moisture-proof effect is significantly enhanced: Active dehumidification: The steel balls are cooled by refrigeration components. When humid air passes through the refrigerated steel balls, the moisture in the air condenses into water droplets on the surface of the steel balls, thereby achieving effective dehumidification of the humid air, reducing the humidity inside the electrical cabinet, and avoiding problems such as circuit short circuit and degradation of insulation performance caused by the intrusion of humid air.

[0025] 4. Condensate treatment: As the steel balls continue to roll, the water condensed on the surface of the steel balls will quickly detach and eventually flow downward due to gravity. This not only avoids the impact of condensed water on the equipment, but also may produce a recoil effect on the dust filter cylinder, further improving the dust removal effect.

[0026] 5. The temperature control effect is precise and controllable: Active heat dissipation: The steel balls are cooled by refrigeration components, and the air is fully heat-exchanged when passing through the three-dimensional and mesh-structured steel balls. The cold air after heat exchange enters the electrical cabinet to replace the hot air, thus achieving effective heat dissipation inside the electrical cabinet.

[0027] 6. Integrated Design: This cabinet integrates dust and moisture protection with temperature control, and uses a controller to implement information exchange and linkage between functional modules. Efficient Collaboration: The operating status of each functional module is adjusted in real time based on changes in the cabinet's internal environment, achieving efficient and intelligent environmental control and improving the cabinet's overall performance and reliability.

[0028] 7. When the pressure in the air storage tank is greater than the threshold of the pressure relief valve, the pressure relief valve opens, and the high-pressure air is transported to the spray hole through the delivery pipe. The spray hole sprays out the high-pressure air and back-blows the dust filter net to clean it, thereby processing the dust in the dust filter net so that it can continue to filter dust.

[0029] In summary, the present invention has efficient dustproof, moisture-proof and temperature control functions, and the various functional modules can work together, automatically adjust the working mode according to changes in the internal environment of the electrical cabinet, provide a stable and suitable operating environment for the equipment inside the electrical cabinet, ensure the safe and reliable operation of the equipment, and at the same time reduce maintenance costs and increase the service life of the equipment.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] Reference Figures 1-9 A moisture-proof, dust-proof and temperature-controlled integrated electrical cabinet includes an electrical cabinet 1, a cooling fan 2 is installed at the lower end of one side of the electrical cabinet 1, a control box 5 is installed on the side of the electrical cabinet 1 facing away from the cooling fan 2, a temperature and humidity sensor 12 and a controller 13 connected to the temperature and humidity sensor 12 are installed in the electrical cabinet 1:

[0042] A dust filter cylinder 7 is rotatably installed in the control box 5. Two guide plates 9 are fixed to the inner wall of the control box 5. The guide plates 9 are located on both sides of the dust filter cylinder 7 and slide against each other. The guide plates 9 divide the control box 5 and also limit the two ends of the dust filter cylinder 7 so that air can only circulate through the dust filter cylinder 7. In this way, the air entering the electrical cabinet 1 can be fully treated.

[0043] A plurality of air inlet holes 15 are provided through the bottom of the control box 5 , and the air inlet holes 15 are located below the guide plate 9 .

[0044] The rotating dust filter cylinder 7 is further explained as follows: a motor 14 connected to the controller 13 is installed in the electrical cabinet 1, and the output end of the motor 14 is fixedly connected to the drive shaft 17. A short shaft 29 is coaxially fixed on the dust filter cylinder 7, and the short shaft 29 passes through the electrical cabinet 1 and is rotatably connected thereto. A first bevel gear 18 is installed on the drive shaft 17, and a second bevel gear 30 is fixed on the short shaft 29. The first bevel gear 18 is meshed with the second bevel gear 30.

[0045] The end of the dust filter cylinder 7 is rotatably mounted with a baffle 16, which can be mounted in the control box 5 through a connecting frame; the dust filter cylinder 7 comprises a stainless steel cylinder, and a dustproof net, such as a nylon dustproof net, is fixed to the outside of the stainless steel cylinder.

[0046] A plurality of steel balls 4 are contained between the dust filter net cylinder 7 and the baffle 16. When the dust filter net cylinder 7 rotates, the plurality of steel balls 4 roll inside the dust filter net cylinder 7 to form a three-dimensional and movable dust filter structure. When the air flows upward through the control box 5, the dust filter net cylinder 7 performs primary dust filtration on the air, and the three-dimensional and movable dust filter structure performs secondary dust filtration on the air. In this way, the air can be subjected to secondary filtration treatment.

[0047] The control box 5 is equipped with a refrigeration component 6 that can cool the steel balls 4 and is connected to the controller 13. The refrigeration component 6 is located above the guide plate 9. The refrigeration component 6 includes a semiconductor refrigeration plate 26 installed through the control box 5. The cooling end of the semiconductor refrigeration plate 26 is equipped with a cold air blower 28. The cold air blower 28 is installed through the baffle 16. The heating end of the semiconductor refrigeration plate 26 is equipped with a heat dissipation fan 27 located outside the control box 5 for dissipating heat from the semiconductor refrigeration plate 26 to ensure its stable operation.

[0048] When the air flows onto the cooled and movable steel balls 4, the three-dimensional and movable steel balls 4 exchange heat with the air and flow into the electrical cabinet 1 through the circulation grooves 3; when the humid air passes through the cooled steel balls 4, the humid air can be condensed, and the dehumidified air flows into the electrical cabinet 1 through the circulation grooves 3.

[0049] It also includes a back-blowing mechanism capable of back-blowing and cleaning the dust filter screen drum 7. The back-blowing mechanism includes an air storage box 11 installed in the control box 5. A delivery pipe 22 is installed at the upper end of the air storage box 11. A pressure relief valve 23 is installed on the delivery pipe 22. The delivery pipe 22 passes through the baffle 16 and extends into the dust filter screen drum 7. A plurality of spray holes 8 are provided at the bottom of the delivery pipe 22. The air ejected from the spray holes 8 can back-blow the dust filter screen drum 7.

[0050] It also includes an air supply mechanism for intermittently supplying air to the air storage box 11. The air supply mechanism includes a piston cylinder 10 installed in the electrical cabinet 1. The piston cylinder 10 is connected to the air storage box 11 through an air outlet pipe 31. An air outlet one-way valve 32 is installed on the air outlet pipe 31. The air outlet one-way valve 32 only allows air to flow through the piston cylinder 10 into the air outlet pipe 31; a movable piston 19 is slidably connected in the piston cylinder 10, and a connecting column 34 is installed on the upper end of the movable piston 19. A reciprocating screw 21 is rotatably installed on the upper end of the connecting column 34. A bracket 33 is installed on the upper end of the piston cylinder 10, and the reciprocating screw 21 passes through the bracket 33 and is connected thereto.

[0051] The reciprocating screw rod 21 is movably connected to the driving shaft 17 . A rectangular groove is provided at the bottom of the driving shaft 17 . A rectangular rod 20 is slidably connected in the rectangular groove. The rectangular rod 20 is fixedly connected to the upper end of the reciprocating screw rod 21 .

[0052] An air intake pipe 24 is installed on the piston cylinder 10 , and an air intake one-way valve 25 is installed on the air intake pipe 24 . The air intake one-way valve 25 only allows air to enter the piston cylinder 10 through the air intake pipe 24 .

[0053] When the present invention is used, the motor 14 drives the drive shaft 17 to rotate, which in turn drives the first bevel gear 18 to rotate. The rotation of the first bevel gear 18 drives the second bevel gear 30 to rotate, thereby realizing the rotation of the short shaft 29 and the dust filter cylinder 7;

[0054] The cooling fan 2 works to discharge the hot air in the electrical cabinet 1, and the external air flows upward through the air inlet 15 with the control box 5 as the flow channel. Due to the setting of the guide plate 9, the air can only flow upward through the dust filter mesh cylinder 7, and the air can be filtered at the first level through the dust filter mesh cylinder 7. Since the dust filter mesh cylinder 7 rotates continuously, the position of the air filtration is different, which will not cause the dust filter mesh cylinder 7 to be quickly blocked.

[0055] The rolling of the dust filter net cylinder 7 drives the steel balls 4 inside to roll, and the rolling of the steel balls 4 impacts the dust filter net cylinder 7 to cause it to vibrate, so that the dust filtered by the dust filter net cylinder 7 can be shaken off, thus realizing the self-cleaning of the dust filter net cylinder 7.

[0056] In addition, since the steel balls 4 roll in the dust filter mesh cylinder 7, the steel balls 4 form a three-dimensional mesh structure in the dust filter mesh cylinder 7. When dust that is not filtered by the dust filter mesh cylinder 7 enters the interior, the three-dimensional and mesh structured steel balls 4 also play a role in dust blocking and filtering, thereby achieving secondary filtration of the air (there is very little dust here).

[0057] When the temperature and humidity sensor 12 monitors that the humidity inside the electrical cabinet 1 is greater than the set threshold, the temperature and humidity sensor 12 transmits a signal to the controller 13. The controller 13 controls the refrigeration component 6 to be powered on and the cold air blower 28 can blow low-temperature air onto the rolling steel balls 4. Since the steel balls 4 roll, they can be cooled more effectively and evenly.

[0058] When the humid air passes through the dust filter cylinder 7 and hits the cooling steel balls 4, the steel balls roll and form a three-dimensional structure, which can effectively condense the humid air, thereby reducing the humidity of the air. The dehumidified air flows into the electrical cabinet 1 to replace the internal humid air, which can reduce the impact on internal equipment.

[0059] As the steel balls 4 continue to roll, the water condensed on the surface of the steel balls will quickly separate from the steel balls 4. Eventually, the water flows downward due to gravity, which can backwash the dust filter cylinder 7. The movement of the steel balls 4 causes the dust filter cylinder 7 to vibrate, which has a better dust removal effect.

[0060] When the temperature and humidity sensor 12 monitors that the temperature inside the electrical cabinet 1 is greater than the set threshold, as mentioned above, the refrigeration component 6 works to cool the steel balls 4. When the air passes through the three-dimensional and mesh-shaped steel balls 4, the air can be fully heat exchanged. The air after heat exchange enters the electrical cabinet 1 to replace the hot air, thereby effectively dissipating the heat inside the electrical cabinet 1.

[0061] At this time, condensed water will appear on the steel balls 4, thereby increasing the ability of the steel balls 4 to absorb dust and achieving a better dust removal effect.

[0062] The rotation of the drive shaft 17 drives the rectangular rod 20 and the reciprocating screw 21 to rotate. The rotation of the reciprocating screw 21 cooperates with the bracket 33 to drive the connecting column 34 and the movable piston 19 to move up and down. When the movable piston 19 moves upward, the air can be sucked into the piston cylinder 10 through the air inlet pipe 24. When the movable piston 19 moves downward, the air can be transported to the air storage box 11 through the air outlet pipe 31, thereby realizing intermittent air supply to the air storage box 11.

[0063] When the pressure in the air storage box 11 is greater than the threshold of the pressure relief valve 23, the pressure relief valve 23 opens, and the high-pressure air is transported to the spray hole 8 through the delivery pipe 22. The spray hole 8 sprays out the high-pressure air and back-blows the dust filter mesh cylinder 7 to clean it, thereby processing the dust in the dust filter mesh cylinder 7 so that it can continue to filter dust.

[0064] The air storage box 11 is supplied with air again. When the air pressure is greater than the threshold value set by the pressure relief valve 23 again, the pressure relief valve 23 is opened again, and the dust filter drum 7 can be back-blown and cleaned intermittently.

[0065] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
