DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 6The present invention provides a technical solution: comprising a cabinet 1, a cabinet door 2 is hingedly connected to the side of the cabinet 1, a base 3 is fixedly connected to the bottom of the cabinet 1, grilles are provided on the front and rear sides of the base 3, an electric push rod 4 is fixedly installed on one side of the interior of the cabinet 1, a reversing arm 5 is slidably connected to the end of the output end of the electric push rod 4, the end of the reversing arm 5 away from the electric push rod 4 is rotatably connected to the middle of the cabinet 1, and a guide groove 6 is provided on the side of the reversing arm 5 close to the electric push rod 4;

[0028] like Figure 2 , Figure 3 As shown, a driving motor 8 is arranged on the back side of the cabinet 1, and an output end of the driving motor 8 is drivingly connected to an air supply pulley group 9, and an end of the air supply pulley group 9 away from the driving motor 8 is rotatably mounted on the cabinet 1, and is fixedly connected to a conical wheel 10, and a conical wheel 2 11 is meshed with a side surface of the conical wheel 10, and the conical wheel 2 11 is rotatably mounted on the mounting frame 7, and a blade 12 is fixedly connected to the conical wheel 2 11;

[0029] The axis of the mounting frame 7 penetrates the conical wheel 10 and is fixedly connected with a swing arm 13, and a guide groove 14 is formed on the swing arm 13, and a side filter 15 is slidably connected in the guide groove 14. The function of the swing arm 13 is to drive the side filter 15 to move downward when the blade 12 swings toward the bottom of the cabinet 1;

[0030] When the cabinet 1 needs to dissipate heat, the electric push rod 4 drives the mounting frame 7 to rotate downward, so that the blade 12 moves downward, and at the same time, drives the swing arm 13 to rotate, so that the swing arm 13 moves the side filter 15 installed on the side of the cabinet 1 downward, so that the side filter 15 enters the water tank 16. When the cabinet 1 dissipates heat, the side filter 15 can be cleaned;

[0031] As 2, Figure 3 As shown, the side filter 15 is slidably connected to the cabinet 1, a water tank 16 is provided on the side of the base 3 perpendicular to the bottom of the filter, a cleaning pulley set 17 is provided on the back side of the base 3, the bottom end of the cleaning pulley set 17 is rotatably connected to the bottom of the air supply pulley set 9, and the top of the cleaning pulley set 17 is rotatably connected to a cleaning roller 18;

[0032] A frame 19 is fixedly connected to the side of the mounting frame 7, and an evaporator 20 and a condenser 21 are fixedly installed on the top of the frame 19. The evaporator 20 is connected to the condenser 21, and a water pipe 22 is connected to the evaporator 20, and an air pipe 23 is connected to the condenser 21.

[0033] The output end of the water pipe 22 is arranged above the cleaning roller 18, and the water flows to the inside of the water tank 16, and the function is to collect the water discharged from the evaporator 20, and use the recovered water to clean the side filter 15;

[0034] The water flow collected by the evaporator 20 is transported to the water tank 16 by the water pipe 22. When the side filter 15 is driven into the water tank 16 by the swing arm 13, the water in the water tank 16 can soak the side filter 15, so that the dust on the side filter 15 is softened and partially falls off, which can facilitate the cleaning roller 18 to clean it.

[0035] like Figure 2 , Figure 4 As shown, the inner surface of the cabinet 1 is fixedly connected to a limit shaft 24, and the limit shaft 24 controls the opening and closing of the frame 19 to meet different needs of dehumidification and heat dissipation;

[0036] The frame 19 is symmetrically provided with air vents 25 extending therethrough, and the top of the frame 19 is provided with an air guide port 26 which is in communication with the evaporator 20 and is used to guide gas into the evaporator 20 when the air vents 25 are closed.

[0037] The two sides of the frame 19 are slidably connected with sealing plates 27, and the connection between the sealing plates 27 and the frame 19 is sleeved with a spring 28, and the side of the sealing plate 27 on one side is fixedly connected with a rack 1 29, and the bottom of the rack 1 29 is meshed with a gear 30, and the gear 30 is rotatably connected to the frame 19, and the bottom of the gear 30 is meshed with a rack 21, and the rack 21 is fixedly connected to the other sealing plate 27, and one of the sealing plates 27 with the rack 1 29 installed abuts against the limit shaft 24;

[0038] A fan 32 is fixedly installed on the back of the cabinet 1. The input end of the fan 32 is connected to the air pipe 23. A diffuser 33 is provided on the back of the cabinet 1 near the output end of the fan 32. The fan 32 is used to pass the dry gas in the condenser 21 to the inside of the cabinet 1.

[0039] When switching between the dehumidification and heat dissipation operations, when the cabinet 1 needs to be dehumidified, the mounting frame 7 swings upward, and during the process, the limit shaft 24 blocks the sealing plate 27 on one side, so that the sealing plate 27 is closed on the frame 19, and the spring 28 is compressed. At the same time, according to the rack 1 29, the gear 30 and the rack 2 31, the sealing plate 27 on the other side is also closed, which can prevent the wet air from contacting the electrical components in the cabinet 1 during dehumidification. After the sealing plate 27 is closed, the air directly enters the interior of the evaporator 20 from the air guide port 26;

[0040] When the cabinet 1 needs to be cooled, the mounting frame 7 moves downward, the blocking of the limit shaft 24 disappears, and the spring 28 opens the two sealing plates 27 when it is released. When air enters from the bottom of the cabinet 1, it can move upward through the vent 25 and perform heat exchange to cool the cabinet 1.

[0041] As 2 and Figure 5As shown, a bottom filter 34 is detachably installed at the bottom of the cabinet 1, and the bottom filter 34 is used to dissipate heat from the cabinet 1;

[0042] When the cabinet 11 is in use, the position of the blade 12 can be controlled by the electric push rod 4 as needed. The blade 12 is placed sideways to dehumidify the cabinet 1, and the blade 12 is placed downward to dissipate heat for the cabinet 1. The air is discharged from the bottom of the cabinet 1, which can improve the air circulation.

[0043] The use method and advantages of the present invention: The working process of the intelligent general high-voltage switch cabinet for mining is as follows:

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown:

[0045] S1: When the humidity inside the cabinet 1 is high, the drive motor 8 is started to drive the air supply pulley group 9 to operate, so that the conical wheel 10 drives the conical wheel 2 11 to rotate, and the blades 12 continue to rotate to absorb the air outside the cabinet 1 into the cabinet 1. At this time, the two sealing plates 27 are in a relatively close position, and the two vents 25 on the frame 19 are closed. When the blades 12 drive the air to contact the frame 19, the air rises upward and enters the evaporator 20 through the air guide port 26. When the humid air flows through the surface of the evaporator 20, the low temperature in the evaporator 20 The low-temperature low-pressure liquid refrigerant absorbs the heat of the air and evaporates, changing from liquid to gas. As the air is cooled, the water vapor in it condenses into water droplets on the surface of the evaporator 20, and the water droplets are discharged through the water pipe 22, thereby achieving dehumidification of the air. The air temperature after dehumidification by the evaporator 20 is relatively low. When passing through the condenser 21, the air absorbs the heat emitted by the condenser 21, and the temperature rises, so that the dry air after dehumidification and temperature increase is sent back to the inside of the cabinet 1 through the fan 32, and the water flow of the evaporator 20 is collected and flows into the water tank 16;

[0046] S2: When it is necessary to adjust to the heat dissipation mode, the output end of the electric push rod 4 is driven to extend outward, so that the mounting frame 7 rotates 90 degrees, and the blade 12 changes from facing the side filter 15 to facing the bottom filter 34, and the two sealing plates 27 are automatically opened, so that the vent 25 is not blocked, and the air enters the cabinet 1 from the bottom of the cabinet 1. During the rising process, the air inside the cabinet 1 is heat-exchanged to reduce the temperature;

[0047] S3: When the blade 12 rotates downward, the swing arm 13 rotates synchronously, so that the side filter 15 moves downward and slides relative to the cabinet 1. When entering the water tank 16, the dust and impurities on the surface are soaked and softened, which is easy to fall off and clean.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
